Wave 46 dim 19 dim F round 2 — cron MISSING axis close¶

Date: 2026-05-12 Branch: feat/jpcite_2026_05_12_wave46_dim19_F_round2 Worktree: /tmp/jpcite-w46-dim19-F2 Base: PR #118 head (feat/jpcite_2026_05_12_wave46_dim19_score_fix) Author: Wave 46 永遠ループ tick3 #6

Why round 2 (this PR) over the round 1 PR #118¶

Round 1 (PR #118) closed the REST api file MISSING axis of dim F by landing src/jpintel_mcp/api/fact_signature_v2.py (277 LOC) + tests/test_dimension_f_fact_signature_v2.py (7 tests). That moved dim F from 2.50/10 → ~4.50/10 and dim 19 average from 6.37 → ~6.47.

Per feedback_completion_gate_minimal the round 1 PR deliberately did NOT chase ETL / cron / MCP axes. Round 2 picks up exactly one more axis — the lowest-LOC / highest-leverage remaining gap — and lands that alone.

Selected axis: cron MISSING¶

Of the three remaining axes:

axis	LOC budget	status in repo	round 2 action
ETL MISSING	~200-400 LOC new ETL script	no ETL exists (the Ed25519 sign script is the ETL, but the audit treats sign as cron)	OUT OF SCOPE — round 3
cron MISSING	~110 LOC workflow YAML + 2 test asserts	Python `refresh_fact_signatures_weekly.py` exists but no `.github/workflows/*.yml` wires it	PICK
MCP grep miss	~80-150 LOC new MCP tool	no MCP wrapper	OUT OF SCOPE — round 4

Why cron over MCP: The Python cron script's docstring (line 35) explicitly references .github/workflows/refresh-fact-signatures-weekly.yml as the operational hook. The script is fully argparse-wired (--max-rows, --key-id, --dry-run, --verbose) and production-ready since Wave 43.2.5. Only the YAML wiring is missing. This is the single highest-leverage sub-criterion at the lowest LOC cost — it's literally a deploy-time config artifact, not new business logic.

Why not ETL or MCP this PR: Each requires non-trivial new business logic (ETL: source feed parser + UPSERT loop; MCP: tool schema + server wire + integration test). The completion-gate-minimal rule says one axis per PR. Take the cheap one first.

Sub-criterion checklist (dim F → 5 axes, cumulative across PR #118 + this PR)¶

axis	base (pre-#118)	post-#118	post-this-PR	delta this PR
migration forward-only: 2	PRESENT (262)	PRESENT	PRESENT	unchanged
REST api file	MISSING	PRESENT	PRESENT	unchanged (round 1)
ETL	MISSING	MISSING	MISSING	unchanged
cron	MISSING (Python upstream, no YAML)	MISSING	PRESENT	+1 axis
test(s)	1 (E shared)	2 (F-specific)	3 (F-specific +cron)	+1 test count
MCP grep	miss	miss	miss	unchanged

Estimated dim F score lift: ~4.50/10 → ~5.50-5.75/10 (+1 axis cron + 2 new tests). Dim 19 average projection: ~6.47 → ~6.55-6.58. Single sub-criterion, NOT a full 6.37 → 8.0 refactor.

Files changed¶

.github/workflows/refresh-fact-signatures-weekly.yml — 109 LOC new workflow (Sunday 02:00 UTC schedule + workflow_dispatch + failure issue create)
tests/test_dimension_f_fact_signature_v2.py — +59 LOC, 2 new tests: test_refresh_fact_signatures_workflow_exists and test_refresh_fact_signatures_workflow_no_llm_secret
docs/research/wave46/STATE_w46_dim19_F2_pr.md — this state doc

Total: ~170 LOC (workflow + test extension + state doc). Well under the ≤200 LOC source-code budget; mostly declarative YAML + assertions.

Workflow contract¶

name: refresh-fact-signatures-weekly

Trigger:
  schedule: 0 2 * * 0   (= Sunday 02:00 UTC, Monday 11:00 JST)
  workflow_dispatch:    max_rows / dry_run inputs

Step:
  flyctl ssh console -a autonomath-api -C \
    "/opt/venv/bin/python /app/scripts/cron/refresh_fact_signatures_weekly.py \
      [--max-rows N] [--dry-run]"

On failure:
  gh issue create --label cron-failure --label automation

Constraints honored¶

worktree /tmp/jpcite-w46-dim19-F2 (no main worktree touch)
no rm / mv (only Write + Edit)
no legacy brand strings on the wire (workflow names + script paths are internal infra; no jpcite rename impact)
no LLM API import (verified by test_refresh_fact_signatures_workflow_no_llm_secret)
1 sub-criterion fix (cron MISSING) — NOT a full 6.37 → 8.0 refactor
Builds on PR #118 head, NOT main, so the round 1 changes are preserved in the diff base

Lint + test verdict (2026-05-12)¶

ruff check tests/test_dimension_f_fact_signature_v2.py -> All checks passed!
pytest tests/test_dimension_f_fact_signature_v2.py -v -> 9 passed in 1.02s (7 -> 9, +2 new tests)
Regression: pytest tests/test_dimension_e_fact_verify.py -v -> 12 passed in 1.07s (no regression on dim E sibling)
YAML well-formedness: python3 -c "import yaml; yaml.safe_load(...)" -> OK
