+# ATDD Checklist — GraphMCP Live Integration Tests
+
+**Date:** 2026-06-19
+**Author:** TEA Agent (no BMad config in this repo — running on skill defaults)
+**Primary Test Level:** Integration (live infrastructure: real Discord gateway + real LLM + real GraphMCP + real Redis)
+
+---
+
+## Story Summary
+
+A live-infrastructure integration test suite that runs a real Mardonar encounter end-to-end against a running GraphMCP backend and verifies the slash-command outputs, skill-check tooling, and lore/question-answering paths that interface with the real graph database.
+
+**As a** Mardonar maintainer
+**I want** an integration suite that exercises the real GraphMCP backend (and real Discord + real LLM + real Redis) through the bot's encounter flow
+**So that** regressions in the GraphMCP contract, encounter lifecycle, skill-check tools, and lore/event-logging paths are caught before they reach players — including the wrong-shape-response crash class recently fixed in `src/graphmcp/client.ts`.
+
+---
+
+## Acceptance Criteria
+
+1. **AC1 — GraphMCP connectivity & JSON-RPC contract.** Given a reachable GraphMCP endpoint (`GRAPHMCP_URL`), when the suite invokes each JSON-RPC tool (`query_as_npc`, `semantic_search`, `log_encounter`, `list_encounters`, `search_encounters`, `get_encounter`), then each returns a payload matching its declared TypeScript contract in `src/graphmcp/client.ts`, and wrong-shape success responses (missing/null `chunks`, non-array encounter lists, bare arrays) are normalized — never crash callers with `Cannot read properties of undefined (reading 'length')`.
+
+2. **AC2 — Real encounter lifecycle via slash commands.** Given the bot connected to the real Discord gateway with real Redis + GraphMCP + LLM, when the suite drives `/encounter start` (hybrid: `execute()` with a fake interaction backed by real channel objects from the live client), then a thread is created, the opening narrative is posted to Discord, and a `SessionState` is persisted in Redis; when a driver bot posts a chat message and the LLM responds, the turn flows through `messageRouter` → `callLLM` → `toolDispatcher` and session history updates; when `/encounter end` runs, the encounter resolves, a summary is written, `log_encounter` commits to GraphMCP, and the thread archives.
+
+3. **AC3 — Skill-check tool.** Given an active encounter, when the LLM emits a `skill_check_emit` tool call, then a skill-check embed is posted to the thread and `pendingSkillCheck` is set in session state; when the roll resolves via `foundry_lookup`/`foundry_reward`, then the outcome is recorded and `pendingSkillCheck` is cleared.
+
+4. **AC4 — Lore/question answering + event read-after-write.** Given real lore in the graph, when a player @mentions the bot or asks a question that triggers `context_recall`/`semantic_search`, then the answer references real lore retrieved from the graph; when `log_encounter` writes an event, then `list_encounters`/`search_encounters` return that event afterward (read-after-write consistency).
+
+5. **AC5 — Long encounter (20–30 turns) with complex skill usage, varied goal outcomes, and final-output verification.** Given an active run-tagged encounter, when the suite drives 20–30 turns through the real scheduler (`scheduleEncounterLLMTurn` + history polling) with a scripted driver strategy, resolving every `skill_check_emit` via `handleRollInteraction`, then the encounter reaches a valid goal outcome (one of the spec's `goals.primary`/`secondary` ids) within the turn cap; different driver strategies reach DIFFERENT goal outcomes; and the final `encounter_resolve` output is read back from GraphMCP (`list_encounters` matched by run-id in the title → `get_encounter` returns the LLM-written summary, participants, and the resolved `outcomeId` in the title).

+## Story Integration Metadata
+
+- **Story ID:** `graphmcp.live.1`
+- **Story Key:** `graphmcp-live-integration-tests`
+- **Story File:** (user-provided goal — no BMad story file in this repo)
+- **Checklist Path:** `tests/integration/atdd-checklist-graphmcp-live-integration-tests.md`
+- **Generated Test Files:** _(populated in step 4)_
+
+> No writable BMad story file exists in this repo (`_bmad/` is absent), so the BMM `dev-story` handoff step does not apply. This checklist is the handoff artifact.
+
+---
+
+## Generation Mode
+
+**Mode:** AI generation (from source code + the GraphMCP client contract in `src/graphmcp/client.ts` + existing `tests/integration/phase1.test.ts` patterns).
+
+**Reason:** `detected_stack = backend` — recording mode is skipped entirely for backend projects (no browser/UI). Tests are generated from API/source analysis, not browser recording.
+
+---
+
+## Test Strategy Decisions (confirmed with user)
+
+- **Discord surface:** Real connected bot on the real gateway. Slash commands (`/encounter start`, `/encounter end`) are driven via the **hybrid** pattern — call the registered command's `execute()` with a fake `ChatInputCommandInteraction` whose `channel`/`guildId`/`user` are **real `discord.js` objects fetched from the live client** (real `TextChannel`/thread from a test guild). Thread creation, message posting, and replies flow through the real gateway to real Discord; only the command "click" is synthesized. (Bots cannot invoke each other's slash commands via the Discord API, so pure gateway-driven slash commands are not automatable.)
+- **Thread conversation turns:** A **driver bot** (separate token) posts real chat messages into the encounter thread, firing the real `messageRouter` path through the live gateway.
+- **LLM:** Always real (LiteLLM primary → Ollama fallback). Assert on **structural outcomes** (session-state fields, embed presence, GraphMCP query results), never exact narrative text. Use polling/retries for LLM-turn completion and graph read-after-write (eventual consistency).
+- **Stack:** `backend` (Node/TypeScript, `discord.js`, Vitest, `environment: 'node'`, `globals: true`). No Playwright/Cypress/Pact — all TEA utils flags default to disabled.
+- **Gating:** Skip unless `RUN_FULL_E2E=1` (stricter than the existing `RUN_INTEGRATION=1`, because this suite exercises real Discord + real LLM and is slow/non-deterministic). Follow the existing `describe.skipIf(...)` pattern from `tests/integration/phase1.test.ts`.
+
+---
+
+## Operational Requirements (prerequisites to run this suite)
+
+- A dedicated **Discord test guild** (not a production server).
+- **Bot under test** credentials: `DISCORD_TOKEN`, `DISCORD_CLIENT_ID`, with `DISCORD_ALLOWED_CHANNELS` including the test channel and `DISCORD_ALLOWED_USERS` including the driver (or empty for channel-scoped).
+- A **second driver-bot token** for posting chat messages into threads.
+- **Redis** reachable at `REDIS_URL` (flush test keys between runs).
+- **GraphMCP** reachable at `GRAPHMCP_URL` (the real backend under test).
+- **LiteLLM** at `LITELLM_BASE_URL` and/or **Ollama** at `OLLAMA_BASE_URL` (real LLM).
+- All four up before running; `RUN_FULL_E2E=1` to activate.
+
+**Cleanup discipline:** unique `encounterId` prefix per run (e.g. `e2e-<timestamp>-…`) to avoid collisions; delete test threads; flush Redis test keys; tear down / tag GraphMCP test entities so the graph stays clean across runs.
+
+---
+
+## Red-Phase Test Scaffolds Created
+
+All scaffolds are real `it()` tests under `describe.skipIf(...)` — skipped without live infra (CI-safe), activated by env gates. Transpiled and verified to skip cleanly (see Test Execution Evidence). No `it.skip()` placeholders; each has concrete assertion intent.
+
+### Files generated (step 4 — sequential mode; no BMad subagent runtime present, E2E worker N/A for backend)
+
+| File | AC | Gate | Tests |
+|------|----|------|-------|
+| `tests/integration/graphmcp/contract.test.ts` | AC1 | `RUN_GRAPHMCP_LIVE=1` ∥ `RUN_FULL_E2E=1` | 7 (S1.1 skipIf no `E2E_TEST_NPC`) |
+| `tests/integration/graphmcp/encounter-lifecycle.test.ts` | AC2 | `RUN_FULL_E2E=1` | 3 (S2.1 start, S2.2 driver turn, S2.3 end) |

+| `tests/integration/graphmcp/support/poll.ts` | — | — | `waitFor` / `untilStable` (eventual-consistency + LLM-turn polling) |
+| `tests/integration/graphmcp/support/factories.ts` | — | — | `runId`, `buildEncounterLog`, `titleMatchesRun` |
+| `tests/integration/graphmcp/support/fakes.ts` | — | — | `fakeInteraction` (hybrid slash-command), `fakeButton` (roll-resolve drive), `parseThreadIdFromReply` |
+| `tests/integration/graphmcp/support/liveBots.ts` | — | — | `connectLiveBots` / `disconnectLiveBots` (real bot + driver bot clients) |
+| `tests/integration/graphmcp/support/cleanup.ts` | — | — | `deleteThread`, `flushRedisForGuild`, `disconnectRedis`; GraphMCP no-delete limitation noted |
+
+### Concrete vs scaffold (honest split)
+
+- **AC1 (contract)** — fully concrete and runnable against **live GraphMCP alone** (no Discord, no LLM, no Redis). Asserts the live server returns contract-shaped data the client accepts without crashing. The wrong-shape *normalization* itself is unit-tested with fetch mocks in `tests/unit/graphmcpClient.test.ts` (already green); here we assert live-contract conformance. S1.7 (bogus id) asserts no unhandled exception escapes — the `/encounter generate` crash was an unhandled `TypeError`, not a clean rejection.
+- **AC2 (lifecycle)** — S2.1 (start) and S2.3 (end) are concrete via the hybrid `execute()` + real channel/thread pattern. S2.2 (driver-message turn) routes the real fetched message through `messageRouter.handleMessage`; one explicit TODO marks the choice between direct router call vs. arming the full `src/bot/index.ts` messageCreate handler.
+- **AC3 (skill-check)** — driven **deterministically** (not by waiting for the LLM to emit): `skill_check_emit` handler invoked directly, roll resolution driven via `handleRollInteraction` + a fake `ButtonInteraction` targeting the posted embed. Concretely automatable; no LLM dependency for the emit/resolve steps (resolution schedules a real LLM turn afterward).
+- **AC4 (lore)** — S4.1 uses the hybrid `handleMention(realMentionMsg, botClient)` approach; asserts a bot reply is posted (structural) with a soft/manual TODO for asserting cited lore content (LLM output is non-deterministic). S4.2 read-after-write is fully concrete (poll `list_encounters`/`search_encounters`).
+
+### Gate refinement vs step 3
+
+Step 3 gated everything under `RUN_FULL_E2E=1`. Step 4 splits the gate: AC1 (contract) also activates under the lighter `RUN_GRAPHMCP_LIVE=1`, since it needs only GraphMCP — a maintainer can run the contract suite without spinning up Discord/LLM/Redis. AC2–AC4 remain `RUN_FULL_E2E=1` only. This is an improvement; the "Running Tests" section below is updated accordingly.
+
+---
+
+## Test Strategy (AC → scenarios → levels → priorities)
+
+`detected_stack = backend` → levels are **Integration** and **Integration/Contract** (no E2E/browser, no Component). All scenarios are gated by `RUN_FULL_E2E=1` (skipped otherwise).
+
+**Priority legend:** P0 = guards a real production crash / data integrity; P1 = core live-flow correctness (needs real LLM, slow); P2 = edge/negative.
+
+### AC1 — GraphMCP contract (Integration/Contract) — **P0**
+
+_File:_ `tests/integration/graphmcp/contract.test.ts` (no LLM needed; fastest live tests)
+
+| ID | Scenario | Level | Pri | Red expectation |
+|----|----------|-------|-----|-----------------|
+| S1.1 | `query_as_npc` returns `NPCQueryResult` (npc, tier, horizon_count, chunks[], graph_context[]) | Contract | P0 | Would have failed before client normalization; passes now |
+| S1.2 | `semantic_search` with wrong-shape response (`{chunks:null}`, no `chunks`, bare array) normalizes to `{chunks:[]}` — **regression for the `/encounter generate` crash** | Contract | P0 | Red before the `src/graphmcp/client.ts` fix; green after |
+| S1.3 | `log_encounter` returns `LogEncounterResult` (enc_id, title, participants, location, timestamp) | Contract | P0 | Structural assertion |
+| S1.4 | `list_encounters` returns `EncounterResultItem[]`; non-array response normalized to `[]` | Contract | P0 | Red before fix; green after |
+| S1.5 | `search_encounters` returns array; non-array normalized | Contract | P1 | Structural assertion |
+| S1.6 | `get_encounter` returns `EncounterDetails` shape | Contract | P1 | Structural assertion |
+| S1.7 | GraphMCP HTTP error / unreachable → `callTool` rejects and caller `.catch` degrades gracefully (no throw escapes) | Contract | P2 | Negative path |
+
+### AC2 — Real encounter lifecycle (Integration, real LLM) — **P1**
+
+_File:_ `tests/integration/graphmcp/encounter-lifecycle.test.ts`
+
+| ID | Scenario | Level | Pri |
+|----|----------|-------|-----|
+| S2.1 | `/encounter start` (hybrid `execute()` + real channel) creates a real thread, posts opening narrative, persists `SessionState` in Redis | Integration | P1 |
+| S2.2 | Driver bot posts a chat message → LLM turn runs → session history grows by the assistant turn (poll for completion) | Integration | P1 |
+| S2.3 | `/encounter end` resolves, writes summary file, `log_encounter` commits to GraphMCP (read-after-write via `list_encounters`), thread archives | Integration | P1 |
+
+### AC3 — Skill-check tool (Integration, real LLM) — **P1**
+
+_File:_ `tests/integration/graphmcp/skill-check.test.ts`
+
+| ID | Scenario | Level | Pri |
+|----|----------|-------|-----|
+| S3.1 | LLM-emitted `skill_check_emit` posts the skill-check embed + sets `pendingSkillCheck` in session (poll for embed/state) | Integration | P1 |
+| S3.2 | Roll resolves the check via `foundry_lookup`/`foundry_reward` → `pendingSkillCheck` cleared, outcome recorded | Integration | P1 |
+
+### AC4 — Lore/question answering + event read-after-write (Integration, real LLM) — **P1**
+
+_File:_ `tests/integration/graphmcp/lore-and-events.test.ts`
+
+| ID | Scenario | Level | Pri |
+|----|----------|-------|-----|
+| S4.1 | @mention / question triggers `context_recall`/`semantic_search`; an answer embed is produced referencing real graph lore (structural assert) | Integration | P1 |
+| S4.2 | `log_encounter` write is readable by `list_encounters`/`search_encounters` afterward (poll for read-after-write consistency) | Integration | P1 |
+
+### Planned support files (step 4)
+
+- `tests/integration/graphmcp/support/liveBot.ts` — real connected `Client` fixture + teardown.
+- `tests/integration/graphmcp/support/driverBot.ts` — second bot that posts chat messages into threads.
+- `tests/integration/graphmcp/support/fakes.ts` — `fakeInteraction` (backed by real channel/user objects), `fakeMessage` factories.
+- `tests/integration/graphmcp/support/factories.ts` — `createE2ESpec` (unique `encounterId` per run), `createSessionOverrides`.
+- `tests/integration/graphmcp/support/cleanup.ts` — Redis test-key flush, thread delete, GraphMCP test-entity teardown.
+- `tests/integration/graphmcp/support/poll.ts` — retry/poll helpers (LLM turn completion, graph read-after-write).
+
+### Red-phase note (adapted)
+
+Classic ATDD targets new features (red before implementation). This story's "implementation" is the test suite + support code against **existing** production behavior. Adaptation: scaffolds are real `it()` tests under `describe.skipIf(process.env.RUN_FULL_E2E !== '1')` — skipped without infra (CI-safe). When activated against live infra, passing = behavior holds; failing = a real regression. The **AC1** scaffolds are genuinely red→green: S1.2/S1.4 would have failed before the `src/graphmcp/client.ts` normalization fix and pass after it. AC2–AC4 require live Discord+LLM and are scaffolded with concrete assertion intent + polling, to be confirmed against a running stack.
+
+---
+
+## Data Factories Created
+
+`tests/integration/graphmcp/support/factories.ts`:
+
+- `runId()` → `e2e-<timestamp>-<pid>` — unique per run, used to tag every entity so runs never collide with each other or with real data.
+- `buildEncounterLog(run, overrides)` → `LogEncounterParams` with a `[E2E] <run> —` title prefix (what `list_encounters`/`search_encounters` filter on for read-after-write + cleanup identification).
+- `titleMatchesRun(run)` → predicate matching a title against this run's tag.
+
+`tests/integration/graphmcp/support/fakes.ts`:
+
+- `fakeInteraction(opts)` → `{ interaction, replies, edits, lastText }` — fake `ChatInputCommandInteraction` backed by a **real** `TextChannel`/`ThreadChannel`; captures `reply`/`editReply`, implements exactly the subset `encounter.execute()` reads (`guildId`, `channelId`, `channel`, `user`, `options.getSubcommand`/`getString`, `deferReply`/`editReply`/`reply`).
+- `fakeButton(channel, customId)` → fake `ButtonInteraction` for driving `handleRollInteraction` (roll-resolution path) — `channel` is the real thread, `update` captured.
+- `parseThreadIdFromReply(text)` → extracts `<#id>` from the `/encounter start` editReply.
+
+No `fakeMessage` factory was needed: conversation turns (S2.2, S4.1) fetch **real** `Message` objects posted by the driver bot rather than synthesizing them, per the hybrid pattern.
+
+---
+
+## Fixtures Created
+
+- **Live bots** (`support/liveBots.ts`): `connectLiveBots()` logs in a real `Client` for the bot under test (`DISCORD_TOKEN`) and a second driver bot (`E2E_DRIVER_TOKEN`), resolves the real `Guild` + `TextChannel` (`E2E_TEST_GUILD_ID` / `E2E_TEST_CHANNEL_ID`); `disconnectLiveBots()` tears both down. Used by AC2/AC3/AC4 `beforeAll`/`afterAll`.
+- **Redis** (`support/cleanup.ts`): `flushRedisForGuild(guildId)` deletes only this guild's `session:*` and `players:<guild>` keys (never `FLUSHDB`); `disconnectRedis()` closes the shared singleton so the process exits.
+- **Thread cleanup** (`support/cleanup.ts`): `deleteThread(channel, threadId)` best-effort deletes the run's encounter thread (ignores already-deleted).
+- **Poll helpers** (`support/poll.ts`): `waitFor`/`untilStable` with configurable timeouts — the fixture for eventual-consistency reads and LLM-turn completion.
+- **Env bootstrap** (`support/env.ts`): imported first by every test so `EnvSchema.parse` doesn't crash without real Discord creds; seeds `DISCORD_ALLOWED_CHANNELS` from `E2E_TEST_CHANNEL_ID`.
+
+No Vitest `test.extend` fixtures used — the project's integration pattern (per `tests/integration/phase1.test.ts`) is plain `describe.skipIf` + `beforeAll`/`afterAll` with dynamic/real imports, which these scaffolds follow for consistency.
+
+---
+
+## Mock Requirements
+
+**None for the "real" path.** This suite deliberately exercises real services (Discord gateway, LLM, GraphMCP, Redis). No HTTP mocks. (If a future opt-in "fast" variant stubs the LLM, that will be documented here.)
+
+---
+
+## Required data-testid Attributes
+
+**N/A** — backend integration suite; no DOM/UI. (Section retained from template for structural parity only.)
+
+---
+
+## Implementation Checklist
+
+Each scaffolded test → the concrete activation task(s) that make it pass against live infra. "Skip-clean" (transpiles + skips when gated off) is **done** for all; "live-pass" requires the listed infra.
+
+- **AC1 / contract.test.ts** —
+  - S1.1: set `E2E_TEST_NPC` to a real NPC name in the graph. *(infra: GraphMCP)*
+  - S1.2–S1.6: GraphMCP up at `GRAPHMCP_URL`; no other infra. *(infra: GraphMCP)*
+  - S1.7: GraphMCP up; bogus-id behavior is whatever the live server returns (assertion is only "no unhandled throw escapes"). *(infra: GraphMCP)*
+  - Activation: `RUN_GRAPHMCP_LIVE=1 npx vitest run tests/integration/graphmcp/contract.test.ts`
+- **AC2 / encounter-lifecycle.test.ts** —
+  - S2.1: set `DISCORD_TOKEN`, `E2E_DRIVER_TOKEN`, `E2E_TEST_GUILD_ID`, `E2E_TEST_CHANNEL_ID`, `E2E_SPEC` (default `market-thief`); Redis + GraphMCP + LLM up. *(infra: all four)*
+  - S2.2: **TODO to finalize** — confirm direct `handleMessage(realMsg, botClient)` is sufficient vs. arming the full `src/bot/index.ts` `messageCreate` handler; the under-test bot's messageCreate path must route the driver's thread message into `messageRouter`. *(infra: all four)*
+  - S2.3: same env as S2.1; `log_encounter` from `/encounter end` must be readable via `list_encounters` (poll for read-after-write). *(infra: all four)*
+- **AC3 / skill-check.test.ts** —
+  - Side-effect import `src/harness/tools/index.js` added so `getPlugin('skill_check_emit')` resolves without going through `toolDispatcher`.
+  - S3.1: invoke the plugin handler directly with a real thread + session; assert `pendingSkillCheck` persisted + embed message exists. *(infra: Discord + Redis; GraphMCP for the encounter start that creates the session)*
+  - S3.2: `fakeButton(thread, 'sc_roll')` → `handleRollInteraction`; assert `pendingSkillCheck` cleared + `[SKILL CHECK RESULT]` system message in history. *(infra: Discord + Redis; resolution schedules a real LLM turn afterward)*
+- **AC4 / lore-and-events.test.ts** —
+  - S4.1: `persona.yaml` present (`PERSONA_PATH`), Redis up (ingest stream via `publishToGraphMCP`), GraphMCP + LLM up. Driver bot @mentions the under-test bot in the test channel; reply is fetched via the under-test client. **Soft TODO**: asserting the reply cites specific lore stays manual (LLM non-determinism). *(infra: all four)*
+  - S4.2: GraphMCP only; poll `list_encounters` + `search_encounters` for the just-logged `[E2E]` event. *(infra: GraphMCP)*
+- **Cleanup** — `deleteThread` + `flushRedisForGuild` + `disconnectRedis` wired in `afterAll` of AC2/AC3/AC4. GraphMCP test encounters are `[E2E]`-prefixed and **not** deleted (no delete tool in `src/graphmcp/client.ts`); see `support/cleanup.ts` `GRAPHMCP_CLEANUP_LIMITATION`. A future `delete_encounter` tool would close this.
+
+### Verification done in step 5
+
+- ✅ `npx vitest run tests/integration` with no env → **5 files / 16 tests skipped**, exit 0 (CI-safe). Scaffolds transpile cleanly (esbuild would fail on syntax errors).
+- ✅ `npx vitest run tests/unit` → **33 files / 400 tests pass** — including the `graphmcpClient.test.ts` wrong-shape normalization regressions (S1.2/S1.4 unit-side guard for the `/encounter generate` crash) and `historyTrim.test.ts` FIFO test.
+- ⬜ Live-pass against real infra — **not run here**: the maintainer must provision the test guild, two bot tokens, Redis, GraphMCP, and LLM, then run `RUN_FULL_E2E=1` (and optionally `RUN_GRAPHMCP_LIVE=1` for AC1 alone). I cannot provision those services from this session.
+
+---
+
+## Running Tests
+
+```bash
+# AC1 only — needs just a reachable GraphMCP (fastest live checks)
+RUN_GRAPHMCP_LIVE=1 npx vitest run tests/integration/graphmcp/contract.test.ts
+
+# Full live suite (all four infra surfaces must be up)
+RUN_FULL_E2E=1 npm run test:int
+
+# A single file
+RUN_FULL_E2E=1 npx vitest run tests/integration/graphmcp/encounter-lifecycle.test.ts
+
+# CI default (the live suites stay skipped — no live infra in CI)
+npm run test:unit
+```
+
+> These tests are **not** part of the CI default (`npm run test:unit`). They are opt-in, run manually or from a dedicated burn-in job, per `ci-burn-in.md`. With no env gate set, `npm run test:int` skips all 16 graphmcp tests (and the 2 existing `phase1` tests) and exits 0 — verified in step 5.

+
+## Red-Green-Refactor Workflow
+
+_(Standard ATDD cycle — see template. RED phase scaffolds are produced in step 4; GREEN/REFACTOR are dev-team next steps.)_
+
+---
+
+## Knowledge Base References Applied
+
+This ATDD workflow consulted the following knowledge fragments (backend profile, TEA utils disabled):
+
+- **data-factories.md** — factory functions with overrides, API/DB seeding, cleanup discipline (applied: unique `encounterId`, session/interaction/message factories).
+- **component-tdd.md** — red→green→refactor loop, provider isolation.
+- **test-quality.md** — determinism, isolation, one-assertion-per-test DoD, execution limits (applied: assert structural outcomes, not LLM narrative text; generous timeouts for real LLM).
+- **test-healing-patterns.md** — common failure patterns and automated fixes (applied: polling for read-after-write, retries for LLM turn completion).
+- **test-levels-framework.md** — choosing integration vs e2e coverage (applied: this is a live-infra integration suite, distinct from unit tests).
+- **test-priorities-matrix.md** — P0–P3 coverage targets (applied: GraphMCP contract = P0 since it recently crashed production; lifecycle/skill-check/lore = P1).
+- **ci-burn-in.md** — staged jobs, skip-unless-env gating, flakiness handling (applied: `RUN_FULL_E2E=1` gate, not in CI default).
+
+Frontend-only fragments (`fixture-architecture.md`, `network-first.md`, `selector-resilience.md`, `timing-debugging.md`, Playwright Utils) were **not** loaded — `detected_stack = backend`.
+
+See `resources/tea-index.csv` for the complete fragment mapping.
+
+---
+
+## Test Execution Evidence
+
+Step 5 — scaffold validation (no live infra; gates off):
+
+```
+$ npx vitest run tests/integration
+ RUN  v3.2.6
+ ↓ tests/integration/phase1.test.ts (2 tests | 2 skipped)
+ ↓ tests/integration/graphmcp/contract.test.ts (7 tests | 7 skipped)
+ ↓ tests/integration/graphmcp/lore-and-events.test.ts (2 tests | 2 skipped)
+ ↓ tests/integration/graphmcp/encounter-lifecycle.test.ts (3 tests | 3 skipped)
+ ↓ tests/integration/graphmcp/skill-check.test.ts (2 tests | 2 skipped)
+ ↓ tests/integration/graphmcp/long-encounter.test.ts (1 test | 1 skipped)
+ Test Files  6 skipped (6)
+      Tests  17 skipped (17)
+   Duration ~600ms
+```
+→ exit 0. All scaffolds transpile and skip cleanly (CI-safe; no live infra required to import).
+
+Unit suite (regression guards for the `/encounter generate` crash live here, not in the live suite):
+
+```
+$ npx vitest run tests/unit
+ Test Files  33 passed (33)
+      Tests  404 passed (404)
+   Duration 3.3s
+```
+→ `tests/unit/graphmcpClient.test.ts` (semanticSearch / listEncounters / queryAsNPC wrong-shape normalization), `tests/unit/historyTrim.test.ts` (FIFO trim), `tests/unit/specsToolsConsistency.test.ts` (spec tool refs vs registered plugins) all green.
+
+### Live-pass evidence (real Discord + LiteLLM/Ollama + Redis + GraphMCP)
+
+Provisioned infra: test guild + `DISCORD_TOKEN` (bot under test) + `E2E_DRIVER_TOKEN` + `E2E_TEST_GUILD_ID` + `E2E_TEST_CHANNEL_ID`, with host overrides `GRAPHMCP_URL=http://localhost:9000 REDIS_URL=redis://localhost:6379` (dotenv does not clobber command-line env, so these win over `.env`'s Docker-internal hostnames). Gate: `RUN_FULL_E2E=1`.
+
+**AC1 — GraphMCP contract (7 tests):** all PASS live. Surfaced and fixed 2 latent `src/graphmcp/client.ts` bugs during live validation — `semanticSearch` mapped the wrong field (live returns `text`, code read `content` → would crash `encounter.ts:510` and silently break mention handling), and `queryAsNPC` returned null arrays unnormalized. Fixed with `toSemanticChunk` + array coercion; locked by new unit regression tests.
+
+**AC2 — encounter lifecycle (3 tests):** all PASS live (18.96s). S2.1 start → real thread + persisted `SessionState`; S2.2 driver turn → LLM reply, history grows; S2.3 end → resolved + `log_encounter` read-after-write (`list_encounters` matched by run-id in summary → `get_encounter` returns full `EncounterDetails` with participants).
+
+**AC5 — long encounter (1 test × 4 strategies, run one-per-invocation via `E2E_STRATEGY`):** all PASS live. Each writes a run-tagged spec (market-thief derived, unique `encounterId`/`title`), drives turns via the real scheduler with skill checks resolved through `handleRollInteraction`, and reads the `encounter_resolve` log back from GraphMCP.
+
+| strategy | outcome | driver turns | skill checks | skills exercised | GraphMCP summary |

+→ **3 distinct goal outcomes** (`catch`, `negotiate`, `escape`) confirmed across the strategies; **long_explore delivers the 20–30 turn target (~21 driver turns) with complex skill usage (8 checks across 3 skills)**; every run verifies the final output in GraphMCP via `list_encounters` + `get_encounter` (title records the `outcomeId`, summary/participants/type confirmed). The `bystander` strategy exercised the Persuasion path but the LLM classified the juggler's tackle as `catch` rather than `bystander_chase` (a fuzzy outcome-boundary judgment — `catch` is still a valid spec goal, so the test passes; the test asserts outcome validity, not a specific outcome per strategy).
+
+**Bugs surfaced + fixed during live AC5 validation:**
+- `src/bot/handlers/messageRouter.ts` `runLLMTurn` — a turn could die **silently** (no history growth, no error) when the LLM reply had no parseable narrative/tool, hit the filtered-already-retried path, or threw inside the post-LLM block (the scheduler's `try/finally` has no `catch`). The narrator would go quiet and the generation never completed. Fixed: wrapped post-LLM logic in `try/catch` (logs `[messageRouter] turn processing failed:`), track an `appended` flag, and **always grow history by ≥1** with a `[NO RESPONSE]` fallback beat; hardened the filter guards against non-string `content`. 404 unit tests still pass.
+- `tests/integration/graphmcp/support/cleanup.ts` `flushRedisForGuild` — used pattern `session:*${guildId}*` but session keys are `session:<threadId>` (a Discord snowflake, no guild id), so it matched nothing and stale sessions accumulated across runs. Fixed: scan `session:*`, delete only `e2e-`-prefixed (run-tagged) ones; added `deleteSession(threadId)` for per-run `afterAll` cleanup.
+- `long-encounter.test.ts` polling baseline — measured `history.length` before `addMessage`, so the user message itself satisfied the `> prevLen` poll and the loop spun 30× instantly without waiting for LLM turns. Fixed: baseline measured after the user message / after `handleRollInteraction` returns.
+
+**AC3 + AC4:** scaffolds transpile + skip cleanly; live execution pending a dedicated run window (AC1/AC2/AC5 already exercise the skill-check tool and GraphMCP read-after-write paths end-to-end).
+
+---
+
+## Notes
+
+- This repo has **no BMad config** (`_bmad/` absent) — no `tea/config.yaml`, no `custom/` overrides, no `project-context.md`. The skill ran on all defaults; `user_name`/`communication_language` defaulted (English). Agent-identity/persona bits from BMad are absent.
+- The GraphMCP contract suite (AC1) is the highest-value coverage: it directly guards the `semanticSearch`/`listEncounters` wrong-shape crash recently fixed in `src/graphmcp/client.ts` (the `/encounter generate` `TypeError: Cannot read properties of undefined (reading 'length')`).
+- Real-LLM tests are inherently slow (seconds per turn) and non-deterministic; budget generous per-test timeouts (60–120s) and prefer structural assertions + polling over exact-text asserts.
+- The hybrid slash-command pattern depends on `command.execute(interaction, client)` (`src/bot/index.ts:151`) and real channel objects from the connected client — no Discord API for bot-to-bot slash commands exists.
