mathiasandClaude Opus 5.5 f4636c7ef0 fix: creating and generated writes go through the brain root (#188, #158 part A) (#189)
CI / Lint / Test / Vet (push) Failing after 1m2s
CI / Mirror to GitHub (push) Skipped
New brainfs PutRegular (create or replace), CreateRegular (create only), AppendRegular, Remove and RealParent: missing parents created one component at a time through the root, every existing component a real directory, new files created with O_EXCL and confirmed before writing. brain_write, promote/reject (O_EXCL create, source kept on refusal), StampProvenanceFile, BuildWingIndex, RebuildIndex, AppendLog and the tunnel candidate log use them; provenance.ApplyFile removed.

Fixes #188. Refs #158. Adversarial review: BLOCKED, BLOCKED, PASS.

mathiasandClaude Opus 5.5 77e32de33c fix(graph,wiki): read the brain through brainfs (#157, slice 4) (#168)

graphsync, wiki inventory/index read through brainfs; brainfs refuses an in-brain file swapped in behind a symlink (os.SameFile). Gatekeeper round 2 PASS on d90ce66, CI run 9180 green.

mathiasandClaude Opus 5 125c99bb46 fix(text): truncate on rune boundaries, not byte offsets (#93)
CI / Mirror to GitHub (push) Successful in 4s
CI / Lint / Test / Vet (push) Successful in 31s
Four call sites did `s[:limit] + "…"`. Both halves are byte operations:
len() counts bytes and a slice cuts bytes. On Swedish text — å ä ö are
two bytes, an em dash three — the cut lands mid-character and leaves an
orphaned lead byte, producing invalid UTF-8.

It failed loudly in exactly one place: wiki/index.md is written raw to
disk, where every strict decoder then rejects the whole file. The other
three (brain_context excerpts x2, brain_query excerpts) feed MCP
responses, where encoding/json silently substitutes U+FFFD — so those had
been quietly eating the last character of truncated excerpts, with no
error anywhere and nothing to notice.

textutil.Truncate counts runes and appends the marker only when content
was actually dropped; an ellipsis on complete text is a lie about the
content. The test is a property, not an example: it walks the limit
across every offset of a multi-byte string and asserts utf8.Valid at each
one, so a future off-by-one cannot pass by picking a lucky boundary.
