Attempt 2

Back to durable goal · Attempt history

Targeted failure

Attempt 1’s repo_context_search cannot execute when ripgrep is unavailable from the runtime PATH, preventing all starter packages from passing their portable Bazel execution test.

Hypothesis

Keeping ripgrep as the preferred engine but falling back on a bounded Node filesystem search will preserve normal-machine speed and make the reusable package functional in hermetic or minimal environments.

Exact inputs and plan

  • Parent candidate: c9300c9887104777c8915e3d4f390196604e9bd18497bbec319415d1a4ad057f
  • Preserve all runtime, storage, MCP, and other starter-package code.
  • Add a bounded fallback with workspace path checks, file/byte/result limits, fixed or regex matching, context lines, and basic glob filtering.
  • Store it as a new immutable repo_context version; retain Attempt 1’s source version in its manifest history.
  • Rerun the starter test first, then the complete focused package checks.

Planned review packet

  • Search succeeds without rg in Bazel’s test PATH.
  • Traversal outside the workspace remains rejected.
  • All eight starter tools execute through loaded Cordis Fibers.
  • Previously passing lifecycle and real stdio checks remain green.

Verdict

Refine. The rebased candidate commit e3e74cb1e573867825347292bf17220a5b9a4a0c fixes criterion 7, but its final integrated regression failed because the lifecycle test used elapsed time to infer that an invocation remained in flight.

Work performed

  • Added a bounded pure-JavaScript fallback as immutable repo_context version fd10633b1569665764e9a526f2cfaf38d1847ee9842934258cefc25f08ea9050 while preserving ripgrep as the preferred engine and retaining the original version in manifest history.
  • Rebased the complete task commit onto fetched remote master 7ad2704cd27757355ab36ec8eb1bb27ef9e1d91d with no conflicts. The resulting tree is 079a0c27b86527c6950cc75b0c8b9dbf572d3e4b.

Verification evidence

  • Pre-rebase bazel_agent bazel test //projects/mcp_cordis:starter_packages_test: pass. All eight tools executed, including search without rg.
  • Post-rebase bazel_agent bazel query //projects/mcp_cordis:all: pass.
  • Post-rebase bazel_agent bazel test //projects/mcp_cordis:all: three of four test targets pass. runtime_test fails at its drain-count assertion with actual 0, expected 1.
  • The test starts a 150 ms invocation, waits only 20 ms, and then starts a new worker before swapping generations. Candidate startup has no upper bound below the old invocation’s delay, so the test does not prove the invocation is still active at the swap.

Acceptance results

  1. Pass in the integrated build test.
  2. Unverified for final acceptance because the lifecycle regression did not complete.
  3. Unverified for final acceptance for the same reason.
  4. Unverified for final acceptance for the same reason.
  5. Pass in the previously focused storage/lifecycle evidence; final rerun is still required.
  6. Pass in the subprocess stdio target; final rerun is still required.
  7. Pass on the exact rebased candidate through the starter-package target.
  8. Pass on the exact rebased candidate through the stdio target.
  9. Fail: the complete fixed regression set is not green.

Progress, approach, and process audit

  • Criterion 7 measurably improved from fail to pass; no starter package now assumes ripgrep is installed.
  • The runtime representation did not regress. The failing value demonstrates that the old request finished before the atomic swap, which is permitted; the test’s elapsed-time setup failed to establish its own precondition.
  • The highest-leverage issue is evidence quality, not another runtime rewrite.
  • Attempt 3 should preserve all delivered runtime bytes and replace only the drain test’s wall-clock inference with a deterministic cross-worker latch.
  • The requested rebase and adapter compilation dominated this cycle’s wall time. Focused query feedback fell to under two seconds once caches were warm.
