Owner

Summary

  • require important architecture, authority, identity, recovery, compatibility, public-API, and release decisions to have one canonical documentation owner
  • require current-versus-target posture, decision relationships, routing updates, and same-change refinement
  • distinguish durable architectural truth from GitHub delivery status and historical design evidence

Validation

  • git diff --check
  • Markdown lint on AGENTS.md

Docs-only contributor-policy change; no runtime behavior changed.

Summary by CodeRabbit

  • Documentation
    • Added guidance requiring important architecture and process decisions to be recorded in canonical documentation.
    • Clarified expectations for ownership, status, relationships, documentation routing, and ongoing updates.
    • Established that missing or outdated decision records are considered incomplete engineering work.

Walkthrough

AGENTS.md adds a “Durable Decision Discipline” section. It requires canonical records for durable decisions, explicit ownership and status, related-document links, documentation routing, and updates when decisions change. Missing or stale canonical documentation is defined as incomplete engineering work.

Changes

Durable Decision Discipline

Layer / File(s) Summary
Canonical decision documentation
AGENTS.md
The guidance requires durable architecture and process decisions to use one canonical document. It defines ownership, status, related-document links, documentation routing, implementation checklist separation, and updates when decisions evolve.

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

Merge Risk: 🟡 Moderate · up to 64f65

The policy currently gives conflicting guidance about where its canonical documentation belongs, which could lead contributors to update different sources and create inconsistent process instructions. Resolve the ownership and routing ambiguity before merging.

The policy assigns workflow policy to `docs/method/` and requires linking to a
canonical owner instead of copying a rule into several places. It then stated
itself, in full, in AGENTS.md -- violating both of its own rules in the act of
declaring them.

Moves the policy body to docs/method/durable-decisions.md, which the policy
names as the owner of workflow policy, and leaves AGENTS.md with a link plus
the agent-specific enforcement clause. Adds the new document to the AGENTS.md
router, as rule 3 requires. Records the canonical-owner assignments as a table
in the owning document.

Regression coverage in spec/audit-docs.spec.mjs asserts the policy rules appear
in exactly one document and that the router names the owner. Both assertions
fail at 64f6530.

Addresses review threads PRRT_kwDOSCKBn86bwuw6 and PRRT_kwDOSCKBn86bwvLA.
The policy names `docs/jim-component-ownership.md` as the owner of the
Jim/Jedit/Edict/Echo target ownership and causal model, while ARCHITECTURE.md
carried a competing normative "Target Ownership" section restating the same
component responsibilities in fewer words.

The two had already diverged, which is the concrete cost the policy exists to
prevent: ARCHITECTURE.md called `Jim.edict` "Jim's mind" while the owning
document calls `jim.core` "Jim's mind". Two documents, two names for one
component.

One rule in that section existed nowhere else -- the prohibition on Echo
carrying Jim vocabulary (`ReplaceRange` variant, rope intrinsic, `Buffer` or
`TextWindow` semantics, native Jim planner callback, `MutationPlan`,
caller-authored graph patch). It is target-ownership law, so it moves into the
owning document rather than being deleted with the duplicated prose.

ARCHITECTURE.md now routes to the owner and states no ownership rule of its
own. Regression coverage asserts the component rule appears only in the owning
document and that ARCHITECTURE.md links to it; the assertion fails at 64f6530.

# Sev Source File Issue Commit Outcome
1 P1 CodeRabbit + Codex (2 threads, 1 defect) AGENTS.md Policy assigns workflow policy to docs/method/ and forbids copying, then states itself in full in AGENTS.md ccb0f34b Fixed
2 P1 Codex ARCHITECTURE.md Target Ownership competes with the declared owner docs/jim-component-ownership.md 4b0f1e66 Fixed

Notes

On #1 — the policy violated two of its own rules while declaring them: rule 1 (workflow policy belongs to docs/method/) and rule 4 (link, do not copy). Body moved to docs/method/durable-decisions.md; AGENTS.md keeps a link and the agent-specific enforcement clause; the router is updated per rule 3.

On #2, one correction to the finding. The section was not purely duplicative. The prohibition on Echo carrying Jim vocabulary — no ReplaceRange variant, rope intrinsic, Buffer/TextWindow semantics, native Jim planner callback, MutationPlan, or caller-authored graph patch — appeared only in ARCHITECTURE.md, with zero occurrences in the owning document. Replacing the section with a link as written would have silently dropped a normative rule. It moved into the owner instead.

Divergence found while verifying. The two documents had already drifted: ARCHITECTURE.md called Jim.edict "Jim's mind"; docs/jim-component-ownership.md:39 calls jim.core "Jim's mind". Two documents, two names for one component — the exact failure this policy exists to prevent, and evidence the routing fix is the right call.

Verification

Regression coverage added to spec/audit-docs.spec.mjs (3 assertions). All three fail at 64f65307 and pass at this head.

npm run check exit 0 — 797 tests, 785 pass, 0 fail, 12 intentional skips; native suites green; quality gate reports no regressions.

Process note

My first local verification reported a tsc failure in src/app/title-camera-session.ts:380. That was invalid — my node_modules was installed from a different branch's lockfile. package.json and package-lock.json genuinely differ between this branch and #304. After npm ci the tree compiles clean, matching CI. Recording it so the false alarm is not rediscovered.

flyingrobots dismissed coderabbitai[bot]’s stale review September 8, 2026 03:21

Stale: this review is from 2026-08-24 and the branch has since been brought up to date with main (35 commits). No unresolved review threads remain on the PR. Conflicts in spec/audit-docs.spec.mjs resolved by honouring main's removal of the tool-sniffing logo audit while keeping this PR's durable-decision tests. npm run check: 869 tests, 857 pass, 0 fail, quality regressions none.
