PR 022 P3: Qualify process transport exchange outcomes

[LogicDuke]

Purpose

Child stacked validation PR for the CURRENT Codex P3 finding on parent stacked
PR #22.

This repair is quarantined beneath PR #22 and MUST NOT target PR #10 or main
directly.

Finding

Codex identified a residual P3 contract overclaim in PR #22: documentation
still materially promised an AgentExchange on every
validation/spawn/I/O/timeout/cancellation/overflow/termination/close path even
though the post-spawn hardening-failure path performs bounded
termination/cleanup and rejects rather than resolving an AgentExchange.

Classification:

CURRENT P3

Repair

Documentation/JSDoc only.

Changed files exactly:

• docs/architecture/010-commander-claude-bridge.md
• src/adapters/process-transport.ts

The repair:

• scopes the resolution guarantee to defined handled exchange outcomes;
• preserves deliberate hardening-failure rejection;
• removes residual every-path totality;
• avoids global never-reject and synchronous-no-throw claims;
• avoids the rejected provider-neutral reports terminology;
• preserves the AgentExchange / AgentReport architectural distinction;
• makes no executable runtime change;
• makes no test change.

Independent validation

A fresh independent validator reproduced the original Codex P3 and reviewed the
final candidate byte-for-byte.

PASS evidence includes:

• executable runtime code unchanged;
• tests unchanged;
• every-path resolution overclaim removed;
• category list does not recreate totality;
• exchange outcomes terminology verified;
• AgentExchange / AgentReport boundary verified;
• hardening rejection accurately documented;
• universal synchronous-no-throw claim absent;
• global never-reject claim absent;
• unconditional termination-success claim absent;
• focused hardening tests passed;
• complete process-transport tests passed;
• full npm test passed;
• typecheck passed;
• lint passed;
• build passed;
• git diff --check passed;
• architecture unchanged;
• AgentBridge V1 authority boundary unchanged.

Quarantine requirement

Do not merge this child PR merely because an implementing or validating agent
reported success.

Required before merge upward into PR #22:

• verify exact base/head/SHA;
• CI/checks on exact child HEAD;
• independent GitHub review;
• classify every review finding against CURRENT child HEAD;
• policy/evidence gate PASS;
• human merge using CREATE A MERGE COMMIT only.

After integration, PR #22 must be re-audited at its new HEAD.

Summary by CodeRabbit

• Documentation
  • Clarified process invocation outcomes and error handling.
  • Defined operational failures now resolve to standardized exchange results.
  • Failures establishing required child-dispatch protections reject after cleanup and remain distinct from spawn failures.
  • Unexpected programmer or security-boundary defects continue to propagate instead of being converted into failure codes.

📝 Walkthrough

Walkthrough

The PR updates architecture and API documentation for process transport failure handling. It distinguishes defined operational outcomes from post-spawn child-dispatch hardening rejections and confirms that undefined defects propagate.

Changes

Transport outcome contract

Layer / File(s)	Summary
Outcome and rejection semantics docs/architecture/010-commander-claude-bridge.md, src/adapters/process-transport.ts	The documentation defines frozen operational outcomes, fail-closed hardening rejections after cleanup, and propagation of programmer or security-boundary defects.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: ⚪ Minimal · up to 7378f

The change narrows the documented process-transport exchange guarantees to match existing behavior without changing runtime execution, tests, or architecture; no actionable merge-blocking risk remains beyond normal checks and review.

Poem

I’m a rabbit with docs in my burrow,
Outcomes stay frozen, clear and narrow.
Hardening fails? Reject after care.
Unknown defects travel bare.
Thump! The transport rules are now there.
