* feat: implement act apply-model and report baseline tripwire (#607)
* fix(act): scope model-default tripwire to the applied project
Review fixes for #616:
- modelDefaultRow and the under-20-edit-turns gate now aggregate only the
target project's sessions (derived from changes[0].path, separators
normalized before dirname), matching the per-project baseline captured at
apply time instead of comparing against all projects.
- baseline.candidateModel labels the candidate explicitly, with a
backward-compatible fallback to metrics key order for existing journals.
- measured model-default rows render a correlation marker instead of a
formatTokens(0) token claim.
- zero-matching-projects now reports an honest project-not-found note; clean
rows route through confidenceFor like every other kind.
- tests: tripwire fires on a same-project regression that global aggregation
would mask (fails on pre-fix code), clean and not-measurable cases,
Windows-separator journal paths with an excluded masking project.
Bug-hunt follow-ups on the realized-savings report:
- Scale the displayed estimate to the measured window so the Estimated and
Realized columns are comparable: mcp/archive use the per-session baseline
times the post-window session count, read-edit uses deficitThen times the
same edits denominator as realized (so realized never exceeds it). The
at-apply estimate stays in --json as estimatedAtApply next to
estimatedForWindow; the footer states the scaling and that mcp/archive
realized figures are derived from session counts, not independently
measured.
- Never crash on a corrupt journal: records without a string status or a
parseable string `at` are skipped and surfaced ("N malformed records
skipped"); the optimize header computation is additionally wrapped so any
error just drops the header.
- Zero post-window sessions now reads "not measurable: no sessions in the
window yet" instead of measured-zero.
- The optimize header sums only normal-confidence measured rows (under-claim);
low-confidence rows stay visible in act report only.
- Tests: floor discipline on non-integer mcp and read-edit products (a ceil
mutation fails), the project-scope keeper subtraction, the archive
estimate==realized tautology, malformed-journal robustness, and the
low-confidence header exclusion.
Capture a trailing-14-day before-baseline when a fix is applied and
re-measure it against the post-apply window so optimize can show realized
numbers next to estimates.
- ActionBaseline (windowDays, capturedAt, estimatedTokens, sessions, metrics)
persisted by runAction; captured in the optimize --apply flow and at guard
install time.
- codeburn act report [--json]: applied, not-undone actions older than 3 days,
re-running the detectors over apply-date-to-now (capped 30 days). Per-kind
realized deltas: MCP/archive tokens-per-session times saved sessions with
reverted-by-user detection; read-edit deficit reduction; guard yield split
labeled correlation. Bash cap is marked not measurable (result sizes are not
retained). Low confidence under 20 post-window sessions or past a 2x volume
shift. Realized numbers rounded down, estimate kept visible.
- optimize gains one header line only when a measured action exists, and
appends "(previously applied <date>, re-flagged)" to re-triggered findings.
No change for users with no applied actions.
Reuses scanAndDetect helpers over a date-bounded range; exports the token
constants and read/edit tool sets rather than duplicating the math.
