didericis 545ff3582f fix(lint): resolve pylint and pyright issues on egress-log-option
lint / lint (push) Failing after 1m34s
test / unit (pull_request) Successful in 32s
test / integration (pull_request) Successful in 44s
- egress.py: extract _render_match_entry helper to reduce nesting depth
- egress_addon_core.py: make request_method/request_headers keyword-only
  to satisfy too-many-positional-arguments; wrap long lazy import lines
- egress_addon.py: remove unused Route import; add pylint disable for
  import-error on sidecar-only mitmproxy/egress_addon_core imports
- dlp_detectors.py: remove dead _min_distance function (superseded by
  _closest_pair)

didericis 86b0a4d285 feat(egress): add location, context snippets, and token redaction to DLP logging
Each DLP block/warn now reports where the match was found (body,
authorization header, response body) and includes a context snippet:
SNIPPET_CONTEXT chars before and after the match, with the matched
value replaced by REDACT ("********").

scan_token_patterns/scan_known_secrets/scan_naive_injection all gain
`location` and `context` fields on their ScanResult returns. The
outbound scanner takes `auth_header` as a separate kwarg so the two
locations are scanned and reported independently.

redact_tokens() is added to dlp_detectors and used in egress_addon.py
to scrub token patterns and provisioned secrets from host/path fields
before they appear in any log output (level 1 and 2).

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
