didericis-claude abcb336e7c fix(dlp): rework naive injection to proximity-based disclosure+jailbreak
lint / lint (push) Failing after 1m24s
test / unit (pull_request) Successful in 30s
test / integration (pull_request) Successful in 44s
Token detection is already handled by the token_patterns detector
running separately — calling it again from scan_naive_injection was
redundant. New logic:

- Warn on any disclosure phrase
- Warn on any jailbreak phrase
- Block when both appear within 500 chars of each other

didericis-claude 726713d081 feat(egress): implement PRD 0053 — DLP addon with Gateway API matches
lint / lint (push) Failing after 1m43s
test / unit (pull_request) Successful in 40s
test / integration (pull_request) Successful in 50s
Replace path_allowlist with Gateway API HTTPRoute match vocabulary
(paths, methods, headers with AND/OR semantics) and add DLP scanning
to the egress proxy:

- Token pattern detection (AWS, GitHub, Anthropic, OpenAI, Stripe, JWT)
- Known secret detection (EGRESS_TOKEN_* with base64/URL/hex variants)
- Naive prompt injection detection (disclosure + credential, jailbreak)
- Per-route DLP configuration via manifest dlp block
- Inbound response scanning with block/warn severity

didericis-claude 5265e25f9b docs: address PR #196 review; update research decisions and PRD
test / unit (pull_request) Successful in 30s
test / integration (pull_request) Successful in 41s
Research doc: close open questions with decisions from review — hard
cutover on path_allowlist, drop glob (regex sufficient), stick with
Gateway API OR semantics for headers, case-insensitive method names.

PRD 0053: adopt Gateway API HTTPRoute match vocabulary (paths, methods,
headers) as the route schema replacement for path_allowlist. Add
MatchEntry / PathMatch / HeaderMatch types to EgressRoute design; cite
the route matching research doc; fold match restructure into chunk 1
alongside the dlp block.

didericis-claude f145203eee docs: PRD 0053 — egress DLP addon (token, secret, injection detection)
test / unit (pull_request) Successful in 30s
test / integration (pull_request) Successful in 46s
Adds the product requirements document for replacing pipelock's DLP
capability with a per-route mitmproxy addon. Covers three implementation
chunks: token-pattern detection, known-secret detection, and naive prompt
injection scanning. References the research in PR #192 and issue #195.
