Summary

  • add SDK-first linked-test workspace contexts (source, genuinely empty isolated, and protected no-writeback snapshot) across single-item and batch execution
  • persist immutable command provenance, mark merge-unioned and malformed legacy commands untrusted, and fail closed unless the explicit trust policy is satisfied
  • distinguish requested and effective tracker/workspace context in receipts, classify trust refusals separately from test assertions, and keep acknowledgement foreground-only and non-executing
  • carry the behavior through CLI flags, SDK types, MCP/tool schemas, generated contracts, docs, static refusal ratchets, and full unit/integration coverage
  • retain the broader branch delivery: ESLint 10.9.0, complete GitHub issue-to-PM reconciliation, changelog evidence, and linked-test validation/configuration surfaces

Verification

  • node scripts/run-tests.mjs coverage: 563 files, 7,797 tests, exact 100% statements/branches/functions/lines with zero uncovered counts
  • pnpm lint: ESLint clean, 0 duplicate clones across 1,100 files, and complete static assurance clean
  • final pnpm quality:static against closed tracker state: all repository, contract, SDK parity, refusal, graph, and record-integrity gates pass
  • PM-linked sandbox runs: 37/37 batch-adapter tests, linked workspace integration, and 169/169 trust/config/validation tests pass
  • temporary Git/PM consumer: empty isolated cwd, protected snapshot with no source writeback, single-item runs, test-all snapshot override, and requested/effective receipt proof
  • pnpm audit --audit-level=low: no known vulnerabilities
  • tracked secret scan: clean
  • GitHub Dependabot, code-scanning, and secret-scanning open-alert inventories: 0/0/0
  • latest available pm-changelog 2026.8.17 installed; generated CHANGELOG.md is current

PM lineage

The three active continuation items are closed with resolution, expected/actual results, linked files/docs/tests, exact local evidence, append-only history, and v2026.8.23 targeting. There are zero in-progress PM items after releasing their claims.

Rollout

  • Existing locally-authored linked tests on the same source ref remain trusted by default.
  • Use workspace_context_mode: "isolated" for commands that must not see the source checkout and "snapshot" for disposable source copies with no writeback.
  • Foreign, malformed, legacy merge-unioned, or otherwise untrusted commands remain blocked unless project policy and the per-run override both consent; acknowledgement records trust without running commands.
  • Consumers of strict SDK or MCP schemas should regenerate adapters for the new context, provenance, acknowledgement, and refusal fields.

Summary by Sourcery

Harden linked-test execution by isolating workspace contexts and requiring explicit, auditable trust for commands introduced through merges or carrying invalid provenance.

New Features:

  • Add source, isolated, and snapshot workspace contexts for linked-test execution across single-item and batch workflows.
  • Add provenance-aware linked-test trust decisions with clone-local acknowledgements and explicit opt-in execution for untrusted commands.

Bug Fixes:

  • Prevent merged, foreign, malformed, and legacy-union linked commands from executing without satisfying the trust policy.
  • Preserve and report requested versus effective workspace context and classify trust refusals separately from test failures.

Enhancements:

  • Propagate workspace, provenance, trust, acknowledgement, and refusal contracts through the CLI, SDK, MCP schemas, generated contracts, validation, receipts, and merge handling.
  • Keep snapshot execution isolated from source writeback and make acknowledgement foreground-only and non-executing.

Build:

  • Update ESLint to version 10.9.0 and refresh the lockfile.

Documentation:

  • Document linked-test workspace modes, trust policy, acknowledgements, and merge safety behavior.

Tests:

  • Add comprehensive unit and integration coverage for workspace isolation, snapshot safety, provenance merging, trust decisions, acknowledgements, and contract propagation.

Chores:

  • Reconcile linked PM issue records and update changelog and release assurance surfaces.

Persist source/isolated/snapshot context, provenance, merge trust, dual consent, validation diagnostics, generated contracts, documentation, and full PM closeout. Update ESLint to 10.9.0 and reconcile GitHub issue tracking into the canonical PM backlog.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 8a5b1

This PR changes linked-test execution context and trust enforcement, but the current head can still launch commands during acknowledgement, reuse trust after execution-environment changes, and make validation or recovery disagree with actual execution. These are concrete safety and correctness risks at the merge boundary, so the PR is not merge-ready until fixed or explicitly accepted.

16013-16058: 🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Add a bulk trust-consent path for pm test-all. TestAllCommandOptions has no acknowledgeLinkedTests, and the batch path does not record clone-local consent. The foreground CLI path also drops allowUntrustedLinkedTests, although it exposes the flag. If bulk consent is required, add the option and forward both trust options through foreground and background execution.

Inline comments:
In `@src/cli/register-operations.ts`:
- Around line 891-902: Update the foreground test-all adapter in
runTestAllAction to forward workspaceContext, overrideLinkedWorkspaceContext,
and allowUntrustedLinkedTests in the options passed to runTestAll. Add CLI
adapter coverage verifying each option value is forwarded.
- Around line 966-969: Reject the combination of --background and
--acknowledge-linked-tests during test command validation, before
runBackgroundLinkedTests can launch commands; preserve acknowledgement behavior
for non-background execution and add a regression test covering the conflicting
flags.

In `@src/core/item/item-format.ts`:
- Around line 1188-1211: Update normalizeLinkedTestProvenance and the
linked-test trust evaluation so malformed provenance is distinguishable from
absent provenance; when provenance is present but fails validation,
resolveLinkedTestTrustFromLedger must not grant trusted “legacy” status.
Preserve legacy trust only for genuinely absent provenance.

In `@src/sdk/cli-contracts/tool-schema.ts`:
- Around line 1104-1107: Update the test contract’s mutuallyExclusive
configuration to place acknowledgeLinkedTests and run in the same exclusion
group, matching the rejection enforced by assertTestRunFlagUsage. Keep both
properties optional and preserve all existing exclusivity groups.

In `@src/sdk/lifecycle/create.ts`:
- Around line 2736-2741: Guard the attachLinkedTestProvenance flow so
resolveLinkedTestSourceRef is called only when tests.values?.length is non-zero
in src/sdk/lifecycle/create.ts (lines 2736-2741). Apply the same conditional
guard around testUpdates.values?.length in src/sdk/lifecycle/update.ts (lines
3231-3236); both sites require changes.

In `@src/sdk/merge/three-way.ts`:
- Around line 498-515: Update markMergedLinkedTest so linked tests without
provenance receive provenance identifying source_kind as merge_union instead of
being returned unchanged; preserve existing provenance fields and continue
normalizing already-provenanced entries.

In `@src/sdk/test/execution.ts`:
- Around line 2358-2359: Update the workspace context fields in the execution
context construction to preserve meaningful requested-versus-resolved semantics:
either remove requested_workspace_context_mode from the public serialized
contract, or populate it with the pre-override run-level workspace mode while
workspace_context_mode remains the resolved params.workspaceContextMode value.
Keep the existing pm-context pair behavior as the model.
- Around line 2331-2336: Update the isolated execution path around
workingDirectory and LinkedTestSandboxLayout so isolated commands run from a
dedicated empty sandbox directory rather than params.sourceWorkspaceRoot. Add
and create isolatedWorkspaceRoot alongside the snapshot root, select it for
workspaceContextMode === "isolated", and keep the existing source and snapshot
directory behavior unchanged.
- Around line 3336-3342: Update the provenance setup in runTest to resolve the
source ref using the same workspace-root logic as runLinkedTests, including
PM_SOURCE_WORKSPACE_ROOT with process.cwd() as fallback. Extract that root
resolution into a shared helper and pass the resolved root to
resolveLinkedTestSourceRef, ensuring both run paths use the same repository.
- Around line 2150-2176: Update seedLinkedTestWorkspaceSnapshot to exclude
ignored directories at every depth, not only when they are direct children of
sourceWorkspaceRoot. Apply the exclusion check to each path segment and include
nested node_modules, .git, .agents, and common build-output directories such as
dist and coverage while preserving the existing node_modules symlink handling.
- Around line 2490-2494: Add a dedicated trust-refusal category to the exported
LinkedTestFailureCategory type, regenerate the public SDK surface, include the
category in createEmptyFailureCategoryCounts, and update
resolveLinkedTestTrustPreflightResult to build refusals with it instead of
assertion_failure. Preserve genuine assertion failures and existing
aggregation/persistence behavior.

In `@src/sdk/test/parsers.ts`:
- Around line 719-733: Update the JSON workspace_context_mode parsing to pass
the read value through parseLinkedTestWorkspaceContextMode and store its
normalized result, replacing the direct raw-value membership check while
preserving the existing failure handling for invalid values.

Forward workspace and trust controls through batch execution while preserving requested and effective receipts. Isolate source workspaces, fail closed on malformed provenance, and ratchet refusal coverage. Close the canonical PM lineage with linked tests, documentation, and exact local verification evidence.

Inline comments:
In @.agents/pm/chores/pm-940mcx.toon:
- Around line 17-20: The structured tests and test_runs evidence must support
every gate claimed by actual_result and close_reason. Add PM-linked entries and
run records for full coverage, audit, and secret-scan verification alongside the
existing lint and typecheck records, ensuring each runnable verification is
linked to this PM item.

In @.agents/pm/history/pm-940mcx.jsonl:
- Around line 8-10: The close event records status before closure evidence is
present. Update the PM mutation workflow so metadata.resolution,
metadata.expected_result, and metadata.actual_result are recorded through a
supported update before op close, while preserving the append-only hash chain
and leaving the existing history file unchanged.

In `@CHANGELOG.md`:
- Around line 20-23: Move the cross-harness provenance adapters entry out from
under the Security section by placing it in its appropriate feature section, or
move the Security heading below that entry. Keep the linked-test security entry
under Security and ensure each changelog item is grouped under the correct
heading.

In `@src/sdk/cli-contracts/tool-schema.ts`:
- Line 1119: Update the mutual-exclusion contract around acknowledgeLinkedTests
to include background, and add the same combination check to CLI argument
validation so the command is rejected before building background execution
arguments.

In `@src/sdk/governance/validate.ts`:
- Around line 2903-2908: Update the linked-test validation flow around
resolveLinkedTestSourceRef to pass the workspace root resolved by
resolveLinkedTestSourceWorkspaceRoot, and import that helper if needed. Ensure
validation derives currentSourceRef from the same root used by the test runner,
including PM_SOURCE_WORKSPACE_ROOT overrides.
- Around line 2863-2885: Extract the command truncation logic from
summarizeCommandReferenceRow into a reusable summarizeCommandPreview(command)
helper, then call it directly from buildUntrustedLinkedTestRows instead of
formatting, splitting, and rejoining a row. Preserve the existing preview output
and confirm the nearby /* c8 ignore start */ coverage exclusion intentionally
includes this trust-diagnostic code.

In `@src/sdk/index.ts`:
- Around line 1255-1263: Update the SDK export block to include
resolveLinkedTestSourceWorkspaceRoot and attachLinkedTestMutationProvenance
alongside the existing linked-test provenance helpers, then regenerate
sdk/public-surface.json to reflect the expanded public API.

In `@src/sdk/test/trust.ts`:
- Around line 76-81: Update the catch block in the trust ledger loading flow so
the isFileMissingError(error) condition has meaningful behavior: retain
emptyTrustLedger() only for missing files, and propagate or record non-missing
errors as intended by the surrounding API. If all failures should return an
empty ledger, remove the redundant conditional and keep a single return path.
- Around line 203-259: Update resolveLinkedTestTrustFromLedger so the
acknowledged fingerprint check occurs before hasValidLinkedTestProvenance
rejects malformed provenance; return the existing acknowledged decision for
explicitly acknowledged entries, while preserving the invalid_provenance
decision for unacknowledged entries.

In `@src/types.ts`:
- Around line 1430-1431: Update the generated search tests in the scaffold flow
to populate the required testing settings instead of emitting an empty settings
object. Include both testing.record_results_to_items and
testing.allow_untrusted_linked_tests in each of the three generated fixtures,
preserving the PmSettings contract at runtime.
- Around line 343-355: Update the provenance type contract used by
normalizeLinkedTestProvenance and LinkedTest to include an explicit invalid
variant alongside local_mutation and merge_union, with the malformed payload
shape required by normalization. Replace the cast to LinkedTest["provenance"]
with the raw/validated provenance union, while preserving
resolveLinkedTestTrust’s invalid_provenance handling for malformed values.

Apply the same fix in `@tests/unit/sdk/test/linked-test-provenance-merge.spec.ts`
around lines 196 - 206: The test-side finding requires the same explicit invalid
provenance representation and sanitization.

In `@tests/integration/linked-test-context-trust.integration.spec.ts`:
- Around line 219-242: Extend the isolated-run assertions in the test around
runCli to verify its stdout does not expose source-only entries marker.txt,
nested/.git/secret, or nested/coverage/result.json. Keep the existing
execution-context and snapshot-only.txt checks unchanged, and assert the output
demonstrates none of those files are visible.

In `@tests/unit/sdk/test/linked-test-trust.spec.ts`:
- Around line 123-138: Update linkedTestTrustFingerprint in trust.ts to include
env_set, env_clear, and shared_host_safe in the hashed fingerprint input,
preserving existing bindings. Extend the linked-test trust test to verify that
changing each field produces a different fingerprint.

Acknowledged. All 25 inline findings were checked against exact head 64c333c: 24 were implemented or already fixed and the changelog classification was retained with canonical security-tag evidence. The repository's own static gate enforces 100% source/module, exported, and member docstring coverage and passed; CodeRabbit's touched-private-function metric uses a different scope. All hosted checks are green.

Acknowledged; the cross-layer review guide was useful. One stale detail is corrected on exact head: isolated mode runs in an empty disposable workspace, not the source checkout. Focused containment tests and the complete hosted matrix pass.

Acknowledged. The exact-head re-review request reached CodeRabbit but was rate-limited after the full hosted matrix passed. The earlier review's 25 threads are all resolved, reacted to, and answered with evidence.

Acknowledged. Sourcery's size-limit result is recorded as a provider limitation rather than approval; its separate review guide was cross-checked and the required repository and security gates passed.

Acknowledged. All 13 findings from this review were verified and answered inline: 12 fixes landed in 64c333c, while the changelog finding was declined because the canonical PM item has an explicit security tag and the package-owned generator is current.
