Parfii-bot eedffd1cd2 feat(kei-memory): functional schema fix + 4-wave architecture refactor
Wave A — Functional ingest fix (root cause of empty Sleep reports):
- Rewrote TraceLine struct to match real Claude Code trace JSONL:
  type (was kind), timestamp ISO8601 (was epoch ts), message Object,
  cwd / gitBranch / parentUuid / uuid / subtype / toolUseID / toolUseResult
- New src/extract.rs: extract_tool_uses + extract_tool_result walks
  message.content[] for nested tool_use / tool_result blocks
- New src/classifier.rs: explicit table classifier (tool_error, user_correction,
  retry_loop, permission_denied, tool_use:<name>, ...) replaces shallow heuristic
- New src/error.rs: KeiMemoryError enum (IO/Parse/Db) replaces semantic
  mismatch where IO error was wrapped as rusqlite::InvalidParameterName
- New src/trace_line.rs: TraceLine + helpers (cube extraction)
- Schema migration v3: events.cwd column + 3 hot-query indices
  (events.tool, events.file_path, events.ts) + UNIQUE on patterns
- New tests/ingest_real_trace.rs: synth-fixture asserts tool/file/cwd/class extraction

Wave B — Lib crate split:
- Cargo.toml: [lib] target added alongside existing [[bin]]
- src/lib.rs: pub re-export of all 18 modules
- src/main.rs: 11 mod declarations replaced by single use kei_memory::{…}
- tests/integration.rs: #[path] hack replaced by use kei_memory::{…}

Wave C — TF-IDF dedup + single-JOIN + filter_map fix:
- Schema migration v2: tokens.idf_dirty column + flag-based dedup
- index_document no longer triggers per-call recompute_idf rebuild
- top_similar uses single JOIN via vectors_for_overlapping_sessions helper
  (was N round-trips, one session_vector per candidate)
- All filter_map(|r| r.ok()) row-error swallowing replaced with ? propagation
- New tests/tfidf_idf_dedup.rs: 4 tests covering dedup behaviour, IDF emptiness,
  JOIN-pruning, empty-query safety

Wave D — Commands split + nits:
- New src/dump.rs (43 LOC) + src/stats.rs (33 LOC):
  CLI renderers extracted from commands.rs (was inline SQL + format)
- src/commands.rs: thin wrappers, -42 LOC
- src/injection_guard.rs: inline tests removed (-26 LOC), file under 200 LOC threshold
- tests/injection_guard_unit.rs (new): 4 tests in proper integration crate
- src/patterns.rs: INSERT replaced with INSERT...ON CONFLICT...DO UPDATE
  (idempotent re-ingest, uses Wave A's UNIQUE index)
- src/analyze.rs + src/coaccess.rs: filter_map row-error fixes
- src/coaccess.rs: misleading PK comment rewritten

Verify-before-commit (RULE 0.13 §"Verify-before-commit"):
- cargo check --all-targets: PASS (1 unrelated dead-code warning)
- cargo test: 42 passed, 0 failed across 9 test binaries
- STATUS-TRUTH markers aggregated at .claude/agents/_merge/kei-memory-2026-05-01/

Architect-spotted ARCH-MAJOR + ARCH-MINOR + ARCH-NIT findings addressed:
- ARCH-MAJOR Cargo.toml binary-only (Wave B)
- ARCH-MAJOR schema missing indices (Wave A v3)
- ARCH-MAJOR ingest_jsonl choke point (Wave A — extract.rs + classifier.rs)
- ARCH-MAJOR idf O(N·V) per-call rebuild (Wave C)
- ARCH-MINOR patterns no UPSERT (Wave D)
- ARCH-MINOR commands.rs houses dump+stats (Wave D)
- ARCH-MINOR classifier silent contract (Wave A)
- ARCH-MINOR IO error wrapped as rusqlite (Wave A)
- ARCH-MINOR injection_guard inline tests (Wave D)
- ARCH-MINOR tfidf top_similar N round-trips (Wave C)
- ARCH-NIT 3× filter_map(|r| r.ok()) sites (Wave C + D)
- ARCH-NIT coaccess misleading comment (Wave D)

=== STATUS-TRUTH MARKER ===
shipped: functional
stubs: 0
cargo-check: PASS
cargo-test: PASS (42 tests, 0 failures)
behaviour-verified: yes
follow-up-required:
  - tests/ingest_guard_tests.rs + tests/guard_test_corpus.rs still on #[path] hack (Wave B follow-up note, ~5 LOC)
  - dead_code warning Severity::Warn unused (pre-existing, not blocking)

//! Event dump renderer — print events for a session as markdown.
//!
//! Constructor Pattern: extracted from commands.rs (was `dump_events`).
//! Pure formatter: takes a Connection + session_id, returns a String.
//! The CLI wrapper in commands.rs prints it; library callers can capture.
use rusqlite::{params, Connection, Result};
/// Render a session's events as a markdown bullet list.
///
/// Output starts with a `# session <id>` header followed by one bullet
/// per event ordered by timestamp ASC. Errors propagate from the
/// underlying SQLite query / row decoding.
