The dismiss-on-scroll listener is on the capture phase, because `scroll`
does not bubble — so it also heard the menu scrolling itself, and a long
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.

Folders were always ordered by name, whatever the column and direction, so
reversing the name sort or sorting by size moved only the files. A folder's
size is what it holds and its date its newest file; ties go to the name.

Into the folder on screen, under the Upload button's rule. A name already
there, or one the node would refuse, cancels the whole drop with a message.
Folders are recreated level by level; files go out a few at a time. The
in-flight upload guard is keyed by folder and name.

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.

`add_email_verification` wrote PostgreSQL's `(now() at time zone 'utc')` as a
literal server default, where every other migration in the chain uses
`sa.func.now()` and lets the dialect render it. On SQLite that is
`sqlite3.OperationalError: near "at": syntax error` — so `meshbay-hub migrate`
could not reach head on the database the suite and the documented local-hub
workflow both use.
Which is how it survived: the only test that ran alembic at all stopped at
`c3d4e5f6a7b8`, the revision immediately before it. The two newest migrations —
email verification, and the mail quota committed two days ago — had been run by
exactly one thing, a production deploy, and the newest by nothing at all.
`test_migrations_reach_head.py` upgrades to head and compares what that built
against `Base.metadata`, both directions: a column in the models and in no
migration never reaches production, and one in the migrations and in no model is
a rename abandoned halfway. Both tests fail on the unfixed migration with the
error above; the drift half was checked by adding a model column on purpose and
watching it be named. The schemas agree today.
It still does not check PostgreSQL-only behaviour — a default, an index type or
a constraint one dialect accepts and the other refuses. Running the chain
somewhere beats running it nowhere, and is not the same as running it where it
ships.

group's hosts are its members'
Two checks that were not performed, in the same shape: something true of the
public case, written so it did not apply to the rest.
**Signaling.** The membership check read `if node_group_ids:`, so an empty set
skipped it — membership, group status and the public-group gate together — and
the offer was relayed. Since AV1 made an empty claim mean "no groups" rather
than "all of my owner's", that is the *normal* registration of a node hosting
nothing: the unconfigured node left running, the machine in this register's
founding incident, and the one least able to absorb the work. Each offer makes
it allocate an RTCPeerConnection and gather ICE, 30 a minute, which is H6
restored in exactly the case AV1 made common. It is refused now. Nothing
legitimate is lost: such a node refuses the handshake anyway — `group_id` is
mandatory (M1) and a node with no group key refuses (NS8) — so this declines
work the node would decline one step later at its own expense.
**The node list.** `GET /v1/groups/{id}/nodes` checked membership only for a
public group with public groups switched off. A private one answered any
authenticated account that knew the id — which an ex-member knows for ever —
with the ids and public keys of the machines hosting it. §7.4 already stated the
property for the public case. Membership is required now unless the group is
public and public groups are on. Nothing needs the list before joining: an open
join writes the membership row first, and an invitation registers the invitee's
when the code is created, both checked before making the change.
`test_webrtc_signaling_roundtrip` had to be repaired, and is the finding
restated: it registered a node in `_connected_nodes` and never in
`_node_groups`, so it drove the relay through the hole rather than through the
door — the check it routed around was the defect. It now registers the group a
real node registers.
§7.2 and §7.3 gain the rules, the register AV24 and AV25, and
test_availability_between_members.py two cases that fail on the property
against the previous source.

A chat message is the plainest member-supplied write there is: the node stores
it in `chat.db`, where nothing expires it — retention is a manual command
(§6.6) — relays it to every other connected member, and has the hub write a
notification for every member of the group. Nothing bounded any of it. The only
ceiling was the DataChannel frame, 64 MB once the handshake is done, so one
member in a loop filled the operator's disk and saturated everyone else's
connection, and the node's answer to each message was `ack`.
Uploads, the other member-supplied write, have carried a filename allowlist,
strict chunk ordering, a no-overwrite rule and a 4 GB cap since C5a — because
somebody asked what one member costs the others on that path. Nobody had asked
it on this one.
Two bounds, for the two halves of the question: **64 KB of ciphertext** for what
one message may cost, and **60 a minute per account per group** for how often
one member may impose it. Both are checked before anything is stored or relayed;
a refusal names itself and is audited, so "why is my disk full" has an answer.
The rate is keyed by account, not by connection: a second tab does not make
anyone type faster, and keying on the session would hand a script one budget per
socket it opens.
No node-wide ceiling beside it, deliberately. The link-preview limiter has one
because a preview spends the *node's* egress and its third-party quota, which is
one shared thing; a chat message spends the sender's own group, and a node-wide
ceiling would let a busy group silence a quiet one — this same defect one level
up. The last test in the new file is that property: a member at their limit has
not spent anybody else's.
Two things stay open on purpose and are named rather than quietly done:
retention still keeps everything, because a default that deletes people's
history is not a review's call; and the composer still offers to send an
oversized message, so this is §6.4's pattern with only the node half built.
§6.6 gains the rule, §13.5b the label — AV20, with AV21–AV23 registering the
three fixes this week that closed the same kind of gap elsewhere.

`_is_node_admin()` is `self._user_id == node_user_id`, and `_user_id` is the
`sub` of a JWT the hub issued. Six node-wide controls were gated on that alone:
`node_status` — which lists every group on the machine with each root's
**absolute path** — plus `node_settings_set`, `roster_read`, `denylist_read`,
`denylist_clear` and `node_reload`.
So the answer to "are you the operator of this node" was "the hub says so",
which NS4 and M3 rule out in as many words: operator authority comes from the
node's roster and from nowhere else, and asking the hub is how the hub installs
itself as node administrator. The reach is bounded — a completed handshake also
needs the group key — but an active hub obtains one legitimately in an
open-join group, which §3.5 concedes, and from there it could read the
operator's directory layout or clear the denylist, which is the persisted
revocation H4 exists to keep.
`_operator_device()` requires both halves now: the account is the one the node
belongs to, *and* the device on this connection has proved a key the roster
holds as an operator. `device_hello` is signed over a transcript naming the
node, the group and this connection's nonce, and `operator_pks()` is rebuilt
from the roster on each call, so an unpinned browser and a revoked one are both
refused at once. The hub holds no user keys and cannot countersign a device.
Keeping the account check as well is deliberate: dropping it would widen these
node-wide controls to any paired operator of any group on the machine, which is
a separate decision. `_is_node_admin()` stays as what it is in the handshake
ack — a hint telling a client whether to offer the Node page — and says so.
Nothing changes for a paired operator: `device_hello` runs unconditionally
after the ack, and anyone using the Node page's controls is already paired,
since `root_add` and every other signed op has always verified against
`operator_pks()`. A browser that never paired now reads nothing there, which is
the state in which it could already write nothing.
test_node_status.py's fixture set the account and not the device, which is how
it went on passing; it now wires the device the way `device_hello` leaves it.
The adversary itself is in test_security_regressions.py — a token naming the
owner's account with no proved device, which the previous source answered with
`node_status_ack`.

`_do_file_request` read `tr` as a boolean. Present meant "this is a leased
transfer, skip the leaseless ceiling", and nothing asked whether this node had
ever granted such a lease — `slots.touch(tr)` was called beside it and its
answer, `False` if it is not granted, was discarded. So any non-empty string
bought the whole library with no ceiling of any kind: not the per-member cap,
not the node-wide one, not the leaseless bound that exists to bound a client
claiming to be browsing. The queue held only the clients that chose to wait.
`_lease_of` decides it now, and the three answers differ on purpose:
- **granted**, and of *this* session — served, and touched so the sweeper
does not reclaim a transfer that is plainly moving. The session is checked
as well as the id, because touching another connection's lease refreshed
its idle timer.
- **queued** — refused with `lease_not_granted`, on the upload path too,
before anything reaches the operator's disk. A member reading while queued
is the cap not applying.
- **unknown** — bounded by the leaseless ceiling rather than refused. That is
also what a reconnect looks like from here, where the session's leases died
with the old connection and the client is re-opening them, and it leaves
the residual §5.5 already states: a client that lies gets that bound's
worth of files at a time, not the group. Noted once per connection so the
residual is visible rather than merely documented.
Nothing changes for the shipped client: the transfer store awaits
`lease.acquire()` before it reads a byte, so the refused case is one it never
enters. §5.5 gains a paragraph saying the node decides which of the two a
request is — the document described the accounting without ever saying it was
enforced, which is how it came not to be.
`test_lease_enforcement.py` drives the real handlers over a real index; six of
its nine cases fail against the previous source, each on the property.

asyncio keeps only a weak reference to a task, so a coroutine started with
`asyncio.ensure_future(...)` whose result is discarded can be collected while
it is still running: the loop logs "Task was destroyed but it is pending!" and
the work simply does not happen. No error reaches the caller, and what is lost
is whatever that coroutine was in the middle of.
The node already had a guard for this, written after an abandoned stream task
lost a transcode slot for good — and it read one file, `webrtc_server.py`,
because that is where the defect was found. Outside that file there were
nineteen sites: the hub's `chat_notify` (a notification for every member of a
group), the indexer's debounce (every real-time index update), eleven in
`daemon.py` including the SIGHUP reload and each enrichment pass, two in
`ops.py`, and five in the loopback API.
`meshbay_common.background.spawn()` is the one door. It holds the task, drops
it when it finishes, and logs what it raised under the coroutine's own name —
an exception in a task nobody awaits was otherwise reported by asyncio at
collection time, out of context or not at all. A peer session's `_spawn` stays
as it is: that one can also *cancel* what it holds, which a module-level holder
cannot, because a session ends and a process does not.
`test_background_tasks.py` walks every package's source and refuses a discarded
handle. It parses rather than greps, so an assignment, a comprehension or an
await is not mistaken for one, and it was checked against a deliberate
reintroduction. A guard that stops at the edge of the file where the bug was
found is a guard against that bug, not against its class.

`_register_uploader` walked the index for the entry it had just written, at a
moment when no such entry can exist: the file was a `.part` until the rename on
the line above, which is not indexable, and the watchdog that will index it
debounces for two seconds and then hashes. The walk matched nothing, silently,
so every uploaded file in every group was owned by nobody — and `file_delete`
refuses a caller with no admin authority when the entry records no uploader, so
a member could not delete what they had just sent. MESHBAY_DESIGN.md §5.4
grants that to any non-revoked device of the uploading account.
The record is now written when the last chunk lands (`indexer.record_upload`)
and the entry is stamped from it in `_hash_or_cached`, the one funnel every
entry passes through — initial scan, watchdog, reconcile and replug alike. It
lives in the index cache rather than on the entry alone, because the index is
rebuilt from disk at every start and an owner the node forgets on restart is a
right quietly taken away. It is validated against a live `stat()`, so whatever
later occupies that path inherits nothing; and `_rescan_root`'s carry-over no
longer copies over it, or memory would beat the durable record.
§5.4 also claimed ownership was *provable* — a transcript the uploader signs,
stored with the entry. No such signature has ever existed; `meshbay:upload:v1`
in the code is the groupbox purpose that seals the envelope. The section now
states what the code does, and the transcript is an open item in §15.3.
`test_upload_attribution.py` drives the real handler and a real indexer across
that seam. Against the previous source its two positive cases fail on the
property, not on a missing method — an upload, then a rebuild from disk, then
a different file at the same path inheriting nothing.

`ExecStartPre` ran `alembic -c /opt/meshbay-hub/migrations/alembic.ini upgrade
head`. The build does stage that file, so the path existed and the contents
were wrong: `alembic.ini` resolves `script_location` with `%(here)s`, so the
copy pointed at `/opt/meshbay-hub/migrations/src/meshbay_hub/db/migrations` —
which nothing installs, because the migrations ship inside `meshbay_hub`, in
the shared venv.
`ExecStartPre` failing stops the unit. A hub installed from the RPM or the DEB
could not start at all, and nothing noticed because the one live deployment
was assembled by hand — the same shape as the node unit that carried `User=`
into the user unit directory.
The same `%(here)s` trap was already found once on the server, where a stray
`alembic.ini` resolved to a month-old snapshot of the tree. Twice is a trap
rather than an accident, so the fix is that the path is no longer written down
anywhere: `meshbay-hub migrate` asks the installed package where its own
migrations are, which is correct for the RPM, the DEB, a venv and a checkout.
The build stages no `alembic.ini`; the repo keeps its own for `alembic
revision` and for deploy scripts that already work.
`env.py` now prefers a URL the caller resolved over re-reading the environment
itself, so `migrate --config` connects with exactly the string the server
will — one resolution, not two that agree until they do not.
Six tests, three of which fail against the unit as it was. They read the
directives rather than the file, because searching the whole thing finds the
comment explaining a directive and calls that the directive.

The figure was a line beside the settings form, which is where it is changed
and not where it is watched. It sits with the other live figures under
Statistics now — four cards and, above them, a banner saying which of the two
ceilings has fallen. The two states are not the same to whoever is reading:
one means newcomers are turned away, the other means somebody locked out of
their account cannot get back in. The settings block keeps a line pointing at
it.
And an operator no longer has to be looking. When a global ceiling is reached
the administrators are notified — in `mail.py`, in its own session, never
raising, because this runs while a request is being refused and an alert that
fails must not turn a refusal into a 500. Once per hour, keyed on a row
rather than a flag in memory: a flood is what spends the budget, so one alert
per refusal would bury the message under its own cause, and a hub that is
refusing mail is a hub somebody is about to restart.
`/v1/admin/mail` gains `general_exhausted` and `all_exhausted` rather than
leaving the panel to compare two numbers.
Labels in all ten catalogues; `.warn-msg` for the middle state, on the
`--warn` token both themes already define.

AV16 the allowance that survives a restart and that an operator can see and
change; AV17 the single worker.
And a lesson that cost a full suite run: `node --check` reports success on a
module-syntax error. An unclosed `.map(` inside a tagged template came back
clean four times. `test_spa_syntax.py` says exactly this in its own docstring
— copying to `.mjs` is what forces the module parser — and the reflex still
reached for `node --check`.

`_connected_nodes`, `_node_groups`, `_webrtc_answers` and the relay registry
are per-process dictionaries. With two workers a node registers in one and
the WebRTC offers for it arrive at the other, so the symptom is a node that
is intermittently offline for half its members — which reads as a network
problem, a NAT problem, anything but a configuration line.
`server.workers` has always defaulted to 1 and the constraint was written
down nowhere. One line at startup, and a function rather than an inline check
so it can be tested.

They were constants in two modules, so an operator could not touch them
without editing code and redeploying — and the hour a budget runs out is not
when anyone wants to do that.
`[mail]` in hub.toml carries the defaults; the live values live in
`hub_settings`, read at each use. A missing row falls back to what the
configuration file says, so an instance that never opens the panel behaves as
its file describes. The panel sends only what changed, the hub clamps each
value to a stated range and refuses a key it does not know, and the response
is what gets rendered — so a clamped value is never shown as stored.
`GET /v1/admin/mail` is the other half. There was no way to see any of this:
a refusal was a line in the journal, so an instance that had stopped sending
sign-up codes looked, from the panel, exactly like one with no sign-ups. It
reports the hour's use, what is left for sign-ups, and what is left for
recovery — the difference between those two being the reserved share made
visible.
Labels in all ten catalogues.

Two dicts in `mail.py` held the budget, so every deploy handed out a fresh
one — and this hub is deployed several times a day. A bound a restart forgets
is not a bound, for the reason the denylist is persisted rather than held in
memory (S3). It is a `mail_quota` table now, one row per counter, the
recipient hashed so the table does not become a list of plaintext addresses.
The counting moves with it, into an async `reserve` that has a session, and
`send_off_loop` is the one door it stands in. `_send` keeps the purpose
allow-list: that half needs no state, and it is what stops anything which
puts a message on the wire from naming a reason this hub does not send for.
The caller owns the commit, so a request that fails afterwards is not charged
for mail nobody received.
`hourly_reserved_for_recovery` is new. A flood of sign-ups used to be able to
spend the whole hour and lock out the person waiting on a passphrase reset;
registration and address changes may now spend only the unreserved share.
Values changed as agreed: 10 messages a day to one recipient, 300 s between
two reset codes. The address-change ceiling and its cooldown were two bounds
on one thing — 3 a day and 60 s apart — and collapse into one 48-hour delay.
Asking again for the address already pending is exempt: it reaches no new
recipient, that recipient is bounded anyway, and without the exemption a typo
locked the account out of correcting it for two days.

AV13 the mail gate, AV14 the MHP audience and the hub's own identity, AV15
the shape check on the unauthenticated blocklist endpoints. §13.5b also
records the auto-block threshold as an open decision rather than a defect.
Two lessons, both about tests.
A fixture narrower than production tests the fixture — and when it writes down
*why* it has to be narrow, that is a bug report nobody filed. Two test helpers
described the federation defects accurately, in comments, while routing
around them.
And a global's state is not a given, in a test least of all. One assertion —
that a refusal never logs the address — took three attempts, each passing
alone and failing in the full run, for three different reasons: caplog saw
nothing because the app configures logging, then a handler saw nothing
because an earlier test raised the logger's level, then because `disabled`

`GET /v1/blocklist` takes no authentication — a node syncs it at startup —
and had no ceiling on `limit`, so anyone could ask for the table in one query,
repeatedly. `GET /v1/blocklist/check` took any string of any length straight
into a primary-key lookup, unmetered.
Not changed, and worth a decision rather than a quiet edit:
`AUTO_BLOCK_THRESHOLD` is 3. Three distinct accounts blocking a hash adds it
to the list every node enforces, network-wide, automatically, with manual
admin removal the only undo. Far better than the anonymous version it
replaced, and still a censorship primitive an attacker buys for three email
addresses. §13.5b records the option — count only accounts more than a day
old, which costs a patient attacker a day and an honest reporter nothing.

Federation has never worked between two hubs, and the tests said so without
anyone reading it that way.
`federation.py` did `from meshbay_hub.auth import _hub_id, _hub_sk_pem` at
import — which is before `load_hub_keypair` runs. So it held the key as
`None` and the identity as the module default: `_issue_mhp_token` could only
raise, and `/mhp/info`, the directory export and every token announced this
instance as `meshbay.org` whatever it was configured as. Read through
accessors now, at call time.
And `_verify_mhp_token` named no audience while `_issue_mhp_token` sets one.
PyJWT refuses a token carrying `aud` when decode is given none, so every
token this hub issues was rejected by every hub running this code. Naming the
audience fixes that and makes the binding real: a token minted for one peer
is refused by another, which is what stops a captured request being replayed
at a third hub. The comment claiming audience binding was unavailable because
"the sending side is unbuilt" was describing a function four lines below it.
Both were already written down. `test_federation.py` built envelopes by hand
without an `aud`; `test_public_groups_toggle.py` signed its own token with a
comment saying `_issue_mhp_token` "binds `_hub_sk_pem` at import time, before
the lifespan loads it, so it cannot be used from a test", and another saying
PyJWT rejects a token carrying `aud` when decode is given none. Both
observations were exactly right, and both were treated as facts to route
around. When a test has to work around the code to run, the thing it worked
around is the finding. Those helpers now go through the real issuer, and two
tests pin the identity and the audience refusal.

The previous commit metered the paths that send mail. It was not enough, and
saying it was would have been wrong: a 60-second cooldown per account still
allows one stranger a minute — 1440 a day — and registration is open, so
"per account" is a bound an attacker buys more of. And there was a third door
nobody had counted.
POST /v1/users/register an address nobody has verified
PATCH /v1/users/me an address nobody has verified, signed in
POST /v1/users/password/reset only the address already on file
POST /v1/groups/{id}/invite-notify only a registered member's address
The widest was the register *resend* branch: no token, no captcha, and the
username and address are the caller's own from a moment ago — registering a
victim's address once bought the right to mail them at the endpoint's rate
limit for as long as the account stayed pending.
So the bound moves into `mail.py`, where every message passes one function.
`purpose` is keyword-required and checked against a closed list, so a helper
that names anything else does not send and one that names nothing is a
TypeError rather than an unrestricted send. Under it:
- a bound per **recipient**, across every purpose, account and endpoint —
what a person being mail-bombed actually experiences, and the only bound
that describes it. Keyed on a hash, because this would otherwise be the
one place in the hub holding plaintext addresses in memory (S2)
- an instance-wide hourly ceiling, which cannot be bought with more accounts
- a cooldown on the resend branch, a cooldown and a daily ceiling on the
address change, and the IP-log entry that endpoint never wrote — alone
among the ones that mail
The ceiling on address changes counts IP-log rows, not EmailVerification: the
handler deletes this account's unverified rows before writing a new one, so
counting those counts one, always. Which is what the first version of it did.
Refusals never carry the address: that line goes to the journal.
