Two faults, both found while a hang could not be diagnosed from the node's
own journal.
`except Exception` does not catch `CancelledError`, which derives from
BaseException. A cancelled extraction therefore sent no reply and logged
nothing at all, leaving the client waiting on something nothing would ever
answer — the one shape that cannot be reported by whoever hits it. It now
answers, logs, and re-raises so the cancellation still propagates.
And the handler logged nothing on any path, so the journal could not even say
whether a request had arrived. It now names the file, the track, the file size
and the free slot count on entry, the moment the transcode slot is taken, and
the duration and byte count on the way out — the size and duration because the
extraction is a whole-file demux and its cost is set by the file, not by the
subtitle.

The documented setup was `pip install pytest pytest-asyncio aiosqlite`, three
lines under a rule saying not to install packages that are not declared in a
pyproject.toml. All three packages declare a `dev` extra, and the hand-written
list missed what was in it.
It cost three invisible things. Without `piexif`, `test_enrich_photo.py` fails
at import and the whole node suite stops at collection — not one test, the
run. Without `pytest-timeout`, `timeout = 60` in pyproject.toml is an unknown
config option, so the protection its own comment describes ("a hung test must
not wedge the run") was absent, announced only in a warning among the
deprecation notices. Without `ruff`, the project's linter is not installed.
`aiosqlite` never needed naming: it is a runtime dependency of the hub and the
node and arrives with the `-e` installs.
Verified with the corrected line: 2804 tests collected, 2800 passed, 4
skipped, and no unknown-option warning — nothing exceeds the timeout that is
now actually enforced.

The comment claimed a <track> appended after playback started is not shown by
its `default` attribute. Chrome shows it: in a headless run the TextTrack read
back "showing" before the effect had touched it, with its cues already parsed.
The effect stays, for the two reasons that are true — `default` says nothing
about turning subtitles off again, and an explicitly assigned mode means the
same thing in every engine — but the reason written beside it was not one of
them.

MSE decodes no in-band text track, so a subtitle cannot ride inside the
fragmented MP4 the player is fed. The node extracts one track whole, converts
it to WebVTT and caches it under its own hash; the client pulls that blob
through the ordinary file_req/chunk path and hangs a <track> on the video
element — the same indirection as a TMDB poster or an audio transcode, which
is what makes a film's subtitles extracted once in the life of the file rather
than once per viewing. Whole-file also makes the cues absolute, so a seek and
an audio-language change both leave the track untouched.
**The ordinal counts every subtitle stream, including the ones never listed.**
Only text codecs are offered: a bitmap track (PGS, VOBSUB — about a fifth of a
real library) has no path to WebVTT without OCR, and one extracted anyway
yields a header with no cues, which is a menu entry that shows nothing and
reports no error. Numbering the survivors of that filter would give a
PGS/SRT/SRT file the ordinals 0 and 1 for its text tracks and `-map 0:s:0`
would then extract the PGS — the same trap `AudioTrack.ordinal` exists for,
one level deeper. A fixture whose first subtitle stream cannot be decoded pins
it, and the handler checks membership of the probed list, never a range.
Additive and MINOR: the selector is drawn from `subtitle_tracks` in the node's
own `stream_init` and from no version number, so `subtitle_req` is never sent
to a peer that would not answer it. The floor stays at 3.0.
Also here: a failed extraction never touches playback, a superseded reply
cannot install its blob over a newer choice, and `_languageName` is shared
with the audio labels — lifted by both label harnesses, since a lift that
names one function stops covering the rule the moment logic moves out of it.
Tests: 9 node (tracks told apart by the words in the extracted cues, not by
tags), 10 client. Full suite green: 1545 node/common, 1252 hub.

The audio-track selector was drawn with `volume` — the same glyph the music
player uses for its level control, and the same one the browser draws a few
dozen pixels below it, since the video player mounts `<video controls>` and
gets the native volume speaker with it. One drawing, two meanings, in one
window.
`speech-pair` is two offset bubbles: the same line, said twice, which is what
the button chooses. Nothing crosses anything — the set is stroked with no
fill, and two overlapping outlines read as a tangle at 20 px — and it leaves
the conventional subtitle glyph free for the button planned beside it.

names its parameters
`pw_version` 4: Argon2id 64 MiB, t=3, lanes=4 — RFC 9106's second recommended
setting. A v3 hash (256 MB) still verifies at its own parameters and is
rewritten at the new ones on the next sign-in, through the rehash path that
already existed.
Why not more. The verifier matters against an offline attacker holding the
database; online guessing is bounded by the sign-in lockout. That attacker pays
the client's 600 000 PBKDF2-SHA512 iterations and the hub's Argon2id per guess,
since `auth_key` is 256 bits and cannot be searched directly. Memory above
64 MiB multiplies that cost by a constant — at most 16 at 256 MB, less with
PBKDF2 counted — while the hub pays the same memory at every sign-in, one
derivation at a time. Measured on meshbay.org: 450 ms at 256 MB, 105 ms at
64 MiB, so a burst of sign-ins clears about four times faster.
Changing the current version exposed a latent lockout. `hash_password` always
used the current version's parameters, while the raw-password scheme recorded
`pw_version = 2` — harmless while versions 2 and 3 shared their parameters,
and with version 4 every legacy registration and v1→v2 rehash would have
stored a 64 MiB hash labelled 256 MB, which nothing could then verify. Seventeen
tests caught it. `hash_password` now takes the version it is hashing for.
The OpenSSL deadlock between two concurrent `lanes=4` derivations is the same at
64 MiB, so Argon2 stays on its single worker. The loop-stall test measures
against a v3 hash, because half of a 45 ms inline derivation is too close to
scheduling noise to be a reliable bound.

A seek now begins picture and sound together at the keyframe, but stream_init
still reports the position that was asked for. §15.3 says what the fix costs
and why it has not been made.

-ss before -i cannot trim copied video, which must begin on a keyframe, but
accurate_seek did trim the re-encoded audio to the exact request. Every seek
on a copied stream therefore opened with a GOP-wide hole in the audio and ran
a GOP out of sync afterwards — 9.979s on a real film with a 10s keyframe
interval. Accurate seeking is now off wherever video is copied, and stays on
where it is re-encoded, which is the only path that could already begin where
it was asked to.
Every timestamp was correct throughout, which is why nothing caught it; the
tests assert on decoded audio and on frames compared against the source.

`{ ..._auth }` after the await spreads a null _auth to {}, so the renewal
stored a token with no username and no userId. The app renders the
signed-in interface from that and throws on user.username[0] — a blank
page on every load, in localStorage, until the site's data is cleared.
The sign-out wins the race now, and loadAuth treats an identity-less
object as signed out so a browser already holding one heals itself.

The streaming path mapped 0:a:0 unconditionally, so a dubbed film played in
whichever language was muxed first and the others were unreachable. The node
now enumerates the tracks in stream_init and honours audio_track in
stream_req; switching is the seek path, since one ffmpeg carries one track.
MNP 3.2, additive: the player draws its selector from the node's own list and
never from a version number, so an older node is never asked for a track it
would ignore. MNP_MIN_SUPPORTED does not move.

boot-guard.js is a classic script loaded before the module graph, so it
survives the graph failing to link. If #app is still empty after ten
seconds it names what failed and offers a reset of this origin — cache,
storage, databases and the service worker, which clearing the cache does
not touch.
Two real defects found building it: openDB never settled when an upgrade
was blocked by another tab, and a connection it gave up on stayed open
and squatted the database.

The ceiling is 1200 tracks on a library that repeats and 660 on one that
never does; the message said 1000, which would send a reader back into the
wall at 660. It says 500, measured at both ends.

A DataChannel send() throws above the max-message-size the node advertises
(aiortc: 65536), so the 1 MB body cap was unreachable and each body push
swallowed the difference in a bare catch. Cap at 62 KB after sealing, name
the playlist in the sync result, keep syncing the rest.
Measured: 1000 tracks seal to 53 276 bytes, so the ceiling is ~1200.

The six MNP 3.1 ops were the only new ones never crossing a channel in a
test. Two cases on the existing aiortc harness: a round trip read back on
a second connection, and a 256 KB body. Found that the 1 MB body cap is
unreachable from a browser — docs/playlists.md §15.3.

`max-height: calc(100vh - 16px)` says how tall the menu may be and nothing
about where its bottom lands, so one opened partway down the window ran
past it and its last rows scrolled out of reach. Measure from where the

The dismiss-on-scroll listener is on the capture phase, because `scroll`

tracklist closed the moment it was wheeled. Filter on the event's origin.

Reported from a phone: signing in with the same account showed no
playlists. syncWith was called from exactly one place in the interface,
so creating a playlist, deleting one, removing a track and saving the
queue all wrote to IndexedDB and stopped there. The store pushes itself
now, coalesced, so a new mutation cannot forget to.
Silence was the real defect. The node audited only successes, so a
refusal left no trace and user_blob_list none at all; the background
push swallowed its reason; the interface said nothing. All three report
now, and "Sync now" says what happened either way.
An unreadable blob on a node was treated as a fetch failure and returned
before the push — permanent, once the node held anything. It is an
absence: the client is the authority, and it gets overwritten.
A sign-in reconciles whatever this browser already holds, a pending push
is flushed when the page goes away, and a push that did not land is
retried once.
no_key is spelled out: a client that signs in with its remembered device
key only ever has a bundle key persisted before the playlist subkey
existed, and an AES handle is non-extractable.

An artist with one album got a heading and one cover on a row that fits
five, and a library is mostly single-album artists. Consecutive singles
share one grid, in place, so the page stays in artist order.
Each pooled cover keeps its artist's name above it in the same type as
a section heading. Dropping it was the first version and it was wrong:
scrolling then alternates between artists written large and small.
Measured on the probe's fixture: 4208px to 1895px, and a walk of the
page reaches all 21 covers instead of 9.

Fourteen places the proposal was wrong, listed rather than edited away:
the MNP bump was 2.1 and is 3.1; the kind pattern refused the one
playlist every account has; confirm() is the house style and prompt()
is what throws; submenus expand in place; deflate is 4.5x and the
first fixture's 23x was a property of the fixture.
Adds the hazard the proposal missed entirely: two wrappers that take
two arguments and forward two, so every "add to queue" arrived as a
plain play.
The acceptance section now says what is checked and what is not —
no real daemon round trip, no two-browser convergence, no Firefox.

One button in Music's sticky toolbar — load, create, delete, remove a
track, sync now — and "add to playlist" on every cover and row. Both
surfaces share one list, read from the manifest, so they open instantly
with every node offline and no body is fetched until one is wanted.
Submenus expand in place rather than flying out: the account menu's
language list already does this, and a flyout has nowhere to go at 400px.
The tracklist under "remove a track" loads when it is expanded.
A name is typed into a field. Electron has no prompt — it throws.
Also splits the two playback failures: a decode failure belongs to that
file and keeps the bounded counter, a connection failure belongs to the
group and skips all of its queued tracks at once. Six dead tracks are
one more than the bound, which is where a playlist would otherwise stop.

playlists.js is IndexedDB, WebCrypto and a transport, and node has no
IndexedDB — so it is driven in Chrome against a node stubbed to record
what it was handed, which is also how what leaves the browser is
checked to be sealed.
Sync asks the node what it holds (user_blob_list) rather than comparing
against the merged watermark, which says nothing about that node: the
first version pushed every body on every sync. A tombstoned playlist's
body is deleted as each node is reached, or the quota fills with graves.
The database version and its stores stay in hub-client.js — two modules
opening one database at versions of their own is a VersionError thrown
at whichever runs second.

playlist-merge.js and playlist-crypto.js have no imports and are run by
their tests, which is the only real evidence this feature can have.
Two revision counters per playlist, not one: a rename on one device and
a track added on another both write n+1, and a single counter makes two
edits that do not overlap collide.
One Argon2 run at sign-in, two handles. The AES handle is imported
non-extractably, so nothing can be derived from it — hence a second
import of the same bytes as HKDF rather than a derivation.
Measured: ~270 bytes a track, deflate worth 4.5x on realistic data, so
the 1 MB body cap holds about 17000 tracks.

One row per playlist plus a manifest, so starring a track rewrites that
playlist rather than the whole collection. blob_enc is a BLOB, not
base64 TEXT: these run to hundreds of kilobytes.
user_id comes from the session and never from the message; kind is
validated against a pattern; every cap refuses with a stated reason
rather than truncating.
Additive, so MNP_MIN_SUPPORTED does not move — a 3.0 node answers
"unknown message type" and the client writes to the next one it reaches.

The player's queue could only be replaced: every onPlayQueue reset
tracks/order/pos together. It becomes one reducer (queue-ops.js) with
an `op`, because two appends batched into one tick cannot both read the
track count out of separate useStates.
A shared pop-up menu (menu.js) carries the three verbs, on right-click
and on a dots button. A track row is now a div holding two buttons: a
button cannot contain a button.
Found by the browser probe: both music wrappers took two arguments and
forwarded two, so every "add to queue" arrived as a plain play.

The 256 KB cap contradicted its own worked example; entries were also
missing `size`/`name`, without which a stored track cannot be fetched
at all. Storage becomes a manifest plus one blob per playlist,
compressed, so starring a track no longer rewrites the collection.
Adds the UI pass that was missing: the queue verbs, the menus, and the
one real code change behind them — the player's queue can today only
be replaced, not appended to.

Two live-reproduced bugs in Windows node start/stop, found sideloading the
0.14.0 build:
- node:start's crash-recovery step killed a service-mode daemon with
taskkill/CTRL_BREAK, both of which fail with "Access is denied" against a
process running under the Scheduled Task's own S4U logon session (a
different session from the Electron app's). The daemon it was meant to
replace just kept running, unreplaced, and schtasks /run on a task Windows
still considered Running was then a silent no-op too. Route through
winServiceTaskEnd() (schtasks /end) first, the way nodeServiceStop/
nodeServiceRestart already correctly do. service-mode.ps1 also now starts
the task right after registering it -- Register-ScheduledTask's own
AtStartup trigger does not run it immediately, so nothing was listening
until the next reboot.
- The Node page's Start button called node.start() with no arguments, so an
unlinked node (a fresh install, or one whose hub-side link was lost) could
never link on Start alone -- only create-group-page.js's own call passed
{hubUrl, username, token}. Reproduced on a fresh non-service install signed
in to the real hub: Start hung for ~105s and failed with "could not link",
pointing at a "Link Node" control that lives on Settings, not the Node
page (that message is fixed too).

`search_listed` is a per-group setting on the node, changed by a signed
operator op and carried in the sealed handshake ack. Search reads it after
the handshake and stops there: no index is fetched, cached or merged, in any
of the four views, and the page says how many groups it left out. The switch
is a "Search" section in the group's settings, shown to the operator.
Absent means listed, at every layer: roster default, ack default, and the
client only drops a group on an explicit `false` — so an upgrade or an older
node removes nothing from anyone's Search.
It is a listing preference and protects nothing: the node serves the same
index to Search and to the group page and cannot tell them apart, every
member lists the group by opening it, and a client that ignores the flag
lists it in Search too. Design §9.11 says so, so it is never described as
private. The cost is one handshake per unlisted group, because only the node
knows the setting.
Search also took `nodes[0]` twice — for the index and for the pooled
connection — the defect 4cce50f fixed on the group page only. One
`connectToGroup` now walks the list the same way: a refusal about this
browser stops, `not_hosted` or a failed connection moves on.

The router rendered `#/login`, `#/register` and `#/reset` before it checked
for a user. A browser signed in as one account, opening on a `#/login` left
in the address bar, drew the login form (prefilled by the browser with
another account) under a navigation bar and a sidebar already showing the
first account and its Administration entry.
`#/login` and `#/register` now need no one signed in, and a signed-in person
landing on either is sent home with `location.replace`, so Back does not lead
to the form again. `#/reset` stays reachable: that flow signs in half-way and
still has its progress and result to show.

Adding a large directory left the operator nothing to look at once they left
the Settings panel that started it, and nothing at all when it was added from
another machine. A band now sits above the music bar on every page: one row
per group with indexing under way, naming the root being walked, percent,
bytes and files, and the roots waiting their turn; "indexing finished" for a
few seconds at the end. A click opens the group's Settings, and × hides the
row until that group is idle.
Two sources feed it. On the node's own machine the desktop client polls the
loopback `GET /api/index-status` for every group, whatever the route. An
operator's group page forwards MNP `index_progress` pushes, resolving the
root from the roots table it opened; an ordinary member keeps the sidebar dot
only, and a page clears its row when it lets go of the group. Where both
describe a group, loopback wins.
Reconcile passes and watchdog bursts show only past 1 GB or 5 s, so a single
dropped file does not flash a bar. The logic lives in index-dock-model.js,
which has no imports and is tested under node. The dock publishes
`--index-dock-h` and the sidebar stops above it and the music bar.

`IndexProgress` said "scanning, this many bytes of that many" and nothing
more. A group's roots are walked one after another, so a second directory
added during a large scan showed as the bar jumping back to 0 %. It now also
carries the root being walked and its position in the roots table, the kind
of walk (scan, rescan, reconcile, watch), file counts, and the roots
waiting for the scan lock in order: queued by the initial scan, by a
retarget, and by a plug; dropped when a root is removed.
`GET /api/index-status` answers for every group at once, including a group
still in its initial scan, so a client can show indexing on any page. It
names roots: loopback only, like `current_dir`.
`index_progress` and the handshake ack gain the same counters, still naming
nothing (decision D3): the root is a position in the roots table the member
already opened from the sealed index, and the queue is a count. The pusher
keeps speaking while a root only waits for the lock.

A watchdog burst wrote the indexer's single `progress` directly. A file
dropped into a folder during a large scan added its size to the scan's
total, then cleared `scanning` when its own hash finished, so the progress
went blank with hours of hashing left. Bursts now keep their own counters,
shown only while no whole-root walk runs.
A plug rescan took no scan lock and walked its root beside an added root's
scan, both resetting the same counters and reading the drive in turn. It
now waits for the lock, and skips the rescan if the root was ejected or
removed while it waited, since the rescan drops the entries before it walks.

A root added from the client arrives over MNP, and _retarget_indexer
started the daemon's reload with the session's own _spawn. When that
session closed - a client reconnecting 47 s into the scan of a 900 GB
root - shutdown_tasks() cancelled the reload mid-scan, and the reload
queued behind it, without a line in the log. The new root was in
node.toml and in the indexer's set but never in the group's context; the
lock was free and nothing retried, so the node served the old roots table
for hours while reconcile hashed the whole drive as missed events. One
loopback reload fixed the live node in 9 ms.
_reload_config now runs the work in a node-owned task and awaits it
through asyncio.shield, so a caller that goes away only stops waiting; a
cancelled reload is logged. plug_root does the same for its rescan, which
drops the root's entries before walking the disk and so left the root
empty when its admin op's session closed.
The existing MNP test replaced _spawn with a list and could not cancel
anything; the new tests close the session for real and fail without this.

Adding a large directory to a running group made the reload await the
scan of the new root before putting the new RootSet in the group's
context, holding _reload_lock the whole time. For the hours a large drive
takes to hash, the node served the old set:
- a file request under the new root got None from entry_abs_path and the
handler died on None.exists() without replying;
- a writable/removable toggle answered with the live table, still the
old one, so the directory vanished from the operator's settings;
- reconcile saw every file the scan had not reached as a missed event and
hashed it again on the same executor, rewriting progress under the scan.
retarget now applies the set, the roots table and the watcher first, and
with wait=False scans the added roots in the background; the daemon swaps
ctx["roots"] before calling it. A scan lock shared by the initial scan,
added-root scans and reconcile makes the reconcile loop sit out a running
scan without backing off. Every transport site that resolves an entry
answers ROOT_NOT_SERVED instead of crashing, and a delete keeps the entry.

One derivation is 256 MB and a quarter to half a second of CPU (240 ms here,
485 ms on meshbay.org). All eleven call sites — sign-in, registration, the two
rehashes, passphrase change, reset and account deletion — ran it inline in an
async handler, so every one stopped the whole hub for that long: no request
served, no node socket read, no offer relayed. Measured on a local hub during
eight concurrent sign-ins, the worst `/v1/health` response went from 232 ms to
10 ms; the sign-ins themselves take the same time.
It could not simply go to a thread pool. Two concurrent `lanes=4` derivations
deadlock inside OpenSSL and never return, at no CPU — reproduced on
cryptography 50.0.x / OpenSSL 4.0.x both locally and on meshbay.org, while
`lanes=1` does not. `lanes` is part of every stored hash, so it is not ours to
change, and inline on the loop two derivations could never overlap, which is
the only reason production never hung.
So `auth.hash_password_off_loop` / `verify_password_off_loop` hand the work to
a dedicated executor with exactly one worker. Not a semaphore around
`to_thread`: a cancelled request would release its permit while its thread was
still deriving, and the next derivation would start beside it. One worker also
bounds Argon2's memory to one derivation whatever the number of callers.
`test_argon2_off_loop.py` reads every module for a direct call, pins the single
worker, runs four derivations and four sign-ins concurrently to completion, and
checks the loop keeps turning during a derivation; each fails with its guard
removed. CLAUDE.md and AV9 state the rule and the trap.

Passphrase sign-in locks per username: after `login.max_failures` wrong
passphrases (default 4) the name is refused with `429 account_locked` and a
`Retry-After` for `login.lockout_minutes` (default 60), without the passphrase
being checked. Both numbers are instance policy an admin sets from the panel;
zero failures turns it off. The per-IP limit bounds one address, and IPv6
gives every subscriber a /64 of them — an online guess targets an account, so
the account is what is counted.
- Counted by the name as typed, existing or not, so `login` stays uniform (M1).
The key is a hash: people type passphrases into the username field.
- The attempt is taken before the check in one `INSERT … ON CONFLICT DO UPDATE
… WHERE … RETURNING`, so a concurrent burst gets no more than the limit.
- Sign-in, passphrase change and account deletion count on the same row; the
last had no rate limit at all.
- A lockout refuses passphrase sign-in and nothing else: sessions, renewal and
device sign-in continue, and a reset code clears it (AV26). A session learns
its own lockout from `/v1/users/me`, and the passphrase change checks it
before re-wrapping any node's bundle — the hub accepts the new passphrase
only after the nodes have it.
The SPA now shows what the hub said. `loginAndRecover` threw "Login failed:
{json}", so `email_verification_required` never matched and was never shown;
the passphrase-change form rendered no error at all in its first phase.
The unauthenticated surface, reviewed route by route:
- No `/docs`, `/redoc` or `/openapi.json`, in the code. The Caddyfile hid them
on meshbay.org only; a packaged hub behind any other proxy published all three.
- The node socket's first message must arrive within ten seconds. It is
accepted before anyone is known, and an unbounded read is a connection any
stranger holds for free.
- `/v1/relays` answers 503 behind `relay.RELAYS_ENABLED`, as federation does:
nothing in the tree calls it and two of its routes take no account.
- `test_unauthenticated_surface.py` walks every route and fails on one without
an authentication dependency that is not listed with its reason.
Verified in Chrome against a local hub: the lockout and wrong-passphrase
messages, the admin section saving both lockout and mail limits, and the
passphrase change refused while locked. Not verified in Firefox (a running
instance blocks the headless one), nor the upsert's concurrency on PostgreSQL.

Every MHP route answers a stated 503. `federation.FEDERATION_ENABLED` is the
only thing that decides it, applied as a dependency on the router so the six
routes that exist and any added later are covered by construction — a gate you
have to remember to write in each handler is the shape C6 is the standing
lesson about.
The protocol is not what is wrong with it. What is wrong is that nothing has
ever run it: two hubs have never completed one authenticated request between
them. AV14 was two defects in the same path — an issuer signing with a key
bound before it was loaded, naming itself after the reference deployment
whatever the instance was called, and a verifier naming no audience for the
`aud` the issuer sets, which PyJWT refuses outright. Both stood for a month
behind a green suite, and both were found by reading rather than by running,
because a second implementation of a peer proves the protocol and nothing about
two machines.
Four of the six routes carry no authentication of their own — the MHP token is
the authentication — and two of those write, a directory push and a revocation.
That is the surface being closed until somebody stands up a second hub.
A constant and not a `hub_settings` row, deliberately: a switch in the admin
panel invites an operator to turn on a feature that has never worked between
two machines, where this takes an edit, a deploy, and reading the comment above
it. `/v1/hub/info` reports the state, because the `mhp_version` beside it would
otherwise be a claim the hub does not honour.
The protocol tests open the gate for their own duration and say why; the one
that runs with the flag as it ships asserts all six routes refuse. §7.6 states
the closure, §15.2 carries federation between two hubs as not built.

§15.3 gains the items the review found and did not close, each as what it is
rather than as a plan: the packaged install that has never been installed, QUIC
serving content outside every cap it does not implement, a relay registry
nothing calls, an unmetered third-party search, disk I/O on the node's event
loop, unbounded node announcements, and a migration chain exercised on a
database it does not ship on.
They are in the design rather than in a tracker because each is a sentence about
what the system currently is, and §15.3 is where the document already keeps
those. The seven that were closed this week are in §13.5b as AV20–AV25 and in
the sections they belong to.
CLAUDE.md gains the Firefox harness, which is the other kind of entry: eleven
errors at setup that look exactly like a regression, are not, and cost a full
diagnosis to place. `HOME` isolates the profile and not snap's single instance,
so any running Firefox blocks the headless probe, `--no-remote` and
`--new-instance` do not help, and a failed run leaves a process that blocks the
next. The chrome half covers the same geometry meanwhile.
