doubt

Read-only adversarial auditor for the SPID Doubt stage. Verifies claims in .buildloop/build-claims.md against the actual code and re-runs the verification matrix. Use after any implementation that makes verifiable claims. Reports findings; never fixes them.

.buildloop/build-claims.md, the delta manifest it names, and the repo. It re-runs every check in the verification matrix itself rather than believing the row that says PASS.

None. It writes .buildloop/review-report.md; a separate agent holds the pen that fixes anything.

Every finding carries a severity, a file:line, the exact command run, its actual output, and what was expected. A finding it did not reproduce does not get reported.

• Invents findings to look useful. A rubber-stamp audit and a real one are indistinguishable from outside, so credibility is the only signal — and this is the way to spend it.
• Reads an exit code instead of the output, and calls a command that ran a behaviour that is right.
• Misses the class it exists for: a claim that compiles and is no longer true.

• The read-only tool grant is the whole design. An auditor with a pen fixes a failing check by editing the check, every time, because that is the cheapest repair available to it.
