DC-095: mask email addresses at every logger output choke point so raw
PII never reaches stdout/stderr, error.log, or audit-log.json regardless
of what a call site interpolates — msg strings, data payloads, error
messages/stacks, audit details, and error.log request lines (path/UA).
- Masked shape sa****@domain matches AuthProvider.maskEmail (UI-consistent)
- Bounded-quantifier regex: local {1,64} (incl. quoted local-parts),
domain {0,253}, TLD {2,24} — adversarial 40KB string 3.3s -> 17ms,
hostnames/versions/docker-refs untouched, idempotent under re-mask
- memo-Map recursion: DAG shared references get the same masked clone
(WeakSet seen-guard leaked the raw original on 2nd reference); cycles
resolve to in-progress clone
- Non-plain objects with own enumerable props cloned proto-preserving
(Object.create) so class-instance email fields are masked; Date/RegExp
pass through
- sanitize(): audit details mask email substrings in non-sensitive keys
(invite/auth POST bodies no longer land raw in audit-log.json)
- 18-test suite covers sinks + adversarial judge findings (ReDoS timing,
DAG, quoted locals, instances, request-line path/UA)
Judge: GLM-5.3 cold-read stand-in (Codex quota-dead until 2026-08-24,
substitution authorized by Sami 2026-08-17). Rounds C -> C -> A.
Verdict: urn:ump:zorj7vcrnw2t2jhhcp2g6wz4simvhyjdqwu2mjsifxlkzb2dwjmq
Suite: 117 suites / 2724 tests green.
