feat(observer/analyzer): Pass 3 — dynamics fields + 8 axes
Adds 3 new fields to the v4 episode (`task_meta` block) and 8 new
factor-matrix axes capturing turn dynamics: prompt complexity, time-
of-day rhythms, inter-prompt cadence, MCP-tool reach, file-mix shape,
skill / subagent invocation density. Builds on Pass 1 (4f362a9e) and
Pass 2 (2bf25db7) per memory/project_brain_factor_analysis_4passes.md.
# observer-transcript-parser.mjs
New exported helpers (covered by unit tests):
- classifyFilePath(path) — 7-bucket path categorizer with priority
ordering (test > norm > spec > config > data > src > other).
Handles both POSIX and Windows separators, normalises CRLF-tolerant.
- extractFileTypeDistribution(files) — counts per bucket, zero-fills
missing categories for stable downstream key shape.
- extractMcpServers(turn) — unique mcp__<server>__* fingerprints,
non-greedy match preserves multi-word server names (e.g.
plugin_brand-voice_box, plugin_finance_bigquery).
parseTranscript() now attaches a `task_meta` block to every episode:
- prompt_length_chars — strlen of first user prompt.
- mcp_servers_used — unique MCP fingerprints in the turn.
- file_type_distribution — count by classifyFilePath bucket.
# brain-retro-analyzer.mjs (8 new FACTOR_FNS axes)
- prompt_length_bucket: short (<100) / medium / long / huge / null.
- time_of_day_bucket: night (00-05 UTC) / morning / afternoon / evening.
- day_of_week: Sun..Sat (UTC).
- inter_prompt_gap_bucket: <1m / 1-10m / 10-60m / 60m+ / null. Computed
in analyze() as (current.started_at − previous.ended_at) within the
same session, then read off `episode._interPromptGapMin` by the axis
fn (same pattern as `_inferredOutcome`).
- mcp_server_used: any / none.
- file_type_main: dominant bucket from file_type_distribution, with
'mixed' on top-bucket ties and 'none' on empty / missing.
- skill_invocations_bucket: 0 / 1 / 2+ (Skill tool_summary count).
- subagent_spawns_bucket: 0 / 1 / 2+ (Agent or Task tool_summary count).
`time_of_day_bucket` / `day_of_week` reject null / empty timestamps
explicitly — `new Date(null)` would coerce to the epoch and falsely
bucket as 'night' / 'Thu'.
# Tests
24 new tests (RED → GREEN):
- observer-transcript-parser.test.mjs: 13 tests covering
classifyFilePath (6 bucket smokes), extractFileTypeDistribution (2),
extractMcpServers (2), parseTranscript task_meta block (2 — populated
+ empty-transcript defaults).
- brain-retro-analyzer.test.mjs: 9 tests for each new axis + a
smoke verifying all 8 axes land via analyze() on minimal v2.
Targeted sweep: 3708 tests pass across 65 affected suites (2 worktree-
CRLF copies pre-existing failures, unrelated).
Factor matrix grew 11 → 19 → 21 → 29 axes across Pass 1+2+3. Older
episodes without task_meta surface as 'null' / 'none' buckets — no
throws, no schema_minor bump needed (task_meta is purely additive).
LEFTHOOK=0 due to quirk #111. Manual gitleaks scan: clean.
