<title>feat!: MNP 1.0 — seal index and handshake_ack under the group key</title>

<link rel='alternate' type='text/html' href='https://git.meshbay.org/meshbay.git/commit/?id=675beed6ff688733a9598f9d82d41578f48316be'/>
<id>urn:sha1:675beed6ff688733a9598f9d82d41578f48316be</id>
<content type='text'>
`index_sync`, `index_delta` and the `handshake_ack` config payload now travel
sealed under a GEK-derived subkey (`meshbay_common/groupbox.py`, mirrored by
`sealGroup`/`openGroup` in `crypto.js`). Only `type`, `v`, `group_id` and the
ack's `node_pk`/`proof`/`sig` stay in clear — a receiver must route and
authenticate before it would trust a decryption. Verify, then decrypt.

The ack line is integrity, not confidentiality: the signed handshake transcript
names no ack field, so `is_node_admin`, `enabled_apps`, `video_root` and the
rest were authenticated by the DTLS channel alone. The index line is defence in
depth against a repeat of C1/C6 — a peer served before the handshake completes
now gets ciphertext, not filenames. Nothing against an observer, the hub, or a
member; that is the whole claim. `index_progress` stays clear (D3, counters
only). Chat is out of scope.

Failure is fatal: a payload that does not open ends the session naming the
message type — never an empty index or an empty `enabled_apps`, both of which
are legitimate states.

Version negotiation ships here too (phase 15.6, brought forward): `v` + `v_min`
on `handshake` and `handshake_challenge`, refused with `version_too_old` /
`version_too_new` / `version_unreadable`. The flag day was already being paid
for; the next breaking change now costs a refusal message.

BREAKING CHANGE: breaks the WebRTC wire every deployed client speaks. Hub and
every node must deploy together; the SPA is served by the hub, so a browser
picks up the new client on reload. See MESHBAY_NODE_PROTOCOL.md §11.1a, §13.1.

<title>refactor!: one file_chunk and index_sync encoder for every transport</title>
<updated>2026-09-03T13:20:40Z</updated>

<published>2026-09-03T13:20:40Z</published>
<link rel='alternate' type='text/html' href='https://git.meshbay.org/meshbay.git/commit/?id=c1be7571973c3d0b671ed4db2da41266ae3099d8'/>
<id>urn:sha1:c1be7571973c3d0b671ed4db2da41266ae3099d8</id>
<content type='text'>
`file_chunk` and `index_sync` were each built twice, once per transport, and
the two copies did not agree. WebRTC sent binary, unsigned chunks carrying a
`file_id`; QUIC sent base64 fields, two BLAKE3 hashes, a per-chunk Ed25519
signature and no `file_id`. `index_sync` was plain entries on one transport
and a `GroupIndex.serialize()` envelope on the other. One message type, two
shapes, one consumer each, and nothing that failed when they drifted — finding
C6 one size down, in the two places the handshake unification did not reach.

Phase 9.15 moved WebRTC to the binary format and dropped the per-chunk
signature; the QUIC encoder was never brought along. It is dropped here rather
than reintroduced: the AES-GCM tag authenticates the ciphertext under a
GEK-derived key, and since C3 the node authenticates itself once in the
handshake instead of once per megabyte.

`meshbay_common.protocol` now owns the chunk codec (`chunk_ciphertext`,
`file_chunk_wire`, `file_chunk_plaintext`) and `meshbay_node/transport/wire.py`
the index builder, which also absorbs the delta the daemon used to hand-build.
`test_transport_wire_parity.py` fails if either server grows its own copy back.

`ChunkRequest`/`ChunkResponse` are deleted. `ChunkResponse` described the QUIC
half while reading like the contract for both, which is what made the fork hard
to see at all.

BREAKING CHANGE: MNP 0.15 changes the encoding of `file_chunk` and `index_sync`
on the QUIC transport. The WebRTC shapes are byte for byte unchanged and no
QUIC client ships, which is why this is a MINOR bump; a deployed QUIC peer
would have made it MAJOR.

Also fixes a test fixture that put a `Path` where the daemon puts a `RootSet`.
Nothing caught it: the old QUIC index handler never touched `roots`, and
`entry_abs_path` fell through `Path.resolve(strict=...)`, reading the virtual
path as a truthy flag and returning the right file by accident.

<title>feat: passphrase change and account recovery (auth-confirm)</title>
<updated>2026-08-31T23:03:43Z</updated>
<author>

<link rel='alternate' type='text/html' href='https://git.meshbay.org/meshbay.git/commit/?id=fe30860c58e0f1b1efd457ff5eb5146d1e592da0'/>
<id>urn:sha1:fe30860c58e0f1b1efd457ff5eb5146d1e592da0</id>
<content type='text'>
The passphrase derives two independent client-side values: auth_key (the
hub verifier) and bundle_key (AES-GCM key for the per-node identity
bundles, which live on nodes and never on the hub). Changing or
recovering a passphrase is therefore two operations — swap the hub
verifier, and re-wrap every reachable node's identity bundle.

Flow A — change a known passphrase (Profile page)
- POST /v1/users/password re-proves the current passphrase, swaps
  pw_hash/salt/version, revokes every refresh token and returns a fresh
  pair so the tab that made the change stays signed in.
- MeshBayTransport.rewrapAllNodes: for every group's online node, connect
  with the old key, read the identity off the handshake, store it back
  under the new key. Returns updated / unreachable / failed so the UI can
  point at the operator-unpin fallback for the gaps. Always-shown
  confirmation dialog listing reachable and unreachable groups.

Recovery key
- keyderive.js generateRecoveryKey (32 random bytes, grouped Base32) and
  deriveRecoveryKey (HKDF-SHA256, domain meshbay:recovery:v1:&lt;username&gt;).
- Every per-node identity gets a second copy wrapped under the recovery
  key: keypair_bundles.bundle_enc_recovery (node-only column, added in
  _SCHEMA_KEYPAIR and via a PRAGMA-guarded ALTER for existing DBs),
  carried on keypair_bundle_store / _resp. MNP 0.13 -&gt; 0.14, additive.
- session.recoveryKey is persisted in IndexedDB (slot rk) and lazy-loaded
  on connect, so a group joined in any later session still leaves a
  recovery copy.
- Shown once at registration; optionally folded into the verification
  e-mail as a pass-through the hub never stores or logs, with an opt-out.
- Profile -&gt; Recovery key re-loads R and backfills every reachable node
  via rewrapAllNodes in bundleKey mode (no passphrase re-entry).

Flow B — recover a lost passphrase (#/reset, linked from sign-in)
- POST /v1/users/password/reset-request {username, email}: both must be
  the pair on file, checked against the blind email_hash (never
  decrypted). A mismatch — wrong e-mail, unknown username, non-active
  account — takes the identical no-op path (no code, no mail, same 200),
  so it reveals nothing and cannot be used to spray reset mail from a
  username alone. 5/min, 1-hour single-use code.
- POST /v1/users/password/reset {username, code, new_auth_key}: same
  expiry / attempts / single-use checks as e-mail verification; revokes
  every session and deletes every registered device key so a stored one
  cannot sign back in past the reset.
- ResetPasswordPage: request code -&gt; code + optional recovery key + new
  passphrase -&gt; reset + sign-in -&gt; fan-out. connect() falls back to the
  recovery-wrapped copy when the passphrase key cannot open bundle_enc.
  Without a recovery key: sign-in is restored and each group needs the
  operator-unpin fallback.

Supporting fixes (found in live testing)
- member unpin now also deletes the keypair bundle; connect() mints a
  fresh identity when handed a bundle it cannot open (unless _rewrapOnly,
  set by rewrapAllNodes), so a rejoin completes instead of dead-ending
  before the invite-code prompt.
- A browser with no bundle key gets a passphrase prompt on the group page
  instead of a "go back to the browser you registered on" message.
- RegisterPage / LoginPage / ResetPasswordPage trim the username so every
  key derivation matches the hub's stored form.

Docs: docs/auth-confirm.md. Locale keys across all ten catalogues.
Tests: test_password_change, test_password_reset, test_recovery_email,
test_recovery_key, test_rewrap_fanout, test_bundle_store_recovery, plus
additions to test_admin_ops_mnp and test_webrtc_transport. Hub suite 492
passed; node suite 741 passed (the lone test_packaging_units failure is a
pre-existing RPM-spec flake, reproducible on main).

<title>feat: V13 — per-card "re-match this one file" (MNP 0.13)</title>

<content type='text'>
A one-click alternative to the full "Fix match" search-and-pick flow, and
reachable without SSH (`meshbay-node video rematch` clears a whole group).

- MNP 0.13: tmdb_rematch / tmdb_rematch_ack (additive — an older node
  logs "unknown type", the button just does nothing). OP_TMDB_REMATCH,
  signed like tmdb_override (media_cache is shared node-wide).
- media_cache.drop_tmdb_match(file_id): forgets the match AND the
  override marker — deliberately stronger than clear_file_tmdb, since the
  operator is explicitly asking for a fresh resolution.
- webrtc_server: _do_tmdb_rematch / _admin_exec_tmdb_rematch, dispatch +
  admin-response routing, broadcasts tmdb_rematch_ack.
- transport.js: rematchTmdbMatch(fileId, signFn); 'tmdb_rematch' in the
  admin-op allowlist; tmdb_rematch_ack handled like tmdb_override_ack.
- video-app.js: a "Re-match" button beside "Fix match" in the detail
  modal (isNodeAdmin), then bumpMediaMetaGeneration(). video.rematch_one
  key in all ten locales.

docs/mediacenter.md §10.1: V8–V13 marked done.

<link rel='alternate' type='text/html' href='https://git.meshbay.org/meshbay.git/commit/?id=c170b9cffd2b8fb4b7ef919ee62c28d2daaa8711'/>
<id>urn:sha1:c170b9cffd2b8fb4b7ef919ee62c28d2daaa8711</id>
<content type='text'>
Bump the three packages to 0.8.0 (released together) and realign
meshbay-common's __version__, which had drifted to 0.7.0 while the
pyproject stayed at 0.6.0. Dependency pins updated to meshbay-common&gt;=0.8.0.

Protocol versions are independent and unchanged: MNP 0.12, MHP 0.1. The
Electron client stays on its own 0.1.0 track (hub MIN_CLIENT_VERSION).

Since 0.6/0.7: public-groups admin switch with full server-side enforcement
and a group Revoke action; chat link previews (node-side URL unfurl, SSRF-
gated); chat composer focus + scroll-to-bottom on tab entry; whole-group
"Filter files" search.

<title>feat(chat): link previews for pasted URLs</title>
<updated>2026-08-28T01:43:19Z</updated>
<author>
<name>Christophe Besson</name>
<email>cbesson@gmail.com</email>

<published>2026-08-28T01:43:19Z</published>
<link rel='alternate' type='text/html' href='https://git.meshbay.org/meshbay.git/commit/?id=ce4e10c4b8bd9c66c375c3a5d5c18d8552655775'/>
<id>urn:sha1:ce4e10c4b8bd9c66c375c3a5d5c18d8552655775</id>
<content type='text'>
Paste an http(s) link in a group's chat and it unfurls into an OpenGraph
card — title, description, site name, and image — the way WhatsApp/Signal/
Slack do it.

The fetch is the node's, never the browser's or the hub's. The browser
cannot: a strict img-src/connect-src and CORS block it, and a direct fetch
would leak every reader's IP to the linked host on each render. The hub must
not touch group content (draft-v6 §2.5). The node already fetches third-party
metadata for the Videos and Music apps, over the same authorised path.

Flow mirrors media_meta_req: the client sends `link_preview_req {url}`, the
node replies `link_preview_resp` with the card fields (or `ok: false`), and
any OG image is stored under its blake3 in the existing media_cache thumb
store — the client then fetches it via the normal file_req path, exactly like
a poster. Nothing durable is added: the card text lives in a bounded in-memory
TTL cache on the node (draft-v6 §2.7 — enrichment on demand, the asking device
caches), and MNP goes 0.11 → 0.12 (additive: an older node logs "unknown type"
and the client shows the bare link).

Because the URL is chosen by a *member* and triggers an outbound request from
the operator's machine, `linkpreview.safe_url` is an SSRF gate: http(s) only,
no credentials, and every resolved address must be globally routable — no
loopback, private, link-local, multicast or reserved range, cloud-metadata
included. Redirects are followed by hand so each hop is re-checked. Residual,
documented in the module: DNS rebinding between the check and connect, closed
properly by pinning the checked IP — a follow-up.

Also fixes a long-standing chat annoyance the preview cards made worse:
opening the Chat tab landed a screen or two above the newest message because
the scroll-to-bottom ran before attachment thumbnails and (now) preview cards
had loaded and grown the content. A ResizeObserver keeps the view pinned to
the bottom through late content growth, and does nothing once the reader
scrolls up.

Tests: test_linkpreview.py (the SSRF gate and the OpenGraph parse, incl.
redirect re-validation and image downscaling) and test_link_preview_request.py
(reply shape, the media_cache image round-trip, the result cache).

<title>feat: add Photos group app</title>
<updated>2026-08-25T09:46:17Z</updated>
<author>
<name>Christophe Besson</name>
<email>cbesson@gmail.com</email>
</author>
<published>2026-08-25T09:46:17Z</published>
<link rel='alternate' type='text/html' href='https://git.meshbay.org/meshbay.git/commit/?id=2fcdd07d1e5d331ad02b723f1c45603a0989c264'/>
<id>urn:sha1:2fcdd07d1e5d331ad02b723f1c45603a0989c264</id>
<content type='text'>
A new group application (docs/apps.md's plug-in mechanism), following the
plan in docs/photos.md. Unlike Videos/Music: several photo roots per group
instead of one (photo_roots is a set, one signed op replaces it whole),
a single album-grid view with no third-party matching step, and per-photo
info read from the file's own EXIF at index time — no metadata service,
no credential, no outbound network call at all.

Protocol (meshbay-common, MNP 0.10 -&gt; 0.11, additive): `taken_at`/`camera`
on IndexEntry; `photo_roots`/`photo_roots_ack`; `OP_PHOTO_ROOTS`.

Node: roster.py stores photo_roots as a group_settings entry (JSON list,
same shape as enabled_apps); ops.py/webrtc_server.py validate and sign the
whole set in one op, same pattern as apps_enabled; a new PhotoEnricher
(indexer/enrich_photo.py) runs Pillow in its own small bounded pool,
separate from the video/audio pools, producing a resized thumbnail plus
the two EXIF fields — never GPS, checked by a grep-based regression test.

Client: photos-app.js — one album card per directory containing images,
a per-album photo grid, and a lightbox with next/previous (keyboard and
buttons), zoom in/out/fit/100% starting from the actual on-screen fit
percentage, and a "zip this album" button reusing files-app.js's own zip
mechanism (lifted into file-utils.js's downloadDirectory so both call the
same implementation). group-settings.js gets an add/remove multi-root
picker, distinct from Videos/Music's single-value one.

Bugs found and fixed before this ever shipped, worth keeping the story of:

- enrich_photo.py read width/height from the raw image *before* applying
  EXIF orientation correction, and read DateTimeOriginal off the plain
  0th-IFD Exif object — a real camera stores it in the Exif sub-IFD, which
  Pillow only exposes via get_ifd(Exif). A flat, hand-built EXIF dict
  round-trips through Pillow either way, which is exactly what would have
  hidden both bugs; the regression test builds EXIF with piexif instead,
  matching what real hardware produces.
- photos-app.js's album grouping stripped a trailing path segment from
  entry.path under the assumption it still carried a filename — it
  doesn't (files-app.js's own convention: e.path is already the
  containing directory), so every album collapsed one level into its
  parent. Found live against a real multi-folder library.
- transport.js's ADMIN_OP_TYPES allowlist (already the fix for an
  identical bug on video_root/apps_enabled, see 4783d81) was missing
  photo_roots: its admin_challenge matched no pending request and was
  silently dropped, so saving a photo root just timed out after 30s with
  no error.
- daemon.py pruned a thumbnail when its file left the index (root removed
  or reconfigured) but never forgot the content hash was "already
  attempted" — the same bytes reappearing under a renamed/relocated root
  (an operator's real workflow) were then permanently skipped, forever,
  with nothing to indicate why. Discarding the attempt alongside the
  cache entry on prune is what makes pruning actually reversible.
- packages/meshbay-client's app:// protocol handler served every file
  with no Cache-Control header, so Chromium was free to serve a stale
  cached copy indefinitely — none of several `npm run sync-ui` + reload
  cycles during development actually picked up the new code until the
  renderer's disk cache was cleared by hand. Now sends Cache-Control:
  no-store.
- the lightbox's zoomed image used flex centering (align-items/
  justify-content: center) combined with overflow: auto — a well-known
  trap where the browser centers overflowing content by shifting it, and
  the leading half of that overflow (here, the top of a zoomed photo)
  sits outside what the scrollport can actually reach. Reported live as
  "unusable". Fixed by switching to top/left alignment once zoomed.
