feat(lab): CL-10 public evidence trust core - #1628
Conversation
📝 WalkthroughWalkthroughChangesPublic evidence export
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR adds public bundle signing, canonicalization, validation, and storage behavior, but current code can reject otherwise valid signed bundles on different locales and can throw unexpectedly for malformed observation data instead of returning the documented non-exportable result. These bounded correctness and integration risks should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

This is thoughtfully fail-closed in the important places: local signing validates authority and privacy before creating publisher-key state ( There is no CodeRabbit finding to adjudicate — its review was skipped because this PR is draft. This is a 21-file, +2,630-line cryptographic, privacy, and durable-filesystem feature, not a narrowly scoped release fix. It is currently draft, its head is behind current DISPOSITION: DEFER |
Rebased onto current dev with the reviewed public evidence trust core, consumer durability recovery, sparse-array JCS hardening, and required Windows publisher-key ACL hardening.

Inline comments:
In `@src/lab/public/bundle.ts`:
- Around line 29-38: Export the existing assertUtcDay validator from
validate.ts, remove the duplicate utcDay implementation in bundle.ts, and update
the bundle’s createdDayUtc call site to use assertUtcDay. Preserve the existing
validation behavior and rely on the shared validator’s canonical error handling
and string checks.
- Around line 133-137: Replace the locale-sensitive comparators in the record
and artifact sorting within the bundle construction flow with deterministic
code-unit ordering, preserving ascending canonical order used by
canonicalPublicEvidenceContent and bundle identity generation. Add a focused
regression test near the existing public bundle tests that constructs a known
multi-record bundle and asserts its fixed bundleDigest.
In `@src/lab/public/private-file.ts`:
- Around line 109-134: Update cleanupStalePrivateFileStagesInDir to accept an
optional stage-name prefix and filter directory entries before calling
shouldReclaimPrivateFileStage. Have cleanupStalePrivateFileStages pass
staleTempPrefix(finalPath), while preserving the unfiltered behavior when no
prefix is provided for maintenance callers.
In `@src/lab/public/project.ts`:
- Around line 88-121: Update projectPublicEvidenceRecord so unrepresentable JCS
input, including lone UTF-16 surrogates, returns the existing not_exportable
result without swallowing PROJECTOR_INVARIANT_ERROR_CODES; either narrowly
handle the canonicalizer TypeError or validate projected public identifiers
before both publicEvidenceId calls, preferably the latter. Add a focused
regression test covering a surface value containing a lone surrogate and assert
the not_exportable outcome.
In `@src/lab/public/signature.ts`:
- Around line 55-69: Update requirePublisherKeyAcl to capture any error thrown
by hardenSecretPath and preserve it as the cause when throwing
PublicEvidenceValidationError, while retaining the existing stable error message
and fail-closed behavior.
In `@src/lab/public/storage.ts`:
- Line 68: Extend tests/lab-private-file-consumer-recovery.test.ts with a
focused round-trip test that stores a public evidence bundle, reads it back via
readPublicEvidenceBundle, and asserts the returned bundleId to cover the
trailing-newline serialization path in parseStrictPublicJson.
In `@src/lab/public/time.ts`:
- Around line 4-18: Update publicUtcDay to reject timestamps whose UTC year
falls outside the four-digit range 0000–9999, in addition to the existing
validity checks, before calling toISOString(). Preserve the
public_selection_time validation error for all out-of-range inputs so
expanded-year output cannot reach the slicing logic.
In `@tests/lab-private-file-durability.test.ts`:
- Line 14: Remove the setCommitFault cast alias and call
setPrivateFileCommitFaultForTests directly at
tests/lab-private-file-durability.test.ts lines 34, 50, 67, and 89, preserving
PrivateFileCommitFault type enforcement from private-file.ts. In
tests/lab-private-file-consumer-recovery.test.ts lines 56 and 67, replace bare
throw assertions with a matcher requiring directory-sync or durability text so
the parent_directory_sync fault is verified.
In `@tests/lab-public-core-contract.test.ts`:
- Around line 106-117: Extend the strict JSON bounds test around
parseStrictPublicJson with acceptance assertions for each maximum legal
boundary: nesting depth 8, an array containing 512 elements, an object
containing 64 keys, and input of exactly 2 MiB. Confirm the parser’s return type
and assert successful parsing using the appropriate result shape, while
preserving the existing rejection assertions for values beyond each limit.
In `@tests/lab-public-file-safety.test.ts`:
- Around line 19-36: Add a focused test beside the existing symlink case for an
unrelated hard link: create the target with linkSync under a non-stage name,
call readPrivateRegularFile with the same safety options, and assert it throws
PublicEvidenceValidationError. Import linkSync from node:fs and preserve cleanup
and platform handling consistent with the surrounding tests.

Add a fixed-digest test for canonical artifact ordering. tests/lab-public-core-contract.test.ts:92-112 covers multiple records, but no test covers multiple artifacts with a fixed bundleDigest. Add a multi-artifact case that asserts sorted artifactId values and the resulting digest.

Pass records in reverse order.
Lines 102 and 108-112 use the same record order. The test does not prove canonical sorting.
Pass [second, first]. Keep the expected record IDs and digest in canonical order. This makes a caller-order regression fail.
As per path instructions, “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”

Closing this as an owner decision, not a quality judgment on the work. I reviewed the Compatibility Lab integration on
opencodex is a provider proxy. A user who points at one model and goes should not be executing evidence-collection code on their request path, and should not have to. What happens next: feature work on the CL line is frozen until a decoupling patch lands that enforces the boundary — Lab and routing-compatibility code must execute only when routing profiles are actually configured. I am taking that patch on directly. Once the boundary is in place and enforced by a regression test, the public-evidence work in this PR can be reopened or resubmitted on top of it. Nothing here is lost: the branch and its history stay intact, and CL-01 through CL-09 remain on Apologies for the late intervention. This should have been caught before CL-09 merged; that gap is mine, not yours. |
