Acceptance criteria

Back to durable goal

1. projects/mcp_cordis is a documented, Bazel-built standalone MCP stdio server and is not coupled to a Codex plugin manifest.
2. The server demonstrably uses Cordis lifecycle primitives rather than a separately invented plugin framework.
3. One connected MCP client can define, start, inspect, invoke, update, stop, and remove a runtime package without restarting the server.
4. MCP source writes are syntax-checked and atomically persisted. Existing running entries are handed to Cordis HMR without a private acknowledgement protocol. The MCP does not promise synchronous activation, broad activation rollback, or restoration of prior on-disk bytes. Native Cordis failure behavior remains intact. The pinned HMR dependency serializes reload work and drains later observed writes so an in-flight replacement cannot discard the latest persisted source. Git owns reusable source history; the runtime does not invent a second version store.
5. Reusable package source is stored beneath projects/mcp_cordis/plugins; disposable source and configuration resolve beneath the current workspace’s out/mcp_cordis.
6. Reusable packages reload after an MCP server restart. Disposable packages have an explicit promotion path into the reusable library.
7. At least three useful, non-sensitive starter packages are justified by recurring prior-session tasks and have executable tests.
8. Stable gateway tools allow immediate invocation even if a particular MCP client does not refresh dynamically registered schemas.
9. Focused tests, builds, repository formatting checks, and an end-to-end MCP transcript pass for the exact delivered candidate.
10. On Linux, ctx.exec() results, execution timeouts, and plugin disposal settle only after the direct child and live members of its original process group stop. A trusted package that deliberately creates a new session is explicitly outside that guarantee; unsupported platforms fail closed. cordis_invoke.timeout_ms is a response deadline, not handler cancellation; the admitted handler retains its Fiber lease until completion.
11. Trusted Codex sessions discover the MCP from the checked-in .codex/config.toml in the active clone or linked worktree. Server startup releases Bazel’s output-base lock before serving stdio, and source plus disposable state remain scoped to that worktree.

Evidence plan

• Unit tests cover validation, standard Cordis entries, lifecycle disposal, persistence roots, eventual reload, and promotion.
• An MCP integration test drives initialize/list/define/run/invoke/update/stop over stdio without restarting the process.
• A restart test proves reusable package recovery.
• Package tests execute every starter package through the same runtime path.
• Process regressions cover normal results, output limits, valid UTF-8 prefix retention, timeout, disposal, and rejection of launches after disposal.
• HMR regressions write a second generation during slow top-level evaluation and slow asynchronous activation, then require convergence to the latest persisted generation.
• Bazel query, test, build, Buildifier, and git diff --check cover repository integration.
• A launcher probe starts the generated-script MCP and runs a second Bazel command concurrently in the same linked worktree.

Fixed regression set

• git diff --check
• Focused //projects/mcp_cordis:all Bazel tests and build
• //:buildifier_test after every BUILD or Bzlmod change
• End-to-end stdio lifecycle and restart tests

Attempt 1

Back to durable goal · Attempt history

Hypothesis

A small adapter around @deepseek-ai/cordis@4.0.1 can provide durable, transactional runtime packages behind a fixed MCP stdio surface without embedding DeepSeek Harness or restarting the MCP connection.

Exact inputs

• Parent checkpoint: task-start state of branch t3code/runtime-modifiable-plugin
• Cordis: @deepseek-ai/cordis@4.0.1
• MCP server/client: @modelcontextprotocol/server@2.0.0 and @modelcontextprotocol/client@2.0.0
• Node: repository-pinned Node 24.13.0
• Package source contract: one import-free JavaScript expression returning a Cordis plugin with apply(ctx)

Candidate plan

1. Add an ordinary Bazel package with a dedicated exact pnpm lock.
2. Persist definitions as content-addressed immutable source plus atomic manifests under explicit project and scratch roots.
3. Evaluate each generation in a worker, mount it through a real Cordis Context and Fiber, and register handlers through Cordis effects.
4. Activate transactionally: prove the candidate ready, swap the active pointer, drain in-flight calls, then dispose the prior Fiber exactly once.
5. Expose fixed MCP tools for list, inspect, define, run/reload, invoke, stop, remove, and promote; never rely on dynamic MCP schema refresh.
6. Seed and execute repo_context, git_worktree, and network_probe through the same runtime path.

Review packet

• Explicit (scope, name) identities prevent hidden scratch/project shadowing.
• Workspace root is an explicit CLI argument or BUILD_WORKSPACE_DIRECTORY, never inferred from a runfiles cwd.
• A failed candidate never changes the active manifest or runtime pointer.
• Package stdout/stderr cannot corrupt MCP stdout.
• Disposable state remains under ignored out/mcp_cordis; reusable source is public project code.

Verdict

Refine. Candidate c9300c9887104777c8915e3d4f390196604e9bd18497bbec319415d1a4ad057f proved the architecture but failed acceptance criterion 7.

Work performed

• Added the exact pnpm/Bzlmod/Bazel package and documentation.
• Implemented content-addressed storage, worker-isolated Cordis Fibers, transactional generation replacement, fixed MCP gateways, and stdio entry.
• Added project and scratch scopes, promotion, recovery, and three starter package definitions.
• Added lifecycle, in-memory MCP, subprocess stdio, and package execution tests.

Verification evidence

• bazel_agent bazel query //projects/mcp_cordis:all: pass after the pnpm v10 declaration and starter catalog were present.
• bazel_agent bazel test //projects/mcp_cordis:runtime_test: pass. This covers real Cordis contexts/effects, immutable versions, rollback, drain, scopes, promotion, restart, removal, isolation, and fixed MCP invocation.
• bazel_agent bazel test //projects/mcp_cordis:stdio_test: pass. One stdio client hot-updated v1 to v2 without a process change; a new server process recovered the project package.
• bazel_agent bazel test //projects/mcp_cordis:starter_packages_test: fail because repo_context_search received spawn rg ENOENT in the hermetic test PATH.

Acceptance results

1. Pass: documented standalone stdio server built and exercised by Bazel.
2. Pass: source and runtime tests use Cordis Context, Fiber await/dispose, and effect cleanup.
3. Pass for implemented lifecycle operations; fixed MCP use is proven on one connection.
4. Pass: content hashes, failed syntax/startup rollback, and v1/v2/v3 behavior are exercised.
5. Pass: roots and exact scope identity are exercised in isolated workspaces.
6. Pass: promotion and server-only project recovery are exercised.
7. Fail: the Git and network package paths were not reached after the repository search package required an unavailable rg executable.
8. Pass: in-memory and real stdio tests invoke new handlers through the stable gateway without reconnecting.
9. Unverified: the full integrated fixed regression set has not run.

Progress, approach, and process audit

• Criteria 1–6 and 8 improved from unverified to measured passes. Criterion 7 is an absolute portability failure, not merely a weaker result.
• Passing lifecycle and stdio tests support retaining the direct Cordis, worker, storage, and fixed-gateway representation.
• The highest-leverage problem is removing the starter package’s undeclared executable assumption while retaining ripgrep as a fast path.
• Continue the architecture but revise repo_context_search; no evidence supports discarding the runtime foundation.
• The largest avoidable delay was 144 seconds in a failed test whose worker was not registered for unconditional teardown. node:test cleanup now registers before assertions, reducing the next failure cycle to under a second.
• The next feedback loop starts with the single starter target and only then returns to the integrated regression set.

3.2 -

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.

Attempt 3

Back to durable goal · Attempt history

Targeted failure

The integrated lifecycle test assumes that a 150 ms invocation remains active after a new worker has started. Under parallel Bazel execution, the candidate can become ready only after that invocation has completed, making the expected drain count nondeterministic.

Hypothesis

A file-backed started/release handshake in the test package will establish the in-flight precondition independently of worker startup speed and prove that a generation swap reports and drains exactly one old invocation.

Exact inputs and plan

• Parent commit: e3e74cb1e573867825347292bf17220a5b9a4a0c
• Parent tree: 079a0c27b86527c6950cc75b0c8b9dbf572d3e4b
• Base commit: 7ad2704cd27757355ab36ec8eb1bb27ef9e1d91d
• Preserve all product runtime, storage, MCP, package, and build files.
• Extend only the lifecycle test fixture with optional started/release paths.
• Wait for the started marker before activation, keep the old handler blocked until after the drain count is observed, and release it in finally so a failed assertion cannot strand teardown.
• Rerun the focused lifecycle target first, then the entire recorded regression set on one amended candidate.

Planned review packet

• The test contains no fixed request duration or startup race.
• Replacement reports exactly one draining call.
• The old call returns v2 and the next call returns v3.
• Cordis cleanup still runs exactly once.
• All project, buildifier, and diff checks pass on the same commit tree.

Verdict

Accept as the final local candidate. Commit 7cfef0719075ad372c3bb257ad216b35770356b2 and tree 34153eca0f582af5c641f81bf8c7209b0045ab9a pass the entire evidence plan. Remote delivery is pending separate authorization.

Work performed

• Replaced the 150 ms elapsed-time assumption with workspace-local started and release markers in the lifecycle test fixture.
• Proved the new v3 generation serves calls while the old v2 invocation remains blocked, then released v2 and proved its Cordis effect disposes exactly once.
• Applied Buildifier’s mechanical label ordering to the runtime test data.
• Amended the sole feature commit through the delivery adapter without changing its direct base parent.

Verification evidence

• git diff --check HEAD^..HEAD: pass on the prepared commit.
• bazel_agent bazel query //projects/mcp_cordis:all: pass.
• bazel_agent bazel test //projects/mcp_cordis:runtime_test: pass after the deterministic gate.
• bazel_agent bazel test //projects/mcp_cordis:all --nocache_test_results: pass, four of four tests executed on the exact commit.
• bazel_agent bazel build //projects/mcp_cordis:all: pass, all nine targets.
• bazel_agent bazel test //:buildifier_test --nocache_test_results: pass.
• The delivery receipt records direct base 7ad2704cd27757355ab36ec8eb1bb27ef9e1d91d, prepared head 7cfef071, and prepared tree 34153eca.

Acceptance results

1. Pass: documented standalone Bazel-built stdio MCP server.
2. Pass: lifecycle tests exercise real Cordis contexts, Fibers, and effects.
3. Pass: one runtime and one stdio connection exercise the complete mutable package lifecycle.
4. Pass: immutable versions, rollback, deterministic drain, and exact cleanup are exercised.
5. Pass: isolated project and scratch roots are exercised.
6. Pass: promotion and subprocess restart recovery are exercised.
7. Pass: three justified starter packages and all eight tools execute.
8. Pass: fixed discovery/invocation gateways work without reconnecting.
9. Pass locally: all recorded checks and the real stdio transcript pass on the exact candidate tree. Remote repository handoff remains pending authority.

Progress, approach, and process audit

• Criterion 9 improved from a nondeterministic failure to a forced, exact-tree pass; no technical criterion regressed.
• The explicit gate improves evidence in absolute terms: candidate startup can take arbitrarily longer than the old call without changing the assertion.
• Independent code review and the measured zero drain count both supported retaining transactional start-before-swap behavior.
• No defect survived two attempts. The elapsed-time test and Buildifier order are resolved in their first corrective cycle.
• Adapter and root Buildifier startup dominated wall time; warmed focused tests remained under ten seconds. Further local optimization would not change the delivery critical path.
• The only remaining action is remote publication, which cannot proceed from a rebase-only authorization.

Attempt 4

Back to durable goal · Attempt history

Targeted failures and scope

PR 32 commit 7cfef071 is remotely reproducible but is not a final candidate: three review findings are valid. The user also requires the four projects/agents changes from PR 24, whose missing decision-review package explains the current base’s dangling instruction reference.

Hypotheses

1. Applying PR 24’s changes three-way will preserve newer goal guidance while importing its result-first additions, Bazel batching guidance, and decision-review package.
2. Treating command overflow as bounded success will preserve useful prefixes for search and diff consumers without leaking child processes or invalid UTF-8.
3. Enforcing max_changes before every porcelain status record will bound all record kinds uniformly.
4. Closing admission, draining registered package locks, then disposing active workers will make shutdown linearizable with concurrent run/reload.

Exact inputs and boundaries

• Current and published task commit: 7cfef0719075ad372c3bb257ad216b35770356b2.
• Current base/direct parent: 7ad2704cd27757355ab36ec8eb1bb27ef9e1d91d.
• PR 24 base/head: ada3ed90123c224729f9174c6127c50b933d2f48 / da2085f1807bfea1c7f3979730f6b7df0033fdce.
• Import boundary: only paths beneath projects/agents changed by PR 24.
• Review boundary: the three existing PR 32 threads and directly required regression coverage; no unrelated runtime redesign.
• Preserve all immutable package versions already referenced by manifests.

Candidate plan

1. Merge the PR 24 bazel-agent and goal hunks into current files; add decision-review plus the offline eval structure required today.
2. Add black-box execution overflow coverage and implement bounded UTF-8-safe truncation while preserving timeout/spawn errors.
3. Add table-driven status-limit coverage and publish a new immutable git_worktree version with the limit check before record parsing.
4. Add a deterministic concurrent activation/shutdown gate and memoized shutdown sequence that waits for admitted locks before disposal.
5. Run focused tests first, then both affected packages, Buildifier, exact diff checks, delivery preparation, exact-candidate validation, publication, and review-thread replies/resolution.

Planned acceptance packet

• PR 24 provenance maps exactly to the imported agent changes; newer main guidance remains present.
• decision-review validates and its Promptfoo configuration loads offline.
• Output at and beyond the cap is bounded, UTF-8 valid, truncation-marked, and stopped; under-cap and timeout behavior remain correct.
• Every porcelain-v2 record kind obeys max_changes.
• Shutdown cannot resolve before an already-admitted activation is owned and disposed, and later calls reject runtime_closed.
• All previous MCP lifecycle, restart, package, and stdio regressions remain green on the exact delivered commit.

Progress, approach, and process audit

• Remote publication improved delivery evidence but exposed three absolute correctness failures; validation success alone was insufficient.
• The PR 24 request resolves an upstream packaging inconsistency and is independent enough to integrate before runtime corrections.
• The current representation remains viable: every defect has a narrow controlling mechanism and deterministic test. No evidence supports replacing Cordis, the worker boundary, or content-addressed persistence.

Work performed

• Imported all four PR 24 agent-tree changes three-way and added the offline validation files required by current repository policy.
• Changed ctx.exec() overflow from an output-limit rejection to a bounded, UTF-8-valid success result with explicit process-group cleanup and a truncation flag.
• Published the corrected Git parser as new immutable version de978... while retaining 70d8... as permanent rollback history.
• Made shutdown join admitted activation locks before its final active-worker snapshot and added closure checks around initialization storage awaits.
• Added direct regressions plus an actual git_compare cap integration case.

Verification evidence

• Four focused Bazel tests: pass.
• Complete MCP package plus three skill eval-config targets: ten of ten pass.
• Complete MCP package build plus three skill libraries: pass; all skill validation aspects pass.
• Root //:buildifier_test: pass.
• JavaScript syntax, exact new version SHA-256, quick skill validation, and git diff --check: pass.

Final verdict

Refine. The product and packaging gates were green, but independent review found silent output-loss and exact-limit semantics that those gates did not exercise. Preserve the architectural changes; Attempt 5 changes the affected contracts and tests rather than discarding the worker/runtime design.

3.5 -

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.

Attempt 6

Back to durable goal · Attempt history

Why Attempt 5 was rejected

Attempt 5 passed every repository gate, but the required second independent review found release-blocking lifecycle and compatibility defects: worker termination could orphan detached ctx.exec() children, promotion was outside shutdown admission, unavailable candidates could cross the persistence/swap boundary, and the new always-partial output contract made retained package versions lie about completeness. The same review found narrower package and imported-skill correctness gaps. The candidate is rejected despite green tests.

Strategy reset

1. Preserve backward compatibility by making partial output an explicit ctx.exec() option. Existing package versions retain rejection on overflow; new versions opt in and receive an explicit output-limit reason alongside truncated.
2. Close worker disposal admission before spawning, clean child process groups both before and after admitted handlers settle, and replace immediate parent termination with graceful disposal followed by the existing bounded forced fallback.
3. Track complete promotion operations in the runtime admission barrier and stage candidate availability across persistence so a failed candidate cannot replace or persist over the working generation.
4. Publish sole new immutable starter versions after correcting unexpected signal/error handling, exact-boundary flags, omitted-record flags, Git read-only behavior, robust history framing, and containment checks. Delete every rejected untracked hash candidate rather than retaining it as history.
5. Pin LF checkout semantics for hash-addressed source and test retained-version compatibility, exact output boundaries, outer timeouts, settlement-after- group-confirmed settlement, late-spawn disposal, promotion shutdown, and candidate failure.
6. Finish the PR 24 merge by keeping generic goal invariants generic and making the manual decision-review eval isolate subject and judge state.

Boundaries

• Do not change any previously tracked hash-named source bytes.
• Do not add PR 24 paths outside projects/agents.
• Do not run the credentialed manual Promptfoo target.
• Linux is the supported supervised-execution platform for this repository target. The guarantee covers the direct child and live descendants that stay in its original process group; deliberate new sessions are excluded.
• Keep one writer per runtime source group and one writer for all active content-addressed package candidates/manifests.

Acceptance packet

• No live member of a supervised original process group survives inner timeout, outer invocation timeout, disposal, shutdown, or successful truncation settlement.
• Shutdown waits for every admitted mutation, including promotion, and never publishes a candidate observed unavailable during persistence.
• Historical package versions reject overflow under their original contract; only explicit opt-in versions return a marked partial prefix.
• Every result field distinguishes complete, locally clipped, host-limited, failed, and unexpectedly signaled outcomes.
• Exact limits are complete until one additional logical record is observed.
• All content hashes, LF attributes, skill validation, offline eval configs, focused regressions, integrated tests/build, and Buildifier pass.
• A fresh review of the final Attempt 6 diff reports no release-blocking issue.

Work performed

• Restored the historical ctx.exec() contract: overflow and invalid UTF-8 reject by default, while new packages opt into a bounded marked prefix.
• Moved process launch and output accounting from the disposable worker into a parent-owned Linux supervisor. Launch admission is atomic in the parent’s event loop, direct exit terminates the original process group before inherited pipes can hold settlement open, and timeout/disposal results wait for group non-liveness.
• Narrowed the documented contract honestly: a package that deliberately calls setsid() or otherwise creates a new session is outside the trusted original- group guarantee; non-Linux execution fails closed.
• Made shutdown actively dispose both active and draining retired generations, and staged candidate persistence so an unavailable candidate rolls back without displacing the working generation.
• Published one current source candidate per starter package. The hashes are 04b06a7d6277c4a6e8513d970f549ad980a780b68755f28d7b402fe8be26c279 for git_worktree and 94131e058f82328f091613dc68d2717484378066a9c64940d99522c14b48b4d7 for repo_context; historical source bytes remain unchanged.
• Made ripgrep byte-valued JSON fields explicitly incomplete rather than returning empty text under a false completeness claim.
• Imported PR 24’s agent skills, added current validation/eval packaging, generalized goal policy, and moved this complete goal directory into the reusable project docs hierarchy.

Verification so far

• Static syntax, manifest/hash, LF-attribute, local-link, and git diff --check checks pass on the corrected working tree.
• Focused process, unavailable-shutdown, and retired-generation tests pass 3/3 in Bazel invocation 9b1b2d34-8490-474a-b12c-e2052bf2d90b.
• Process, package-byte-field, and retired-generation tests pass 3/3 in Bazel invocation 7c680be8-e2a6-4b5b-9b45-4a0390f39a5a.
• The earlier 14/14 integrated packet, complete affected build, validation aspects, and Buildifier passed before the supervisor and final package-byte corrections. Those results are preserved as progress evidence but are invalidated for final acceptance and must be rerun.

Independent-review result

The first final review rejected the candidate despite green tests. It found that outer timeouts settled before cleanup, a signal was mislabeled as reaping, the shared PID publication window made disposal unbounded, inherited pipes could delay successful commands, retired generations were not actively disposed by shutdown, ripgrep byte fields could masquerade as text, and the durable records were stale. The strategy changed from worker-side process ownership to parent-owned supervision; every other finding has a direct source or regression correction. Fresh review of that new strategy is pending.

Acceptance status

• Criteria 1-8: pass on implementation and existing executable evidence.
• Criterion 9: unverified after the latest source changes; full exact-candidate validation and delivery remain.
• Criterion 10: focused regressions pass; fresh adversarial source review is still pending.

Progress, approach, and process audit

Attempt 6 improved compatibility, package completeness, promotion admission, and teardown coverage in absolute terms. The repeated late lifecycle findings showed that PID publication inside a terminable worker was the wrong ownership boundary, not merely an under-tested implementation. Moving execution to the parent removes that race and makes cleanup ordering directly observable. The highest-leverage remaining work is review and full validation of this new boundary, not more feature expansion. The attempt remains open until that review accepts one frozen candidate and delivery verifies the same bytes.

Decision

Refine within Attempt 6: the review changed an implementation strategy without changing the recorded goal or acceptance contract. Do not freeze or deliver until fresh review and the complete invalidated regression set pass.

Attempt 7

Back to durable goal · Attempt history

Why Attempt 6 was rejected

The user correctly identified that each package’s manifest.json, content-addressed versions/ directory, and active/latest pointers were a custom package manager rather than an MCP or Cordis standard. That mechanism made reusable source look temporary, duplicated Cordis loader responsibilities, and drove much of the worker-generation complexity. Green tests cannot justify shipping the wrong extension model.

Decision review

Verdict: revise and proceed. The published DeepSeek Cordis packages provide the missing standard mechanisms directly:

• @deepseek-ai/cordis-plugin-loader owns runtime entries and lifecycle;
• @deepseek-ai/cordis-plugin-include persists entries in cordis.yaml and transactionally refreshes them with rollback; and
• @deepseek-ai/cordis-plugin-hmr watches normal modules, imports changed code before replacement, and restores the prior runtime when reload fails.

The strongest objection is that HMR is event-driven and failed source reloads are logged rather than returned to the file writer. MCP-driven updates must therefore retain prior bytes, wait for a correlated reload result, and restore the prior source on failure or timeout. Manual external edits retain Cordis HMR’s normal behavior and diagnostics.

Frozen plan

1. Pin the exact released Loader, Include, HMR, Timer, and required peer dependencies through the project-owned npm lock.
2. Replace package manifests and hash-named versions with normal ESM modules: reusable modules under projects/mcp_cordis/plugins/, disposable modules under out/mcp_cordis/plugins/.
3. Make projects/mcp_cordis/cordis.yaml and out/mcp_cordis/cordis.yaml the authoritative standard entry lists.
4. Mount the official Cordis Loader, two Include trees, Timer, and HMR in the stdio server. Keep the stable MCP gateway, workspace helpers, bounded process execution, and tool-registration effects as host services.
5. Implement MCP define, update, start, stop, remove, and promotion as atomic source/config changes followed by Cordis lifecycle acknowledgement and rollback. Use Git for reusable history; do not create a second version database.
6. Replace version-store tests with standard-config, restart, HMR rollback, manual-edit reload, and project/scratch promotion tests.
7. Run the complete affected test/build/Buildifier packet, obtain a fresh independent review of the standard design, then rebase and deliver PR 32.

Boundaries

• Do not add an MCP Registry server.json unless the server is actually being prepared for registry publication; it describes the whole server, not its internal Cordis entries.
• Do not retain committed hash-named source snapshots or custom package manifests.
• Keep reusable source and config in the project and all disposable modules, atomic-write scratch, state, and logs under out/mcp_cordis.
• Keep one normal module per package and one stable entry id per scope.
• Preserve PR 24’s scoped projects/agents import and the accepted process execution corrections that remain relevant to the in-process host.

Acceptance status

Implementation and working-tree validation are complete; exact post-rebase delivery gates remain open. The final architecture adds four narrow host guards around the official Cordis services: synchronous activation admission to prevent a never-settling apply(), source-token HMR correlation, a private stdio protocol stream, and Fiber/invocation-owned Linux process supervision. The real stdio regression covers define, inspect, run, invoke, update, failed update rollback, stop, remove, logging isolation, and restart recovery.

Bazel invocation 39711671-375a-413f-8a72-e6f9ff892bd3 passes all 11 affected tests on the rebased implementation after the import-boundary review corrections, including Buildifier and all three imported skill configurations. Invocation 153467fd-e62d-4eab-b260-6754d17fe8e2 builds all 26 affected targets. Those receipts bind implementation commit 0a93e487; the following amendments change only this durable goal record, with proportional diff and format validation required before publication. Fresh independent review accepted durable-record commit c05bd45a with no actionable findings. PR 32 was republished at the verified rebased head, its obsolete description was replaced, and all three prior review threads were resolved.

Attempt 8

Back to durable goal · Attempt history

Trigger

The fresh hosted review of the delivered standard-Cordis candidate found three valid starter-package defects: the JavaScript search fallback recursively read ignored and hidden files when ripgrep was absent, fallback submatch offsets used UTF-16 code units instead of ripgrep-compatible UTF-8 bytes, and a bounded textual HTTP body could end with a replacement character when the byte limit split a multibyte sequence.

Corrections

• The JavaScript fallback now fails closed for directory searches and supports only explicitly selected files. This preserves hermetic single-file fallback without silently weakening ripgrep’s hidden and ignore filtering.
• Fixed-string and regular-expression fallback matches calculate start and end from UTF-8 byte lengths.
• Textual HTTP previews discard only an incomplete trailing UTF-8 sequence; the raw retained-byte count and truncation signal remain exact.
• Follow-up review found that case-insensitive fixed matching could still use a length-changing lowercased index, explicit files did not override globs as they do in ripgrep, and unfiltered listing reparsed a malformed scope instead of returning the healthy scope with an error.
• Case-insensitive fixed fallback now matches against the original line with a Unicode regular expression, explicit files bypass fallback glob filtering, and unfiltered listing returns per-scope errors alongside healthy packages. Explicitly listing a malformed scope continues to fail directly.
• Final hosted review showed that a valid config with an unavailable module still bypassed the malformed-config catch, and bounded reads reported the requested range end instead of the last retained line. Unfiltered listing now skips every scope whose Include failed to mount, and bounded reads derive endLine from retained content.
• Fresh diff-focused correctness scrutiny then found that repeated initialize() calls lost the original partial-startup errors. The runtime now preserves and clones those errors across idempotent initialization.
• The same scrutiny found that incomplete UTF-8 suffix removal also ran for a naturally completed malformed textual body. It now runs only when the local byte cap truncates the response; naturally malformed bytes retain the prior replacement-character preview.
• The repository’s repo-delivery skill now invalidates prior correctness verdicts after behavior-changing edits and requires proportional adversarial scrutiny in addition to test reruns.
• Exact-thread reconciliation after the final hosted review exposed one older unresolved finding and one new finding: the explicit-file regex fallback matched UTF-16 surrogate halves, and cordis_define plus cordis_promote advertised overwriting operations as non-destructive. Regex fallback now uses Unicode scalar mode, and both source-overwriting tools carry the destructive MCP hint.
• The next exact-commit review found two more fallback-boundary defects: adjacent matches were also emitted as context, and a retained empty line was reported like a request past EOF. Fallback search now plans a single ordered event stream from all matching lines, and bounded reads track range existence independently from textual content.

Evidence

• Focused invocation b73ce3b4-bfb6-4081-b84f-29c3f763b3a4 passes both corrected starter-package test targets.
• Complete MCP test invocation 93845f08-cd10-4dfb-88c5-034497dea58a passes all 7 tests; build invocation d7716a48-9509-44fe-9e37-b5c44904fffd builds all 16 targets.
• Buildifier invocation 1fb561cc-d336-49db-813f-de26b7fedbe4 passes.
• Regression cases prove directory fallback fails closed while an explicitly selected hidden file remains available, both fallback engines report byte offsets for éneedle, and a one-byte preview of é returns an empty valid UTF-8 prefix rather than U+FFFD.
• Follow-up focused invocation c07704be-cdf8-4045-a0c0-4626ebc0d1e7 passes both affected targets. Complete test invocation 3fbaa4e1-8ea1-4b3f-a533-51e1ad01f87b passes all 7 tests, build invocation f87e45b6-765e-49c8-a618-cd2eb1efa1ad builds all 16 targets, and Buildifier invocation 8542838d-92ae-4999-b1e8-fac631629f6f passes.
• Final-cycle focused invocation 99866999-c31d-457f-b64b-c7a15073e7a2 passes both affected MCP tests. Combined affected invocation e86a5d1c-cadf-4ff6-9647-3e1050e461e6 passes all 8 MCP and skill tests; 083fbf55-851e-4db4-b8e5-e5871c874faa builds all 19 affected targets. Skill quick validation and Buildifier both pass.
• Focused starter invocation e80439df-bddd-4a76-b9e1-be6c7f1ed649 distinguishes a cap-split multibyte prefix from a naturally completed malformed textual body.
• Exact aggregate validation exposed timing-sensitive evidence: a wall-clock admission bound failed under load, and the expected invocation timeout could reject before its assertion was attached. The test now asserts the wrapped synchronous-admission semantics and attaches the expected rejection before waiting for its PID fixture. Invocation e7d69598-b843-4da4-833b-e024d406b8ca passes three consecutive runs.
• A later loaded aggregate run exposed a real HMR rollback race. Cordis restores the prior module cache after a failed import without emitting a reload event; the host unnecessarily waited for a second filesystem reload that could be absent. Rollback now accepts the already-restored prior source marker and waits for HMR only when the failed candidate actually reached the cache. Invocation 5f9b49e0-d3d3-4f9e-84ec-602dfbe38c77 passes three runs.
• Focused invocation 132e2f33-837c-40b2-83b5-4b06ceadfd0f passes the Unicode fallback and real-stdio MCP annotation regressions.
• Complete affected invocation b19d303e-0aca-4097-a191-e81015dc2982 passes all 8 MCP and skill tests; build invocation 1c8aa274-dd72-4e6f-9491-de5e283b2c5c builds all 19 targets, and Buildifier invocation 34f6f5c7-7f44-478b-b939-63ac03c3bbb1 passes.
• Focused invocation 2528b6ee-7d82-48c9-a607-298a4cef0b9b proves adjacent matches remain ordered match events and empty retained lines report their actual endpoint while a request past EOF reports null.

Verdict

Accept locally. Publish the exact follow-up correction commit, resolve the hosted review threads, and verify the remote head before final handoff.

Attempt 9

Back to durable goal · Attempt history

Trigger

The user rejected the growing HMR race-handling layer and explicitly requested the simplest robust way for an MCP server to load DeepSeek/Cordis plugins. The published parent is bc4e5ae97ef9ea968c01b1b2a55403ae032a6a8d. An unpublished polling experiment is rejected rather than promoted.

Hypothesis

Atomic persistence plus the official Cordis Include and HMR services is the smallest reliable boundary. If MCP source mutations stop claiming synchronous activation or transactional on-disk rollback, the runtime can delete its source-marker protocol and every dependency on Loader internals while still loading, invoking, and eventually hot-reloading normal Cordis plugins without restarting the MCP connection.

Frozen plan

1. Keep standard cordis.yaml, ordinary plugins/*.mjs, and the two project and out/mcp_cordis scopes.
2. Keep the fixed MCP list/invoke gateway and the existing package context API.
3. Validate module syntax before an MCP write and use atomic file replacement.
4. For an existing running module, return after persistence with persisted: true, sourceChanged: true, and activation: "pending"; official Cordis HMR owns eventual activation. Do not claim that every evaluation or apply() failure restores the prior live entry.
5. Keep public Include refresh for entry-list changes, because it is the official transactional API for starting, stopping, adding, and removing entries.
6. Delete injected source markers, HMR acknowledgement waiters, polling, Loader loadCache inspection, and MCP-owned source rollback.
7. Update documentation and tests so success means persisted/configured, while live update is verified by bounded eventual observation.
8. Retain and validate the two pending repo_context review corrections for ordered context events and empty-line endpoints.
9. Register the server in the trusted workspace’s .codex/config.toml. Use a worktree-resolving launcher and Bazel’s run --script_path handoff so the long-lived MCP does not retain the Bazel output-base lock.
10. Rebase onto d29f9d471ea467e8dfc75db4eedeedbbae43dc2d, preserve its projects/goal redesign, and discard the superseded in-place goal-skill edits rather than replaying them.

Planned review packet

• Focused runtime, stdio, and repo_context tests.
• Complete //projects/mcp_cordis:all tests and build.
• repo-delivery skill tests and root Buildifier.
• Fresh diff-focused scrutiny of update failure, disabled-entry, promotion, restart, shutdown, and watcher timing paths.
• Independent review and exact PR 32 thread reconciliation before delivery.

Current verdict

Refine. Removing wrapper-side acknowledgement machinery was correct, but an independent reproduction proved that unmodified HMR 1.0.16 can lose a source change arriving during an in-flight reload. Attempt 10 keeps the thin wrapper and moves serialization into a focused, reproducibly pinned dependency patch. The separate delivery-adapter refusal still prevents the history rewrite.

3.10 -

Attempt 10

Back to durable goal · Attempt history

Trigger

Independent review of Attempt 9 reproduced a lost update in pinned @deepseek-ai/cordis-plugin-hmr 1.0.16. A slow top-level-await replacement followed by a second source write left the latest bytes on disk while the earlier generation remained live. The public HMR surface has no module-failure event, so a wrapper-side single-flight gate cannot be both safe and recoverable.

Hypothesis

The narrowest robust correction belongs in HMR’s own reload scheduler. A standard pnpm dependency patch can serialize partialReload() calls, snapshot each observed change set, and drain changes arriving during an in-flight reload. mcp_cordis then remains a thin persistence and invocation gateway without source markers, Loader-cache inspection, polling, or acknowledgement state.

Frozen plan

1. Keep the standard Cordis Loader, Include, Timer, and HMR services and normal cordis.yaml plus ESM plugin files.
2. Patch the exact HMR 1.0.16 artifact through pnpm patchedDependencies. Track one module-refresh task, snapshot its stashed URLs before each reload, and drain any URLs observed while that reload is running.
3. Patch both the published JavaScript and TypeScript source shipped in the package; bind the patch through the generated lockfile and Bazel module extension data.
4. Add explicit release-gated overlapping-update regressions for slow top-level module evaluation and slow asynchronous apply() activation.
5. Refresh a disabled entry’s exact cached module through HMR before enabling it, so activation returns only after the latest persisted source is live.
6. Adopt the fetched base’s role-based layout: command files under cmd/mcp_cordis, private implementation under internal, and the separate suite under test.
7. Preserve the two accepted repo_context review corrections and the worktree-local launcher.
8. Stop before Git history mutation until the delivery adapter has an authorized, guarded path for the nine-commit feature range.

Current evidence

• The package registry and upstream repository both expose 1.0.16 as the latest official HMR release; its source still invokes untracked concurrent partialReload() work and clears the shared stash after one successful run.
• git apply --check accepts patches/hmr@1.0.16.patch against the exact resolved package bytes. Its SHA-256 and lockfile patch hash are both ec800d86298faacc86c7717ffa1dce7c28116ab1393b8abc198be6ac02c38489.
• The patch serializes module reloads through complete Cordis Fiber cleanup and activation, drains newly stashed URLs, preserves and retries changes after unexpected scheduler failures, and declares its public refresh API in the shipped TypeScript declarations.
• Bazel invocation ac79a8e4-f5d9-4dd7-a821-29bce3d8ece6 passes the focused runtime suite with explicit top-level-evaluation and asynchronous-apply overlap gates, failed-apply rollback and recovery, manual-edit, and disabled activation regressions.
• Bazel invocation 65c1932a-896b-470d-9462-086dd93beaff passes ten runs each of runtime_test and starter_packages_test.
• Bazel invocations 6490dd57-49e0-4558-b280-f5625db07208, 218e5797-b2d7-44bc-aded-f5df8139ca1c, and 09d4ec2c-aac1-4509-8579-5ef8c5eebe39 pass the complete project tests, complete project build, and root Buildifier check respectively.
• Final independent HMR review accepts the patch identity, stashed-change draining, complete Fiber cleanup join, public declarations, causal overlap tests, rollback and recovery, and disabled-entry activation behavior. Its sole remaining finding was the corrected README publication-order wording.
• The checked-in workspace launcher completed MCP initialization and returned all ten gateway tools while concurrent Bazel query invocation 7739c14e-1b22-40c7-94af-b81143e84d4a completed successfully; SIGINT then produced a clean server shutdown.
• Preliminary current-tree Bazel invocations 95d37231-63f9-44f6-9eee-3f0fe8fb4107, d70f61a2-57e5-4ce9-b8fd-27b06bd02a6d, and 1e186c82-3bcd-4048-a534-fe747e1cf79c pass the complete affected test packet (10/10), affected build packet, and root Buildifier check.
• Guarded delivery inspection found local and remote feature OID bc4e5ae97ef9ea968c01b1b2a55403ae032a6a8d, base OID d29f9d471ea467e8dfc75db4eedeedbbae43dc2d, same-repository PR 32, SSH transport, and nine linear commits all authored and committed by the task bot. Its sole refusal is version 1’s unconditional multi-commit range refusal; the fetched base contains the same limitation and no explicit consolidation authorization.
• The user then explicitly authorized extending the adapter. The new prepare --consolidate <exact-head> path retains every other refusal and requires a single-parent chain, identical author and committer identities, the oldest commit’s ownership marker, unchanged pull-request projection, and signature preservation. It creates one aggregate commit while binding the original remote head into the normal publication receipt.
• Bazel invocations 574dadd5-51b1-443e-b8c2-50ca5d257eb2 and 030a8bb4-2a22-4ece-b632-b3c75572bcee pass the complete adapter suite once, then its Go, skill-validation, and root Buildifier targets three times.
• Independent adapter review found that the first implementation required an extra staged edit and therefore could not consolidate an already-clean range. The corrected gate permits an unchanged index only after exact consolidation evidence; parent-to-tree scope validation still rejects an empty aggregate. A clean --path integration case proves tree preservation and one final commit. Bazel invocation 0d715375-6a8d-4269-ad3e-f8a002888808 passes the corrected suite, and the independent re-review accepts it with no remaining findings.
• Upstream incorporation review preserves the new projects/goal project, drops the deleted predecessor skill under projects/agents, adopts the role-based MCP layout, and adds root-consumer visibility to the branch-owned decision-review skill. The root discovery-link entry must be added after the new base is applied.
• After that visibility correction, Bazel invocations 6099d90d-0ade-43b2-b50b-8f7050c26c32 and 7f4b37a4-b970-46ea-bc76-b4a60aeeab59 pass the focused skill validation and root Buildifier check; git diff --check also passes.

Current verdict

Proceed. The dependency-layer correction addresses the reproduced race and failure recovery at Cordis’s owning lifecycle boundary while the MCP wrapper remains a thin persistence and invocation gateway. The complete local project packet and focused independent review pass. Exact-candidate validation, rebase, publication, and hosted-thread reconciliation remain open.

Attempt 11: exact consolidated rebase

Back to attempt history | Back to durable goal

Objective

Replace the nine task-owned feature commits with one aggregate commit, rebase that exact candidate onto the current remote base, preserve the incoming goal and skill-discovery layouts, and establish publish-ready evidence without bypassing repo_delivery.

Reconciliation

• The fetched base advanced to 63e7b9f0be1e054373415914ff3d2ea2282aa3da and added the reusable projects/goal project, per-skill discovery links, decision-review, and exact-head remote-review waiting rules.
• The old agent-local goal skill remains deleted. The durable MCP goal stays under projects/mcp_cordis/goals/runtime_extensions.
• The branch keeps the upstream root discovery target, including decision-review and projects/goal/skills/goal, and combines the incoming review-waiting policy with the branch’s correctness-revalidation policy.

Delivery adapter corrections

The authorized consolidation path exposed four fail-closed edge cases during the real rebase:

1. Existing PR text must match the requested aggregate projection, rather than the obsolete first commit’s projection.
2. Explicit staging must handle deleted paths, partial directory deletions, and a tracked symlink replaced by a directory.
3. Patch files need the standard repository-wide whitespace exceptions for structural context prefixes.
4. A rebased aggregate path may disappear only when the prior candidate and new base contain the exact same Git tree entry. The receipt then records the reduced path set; added paths, non-identical loss, and an empty aggregate remain refusals.

Each case has focused integration coverage. Every failed preparation restored the original branch, index, and worktree before the next correction.

Exact candidate evidence

• repo_delivery prepare --consolidate produced one commit on the fetched base. The first exact code candidate before the final adapter-and-record update was f1c313b0920cb92f2d643dcb5c7d79ab364df058.
• Bazel query invocation 5ad9400e-f7b8-4688-9b8c-e962f3de8e66 discovered the affected MCP, delivery, and skill targets.
• Bazel test invocation 13588b19-1f8a-43a7-8006-f9d5d4652670 passed all 12 affected tests, including Buildifier and discovery-link validation.
• Bazel build invocation 5863ac24-3bb2-47be-99fb-50141e933018 passed all 29 affected targets.
• The real launcher initialized, listed all ten gateway tools, and remained live while Bazel query invocation 4637f187-d05e-4905-8153-18fca8644ea1 completed. SIGINT then terminated the server as expected.
• git diff --check passed and the worktree remained clean after validation.

Verdict

The aggregate was published as a single commit on PR 32 and its delivery receipt verified the local tree, remote feature ref, current base ancestry, and PR projection. The exact-head hosted review found three additional issues:

• repository reads reopened a checked symlink through its lexical alias;
• permanent /proc inspection failures could prevent shutdown from settling;
• the process-tree timeout regression assumed Node could start within 100 ms.

The final correction reads through a canonical, no-follow file handle and verifies that handle through /proc/self/fd before consuming bytes, turns repeated process-inspection failures into a bounded EXEC_CLEANUP result, and uses a startup-safe timeout in the process-tree regression. The full MCP test and build packets pass, and both focused targets pass three repeated runs. The review threads are reconciled through the receipt-bound delivery adapter. The follow-up exact-head review found the same replaceable-path class in git_worktree: discovery verified one repository directory, but later Git commands reopened its lexical path. Git discovery and every subsequent command now use /proc/<pid>/fd/<fd> paths backed by verified open directory handles, while the subprocess working directory remains workspace-local. Focused mock coverage checks every Git -C path and the real Cordis starter package integration passes. The next pass found the same class in repo_context’s ripgrep and Git metadata branches; both now use verified descriptor paths for the complete subprocess lifetime, and directory listing uses the selected directory handle as well. Attempt 11 is accepted and the goal is complete. The terminal exact-head review then identified that the JavaScript regular-expression fallback could both block the MCP event loop on pathological backtracking and disagree with ripgrep’s Unicode semantics. The fallback now fails closed for regex requests when ripgrep is unavailable; bounded fixed-string search remains available. Focused and complete MCP test and build packets pass after that correction. The next exact-head pass found that replacement decoding of invalid UTF-8 also changed fixed-search raw byte offsets. The fallback now fails closed for such files as well, leaving raw-byte search semantics to ripgrep; the focused, complete test, and build packets again pass.

Evidence manifest

Back to durable goal

Attempt 8 review-correction evidence

• Recursive JavaScript fallback fails closed when ripgrep is unavailable; explicitly selected files remain supported.
• Fallback fixed and regular-expression submatches use UTF-8 byte offsets.
• Bounded textual HTTP previews omit an incomplete UTF-8 suffix.
• Focused tests pass 2/2 in invocation b73ce3b4-bfb6-4081-b84f-29c3f763b3a4; the complete MCP package passes 7/7 tests in 93845f08-cd10-4dfb-88c5-034497dea58a and builds all 16 targets in d7716a48-9509-44fe-9e37-b5c44904fffd.
• Buildifier passes in invocation 1fb561cc-d336-49db-813f-de26b7fedbe4.
• Follow-up review corrections preserve original-line indexes for Unicode case-insensitive matching, make explicit fallback files override globs, and return healthy scopes plus structured errors from unfiltered listing after partial startup.
• Follow-up focused tests pass 2/2 in c07704be-cdf8-4045-a0c0-4626ebc0d1e7; complete MCP tests pass 7/7 in 3fbaa4e1-8ea1-4b3f-a533-51e1ad01f87b, all 16 targets build in f87e45b6-765e-49c8-a618-cd2eb1efa1ad, and Buildifier passes in 8542838d-92ae-4999-b1e8-fac631629f6f.
• Final review corrections skip every unavailable Include scope and report only retained line endpoints. Fresh correctness scrutiny also preserves startup errors across repeated initialization and limits UTF-8 suffix removal to locally truncated HTTP bodies.
• Focused tests pass 2/2 in 99866999-c31d-457f-b64b-c7a15073e7a2. Combined MCP and repo-delivery tests pass 8/8 in e86a5d1c-cadf-4ff6-9647-3e1050e461e6; all 19 affected targets build in 083fbf55-851e-4db4-b8e5-e5871c874faa. Skill quick validation and Buildifier pass.
• Focused HTTP evidence passes in e80439df-bddd-4a76-b9e1-be6c7f1ed649.
• Runtime evidence uses semantic admission assertions and eagerly attaches the expected timeout rejection; three consecutive runs pass in e7d69598-b843-4da4-833b-e024d406b8ca.
• HMR rollback accepts an already-restored prior cache marker after failed import; otherwise it still waits for an exact correlated reload. Three runtime runs pass in 5f9b49e0-d3d3-4f9e-84ec-602dfbe38c77.
• Regex fallback uses Unicode scalar mode, so . reports one four-byte match for 😀, and the real MCP tool catalog marks cordis_define and cordis_promote as potentially destructive. Both focused regressions pass in 132e2f33-837c-40b2-83b5-4b06ceadfd0f.
• The complete affected packet passes 8/8 tests in b19d303e-0aca-4097-a191-e81015dc2982, builds all 19 targets in 1c8aa274-dd72-4e6f-9491-de5e283b2c5c, and passes Buildifier in 34f6f5c7-7f44-478b-b939-63ac03c3bbb1.
• Fallback context is emitted once in line order and never reclassifies a matching line as context. Bounded reads distinguish a retained empty line from EOF. Focused invocation 2528b6ee-7d82-48c9-a607-298a4cef0b9b passes both regressions.

Attempt 7 working-tree evidence

• The custom manifest.json, hash-named versions/, storage layer, activation worker, and package worker have been removed.
• Official @deepseek-ai/cordis-plugin-loader, -include, -hmr, and -timer packages are pinned. Bazel launches Node with the HMR package’s documented --expose-internals requirement.
• Project entries use projects/mcp_cordis/cordis.yaml and ordinary modules under plugins/; scratch entries use the same layout under out/mcp_cordis.
• Runtime integration proves create, live HMR update, failed activation with on-disk/live rollback, stop, run, promotion, removal, and restart recovery.
• Direct starter-module tests and the complete starter runtime test pass. A real stdio client proves the complete lifecycle, failed-update rollback, package-log isolation, and restart recovery without replacing the MCP process during an update.
• Runtime regressions prove exact source-limit round-trip, invalid-timeout side-effect exclusion, never-settling activation rejection, handler-lease draining, and direct/descendant process-group non-liveness at settlement.
• Affected test and Buildifier invocation 39711671-375a-413f-8a72-e6f9ff892bd3 passed 11/11 on the rebased implementation after the final import-boundary corrections. Affected build invocation 153467fd-e62d-4eab-b260-6754d17fe8e2 passed all 26 targets.
• These full receipts bind implementation commit 0a93e487. Later amendments are confined to the durable goal record and require proportional diff and formatting validation before publication.
• Fresh independent review accepted durable-record commit c05bd45a with no actionable findings.
• PR 32 was republished at the verified rebased head. Its description now records the standard Cordis architecture, and all three obsolete review threads are resolved.

Preflight evidence

• Official OpenAI documentation confirms local Codex clients can connect directly to stdio MCP servers and read server instructions.
• Official DeepSeek documentation states that its dynamic Cordis definitions are process-local and memory-only, establishing the need for the requested persistence layer.
• Cordis 4.0.1 exposes the required Context, plugin, Fiber.await, Fiber.dispose, and effect-scoped cleanup primitives without depending on DeepSeek Harness’s agent/session/browser packages.
• MCP SDK v2 provides a stable stdio server and fixed tool registration. Codex does not reliably refresh dynamically added tool schemas, so the accepted design keeps a fixed list/invoke gateway.
• Repository review selected an ordinary root-workspace Bazel package with a project-owned pnpm lock and Bzlmod dependency fragment.
• Safe aggregate analysis of 40 top-level recent sessions selected repo_context, git_worktree, and network_probe as the initial reusable packages. No transcript or secret-bearing content will be copied.

Attempt 1 verdict

• Architecture: one worker and Cordis root/fiber per active package generation.
• Storage: immutable content-addressed source and atomic manifests in explicit project or scratch scopes.
• Update rule: start and validate a candidate, atomically swap the active generation, then drain and dispose the previous generation.
• MCP rule: stdout is protocol-only; package output is redirected to stderr and out/mcp_cordis/logs.
• Candidate hash: c9300c9887104777c8915e3d4f390196604e9bd18497bbec319415d1a4ad057f.
• Focused query, lifecycle/in-memory MCP, and subprocess stdio tests pass.
• Starter execution test fails at repo_context_search with spawn rg ENOENT; candidate rejected and Attempt 2 opened.

Attempt 2 verdict

• Candidate commit: e3e74cb1e573867825347292bf17220a5b9a4a0c.
• Candidate tree: 079a0c27b86527c6950cc75b0c8b9dbf572d3e4b.
• Fetched base and direct parent: 7ad2704cd27757355ab36ec8eb1bb27ef9e1d91d.
• The delivery preparation receipt confirms an exact, conflict-free rebase, task-only path scope, and absence of a remote feature ref or pull request.
• Focused post-rebase query passes.
• Integrated post-rebase result: three of four tests pass. Starter packages, stdio, and build coverage pass; lifecycle evidence fails at an elapsed-time drain precondition with actual 0, expected 1.
• Verdict: refine the test evidence in Attempt 3; do not change the runtime architecture based on this measurement.

Attempt 3 verdict

• Final local commit: 7cfef0719075ad372c3bb257ad216b35770356b2.
• Final local tree: 34153eca0f582af5c641f81bf8c7209b0045ab9a.
• Direct parent and fetched base: 7ad2704cd27757355ab36ec8eb1bb27ef9e1d91d.
• Forced project tests: four of four pass on the exact commit.
• Complete project build: nine of nine targets pass.
• Forced root Buildifier and exact commit diff check: pass.
• Review verdict: accept as the final local candidate. Publication was stopped before execution because a rebase-only request does not authorize remote push/PR mutation.

Attempt 4 preflight

• PR 32 was published at exact commit 7cfef071; remote branch and PR tree matched the local receipt.
• Current remote master is 7ad2704c, the direct parent of the published task commit; repository inspection reports needs_rebase: false.
• PR 24 head is da2085f1, based on ada3ed90. Its projects/agents diff is exactly four files: one bazel-agent update, one goal update, and two new decision-review files.
• Three PR 32 review threads were independently diagnosed as valid. Their controlling fixes are bounded-success execution, pre-record change limits, and shutdown admission closure followed by lock draining.
• Verdict: reject 7cfef071 as final; proceed with the scoped three-way import and three behavior-changing corrections in Attempt 4.

Attempt 4 working-tree evidence

• PR 24 import: bazel-agent batching guidance, result-first goal guidance, and the exact decision-review instruction blob are present. Newer throwaway-record and bounded-delegation guidance remains intact.
• Execution overflow now retains a combined arrival-order byte prefix, returns only valid UTF-8, stops live process-group members, and reports truncated rather than rejecting. Timeout and spawn errors retain rejection semantics.
• git_worktree keeps 70d8... as immutable history and activates new exact content hash de978...; its record limit is checked before every porcelain record matcher.
• Shutdown closes admission, joins the exact admitted package-lock snapshot, then disposes the final active set and awaits retirements through one memoized promise. Initialization rechecks closure after awaited storage boundaries.
• Four focused Bazel tests pass, including all new regression targets and decision-review offline validation.
• Integrated Bazel test invocation passes ten of ten tests: the whole MCP package plus all three imported/updated skill configurations.
• Full affected build passes and validates bazel-agent, goal, and decision-review; root Buildifier passes.
• Verdict: behaviorally acceptable as a working-tree candidate. Independent diff review and exact commit-bound validation are still required.

Attempt 4 independent-review verdict

• Max-change review proved the bound placement but rejected the completeness flag when exactly maximum records exist, the missing second-record test, and newline-unsafe pathname capture.
• Execution review accepted byte bounding, process-group cleanup, and runfiles, but rejected silent invalid-UTF-8 loss and incomplete propagation of host truncation through reusable package result fields.
• PR 24 provenance review accepted the three-way import and packaging, but found no eval cases for compatible Bazel batching, immutable candidate promotion, or durable-versus-throwaway push behavior.
• Verdict: refine; passing Attempt 4 checks do not qualify it for commit.

Attempt 5 working-tree evidence

• Execution tests cover ASCII overflow, multi-byte boundary overflow, malformed UTF-8 both below and above the byte cap, combined stdout/stderr budgeting, timeout rejection, normal nonzero exit, and process-group non-liveness at settlement.
• git_worktree active hash is 8853aa20665778aeec43e03f2fe975445002d56ed33ea1cf38bef3946381f60d; its manifest retains only that version and unchanged historical hash 70d8f28dc947d19410b8e79bad90cb416303107243d72d062dd70e30f97a2c3b.
• repo_context active hash is abd0db3e26ec970dcf5cc3ec21b9f2b2c452f9302edc0e10c5231a140b92fbc0; all three manifest version hashes match their exact source bytes.
• Focused MCP regressions and three skill eval configurations pass 8/8.
• Full affected test packet passes 12/12; full affected build and three rules_skill validation aspects pass; root Buildifier passes 1/1.
• Exact commit and post-rebase evidence remain pending, so this is a green working-tree candidate rather than a delivered checkpoint.

Attempt 6 working-tree evidence

• Current immutable starter hashes are 04b06a7d6277c4a6e8513d970f549ad980a780b68755f28d7b402fe8be26c279 for git_worktree and 94131e058f82328f091613dc68d2717484378066a9c64940d99522c14b48b4d7 for repo_context; line wrapping does not introduce whitespace into the first identifier.
• Historical version bytes retain their exact filename hashes. The checkout enforces LF for every hash-addressed JavaScript source.
• The parent activation now owns every ctx.exec() child handle. Focused tests prove immediate live-process absence after inner timeout, outer timeout, startup timeout, output overflow, normal completion with a background child, and a background child inheriting output pipes.
• Runtime regressions prove shutdown admits complete promotion, rolls back a candidate that fails during active-version persistence, and actively disposes a retired generation whose admitted handler remains gated.
• Bazel invocation 9b1b2d34-8490-474a-b12c-e2052bf2d90b passes the current process, unavailable-shutdown, and runtime-admission targets 3/3.
• Bazel invocation 7c680be8-e2a6-4b5b-9b45-4a0390f39a5a passes the current process, ripgrep-byte-field, and runtime-admission targets 3/3.
• Fresh whole-diff and adversarial supervisor reviews are running. Full integrated, build, skill-aspect, Buildifier, exact-commit, rebase, and remote verification remain unverified after the latest changes.

Attempt 10 focused HMR evidence

• Subject: dirty Attempt 10 tree using @deepseek-ai/cordis-plugin-hmr 1.0.16 with pnpm patch hash ec800d86298faacc86c7717ffa1dce7c28116ab1393b8abc198be6ac02c38489.
• Primary dependency evidence: the npm registry lists 1.0.16 as the latest release, and current upstream vendor/hmr/src/index.ts retains the same untracked debounced partialReload() plus shared-stash reset behavior.
• Independent reproduction: a slow top-level-await generation followed by a second write reached {live: "slow", diskLatest: true} with the unpatched package.
• Patch applicability: git apply --check accepts patches/hmr@1.0.16.patch against the exact resolved 1.0.16 package files.
• Lock generation: Bazel-managed pnpm invocation a1c50484-20c6-4935-8832-92029d0de3c6 completed successfully with no unrelated dependency resolution changes.
• Causal runtime regressions: Bazel invocation ac79a8e4-f5d9-4dd7-a821-29bce3d8ece6 passed explicit release-gated top-level evaluation and asynchronous activation overlaps, failed apply rollback and recovery, manual editing, and deterministic disabled activation.
• Repetition: Bazel invocation 65c1932a-896b-470d-9462-086dd93beaff passed ten runs each of runtime_test and starter_packages_test.
• Complete project packet: invocations 6490dd57-49e0-4558-b280-f5625db07208, 218e5797-b2d7-44bc-aded-f5df8139ca1c, and 09d4ec2c-aac1-4509-8579-5ef8c5eebe39 passed all project tests, all project builds, and root Buildifier respectively.
• Project-layout adaptation: Bazel invocation ea2c6c6e-b2e1-425d-bedb-2ac9679de6c5 passed runtime_test after moving the command, internal implementation, launcher, and test suite to their role-based directories.
• Independent final HMR review accepted patch identity, stashed-change draining, complete Fiber cleanup join, declarations, causal overlap tests, rollback and recovery, and disabled-entry activation. Its only finding was a README sentence describing the superseded publication order; that contract text is corrected in the current tree.
• The real cmd/mcp_cordis/launch.sh completed MCP initialization and listed all ten tools. While that stdio server remained live, Bazel query invocation 7739c14e-1b22-40c7-94af-b81143e84d4a completed successfully, proving the launcher releases the workspace Bazel lock before serving; SIGINT shut the server down cleanly.
• Preliminary current-tree Bazel invocations 95d37231-63f9-44f6-9eee-3f0fe8fb4107, d70f61a2-57e5-4ce9-b8fd-27b06bd02a6d, and 1e186c82-3bcd-4048-a534-fe747e1cf79c pass the complete affected test packet (10/10), affected build packet, and root Buildifier check.
• Guarded delivery inspection bound same-repository PR 32 to local and remote feature OID bc4e5ae97ef9ea968c01b1b2a55403ae032a6a8d, fetched base OID d29f9d471ea467e8dfc75db4eedeedbbae43dc2d, and SSH transport. All nine linear feature commits have the task-bot author and committer identity; the only refusal is version 1’s unconditional multi-commit consolidation guard, which is unchanged on the fetched base.
• The user explicitly authorized the narrow adapter extension. Its exact-head consolidation path verifies linearity, identity, oldest ownership marker, pull-request metadata matching the requested aggregate projection, signature requirements, and every other inspection refusal before creating one aggregate commit. Integration coverage proves that the pre-consolidation remote head remains the receipt-bound publication lease.
• Bazel invocations 574dadd5-51b1-443e-b8c2-50ca5d257eb2 and 030a8bb4-2a22-4ece-b632-b3c75572bcee pass the complete adapter suite once, then its Go, skill-validation, and root Buildifier targets three times.
• Independent adapter review rejected the first implementation because clean ranges had no staged delta. The correction permits an unchanged index only behind validated exact consolidation evidence, while parent-to-tree scope validation continues to reject an empty aggregate. A clean --path regression proves tree preservation and one final commit; Bazel invocation 0d715375-6a8d-4269-ad3e-f8a002888808 passes, and independent re-review accepts the corrected adapter with no remaining findings.
• After adding upstream-compatible root-consumer visibility to the branch-owned decision-review skill, Bazel invocations 6099d90d-0ade-43b2-b50b-8f7050c26c32 and 7f4b37a4-b970-46ea-bc76-b4a60aeeab59 pass its focused validation and the root Buildifier check; git diff --check also passes.
• Guarded consolidation and rebase produced one candidate commit on fetched base 63e7b9f0be1e054373415914ff3d2ea2282aa3da. The adapter now stages deletions and symlink-to-directory changes and permits a rebased path to vanish only when the old candidate and new base have the exact same Git tree entry.
• Exact code-candidate Bazel invocations 13588b19-1f8a-43a7-8006-f9d5d4652670 and 5863ac24-3bb2-47be-99fb-50141e933018 passed all 12 affected tests and all 29 affected builds, including Buildifier and discovery-link validation. Live launcher initialization listed all ten gateway tools while concurrent query invocation 4637f187-d05e-4905-8153-18fca8644ea1 passed.
• Verdict: the focused race, recovery, layout, repeated-run, project-wide, consolidation, and exact code-candidate evidence pass. The final adapter-and-record rewrite, remote publication, hosted review reconciliation, and final receipt verification remain open.

Attempt 11 final review evidence

• Guarded publication and receipt verification established a clean, single-commit feature branch on base 63e7b9f0be1e054373415914ff3d2ea2282aa3da, with the local and remote tree identical and PR 32 synchronized.
• The exact-head hosted review completed against the published aggregate and reported three actionable findings: lexical symlink reopening, unbounded /proc inspection retries, and a 100 ms process-start assumption.
• Repository reads now open the canonical target with O_NOFOLLOW, validate the opened descriptor through /proc/self/fd, inspect and read through that same handle, and retain the existing byte bound. A regression proves an internal symlink read never reopens the lexical alias through ctx.readText.
• Process-group verification now skips inaccessible per-PID entries and turns three consecutive inspection failures into EXEC_CLEANUP; a direct regression proves the retry bound. The timeout cleanup fixture now allows a five-second startup window before exercising forced group cleanup.
• Bazel invocation d32cccf7-b5b9-427c-93a1-6b612e32a0aa passed all seven MCP tests. Invocation 9d11ce11-1f79-4077-b61a-efa95a5fc3de built all 16 MCP targets. Invocation aadcc7f6-e2b3-4480-8b76-0607b2017415 passed three runs each of the process-supervisor and repository-context regression targets.
• Final publication, exact-head review completion, thread reconciliation, and receipt verification are performed by the guarded delivery workflow; the ignored receipt is the authoritative mutable delivery record.
• Follow-up exact-head review identified lexical reopening in git_worktree. Repository selection and discovered-root use now retain verified directory handles for the complete tool call, and all Git -C arguments address those handles through /proc/<pid>/fd. The focused command-contract test and real Cordis starter-package integration pass together in Bazel invocation 4c3eba8d-32c9-47e9-a257-f8af92ef0c19; invocation 6c638120-90cb-446c-b76e-6d39df3640e5 repeats both targets three times. Invocations ef83ec38-84ed-466e-abbd-ffd6cef892c1 and 16e0c322-adc7-4763-8ff4-11d5f38a4172 pass the complete seven-test and sixteen-target MCP packets.
• The next exact-head pass identified the same lexical reopening in repo_context’s ripgrep and Git metadata branches. Selected search paths and repository directories now remain open while subprocesses address them through /proc/<pid>/fd; reported ripgrep paths are mapped back to stable workspace-relative names. Directory kind and entry inspection also use the selected handle. Bazel invocation a3f4ed56-a44b-46d6-8717-c38ecc7f05eb passes the focused context contract and real ripgrep/Git starter integration together. Invocation e7af6e8f-823e-40ef-a833-dcb0a704f46f repeats both three times, while invocations 9fd4d465-957a-424f-9bb8-f6e10eb93009 and 4a464ddd-f646-4b9a-aaab-a411bf930ee0 pass the complete seven-test and sixteen-target MCP packets.
• The terminal exact-head review found that the JavaScript regex fallback could monopolize the MCP event loop through backtracking and could not match ripgrep’s Unicode regex semantics. Regex search now requires ripgrep when the executable is unavailable, while the bounded fixed-string fallback is preserved. Bazel invocation b98534c0-1667-462b-81d5-ee393fca343b passes the focused context and real starter integration targets; invocations 4689e7cb-9600-4b35-ad7a-97e02cd6730c and 557f322c-4fad-4358-bf5f-98ad9b8972b0 pass the complete seven-test and sixteen-target MCP packets.
• The next exact-head pass found that invalid UTF-8 replacement decoding changed fixed-search byte offsets when ripgrep was unavailable. The fallback now verifies that decoded text round-trips to the original bytes and fails closed otherwise. Bazel invocation 449ea2c4-4d52-44d2-b7d1-b1e9745359bd passes the focused context and real starter integration targets; invocations 77bae252-af20-4242-89d8-7d6bc242b64f and 3a0bd136-a327-416a-8128-aaaec171bd9c pass the complete seven-test and sixteen-target MCP packets.

Failure ledger

Back to durable goal

Attempt 8 hosted review finds starter fallback and encoding gaps

• Candidate: published standard-Cordis commit deaa2dcd.
• Result: hosted review found three valid defects after the earlier local whole-diff review had accepted the runtime architecture.
• Causes: the no-ripgrep fallback recursively traversed ignored and hidden files, JavaScript string indexes were exposed as byte offsets, and a bounded textual HTTP body decoded an incomplete trailing UTF-8 sequence.
• Strategy delta: fail closed for directory fallback, retain explicit-file fallback with true UTF-8 offsets, and decode only a complete UTF-8 prefix.
• Regression guard: explicit hidden-file versus directory cases, fixed and regex non-ASCII offsets, and a one-byte multibyte HTTP preview must pass with the complete MCP test/build packet.
• Follow-up causes: lowercasing a line could change UTF-16 length before offset projection, fallback glob filtering contradicted ripgrep’s explicit-path precedence, and unfiltered listing did not preserve a healthy scope after partial startup.
• Follow-up guard: length-changing İx, explicit file plus excluding glob, and malformed-project/healthy-scratch listing cases pass with the complete MCP packet.
• Final-review causes: config parsing alone did not identify a scope whose Include never mounted, and bounded reads reused the requested endpoint after clipping content.
• Fresh-scrutiny cause: idempotent initialization returned an empty error list after partial startup because only the first call retained local failures.
• Additional fresh-scrutiny cause: UTF-8 suffix trimming did not distinguish a byte-cap split from a naturally completed malformed response body.
• Final guard: missing-module and malformed-config scopes are both skipped by unfiltered listing, clipped reads report retained endpoints, and repeated initialization preserves structured scope errors. Textual bodies trim an incomplete suffix only when locally truncated. repo-delivery now makes this correctness scrutiny an explicit post-edit gate.

Exact aggregate runtime evidence was timing-sensitive

• Candidate: post-review Attempt 8 aggregate validation.
• Result: the complete packet failed only when system load delayed a wall-clock <400 ms assertion and allowed an expected 300 ms rejection to occur before its assertion was attached.
• Cause: the test inferred synchronous admission from elapsed time and created a temporary unhandled-rejection window while waiting for a PID file.
• Strategy delta: assert the wrapped synchronous-admission error semantics and attach the expected rejection before awaiting the fixture handshake.
• Regression guard: the complete runtime target passes three consecutive concurrent runs without loosening production deadlines.

Failed-import rollback waited for an event Cordis does not emit

• Candidate: loaded exact aggregate validation after the evidence correction.
• Result: a failed source update occasionally reported reload_rollback_failed even though Cordis had already restored the prior module cache.
• Cause: failed HMR import restores its cache and returns without emitting hmr/reload; the host always required a second reload event after restoring prior bytes.
• Strategy delta: after restoring bytes, accept the exact prior cache marker immediately; retain correlated HMR waiting when the failed candidate marker actually reached the cache.
• Regression guard: three concurrent runtime runs prove failed-update rollback, source restoration, and subsequent healthy invocation.

Attempt 1, check 1: npm repository analysis

• Command: bazel_agent bazel query //projects/mcp_cordis:all
• Result: failed before target analysis.
• Cause: rules_js requires pnpm v10 workspaces to declare onlyBuiltDependencies, including when lifecycle actions are disabled.
• Evidence: repository fetch failed in verify_lifecycle_hooks_specified with that exact requirement.
• Strategy delta: declare an empty lifecycle allowlist in the project-owned workspace and regenerate its exact lock before rerunning the same query.
• Regression guard: successful focused query and build of the translated npm repository.

Attempt 1, check 2: package query after npm correction

• Command: bazel_agent bazel query //projects/mcp_cordis:all
• Result: npm translation succeeded; target loading stopped because the deliberately non-empty starter-package glob had not yet been populated.
• Cause: implementation was queried while the parallel starter-package draft was still outstanding.
• Strategy delta: retain the non-empty invariant and add the three accepted packages before rerunning the same query.
• Regression guard: the starter_packages target must contain real files and the focused query must succeed.

Attempt 1, check 3: runtime test process did not terminate

• Command: bazel_agent bazel test //projects/mcp_cordis:runtime_test
• Result: both test bodies completed in under 400 ms, one failed, but a worker retained by the failing test kept the process alive until the run was interrupted at 144 seconds.
• Cause: the test registered cleanup only along its success path, so the first assertion failure leaked its runtime and obscured the underlying defect.
• Strategy delta: register unconditional node:test teardown before the first assertion, then rerun to expose the real behavioral failure promptly.
• Regression guard: the target must terminate normally on both passing and failing assertions.

Attempt 1, check 4: activation error assertion mismatch

• Command: focused runtime test after unconditional teardown.
• Result: target terminated in 0.8 seconds; the MCP gateway test passed and the lifecycle test stopped at its syntax-rollback assertion.
• Cause: the runtime correctly exposed activation_failed as the error’s machine-readable code, while the test searched only its human message.
• Strategy delta: assert the stable code and separately check the underlying syntax diagnostic.
• Regression guard: failed activation retains the working v2 generation and reports both the stable wrapper code and candidate cause.

Starter search depends on undeclared ripgrep (occurrence 1)

• Command: bazel_agent bazel test //projects/mcp_cordis:starter_packages_test.
• Result: failed in 0.4 seconds with spawn rg ENOENT.
• Cause: repo_context_search invoked the preferred ripgrep engine without a fallback, while the Bazel test PATH intentionally does not expose the host installation.
• Attempted strategy: none before this measurement.
• Strategy delta: Attempt 2 adds a bounded in-process fallback while retaining ripgrep when available.
• Regression guard: the unchanged hermetic starter test must exercise a successful search and all remaining package handlers.
• Latest result: resolved in Attempt 2. The unchanged hermetic test passes with the new bounded JavaScript fallback and executes all eight tools.

Lifecycle drain test uses an elapsed-time race (occurrence 1)

• Command: bazel_agent bazel test //projects/mcp_cordis:all on rebased commit e3e74cb1e573867825347292bf17220a5b9a4a0c.
• Result: three test targets pass; runtime_test reports actual drain count 0, expected 1.
• Cause: the test delays the old request for 150 ms but must start and validate a replacement worker before retirement. Nothing guarantees the swap occurs before the fixed request delay expires.
• Attempted strategy: a 20 ms sleep before starting replacement; this proves that the old request started, not that it remains active at the later swap.
• Strategy delta: Attempt 3 uses an explicit started marker and release latch.
• Regression guard: run the focused lifecycle test and complete suite with no wall-clock assumption controlling the drain-count assertion.

BUILD data labels not in Buildifier order (occurrence 1)

• Command: bazel_agent bazel test //:buildifier_test during Attempt 3.
• Result: failed with an exact three-line ordering diff in projects/mcp_cordis/BUILD.bazel.
• Cause: the external-style :node_modules/... label followed the two shorter local labels in runtime_test.data.
• Strategy delta: apply Buildifier’s exact lexical ordering and rerun the same repository formatter target.
• Regression guard: //:buildifier_test must pass on the frozen candidate.
• Latest result: resolved. The forced Buildifier test passes on commit 7cfef071.

Remote publication lacks explicit authorization (occurrence 1)

• Intended command: repository delivery publish using the exact preparation receipt and validated head 7cfef071.
• Result: the approval gate rejected execution before any push or pull request mutation.
• Cause: the latest user instruction explicitly requested a rebase and did not authorize the separate consequential remote publication operation.
• Safe attempts: preparation, exact-tree validation, and local commit are complete; no workaround or indirect mutation was attempted.
• Exact unblocker: explicit user authorization to push this branch and create or update its pull request.
• Latest result: resolved. The user explicitly requested push and continued goal execution; PR 32 was published at 7cfef071 and remains the authorized delivery vehicle for the corrected candidate.

Published candidate has three valid review defects (occurrence 1)

• Candidate: PR 32 commit 7cfef0719075ad372c3bb257ad216b35770356b2.
• Result: automated review found three independently reproducible defects.
• Causes: output overflow rejects instead of returning bounded data with a truncation marker; branch records bypass max_changes; shutdown snapshots active workers before an admitted activation finishes.
• Strategy delta: Attempt 4 changes each controlling mechanism and adds a black-box regression for each, rather than suppressing or merely replying to the review.
• Regression guard: republish only when all focused tests, the full MCP Cordis package, imported skill validation, and Buildifier pass on one exact commit.
• Latest result: resolved in the Attempt 4 working tree. Four focused tests, all ten integrated tests, the complete package build, three skill-validation aspects, and root Buildifier pass. Exact-commit rerun remains required.

Attempt 4 independent review rejects completeness claims (occurrence 1)

• Candidate: uncommitted Attempt 4 working tree after all recorded tests passed.
• Result: four directly related semantic and evidence gaps survived.
• Causes: invalid UTF-8 loss did not set truncated; several starter fields ignored host truncation; Git status inferred truncation from result length instead of actual omission and used newline-unsafe path regexes; imported skill eval cases did not exercise their new contracts.
• Strategy delta: Attempt 5 makes loss explicit, propagates truncation by field, parses one-record lookahead semantics, adds newline/exact-limit tests, and expands offline eval cases before another integrated run.
• Regression guard: independent review must find no correctness issue before delivery preparation; a green test suite alone is insufficient.

Unavailable worker teardown escapes shutdown tracking (occurrence 1)

• Evidence: independent shutdown review of Attempt 4.
• Cause: #handleUnavailable() removes the activation from #active, while its worker termination is asynchronous and was not added to #retirements.
• Strategy delta: track the activation’s idempotent dispose() promise as a retirement at the same moment it is removed.
• Regression guard: a deterministic unavailable-then-shutdown scenario must prove shutdown does not finish before the teardown promise.

Main references an absent decision-review skill (occurrence 1)

• Evidence: current base 7ad2704c mentions decision-review in AGENTS.md, but the referenced package is absent from that tree.
• Cause: the skill exists in open PR 24, not in the rebased master commit.
• Strategy delta: import only PR 24’s four projects/agents changes, merged against current guidance, and supply validation assets required by current repository policy.
• Regression guard: build and validate the imported skill through its Bazel skill_library and offline Promptfoo target.
• Latest result: resolved in the working tree. decision-review matches PR 24’s instruction blob and passes quick validation, offline Promptfoo loading, and the repository skill-validation aspect.

Attempt 5 independent review rejects lifecycle and compatibility

• Candidate: green uncommitted Attempt 5 working tree.
• Result: focused tests passed 8/8, integrated tests passed 12/12, the affected build and skill aspects passed, and Buildifier passed; independent review nevertheless found release-blocking defects.
• Causes: immediate Worker.terminate() can bypass detached-child cleanup; already-admitted handlers can spawn after one-shot disposal cleanup; promotion is outside the shutdown lock snapshot; an unavailable candidate’s one-shot notification can be ignored during persistence; and always-success output truncation silently changes retained package-version semantics.
• Additional gaps: command signals/failures, exact-bound search and omitted records, Git optional writes/history framing, LF hash portability, weak integration assertions, and contradictory or domain-specific imported-skill rules.
• Strategy delta: Attempt 6 versions partial-output behavior explicitly, closes process and runtime admission, creates sole final package candidates, and binds every completeness claim to a direct regression.
• Regression guard: no delivery preparation until a fresh review accepts the new candidate after all invalidated gates pass.

Attempt 6 first final review rejects worker-side process ownership

• Candidate: green Attempt 6 working tree before parent-owned supervision.
• Result: focused tests, the 14/14 integrated packet, build, skill validation, and Buildifier passed; independent reviews still rejected release.
• Causes: outer timeouts settled before cleanup; signaling a process group was called reaping; the worker’s native-spawn/PID-publication window could not be both bounded and orphan-safe; direct exit could leave inherited pipes open; shutdown awaited but did not dispose retired generations; ripgrep byte fields could be returned as empty complete text; and durable records were stale.
• Strategy delta: the parent activation now owns process spawning and group cleanup, runtime tracks retired activations rather than only their promises, byte fields set explicit truncation, and the durable goal records every verdict and invalidated gate.
• Regression guard: immediate non-liveness assertions, inherited-pipe cleanup, fatal cleanup ordering, retired-generation shutdown, byte-field cases, and a fresh adversarial review must pass before final integrated validation.

Custom manifests and hash versions are the wrong extension model

• Candidate: published PR 32 checkpoint 7cfef071 and its Attempt 6 descendants.
• Result: the user rejected the per-package manifest.json, immutable versions/, and active-pointer design as nonstandard and temporary-looking.
• Cause: the runtime had grown a second package manager instead of using Cordis Loader entries, Include-backed configuration, HMR, and Git history.
• Strategy delta: Attempt 7 deletes the custom store and workers, pins the official services, and uses cordis.yaml plus ordinary ESM modules.
• Regression guard: no package manifest, hash-named source snapshot, custom storage layer, or version-file .gitattributes rule may remain.

In-process standard Cordis needs reliability admission guards

• Candidate: independently reviewed Attempt 7 working tree.
• Result: review found that accidental stdout writes could corrupt stdio, Promise/async-iterator activation or top-level await could wedge lifecycle mutation, filename-only HMR events could acknowledge the wrong write, and response timeout could leave invocation-owned children running.
• Strategy delta: reserve a private protocol stream, use Node’s ESM parser to reject top-level await, require synchronous object activation, correlate managed source with a named-export token, and use an invocation-scoped supervisor that cancels and joins ctx.exec().
• Regression guard: real stdio logging, hung activation, source round-trip, invalid/expired invocation, and descendant non-liveness tests all pass.

Official HMR requires Node internal-module access

• Command: first Attempt 7 runtime_test initialization.
• Result: HMR rejected startup with --expose-internals is required for HMR service.
• Cause: the optional native fallback peer was not reliably visible through Bazel’s strict pnpm layout.
• Strategy delta: every runtime-bearing Bazel launcher passes the official package’s supported --expose-internals Node flag. Automatic peer install is disabled because all required peers are pinned explicitly and the optional native fallback is unnecessary.
• Regression guard: the complete project build and all runtime tests must boot through the Bazel launchers.

Root Fiber uid zero skips watcher disposal

• Command: runtime and starter tests without Node’s force-exit option.
• Result: both test bodies passed but timed out with live FSEventWrap resources after runtime.shutdown().
• Cause: shutdown guarded root.fiber.dispose() with root.fiber.uid; Cordis assigns the root Fiber uid 0, so the truthiness check skipped every root-owned cleanup effect, including HMR watchers.
• Strategy delta: dispose whenever the root Fiber exists, independent of its numeric uid. Remove force-exit workarounds from tests and keep stdio shutdown graceful.
• Regression guard: runtime, starter, and real stdio tests must exit normally without --test-force-exit or process.exit().

Review completion is not thread reconciliation

• Candidate: published commit cfab0fb5 after a completed hosted review.
• Result: the review summary completed, but GraphQL thread inspection exposed one unresolved older regex-parity finding and one new annotation finding.
• Cause: regex fallback omitted JavaScript Unicode mode and matched surrogate halves; source-overwriting MCP tools declared destructiveHint: false.
• Strategy delta: enable Unicode scalar matching, mark both potentially overwriting tools destructive, and treat the review-thread graph—not the summary state—as the authoritative review ledger.
• Regression guard: an astral . fallback match must be one UTF-8 span, and real stdio tool discovery must expose both destructive annotations.

Fallback event and empty-range boundaries diverge

• Candidate: published review correction bc4e5ae9.
• Result: the next hosted review found duplicate, out-of-order fallback context around adjacent matches and a null endpoint for an existing empty line.
• Cause: context filtering knew only the current matching line, while bounded reads inferred range existence from non-empty selected text.
• Strategy delta: precompute match classifications, emit the union of match and context lines once in source order, and track whether the requested range exists separately from its content.
• Regression guard: adjacent matches followed by context must emit match/match/context in line order; a selected empty line reports its line number while a start past EOF reports null.

Delivery adapter refuses the multi-commit feature range

• Candidate: local Attempt 9 changes above published head bc4e5ae9, with fetched base d29f9d47.
• Result: read-only delivery inspection reports nine feature commits and refuses preparation; version 1 will not infer consolidation ownership.
• Cause: only the first commit carries the adapter’s ownership disclaimer, while the adapter supports preparation of at most one feature commit.
• Rejected workaround: direct rebase, reset, cherry-pick, or a replacement branch would bypass the GitHub adapter’s explicit safety refusal.
• Required strategy delta: obtain scope to add a guarded exact-head, merge-base-aware consolidation path to repo_delivery, or have that support land separately before resuming the rebase.
• Resolution: the user explicitly authorized a guarded adapter extension. repo_delivery prepare --consolidate <exact-inspected-head> now verifies a merge-free linear range, identical author and committer identities, the oldest commit’s ownership marker, unchanged pull-request projection, signature preservation, and every unrelated refusal before replacing the range. Its integration test also proves the prior remote tip remains the receipt-bound publication lease.

Cordis HMR loses a write during an in-flight reload

• Candidate: Attempt 9 with unmodified @deepseek-ai/cordis-plugin-hmr 1.0.16.
• Result: a deterministic slow top-level-await replacement followed by a second write left the latest source on disk but the first replacement live.
• Cause: debounced partialReload() work was not serialized; each successful run reset one shared stash even when a later change arrived during import.
• Rejected wrapper workaround: public HMR emits neither import-failure nor settled-activation events, so a wrapper gate would either reopen unsafely on a timeout or wedge permanently after failure.
• Strategy delta: Attempt 10 uses standard pnpm patching to serialize the owning HMR task, snapshot each change set, and drain changes observed while it runs.
• Regression guard: overlapping writes during both slow module evaluation and slow asynchronous activation must converge to the latest persisted source.

Requirements and constraints

Back to durable goal

User requirements

• The project is named mcp_cordis and lives under projects/.
• Reuse Cordis itself rather than reimplementing its lifecycle architecture.
• Keep reusable runtime code under the project for later reuse.
• Keep disposable runtime code under out.
• Seed the project with packages based on recurring past-session needs.
• Security hardening is not the priority on this dedicated LLM machine.
• Codex must load the MCP from project-scoped configuration so different clones and linked worktrees use their own source and disposable state.

Repository constraints

• Use bazel_agent for every Bazel command.
• Pin external dependencies reproducibly and retain required notices.
• Keep disposable task scratch under out/mcp_cordis; maintain this explicitly requested reusable goal under projects/mcp_cordis/goals.
• Preserve unrelated working-tree changes.
• Prefer a narrowly scoped project and focused validation.

Assumptions

• “Based on past sessions” means extracting generic recurring workflows, not copying private conversation text, credentials, or secret-bearing data.
• Host-only JavaScript packages are the initial scope; browser UI packages are not required for the first working server.
• A stable gateway invocation tool is required because MCP clients differ in when they consume tool-list change notifications.

Requirement changes

• 2026-08-30: project name changed from agent_extension_host to codex_cordis, then finally to the client-neutral mcp_cordis.
• 2026-08-30: storage clarified as two-tier: reusable project packages and disposable out packages.
• 2026-08-30: the user promoted the runtime-extension goal directory from disposable out coordination to durable project documentation for future reuse.
• 2026-08-30: remote master advanced and the user explicitly requested a rebase before implementation continued. The task commit was rebased from 775f44d3b56146005e44980f3cf948785f963ba0 onto 7ad2704cd27757355ab36ec8eb1bb27ef9e1d91d; all prior checks were treated as invalid until rerun.
• 2026-08-30: after publication, the user explicitly expanded the delivery to include only the projects/agents subtree changes from PR 24. PR 24 changes four files there: bazel-agent, goal, and the new decision-review package. Import those changes three-way against current master; do not import its unrelated render or infrastructure content.
• 2026-08-30: the user rejected the custom per-package manifests and requested standard solutions. Runtime persistence must use official Cordis loader entries and cordis.yaml; normal reusable files and Git replace committed content-addressed source history.
• 2026-08-30: after review-driven fixes exposed additional correctness gaps, the user required repo-delivery to invalidate prior correctness verdicts after code changes and require fresh diff-focused scrutiny beyond green tests.
• 2026-08-30: the user rejected the HMR race-handling complexity and explicitly required the simplest robust MCP wrapper for loading DeepSeek/Cordis plugins. Source-tool success therefore means validated atomic persistence and an official Cordis load/reload request, not a custom synchronous activation transaction or on-disk rollback protocol.
• 2026-08-30: the user required per-workspace Codex loading. The checked-in .codex/config.toml must resolve the active linked worktree; the launcher must release Bazel’s output-base lock before the MCP begins serving stdio.
• 2026-08-30: remote master advanced again to d29f9d471ea467e8dfc75db4eedeedbbae43dc2d. The user requested another rebase and incorporation review. Preserve the new projects/goal redesign and do not resurrect its deleted predecessor under projects/agents.
• 2026-08-30: after the delivery adapter refused the exact nine-commit task range, the user explicitly authorized extending repo_delivery with a guarded exact-head consolidation operation and then repeated the request to rebase, review, and incorporate the upstream changes.
