It collects sanitized evaluation outcomes (validated continuity archives + evaluator manifests) into an append-only ledger (re-collecting skips, history is never rewritten; integrity-suspect sources are refused), classifies recorded weaknesses into instructions / references / validation / recovery through a versioned keyword classifier, generates proposals that are **refused unless mapped to recorded failed evaluation cases**, verifies each candidate inside detached git worktrees under the OS temp dir (the active repository and active skill are never touched; `.opencode` data dirs are refused outright), runs the full regression suite on both sides with no shell (`spawnSync`) - by default `scripts/validate.mjs --all` and `tests/harness/selftest.mjs` - and compares every `Summary` tier deterministically: any regression (lower tier pass count, higher failures, missing tier, nonzero exit) hard-rejects the candidate (verdict `REJECTED`, proposal permanently unapprovable, evidence preserved); adoption requires a measurable improvement (strictly more passing checks, zero regressions) **and** an explicit named approver (`--approved-by`), recorded as a decision only - `appliedByTool` is always `false`, nothing is published automatically, and applying a candidate is a manual, human-reviewable step. Model-generated claims are never evidence: the optional `claim` field is carried but labeled `evidence: false`, and verdicts rest on deterministic suite counts only (disclosed proxy limitation: tier counts are structural - renames/splits read as regressions; the bias is conservative). All records are schema-pinned v1 with content-hash ids, secret-shape scanning, and atomic writes. Honest scope: LOOP does not learn model weights and holds no permanent autonomous intelligence - evolution here means improving instruction/reference/validation/recovery *artifacts* through human-approved, regression-gated changes; one candidate/commit-pair per comparison, not a statistical model of LOOP quality. + +- **Model capability evaluation** (`scripts/model-eval.mjs`; docs `docs/model-eval.md`; pinned task set `tests/model-eval/taskset.v1.json`): evidence-backed evaluation of LOOP-compatible AI models on identical tasks in controlled environments. Eight capability dimensions (instruction-adherence, tool-calling, coding-correctness, context-management, verification-accuracy, security-reasoning, recovery-behavior, completion-evaluator-adherence) are measured from completed evaluation records that store provider, model identifier, test date, environment, per-task `PASS|FAIL|PARTIAL` results, and re-inspectable evidence paths - never from marketing descriptions (unknown/promotional record fields are refused; records are allowlist-strict). The task set is version-pinned (`v1.0.0`) with a SHA-256-derived `taskSetHash` written into every record, so comparisons between records that did not execute identical tasks are refused rather than silently compared, and differing environments are flagged as directional, never controlled. No ranking is derivable by construction: comparisons emit per-dimension observed counts with an explicit non-ranking disclaimer, and profiles emit counts plus a sample-size classification only (dimensions below `MIN_TASKS_PER_DIMENSION` = 3 tasks are `INSUFFICIENT_SAMPLE`, never scored); completing a record requires an explicit `limitations` statement, carried into every derived profile and comparison. Fail-closed record handling (unknown-field refusal, secret-shape scanner on every write, atomic tmp+fsync+rename writes), deterministic runIds with duplicate refusal, zero external dependencies. No credentials are ever handled or stored (runs are operator-gated with operator-supplied credentials), no provider is called or switched automatically, and the core project tests exercise the framework offline on fixture records with no paid API. **Token-gated limit:** no real model capability profiles ship in this release - zero profiles exist in the repository, and none are inferred from vendor claims; producing one requires an operator-initiated evaluation run. + +- **Task profiles** (`scripts/profiles.mjs`; docs `docs/profiles.md`; modular references `references/profiles/{build,debug,refactor,audit,migrate}.md`): adaptive engineering methodologies for the nine-stage loop. Five profiles - BUILD (new functionality), DEBUG (root-cause investigation), REFACTOR (behavior-preserving structure), AUDIT (read-only independent assessment; fixes require explicit operator authorization), MIGRATE (controlled technology/data transitions with rehearsed rollback) - each defining the same seven dimensions: required inputs, relevant analysis stages, verification methods, risk priorities, completion criteria, forbidden shortcuts, and expected evidence. Profiles are selected from explicit user intent only (`--profile ` on `/loop`, resolved deterministically by the zero-dependency resolver - unknown names are refused with the valid list, never silently defaulted, and the run continues as the generic loop) and never override the task scope: only the `--profile` flag is stripped, everything else in the task text passes through verbatim. Universal safeguards bind every profile (anchored in each reference and pinned by the validator): the nine stages and the hard safety rules apply unchanged; a profile only adds specificity, never removes a stage or loosens Stage 8 evidence requirements. Resolver behavior is covered by real-module and CLI checks, and every reference file is validator-pinned for all seven dimensions plus the safeguard anchor. + +- **LOOP Evaluator** (`scripts/evaluator.mjs`; docs `docs/evaluator.md`): deterministic, evidence-based completion evaluation. A run records what it actually executed into `/.loop/verification.json` — criteria (MUST/SHOULD/COULD with optional deliverable artifact paths), evidence verdicts with optional re-executable argv commands, severity-classified findings, and blockers — and the evaluator derives one of `PASS | FAIL | BLOCKED | NEEDS_REVIEW` from that manifest (exit codes 0/1/2/3). A model-written completion statement carries zero weight: advisory-only evidence caps at `NEEDS_REVIEW`, missing verification derives `BLOCKED` (never a silent PASS), and `--fresh` re-executes every deterministic PASS command, letting the real exit code override recorded claims. Zero external dependencies; reuses the continuity helper's atomic write, secret scanner (both fail-closed), and state inspection; binds to the live continuity run's `taskId` and refuses cross-run/planted manifests. Integrated via a Stage 8 touchpoint in the skill and a completion-evidence section in the continuity reference — the nine-stage methodology is unchanged. + +- **LOOP Continuity** (ADR 0002, `docs/adr/0002-loop-continuity.md`; user guide `docs/continuity.md`): durable run state for the nine-stage workflow. A run's state (`ACTIVE | PAUSED | RECOVERY_REQUIRED | BLOCKED | COMPLETED | CANCELLED`, with file integrity tracked separately as `VALID | SUSPECTED_STALE | CORRUPT`) is validated and persisted by an optional, zero-external-dependency helper (`scripts/continuity.mjs`, Node >= 16.7) into `/.loop/continuity.json` - atomic writes (temp + fsync + rename, recoverable temps, and a `repair` path that only removes provably superseded leftovers), sanitized remote-URL identity fingerprints, cancel/complete archiving to `.loop/archive/` with terminal evidence retained (never silently deleted), and a best-effort secret-shape scanner that refuses to persist matches (limits documented in the file header). Four thin commands orchestrate the lifecycle: `/loop-status` (read-only state + git cross-check), `/loop-pause` (stage-boundary pause with recorded next step), `/loop-resume` (gates: integrity, identity, no automatic resumption of an interrupted ACTIVE run, read-only reconciliation first, explicit operator approval, then restore into the nine-stage loop at the recorded stage), and `/loop-cancel` (cancel + archive; reasons retained). Cross-session and cross-model recovery works because the checkpoint is plain files, not session memory; provider-quota or context-limit death is recovered through the same manual resume path. Installers install the helper (`/scripts/continuity.mjs`) and remove it on uninstall. Documented limits: checkpoint writing is prompt-level discipline measured by the behavioral harness (never guaranteed), interrupted stages are not promised bounded loss, one live run per project is an operational rule (generation detects stale snapshots; not a lock), and `--force` does not exist in this release. + +- **Continuity reference** (`.opencode/skills/loop-engine/references/continuity.md`): agent-facing protocol - helper search order with the `BLOCKED` degradation contract, state vocabulary, write-before-act timing, resume-gate order, and archive rule. + +### Fixed + +- **Identity mismatch enforcement gap** (found by the new real-module tests, fixed before any command shipped): the helper detected a project identity mismatch but only *enforced* it when the caller supplied an expected root; a direct state-mutating call without that argument could operate on another project's checkpoint. Mutating operations now derive the authority from the project root they were invoked on. + +### Changed + +- SKILL.md: Stage 0 refuses a silent second run while a live checkpoint exists and, with the helper available, writes stage-entry checkpoints (write-before-act); Stage 8 records completion through the helper and lets early stops stay PAUSED for later `/loop-resume`. Behavior without the helper is unchanged (continuity operations report `BLOCKED`). +- Validation grew with the features: structural checks for the four continuity commands (frontmatter, description, `$ARGUMENTS`, reference route, `BLOCKED` path, and the absence of any override flag), helper content checks (zero-dep, no-network, status vocabulary, documented scan limits), installer matrix assertions for helper install/uninstall byte-identity, and nine new defect-injection mutations. The behavioral self-test grew from 79 to 113 checks, importing the actual helper module (no mirrored test-only model). + ## [0.3.1] - 2026-11-05 Reliability, safety, and engineering-quality hardening of the behavioral runner. diff --git a/README.md b/README.md index b507635..d07c274 100644 --- a/README.md +++ b/README.md @@ -124,6 +124,19 @@ Mode behavior: > **Honesty note:** iteration limits and modes are *prompt-level execution guidance*, not a runtime controller.

Corrupt or unsupported +schema-version state is **never silently overwritten, emptied, or deleted** +(oc-loop's silent-empty-store behavior is explicitly rejected) — it is +**preserved in place, byte-for-byte**, and the run reports `BLOCKED` with the +evidence — `inspect`, `transition`, and `update` refuse to mutate it. Moving a corrupt +file aside (e.g. renaming `*.corrupt-`) happens **only on +explicit operator instruction** — no continuity operation relocates state +automatically. That is the resolution of the earlier draft's "(e.g. renamed +...)" wording: preservation is automatic; relocation is manual. + +### 3. Recovery safety — no automatic resume + +A found `ACTIVE` or `PAUSED` state file **never resumes execution +automatically.** `/loop-resume` first reconciles, read-only: + +- actual Git state (branch, HEAD, dirty paths) vs the recorded checkpoint; +- recorded evidence paths vs reality; +- interrupted changes found on disk (present but unrecorded). + +A **potentially interrupted stage** — claims that cannot be reconciled, or +uncommitted work the checkpoint does not explain — sets the run to +`RECOVERY_REQUIRED`: the resume reports the discrepancy, the run stays halted, +and modifications proceed only after the operator inspects the findings and +explicitly instructs continuation. Recovery with a dirty reconciliation +report is an accepted, expected outcome — not a failure of the protocol. + +**No promise of bounded data loss.** The earlier draft's +"at-most-one-stage loss" claim is *withdrawn*: the checkpoint records intent, +not guarantees; a killed stage may lose arbitrary in-flight work.
