Risk: low. Two lines of guidance text. No code changes.

What was wrong

The specs instruction named openspec/specs/<capability>/spec.md — a path relative to the current directory — for the two operations that read a capability's main spec. When the change lives in a store, the main spec is under the store root, so that path doesn't point at it.

Two outcomes, and the second is the dangerous one:

  1. The path doesn't exist, so the agent may write a MODIFIED delta from memory.
  2. A local capability happens to share the name, so the read succeeds against a different capability and the wrong requirement gets copied into the delta. Nothing errors.

What changes

Both operations now use <planningHome.root>/openspec/specs/..., with a sentence saying where that value comes from.

Why it's safe

This isn't a new convention — it's the one the workflow templates already use (sync-specs.ts:44). The schema instruction was simply the site that was missed.

Proof

Verified against a real registered store: openspec instructions specs --store mystore --json returns the store root in the same response that carried the wrong path. Mutation-tested regression guards; composed path checked in every root configuration. CI green on all three platforms.

Closes #1702

The spec-driven `specs` instruction named
`openspec/specs/<capability-path>/spec.md` — a cwd-relative path — for the
two operations that touch a capability's main spec: step 1 of the MODIFIED
workflow ("locate the existing requirement") and the edit that fixes a
leftover TBD Purpose.

When the change lives in a registered store, the main spec is under the
store root. Verified against one: `openspec instructions specs --store
mystore --json` returns `planningHome.root` pointing at the store while the
instruction sent the read to the working repo, where the capability does
not exist. Where a local capability happens to share the name it is worse
than a miss — the read succeeds against a different capability and step 2
copies the wrong requirement block into the delta, silently.

Both now use `<planningHome.root>/openspec/specs/...`, the root the same
JSON already returns, matching what sync-specs.ts and archive-change.ts
have said since they were written: use the store-aware root, not a
hardcoded repo path.

Guidance text only — no CLI, parser, or archive behavior changes. The two
remaining `openspec/specs/` mentions describe the shape of a capability
path rather than a file operation, and are left alone.

Closes #1702

📝 Walkthrough

Walkthrough

The specs instruction now uses the store-aware <planningHome.root>/openspec/specs/... path for main-spec reads and edits. The schema documents store resolution, and tests verify the resolved path.

Layer / File(s) Summary
Update main-spec path guidance
schemas/spec-driven/schema.yaml, test/core/templates/main-spec-paths.test.ts, .changeset/store-aware-main-spec-paths.md
The workflow uses <planningHome.root> for main-spec operations. The schema documents store sources and fallback behavior. Tests verify the composed path and instruction text. The changeset records a patch release.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 9f47c

This localized documentation correction makes main-spec reads use the store-aware root and is covered by targeted regression tests; no actionable merge-blocking risk remains after normal checks and review.

…solves

Two hardening findings.

The wording said the root "points at the store when a store is selected."
Verified across all four root configurations, that undersells it: a project
`store:` pointer (source `declared`) and a global default store (source
`global_default`) both resolve to the store with no `--store` flag passed.
An agent reading the old sentence could conclude the case did not apply to
it and fall back to a repo-relative path. It now says to always use the
field and not to reason about which case applies.

The test only pinned the placeholder text, which would still pass if
`planningHome.root` were renamed or the suffix were wrong. Added a guard
that substitutes the placeholder with a real resolved planning home and
asserts the composed path lands on an actual main spec. Mutation-tested:
inserting a path segment and renaming the field each fail it.

Verified end to end that the composed path exists under all three
store-selecting configurations, and under a plain local repo.

Comment thread test/core/templates/main-spec-paths.test.ts Outdated
The guard substituted `planningHome.root` into a template spelled with
forward slashes. On Windows that yields a mixed-separator path, so the
assertion passed because Node accepts forward slashes there rather than
because the path was built correctly. Windows CI was green either way;
this makes the construction right instead of merely tolerated.

The suffix is now captured on its own and joined to the root with
path.join, so the assertion uses native separators everywhere. All three
mutations (cwd-relative path, extra segment, renamed field) still fail
the guard.

Addresses CodeRabbit review on #1703.

Fixed in 9f47c02 — the finding was valid.

The guard substituted planningHome.root into a template spelled with forward slashes, so on Windows it produced a mixed-separator path. Worth being precise about the severity: Windows CI was green before this change too — the assertion passed because Node accepts forward slashes on Windows, not because the path was built correctly. So this was a test passing for the right answer via the wrong construction, not a live break.

The suffix is now captured on its own and joined with path.join(planningHome.root, ...suffix.split('/')), so the filesystem assertion uses native separators on every platform.

Re-ran all three mutations against the rewritten guard to confirm it still bites — cwd-relative path, extra path segment, and renamed field each fail it; restored, 3 pass. Full suite unchanged at 3970 passed with the two pre-existing environment-specific failures.
