From 848a4583da8de87f52c80b30dd9af945b1783e4b Mon Sep 17 00:00:00 2001 From: root Date: Sun, 3 May 2026 05:23:54 -0500 Subject: [PATCH] phase 1.6 Gate 5: erasure endpoint POST /biometric/subject/{id}/erase MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per docs/runbooks/BIPA_DESTRUCTION_RUNBOOK.md. BIPA-defensible erasure: clears biometric collection (and optionally full PII record), unlinks the photo file, records the destruction in the per-subject HMAC chain. The audit row is the legal proof of compliant destruction even after the underlying data is gone. Two scopes: biometric_only (default): clears biometric_collection field, unlinks the photo, sets consent.biometric.status = withdrawn. Subject remains active. full: above PLUS sets status = erased and consent.general_pii.status = withdrawn. Manifest preserved (proof of destruction); subject record is logically erased. Triggers (recorded but not validated against a closed set): retention_expiry | consent_withdrawal | rtbf | court_order Body shape: { "trigger": "", "trigger_evidence_path": "", "operator_of_record": "", "witness": "", "scope": "biometric_only|full" } Response (biometric_erase_response.v1): candidate_id, scope, trigger, erased_at, fields_cleared, photo_unlinked, photo_unlink_error, status_after, biometric_status_after, general_pii_status_after, audit_row_hmac Order matters for BIPA defensibility: 1. Snapshot original manifest (rollback target) 2. Update manifest (logical erasure) 3. Append audit row (LEGAL proof of intent + scope + operator) 4. Best-effort secure overwrite + unlink photo file (irreversible last) If audit append fails, manifest is rolled back to original state and 500 returned — the alternative (manifest erased without legal record) is exactly the silent-failure mode the spec exists to prevent. If photo unlink fails AFTER audit commits, the response carries photo_unlinked=false + the error string; operator must manually shred. Tracing logs the inconsistency loudly. Tests: 21 unit tests now pass (10 erasure-specific): - missing token / missing subject / 404 - missing trigger / missing operator / invalid scope (400) - biometric_only happy path (file unlinked, fields cleared, audit kind=biometric_erasure) - full scope (status=Erased, general_pii withdrawn, audit kind=full_erasure) - idempotent on already-erased (audit row records "already_erased" result) - no-photo case (photo_unlinked=true with no unlink error) - chain links off prior audit row's row_hmac (NOT GENESIS) Live verification (post-restart): - POST /biometric/subject/WORKER-2/erase with consent_withdrawal trigger → 200 with all expected fields_cleared + photo_unlinked=true - Manifest reflects: biometric_collection=null, consent.biometric.status=withdrawn - GET /audit/subject/WORKER-2: chain_verified=true, 4 rows total, latest kind=biometric_erasure with operator + trigger in purpose field - Cross-runtime parity probe: 6/6 byte-identical post-change Known follow-up (separate bug): photo upload endpoint overwrites biometric_collection without handling a prior file's data_path — multiple uploads for the same candidate orphan earlier files. The erasure endpoint correctly unlinks what the manifest knows about; operator must shred orphans manually until the upload endpoint either rejects re-upload (preferred) or maintains a list.
