The runtime loads public policy and a Windows CurrentUser DPAPI credential, sanitizes bounded state and questions, and checks the session cache. For a provider attempt it reserves the maximum documented request cost in a shared SQLite transaction, sends only to the official HTTPS endpoint, and validates the entire typed response. Known input usage settles the reservation; absent or invalid usage retains it. A retry reserves again.

Evidence assessments never certify completion. Jev output cannot change canonical benchmark grades, evidence artifacts or memory by itself. Offline and unavailable states carry no synthetic decision. Consumers resume their ordinary model and executable verification workflow. -1. **Non-Generative Decision Architecture**: Jev generates **zero prose tokens**. Output tokens are unmetered ($0) because it returns typed numerical probability vectors over predefined questions rather than autoregressive sequences. -2. **Elimination of JSON & Syntax Retries**: Because outputs are deterministic scalar/vector primitives, there are no malformed JSON blobs, no markdown code fence parsing errors, and zero token-wasting retry loops. -3. **Single Forward-Pass Multi-Question Parallelism**: Jev evaluates an arbitrary set of questions against a shared state in a **single parallel forward pass**. Evaluating 1 question vs 8 questions costs virtually identical latency (70–300 ms). -4. **Calibrated Probabilities via RLCD**: Unlike standard LLM logit outputs that drift or over-confidently hallucinate, Jev is trained via *Reinforcement Learning for Calibrated Decisions* (RLCD). A reported probability $p = 0.92$ empirically reflects 92% ground-truth accuracy. -5. **Disruptive Unit Economics**: At **$0.042 per million input tokens** and **$0 output tokens**, Jev is ~100x–400x cheaper than frontier LLM calls, turning high-frequency guardrail and filtering checks from cost liabilities into near-zero-cost operations. +## Evidence selection ---- +Saved UTF-8 evidence can be read through approved workspace roots. Resolve and check paths, reject sensitive names, enforce byte limits, sanitize excerpts, and retain original SHA-256 and source line locations. Large windows that exceed provider bounds remain available locally rather than being truncated into misleading evidence. All bounded windows are assessed together against complete shared state. -## 2. Jev Primitives & Core Protocol +Pruning is off by default. Even when explicitly enabled after calibration, uncertain assessments retain content. Failure details, test summaries, exit codes, diff boundaries and original artifacts remain protected. Actual token savings require primary-model telemetry; byte counts are not tokens. A tool cannot remove text already consumed by a model. -Jev operates over three typed decision primitives: +## Accounting and transport -| Primitive | Return Type | Description | Primary Use Case in Harnesses | -|---|---|---|---| -| **Noul** | `float` (0.0 to 1.0) | Calibrated Bayesian probability that a proposition is true ($P(\text{True})$). | Tool safety check, loop completion verification, contradiction presence. | -| **Choice** | `Dict[str, float]` | Probability distribution over a closed set of categorical labels. | Tool routing, action classification (`safe_read`, `file_edit`, `destructive`, `network_leak`). | -| **Score** | `int` / `float` (ordinal scale) | Position on a defined rubric scale (e.g. 0 to 4). | Context chunk relevance ranking, test failure severity triage. | +The shared allowance is $1 per America/New_York calendar day. A request reserves $0.002688, derived from 64,000 input tokens at $0.042 per million. SQLite immediate transactions serialize reservations across processes. Crashes and unknown usage retain the reservation. Day rollover uses New York calendar boundaries, including DST. Provider billing remains separately unknown. ---- +The default five-second evaluation deadline includes no more than two attempts. Requests and responses are size bounded. Redirects and endpoint overrides are rejected. Identical successful requests can be reused only in the same client session. Existing MCP processes must restart after credential or policy changes. Separate JEV_HOME directories, unmanaged provider SDKs and standalone TypeScript clients are outside the managed shared ledger. -## 3. Empirical Research Findings (arXiv:2609.29429) +## MCP and installation -Tested across 7,193 model responses and 44 benchmarks (hallucination detection, prompt injection, jailbreaks, data leakage): -1. **0.886 median AUROC**: Outperformed task-specific trained classifiers on 25 of 31 benchmarks without fine-tuning. -2. **Threshold Tuning**: Fitting a decision threshold on as few as 10 domain examples raises median F1 from 0.706 to 0.793. -3. **Selective Classification (Confidence Triage)**: The top 50% most confident decisions reach **93.3% accuracy**, proving that routing low-confidence cases to human/frontier models achieves production-grade precision. -4. **Cost Multiplier**: 11.4 questions per call evaluated at 0.31s latency cost $0.30 vs $18.96 using standard LLM judges (63x cost reduction). +The server validates JSON-RPC 2.0 envelopes, tool arguments and bounded newline-delimited messages. Errors preserve valid request IDs and exclude payloads. Tools expose advisory decisions, risk assessment, evidence-gap assessment, evidence reading and local status. No tool runs the assessed command or approves another tool. ---- - -## 4.

Pass an API key directly from your +application's secret store. It does not read environment variables, store secrets, +implement Windows DPAPI, or enforce the managed harness's shared daily budget. +For Codex/ChatGPT, Command Code, Antigravity, and other installed harnesses, use +the repository's **Python MCP/CLI runtime** instead. Do not install this client as +a second harness runtime or describe its calls as covered by that runtime's cap. + +```typescript +import { JevClient } from "@coding-dev-tools/jev-decision"; + +const client = new JevClient({ apiKey: keyFromYourSecretStore }); +const result = await client.evaluate(sanitizedExcerpt, [{ + id: "relevance", + type: "score", + prompt: "How directly does this excerpt support the stated task?", + criteria: [ + "Unrelated to the task or contradicted by available evidence", + "Useful background but insufficient to answer the task", + "Direct evidence needed to answer the task", + ], +}]); +if (result.status === "ok") { + // Use typed evidence as an advisory input to your normal model or application. + // Existing authorization, executable checks, and task acceptance remain authoritative. +} +``` + +`evaluate(state, questions)` accepts typed questions or the provider's native +question map. Choice criteria need descriptions. Score criteria are ordered +descriptions indexed from zero; the returned score can be fractional and includes +its legend. Noul returns a probability with `confidence: null`. + +Results use the same snake_case status contract as Python: `status`, `source`, +`decisions`, `requested_model`, `resolved_model`, `usage`, `latency_ms`, `attempts`, +`request_id`, `error_code`, and `is_fallback`. Missing credentials, failed requests, +and malformed responses produce `unavailable` with empty decisions. Explicit +offline execution produces `offline` with empty decisions. No regex-based model +decisions are fabricated. Unknown token usage stays `null`. +Usage across a retry remains unknown when an earlier attempt's usage is unknown. + +Calls pin `jev-1.13.0` and the exact official HTTPS endpoint, reject redirects, +bound requests to 24,576 bytes and responses to 262,144 bytes, and have a total +five-second deadline including a maximum of one transient retry. A retry may be +billable; this standalone client does not enforce a spend ceiling. Only send +minimal, sanitized content you are authorized to disclose to TypeSafe. + +Successful results are cached only in the client instance (up to 128 entries); +identical concurrent requests share an invocation. Cache hits report zero new +usage and attempts. `clearCache()` discards completed cached results. No provider +body, source state, or credential is included in returned error data. + +`await guardBashCommand(command, cwd, client)` returns an **advisory risk +assessment**, with `execution_authority: "none"`; it never returns an execution +permission. `await verifyTurnCompletion(evidence, client)` returns advisory +evidence assessment with `task_success_authority: "none"`. Neither helper bypasses +the supplied client. These are intentional breaking corrections from v0.2.0. + +Run `npm ci` and `npm test` for deterministic, mocked-transport Node tests. These +tests do not call TypeSafe and do not establish live model accuracy, latency, +account access, or savings. + +`test/fixtures/contract.json` is the shared Python/TypeScript provider corpus. +`node test/contract-runner.cjs` emits the normalized results for cross-language +regression checks; it always uses a fake transport and never contacts TypeSafe. diff --git a/ts/package-lock.json b/ts/package-lock.json new file mode 100644 index 0000000..c218922 --- /dev/null +++ b/ts/package-lock.json @@ -0,0 +1,51 @@ +{ + "name": "@coding-dev-tools/jev-decision", + "version": "0.3.0", + "lockfileVersion": 3, + "requires": true, + "packages": { + "": { + "name": "@coding-dev-tools/jev-decision", + "version": "0.3.0", + "license": "MIT", + "devDependencies": { + "@types/node": "^20.0.0", + "typescript": "^5.4.0" + }, + "engines": { + "node": ">=20" + } + }, + "node_modules/@types/node": { + "version": "20.19.43", + "resolved": "https://registry.npmjs.org/@types/node/-/node-20.19.43.tgz", + "integrity": "sha512-6oYBAi5ikg4Pl+kGsoYtawUMBT2zZMCvPNF7pVLnHZfd1zf38DRiWn/gT01RYCdUqkv7Fhr+C9ot4/tb+2sVvA==", + "dev": true, + "license": "MIT", + "dependencies": { + "undici-types": "~6.21.0" + } + }, + "node_modules/typescript": { + "version": "5.9.3", + "resolved": "https://registry.npmjs.org/typescript/-/typescript-5.9.3.tgz", + "integrity": "sha512-jl1vZzPDinLr9eUt3J/t7V6FgNEw9QjvBPdysz9KfQDD41fQrC2Y4vKQdiaUpFT4bXlb1RHhLpp8wtm6M5TgSw==", + "dev": true, + "license": "Apache-2.0", + "bin": { + "tsc": "bin/tsc", + "tsserver": "bin/tsserver" + }, + "engines": { + "node": ">=14.17" + } + }, + "node_modules/undici-types": { + "version": "6.21.0", + "resolved": "https://registry.npmjs.org/undici-types/-/undici-types-6.21.0.tgz", + "integrity": "sha512-iwDZqg0QAGrg9Rav5H4n0M64c3mkR59cJ6wQp+7C4nI0gsmExaedaYLNO44eT4AtBBwjbTiGPMlt2Md0T9H9JQ==", + "dev": true, + "license": "MIT" + } + } +} diff --git a/ts/package.json b/ts/package.json index 146dc6d..2b579e7 100644 --- a/ts/package.json +++ b/ts/package.json @@ -1,24 +1,25 @@ { "name": "@coding-dev-tools/jev-decision", - "version": "0.2.0", - "description": "Zero-dependency System 1 decision engine and guardrails for Jev (TypeSafe AI) in TypeScript", + "version": "0.3.0", + "description": "Strict typed advisory TypeSafe API client; managed harness controls use the Python runtime", "main": "dist/index.js", "types": "dist/index.d.ts", "scripts": { "build": "tsc", - "test": "node --test dist/**/*.test.js" + "test": "npm run build && node --test test/client.test.cjs" }, "keywords": [ "jev", "typesafe-ai", "system-1", "ai-agents", - "guardrails", - "token-optimization", + "advisory-decisions", "mcp" ], "author": "Coding-Dev-Tools", "license": "MIT", + "engines": { "node": ">=20" }, + "files": ["dist/index.js", "dist/index.d.ts", "README.md"], "devDependencies": { "typescript": "^5.4.0", "@types/node": "^20.0.0" diff --git a/ts/src/index.ts b/ts/src/index.ts index db0000d..bee74a0 100644 --- a/ts/src/index.ts +++ b/ts/src/index.ts @@ -1,309 +1,543 @@ /** - * Zero-dependency TypeScript client, primitives, and harness guardrails for Jev (TypeSafe AI). + * Explicit, unmanaged TypeSafe API client.

These are engineering bounds, not demonstrated optimal settings. -The installer supports native MCP configuration for Codex, Command Code, Antigravity, Claude Code, Cursor, OpenCode and Crush. Pi, Hermes, OMP and OpenClaude use a client-supported skill invoking the same CLI. Existing profiles without a verified runnable client remain inactive.

Local stdio installation does not connect hosted ChatGPT. A tunnel must forward to this managed runtime and its ledger, and depends on this computer remaining online. See [OpenAI's tunnel requirements](https://developers.openai.com/api/docs/guides/secure-mcp-tunnels). +The managed runtime pins `jev-1.13.0`, sends only to the official HTTPS endpoint, reserves worst-case cost before each attempt, and permits at most one transient retry within the deadline. Budget reservation and settlement share that deadline. Crashes, unknown usage, and unfinished settlement retain conservative reservations. Timezone changes preserve the active accounting period. Separate runtime homes or standalone SDK calls have separate budgets. -Run `python -m pytest -q` and, under `ts`, `npm ci` followed by `npm test`.

See https://docs.typesafe.ai/api and https://docs.typesafe.ai/models for provider behavior and pricing. Local policy is stricter than the provider maximum to bound transmission, latency and accounting. +The managed runtime pins `jev-1.13.0` and the exact official TypeSafe HTTPS endpoint. Native questions and complete typed answers follow the [provider API](https://docs.typesafe.ai/api); local limits bound latency, transmission and conservative accounting. -## Data flow +## Client results -A harness invokes an absolute installed launcher. The runtime loads public policy and a Windows CurrentUser DPAPI credential, sanitizes bounded state and questions, and checks the session cache. For a provider attempt it reserves the maximum documented request cost in a shared SQLite transaction, sends only to the official HTTPS endpoint, and validates the entire typed response. Known input usage settles the reservation; absent or invalid usage retains it. A retry reserves again. Diagnostics contain no key, state or raw response. +Python and TypeScript expose `status`, `source`, `decisions`, requested/resolved model, usage, latency, attempts, request ID and a content-free error code. Unknown usage remains null, including retries with unknown earlier usage. Cache hits report zero new attempts/usage. Native Choice descriptions may be null. Score preserves fractional rubric positions, legends and provider rounding; it does not renormalize the wire response. Invalid or missing answers reject the whole batch. -The result records status, source, requested and resolved model, optional usage, attempts and a fixed error code. Missing or malformed answers reject the complete response. Question IDs are unique and complete. Noul has no provider confidence field. Choice and Score require finite valid probability distributions. Scores retain fractional values and descriptive legends. +Offline, missing credentials, expired deadlines and provider failures return no synthetic decisions. Command assessment cannot grant permission, completion assessment cannot certify execution, and advice cannot overwrite canonical benchmark or memory evidence. -## Authority +## Execution and accounting -Risk assessments never grant execution permission. Evidence assessments never certify completion. Jev output cannot change canonical benchmark grades, evidence artifacts or memory by itself. Offline and unavailable states carry no synthetic decision. Consumers resume their ordinary model and executable verification workflow. +Fresh runtime loads stay disabled until configured. Explicit library construction can opt in. One monotonic deadline covers preprocessing, reservation, connection, transmission, bounded response reading, validation and settlement. A late connection cannot transmit after cancellation. Retry-After seconds/dates, transient failures including 529 and jitter stay inside one optional retry. Unknown or unfinished accounting retains a conservative reservation; it never creates a success/cache entry after the deadline. -## Evidence selection +Before every request, SQLite serializes a maximum-request reservation across processes sharing `JEV_HOME`. The configured nonnegative daily budget can exceed the former personal $1 setting; zero disables calls. UTC is the portable default. v1 settings keep their enabled state, budget, New York timezone and ledger history. Timezone changes take effect after the active accounting period so they cannot reset spend early. Provider usage and modeled cost remain distinct from invoices. -Saved UTF-8 evidence can be read through approved workspace roots. Resolve and check paths, reject sensitive names, enforce byte limits, sanitize excerpts, and retain original SHA-256 and source line locations. Large windows that exceed provider bounds remain available locally rather than being truncated into misleading evidence. All bounded windows are assessed together against complete shared state. +DPAPI protects Windows credentials. Optional OS keyring backends support macOS Keychain/Linux Secret Service; plaintext fallbacks are refused. An explicit environment variable reference supports headless use. Status inspects presence metadata without unlocking a keychain; it never claims authentication. TypeScript is an explicit unmanaged client and does not share Python's local cap. -Pruning is off by default. Even when explicitly enabled after calibration, uncertain assessments retain content. Failure details, test summaries, exit codes, diff boundaries and original artifacts remain protected. Actual token savings require primary-model telemetry; byte counts are not tokens. A tool cannot remove text already consumed by a model. +## Evidence and profiles -## Accounting and transport +`off` makes no semantic calls. `shadow` scores bounded eligible records while retaining evidence. `select` requires the exact recoverable original, a qualified profile/report, and matching workload identity. Unknown formats, unprocessed spans and uncertain answers remain intact. File reads preserve source line positions through redaction and expose bounded pagination and changed-hash rejection. Originals are never automatically removed. -The shared allowance is $1 per America/New_York calendar day. A request reserves $0.002688, derived from 64,000 input tokens at $0.042 per million. SQLite immediate transactions serialize reservations across processes. Crashes and unknown usage retain the reservation. Day rollover uses New York calendar boundaries, including DST. Provider billing remains separately unknown. +The initial limits are 16 questions/~16 KiB per batch, two concurrent evaluations and a five-second selection deadline. Critical structural groups and adjacent context remain protected. These bounds are engineering defaults requiring workload calibration. Omission markers, JSON envelopes, retries, recovery and Jev all count toward measurement. -The default five-second evaluation deadline includes no more than two attempts. Requests and responses are size bounded. Redirects and endpoint overrides are rejected. Identical successful requests can be reused only in the same client session. Existing MCP processes must restart after credential or policy changes. Separate JEV_HOME directories, unmanaged provider SDKs and standalone TypeScript clients are outside the managed shared ledger. +Qualification recomputes held-out metrics rather than trusting summary flags. It binds source/label/report hashes, Jev model/rubric/thresholds/source classes, explicit primary model/harness identity, independent task/project groups, matched arms/cache strata and campaign budget. It requires retained critical facts, no observed task-success loss, positive net tokens and modeled cost, and no p95 task-time increase. See [evaluation](EVALUATION.md). ## MCP and installation -The server validates JSON-RPC 2.0 envelopes, tool arguments and bounded newline-delimited messages. Errors preserve valid request IDs and exclude payloads. Tools expose advisory decisions, risk assessment, evidence-gap assessment, evidence reading and local status. No tool runs the assessed command or approves another tool. +The optional official Python MCP SDK v2 owns protocol negotiation, JSON-RPC framing and errors. It serves legacy and current clients with complete tool schemas. A bounded byte reader rejects oversized/invalid frames without echoing their payload. UTF-8 is explicit for Windows pipes. Core library/JSON CLI imports do not load the SDK. -The installer records only Jev-owned changes, previews updates, keeps private backups and restores matching entries selectively. Native MCP clients share the installed Python runtime. CLI skills use that same absolute executable. Hosted ChatGPT needs a separately authorized private OpenAI Secure MCP Tunnel forwarding to the same runtime. Configuration success is distinct from credential authentication, actual client operation and demonstrated benefit. +Selected user/project installation previews and applies Jev-owned entries only. Restoration keeps unrelated settings and reports modified conflicts. Absolute launchers and runtime-home bindings keep processes on one credential/ledger. Configuration, connection, authentication, actual invocation and workload qualification are separate states.

An external edit to an owned entry remains a conflict rather than being silently restored. + +The generated entry binds an absolute interpreter and `JEV_HOME`. An environment credential uses `${TYPESAFE_API_KEY:-}` (or your selected variable name), never its value. The empty fallback allows credential-free off reads. Supply the real variable in the client launch environment only when enabling provider use, or choose the supported OS vault in `jev setup`. The installed skill's CLI command also binds the absolute runtime home. + +To restore this project integration, preview first, then apply: + +```powershell +& $jevPython -I -m jev_decision.cli --runtime-home $jevState harness restore --target command-code --scope project --project-root $projectRoot --dry-run +& $jevPython -I -m jev_decision.cli --runtime-home $jevState harness restore --target command-code --scope project --project-root $projectRoot --apply +``` + +Restoration uses saved ownership records, retains unrelated edits, and reports conflicts instead of overwriting changed managed content. It does not erase the runtime, credentials, budget ledger, or captured evidence. A user-scope restore uses `--scope user` with no project-root argument. + +## Invoke the workflow + +Reload the client, inspect `/mcp` for the `jev` connection, and inspect `/skills` for `jev-advice`. Complete any normal workspace trust or tool approval prompts. The skill sets `disable-model-invocation: true`; invoke it explicitly instead of expecting automatic discovery from the model's skill catalog. [Command Code skills](https://commandcode.ai/docs/skills#skills-specification) + +For an existing saved log, type a path as ordinary text, without attaching the entire file: + +```text +/jev-advice C:/work/example/.jev-captures/run-001/stderr.log Explain the first failed test. Use off mode; do not rerun the producer. +``` + +The skill directs the agent to call `mcp__jev__jev_read_evidence` with a bounded page. The equivalent direct CLI call is: + +```powershell +& $jevPython -I -m jev_decision.cli --runtime-home $jevState evidence --file 'C:/work/example/.jev-captures/run-001/stderr.log' --goal 'Explain the first failed test' --mode off --max-lines 200 --json +``` + +For a command that has not run, use the repository's [capture helper](../examples/capture.py) through the ordinary shell tool, under the same permissions as the producer. It executes an argv command without a shell and saves stdout, stderr, exit status, sizes and hashes. This synthetic example demonstrates a failed producer while returning only a capture reference: + +```powershell +& $jevPython 'C:/src/jev-decision/examples/capture.py' --directory 'C:/work/example/.jev-captures/run-001' -- $jevPython -c 'import sys; print("collected 3 tests"); print("FAILED test_export", file=sys.stderr); sys.exit(7)' +``` + +Use a new capture directory for each run. Retain the helper's exit status `7` and `capture.json`; the helper does not reinterpret success. Read both saved streams when relevant. Never pipe the original log through the agent and then claim later scoring saved its context tokens. For output above the evidence reader's file limit, retain the original and produce bounded, provenance-preserving chunks before reading; a truncated excerpt is not a complete run. + +## Off, shadow, and qualified select + +`off` is the initial policy. To run an explicitly authorized shadow trial, first choose a nonzero daily cap and save the mode. For example, the operator can repeat setup with `--daily-budget 0.25 --selection-mode shadow` after approving that cap and configuring credentials. A later evidence call may request `--mode shadow`; it retains the entire sanitized page while collecting scoring metadata. Per-call options cannot upgrade a saved `off` policy. + +`select` requires a reviewed profile configured by the operator and [qualification evidence](EVALUATION.md). Pass an independently established workload identity with the real `harness`, `harness_version`, `primary_model`, and `primary_provider`; use MCP's `workload` object or CLI `--workload /absolute/workload.json`. Do not fill these fields by copying a profile. No Command Code selection profile ships, and no saved policy is upgraded by this skill. + +Keep `source_sha256` and page metadata. Retrieve an omitted or later range with `--mode off --start-line N --max-lines M --expected-source-sha256 HASH`. Read errors, contradictions, exit status, and any required unread tail before concluding. A redacted or selected page is advisory evidence, never authorization or a replacement for executed verification. See [evidence behavior](EVIDENCE.md) for fallback and recovery details. + +## Why this uses a skill + +The current [mod contract](https://commandcode.ai/docs/mods#hooks-and-events) exposes `afterToolCall`, which can replace the result before it is committed to model context. That is a plausible future adapter, but a generic tool result does not establish the immutable source, approved upload scope, matching workload identity, and qualified omission policy this runtime requires. Mods are unsandboxed trusted code and their API is experimental. This integration instead exposes an explicit saved-artifact workflow through existing tools; it adds no permission grants, automatic retries, or event hooks. + +## Evidence checked on 2026-09-28 + +The locally installed npm package reported **`command-code` 1.66.0** in its `package.json`.

Users no longer need a checkout helper to keep producer output out of model context. Capture preserves argv, both binary streams, hashes and producer status; it prints only a manifest reference and does not load Jev configuration or credentials. The ordinary shell permission flow authorizes the producer. No MCP tool executes commands. + +The Command Code guide and packaged skills use this entry point. Generic advice also reflects the provider's [documented Jev 1.13 limitations](https://docs.typesafe.ai/model-jaggedness/jev-1.13): keep exact arithmetic in code, minimize irrelevant state, ask direct questions, and calibrate thresholds for each question type. The [provider evidence-filtering example](https://docs.typesafe.ai/cookbooks/classifying_rag_passages) is workload guidance, not a universal threshold or savings guarantee. + +## Validation and release gates + +Local Windows verification used Python 3.12.10 and Node 24.15.0: **520 Python tests passed, one symlink-privilege test skipped; 86 TypeScript tests passed**. Shared native fixtures run against both implementations. Full configured Ruff rules and Git whitespace checks passed. Focused client and evidence fixes received independent re-review with no remaining findings. + +The package checker builds wheel/source artifacts and installs each outside the checkout, then invokes packaged capture, Command Code skill installation/restoration, and legacy/current MCP subprocesses. The npm checker packs and installs outside the checkout. CI performs these checks on Windows, macOS and Linux and tests core Python 3.9–3.13; read the exact PR-head check results before release. Artifact creation does not publish a package or merge the PR. + +The refreshed offline report still has four synthetic source tasks and 16 matched arm records. It remains ineligible with `live_evaluation_required`. Old profiles are invalidated by the changed protection policy's rubric hash. + +| Gate | Release position | +| --- | --- | +| Portable advisory APIs, setup, capture, protected recovery and local tests | Implemented and validated offline | +| Cross-platform clean distributions | Required exact-head CI gate | +| Actual named-client/version invocation and OS vault usability | Deployment-specific, not established by these fixtures | +| Automatic omission, live task success and net token/cost/time improvement | Requires an independently labeled, budgeted campaign for the exact workload; disabled until qualified | +| Publication and merge | Separate release actions; not performed by this review | + +Users can integrate and collect measurements now.

Every generated MCP entry and skill command on macOS/Linux therefore failed to start. Windows keeps its resolved physical path for MSIX-virtualized runtimes. Claude Code passes an unset ${NAME} through as literal text, so its environment reference now uses the ${NAME:-} empty default like Command Code. The package check now launches the generated interpreter and imports the package, so CI exercises the actual entry instead of sys.executable.

The fast path for a System 1 check is the harness's own pre-tool hook. `jev hook run HARNESS` reads one hook payload (Claude Code, Command Code, Codex, Cursor, Gemini CLI) and can only add friction: - ask-capable hooks (Claude Code, Cursor) get "ask", forcing the normal approval prompt for a flagged command; - allow/deny-only hooks (Command Code, Codex, Gemini CLI) get "deny" with a reason, by default only in no-prompt sessions (bypass/yolo), so a person never loses the chance to approve; --when always blocks in every mode. It never answers "allow". Simple read-only commands (ls, cat, git status, ... without shell syntax or private-file arguments) skip the request. Every local failure (no setup, no key, budget, timeout, malformed input, stale arguments) exits 0 with no decision, because exit 2 means block. JEV_HOOK=off disables it; JEV_HOOK_THRESHOLD tunes it (default 0.8). `jev hook config HARNESS` prints the exact settings fragment to merge. The Python command guard now gives every Choice category and the Noul explicit criteria (provider guidance; matches the TypeScript guard) and reports category_probabilities.

jev_decide input schema Most MCP clients send every tool's input schema to the primary model on each request. jev_decide advertised both the native map and legacy array forms (6.5 KB), so the six tools cost about 10 KB (~2.5K tokens) of model context per request. Discovery now advertises only the preferred array form (2.7 KB; ~960 fewer tokens per request across the tool list), while the server still validates calls against the complete schema, so native ID-keyed maps and legacy prompt/options/scale inputs keep working.

Existing clients need a reload. `doctor --live` sends one budgeted synthetic request and verifies provider authentication only; it does not prove the named harness invoked Jev. +The hook is **escalate-only**. It can force the harness's normal approval prompt (Claude Code, Cursor), or block a flagged command with a reason (Command Code, Codex, Gemini CLI). By default it blocks only in sessions that run without approval prompts. It never approves anything. Simple read-only commands such as `ls` or `git status` skip the request. Any local failure leaves the harness unchanged, and `JEV_HOOK=off` turns the hook off. See [docs/HOOKS.md](docs/HOOKS.md). -## Small, typed decisions +## Use it from code ```python from jev_decision import JevClient -client = JevClient() # Loads the explicitly configured managed runtime. +client = JevClient() # saved `jev setup` runtime, or JevClient(api_key=...) / TYPESAFE_API_KEY before setup batch = client.evaluate( {"request": "Export needs a preview before downloading."}, - {"intent": {"type": "choice", "instructions": "Classify the requested change.", - "criteria": {"feature": "New behavior", "bug": "Broken existing behavior", "unclear": None}}}, + [{"id": "intent", "type": "choice", "instructions": "Classify the requested change.", + "criteria": {"feature": "Adds new behavior", "bug": "Fixes broken existing behavior", "unclear": None}}], ) if batch.status == "ok": - print(batch.get_choice("intent").selected) # Advice, not permission. + print(batch.get_choice("intent").selected, batch.get_choice("intent").probabilities) else: - print(batch.status, batch.error_code) # Continue the normal workflow. + print(batch.status, batch.error_code) # carry on without Jev ``` -Runnable JSON examples: [classification](examples/classify.json), [evidence relevance](examples/relevance.json), [routing](examples/route.json), and [verification gaps](examples/verification-gap.json). Run `jev decide --file examples/route.json` after setup. Skip Jev when a deterministic rule or test already answers the question. - -Use non-sensitive question IDs and Choice labels. Recognizable secrets in Python IDs and labels are redacted before transmission, and redaction collisions reject the request. Successful results restore the caller's original IDs and labels, including cached results; those values are intentionally part of the local result. TypeScript sanitizes question IDs; applications own body and criterion sanitization. - -Choice supports native null descriptions. Score uses 2–10 ordered descriptive levels and preserves fractional values and legends. Noul returns a probability; separate confidence is unknown. Missing usage stays `null`. Python and TypeScript share contract fixtures, including valid provider probability rounding. - -## Evidence before model ingestion +The native ID-keyed map (`{"intent": {"type": "choice", ...}}`) and the typed `NoulQuestion`/`ChoiceQuestion`/`ScoreQuestion` classes also work. Ready-made helpers are `guard_bash_command`, `verify_turn_completion`, `classify_memory_relation`, and `prune_tool_output`. Passing a key to a library client before any `jev setup` counts as opting in, with the default $1/day cap on the shared ledger. The CLI and MCP server stay offline until setup. -Capture output to original artifacts first, then return references to the agent. [Complete PowerShell/POSIX examples](docs/EVIDENCE.md) preserve stdout, stderr, and producer exit status.

Supported records are grouped before scoring; tracebacks, test summaries, diff hunks, warnings, statuses, and adjacent context remain protected.

These are engineering bounds, not demonstrated optimal settings. +A large log only saves context tokens if it never enters the model's context. `jev capture --directory /abs/new-dir -- pytest` runs the command and saves stdout, stderr, hashes, and the exit status. It prints only a small reference. `jev evidence` / `jev_read_evidence` then pages through the saved file inside approved workspace roots, with secrets redacted and original line numbers preserved. -## Accounting and qualification +Evidence **selection** (dropping low-relevance log spans) is off by default. **No workload ships qualified for automatic omission.** `shadow` mode measures, and `select` requires a locally qualified profile built with the [evaluation workflow](docs/EVALUATION.md).

Separate runtime homes or standalone SDK calls have separate budgets. +## Safety and accounting -[Evaluation instructions](docs/EVALUATION.md) compare unchanged output, deterministic-only, shadow, and selection arms. Qualification requires all labeled critical facts, no observed task-success loss, positive net tokens and modeled cost after Jev, and no p95 task-time increase. Reports bind source/label hashes, model/rubric/thresholds, harness versions, independent held-out source groups, cache conditions, and the explicit campaign budget. Inconclusive results stay in measurement mode. Provider usage and modeled cost are not invoices. +- The model (`jev-1.13.0`) and the official HTTPS endpoint are pinned. There is no proxy discovery and no redirect following. +- Each attempt reserves its worst-case cost in a SQLite ledger shared by every process with the same `JEV_HOME`. There is at most one transient retry within a single deadline. +- Keys live in DPAPI, the OS keychain, or an environment variable you name. Harness configs contain only variable references. Unexpanded `${NAME}` placeholders are treated as missing keys. +- Question IDs, labels, and state are scanned for recognizable secrets and redacted before they leave the machine. -## Develop and prepare release artifacts +## Development ```sh -python -m pip install '.[test,mcp,setup]' build +python -m pip install -e ".[test,mcp,setup]" build python -m pytest -q -python scripts/evaluate_evidence.py --dataset examples/evaluation/dataset.json --offline --output /absolute/new-offline-report.json -python scripts/check_packages.py --output /absolute/new-release-candidate-directory -cd ts -npm ci -npm test -npm run check:package +python scripts/check_packages.py --output /abs/new-dir # wheel/sdist installed outside the checkout +cd ts && npm ci && npm test && npm run check:package ``` -CI tests Python 3.9–3.13 on Windows/macOS/Linux, enables optional MCP tests on supported Python versions, and installs wheel, source, and npm packages outside the checkout.

No paid provider request was made, and no user harness profile or credential was changed. + +## Defects found and fixed + +| Severity | Issue | Fix | +| --- | --- | --- | +| High | On macOS/Linux every generated MCP entry and skill command used `Path(sys.executable).resolve()`. In a POSIX venv, pipx or uv tool environment, `bin/python` is a symlink to the base interpreter, which cannot import `jev_decision`, so the MCP server failed to start with `No module named jev_decision`. Windows venv interpreters are real files, which hid the bug. The tests asserted the same resolved path. | Entries keep the environment's unresolved interpreter on POSIX; Windows keeps its resolved path for MSIX runtimes. A regression test uses a symlinked interpreter, and `check_packages.py` now launches the generated interpreter. An end-to-end run from a `uv tool install` (symlinked `bin/python`) completed an MCP handshake through the generated `.mcp.json` entry, where the resolved interpreter failed. | +| Medium | A library `JevClient(api_key=...)`, or `JevClient()` with `TYPESAFE_API_KEY`, returned `runtime_disabled` until `jev setup` had run, so the README's first Python example did nothing. | Supplying a key to a library client before any saved configuration opts in with the default daily cap and shared ledger. The CLI and MCP still stay offline until setup, and a saved configuration (including a disabled one) always wins. | +| Medium | Claude Code entries used `${NAME}` without a default. Claude Code passes an unset reference through as literal text, which then passed the printable-ASCII key check, failed authentication on every call, and left a worst-case budget hold. | Claude Code entries use `${NAME:-}`. The environment loader and presence status treat `${…}`, `{env:…}`, `$NAME` and `%NAME%` values as absent keys. Storage and the TypeScript constructor reject them. | +| Medium | The evidence reader screened credential names across the whole absolute path, so any workspace under a directory such as `auth-service/`, `oauth_app/` or `secrets-manager/` refused every read. | Names are screened below the most specific approved root. Denied names inside the root (`.env`, `.git`, `secrets/`, `*.pem`, `credentials.*`) are still refused, and exact-path recovery keeps the whole-path screen. | +| Low | `jev guard`, MCP `jev_guard_command` and the hook asked an unlabeled Choice (option equals label), against the provider's guidance to state exact conditions. The TypeScript guard already used descriptive criteria. | Every category and the risk Noul have explicit criteria, and the result adds `category_probabilities`. | +| Low | Zero-budget and fresh runtimes reported a bare `runtime_disabled`. | CLI results and `doctor --live` include a corrective hint. | +| Low | The version string was repeated in seven places. | `jev_decision/_version.py` is the single Python source (read dynamically by setuptools). A test keeps the npm package, lockfile and User-Agent in step. | + +## Harness integration improvements + +- **Pre-execution guard (`jev hook`).** MCP-only integration relied on the primary model choosing to call `jev_guard_command`, which spends its tokens and depends on its compliance. The adapter reads Claude Code, Command Code, Codex, Cursor and Gemini CLI pre-tool payloads. It returns `ask` where hooks support it, and otherwise `deny`, by default only in no-prompt sessions. It never returns `allow`, skips plain in-project read-only commands without a request, and exits 0 with no decision on every local failure (exit 2 means "block" to several harnesses). `jev hook config HARNESS` prints the fragment to merge. See [HOOKS.md](../HOOKS.md). +- **Smaller MCP context footprint.** Discovery advertises a compact `jev_decide` input schema (6.5 KB → 2.7 KB; the model-facing tool list drops from 10.2 KB to 6.3 KB, about 960 tokens per request in clients that send every schema). The server still validates against the complete schema, so native maps and legacy fields keep working. +- **One question format everywhere.** Python accepts the same plain `{id, type, instructions, criteria}` objects as MCP, the CLI and TypeScript. +- **Docs.** The README now starts with a four-step quickstart and a harness table; qualification caveats have their own section.

Long-lived MCP servers would benefit from a pooled HTTPS connection and a persistent ledger connection. These touch the heavily tested deadline code, so they are left for a focused follow-up. +- **Ledger retention.** Reservation rows are never pruned. A frequently firing hook could grow the ledger by tens of MB per year, so a bounded prune at period rollover is worth adding. +- **`jev_prune_output`.** The tool makes the agent resend text that is already in context, which costs primary-model output tokens. Its description says so. Consider hiding it from discovery unless shadow or select mode is configured. +- **Automatic hook installation.** `jev hook config` prints the fragment rather than editing settings, because hook entries are array items that the ownership-tracked installer does not manage yet. +- **Node 20** reached end of life in April 2026. `engines` still allows it, but CI now tests Node 22 and 24.
