chore(openspec): drop 9 superseded proposals + 11 stub archive files

Drop 9 batch proposals that are superseded by the boocode-lift-analysis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.

+## Why
+
+The audit-harness (hooks + skills + AuditContext) and Parlant (GuidelineStore + Journey engine) provide two proven patterns for agent session management. audit-harness solves context-window loss through persistent audit trails, graded recovery, and structured commands (/start → /end → /recover → /report-daily). Parlant solves behavioral consistency through a versioned guideline document store with tag/label-based retrieval, journey-based SOPs, and backtrack detection.
+
+Porting these patterns into boocode's agent ecosystem gives every agent working in this repo persistent session management, cross-session user correction awareness, and behavioral guideline enforcement — without building any of it from scratch.
+
+## What Changes
+
+### New Capabilities
+
+- **Data Directory Convention**: `.boo/runs/` directory with buffer files, session dirs, `.current_session` handshake, unified `index.json`. `AUDIT_DOT_DIR` env var for platform override.
+
+- **Session Lifecycle Commands**: `/start` creates named audit sessions with auto-recovery (L0+L2). `/end` flushes buffers, runs integrity checks, generates `session_summary.md`. `/recover` graded context loading (L0–L3). `/report-daily` aggregates all sessions into a 7-section report; `/report-daily review` also runs morning self-review.
+
+- **User Correction Tracking**: Structured `user_correction` records with `original_claim`/`correction`/`principle_extracted`/`persisted_to`. Auto-detected on `/end`. Correction-as-precedent enforcement when agent actions contradict prior corrections.
+
+- **Behavioral Guidelines Store**: Versioned GuidelineDocumentStore ported from Parlant with condition+action+description content model, tag/label filtering, and content-based `find_guideline()`. Journey → guideline auto-projection (SOP nodes → guidelines with follow-up edges). Journey backtrack detection batch.
+
+### Dependencies
+
+- Existing audit-harness patterns (audit-context.py, hooks, skills) reference implementation.
+- Parlant's GuidelineStore (guidelines.py) and JourneyStore (journeys.py) reference implementation.
+- No new external services. File-based JSONL storage (audit-harness pattern).
