Give each egress route a policy for what the proxy does when an outbound
DLP detector matches a token, defaulting to the supervise flow added in
the previous commit. The goal is cutting false-positive friction without
weakening default-deny.
- redact: scrub the matched value(s) from the body, non-host headers, and
path/query via redact_tokens, then re-scan. Forward if clean; fail
closed with a 403 if a match remains on a surface redaction can't
rewrite (the hostname, or a unicode-evasion token). For routes where a
token-shaped value is noise the upstream doesn't need.
- block: the original hard 403, never overridable.
- supervise (default, unset): hold the request for operator approval.
Structural blocks (CRLF, no safelist-able value) stay hard 403s under
every policy.
Threads outbound_on_match from the bottle manifest (manifest_egress)
through the resolved EgressRoute and rendered routes.yaml (egress.py) to
the addon's Route (egress_addon_core), and round-trips it via the
list-egress-routes introspection endpoint. The allow/egress-block tool
descriptions document the new key.
Tests: manifest parse/validation, core parse/validation, full
manifest->render->addon round-trip for redact. README + PRD 0062 updated.

When the outbound DLP catches a token, route the block through the
existing supervisor approval queue instead of returning 403 outright.
The egress proxy holds the request open until the operator answers, then
remembers an approved value for the life of the proxy so the request --
and later ones carrying it -- flow through. Fails closed on rejection,
timeout, malformed response, or when supervise is disabled.
- ScanResult.matched carries the raw matched substring (sidecar-only;
never logged or written to the proposal). scan_outbound and the token
detectors take a safe_tokens set and skip approved values, continuing
past a safelisted match so a second secret in the same request is
still caught.
- New egress-token-allow proposal tool, written directly to the queue by
the addon (the gitleaks-allow pattern from PRD 0061). build_token_allow
_payload renders host/method/path/detector reason + redacted context.
- Async request hook polls the queue without stalling the proxy event
loop; EGRESS_TOKEN_ALLOW_TIMEOUT_SECONDS (default 300) bounds the wait.
- Supervisor TUI renders egress-token-allow like gitleaks-allow: report
only, modify unavailable, approval requires a recorded reason.
- Unit tests for the matched/safe-tokens plumbing, payload builder, tool
constant round-trip, and TUI paths; README + PRD 0062.
Closes#261.
