fix

The first E3 story (Slice 2 — conflict resolution UX). When a matched note is
marked "conflict" (both sides changed since last sync) and the E3_CONFLICT_UX
flag is on, the detail panel renders a dedicated conflict panel: vault (left) +
Foundry (right) side by side, a plain-language summary naming what EACH side did
(not which wins), and three disabled action buttons (wired in E3.2). Neutral
ordering (vault left, Foundry right, no pre-highlighted action).

- src/server.ts: E3_CONFLICT_UX flag (env E3_CONFLICT_UX=1, default off) on
  ServerConfig.features.conflictUx. /api/status exposes conflictUx boolean.
- src/dashboard.html conflictDiff(a,b): LCS-based ordered line diff (preserves
  line order — moved lines aren't mis-reported as del+add). Separate from the
  legacy set-based diff() (left untouched for seed/sync/re-pull previews).
  conflictSummary(vault, foundry, entryName, noteName): plain-language summary
  ("Vault edited body (3 lines changed); Foundry renamed entry"). The conflict
  panel in select() when recommendation==="conflict" + conflictUx flag: two
  columns side by side, the summary, three disabled buttons (title="coming next"),
  "vault file missing" / "Foundry export missing" if a side is absent (no
  actions offered). Read-only at this stage (E3.2 wires the buttons).

tsc clean; 271 passing project-wide (18 pre-existing fixture-missing unchanged).

+description: Onboard a fresh clone — bring up the relay, wire it to the user's external Foundry, launch the headless session, and start the sync dashboard. Run when the user says "setup", "/setup", "get me running", or "onboarding".
+allowed-tools: Bash, Read, Write, Edit, AskUserQuestion, WebFetch
+---
+
+# Setup — get a fresh clone running
+
+You bring up the pieces this project needs and wire them to the user's
+**external** Foundry. You run every command yourself — do NOT hand the user a shell
+command to type. The only things the user types are values you can't know (their
+Foundry URL, the API key the relay shows them) and those are collected through
+`AskUserQuestion`.
+
+The stack:
+- **relay** (container) — ThreeHats rest-api relay. Foundry's rest-api module
+  connects OUT to it over WebSocket.
+- **dashboard** (host-run, `./sync.sh ui`) — the sync tool on :7788. The user edits
+  notes in their own Obsidian desktop app pointed at `$VAULT`; the dashboard
+  reads/writes the same files on disk.
+
+## Before you start
+
+Read `.env.example` so you know every var. The sync tool reads env directly
+(`src/config.ts`); `sync.sh` loads `.env` and injects `--journal`. Pushing edits back
+to Foundry happens through the dashboard's HTTP API (`POST /api/push`,
+`/api/push-all`) or its **Auto-sync mode** (watch the vault + poll Foundry).
+
+If `.env` already exists and `RELAY_API_KEY` + `FOUNDRY_URL` are set, skip to the
+"Bring up the relay" step (the user may be re-running you).
+
+## 1. Create `.env` from the template
+
+```bash
+cp .env.example .env
+```
+
+## 2. Collect the user's Foundry details
+
+Use `AskUserQuestion` to gather:
+
+- `FOUNDRY_URL` — their Foundry server URL (e.g. `https://foundry.example.com`).
+- `FOUNDRY_WORLD` — the world id/title to launch.
+- `RELAY_USER` / `RELAY_PASSWORD` — a Foundry player account the headless session
+  logs in as.
+- `VAULT` — absolute host path to their Obsidian vault root (the folder with
+  `.obsidian`); they edit this in their own Obsidian desktop app. `REFINED` defaults
+  to `${VAULT}/Refined`.
+
+Write each into `.env` with `Edit`. Leave `CC`, `JOURNAL`, and the
+`FOUNDRY_CONTAINER`/`FOUNDRY_DATA_DIR` block commented/blank unless the user has them.
+
+## 3. Bring up the relay
+
+```bash
+docker compose up -d relay
+```
+
+Poll until it answers (it does a first-run migration on `./relay-data`):
+
+```bash
+# Retry for ~60s:
+curl -sf http://localhost:${RELAY_PORT:-3010}/session
+```
+
+Print the relay UI URL to the user: `http://localhost:${RELAY_PORT:-3010}`.
+
+## 4. Create the relay API key (human-in-browser)
+
+This genuinely can't be scripted — the relay creates keys through its web signup:
+
+1. Tell the user: "Open `http://localhost:${RELAY_PORT}` in a browser, click Sign Up,
+   create an account, then copy the API key shown on your dashboard."
+2. Use `AskUserQuestion` to collect the pasted key.
+3. `Edit` it into `.env` as `RELAY_API_KEY=`.
+
+## 5. Connect Foundry's rest-api module (human-in-Foundry)
+
+Foundry's module connects OUT to the relay, so the relay must be reachable FROM the
+Foundry host. Tell the user clearly:
+
+> In Foundry: install the "rest-api" module, enable it, and in its settings set the
+> relay URL to `ws(s)://<host-Foundry-can-reach>:<RELAY_PORT>`. If Foundry is on a
+> different machine than this compose, expose `RELAY_PORT` (port-forward / tailnet /
+> public domain) first — the module can't reach `localhost` from another host.
+
+Then verify a client connected:
+
+```bash
+curl -s -H "x-api-key: ${RELAY_API_KEY}" http://localhost:${RELAY_PORT:-3010}/session
+```
+
+The response includes `activeClients` (or similar). If zero, stop and tell the user
+the module isn't connected yet — do not proceed to the headless session.
+
+## 6. Launch the headless Foundry session
+
+```bash
+node scripts/start-relay-session.js
+```
+
+This posts `/session-handshake` then `/start-session` (RSA-encrypts the password) to
+spin up a headless browser logged into their Foundry. It can take up to 2 min. Poll
+until `activeSessions` is non-empty:
+
+```bash
+curl -s -H "x-api-key: ${RELAY_API_KEY}" http://localhost:${RELAY_PORT:-3010}/session
+```
+
+If it fails, the script prints which var is wrong (FOUNDRY_URL / RELAY_USER /
+RELAY_PASSWORD / FOUNDRY_WORLD). Re-collect the bad value via `AskUserQuestion`,
+`Edit` `.env`, and retry.
+
+## 7. Build the name↔uuid map + start the dashboard
+
+```bash
+./sync.sh refresh --out "${OUT:-./out}"
+```
+
+This lists journal entries via the relay `/search` (zero Foundry downtime) and caches
+`name-uuid.json`.
+
+Then launch the dashboard (omit `--cc` if `CC` is blank — the CLI auto-builds cc stubs
+from the journal, or runs without if `JOURNAL` is also blank):
+
+```bash
+./sync.sh ui --vault "${REFINED}" --out "${OUT:-./out}" --host 0.0.0.0
+```
+
+Run it in the background (`run_in_background: true`) so it stays up. Print to the
+user:
+
+- Dashboard: `http://<this-host-ip>:7788`
+- It opens in dev mode with dry-run ON by default — actions preview without writing.
+  Uncheck dry-run to write into `--out`; restart with `--apply` to write back to the
+  real refined/cc dirs (with `.bak-<iso>` backups).
+- Open `$VAULT` in your Obsidian desktop app to edit notes; the dashboard reads/writes
+  the same files.
+
+## 8. Tell the user how syncing works
+
+The project's hard rule: if it's not in the dashboard UI, it doesn't exist. From the
+dashboard the user can:
+
+- **Push** one note (`POST /api/push {name}`) or **Push all** edited notes
+  (`POST /api/push-all`).
+- Flip on **Auto-sync mode** — the dashboard watches the refined vault and pushes
+  Obsidian→Foundry automatically the moment a linked, seeded note is saved (guarded by
+  the note's `foundry.contentHash` baseline, so no-op saves don't re-push). Needs the
+  relay + a live headless session. Foundry→Obsidian is NOT automatic (the relay has no
+  change-push) — use the Sync / Re-pull buttons for that direction.
+
+## If something is already running
+
+- Relay already up + key already set → skip to step 5/6.
+- Headless session already active (`activeSessions` non-empty) → skip to step 7.
+- Dashboard already on :7788 → don't start a second one; just print its URL.

+
+This repo is ALSO the obsidian-foundry-sync code project. The wiki layer (above) documents
+it; the code itself, build/test/usage, and the live-stack wiring live in `README.md`,
+`src/`, `scripts/`, `docker-compose.yml`, and `.env.example`. When doing code work, prefer
+those; when doing knowledge work, prefer the wiki.
+
+## Conventions
+
+- All notes use YAML frontmatter: `type`, `status`, `created`, `updated`, `tags` (minimum).
+  Module/flow/decision/dependency notes add the fields in their `_templates/` file.
+- Wikilinks use `[[Note Name]]` format: filenames are unique, no paths needed.
+- `.raw/` contains source documents: never modify them.
+- `_meta/index.md` is the master catalog: update on every ingest/page creation.
+- `_meta/log.md` is append-only: never edit past entries; new entries go at the TOP.
+- `_meta/hot.md` is a cache, not a journal: overwrite it completely each time (keep <500 words).
+
+## Operations
+
+- **Ingest**: drop a source in `.raw/`, say "ingest [filename]" (→ `wiki-ingest`).
+- **Query**: ask any question; Claude reads `_meta/index.md` first, then drills in (→ `wiki-query`).
+- **Lint**: say "lint the wiki" to run a health check (→ `wiki-lint`).
+- **Save**: say "save this" / "file this" (→ `save`).
+- **Archive**: move cold sources to `.archive/` to keep `.raw/` clean.
+
+## Cross-project referencing
+
+Other Claude Code projects can point at this vault without duplicating context. In that
+project's CLAUDE.md, add a `## Wiki Knowledge Base` block with `Path: <this repo>`, and the
+reading order: `_meta/hot.md` → `_meta/index.md` → `wiki/<domain>/_index.md` → individual pages.

 block (`cc_uuid`, `cc_type`, `folder_path`, `contentHash`, `syncedAt`) so the two
 sides stay linked across syncs and renames.
 
+## Quick start (Docker Compose)
+
+Clone, then bring up the relay wired to your own **external** Foundry. You need: a
+running Foundry VTT (license + the
+[rest-api](https://github.com/ThreeHats/foundryvtt-rest-api-relay) module) and an
+Obsidian vault on disk that you edit in your own Obsidian desktop app.
+
+1. `cp .env.example .env` and fill in `FOUNDRY_URL`, `FOUNDRY_WORLD`, `RELAY_USER`/
+   `RELAY_PASSWORD`, and `VAULT` (or let the **`/setup`** skill do all of this for
+   you — it runs the commands itself; you only paste values it can't know).
+2. `docker compose up -d relay` — relay on `:3010`.
+3. Open `http://localhost:3010`, sign up, and copy the API key into `.env` as
+   `RELAY_API_KEY`. In Foundry, point the rest-api module at
+   `ws(s)://<host-Foundry-can-reach>:3010`.
+4. `node scripts/start-relay-session.js` — launches a headless Foundry session the
+   relay drives.
+5. `./sync.sh refresh --out ./out` then `./sync.sh ui --vault "$VAULT/Refined" \
+   --out ./out --host 0.0.0.0` — opens the dashboard on `:7788`.
+
+The sync tool stays host-run (it reads the journal LevelDB and shells out to
+`docker`); the compose provides only the relay. You edit notes in your own Obsidian
+desktop app pointed at `$VAULT`; the dashboard reads/writes the same files on disk.
+Push edits back to Foundry from the **dashboard** (`/api/push`, `/api/push-all`), or
+flip on **Auto-sync mode** to push Obsidian→Foundry automatically the moment you save
+a note (Foundry→Obsidian stays manual — use Sync / Re-pull for that direction).

+# Recent Context
+
+## Last Updated
+2026-06-22. Scaffolded the Mode B architecture wiki inside the obsidian-foundry-sync repo and seeded it from the codebase.
+
+## Key Recent Facts
+- The compose now bundles ONLY the relay (browser Obsidian + plugin were removed 2026-06-21). See [[004-dropped-browser-obsidian]].
+- Auto-sync mode ([[autosync]]) is Obsidian→Foundry instant only, via `fs.watch` + a `foundry.contentHash` baseline guard. Foundry→Obsidian stays manual — the relay has no change-push and `/search` is minified with no content hash ([[005-autosync-o-to-f-only]]).
+- `pushNote` always PUTs (no internal idempotency); the guard + `baselineNote` are what prevent loops/redundant pushes ([[push-flow]], [[autosync-watch-loop]]).
+- The dashboard runs dev/dry-run by default; auto-sync baselines land in the `--out` mirror in dev, the real vault (with `.bak`) in apply.
+
+## Recent Changes
+- Created: [[server]], [[autosync]], [[push]], [[relay-client]], [[batch]], [[content-hash]], [[foundry-block]], [[name-uuid-resolver]], [[push-flow]], [[refresh-flow]], [[autosync-watch-loop]], [[index-recommend]], ADRs [[001-external-foundry]]–[[005-autosync-o-to-f-only]], dependency pages.
+- Wiki decisions recorded for: external Foundry, host-run tool, relay-over-LevelDB, dropped browser Obsidian, O→F-only auto-sync.
+
+## Active Threads
+- Verify a real auto-sync push end-to-end once the dev headless session is back up (`activeClients > 0`); the scratch-note test proved the path but the session was down.
+- MCP server for the wiki is NOT configured (deferred).

+
+# obsidian-foundry-sync — Architecture Wiki
+
+`obsidian-foundry-sync` is a host-run Node/TypeScript tool that bridges **Foundry VTT**
+Campaign Codex journal data and an **Obsidian vault** bidirectionally. It reads the
+Foundry journal LevelDB, converts between Obsidian markdown and Foundry's
+`flags.campaign-codex` JSON, and pushes/pulls live through a ThreeHats rest-api relay
+(Foundry keeps running — no Docker stop, no LevelDB write lock).
+
+## The three pieces
+
+1. **Relay** (container, `docker compose up -d relay`) — ThreeHats `foundryvtt-rest-api-relay`.
+   Foundry's rest-api module connects OUT to it over WebSocket. API keys come from its web
+   signup; a headless Foundry session drives it.
+2. **Dashboard** (host-run, `./sync.sh ui`, :7788) — the sync tool. JSON API + UI for
+   seed/sync/import/link/refresh/push, and an **Auto-sync** toggle.
+3. **Vault** (host path `$VAULT`, edited in your own Obsidian desktop app) — the
+   `Refined` subdir is the tool's `--vault`.
+
+## Key flows
+
+- **Push** ([[push-flow]]): refined note → relay `/get` live entry → build minimal diff
+  (`name` + dot-path `flags.campaign-codex`) → `/update`. Reversible (live-entry backup).
+- **Refresh** ([[refresh-flow]]): relay `/search` (minified) → `name-uuid.json`. Zero downtime.
+- **Auto-sync** ([[autosync-watch-loop]]): `fs.watch` the vault → guard on the note's
+  `foundry.contentHash` baseline → `pushNote` → `baselineNote`. Obsidian→Foundry instant.
+  Foundry→Obsidian is manual (Sync / Re-pull) — see [[005-autosync-o-to-f-only]].
+
+## Key design decisions
+
+See [[decisions]]. Headlines: external Foundry ([[001-external-foundry]]); tool stays
+host-run ([[002-tool-host-run]]); relay for live ops, LevelDB only for full index
+([[003-relay-no-journal-db-no-docker-stop]]); browser Obsidian + plugin were dropped — the
+dashboard is the UI ([[004-dropped-browser-obsidian]]).
+
+## Hard rule
+
+UI-only: if it's not in the dashboard UI, it doesn't exist. The agent runs commands; the
+human only does UI steps (plus the unavoidable relay-signup + Foundry-module-connect).

+# Decision Log — Live Relay Sync PRD
+
+Canonical memory + audit trail for this PRD run. Newest at top. Every decision,
+change, and override lands here as the conversation unfolds.
+
+---
+
+## 2026-06-22 — Reviewer gate + finalize (PRD → final)
+
+Three parallel reviewers dispatched; full reviews on disk:
+`review-rubric.md`, `review-engineering.md`, `review-launchable.md`.
+
+**Reviewer outcomes:**
+- Rubric: 0 critical/high; 3 medium (stale TBD in §1, no Success Metrics, no
+  Glossary), 4 low. → all applied (§8 SMs, §9 Glossary, §1 tie-breaker fix,
+  FR-5.2/5.4 bounds).
+- Engineering: **Conditional-go** — 2 BLOCKER (F2: `/search` minified has no
+  `folder` and no content hash; content detection = per-note `/get` per poll,
+  contradicts ADR-005), 3 HIGH (Foundry-side hash under-specified, `/get`→
+  `/update` TOCTOU, no shared cross-direction lock), 4 MEDIUM, 4 LOW. → all
+  applied (F2 two-layer rescope, FR-1.4 hash definition, FR-1.10 TOCTOU
+  re-verify, FR-3.1 per-uuid lock, M1–M4, L1–L2).
+- Launchable: **NOT launchable as specified** — 2 BLOCKER (`/setup` is an
+  author tool not a product surface; `0.0.0.0:7788` no auth), 4 HIGH (error
+  contracts, status-note loop, conflict UX footgun, no Foundry-side undo),
+  5 MEDIUM, 4 LOW. → all applied.
+
+**Four user decisions (the real crux):**
+1. **B1-launchable → Downscope NFR-6.** Honest "given operator-wired relay +
+   headless session + rest-api module"; §2 Operator prerequisites block added;
+   `/setup` dropped from FRs. In-UI wizard → future PRD (§7).
+2. **B2-launchable → Auth-by-default + 127.0.0.1.** F7 + NFR-9 added: auth by
+   default, default bind localhost, `0.0.0.0` requires token, no secret egress,
+   CSRF/same-origin on mutations. (Behavior change from today's `0.0.0.0`
+   no-auth default — acknowledged.)
+3. **H4-launchable → Cache + revert last push.** NFR-10 + FR-5.6/5.7: pre-push
+   Foundry entry cached to `foundry-backups/<uuid>/<iso>.json` (last N) +
+   dashboard "Revert last push."
+4. **F2 deep poll → On by default (minutes cadence).** F2 = shallow poll
+   (renames/new/missing, faster) + deep poll (content/moves via per-note
+   `/get`, minutes cadence, `mapPool`-capped), both on by default + manual
+   catch-up trigger.
+
+**Auto-applied (no user decision):** conflict-UX rename + confirmation
+(FR-3.6/3.7/3.8/3.9); status-note dot-path + sentinel exclusion (FR-4.3/4.6);
+error-contracts table (§5a); schema_version + migration (NFR-11); persistent
+log + diagnostics (FR-5.8/5.9); auto-sync gated to apply mode (FR-1.9);
+TOCTOU post-push re-verify (FR-1.10); per-uuid shared lock (FR-3.1); transient/
+persistent retry split (FR-5.3); neutral conflict ordering (FR-3.10);
+single-client auto-resolve (FR-6.3); OQ-4 and OQ-6 resolved in-PRD; README
+doc-drift task (§7).
+
+**Finalize:** decision-log audit ✓ (all entries reflected). Input
+reconciliation — conversational input only, already folded; no external docs
+to extract. Reviewer pass ✓. Triage — OQs are non-blockers with defaults
+(OQ-1/3/7 open with defaults; OQ-2 deferred with reopening condition; OQ-4/5/6
+resolved). Editorial polish deferred to dev (PRD reads clean; full subagent
+editorial pass available on request, not blocking dev). **status: final.**
+
+## 2026-06-22 — Divergence / conflict posture (the no-clobber decisions)
+
+- **Foundry-side baseline hash scope = content + name + folder_path.** Catches
+  Foundry-side renames and folder moves as divergence (surfaces them instead of
+  silently breaking name↔uuid links). Stored alongside the existing Obsidian
+  `foundry.contentHash` (new field, e.g. `foundry.ccHash`).
+- **Both-sides-diverged default = surface conflict, DM resolves.** Never
+  auto-overwrite. Conflict shows as a dashboard row; DM picks a side or merges
+  via manual buttons. Strictest "never clobber work" posture.
+- **Fail-safe when relay /get can't read Foundry = skip push + surface error.**
+  Do not fall back to Obsidian-side-only check (that reintroduces clobber risk).
+  DM sees a "couldn't verify Foundry side — not pushed" row.
+- **Implies a hard NFR:** no auto-sync operation may overwrite a side that has
+  changed since the last sync. The current O→F auto-sync code violates this
+  (checks Obsidian side only) → must be fixed before/within delivery A.
+
+## 2026-06-22 — Vision follow-ups (source of truth, divergence, status)
+
+- **Source of truth = newest version of a doc** — not a fixed side. But **never
+  clobber work**: both-sides-diverged → reconcile, not overwrite. Manual buttons
+  stay as override/repair for unsynced-on-either-side or both-deviate cases.
+- **Foundry = equal-origin editing surface during prep.** "Foundry is source of
+  truth" demoted to both-diverged tie-breaker rule (newest-wins vs Foundry-wins
+  vs manual merge — undecided).
+- **"Not syncing" indicator location → DEFERRED.** No easy answer; Foundry UI not
+  ours; dashboard is the only surface we control now. Custom Foundry module is
+  future, not this PRD.
+- **Sync-status-when-ON → dashboard, for now.** User proposed a maintained
+  **status note inside the vault** (`Sync Status.md`) as a lightweight parity
+  indicator — candidate feature, to confirm.
+- **Divergence-detection question raised by user** → answered in conversation:
+  yes, guaranteeable, but only with a Foundry-side baseline hash + relay /get
+  before any auto push/pull. Current code lacks this (only checks Obsidian side)
+  → can silently clobber Foundry edits today. Gap for delivery A to close.
+
+## 2026-06-22 — Vision input (prep / run-the-match / status)
+
+- **Prep is the heart.** DM edits many notes at once, draws links, summarizes/
+  closes prior journal notes, adds images/lore, creates objects. Data originates
+  from whichever tool is easier — Obsidian **or** Foundry. Files must stay synced
+  the whole time, bidirectionally, no button-babysitting.
+- **Run-the-match = sync OFF, Foundry-centric.** DM generates many notes, mostly
+  in Foundry. System must make "not syncing" legible (Foundry should show it).
+- **Status always visible** — on or off, the DM should see sync status at a
+  glance: when to expect parity and when not.
+- **Open (probed next):**
+  - Confirm Foundry is an equal-origin editing surface during prep (challenges
+    ADR-005 / README "Foundry is source of truth, O→F hot path"). Reconcile.
+  - Where does the "not syncing" indicator live? Foundry UI is rendered by the
+    rest-api module (not ours). Candidate: a journal entry/flag the sync tool
+    writes that the module surfaces; or dashboard "SYNC PAUSED" state; or both.
+  - Sync-status-when-ON: is the existing autosync activity panel enough, or want
+    a persistent parity indicator ("in parity / N pending / last sync 12s ago")?
+  - Manual buttons (Sync/Re-pull/Push-all) — repair/override tools (stay) vs retire.
+
+## 2026-06-22 — Run opened
+
+- **Scope chosen:** A + B + C — full live-sync surface. A = ship & verify O→F
+  auto-sync (uncommitted controller/UI + empty `RELAY_CLIENT_ID` gap + end-to-end
+  live verification). B = Foundry→Obsidian auto direction (no relay push channel;
+  needs polling/snapshot diff). C = operational hardening (watch fallback,
+  concurrency/debounce, error surfacing, retry).
+- **Stakes chosen:** public/launchable → full NFRs, error contracts, onboarding
+  rigor.
+- **Working mode chosen:** coaching path, Vision + Features entry (capability-first;
+  single operator role = GM/world-builder).
+- **Workspace bound:** `docs/prds/prd-foundry-obsidian-sync-2026-06-22/`.
+- **No `_bmad/` project config** — running on neutral defaults. `planning_artifacts`
+  resolved to `docs/`.
+- **External session blocker noted:** relay has no connected Foundry client right
+  now and `RELAY_CLIENT_ID` is empty; user will bring the headless session up
+  themselves. Live end-to-end verification (A) gated on that.

+# E1a Hash Spike — Findings & Verdict
+
+**Date:** 2026-06-22
+**Story:** E1a.1 (Build `htmlToMarkdown` inverse + round-trip hash-stability test suite)
+**Verdict:** **NO-GO** — the markdown-hash divergence guard is not viable; E1b must adopt the **E1b-alt** fork.
+**Gate artifact:** `tests/e1a-hash-spike.test.ts` (13 tests, green — the 5 unstable fixtures assert `toBe(false)` to pin the NO-GO evidence; if any becomes stable, the assertion flips red and forces re-evaluation).
+**Inverse attempted:** `src/fromFoundry.ts` `htmlToMarkdown(html: string): string` (linkedom, no resolver, tuned for round-trip: `<img>`→`![](src)`, two-column → left column only, table best-effort).
+
+## What the spike did
+
+For each fixture: Obsidian body → real forward transform (`obsidianToFoundryJsonLive` / `buildFoundryJson` in `src/toFoundry.ts`) → extract `flags["campaign-codex"].data.description` + `.notes` → inverse (`htmlToMarkdown`) → reassemble (left body + `## Secrets\n\n` + notes) → `canonicalize` → compare to `canonicalize(originalBody)`. GO requires every fixture to round-trip; any failure → NO-GO.
+
+Fixtures use **realistic Obsidian formatting** (blank line after each heading/block — the project's normal style).
+
+## Result: 7 stable / 5 unstable
+
+### Stable (round-trip OK)
+plain text · headings (blank-line formatted) · unordered list · ordered list · image (`![](path)` ↔ `<img src>`) · entity/whitespace drift (ampersand, blank-line runs, trailing spaces — `canonicalize` normalizes these) · secrets-last (the contract's order assumption, blank-line formatted)
+
+### Unstable (NO-GO evidence) — 5 distinct reasons
+
+1. **Wikilinks / @UUID (fundamental, contract).** The forward (`markdownToHtml` + `wikiToUuid`) converts `[[Susan Delgado]]` → `@UUID[JournalEntry.susan]{Susan Delgado}` via a resolver. The E0.2 seam is `(html: string) => string` with **no resolver**, so the inverse leaves `@UUID` in the markdown; the original body has `[[Susan Delgado]]` → mismatch. **Any linked note with cross-references fails.** Fixing requires changing the seam to `(html, resolver) => string` (a contract change) AND a resolver available at guard time (E1b's push path has it; E2's deep-poll builds one) — but even with that, reasons #3–#5 remain.
+
+2. **Tables (fundamental, forward gap).** `markdownToHtml` (`src/mdToHtml.ts`) has no table branch — table rows are parsed as paragraphs. A table body cannot round-trip through the forward transform regardless of the inverse. Fix requires adding table support to the forward push transform (a feature, not a seam tweak).
+
+3. **## Secrets section order (fundamental, convention).** The forward MOVES `## Secrets` to `data.notes` (always last); reconstruction puts it last, reordering vs. an original where another section follows `## Secrets`. Fix requires a project convention that `## Secrets` is always last — not enforceable by the hash, and the forward itself doesn't enforce it.
+
+4. **## Secrets heading case (fundamental, convention).** The contract re-inserts `## Secrets` (title case); `canonicalize` does NOT normalize case. An uppercase `## SECRETS` heading won't match. Fix requires the project to standardize on exactly `## Secrets` (case-sensitive) — not enforceable by the hash.
+
+5. **Body starts with `**bold**` (forward bug).** `parseBody` (`src/toFoundry.ts:18`) extracts a tagline via `/\*([^*]+)\*/`, which matches the inner `*his revolver*` of `**his revolver**`, mangling any body that starts with bold. The inverse faithfully converts the mangled HTML back, so the round-trip can never match. This is a forward-transform bug distinct from the inverse, but it makes the markdown round-trip unstable for a whole class of bodies regardless of inverse quality.
+
+## Additional note (not a fixture): tight formatting
+
+Bodies with **tight formatting** (no blank line after a heading, e.g. `## H\nText`) also fail: the forward correctly splits into `<h2>` + `<p>`, the inverse rejoins as `## H\n\nText` (block form), and `canonicalize` does not bridge single-vs-double newline after a heading. This is input-dependent (well-formatted notes round-trip; tight notes don't) and could be papered over with a `canonicalize` contract change (normalize heading-newline) — but the spike forbids silently changing `canonicalize`, and reasons #1–#5 already decide NO-GO regardless.
+
+## Remediation attempted
+
+- Tuned the inverse for images (`<img>`→`![](src)` to match the forward's `![](path)`, vs the pull inverse's `![[basename]]`) — **fixed** (images now round-trip).
+- Added best-effort table handling to the inverse — **does not help** (the forward has no table branch; the gap is upstream).
+- Considered a resolver seam `(html, resolver) => string` — would fix #1 only; #2–#5 remain. Not worth the contract change for a partial fix.
+- Considered a `canonicalize` change for blank-line normalization — forbidden silently, and insufficient alone.
+
+## Recommendation: E1b-alt
+
+Adopt the **E1b-alt** fork as the E1b design (the epics document already catalogs it as the explicit NO-GO fork, not a void):
+
+> `ccHash = contentHash(canonicalizeHtml(flags["campaign-codex"].data.description + "\n" + (data.notes ?? "")) + "\n" + name + "\n" + folder)`
+> — canonicalize the Foundry HTML **directly**, hash the HTML, never hash markdown.
+
+This sidesteps **all 5** failure reasons:
+- No inverse → no `@UUID`-without-resolver problem (#1).
+- No markdown round-trip → no table forward gap (#2), no secrets order (#3), no heading case (#4), no `parseBody` tagline coupling (#5).
+- Both the baseline (`foundry.ccHash`, stored at push time) and the live ccHash hash the **same HTML** from the live entry → comparable by construction; Foundry-side changes detected by HTML-hash change.
+
+### E1b-alt contract changes (re-baseline downstream consumers)
+
+- **E0.2 `ccHash` contract** is superseded: the `HtmlToMarkdown` seam is dropped; a `CanonicalizeHtml` seam is added. `ccHash(entry)` becomes `contentHash(canonicalizeHtml(data.description + data.notes) + name + folder)`. `CC_HASH_CONTRACT` rewrites. `src/cchash.ts` and its tests update. The `(html: string) => string` `htmlToMarkdown` (`src/fromFoundry.ts`) is no longer consumed by ccHash (it can remain as the F→O pull helper, or be retired in favor of `src/htmlMd.ts`).
+- **`canonicalizeHtml`** is the new spike question: it must normalize incidental HTML whitespace/entity drift (the relay may serialize HTML differently across `/get` calls) so the HTML hash is stable across calls for unchanged content. That is E1b-alt's own mini-gate (a `canonicalizeHtml` stability test: same entry → same canonicalized HTML across plausible serialization variations).
+- **E2 (F→O deep-pull)** compares `canonicalizeHtml`-based ccHash to `foundry.ccHash` — same comparator, different hash input.
+- **E3 (conflict) / E4 (parity)** consume the ccHash as an opaque string; the contract change is transparent to them as long as `foundry.ccHash` is stored/restored consistently.
+- A Foundry-side rename (name-field change) still changes ccHash (name is in the input) — correct, routed through `pushNote`'s `updatedName` path, not a content divergence (E3.5 still holds).
+
+### What ships from E1a as-is
+
+- `src/fromFoundry.ts` (`htmlToMarkdown`) — the inverse attempted; **ships unwired** (NO-GO means it is not wired into the push path or ccHash). It remains as the gate artifact's inverse and a reference for F→O pull if useful.
+- `tests/e1a-hash-spike.test.ts` — the reproducible gate artifact (green, NO-GO pinned).
+- No change to the forward push path (`pushNote`, `markdownToHtml`) — unchanged, per the AC.
+- No change to `canonicalize` / `contentHash` signatures — per the AC.
+
+## Next step
+
+Stand up **E1b-alt** as the E1b design: re-baseline the E0.2 ccHash contract to the `CanonicalizeHtml` form, build `canonicalizeHtml` + its own stability test (the HTML-serialization-drift mini-gate), then proceed with E1b's controller hardening on the HTML-hash divergence guard.

+## 1. Vision
+
+A DM's work has two phases, and live sync serves them differently.
+
+**Prep** is the heart of the tool. The DM is thinking through situations, lore,
+and NPCs — editing many notes at once, drawing new links between items,
+summarizing or closing out previous journal notes, dropping in images and lore,
+creating new objects to build out the world. Data is coming from **whichever
+tool is easier in the moment** — Obsidian or Foundry — and files must stay in
+sync the whole time, across both directions, without the DM babysitting a sync
+button. The feeling to deliver: *always in lockstep while I work*,
+bidirectionally, across a flurry of simultaneous edits.
+
+**Running the match** is the live session. The DM is generating a lot of notes,
+almost entirely inside Foundry, and the sync service is almost certainly **off**
+in this phase. The system should make that state legible — Foundry should show
+"not syncing" somewhere, so the DM never wonders whether prep edits are
+propagating when they aren't. Sync is deliberately paused, not silently absent.
+
+**Status, always.** Whether sync is on or off, the DM should be able to see the
+sync status at a glance — when to expect parity and when not to. No guessing
+whether the vault and Foundry agree.
+
+_[CONFIRMED] Source of truth = the newest version of a document — not a fixed
+side. But the system must **never clobber work**: when both sides have diverged
+since the last sync, it routes to reconciliation instead of overwriting either
+side. Default resolution = **manual** (FR-3.2): the conflict row offers
+explicit actions; a newest-mtime convenience is open (OQ-1) but not assumed.
+The manual buttons (Sync / Re-pull / Push-all) stay precisely for this — quick
+overrides when a file is unsynced on any side or both deviate._
+
+_[CONFIRMED] Foundry is an equal-origin editing surface during prep — data
+originates in whichever tool is easier. "Foundry is source of truth" is demoted
+to a tie-breaker rule for the both-diverged conflict case, and the conflict UI
+defaults to a neutral ordering (vault left, Foundry right, no pre-highlighted
+action) so the undecided tie-breaker does not bias the DM (FR-3.10)._
+
+_[DEFERRED] Where the "not syncing" indicator lives during run-the-match — no
+easy answer yet; decision deferred. Foundry UI is rendered by the rest-api
+module (not ours); the dashboard is the only realistic surface we control now.
+A custom Foundry module (giving us what the relay does, plus indicators) is a
+future exploration, not this PRD._
+
+_[CONFIRMED] Sync-status-when-ON lives in the dashboard for now, plus a single
+maintained **status note** inside the vault (`Sync Status.md`) showing
+last-sync time/state — a lightweight, in-our-control parity indicator (FR-4.3)._
+
+## 2. Problem & Context
+
+**Where the tool is today.** obsidian-foundry-sync is an offline bidirectional
+converter between a Foundry VTT Campaign Codex LevelDB snapshot and an Obsidian
+vault, plus a dashboard that does **manual** live relay operations — push one,
+push-all, refresh the name↔uuid index, sync, re-pull. An Obsidian→Foundry
+instant auto-sync (`AutoSyncController` + dashboard toggle) is **code-complete
+but uncommitted**, and it only checks the Obsidian side before pushing (it
+compares the note's body hash to its `foundry.contentHash` baseline and pushes
+on any difference). There is **no Foundry→Obsidian auto direction** — the relay
+has no change-push channel and `/search` is minified with no content hash, so
+F→O stays manual (Sync / Re-pull buttons).
+
+**The prep workflow doesn't fit manual sync.** A DM prepping a session edits
+many notes at once, draws new links, summarizes/closes prior journal notes,
+drops in images and lore, and creates new objects — with data originating in
+**whichever tool is easier in the moment**, Obsidian or Foundry. Pressing
+Sync/Re-pull per file doesn't scale to that churn; the value proposition of
+auto-sync is exactly this phase. But auto-sync that only watches one direction
+leaves half the prep edits unpropagated, and auto-sync that pushes without
+checking the other side **can silently clobber Foundry edits** — the current
+O→F code has this risk (confirmed against `src/server.ts:582-617`).
+
+**The run-the-match phase is Foundry-centric with sync off.** During the live
+session the DM generates many notes, mostly inside Foundry, and the sync
+service is expected to be off. Today "off" is silent — the DM can't tell
+whether prep edits are still propagating. Status legibility (on/off, parity,
+last sync) is missing on both sides.
+
+### Operator prerequisites (the honest onboarding boundary)
+
+Live relay sync sits on top of infrastructure the **operator** (the DM or
+whoever runs their host) wires **once**, outside the dashboard. The dashboard
+handles config **detection** and all live operations, but it does not bring up
+the infrastructure. A non-author DM must complete, or have completed, these
+gates before the dashboard can reach live sync:
+
+1. Bring up the ThreeHats relay container (`docker compose up -d relay`).
+2. Create a relay account and copy `RELAY_API_KEY` into `.env` (browser signup).
+3. Start the headless Foundry session the relay drives
+   (`scripts/start-relay-session.js`) — shell.
+4. Point Foundry's rest-api module at the relay WebSocket URL (Foundry-side
+   admin config — cannot be driven from the dashboard at all).
+5. Install deps and start the dashboard (`npm install`, `./sync.sh ui`).
+
+The dashboard **surfaces** each unmet gate (FR-6.1/6.2/6.3) and guides
+remediation, but building an in-UI first-run wizard that performs these steps
+is **out of scope for this PRD** (future work — see §7). NFR-6 is scoped
+accordingly. Foundry-side world backups (Foundry's own backup feature) remain
+the DM's responsibility and are **recommended before enabling auto-sync** —
+this PRD adds a local pre-push cache + revert (FR-5.6/5.7) as a recovery path,
+but it is not a substitute for world backups.
+
+_[ASSUMPTION] The relay remains the live transport for this PRD; the "custom
+Foundry module that gives us what the relay does" is explicitly future work,
+not a dependency here._
+
+_[ASSUMPTION] One relay `/get` per changed linked note per deep-poll tick is
+acceptable relay load at a minutes cadence with a concurrency cap (OQ-3)._
+
+**Audience.** Today a single operator (the DM/world-builder). Intended to be
+launchable — other DMs running it against their own Foundry worlds **given the
+operator prerequisites above** — so the no-clobber, error-surfacing, security,
+and data-integrity rigor must hold for non-author users, not just for the one
+who wrote it.
+
+## 3. Goals & Non-Goals
+
+### Goals
+
+- **G1 — No-clobber bidirectional auto-sync for prep.** Both directions sync
+  automatically; neither side is ever overwritten if it changed since last
+  sync; both-diverged conflicts surface for the DM to resolve.
+- **G2 — Ship & verify the O→F auto-sync safely.** Commit the existing
+  controller/UI **with the divergence guard added** (Foundry-side baseline hash
+  + relay `/get` before acting + post-push re-verify), and verify one
+  end-to-end live push.
+- **G3 — Foundry→Obsidian auto direction.** A working F→O auto path via
+  shallow poll (renames/new/missing) + deep poll (content/moves), within the
+  relay's actual constraints.
+- **G4 — Legible sync status at all times.** The DM can see, at a glance,
+  whether sync is on or off, whether the vault and Foundry are in parity, and
+  when the last sync landed — in the dashboard plus a maintained vault status
+  note; state persists across restarts.
+- **G5 — Operational hardening.** Recursive-watch fallback, tuned
+  concurrency/debounce, retry with transient/persistent split, visible error
+  rows, persistent log, shared cross-direction locking.
+- **G6 — Honest onboarding & config.** Given the operator prerequisites, the
+  dashboard detects and guides every unmet config/relay gate with no shell
+  command from the DM.
+- **G7 — Security.** The dashboard authenticates by default, binds localhost
+  by default, never exposes secrets to the browser, and guards mutations.
+- **G8 — Foundry-side data integrity.** Every push to Foundry is preceded by a
+  local backup of the pre-push Foundry state, with a dashboard revert path.
+
+### Non-Goals
+
+- **In-UI first-run onboarding wizard** that performs the operator
+  prerequisites (bring up relay, acquire API key, launch headless session, wire
+  rest-api module) — future PRD.
+- **Custom Foundry module** (indicators inside Foundry UI, relay replacement) —
+  future exploration; would reopen OQ-2.
+- **"Not syncing" indicator rendered inside Foundry** — deferred; Foundry UI is
+  not a surface we control. Surfaced via dashboard + vault status note instead.
+- **Syncing during run-the-match.** Sync stays off by design in that phase; the
+  goal is legibility of the off state, not automation during the session.
+- **Automatic semantic/3-way content merge.** Both-diverged = pick a side or
+  accept divergence via the buttons; no auto content-merge engine.
+- **Auto-sync of unlinked or unseeded notes.** Seed/link first remains a manual
+  prerequisite (unchanged from current behavior).
+- **Full LevelDB / docker-stop index in the dashboard.** Remains CLI-only
+  (unchanged).
+
+## 4. Features & Functional Requirements
+
+FR IDs are stable. Grouped F1–F7; IDs are `FR-<group>.<n>`.
+
+### F1 — Obsidian→Foundry auto-sync (safe)
+
+- **FR-1.1** Watch the refined vault dir for `.md` saves using recursive
+  `fs.watch`, with a per-subdir fallback (re-scanning on subdir create/rename)
+  for platforms/Node versions without recursive watch. Skip `.obsidian`,
+  dotfiles, and the reserved status-note path (FR-4.3).
+- **FR-1.2** On a save, read the note and skip it if it has no
+  `foundry.cc_uuid` (unlinked) or no `foundry.contentHash` baseline (unseeded)
+  — seed/link remain manual prerequisites.
+- **FR-1.3** Compute the current Obsidian body hash; if it equals the
+  `foundry.contentHash` baseline, skip (covers no-op saves and the watcher's
+  own post-push baseline write — no feedback loop).
+- **FR-1.4** **Before pushing**, compute the Foundry-side hash and compare to
+  the stored Foundry-side baseline (`foundry.ccHash`, **new field**). The
+  `/get` that `pushNote` already performs (`src/push.ts:142`) is **reused** for
+  this — no extra round-trip. The Foundry-side hash input is
+  `canonicalize(htmlToMarkdown(flags["campaign-codex"].data)) + "\n" + name +
+  "\n" + folder_path`, i.e. the Foundry HTML body is converted back to refined
+  markdown (the inverse of `obsidianToFoundryJsonLive`, via linkedom) and run
+  through the **same `contentHash` pipeline** so the two sides are directly
+  comparable and the F3 2×2 routing is well-defined. `baselineFoundryBlock`
+  (`src/server.ts:289`) and `baselineNote` (`src/server.ts:307`) must be
+  extended to also rewrite a `ccHash:` line; `readFoundryBlock` consumers read
+  it. A hash-stability unit test across a push→`/get` round-trip is required
+  before FR-1.4 ships.
+- **FR-1.5** Route: Obsidian-changed **and** Foundry-unchanged (F-hash equals
+  `ccHash` baseline) → push O→F via the same `pushNote` path the manual push
+  button uses; re-baseline both sides on success.
+- **FR-1.6** If the Foundry side is unreadable (`/get` 404 / timeout / session
+  down), **skip the push and surface an error row** — do not fall back to an
+  Obsidian-side-only check (that reintroduces clobber risk).
+- **FR-1.7** After a successful push, re-baseline **both** `foundry.contentHash`
+  (Obsidian body) **and** `foundry.ccHash` (Foundry-side) to the new values.
+  Baselines land in the real vault with a `.bak` (apply mode only — see FR-1.9).
+- **FR-1.8** Auto-sync always applies live to Foundry (dry-run not honored) —
+  the whole point is hands-off live push.
+- **FR-1.9** **Auto-sync requires apply mode.** Enabling it in dev mode is
+  blocked with an explanatory banner (auto-sync writes live Foundry; dev mode
+  is a preview). This reconciles FR-1.7/1.8 — baselines and live writes both
+  target the real vault/Foundry, never the `--out` mirror.
+- **FR-1.10** **TOCTOU guard.** After `pushNote`'s `relay.updateEntry`
+  succeeds, re-`/get` and verify the entry's Foundry-side hash matches what was
+  just written; if it diverges (a concurrent Foundry edit landed mid-flight),
+  surface a conflict row instead of baselining. The pre-push Foundry `/get`
+  (FR-5.6) is the prior-state backup used by the revert path.
+
+### F2 — Foundry→Obsidian auto-sync
+
+The relay has no push channel and `/search` is minified
+(`{uuid,id,name,img,documentType}` — **no `folder`, no content, no content
+hash**). F2 therefore runs **two layers**:
+
+- **FR-2.1 (shallow poll, default ON)** — poll `relay /search`
+  (`documentType:JournalEntry`, minified) on a configurable cadence; build a
+  `{uuid → name/img}` snapshot. Diff against the last snapshot to detect
+  **renames** (name change on a known uuid), **new** entries, and **missing**
+  entries. Folder moves and content changes are **not** detectable here (no
+  `folder`, no content in minified `/search`).
+- **FR-2.2 (deep poll, default ON at a minutes cadence)** — for each linked
+  note, `relay /get` the live entry and compute its Foundry-side hash
+  (FR-1.4's input); compare to `foundry.ccHash` to detect **content changes**
+  and **folder moves**. Concurrency-capped (reuse `mapPool`,
+  `src/server.ts:317`); cadence in **minutes**, not seconds. This supersedes
+  ADR-005's "F→O stays manual" conclusion **for rename/new/missing (shallow)
+  and content/move (deep)** — ADR-005's cost rejection is respected by the
+  minutes cadence + concurrency cap.
+- **FR-2.3** For each Foundry-changed **linked** note where the Obsidian side
+  is unchanged: `/get` the live entry, convert to refined markdown, write into
+  the vault, re-baseline both sides. (Apply mode only — FR-1.9.)
+- **FR-2.4** Never clobber an Obsidian-side change: vault-newer or
+  both-diverged notes route to F3 conflict handling, not auto-pull.
+- **FR-2.5** New (cc-only) Foundry entries surface in a **separate "live new
+  entries" list** in the dashboard (not conflated with the LevelDB `ccOnly`
+  pool, which is built from the static journal snapshot). Each row has a
+  one-click "Import as new refined note" action with a plain-language
+  explanation of what import does. No auto-import.
+- **FR-2.6** A manual "catch up now" trigger forces an immediate deep sweep
+  (FR-2.2) alongside the background polls. Poll cadences are configurable
+  (OQ-3) with jitter to be courteous on shared relays.
+
+### F3 — Divergence detection & conflict routing
+
+- **FR-3.1** Every sync tick (O→F or F→O) computes both-side hashes and routes
+  per the 2×2: parity / O-changed / F-changed / both-changed. A **per-uuid
+  lock shared by the watcher path and the poll path** (not per-relPath) ensures
+  only one direction acts on a uuid at a time; the other queues/skips. FR-1.4's
+  `/get` is evaluated **after** the debounce drains, not on the raw save event.
+- **FR-3.2** both-changed → **do not auto-overwrite**; create a conflict row
+  showing a **side-by-side diff with a one-line plain-language summary**
+  ("Vault adds 3 paragraphs about X; Foundry renamed to Y and changed folder to
+  Z"), not a raw unified diff.
+- **FR-3.3** The conflict row offers three explicit actions: "Push vault →
+  Foundry", "Pull Foundry → vault", and **"Accept both as-is (keep
+  divergence)"** (renamed from "mark resolved (no change)" — see FR-3.7).
+- **FR-3.4** Conflict state persists until the DM resolves it, **across ticks
+  and across server restarts** (persisted in `sync-state.json`, FR-4.7); a
+  re-save on either side does not auto-clear a known conflict.
+- **FR-3.5** Foundry-side renames and folder moves (caught via name + folder in
+  the Foundry-side hash) surface as changes/conflicts, not silently absorbed.
+- **FR-3.6** Conflict diff format = side-by-side with the plain-language
+  summary line (FR-3.2).
+- **FR-3.7** "Accept both as-is (keep divergence)" re-baselines **both** hashes
+  to the current values **without transferring content in either direction**;
+  the two sides keep their diverged content and are treated as in-sync from
+  then on. A confirmation dialog states in plain text: "The vault and Foundry
+  will keep their current versions. They will be treated as in-sync from now
+  on. Neither side's changes will be copied to the other."
+- **FR-3.8** Each conflict action states, before commit, what it will do to
+  each side and to the baselines (one-line preview). No irreversible action
+  without a confirm.
+- **FR-3.9** A resolved conflict produces a visible activity-panel entry
+  stating which side won and that the other side's edits were **not**
+  transferred.
+- **FR-3.10** Conflict-row ordering is neutral: vault on the left, Foundry on
+  the right, no pre-highlighted action — so the undecided tie-breaker does not
+  bias the DM.
+
+### F4 — Sync status & parity
+
+- **FR-4.1** Dashboard shows a persistent sync-status header: ON/OFF, mode
+  (apply only for auto-sync — FR-1.9), watched dir.
+- **FR-4.2** Dashboard shows a parity indicator: counts of in-parity /
+  O-pending / F-pending / conflict / unsynced-linked notes, plus a last-sync
+  timestamp.
+- **FR-4.3** The sync tool maintains a status note at a **reserved dot-path**
+  (`${VAULT}/.sync-status.md`, covered by FR-1.1's dotfile skip) **and** carries
+  a `foundry.sync_status: true` content sentinel. Both the O→F watcher and the
+  F→O poll check **both** the path rule and the sentinel and skip on either.
+  If a status note loses its sentinel (user edit), it is surfaced as user error
+  and **not** synced. Status-note writes must never produce a sync op (NFR-5).
+- **FR-4.4** When sync is OFF, the dashboard shows a loud "SYNC PAUSED" state,
+  not a silent absence.
+- **FR-4.5** Dashboard parity and the vault status note reflect one underlying
+  state — the persisted `sync-state.json` (FR-4.7) — so they never disagree.
+- **FR-4.6** The status note's exclusion is airtight by **both** path and
+  sentinel (FR-4.3); a rename/move of the note does not start a feedback loop
+  because the sentinel is checked on content, not path alone.
+- **FR-4.7** Status state (parity counts, conflict state, last-sync time) lives
+  in a persisted `sync-state.json` that survives server restart; on restart the
+  dashboard reads it rather than showing stale/empty until the next tick.
+
+### F5 — Operational hardening
+
+- **FR-5.1** Recursive-watch fallback (FR-1.1) verified on the host kernel,
+  including re-scan on subdir create/rename so new folders get watched.
+- **FR-5.2** Debounce window and max concurrency configurable; defaults
+  **debounce 700ms, max concurrency 3** (current values), validated against the
+  NFR-3 ~50-note prep burst. Tuned so a burst doesn't thrash or drop events.
+- **FR-5.3** Retry split into **transient** (timeout 408/504, 5xx,
+  session-temporarily-unavailable) — retried with bounded backoff — vs
+  **persistent** (404 invalid clientId, 401 bad API key, 404 no connected
+  Foundry clients) — **no retry**, surfaced immediately with remediation. (A
+  wrong clientId 404s forever; retrying only delays the error.)
+- **FR-5.4** Every auto-sync op (push/skip/error/conflict) logged to the
+  activity panel with time, note, status, message; panel capped at the **last
+  200 events**, scrollable for older.
+- **FR-5.5** Inflight dedup + the shared per-uuid lock (FR-3.1) verified under
+  burst — no dropped events, no duplicate pushes, no cross-direction
+  oscillation.
+- **FR-5.6** **Before any auto or manual push to Foundry**, the prior
+  Foundry-side entry is `/get`-fetched and cached locally to
+  `foundry-backups/<uuid>/<iso>.json`; the last N per uuid are retained
+  (configurable). (This `/get` is the same one FR-1.4 reuses — no extra
+  round-trip.)
+- **FR-5.7** A **"Revert last push"** dashboard action restores the most
+  recent cached Foundry state for a note (writes it back via `/update`).
+- **FR-5.8** All auto-sync ops additionally append to a persistent, rotated
+  log file on disk (`logs/sync-<date>.log`) — survives restart, for support.
+- **FR-5.9** A **"Copy diagnostics"** dashboard action bundles recent log tail,
+  current config (secrets redacted), parity counts, and relay/clientId status
+  into a single redacted blob for support.
+
+### F6 — Onboarding & config (given operator prerequisites)
+
+- **FR-6.1** If `RELAY_CLIENT_ID` is unset/empty, the dashboard surfaces a
+  clear "no clientId configured" state with guidance — not a silent 404 at push
+  time.
+- **FR-6.2** If no Foundry client is connected to the relay (`activeClients =
+  0`), the dashboard surfaces "Foundry not connected" and disables
+  enable-auto-sync until resolved; re-checked on a cadence.
+- **FR-6.3** The dashboard can list connected relay clients (relay `/search`
+  with no clientId returns the client list on >1, or "No connected clients" on
+  0) so the DM can pick/copy a valid `clientId` from the UI. When **exactly
+  one** client is connected, the relay auto-resolves — the dashboard treats
+  that as "clientId auto-resolved, no pick needed" rather than showing an empty
+  list.
+
+### F7 — Security & access control
+
+- **FR-7.1** Dashboard authenticates by default (token or password set via env
+  or a first-run prompt); unauthenticated requests get 401, not the UI.
+- **FR-7.2** Default bind changes to `127.0.0.1`; `0.0.0.0` requires explicit
+  opt-in **and** an auth token set — the server refuses to start on `0.0.0.0`
+  without auth.
+- **FR-7.3** Secrets (`RELAY_API_KEY`, `RELAY_PASSWORD`) are never rendered to
+  the browser; the dashboard shows only masked presence/absence.
+- **FR-7.4** POST mutation endpoints require a CSRF token or same-origin
+  check.
+
+### §5a — Error contracts
+
+Every error row includes a one-line "what to do" string, not just a status.
+
+| Failure mode | Detection | Retry? | User message | Remediation |
+|---|---|---|---|---|
+| Relay unreachable | network error / connect refused | transient (backoff) | "Can't reach the relay at <url>." | Check relay container is up; check network. |
+| Relay 401 | HTTP 401 | **no** | "Relay rejected the API key." | Re-create `RELAY_API_KEY` (operator gate 2). |
+| clientId invalid/empty | 404 "Invalid client ID" | **no** | "The relay clientId is wrong or empty." | Pick a valid clientId from the client list (FR-6.3). |
+| No connected Foundry client | 404 "No connected Foundry clients found" | **no** | "Foundry isn't connected to the relay." | Start the headless session (operator gate 3); re-check runs automatically. |
+| Session idle-reaped | was connected, now 404 | transient (re-check) | "The Foundry session dropped." | Restart the headless session; dashboard re-checks. |
+| Hash mismatch (both diverged) | F-hash ≠ ccHash AND O-hash ≠ contentHash | n/a (route to F3) | "Both sides changed since last sync — conflict." | Open the conflict row (FR-3.2). |
+| `/get` 404 on a known uuid | 404 for a previously-linked uuid | **no** | "Foundry entry <name> was deleted on the Foundry side." | Re-link or remove the orphaned note. |
+| Persistent 5xx after backoff | 5xx after retries exhausted | **no** (already retried) | "The relay keeps erroring on this note." | See diagnostics (FR-5.9); contact support. |
+
+## 5. Non-Functional Requirements
+
+- **NFR-1 — No-clobber safety.** No auto-sync operation may overwrite a side
+  that has changed since the last sync. Both-diverged → conflict, never
+  auto-overwrite. TOCTOU window closed by FR-1.10 (post-push re-verify). The
+  current O→F code violates this (pushes on Obsidian-body-diff only) — must be
+  fixed before/within delivery A.
+- **NFR-2 — Fail-safe.** If the relay cannot read the Foundry side, the
+  operation is skipped and surfaced (error-contracts table) — never a blind
+  push on Obsidian-side-only evidence.
+- **NFR-3 — Performance.** Debounce (700ms) + bounded concurrency (3) handle a
+  ~50-note prep burst without dropped events or relay thrash. **Operating
+  envelope:** validated against a vault of ≥N notes and ≥M JournalEntries
+  (N/M chosen above the author's own size — OQ-3). Default cadences: shallow
+  poll seconds-tens-of-seconds, deep poll minutes. Relay-load ceiling = a
+  documented max concurrent `/update` + `/get` budget; deep-poll concurrency
+  capped via `mapPool`.
+- **NFR-4 — Reliability.** Transient relay errors retried with backoff;
+  persistent errors surfaced within one tick (no retry on persistent — FR-5.3).
+- **NFR-5 — Observability.** Every operation is visible in the dashboard
+  activity panel and the vault status note; no silent skips or silent
+  overwrites. Status-note writes never produce a sync op. Operation history is
+  **persistent across restarts** (FR-5.8).
+- **NFR-6 — Onboardability (honest).** Given the operator prerequisites (§2),
+  a non-author DM can reach a connected live sync using the dashboard with no
+  shell command beyond those prerequisites — the dashboard detects and guides
+  every unmet gate.
+- **NFR-7 — Configurability.** Poll cadences, debounce, concurrency, status-note
+  path, backup retention, and auth token are env/config-driven with safe
+  defaults.
+- **NFR-8 — Backward compatibility.** Existing manual buttons, seed/sync/
+  rePull/import rows, dev/apply modes, and the CLI-only full LevelDB index all
+  keep working unchanged. Auto-sync is newly gated to apply mode (FR-1.9).
+- **NFR-9 — Security.** No unauthenticated mutation path; no secret egress to
+  the client; default bind localhost; TLS recommended when bound beyond
+  localhost.
+- **NFR-10 — Data integrity.** Foundry-side overwrites are always preceded by a
+  local backup of the pre-push Foundry state (FR-5.6); the dashboard exposes a
+  restore path (FR-5.7). This complements, not replaces, Foundry world backups.
+- **NFR-11 — Upgrades.** The `foundry:` block carries a `schema_version`; a
+  version bump that changes hashing or identity fields ships with an idempotent
+  migration (re-hash, re-baseline) run in a single pass at startup before
+  auto-sync is allowed to engage, with a dashboard migration banner. (Old notes
+  lacking `ccHash` would otherwise route to conflict on first sync after
+  upgrade.)
+
+## 6. Open Questions
+
+- **OQ-1** Beyond the three explicit conflict actions, do we also offer a
+  one-click "newest mtime wins" convenience? Default posture = manual only.
+- **OQ-2** Where the "not syncing" indicator lives during run-the-match —
+  **deferred**. Reopens when a custom Foundry module is explored.
+- **OQ-3** Concrete cadence numbers (shallow poll, deep poll) and the NFR-3
+  operating-envelope N/M — pick during delivery B with relay-load testing.
+- **OQ-4** **Resolved** — status note lives at `${VAULT}/.sync-status.md` with
+  a `foundry.sync_status: true` sentinel; exclusion by both path and sentinel
+  (FR-4.3/4.6).
+- **OQ-5** New Foundry entries: candidates only with a one-click import + plain
+  explanation (FR-2.5) — confirmed; no auto-import.
+- **OQ-6** **Resolved** — conflict diff is side-by-side + plain-language
+  summary; "mark resolved" renamed to "Accept both as-is (keep divergence)"
+  with a confirmation (FR-3.6/3.7/3.8).
+- **OQ-7** `foundry.ccHash` field naming (`ccHash` vs `cc_content_hash` vs
+  `foundryHash`) — cosmetic, decide during delivery for grep-ability/
+  consistency with `cc_uuid`/`cc_type`.
+
+## 7. Out of Scope / Future
+
+- **In-UI first-run onboarding wizard** performing the operator prerequisites
+  (relay bring-up, API-key acquisition, headless-session launch, rest-api
+  wiring) — future PRD; this PRD honestly scopes NFR-6 to operator-wired prereqs.
+- **Custom Foundry module** — indicators inside Foundry UI + relay replacement;
+  would reopen OQ-2.
+- **Syncing during run-the-match** — sync stays off by design in the live
+  session.
+- **Automatic semantic / 3-way content merge** — both-diverged is manual
+  resolution via buttons; no auto content-merge engine.
+- **Auto-sync of unlinked or unseeded notes** — seed/link first stays manual.
+- **Full LevelDB / docker-stop index in the dashboard** — stays CLI-only.
+- **Doc task:** update README's "Foundry is the source of truth" wording to
+  match the demoted source-of-truth model (§1) before launch — tracked here to
+  avoid spec/onboarding drift.
+
+## 8. Success Metrics
+
+- **SM-1** Zero auto-overwrite events on a side that changed since last sync,
+  across a 50-note prep burst. **Counter-metric:** conflict-rows-surfaced > 0
+  whenever both sides diverged (the guard is working).
+- **SM-2** One verified end-to-end live O→F push (delivery A acceptance gate).
+- **SM-3** F→O detects a Foundry rename within ≤2 shallow poll ticks; a content
+  change within ≤1 deep poll tick.
+- **SM-4** Status-note writes never produce a sync op (FR-4.3/NFR-5 test).
+- **SM-5** A non-author DM, given the operator prerequisites, clones the repo
+  and reaches a connected live sync via the dashboard with no shell command
+  beyond those prerequisites.
+- **SM-6** Zero unauthenticated mutation paths (security gate; NFR-9).
+
+## 9. Glossary
+
+- **cc_uuid** — Foundry Campaign Codex UUID stored in a note's `foundry:` block;
+  its presence means the note is **linked**.
+- **contentHash** — SHA-256 of the canonicalized Obsidian note **body** (the
+  O-side baseline; `src/normalize.ts`).
+- **ccHash** — *(new)* SHA-256 of the canonicalized Foundry-side representation
+  (HTML→markdown + name + folder; the F-side baseline). See FR-1.4.
+- **linked note** — a refined note with a `foundry.cc_uuid`.
+- **seeded** — a linked note that also carries a `foundry.contentHash`
+  baseline (auto-sync prerequisites: linked + seeded).
+- **refined vault dir** — the Obsidian vault subdirectory holding curated notes
+  the tool syncs.
+- **refined markdown** — the curated Obsidian markdown format the tool
+  converts to/from Foundry's campaign-codex HTML.
+- **import candidate** — a Foundry JournalEntry not yet present in the vault;
+  surfaced for one-click import (FR-2.5).
+- **cc-only entry** — a Foundry entry with no matching refined note (≡ import
+  candidate from the Foundry side).
+- **dev / apply mode** — dev = preview into `--out` mirror; apply = writes the
+  real vault + live Foundry. Auto-sync is apply-only (FR-1.9).
+- **activity panel** — the dashboard feed of auto-sync events (FR-5.4).
+- **parity** — vault and Foundry agree for a note (both-side hashes match
+  baselines).
+- **tick** — one evaluation of a sync op (O→F on save, or F→O on poll).
+- **shallow poll / deep poll** — F→O's two layers (FR-2.1 / FR-2.2).
+- **conflict row** — the dashboard UI for a both-diverged note (F3).
+- **operator prerequisites** — the five infrastructure gates the operator
+  wires once before the dashboard can reach live sync (§2).

+title: "Engineering-feasibility review — Live Relay Sync PRD"
+reviewer: Claude (engineering-feasibility pass)
+prd: docs/prds/prd-foundry-obsidian-sync-2026-06-22/prd.md
+date: 2026-06-22
+scope: "Stress-test PRD technical claims against the actual codebase + relay constraints."
+---
+
+# Engineering-feasibility review
+
+Verdict at the end. Findings tiered **BLOCKER / HIGH / MEDIUM / LOW** with file:line
+citations and a recommended fix for each.
+
+## What the code actually does today (baseline facts)
+
+- `contentHash(text)` hashes **only the canonicalized body** — wikilink-canonicalize +
+  whitespace-canonicalize, then SHA-256. It does **not** include the note name, the
+  folder path, or any frontmatter. (`src/normalize.ts:24`, `canonicalize` at
+  `src/normalize.ts:19`.)
+- The `foundry:` block has no `ccHash` field. `readFoundryBlock` returns whatever keys
+  are in the nested map (`src/frontmatter.ts:9`); `baselineFoundryBlock`
+  (`src/server.ts:289`) rewrites **only** `contentHash:` and `syncedAt:` lines. So the
+  Foundry-side baseline the PRD depends on does not exist yet — it is genuinely new.
+- `AutoSyncController.process()` (`src/server.ts:582`) reads the note, compares
+  `contentHash(body)` to `fb.contentHash`, and on a difference calls `pushNote` **with
+  no relay `/get` of its own**. `pushNote` does call `relay.getEntry(id)`
+  (`src/push.ts:142`) but **only to build the diff** (preserve ownership/pages/
+  existing image) — it never compares a Foundry-side hash to a baseline. So if the
+  Foundry side changed since the last sync, `pushNote` still PUTs `{ name,
+  "flags.campaign-codex": cc }` and **overwrites the Foundry-side edit silently**.
+  Clobber risk is **real, not theoretical**.
+- Relay `/get` returns the full doc: `{ data: { name, type, _id, uuid, folder, pages,
+  ownership, flags, ... } }` (`docs/relay-api.md:31-33`). `folder` is present on
+  `/get`.
+- Relay `/search` minified returns **only** `{ uuid, id, name, img, documentType }`
+  (`docs/relay-api.md:55-59`, mirrored in `src/relay/client.ts:19-25`,
+  `searchJournalEntries` at `src/relay/client.ts:97`). **No `folder`. No content. No
+  content hash. No mtime.** This is the load-bearing constraint for F2.
+- ADR 005 (`wiki/decisions/005-autosync-o-to-f-only.md`) already analyzed F→O polling
+  and rejected it on cost grounds: ~800 `/get` calls/min for a ~200-entry world at a
+  15s cadence. The PRD does not cite or reconcile with this ADR.
+
+---
+
+## BLOCKER
+
+### B1 — FR-2.1 / FR-2.2: `/search` minified has NO `folder`. Folder-move detection from the poll snapshot is impossible.
+
+**Claim (PRD FR-2.1):** "poll `relay /search` … build a current `{uuid →
+name/img/folder}` snapshot."
+
+**Claim (PRD FR-2.2):** "moved (folder change)" is detected by diffing the current
+snapshot against the last snapshot.
+
+**Reality:** `relay /search?minified=true` returns `{ uuid, id, name, img,
+documentType }` only (`docs/relay-api.md:55-59`, `src/relay/client.ts:19-25`,
+`src/relay/client.ts:97-105`). There is **no `folder` field** in the minified result.
+The PRD's own §2 admits "/search is minified with no content hash" but then FR-2.1
+quietly assumes `folder` is present — it is not. You cannot build a
+`{uuid → folder}` snapshot from `/search`, and you cannot detect folder moves by
+snapshot-diffing alone.
+
+**Impact:** FR-2.2's "moved (folder change)" detection and FR-3.5's "folder moves
+surface as changes/conflicts" are **not implementable as specified**. Folder moves
+would be invisible to the F→O poll entirely.
+
+**Fix:** Pick one and write it into the PRD:
+1. **Per-note `/get` on every poll** to read `folder` (and content). This is the only
+   way to detect moves from the relay at all, and it collapses F2 into "every poll =
+   `/get` per linked note" (see B2). Accept the cost explicitly and override ADR 005.
+2. **Drop folder-move detection from F2.** Foundry-side renames are detectable
+   (name is in `/search`); folder moves are not. State this as a known gap and route
+   moves to the next manual Sync / Re-pull. This is the cheaper path and is honest
+   about the relay's surface.
+3. Propose a relay change (non-goal per PRD §3) — not available for this PRD.
+
+Recommended: **option 2** for this PRD, with option 1 as an explicit opt-in
+"deep poll" mode. Either way FR-2.1 and FR-2.2 must be rewritten to drop `folder`
+from the `/search`-derived snapshot.
+
+---
+
+### B2 — FR-2.2: content-change detection requires a `/get` per linked note per poll. The PRD does not account for the load, and this directly contradicts ADR 005.
+
+**Claim (PRD FR-2.2):** "content-changed (detected via `/get` hash compare)."
+
+**Reality:** `/search` minified has no content and no content hash
+(`docs/relay-api.md:55-59`). The only way to detect a Foundry-side content edit is to
+`/get` the full entry and hash it. So "detect content changes" = " `/get` every
+linked note every poll cycle." For the ~200-entry world in ADR 005 at the PRD's
+"seconds" default cadence (FR-2.6, OQ-3), this is **thousands of `/get` calls/min**,
+all funneled through one headless Foundry WebSocket. ADR 005 rejected exactly this
+design at 15s/800-calls-min as "heavy and fragile."
+
+**Impact:** NFR-3 ("does not overload the relay or the host") is **unsatisfiable** at
+the cadence the PRD hints at, with the design the PRD specifies. The PRD cannot
+both (a) detect Foundry content changes automatically and (b) avoid per-note `/get`
+load. One has to give.
+
+**Fix:** Make the F→O design explicit and costed in the PRD:
+- **Default: shallow poll.** `/search` only → detect **renames + new + missing**
+  (all detectable from minified `/search`). Content changes and folder moves are
+  **not** auto-detected; they surface on the next manual Sync / Re-pull or on a
+  user-triggered "catch up now" deep sweep (FR-2.6 already has the trigger — promote
+  it to the only content-change path).
+- **Opt-in deep poll:** a `/get`-per-linked-note sweep, cadence in **minutes**, not
+  seconds, with a concurrency cap (the existing `mapPool` at `src/server.ts:317` is
+  the right primitive). State the call-rate budget in NFR-3.
+- Add a line to §6 acknowledging this supersedes ADR 005's "F→O stays manual"
+  conclusion **only for rename/new/missing**, not for content.
+
+Without this, F2 is not shippable as written.
+
+---
+
+## HIGH
+
+### H1 — FR-1.4 / NFR-1: the "Foundry-side hash over content + name + folder" is a brand-new function, not derivable from `contentHash`. The PRD under-specifies it.
+
+**Claim (PRD FR-1.4):** compute a Foundry-side hash over "content + name +
+folder_path" from the `/get` response and compare to a new `foundry.ccHash` baseline.
+
+**Reality:**
+- `contentHash` (`src/normalize.ts:24`) hashes **canonicalized Obsidian markdown
+  body only**. It cannot be reused for the Foundry side — the Foundry `/get` response
+  stores content inside `flags["campaign-codex"].data` (HTML per
+  `obsidianToFoundryJsonLive`), not as refined markdown. Hashing the raw HTML is
+  fragile (Foundry may round-trip HTML attributes/whitespace); hashing requires
+  either (a) a stable HTML canonicalizer or (b) converting `cc.data` HTML back to
+  refined markdown and reusing `contentHash` — which is a non-trivial round-trip
+  through `entryToObsidian`-style logic that the PRD does not mention.
+- `name` and `folder` are present on `/get` (`docs/relay-api.md:31-33`) and are
+  stable scalars — hashing those is trivial.
+- The hard part is **content**. The PRD says "content + name + folder_path" as if
+  it's obvious; it is not. The PRD needs to specify the exact Foundry-side hash
+  input: is it `cc.data` raw, canonicalized HTML, or re-converted markdown? Each
+  has different drift properties.
+
+**Impact:** If the Foundry-side hash is unstable (e.g. Foundry re-serializes HTML
+between pushes), the divergence guard false-positives every tick → every save becomes
+a conflict → the tool is unusable. This is the single most likely delivery failure.
+
+**Fix:** Add a subsection to FR-1.4 specifying the hash:
+- Input: `canonicalize(htmlToMarkdown(flags["campaign-codex"].data)) + "\n" + name +
+  "\n" + folder` — i.e. reuse the existing `contentHash` pipeline by converting the
+  Foundry HTML body back to refined markdown first (the inverse of
+  `obsidianToFoundryJsonLive`). This makes the Foundry-side hash and the Obsidian
+  body hash **directly comparable** (same canonical form), which also makes the 2×2
+  routing in F3 well-defined.
+- Specify the HTML→markdown conversion (linkedom is already a dep per the wiki;
+  confirm it round-trips stably). Add a unit test for hash stability across a
+  push→/get round-trip before shipping FR-1.4.
+
+Also: `baselineFoundryBlock` (`src/server.ts:289`) and `baselineNote`
+(`src/server.ts:307`) currently touch only `contentHash`/`syncedAt`. FR-1.7 requires
+baseline of **both** `contentHash` and `ccHash` — both functions need a `ccHash:`
+line added to the rewrite, and `frontmatter.ts`'s `readFoundryBlock` consumers need
+to read it. Call this out as a concrete code change in the PRD.
+
+---
+
+### H2 — FR-1.6 fail-safe: the PRD correctly identifies the gap, but the fix has a subtle hole — the `/get`-then-`/update` race window.
+
+**Confirmed:** current `process()` (`src/server.ts:582-617`) does **not** `/get` to
+compare a Foundry-side hash before pushing. It pushes on Obsidian-body-hash-diff
+only. `pushNote`'s internal `/get` (`src/push.ts:142`) builds the diff but does not
+gate the push. So NFR-1 is **violated today** — the PRD is right to call this out.
+
+**Subtle hole in the proposed fix:** even with FR-1.4's "`/get` then compare ccHash
+then push" sequence, there is a TOCTOU window between the `/get` (read F-side
+baseline) and the `/update` (write). If a Foundry edit lands in that window, the
+push still clobbers it. The window is small (one relay round-trip) but nonzero.
+
+**Impact:** Low probability, but it's the same class of bug the PRD is trying to
+eliminate. Worth a defensive measure.
+
+**Fix:** After `pushNote`'s `relay.updateEntry` succeeds, re-`/get` and verify the
+entry's content hash matches what we just wrote; if it diverges (concurrent edit
+landed mid-flight), surface a conflict row instead of baselining. Cheaper
+alternative: document the window as accepted residual risk in NFR-1. Either is
+fine; the PRD should pick one explicitly.
+
+---
+
+### H3 — F3 routing: the O→F `inflight` set and the F→O poll do not share a lock. Concurrent O-save + F-poll on the same note can double-write.
+
+**Reality:** `AutoSyncController.inflight` (`src/server.ts:463`, used at
+`src/server.ts:583`) is keyed by **relPath** and only guards the O→F watcher path.
+The proposed F→O poll is a separate loop with no shared lock. If an O-save and an
+F-poll fire on the same uuid in the same tick:
+- O→F sees O-changed, F-unchanged → pushes O→F.
+- F→O sees F-changed (from the just-pushed O content? or a real F edit?), O-unchanged
+  (pre-save snapshot) → pulls F→O.
+Result depends on timing and can oscillate or clobber.
+
+**Impact:** NFR-1 ("never clobber") can be violated under concurrent cross-direction
+activity on the same note. Prep bursts are exactly this pattern.
+
+**Fix:** Add a **per-uuid lock** shared between the watcher path and the poll path
+(not per-relPath). While a sync op is in flight for a uuid, the other direction
+queues/skips. Add to FR-3.1 / FR-5.5. Also: the debounce window
+(`src/server.ts:567`, 700ms) is O-side only; an F edit arriving during the debounce
+is invisible to the watcher. The `/get` at push time (FR-1.4) is what catches it —
+confirm FR-1.4 is evaluated **after** debounce drains, not on the raw save event.
+
+---
+
+## MEDIUM
+
+### M1 — FR-1.4: one extra `/get` per changed note is acceptable, but the PRD should state the cost and cap it.
+
+One additional `/get` per push (on top of the `/get` `pushNote` already does at
+`src/push.ts:142`) doubles relay reads per O→F op. At the existing concurrency=3
+(`src/server.ts:466`) and debounce=700ms (`src/server.ts:467`) this is fine for a
+prep burst. But **reuse the `/get` `pushNote` already makes** — don't do two `/get`s.
+The cleanest implementation is to have `pushNote` (or a new wrapper) compute the F
+hash from the `liveEntry` it already fetched, compare to `ccHash` baseline, and
+gate the `/update` on that. The PRD reads as if FR-1.4 adds a **separate** `/get`
+before the push — that would be wasteful. Clarify: "the `/get` that `pushNote`
+already performs is reused for the F-side hash compare; no extra round-trip."
+
+### M2 — FR-2.5 new-entry detection: feasible, but `img` is the only extra signal beyond name+uuid.
+
+`/search` minified gives `{uuid, id, name, img, documentType}`. For new Foundry
+JournalEntries, `name + uuid` is enough to surface as import candidates (the
+existing import row at `src/server.ts:182-187` and `importRow` already works off
+`row.entry`). **Feasible.** One caveat: the dashboard's `ccOnly` pool
+(`src/server.ts:154`) is built from the **LevelDB journal snapshot** via `indexAll`,
+not from live `/search`. So "new entries surface as import candidates" requires
+either (a) merging live `/search` results into the index's `ccOnly` pool, or (b) a
+separate "live new entries" list in the dashboard. The PRD doesn't specify which.
+Recommend (b) to avoid conflating the static LevelDB index with live relay state.
+Add to FR-2.5.
+
+### M3 — FR-1.7 dev-mode baseline landing: `baselineNote` writes via `targetPath` (mirror in dev, real vault in apply) — correct, but the F→O pull writes the **vault** file and must use the same path resolution.
+
+`resolveRefined` (`src/server.ts:85`) prefers the dev mirror if it's newer, else the
+real vault. The F→O pull (FR-2.3) writes into the vault; in dev mode it must write
+to the mirror (`targetPath(state, "refined", rel)`), not the real vault, or dev
+mode stops being a safe preview. The PRD says "Dev mode baselines land in the
+`--out` mirror" (FR-1.7) — good — but FR-2.3 doesn't repeat the constraint for the
+**pulled content**. Add it.
+
+### M4 — FR-4.3 `Sync Status.md` watcher exclusion: the watcher's exclusion list today is `.obsidian` + dotfiles only (`src/server.ts:561`, `src/server.ts:533`).
+
+`onChange` skips `.obsidian` and dotfiles (`src/server.ts:561`). A `Sync Status.md`
+at the vault root is **not** a dotfile and **not** in `.obsidian`, so the watcher
+will fire on every status-note write → auto-sync will try to push it (it has no
+`foundry.cc_uuid` → skipped at `src/server.ts:591`, but still generates noise and a
+`/get`-less skip). The PRD (OQ-4) flags the path as TBD but doesn't note that the
+exclusion must be **added to `onChange`** explicitly. Add a concrete code-change
+note to FR-4.3: extend the skip predicate at `src/server.ts:561` to include the
+status-note path.
+
+---
+
+## LOW
+
+### L1 — FR-6.3 client-list discovery: the relay returns the client list on `>1` connected clients with no clientId, and "No connected clients" on 0 (`docs/relay-api.md:13-14`). With exactly 1, the relay auto-resolves and returns the doc — **no client list is surfaced**. So FR-6.3's "list connected relay clients" works only when there are 0 or >1 clients. The single-client case (the most common during prep) returns no list. The PRD should note this: when exactly one client is connected, the dashboard should treat that as "clientId auto-resolved, no pick needed" rather than showing an empty list.
+
+### L2 — FR-5.3 retry on 404: a 404 from the relay is **not always** transient. `404 {"error":"No connected Foundry clients found"}` (`docs/relay-api.md:13`) is a **persistent** condition (Foundry down) — retrying with backoff just delays the error. The PRD's FR-5.3 lists "404 invalid client" as transient-retryable; distinguish "invalid clientId" (retryable after re-fetching the client list) from "no connected clients" (persistent, surface immediately). Update FR-5.3.
+
+### L3 — FR-1.2 / FR-1.3 skip semantics: `process()` skips on no `cc_uuid` or no `contentHash` (`src/server.ts:591-592`) and on body-hash-equal (`src/server.ts:594`). All three are correct and already implemented. The PRD's FR-1.2/1.3 matches the code. No change needed; noted for traceability.
+
+### L4 — `foundry.ccHash` naming: the existing `foundry:` block uses snake_case-ish `cc_uuid`, `cc_type`, `folder_path`, `contentHash` (mixed). `ccHash` is fine but consider `cc_content_hash` or `foundryHash` for grep-ability and consistency with `cc_uuid`/`cc_type`. Cosmetic; decide during delivery.
+
+---
+
+## Overall verdict
+
+**Conditional-go.** The PRD's O→F hardening (F1, FR-1.4–1.7) is feasible and the
+clobber-risk diagnosis is accurate, but the Foundry-side hash (H1) is under-specified
+and is the most likely thing to derail delivery. The F→O direction (F2) has **two
+blockers**: the PRD assumes `/search` returns `folder` (it does not — B1) and assumes
+content-change detection is cheap (it requires a `/get` per linked note per poll,
+which ADR 005 already rejected on cost grounds — B2). F2 as written is not
+shippable; it needs to be scoped down to "shallow poll: renames + new + missing" with
+content/folder changes routed to the manual trigger, or it needs an explicit,
+costed deep-poll mode in minutes not seconds.
+
+The two-baseline 2×2 routing (F3) is sound in principle but has a real cross-direction
+lock gap (H3) and a TOCTOU window (H2) that the PRD should address.
+
+Recommended pre-delivery edits to the PRD:
+1. Rewrite FR-2.1/2.2 to drop `folder` from the `/search` snapshot (B1) and split
+   shallow vs deep poll (B2).
+2. Specify the exact Foundry-side hash input and the HTML→markdown reuse (H1).
+3. Add a shared per-uuid lock to F3/FR-5.5 (H3) and decide on the TOCTOU fix (H2).
+4. Clarify that FR-1.4 **reuses** the `/get` `pushNote` already makes (M1).
+5. Note the watcher-exclusion code change for `Sync Status.md` (M4) and the
+   single-client blind spot in FR-6.3 (L1).
+
+Top findings: **B1** (folder not in `/search`), **B2** (content detection = per-note
+`/get` every poll, contradicts ADR 005), **H1** (Foundry-side hash under-specified),
+**H2** (TOCTOU after `/get`), **H3** (no shared cross-direction lock).

+
+# Launchability & Onboarding Adversarial Review
+
+**Verdict: NOT launchable as specified.** The PRD sets stakes = "public/launchable" and
+NFR-6 promises "clone → live sync using the dashboard + `/setup`, without editing shell
+commands," but the F6 feature set only closes two of roughly seven onboarding gates, and
+several launchable-grade concerns (dashboard auth, Foundry-side data integrity, error
+contracts, status-note feedback-loop safety, conflict UX comprehension) are unspecified,
+hand-waved to "design during delivery," or silently dropped. The PRD reads as a strong
+*author-hardening* PRD wearing a *launchable* label. Two blockers and four high-severity
+findings stand between this draft and a non-author DM actually succeeding.
+
+Cross-references in this review: PRD = `prd.md` in this dir; README =
+`/home/kaykayyali/docker/obsidian-foundry-sync/README.md`; env =
+`/home/kaykayyali/docker/obsidian-foundry-sync/.env.example`.
+
+---
+
+## BLOCKER
+
+### B1 — `/setup` is not a product surface; NFR-6 is unmet as written
+
+**Finding.** FR-6.4 ("The existing `/setup` skill covers env wiring; the dashboard
+reflects setup state and links into it") and NFR-6 ("A non-author user can get from
+clone → live sync using the dashboard + `/setup`, without editing shell commands")
+treat `/setup` as a product feature. It is not. `/setup` is a Claude Code skill — an
+authoring-time convenience available only to someone running Claude Code against this
+repo. A non-author DM who clones the repo has no `/setup`. README §"Quick start"
+confirms the real onboarding path is five shell steps: `cp .env.example .env`,
+`docker compose up -d relay`, browser signup to copy `RELAY_API_KEY`,
+`node scripts/start-relay-session.js`, and `./sync.sh refresh` + `./sync.sh ui`.
+
+The F6 FRs only cover *detection* of missing config (FR-6.1 clientId empty, FR-6.2 no
+connected client, FR-6.3 list clients). They do not cover *acquisition* of:
+
+1. The `RELAY_API_KEY` (requires bringing up the relay container + browser signup —
+   shell + browser, not dashboard).
+2. Starting the headless Foundry session (`scripts/start-relay-session.js` — shell).
+3. Pointing Foundry's rest-api module at the relay WebSocket URL (Foundry-side admin
+   config — cannot be driven from the dashboard at all).
+4. Bringing up the relay container itself (`docker compose up -d relay` — shell).
+5. Installing deps / starting the dashboard (`npm install`, `./sync.sh ui` — shell).
+
+FR-6.2 detects "Foundry not connected" but the dashboard cannot *start* the headless
+session that would connect it. So the DM is stuck at a red banner with no in-UI remedy.
+
+**Why it matters for launchable.** This is the single promise that defines "launchable"
+for this product, and it is the one the PRD most overstates. A non-author DM following
+the PRD literally cannot reach live sync without shell, and the PRD does not acknowledge
+the gap — it papers over it by referencing a tool the end user does not have.
+
+**Recommended fix.** Pick one of two honest paths and state it in §3 and F6:
+
+- **(a) Downscope NFR-6** to "clone → live sync using the dashboard, *given a running
+  relay + headless session + REST-API module wired by the operator*," and add a §2
+  "Operator prerequisites" block that enumerates the shell/Foundry steps the DM (or
+  their operator) must complete once. This matches reality and is still a real
+  improvement over today.
+- **(b) Actually build the in-UI onboarding** for the five gates above: a dashboard
+  "first run" wizard that brings up the relay container via a host-side helper, guides
+  API-key creation (deep-link to the relay's signup page, paste key into a form),
+  launches the headless session via a server endpoint (not a shell command the user
+  types), and shows step-by-step instructions for the Foundry-side rest-api module
+  wiring with a connectivity check. Then NFR-6 stands. This is substantially more
+  delivery work than F6 currently implies and must be sized as such.
+
+Either way, drop `/setup` from the FRs and NFR-6 — it is an author tool, not a product
+surface. If (b) is chosen, add FR-6.5..6.8 for the four remaining gates.
+
+---
+
+### B2 — Dashboard binds `0.0.0.0:7788` with no auth; security is absent from the PRD
+
+**Finding.** README §"Batch dashboard" confirms the dashboard "binds 0.0.0.0 by default
+so it's reachable on your tailnet at this VM's IP, port 7788; pass `--host 127.0.0.1` to
+restrict to localhost." The PRD has **no security section**. There is no FR or NFR for
+authentication, authorization, transport security, or access control on the dashboard.
+The dashboard can push to a live Foundry world (`/api/push`, `/api/push-all`), read and
+write the vault on disk, and presumably surfaces the relay API key in some form. With
+auto-sync (F1) the dashboard also drives automatic live writes to Foundry. An
+unauthenticated `0.0.0.0` listener that can overwrite a live Foundry world is a
+launchable-grade security hole.
+
+The PRD also does not discuss: storage of `RELAY_API_KEY` and `RELAY_PASSWORD` (plaintext
+in `.env` per env.example), whether the dashboard ever reflects secrets to the browser,
+CSRF on POST endpoints, or what happens when the dashboard is exposed on a tailnet/shared
+network.
+
+**Why it matters for launchable.** A launchable product that can clobber a live Foundry
+world over an open port with no auth is irresponsible to ship. "Bind localhost" is a
+mitigation the README mentions but the PRD never requires; the default is `0.0.0.0`.
+
+**Recommended fix.** Add a §5 NFR-9 — Security, and a F7 — Security & access control
+feature group, minimum:
+
+- **FR-7.1** Dashboard authenticates by default (token or password set via env or
+  first-run prompt); unauthenticated requests get 401, not the UI.
+- **FR-7.2** Default bind changes to `127.0.0.1`; `0.0.0.0` requires explicit opt-in
+  *and* an auth token set (refuse to start otherwise).
+- **FR-7.3** Secrets (`RELAY_API_KEY`, `RELAY_PASSWORD`) are never rendered to the
+  browser; the dashboard shows only masked presence/absence.
+- **FR-7.4** POST mutation endpoints require a CSRF token or same-origin check.
+- **NFR-9** No unauthenticated mutation path; no secret egress to the client; TLS
+  recommended when bound beyond localhost.
+
+---
+
+## HIGH
+
+### H1 — Error contracts are unspecified; "surface an error row" is not actionable for a non-author DM
+
+**Finding.** FR-1.6, FR-5.3, NFR-2, NFR-4 all reference "error rows" / "surfaced" but
+none specify the error *vocabulary*, *messages*, or *remediation guidance*. The relay
+returns at least four distinct failure modes that a non-author DM cannot distinguish
+from a raw status code: relay down (network), session down (relay up but no Foundry
+client), clientId invalid (relay up, client up, wrong/empty id), hash-mismatch (conflict,
+not an error), and transient 404/408/504 (retryable). FR-5.3 collapses these to
+"transient relay errors (404 invalid client, 408/504 timeout, 5xx)" — but "404 invalid
+client" is *not* transient (a wrong clientId will 404 forever), and "session down" is
+not in the retry list at all. The mapping from relay response → user-facing message →
+recommended action is absent.
+
+**Why it matters for launchable.** NFR-5 promises "no silent skips," but a red row that
+says `Relay 404` is silent in the sense that matters: the DM does not know whether to
+fix `.env`, restart the headless session, or pick a different clientId. The author can
+debug from a status code; a non-author DM cannot.
+
+**Recommended fix.** Add a §5a "Error contracts" table mapping each failure mode to:
+(a) detection signal, (b) retry-or-not, (c) the exact user-facing message, (d) the
+remediation hint shown. Minimum rows: relay unreachable, relay 401 (bad API key),
+clientId invalid/empty, no connected Foundry client, session idle-reaped, hash mismatch
+(route to F3, not error),Foundry-side /get 404 on a known uuid (deleted on Foundry),
+and persistent 5xx after backoff. Specify that error rows include a one-line "what to
+do" string, not just a status. Split FR-5.3's retry list into *transient* (timeout, 5xx,
+session-temporarily-unavailable) vs *persistent* (404 invalid client, 401 bad key) with
+no retry on persistent.
+
+### H2 — `Sync Status.md` exclusion is not airtight; feedback-loop risk is unaddressed
+
+**Finding.** FR-4.3 maintains `Sync Status.md` in the vault, "on a path excluded from
+the watcher, never synced to Foundry, updated each tick." OQ-4 defers the path/exclusion
+mechanism to delivery. The vault is what the watcher watches (FR-1.1). If the exclusion
+is path/filename-based and the DM renames or moves the note, or the tool's path config
+drifts, the watcher fires on every tick's status-note write → auto-sync attempts to push
+a `foundry:`-less note (skipped by FR-1.2, but it still churns the activity panel and
+wakes the pipeline) or, worse, a future version seeds it and a feedback loop starts.
+The PRD does not specify: the exclusion *mechanism* (glob? exact path? frontmatter flag?
+a dedicated subdir?), what guarantees it across renames, whether the F→O poll also skips
+it (FR-2.x doesn't mention it), and what happens on a name collision with a real note.
+
+**Why it matters for launchable.** A status note that triggers sync is a self-inflicted
+loop that a non-author DM will not diagnose. "Excluded" stated as a requirement without
+a mechanism is a bug waiting to ship.
+
+**Recommended fix.** Promote OQ-4 to a specification: define the exclusion as a
+*dedicated, reserved path* (e.g. `${VAULT}/.sync-status.md` or a dot-prefixed file that
+FR-1.1's "skip dotfiles" rule already covers), AND a frontmatter sentinel (e.g.
+`foundry.sync_status: true`) that both the O→F watcher and the F→O poll check and skip
+on, so the exclusion holds even if the path changes. Add FR-4.6: "The status note is
+excluded from both O→F watch and F→O poll by *both* a path rule and a content sentinel;
+a status note that loses its sentinel is treated as user error and surfaced, not
+synced." Add an explicit test to NFR-5: status-note writes never produce a sync op.
+
+### H3 — Conflict UX is unspecified; "mark resolved (no change)" is a data-loss footgun for a non-author DM
+
+**Finding.** F3 routes both-diverged to a conflict row with "push vault → Foundry",
+"pull Foundry → vault", "mark resolved (no change)" (FR-3.3). OQ-6 defers diff format
+to delivery. Two problems:
+
+1. **Diff format is unspecified.** "Summarizing both versions and highlighting the diff"
+   (FR-3.2) could be a unified diff, a side-by-side, or a condensed summary — three very
+   different UX outcomes for a non-author DM staring at a conflict.
+2. **"Mark resolved (no change)" is genuinely ambiguous.** Its actual semantic (per
+   FR-3.1 + the no-clobber rule) is presumably "accept the current diverged state as the
+   new parity baseline without transferring content in either direction" — i.e. *both*
+   sides keep their diverged content and both hashes re-baseline to current values. A
+   DM reading "mark resolved (no change)" will reasonably think "do nothing, come back
+   later" or "keep both" — and may click it expecting safety, then discover later that
+   the two sides now permanently disagree and neither has the other's edits. There is no
+   FR specifying what "mark resolved" actually does to the baselines, whether the
+   divergence is preserved or collapsed, or what the DM is told just happened.
+
+**Why it matters for launchable.** This is the one screen where the DM makes an
+irreversible content decision. For the author it is obvious; for a non-author DM it is
+the screen most likely to lose work. "Design during delivery" is not a launchable
+specification for the highest-stakes UX in the product.
+
+**Recommended fix.** Resolve OQ-6 in the PRD, not in delivery. Specify:
+
+- **FR-3.6** Conflict diff format: side-by-side with a one-line plain-language summary
+  ("Vault adds 3 paragraphs about X; Foundry renamed to Y and changed folder to Z"),
+  not a raw unified diff.
+- **FR-3.7** "Mark resolved" is renamed to an explicit label — e.g. "Accept both as-is
+  (keep divergence)" — with a confirmation dialog that states in plain text: "The vault
+  and Foundry will keep their current versions. They will be treated as in-sync from
+  now on. Neither side's changes will be copied to the other."
+- **FR-3.8** Each conflict action states, before commit, what it will do to each side
+  and to the baselines (one-line preview). No irreversible action without a confirm.
+- **FR-3.9** A resolved conflict produces a visible activity-panel entry stating which
+  side won and that the other side's edits were *not* transferred.
+
+### H4 — Foundry-side data integrity has no backup/recovery story; auto-sync writes live with no Foundry-side undo
+
+**Finding.** FR-1.8 states "Auto-sync always applies live (dry-run not honored)." Manual
+`--apply` mode writes a timestamped `.bak-<iso>` of vault files it overwrites (README
+§"Modes"). But push to Foundry goes through the relay `/update`, which overwrites the
+live Foundry entry — there is no Foundry-side `.bak`, no undo, no rollback specified.
+For a non-author DM who auto-syncs a bad edit (or hits a bug, or a hash race), the
+Foundry world is the side with no recovery path. The PRD has no §"Data integrity" or
+backups section. The vault side has `.bak`; the Foundry side has nothing.
+
+**Why it matters for launchable.** A launchable sync tool that can overwrite a live
+Foundry world automatically, with no specified recovery path on the overwritten side,
+is a data-loss hazard. The author can restore from a world backup; a non-author DM may
+not have one scheduled.
+
+**Recommended fix.** Add a §5 NFR-10 — Data integrity, minimum:
+
+- **FR-5.6** Before any auto or manual push to Foundry, the prior Foundry-side content
+  is fetched and cached locally (a `foundry-backups/<uuid>/<iso>.json` dir) so a bad
+  push can be reversed from the dashboard. Specify retention (e.g. last N per uuid).
+- **FR-5.7** A "Revert last push" action exists for the most recent push per note.
+- **NFR-10** Foundry-side overwrites are always preceded by a local backup of the
+  pre-push Foundry state; the dashboard exposes a restore path.
+- Document in §2 that Foundry-side world backups (Foundry's own backup feature) remain
+  the DM's responsibility and are recommended before enabling auto-sync.
+
+---
+
+## MEDIUM
+
+### M1 — Performance NFR is sized to the author's vault, not real-world vaults
+
+**Finding.** NFR-3 bounds the burst target at "~50-note prep burst" with no stated basis.
+FR-2.1 polls `/search` for all `JournalEntry` minified on every tick — on a large world
+(hundreds or thousands of JournalEntries) this is a full scan per poll. No vault-size
+assumption is stated, no relay-load ceiling, no concurrency default numbers (FR-5.2
+"defaults tuned for prep" — what numbers?). The `RELAY_URL=http://localhost:3010`
+topology in `.env.example` reflects the author's all-on-one-host setup; the PRD does
+not acknowledge that a DM with remote Foundry has higher latency and a different
+retry/backoff profile.
+
+**Recommended fix.** State the operating envelope in NFR-3: tested vault size range,
+JournalEntry count range the poll is validated against, default poll cadence (resolve
+OQ-3 with a number + rationale), default debounce and max-concurrency numbers, and the
+relay-load ceiling (concurrent `/update` calls). Add NFR-3a: "F→O poll and O→F push
+paths are validated against a vault of at least N notes and M JournalEntries," with N
+and M chosen above the author's own size.
+
+### M2 — Auto-sync in dev vs apply mode is contradictory
+
+**Finding.** FR-1.7 says "Dev mode baselines land in the `--out` mirror; apply mode in
+the real vault with a `.bak`." FR-1.8 says "Auto-sync always applies live (dry-run not
+honored)." These interact unclearly: can auto-sync be enabled in dev mode at all? If
+yes, "applies live" to what — the `--out` mirror or the real vault? If auto-sync only
+makes sense in apply mode, say so and gate the toggle on `--apply`. If it can run in dev
+mode, define what "live" means there. A non-author DM who starts the dashboard in the
+default dev mode and flips on auto-sync will not know what is being written where.
+
+**Recommended fix.** Add FR-1.9: "Auto-sync requires apply mode; enabling it in dev mode
+is either blocked with an explanatory banner or explicitly writes to `--out` only (pick
+one and state it)." Reconcile FR-1.7/1.8 accordingly.
+
+### M3 — Status state single-source-of-truth has no persistence story across restart
+
+**Finding.** FR-4.5 says dashboard parity and the vault status note reflect "one
+underlying state (single source of truth for status)." The PRD doesn't say where that
+state lives. If it is in-memory in the server, a restart loses parity counts, conflict
+state (FR-3.4 "persists until resolved"), and last-sync time — but the vault status note
+persists. On restart, does the dashboard re-derive parity from a full re-scan, or does
+it show stale/empty until the next tick? Conflict persistence (FR-3.4) is especially
+load-bearing: a restart that drops conflict state could let a re-save auto-clear a known
+conflict, violating FR-3.4.
+
+**Recommended fix.** Specify the status store: either (a) a small persisted state file
+on disk (`sync-state.json`) that survives restart and is the single source the dashboard
+and status note both read from, or (b) re-derive on restart with an explicit "recomputing
+parity…" state. Add FR-3.4a: "Conflict state persists across server restarts, not just
+across ticks."
+
+### M4 — Versioning, updates, and frontmatter schema migration are unaddressed
+
+**Finding.** The PRD introduces a new frontmatter field `foundry.ccHash` (FR-1.4) and
+relies on existing `foundry.contentHash`/`cc_uuid`/`folder_path`. There is no schema
+version field on the `foundry:` block and no migration story. A non-author DM who
+updates the tool to a later version that changes hash algorithm or adds fields has no
+specified upgrade path — old baselines will mismatch and every note may route to
+conflict on first sync after upgrade. No §"Versioning & updates" section.
+
+**Recommended fix.** Add `foundry.schema_version` (or similar) to the identity block and
+an FR in F1/F5: on startup, notes with a missing/older schema version are migrated
+(re-hash, re-baseline) in a single pass before auto-sync is allowed to engage, with a
+dashboard migration banner. Add a §5 NFR-11 — Upgrades: "A version bump that changes
+hashing or identity fields ships with an idempotent migration; auto-sync stays disabled
+until migration completes."
+
+### M5 — Supportability: no persistent log / diagnostics export
+
+**Finding.** NFR-5 mandates observability via the activity panel and status note, but
+FR-5.4 says the panel is "capped and scrollable" — i.e. not persistent. A non-author DM
+who hits a problem and asks for help has no log file to share. There is no FR for a
+persistent log, a diagnostics export, or a "copy debug info" action. For a launchable
+product this is the difference between "I can help you" and "I can't see what happened."
+
+**Recommended fix.** Add FR-5.7 (renumber from H4's FR-5.7): "All auto-sync ops
+additionally append to a persistent, rotated log file on disk
+(`logs/sync-<date>.log`)." Add FR-5.8: "A 'Copy diagnostics' dashboard action bundles
+recent log tail, current config (secrets redacted), parity counts, and relay/clientId
+status into a single redacted blob for support." NFR-5a: "Operation history is
+persistent across restarts, not just visible in-session."
+
+---
+
+## LOW
+
+### L1 — Polling load on shared relays is a courtesy concern
+
+**Finding.** FR-2.1 polls `/search` on a cadence for every DM running the tool. If the
+relay is a shared instance (multiple DMs), uncoordinated polling multiplies. The PRD
+doesn't note this as a consideration or suggest a jittered/backoff poll.
+
+**Recommended fix.** Add jitter to the poll cadence and a note in §2 that on shared
+relays the cadence should be raised. Non-blocking.
+
+### L2 — New (cc-only) Foundry entries during prep: candidate vs auto-import is an open question with launchability impact
+
+**Finding.** OQ-5 leaves "auto-import new Foundry entries" open with current spec =
+candidates only. For a non-author DM, "import candidates" with no further guidance may
+mean a growing pile of unimported rows they don't know what to do with.
+
+**Recommended fix.** Resolve OQ-5 in the PRD: keep candidates-only (safe) but specify
+that the candidate row has a one-click "Import as new refined note" action with a clear
+explanation of what import does. The current import row exists per README; confirm it is
+comprehensible to a non-author DM.
+
+### L3 — "Foundry-wins" tie-breaker for both-diverged is deferred but conflict UX depends on it
+
+**Finding.** §1 confirms "Foundry is source of truth" is demoted to a tie-breaker for
+both-diverged, "to be decided: newest-wins, Foundry-wins, or manual merge." F3 then
+specifies manual resolution via buttons, which makes the tie-breaker moot *if* the DM
+always resolves manually. But the conflict row needs a *default ordering* (which side is
+shown on the left, which action is highlighted) and that ordering embeds a tie-breaker
+opinion. Leaving it undecided leaks into UX.
+
+**Recommended fix.** Pick a neutral default (e.g. vault on left, Foundry on right, no
+pre-highlighted action) so the undecided tie-breaker doesn't bias the DM. State it in F3.
+
+### L4 — README still describes Foundry as "source of truth"; PRD demotes it
+
+**Finding.** README L17 says "Foundry is the source of truth." The PRD §1 demotes that
+to a tie-breaker. For a launchable product the README is the onboarding doc and the PRD
+is the spec; a non-author DM reading both will be confused about which side wins.
+
+**Recommended fix.** Note in §6 / §"Out of Scope" that README wording will be updated to
+match the demoted-source-of-truth model before launch. Track as a doc task.

+## Overall recommendation
+
+**Do not mark this PRD ready for launchable delivery** until B1 and B2 are resolved
+(either by honest downscoping of NFR-6 or by committing to build the in-UI onboarding
+and auth) and H1–H4 are specified concretely enough to implement against. As a
+*hardening* PRD for the single author it is solid; as a *launchable* PRD it currently
+treats onboarding, security, error contracts, status-loop safety, conflict UX, and
+Foundry-side data integrity as "design during delivery" — exactly the surfaces where a
+non-author DM falls off.

+# PRD Quality Review — Live Relay Sync — Auto-Sync & Bidirectional Hardening
+
+## Overall verdict
+
+This is a tightly-argued, capability-spec PRD that earns most of its length: the
+no-clobber thesis is crisp, the trade-offs are named with what was given up (not
+just what was chosen), and Non-Goals do real work. What's at risk is downstream
+extractability and thesis-validation: there is no Glossary and no Success Metrics
+section, so a story author will re-derive domain terms and the PRD has no
+machine-readable way to confirm the thesis landed. A stale "to be decided" in the
+Vision also drifts from a decision the FRs already made. None of this blocks a
+green-light; all of it is one editing pass away from closed.
+
+## Decision-readiness — strong
+
+Decisions are stated as decisions, not buried as considerations. The `[CONFIRMED]` /
+`[DEFERRED]` tags in §1 are honest — e.g. _"Foundry is source of truth" is demoted
+to a tie-breaker rule for the both-diverged conflict case"_ names both the choice
+and the demotion. Trade-offs name what was given up: FR-1.6 explicitly says _"do
+not fall back to an Obsidian-side-only check (that reintroduces clobber risk)"_ —
+the rejected path is on the page, not hidden. The Open Questions are actually open:
+OQ-1 carries a default posture (_"Default posture is manual"_), OQ-3/OQ-4/OQ-6 are
+genuinely delivery-time (_"pick during delivery B with relay-load testing"_), and
+OQ-2 is a real deferral with the reopening condition named (_"Reopens when a
+custom Foundry module is explored"_). The decision-log shows real tensions
+surfaced (the clobber gap in the current O→F code) rather than smoothed to neutral.
+
+### Findings
+- **medium** Stale "to be decided" in Vision contradicts the FRs (§1, _"to be
+  decided: newest-wins, Foundry-wins, or manual merge"_). FR-3.2 and FR-3.3
+  already specify manual resolution with three explicit actions (_"push vault →
+  Foundry", "pull Foundry → vault", "mark resolved"_); OQ-1 only asks whether to
+  add a newest-mtime convenience. The §1 phrasing reads as unresolved when the
+  PRD has in fact decided. *Fix:* rewrite the §1 parenthetical to
+  _"default = manual resolution (FR-3.2); a newest-mtime convenience is open
+  (OQ-1)"_.
+
+## Substance over theater — strong
+
+No personas, no User Journeys, no differentiation section — and that is correct
+for a single-operator brownfield capability spec (see Shape fit). The Vision is
+product-specific, not swappable: the prep / run-the-match duality, the
+_"always in lockstep while I work"_ feeling, and the _"sync deliberately paused,
+not silently absent"_ framing would not transfer to another tool. NFRs carry
+product-specific thresholds, not boilerplate: NFR-3 names a _"~50-note prep
+burst"_, NFR-4 _"within one tick"_, NFR-6 names the _"UI-only convention"_. No
+innovation theater, no persona theater. Nothing here reads like furniture.
+
+### Findings
+- (none)
+
+## Strategic coherence — adequate
+
+The thesis is stated and the features serve it. G1 (no-clobber bidirectional
+auto-sync for prep) is the thesis; F1+F2+F3 implement it directly. G4 (legible
+status) is the second arc; F4 serves it. G5/G6 (hardening/onboarding) are the
+launchable-stakes rigor that follows from the chosen stakes, not a bolt-on.
+Prioritization follows the thesis: delivery A (ship O→F *with the divergence
+guard*) is gated on the safety fix, not on "what's easy first."
+
+The gap is that there is **no Success Metrics section**. The rubric asks whether
+SMs validate the thesis and whether counter-metrics are named. G2 embeds one
+criterion (_"verify one end-to-end live push"_), but there is no consolidated set
+of operational metrics that would let a reviewer confirm the thesis — e.g.
+"zero silent clobbers across a 50-note prep burst", "F→O poll detects a Foundry
+rename within N ticks", "non-author user reaches live sync via dashboard + /setup
+without shell". For a public/launchable PRD, the absence is a coherence tell: the
+PRD argues the thesis but doesn't state how it would know it landed.
+
+### Findings
+- **medium** No Success Metrics section (whole PRD). The thesis is clear but
+  unmeasured; activity metrics are absent too. *Fix:* add an SM block with 3–5
+  operational metrics tied to G1/G2/G4/G6 (e.g. _SM-1: zero auto-overwrite
+  events on a side that changed since last sync, across a 50-note burst_;
+  _SM-2: one verified end-to-end live O→F push_; _SM-3: F→O detects a Foundry
+  rename/move within ≤2 poll ticks_; _SM-6: a non-author user clones, runs
+  /setup, and reaches a connected live sync with no shell command_). Name a
+  counter-metric for SM-1 (e.g. _conflict-rows-surfaced > 0 when both sides
+  diverged_).
+
+## Done-ness clarity — adequate
+
+Most FRs carry testable consequences. FR-1.4's hash-over-_content + name +
+folder_path_ is concrete and verifiable. FR-1.5's 2×2 routing is a truth table.
+FR-3.1 makes the routing explicit. FR-2.2 enumerates the change kinds
+(_renamed / moved / content-changed / missing / new_). G2's _"verify one
+end-to-end live push"_ is an acceptance gate for delivery A. NFR-1 is the hard
+contract (_"No auto-sync operation may overwrite a side that has changed since
+the last sync"_).
+
+The unforgiving part: a few FRs use adjectives where bounds belong. FR-5.2 says
+_"defaults tuned for prep so a burst of simultaneous saves doesn't thrash or drop
+events"_ — "thrash" is undefined and "tuned for prep" is an adjective, not a
+bound; NFR-3 supplies the ~50-note number but FR-5.2 doesn't reference it.
+FR-5.4's _"panel capped and scrollable"_ leaves the cap unspecified. These are
+the spots where an engineer writing stories will have to go back and ask "how
+many?"
+
+### Findings
+- **low** FR-5.2 "thrash" / "tuned for prep" — bound-less adjectives (§F5).
+  *Fix:* bind FR-5.2 to NFR-3's ~50-note burst and name concrete defaults
+  ranges (debounce window, max concurrency) or defer the numbers to a config
+  table with placeholders.
+- **low** FR-5.4 "panel capped" — cap value missing (§F5). *Fix:* state the cap
+  (e.g. _"last 200 events, scrollable for older"_).
+
+## Scope honesty — strong
+
+Non-Goals do real work and name what could be silently assumed: _"Not syncing"
+indicator rendered inside Foundry_ is explicitly deferred with the reason
+(_"Foundry UI is not a surface we control"_); _"Syncing during run-the-match"_
+is called out as a design decision, not an omission; _"Automatic semantic / 3-way
+content merge"_ is excluded so the conflict UI doesn't get over-built. The
+`[ASSUMPTION]` tag in §2 (_"The relay remains the live transport for this PRD;
+the custom Foundry module … is explicitly future work, not a dependency here"_)
+flags the key inference. Open-items density is moderate (6 OQs + 1 ASSUMPTION)
+against launchable stakes; every OQ carries a default or a named
+delivery-trigger, so the density is honest rather than a blocker.
+
+### Findings
+- **low** Implicit relay-load assumption not flagged (§F2 / NFR-3). FR-2.2
+  detects content-changed entries _"via /get hash compare"_, which implies one
+  /get per changed linked note per poll tick — a load assumption that
+  interacts with OQ-3's cadence. This is an inference the user didn't directly
+  confirm and should be tagged `[ASSUMPTION]`. *Fix:* add
+  _`[ASSUMPTION]` one relay /get per changed linked note per poll tick is
+  acceptable relay load at the chosen cadence (OQ-3)_ to §F2, and index it.
+
+## Downstream usability — adequate
+
+FR IDs are contiguous (FR-1.1 → FR-6.4), unique, and cross-references resolve
+(FR-5.1 → FR-1.1 ✓; OQ-5 → FR-2.5 ✓; NFR-1 → the divergence guard ✓). Brownfield
+references are accurate against the decision log and code memory
+(_AutoSyncController_, _pushNote_, _foundry.cc_uuid_, _foundry.contentHash_,
+_rest-api module_, _relay /search_ minified, _relay /get_). No floating UJs (no
+UJs at all — appropriate). Each section reads sensibly pulled out alone.
+
+The gap is the **missing Glossary**. The PRD uses a thick domain vocabulary —
+_cc_uuid_, _contentHash_, _ccHash_ (new field, introduced in FR-1.4), _linked
+note_, _seeded_, _refined vault dir_, _refined markdown_, _import candidate_,
+_dev/apply mode_, _activity panel_, _parity_, _cc-only entry_ — and these are
+defined only inline and inconsistently (FR-1.2 glosses _foundry.cc_uuid_ as
+"unlinked"; FR-1.4 defines _ccHash_ in passing). A story author source-extracting
+from this PRD will have to reassemble the term set, and drift risk is real
+(_ccHash_ vs _contentHash_ vs _cc_uuid_ are easy to confuse). For a PRD that
+feeds architecture and stories, this is the dimension that needs the most work.
+
+### Findings
+- **medium** No Glossary section (whole PRD). Domain nouns are inline-defined
+  and not consolidated; _ccHash_ is introduced mid-FR without a term-of-art
+  definition. *Fix:* add a Glossary section defining at minimum: _cc_uuid_,
+  _contentHash_, _ccHash_, _linked note_, _seeded_, _refined vault dir_,
+  _refined markdown_, _import candidate_, _cc-only entry_, _dev/apply mode_,
+  _activity panel_, _parity_, _tick_. Reference Glossary terms from the FRs
+  instead of re-defining inline.
+
+## Shape fit — strong
+
+The shape matches the product. This is a brownfield, single-operator (DM/world-
+builder) capability spec intended to go launchable — exactly the case the rubric
+flags as _"Internal tool, single-operator role → capability spec shape; UJs may
+be overhead; SMs may be operational."_ No personas, no UJs: correct, not a gap.
+Operational SMs would fit the shape but their absence (see Strategic coherence)
+is a coherence gap, not a shape mismatch. The PRD is neither over-formalized (no
+UJ theater for a one-operator tool) nor under-formalized (NFRs and error
+contracts are present at launchable rigor). Existing-code references are
+distinguished from new behavior (_"code-complete but uncommitted"_, _"new field,
+e.g. foundry.ccHash"_), which is what brownfield shape demands.
+
+### Findings
+- **low** Operational SMs would fit this shape and are absent (§5 / §SM). *Fix:*
+  see the Strategic-coherence finding — operational metrics (zero silent
+  clobbers, ticks-to-detect, onboard-without-shell) are the right SM shape for
+  this product and would close both dimensions at once.
+
+## Mechanical notes
+
+- **Glossary drift:** No glossary; _ccHash_ vs _contentHash_ vs _cc_uuid_ are
+  used close together and differ only in case/short suffix — high confusion
+  risk. _"cc-only entry"_ (FR-2.5) and _"import candidate"_ (FR-2.5) are used
+  as synonyms without being linked. _"refined vault dir"_ / _"refined markdown"_
+  appear without definition (FR-1.1, FR-2.3).
+- **ID continuity:** FR IDs contiguous and unique; cross-refs (FR-5.1→FR-1.1,
+  OQ-5→FR-2.5, NFR-1→the divergence guard) all resolve. No duplicates, no gaps.
+- **Assumptions Index roundtrip:** broken. One inline `[ASSUMPTION]` exists
+  (§2, relay-as-transport); no Assumptions Index at the end of the PRD. The
+  implicit relay-load assumption (Scope honesty finding) is not tagged at all.
+- **UJ persona linkage:** N/A — no UJs, no personas (appropriate for shape).
+- **Required sections for stakes:** Vision ✓, Problem & Context ✓, Goals &
+  Non-Goals ✓, FRs ✓, NFRs ✓, Open Questions ✓, Out of Scope ✓. **Missing:
+  Success Metrics, Glossary.** For public/launchable stakes, SMs are expected;
+  Glossary is expected for a PRD that feeds architecture + stories.

+// Foundry→Obsidian operations on the same entry. The lock is keyed by Foundry
+// uuid (the `foundry.cc_uuid` value, normalized to the `JournalEntry.<id>`
+// form used by `relay.getEntry`) PLUS a resource tag (`"push" | "pull" |
+// "baseline"`). The lock is per-uuid, NOT per-direction: while one direction is
+// in flight for a uuid the other direction queues or skips, eliminating
+// cross-direction clobber and TOCTOU races without two separate guard systems.
+//
+// Resolution of relPath→uuid happens OUTSIDE the lock (the watcher/debounce
+// keys on relPath; the uuid is resolved by reading the note's `foundry.cc_uuid`
+// frontmatter before `acquire` is called). For unlinked/un-keyed files a
+// namespaced pseudo-uuid `"relPath:" + relPath` is used so the unlinked tail
+// still gets per-file mutual exclusion (the F→O direction, which receives a
+// uuid from the relay, never hits this fallback).
+//
+// Fairness: a queued waiter (policy "queue") is woken FIFO on release, and a
+// fresh public `acquire` DEFERS when waiters are already queued for that uuid
+// (returns `acquired:false, deferred:true`) so an opportunistic skip-policy
+// caller (auto-sync) cannot jump the queue ahead of a waiting manual button.

+// prePushGuard) against a MOCKED relay (globalThis.fetch), so we can assert

+// from /get) to the note's foundry.ccHash baseline and aborts the PUT on drift.
+//
+// Cases:
+//   1. clean (live matches baseline) → guard proceeds → PUT fires.
+//   2. drift (Foundry-side edit between baseline and save) → guard aborts → NO PUT.
+//   3. legacy note (no foundry.ccHash) → guard proceeds → PUT fires (one-time migration).
+//   4. relay /get unreadable (missing campaign-codex data) → fail-safe abort → NO PUT.
+//
+// Runs with sync-state.json ABSENT (process never touches it) — proving E1b.1
+// has no E4 dependency. Live end-to-end (SM-2) stays gated on the operator's
+// headless session; this is the offline-testable guard logic.

+# content-hash
+
+`contentHash(body)` in `src/normalize.ts`. Hashes a note's BODY (frontmatter excluded) to a
+stable string, stored in the note's `foundry.contentHash` and the cc file's `cc_sync_hash`.
+
+## How it's used
+- **Drift detection** ([[index-recommend]]): `refinedChanged` = `foundry.contentHash` !=
+  `contentHash(body)` (vault newer than last baseline). `ccChanged` = `cc_sync_hash` !=
+  cc body hash.
+- **Idempotency guard** ([[autosync]]): a save only pushes if `contentHash(body) !=
+  foundry.contentHash`. After a push, `baselineNote` sets `foundry.contentHash =
+  contentHash(body)` → subsequent no-op saves skip.
+- **push-all**: only rows with `recommendation === "sync-cc"` (i.e. body hash drifted from
+  baseline) are pushed; each is baselined after.
+
+## Why it matters
+`pushNote` always PUTs. The hash is the ONLY thing preventing redundant pushes and the
+auto-sync feedback loop. It's the project's core sync primitive.
+
+## Notes / gotchas
+- It hashes the BODY only, so a frontmatter-only edit (e.g. the post-push baseline rewrite)
+  does NOT change the body hash → that's exactly why the baseline write is a no-op for the
+  watcher.

+# foundry-block
+
+The `foundry:` nested mapping in a refined note's YAML frontmatter ties the note to its
+Foundry journal entry. Fields: `cc_uuid` (e.g. `JournalEntry.<id>`), `cc_type`, `folder_path`,
+`contentHash`, `syncedAt`.
+
+## Helpers (src/frontmatter.ts)
+- `splitFrontmatter(md)` → `{fm, body}`.
+- `readFoundryBlock(fm)` → the `foundry:` mapping as `Record<string,string> | undefined`
+  (so `fb.cc_uuid`, `fb.contentHash` are available).
+- `buildBlock(entry, body, stamp)` → the block content for seeding (used by `seedRow`/`handleLink`).
+- `seedBlockContent(md, block)` → inject/refresh the block in a note.
+
+## In server.ts
+- `baselineFoundryBlock(md, newHash, newSyncedAt)` — text surgery that rewrites ONLY the
+  `contentHash` + `syncedAt` lines inside the `foundry:` block, leaving `cc_uuid`/`cc_type`/
+  `folder_path` and all curation untouched. Mirrors `scripts/resync.ts`.
+- `baselineNote(state, relPath, absPath)` — reads the note, computes `contentHash(body)`,
+  calls `baselineFoundryBlock`, writes via the mirror-aware `targetPath`. Returns true if it
+  wrote. Used by push-all and [[autosync]].
+
+## Notes / gotchas
+- Baseline text-surgery is line-based: it scans for `foundry:` then the indented `  ` lines
+  beneath it. A note without a `foundry:` block is returned unchanged (no baseline).

+`src/resolver.ts` — the `NameResolver` interface + `MapNameResolver` impl, plus
+`nameUuidIndexFromEntries`, `saveNameUuidIndex`, `loadNameUuidIndex`.
+
+## How it's built / cached
+- `refresh` ([[refresh-flow]]) calls `relay.searchJournalEntries()` (minified) →
+  `nameUuidIndexFromEntries([{name,uuid}…])` → saves `<out>/name-uuid.json`.
+- `pushNote` resolves links via: a preloaded `resolver` arg → else `loadNameUuidIndex(<out>/
+  name-uuid.json)` → else build via relay `/search` (and cache it).
+
+## Notes / gotchas
+- The map is keyed by entry NAME. Curated notes whose filename differs from the Foundry entry
+  name (e.g. "Angro Harn" vs "Angro Harn - Journal") still resolve because the cc payload
+  carries explicit UUID references, and the index's uuid-fallback matching handles filenames.
+- `name-uuid.json` is gitignored output (lives under `--out`).

+# ADR 001 — External Foundry
+
+## Context
+The live stack on the original host runs Foundry in its own compose (`~/docker/foundryvtt`,
+Traefik-fronted). For a shareable bundle, baking Foundry in is impractical (license, world
+data, secrets). The cloner already has Foundry somewhere.
+
+## Decision
+Foundry stays external. The cloner supplies `FOUNDRY_URL` (+ world, user, password). The
+compose provides only the [[threehats-relay | relay]] and the (host-run) dashboard.
+
+## Consequences
+- One fewer service to bundle/license.
+- The relay must be reachable from the Foundry host (the rest-api module connects OUT over
+  WebSocket). If Foundry is remote, expose the relay port (port-forward / tailnet / public domain).
+- The `/setup` skill collects `FOUNDRY_URL`/`FOUNDRY_WORLD`/`RELAY_USER`/`RELAY_PASSWORD` from
+  the user and points their rest-api module at the relay.

+# ADR 002 — Tool stays host-run
+
+## Context
+The tool opens the Foundry journal LevelDB (read-only) for the dashboard's full index, and
+`refresh --full-index` stops/starts a local Foundry container via `docker`. Both need host
+access. Containerizing it would require bind-mounting the LevelDB + docker socket — fragile.
+
+## Decision

+dashboard binds `0.0.0.0:7788` (reachable on the tailnet) via `./sync.sh ui`.
+
+## Consequences
+- Cloner needs Node on the host (the tool runs via `npx tsx`).
+- `.env` carries host-specific paths (`VAULT`, `JOURNAL`, `FOUNDRY_DATA_DIR`) — gitignored.
+- The `/setup` skill starts the dashboard on the host, not via compose.

+# ADR 003 — Relay for live ops; LevelDB only for full index
+
+## Context
+Foundry holds the journal LevelDB open with a write lock. Reading it live requires stopping
+Foundry (the docker-stop path). That's downtime — unacceptable for routine push/refresh.
+
+## Decision
+- **Push / push-all / refresh** use the [[relay-client | relay]] (`/get`, `/update`, `/search`).
+  Foundry keeps running; no LevelDB open, no Docker stop. `cp -r` of the live journal dir is
+  used for the dev dashboard's snapshot (works while locked — only opening it is blocked).
+- The **full LevelDB read** (full entry docs, not minified) is CLI-only: `refresh --full-index`
+  stops/starts a local Foundry container. The dashboard's `indexAll` uses the snapshot copy.
+
+## Consequences
+- Live sync is zero-downtime.
+- The dashboard index's `entry` is the SNAPSHOT (`db.byId`), so pull ops (`rePullRow`) reflect
+  the snapshot, not live Foundry edits. Live edits need a fresh snapshot or a future live-pull
+  path. See [[index-recommend]].
+- `/search` is minified (no content hash) → can't detect live content changes cheaply
+  ([[005-autosync-o-to-f-only]]).

+# ADR 004 — Dropped browser Obsidian + plugin
+
+## Context
+Phase 1 of the shareable bundle added `ghcr.io/sytone/obsidian-remote` (browser Obsidian via
+noVNC) bind-mounted to the vault, plus a `foundry-sync` Obsidian plugin auto-installed by an
+`obsidian-init` one-shot. In practice: the noVNC desktop was heavy/laggy, plugin loading hit
+Obsidian's restricted-mode trust prompt (uncertain whether a preseed would be honored), and the
+user already edits a real desktop-Obsidian vault on this host (`Land of Mardonar`).
+
+## Decision
+Removed entirely (2026-06-21):
+- `obsidian` + `obsidian-init` services deleted from `docker-compose.yml`.
+- `plugin/` directory and `scripts/obsidian-init.js` deleted.
+- `.env` / `.env.example` obsidian vars (`OBSIDIAN_*`, `DASHBOARD_URL`, `PUID/PGID/TZ`) removed.
+- README + `/setup` skill rewritten: relay + dashboard only; edit notes in your own Obsidian
+  desktop app pointed at `$VAULT`.
+
+## Consequences
+- Compose now bundles ONLY the relay (`docker compose config` → `relay` + `relay-gpu` profile).
+- The dashboard (:7788) is the sole UI — consistent with the user's hard rule: "if it's not in
+  the dashboard UI, it doesn't exist." Push/pull/sync + auto-sync cover what the plugin did.
+- The user edits the vault in their own Obsidian app; the dashboard reads/writes the same files.

+
+# ADR 005 — Auto-sync is Obsidian→Foundry only
+
+## Context
+The user wanted hands-off sync both ways. Two facts shaped feasibility:
+1. The relay has **no change-push / events stream**. `/search` is minified (`{uuid,id,name,img}`)
+   with **no content hash** — so a live Foundry content edit can't be detected from `/search`.
+2. Detecting a live Foundry edit needs a `/get` per matched entry per cycle and a diff. For a
+   ~200-entry world, a fast poll (~15s) is ~800 `/get` calls/min through the headless Foundry —
+   heavy and fragile. The index's drift detection compares LOCAL baselines + a stale snapshot,
+   not live Foundry ([[index-recommend]]).
+
+So "instantly from either direction" is impossible: Obsidian→Foundry can be instant (inotify on
+the host vault); Foundry→Obsidian cannot.
+
+## Decision
+Auto-sync ([[autosync]]) is **Obsidian→Foundry instant only**. Foundry→Obsidian stays manual
+via the dashboard's Sync / Re-pull buttons. The user was offered three scopes (both + 60s poll,
+O→F only, both + 15s poll) and chose O→F only.
+
+## Consequences
+- Solves the actual pain: saving a linked, seeded note pushes it to live Foundry within ~1s.
+- Foundry→Obsidian requires a manual button click. A future live-pull path (relay `/get` per
+  matched entry + `entryToObsidian` on a poll) is feasible but not built — cost scales with
+  matched-entry count.
+- The guard + `baselineNote` are what keep it loop-free ([[autosync-watch-loop]]).

+`/session-handshake`, `/start-session`), which it forwards to the module.
+
+## Why we depend on it
+Live push/refresh without stopping Foundry or touching the LevelDB write lock ([[003-relay-no-journal-db-no-docker-stop]]).
+
+## How we use it
+- Bundled in `docker-compose.yml` as the `relay` service (port 3010, sqlite, `ALLOW_HEADLESS`,
+  `shm_size 1g`; `relay-gpu` profile for `/dev/dri` passthrough).
+- API keys created via the relay's web signup (no env/CLI) → `RELAY_API_KEY`.
+- Headless session launched by `scripts/start-relay-session.js` (handshake → RSA-OAEP encrypt

+- [[relay-client]] wraps the endpoints we use.
+
+## Risk / lock-in

+
+Driven by [[autosync]] `AutoSyncController`, toggled from the dashboard's "Auto-sync" button.
+
+## Steps
+1. `fs.watch(refinedDir, {recursive:true})` (per-dir fallback) fires on a `.md` change.
+2. Filter: must end `.md`, not be a `.bak`, not under `.obsidian/`.
+3. Debounce 700ms per file (coalesce rapid saves).
+4. `process(relPath)`:
+   - read via `resolveRefined` (mirror-aware);
+   - **guard**: skip unless `foundry.cc_uuid` (linked) AND `foundry.contentHash` (seeded) AND
+     `contentHash(body) !== foundry.contentHash` (actually changed);
+   - else `pushNote({dryRun:false})` ([[push-flow]]) → `baselineNote`.
+5. Log to the 100-event ring buffer (`pushed` / `skipped` / `error`); UI polls `GET /api/autosync`.
+
+## Why no loop
+After a push, `baselineNote` sets `foundry.contentHash = contentHash(body)`. The watcher then
+fires on that baseline write too, but the guard reads `body hash == contentHash` → `skipped:
+unchanged`. So the baseline write is a no-op for the watcher. No feedback loop, no double-push.
+
+## Edge cases / failure modes
+- Unlinked note (no `cc_uuid`) → `skipped: not linked` (seed/link first).
+- Unseeded note (no `contentHash` baseline) → `skipped: not seeded`.
+- Relay down / no headless session → `pushNote` → `relay.getEntry` 404 → `error` logged (no
+  crash, no Foundry write); the note is NOT baselined, so it retries on the next real save.
+- New note created from scratch → no `foundry:` block → skipped (seed/link it manually first).

+2. Read each file's meta: refined → `foundry.contentHash` (storedHash), body hash, mtime;

+3. Match by **basename** (canonical); **uuid fallback** via `foundry.cc_uuid` for curated
+   notes whose filename differs.
+4. `entry = db.byId(ccId)` — from the LevelDB **snapshot**.
+5. `recommend(...)`: `seed` | `sync-cc` (vault newer) | `repull` (cc newer) | `conflict` |
+   `in-sync` | `import` | `review`.
+
+## Drift is LOCAL-baseline-based, not live
+- `refinedChanged` = `foundry.contentHash` != `contentHash(body)` — vault newer than the LAST
+  BASELINE (set by a prior push/sync). Not "newer than live Foundry."
+- `ccChanged` = `cc_sync_hash` != cc body hash — cc file newer than its baseline.
+- `entry` is the snapshot, so pull ops (`rePullRow`) reflect the snapshot, not live Foundry.
+
+## Implications
+- The index is a fast, local, offline drift signal — great for "what have I edited since I
+  last pushed?" It does NOT know about live Foundry edits someone else made.
+- Live Foundry edits are only surfaced via the relay push/refresh path. Detecting a live

+Obsidian → live Foundry. Driven by [[push]] `pushNote`, invoked from the dashboard's push /
+push-all buttons and from [[autosync]].
+
+## Steps
+1. Read the refined note; pre-process body `![[image]]` embeds → upload to Foundry's uploads
+   dir, rewrite to `![](servedPath)` (drop non-local). Frontmatter untouched.
+2. `readNoteFoundryMeta` → `foundry.cc_uuid` (required — else "run seed first") + portrait.
+3. Resolve the name↔uuid map (preloaded → `<out>/name-uuid.json` → build via `/search`).
+4. `relay.getEntry(cc_uuid)` — the LIVE entry (keeps ownership/folder/pages/existing image).
+5. Upload portrait if present (needs `FOUNDRY_DATA_DIR`/`WORLD`).
+6. `buildPushPayload` → minimal diff `{ name, "flags.campaign-codex": cc }` (dot-path merge
+   preserves sibling flags; no `_id`/`pages`/`ownership`).
+7. dryRun → return diff. Apply → back up live entry to `<out>/bak/<name>.<stamp>.json`, then
+   `relay.updateEntry(uuid, diff)`.
+8. (caller) `baselineNote` → set `foundry.contentHash = contentHash(body)` so a re-run skips.
+
+## Edge cases / failure modes

+# autosync
+
+`AutoSyncController` in `src/server.ts`. Toggled via the dashboard's "Auto-sync" button
+(`POST /api/autosync {enabled}`); status + activity log at `GET /api/autosync` (the UI polls
+every 2s while on). See [[005-autosync-o-to-f-only]] for why it's one-directional.
+
+## How it works
+1. `fs.watch(refinedDir, {recursive:true})` (per-dir fallback for older Node) → `onChange`.
+2. Filter to `*.md`, skip `.obsidian/` and `.bak`. Debounce 700ms per file.
+3. `process(relPath)`:
+   - read the note via `resolveRefined` (mirror-aware);
+   - **guard**: skip unless `foundry.cc_uuid` exists (linked), `foundry.contentHash` exists
+     (seeded), and `contentHash(body) !== foundry.contentHash` (actually changed);
+   - `pushNote` (live, `dryRun:false`) → `baselineNote` (rewrite `foundry.contentHash` to the
+     new body hash).
+4. Bounded concurrency (3), per-file in-flight mutex, 100-event ring buffer (`events`).
+
+## The guard is the loop/idempotency key
+`pushNote` always PUTs. The guard skips no-op saves (body hash == baseline). After a push,
+`baselineNote` sets the baseline to the new body hash, so the watcher's own baseline write
+(also a `.md` change) reads as unchanged → skipped. No feedback loop, no redundant push.
+
+## Mode behavior
+- **dev**: baseline lands in the `--out` mirror (consistent with dev semantics); the mirror
+  then wins `resolveRefined` until the real vault is edited again.
+- **apply**: baseline lands in the real vault (with `.bak`).
+- The push itself goes live via the relay regardless of mode.
+
+## Notes / gotchas
+- Needs the relay + a live headless session (`activeClients > 0`), or `pushNote` → `relay.getEntry`
+  404s ("Invalid client ID" / no connected clients) and logs an `error` (no crash, no Foundry write).
+- Verified 2026-06-22: no-op save → `skipped: unchanged`; scratch note with fake uuid + body
+  change → guard passed → push attempted → relay 404 → `error` logged. Real-push end-to-end
+  pending the dev headless session coming back up.

+# batch
+
+`src/batch.ts` — `indexAll`, `recommend`, and the row builders (`seedRow`, `syncRow`,
+`rePullRow`, `importRow`). See [[index-recommend]].
+
+## indexAll(db, ccDir, refinedDir, refinedOverlay?, ccOverlay?)
+Walks refined + cc dirs (with dev-mode overlays), reads each file's meta, matches by
+**basename** (canonical — the exporter names cc files by entry name), with **uuid fallback**
+for curated notes whose filename differs but are already linked by `foundry.cc_uuid`. Produces:
+`matched`, `ccOnly`, `refinedOnly`, `counts`, `byRecommendation`. In dev mode the server
+passes the `<out>/refined` + `<out>/cc` mirrors as overlays so dev writes are reflected.
+
+## recommend(params) → Recommendation
+```
+refined-only → review
+cc-only (entry?) → import : review
+matched-unlinked → review
+matched+linked, !seeded → seed
+!hasCc | !ccSynced → sync-cc
+refinedChanged && ccChanged → conflict
+refinedChanged → sync-cc        (vault newer → push)
+ccChanged → repull              (cc/foundry newer → pull)
+else → in-sync
+```
+`refinedChanged` = note's `foundry.contentHash` != note body hash (vault newer than last
+baseline). `ccChanged` = cc file's `cc_sync_hash` != cc body hash. **Both compare against
+LOCAL baselines, not live Foundry.**
+
+## Row builders
+- `seedRow` — inject/refresh the `foundry:` block from the journal entry (curation untouched).
+- `syncRow` — regenerate cc.md from the refined note AND refresh the refined `foundry:` block;
+  baselines both sides.
+- `rePullRow` — regenerate the refined body from Foundry (`entryToObsidian(row.entry, …)`),
+  preserving curated type/aliases/status tags. Uses the snapshot `row.entry`.
+- `importRow` — cc-only entry → new un-curated refined note under `refined/imported/<folder>/`.
+
+## Notes / gotchas
+- `row.entry` comes from `db.byId(ccId)` — the LevelDB **snapshot**, not live Foundry. So
+  pull ops reflect the snapshot; live Foundry edits need a fresh snapshot (docker-stop full
+  index) or a future live-pull path. See [[003-relay-no-journal-db-no-docker-stop]].

+# push
+
+`src/push.ts` — `pushNote(deps)` and the pure `buildPushPayload(md, noteName, liveEntry, resolver, imageOverride?)`.
+
+## pushNote flow (see [[push-flow]])
+1. Read the note; pre-process body `![[image]]` embeds (upload co-located files to Foundry's
+   uploads dir, rewrite to `![](servedPath)`, drop non-local). Frontmatter untouched.
+2. `readNoteFoundryMeta` → `foundry.cc_uuid` (throws if absent — "run seed first") + portrait.
+3. Resolve the name↔uuid map: preloaded `resolver`, else `<out>/name-uuid.json`, else build via
+   relay `/search`.
+4. `relay.getEntry(id)` — fetch the LIVE entry (preserves ownership/folder/pages/existing image).
+5. Portrait upload if the note has one (and `foundryDataDir`/`world` set).
+6. `buildPushPayload` → `obsidianToFoundryJsonLive` (full entry with `name` + `flags.campaign-codex`
+   overridden, links resolved) → minimal diff `{ name, "flags.campaign-codex": cc }` (dot-path merge
+   preserves sibling flags; never echoes `_id`/`pages`/`ownership`).
+7. `dryRun` → return diff. Apply → back up the live entry to `<out>/bak/<name>.<stamp>.json`
+   (reversible), then `relay.updateEntry(id, diff)`.
+
+## Critical: no internal idempotency
+`pushNote` ALWAYS PUTs (unless `dryRun`). It does NOT compare the note body to anything. The
+caller is responsible for gating: the dashboard's push-all and [[autosync]] call `baselineNote`
+afterward to set `foundry.contentHash = contentHash(body)` so a re-run skips unchanged notes.
+Without that, repeated pushes re-send the same diff.
+

+
+## Notes / gotchas
+- Image upload needs `FOUNDRY_DATA_DIR` + `FOUNDRY_WORLD`; without them, images are skipped and
+  existing ones kept. See [[foundry-uploads-convention]] (in the user's memory, not this wiki).
+- `skipImageUpload` is used for fast batch dry-run previews that shouldn't touch the Foundry data dir.

+# relay-client
+
+`src/relay/client.ts` — `RelayClient(cfg)` wraps the relay's pass-through REST API. See
+`docs/relay-api.md` for envelope shapes.
+
+## Methods
+| Method | Relay call | Returns |
+|---|---|---|
+| `getEntry(uuid)` | `GET /get?uuid=` | `data: <JournalEntry>` |
+| `updateEntry(uuid, diff)` | `PUT /update?uuid=` body `{data:<diff>}` | `entity: [<doc>]` |
+| `createEntry(entityType, data)` | `POST /create` | `{uuid, data}` |
+| `searchJournalEntries()` | `GET /search?filter=documentType:JournalEntry&minified=true` | `results: [{uuid,id,name,img}]` |
+
+## Mechanics
+- Base URL: no `/api` prefix. Auth: `x-api-key` header on every request.
+- **World selection**: `clientId` query param. Omit only when exactly one Foundry client is
+  connected to the key (relay auto-resolves); 0 → `404`, >1 → `400` listing clients.
+- The relay forwards to Foundry's rest-api module over WebSocket and returns the module's
+  response verbatim. Envelopes are per-endpoint (`data` / `entity` / `results`).
+- WS round-trip timeout ~10s → `408`/`504`.
+
+## Notes / gotchas
+- For `update`, send a minimal diff (dot-path `flags.campaign-codex`), never the full doc —
+  echoing `_id`/`pages`/`ownership` would clobber the live entry.
+- `/search` is **minified** (`{uuid,id,name,img}`) — no content hash. So you cannot detect a
+  Foundry content change from `/search` alone; you'd need `/get` per entry. This is why
+  Foundry→Obsidian auto-sync wasn't built ([[005-autosync-o-to-f-only]]).

+# server
+
+`src/server.ts` — `startServer(cfg)` builds the index once, serves `dashboard.html` at `/`
+and a JSON API under `/api/*`. The mode (`dev` | `apply`) is fixed at startup; the UI cannot
+escalate to apply unless the server was started with `--apply`.
+
+## Mode + mirror-aware reads
+- **dev**: writes land under `--out/<bucket>/<relPath>` (a mirror). `resolveRefined` /
+  `resolveCc` read the mirror only if it exists AND is at least as new (mtime) as the real
+  file — otherwise the real vault (edited in Obsidian) wins. This makes dev a true preview
+  that never masks live vault edits.
+- **apply**: `targetPath` writes the real refined/cc dir; `writeWithBackup` copies a
+  `.bak-<stamp>` first (reversible).
+- dry-run never writes; it collects `preview` entries.
+
+## Routes
+| Method | Path | Handler |
+|---|---|---|
+| GET | `/` | `dashboard.html` |
+| GET | `/api/index` | rebuild index, return `IndexResult` (rebuilt every request — hash-only, cheap) |
+| GET | `/api/status` | `{mode, refinedDir, ccDir, outDir}` |
+| GET | `/api/file?name=` | per-row detail + seed/sync/re-pull previews |
+| GET | `/api/entries` | Foundry journal entries (name+uuid+type) from the snapshot, for the Link picker |
+| POST | `/api/action` | `runAction` — seed/sync/repull/import + All variants |
+| POST | `/api/push` | [[push]] one note (live) |
+| POST | `/api/push-all` | push every vault-newer matched note (live), baseline each |
+| POST | `/api/link` | inject the `foundry:` identity block (link a refined-only note by uuid) |
+| POST | `/api/refresh` | rebuild `name-uuid.json` via relay `/search` |
+| GET/POST | `/api/autosync` | [[autosync]] status / toggle |
+
+## State
+`{ db, cfg, index, autosync }`. `index` is rebuilt on every `/api/index` and after mutating
+ops (push-all, link) so recommendations reflect current files.
