# Session End Skill

> **Platform Note:** State files (STATE.md, wave-scope.json) live in the platform's native directory: `.claude/` (Claude Code), `.codex/` (Codex CLI), or `.cursor/` (Cursor IDE). All references to `.claude/` below should use the platform's state directory. Shared metrics live in `.orchestrator/metrics/`. See `skills/_shared/platform-tools.md`.

> **Project-instruction file:** `CLAUDE.md` and `AGENTS.md` (Codex CLI) are transparent aliases — see [skills/_shared/instruction-file-resolution.md](../_shared/instruction-file-resolution.md). All references to `CLAUDE.md` in this skill resolve via that precedence rule.

## Phase 0: Bootstrap Gate

Read `skills/_shared/bootstrap-gate.md` and execute the gate check. If the gate is CLOSED, invoke `skills/bootstrap/SKILL.md` and wait for completion before proceeding. If the gate is OPEN, continue to Phase 1.

<HARD-GATE>
Do NOT proceed past Phase 0 if GATE_CLOSED. There is no bypass. Refer to `skills/_shared/bootstrap-gate.md` for the full HARD-GATE constraints.
</HARD-GATE>

## Phase 0.5: Parallel-Aware Preamble

> Skip silently when `persistence: false` in Session Config.

Before Phase 1, run the parallel-aware preamble per `skills/_shared/parallel-aware-preamble.md`. The preamble detects other active sessions in the worktree-family via `findPeers(repoRoot, { mySessionId })`, classifies the caller's mode via `classifyMode(callerMode)` against the exclusivity-matrix, and fires the appropriate AUQ on conflict.

**Outcome handling:**
- `PASS_THROUGH` → continue to Phase 1
- `EXCLUSIVE_BLOCKED` → exit Phase 0 cleanly per the AUQ outcome
- `PROMOTION_OFFER` → user picks Worktree-Promotion (see `parallel-aware-auq.md` outcome-handling — calls `enterWorktree()`), in-place + Deviation, or Abbrechen

For session-end specifically: the preamble is DETECTION-ONLY. The lock-release path in later phases keeps its current behavior — releasing the OWN session's lock requires no matrix consultation.

**Implementation reference:** `skills/_shared/parallel-aware-preamble.md § Implementation`.
**AUQ reference:** `skills/_shared/parallel-aware-auq.md`.

## Phase 1: Plan Verification

Read back the session plan that was agreed at the start. For EACH planned item:

### 1.1 Done Items
- **Verify with evidence**: read the changed files, check git diff, run relevant test
- Confirm acceptance criteria are met
- Mark as completed

### 1.2 Partially Done Items
- Document what was completed and what remains
- Create a VCS issue for the remaining work with:
  - Title: `[Carryover] <original task description>`
  - Labels: `priority:<original>`, `status:ready`
  - Description: what's done, what's left, context for next session
- Link to original issue if applicable

### 1.3 Not Started Items
- Document WHY (blocked? de-scoped? out of time?)
- If still relevant: ensure original issue remains `status:ready`
- If no longer relevant: close with comment explaining why

### 1.4 Emergent Work
- Tasks that were NOT in the plan but were done (fixes, discoveries)
- Document and attribute to relevant issues
- If new issues were identified: create them on the VCS platform

### 1.5 Discovery Scan (if enabled)

Read `skills/session-end/discovery-scan.md` for embedded discovery dispatch and findings triage.

### 1.6 Safety Review

> Skip if `persistence` is `false` in Session Config (STATE.md won't exist).

Review safety metrics from the session. This is informational — it does NOT block the session close.

1. Read `<state-dir>/STATE.md` to extract:
   - **Circuit breaker activations**: agents that hit maxTurns (`PARTIAL`), agents that spiraled (`SPIRAL`), agents that failed (`FAILED`)
   - **Worktree status**: which agents used worktree isolation, any fallbacks or merge conflicts
2. Read enforcement hook logs from stderr (if captured): count of scope violations blocked/warned, command violations blocked/warned
3. Summarize:
   ```
   Safety review:
   - Agents: [X] complete, [Y] partial (hit turn limit), [Z] spiral/failed
   - Enforcement: [N] scope violations, [M] command blocks
   - Isolation: [K] agents in worktrees, [J] fallbacks
   ```
4. If any agents were `SPIRAL` or `FAILED`, ensure carryover issues exist (cross-reference with Phase 1.2)

5. **Carryover validation fallback (#261):** Walk each Wave History entry in STATE.md. For every agent whose status is `SPIRAL` or `FAILED`, check whether the line ends with a `→ issue #NNN` suffix (or `→ existing #NNN`). If the suffix is absent, the auto-create call in wave-executor did not run (e.g. a consumer-project #251 V0.x.y-close incident where the session crashed before dispatch completed, or the CLI was offline at detection time). Retroactively file the carryover via `createSpiralCarryoverIssue`:

   ```js
   import { createSpiralCarryoverIssue } from '${PLUGIN_ROOT}/scripts/lib/spiral-carryover.mjs';

   // For each SPIRAL/FAILED agent missing the "→ issue #NNN" suffix:
   const result = await createSpiralCarryoverIssue({
     taskDescription: '<agent task from Wave History>',
     kind: 'SPIRAL', // or 'FAILED'
     context: '<Deviations / error context from STATE.md>',
     priority: 'high',
     vcs: '<from Session Config>'
   });
   // result.created → note new issue id in Final Report under "New Issues Created"
   // result.skipped === 'duplicate' → an earlier session already filed one; record the existing id
   // result.skipped === 'error' → log in Final Report as "⚠ carryover filing failed for <task>: <error>" and continue (do NOT block close)
   ```

   The module is idempotent via its task-hash dedup marker, so re-running the fallback across sessions will not create duplicates.

### 1.7 Metrics Collection

Read `skills/session-end/metrics-collection.md` for JSONL schema and conditional field rules.

### 1.8 Session Review

Dispatch the session-reviewer agent to verify implementation quality before the quality gate:

> On Codex CLI, dispatch via the `session-reviewer` agent role defined in `.codex-plugin/agents/session-reviewer.toml`.

1. Invoke `subagent_type: "session-orchestrator:session-reviewer"` with:
   - **Scope**: all files changed this session (from `git diff --name-only` against the base branch)
   - **Context**: the session plan (issues, acceptance criteria) and all wave results from STATE.md
2. Wait for the reviewer's **Verdict**:
   - **PROCEED** — continue to Phase 2
   - **FIX REQUIRED** — disposition each listed item by severity:

     | Finding class | Disposition |
     |---|---|
     | HIGH+ / blocking review finding | Fix inline if quick (<2 min); else create an issue (`priority:high`, `status:ready`) and note it in the Final Report |
     | MED / LOW review finding | Fold in-session if quick; else record under "Unresolved Review Findings" in the Final Report — DO NOT create an issue (#617) |
     | Planned-carryover (item was in the plan, not finished) | ALWAYS create a `[Carryover]` issue per Phase 1.2 — unchanged |
     | SPIRAL / FAILED agent carryover | ALWAYS file via `createSpiralCarryoverIssue` per Phase 1.6 — unchanged |

### 1.9 Mission-Status Classification (when `mission-status` present in STATE.md)

> Skip if `persistence` is `false` in Session Config, or if `mission-status:` is absent from STATE.md frontmatter. When absent, fall back to binary checkbox detection in 1.1–1.4 unchanged — full backward compat.

When STATE.md frontmatter contains a `mission-status:` array (set by session-plan + wave-executor per #340), use the enum values to classify items into the 1.1–1.4 buckets. Read the array via `parseMissionStatus(frontmatter)` from `scripts/lib/state-md.mjs`.

**Classification mapping:**
- `status: completed` → **1.1 Done Items** (item finished; verify with evidence per 1.1)
- `status: testing` or `status: in-dev` → **1.2 Partially Done** (carryover; document what remains)
- `status: validated` or `status: brainstormed` → **1.3 Not Started** (carryover; check if still relevant)
- Items NOT present in the `mission-status:` array → fall back to binary checkbox detection per 1.1–1.4 unchanged

**Backward compat:** When `mission-status:` is absent from STATE.md (pre-#340 STATE.md files, or sessions where session-plan did not emit the block), behave exactly as before — enum classification is skipped entirely and 1.1–1.4 binary checkbox logic runs as the sole classification mechanism.

### 1.10 Mission Status Breakdown (when `mission-status` present)

> Skip if `mission-status:` is absent from STATE.md frontmatter (backward compat — no breakdown emitted).

After classifying items in Phase 1.9, produce a **Mission Status breakdown** subsection as part of the closed/carryover summary output. Count the number of tasks at each enum value across ALL waves:

```
### Mission Status Breakdown
- completed:    <N> tasks
- testing:      <N> tasks
- in-dev:       <N> tasks
- validated:    <N> tasks
- brainstormed: <N> tasks
- Total:        <N> tasks across <W> waves
```

Rules:
- Count each task-id entry from the `mission-status:` frontmatter array by its current `status` value.
- `completed` maps to Phase 1.1 (Done). `testing` + `in-dev` map to Phase 1.2 (Partial). `validated` + `brainstormed` map to Phase 1.3 (Not Started).
- Include this block in the Phase 6 Final Report under `### Carried Over` or as a standalone subsection immediately after the Completed/Carried Over/New Issues lists.
- When all tasks are `completed`, the breakdown still appears (confirms clean session state).

## Phase 2: Quality Gate

> **Verification Reference:** See `verification-checklist.md` in this skill directory for the full quality gate checklist.

Run ALL checks listed in the verification checklist. If any check fails: fix if quick (<2 min), otherwise create a `priority:high` issue. Do NOT commit broken code.

### Phase 2.0a: Echo-Stub Detection (GH #42)

`gate-full.mjs` emits a top-level `stubbed: {}` map in its JSON result, keyed by check name (`typecheck`, `test`, `lint`); value is `{ kind: 'echo'|'noop' }`. When any check was short-circuited as a stub, `runCheck()` already returned `status: 'pass'` — so the overall gate verdict is green, but the result is meaningless.

**Detection:** immediately after parsing the `gate-full` JSON result, evaluate:

```js
const stubbedEntries = Object.entries(result.stubbed ?? {});
```

**If `stubbedEntries.length > 0`**, surface a HIGH WARN block in the close summary:

```
⚠ QUALITY GATE STUBBED — <N> command(s) are echo/noop stubs, not real checks:
  - <check-name>: <kind> stub  (configured: "<command string>")
Re-configure with a real test command in CLAUDE.md Session Config before /close,
OR document this exception in /close --reason.
```

**Behavior by `enforcement` mode:**

- `enforcement: strict` — **block /close**. Treat as a Phase 2 failure. Present the WARN block and exit without committing.
- `enforcement: warn` (default) — continue, but write `quality-gate-stubbed: true` to STATE.md Deviations so the metrics writer captures it.
- `enforcement: off` — silent. Emit a single-line `stderr` log only (`echo-stub detected: <check-name>`).

**Recipe:** for container-based test runners (e.g. EspoCRM PHPUnit) where an echo-stub was the historical workaround, see [`docs/recipes/quality-gate-container-pattern.md`](../../docs/recipes/quality-gate-container-pattern.md).

**Source issue:** GH #42 (root cause: a consumer-project #251 V0.15.7-close incident — silent false-positive close-verdicts from echo-stub test commands).

### 2.1 Vault Validation (if configured)

Read `skills/session-end/vault-operations.md` for validator bash contract and reporting matrix.

### 2.2 CLAUDE.md (or AGENTS.md) Drift Check (if configured)

Read `skills/session-end/drift-operations.md` for checker bash contract and reporting matrix. Complements 2.1: vault-sync validates frontmatter inside the vault tree; drift-check validates narrative claims (paths, counts, issue refs, session-file refs) in top-level repo docs.

### 2.3 Vault Staleness Check (if configured)

> Skip this subsection if `vault-staleness.enabled` is not `true` (default: `false`).

#### Step 1 — Resolve mode

Read `vault-staleness.mode` from `$CONFIG` (default: `warn`). Valid values: `off | warn | strict`.

If `mode === 'off'`, skip Phase 2.3 entirely.

#### Step 2 — Invoke staleness probes

Both probes already ship in `skills/discovery/probes/`. Invoke each via Node import (no shell-out):

```js
import { runProbe as runStaleness } from '$REPO_ROOT/skills/discovery/probes/vault-staleness.mjs';
import { runProbe as runNarrative }  from '$REPO_ROOT/skills/discovery/probes/vault-narrative-staleness.mjs';

const projectStaleness = await runStaleness(projectRoot, config);
const narrativeStaleness = await runNarrative(projectRoot, config);
```

Each probe returns `{ findings: Array, metrics: Object, duration_ms: Number }` and auto-appends a JSONL summary record to its respective metrics file.

#### Step 3 — Aggregate and route by mode

```
totalFindings = projectStaleness.findings.length + narrativeStaleness.findings.length
```

- `mode === 'warn'` (default): report findings to closing report Docs Health line. Never block close.
- `mode === 'strict'`:
  - If `totalFindings === 0`: continue, log `Vault staleness: clean (mode=strict)`.
  - If `totalFindings > 0`: BLOCK the close. Present the findings list and offer override:
    - On Claude Code: AskUserQuestion with options:
      1. "Fix and retry Phase 2.3" (Recommended) — exit close, let user investigate
      2. "Override and close" — proceed, log a Deviation entry in STATE.md `## Deviations`:
         `- [<ISO timestamp>] Phase 2.3: Vault staleness strict-mode findings overridden by user. Findings: <count> (projects: <N>, narratives: <M>).`
      3. "Abort close" — exit close without writing
    - On Codex CLI / Cursor IDE: same options as numbered Markdown list.

#### Step 4 — Surface to closing report

Pass the aggregated counts and mode forward to Phase 6 Final Report (Docs Health line — see Phase 6 below).

## Phase 3: Documentation Updates

> **Final heartbeat (#590-3)** — at Phase 3 entry, refresh the session-lock heartbeat BEFORE the multi-minute close-out chain (vault-mirror, dialectic, durable-commit, metrics). A long-idle deep session may not have had PostToolBatch activity for >4h; without a refresh the 4h-TTL lock would lapse mid-close and appear stale to a concurrent session. Place this call BEFORE Phase 3.8 Session Lock Release (which deletes the lock — refreshing a deleted lock is a no-op). Best-effort: a failure must NOT block the close.
>
> ```js
> // Final heartbeat (#590-3) — refresh before the multi-minute close-out (vault-mirror, dialectic, durable-commit)
> // so a long-idle deep session's 4h-TTL lock does not lapse mid-close.
> // BEFORE Phase 3.8 lock-release (which deletes the lock).
> import { updateHeartbeat } from 'scripts/lib/session-lock.mjs';
> updateHeartbeat({ sessionId, repoRoot: process.cwd() });
> ```
>
> Skip silently if `persistence: false` in Session Config (no session.lock exists in that mode).

### 3.0 Defensive Cleanup

Delete `<state-dir>/wave-scope.json` if it still exists:

```bash
rm -f <state-dir>/wave-scope.json
```

This should have been cleaned up by wave-executor after the final wave, but crashed sessions or interrupted executions may leave it behind. A stale scope manifest from a previous session could incorrectly restrict the next session's enforcement hooks.

### 3.1 SSOT Files
- Update `STATUS.md` / `STATE.md` if they exist (metrics, dates, status)
- Update `CLAUDE.md` (or `AGENTS.md` on Codex CLI) if patterns or conventions changed during this session
- Check `<state-dir>/rules/` — if a new pattern was established, suggest a new rule file

### 3.2 Docs Verification (docs-orchestrator integration)

> Skip this subsection if `docs-orchestrator.enabled` config is not `true` (default: `false`). Also skip entirely if `docs-orchestrator.mode` is `off`.

Reads `docs-tasks` from STATE.md frontmatter (written by wave-executor Pre-Wave 1b), computes `CHANGED_FILES` via `git diff --name-only "$SESSION_START_REF..HEAD"`, and runs a per-task verification loop (outcome: `ok`/`partial`/`gap`). In `warn` mode logs results non-blocking; in `strict` mode blocks on any gap and presents an AskUserQuestion override prompt. Emits a `### Documentation Coverage (docs-orchestrator)` block for inclusion in the Phase 6 Final Report.

**See `phase-3-2-docs-verification.md` for full details.**

### 3.2a Session Handover (for significant sessions)
If this session made substantial changes, create or update:
- `<state-dir>/session-handover/` doc with: tasks completed, resume point, metrics changed, issues opened/closed
- Or update `<state-dir>/STATE.md` with session digest

### 3.3 Claude Rules Freshness
Review `<state-dir>/rules/` files that are relevant to this session's work:
- Are the rules still accurate after this session's changes?
- Should any rule be updated with new patterns?
- Should a new path-scoped rule be created?
- Suggest changes but DO NOT modify without user confirmation

### 3.4 Update STATE.md

> **Ownership Reference:** See `skills/_shared/state-ownership.md`. session-end is authorized to set `status: completed` plus the optional `updated` timestamp (#184), and — as of Phase A of Epic #271 — the 5 Recommendation fields written by Phase 3.7a. No other fields.

> **Runtime Ordering Note (Epic #271 Phase A):** Phase 3.4's `status: completed` write executes LAST in Phase 3, AFTER Phase 3.7 (sessions.jsonl) and Phase 3.7a (Compute and Write Recommendations). The ordinal position here (3.4) is kept for historical compatibility; the canonical runtime order is `3.1 → 3.2 → 3.3 → 3.4a → 3.5 → 3.5a → 3.6 → 3.6.5 → 3.6.7 → 3.7 → 3.7a → 3.7b → 3.4`. Rationale: Phase 3.7a reads in-memory session metrics and writes the 5 Recommendation fields via `updateFrontmatterFields`; that write must complete BEFORE the STATE.md frontmatter is finalized with `status: completed` so the Recommendation fields are visible to the next session-start while STATE.md is still `status: active`. Crash-resilience: if `/close` aborts between 3.7a and 3.4, STATE.md carries `status: active` + Recommendations; session-start Phase 1.5 offers resume (and the banner renders). If the reverse ordering were used (status: completed first), a crash would leave `status: completed` without Recommendations — the Reader would silently no-op the banner, losing the handoff.

> Gate: Only run if `persistence` is enabled in Session Config and `<state-dir>/STATE.md` exists.
1. Set frontmatter `status: completed`
2. Record final wave count and completion time in the frontmatter
3. Touch `updated: <ISO 8601 UTC>` in the frontmatter (issue #184). Use `scripts/lib/state-md.mjs` → `touchUpdatedField` for safety:
   ```bash
   node --input-type=module -e "
   import {readFileSync, writeFileSync} from 'node:fs';
   import {touchUpdatedField} from '${PLUGIN_ROOT}/scripts/lib/state-md.mjs';
   const p = '<state-dir>/STATE.md';
   writeFileSync(p, touchUpdatedField(readFileSync(p, 'utf8'), new Date().toISOString()));
   "
   ```
   Silent no-op if the file has no frontmatter.
4. Keep the file as a record — do NOT delete it (next session-start reads it)

If STATE.md doesn't exist, skip this subsection.

### 3.4a Coordinator Snapshot Cleanup (#196)

Pre-dispatch snapshots (`refs/so-snapshots/<sessionId>/wave-*`) are created by wave-executor before each wave dispatch so that session-start can offer recovery if a session is interrupted mid-wave. On a clean close those snapshots are no longer needed and should be deleted. In addition, orphaned refs from older sessions that were never cleaned up (e.g. after a hard crash) are garbage-collected using an age-based policy (14 days).

> Gate: Only run if `persistence` is `true` in Session Config. Skip entirely when persistence is off (snapshots are never written in that mode).

```bash
node --input-type=module -e "
import { listSnapshots, deleteSnapshot, gcSnapshots } from '${PLUGIN_ROOT}/scripts/lib/coordinator-snapshot.mjs';

// Step A: delete this session's snapshots (clean close → we don't need them)
const mine = await listSnapshots({ sessionId: '${SESSION_ID}' });
for (const s of mine) {
  const r = await deleteSnapshot({ refName: s.ref });
  if (!r.ok) console.error('snapshot cleanup:', r.error);
}

// Step B: GC orphans older than 14 days (non-fatal)
const gc = await gcSnapshots({ olderThanDays: 14 });
console.log(\`snapshot cleanup: deleted \${mine.length} from this session + \${gc.deletedCount} expired orphans (scanned \${gc.scanned}).\`);
"
```

Failures in either step are logged to stderr but do **not** block session close — a missed cleanup is self-healing via the 14-day GC on the next session.

This cleanup is the counterpart to the session-start Phase 1.5 recovery prompt: once a session closes cleanly, future sessions must not be offered recovery for its snapshots.

### 3.5 Session Memory

> Gate: Only run if `persistence` is enabled in Session Config AND platform is Claude Code (session memory at `~/.claude/projects/` is Claude Code-only). Learnings (Phase 3.5a) and metrics (Phase 3.7) still write to `.orchestrator/metrics/` on all platforms.

1. Create `~/.claude/projects/<project>/memory/session-<YYYY-MM-DD>.md` with:
   - Frontmatter: `name`, `description` (1-line summary), `type: project`
   - `## Outcomes` — per-issue status (completed / partial / not started) with evidence
   - `## Learnings` — patterns discovered, architectural insights, gotchas
   - `## Next Session` — priority recommendations, suggested session type, blockers
2. Update `~/.claude/projects/<project>/memory/MEMORY.md`:
   - Under a `## Sessions` heading (create if missing), add:
     `- [Session <date>](session-<date>.md) — <one-line summary>`

### 3.5a Learning Extraction + 3.6 Memory Cleanup & Learnings Write

Read `skills/session-end/learning-patterns.md` for extraction heuristics, confidence updates, passive decay, and JSONL write procedure.

### 3.6.3 Memory Proposals Collection (#501, F2.1)

> Gate: Skip this phase entirely when ANY of:
> - `persistence` is `false` in Session Config
> - `memory.proposals.enabled` is `false` (default: `true`)
> - `.orchestrator/metrics/proposals.jsonl` does not exist OR contains zero entries

After learnings are written (Phase 3.6) and BEFORE auto-dream dispatch (Phase 3.6.5), collect agent-proposed memory entries written during this session and present them to the operator via `AskUserQuestion` multiSelect. Approved entries flow to `learnings.jsonl` with `_provenance: agent-proposed@<wave-id>`. Rejected entries are archived to `.orchestrator/proposals.rejected.log`.

The proposals queue is populated mid-session by wave-executor agents calling `node scripts/memory-propose.mjs --type ... --subject ... --insight ... --evidence ... --confidence ...`. The CLI enforces:
- Quota per wave (default 5, configurable via `memory.proposals.quota-per-wave`)
- Confidence floor (default 0.5, configurable via `memory.proposals.confidence-floor`)
- Wrong-context guard (CLI exits non-zero when STATE.md `status` is not `active`)

#### Coordinator-direct procedure

1. Read Session Config: `memory.proposals.enabled` (default `true`), `memory.proposals.quota-per-wave` (default 5), `memory.proposals.confidence-floor` (default 0.5), `auto-dream.min-confidence` (default 0.5 — issue #566; SECOND gate above the write-time `memory.proposals.confidence-floor`).

2. Invoke `collectProposals` from `scripts/lib/memory-proposals/collector.mjs`, passing the collect-emit confidence floor from Session Config:
   ```javascript
   import { collectProposals } from '${PLUGIN_ROOT}/scripts/lib/memory-proposals/collector.mjs';
   const { queue, stats, perWaveSummaries } = await collectProposals({
     repoRoot: process.cwd(),
     // Issue #566: collect-emit confidence floor. Records with
     // `record.confidence < minConfidence` are dropped from `queue` (but
     // counted in stats). When the key is absent, defaults to 0.5 via the
     // `_parseAutoDream` parser.
     minConfidence: config['auto-dream']?.['min-confidence'],
   });
   ```

3. If `queue.length === 0`: log `memory-proposals: queue empty (stats: ${JSON.stringify(stats)})` and continue.

4. **AUQ pagination logic**: partition the queue into FIFO batches of 4 inline:

   - Empty queue → silent skip (no AUQ rendered).
   - 1-4 items → single multiSelect call with all items as options.
   - 5+ items → sequential multiSelect calls in batches of 4 (FIFO order; final batch may have < 4 items).

   ```javascript
   // Inlined from former scripts/lib/memory-proposals/auq-partition.mjs (PRD F2.2 #502 closed; see #558 M2).
   const BATCH_SIZE = 4;
   const batches = [];
   if (Array.isArray(queue) && queue.length > 0) {
     for (let i = 0; i < queue.length; i += BATCH_SIZE) {
       batches.push(queue.slice(i, i + BATCH_SIZE));
     }
   }
   ```

   Then iterate `batches` and emit one `AskUserQuestion` per batch with `header: "Memory — Confirm Proposals (Batch N of M)"`. Option label format: `[<type-12>] | <subject-40> | conf=X.XX`. Option description: `evidence: <first 60 chars of insight>`. `multiSelect: true`.

5. After all batches answered, partition the queue into `approved` (any option selected across all batches) and `rejected` (all unselected).

6. Invoke `writeApproved` and `archiveRejected` from `scripts/lib/memory-proposals/sink.mjs`:
   ```javascript
   import { writeApproved, archiveRejected, clearProposalsJsonl } from '${PLUGIN_ROOT}/scripts/lib/memory-proposals/sink.mjs';
   const writeResult = await writeApproved({ approved, repoRoot, sessionId });
   const archiveResult = await archiveRejected({ rejected, repoRoot, reason: 'user-declined' });
   await clearProposalsJsonl({ repoRoot });
   ```

7. Log outcome for Phase 6 Final Report: `memory.proposals: <queued> queued → <approved> approved, <rejected> rejected (dropped: <dropped> quota, <below_floor> below-floor)`.

#### Failure modes

- If `collectProposals` fails (fs error): log warning `⚠ memory-proposals: collect failed (${err}) — skipping`, do not block session close.
- If `writeApproved` reports errors per-record: log each, but continue (per-record fault isolation per sink contract).
- If `clearProposalsJsonl` fails: log warning; do not block. The file may be re-collected at the next session-end, idempotent.

### 3.6.5 Auto-Dream Dispatch (#502, F2.2)

> Skip this phase if `memory-cleanup-threshold: 0` (kill-switch per PRD F2.2). Also skip on non-Claude-Code platforms (memory dir at `~/.claude/projects/` is Claude Code-only, mirrors Phase 3.5 gate).

After learnings are written (Phase 3.6), determine whether to emit a **manual-cadence nudge** to run `/memory-cleanup --dry-run` in the next session. The decision uses MEMORY.md line count and a sessions-since-last-cleanup signal. There is no `memory-cleanup` agent in the registry, so the historical auto-dream subagent dispatch never fired (see #614) — the nudge replaces it. A manually-run `/memory-cleanup --dry-run` writes a unified-diff proposal to `.orchestrator/pending-dream.md` for the session after that to apply via `/memory-cleanup --apply-pending`.

1. Read `memory-cleanup-threshold` (default 5) and `memory-cleanup-soft-limit` (default 180) from `$CONFIG`.
2. Invoke `shouldDispatchAutoDream` from `scripts/lib/auto-dream.mjs`:

   ```javascript
   import { shouldDispatchAutoDream } from '${PLUGIN_ROOT}/scripts/lib/auto-dream.mjs';
   import { resolveMemoryDir } from '${PLUGIN_ROOT}/scripts/lib/memory-paths.mjs';
   const memoryDir = resolveMemoryDir();
   const decision = await shouldDispatchAutoDream({
     repoRoot: process.cwd(),
     memoryDir,
     threshold: config['memory-cleanup-threshold'] ?? 5,
     softLimit: config['memory-cleanup-soft-limit'] ?? 180,
   });
   ```
3. If `decision.trigger === false`: log `auto-dream: not triggered (${decision.reason})` and continue. Emit no nudge.
4. If `decision.trigger === true`: **do not dispatch a subagent** — there is no `memory-cleanup` agent in `agents/`, so the historical `Agent({…})` dispatch pointed at the agent name `memory-cleanup` (a subagent type that was never built) and never fired (see #614). Instead, emit a manual-cadence nudge and continue:

   `auto-dream: cadence reached (${decision.reason}) — run /memory-cleanup --dry-run manually in the next session, then apply the proposal with /memory-cleanup --apply-pending.`

   The `shouldDispatchAutoDream` decision helper and `scripts/lib/auto-dream.mjs` lib stay in use: they compute the signal that drives this nudge and back the manual `/memory-cleanup` path (`writePendingDream` / `readPendingDream` / `applyPendingDream`).
5. Record the outcome (skipped / nudge-emitted) so Phase 6 Final Report can surface a line: `auto-dream: manual /memory-cleanup --dry-run recommended (cadence reached) — apply with /memory-cleanup --apply-pending next session`.

The pending-dream sidecar at `.orchestrator/pending-dream.md` is intentionally outside the vault tree — vault-mirror (Phase 3.7) must exclude it from its scope so the proposal survives the session close without being mirrored into 50-sessions/.

### 3.6.7 Auto-Dialectic Dispatch (#506, F2.5)

> Skip this phase if `dialectic.cadence: 0` (kill-switch per PRD F2.5 AC3). Also skip if `persistence` is `false` in Session Config.

After learnings are written (Phase 3.6) and the auto-dream decision is made (Phase 3.6.5), determine whether to emit a **manual-cadence nudge** to run `/evolve --dialectic` in the next session. The decision uses sessions-since-last-dialectic counted against `.orchestrator/dialectic-last-run`. There is no `evolve` agent in the registry, and the nearest one (`dialectic-deriver`) is `sandbox-tier: read-only` and cannot write the sidecar — so the historical auto-dialectic subagent dispatch never fired (see #614). On trigger, emit the nudge and advance `.orchestrator/dialectic-last-run`; the timestamp is updated only when the nudge is emitted (not on skip), so the reminder surfaces once per cadence window rather than every session. A manually-run `/evolve --dialectic --dry-run` writes the proposed diff to `.orchestrator/dialectic-pending.md`.

1. Read `dialectic.cadence` (default 5), `dialectic.model` (default haiku), `dialectic.budget-tokens` (default 8000) from `$CONFIG`.

2. Invoke `shouldDispatchAutoDialectic` from `scripts/lib/auto-dialectic.mjs`:
   ```javascript
   import { shouldDispatchAutoDialectic } from '${PLUGIN_ROOT}/scripts/lib/auto-dialectic.mjs';
   const decision = await shouldDispatchAutoDialectic({
     repoRoot: process.cwd(),
     cadence: config.dialectic?.cadence ?? 5,
   });
   ```

3. If `decision.trigger === false`: log `auto-dialectic: not triggered (${decision.reason})` and continue. Emit no nudge. Do NOT update `.orchestrator/dialectic-last-run`.

4. **AC4 precondition guard:** Even if cadence met, if `signals.sessionsSinceLast === 0 && signals.learningsSinceLast === 0`, skip with reason `no-new-input-since-last-run`. The Final Report (Phase 6) MUST include the literal string `dialectic: skipped (no new input since last run)`.

5. If `decision.trigger === true`: **do not dispatch a subagent** (see #614 — no `evolve` agent exists; `dialectic-deriver` is read-only and cannot write the sidecar). Instead, emit a manual-cadence nudge and continue:

   `auto-dialectic: cadence reached (${decision.reason}) — run /evolve --dialectic --dry-run manually in the next session, review .orchestrator/dialectic-pending.md, then apply with /evolve --dialectic --apply.`

   The `shouldDispatchAutoDialectic` decision helper and `scripts/lib/auto-dialectic.mjs` lib stay in use: they compute the cadence signal that drives this nudge.

6. When the nudge is emitted (cadence reached), update `.orchestrator/dialectic-last-run` via `writeDialecticLastRun({ repoRoot, isoTimestamp: new Date().toISOString() })` so the cadence counter advances and the nudge does not repeat every session. Atomic; failures non-fatal.

7. Record outcome (skipped / nudge-emitted) for Phase 6 Final Report: `auto-dialectic: manual /evolve --dialectic --dry-run recommended (cadence reached) — apply with /evolve --dialectic --apply next session`.

The `.orchestrator/dialectic-pending.md` sidecar is intentionally outside the vault tree — vault-mirror (Phase 3.7) MUST exclude it from its scope.

> **Dialectic chain rationale** — design choices in the manual `/evolve --dialectic` chain (`/evolve → runDialecticDeriver → dispatchAgent → Agent`). Session-end no longer auto-dispatches this chain (see #614 — the `evolve` agent never existed); the rationale below applies when you run `/evolve --dialectic` manually:
> - **/evolve → subagent (not direct invoke):** the manual `/evolve --dialectic` skill spawns a subagent so the dialectic pass runs in a fresh context window — keeping the deriver's input-heavy payload (top-50 learnings + last-10 sessions + 2 peer cards + steering) out of the invoking coordinator's context, and letting the deriver run as Haiku while the coordinator stays Opus.
> - **/evolve → runDialecticDeriver (not direct dispatchAgent):** /evolve owns argument parsing, config resolution, dry-run/apply gating, error-handling, and sidecar writes; runDialecticDeriver owns the pure derivation pipeline (load → payload → budget-check → dispatch → parse → guard). Separating skill-level orchestration from deriver business logic lets unit tests exercise the deriver without standing up the full evolve skill.
> - **runDialecticDeriver → dispatchAgent (DI boundary):** per `.claude/rules/prompt-caching.md:3`, session-orchestrator forbids direct `@anthropic-ai/sdk` imports in business logic (the harness manages caching at the platform layer). dispatchAgent is the injected boundary — the evolve skill wires the real `Agent({...})` harness call at runtime, tests pass a `vi.fn()` mock. Same DI shape as `scripts/lib/autopilot.mjs::runLoop({opts})` (cf. `scripts/dialectic-deriver.mjs:7-16,531`).

### 3.7 Write Session Metrics

Read `skills/session-end/session-metrics-write.md` for JSONL append, vault-mirror invocation, and behavior matrix.

### 3.7a Compute and Write Recommendations (Epic #271 Phase A)

> Gate: Only run if `persistence` is `true` in Session Config AND `<state-dir>/STATE.md` exists. Skip silently otherwise.

> **Ownership Reference:** See `skills/_shared/state-ownership.md`. session-end is the ONLY writer of the 5 Recommendation fields (`recommended-mode`, `top-priorities`, `carryover-ratio`, `completion-rate`, `rationale`). No other skill may write these keys.

> **Ordering:** Runs AFTER Phase 3.7 (sessions.jsonl is just-written — reads in-memory session metrics, NOT JSONL) and BEFORE Phase 3.4 `status: completed` setting. See the Phase 3.4 Runtime Ordering Note for rationale.

Calls `computeV0Recommendation({completionRate, carryoverRatio, carryoverIssues})` from in-memory session metrics and writes 5 fields to STATE.md frontmatter via `updateFrontmatterFields`. Inputs MUST come from in-memory metrics, NOT re-read from `sessions.jsonl`. On any exception writes `recommendation-compute-failed` to `sweep.log` and does NOT block Phase 3.4.

**See `phase-3-7a-recommendations.md` for full details.**

### 3.7b Durable-Commit Session Telemetry (#490 AC2)

> Gate: Always runs when persistence is enabled. Local execution is a no-op (`enabled: false`).

> **Ordering:** Runs AFTER Phase 3.7a (Recommendations written to STATE.md) and BEFORE Phase 3.4 (`status: completed`). See the Phase 3.4 Runtime Ordering Note canonical order.

Wraps the already-completed Phase 3.7 + 3.7a writes with `withDurableCommit` (from `scripts/lib/autopilot/durable-telemetry.mjs`) for the two session-end-owned files: `.orchestrator/metrics/sessions.jsonl` and `<state-dir>/STATE.md`. `enabled: false` keeps local closes a no-op (`{ok: true, skipped: true}`); the flag flips `true` only in cloud Routines execution so telemetry survives ephemeral-clone reclamation. `autopilot.jsonl` is NOT in scope here — `scripts/lib/autopilot/loop.mjs` owns its commit (#490 Wave-2).

**See `phase-3-7a-recommendations.md` § Phase 3.7b for the full `withDurableCommit` invocation.**

## Phase 3.8: Session Lock Release (#330)

> Gate: Only run if `persistence` is `true` in Session Config. Skip silently otherwise.

After STATE.md is finalized with `status: completed` (Phase 3.4) and Recommendations are written (Phase 3.7a), release the distributed session-lock so the next session can acquire it cleanly:

```javascript
import { release } from 'scripts/lib/session-lock.mjs';
// sessionId = the session identifier established by session-start Phase 1.2 acquire()
//   and stored in .orchestrator/session.lock (session_id field); matches the
//   STATE.md frontmatter `session:` field written during Pre-Wave 1b initialization.
const result = release({ sessionId, repoRoot: process.cwd() });
// result.ok is always true unless a filesystem error occurred.
// result.deleted === true  → lock file removed successfully.
// result.deleted === false → lock was absent or belonged to a different session_id (silent-OK).
```

If `result.deleted === false`, log `info: session-lock not released — already absent or session_id mismatch (no action needed)` and continue. This is a non-error state.

If `result.ok === false` (rare filesystem error), log `⚠ session-lock: release failed — <result.reason>` and continue. Do NOT block the close for a lock-release failure — the TTL provides automatic expiry for the next session.

The lock is released here — AFTER all STATE.md writes are complete and BEFORE the commit is staged in Phase 4.1. This ordering ensures a clean handover: the lock file is absent from the working tree when the commit is assembled, so it is not accidentally staged.

## Phase 4: Commit & Push

### 4.1 Stage Changes
- **Stage files individually**: `git add <file>` — NEVER `git add .` or `git add -A`
- **Always stage these session artifacts** (if modified):
  - `.orchestrator/metrics/sessions.jsonl` (session summary from Phase 3.7)
  - `.orchestrator/metrics/learnings.jsonl` (learnings from Phase 3.6)
  - `<state-dir>/STATE.md` (session state, if persistence enabled)
  - Any files created or modified by wave agents
- Review staged changes: `git diff --cached` — verify every change is from THIS session
- If you see changes you did NOT make, ask the user (parallel session awareness)

### 4.2 Commit
Use Conventional Commits format:
```
type(scope): description

- [bullet points of what changed]
- Closes #IID1, #IID2 (if applicable)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
```

For sessions with many changes, prefer ONE commit per logical unit (not one mega-commit).

### 4.3 Push
```bash
git push origin HEAD
```

### 4.4 GitHub Mirror (if configured in Session Config)
```bash
# Only attempt if 'mirror: github' is in Session Config AND remote exists
git remote get-url github 2>/dev/null && git push github HEAD 2>/dev/null || echo "GitHub mirror: not configured"
```

## Phase 4a: Auto-Promoted Worktree Cleanup (#575 P3.2)

> Skip if `persistence: false` in Session Config. Skip silently if the current worktree is NOT an Auto-promoted sibling (the common case).
