#1636 extension quality awards repository-verified 2/2 for a nonexistent or private GitHub repo

swamp extension quality checks that repository: points at an allowlisted host, but does not check that the repository actually exists or is publicly reachable. Any well-formed https://github.com/<owner>/<name> URL earns the full 2 points, so the local score can exceed what the server will award at publish.

Reproduce

Point repository: at a GitHub URL that cannot exist and score the manifest:

repository: https://github.com/aaron-dernley/this-repo-does-not-exist-9f3a2c

$ swamp extension quality manifest.yaml --json
total: 14/14 = 100%
repository-verified: 2/2 [earned] — Verified public repository (server confirms on publish)

Observed matrix

Same manifest, only repository: varied:

So host allowlisting is enforced; existence and visibility are not.

How it was hit

Real sequence, not synthetic. The extension was prepared with the repo still private. extension quality reported 14/14 = 100%, which reads as "ready to publish at the third-party ceiling". The rubric states the factor is "confirmed via that host's public API", and the score would in fact have been 12/14 at publish because GitHub's public API cannot resolve a private repo. The gap was only caught by having read the rubric — the command itself gives no signal.

Note in mitigation

The factor label does say "(server confirms on publish)", so the behaviour is disclosed. The problem is that the disclosure sits inside one factor object while the headline earnedPoints / percentage — the numbers people actually read, and the ones a pre-publish check is consulted for — silently include the unverified points.

Suggested fix

Any one of:

1. Do the reachability check locally (an unauthenticated GET of the API URL is enough to distinguish missing/private from public).
2. Exclude server-confirmed factors from the local total and report it as e.g. 12/14 (+2 pending server verification).
3. Mark the factor status: "provisional" rather than "earned" so a caller can tell the difference programmatically.
