From 3011166b3cc456a71713347813ae69a5b6902d8f Mon Sep 17 00:00:00 2001 From: Pavel Fadeev Date: Fri, 18 Sep 2026 00:35:33 +0200 Subject: [PATCH 1/2] feat: gate, packs, records, and offline development MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the decision layer the CLI was missing: questions are judged by the model, policy is applied offline to a saved answer. - `jev gate --input --pack |--policy ` evaluates rules offline and exits 0 accept / 2 review / 3 deny / 4 abstain. Fail-closed: a missing or wrong-typed answer abstains, and a choice label outside `accept` never accepts, however confident the model is. - `packs/` ships versioned question sets with embedded policies: verify (claim vs. evidence), screen (injection, harmful content, severity; plus substance and relevance for the caller), route (handler class + complexity). `jev packs` lists them with a content hash; `ask --pack ` uses one. - `--record ` writes a decision record: model resolved, latency, pack hash, and hashes of the state and questions — the state itself is never stored. `jev replay --record ` re-emits stored answers without a call. - `jev doctor [--live]` checks engine, key presence (never the value), base URL, model, and pack validity; `--live` also authenticates, lists models, and times a probe. - `--version` now reads package.json at runtime instead of a hardcoded string. - Fix: SIGINT/SIGTERM cancellation was dropped — the signal travelled in client options, which ignore it, instead of request options. - Fix: `batch` JSON rows bypassed cost enrichment, so they lacked the `cost` block every other JSON response carries. The publish workflow stages instead of publishing: trusted publishers created after 2026-09-03 are staging-only, which is why run 35279646306 received "OIDC permission denied" after signing provenance. It now requires the release tag to match the committed version (rather than rewriting it), installs a staging-capable npm CLI (>= 11.15.0), and runs `npm stage publish` for a maintainer to approve with 2FA. Offline development: `tools/stub-server.mjs` answers deterministically and non-committally so a pipeline can be wired without a key, and `tools/evaluate.mjs` scores a policy against labeled records (accuracy, outcome mix, acceptance rate per probability bucket) without touching the inference path. --- .github/workflows/npm-publish.yml | 55 +++-- CLAUDE.md | 26 ++- README.md | 165 +++++++++++++- examples/README.md | 100 +++++++++ examples/policies/verify-strict.json | 14 ++ examples/screen/untrusted-page.txt | 11 + examples/verify/c1.json | 4 + examples/verify/c2.json | 4 + examples/verify/c3.json | 4 + examples/verify/c4.json | 4 + examples/verify/c5.json | 4 + examples/verify/c6.json | 4 + examples/verify/labels.jsonl | 6 + package-lock.json | 6 +- package.json | 6 +- packs/route.json | 51 +++++ packs/screen.json | 73 ++++++ packs/verify.json | 34 +++ src/cli.ts | 49 +++- src/cli/formatters.ts | 129 ++++++++++- src/cli/help.ts | 100 ++++++++- src/cli/parseArgs.ts | 15 ++ src/cli/policy.ts | 323 +++++++++++++++++++++++++++ src/cli/records.ts | 87 ++++++++ src/commands/doctor.ts | 96 ++++++++ src/commands/gate.ts | 70 ++++++ src/commands/ops.ts | 43 +++- src/commands/packs.ts | 100 +++++++++ src/commands/replay.ts | 18 ++ src/commands/requests.ts | 119 ++++++++-- src/index.ts | 10 + src/tests/contract.test.ts | 168 +++++++++++++- src/tests/gate.test.ts | 284 +++++++++++++++++++++++ src/utils/hash.ts | 20 ++ src/utils/package.ts | 34 +++ tools/evaluate.mjs | 186 +++++++++++++++ tools/stub-server.mjs | 97 ++++++++ 37 files changed, 2443 insertions(+), 76 deletions(-) create mode 100644 examples/README.md create mode 100644 examples/policies/verify-strict.json create mode 100644 examples/screen/untrusted-page.txt create mode 100644 examples/verify/c1.json create mode 100644 examples/verify/c2.json create mode 100644 examples/verify/c3.json create mode 100644 examples/verify/c4.json create mode 100644 examples/verify/c5.json create mode 100644 examples/verify/c6.json create mode 100644 examples/verify/labels.jsonl create mode 100644 packs/route.json create mode 100644 packs/screen.json create mode 100644 packs/verify.json create mode 100644 src/cli/policy.ts create mode 100644 src/cli/records.ts create mode 100644 src/commands/doctor.ts create mode 100644 src/commands/gate.ts create mode 100644 src/commands/packs.ts create mode 100644 src/commands/replay.ts create mode 100644 src/tests/gate.test.ts create mode 100644 src/utils/hash.ts create mode 100644 src/utils/package.ts create mode 100755 tools/evaluate.mjs create mode 100755 tools/stub-server.mjs diff --git a/.github/workflows/npm-publish.yml b/.github/workflows/npm-publish.yml index 87d4c0a..d25bba4 100644 --- a/.github/workflows/npm-publish.yml +++ b/.github/workflows/npm-publish.yml @@ -1,5 +1,9 @@ name: Publish to npm +# Staged publishing: the workflow submits the tarball, a maintainer approves it +# with 2FA.

Each one was a path where a malformed or ambiguous input could still reach `accept`: - Choice rules no longer fall back to `confidence` when the probability map is missing or lacks the chosen label. Confidence describes the answer as a whole, not that label, so substituting it let `{"supports": 2}` accept. The map must now be numbers in [0, 1] summing to 1 (tolerance 0.05); anything else abstains. - Score rules check the scale: the score must fall inside the rule's `range`, or the level indices the answer reports in legend/probabilities. `severity: -100` sailed under `accept_at: 0.5` before. - Record envelopes are validated, never reinterpreted: a `record_version` this CLI does not write, or a non-object `response`, exits 1 instead of falling back to a conflicting top-level `answers`. - Gating a record against its pack now checks identity. Changed questions exit 1 (stored answers no longer mean what the rules assume); changed thresholds only warn and apply, because the answers still mean the same thing. The pack hash and that comparison print in table output too, not just JSON. - State hashes are type-tagged and versioned, so a text state no longer collides with the JSON state that parses to the same bytes. - `--record` creates missing parent directories before the request, so a bad path cannot fail after an answer was paid for. - Lint rejects an inverted choice band (`review_at > accept_at`), a repeated accepted label, and a malformed `range`; evaluation counts each accepted label once regardless. - `tools/evaluate.mjs` buckets by the probability the policy treats as permission for the primary rule, not by the chosen label's probability. The old metric mixed confident `supports` with confident `contradicts` and could call good separation flat. Score rules are excluded from the curve; they are not probabilities. - The stub never claims the requested model: `model_resolved` is `stub:`, so a stub record is identifiable as one. A contract test asserts, through the real transport, that all three bundled policies deny stub answers — the claim the docs make. - Docs: narrowed the record-hash claim to an input commitment, documented the fail-closed rules and pack-drift behavior, and fixed examples that did not run (record path, route pipeline, stub accuracy). --- .github/workflows/npm-publish.yml | 5 +- CLAUDE.md | 7 +- README.md | 24 +++++-- examples/README.md | 24 ++++--- src/cli/formatters.ts | 12 ++++ src/cli/help.ts | 13 ++++ src/cli/policy.ts | 103 ++++++++++++++++++++++++++---- src/cli/records.ts | 63 ++++++++++++------ src/commands/gate.ts | 42 +++++++++--- src/commands/replay.ts | 11 ++-- src/commands/requests.ts | 7 ++ src/tests/contract.test.ts | 84 +++++++++++++++++++++++- src/tests/gate.test.ts | 76 +++++++++++++++++++--- tools/evaluate.mjs | 54 ++++++++++++---- tools/stub-server.mjs | 5 +- 15 files changed, 445 insertions(+), 85 deletions(-) diff --git a/.github/workflows/npm-publish.yml b/.github/workflows/npm-publish.yml index d25bba4..30e0036 100644 --- a/.github/workflows/npm-publish.yml +++ b/.github/workflows/npm-publish.yml @@ -26,10 +26,11 @@ jobs: package-manager-cache: false # Staged publishing needs npm >= 11.15.0; the version bundled with Node may - # be older (11.6.x rejects "npm stage" as an unknown command). + # be older (11.6.x rejects "npm stage" as an unknown command).
