The audience split stopped a member's node credential from opening the hub API.
It did not stop the credential being *replayed to another node*: the MNP token
carried the member's whole group set and named no node, so a token handed to
node A's operator could be presented to node B the member also belongs to. That
does not read content on B — the handshake still requires proving node B's group
key, which the operator lacks — but it reaches B's pre-proof window and fetches
the member's *encrypted* keypair bundle for B (offline-attackable, bounded,
audited): a disclosure §2.4 says should not follow from hosting a member on A.
The token now names the node it is minted for (a `node` claim = that node's
Ed25519 key), and authorize_token refuses one that names a different key. The
client already knows the target node's key (from /v1/groups/{id}/nodes) and asks
for a token bound to it: POST /v1/nodes/mnp-token takes node_pk, and
transport.connect threads it (group-page, the connection pool and rewrap pass
n.pk_node; reconnect preserves it). A token that names no node is still
accepted, because the hub only mints one for the authenticated requester, so an
unbound token grants nothing across accounts — which also keeps non-binding
callers working with no churn.
Done before deploy, so it folds into the MNP 4.0 flag day rather than needing
its own. Docs: §5.2, register E10, MESHBAY_NODE_PROTOCOL.md §6.3.
test_handshake.py and test_mnp_token.py hold the binding (a token for node A is
refused by node B, accepted by node A; an unbound token still works); red
before, green after. common/node/hub suites green.

failed node-key link
Two defensive gaps turned a routine reset-and-reonboard into "impossible de
démarrer le node":
1. daemon._login_with_retry retried a 401 (node key not linked yet) but `raise`d
on every other status, so a 429 — the daemon's own 5s retries hitting the
sign-in rate limit — or a 502/503 while the hub restarts during a deploy
killed the process, and systemd crash-looped it. Those statuses (429, 5xx)
are now retried with a back-off that respects Retry-After, so a freshly
reset node stays alive (the operator needs it up to read its key) instead of
dying. A genuine 4xx (400/422) still raises.
2. create-group's linkNodeKey swallowed every error as "already linked or same
key" — but PUT /me/node_key is idempotent and returns 200 on a re-link, so
there was no benign error to hide: the catch only ever hid a real failure
(a rejected session, a bad key), letting the wizard proceed against a node
that looked linked but was not, which then could not authenticate. The link
failure now surfaces (detectNode shows it).
test_login_retry_is_resilient.py holds the retry behaviour (429/5xx retried,
Retry-After honoured, 401 stays alive, 400 still raises); red before, green
after. common/node/hub suites green.

The node-audience token (previous commit) is a change to what a peer must
present, so it is a MAJOR per the versioning rule (§5.6): a pre-4.0 client
presents its hub session token and a 4.0 node refuses it, and there is no
compatibility branch, because leaving one would keep a hub credential reachable
by every node (C6's lesson). So the floor moves with the version.
- MNP_VERSION 3.4 -> 4.0 and MNP_MIN_SUPPORTED 3.0 -> 4.0 (meshbay_common);
transport.js MNP_V/MNP_V_MIN -> 4.0 to match.
- MIN_CLIENT_VERSION 0.13.0 -> 0.16.0 so a stale desktop client is told to
update before connecting rather than meeting a handshake refusal it cannot
read; the browser reloads this build from the hub.
- Regenerate tests/golden/dispatch.json: the only change is the `v` the node
stamps on outbound messages, 3.4 -> 4.0 (56 cases, v field only).
- Document the split and the flag day: MESHBAY_DESIGN.md §5.2 (the handshake
token is the MNP-audience token), §5.6 (the 4.0 flag day), register E10 and
decision 23; MESHBAY_NODE_PROTOCOL.md §6.3 (authorize_token binds MNP_AUD)
and the wire-version banner.
Deploy is coordinated and atomic (common+hub+node+SPA together); a live
browser-to-node validation and the deploy itself remain. common (173), node
(1489, the pre-existing test_cli_golden argparse/prog artifact aside) and hub
(1471) suites all green.

session token
A member authenticated to a node in the MNP handshake with its hub *session*
token — scope=user, valid at the hub API for hours. A node operator is in the
threat model, so this handed them a live hub credential for the member: enough
to enumerate the member's other groups, act as them, and (before the previous
commit closed it) take the account over. The node genuinely needs a hub-signed
membership assertion, so the fix is to make that a separate credential that
opens nothing at the hub API.
Two audiences signed by the one hub key (meshbay_common/tokens.py):
- HUB_API_AUD — session tokens (login, device-auth, node-auth, refresh), used
for hub calls and signaling. decode_access_token now binds this audience, so
an MNP token cannot be replayed against the hub API.
- MNP_AUD — a short-lived token a member presents to a node and nothing else,
from POST /v1/nodes/mnp-token. authorize_token now binds this audience, so a
session token presented to a node is refused. This closes the disclosure.
The node's own self-decode (hub_client.py) reads its node token with
audience=HUB_API_AUD. The client fetches the MNP token inside transport.connect()
(and on every reconnect) using the session token, so callers are unchanged and
signaling keeps using the session token.
No regression to a long session: the MNP token is checked once, at the
handshake, before any proof — a film already playing is not re-authenticated, so
a 15-minute token does not interrupt a 4-hour film; reconnects refetch a fresh
one. Denylist and membership checks are unchanged (the MNP token carries
sub/jti/groups).
Tests: authorize_token refuses a session/no-audience token and accepts an MNP
token; the hub API refuses an MNP token; POST /v1/nodes/mnp-token is minted only
for a member's own session. Verified red-before/green-after; common, node and
hub suites green (the pre-existing test_cli_golden failure is an argparse/pytest
prog artifact unrelated to this change).
Still to do before deploy (B2): bump the MNP version and client.minimum so a
stale desktop client is told to update rather than getting a handshake refusal,
update docs/MESHBAY_DESIGN.md and MESHBAY_NODE_PROTOCOL.md, and validate against
a real node locally, then deploy hub+node+SPA atomically.

A member hands its hub access token to every node it connects to (the MNP
handshake), so a node operator holds a live bearer token for that member.
PATCH /v1/users/me {email} needed only that token, and the confirmation code
goes to the new address — so an operator could point the account's e-mail at
their own inbox, confirm it, and then use the passphrase-reset path to take the
account over. This is the immediate mitigation of that chain; the full fix
(a node-audience token distinct from the API session token) follows.
Changing the address now requires the passphrase-derived auth_key, verified
through the same throttle as a passphrase change or an account deletion — the
hub still never sees the passphrase. A PATCH that does not change the address is
unaffected. The profile page prompts for the passphrase and derives auth_key
with the existing MeshBayKeys.deriveAuthKey, as the delete and change-password
flows already do.
test_email_change_requires_passphrase.py: refused without / with a wrong
passphrase, proceeds with the right one, and a no-email PATCH still works; red
before, green after. test_mail_is_not_a_relay.py updated to pass the auth_key.

path
Two coupled gaps in the moderation surface (docs/MESHBAY_DESIGN.md §7.5):
admin_patch_group let a moderator set a group to "revoked", while the user
handler makes revoke admin-only; and a "revoked" set through either PATCH was
never broadcast to nodes — unlike POST /v1/admin/revoke and account deletion —
so it behaved like "suspended" on nodes while claiming to be the signed,
node-enforced state H4 promises.
PATCH now refuses "revoked" on both users and groups (400, pointing at
POST /v1/admin/revoke, which signs and broadcasts), a moderator setting a group
to revoked is refused with 403 as on the user handler, and moving an entity out
of "revoked" requires admin — a moderator flipping the hub row back to active
would only disagree with the nodes still enforcing the broadcast. Revoke has one
door and it broadcasts.
The admin SPA already revokes through POST /v1/admin/revoke, so this is not a
UI-visible change.
test_revoke_is_one_path.py holds the refusals and the working path; verified red
against the pre-fix admin.py and green after.

One Ed25519 key signs four kinds of token — user access, node access,
revocation broadcasts (no exp, no sub, and returned in the body of
POST /v1/admin/revoke and pushed to every node) and MHP federation tokens
(aud, sub=hub_id, no scope). decode_access_token required none of these, so a
hub-signed token with no exp was accepted and separation between the types
rested only on which fields each consumer happened to read.
Require exp, sub and scope, and reject a scope that is not one of the two
access scopes. A revocation or MHP token can no longer be mistaken for a
session, and no hub-signed token without an expiry is honoured.
A full RFC 5987 aud binding is deliberately not used: the node decodes its own
hub-issued token without passing audience, so adding aud would make every
already-deployed node reject its own token (InvalidAudienceError) — a
coordinated, node-breaking change. scope gives the same purpose separation
among the hub's own token types without it. This is non-breaking: every real
access token already carries exp, sub and scope, so no session is forced to
re-authenticate.
test_token_hardening.py holds the refusals (no exp, no scope, unknown scope, a
revocation token as bearer) and the paths that must keep working (a real login
token, a node token); verified red against the pre-fix auth.py and green after.

A node's authority and a hub role are different notions: what a node may do
is decided by its operator's roster pin on the node (NS4), while admin and
moderator are hub roles on a person's account, exercised from a browser with
a user-scoped token. The scope refusal was wired only onto require_user_scope
(group mutation), so require_admin and require_moderator accepted a
scope:"node" daemon token whenever the underlying account also held a hub
role. On a deployment where the operator is a hub admin and runs a node, the
daemon's in-memory token was therefore a full hub-admin credential — able to
revoke accounts and groups (signed, broadcast to every node), change instance
policy, and read the IP audit log.
Factor the refusal into _reject_node_scope(payload) and call it from
require_user_scope, require_moderator and require_admin alike, so a
node-scoped token is turned away with 403 on every privileged route.
test_node_scope_not_admin.py holds seven refusals, each asserting the same
account's user-scoped token still gets in; verified red against the pre-fix
deps.py and green after.

transport.js keeps the core (connection, reconnect, leases, dispatch).
Chat, media, admin, upload and device methods move, cut as text, into
transport-*.js scripts that hand a class of their own to extendTransport,
which copies each method onto MeshBayTransport.prototype; the codec,
roster checks, node pins and the rewrap fan-out move as they were. Both
shells load them after transport.js. Every prototype member, class
property and top-level function has the same source text as before.

goes from 49 modules / 386 KB gzip to 37 / 289 KB; opening Music now

dead node
The other half of the 4G failure. The page negotiated every group twice: the
sweep opened a connection, read the index and closed it, then the warm-up
opened the same group again. The sweep, the warm-up and the tiles each had a
concurrency ceiling of their own, and together they went past what the hub
admits per account. Whatever the hub refused was then reported as "node
unreachable" and remembered as down, which put that group last next time.
- Every connection goes through ConnectionPool, which holds the page's one
ceiling (six at once, sized for twenty groups on a phone) and keeps what
the sweep opened for the tiles. A visit costs one offer per group. A
refresh costs none for a connection that answers a four-second ping, and
a connection that died while the phone slept is replaced, not waited on.
- A connection whose index is being read is held against eviction. With
more groups than the pool keeps, it was otherwise the least recently used
one.
- Negotiations still under way when the page closes close what they get,
and a sweep cut short that way remembers nobody as down.
- transport.js sends an offer again on 429, 502 or 503, honouring
Retry-After, with jittered waits of about twenty seconds at worst. Search
counts each retry as progress. A 404, 403 or 504 still fails at once, so
a dead node costs no time.
The fan-out tests assumed a ceiling of three and were re-measured: four dead
groups of twelve now hold nothing back, even on a first visit. The pool and
the retry run as shipped code, lifted as text, against a fake clock. Each
guard was checked by removing it and seeing its test fail.

A phone on 4G found one of five groups missing from Search on half its
visits, and all but one on a fifth of them. Every offer that reached the node
was answered in about a second; the hub refused the others with 429 — 93 of
them in half an hour on meshbay.org, all from that phone, all to nodes that
were up. Two ceilings did it. Three pending offers per account was exactly
what one Search page dialled at once, so the first tile or reconnection beside
the sweep was refused. Thirty offers a minute per address and per node was
spent by four or five reloads of a page whose groups share one node.
Sized now against an account with twenty groups on three devices:
- 32 offers pending per account, across devices and nodes.
- A budget per account and per node, a burst of 120 refilled at two a
second. This is what bounds a member's cost to one machine (H6), and it
leaves their other nodes alone. Counted by account, because a mobile
carrier puts many subscribers behind one IPv4 address.
- 600 a minute per address and per node, as a coarse guard in front of
authentication only.
Both refusals carry Retry-After, which the browser now honours. The node's
own ceiling on peer sessions is unchanged; its comment no longer quotes the
old per-account number.

The list under "Invite by link" answered every ticket the group had ever
minted, so a link that somebody had already used sat there saying "used by
<name>" for the thirty days of KEEP_REDEEMED — beside the member row it had
just produced, and above the links that still wait for somebody, which are
the only ones there is anything to do about. The node's own `member list`
had never shown them: it selects `used_at IS NULL`.
The listing now selects `redeemed_by IS NULL`, and drops the `redeemed`
status and the `redeemed_by` field with it. The row itself still lives for
KEEP_REDEEMED, which is what lets a reload or a second tab of the invitation
page be answered rather than refused; its comment says that now instead of
naming a list it is no longer in.
The SPA filters too, because the desktop client's copy of this interface can
be newer than the hub it is signed into.

#/invite takes the link out of the address on load and keeps it in the
tab through registration and sign-in; joining is one click, only the
ticket goes to the hub, and the code goes only to the node the link
names once it has signed its challenge. Members tab gains "Invite by
link" (shared e-mail box, pending list, cancel both halves); home page
takes a pasted link. Browser probe drives the real app, signed out and in.

The node half called `unpin` after `revoke`, and an unpin takes no group:
it deletes the identity and every member row the account holds on this
node, and drops the stored keypair bundle with them. Taking somebody out
of one group took them out of all of them, silently. `revoke` is
group-scoped and is what withdraws the key.

A reconnection restarted the stream at the playhead, and that empties the
source buffer — spending the whole read-ahead at the one moment it was the
thing carrying the film. It carries on from the end of the buffer instead,
except where the buffer is short, the stream already ended, or a cast is
active: the receiver is fed from the wire and never had that buffer, so
resuming there would skip it forward by the lot.

A browser limits bytes, so a bound in seconds had to be sized for the
highest-bitrate file and every ordinary one then held a fraction of what
the same buffer would have taken. Floored at the old 90 s so nothing
pulls less than before, and walked up rather than declared. A refused
append now waits for an eviction instead of retrying on every tick.

A member row appears only when a code is consumed, so revoking someone
invited to the wrong group was refused for having no row — and the node's
refusal aborted the browser's removal before its hub half, leaving them a
member everywhere with a live code. Revoking now cancels unredeemed codes
for that group, and a node refusal no longer cancels the hub removal.

It was only the Node ID row's fallback, so it vanished the moment the node
announced itself — and was labelled Node ID when it did show. Own row, copy
button, and the profile's instructions no longer name the node dashboard
removed on 2026-09-01.
`.node-key` wraps: 44 base64 characters with no break opportunity pushed a
412px document to 417px, which unpins every sticky element on the page. The
width probe now measures the Overview table with a real key in it.

`.admin-table` column heads are `white-space: nowrap`, which meets a
translated string: "Username" is one word, "Nom d'utilisateur" is three,
uppercased with letter-spacing on top. The heads alone overflowed a 360px
window by 11px, and on Android an overflowing document takes every sticky
element with it.
11px was only what could be measured: the probe served no members, so the
table measured its headers and nothing else. With one realistic username
in it the same page overflowed by 248px, at 420px-wide windows too. The
cells get `word-break: break-word`, as `.file-name` already had.

The pass before this applied ruff's own fixes. These are the ones needing a
decision, and the point of doing them is that `ruff check .` now passes: a
linter reporting 98 known-acceptable findings reports nothing, because the next
real one arrives invisible.
**Lines over 100 (70).** Mostly wrapped where they stood. Two exceptions: the
aligned trailing comments in `protocol.py`'s message table were shortened rather
than wrapped, because wrapping one row of a table breaks the table; and in
`models.py` the column comments moved above their columns for the same reason.
**Imports below the first statement (14).** `csam.py` kept its FastAPI imports
under a section header halfway down the file; two node tests had a constant and
a `pytestmark` wedged between two import blocks. Moved, not suppressed.
**Bindings nothing reads (4).** Three in tests, where the call stays and only the
name goes — `_user(client, "listener")` is there to create the user, not to
return one. The fourth was in `revocation.py` and was not a lint finding at all:
`_connect_and_listen` opened an httpx stream to the WebSocket URL, did `pass`,
and then opened the real connection through the `websockets` library. One
pointless request per connect, left over from before that library was used
directly. Removed, and `httpx` with it.
**`l` as a name (4)**, **semicolons (6)** in the POC spikes, and the rest.
2893 passed, the same count as the two commits before it.
`meshbay_node/revocation.py` is worth a decision separately: 154 lines that
nothing imports, superseded by `hub_client.maintain_ws`'s `on_revocation`. This
commit only stopped it failing the linter.

`ruff check .` had gone unrun long enough to report 568 errors, which is the
same as having no linter: the next real finding would have been invisible in the
noise. This is the 521 it fixes by itself, in 173 files, and nothing else — the
98 it cannot fix are the next commit.
What actually changed: import sorting (225), imports nobody used (87, none of
them a re-export — no `__init__.py` is touched, which was the one way this could
have broken an import elsewhere), `datetime.timezone.utc` to `datetime.UTC` (69)
and `asyncio.TimeoutError` to `TimeoutError` (18), both plain aliases on the 3.12
this project requires, `Optional[X]` to `X | None` (24), and f-strings with
nothing to interpolate (19).
Checked rather than assumed: every module in the three packages still imports,
and the suite is 2893 passed — the same count, test for test, as the merge
before it.

The grid's unit is an album, so a track whose artist tag is empty was
drawn nowhere — while `empty` counted it and stayed false, so no message
appeared either. An untagged library rendered a toolbar over a blank
page, with every track one mode-switch away and nothing saying so.
It gets a card, the same shape the singleton folding already mints. No
cover is looked up for it, or for any album this file invented: the
release name is one the browser wrote, and the request cannot match.
music_untagged_probe.py renders the real grid and reads the page back.

_reconnectLoop re-did the handshake and nothing else, so a page kept
whatever it last saw until someone reloaded it. That is invisible until
the node restarts: it rebuilds its index from index_cache.db, which
holds no enrichment, and Music is the one app whose enrichment is
persisted nowhere — for the length of the re-read pass it serves tracks
with no artist, and the album grid drew nothing.
onReconnected was one slot the video player took on open and cleared on
close; it is a listener set now, and carries the fresh ack.
docs/MESHBAY_DESIGN.md §15.3 records the two defects found alongside and
not fixed here.

One conflict, in §15.3's open list, and it was two changes agreeing rather than
disagreeing: this side removed the rows for the third-party search bound and the
node-announcement bound because both are now built (AV27, AV28), while the other
side kept them and added a new one. Resolved by keeping what is genuinely still
open — per-device revocation having no CLI — and leaving the two closed.
`webrtc_server.py` merged without conflict but the two sides met inside one
function: `_upload_chunk` gained the operator's `max_upload_gb` ceiling from
there and the per-group lock and `off_disk` calls from here. Read back rather
than trusted: the operator's ceiling now sits inside the critical section that
keeps chunk ordering, and the unlink beside it goes to the disk thread with
everything else.
2893 passed. The twelve `test_sticky_header.py[firefox]` setup errors are the
open Firefox on this machine, as before.

Was a 4 GB constant in webrtc_server.py, the same on a small board and on
a machine holding a library. Now max_upload_gb in node.toml, on the Node
page and via `meshbay-node transfers max-size`, read from the transport
context per chunk so a change reaches an upload already running.
MESHBAY_DESIGN.md §6.4; §15.3 records a defect found beside it.

`BROWSER_INCOMPATIBLE_AUDIO_EXTS` named the two formats no browser decodes and
was read by nothing. The player asked for `.wma` and `.mpc` and no others, and
`music-player.js` called itself "kept in sync with the node's" constant — so the
entire restriction lived in the caller, and a member's own message is not the
caller.
What that let through: this converts a whole file and holds a transcode slot
shared with video streaming while it runs. One message naming a two-hour film
spends minutes of the operator's CPU and a slot every other viewer is queued
behind. `AUDIO_TRANSCODE_MAX_BYTES` catches the result, after the work is done;
only the extension catches the work.
The client comment now says what it is — an optimisation that saves asking for a
refusal — rather than implying it is the rule.
Two tests: a film is refused before ffmpeg is reached, and a WMA still passes,
because a gate that refuses everything is not a gate.

**A free-text TMDB search spends the operator's credential.** TMDB rates it, and
the automatic matching every member sees runs on the same one, so a member
holding down the search box — or a script doing it — degrades the library for
everyone and empties a quota the operator pays for. The handler had no ceiling of
any kind, where link previews beside it carry two. §6.5's standing rule is a bound
and a named adversary in the same commit; this arrived with neither.
Per member and not per connection, unlike link previews: three tabs is one
person, and a ceiling a tab can multiply is not a ceiling. Kept in the group
context, so a reconnect does not reset it — a client that drops its channel
between searches would otherwise have no ceiling at all. The node-wide window
stays too, because the two answer different questions: one keeps a member from
spending everyone's quota, the other keeps a roomful of them from doing it
together. Ten a minute each, thirty for the node — a search every six seconds,
sustained, is past what anyone types.
The refusal is an error rather than an empty list. An empty list is what "no such
film" looks like, and telling somebody their film is unknown when the node simply
declined to ask is a worse answer than the truth; `video-app.js` already puts
`detail` on screen.
**How many node keys one account may announce.** Each is a row in `nodes` plus a
row in the IP log, and the IP log is kept for a year, so an account in a loop
writes a year of storage on the operator's disk having paid only for signatures.
M8 settled whose key it is and said nothing about how many. Ten: a node is a
machine left running, and an account wanting an eleventh *identity* rather than
an eleventh machine is the case this refuses.
Counted only where a row is added. Applied to every announce it would freeze the
address of every node an account already runs the moment it reached the limit,
and a node that cannot re-announce is unreachable after its ISP renumbers it —
an outage caused by the protection. There is a test for exactly that.
Both tests are two accounts, per §13.5b: a ceiling one person can exhaust for
another is not a ceiling but a queue, and a ceiling shared between accounts would
let one member stop every other from bringing a machine online. Checked by
removing each ceiling: seven tests fail.
`test_season_and_search_requests.py` built its session without a `_user_id`,
which production guarantees — `_dispatch_message` refuses every message until the
handshake settles it. The fixture was narrower than the node, so it could not
exercise a per-member bound at all; it has one now.
Twelve `test_sticky_header.py[firefox]` setup errors in a full run here: Firefox
is open on this machine, the trap CLAUDE.md describes, and its twelve `[chrome]`
tests covering the same geometry pass.

`group_indexes` was an IndexedDB store holding a decrypted copy of each group's
index — every file's name, path, size, hash and uploader — written on every index
and on every delta, from three call sites.
It was the cross-group search of Phase 10b: `doSearch` read `getAllCachedIndexes`
and searched those records instead of dialling anything. On 2026-08-28 Search
began dialling the nodes, and that commit removed the reader and left the writers.
Since then the browser has gone on building a cleartext file listing that nothing
consulted, that no sign-out removed — the key database is a different one — and
that grew with every group ever opened. L7, at rest: kept code that nothing calls
does not sit still.
Drawing a group's files while its node is unreachable is the only thing such a
cache buys, and it is not wanted: a listing that cannot be opened is worse than an
honest absence. So there is nothing to read it with, and the writers go.
The store stays in the schema and is emptied instead. Dropping it needs a version
bump, a version bump is an upgrade another tab can block, and playlists share this
database — so the tidier change is the one with a failure mode. `purgeGroupIndexCache`
runs once per browser behind a flag, which clears what is already on people's
machines; a browser that refuses storage simply runs it again, which is harmless
because it is idempotent.
Three guards, each checked by reintroducing the fault: only `openDB` and the purge
may touch the store, the purge may only clear it, and the purge must actually be
called at start-up — a purge nobody calls is the same defect wearing the opposite
hat.
`test_sticky_header.py[firefox]` reports twelve setup errors in a full run here.
A Firefox instance is open on this machine, which is the trap CLAUDE.md describes;
the same twelve appear with these changes stashed, and the `[chrome]` half of the
same file, covering the same geometry, is clean.

The per-feature design notes were merged into docs/MESHBAY_DESIGN.md and
deleted from the tree on 2026-09-11, but ~230 comments across the three
packages still named them — usually written `docs/musicbay.md §3.2`, as
though the file were still in docs/. A reader had to know §16 existed to
resolve any of them. They now name the section directly.
Every mapping comes from §16, the concordance, which already records where
each old section landed: musicbay -> §9.8, mediacenter -> §9.7 for the
Videos app and §6.5 where the subject is derived data, photos -> §9.9,
auth-confirm -> §3.6, refactoring-search -> §9.11, invite-pairing-v1 ->
§3.4, per-node-identity-v1 -> §3.2, captcha -> §7.7, chat-sender-keys ->
§4.5, apps/refactor-groups -> §9.1–§9.4, desktop-client-v1 per section.
Bare citations of the same documents (`draft-v6 §2.11`, `§4.8`, `§3.4`)
are retargeted too: those collide with real section numbers in the design
document, so leaving them would have been worse than the named form.
Four cases the concordance does not cover, each decided rather than guessed:
Sub-item references into documents that no longer exist — mediacenter's
`§3.3 row 4`, `§3.4b/c`, `apps.md §3b` — name rows and sub-items §9.7 and
§9.2 do not reproduce. The module-level citation stays; the sub-item
pointer is dropped.
The V-findings keep their labels but lose the dead `§10.1/` prefix.
§13.8 lists V1–V13 as per-application open items, which is not what the
labels mean in these comments, so pointing them at §13.8 would have been
a false citation.
`apps.md §5`'s virtualization requirement has no counterpart anywhere in
the design document. The requirement is stated in the comment itself, so
the citation is dropped rather than aimed at a section that does not say
it.
Comments that attributed a *sentence* to an old note — musicbay's "several
thousand files" example, its "what got measured" note, its measured
~11%/~26% cover-art figures, the "original no root, whole shared tree"
call — state the fact without attribution now. §9.8 does not contain those
sentences and citing it for them would have been wrong.
CLAUDE.md's "a reference to a document that no longer exists" row now says
the concordance is for git history and out-of-tree material; the code cites
sections directly.
Verified: 2851 passed, 4 skipped. The 12 errors in the run are the Firefox
leg of test_sticky_header.py's browser harness, which is broken at the
browser level on this machine — headless Firefox (snap) dies with
`[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer`, renders
nothing, and the probe exits `{"error": "no measurement"}` after its full
90s wait. Chrome runs the same 12 assertions in 3.2s and passes. Nothing
here can affect it: every changed line in style.css is inside a comment.
Also checked: ast.parse on every changed .py, `node --check` on every
changed .js, the /* */ balance in style.css, and that no changed line
exceeds the width its file already used.
