Once a fingerprint canary's HTTP beacon passes all 4 validation layers
and the trigger row lands, the token is immediately set to state=revoked
and canary.<id>.revoked is published on the bus. The slug lookup is
tightened to only return planted tokens, so subsequent requests to the
same URL silently return the transparent GIF without persisting anything
(stealth posture preserved). Plain http/dns canaries with no
fingerprint_nonce are not affected.
Changes:
- sqlmodel_repo/canary.py: add state == "planted" filter to
get_canary_token_by_slug so revoked slugs resolve to None
- worker.py: after record_canary_trigger, if parsed_fp survived all
layers and token has a fingerprint_nonce, call
update_canary_token_state("revoked") + publish CANARY_REVOKED; errors
are best-effort (trigger row already landed)
- test_worker_http.py: assert state=revoked in test_fp_valid_nonce_persists;
new test_fp_deregisters_slug_after_valid_hit (second hit records nothing);
new test_plain_http_canary_not_deregistered (env_file stays planted)
