Attempt 5

Back to durable goal · Attempt history

Targeted failures

Attempt 4 passed every recorded command but independent review disproved four completeness claims: malformed UTF-8 loss was unmarked, built-in consumers silently accepted partial host output, Git status truncation was inferred from capacity rather than omission and missed newline paths, and imported skill evals did not cover their added behavior.

Hypotheses and plan

  1. Have UTF-8 decoding report whether it dropped any retained bytes and OR that fact into truncated; cover malformed output below and above the cap.
  2. Publish new immutable versions for each reusable package whose result fields need host-truncation propagation. Preserve every previously tracked version byte-for-byte and make partial fields explicit rather than hiding signal termination as ordinary success.
  3. Parse status records before deciding whether an additional logical change was omitted, capture NUL-delimited paths with newline-safe expressions, and cover exact-one, max-two, max-one-of-two, copy, and newline cases.
  4. Add offline cases that exercise compatible multi-target Bazel batching, immutable exact-hash candidate promotion/regression, and durable task-owned push behavior that excludes disposable output and reports blockers.
  5. Track disposal of an activation removed by #handleUnavailable() as a retirement so shutdown cannot return before its worker teardown completes.
  6. Rerun each focused target, all affected package/skill tests and builds, Buildifier, and another independent review before freezing a commit.

Boundaries

  • Retain the Cordis/worker/storage architecture and the shutdown correction.
  • Do not modify historical hash-named version bytes.
  • Do not import any PR 24 path outside projects/agents.
  • Do not add live, billable eval targets; these cases extend the existing offline-validated behavioral configurations.
  • Do not prepare, commit, or publish until the new review is clean.

Planned acceptance packet

  • Every discarded output byte makes truncated true.
  • Each Git/context field that can be partial exposes that fact; bounded diff and search remain successful.
  • Shutdown joins teardown for generations that become unavailable immediately before shutdown, not only those still present in the active map.
  • Exactly maximum status changes reports complete, while an actual additional parseable change reports truncated; valid newline paths round-trip.
  • Eval configs validate with cases for every material imported behavior.
  • A second independent read-only review reports no remaining actionable issue.

Working-tree result

  • ctx.exec() now retains a combined bounded prefix, marks byte overflow and malformed UTF-8 loss as truncated, and stops the child before resolving.
  • repo_context activates immutable version abd0db3e...; root, HEAD, status, and ripgrep results propagate host truncation explicitly.
  • git_worktree retains original version 70d8f28d... unchanged and activates sole new version 8853aa20.... The rejected intermediate de978... file is absent. Exact-limit status, newline paths, incomplete NUL records, revision discovery, history, name-status, diff, and aggregate flags are covered.
  • Runtime shutdown is memoized, closes admission, joins admitted package operations, and tracks disposal after an unavailable activation leaves the active map.
  • PR 24’s projects/agents subtree is integrated as bazel-agent, goal, and packaged decision-review changes only. Newer goal-record and delegation policy is preserved; added eval cases exercise every material imported rule.

Validation evidence

  • Focused Bazel regression/eval batch: 8 of 8 tests pass.
  • Entire affected MCP package plus skill evals: 12 of 12 tests pass.
  • Entire MCP package and all three skill libraries build; every skill validation aspect passes.
  • Root //:buildifier_test: 1 of 1 passes.
  • git diff --check, JavaScript syntax checks, and every retained/new reusable package content hash pass.

Progress, approach, and process audit

Attempt 5 materially closes every falsified completeness claim from Attempt 4 without replacing the accepted architecture. New versions are confined to the two reusable packages whose public result contract changed; historical bytes remain intact. The test packet now observes semantic completeness rather than only byte caps or array lengths. The remaining critical path is review and exact-candidate delivery, not additional implementation.

Verdict: proceed to independent review. Do not freeze or publish the candidate until that review is clean.

Independent-review correction 1

The agent-skill review found that PR 24’s absolute “commit and push every turn” wording contradicted the preserved throwaway-record policy when a rejected attempt leaves no durable tracked change. The merged skill now makes delivery conditional on authorized, nonempty durable tracked progress and explicitly forbids empty/cosmetic commits or promoting disposable out/ evidence merely to manufacture a checkpoint. A new offline case covers the no-durable-output rejection. This changes the candidate and invalidates the prior goal eval result; rerun the affected skill and integrated gates after the remaining reviewers report.

The follow-up review also found that the durable-progress eval incorrectly required preparation while remote-ref ownership was unknown. Its oracle now requires exact inspection followed by a safe stop before preparation, rewrite, or publication until ownership is established.

The review then found that decision-review’s self-contained case could run meaningfully with the available provider, so offline validation alone did not satisfy current skill-package policy. A manual, credentialed promptfoo_test target now complements the ordinary offline validation target; it is declared but will not be executed as part of normal or delivery validation.

The generic goal skill also carried Blender-specific scene, topology, datablock, and linked-library mechanics from PR 24. Those details could misroute domain policy into software and documentation goals. The merged text now retains only the cross-domain invariant: immutable candidate copies, one writer per candidate, exact or deterministic component promotion, and post-promotion regression. Its eval uses a generic protected deliverable. The bazel-agent eval documentation now correctly describes its plural cases.

The generalized component-promotion rule initially tried to compare a component-merged aggregate with a whole-candidate hash, which is impossible. It now distinguishes exact whole-candidate promotion from independently hashed component promotion and always reruns affected aggregate gates.

The first manual decision-review target reused credentials without isolating subject and judge state. Its config now uses separate runner-provided Codex homes and workspaces, an explicit executable override, and isolated proxy inheritance; its README documents the required absolute-path invocation.
