Session 1 of the four-session plan. Empirically exercises the Phase 9
loop (capture -> reinforce -> extract) for the first time and lands
three small hygiene fixes.
Validation script + report
--------------------------
scripts/phase9_first_real_use.py — reproducible script that:
- sets up an isolated SQLite + Chroma store under
data/validation/phase9-first-use (gitignored)
- seeds 3 active memories
- runs 8 sample interactions through capture + reinforce + extract
- prints what each step produced and reinforcement state at the end
- supports --json output for downstream tooling
docs/phase9-first-real-use.md — narrative report of the run with:
- extraction results table (8/8 expectations met exactly)
- the empirical finding that REINFORCEMENT MATCHED ZERO seeds
despite sample 5 clearly echoing the rebase preference memory
- root cause analysis: the substring matcher is too brittle for
natural paraphrases (e.g. "prefers" vs "I prefer", "history"
vs "the history")
- recommended fix: replace substring matcher with a token-overlap
matcher (>=70% of memory tokens present in response, with
light stemming and a small stop list)
- explicit note that the fix is queued as a follow-up commit, not
bundled into the report — keeps the audit trail clean
Key extraction results from the run:
- all 7 heading/sentence rules fired correctly
- 0 false positives on the prose-only sample (the most important
sanity check)
- long content preserved without truncation
- dedup correctly kept three distinct cues from one interaction
- project scoping flowed cleanly through the pipeline
Hygiene 1: FastAPI lifespan migration (src/atocore/main.py)
- Replaced @app.on_event("startup") with the modern @asynccontextmanager
lifespan handler
- Same setup work (setup_logging, ensure_runtime_dirs, init_db,
init_project_state_schema, startup_ready log)
- Removes the two on_event deprecation warnings from every test run
- Test suite now shows 1 warning instead of 3
Hygiene 2: EXTRACTOR_VERSION constant (src/atocore/memory/extractor.py)
- Added EXTRACTOR_VERSION = "0.1.0" with a versioned change log comment
- MemoryCandidate dataclass carries extractor_version on every candidate
- POST /interactions/{id}/extract response now includes extractor_version
on both the top level (current run) and on each candidate
- Implements the versioning requirement called out in
docs/architecture/promotion-rules.md so old candidates can be
identified and re-evaluated when the rule set evolves
Hygiene 3: ~/.git-credentials cleanup (out-of-tree, not committed)
- Removed the dead OAUTH_USER:<jwt> line for dalidou:3000 that was
being silently rewritten by the system credential manager on every
push attempt
- Configured credential.http://dalidou:3000.helper with the empty-string
sentinel pattern so the URL-specific helper chain is exactly
["", store] instead of inheriting the system-level "manager" helper
that ships with Git for Windows
- Same fix for the 100.80.199.40 (Tailscale) entry
- Verified end to end: a fresh push using only the cleaned credentials
file (no embedded URL) authenticates as Antoine and lands cleanly
Full suite: 160 passing (no change from previous), 1 warning
(was 3) thanks to the lifespan migration.
