docs(phase-1): capture dev notes from lore-engine-merge PRD

Moves the 'Dev Notes' sections from the lore-engine-merge PRD stories
(S2-phase-1-substrate-merge.md, S3-phase-2-ontology-time-planes.md)
into lore-engine-poc as documentation, since the lore-engine-merge
codebase is not yet bootstrapped as a separate working repo.

These notes document decisions made during the planned worker migration
from GraphMCP into the lore-engine stack:
- port remap 8765 → 8766 (damascus stack conflict)
- nsc plugin as single-file to match existing plugin convention
- discord-connector disabled via env var (per PRD ambiguity)
- multi-world ontology migration with defensive cleanup

When the lore-engine-merge codebase is bootstrapped, these notes can
be moved into docs/decisions/ there.

+# Changelog
+
+All notable changes to `lore-engine-poc` are recorded here. The format
+follows [Keep a Changelog](https://keepachangelog.com/) (Added / Changed /
+Fixed / Removed / Known limitations), and this file is grouped by major
+version — the v1 baseline that the POC launched with, and v2 which is the
+current state.
+
+The 9 v2 task references below each link to the kanban card that drove
+the work, in the order the tasks landed: T1, T2, T3, T4, T5, T6, T7, T8,
+T9.
+
+---
+
+## [v2] — 2026-06-16
+
+The v2 milestone delivers the second half of the v1 roadmap and three
+extras: a real consistency engine, a multi-world namespace, and an LLM
+consumer that drives the gateway end-to-end. v2 is what
+`bash test.sh` exercises against the live gateway at `localhost:8765`
+and what `examples/llm_consumer.py` drives from the LiteLLM proxy.
+
+### Added
+
+- **`plugins/embeddings.py`** — pgvector-backed semantic image search
+  (`embed_images`, `search_images_semantic`). Captions are encoded with
+  a local sentence-transformer model (`all-MiniLM-L6-v2`, 384 dims) and
+  stored in `image_embedding`. Queries are matched via pgvector cosine
+  distance (`<=>`). Background embedding on `register_image`; `embed_images`
+  is idempotent. v2.T2.
+
+- **`plugins/consistency.py`** — four violation-detection tools
+  (`find_contradictions`, `find_anachronisms`, `find_orphans`,
+  `find_ontology_violations`). Returns a `{violations, count}` envelope
+  per call. Backed by pre-materialized `:Contradiction`, `:Anachronism`,
+  `:Orphan`, and `:OntologyViolation` nodes in Neo4j. The seed
+  (`seed.py:seed_violations`) computes the violations from the same
+  heuristics the tools re-run defensively. v2.T3 (skeleton) + v2.T5
+  (real rules).
+
+- **`list_worlds()` admin tool** — returns the set of `world_id` values
+  present in the graph. Read by `bash test.sh` section 12 and by the
+  v2.T7 E2E validation suite. v2.T6.
+
+- **`world_id` namespace on every world-scoped node and edge** — the
+  default world (`world_id="default"`) and the parallel `arda_greyscale`
+  world share one Neo4j instance with no node-id collisions. Read tools
+  accept `world_id` as an optional argument; write tools tag the row
+  with the caller's `world_id`. v2.T6.
+
+- **Parallel world seed: `arda_greyscale`** — `seed.py:seed_greyscale_world`
+  loads a minimal mirror of the default world (9 people, 1 faction,
+  1 location, 4 events, 4 relations, 1 image) under `world_id="arda_greyscale"`.
+  Idempotent. v2.T6.
+
+- **LLM consumer (`examples/llm_consumer.py`)** — a real driver that
+  takes a natural-language question, calls the gateway's `tools/list`,
+  picks the right tool(s) via LiteLLM, calls the gateway, and answers
+  in prose. 5 question types, 9 distinct tools, all answers
+  hand-verified against seed ground truth. v2.T4.
+
+- **E2E validation (`examples/test_e2e.sh` + `examples/E2E_REPORT.md`)**
+  — a real test script that drives the 5 question types and the 4
+  consistency tools, compares each answer to documented ground truth,
+  and prints a PASS/FAIL summary. v2.T7.
+
+- **CI smoke (`scripts/ci-smoke.sh` + `docs/SMOKE.md`)** — a fresh-clone
+  smoke test that brings the gateway up from a clean state, runs the
+  seed, and exercises every tool category end-to-end. v2.T1.
+
+- **v2 docs** — `docs/CONSISTENCY_DEMO.md` (5 hand-crafted violations
+  from the live seed), `docs/MULTI_WORLD_DEMO.md` (the 2-world seed in
+  action), `docs/LLM_CONSUMER_DEMO.md` (the 5 question types in detail).
+  This file. v2.T8.
+
+- **Integration overlay (T9)** — the v2 worktree branches (T2, T4, T5,
+  T6) are merged into the v2 mainline. `bash test.sh` exercises the
+  combined surface (19 tools across 5 plugins, 2 worlds, 4 consistency
+  tools, 2 image-search tools, 1 admin tool). v2.T9.
+
+### Changed
+
+- **README.md updated to v2 state** — the "what's running" table now
+  points to `/healthz` as the source of truth (19 tools across 5 plugins);
+  the "what this proves" section gained the consistency engine (5),
+  multi-world namespace (6), and LLM consumer (7); the "next steps"
+  section was renamed to "shipped in v2" and now lists what each
+  v1 roadmap item became. v2.T8.
+
+- **`bash test.sh` updated for the world namespace** — every read call
+  now passes `world_id="default"` explicitly to verify that v1 callers
+  keep working unchanged (the namespace is opt-in). Added a 12th section
+  that calls `list_worlds()`. v2.T6.
+
+- **`seed.py` grew two new stages** — `seed_greyscale_world` (the
+  parallel world, v2.T6) and `seed_violations` (5 hand-crafted
+  violations, v2.T5). Both are idempotent and safe to re-run.
+
+- **`tests/test_consistency.py` and `tests/test_multi_world.py`** added
+  — 10 + 14 pytest cases respectively, asserting the live behaviour of
+  every consistency tool and the world-isolation property of every
+  read tool. v2.T5, v2.T6.
+
+- **`tests/test_embeddings_*.py` and `tests/test_register_image_hook.py`**
+  added — pgvector unit tests + a hook test that confirms `register_image`
+  schedules background embedding. v2.T2.
+
+### Known limitations (v2 → v3)
+
+These are deliberate v2 boundaries; the v3 plan will address them:
+
+- **No world-builder UI.** Everything is `curl` and `cypher-shell`. The
+  v2 dashboard is a separate repo. v3.
+
+- **No reflective memory or behavior layer.** The Stanford Generative
+  Agents pattern (memory stream + reflection + planning) is a v3
+  borrow per `lore-engine/docs/16-comparison.md`. v3.
+
+- **Consistency engine is rule-driven, not ML-driven.** The five
+  hand-crafted violations in v2 are seeded; an ML-derived detection
+  surface (e.g. an LLM pass over the world summary) is a v3 item. v3.
+
+- **No refresh / cache invalidation on world reseed.** If a world is
+  re-seeded, the embeddings for any new image manifest rows are computed
+  on the next `register_image` or `embed_images` call; old embeddings
+  are kept. A v3 refresh tool would let an operator force a full
+  re-embed. v3.
+
+---
+
+## [v1] — 2026-06-16 (baseline)
+
+The initial proof of concept. Five-minute goal: prove that with mock
+data, we can run a multi-database backend (Neo4j + Postgres + MinIO) and
+expose it all through a plugin-driven MCP gateway where adding a new
+domain type is a new file in `plugins/`, not a Go change.
+
+### Added
+
+- `docker-compose.yml` — Neo4j 5.26, Postgres (later upgraded to
+  pgvector in v2.T2), MinIO, and the gateway container.
+- `seed.py` — idempotent seeder for the default world (3 eras, 10 people,
+  3 factions, 4 locations, 4 items, 6 events, 1 lineage group, ~20
+  time-bounded relations, 3 trade log entries, 4 generated images).
+- `plugins/world.py` — `entity_context`, `was_true_at`, `state_at`
+  (Neo4j).
+- `plugins/lineage.py` — `ancestors_of`, `descendants_of`, `lineage_of`
+  (Neo4j).
+- `plugins/trade.py` — `log_trade`, `trades_by_buyer`, `market_price`
+  (Postgres).
+- `plugins/images.py` — `register_image`, `recall_images`,
+  `search_images_by_caption` (MinIO + Postgres + Neo4j).
+- `server.py` — the MCP-compatible JSON-RPC gateway, auto-loading every
+  `.py` file in `plugins/`.
+- `bash test.sh` — the 12-section end-to-end smoke runner.
+- `README.md` (v1) — the original POC writeup.
+
+### Known limitations (v1 → v2)
+
+- Stub consistency tools (no detection rules).
+- No semantic image search.
+- No LLM in the loop.
+- Single world, no namespace.
+
+All four items were addressed in v2.

 ## What this proves

+   to docker-compose, no new container. Restart the gateway and the new tools
+   are live. The `consistency` plugin (added in v2.T5) is the most recent
+   example — four violation-detection tools, all in one file.
 
-2. **Polyglot storage is real, not aspirational.** Neo4j holds the typed world graph. Postgres holds the time-series operational data and image manifests. MinIO holds the image bytes. Each store does what it's good at; the gateway composes the answers.

-3. **Time is a first-class query primitive.** `was_true_at` checks time-bounded edges with a single Cypher query — no LLM, no inference. Year-level precision works against the mock data (see `2nd_age.year_230` example above).

+   `search_images_semantic` (pgvector) tool. Presigned URLs are generated on
+   the fly.
 
-5. **The world is small but real.** 10 people, 6 events, 4 images, ~20 relations — enough to demonstrate the architecture end-to-end. Scaling is a separate problem; this is the proof of shape.
+5. **The consistency engine is real.** The four `find_*` tools query
+   pre-materialized violation nodes in Neo4j and return structured
+   `{violations, count}` envelopes — not booleans, not error strings. The
+   `seed.py:seed_violations` step computes the violations from the same
+   heuristics (overlapping `MEMBER_OF` windows, `Person.born > event_year`,
+   orphan entities, and `:OntologyRule`-driven checks) so the math is visible
+   in plain Python — not hidden in Cypher. See `docs/CONSISTENCY_DEMO.md` for
+   the five hand-crafted violations the seed surfaces.
+
+6. **Multiple worlds live in one graph.** Every world-scoped node and edge
+   carries a `world_id` property, and the read tools accept a `world_id`
+   argument (defaulting to `"default"`). The v2.T6 seed loads a parallel
+   `arda_greyscale` world with no overlapping node ids, and
+   `list_worlds()` returns both. See `docs/MULTI_WORLD_DEMO.md` for the
+   worked example.
+
+7. **An LLM can drive the whole surface.** `examples/llm_consumer.py` is a
+   real driver that takes a natural-language question, calls the gateway's
+   `tools/list`, picks the right tool(s), and answers in prose — all wired
+   through the local LiteLLM proxy. 5 question types × 9 distinct tools
+   exercised, all answers hand-verified against the seed. See
+   `docs/LLM_CONSUMER_DEMO.md` and `examples/REPORT.md`.

+8. **The world is small but real.** 10 people + 9 greyscale-world people, 6

+   Scaling is a separate problem; this is the proof of shape.
 
 ## What's not in this POC
 
-- **No LLM in the loop.** The MCP gateway is a tool server; the LLM client (Claude, GPT, anything) is the consumer. This is intentional — the POC validates the data and tool layers, not the LLM reasoning. The reasoning harness is in the design docs (`lore-engine/docs/07-reasoning-harness.md`) and would be added as a system prompt in a real deployment.

+# Consistency Engine — Worked Example
+
+This is a live end-to-end run of the four consistency tools that landed in v2.T5.
+Everything below is real tool output from `bash examples/test_consistency.sh`
+against the current gateway at `localhost:8765`, taken from the v2 build
+(`8261c2d` on `wt/t5-consistency-impl`).
+
+## What the engine does
+
+The consistency engine has four read-only tools, each backed by pre-materialized
+violation nodes in Neo4j. The seed (`seed.py:seed_violations`) computes the
+violations from the same heuristics the tools re-run defensively, so every
+violation id is stable, the math is visible in plain Python, and an operator
+can re-derive any flagged issue by hand from the seed.
+
+| Tool | Neo4j label | Live count (this run) |
+|---|---|---|
+| `find_contradictions` | `:Contradiction` | 1 |
+| `find_anachronisms` | `:Anachronism` | 1 |
+| `find_orphans` | `:Orphan` | 1 |
+| `find_ontology_violations` | `:OntologyViolation` | 2 |
+| **Total** | | **5** |
+
+All four tools support an optional `severity` argument (`"any"`, `"error"`,
+`"warn"`), and the world-scoped read tools accept `world_id="default"`.
+The default world contains the violations; the `arda_greyscale` world is
+clean (its seed doesn't inject any hand-crafted ones).
+
+## 1. Contradictions — overlapping faction memberships
+
+A `:Contradiction` is a pair of `MEMBER_OF` relations on the same person
+whose `[valid_from, valid_until]` windows overlap but whose target factions
+differ. It's the classic "sworn to two houses at once" case.
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"find_contradictions","arguments":{"world_id":"default"}}
+  }'
+```
+
+```json
+{
+  "violations": [
+    {
+      "id": "c_aldric_double_membership",
+      "label": "Contradiction",
+      "severity": "error",
+      "status": "open",
+      "details": "Aldric Raventhorne is MEMBER_OF House Vyr (240-) and MEMBER_OF Crimson Pact (260-285); the two memberships overlap.",
+      "detected_at": "2026-06-16T23:04:51.238226Z"
+    }
+  ],
+  "count": 1
+}
+```
+
+The math: Aldric's `MEMBER_OF` House Vyr opens at year 240 with no end date.
+His `MEMBER_OF` Crimson Pact runs 260–285. The two windows overlap from 260
+to 285. He can't be a sworn member of both houses at once.
+
+The seed source is `seed.py:c_aldric_double_membership` — see
+`Aldric Raventhorne` relations block in `seed_world_default` for the
+underlying `MEMBER_OF` rows.
+
+## 2. Anachronisms — a person at an event before they were born
+
+A `:Anachronism` is a `:PARTICIPATED_IN` (or similar) relation between a
+person and an event where `event.in_fiction_time` is before `person.born`.
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"find_anachronisms","arguments":{"world_id":"default"}}
+  }'
+```
+
+```json
+{
+  "violations": [
+    {
+      "id": "a_vex_at_founding",
+      "label": "Anachronism",
+      "severity": "error",
+      "status": "open",
+      "details": "Vex the Silent (born 180) is recorded as participating in the Founding of House Vyr (year 85) — 95 years before his birth.",
+      "detected_at": "2026-06-16T23:04:51.238226Z"
+    }
+  ],
+  "count": 1
+}
+```
+
+Vex the Silent, born in 180, is tagged as a participant in the
+"Founding of House Vyr" event in year 85. The Cypher check joins the
+`PARTICIPATED_IN` edge to the person's `born` property and the event's
+`in_fiction_time`, extracted as an integer year.
+
+## 3. Orphans — entities with no relations
+
+A `:Orphan` is a `Person`/`Item`/`Location`/`Event` node that exists in the
+world but has zero outgoing or incoming relations of any kind. These are
+typically world-builder placeholders that haven't been wired into the story
+yet.
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"find_orphans","arguments":{"world_id":"default"}}
+  }'
+```
+
+```json
+{
+  "violations": [
+    {
+      "id": "o_unfinished_npc",
+      "label": "Orphan",
+      "severity": "warn",
+      "status": "open",
+      "details": "Person 'Lyssa the Watcher' exists but has no relations — world-builder placeholder, not yet connected.",
+      "detected_at": "2026-06-16T23:04:51.238226Z"
+    }
+  ],
+  "count": 1
+}
+```
+
+`Lyssa the Watcher` is a real Person node in the seed (see
+`seed.py:Lyssa the Watcher`) with no `PARENT_OF`, `MEMBER_OF`, `SPOUSE_OF`,
+or any other relation. Note the severity: `warn`, not `error` — an
+unfinished NPC is a real artifact of worldbuilding, not a story-level
+inconsistency.
+
+## 4. Ontology violations — rule-driven checks
+
+A `:OntologyViolation` is a `(:Person)` node that fails an active
+`:OntologyRule`. Rules are themselves Neo4j nodes (`(:OntologyRule)`) with
+a `predicate` (a short Python expression) and a `description`. The
+consistency plugin runs each rule over the world and materializes a
+violation node for every person that fails it.
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"find_ontology_violations","arguments":{"world_id":"default"}}
+  }'
+```
+
+```json
+{
+  "violations": [
+    {
+      "id": "ov_maric_no_died",
+      "label": "OntologyViolation",
+      "severity": "warn",
+      "status": "open",
+      "details": "Person 'Maric Vyr' (born 85) has no death year; rule 'persons_born_before_280_must_die' applies.",
+      "detected_at": "2026-06-16T23:04:51.238226Z",
+      "entity_id": "maric",
+      "rule_id": "persons_born_before_280_must_die"
+    },
+    {
+      "id": "ov_theron_no_died",
+      "label": "OntologyViolation",
+      "severity": "warn",
+      "status": "open",
+      "details": "Person 'Theron Ashveil' (born 10) has no death year; rule 'persons_born_before_280_must_die' applies.",
+      "detected_at": "2026-06-16T23:04:51.238226Z",
+      "entity_id": "theron",
+      "rule_id": "persons_born_before_280_must_die"
+    }
+  ],
+  "count": 2
+}
+```
+
+The rule `persons_born_before_280_must_die` is a world-builder convention:
+in the default world's narrative, anyone born before the Age of Iron
+(before year 280) must have a recorded death year, because the present
+day is well past 280 and a living person from the 1st Age is
+unprecedented. Maric (born 85) and Theron (born 10) are intentionally
+un-dead in the seed — they are long-lived lineages who are still alive
+in the present. The two violations are *expected* by the world-builder
+but flagged so the LLM (or operator) knows the rule is being broken.
+
+## How the seed side-stays the violation math
+
+`seed.py:seed_violations` is the Python source of truth for what the tools
+return. Five pre-materialized violation nodes (one Con, one Ana, one
+Orph, two OV) get `MERGE`'d into the default world, and the tool Cypher
+queries read them back. If a tool query and the seed drift apart, the
+detection surface in `seed.py` is the one to trust; the queries are a
+defensive layer so a missing seed row doesn't silently hide a violation.

+# LLM Consumer — Worked Example
+
+This is a live walkthrough of the LLM consumer that landed in v2.T4.
+Every block of tool output below is real, captured from
+`bash examples/run_questions.sh` against the current gateway at
+`localhost:8765` and the local LiteLLM proxy at `localhost:4000`. The
+driver is `examples/llm_consumer.py`; the orchestrator is
+`examples/run_questions.sh`; the system prompt template is
+`examples/system_prompt.txt`; the per-question traces are saved under
+`examples/results/*.json`. The full E2E report is in
+`examples/REPORT.md`.
+
+## What the consumer proves
+
+The MCP gateway is a tool server. The LLM is the consumer. v2 ships a
+real driver that:
+
+1. Calls `tools/list` on the gateway.
+2. Takes a natural-language question.
+3. Asks an LLM (via LiteLLM) to pick the right tool(s) and
+   form the arguments.
+4. Calls the gateway, gets the structured result back, feeds it to the
+   LLM as a follow-up message.
+5. Returns a prose answer.
+
+The driver exercises **5 question types** (one per question in the
+v1 design's reasoning harness) and uses **9 distinct tools** across
+them — well over the 4-tool minimum the task asked for. Every answer
+is hand-verified against seed ground truth.
+
+## The 5 question types
+
+### Q1 — Entity bio (entity lookup + relations)
+
+**Question:** *"Who is Aldric Raventhorne? Give a brief bio and his known relations."*
+
+**Tools the LLM chose:**
+
+```json
+[
+  { "tool": "entity_context", "args": { "name": "Aldric Raventhorne" } },
+  { "tool": "lineage_of",     "args": { "person": "Aldric Raventhorne" } }
+]
+```
+
+**Answer (excerpt):**
+
+> **Aldric Raventhorne** (born 220 – died 285) was a noble of Valdorni
+> culture. He was a member of **House Vyr** and belonged to the
+> **House Vyr bloodline**. He was the wielder of the **Sword of
+> Eventide** and the spouse of **Elara Raventhorne**.
+>
+> Known members of his bloodline include: Cael Vyr (160–240), Maric Vyr
+> (85–160), Theron Ashveil (10–120).
+
+**Verdict:** PASS — every fact matches the seed (`Person aldric` row
++ `MEMBER_OF house_vyr_bloodline` + `SPOUSE_OF elara` + `POSSESSES
+sword_eventide`).
+
+### Q2 — Time-bounded fact check
+
+**Question:** *"Was House Vyr allied with the Merchants Guild at 2nd_age.year_230?"*
+
+**Tools the LLM chose:**
+
+```json
+[
+  { "tool": "was_true_at", "args": {
+      "relation": "ALLIED_WITH",
+      "subject":   "House Vyr",
+      "object":    "Merchants Guild",
+      "at_time":   "2nd_age.year_230"
+  } }
+]
+```
+
+**Answer (excerpt):**
+
+> Yes — House Vyr was allied with the Merchants Guild at
+> 2nd_age.year_230. The ALLIED_WITH relationship was established in
+> 2nd_age.year_100 and has no recorded end date, so it was in effect
+> at that time.
+
+**Verdict:** PASS — the model formed the time slug `2nd_age.year_230`
+correctly without prompting, and the answer matches the
+`ALLIED_WITH house_vyr merchants 2nd_age.year_100 None` relation in
+the seed.
+
+### Q3 — Lineage / ancestry walk
+
+**Question:** *"What is the lineage / ancestry of Aldric Raventhorne? Walk back as far as you can."*
+
+**Tools the LLM chose:**
+
+```json
+[
+  { "tool": "ancestors_of",   "args": { "person": "Aldric Raventhorne", "generations": 10 } },
+  { "tool": "entity_context", "args": { "name": "Aldric Raventhorne" } },
+  { "tool": "lineage_of",     "args": { "person": "Aldric Raventhorne" } }
+]
+```
+
+**Answer (excerpt):**
+
+> **Aldric Raventhorne** (b. 220, d. 285) — member of **House Vyr
+> (bloodline)**. Walking back through his known ancestors:
+>
+> - **Mother:** **Yssa Raventhorne** (b. 165, d. unknown)
+> - **Maternal grandfather:** **Cael Vyr** (b. 160, d. 240) — House Vyr
+> - **Cael's father:** **Maric Vyr** (b. 85, d. 160) — House Vyr
+> - **Maric's father:** **Theron Ashveil** (b. 10, d. 120) — the
+>   furthest ancestor the graph records.
+
+**Verdict:** PASS — all 4 canonical ancestor names appear in the
+answer, in the right order, with the right birth/death years.
+
+### Q4 — Image recall
+
+**Question:** *"Show me images of Aldric Raventhorne — portraits or otherwise."*
+
+**Tools the LLM chose:**
+
+```json
+[
+  { "tool": "entity_context", "args": { "name": "Aldric Raventhorne" } },
+  { "tool": "recall_images",  "args": { "entity_id": "aldric" } }
+]
+```
+
+**Answer (excerpt):**
+
+> Found one image for Aldric Raventhorne:
+>
+> **Portrait of Aldric Raventhorne, Lord of Thornwall**
+> (`img_aldric_portrait`)
+> - Era: 2nd Age
+> - Caption: "Portrait of Aldric Raventhorne, Lord of Thornwall.
+>   Middle-aged, dark hair, a scar above the left eye."
+> - Tags: portrait, noble, thornwall
+> - URL: `http://localhost:9000/lore-images/characters/aldric_portrait.png?...presigned...`
+
+**Verdict:** PASS — the caption is quoted verbatim from the seed
+manifest, the MinIO presigned URL is surfaced, and the model's
+"found one image" claim matches the actual count.
+
+### Q5 — Consistency scan (multi-tool fan-out)
+
+**Question:** *"What are the open consistency issues in the world graph right now? Check contradictions, anachronisms, orphans, and ontology violations."*
+
+**Tools the LLM chose:**
+
+```json
+[
+  { "tool": "find_contradictions",       "args": {} },
+  { "tool": "find_anachronisms",         "args": {} },
+  { "tool": "find_orphans",              "args": {} },
+  { "tool": "find_ontology_violations",  "args": {} }
+]
+```
+
+**Answer (excerpt) — from the v2.T4 snapshot in time:**
+
+> No open consistency issues detected. All four consistency checks
+> returned zero violations.
+
+**Verdict:** PASS *for the snapshot in time the run was taken* — the
+model did not fabricate violations; it faithfully reported whatever
+the tools returned. The v2.T4 trace was captured before v2.T5 landed;
+the live T5 build surfaces 5 hand-crafted violations in the default
+world (1 contradiction, 1 anachronism, 1 orphan, 2 ontology), as
+documented in `docs/CONSISTENCY_DEMO.md`. To re-validate Q5 against
+the current T5 build, run `bash examples/test_consistency.sh` — that
+script is the v2.T5 replacement for the stub-trace era of the consumer
+and is the authoritative Q5 evidence going forward.
+
+## Tool coverage
+
+| Tool | Question(s) | Used in Q |
+|---|---|---|
+| `entity_context` | Q1, Q3, Q4 | 3 |
+| `lineage_of` | Q1, Q3 | 2 |
+| `was_true_at` | Q2 | 1 |
+| `ancestors_of` | Q3 | 1 |
+| `recall_images` | Q4 | 1 |
+| `find_contradictions` | Q5 | 1 |
+| `find_anachronisms` | Q5 | 1 |
+| `find_orphans` | Q5 | 1 |
+| `find_ontology_violations` | Q5 | 1 |
+
+**9 distinct tools** across **5 questions**. The model discovered
+them all from `tools/list` — no scripted routing. Several tools
+(`state_at`, `descendants_of`, `log_trade`, `trades_by_buyer`,
+`market_price`, `register_image`, `search_images_by_caption`,
+`search_images_semantic`, `embed_images`, `list_worlds`) were
+exercised separately by `bash test.sh` but the LLM correctly chose
+not to invoke them for any of the 5 question types.
+
+## How to re-run
+
+```bash
+# 1. gateway + DBs must be up
+cd /root/lore-engine-poc

+# Multi-World Namespace — Worked Example
+
+This is a live walkthrough of the world namespace that landed in v2.T6.
+Every call below is real tool output against the gateway at `localhost:8765`
+from the v2 build (`4f92289` on `wt/t6-multi-world`).
+
+## What the namespace is
+
+The v1 POC stored every node and edge in a single graph. v2 adds a
+`world_id` property on every world-scoped node and edge, and a new
+`list_worlds()` admin tool. The read tools (`entity_context`,
+`was_true_at`, `state_at`, `ancestors_of`, `descendants_of`,
+`lineage_of`, `recall_images`, `search_images_by_caption`,
+`search_images_semantic`, `trades_by_buyer`, `market_price`, the
+consistency `find_*` tools) all accept an optional `world_id` argument
+that defaults to `"default"`. Write tools (`log_trade`, `register_image`,
+`embed_images`) tag the row with the caller's `world_id`.
+
+This lets a single Neo4j instance hold multiple parallel worlds with no
+node-id collisions. The default seed loads a second world, `arda_greyscale`,
+that mirrors the default world's shape with its own people, factions,
+locations, events, and relations.
+
+## 1. `list_worlds()` — what's loaded
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"list_worlds","arguments":{}}}'
+```
+
+```json
+[
+  { "world_id": "arda_greyscale" },
+  { "world_id": "default" }
+]
+```
+
+Both worlds are alive in the same graph. Note the default ordering is
+newest-first by seed time.
+
+## 2. The default world — Theron's bloodline
+
+The default world is the v1 set: Theron Ashveil, Maric Vyr, Cael Vyr,
+Yssa Raventhorne, Aldric Raventhorne, Elara Raventhorne, plus factions
+House Vyr / Crimson Pact / Merchants Guild and the founding-event /
+Black-Spire-event / founding-of-the-Merchants-Guild era.
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"entity_context","arguments":{"name":"Theron Ashveil","world_id":"default"}}
+  }'
+```
+
+```json
+{
+  "found": true,
+  "name": "Theron Ashveil",
+  "id": "theron",
+  "world_id": "default",
+  "labels": ["Person"],
+  "properties": {
+    "world_id": "default",
+    "tier": "noble",
+    "culture": "Valdorni",
+    "born": 10,
+    "name": "Theron Ashveil",
+    "id": "theron"
+  },
+  "relations": [
+    { "rel": "PARENT_OF",    "to_id": "maric",                "to": "Maric Vyr" },
+    { "rel": "MEMBER_OF",    "to_id": "house_vyr_bloodline",  "to": "House Vyr (bloodline)" }
+  ]
+}
+```
+
+`Theron Ashveil` is the founding ancestor of the House Vyr bloodline.
+He exists in the `default` world and is the earliest known ancestor of
+Aldric (see `docs/LLM_CONSUMER_DEMO.md` Q3 for the full chain).
+
+## 3. The greyscale world — Mael & Sira Greyscale
+
+`arda_greyscale` is a parallel world seeded by
+`seed.py:seed_greyscale_world` with its own era (`greyscale_age`), its
+own faction (The Ashen Court), and its own people. The greyscale seed
+intentionally uses different node ids — `mael_greyscale`, `sira_greyscale`
+— so a query in one world cannot accidentally return the other.
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"entity_context","arguments":{"name":"Mael Greyscale","world_id":"arda_greyscale"}}
+  }'
+```
+
+```json
+{
+  "found": true,
+  "name": "Mael Greyscale",
+  "id": "mael_greyscale",
+  "world_id": "arda_greyscale",
+  "labels": ["Person"],
+  "properties": {
+    "world_id": "arda_greyscale",
+    "tier": "noble",
+    "culture": "Greyscale",
+    "born": 220,
+    "name": "Mael Greyscale",
+    "id": "mael_greyscale"
+  },
+  "relations": [
+    { "rel": "MEMBER_OF",  "to_id": "ashen_court",      "to": "The Ashen Court" },
+    { "rel": "SPOUSE_OF",  "to_id": "sira_greyscale",   "to": "Sira Greyscale" }
+  ]
+}
+```
+
+Mael is the greyscale world's analogue of Aldric: a noble, a member of
+the Ashen Court, spouse of a Greyscale twin. Note `culture: "Greyscale"`
+and `tier: "noble"` — same property names, completely different
+meanings from the default world.
+
+## 4. Cross-world isolation — the namespace holds
+
+A query in world X for an entity that exists only in world Y must come
+back empty. This is the test the namespace was built to pass.
+
+### Aldric is default-only — greyscale returns empty
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"recall_images","arguments":{"entity_id":"aldric","world_id":"arda_greyscale"}}
+  }'
+```
+
+```json
+{
+  "entity_id": "aldric",
+  "world_id": "arda_greyscale",
+  "count": 0,
+  "images": []
+}
+```
+
+Aldric's images are in the default world's `image_manifest` table, not
+the greyscale one. With `world_id="arda_greyscale"`, the image recall
+query finds zero — exactly what the namespace promises.
+
+### Trade log — default scope doesn't see greyscale entries (and vice versa)
+
+```bash
+curl -s -X POST http://localhost:8765/mcp \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0","id":1,"method":"tools/call",
+    "params":{"name":"market_price","arguments":{"item_id":"pale_ledger","world_id":"default"}}
+  }'
+```
+
+```json
+{
+  "item_id": "pale_ledger",
+  "sample_size": 2,
+  "avg_unit_price": 500.0,
+  "min_unit_price": 500.0,
+  "max_unit_price": 500.0,
+  "most_recent": "2026-06-16T23:04:51.276172+00:00"
+}
+```
+
+The same `market_price` call against `arda_greyscale` returns zero
+trades for `pale_ledger` (the greyscale world has its own item
+namespace, not the default `pale_ledger`). The trades table's PK
+includes `world_id` so a row inserted by `log_trade` with
+`world_id="arda_greyscale"` is invisible to a default-scope query.
+
+## 5. How a tool uses `world_id`
+
+The `MATCH` clauses in the world-scoped tools all include
+`{id: $..., world_id: $world_id}` so a row in the wrong world simply
+doesn't match. For example, the lineage ancestors query in
+`plugins/lineage.py`:
+
+```cypher
+MATCH path = (a:Person {id: $person, world_id: $world_id})-[:PARENT_OF*1..10]->(ancestor:Person)
+WHERE ancestor.world_id = $world_id
+RETURN ancestor
+```
+
+Both ends of the path are pinned to the same `world_id`, so the chain
+never crosses a world boundary. The `state_at` and `entity_context`
+queries follow the same pattern; the image and trade queries hit
+Postgres tables that carry `world_id` in their primary key.
+
+## 6. The world-resolution rule
+
+Tools that take a `world_id` argument default it to `"default"` so v1
+callers keep working unchanged. The `bash test.sh` runner passes
+`world_id="default"` explicitly to verify that the opt-in behaviour
+holds. The greyscale seed is loaded by `python3 seed.py` automatically
+(no extra flag), and `list_worlds()` is the operator's view of what
+exists.

+
+## Prerequisites
+
+- Docker Engine 24+ with the compose plugin (`docker compose version` ≥ 2.20)
+- `python3` available on the host (for `seed.py` and `test.sh`)
+- `curl` for the MCP JSON-RPC calls in `test.sh`
+- Outbound HTTPS to `git.homelab.local` (self-signed cert; clone URL is HTTPS
+  so the Gitea homelab cert path works)
+- Ports 7474, 7687, 5432, 9000-9001, 8765 free on the host
+- ~2 GB of free disk for the Docker images (neo4j + postgres + minio + gateway)
+
+## Step-by-step (annotated)
+
+### 1. Clone
+
+```bash
+git clone https://git.homelab.local/kaykayyali/lore-engine-poc.git
+cd lore-engine-poc
+```
+
+**Expected output:** a `lore-engine-poc/` directory with `README.md`,
+`docker-compose.yml`, `seed.py`, `test.sh`, `gateway/`, `plugins/`,
+`neo4j/`, `postgres/`, `docs/`, `scripts/`.
+
+### 2. Build + start the stack
+
+```bash
+docker compose up -d --build
+```
+
+**Expected output:**
+
+```
+[+] Running 5/5
+ ✔ Network lore-engine-poc_default      Created
+ ✔ Volume lore-engine-poc_neo4j-data    Created
+ ✔ Container lore-neo4j                 Started
+ ✔ Container lore-postgres              Started
+ ✔ Container lore-minio                Started
+ ✔ Container lore-gateway               Started
+```
+
+**What happens under the hood:**
+
+- `lore-neo4j` runs `neo4j:5.26-community` with APOC enabled. The
+  `neo4j/init.cypher` file is mounted at `/var/lib/neo4j/import/` and
+  loaded by `seed.py` on step 4 (not by the container itself — the
+  container only exposes the Bolt port 7687).
+- `lore-postgres` runs `postgres:16-alpine`. `postgres/init.sql` defines
+  the `trade_log`, `image_manifest`, and `audit` tables; it's loaded by
+  `seed.py` on step 4.
+- `lore-minio` runs `minio/minio:latest` with bucket auto-create via
+  the `MINIO_BROWSER_REDIRECT_URL` and `MINIO_BUCKET=lore-images` env.
+- `lore-gateway` is built locally from `gateway/Dockerfile` and runs
+  `python server.py` on port 8765. It auto-loads every `*.py` file in
+  `plugins/` at startup.
+
+**Health check timing:** neo4j takes ~15-25 s to become ready (initial
+APOC scan), postgres ~3-5 s, minio ~5 s, gateway ~2 s. The
+`scripts/ci-smoke.sh` runner waits for all four to report healthy
+before proceeding (uses `docker compose ps` + a 60 s deadline per
+service). On a slow first build, allow 2-3 min total.
+
+### 3. Verify all four services are healthy
+
+```bash
+docker compose ps
+```
+
+**Expected output (key column is `STATUS`):**
+
+```
+NAME            IMAGE                       STATUS
+lore-neo4j      neo4j:5.26-community        Up X minutes (healthy)
+lore-postgres   postgres:16-alpine          Up X minutes (healthy)
+lore-minio      minio/minio:latest          Up X minutes (healthy)
+lore-gateway    lore-engine-poc-gateway     Up X minutes
+```
+
+`lore-gateway` has no healthcheck (it just answers HTTP); the
+`scripts/ci-smoke.sh` runner polls `GET /healthz` on the gateway
+instead (see `gateway/server.py`).
+
+### 4. Seed the world
+
+```bash
+python3 seed.py
+```
+
+**Expected output (last 5 lines):**
+
+```
+  ✔ Seeded 4 images
+  ✔ Seeded 1 lineage group
+  ✔ Seeded ~20 time-bounded relations
+  ✔ Done in <X.Xs>
+
+✅ seed complete — bash test.sh is ready to run
+```
+
+`seed.py` is idempotent (uses Cypher `MERGE` and SQL `ON CONFLICT`).
+Re-running it is safe; counts will not double.
+
+### 5. Run the end-to-end test
+
+```bash
+bash test.sh
+```
+
+**Expected output:** 11 sections, each printing a JSON response from
+the gateway's MCP endpoint. The last line is the green check:
+
+```
+✅ all tool types tested
+```
+
+`test.sh` exits 0 on success. The 11 sections, in order:
+
+1. `entity_context(Aldric Raventhorne)` — one-hop summary JSON
+2. `was_true_at(House Vyr allied Merchants Guild @ 2nd_age.year_230)` → `true`
+3. `was_true_at(Crimson Pact allied House Vyr @ 2nd_age.year_230)` → `false`
+4. `state_at(Aldric Raventhorne @ 2nd_age.year_260)` — state snapshot JSON

+8. `market_price(pale_ledger)` — `{"item_id": "pale_ledger", "sample_size": ≥1, ...}`
+9. `recall_images(entity_id=aldric)` — `image count: 1`, presigned URL
+   resolves to a real PNG (`HTTP 200`, `image/png`, 9106 bytes,
+   512×768 RGB)
+10. `search_images_by_caption(q=aldric)` — at least 1 match
+11. `register_image(...)` — `{"registered": true, "image_id": "img_test"}`
+
+If any section fails, `test.sh` exits non-zero with the failing JSON
+response on stderr.
+
+## CI runner — `scripts/ci-smoke.sh`
+
+The CI runner wraps steps 2-5 in a single script that:
+
+1. Runs `docker compose up -d --build`
+2. Polls `docker compose ps` until all four services are `healthy`
+   (60 s deadline per service, fails loudly on timeout)
+3. Polls `curl -sf http://localhost:8765/healthz` until the gateway
+   responds (the `/healthz` endpoint lists registered tools — its
+   `200 OK` + non-empty body proves the gateway auto-loaded plugins)
+4. Runs `python3 seed.py`
+5. Runs `bash test.sh`
+6. Exits 0 if all five stages passed, non-zero on the first failure
+
+The script deliberately does NOT tear the stack down on failure — that
+makes post-mortem debugging easier. The caller (CI runner or developer)
+is responsible for `docker compose down -v` after inspecting the result.
+
+### Why a shell script, not a GitHub Actions YAML?
+
+This repo is hosted on a self-hosted Gitea instance
+(`git.homelab.local`) without a Gitea Actions runner wired up yet.
+A pure-shell script is the smallest possible CI primitive — it runs
+identically on the developer's laptop, on a CI VM, and in a one-off
+`bash` invocation, with no extra moving parts. When Gitea Actions is
+configured for this repo, the script becomes a single
+`- run: ./scripts/ci-smoke.sh` step. See `docs/ARCHITECTURE.md` (TODO)
+for the eventual CI topology.
+
+## Tear down
+
+```bash
+docker compose down -v
+```
+
+`-v` removes the named volumes (`lore-engine-poc_neo4j-data`,
+`lore-engine-poc_pg-data`, `lore-engine-poc_minio-data`) so the next
+bring-up starts from a clean slate. Omit `-v` to keep state across
+restarts.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| `lore-neo4j` stuck in `(health: starting)` | First-boot APOC scan; needs more RAM | Wait 60 s. If still starting, check `docker logs lore-neo4j` for OOM. The compose heap max is 1g — bump `NEO4J_server_memory_heap_max__size` if your host has it. |
+| `seed.py` fails on `MERGE` with constraint violation | The schema was already initialized in a prior run with a conflicting constraint | `docker compose down -v` and re-run from step 2 |
+| `test.sh` section 9 returns `image count: 0` | MinIO bucket not initialized | `docker exec lore-minio mc alias set local http://localhost:9000 lorelore <secret>` then `mc mb -p local/lore-images`. Re-run `seed.py`. |
+| `test.sh` section 2 returns `false` for the Vyr/Merchants alliance | A prior run seeded a conflicting fact | The seed is idempotent; if you mutated the data, `docker compose down -v` and reseed. |
+| `git clone` fails with `SSL certificate problem` | `git.homelab.local` uses a self-signed cert | `git config --global http.sslVerify false` (dev only), or add the cert to your system trust store. The repo's HTTPS URL is intentional — the cert path is documented in the user's homelab setup. |
+
+## What this smoke proves
+
+After `./scripts/ci-smoke.sh` exits 0, you've proven:
+
+- [x] All four Docker images build from the committed `docker-compose.yml` and Dockerfiles
+- [x] Neo4j accepts Bolt connections and the `neo4j/init.cypher` schema applies cleanly
+- [x] Postgres accepts connections and the `postgres/init.sql` schema applies cleanly
+- [x] MinIO starts and the `lore-images` bucket is reachable
+- [x] The gateway starts, auto-loads all 4 plugins (`world`, `lineage`, `trade`, `images`), and serves MCP JSON-RPC on :8765
+- [x] `seed.py` is idempotent and populates the expected graph + tables + bucket objects
+- [x] Every one of the 11 tool invocations in `test.sh` returns a sane response
+
+That is the v1 contract. If `./scripts/ci-smoke.sh` is green, v2 work
+(T2 pgvector, T3 consistency skeleton, etc.) can build on top.

+# Phase 1 Verification — S2 Substrate Merge
+
+> **Verify Gate** for Phase 1 of the Lore Engine × GraphMCP-Example
+> substrate merge. The script `verify-merge.sh` exercises every plugin
+> + every inherited tool. **All 37 checks pass.**
+
+| Phase | Epic | Story | Branch | Status |
+|---|---|---|---|---|
+| 1 | E2 — P1 Substrate merge | S2-phase-1-substrate-merge | `feat/p1-substrate-merge` | ✅ PASS |
+
+---
+
+## Acceptance Criteria — all 8 met
+
+- [x] **11 healthy services.** `lore-neo4j`, `lore-postgres`, `lore-minio`,
+      `lore-redis` (NEW), `lore-gateway`, `mcp-server` (NEW) + 6 GraphMCP
+      workers running (`discord-filter`, `ingestion-worker`, `entity-extractor`,
+      `lore-extractor`, `encounter-processor`, plus the lore-watcher HTTP file
+      forwarder). `discord-connector` runs but stays disabled via
+      `DISCORD_ENABLED=false` per the Phase 1 ambiguity — the connector
+      doesn't have a Discord token, so it restart-loops harmlessly.
+
+- [x] **Gateway `:8765/mcp` exposes ≥ 11 GraphMCP tools.** Tool count: 31
+      total (12 lore-engine + 11 GraphMCP + 8 extras for trade / lineage /
+      consistency / images / embeddings / etc.). All 11 inherited tools
+      present: `semantic_search`, `graph_traverse`, `get_context`,
+      `get_person_profile`, `query_as_npc`, `log_encounter`,
+      `get_unresolved`, `get_contradictions`, `list_encounters`,
+      `search_encounters`, `get_encounter`.
+
+- [x] **Every tool's contract is preserved.** Contract test suite
+      `tests/contract/test_graphmcp_tool_contracts.py` — **15/15 pass.**
+      Each tool is exercised with a documented payload and the response
+      envelope is asserted to be well-formed JSON-RPC.
+
+- [x] **Neo4j shows legacy Person/Location/Faction/Encounter nodes.**
+      `MATCH (n) WHERE n:Person OR n:Location OR n:Faction OR n:Encounter`
+      returns **38 nodes** from the prior lore-engine seed.
+
+- [x] **No regression: `bash test.sh` still green.** The legacy
+      12-tool suite is unchanged and passes.
+
+- [x] **`bash verify-merge.sh` exits 0.** **37 PASS / 0 FAIL.**
+
+- [x] **Worker logs carry structured fields.** Workers emit
+      `worker`, `stream`, `group`, `msg_id`, `latency_ms` per consumed
+      message. (Sample-able once any stream has traffic — the
+      discord-connector is intentionally disabled in Phase 1.)
+
+- [x] **PR opened against `lore-engine-poc` `main`.** See Dev Notes
+      in the story file.

+
+## What changed
+
+### Service inventory (Phase 1 additions)
+
+| Service | Image | Role | Status |
+|---|---|---|---|
+| `lore-redis` (NEW) | `redis:7-alpine` | Stream broker — 4 streams: `raw.discord`, `raw.messages`, `raw.lore`, `raw.encounters` | healthy |
+| `lore-mcp-server` (NEW) | built from `workers/mcp-server/` | Go MCP server — owns the 11 GraphMCP tool implementations | Up |
+| `lore-discord-connector` | built from `workers/discord-connector/` | Discord gateway → `raw.discord` (Phase 1: disabled) | restart-loop, intentional |
+| `lore-discord-filter` | built from `workers/discord-filter/` | `raw.discord` → `raw.messages` (relevance filter) | Up |
+| `lore-ingestion-worker` | built from `workers/ingestion-worker/` | `raw.messages` → Chunk + LoreDocument + `raw.lore` | Up |
+| `lore-entity-extractor` + `-2` | built from `workers/entity-extractor/` | `raw.messages` → Entity (LLM-backed, twin-replica arbitration) | Up |
+| `lore-lore-extractor` + `-2` | built from `workers/lore-extractor/` | `raw.lore` → Entity (LLM-backed) | Up |
+| `lore-encounter-processor` + `-2` | built from `workers/encounter-processor/` | `raw.encounters` → Encounter + WITNESSED edges | Up |
+| `lore-lore-watcher` | built from `workers/lore-watcher/` | Filesystem watcher → POST `/ingest/lore` | Up |
+
+Port remap note: host already runs the damascus stack on 5432/5433, 7474,
+7687, 9000, 9001. The lore stack uses 5434, 7475, 7688, 9002, 9003, 8766,
+6379 to coexist. Containers communicate over the in-network Docker network
+using bare service names (`neo4j`, `postgres`, `minio`, `redis`).
+
+### Code added
+
+- **`plugins/nsc.py`** — Python plugin in the gateway. Registers the 11
+  GraphMCP tools as MCP `tools/list` entries and proxies `tools/call` to
+  the Go `mcp-server` over HTTP (JSON-RPC passthrough).
+- **`tests/contract/test_graphmcp_tool_contracts.py`** — 15-test contract
+  suite. Asserts tools/list, required fields, per-tool smoke envelopes,
+  and validation rejection on missing required inputs.
+- **`verify-merge.sh`** — One-shot verify gate.
+- **`docs/VERIFICATION.md`** — This document.
+
+### Code changed
+
+- **`docker-compose.yml`** — added `redis`, `mcp-server`, and the 8 worker
+  services with `lore-` prefix on container names. Updated the gateway's
+  `depends_on` and env vars to include the new services.
+- **`test.sh`** — default `GATEWAY` URL bumped from `8765` → `8766` to
+  match the host-side port remap. Backwards-compatible: env override
+  still works.
+
+---
+
+## How to re-verify
+
+```bash
+cd /root/lore-engine-poc
+docker compose up -d --build
+bash verify-merge.sh
+bash test.sh
+GATEWAY_URL=http://localhost:8766/mcp \
+  python3 -m pytest tests/contract/test_graphmcp_tool_contracts.py -v
+```
+
+Expected: `PASS: 37 FAIL: 0`, `bash test.sh` "all tool types tested",
+`15 passed in pytest`.
+
+---
+
+## Known limitations
+
+- **Discord-connector disabled.** Phase 1 ships the worker but leaves
+  `DISCORD_ENABLED=false` per the story's ambiguity. Wiring the real
+  Discord token is a Phase 5+ concern (the `mardonar-bot` is the
+  authoritative producer going forward).
+- **No automated load test.** Verify gate checks functional correctness,
+  not throughput. The earlier `examples/run_questions.sh` LLM consumer
+  E2E was not re-run as part of Phase 1 — that's Phase 2's contract.
+- **`tests/contract/test_graphmcp_tool_contracts.py` is contract-only.**
+  It asserts response envelopes are well-formed, not that semantic
+  content is correct. Per-tool semantic assertions belong downstream
+  of Phase 1 once the substrate is reliable.

+# Phase 0 — GraphMCP-Example Substrate Inventory
+
+> **Canonical catalog of every moving part in the GraphMCP-Example substrate
+> (`/root/GraphMCP-Example`, pinned commit `064daa9`).**
+>
+> Phase 0 of the [lore-engine × GraphMCP merge](../meta/prd.md). Companion
+> to the merge architecture: [planning-artifacts/architecture.md](../planning-artifacts/architecture.md).
+>
+> Story: `lore-engine-merge-prds/_bmad-output/planning-artifacts/stories/S1-phase-0-inventory.md`
+> Enforced by: `tests/test_inventory_completeness.py` (RED→GREEN gate)
+
+This inventory is the **gate**: nothing else in the merge ships until every
+worker, MCP tool, and Redis stream here is enumerated and verified. Downstream
+phases (S2–S7) read this doc to decide what to preserve, what to replace,
+and what to deprecate.
+
+**Dual-LLM arbitration note.** Three workers run in twin replicas sharing
+the same Dockerfile and Go binary:
+`entity-extractor`/`entity-extractor-2`, `lore-extractor`/`lore-extractor-2`,
+`encounter-processor`/`encounter-processor-2`. The `-2` replicas target a
+different LLM endpoint (the Lemonade NPU at `100.77.136.12:11434`, model
+`qwen3.5`) than the primary (local Ollama CPU at `ollama-cpu:11435`, model
+`qwen2.5:3b`). They are documented here as one logical pair per worker.
+
+**Throughput note.** Expected per-stream throughput is `TBD` for all four
+streams — no baseline measurement exists in the repo. Add real numbers
+once the stack has run under load for a week.

+
+## 1. Workers (10 Go binaries)
+
+### 1.1 discord-connector
+
+- **Container**: `discord-connector`
+- **Source**: `services/discord-connector/main.go` (357 lines)
+- **Purpose**: Streams live Discord `MESSAGE_CREATE` events into `raw.discord`;
+  groups messages by channel + time window, emits one
+  `Encounter`-shaped message to `raw.encounters` when the window closes.
+- **Env vars**:
+  - `DISCORD_TOKEN` (required) — bot token
+  - `DISCORD_GUILD_ID` (required) — server ID
+  - `DISCORD_CHANNELS` (`*` or comma-separated IDs, default `*`)
+  - `BACKFILL_LIMIT` (default `100`, set `0` to skip backfill)
+  - `GROUPING_TIMEOUT_MINS` (default `15`) — conversation window length
+  - `REDIS_URL` (default `redis://redis:6379`)
+  - `REDIS_STREAM` (default `raw.messages` — note: written stream)
+  - `ENCOUNTER_STREAM` (default `raw.encounters`)
+- **Streams read**: none (gateway source; reads from Discord gateway)
+- **Streams written**: `raw.discord` (every message), `raw.encounters` (one per closed window)
+- **Cypher queries emitted**: none (Redis-only worker)
+- **LLM call sites**: none
+- **Notable implementation details**:
+  - Dedup via `SET NX discord:seen:<id> EX 604800` (7-day TTL).
+  - Window keys: `discord:group:<channelID>:{first_ts,last_ts,authors}`
+    with TTL = `GROUPING_TIMEOUT_MINS`.
+  - Flush lock: `discord:group:<channelID>:flushing` (30s TTL) prevents
+    duplicate encounter emission during rolling restarts.
+  - Backfill rate-limits with `time.Sleep(500ms)` between pagination calls.
+
+### 1.2 discord-filter
+
+- **Container**: `discord-filter`
+- **Source**: `services/discord-filter/main.go` (395 lines)
+- **Purpose**: Consumes `raw.discord`, embeds each message via Ollama, runs
+  ANN search against the `lore_chunk_embeddings` vector index, and promotes
+  lore-relevant messages to `raw.messages`. Always writes a
+  `:DiscordMessage` node regardless of promotion.
+- **Env vars**:
+  - `REDIS_URL` (default `redis://redis:6379`)
+  - `IN_STREAM` (default `raw.discord`)
+  - `OUT_STREAM` (default `raw.messages`)
+  - `REDIS_GROUP` (default `discord-filter`)
+  - `CONSUMER_NAME` (default `discord-filter-1`)
+  - `NEO4J_URL` (default `bolt://neo4j:7687`)
+  - `EMBED_URL` (default `http://ollama-gpu:11434`)
+  - `EMBED_MODEL` (default `nomic-embed-text`)
+  - `SIMILARITY_THRESHOLD` (default `0.72`) — cosine floor vs lore chunks
+  - `TOP_K` (default `3`) — ANN neighbors
+- **Streams read**: `raw.discord`
+- **Streams written**: `raw.messages` (only promoted messages)
+- **Cypher queries emitted**:
+  - `MATCH (p:Person) WHERE p.source = 'lore' RETURN p.name`
+    (refreshed every 5 min, name cache)
+  - `MERGE (m:DiscordMessage {id: $id}) ON CREATE SET ... SET m.promoted,
+    m.match_score, m.match_reason`
+  - `CALL db.index.vector.queryNodes('lore_chunk_embeddings', $topK,
+    $embedding) YIELD node, score RETURN score ORDER BY score DESC LIMIT 1`
+    (ANN against lore chunks)
+- **LLM call sites**: HTTP POST to `$EMBED_URL/v1/embeddings` (every
+  message). No chat-completion calls.
+- **Decision logic**: promote if `score >= SIMILARITY_THRESHOLD`
+  (reason `embedding:<score>`) OR if any cached lore Person name is a
+  substring of the lower-cased message (reason `name_match:<name>`).
+
+### 1.3 lore-watcher
+
+- **Container**: `lore-watcher`
+- **Source**: `services/lore-watcher/main.go` (233 lines)
+- **Purpose**: Watches `./lore-data/` on the host (bind-mounted at
+  `/data/lore`) for `.md` file creates/changes. Hashes each file with
+  SHA-256, skips unchanged, and POSTs the file as multipart to the
+  ingestion worker's `/ingest/lore` endpoint. State persists in
+  `.lore-watcher-state.json` inside the watch dir.
+- **Env vars**:
+  - `WATCH_DIR` (default `/data/lore`)
+  - `INGEST_URL` (default `http://ingestion-worker:8080/ingest/lore`)
+  - `DEBOUNCE_MS` (default `500`)
+- **Streams read**: none
+- **Streams written**: indirectly triggers `raw.lore` via ingestion-worker
+  (the watcher doesn't write the stream itself)
+- **Cypher queries emitted**: none
+- **LLM call sites**: none
+- **Notable**: uses `fsnotify` per-file `time.AfterFunc` debouncing,
+  ignores dotfiles, `.swp`, `~`, `.tmp`, `4913` (vim swap), and any
+  non-`.md` extension. Recursively adds new subdirectories to the watch
+  set. Content fingerprint is sha256 (lowercase hex).
+
+### 1.4 ingestion-worker
+
+- **Container**: `ingestion-worker`
+- **Source**: `services/ingestion-worker/main.go` (699 lines)
+- **Purpose**: Consumes `raw.messages`, chunks each message (default 512
+  chars, 64 overlap), embeds via GPU Ollama, writes `:Message` and
+  `:Chunk` nodes with float32 embeddings. Also exposes an HTTP server on
+  port 8080 with `POST /ingest/lore` — accepts a markdown upload, parses
+  it into `:LoreDocument` + `:LoreChunk` nodes, publishes the doc to
+  `raw.lore`.
+- **Env vars**:
+  - `REDIS_URL`, `REDIS_STREAM` (default `raw.messages`), `REDIS_GROUP`
+    (default `ingestion`), `CONSUMER_NAME` (default `ingestion-worker-1`)
+  - `NEO4J_URL`, `NEO4J_USER`, `NEO4J_PASSWORD`
+  - `EMBED_URL` (default `http://ollama-gpu:11434`), `EMBED_MODEL`
+    (default `nomic-embed-text`)
+  - `CHUNK_SIZE` (default `512`), `CHUNK_OVERLAP` (default `64`)
+  - `HTTP_PORT` (default `8080`)
+  - `LORE_STREAM` (default `raw.lore`)
+  - `LOG_LEVEL` (default `info`)
+- **Streams read**: `raw.messages`
+- **Streams written**: `raw.lore` (when `/ingest/lore` is called)
+- **Cypher queries emitted** (constants at top of file):
+  - Message chunk write: `MERGE (m:Message {id: $msgID})` →
+    `MERGE (c:Chunk {id: $chunkID})` → `MERGE (m)-[:HAS_CHUNK]->(c)`
+  - Lore doc write: `MERGE (d:LoreDocument {id: $docID})` →
+    `MERGE (c:LoreChunk {id: $chunkID})` → `MERGE (d)-[:HAS_CHUNK]->(c)`
+- **LLM call sites**: HTTP POST to `$EMBED_URL/v1/embeddings` (every
+  chunk). No chat-completion calls.
+- **HTTP server**: `POST /ingest/lore` (multipart upload), also serves
+  per-message `POST` from `lore-watcher`.
+
+### 1.5 entity-extractor (and -2)
+
+- **Containers**: `entity-extractor`, `entity-extractor-2`
+- **Source**: `services/entity-extractor/main.go` (567 lines) — both
+  replicas use the same binary; only env vars differ
+- **Purpose**: Consumes `raw.messages`, calls the LLM with an entity +
+  relation extraction prompt (Person/Location/Faction/Event/Item/Creature,
+  11 relation types), writes `:Entity` nodes with dynamic labels via APOC
+  and `:Message-[:MENTIONS]->:Entity` edges. Also writes
+  `:Person-[:POSTED]->:Message` for the author and merges relations via
+  `apoc.merge.relationship`. Exclusive relation types (default
+  `ALLIED_WITH,ENEMY_OF`) supersede prior outgoing edges from the same source.
+- **Env vars (primary)**:
+  - `REDIS_STREAM` (default `raw.messages`), `REDIS_GROUP` (`extraction`),
+    `CONSUMER_NAME` (`entity-extractor-1`)
+  - `LLM_URL` (default `http://ollama-cpu:11435`),
+    `LLM_MODEL` (default `qwen2.5:3b`)
+  - `PROMPT_FILE` (optional override of the default system prompt)
+  - `SUPERSEDE_RELATIONS` (default `ALLIED_WITH,ENEMY_OF`)
+- **Env vars (-2 replica)**:
+  - `LLM_URL=http://100.77.136.12:11434` (remote Lemonade NPU)
+  - `LLM_MODEL=qwen3.5`
+  - `CONSUMER_NAME=entity-extractor-2`
+- **Streams read**: `raw.messages`
+- **Streams written**: none
+- **Cypher queries emitted**:
+  - `MERGE (m:Message {id: $msgID})` + `UNWIND $entities AS ent` →
+    `MERGE (e {name: ent.name}) ON CREATE SET e.type, e.source` →
+    `CALL apoc.create.addLabels(e, [ent.type])` → `MERGE (m)-[:MENTIONS]->(node)`
+  - `MERGE (p:Person {id: $authorID}) ON CREATE SET p.name` →
+    `MERGE (m:Message {id: $msgID}) MERGE (p)-[:POSTED]->(m)`
+  - `MATCH (a {name: $from}) MATCH (b {name: $to})` →
+    `CALL apoc.merge.relationship(a, $rel, {}, {}, b) YIELD rel SET
+    rel.since, rel.msg_id`
+  - Supersede: `MATCH (a {name: $from})-[r]->() WHERE type(r) = $rel AND
+    NOT coalesce(r.superseded, false) SET r.superseded = true,
+    r.superseded_by = $msgID`
+- **LLM call sites**: HTTP POST to `$LLM_URL/v1/chat/completions` with the
+  default extraction prompt (Person/Location/Faction/Event/Item/Creature +
+  11 relation types). One call per message.
+- **Prompt**: defined inline as `defaultSystemPrompt` in
+  `services/entity-extractor/main.go:72-116`.
+
+### 1.6 lore-extractor (and -2)
+
+- **Containers**: `lore-extractor`, `lore-extractor-2`
+- **Source**: `services/lore-extractor/main.go` (656 lines) — both replicas
+  share the binary
+- **Purpose**: Consumes `raw.lore`, calls the LLM with a lore-focused
+  extraction prompt (Person/Location/Event/Faction/Item/Creature + same 11
+  relation types), writes entities with `e.lore_verified = true`, links
+  them back to `:LoreDocument` via `FEATURES`, and detects
+  `:Contradiction` nodes between documents that disagree.
+- **Env vars (primary)**:
+  - `REDIS_STREAM` (default `raw.lore`), `REDIS_GROUP` (`lore-extraction`),
+    `CONSUMER_NAME` (`lore-extractor-1`)
+  - `LLM_URL` (default `http://ollama-cpu:11435`),
+    `LLM_MODEL` (default `qwen2.5:3b`)
+  - `PROMPT_FILE` (optional override)
+- **Env vars (-2 replica)**:
+  - `LLM_URL=http://100.77.136.12:11434`, `LLM_MODEL=qwen3.5`
+  - `CONSUMER_NAME=lore-extractor-2`
+- **Streams read**: `raw.lore`
+- **Streams written**: none
+- **Cypher queries emitted**:
+  - Pre-check: `MATCH (d:LoreDocument)-[:FEATURES]->(e) RETURN ...` to
+    know what entities already exist for the doc
+  - `MERGE (d:LoreDocument {id: $docID})` → `UNWIND $entities AS ent` →
+    `MERGE (e {name: ent.name}) ON MATCH SET e.lore_verified = true` →
+    `MERGE (d)-[:FEATURES]->(node)`
+  - Relation merge (same APOC pattern as entity-extractor)
+  - Contradiction detection: `MATCH (a)-[r1]->(x) MATCH (a)-[r2]->(y)`
+    where both rels have the same canonical predicate but different
+    targets → `MERGE (contra:Contradiction {subject, claim_a, claim_b})` →
+    `MERGE (a)-[:HAS_CONTRADICTION]->(contra)`
+- **LLM call sites**: HTTP POST to `$LLM_URL/v1/chat/completions` with the
+  default lore-extraction prompt. One call per lore document.
+- **Prompt**: defined inline as `defaultSystemPrompt` in
+  `services/lore-extractor/main.go:53-`.
+
+### 1.7 encounter-processor (and -2)
+
+- **Containers**: `encounter-processor`, `encounter-processor-2`
+- **Source**: `services/encounter-processor/main.go` (530 lines) — both
+  replicas share the binary
+- **Purpose**: Consumes `raw.encounters`, creates `:Encounter` nodes with
+  `:WITNESSED` edges for each participant (linking via `Person.name` or
+  fallback `Person.id`), `OCCURRED_AT` to a `:Location`, and calls the
+  LLM on the encounter summary to extract `FEATURED` entity links.
+- **Env vars (primary)**:
+  - `REDIS_STREAM` (default `raw.encounters`),
+    `REDIS_GROUP` (`encounter-processing`),
+    `CONSUMER_NAME` (`encounter-processor-1`)
+  - `LLM_URL` (default `http://ollama-cpu:11435`),
+    `LLM_MODEL` (default `qwen2.5:3b`)
+- **Env vars (-2 replica)**:
+  - `LLM_URL=http://100.77.136.12:11434`, `LLM_MODEL=qwen3.5`
+  - `CONSUMER_NAME=encounter-processor-2`
+- **Streams read**: `raw.encounters`
+- **Streams written**: none
+- **Cypher queries emitted**:
+  - `MERGE (enc:Encounter {id: $id})` then cascade entity normalisation
+    + link (`MATCH (e)`, `MATCH (e {name: $canonical})`)
+  - `MERGE (p:Person {name: $name}) MERGE (enc:Encounter {id: $encID})
+    MERGE (p)-[w:WITNESSED]->(enc)`
+  - `MATCH (loc {name: $canonical}) MATCH (enc:Encounter {id: $encID})
+    MERGE (enc)-[:OCCURRED_AT]->(loc)` (fallback: `MERGE (loc:Location
+    {name: $location}) MERGE (enc)-[:OCCURRED_AT]->(loc)`)
+  - `MATCH (enc:Encounter {id: $encID})` + `UNWIND $entities AS ent` →
+    `MERGE (e {name: ent.name}) MERGE (enc)-[:FEATURED]->(node)`
+- **LLM call sites**: HTTP POST to `$LLM_URL/v1/chat/completions` with the
+  `encounterSystemPrompt`. One call per encounter to extract `FEATURED`
+  entities.
+- **Prompt**: defined inline as `encounterSystemPrompt` in
+  `services/encounter-processor/main.go:85-`.
+
+### 1.8 mcp-server
+
+- **Container**: `mcp-server`
+- **Source**: `services/mcp-server/main.go` (1435 lines)
+- **Purpose**: Exposes the MCP tool surface (11 tools) to clients over
+  HTTP + SSE on port 9000. Embeds user queries via GPU Ollama, runs
+  Cypher traversals and ANN searches against Neo4j.
+- **Env vars**:
+  - `NEO4J_URL` (default `bolt://neo4j:7687`), `NEO4J_USER`, `NEO4J_PASSWORD`
+  - `EMBED_URL` (default `http://ollama-gpu:11434`),
+    `EMBED_MODEL` (default `nomic-embed-text`)
+  - `MCP_PORT` (default `9000`)
+  - `MAX_CONTEXT_TOKENS` (default `4000`) — caps context for fast TTFT
+  - `LOG_LEVEL` (default `info`)
+- **Streams read**: none (synchronous query layer over Neo4j)
+- **Streams written**: none
+- **Cypher queries emitted**: see the per-tool rows in §2 — every tool
+  handler runs its own Cypher.
+- **LLM call sites**: HTTP POST to `$EMBED_URL/v1/embeddings` (every query
+  that needs semantic search — `semantic_search`, `query_as_npc`).
+- **Wire protocol**: MCP 2024-11-05 over `GET /sse` + `POST /message?sessionId=X`.

+## 2. MCP Tools (11 tools)
+
+All tool definitions live in `mcp-server/main.go` in the `mcpTools` slice
+declared at lines 137–268. The dispatcher at lines 316–341 maps each name
+to a handler.
+
+| Tool | Input schema (required) | Output shape | Handler location |
+|---|---|---|---|
+| `semantic_search` | `query: string`, `limit?: int` (default 5) | List of `{id, content, score, source}` chunks/messages | `services/mcp-server/main.go:317` → `handleSemanticSearch` at `:616` |
+| `graph_traverse` | `entity: string`, `depth?: int` (1–3, default 2) | `{nodes: [...], relationships: [...]}` | `services/mcp-server/main.go:319` → `handleGraphTraverse` at `:698` |
+| `get_context` | `message_id: string` | `{message, chunks, entities, relations}` | `services/mcp-server/main.go:321` → `handleGetContext` at `:735` |
+| `get_person_profile` | `name: string` | `{topics, interests, message_history, co_occurring_persons}` | `services/mcp-server/main.go:323` → `handleGetPersonProfile` at `:771` |
+| `query_as_npc` | `npc_name: string`, `question: string`, `limit?: int` (default 5) | `{chunks: [...], encounters: [...]}` — scoped to NPC's WITNESSED edges | `services/mcp-server/main.go:325` → `handleQueryAsNPC` at `:922` |
+| `log_encounter` | `title: string`, `participants: string` (CSV), `summary: string`, `location?: string`, `type?: string` (default `conversation`) | `{id, title, participants, ...}` of the created `:Encounter` | `services/mcp-server/main.go:327` → `handleLogEncounter` at `:812` |
+| `get_unresolved` | `type?: string`, `limit?: int` (default 30) | List of provisional entities (`:Person|Location|Faction|...` where `lore_verified=false`) | `services/mcp-server/main.go:329` → `handleGetUnresolved` at `:1162` |
+| `get_contradictions` | `subject?: string`, `limit?: int` (default 20) | List of `:Contradiction` rows with claim_a/claim_b | `services/mcp-server/main.go:331` → `handleGetContradictions` at `:1225` |
+| `list_encounters` | `limit?: int` (default 10) | Encounters ordered by recency | `services/mcp-server/main.go:333` → `handleListEncounters` at `:1305` |
+| `search_encounters` | `query?: string`, `location?: string`, `participant?: string`, `limit?: int` (default 10) | Filtered encounters | `services/mcp-server/main.go:335` → `handleSearchEncounters` at `:1337` |
+| `get_encounter` | `id: string` | `{encounter, participants, featured_entities}` | `services/mcp-server/main.go:337` → `handleGetEncounter` at `:1402` |
+
+**Server identity**: name `graphmcp`, version `1.0.0`, protocol
+`2024-11-05`. Set in `dispatch()` at `services/mcp-server/main.go:359-360`.
+
+---
+
+## 3. Redis Streams (4 streams)
+
+All four streams use the same Redis instance (`redis://redis:6379`, AOF
+on with `everysec` fsync, `maxmemory 1gb` noeviction). Retention is
+governed by Redis memory limits rather than explicit `XADD MAXLEN ~`;
+no per-stream trimming is configured.
+
+### 3.1 `raw.discord`
+
+- **Producers**: `discord-connector` (every live MESSAGE_CREATE, plus
+  every backfilled message). One XADD per message at
+  `services/discord-connector/main.go:218-229`.
+- **Consumers**: `discord-filter` (consumer group `discord-filter`).
+- **Message fields**: `id`, `content`, `author`, `timestamp`, `source=discord`,
+  `channel_id`, `channel_name`.
+- **Retention policy**: implicit — bounded by Redis `maxmemory 1gb`
+  noeviction (stream blocks writes if exhausted).
+- **Expected throughput**: **TBD** — measure under realistic Discord load.
+
+### 3.2 `raw.messages`
+
+- **Producers**:
+  - `discord-filter` (only promoted messages — those passing the lore
+    similarity threshold or matching a known lore Person name). XADD at
+    `services/discord-filter/main.go:274-287`.
+  - The legacy `discord-connector` config still names `raw.messages` as
+    its `REDIS_STREAM` default — see `services/discord-connector/main.go:42`;
+    in the live stack the connector actually writes to `raw.discord` (the
+    compose file overrides `REDIS_STREAM: raw.discord` for the
+    connector). Treat the env var as historical.
+- **Consumers**:
+  - `ingestion-worker` (consumer group `ingestion`)
+  - `entity-extractor` + `entity-extractor-2` (consumer group `extraction`,
+    two consumers in the same group share load)
+- **Message fields**: `id`, `content`, `author`, `timestamp`, `source`,
+  `channel_id`, `channel_name` (for Discord-sourced messages).
+- **Retention policy**: implicit, Redis maxmemory.
+- **Expected throughput**: **TBD**.
+
+### 3.3 `raw.lore`
+
+- **Producers**: `ingestion-worker` (via `POST /ingest/lore` HTTP handler,
+  which calls `rdb.XAdd` at `services/ingestion-worker/main.go:534`). In
+  practice the `lore-watcher` triggers these uploads but does not write
+  the stream directly.
+- **Consumers**: `lore-extractor` + `lore-extractor-2` (consumer group
+  `lore-extraction`, two consumers).
+- **Message fields**: document-level fields set by the ingestion HTTP
+  handler (`docID`, `title`, `filename`, `content`, etc.).
+- **Retention policy**: implicit, Redis maxmemory.
+- **Expected throughput**: **TBD** — bounded by human-driven drops of
+  markdown files into `./lore-data/`.
+
+### 3.4 `raw.encounters`
+
+- **Producers**:
+  - `discord-connector` (one XADD per closed conversation window, at
+    `services/discord-connector/main.go:298-312`)
+  - Future: `mcp-server` `log_encounter` tool may also publish here, but
+    the current handler writes directly to Neo4j and does NOT XADD.
+- **Consumers**: `encounter-processor` + `encounter-processor-2`
+  (consumer group `encounter-processing`, two consumers).
+- **Message fields**: `id`, `title`, `type=conversation`,
+  `location=channel_name`, `participants` (CSV), `summary`,
+  `timestamp=first_message_ts`.
+- **Retention policy**: implicit, Redis maxmemory.
+- **Expected throughput**: **TBD**.

+
+## Dev Notes (Phase 1, 2026-06-27)
+
+**Status: shippable — verify gate green, working tree staged for leader commit.**
+
+### What shipped
+
+- `docker-compose.yml` (+267 lines): added `redis`, `mcp-server`, and 8 worker services. Container names carry the `lore-` prefix (host port remap 5434/7475/7688/9002/9003/8766/6379 to coexist with the damascus stack).
+- `plugins/nsc.py` (NEW, 291 lines): thin httpx proxy from the Python gateway to the Go `mcp-server`. Registers the 11 GraphMCP tools as MCP `tools/list` entries; `tools/call` JSON-RPC-passes through to the upstream.
+- `workers/` (NEW, 7 directories): ported `discord-connector`, `discord-filter`, `lore-watcher`, `ingestion-worker`, `entity-extractor`, `lore-extractor`, `encounter-processor`, plus `mcp-server`. Original Go module paths preserved (`github.com/graphmcp/...`).
+- `tests/contract/test_graphmcp_tool_contracts.py` (NEW, 15 tests): RED-then-GREEN. Asserts `tools/list` returns all 11 inherited tools, each carries the documented required fields, each accepts a valid payload and returns a structured MCP envelope, and validation rejects missing-required inputs.
+- `verify-merge.sh` (NEW): one-shot verify gate. 37 PASS / 0 FAIL.
+- `docs/VERIFICATION.md` (NEW): the Phase 1 verify-gate document.
+- `README.md` (+10 lines): updated service inventory (13 rows now, including the 8 workers) and the plugin list (nsc added).
+- `test.sh` (+1 line): default `GATEWAY` URL bumped `8765` → `8766` to match the host-side port remap.
+
+### Decisions taken
+
+1. **Worker port remap 8765 → 8766.** The damascus stack already binds 8765 on this host. The lore stack is on 8766. Updated `test.sh` default and all README curl examples. Verifier still accepts a `GATEWAY` env override for backward compatibility.
+2. **Expected services in `verify-merge.sh` use service names, not container names.** Service names in compose are unprefixed (`neo4j`, `gateway`, etc.); only `container_name` carries the `lore-` prefix. First version of the script conflated the two and falsely reported 12 failures.
+3. **nsc plugin as a single file, not a package.** The gateway's `load_plugins()` globs `*.py` in `plugins/`; a flat file matches. A future enhancement (out of Phase 1) can split nsc into a package once server.py learns `__init__.py` discovery — this is consistent with the existing plugin convention.
+4. **`discord-connector` runs but disables itself via `DISCORD_ENABLED=false`.** Per the ambiguity; the container restart-loops but doesn't consume Redis or Neo4j resources, and the verify gate ignores it.
+5. **Neo4j query in verifier returns 38 nodes** — matches the seeded lore-engine data; that proves both substrates coexist (legacy Person/Location/Faction/Encounter from seed.py + the inherited GraphMCP ontology).
+
+### Anything I couldn't do
+
+- **Did NOT run `git commit`.** Per the hard rules. Working tree is staged; leader (Hermes) commits.
+- **Did NOT push or open PR.** Both depend on the leader's commit. Branch `feat/p1-substrate-merge` is local-only at HEAD `c27adc6` + staged changes.
+- **`get_encounter` is exercised with a synthetic nonexistent id.** The contract assertion is envelope-shaped, not semantic. Real-world get_encounter behavior is downstream of Phase 1.
+
+### How to re-verify
+
+```bash
+cd /root/lore-engine-poc
+docker compose up -d --build
+bash verify-merge.sh        # 37 PASS / 0 FAIL
+bash test.sh                # no regression
+GATEWAY_URL=http://localhost:8766/mcp \
+  python3 -m pytest tests/contract/test_graphmcp_tool_contracts.py -v   # 15/15 pass

+
+### Status
+
+Branch `feat/p2-ontology-time-planes` prepared locally; **NOT** committed (per
+hard rule "DO NOT run `git commit`. The leader (Hermes) commits."). Leader
+needs to `git add -A && git commit && git push origin feat/p2-ontology-time-planes
+&& gh pr create` to ship this story.
+
+### Files changed (working tree)
+
+- `neo4j/init.cypher` — extended with Plane/Setting/EXISTS_IN/REFLECTS/LAYER_OF/ADJACENT_TO/ACCESSIBLE_VIA schema (29-line block at the bottom).
+- `scripts/migrate-to-v1.2.sh` — NEW (idempotent Cypher migration in 8 phases; uses heredoc + `docker exec cypher-shell` so the script doesn't need the Python driver on the host).
+- `plugins/world.py` — extended with `PLANE_AWARE_RELATION_ALLOWLIST` (adds `EXISTS_IN` + `PRACTICED_AT`), `entity_context` now surfaces `plane_relations`, NEW tool `entity_planes_at_time`.
+- `plugins/planes/__init__.py` — NEW (subpackage; exports `list_planes`, `entity_planes`, `entity_planes_at_time`, `find_plane_violations`).
+- `plugins/planes/cypher.py` — NEW (Cypher strings kept separate for readability).
+- `plugins/planes.py` — NEW shim (server.py uses `glob("*.py")` so it doesn't auto-load subpackages; this 12-line shim imports `plugins.planes` so the @REGISTRY.tool decorators fire).
+- `seed.py` — extended with `seed_planes_v1_2()` (called from `seed_neo4j` so a fresh `python3 seed.py` produces the v1.2 shape end-to-end, no migration step required).
+- `tests/test_plane_migration.py` — NEW (4 tests, all green).
+- `mock-data/manifest.json` — NEW (v1.2 dataset manifest).
+- `docs/VERIFICATION.md` — extended with Phase 2 verification recipe + AC checklist.

+### AC verification (extra evidence beyond the 4 named tests)
+
+End-to-end smoke tests through the gateway `:8766/mcp`:
+
+- `list_planes` returns 4 planes with their Setting + topology edges
+  (REFLECTS / LAYER_OF / ADJACENT_TO / ACCESSIBLE_VIA).
+- `entity_planes_at_time(Roland Raventhorne, 3rd_age.year_435, default)` →
+  `located_in: [mardonari.voldramir]` (after the year_420 transition).
+- `entity_planes_at_time(Roland Raventhorne, 3rd_age.year_415, default)` →
+  `located_in: [mardonari.material]` (before the transition).
+- `was_true_at(PRACTICED_AT, "Roland Raventhorne", "The Wheel & Kiln of Mardonar",
+  "3rd_age.year_435", default)` → `was_true: true`.
+- `was_true_at(PRACTICED_AT, "Roland Raventhorne", "The Wheel & Kiln of Mardonar",
+  "3rd_age.year_415", default)` → `was_true: false`.
+- `entity_context(Roland Raventhorne, default)` → `plane_relations` field
+  surfaces both `LOCATED_IN -> Material`, `LOCATED_IN -> Voldramir`, `EXISTS_IN -> Voldramir`.
+- `find_plane_violations` returns 15 missing_exists_in violations
+  (most Persons in the default seed pre-date the v1.2 model; follow-up to
+  add EXISTS_IN assertions to seed.py).
+- Tool count: 31 → 35 (4 new plane tools added).
+
+### Things the leader needs to do
+
+1. `git add -A && git commit -m "Phase 2: v1.2 plane migration + Setting/Plane ontology"`
+2. `git push origin feat/p2-ontology-time-planes`
+3. `gh pr create --base main --head feat/p2-ontology-time-planes --title "Phase 2 — v1.2 plane migration" --body-file <body>`
+4. Optionally: ship the PR body referencing this story file.
+
+### Notes / gotchas
+
+- **Duplicate `entity_planes_at_time` registration.** It's defined in both
+  `plugins/world.py` (per the story deliverable list, which explicitly puts
+  `entity_planes_at_time` in world.py) AND in `plugins/planes/__init__.py`
+  (also per the story). The registry is a `dict` keyed by name with last-write-wins;
+  `plugins/planes.py` sorts alphabetically before `plugins/world.py`, so the
+  planes/__init__.py version wins. Both implementations are equivalent in
+  semantics; the planes version is slightly more idiomatic because the
+  Cypher is in `plugins/planes/cypher.py`.
+- **Existing test files (`test_multi_world.py`, `test_consistency.py`, etc.)
+  use port 7687**, but the host Neo4j is on 7688 per docker-compose.yml.
+  This is a pre-existing issue (the tests fail with `Connection refused`
+  on the default port 7687) — out of File Scope. The story's test command
+  uses `bash test.sh` (which uses the gateway on :8766) and pytest against
+  `tests/test_plane_migration.py` only, both of which pass.
+- **`MULTIVERSE_COUNTERPART_OF` defensive cleanup.** Per Ambiguity §2,
+  the migration removes only the Roland↔Roland edges. The current graph
+  has 1 surviving `MULTIVERSE_COUNTERPART_OF` edge between non-Roland
+  nodes, logged by step [8/8] and left intact for manual review.

No further parents are linked. Note that **Yssa Raventhorne** is listed as a separate ancestor branch (the Raventhorne line), distinct from the Vyr patriline; I don't have a confirmed birth parent link between Yssa and Cael/Maric from this query, so the top of the tree is the Vyr line (Theron \u2192 Maric \u2192 Cael) plus the Raventhorne-line mother Yssa converging on Aldric.",

Here is the known ancestral chain, walking back as far as the graph records:\n\n| Generation | Ancestor | Born | Died | Edge to Aldric |\n|---|---|---|---|---|\n| 1 (parents) | **Cael Vyr** | 160 | 240 | PARENT_OF \u2192 Aldric |\n| 1 (parents) | **Yssa Raventhorne** | 165 | 300 | PARENT_OF \u2192 Aldric |\n| 2 (paternal) | **Maric Vyr** | 85 | \u2014 | PARENT_OF \u2192 Cael |\n| 3 (paternal) | **Theron Ashveil** | 10 | \u2014 | PARENT_OF \u2192 Maric |\n\nTheron Ashveil has no recorded parents, so he is the **founding root of House Vyr** as recorded in the world graph.\n\nA couple of notes worth flagging:\n- **Yssa Raventhorne** (Aldric's mother) carries the Raventhorne name but is *not* a member of the \"House Vyr (bloodline)\" lineage group in the graph \u2014 only Cael, Maric, Theron, and Aldric are. The Raventhorne surname therefore appears to enter the line through her rather than the Vyr paternal line.\n- The chain covers **4 generations** back from Aldric; nothing further exists for Theron Ashveil, so the graph cannot trace the line earlier than that.",

+PRD — Lore Engine × GraphMCP Substrate Merge
+
+> **Template**: BMAD PRD at `_bmad-output/meta/prd.md`. Companion to `planning-artifacts/architecture.md` and `meta/epics.md`.
+
+**Project**: `kaykayyali/lore-engine-poc` (runtime) — Gitea project: `lore-engine-merge`
+**Author**: hermes-agent (BMAD Phase 4 epic)
+**Date**: 2026-06-26
+**Status**: Draft v1 — pending architecture review gate
+**Companion ADR**: [[2026-06-26 Lore Engine GraphMCP Merge]] (Decision); [[2026-06-26 Lore Engine GraphMCP Merge Research]] (research)
+
+**Phase index** (linked stories):
+- **Phase 0** — Inventory of GraphMCP-Example substrate: [`docs/merge/00-inventory.md`](../docs/merge/00-inventory.md). *Gate story — nothing else ships until the inventory lands.*
+- Phase 1 — Substrate merge (deferred to story S2)
+- Phase 2 — Ontology + time planes (S3)
+- Phase 5 — Bot integration (S6)
+- Phase 6 — Connector template (S7)
+
+---
+
+## 1. Goal
+
+Produce a **single merged MCP runtime** that:
+
+- Hosts the 14-node lore ontology + time-bounded relations + v1.2 Setting/Plane model on top of GraphMCP-Example's existing Person/Location/Faction/Event/Encounter graph
+- Preserves all 7 GraphMCP ingestion workers (Go, Redis Streams) — they're proven, production, and the user has stated "I'll add more"
+- Adds 2 new Go workers (structured-ingestor + dialogue-processor) for the YAML/Dialogue paths that lore-engine designed but never shipped
+- Exposes a unified MCP tool surface (~24 tools): 8 inherited GraphMCP + 12 lore-engine POC plugins + 4 v1.2 plane tools + consistency generalizations
+- Lets `kaykayyali/mardonar-npcs` (the new Discord bot) call `query_as_npc` + `log_encounter` and publish NPC dialogue to `raw.dialogue`
+
+**The smallest end-state we can ship:** Phase 0 + Phase 1 + Phase 5 — the bot can run a Mardonar encounter and the NPCs remember across sessions via the merged MCP server, even without the v1.2 plane model or the consistency engine. Phases 2-4 and 6 are additive.
+
+**Repo destinations post-merge:**
+
+| Repo | Post-merge role |
+|---|---|
+| `kaykayyali/mardonar-specs` | YAML encounter corpus (content only, unchanged) |
+| `kaykayyali/mardonar-npcs` (NEW) | Discord bot runtime; consumes mardonar-specs at build time; calls the merged MCP server |
+| `kaykayyali/lore-engine` | Design docs (17 docs + ongoing). **Unchanged in this epic.** |
+| `kaykayyali/lore-engine-poc` | **Merged runtime home.** Gains Redis + 7 workers + 2 new workers + the merged MCP surface. |
+| `kaykayyali/GraphMCP-Example` | **Deprecated.** Once lore-engine-poc reaches feature parity, archive this repo (do NOT delete — historical value). |
+
+---
+
+## 2. Personas
+
+| Persona | What they want |
+|---|---|
+| **Kay (operator / DM)** | Author a new encounter in `mardonar-specs`, commit, rebuild bot image. The bot runs it. NPCs remember across sessions. The lore graph is consistent and historically accurate. |
+| **World-builder** | Write `timeline.yaml` / `family_tree.yaml` / `gazetteer.yaml` / `magic_system.yaml` and ingest via `POST /ingest/structured`. The graph updates deterministically (no LLM in the loop for structured facts). |
+| **LLM (LLM as DM)** | Open-ended world queries through MCP: "what did House Vyr rule in 340 TA?", "where is Roland currently?", "did Aldric witness the Battle of Black Spire?". Get precise, source-attributed, contradiction-checked answers. |
+| **NPC (in-character via bot)** | Be queried for what they personally know (`query_as_npc`). Their answers are scoped to WITNESSED edges. They remember across sessions. |
+| **Future ingestion source author (Slack connector, RSS feed, PDF watcher, etc.)** | Copy `connector-template/`, set the env vars, point at a stream. New workers appear in `docker compose ps` healthy. |
+
+---
+
+## 3. User Stories (v1)
+
+### P0 — must have for v1
+
+- **U1**: As Kay, I author a YAML encounter spec, commit it to `mardonar-specs`, and rebuild the bot image with `SPECS_GIT_URL`. The bot loads it and runs the encounter in Discord.
+- **U2**: As the LLM DM, I query the merged MCP server with `query_as_npc(name="Bram", question="what's my opening line?")` and get an answer scoped to Bram's WITNESSED-edge knowledge.
+- **U3**: As the bot, I call `log_encounter(title=..., participants=..., summary=..., location=...)` after each scene. The next `query_as_npc` returns this encounter in the NPC's witness graph.
+- **U4**: As Kay, I ask the MCP server "where was Roland Raventhorne in 430 TA?" and get a precise, time-bounded answer using `was_true_at`.
+- **U5**: As world-builder, I POST `timeline.yaml` to `/ingest/structured`. The graph gains Date/Event/Edge nodes within 1s; no LLM in the loop.
+- **U6**: As Kay, I open Neo4j Browser at `:7474` and inspect the merged graph — I see Settings, Planes, Persons, Factions, Eras, Encounters, LoreFragments with proper edges.
+
+### P1 — nice-to-have for v1
+
+- **U7**: As Kay, I run `verify-merge.sh` and it exercises every plugin and every inherited tool end-to-end (green).
+- **U8**: As Kay, I add a new ingestion source by copying `connector-template/`. New workers appear in `docker compose ps` healthy.
+- **U9**: As Kay, I ask "find contradictions about Aldric's whereabouts" and the consistency engine surfaces planted contradictions from the seed.
+- **U10**: As LLM DM, I ask "what plane is Roland on right now?" and get `entity_planes_at_time(Roland, "now")` → `mardonari.material`.
+
+### Out of scope for v1
+
+- **In-fiction physics** (dice rolls, combat resolution) — Foundry owns this; the bot calls into Foundry, not the lore engine.
+- **Plane-traversal mechanics** ("can I Plane Shift to Voldramir?") — the engine knows planes exist; it doesn't compute the spell.
+- **Real-time collaboration** — the bot is single-session, single-party. Multi-party concurrent sessions are v1.5.
+- **Voice/audio NPC dialogue** — text-only for v1. Audio is a v2 expansion.
+- **Auto-scaling workers** — single-instance per worker for v1. The dual-LLM arbitration pattern (`*-2` replicas) handles quality, not load.
+
+---
+
+## 4. Functional Requirements
+
+### 4.1 MCP server (the merged surface)
+
+The merged MCP server MUST expose at least these 24 tools:
+
+| Inherited from GraphMCP-Example (8) | Inherited from lore-engine-poc (12) | New from v1.2 plane model (4) |
+|---|---|---|
+| `semantic_search` | `entity_context` | `list_planes` |
+| `graph_traverse` | `was_true_at` | `entity_planes` |
+| `get_context` | `state_at` | `entity_planes_at_time` |
+| `get_person_profile` | `ancestors_of` | `find_plane_violations` |
+| `query_as_npc` | `descendants_of` | |
+| `log_encounter` | `lineage_of` | |
+| `get_unresolved` | `log_trade` | |
+| `get_contradictions` | `trades_by_buyer` | |
+| | `market_price` | |
+| | `register_image` | |
+| | `recall_images` | |
+| | `search_images_by_caption` | |
+| | `embed_images` | |
+| | `search_images_semantic` | |
+| | `find_contradictions` (was `get_contradictions`) | |
+| | `find_anachronisms` | |
+| | `find_ontology_violations` | |
+| | `find_orphans` | |
+
+**Generalization requirement:** `get_contradictions` from GraphMCP is REPLACED by `find_contradictions` from lore-engine-poc (which is a generalization — same `subject`/`limit` params, plus optional `since`/`severity` filters). All tool discovery surfaces show the new name. `get_contradictions` becomes an alias if any consumer still references it.
+
+### 4.2 Ingestion layer
+
+The runtime MUST run all 9 worker processes (7 inherited + 2 new) connected to the 4 (now 5) Redis Streams:
+
+| Stream | Producers | Consumers |
+|---|---|---|
+| `raw.discord` | `discord-connector` | `discord-filter` |
+| `raw.messages` | `discord-filter`, `ingestion-worker` (HTTP) | `entity-extractor`, `entity-extractor-2` |
+| `raw.lore` | `lore-watcher`, `ingestion-worker` (HTTP) | `lore-extractor`, `lore-extractor-2` |
+| `raw.encounters` | `discord-connector`, `ingestion-worker` (HTTP) | `encounter-processor`, `encounter-processor-2` |
+| `raw.structured` (NEW) | `ingestion-worker` (HTTP `/ingest/structured`) | `structured-ingestor` |
+| `raw.dialogue` (NEW) | `ingestion-worker` (HTTP `/ingest/dialogue`) | `dialogue-processor` |
+
+**Dual-LLM arbitration contract:** every `-extractor` has a `-2` replica in the same consumer group. They race on the same stream entry; both write to Neo4j with `source_lv: 1` / `source_lv: 2`. `find_contradictions` surfaces entries where `source_lv: 1` and `source_lv: 2` disagree on the same claim.
+
+### 4.3 Graph ontology
+
+The merged graph MUST support both legacy GraphMCP nodes (Person/Location/Faction/Event/Encounter/Chunk) and lore-engine ontology extensions (Era/Lineage/Calendar/Culture/Deity/MagicSystem/Spell/Language/Title/Artifact/Region/Plane/Setting) plus the temporal relations and the v1.2 plane model.
+
+**Migration contract:** existing lore-engine-poc data (2 Settings, 4 Planes, Roland Raventhorne, the seed) MUST be migrated to the v1.2 model without loss. Specifically: the 2 Roland `Person` nodes collapse to 1 with two `LOCATED_IN` edges, the `MULTIVERSE_COUNTERPART_OF` relation goes away, and the `world_id` string property is deprecated (still readable for backwards compat).
+
+### 4.4 Bot integration
+
+`mardonar-npcs` MUST:
+
+- Validate encounter specs against `EncounterSpecSchema` (Pydantic v2) at `/encounter start`
+- Call `query_as_npc(name, question)` before every NPC reply
+- Call `log_encounter(...)` synchronously on encounter resolve
+- Publish every in-character NPC line to `POST /ingest/dialogue`
+
+**Build contract:** `SPECS_GIT_URL` and `SPECS_GIT_REF` Docker build args clone `mardonar-specs` into `./specs/` at build time. The image is fully self-contained; no runtime fetch.
+
+---
+
+## 5. Non-Functional Requirements
+
+- **Cost:** total LLM cost ≤ $20 for the full Phase 0-6 epic at minimax-m3 rates. Comfortably within Ollama $100/mo + Gemini $20/day caps.
+- **Latency:** `query_as_npc` returns in <500ms p95 for encounter-scoped queries (NPC witness graph is small). `log_encounter` is synchronous and MUST complete in <200ms p95.
+- **Reliability:** `log_encounter` is the source of truth for NPC memory. Failure returns an error to the bot; the bot retries; the encounter graph is consistent. No silent data loss.
+- **Backward compatibility:** GraphMCP-Example's existing 8 MCP tools keep the same input/output contracts (no breaking schema changes). Lore-engine-poc's existing 12 plugins extend, not break, their surface.
+- **Observability:** every worker logs structured JSON with `worker`, `stream`, `group`, `msg_id`, `latency_ms` per consumed message. Logs land in Docker's JSON log driver; `docker compose logs` shows them.
+
+---
+
+## 6. Risks + Mitigations
+
+| Risk | Likelihood | Impact | Mitigation |
+|---|---|---|---|
+| Lore-engine-poc plugins break when GraphMCP worker writes hit Neo4j | Medium | High | Phase 1 includes `verify-merge.sh` that exercises every plugin against the merged stack before phase 2 starts |
+| WITNESSED-edge semantics drift when plane model lands | Medium | High | Spell out: `WITNESSED` is Person↔Encounter, NOT Person↔Plane; orthogonal | P2 |
+| Two-LLM arbitration writes conflicting nodes | Medium | Medium | Add `source_lv` property check in `find_contradictions` | P3 |
+| `world_id` → plane migration corrupts existing Mardonar data | Low | High | One-shot Cypher migration with rollback, run against v1.2 seed; 2 Roland nodes collapse to 1 with two `LOCATED_IN` | P2 |
+| Bot `log_encounter` writes fail during active DM | Low | High | Sync write is the contract; failure → bot retries; encounter graph is source of truth | P5 |
+
+---
+
+## 7. Phased execution (summary — full detail in `meta/epics.md`)
+
+| Phase | What | Owner profile | Wall clock | Cost |
+|---|---|---|---|---|
+| P0 | Inventory of GraphMCP workers/tools/streams | dev | 30 min | ~$0.40 |
+| P1 | Substrate merge (Redis + 7 workers + nsc plugin) | dev + tester | 2 h | ~$1.60 |
+| P2 | Ontology + time + planes | dev + tester | 2 h | ~$1.60 |
+| P3 | Consistency engine | dev + tester | 1.5 h | ~$1.20 |
+| P4 | Structured + dialogue ingestion | dev + tester | 2 h | ~$1.60 |
+| P5 | Bot integration (mardonar-npcs ↔ merged MCP) | dev + tester | 2 h | ~$1.60 |
+| P6 | Connector template + first new source | dev + tester | 1.5 h | ~$1.20 |
+| **Total** | | | **~11.5 h** | **~$9.20** |
+
+Linear chain P0 → P1 → ... → P6. P6 can fan out into multiple `connector-*` workers once the template ships.
+
+---
+

+## 4. Component boundaries (what each piece owns)
+
+| Component | Owns | Reads | Writes |
+|---|---|---|---|
+| **mardonar-bot** | Discord session lifecycle; LLM narration; name draws; in-world error messages | `query_as_npc(name, question)` from MCP; encounter spec from `./specs/` | `log_encounter(...)` to MCP (sync); `POST /ingest/dialogue` (async) |
+| **lore-gateway** | MCP JSON-RPC dispatch; plugin autoreload; `tools/list`; SSE sessions | Neo4j (bolt); Postgres (psycopg); MinIO (S3) | Neo4j (Cypher); Postgres (SQL); MinIO (S3 PUT) |
+| **workers/* (Go)** | Stream consumption; LLM extraction; dual-LLM arbitration; Cypher writes | Redis Streams; Neo4j | Redis Streams (XADD); Neo4j (Cypher) |
+| **ingestion-worker** | HTTP chunking + embedding; LLM-callable embedgemma | Redis Streams (XREADGROUP) | Neo4j (Chunk/LoreChunk) |

+| **connector-template (NEW)** | Canonical Go starter for any new producer | Environment (env-driven) | Redis Streams (XADD) |
+
+## 5. Data flow — a Mardonar encounter (end-to-end)
+
+```
+1. Kay commits `the-clock-maker.yaml` to mardonar-specs
+2. Rebuild mardonar-bot image: docker build --build-arg SPECS_GIT_URL=mardonar-specs .
+3. Bot loads spec at /app/specs/the-clock-maker.yaml; EncounterSpecSchema validates it
+4. Player triggers `/encounter start the-clock-maker` in Discord
+5. Bot calls mcp:query_as_npc(name="clockmaker", question="what's my opening line?")
+   → MCP gateway → nsc plugin → Neo4j Cypher:
+       MATCH (p:Person {name: $name})-[:WITNESSED]->(e:Encounter)-[:FEATURES]->(entity)
+       RETURN e, entity ORDER BY e.timestamp DESC LIMIT 5
+   → returns: previous encounters the clockmaker has witnessed
+6. Bot narrates opening scene (LLM-generated, persona-grounded)
+7. Player interacts → bot loops: query_as_npc → LLM narrate
+8. Each NPC line → POST /ingest/dialogue → ingestion-worker → XADD raw.dialogue
+9. Scene resolves → bot calls mcp:log_encounter(title, participants, summary, location)
+   → MCP gateway → nsc plugin → Neo4j Cypher:
+       MERGE (enc:Encounter {id: $id})
+       WITH enc
+       UNWIND $participants AS p_name
+       MATCH (p:Person {name: p_name})
+       MERGE (p)-[:WITNESSED]->(enc)
+       RETURN enc, count(*) as witnesses
+   → returns: encounter + witness count
+10. Next session, same NPC, same query_as_npc → returns the new encounter
+```
+
+## 6. Data flow — world-builder ingests a structured fact
+
+```
+1. World-builder writes timeline.yaml for "Battle of Black Spire"
+2. World-builder → POST /ingest/structured -F file=@timeline.yaml -F source_type=timeline
+3. ingestion-worker validates the multipart; XADD raw.structured with YAML body + source_type tag
+4. structured-ingestor (Go) consumes the entry:
+   a. Parses YAML (no LLM)
+   b. Validates against per-type schema (timeline.yaml vs family_tree.yaml vs gazetteer.yaml etc.)
+   c. Materializes Cypher:
+       MERGE (era:Era {id: $era_id}) SET era.name = $name, era.start_year = $start
+       MERGE (event:Event {id: $event_slug})
+         SET event.label = $label, event.in_fiction_date = $date, event.year = $year
+       MERGE (event)-[:OCCURRED_DURING]->(era)
+       MERGE (event)-[:OCCURRED_AT]->(:Location {id: $location_id})
+       WITH event
+       UNWIND $participants AS p_id
+       MATCH (p:Person {id: p_id})
+       MERGE (p)-[:PARTICIPATED_IN {valid_from: $date, valid_until: $date}]->(event)
+       RETURN event
+5. consistency-engine runs: find_anachronisms, find_plane_violations (no scheduled batch — runs on-demand)
+6. World-builder queries mcp:was_true_at(relation=PARTICIPATED_IN, subject="aldric_raventhorne", object="battle_of_black_spire", at_time="3rd_age.year_340")
+   → MCP gateway → world plugin → Neo4j Cypher → returns: was_true: true, sources: ["chronicles-vyr.md"]
+```
+
+## 7. Auth + access model
+
+- **No public ingress.** The merged MCP runtime is on `hp-grey-public.tailcb2b60.ts.net:8765` via Tailscale Serve. Tailnet-only.
+- **MCP server has no auth layer.** It's a private tailnet service. If we ever expose it externally, we add bearer auth (the lore-engine-poc gateway already has `Authorization: Bearer` plumbing from an earlier spike).
+- **Bot has DISCORD_TOKEN auth** to Discord. Bot-to-MCP traffic is on the trusted tailnet.
+- **Gitea API token** for the bot's `git push` workflow (if we ever make specs push hot-reload) — currently not implemented.
+
+## 8. Deploy plan
+
+| Step | Action |
+|---|---|
+| 1 | Phase N's PR merged to lore-engine-poc `main` |
+| 2 | `docker compose -f lore-engine-poc/docker-compose.yml up -d --build` |
+| 3 | Verify with `verify-merge.sh` (one per phase) |
+| 4 | Inspect Neo4j Browser at `:7474` for the new graph shape |
+| 5 | Curl `:8765/mcp` `tools/list` for the new tool surface |
+| 6 | Update wiki `Projects/Lore Engine.md` with the new state |
+| 7 | Update ADR with the merge SHA |
+
+**Per-phase** rebuild + verify is the cycle. The orchestrator handles the PR-merge-and-build on a 1m cron tick; the dev worker commits + opens the PR; the operator (me) merges after verify-gate is green.
+
+## 9. Backwards compatibility
+
+- **GraphMCP-Example tools:** the 8 inherited MCP tools keep their input/output contracts verbatim. `get_contradictions` becomes an alias for `find_contradictions` (the new generalized version) for one minor version, then `get_contradictions` is removed.
+- **lore-engine-poc plugins:** the existing 12 plugins extend, not break, their surface. New params are optional; old params keep their meaning.
+- **lore-engine-poc data:** the v1.2 plane migration is a one-shot Cypher script that adds Setting/Plane nodes, writes `EXISTS_IN`/`LOCATED_IN` edges, and collapses the 2 Roland nodes into 1. The script is idempotent — running it twice does nothing the second time.
+- **`world_id` string property:** deprecated but readable. New writes don't set it. Old reads still work for one minor version, then the property is dropped.
+- **`MULTIVERSE_COUNTERPART_OF` relation:** removed in the migration. The 2 Roland nodes are collapsed, so the relation has nothing to point to.
+
+## 10. Open questions for Kay
+
+1. **Phase 6 first new source:** Slack, RSS feed, Foundry CSV export, GitHub repo watcher, raw paste scraper, or something else? The canonical `connector-template/` is built around whichever you pick.
+2. **Plane taxonomy for non-Mardonari settings (v1.3):** Eberron already has data in the lore-engine-poc seed. Darksun, Forgotten Realms, homebrew settings — do we model them as full Settings or as ad-hoc Plane collections under a default `unknown` setting?
+3. **Bot's text-to-speech** (audio NPC dialogue) is explicitly out-of-scope for v1. If you want to ship v1 with audio, we add it as a v1.1 epic.
+4. **Multi-party concurrent sessions** (multiple Discord sessions running the same bot at once, with shared encounter state) is explicitly out-of-scope for v1. v1.5 if you want it.
+
+## 11. Verification
+
+Per [[Verify Gate]], every shipped phase ships with `verify-merge.sh` + `docs/VERIFICATION.md`. The final rolled-up verify-gate at end-of-epic:
+
+```bash
+#!/usr/bin/env bash
+# verify-merge.sh — exercises every plugin + every inherited tool
+set -euo pipefail
+
+cd /root/lore-engine-poc
+
+# 1. All 11 services healthy
+docker compose ps --services | xargs -I{} docker compose ps {} | grep -E "Up|healthy" || exit 1
+
+# 2. Plugin tool surface complete (24 tools)
+TOOL_COUNT=$(curl -s -X POST http://localhost:8765/mcp \
+  -H 'Content-Type: application/json' \
+  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' \
+  | python3 -c "import json,sys; print(len(json.load(sys.stdin)['result']['tools']))")
+[ "$TOOL_COUNT" -ge 24 ] || { echo "FAIL: only $TOOL_COUNT tools"; exit 1; }
+
+# 3. Neo4j has merged ontology
+NEO4J=$(docker exec lore-neo4j cypher-shell -u neo4j -p lore-d...n -d neo4j)
+echo "$NEO4J" "MATCH (n) WHERE n:Plane OR n:Setting RETURN count(n)" | grep -E "^[0-9]+$" || exit 1
+
+# 4. Lore-engine-poc tests green
+bash test.sh
+
+# 5. LLM consumer E2E green
+bash examples/run_questions.sh
+
+# 6. Bot integration E2E (Phase 5 onwards)
+bash /root/mardonar-npcs/tests/test_bot_encounter.sh

+nsc plugin — thin httpx proxy to the Go mcp-server.
+
+The lore-engine-poc gateway exposes MCP tools by importing Python plugin
+files from /app/plugins. The 11 GraphMCP-Example tools (semantic_search,
+graph_traverse, get_context, get_person_profile, query_as_npc,
+log_encounter, get_unresolved, get_contradictions, list_encounters,
+search_encounters, get_encounter) live in a Go service (`lore-mcp-server`
+on port 9000) and speak JSON-RPC over HTTP at `/mcp`.
+
+Per the Phase 1 ambiguity ("workers stay Go, gateway stays Python"):
+this plugin is a thin proxy that translates the gateway's JSON-RPC
+into the upstream call and surfaces the tools via the gateway's
+`tools/list`. The handler dispatches `tools/call` to the upstream
+mcp-server and returns the parsed result.
+
+Configuration (env):
+  NSC_MCP_URL  — default `http://mcp-server:9000`
+
+Note on plugin shape: lore-engine-poc's existing plugins live as flat
+files in /app/plugins (see server.py load_plugins glob("*.py")). The
+nsc plugin follows that convention — one file, one register() entry
+point. A future enhancement (out of Phase 1 scope) could split nsc
+into a package directory once server.py learns to discover __init__.py.

+The 11 GraphMCP-Example MCP tools (`semantic_search`, `graph_traverse`,
+`get_context`, `get_person_profile`, `query_as_npc`, `log_encounter`,
+`get_unresolved`, `get_contradictions`, `list_encounters`,
+`search_encounters`, `get_encounter`) must be exposed through the
+lore-engine-poc gateway with their original input/output contracts intact.
+
+The Phase 1 verify-gate is: `bash verify-merge.sh` exercises each tool
+through the Python gateway → nsc plugin → Go mcp-server path; this test
+exercises the same tool surface from pytest using a JSON-RPC client
+directly to the gateway.
+
+The test is contract-level only:
+- Tools are listed by `tools/list` with the exact name + required field set.
+- Each tool accepts the documented input schema and returns the
+  documented output shape (parsed as JSON if non-empty).
+- `isError: false` on success.
+
+It does NOT assert the content of LLM responses or Cypher results —
+that's covered by the per-tool integration tests downstream of Phase 1.

+
+Entity types (use exactly these labels):
+  Person    — a named character, player character, NPC, deity, or historical figure in the story
+  Location  — a named place, dungeon, city, region, landmark, or realm in the game world
+  Event     — a named battle, encounter, ceremony, quest milestone, or significant occurrence
+  Faction   — a guild, kingdom, order, cult, party, or named group of people
+  Item      — a named weapon, artifact, magical item, relic, or significant object
+  Creature  — a named or typed monster, beast, or non-person entity (e.g. "Ancient Red Dragon", "The Pale Worm")
+
+Relation types (use exactly these labels):
+  PARTICIPATED_IN — Person or Faction took part in an Event
+  OCCURRED_AT     — Event took place at a Location
+  LOCATED_AT      — Person, Faction, or Item is currently at or in a Location
+  RULES           — Person or Faction governs or controls a Location or Faction
+  MEMBER_OF       — Person belongs to a Faction
+  ALLIED_WITH     — Person or Faction is allied with another Person or Faction
+  ENEMY_OF        — Person or Faction is opposed to another Person or Faction
+  POSSESSES       — Person or Faction holds or owns an Item
+  SEEKS           — Person or Faction is actively looking for a Person, Item, or Location
+  KNOWS           — two Persons have a relationship or acquaintance
+  RELATED_TO      — two entities are connected but no specific relation applies
+
+Rules:
+- Always include the message author as a Person entity.
+- Use proper nouns only — do not extract generic words like "sword" or "city", only named ones.
+- Normalise names to title case (e.g. "theron" → "Theron Ashveil" if the full name is known from context).
+- Omit entities or relations you are not confident about.
+- If the message is out-of-character (e.g. rules questions, scheduling, meta discussion), extract no entities and return {"entities": [], "relations": []}.`

+  Item      — a named weapon, artifact, magical item, relic, or significant object
+  Creature  — a named or typed monster, beast, or non-person entity (e.g. "Ancient Red Dragon", "The Pale Worm")
+
+Relation types (use exactly these labels):
+  PARTICIPATED_IN — Person or Faction took part in an Event
+  OCCURRED_AT     — Event took place at a Location
+  LOCATED_AT      — Person, Faction, Item, or Creature is found at or in a Location
+  RULES           — Person or Faction governs or controls a Location or Faction

+  KNOWS           — two Persons have a relationship or acquaintance
+  PRECEDED        — this Event preceded another Event chronologically
+  CREATED_BY      — Item or Location was made or founded by a Person or Faction
+
+Rules:
+- Only extract entities that are explicitly named in the text.
+- Choose the most specific relation type that fits; omit a relation rather than guessing.
+- Omit entities or relations you are not confident about.
+- Do not invent names or relationships not present in the text.
+- temporal_hint: for every Event entity this field is REQUIRED. Use the best time information available in the text — a calendar year, a named age, a relative phrase like "shortly after the Fall of Thornwall", or "sometime during the Dusk War". Write "unknown era" only as an absolute last resort. For non-Event entities include temporal_hint only when the text explicitly states when they were active, founded, created, or died.`
