A clip dropped in raw/ with no other action lands in web-clip, its entity and
concept are the shared pages, raw/ is empty and nothing waits for a human;
client-marked text and a typo'd wing name park; a deliberate subfolder places.
Real pipeline and file layout, model stubbed.

With Config.Wing a source goes to wiki/<wing>/sources/ (wing/hall frontmatter);
concepts and entities stay in the shared wiki/concepts and wiki/entities, so an
entity cited from two wings is ONE page with both sources (the per-wing facts/
layout duplicated it). A source slug already used anywhere but its own wing's
sources/ is refused (slug is the graph identity). wiki.FindSlug added.
Mutation-checked: collision guard, shared inventory, per-wing source path.

No model. A subfolder/frontmatter wing must be a plain name of an existing wing
and then places; conflicting signals and client-marker text park; everything
else goes to the default wing. Wings are read from disk per decision.
Mutation-checked.

MaxNoteBytes (default 64 MiB) is checked on the Lstat size before extraction;
an oversize note stays in raw/, is reported once and not retried until it
changes. The #199 case (marker name over NAME_MAX) is covered by the
remember-on-any-failure retire path and now has a test that fails without it.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Reconciled with v0.25.0 semantics:
- markers are only the fallback when the original cannot be removed, and are
now written through the brain root; the refused set (size+mtime keyed) replaces
the path-only 'stuck' set
- #195's tests updated for inbox zero (archive written, original retired, no
marker), and the planted-marker-link test keeps its point: nothing is ever
written through the link, and the note is processed once
- the 'cannot retire' test now counts archive copies; it counted LLM calls,
which pipeline.Run's source-hash check hides (mutation: removing the
remember step left it green)
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
From the second independent review of #207:
- parkForReview now skips the delete when the note changed since it was read
(an LLM call sits in that window; Syncthing can deliver a newer version)
- parked copies are created via brainfs (real dirs only, O_EXCL, no symlink
following), so a planted raw/needs-review symlink cannot redirect or hide a
note; this also removes the need for the guard allowlist entry added in
1e14c56, which is reverted
- a '----' line no longer closes the proposal block
Each has a test that failed first and a mutant that fails it.

The previous commit was pushed with this guard red: the gate was run with ';'
instead of '&&'. Allowlisting is the guard's own sanctioned mechanism and is
called out for review.

From the independent review of #207:
- parked notes are created O_EXCL with -2,-3 suffixes (same-named notes from
different subfolders were overwritten and their originals deleted)
- proposed_wing is emitted only if a plain wing name; a note's own proposal_*
keys are dropped so they cannot outrank the resolver's (first-wins reads)
- CRLF notes: wing: key honoured, one valid frontmatter block on parking
- KnownWings skips wiki dirs that are not canonical lower-case names
- adds the wingmigrate dry-run/apply command
Each fix has a test that failed first and a mutant that fails it.

Sources are placed by the wing Resolver; concepts/entities inherit the strict
majority wing of the sources that cite them. Collisions, junk (auto-tunnel
logs) and anything unplaceable are Exceptions left in place. Apply writes the
destination O_EXCL then removes the source, only for Auto items.
Mutation-checked (junk guard, majority, slug identity, status gate,
no-overwrite, destination-exists).

The first version fed the text through a path that never carried it into the
file, so it passed under the mutant. A classifier error does carry it; the
test now fails with %q replaced by %s.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Approval is moving the note into raw/<wing>/ (the watcher ingests it there);
a dedicated approve tool is tracked separately. Proposal reason is written
Go-quoted so LLM text cannot start a frontmatter key; pinned by a
mutation-checked test.

Off by default (retired layout unchanged). On: eligibility from
classification.yaml, local ingest LLM as classifier, BM25 as cross-check,
INGEST_WING_THRESHOLD (default 0.9, rejected outside [0,1]). Build failure
is fatal when explicitly enabled.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
With Config.Resolver set, an explicit subfolder/frontmatter wing or an agreeing
classifier+scorer routes the note into that wing; anything else is parked with
its proposal in frontmatter and never extracted. needs-review/ is skipped by
the walk like rejected/. Nil Resolver keeps the retired layout.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Sources -> wiki/<wing>/sources, concepts/entities -> wiki/<wing>/facts with
kind: frontmatter; inventory, title resolution and back-references are
confined to the target wing. Empty Wing keeps the retired layout unchanged.
Mutation-checked: widening the inventory beyond the wing fails the
cross-wing back-reference test; a non-plain wing name is rejected.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A first backtest showed BM25 summed over a wing's top hits favours big wings
(0/4 agreement). Best-page scoring is volume-robust; pinned by a test that
failed before the change.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Explicit subfolder/frontmatter wins; otherwise a classifier and an
independent scorer must agree above a threshold on a known, eligible wing.
Anything else is an Exception for a human. Never creates a wing, never
assigns an ineligible (client/untagged) wing. Mutation-checked: dropping the
eligibility, known-wing, scorer, threshold or conflict check fails a test.

The archive holds the content read at the start; if Syncthing replaced the
note during the (minutes-long) LLM pass, removing the original would drop the
newer content. Compare size+mtime before removing; leave it for the next poll.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
When both Remove and the marker write fail (read-only raw/), remember the
path in memory so later polls skip it instead of writing another archive
copy every tick. Adds a test that a failed archive copy leaves the original
in raw/, mutation-checked against removing the early return.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
After a note is archived into raw/processed/ or raw/failed/, remove the
original from raw/ so raw/ only holds unprocessed input. The .processed /
.failed marker is now only a fallback when the removal itself fails.
Existing markers are still honoured.

Review round 2 on PR #195: the marker writes had no test, so reverting
them to by-path writes, or the refusal to log-only, stayed green. The
link is planted from inside the fake model call, between the walk's
Lstat and the marker write, for both markers and both an outside and
an in-brain relative target; red on all four flips. The marker-entry
skip is now checked for .failed too.
Also pins cleanRel's acceptance of a backslash as a filename byte in
brainfs itself, and stops the buildAndWrite control claiming writes it
does not count.

An authenticated REST request to an unregistered path reached the inner
mux, which left Pattern empty, and metrics.Middleware fell back to the
raw URL path: any token holder could create one Prometheus series per
unique path. The fallback is now the fixed label "unmatched"; real routes
keep their pattern. Tests: buildMux with an authenticated random path,
and the middleware unit test; the timing test now routes through a
ServeMux as production does.
Fixes#185.

Review round 1 on PR #195:
- A refused marker or archive write left no marker, so the note was
reprocessed every interval (archive copies piling up; an LLM call per
round on the failure path). The marker check now uses Lstat (any entry
at the marker path counts, so a dangling marker link skips the note
instead of looping), and a note whose archive copy or marker write is
refused is remembered (path, size, mtime) and not retried until it
changes.
- cleanRel no longer refuses a backslash: it is a legal filename byte on
Linux, not a traversal, and a raw note named with one was never
archived or marked.
- Tests now reach every converted writer: the log.md append (real
raw/failed so the log is reached, symlinked log.md), a dangling marker
link, the refused-retry loop with a positive control, a backslash name,
a buildAndWrite swap race, and the claude-session archive with in-brain
and outside symlinked archive dirs. The stale lint allowlist entry for
appendWatcherLog is removed.

Three Watch tests flaked under -race and CPU load (3/8 of 8 parallel
x10 runs on main):
- QueueIsBounded slept 100ms before looking for the summary; it now
waits for the summary, then checks the bound.
- DeliversEveryQueuedAlert asserted FIFO order, but the outage ends
asynchronously, possibly mid-flush, so a later item can send first. It
now asserts each removal is delivered exactly once (order is not what
it is named for).
- AccountsForEveryRemoval slept 50ms after the first summary, counted
only "removed 1" and took the last summary's count. It now sums every
"removed N" and every suppression count and waits until they account
for all plants.
Stress: 0/8 failures in three rounds of 8 parallel x -test.count=10 under
-race. Flips still red: unbounded queue, dropped retries, suppressions
not counted.
Fixes#193.

Every alert was titled "brain-capture audit degraded", including the
symlink tripwire's and governance-edit alerts. NtfyNotifier.WithTitle
returns a titled copy (nil stays nil); buildNotifier(getenv, title) is
called per source: capture audit (unchanged title), "brain symlink
tripwire", "brain governance edit". Tests assert the Title header.
Fixes#163.

The remaining writers created or rewrote brain files by path:
- pipeline buildAndWrite: os.MkdirAll + os.WriteFile of every page.
- BackfillRefs: os.WriteFile of each concept page; a page swapped for a
symlink after the read was written through (the race test overwrote an
in-brain target before this change).
- watcher: the raw/processed and raw/failed archive copies (os.Create),
the .processed/.failed markers and the log.md entry (os.OpenFile).
- cmd/server: the claude-session archive.
All now go through brainfs PutRegular/AppendRegular (new package-level
PutFile/AppendFile for one-off writers: the watcher's call-site lint bans
.Open calls in that file so raw/ reads stay on OpenRegular).
Stacked on #189 (needs PutRegular/AppendRegular).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

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.

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.

AssertNoLeakFrom and the search Query race test passed vacuously when
every symlink swap failed or every read errored. Both now count
successful symlink swaps and reads that returned the inside note and
fail if either is zero; the Query race reader no longer swallows
Query's error.
Verified by flipping: a swapper whose os.Symlink always fails turns
notes, wiki and search race tests red; Query on a missing brain dir
turns the search race test red.

The retry landed in 9a232ad but was tested only through startupretry with
fake funcs; nothing exercised chassisauth.NewJWTValidator's real 502 path.
Extracts the main() closure into buildJWTValidator (behaviour unchanged)
and tests it against an httptest issuer: 3x502 then 200 succeeds with 4
discoveries; a persistent 502 stops at exactly the 8-attempt budget with
the last error; cancelling ctx mid-backoff returns context.Canceled.
Flip-verified: Attempts=1 turns all three red.

already shipped in 9a232ad; this is a test plus a pure extraction.
