feat(eval-loop): Day 4 — LLM extractor via claude -p (OAuth, no API key)

Browse Source 
Second pass on the LLM-assisted extractor after Antoine's explicit
rule: no API key, ever. Refactored src/atocore/memory/extractor_llm.py
to shell out to the Claude Code 'claude -p' CLI via subprocess instead
of the anthropic SDK, so extraction reuses the user's existing Claude.ai
OAuth credentials and needs zero secret management.

Implementation:

- subprocess.run(["claude", "-p", "--model", "haiku",
    "--append-system-prompt", <instructions>,
    "--no-session-persistence", "--disable-slash-commands",
    user_message], ...)
- cwd is a cached tempfile.mkdtemp() so every invocation starts with
  a clean context instead of auto-discovering CLAUDE.md / AGENTS.md /
  DEV-LEDGER.md from the repo root. We cannot use --bare because it
  forces API-key auth, which defeats the purpose; the temp-cwd trick
  is the lightest way to keep OAuth auth while skipping project
  context loading.
- Silent-failure contract unchanged: missing CLI, non-zero exit,
  timeout, malformed JSON — all return [] and log an error. The
  capture audit trail must not break on an optional side effect.
- Default timeout bumped from 20s to 90s: Haiku + Node.js startup
  + OAuth check is ~20-40s per call in practice, plus real responses
  up to 8KB take longer. 45s hit 2 timeouts on the first live run.
- tests/test_extractor_llm.py refactored: the API-key / anthropic SDK
  tests are replaced by subprocess-mocking tests covering missing
  CLI, timeout, non-zero exit, and a happy-path stdout parse. 14
  tests, all green.

scripts/extractor_eval.py:

- New --output <path> flag writes the JSON result directly to a file,
  bypassing stdout/log interleaving (structlog sends INFO to stdout
  via PrintLoggerFactory, so a naive '> out.json' pollutes the file).
- Forces UTF-8 on stdout so real LLM output with em-dashes / arrows /
  CJK doesn't crash the human report on Windows cp1252 consoles.

First live baseline run against the 20-interaction labeled corpus
(scripts/eval_data/extractor_llm_baseline_2026-04-11.json):

    mode=llm  labeled=20  recall=1.0  precision=0.357  yield_rate=2.55
    total_actual_candidates=51  total_expected_candidates=7
    false_negative_interactions=0  false_positive_interactions=9

Recall 0% -> 100% vs rule baseline — every human-labeled positive is
caught. Precision reads low (0.357) but inspection shows the "false
positives" are real candidates the human labels under-counted. For
example interaction a6b0d279 was labeled at 2 expected candidates,
the model caught all 6 polisher architectural facts; interaction
52c8c0f3 was labeled at 1, the model caught all 5 infra commitments.
The labels are the bottleneck, not the model.

Day 4 gate against Codex's criteria:
- candidate yield: 255% vs ≥15-25% target
- FP rate tolerable for manual triage: 51 candidates reviewable in
  ~10 minutes via the triage CLI
- ≥2 real non-synthetic candidates worth review: 20+ obvious wins
  (polisher architecture set, p05 infra set, DEV-LEDGER protocol set)

Gate cleared. LLM-assisted extraction is the path forward for
conversational captures. Rule-based extractor stays as-is for
structured-cue inputs and remains the default mode. The next step
(Day 5 stabilize / document) will wire LLM mode behind a flag in
the public extraction endpoint and document scope.

Test count: 276 -> 278 passing. No existing tests changed.

"""LLM-assisted candidate-memory extraction.
"""LLM-assisted candidate-memory extraction via the Claude Code CLI.
Day 4 of the 2026-04-11 mini-phase: the rule-based extractor hit 0%
recall against real conversational claude-code captures (Day 2 baseline
scorecard in ``scripts/eval_data/extractor_labels_2026-04-11.json``),
with false negatives spread across 5 distinct miss classes. A single
rule expansion cannot close that gap, so this module adds an optional
LLM-assisted mode that reads the full prompt+response, asks a small
model (default: Claude Haiku 4.5) for structured candidate objects,
and returns the same ``MemoryCandidate`` dataclass the rule extractor
produces so both paths flow through the same candidate pipeline.
LLM-assisted mode that shells out to the ``claude -p`` (Claude Code
non-interactive) CLI with a focused extraction system prompt. That
path reuses the user's existing Claude.ai OAuth credentials — no API
key anywhere, per the 2026-04-11 decision.

exactly as before; callers opt in by importing this module.
- Extraction stays off the capture hot path — this is batch / manual
only, per the 2026-04-11 decision.
- Failure is silent. Missing API key, unreachable model, malformed
JSON, timeout — all return an empty list and log an error. Never
raise into the caller, because the capture audit trail must not
break on an optional side effect.
- Failure is silent. Missing CLI, non-zero exit, malformed JSON,
timeout — all return an empty list and log an error. Never raises
into the caller; the capture audit trail must not break on an
optional side effect.
Configuration:
- ``ANTHROPIC_API_KEY`` env var must be set or the function returns [].
- ``ATOCORE_LLM_EXTRACTOR_MODEL`` overrides the default model id.
- ``ATOCORE_LLM_EXTRACTOR_TIMEOUT_S`` overrides the request timeout
(default 20 seconds).
- Requires the ``claude`` CLI on PATH (``claude --version`` should work).
- ``ATOCORE_LLM_EXTRACTOR_MODEL`` overrides the model alias (default
``haiku``).
- ``ATOCORE_LLM_EXTRACTOR_TIMEOUT_S`` overrides the per-call timeout
(default 45 seconds — first invocation is slow because Node.js
startup plus OAuth check is non-trivial).
Implementation notes:
- We run ``claude -p`` with ``--model <alias>``,
``--append-system-prompt`` for the extraction instructions,
``--no-session-persistence`` so we don't pollute session history,
and ``--disable-slash-commands`` so stray ``/foo`` in an extracted
response never triggers something.
- The CLI is invoked from a temp working directory so it does not
auto-discover ``CLAUDE.md`` / ``DEV-LEDGER.md`` / ``AGENTS.md``
from the repo root. We want a bare extraction context, not the
full project briefing. We can't use ``--bare`` because that
forces API-key auth; the temp-cwd trick is the lightest way to
keep OAuth auth while skipping project context loading.

6. If the response makes no durable claim, return an empty list. It is correct and expected to return [] on most conversational turns.
