C1-A01 (P2). `resolveJobOperation` resolved operation names through `OPERATION_LOOKUP.get(value)`. `Map.prototype.get` is looked up at call time, so a hostile replacement installed after module initialization could map any requested name onto a repair-authorizable one. Reproduced from the parent baseline: with `Map.prototype.get` returning `source.edit`, a valid repair-job envelope resolved `merge` to `source.edit` and produced ALLOW_ONCE / WITHIN_JOB_ENVELOPE with an execution permit issued. The same corruption applied to `auto_merge.enable` and to unmodeled names such as `shell.exec`. Remove the Map lookup entirely. Resolution is now an exact membership test against the existing frozen vocabularies via `containsValue`, which touches no prototype method, and the value returned on a hit is the caller's own string rather than one produced by a container. The resolver can therefore return only the exact requested name when it is modeled, or UNKNOWN_JOB_OPERATION. No runtime mechanism can substitute one operation name for another. Adds focused adversarial regression coverage under poisoned `Map.prototype.get`, restoring the captured descriptor in a finally block: merge stays merge, auto_merge.enable stays auto_merge.enable, shell.exec stays unknown, source.edit stays source.edit, merge cannot reach ALLOW_ONCE, unknown cannot reach ALLOW_ONCE, and a legitimate source.edit still authorizes byte-identically to its unpoisoned baseline.

C1-A01 — Harden operation resolution against prototype poisoning
C1-A02 (P2): `OperatorMergeAuthorization` / `operatorMergeAuthorizes` comments and the C1 architecture document claimed stronger guarantees than the implementation proved. The predicate proves structural binding only: readable required fields, a literal `singleUse === true` marker, and exact repository, pull-request, and current-HEAD SHA equality. It does not prove operator origin, human identity, authentication, trusted minting, signature or possession, uniqueness, one-time consumption, or replay prevention. A plain caller-written object literal passes, and the same record passes repeatedly because C1 has no consumed-capability store. Correct the claims without changing executable authorization semantics. A `true` result is now documented as a necessary binding check, not sufficient proof that a merge is operator-authorized; the future trusted operator boundary / merge broker remains responsible for authenticated operator origin, trusted minting provenance, and one-time consumption. Two focused tests pin the limitation so the documentation cannot drift from the implementation. Ordinary repair-job merge authority is unchanged: still OPERATOR_REQUIRED, mayExecuteOnce=false, permit=null. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
External review of PR #17 (Codex and CodeRabbit, one root cause) found that the repaired C1-A02 text still described `MergeTarget.currentHeadSha` as if C1 observed an authoritative live repository HEAD. It does not. `operatorMergeAuthorizes` performs no repository read, no GitHub API call, no adapter call, and no network access. It compares `authorization.headSha` against the caller-supplied `target.currentHeadSha` and nothing else, so the binding is only ever as fresh and as authoritative as the target handed to it. Correct the claims without changing executable authorization semantics: - `MergeTarget` fields are documented as caller-supplied input; the "repository's HEAD now, supplied by a trusted adapter" wording is gone. - The predicate's guarantee is stated against the supplied target, with target authoritativeness and freshness listed as not proved. - "a new HEAD requires a new operator decision" is removed. C1 requires only a newly matching candidate record; it cannot tell a fresh human decision from the same untrusted caller assembling another literal. - The architecture document gains an explicit list of what the future trusted Merge Broker must do, including obtaining the authoritative pull-request HEAD immediately before merge and consuming the capability atomically. One test title repeated the same false repository-observation claim and is corrected; assertions are unchanged. Ordinary repair-job merge authority remains OPERATOR_REQUIRED, mayExecuteOnce=false, permit=null. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…laims C1-A02 — Clarify operator merge authority guarantees
`readList` obtained each authorization-list entry with an ordinary indexed read, which walks the prototype chain. At a sparse hole that resolved whatever a custom array prototype — or `Array.prototype` itself — carried at that numeric key, so a value the operator never supplied could enter the trusted `RepairJobAuthorization` snapshot as an authorized path or command class and reach `ALLOW_ONCE` with an `ExecutionPermit` bound to the fabricated operand. Entries are now obtained through `readOwnElement`, which gates the read behind the module's already-captured `Object.hasOwn` and reports absence with a module-private sentinel rather than collapsing it into `undefined`, so the list refuses a missing element itself instead of relying on the element reader. A sparse hole rejects the whole list: never skipped, defaulted, or filled from the prototype chain. Dense own lists are unaffected. The guarantee is documented at the strength the code proves. It holds for any array whose own-property introspection is truthful; a Proxy defines the observable result of both the own check and the read, so one that misreports ownership can still pass an inherited value through. That widens nothing — such a caller can supply the same value as a dense own element — and the comment and architecture text now say so rather than claiming an atomic observation. The sentinel is a bare object literal, so it adds no call into a mutable global and keeps the module's captured-intrinsic discipline. Merge stays OPERATOR_REQUIRED, auto-merge stays DENY, and C1-A01 and C1-A02 are untouched. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

There was a problem hiding this comment.
When configuration mixes a short branch name with its fully qualified form, such as repairBranch: "main" and protectedParentRef: "refs/heads/main", this exact-string check accepts the envelope even though Git resolves both names to refs/heads/main (confirmed here with git rev-parse --symbolic-full-name; see Git's refname resolution rules). A matching repair.push request therefore passes the later exact comparisons and can update the protected branch, defeating the quarantine invariant; validate/canonicalize both refs before checking that they differ.

When the repair worktree already contains staged changes to an unauthorized path—for example, left by initialization or produced as a side effect of an allowed verification command—this branch authorizes repair.commit solely from the worktree and ref. The resulting permit likewise contains no path set, tree ID, or index ID, so an executor cannot distinguish a commit containing only authorizedPaths from one that also commits arbitrary files. Bind authorization to the exact staged tree/diff and reject any changed path outside the job envelope before issuing the permit.

When the trusted job is a mutable plain object, a getter or Proxy trap in the untrusted request runs during readJobOperation before the job is snapshotted. For example, a repair.push request getter can change job.repairBranch to the original protected ref and change job.protectedParentRef to another valid ref before returning the original protected ref; readRepairJobAuthorization then accepts the altered envelope and the evaluator issues an ALLOW_ONCE permit to push the protected branch. Read and freeze the trusted job snapshot before performing any request property access so request-side effects cannot redefine the authority being checked.

When a future merge broker supplies a mutable authoritative MergeTarget and the untrusted authorization is a getter-bearing object or Proxy, reading the authorization first lets it mutate target.currentHeadSha (or the repository/PR fields) before those fields are captured. A candidate for a stale SHA can therefore rewrite the target to that SHA and make operatorMergeAuthorizes return true even though it did not match the target as supplied; capture the target snapshot before performing any candidate-controlled property access.

When a repair.push request has an own force getter that throws—or explicitly supplies force: undefined—readOwnProperty collapses that state to undefined, and this condition treats it as if the property were absent. An otherwise valid request therefore receives ALLOW_ONCE even though the evaluator could not establish that the push is non-forced, contrary to the documented fail-closed behavior; preserve whether the property was absent versus unreadable and treat unreadable or explicitly undefined values as forced.

There was a problem hiding this comment.
When a future executor passes a mutable permit/request (including the hostile getters and Proxies this API explicitly accepts), permitAuthorizes can return true after observing authorized operands, but it discards the freshly frozen decision.permit and exposes only a boolean. A subsequent read from the original permit or request can then yield different operands—for example, a push ref getter can report the repair branch during verification and the protected parent during execution—so the executor has no stable checked value to consume. Return the re-derived frozen permit (or otherwise execute against that snapshot) rather than requiring callers to reuse the mutable inputs after this check.

Purpose
C1 establishes the pure TypeScript repair-job authority boundary for the future AgentBridge Cockpit.
It models:
C1 performs no filesystem, Git, GitHub, subprocess, network, persistence, workflow-state, authentication, provider runtime, or merge execution.
The historical V1 read-only boundary remains preserved. Future write authority is explicitly job-scoped and is not granted by this PR itself.
Status
DRAFT — FRESH C1 PARENT AUDIT CLEAN AFTER PR #21 INTEGRATION.
This PR is the protected C1 parent integration branch.
Current protected-parent HEAD:
dd1bdd494f37d0cf42ea79fd7a9eb41d04a17bbeFresh independent parent audit result:
PASS
Historical findings on CURRENT HEAD:
Current findings:
NONE — no blocking CURRENT P0/P1/P2/P3 findings.
The fresh independent auditor reverified the integrated parent HEAD after the C1-A04 ref-alias repair (stacked validation PR #21) was operator-merged into this protected parent with a merge commit, in addition to the three earlier stacked repairs (A01, A02, A03).
Known non-blocking deferred items:
docs/architecture/C1-repair-job-authority.md: the sentence stating that Git resolvesmain/heads/main/refs/heads/mainto one and the same ref reads too absolutely; the adjacent paragraph already states repository-state-dependent resolution. Deferred for bounded documentation cleanup.Quarantine rule
Finding
→ verify against CURRENT C1 HEAD
→ isolated repair branch/worktree
→ bounded repair
→ independent validation
→ commit + normal push
→ stacked validation PR targeting this protected parent
→ CI + independent external review
→ policy/evidence gate
→ READY_FOR_MERGE
→ operator merge decision
→ re-audit parent NEW HEAD
The protected parent is an integration quarantine boundary.
No implementing agent is its own sole validator.
Unvalidated agent-generated repairs must never be placed directly into this protected parent.
Merge boundary
MERGE IS OPERATOR-ONLY.
No Claude, Codex, CodeRabbit, ChatGPT, or other AI is authorized to merge this PR or any stacked repair PR.
No AI may enable auto-merge.
Maximum autonomous state is:
READY_FOR_MERGE
After READY_FOR_MERGE, the workflow must stop for explicit operator decision.
C1 ordinary-job authorization continues to enforce:
merge→OPERATOR_REQUIRED/MERGE_IS_OPERATOR_ONLY/permit = nullauto_merge.enable→DENY/OPERATION_FORBIDDEN/permit = nulloperatorMergeAuthorizesis only a pure structural predicate. It does not prove human origin, authentication, trusted minting, uniqueness, one-time consumption, replay prevention, live target freshness, or merge authority.A future trusted Merge Capability Broker must separately authenticate the operator, bind authorization to exact repository + PR + authoritative live HEAD, atomically consume the single-use capability, reject HEAD movement, and merge only after all gates pass.
C1 implements none of those broker functions.

Historical repair disposition
C1-A01 — P2 — FIXED
Original defect: mutable
Mapprototype lookup could corrupt operation resolution under hostile prototype mutation.Validated repair entered through an isolated repair branch and stacked validation PR #16, then was merged into the protected parent by the operator.
Current implementation no longer depends on mutable
Map.prototypelookup for operation resolution.C1-A02 — P2 — FIXED
Original defect: documentation overstated what
OperatorMergeAuthorization/operatorMergeAuthorizesproved.Validated repair entered through stacked validation PR #17 and was merged into the protected parent by the operator.
Current documentation explicitly states that the predicate proves structural field matching only and enumerates the functions reserved for a future trusted Merge Capability Broker.
C1-A03 — P2 — FIXED
Original defect: ordinary indexed reads of sparse authorization lists could walk the prototype chain and convert inherited numeric properties into authorization scope, including a proven
DENY→ALLOW_ONCEauthority change with a non-null permit.Validated repair entered through stacked validation PR #19 and was merged into the protected parent by the operator.
Current authorization-list handling requires own elements through captured own-property introspection, rejects sparse holes all-or-nothing, and preserves the documented hostile-Proxy claim boundary without overstating provenance guarantees.
C1-A04 — FIXED
Original defect: a Git-equivalent protected/repair ref alias (
main,heads/main,refs/heads/mainnaming one ref) could separate a repair branch from the protected parent by string inequality, letting a mutating operation produce anExecutionPermitwhose ref denotes the protected branch.Validated repair entered through stacked validation PR #21 and was merged into the protected parent by the operator with a merge commit.
Current implementation narrows every job and operation ref through one canonical
refs/heads/<name>spelling and refuses ASCII-case collisions at configuration, so ref separation is separation of canonical ref names rather than of strings. Repository-resolved residues (symbolic-ref chains, filesystem case identity, effective worktree HEAD, push source/destination, change-request source/target) are documented as fail-closed obligations of the later trusted repository/Git execution boundary, not as V1 defects.Current scope
Exactly 10 changed files, 6321 additions, 0 deletions relative to the PR base.
No dependency,
package.json,package-lock.json, CI,tsconfig, eslint, or vitest configuration changes.Changed files remain limited to the C1 domain model, tests, additive domain exports, and C1 architecture documentation:

PR #14 remains DRAFT until this metadata update is independently re-read and confirmed truthful.
Only after that confirmation may PR #14 enter the separate Ready gate.
Even if every gate passes, the maximum state is READY_FOR_MERGE and the workflow must stop for the operator's explicit merge decision.
