Review of the Phase 1 commit found the RO/RW model sound but three paths
unfinished, each of which broke the flow the phase exists to deliver. Plus
29 test failures it introduced and no coverage for anything it added.
Uploads went to the wrong directory. The node read a `root` field on
file_upload that no client ever sent, so every upload landed in the first
writable root while the Files toolbar offered its button based on the root
being browsed — with two writable roots, uploading from one wrote into the
other. Files now names the root it is showing; Chat names one chosen in the
shell (an operator-configured directory arrives in Phase 2); the node refuses
an unknown name rather than falling back, and refuses read-only and ejected
roots by code.
Shared directories were unreachable on the web. The table read its roots
only from the loopback API, which resolves to "not available" in a browser,
so the section rendered for nobody there — while the Uploads controls it
replaced had worked — and the transport.updateRoot/ejectRoot/plugRoot methods
beside it were dead. MNP is now the path, loopback the fallback for a local
node with no live connection, and adding a root over MNP takes a typed path
since no web page can browse a remote disk.
Ejecting updated nobody's screen. transport.js resolves an admin ack against
the pending request and returns, which is right for every op whose caller
knows the value it chose; the root acks carry state only the node can compute,
so the operator who clicked Eject was the one client that never saw it happen.
And the ejected flag reached roster.db but was never read back, so a restart
undid it and the next scan read an empty mount point as an erased library.
Also: the member-upload endpoint answered 200 and did nothing (removed); the
wizard ignored the first root's RW switch; reload compared roots on name and
path, so editing writable in node.toml did nothing; the table had no path
column, which is the only thing separating two libraries sharing a basename;
apps_enabled normalisation differed between the two sides of a signed subject.
Tests: eject/plug, per-root upload refusal and the node.toml rewrite had no
coverage at all. test_member_upload_policy.py is replaced by
test_root_writable_policy.py — it tested a removed feature — and every
property worth keeping from it moved rather than being dropped.
Docs: draft-v6 structural decision 9 is annotated as superseded (the operator
can no longer have a directory only they may write to — a real capability
removed, flagged rather than hidden), the man page documents the root verb and
the RO/RW fields, and refactor-groups.md §7b records what the plan got wrong.
Suite: 41 failures before, 13 after — all 13 pre-existing on main.

Replace the upload boolean with per-root writable/removable/ejected flags.
Backend: new ops (update_root, eject_root, plug_root), MNP 1.1 protocol
messages, live RootSet updates so API always reflects current state, CLI
root subcommand (add/remove/set/list/eject/plug).
Frontend: SharedDirectoriesTable with optimistic toggle switches, eject/plug
in Files and Settings, upload gated on root.writable, ejected-root filtering
in all media apps, updated Create Group wizard, 10-locale i18n.

content
The real-time watchdog path lacked the duplicate-content guard that
reconciliation already had. When a file with identical content appeared
(e.g. browser download appending " (2)"), add_entry overwrote the
original's index entry — making it vanish from the file list despite
still being on disk. Now check get_entry before adding, matching the
reconciliation logic.

Files above 40 MB are no longer read in full. Instead, blake3 hashes
45 MB of samples (first 20 MB + last 20 MB + 5 MB at 50% offset).
Files at or below 40 MB are unchanged (full read, hash_version 1).
A new `hash_version` field on IndexEntry (default 1) travels on the
wire and through the cache so both versions coexist without breaking
existing nodes or clients.
The IndexCache auto-migrates its schema on open (ALTER TABLE), so no
manual step is required on upgrade. A standalone migration script is
available in QE/migration/ for operators who want to preview or force
a full re-hash.

scanning progress
Two real-world bugs found together while testing multi-root group
creation:
- CreateGroupWizard only sent the enabled-apps PUT when the operator had
*unchecked* something, assuming "every box left checked" already matched
the node's own default (Roster.DEFAULT_APPS = chat, files). It doesn't —
so leaving every app checked, the common case, silently left
Videos/Music/Photos disabled on the node. Now sent unconditionally.
- The wizard's "add extra roots" step never polled index-status, so once
step 3 (which only watches the first/upload root) finished, the
progress bar froze while the node kept scanning the remaining roots for
minutes, unwatched. Added waitForRootsIndexed (platform.js), mirroring
waitForGroupHosted's own race handling.
That fix exposed a deeper one: indexer.py's _scan_root() only flipped
`progress.scanning` on *after* walking the directory and stat()-ing every
file — both off-loop, but slow enough on a large root that a poller's
grace period (waitForRootsIndexed's 5s) could expire before ever
observing `scanning: true` (confirmed against production logs: a GEK-init
step fired 5.058s after a root started scanning, matching the grace
period almost exactly). The stat() pass was also a synchronous loop
directly on the asyncio event loop — blocking the whole daemon (WebRTC,
chat, admin UI) for as long as it took on a root with many files. Both
fixed: `scanning` now flips on before the walk starts, and stat()-ing is
now off-loop too (_size_files).

The "P.H. Theme" failure investigated earlier turned out to be a genuinely
corrupt 1256-byte source file with no audio stream at all, just an ID3
tag — a real, if rare, corruption pattern worth guarding against directly
rather than only handling gracefully at playback time. Scoped to audio
only, applied wherever a file actually gets hashed/typed (fresh scan and
the cache-miss rehash path alike) — a tiny file of any other type is still
indexed normally.

A real-library scan turned up 250 .wma and 23 .mpc files that the indexer
was silently classifying as "other" — genuinely lost from the Music app,
not a consolidation-rule artifact (checked separately: the grouping logic
itself drops nothing). Both are now indexed as audio and tagged properly:
- WMA has no mutagen "easy" wrapper, so the generic tag reader was reading
nothing from it at all. Reads the real ASF keys directly instead
(Title/Author/WM-AlbumTitle/WM-TrackNumber), confirmed against a real
sample file before writing the mapping.
- Musepack's format auto-detection is unreliable enough (misidentified a
real .mpc as MP3 in spot checks) that it now always opens by its own
class instead of guessing from content.
- Filters out another placeholder value found along the way: a French
ripping tool's auto-generated "Album inconnu (<timestamp>)".
Neither format decodes natively in a browser's <audio> element, so this
gets them correctly visible, tagged, and covered — not yet playable
in-browser. That would need server-side transcoding, deliberately left
out of this change.

Three bugs found live testing the Videos app against a real HEVC/EAC3 show,
plus a design change requested afterward:
- Streaming always did "-c:v copy", which faithfully reports a source's real
hev1 codec string but is unplayable in a browser with no HEVC decoder
(most Chrome/Linux builds). The node now transcodes to H264 whenever the
probed codec is browser-incompatible (media_probe.py's new
BROWSER_INCOMPATIBLE_VIDEO_CODECS), with a `transcode_incompatible_video`
node.toml opt-out for operators who know their viewers already decode it.
- Dropping a whole season into an already-watched folder gave no scanning
indicator and no progress bar: IndexProgress was only ever updated by the
two bulk scan paths, never by the real-time per-file watchdog path
(_schedule_update/_debounce/_update_entry). That path now accounts a
"burst" the same way, without double-counting a file rewritten mid-debounce.
- A stray literal "0" rendered in the video detail modal when there was no
TMDB match (`meta.confidence` is 0, and `0 && x` renders "0" in JSX/htm,
not nothing) — `confident` is now a real boolean.
- Whether TMDB is used at all moves from a node-wide setting to per-group
(OP_TMDB_ENABLED/tmdb_enabled/tmdb_enabled_ack, scoped like OP_VIDEO_ROOT):
an operator running a real media-library group alongside test/demo groups
on one node wants outbound TMDB traffic for the one that needs it, not all
of them. The custom API token and query language stay node-wide, one
shared credential/cache (tmdb_config/OP_TMDB_CONFIG, unchanged reasoning).
MNP_VERSION 0.6 -> 0.7, additive.

reconcile, and delta sync
Indexer performance work, in four parts:
- Persistent (path, size, mtime) -> hash cache (indexer/cache.py) so a node
restart no longer re-hashes every file — measured at 23 minutes for a
114 GB library on a slow disk before this, near-instant after. Hashing
is deliberately kept sequential (max_workers=1): it was never actually
concurrent despite the pool size, and two interleaved reads seek-thrash
a spinning disk instead of going faster.
- Byte-based scan progress (IndexProgress), surfaced via the loopback
index-status route, the handshake ack, and a periodic INDEX_PROGRESS
push to connected peers — drives a progress bar in the Create Group
wizard and "add a directory" in Settings, and an animated presence dot.
Guaranteed to settle back to idle via try/finally and a final push on
the scanning->false transition.
- The reconcile backstop's directory walks now run in the executor
instead of blocking the daemon's event loop; its interval defaults to
10 min (was 60s) with adaptive backoff to 2h when nothing changes,
reset on a real change or a peer connecting, and is now a per-group
operator setting (signed op + group Settings UI).
- INDEX_DELTA wired up (protocol support existed, nothing called it):
_on_index_change now sends additions/deletions instead of rebuilding
the full entries list, coalesced over a short window so a burst of
file events produces one push, and the hub swarm registration for
public groups only (re-)registers newly added hashes.
Also fixes several bugs found while testing the above against real
libraries (a 114 GB and a 100+ GB group on a USB HDD):
- /api/reload blocked until the reload — including a brand-new group's
full initial scan — finished, which the Electron bridge's fixed 30s
call timeout turned into a hard failure on any real library. The route
now fires the reload without waiting (ops.start_reload), matching
add_root/remove_root's existing pattern; the wizard's own step order
was fixed to wait for the group to actually appear hosted before the
steps that need it (extra roots, GEK), with retries for the residual
race between that and the daemon's own bookkeeping.
- transport.js's hand-rolled msgpack codec had no case for uint64/int64
(0xcf/0xd3) and crashed decoding any message containing one — hit by
IndexProgress.scanned_bytes/total_bytes for any group over ~4.3 GB.
Verified against real msgpack-encoded bytes from the Python side.
- chat_hist_resp, and this change's own index_progress and
set_scan_settings_ack pushes, were not routed by message type and
could be handed to an unrelated pending request by the transport's
"oldest pending" fallback, stalling it until its own 30s timeout and
corrupting whatever received the wrong reply in its place.

Node daemon no longer blocks startup on slow directory scans — initial
indexing runs in the background so the node reaches "running" immediately
after transports are up. Fixes the wizard failing to detect the node when
large USB/NAS roots take minutes to scan.
Also: wizard key-linking deadlock resolved (main.js links during poll),
invite form stays in DOM during reconnects (disabled instead of destroyed),
pairing code bridges to renderer, and firewall docs for LAN casting added.

Stage A — a group's content is a set of named roots
---------------------------------------------------
`shared_dir` becomes a list of {name, path, kind}. The name is the directory's
basename, derived once at add time and *stored*: recomputing it would
re-identify a whole library the day someone renames a folder on disk. Duplicate
names are refused case-insensitively and no root may contain another — both
compared with NFC folding, because most of these directories live on exFAT or
NTFS where `Films` and `films` are one directory.
Every index path carries its root name, in a one-root group as much as in a
five-root one. One path shape has to be got right once; two have to be kept
right for ever.
**A root that goes away freezes; it never empties.** Unmounting a volume makes
watchdog report every file under it as deleted, or presents an empty directory
to the next scan. Acting on either propagates deletions for a whole library to
every member, as though the owner had erased it. So a deletion is acted on only
once its root is confirmed readable, and availability is tracked per root — one
unplugged drive leaves the others serving. 12 tests, verified to fail against an
indexer without the check.
Events are not trusted to be complete either: ReadDirectoryChangesW drops them
under load and inotify on a FUSE mount misses changes made outside it. A
periodic reconciliation sweep is the only thing that recovers a missed event.
MNP 0.2 → 0.3 (additive). The hub needs no change: SwarmSource carries a content
hash, a node id and an endpoint — no paths, no filenames — and private groups
register nothing (H7).
Stage B — one implementation behind every front door
----------------------------------------------------
C1 and C6 were both "a second path into the node with its own weaker
handshake". Two implementations of `revoke` with two authorization checks is
that shape one size down. `meshbay_node/ops.py` holds each operation once,
takes the daemon state, and knows nothing about HTTP, argv or MNP. The loopback
API is one `_op(...)` line per endpoint; the MNP handlers call the same
functions. test_ops.py asserts the shape rather than trusting it.
Phase 14 is finished on top of it — `group list`, `gek init|rotate`, `reload`
(SIGHUP), `denylist show|clear`, `file list|rm`. **No operator action requires a
browser any more.** Plus `gek_rotate` and `member_unpin` as operator-signed MNP
operations: rotation is the half of revocation that revocation cannot do, since
the ex-member holds the current key, and the node generates the replacement
with its own CSPRNG — no key material crosses the wire, which is what the C5b
rule is actually about.
Two bugs found by running it rather than by testing it
------------------------------------------------------
GroupIndex is keyed by **content hash**, so the same bytes at two paths are one
entry — which is also why a scan reports ten files and indexes nine.
Reconciliation compared paths, so it decided the second path was a missed event
every 60 s, rewrote the entry and pushed an index update to every connected
peer. Seen in a live node's log.
`meshbay-node reload` crashed on first use with `subprocess` unimported: the
module compiles fine, which is the "syntax, not names" trap already recorded for
the SPA. test_cli_dispatch.py now walks every verb and refuses to let one be
added to the parser without an entry there.
Also corrected: protocol.py declared a second MNP_VERSION of "0.1" while the
wire carried "0.2" — harmless only because nothing imported it. And
_do_dir_create/_do_dir_delete referenced an undefined `filename` on their error
path.
740 tests pass; QE/deploy/e2e.py passes end to end against the live deployment.

Complete browser-based client: Preact SPA with login, group file browser,
encrypted download, video playback, group chat, i18n, and dark/light theme.
Browser connects P2P to nodes behind residential NAT via WebRTC DataChannel
(aiortc). Hub handles signaling only — all data flows E2E.
Performance: pipelined downloads (8-chunk sliding window), binary msgpack
wire format (no base64), redundant I/O elimination. Large file downloads
stream to disk via File System Access API (showSaveFilePicker).
Validated on SFR + Orange residential NATs, Chrome + Firefox, IPv4/IPv6.
132 tests passing. Deployed to meshbay.org + Orange node.

1. indexer.py: streaming blake3 (8MB chunks) instead of read_bytes().
Large files (initrd.img, ISOs, VM images) no longer load into RAM.
2. QE/demo-v1/run_node.py: call indexer.start() not initial_scan().
initial_scan() alone never starts the watchdog observer — files added
after startup were silently ignored. Added indexer.stop() on shutdown.
3. USERGUIDE.md §8: clarify symmetric vs asymmetric.
Ed25519/X25519 = asymmetric (key pairs). ChaCha20-Poly1305 and
AES-256-GCM = symmetric AEAD 256-bit (content encryption).
ChaCha20 is PRIMARY; AES-GCM is optional browser-compat variant only.
4. pyproject.toml: aioquic, websockets, aiosqlite, slowapi added to
proper package deps (were installed manually, now declared).
