Key Features

• Gate 2 refuses a silent gap: an acceptance criterion with no test and no open tracked-debt task fails the build rather than passing quietly
• Emits trace-manifest.json (v4) and trace-manifest.v5beta.json, one row per registry ID with its status and the evidence behind it
• Five statuses, including retired for an intent withdrawn on purpose, so a withdrawal is never mistaken for a gap
• Mints durable IDs at intent and refuses an ID the project's own configured grammar would reject
• Coverage matrix and portfolio snapshot for CI and for cold readers

Testing Checklist

• Extension installs successfully via download URL
• All commands execute without errors
• Documentation is complete and accurate
• No security vulnerabilities identified
• Tested on at least one real project

Submission Requirements

• Valid extension.yml manifest included
• README.md with installation and usage instructions
• LICENSE file included
• GitHub release created with version tag
• All command files exist and are properly formatted
• Extension ID follows naming conventions (lowercase-with-hyphens)

Testing Details

This updates the existing catalog entry from 0.4.12 to 0.5.1. It supersedes
issue #4252, filed at 0.4.12 and merged as catalog PR #4254, and replaces
#4649. Neither v0.4.13 nor v0.5.0 was ever filed, so this one carries three
releases of change.

Tested on: Linux, Spec Kit 1.0.5, Python 3.11.15, on 2026-09-20.
Previously captured on Spec Kit 1.0.4 at release time, 2026-09-17.
The >=0.14.0 floor was exercised at v0.5.1 on 2026-09-17: the bundle installs
and the Gate runs on 0.14.0, though that version does not scaffold the settings
file, so the Gate reports config: MISSING and continues on defaults.

Test scenarios, in a clean project (specify init . --here --force --non-interactive --integration claude):

1. Installed direct from the download URL:
   $ specify extension add specassay-check --from
   installed; specify extension list reports SpecAssay Check (v0.5.1)
2. Ran the Gate on an empty project. It refuses and names the fix:
   FAIL: registry not found: PRD.md
3. Ran the Gate on an empty-but-present registry. Exit 0, and it prints the
   on-ramp naming both mint routes.
4. Minted a first ID:
   $ bash .../mint-id.sh AC LOGIN --append "Given a wrong password, ..."
   AC-LOGIN-10
5. Ran the Gate again. It refuses honestly, which is the intended first red:
   FAIL: registry ID missing from specs: AC-LOGIN-10
   FAIL: registry ID missing from tasks: AC-LOGIN-10
   FAIL: silent gap: AC-LOGIN-10 has no test and no open tracked-debt task
   exit 1
6. Added a spec line and one open task carrying the ID, the documented way to
   clear it:
   SpecAssay Check (Gate 2): OK (1 registry IDs)
   exit 0, and trace-manifest.json reports AC-LOGIN-10 as tracked-debt.

The extension is also run against its own repository on every pull request,
where it currently reports OK on 71 registry IDs.

Example Usage

# Install from the release archive
specify extension add specassay-check --from https://github.com/rdryfoos/specassay/releases/download/v0.5.1/specassay-check-0.5.1.zip

# Mint a durable ID at intent
/speckit.specassay-check.mint AC LOGIN "Given a wrong password, when the user signs in, then the form shows an error and no session starts."

# Run Gate 2; a silent gap fails the build
/speckit.specassay-check.gate

Additional Context

Update to an existing entry, not a new extension. Replaces #4649.

provides.commands moves from 2 to 5. It has been stale since v0.4.13: dig,
matrix and portfolio shipped after the 0.4.12 entry was written. The five
are speckit.specassay-check.gate, .mint, .dig, .matrix and .portfolio.

Companion issues in this submission: the preset (updates #4253) and the bundle
(updates #4255). The bundle pins both component versions, so all three need to
land together or specify bundle install cannot resolve.
