 - B6 RED: fault injection only wrote `.selftest-*` files. The synthetic path was removed; the P2–P8 matrix enters the normal action flow, proves an action observation occurred, injects after each real phase, and fingerprints rollback.
 - B7 RED: an HTTP-200 empty body exits zero when piped to Bash. The fetched installer must now be non-empty, digest-equal to `tools/install.sh.sha256`, and that exact file is executed; failed/empty/mismatch controls are blocking and CI has a remote immutable-commit arm.
 - B8 RED: raw combined command output was duplicated to terminal and `commands.log`. Both capture layers now redact before output/persistence; a seeded canary is positively emitted by the fake credential-capable registry and must remain absent from terminal, command log, npmrc, generated files and observed argv. The real greenfield fixture also scans those populations.
-- Advisory code review findings are fixed: URL userinfo redaction now handles raw `@`, repeated `:`, percent encoding and multiple URLs in both capture layers; the real greenfield path positively emits its canary through `state_run_captured`; and verified-fetch removes its temporary body after successful execution.
+- Advisory code review findings are fixed: URL userinfo redaction now handles raw `@`, token-only and percent-encoded forms, repeated `:`, multiple URLs, Authorization/Basic, npm `_auth`, and Cookie headers in both capture layers; the real greenfield path positively emits its canary through `state_run_captured`; verified-fetch removes its temporary body after successful execution; and plaintext diagnostics exist only in process-substitution pipes rather than interruptible temporary files.
 - Advisory security review's independent trust-root finding is **DEFERRED by canonical PRD v2 §3**, which explicitly excludes signed provenance. README now states precisely that the same-origin sidecar detects empty/corrupt/inconsistent publication but cannot authenticate against repository/server compromise; no stronger claim remains.
 - The web1 no-manifest representativeness observation is recorded but intentionally not acted on: it is explicitly outside these eight blockers. This remediation does not weaken or otherwise change P9's manifest-presence assertion.
