Isolate SDK linked tests and preserve multi-tracker merge fences - #1322
Merged
Merged
Conversation
Add an opt-in linked-test context mode that omits PM_PATH only for disposable workspaces, while keeping trust checks and PM_GLOBAL_PATH isolation. This lets package acceptance tests create independent SDK tracker roots. Reconcile the active tracker merge block without deleting sibling mappings and make strict health detect a missing or drifted fence. Cover mixed legacy fences, truncated blocks, root-mounted trackers, and nested installs. Close the two tracked issues with test evidence, add the newly reported package scan defect to PM, and regenerate the changelog with pm-changelog.

Merge Risk: 🔵 Low · up to The self-isolating test example does not provide the promised environment, and a missing tracker fence can receive the wrong diagnostic. Both should be corrected, but neither prevents merging with owner awareness. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new controls improve isolation and preserve merge mappings during ordinary concurrent tracker updates. One recovery case remains risky: repairing an unfinished merge-fence block can erase unrelated Git attributes. Its impact depends on encountering an already malformed file. Retained concerns

the tracker’s exact generated patterns, rather than a broad root prefix that can
claim nested trackers’ fences. Pass the relevant patterns at each call site,
including the patterns built from relativeRoot and typeFolders, so parent

Match managed blocks to exact tracker patterns while retaining legacy direct type-folder drift diagnostics. Serialize shared .gitattributes reconciliation through a Git-directory lock and publish it atomically so simultaneous tracker refreshes cannot lose each other’s mappings. Cover ancestor and descendant trackers, extension exclusions, and concurrent refreshes. Record the review regression and complete verification in pm-kynkl8.

In @docs/TESTING.md:
- Line 604: Update the `pm test` none-mode example to invoke the test runner
directly instead of through `scripts/run-tests.mjs`, so the SDK test inherits an
unset `PM_PATH` when creating independent tracker roots.
In @src/sdk/merge/install.ts:
- Around line 656-674: Update the fence validation flow around `owned` so zero
matching blocks returns a `not_installed` result with the fence path and
expected patterns. Update `validate.ts` and its diagnostic contract so this
path-bearing status still emits the validation warning; preserve the existing
handling of other statuses.

Document that scripts/run-tests.mjs creates its own PM_PATH after the linked none-mode runner removes the inherited value. Use a direct Vitest command in the snapshot example and record temporary-clone verification plus merge-fence review disposition in the linked PM items.
