Supersedes the abandoned PR #8 (`mitmproxy-tls-interception`),
which built a mitmproxy + addon chain on the (falsified) premise
that pipelock could not MITM. Empirical proof from the impl-time
spike: with `tls_interception: { enabled: true, ca_cert, ca_key }`
in pipelock's config, pipelock answered a credential POST over
HTTPS with `STATUS=403 / body: blocked: request body contains
secret: GitHub Token` and emitted both `scanner:"tls_intercept"`
and `scanner:"body_dlp"` events. Standalone, no second proxy.
Net change vs PR #8: one sidecar instead of two, no vendored
addon, no addon-verdict pattern matching, no HTTPS-trust /
DNS / lookup workarounds. Same end-state behavior — pipelock's
DLP fires on plaintext for HTTPS hosts in the allowlist.
Also cleaning up the now-stale TLS-research notes:
- `docs/research/tls-mitm-for-pipelock.md` is removed. Its
entire premise (mitmproxy in front of pipelock) is moot now
that pipelock does the work natively. The mechanics of CONNECT
bumping and the CA-lifecycle considerations it documented are
the same as what pipelock implements; the PRD restates the
parts that matter for the integration.
- `docs/research/pipelock-assessment.md` had two stale claims
corrected: the "Pipelock does not perform TLS inspection (no
CA trust injection)" line in §Scope gaps and the
"no TLS termination" cell in the comparison table. Both now
point at the `tls_interception` config and `pipelock tls`
CLI instead.
