chore(openspec): drop 9 superseded proposals + 11 stub archive files

Drop 9 batch proposals that are superseded by the boocode-lift-analysis
(boocontext-audit, conductor upgrades, self-healing/verify-gate skills):
add-3tier-memory, import-llm-evaluator, import-pregel-engine, plugin-platform,
conductor-evolution, code-intelligence-upgrade, dev-workflow, ui-overhaul,
agent-reliability.

Delete 11 stub archive files (49-66B each, 'Status: Shipped. Archived.' only)
that provide zero documentation value over the existing CHANGELOG.md + git tags.

+# Session Lifecycle Commands — Spec
+
+## Overview
+
+Four agent-invocable commands that manage audit session lifecycle. Each command is a skill markdown file loaded by the agent on invocation.
+
+## /start
+
+```
+/start "task description"
+```
+
+Creates a named audit session:
+
+1. Generate `session_id = adhoc_YYYYMMDD_HHMM`
+2. `mkdir -p .boo/runs/{session_id}`
+3. Write `session.json`:
+   ```json
+   {
+     "session_id": "adhoc_20260320_1400",
+     "task": "task description",
+     "start_time": "2026-03-20T14:00:00Z",
+     "status": "in_progress",
+     "expected_record_types": ["data", "change", "conversation"]
+   }
+   ```
+4. Write `.boo/runs/.current_session` containing session_id (handshake for hooks)
+5. Run context recovery:
+   - L0: read `index.json` → last 5 entries
+   - L2: scan recent audit_trail.jsonl for `user_correction` records
+6. Output recovery summary: recent activity, corrections, priorities
+7. Check for unfinished sessions: scan for `status: "in_progress"` sessions, prompt user
+
+## /end
+
+```
+/end
+```
+
+Ends the current audit session:
+
+1. Read `.current_session` → get session_id
+2. Collect remaining buffer data from `audit_buffer.jsonl` + `audit_pending.jsonl`
+3. Append to `audit_trail.jsonl`
+4. Clear buffer files
+5. Extract `user_correction` records from audit_trail
+6. Run integrity checks:
+   - Has records? (>0 audit_trail lines)
+   - All files covered? (changes in audit_trail match modified files)
+   - Corrections persisted? (persisted_to is non-empty)
+7. Generate `session_summary.md`
+8. Update `session.json` status=completed, end_time
+9. Clear `.current_session`
+
+## /recover
+
+```
+/recover              # L0+L1+L2
+/recover full         # L3 (full audit_trail)
+/recover {session_id} # load specific session
+```
+
+Graded context loading:
+
+- L0 (~200t): index.json → last 5 entries (id, task, status)
+- L1 (~500t): .current_session + session.json + last 3 audit_trail entries
+- L2 (~1000t): scan all audit_trails for user_correction records + conclusions + daily report §4+§6
+- L3 (~3000t): full audit_trail.jsonl + audit_pending.jsonl
+
+## /report-daily
+
+```
+/report-daily              # today
+/report-daily 20260319     # specific date
+/report-daily review       # + morning self-review
+```
+
+7-section report:
+
+1. Task overview (from index.json)
+2. Operation stats (tool counts)
+3. Change records (file modifications)
+4. User feedback & corrections
+5. Anomaly alerts
+6. Backlog tracking
+7. Integrity summary
+
+`review` variant: adds morning self-review with trend analysis and recommended priorities.
