What this changes

  • The docs now say what the code does: the off-task and should-proceed notices are trace-only, and action.offTask.warn, action.offTask.steer, action.shouldProceed.threshold, and action.shouldProceed.steer change only the reason text and the trace counts (docs/guards.md, docs/configuration.md).
  • scripts/steer-calibration.mjs draws a blind sample from a read-only copy of the hold log and scores the labels against candidate steer slices. scripts/steer-ask-probe.mjs measures a candidate question on the same labels.
  • should_ask joins the candidate questions in scripts/action-candidates.mjs: recorded only, never acted on.

No guard behavior changed and no steer ships. README.md still describes an off-task steer at 0.85; this change does not touch that file.

Measurement

Window: 27,387 judged calls recorded since 2026-09-25; 8,697 of them (32%) at or below 0.6 on should_proceed. 427 calls sampled in strata (150 mutating calls with scope unrelated, stratified by score; 50 plausible side step; 50 with no off-task reason; 150 at or below 0.6, stratified by score; 50 above) and labelled by hand without scores or strata in view. Off-task means "the call does not serve the user's request or a step it needs"; should-ask means "a careful engineer would ask the user before this call"; uncertain was allowed. Samples and labels stay outside the repository.

Gate to ship a steer: precision at or above 0.80 on at least 40 labelled calls in the slice, and at most 5 steers per 1,000 judged calls.

slice n labelled positives precision 95% interval recall per 1,000 judged gate
off-task: unrelated + mutating, P >= 0.85 42 (+6 uncertain) 0 0.00 [0.00, 0.08] 0.00 1.75 fails precision

should-ask: P <= 0.10 76 (+1) 2 0.03 [0.01, 0.09] 1.00 6.94 fails precision, rate
should-ask: P <= 0.20 138 (+1) 2 0.01 [0.00, 0.05] 1.00 31.18 fails precision, rate
should-ask: P <= 0.40 225 (+1) 2 0.01 [0.00, 0.03] 1.00 127.69 fails precision, rate

No slice passes. The labels hold no off-task call in 427 (95% upper bound below 1%) and two should-ask calls: merging two pull requests that no instruction named, and reading a third-party API key from a live deployment for a side experiment. Both steers therefore stay trace-only, as the code already has them.

Blocked measurement

The proposed rewording (should_ask) is meant to be measured on these same labels by scripts/steer-ask-probe.mjs, one request per call, next to the shipped question. The run cannot complete: the TypeSafe account answers HTTP 402 (no balance). Smallest unblocking action: fund the account, or export a funded TYPESAFE_API_KEY, then run the probe with --yes and score it with --score. Until those numbers exist the question stays extra-only.

Checks

  • npm run check on this branch: typecheck clean, 1263 of 1263 tests pass, build clean.
  • npm run check on the base commit: typecheck clean, 1263 of 1263 tests pass, build clean.

Closing: the content of this pull request (its docs, README rows, and scripts, with the labeller corrected to one language model) is included in #162, without the version bump.

#162)

Makes the README and docs true for 1.0 and describes what 1.0 ships.
Draft: no version bump, and nothing under `src/` changes (`git diff
origin/main...HEAD -- src` is empty). The A/B results and the 1.0.0 bump
come later.

## What changed

- **Steer calibration (#151) brought in**: its docs, README rows,
`scripts/steer-calibration.mjs`, `scripts/steer-ask-probe.mjs` and
`should_ask`. Not its version bump or CHANGELOG version heading.
Corrected: the labels were made by one language model, not "by hand",
and a script comment no longer uses an internal term.
- **"By hand" claims removed.** 140 intent-mismatch labels (README,
guards.md, CHANGELOG): the record (#139) does not say who labelled them,
so the text now says that. The 14-call sample in the old field report:
same.
- **`scripts/field-usage.mjs`**: the steer classifier knows eight more
message kinds. "Other" steers, 2026-09-16 to 2026-10-01: 239 of 1,834
(13.0%) → 10 (0.5%). 2026-09-25 to 2026-10-01: 152 of 473 (32.1%) → 5
(1.1%). The JSON carries rule counts, not rule names.
- **New field report** `eval/reports/2026-10-01-field-usage/` (aggregate
counts only); hero image and Receipts refreshed from it
(`scripts/render-hero.mjs`).
- **README**: 1.0 features, a "What it costs" section, the
Jev/offline-floor sentence fixed, off-task and should-proceed rows,
Learning from holds matches #149.
- **docs/guards.md**: Action guard step 3 describes the acting request,
trace-only questions and ask gate as shipped. Calibration now records
the ask gate and lean request, and three negative results:
working-memory gate (checked against #152), relevance compaction hybrid
(#150), stale-result stubs (#158).
- **Doc mismatches fixed**: `docs/extension-authors.md` (`verdict.level`
includes `"deny"`); `docs/data-handling.md` (conscience local ranking
and what sends nothing; allowed rows keep judge data, held rows keep the
summary); `docs/commands.md` (`/warden status` lifetime hold counts);
`docs/configuration.md` (off-task and should-proceed rows). The other
claims in those four docs matched `src/`.

## Still to do before ready for review

- `npm run check` result with its test count (not run on this commit
yet).


#151 content is included here; it will be closed with a pointer.



## Second pass (docs checked against src)

- `docs/configuration.md` vs `src/config.ts`: the defaults JSON and the
widget templates match `defaultConfig()` key for key. Fixed:
`compaction.maxRequests` default 12 (doc said 20); the project-file
table now lists `action.ask.enabled` and
`rulesAtTurnStart.enabled`/`.threshold` as stricter-only; user-only keys
named (`typesafeBackend`, `context.filter.enabled`,
`security.maskOutput`, `widget`, `steers`, `learning`, `conscience`,
`steerVisible`, `notices`, `steerBudget`, rule lists, `action.floor`);
added `stuck.diffLimit`, `stuck.tailLimit`, `context.compactAppendix`,
`PI_WARDEN_DB`, `PI_WARDEN_STEER_STATS`, `PI_WARDEN_INDEX_DIR`; bounds
for `runaway.repeats`, `waste.every`, `visibleMismatch`; index path
typo; a table that lost its header.
- `docs/guards.md` vs `src/`: caps and limits checked
(250/750/1200/1500/2000/3000/6000 characters, 256/24 runaway, spine,
steer kinds). Fixed: adaptive-steer kind list now matches `STEER_KINDS`
and `NEVER_MUTED`. Calibration sections are measurements and were not
re-run.
- `npm run check`: typecheck, build, and 1412 tests pass (1412 pass, 0
fail). `main` was already merged.


- Added `docs/upgrading.md` (0.74.1 to 1.0) with a README pointer. Each
point was checked against `src/` and the 0.74.1 tag; the 1.0 config
warning for the two removed keys is not in this PR, so the page says
only that they are ignored. No version bump.



The last commit bumps the version to 1.0.0, after merging the config
warnings for the two removed settings; the upgrade guide names that
warning.
