mathiasandClaude Opus 5.5 ddd4bdc2ac fix(brainfs): refuse a file behind a symlinked directory for reads and writes (#173) (#187)
CI / Lint / Test / Vet (push) Successful in 1m2s
CI / Mirror to GitHub (push) Successful in 3s
ReadRegular, ReadRegularMax and WriteRegular require a clean, local path and a real directory at every level above the file, so an in-brain directory symlink (or a ".." after one) can no longer redirect brain_update, brain_tunnel, brain_read/get or the other readers elsewhere in the brain. session.Append opens through an os.Root on the brain dir, refuses a non-directory sessions dir, and writes only after confirming the log path is the regular file it opened.

Fixes #173. Adversarial review: BLOCKED, PASS. Follow-up: #188 (brain_write create path).

mathiasandClaude Opus 5.5 febab3e45d fix: brain_tunnel, brain_update and session_log confine caller-supplied paths (#169) (#170)

brain_tunnel accepts only clean wiki/.../*.md paths and reads/rewrites both notes through brainfs; new brainfs.WriteRegular never creates, never writes through a final symlink (Lstat + O_NOFOLLOW|O_NONBLOCK + os.SameFile on the handle, since os.Root follows in-root final symlinks even with O_NOFOLLOW). brain_update resolves like brain_edit (knowledge/ and wiki/ notes only) and reads/rewrites through brainfs. session_log requires a plain-name session id and opens with O_NOFOLLOW|O_NONBLOCK.

Fixes #169. Adversarial review: BLOCKED, BLOCKED, PASS (round 3 by the estate session's reviewer). Follow-ups: #173, #174.
