garrytanandcapy-ai[bot] c2eb035551 fix(qa): an invalid-input probe breaks only the rule it tests
The paid gate's qa-functional-cli-report failed again on #3236 (run
39001107574): the agent probed the digits-only amount rule with -5, which
the positivity check rejected first, so the planted parseInt defect stayed
hidden and it reported no defect. The contract map's invalid-input row now
asks for each input to break only the rule it tests, so another check
cannot reject it first.

Functional QA with repository-native tools

Use documented repository commands, CLI/API clients and job/queue tools, not a new harness or browser substitution.

Functional modes

For /qa and /qa-only, within the selected scope:

  • Full (default): cover every applicable documented contract below.
  • Quick (--quick): check success and the highest-risk changed edge; mark other contracts not run.
  • Regression (--regression <previous-report>): before probes, read the supplied functional report and linked replay evidence. A missing, unreadable or wrong-target baseline blocks regression mode. A browser-only baseline.json is not a functional baseline. Re-establish owned setup; replay prior failed probes against the documented expectation, never recorded buggy output, then check changed adjacent behavior. Preserve the prior report; report fixed, still failing and new findings separately. Missing safe replay inputs block affected probes, never count as passes.

Mixed runs apply each surface's mode separately. /review and /ship retain their caller's bounded smoke and explicit plan checks, not Full exploration.

Contract map

Record each contract/source, isolated setup, exact probe, expectation and outcome: pass/fail/blocked/not run/inconclusive/not applicable (reason).

Contract Observe
Successful execution Expected return/output and final business effect, not just launch/acceptance
Invalid/missing input One probe per documented input rule (allowed characters, format, sign, range, arity), each input breaking only that rule so no other check rejects it first: declared rejection, correct status and no forbidden state change
Authentication/authorization Valid identity, missing/invalid identity, wrong owner/role and durable no-effect boundary
CLI process contract Exact exit code, stdout and stderr separately; resulting file/state changes
State transitions Initial, intermediate and completed/failed states and their permitted transitions
Timeout/cancellation Deadline, partial state, termination of owned work and recovery
Retry Attempts/backoff/terminal state promised by the repository; no unbounded retry
Duplicates/idempotency Repeated request/event and number of durable effects under the documented guarantee
Concurrency/order Controlled competing operations in both relevant completion orders; final invariant
Partial-failure recovery Interrupt after an effect, restart/replay, inspect completion/dead-letter state and duplicates

Do not impose universal exactly-once delivery. Separate acceptance, enqueue, processing, retry/dead-letter and final effect; 2xx is not completion. Expected rejection/injected failure may pass; a missing service preventing execution blocks coverage.

Execute and retain evidence

  1. Apply the shared isolation/permission preflight. Verify cwd, command, environment NAMES and safe reset; use synthetic data/credentials.
  2. Follow the shared exploratory loop's order and written checkpoints. For every probe, inspect initial/final durable state and retain exit/status and stdout/stderr separately without masking failure.
  3. On timeout, retain partial output/state and stop only owned work. Record setup errors and untested contracts; never patch product code to hide missing prerequisites.
  4. Record exact command or method/path/headers/body, setup/reset, expected contract/source, observed output/state, revision/runtime, evidence paths and limits. Secrets are referenced only by environment name. Disclose replay limits caused by redaction.
  5. Use templates/functional-report-template.md relative to the installed QA SKILL.md. Preserve evidence before owned cleanup and disclose leftovers. Return to the caller without expanding discovery authority.
