## CI Health Sweep (2026-06-11)

**Task**: Analyze failing CI, open PRs/issues, and missing implementation; document GOAP + ADR.

**Findings**:
- **Open PRs**: 1 — PR #616 (`perf(encoder): optimize cosine similarity`, Jules bot). ❌ CI red.
  - Root cause: `clippy::await_holding_lock` — PR holds a `parking_lot::Mutex` guard across `.await` in `memory-mcp/src/bin/server_impl/storage.rs` tests. Cascades to CI/Coverage/Security/Perf via `wait-on-check`. `main` is clean.
  - PR is cut from a stale base and deletes recent `plans/*` files (would regress docs).
- **Open Issues**: none.
- **Nightly Full Tests (main)**: ❌ — `should_scale_processing_with_different_worker_counts` TIMEOUT (120s, `#[ignore]` slow test); regular-tests exit-95 = runner disk-space (infra); mutation testing = 2h ceiling.
- **Missing impl**: WG-156–162 stubs still present (e.g. `query_hits: 0 // Not yet implemented`); tracked in `GOAP_PRE_EXISTING_ISSUES_FOLLOWUP_2026-06-09.md`.

**Plan Documents**:
- `plans/GOAP_CI_ANALYSIS_2026-06-11.md` — GOAP action plan (A1–A5)
- `plans/adr/ADR-057-CI-Health-PR616-Nightly-Timeout.md` — decision record
- `plans/CODE_CHANGES_CI_REMEDIATION_2026-06-11.md` — detailed before/after code changes

### v0.1.32 Feature Addition — PR #611 (2026-06-06)

**Issue**: [#610](https://github.com/d-o-hub/rust-self-learning-memory/issues/610) — feat(turso): expose local/offline mode  
**PR**: [#611](https://github.com/d-o-hub/rust-self-learning-memory/pull/611) — Expose local/offline mode as a first-class config path  
**ADR**: ADR-056 — Local Storage No Connection Pooling  
**Branch**: `feat/turso-local-mode-12832947082971821257`  
**CI Status (2026-06-08)**: 🔴 4 checks failing

| Check | Status | Root Cause |
|-------|--------|------------|
| Tests | ❌ FAILURE | SIGSEGV in turso relationship tests with `keepalive-pool` feature enabled |
| Multi-Platform (ubuntu) | ❌ FAILURE | Same SIGSEGV |
| Multi-Platform (macos) | ❌ FAILURE | Same SIGSEGV |
| Code Coverage Analysis | ❌ FAILURE | CLI `test_cli_help_output` snapshot mismatch |

**Root cause** (documented in `GOAP_PR611_CI_FIX_2026-06-09.md`):
- `new_local`/`new_in_memory` routed through `TursoConfig::default()` which has `enable_pooling=true` + `enable_keepalive=true`
- Background task holding libsql connections drops outside `#[tokio::test]` runtime → SIGSEGV
- Fix: `local_config()` with `enable_pooling=false`, `enable_keepalive=false`
- Snapshot mismatch: clap trailing whitespace stripped from hand-edited `.snap` file; fix via `cargo insta accept`

**Fix status**: Documented (2026-06-09), not yet applied to branch.

**Next action**: Apply fixes from `plans/GOAP_PR611_CI_FIX_2026-06-09.md` to `feat/turso-local-mode-12832947082971821257` and push.

## v0.1.31 Sprint (Released ✅)

### GOAP Analysis (2026-04-20)

**Primary Goal**: Reduce CPU usage and prompt/token usage via CPU-local retrieval tiers (CSM integration), cascading query pipeline, and skills consolidation — while keeping release/package truth sources accurate ahead of the `0.1.31` version bump.

**Constraints**:
- Time: Normal
- Resources: All agents available
- Dependencies: Release/package truth must stay aligned before the `0.1.31` bump

**Complexity Level**: Complex (4+ agents, mixed execution)

**Strategy**: Hybrid (Phase 0 sequential → CPU/token work parallelized → research follow-up deferred)

### GOAP Skill Stack

- **Planning/coordination**: `goap-agent`, `agent-coordination`
- **CPU work**: `performance`, `feature-implement`, `debug-troubleshoot`
- **CSM integration**: `feature-implement`, `performance`, `test-runner`
- **Token/docs work**: `agents-update`, `memory-context`, `learn`
- **Validation**: `code-quality`, `test-runner`, `architecture-validation`

### Execution Pattern

- **Analyze**: verify release/package truth, cache hot paths, token-heavy context assembly
- **Decompose**: split work into release/package, CPU efficiency, token efficiency, and deferred research upgrades
- **Coordinate**: run CPU and token tasks in parallel after truth-source alignment
- **Validate**: require benchmarks or measurable budget reductions before version bump

### Phase 0: Release & Package Truth (Sequential)

| Task | WG | Status | Owner |
|------|----|--------|-------|
| Verify v0.1.30 release/package parity | WG-111 | ✅ Complete | github-release-best-practices |

- **Gate 1.5** (after Phase 1.5): BM25+HDC retrieval tested, cascading pipeline passes integration tests, API call count reduced
- **Gate 2** (after Phase 1-2): CPU hot paths benchmarked, token budget reduced, all tests pass
- **Gate 3** (after Phase 3): retrieval upgrades validated without coverage regressions

### Recommended Skill Invocation Order

1. `goap-agent`
2. `agent-coordination`
3. `performance` or `feature-implement` depending on work item
4. `agents-update` for high-frequency doc/skill compaction
5. `code-quality` and `test-runner` before closing a work group

## DyMoE Feature Impact Analysis (Issue #419)

### Architecture Touchpoints

| Component | File | Current Behavior | DyMoE Change |
|-----------|------|------------------|-------------|
| Pattern extraction | `memory/learning.rs` | Extracts & stores all patterns unconditionally | Add affinity gate before `store_pattern` |
| Effectiveness tracker | `patterns/effectiveness/calculator.rs` | Uniform decay by min_effectiveness (0.3) | Add `affinity_clarity` as second gating dimension |
| Reward scoring | `reward/mod.rs` | Single composite `RewardScore` (total/base/efficiency/etc.) | Add `stability_score` + `novelty_score` fields |
| Pattern types | `pattern/types.rs` | `PatternEffectiveness` tracks success_rate + avg_reward_delta | No schema change needed |
| Hybrid extractor | `patterns/extractors/hybrid.rs` | Runs 4 extractors, clusters, deduplicates | Insert affinity classifier before clustering |
| Cosine similarity | `embeddings/similarity.rs` | `cosine_similarity(a, b) -> f32` | Reuse existing — no new dependency |
| Recommendation | `memory/pattern_search/recommendation.rs` | Multi-signal scoring (semantic + recency + success) | Wire `EpisodeAssignmentGuard` into scoring |

### Impact Assessment

| Change | LOC Estimate | Risk | Files Modified | New Files |
|--------|-------------|------|---------------|-----------|
| `EpisodeAssignmentGuard` (WG-089 part 2) | ~50 | Low | `effectiveness/calculator.rs` | 0 |
| `PatternAffinityClassifier` (WG-089 part 1) | ~80 | Medium | `learning.rs`, `hybrid.rs` | `patterns/affinity.rs` |
| `DualRewardScore` (WG-090) | ~60 | Low | `reward/mod.rs` | 0 |
| DB schema migration | ~20 | Low | turso schema | 0 |
| Tests | ~200 | None | — | `tests/dymoe_*.rs` |
| **Total** | **~410** | **Medium** | **4–5** | **1–2** |

### Recommended Execution Order (from issue #419)
1. `EpisodeAssignmentGuard` — smallest diff, highest leverage
2. `PatternAffinityClassifier` — depends on cosine_similarity infra (already exists)
3. `DualRewardScore` — extends existing `RewardScore`, backward-compatible

### Key Finding
The existing `cosine_similarity` function in `embeddings/similarity.rs` can be reused directly for `compute_drel()`. No new embedding infrastructure needed. The `PatternEffectiveness` already tracks `success_rate` which maps to the `success_rate` dimension of the `EpisodeAssignmentGuard`.

## Self-Learnings (Consolidated)

Patterns extracted from v0.1.17–v0.1.27 sprint history (34 sessions, 234 msgs, 97 commits):

### API / Dependency Changes
- **redb 3.x**: `begin_read()` is on the `ReadableDatabase` trait — import accordingly
- **rand 0.10**: `thread_rng()` → `rand::rng()`, `gen()` → `random()`, `gen_range()` → `random_range()`

### Development Workflow
- **Turso local dev**: Use `turso dev` — no auth token needed
- **Doctest quality**: New features must have tested doctests before merge
- **File size invariant**: Templates extraction prevents LOC growth (≤500 LOC per file)
- **Integration tests**: Feature implementation without integration tests leaves gaps
- **Documentation sync**: ROADMAP / CURRENT must stay in sync with releases
- **Plan document drift**: Always verify metrics by running actual commands, not trusting stale docs

### CI / GitHub
- **PR supersession**: Track supersession chains (e.g., #388 → #389 → #391) to avoid referencing stale PRs
- **codecov/patch**: Not a required CI check — configure thresholds in `codecov.yml`, don't block merges
- **Jules PRs**: Reconcile external agent PRs before planning more work — they may implement "pending" items

### Quality Gates
- **Ignored test ceiling**: Monitor the 125 ceiling metric; actual count can creep close
- **Tool selection**: Target Bash:Grep ratio of 2:1 (historical 17:1 indicates over-reliance on shell)
- **Atomic commits**: One change per commit — 5 excessive_changes instances in early sprints
- **Wrong approach**: Read 3+ source files before implementing — 8 instances of proceeding without patterns
