CRITICAL — Q-learning was broken:
- All hardcoded q_init 0.5 → DEFAULT_Q_CONFIG["q_init"] (0.0)
- Fallback values in search, hybrid, cli, mcp → 0.0
- New memories now correctly start at zero and earn value

SECURITY:

- Resolver loading: allowlist openexp.resolvers.* prefix
- Enrichment prompt: XML delimiters + injection guard
- Error responses: generic messages, details only in logs
- lifecycle.py: pass QDRANT_API_KEY to client

CLEANUP:
- Unused imports: math, tempfile, Set, ScrollRequest
- fastembed added to requirements.txt
- pydantic removed (transitive dep only)

73/73 tests pass

Experiences allow the same memory to have different Q-values under
different domains (sales, coding, devops). This enables domain-specific
learning without losing cross-domain knowledge.

Key changes:
- Experience dataclass + YAML loading (search: user dir → bundled → default)
- QCache nested format: {mem_id: {experience: {q_data}}} with auto-migration
- compute_layer_rewards() shared helper (DRY: was duplicated in 3 files)
- 4 new MCP introspection tools (experience_info/top_memories/insights/calibrate)
- CLI --experience flag + experience list|show|stats subcommand
- Hooks propagate OPENEXP_EXPERIENCE env var
- Backward compatible: no env var = identical to current behavior
- 160/160 tests pass (23 new experience tests)

Add memory compaction that clusters similar memories and merges them
into compressed entries with Q-value weighted centroids.

Core algorithm:
- Greedy centroid clustering by cosine similarity
- Q-merged = Σ(q_i × sim_i) / Σ(sim_i) per layer per experience
- κ (stiffness) = 1/variance(rewards) — compression readiness signal
- Originals marked as "merged" via lifecycle transitions
- Merged memory gets "confirmed" status and inherits best metadata

New files:
- openexp/core/compaction.py — clustering, merging, Q computation
- tests/test_compaction.py — 16 tests for all core functions

CLI: `openexp compact --dry-run [--max-distance 0.25] [--project X]`

Add reward_log.jsonl as append-only cold storage for complete reward
event context. Each reward event gets a unique reward_id (rwd_<8hex>)
that links L2 summary → L3 full record.

Three levels of Q-value explainability:
- L1: Q-value scalar (instant ranking)
- L2: reward_contexts with [rwd_...] pointers (quick inspection)
- L3: cold storage with full observations, predictions, breakdowns

All three reward paths (session, prediction, business) now generate
reward_ids and write to cold storage. New MCP tool reward_detail
for on-demand L3 access. calibrate_experience_q also writes L3.

- explain_q MCP tool aggregates all L4 explanations for a memory
- All reward paths now produce L4 explanations in cold storage
- 50+ new tests for explanation and reward context

Two critical bugs in the Q-learning reward loop:

1. Session reward was computed from ALL observations across ALL sessions
   (showing "67 commits, 154 PRs" = lifetime cumulative stats). Now filters
   to only observations matching the current session_id.

2. Reward was applied to ALL newly ingested memories (2,721 at once)
   instead of only the 5-10 memories recalled at session start. Now uses
   reward_retrieved_memories() exclusively — the correct closed-loop path.

These bugs made Q-values meaningless (99.8% at identical Q=0.12).
Q-cache has been reset to allow clean re-learning.

Observations are now automatically matched against CRM company names
during ingestion. This enables the CRM resolver to reward memories
when deals progress (e.g., invoiced→paid), closing the business
outcome feedback loop.

Protected memories never receive negative Q-value rewards — their score
can only go up. Use for identity, core decisions, safety rules, and
critical knowledge that should never decay.

- QValueUpdater.update() and update_all_layers() skip negative rewards
  for protected memories (still log visits and context)
- New MCP tool `protect_memory` to protect/unprotect memories

When openexp modules are imported, ANTHROPIC_API_KEY gets set via .env/config.
claude -p then uses API credits (empty) instead of Max subscription, causing
exit=1 with "Credit balance is too low". Stripping the key forces Max mode.

* docs: full reward system audit — 5 paths verified against code

Added reward-audit-2026-04-08.md with complete code audit of all 5
reward paths (session, prediction, business, calibration, retrospective).
Every claim verified with file:line references.

Key findings: session rewards too small to influence ranking, prediction
path unused (0 real predictions), retrospective 95% wasted on test
fixtures leaked into Q-cache, calibration race condition (save_delta vs
save). Updated storage-system.md to document Path 5 (retrospective).

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: remove session reward heuristic (Path 1)

Session reward scored sessions by tool calls (commits +0.3, PRs +0.2)
but didn't reflect real session value. Max Q-value produced was 0.031.
Ivan's decision: Q-learning should rely on outcome-based rewards only
(prediction, CRM business, calibration, retrospective).

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: add Qdrant existence check in retrospective apply_adjustments

Previously, retrospective only validated memory_id against Q-cache.
Test fixture IDs (mem-0001 etc.) passed validation and received 95%
of all retrospective rewards. Now validates against Qdrant with
graceful fallback if Qdrant is unavailable.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: persist calibration Q-values immediately via save_delta

Calibration previously relied on atexit handler to persist changes.
If retrospective ran save() between calibration and process exit,
calibration values were overwritten. Now save_delta() runs immediately
after each calibration, ensuring the delta file exists before any
concurrent writer can overwrite it.

* refactor: replace observation pipeline with full transcript ingest

Kill the PostToolUse hook and observation pipeline that stored useless
"Edited arena.py" entries. Replace with transcript.py that parses
Claude Code JSONL transcripts and stores every user/assistant message
in Qdrant. Add v2 backlog tracker.

- Delete: observation.py, filters.py, reward.py, session_summary.py,
  post-tool-use.sh and their tests
- Add: ingest/transcript.py (parse + embed + batch upsert)
- Wire transcript ingest into session-end.sh (Phase 2d)
- Rewrite cli.py cmd_ingest to use transcript pipeline
- Clean ingest/__init__.py (remove dead ingest_session)
- Add backlog.yaml + backlog_cli.py for v2 project tracking

- Topic mapping: per-chunk topic extraction via LLM (170 topics)
- Thread grouping: cross-chunk topic merge into work threads (36 threads)
- Experience extraction: Opus labels each thread with context→actions→outcome triplets
- Batch labeling: script to process all threads (269 experience labels produced)
- add_experience() in direct_search: store labels in Qdrant with search-optimized embedding
- Reduce MCP tools from 16 to 5 (search_memory, add_memory, log_prediction, log_outcome, memory_stats)
- Enable Q-value weight in scoring (0% → 10%)
- CLI commands: openexp chunk, openexp topics

…ault

Qdrant official image runs as root (UID 0) by default. The --user 1000:1000
flag was causing permission issues with the named volume storage because:
- The container's /qdrant/storage is owned by root
- Forcing UID 1000 denied write access to storage directory

Running without --user allows the container to use its default root user,
which has proper permissions for the named volume.

Add fallback `|| echo "not_found"` to collection existence check.
Without this, the script would silently exit with code 22 when curl
fails (e.g., 404 Not Found) or jq encounters null/invalid input.

The || fallback ensures COLLECTION_EXISTS is always set to a valid
string, allowing the conditional logic to proceed correctly.

Fix two jq-related errors during Claude Code hooks registration:

1. Null containment error: Change .command | contains() to
   (.command // "") | contains() to handle hook items without
   command field.

2. Array iteration error: Change any(.[]; ...) to
   any(.hooks.SessionStart[]; ...) and use += instead of . + [...]
   to properly append to hook arrays.

Fixes: 'null cannot have containment checked' and
'object and array cannot be added' errors.
