Subject: [PATCH 1/4] perf(hyperdim): optimize serialization via single memcpy

Optimize HVec10240 serialization and deserialization by replacing
iterative word-by-word loops with a single memcpy on little-endian
platforms. This eliminates 80 bounds checks and word conversion
calls per operation.

hvec_to_bytes: 177ns -> 94ns (47% improvement)
hvec_from_bytes: 51ns -> 48ns (6% improvement)

+Excellent scalability: 500x more concepts only 3x slower.

 ## Workflow
 
 ### 1. Save Baseline Before Changes
 ```bash
 export CARGO_TERM_PROGRESS_WHEN=never
-cargo bench --bench benchmark -- --save-baseline before
-```
-
-### 2. Compare Against Baseline
-```bash
-cargo bench --bench benchmark -- --baseline before
-```
-
-### 3. Interpret Results
-- Green = faster, Red = slower
-- Changes > 5% in hot paths require investigation
-
-## SIMD Optimization
-
-```rust
-#[cfg(feature = "simd")]
-use std::simd::u128x2;
-
-pub fn cosine_similarity_simd(&self, other: &Self) -> f32 {
-    // Use u128x2 for parallel operations
-    // Fall back to scalar for WASM/non-SIMD targets
-}
+cargo bench --bench benchmark -- --save-baseline before 2>&1 | grep -E "(^test |time:|Benchmark|bench_|[0-9]+\.[0-9]+ µs)" | tail -30
 ```
 
-Always provide scalar fallback for non-SIMD targets. Gate with feature flags.
-
-## Connection Pooling
-
-Use `deadpool` for async connection pooling, gated for remote Turso only.
-Keep per-operation model for local SQLite.
+### 2. Make Changes
 
-## Batch API Pattern
-
-```rust
-pub async fn inject_concepts(&self, concepts: &[(String, HVec10240)]) -> Result<()> {
-    // Validate all inputs first → Batch insert → Single transaction for DB
-}
+### 3. Compare Against Baseline
+```bash
+export CARGO_TERM_PROGRESS_WHEN=never
+cargo bench --bench benchmark -- --baseline before 2>&1 | grep -E "(time:|Benchmark|bench_|change:)" | tail -30
 ```
 
-## Caching Pattern
-- Prefer cached values as `Arc<[T]>` for cheap `Arc::clone` hits
-- Avoid keying caches via temporary `Vec` materializations; hash fixed-size words/arrays directly
-- Cache hit rate target: >80% for repeated access patterns
+### 4. Interpret Results
+- Look for `time: [lower upper]` in criterion output.
+- Green = faster, Red = slower.
+- Changes > 5% in hot paths require investigation.
 
 ## Adding a New Benchmark
 Edit `benches/benchmark.rs`. Follow existing patterns:
 ```rust
 fn bench_my_operation(c: &mut Criterion) {
+    // Setup outside the closure
     let data = prepare_data();
+
     c.bench_function("my_operation", |b| {
-        b.iter(|| my_operation(black_box(&data)))
+        b.iter(|| {
+            // Only the measured code here
+            black_box(my_operation(black_box(&data)))
+        })
     });
 }
 ```
 Add to `criterion_group!` at the bottom.
 
 ## Gotchas
-- Never `--baseline` without first `--save-baseline` with the same name
-- Don't capture mutable state by reference in criterion closures
-- Use `black_box()` on inputs AND outputs to prevent dead-code elimination
-- Reservoir benchmarks use `new_seeded(..., 42)` for reproducibility
-
-## LOC Constraint
-All files must remain ≤ 500 lines. Refactor to new modules if needed.

+## Loop Parameters
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `MAX_ITERATIONS` | 10 | Maximum refinement cycles |
+| `COVERAGE_THRESHOLD` | 80% | Minimum coverage to accept |
+| `BENCH_BASELINE` | main | Branch to compare benchmarks |
+
+## Step-by-Step Execution
+
+### Phase 1: RED - Identify Failures
+
+```bash
+# Run full test suite
+cargo test --all-features --quiet 2>&1 | tee test-output.txt
+
+# Parse failures
+grep -E "^test .* FAILED" test-output.txt
+
+# For specific test debugging
+cargo test --test <test_name> -- --nocapture
+```
+
+### Phase 2: GREEN - Apply Fix
+
+1. Analyze failure output
+2. Identify root cause (not symptom)
+3. Apply minimal fix to make test pass
+4. Do NOT refactor yet
+
+```bash
+# Quick validation
+cargo check --message-format=short
+cargo test --all-features --quiet
+```
+
+### Phase 3: REFACTOR - Optimize
+
+Once tests pass:
+1. Identify code smells
+2. Apply refactoring patterns
+3. Run tests after each change
+4. Verify no regression
+
+### Phase 4: VALIDATE
+
+```bash
+# Full gate sequence
+./scripts/validate.sh
+
+# Coverage check (if configured)
+cargo tarpaulin --all-features --out Stdout
+
+# Benchmark comparison
+cargo bench --bench benchmark -- --baseline main
+```
+
+## Failure Categories
+
+| Category | Pattern | Approach |
+|----------|---------|----------|
+| **Logic error** | Assertion mismatch | Fix implementation logic |
+| **Type error** | Compilation failure | Fix types, add conversions |
+| **Timeout** | Test exceeds limit | Optimize algorithm |
+| **Race condition** | Flaky test | Add synchronization |
+| **Environment** | Missing dependency | Fix setup, add config |
+
+## Iteration Tracking
+
+Track each iteration:
+
+| Iteration | Phase | Action | Result |
+|-----------|-------|--------|--------|
+| 1 | RED | Run tests | 3 failures |
+| 1 | GREEN | Fix imports | Passes |
+| 2 | REFACTOR | Extract function | Passes |
+| 3 | VALIDATE | Coverage check | 85% covered |
+
+## Exit Criteria
+
+Stop when ALL conditions are met:
+- [ ] All tests pass
+- [ ] Coverage meets threshold
+- [ ] No clippy warnings
+- [ ] No performance regression (>10%)
+- [ ] LOC gates satisfied
+
+## Example Workflow
+
+```
+User: "Refactor the reservoir module"
+
+Agent: [Iterative Refinement activated]
+Iteration 1:
+  RED: cargo test → 2 failures in reservoir
+  GREEN: Fix borrow checker issue
+  Result: Tests pass
+
+Iteration 2:
+  REFACTOR: Extract metrics to separate file
+  RED: cargo test → 0 failures
+  Result: Still green
+
+Iteration 3:
+  VALIDATE: ./scripts/validate.sh
+  Result: All gates pass, 92% coverage
+
+Final: Refactoring complete after 3 iterations
+```

+- Skipping failing tests instead of fixing
+- Large refactors without incremental commits
+- Ignoring performance regressions

+description: "SIMD optimization, connection pooling, batch APIs, and caching. Use when improving throughput or reducing latency."
+---
+
+# Swarm: Performance
+
+## Workflow
+
+1. Profile current performance with `cargo bench --bench benchmark`
+2. Identify hot path from flamegraph or benchmark results
+3. Implement optimization behind feature flag if experimental
+4. Benchmark before/after with criterion baseline
+5. Ensure SIMD has scalar fallback for non-SIMD targets
+6. Run all gates before claiming improvement
+
+## SIMD Implementation
+
+```rust
+#[cfg(feature = "simd")]
+use std::simd::u128x2;
+
+pub fn cosine_similarity_simd(&self, other: &Self) -> f32 {
+    // Use u128x2 for parallel operations
+    // Fall back to scalar for WASM/non-SIMD targets
+}
+```
+
+## Connection Pooling
+
+Use `deadpool` for async connection pooling, gated for remote Turso only.
+Keep per-operation model for local SQLite.
+
+## Batch API Pattern
+
+```rust
+pub async fn inject_concepts(
+    &self,
+    concepts: &[(String, HVec10240)]
+) -> Result<()> {
+    // Validate all inputs first
+    // Batch insert to singularity
+    // Batch save to persistence
+    // Single transaction for DB
+}
+```
+
+## Caching Pattern
+
+- Prefer cached values stored as `Arc<[T]>` so cache hits are cheap (`Arc::clone`).
+- Avoid keying caches via temporary `Vec` materializations; hash fixed-size words/arrays directly.
+
+## Performance Targets
+
+- Batch similarity: 10k ops/ms
+- Connection pool: <1ms acquire time
+- Cache hit rate: >80% for repeated access patterns
+- Reservoir step: maintain <100μs @ 50k
+
+## Test Files
+
+Run performance tests:
+
+```bash
+cargo test --test <test_name>
+```
+
+## LOC Constraint
+
+All files must remain ≤ 500 lines. Refactor to new modules if needed.

+# Swarm: Testing & Quality
+
+## Test Files
+
+This project uses separate integration test files in `tests/`. Run specific tests:
+
+```bash
+cargo test --test <test_file_name>
+```
+
+## Workflow
+
+1. Check current test coverage in `tests/` directory
+2. Identify properties to test (invariants, roundtrips, bounds)
+3. Add `proptest` dependency to `Cargo.toml`
+4. Create new test file in `tests/` with property tests
+5. Set up `fuzz/` directory with cargo-fuzz targets
+6. Add edge case tests to separate test files
+7. Run validation gates
+
+## Key Properties to Test
+
+### HVec10240
+
+- `from_bytes(to_bytes(v)) == v` (roundtrip)
+- `cosine_similarity(v, v) == 1.0` (self-similarity)
+- `cosine_similarity(a, b) == cosine_similarity(b, a)` (symmetry)
+- `cosine_similarity(a, b)` in `[-1.0, 1.0]` (bounds)
+
+### Reservoir
+
+- `reset()` clears state to zeros
+- `step()` with same input produces same output after `reset()`
+- `to_hypervector()` fails if `size < 10240`
+
+### Persistence
+
+- `save_concept(c); load_concept(c.id) == Some(c)` (roundtrip)
+- `delete_concept(id); load_concept(id) == None` (deletion)
+- FK constraints reject invalid associations
+
+## Commands
+
+```bash
+# Run property tests
+
+cargo test --test <test_name>
+
+# Run fuzzer (requires cargo-fuzz)
+
+cargo fuzz run fuzz_hvec_from_bytes
+```
+
+## LOC Constraint
+
+All files must remain ≤ 500 lines. Create new test files rather than inflating existing ones.

 ## Mission
 Build and maintain `chaotic_semantic_memory` as a production Rust crate for AI memory systems.
 
-## Session Workflow — PRE-FLIGHT → EXECUTE → VERIFY
-
-### PRE-FLIGHT — Understand before acting
-1. Load state: `@plans/GOAP_STATE.md` (action_last_completed, module LOC)
-2. Review uncommitted changes: `git status --short && git diff HEAD`
-3. LOC gate pre-check: `find src -name '*.rs' -exec wc -l {} + | sort -rn | head -20` (all ≤ 500)
-4. CI baseline: `gh run list --workflow=ci.yml --limit 3`
-
-### EXECUTE — Read, plan, implement
-1. Read target files + neighbors before editing
-2. For 3+ step tasks: plan in `plans/`, document approach, get approval
-3. Match existing style, naming, conventions — see `@.agents/skills/rust-development/reference/codebase-patterns.md`
-4. After changes: `./scripts/validate.sh` (first run: `--save-baseline` for baseline-aware mode)
-
-### VERIFY — Gates before completion
-1. `./scripts/validate.sh` — all quality gates in one command (baseline-aware)
-2. Fix ALL new issues (pre-existing errors filtered by baseline; new regressions block merge)
-3. Atomic commit: `./scripts/ai-commit.sh`
-4. Branch → PR → CI: `git push origin <branch>`, `gh pr create`, `gh pr checks --watch`
-5. Update `@plans/GOAP_STATE.md` with `action_last_completed` and new counts
+---
+
+## Workflow (REQUIRED for Every Session)
+
+**This workflow MUST be followed for every coding task. Skipping steps causes regressions.**
+
+### Phase 1: Context Load (WHAT)
+
+1. **Read state files first** — Load current world state before any work:
+   - `@plans/GOAP_STATE.md` — Current world state, completed phases, module LOC
+   - `@plans/ACTIONS.md` — Queued actions and their preconditions
+
+2. **Review ALL uncommitted changes** — Never start implementation without knowing the full scope:
+   ```bash
+   git status --short           # List ALL modified/untracked files
+   git diff HEAD                # Review content of pending changes
+   ```
+   - If unrelated changes exist, either commit them first or explicitly scope them out
+   - Document which pending changes are intentionally excluded from this session
+
+3. **Run proactive LOC gate check** — Pre-existing violations cascade on commit, wasting iterations:
+   ```bash
+   find src -name '*.rs' -exec wc -l {} + | sort -rn | head -20
+   # Verify every file is ≤ 500 LOC. Fix violations BEFORE starting work.
+   ```
+
+4. **Understand the codebase structure** — Know where files live before editing:
+   - Core modules: `src/singularity.rs`, `src/reservoir.rs`, `src/framework.rs`
+   - Persistence: `src/persistence.rs`, `src/persistence_ops.rs`
+   - Retrieval: `src/retrieval/bm25.rs`, `src/retrieval/hybrid.rs`
+   - Bridge: `src/semantic_bridge.rs`, `src/bridge_retrieval.rs`
+   - CLI: `src/cli/commands/*.rs`
+
+5. **Check CI status** — Verify baseline before changes:
+   ```bash
+   gh run list --workflow=ci.yml --limit 3
+   ```
+
+### Phase 2: Planning (WHY)
+
+6. **Plan before implementing** — For non-trivial tasks (3+ steps):
+   - Explore codebase before proposing changes
+   - Identify affected files and dependencies
+   - Document approach in `plans/` directory
+   - Get user approval before implementation
+   - **TRIZ Integration**: Use `triz-analysis` skill for architectural decisions
+   - **Problem Solving**: Use `triz-solver` skill when stuck on complex problems
+
+7. **Use parallel execution for complex changes** — For multi-file tasks:
+   - Create task list for each subtask
+   - Spawn specialized workers with clear prompts
+   - Assign tasks and monitor progress
+   - Clean up resources after completion
+
+### Phase 3: Implementation (HOW)
+
+8. **Edit files with precision** — Never bulk-edit without reading first:
+   - Read before editing — understand existing code
+   - Match existing style, naming, patterns
+   - Preserve comments and docstrings unless explicitly removing
+
+9. **Run validation gates after changes** — Verify before proceeding:
+   ```bash
+   cargo check --quiet                      # Compile check
+   cargo test --all-features --quiet        # Unit + integration tests
+   cargo fmt --check --quiet                # Format check
+   cargo clippy --quiet -- -D warnings      # Lint check (includes dead_code, unused_imports, unused_variables)
+   ```
+
+10. **Coverage validation** — Ensure test coverage meets target:
+   ```bash
+   # Calculate test:source ratio
+   test_loc=$(wc -l tests/*.rs | tail -1 | awk '{print $1}')
+   src_loc=$(wc -l src/*.rs src/**/*.rs | tail -1 | awk '{print $1}')
+   ratio=$((test_loc * 100 / src_loc))
+   # Target: >= 90% coverage
+   ```
+
+11. **Real usage validation** — Test production scenarios:
+   ```bash
+   # CLI workflow test
+   csm inject test-1 --database /tmp/validate.db
+   csm probe test-1 -k 5 --database /tmp/validate.db
+   csm export -o /tmp/validate.json --database /tmp/validate.db
+   csm import /tmp/validate.json --database /tmp/validate.db
+   rm /tmp/validate.db /tmp/validate.json
+
+   # Skill-memory integration
+   ls -la .agents/csm-memory/skill-memory.db  # Verify db exists
+   ```
+
+12. **Update state after completion** — Record what changed:
+   - Update `GOAP_STATE.md`: `action_last_completed`, module LOC, test counts
+   - Add learnings to `progress/LEARNINGS.md` if new patterns discovered
+
+### Phase 4: Verification (Compound Engineering)
+
+13. **Run full validation before claiming completion**:
+   ```bash
+   ./scripts/validate.sh                    # All gates in one command
+   ```
+
+14. **If errors occur, encode corrections** — Compound engineering principle:
+    - Fix the immediate error
+    - Add rule/constraint to prevent recurrence
+    - Update AGENTS.md or hard-constraints.md if systemic
+
+### Phase 5: Atomic Commit & CI Gate (GOAP Orchestration)
+
+15. **Create feature branch FIRST** — `main` is protected, never commit directly:
+    ```bash
+    git checkout -b <type>/<scope>-<description>
+    # Examples: test/inline-tests-clippy-config, fix/persistence-fk, feat/reservoir-simd
+    ```
+
+16. **Atomic commits** — One logical change per commit, never mix unrelated changes:
+    ```bash
+    git add src/singularity.rs src/singularity_cache.rs
+    git commit -m "feat(singularity): add similarity cache"
+    ```
+
+17. **Push branch and create PR** — Never push directly to `main`:
+    ```bash
+    git push origin <branch>
+    gh pr create --title "<type>(<scope>): <summary>" --body "..."
+    gh pr checks --watch  # Wait for CI to pass
+    ```
+
+18. **Merge after CI passes** — Only merge when all checks are green:
+    ```bash
+    gh pr merge  # Squash merge preferred
+    ```
+
+19. **Fix ALL issues (including pre-existing)** — CI must pass completely:
+    - New failures: Fix immediately
+    - Pre-existing warnings: Fix before claiming completion
+    - Use `goap-planning` skill to track fix actions in GOAP_STATE
+    - Update `action_last_completed` and `world_state` after each fix
+
+20. **Document in GOAP_STATE** — Record completion state:
+    ```yaml
+    world_state:
+      action_last_completed: <action_name>
+      ci_all_checks_passed: true
+      tests_count: <new_count>
+    ```
+
+---

 ## 8 Core Rules
-1. **Always read before editing** — never guess file contents
-2. **Stay under context limits** — each instruction must earn its place
-3. **Validation gates mandatory** — `./scripts/validate.sh` before claiming completion
-4. **Reference, don't duplicate** — point to source files via `@path/to/file`
-5. **Plan before implementing** — for tasks with 3+ steps
-6. **Encode errors immediately** — every correction becomes a rule in `agents-docs/hard-constraints.md`
-7. **Never push directly to `main`** — branch → commit → PR → squash merge after CI
-8. **CI passes for your changes** — baseline filters pre-existing errors; new regressions block merge before PR

-## Coding Standards (DeepSource Parity)
-See `@.agents/skills/rust-development/reference/codebase-patterns.md` for full conventions.
-- `Default::default()` constructs struct directly; `new()` delegates to `default()` (not vice-versa)
-- Use `.map_or()` / `.is_some_and()` instead of `.map().unwrap_or()`

+
+1. **Always read before editing** — Never guess file contents.
+
+2. **Stay under context limits** — Each instruction must earn its place.
+
+3. **Hooks for deterministic enforcement** — Validation gates are mandatory.
+
+4. **Use `@imports` for modularity** — Reference files via `@path/to/file` syntax.

+5. **Plan before implementing** — For tasks with 3+ steps.
+
+6. **Update monthly, encode errors immediately** — Every correction becomes a rule.

+
+---
+
+## DeepSource Parity (Coding Standards)
+
+These patterns mirror DeepSource's Rust analyzer rules. Violations block CI.
+
+### DO: Construct directly in `Default::default()`
+
+```rust
+// ✅ CORRECT: default() constructs the struct directly; new() delegates to default()
+impl Default for FrameworkBuilder {
+    fn default() -> Self {
+        Self {
+            config: FrameworkConfig::default(),
+            db_path: None,
+            // ...
+        }
+    }
+}
+
+impl FrameworkBuilder {
+    pub fn new() -> Self {
+        Self::default()
+    }
+}
+
+// ❌ WRONG: default() calling Self::new() triggers DeepSource BUG_RISK
+impl Default for FrameworkBuilder {
+    fn default() -> Self {
+        Self::new()  // DeepSource: "Found call returning Self in default()"
+    }
+}
+```
+
+### DO: Use `.map_or()` / `.is_some_and()` instead of `.map().unwrap_or()`
+
+```rust
+// ✅ CORRECT
+concepts.get(id).is_some_and(|c| filter.matches(&c.metadata))
+value.map_or_else(|| default(), |s| s.to_string())
+
+// ❌ WRONG: triggers DeepSource ANTI_PATTERN + clippy::map_unwrap_or
+concepts.get(id).map(|c| filter.matches(&c.metadata)).unwrap_or(false)
+value.map(|s| s.to_string()).unwrap_or_else(|| default())
+```
+
+### Clippy Lints Enforcing These
+
+| Pattern | Clippy Lint | Active? |
+|---------|-------------|---------|
+| `.map(f).unwrap_or(g)` | `clippy::map_unwrap_or` (pedantic) | ✅ Promoted to `warn` in Cargo.toml |
+| `.map_or(false, f)` | `clippy::unnecessary_map_or` (in `all`) | ✅ Implied by `-D warnings` |
+| `Self::new()` in `default()` | No clippy equivalent | 📋 Documented above |
+
+---
 
 ## Hard Constraints

+## Release Safety Requirements
+
+**CRITICAL: Never release with failing CI. The release workflow now has a guardrail that waits for CI to pass.**
+
+### Artifact Selection (REQUIRED)
 
-## Release Safety
-See `@.agents/skills/release-management/SKILL.md`. Critical: never release with failing CI. `./scripts/validate.sh` passes on all platforms before tag.
+Before validating, installing, or publishing, identify the correct channel:
+- **Rust Library:** `chaotic_semantic_memory` (crates.io / cargo)
+- **JS/WASM Library:** `@d-o-hub/chaotic_semantic_memory` (npm WASM)
+- **CLI Tool:** `@d-o-hub/csm` (npm CLI)
 
+Refer to the `dist-channel-selection` skill for canonical commands.
+
+### Pre-Release Checklist (MANDATORY)
+
+1. **Verify CI passes on all platforms**:
+   ```bash
+   gh run list --workflow=ci.yml --limit 3
+   gh run view --log  # Check all jobs: macos-arm64, windows-x64, linux
+   ```
+
+2. **Ensure Cargo.lock is synchronized**:
+   ```bash
+   cargo build --release  # Regenerates Cargo.lock after version bump
+   git add Cargo.lock     # Must be committed with version changes
+   ```
+
+3. **Check existing releases**:
+   ```bash
+   gh release list --limit 5
+   gh release view --json tagName,isLatest
+   ```
+
+4. **Validate changelog entry exists**:
+   ```bash
+   grep -q "^## \[${VERSION}\]" CHANGELOG.md
+   ```
+
+### Version Bump Workflow
+
+1. Update `Cargo.toml` version
+2. Update `wasm/package.json` version
+3. Update `CHANGELOG.md` with new section
+4. Run `cargo build --release` to sync Cargo.lock
+5. Commit all version files together (atomic)
+6. Push and wait for CI to pass
+7. Only then create tag/release
+
+### Platform-Specific Considerations
+
+- **macOS arm64**: NEON SIMD intrinsics require explicit unsafe blocks
+- **Windows x64**: CI uses `--locked` flag, Cargo.lock must match Cargo.toml
+- **WASM**: Size gate checks library (~870KB), not CLI binary (~5KB)
+

 ## What Works
-1. Systematic codebase analysis before planning
-2. ADRs for every non-trivial architectural change
-3. Domain-specific debugging skills over generic boilerplate
-4. Executable scripts in skills — agents can run them directly
-5. Seeded RNG (`StdRng::seed_from_u64(42)`) for deterministic tests
-6. CI-enforced version synchronization
+
+1. Systematic codebase analysis before planning — found more real issues than GOAP state listed
+2. Using oracle for deep code review across all modules simultaneously
+3. Writing ADRs for every non-trivial architectural change before implementation
+4. Creating domain-specific debugging skills rather than generic boilerplate
+5. Adding executable scripts to skills — agent can run them directly
+6. Treating GOAP state booleans as executable acceptance criteria
+7. Using seeded RNG (`StdRng::seed_from_u64(42)`) in tests for determinism
+8. Migrating to `libsql::Builder` to remove deprecated API usage
+9. Enabling `PRAGMA foreign_keys = ON` per-connection for deterministic FK behavior
+10. CI-enforced version synchronization — catches drift before merge
 
 ## Technical Insights
-- Dense `Array2<f32>` for 50k×50k reservoir is infeasible (~10 GB). CSR with k=64 → ~25 MB.
-- `HVec10240::permute()` with `bit_shift == 0` causes UB — must guard
-- `Arc<RwLock<Connection>>` for libsql is unsafe under tokio. Per-op `connect()` is cheap.
+
+- Dense `Array2<f32>` for 50k×50k reservoir is infeasible (~10 GB). CSR with k=64 reduces to ~25 MB.
+- `HVec10240::permute()` with `bit_shift == 0` causes undefined behavior — must guard
+- `Arc<RwLock<Connection>>` for libsql is unsafe under tokio. Per-operation `connect()` is cheap and eliminates Send/Sync risks
 - Always use `f32::total_cmp()` for similarity sorting — `partial_cmp().unwrap()` panics on NaN
-- `inject_text()` does NOT store text — use `inject_text_with_metadata()` with `("_text", text)`
-- Min-max normalization amplifies noise — low HDC scores (~0.12) become 1.0
+- `Vec<Vec<(usize, f32)>>` incurs substantial allocator overhead; contiguous CSR buffers are faster
+- For large sparse reservoirs, memory locality can dominate runtime more than arithmetic throughput
+- **inject_text() does NOT store text content** — must use inject_text_with_metadata() with `("_text", text)` for retrieval
+- **probe_text() uses pure HDC similarity** — for short queries (1-2 tokens), BM25 hybrid with 90% keyword weight is better
+- **HDC returns low-similarity noise** — scores ~0.12 for unrelated documents. Must filter with threshold before hybrid merge
+- **Min-max normalization amplifies noise** — low HDC scores (0.12) become 1.0, competing with correct BM25 results
 
 ## What to Avoid
-- Dense matrices for reservoirs > ~2000 nodes
-- Sharing libsql `Connection` across async tasks via RwLock
-- `partial_cmp().unwrap()` on floats
-- `Vec<(String, f32)>` for associations — use `HashMap<String, f32>`
-- Multiple scripts with overlapping functionality — merge them
-- Archived GitHub repos as dependencies — fork or find active alternative
+
+- Do not use dense matrices for reservoirs > ~2000 nodes
+- Do not share a single libsql `Connection` across async tasks via RwLock
+- Do not use `partial_cmp().unwrap()` on floats
+- Do not assume `Vec<(String, f32)>` associations deduplicate — use `HashMap<String, f32>`
+- Do not use `cargo bench -- --baseline` (without `--bench benchmark`) — libtest benches interfere
+- Do not suppress deprecated libsql constructors long-term — migrate to `Builder`
+- Do not relax spectral-radius guardrails to chase speed
+- Do not pool connections for local SQLite (no benefit, adds overhead)
+- Do not make versioning mandatory (should be opt-in)
+- Do not create multiple scripts with overlapping functionality — merge related scripts (e.g., version checking into link checking)
+- Do not use archived GitHub repositories as dependencies — always find an active alternative or fork and maintain
+- Do not hardcode version numbers in test fixtures or examples — use current version or verify sync
+- **Do not use inject_text() when you need to retrieve the original text later** — use inject_text_with_metadata() instead

+# Skill Memory
+
+This repository uses two memory-oriented skills instead of one broad skill.
+
+## Skill Split
+
+- `skill-memory-internal`: daily dogfooding memory for agent development workflows.
+- `memory-lifecycle-verification`: portable verification for save/load/archive/delete across files and DB entries.
+
+## When to Use Which
+
+### `skill-memory-internal`
+
+Use during implementation, debugging, planning, and test loops to store and recall operational context.
+
+Path:
+
+- `.agents/skills/skill-memory-internal/SKILL.md`
+
+### `memory-lifecycle-verification`
+
+Use before release or when onboarding memory behavior into another codebase. This skill is the portability and correctness contract.
+
+Path:
+
+- `.agents/skills/memory-lifecycle-verification/SKILL.md`
+
+## Shared Configuration
+
+```yaml
+memory:
+  enabled: true
+  database: ".agents/csm-memory/skill-memory.db"
+  namespace_prefix: "skill"
+```
+
+## Internal Memory Quick Usage
+
+```bash
+export CSM_MEMORY_DB=".agents/csm-memory/skill-memory.db"
+
+# Save
+csm --database "$CSM_MEMORY_DB" inject \
+  "skill::impl::decision::$(date +%s)" \
+  --metadata '{"operation":"decision","result":"accepted"}'
+
+# Load
+csm --database "$CSM_MEMORY_DB" probe "decision accepted" -k 5 --output-format json
+
+# Associate
+csm --database "$CSM_MEMORY_DB" associate \
+  "skill::impl::decision::123" "skill::test::validation::123" -s 0.9
+```
+
+## Lifecycle Verification Minimum Contract
+
+Every verification run must prove all four operations:
+
+- `save`: data persisted and discoverable
+- `load`: export/import roundtrip preserves IDs and metadata
+- `archive`: archived state is recorded and auditable
+- `delete`: deleted/tombstoned entries are no longer active and leave no orphans
+
+Reference artifacts:
+
+- `.agents/skills/memory-lifecycle-verification/references/VALIDATION_CHECKLIST.md`
+- `.agents/skills/memory-lifecycle-verification/references/sql_checks.sql`
+
+## Why This Split
+
+- Keeps day-to-day memory use simple for internal agent work.
+- Makes lifecycle verification reusable in other repositories.
+- Ensures file + database behavior is testable with explicit evidence.

Subject: [PATCH 3/4] perf(hyperdim): optimize serialization and deduplicate
 agents

- Optimized HVec10240::to_bytes and from_bytes using memcpy on little-endian.
- Deduplicated 'benchmarking-perf' and 'testing-validation' skills in generate-agents.sh.
- Updated .opencode agents via scripts/generate-agents.sh.

Subject: [PATCH 4/4] perf(hyperdim): optimize serialization via single memcpy

Optimize HVec10240 serialization and deserialization by replacing
iterative word-by-word loops with a single memcpy on little-endian
platforms. This eliminates 80 bounds checks and word conversion
calls per operation.

hvec_to_bytes: 177ns -> 94ns (47% improvement)
hvec_from_bytes: 51ns -> 48ns (6% improvement)
