Assistant execution summary

This continuation deliberately prioritized the current executable critical path instead of opening another theory/research lane.

The main result is a much stronger, exact-head real-worker candidate in PR #91 plus a precise independent Docker acceptance protocol in issue #37.

---

1. Rechecked the live P0 state

At the beginning of the turn, the repository had already advanced beyond the previous snapshot:

• the executable local verifier from PR #72 was on main;
• issue #4 explicitly allowed the deterministic two-attempt coordinator slice;
• PR #51 still represented the repository-side fail-closed/branch-protection work, while actual GitHub main protection remained an admin configuration issue;
• the old canonical-node PR #34 was still open/stale at first inspection.

The key rule for this turn became:

Do not duplicate work that concurrent contributors/agents have already landed; converge on one implementation and spend reviewer attention on missing evidence.

---

2. Began a two-attempt orchestrator, then closed it when equivalent work landed

A branch orchestration/two-attempt-kernel-v0 and PR #87 were initially created with:

• exactly two isolated fixture attempts;
• canonical ResultManifest generation;
• independent local-verifier routing;
• deterministic replay signatures;
• worker-failure isolation;
• no automatic integration;
• unit tests and CI.

While PR #87 was opening, equivalent implementation from PR #78 appeared on main, including:

• experiments/two_attempt_orchestrator.py;
• examples/orchestration/two-attempt-good-vs-bad.json;
• examples/orchestration/two-attempt-worker-failure.json.

Issue #4 also recorded the merged deterministic coordinator baseline.

PR #87 was therefore explicitly closed as superseded rather than raced against the already-landed implementation.

Durable collaboration lesson

A self-evolving repository must optimize not only for generation but also for convergence:

parallel ideas
 -> detect semantic overlap
 -> select/reconcile one useful implementation
 -> close duplicates visibly
 -> preserve scarce review capacity

Raw PR count is not progress if two PRs solve the same problem.

---

3. Isolated the real remaining issue #4 blocker

After PR #78, the deterministic control-plane baseline existed. The missing critical-path component was the real bounded worker plus independent runtime evidence:

canonical WorkUnit
 -> real bounded worker
 -> ResultManifest
 -> independent verifier
 -> VerificationResult
 -> human/governance decision

The remaining work therefore shifted to the canonical node worker and controlled Docker acceptance.

---

4. Reconciled old PR #34 without force-pushing, then accepted its supersession

PR #34 was initially on stale head:

9ac6c09d4db06dc7c846d319e76624fbf1eaaa0f

Its 12 changed paths were verified to be absent from then-current main, so the change remained cleanly additive.

A normal two-parent synchronization merge was constructed:

• previous PR head as one parent;
• current main as the other parent;
• current main tree preserved;
• exact node blobs overlaid;
• no force push.

Temporary synchronized head:

10a1885505859abef266d66839c90c0041adcf8a

Both checks passed on that exact head:

• IDKMesh Node CI 33182791204 — success;
• Phase 0 schema check 33182791209 — success.

Immediately afterward, concurrent repository work closed #34 without merge and opened a cleaner convergence PR #91. Because #91 started from a newer main and intentionally superseded #34, #34 was not reopened.

---

5. PR #91 became the canonical real-worker convergence path

PR #91:

Converge canonical WorkUnit v0.2 node backend onto current main

Branch:

integration/canonical-node-current

It keeps one canonical contract family:

WorkUnit v0.2
 -> Node Execution Binding v0.1
 -> idkmesh-node
 -> ResultManifest v0.1
 -> independent VerificationResult v0.1
 -> human/governance integration

The worker never treats its own successful execution as acceptance.

Initial important safety delta: untracked artifacts

The convergence work identified a real evidence-completeness problem:

• Git patches capture tracked changes;
• untracked outputs can exist outside that patch;
• a successful worker must not silently omit part of its candidate output.

PR #91 therefore fails closed on any untracked task artifact until a typed/size-bounded packaging protocol exists.

It records:

• untracked_file_count;
• untracked_paths;
• policy violations.

---

6. Independent pre-Docker source review found additional blocking evidence-integrity gaps

Before asking a community contributor to run Docker acceptance, the worker source was independently reviewed rather than assuming green unit CI proved containment.

The review found four important issues.

Finding A — truncated candidate patch could still report success

The earlier runner bounded changes.patch by truncating it, but a truncated candidate could still report status: succeeded.

That is an evidence-completeness failure: the canonical candidate artifact is incomplete.

Fix: patch truncation now creates an output-policy violation and the attempt fails closed. A truncated patch is diagnostic evidence only.

Finding B — task-writable .git metadata was later trusted by the host

The earlier design mounted the checkout—including .git—read/write into the task container, then used that same Git metadata for host git diff/git ls-files evidence.

A task could therefore alter refs/index/config/control metadata and influence the measurement of its own output.

Fix:

• real Git directory stored outside task-writable /workspace;
• mounted read-only at /git-meta for task-side Git reads;
• host Git result capture uses explicit trusted --git-dir and --work-tree arguments;
• host Git HOME/XDG isolated;
• system/global Git config disabled;
• inherited GIT_* variables removed;
• empty init template used;
• task-visible .git pointer tampering detected and fails closed.

This turns Git metadata into evaluator-controlled state rather than candidate-controlled state.

Finding C — .gitignore could hide untracked output

The earlier untracked scan used standard ignore behavior, which meant a task output matching .gitignore could disappear from evidence.

Fix: untracked result capture intentionally does not use --exclude-standard. Ignored files are still task outputs and are still observed/fail closed.

Finding D — image tag and wall-time provenance were not strong enough

Two reproducibility/resource issues remained:

1. allowlisted tags such as python:3.12-alpine are mutable;
2. budget.wall_seconds constrained the container timeout but not necessarily source preparation/result capture.

These were fixed before the Docker gate was frozen.

---

7. Runtime image is now bound to immutable evidence

The configured allowlisted tag is treated only as a routing/configuration selector.

The controlled host must preload it. The node then requires Docker inspection to provide:

1. immutable local image ID: sha256:<64 hex>;
2. matching immutable repository digest for the configured repository, e.g. python@sha256:<64 hex>.

A locally retagged/unresolved image without matching repository-digest evidence fails closed.

Docker runs by the resolved image ID, not the mutable tag.

The ResultManifest/provenance retains:

• configured_container_image;
• resolved_container_image_id;
• resolved_container_repo_digest;
• repository digest in runtime provenance.

The worker performs no implicit pull during task execution.

---

8. WorkUnit wall time is now a cross-phase bound

budget.wall_seconds is required and carried into the parsed WorkUnit.

The worker uses a single attempt deadline spanning:

• immutable image resolution;
• source preparation/fetch/checkout;
• task-container execution;
• bounded host-side Git evidence capture.

A small bounded tail is reserved for evidence capture so the task cannot consume every remaining second and prevent the worker from recording why it stopped.

Measured whole-attempt overruns become runtime-policy violations.

Timeout cleanup (docker rm -f) is bounded containment cleanup, not extra task authority.

---

9. Tests now encode the discovered assumptions as explicit invariants

The node test suite now covers, among other cases:

• Docker network none, read-only root, dropped capabilities, no-new-privileges, resource limits;
• external /git-meta read-only mount;
• removal of inherited Git configuration;
• explicit trusted host Git metadata/work-tree addressing;
• .git pointer tampering;
• ignored untracked output detection;
• untracked-artifact fail-closed behavior;
• tracked path policy;
• candidate-patch truncation failure;
• immutable image ID + matching repository digest parsing;
• locally retagged/no-repository-digest rejection;
• preloaded-image requirement;
• WorkUnit wall-budget handling.

---

10. Negative CI evidence was retained and used

A hardening head 5567dd126ae4ef45a90a852c7f66361ff89703ac produced:

• Phase 0 schema check 33183750657 — success;
• IDKMesh Node CI 33183750664 — failure.

The Node CI failure was isolated to the test harness, not a production-policy relaxation:

• a test passed the synthetic absolute deadline 10**12 into a real Python subprocess;
• the OS time conversion raised OverflowError: timestamp too large to convert to C _PyTime_t.

The test was corrected to use a realistic time.monotonic() + 60 deadline.

This failed run remains useful evidence because it demonstrates that new safety logic was actually exercised rather than merely documented.

---

11. Executable hardening became green

After correcting the test fixture, executable code head:

cb9279c86cd30a2201267319b623206e153d7239

passed:

• IDKMesh Node CI 33183837389 — success;
• Phase 0 schema check 33183837441 — success.

Then node/README.md was updated to accurately describe the implemented immutable-image and whole-attempt evidence rules.

That documentation-only commit moved the PR head, so the previous green evidence was not silently carried forward. Exact-head CI was checked again.

---

12. Final frozen PR #91 candidate for controlled Docker acceptance

Final head at the end of this turn:

d638a2f78e4a89353b98e91052233e365f56f90a

The only delta from cb927... is node/README.md, but the exact final head has its own complete green checks:

• IDKMesh Node CI — run 33183974768 — success;
• Phase 0 schema check — run 33183974817 — success.

PR #91 remains draft intentionally. It is not considered runtime-ready merely because unit/contract CI is green.

---

13. Issue #37 is now the precise independent runtime gate

Issue #37 was rewritten as:

Acceptance: run PR #91 idkmesh-node on a controlled Docker host

It is frozen to exact head:

d638a2f78e4a89353b98e91052233e365f56f90a

It records the exact green CI runs and requires a controlled-host positive smoke plus five negative runtime checks:

Positive

• preload and inspect python:3.12-alpine;
• record local image ID and matching repository digest;
• run canonical node smoke;
• verify ResultManifest, source/image provenance, path evidence, artifact/log hashes, sandbox flags, no untracked/policy violations, no self-acceptance.

Negative A — out-of-scope tracked path

Must fail closed and record path violation.

Negative B — ignored untracked output

Must still be observed despite .gitignore and fail closed.

Negative C — Git metadata tampering

Must not change real /git-meta; host evidence remains anchored to trusted metadata; pointer tampering is recorded and fails.

Negative D — oversized candidate patch

patch_truncated=1 must be a failure; truncated patch is diagnostic only.

Negative E — unresolved/locally retagged image

Missing preloaded image or missing matching repository digest must fail closed; no implicit task-time pull.

No Docker runtime acceptance was claimed in this chat because the available execution environment is not the explicitly controlled Docker host required by #37.

Safety / convergence decisions preserved

• No duplicate orchestrator was kept open after equivalent work landed.
• No force push was used while reconciling the old node branch.
• Closed/unmerged PR #34 was not reopened once cleaner #91 existed.
• Candidate evidence cannot omit untracked or oversized tracked output while reporting success.
• Candidate code cannot control the Git metadata used by host evidence capture.
• Host Git configuration is isolated from untrusted repository attributes/config triggers.
• Runtime image evidence is immutable and execution uses the resolved image ID.
• Whole-attempt wall budget covers source/runtime/evidence phases.
• No Docker acceptance was claimed without a controlled host.
• Acceptance evidence is bound to an exact PR head.
• Movement of base main alone does not invalidate a frozen candidate; changing the candidate does.
• Worker success remains candidate evidence, not acceptance.
• No autonomous merge authority was added.
• PR #91 remains draft until independent runtime evidence exists.
• Repository-admin main branch protection remains a separate unresolved safety requirement.

---

Community impact

This turn turned a vague “run Docker sometime” milestone into a high-value, bounded community contribution.

A contributor with a controlled Docker host now has:

• one exact candidate SHA;
• exact green CI identifiers;
• a positive procedure;
• five falsification-oriented negative tests;
• explicit image/source/evidence provenance requirements;
• clear acceptance semantics.

That is more useful for community growth than opening additional competing worker/orchestrator designs, because the task has a concrete definition of success and produces inspectable evidence the next contributor can build on.

---

Next action

The highest-value next action is independent controlled-host Docker evidence for #37 against:

d638a2f78e4a89353b98e91052233e365f56f90a

After #37 passes on the unchanged head:

real node
 -> ResultManifest
 -> independent verifier
 -> VerificationResult
 -> human decision

Then connect idkmesh-node behind the already-landed two-attempt coordinator and repeat the same evidence discipline with two real attempts.
