* feat(node): transfer leases, pools and a queue for downloads and uploadsChristophe Besson2026-09-081-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Step 2 of ~/next/improve-downloads.md. A download is invisible to the node: it is a series of independent `file_req` messages, with nothing saying one started or ended, so there is nothing to count and nothing to cap. The lease is that missing object. `meshbay_node/transfers.py` holds the decisions and has no asyncio and no transport in it, on purpose. The failure modes this has to survive — a slot the node never gets back, a client waiting on a grant the node has forgotten — are races through a DataChannel and unprovable there; here the clock is a parameter and every method returns what changed, so the caller does the I/O and the tests drive the worst case directly. What it decides: - two pools, downloads and uploads, separate from the stream pool: different resources with different costs, and merging them makes both caps meaningless; - per-member cap checked *before* the node-wide one, so a member at their own limit queues behind their own transfers rather than holding a slot a second member has none of. Per account across their devices, or the cap becomes a function of how many tabs somebody opens; - a queue that skips a member at their cap instead of waiting for them — granting strictly in arrival order lets one member's limit stall everyone; - `tr` drawn by the client and idempotent, which is what makes a reconnect safe; - bounded per member, because unbounded queues are how a node runs out of memory politely. Every way a slot comes back, with the session teardown as the one that matters (a closed tab, a quit browser and a dead network all arrive at `shutdown_tasks`, and none of them needs a timer): explicit close, session gone, a grant nobody took up in 30 s passed to the next in line, and a granted transfer silent for 120 s reclaimed with its peer told, so a widget can offer a resume rather than sit on a lie. `GET /api/transfers` is the operator's window: when somebody reports a transfer stuck at waiting, it is the only thing that says whether the node ever had them in a queue — a log cannot, when the symptom is that nothing is happening. It carries no filename and no path, which a test pins, because this is exactly where one would be tempting. Three things found while writing it, two of them mine: - the randomised property test rejected `in_use <= cap` at once, and it was right to: lowering a cap never interrupts a running transfer, so the count legitimately sits above the new value. The invariant is that a *new* grant never happens past the cap; - the sweeper was started with `self._spawn`, which ties a task to one session's set. It died with whichever peer opened the first transfer, and every other peer's abandoned lease then stopped being reclaimed — a node that fills up over days with nothing in the log. It belongs to the node now, with its strong reference on the transport context; - the pools are node-wide while `_peer_registry` is per group (finding H1), so a slot freed in one group can grant one in another and the peer to notify is not in the notifier's registry. Silently wrong in the first version. Nothing enforces a lease yet: `file_req` is untouched, no client asks, and the node grants everything. That is step 4's flag day, and this lands alone. 1148 node, 793 hub, 0 failed.

* feat(chat): Tier 2 — a member verifies another member's device itselfChristophe Besson2026-09-072-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chat messages have been signed by the sending device since MNP 2.0, but a reader had no way to know that the device belonged to the account the node named: the signature proved *a device*, and `sender_id` was still the node's word. This closes that for any account a client has already seen. **What was blocking it was not effort — the evidence was not being kept.** `_do_device_add` verified the countersignature that admits a second device and stored only `added_by_pk`: *which* key approved, never the proof. And `device_add_transcript` binds `nonce_node`, the approving connection's handshake nonce, so even a stored signature was unverifiable by anyone who had not been on that connection. `identities` gains `add_sig`, `add_nonce` and `add_ts`, added before the migration's early return — which fires on every roster widened since 2026-08-18, i.e. all of them, so putting them inside it would have meant they never arrived. `group_roster_req`/`resp` relays, sealed under a new groupbox purpose and answered to **any member of the group**, every live device of every active member with the evidence that admitted it. The node decides nothing: it hands over evidence and the client walks the chain from each account's root outwards (`_verifyRoster`). That is deliberate — the node is the party the property holds against, so it is not asked to assert trust. Two holes the tests caught while this was being built: - "no signature" was being treated as a trust root, so a node that writes the roster could put any key in an account's row and have it laundered straight into the verified set. A root is a device that names **no** countersigner. - pinning only the verified subset at first sight raised "key changed" on legitimate second devices whose countersignature predates this change. First sight pins everything the node says, because that is what trust-on-first-use means and an alarm that fires on normal events stops being read. The property, and it must not be rounded up: **once a client has seen an account, a node that later substitutes a key for it is detected. Nothing is gained at first sight**, where there is nothing to compare against — the same boundary `per-node-identity-v1.md` draws, unmoved. The cost, stated because it is real: the roster is member-visible, so every member learns how many devices the others hold and their public keys. It stays inside the group, the hub is not involved, and it is scoped per group. A member who cannot see the keys cannot check them. User-visible surface: one notice, "this account is using a key you have not seen before", in ten languages. Nothing else. 16 tests — 7 on the node (the evidence is stored, it verifies from the roster alone, a fabricated device carries none, another group's members are not disclosed), 9 running the shipped `_verifyRoster` under node against rosters built by the shipped Python: a chain of three in any order, a signature by the wrong key, one for another node, one for another account, and two fabricated devices signing each other admitting nothing. Tier 3 (operator-signed roster attestation) stays deferred, with nothing depending on it.

* docs(chat): correct the claim that two devices never share a keyChristophe Besson2026-09-071-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | `chatbox.py` said per-device subkey derivation means "two devices never share an AES key". That is false in the deployment that exists, and stating it hid the reason the design is actually safe. Two clients of one account on one node normally hold the **same** identity key: a second browser fetches the keypair bundle from the node and recovers the existing key rather than minting a new one, and so does a fresh Electron install. Device linking — a distinct key, countersigned — is the exception, not the rule, which is why nobody is ever asked to pin anything when they open a second browser. So two clients routinely share a device key and therefore its chat subkey. What makes that safe is the nonce, not the derivation: 96 random bits, never a counter. Two independent senders under one key collide only on the birthday bound, unreachable at chat volume; two independent senders advancing one *counter* collide immediately, which is precisely what C1 and §15.0b are about. The true property is "no mutable sending state at all" — the hazard removed rather than partitioned — and the design therefore degrades correctly into the deployment as it is, where a chain-based one would have failed silently on the day someone opened a second tab.

* Merge origin/main into the chat encryption workChristophe Besson2026-09-073-18/+203
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both sides landed a breaking MNP change and both called it 2.0, which is right: the sealed upload, the removal of `stream_seg` and mandatory chat encryption share one flag day. They are recorded as one version in `__init__.py` rather than as a race between two. The resolutions that were decisions rather than mechanics: * **`MNP_MIN_SUPPORTED` moves to "2.0".** The sealed upload alone was a *confined* break — a 1.x peer could still connect, browse, download, stream and chat, with only its uploads refused by `upload_not_sealed` — so the floor deliberately stayed at "1.0". Mandatory chat encryption ends that confinement: a 1.x peer can neither produce a sealed chat message nor read one, so it would connect, look fine, and be unable to say anything. Refusing it at the handshake is the honest form. The per-message `upload_not_sealed` path is untouched and still right if the floor is ever lowered. * **`sendChat` throws on an `error` reply**, from origin, applied to the sealed send. It matters more after this change, not less: the node now refuses a stale epoch, a malformed envelope and a device claim that is not the connection's own, so there are three new ways for a message to be rejected and none of them may look like a message that was sent. * **`req_id` supersedes the per-type routing** this branch added for `chat_keys_resp` and `device_hello_ack`. Both blocks are kept beside the existing `chat_hist_resp` one, for the same stated reason — a node too old to stamp — and their comments no longer claim to be the mechanism that closes the class. `req_id` is. * **`chat_send_probe.py` is rebuilt on origin's structure**, not beside it: two scenarios, a stub that stamps `req_id`, `music_meta_req` as the older pending request. The encrypted path is layered on — a real Ed25519 device key generated in the page, and a `chat_keys_resp` sealed by the shipped Python, because a payload the page built itself would prove only that the page agrees with the page. * **`test_reply_correlation.py` now sends a sealed message.** Its subject is which of the two messages leaving that handler carries the id; plaintext chat was only the fixture, and the node refuses one now. * `groupbox` keeps both new purposes (`upload`, `chat_keys`); `protocol.py` keeps origin's removal of `STREAM_SEGMENT` and this branch's correction of the "Double Ratchet message" comment on `CHAT_MESSAGE`, which was wrong when it was written and is wrong differently now. Full suite on the merged tree: 1993 passed, 11 failed — the same 11 that fail on a pristine checkout (2 Windows service tests, 1 apps-enabled policy, 7 transcode tests that pass in isolation, and the WebRTC invite test that hangs on its own).

| * feat(mnp)!: seal the upload under the group keyChristophe Besson2026-09-073-1/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Downloads have been encrypted under a GEK-derived key since the beginning: `file_chunk` and `stream_data` both go through `chunk_ciphertext`. Uploads never were. `file_upload` carried the filename and the raw bytes in plain msgpack, and `file_upload_ack` carried the name the node stored them under — so the same file was ciphertext leaving a node and plaintext arriving at one. There was no threat model behind that asymmetry. Both halves now travel sealed under a third groupbox purpose, HKDF(GEK, info="meshbay:upload:v1"). The filename, the destination folder and the bytes are all inside the seal; only `upload_id` and `chunk_index` stay in clear, because the node routes and orders on them before it can decrypt. This direction seals *towards* the node — it holds the GEK for its own group — and it opens the payload before it picks a destination or touches the disk. What that forced, and why none of it is optional: - `filename` was the correlation key on both sides. It cannot be: matching an ack to its request by name would hand back exactly what the seal hides. `upload_id` replaces it — client-drawn, opaque to the node, unique within a connection, never an authorization input. The property it guarded (one refusal fails one upload, not every upload in flight) is unchanged. - Refusals can no longer quote what they refused. `No directory named 'X'` becomes `No such directory in this group` plus the `code` that was already there; the client knows what it sent. - No plaintext fallback. A path that still accepts plaintext is not a sealed path, so an unsealed `file_upload` is refused with `upload_not_sealed`. Hardened while here, because what comes out of a seal is authenticated but not validated — a member can seal anything: `filename` and `data` have their types checked before any upload state is created, and `chunk_index`/`total_chunks`, which are outside the seal by necessity, can no longer raise where a refusal was meant. Tests. `test_upload_sealed.py` pins the node half: nothing identifying on the wire, tamper/wrong-key/wrong-group all refused with nothing written, and multi-chunk reassembly unchanged. `test_upload_seal_client.py` drives the shipped `uploadFile` over the shipped `crypto.js` under node and feeds its real frames to the real `_do_file_upload` — the file lands intact, and the ack the node actually produced comes back with the name it chose for a collision, which is the half a source-reading test cannot see. Both upload purposes join the JS/Python groupbox parity vectors. BREAKING CHANGE: MNP 2.0. `file_upload`/`file_upload_ack` change shape on the wire every deployed client speaks, which is MAJOR by the same rule 1.0 was — but the break is confined to uploads. `MNP_MIN_SUPPORTED` stays at "1.0", so a 1.x peer still connects, browses, downloads, streams and chats; only its uploads are refused, with a message saying which side is old. The client checks the node's version before sending a chunk, so neither side meets this as a timeout. This is the version negotiation shipped in 1.0 earning its keep: 1.0 cost a flag day, 2.0 costs a refusal code.

| * refactor(mnp)!: remove stream_seg, the last unencrypted content messageChristophe Besson2026-09-071-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `stream_seg` answered with an MPEG-TS segment as base64 with no encryption at all — the one message on the content plane that never went through a GEK-derived key. Live on both transports, answering any authenticated member. It predates `stream_data`, which does the same job properly (`chunk_ciphertext`, keyed per segment, AES-256-GCM) and has since Phase 12. Its only browser caller, `fetchStreamSegment`, was defined and never once invoked — a plaintext media endpoint with no client. Removed rather than repaired. Gone with it: `_extract_segment` and the ffmpeg semaphore in quic_server, the `fetch_stream_segment` QUIC client method, and `_b64decode` in transport.js, which had no other caller. The H6 regression test lived on this handler — it pinned `_do_stream_segment_async` to a coroutine so `subprocess.run` could not stall the event loop for thirty seconds per request. It is replaced by the property that outlives the handler: no transport carries media outside an AEAD, asserted on `stream_seg` and `data_b64` across all three transport modules. The half of H6 that survives — the live streaming path still spawns ffmpeg — keeps its own test. BREAKING CHANGE: `stream_seg` is no longer answered on either transport. No shipping client sends it. Recorded as part of MNP 2.0, whose other half — the sealed upload — carries the version bump.

| * fix(mnp): give a reply an id, so it stops being routed by luckChristophe Besson2026-09-071-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MNP carried no correlation id. A reply named its own type and nothing else, so a client with more than one request in flight worked out which one a message answered from the message itself — and for the replies that name nothing it could not. `_dispatch` fell through to matching by arrival order, which is a guess. `_sendAndWait` had the right value all along: it keys `_pending` by `this._seqId++` and never put it on the wire. The guess fails asymmetrically, which is why it hid. The victim is not the request that was answered wrongly — it is the unrelated one that now waits out its own 30s timeout for a reply already delivered elsewhere. Live on 2026-09-06: five `music_meta_req` sat pending for over 100 seconds behind a failing MusicBrainz, and a `device_list_result` was handed to one of them. The composer is disabled while a send is in flight, so a chat message whose reply went astray the same way left the Chat tab looking frozen for thirty seconds, then unfroze on its own. The `ack` half of this was fixed on 2026-08-30 by matching on request type. That closed the instance and left the class open: a refusal has no type to match on either, and `_dispatch_message`'s catch-all answers every unforeseen failure with `{"type": "error", "detail": "Request failed"}` — 238 of this module's 240 error sends name nothing at all. `req_id` now rides on the request and comes back on the reply. On the node it is published for the whole handler in a ContextVar and stamped by `_send`: a parameter would have meant threading an argument through all 240 send sites, and asyncio copies the context into a task, so a handler that `_spawn`s its real work still answers under the right id. It is never stamped on a broadcast — those answer nothing, and the owner check in `_send` is what keeps a chat broadcast or an index push from reaching another peer looking like a reply. On the client, `_dispatch` resolves on `req_id` first and the arrival-order fallback is gone the moment a node proves it stamps (`_correlates`, armed by the handshake's own reply). The fallback stays for an MNP 1.0 node, unchanged and no wider: there it is the only thing there is, and removing it would leave device_list_result, join_result and the handshake replies reaching nobody. Two things fall out. `sendChat` refuses an `error` reply like every other request in the file — it returned it as success, which did not matter while a refusal reached the wrong caller anyway and would now show a rejected message as sent. And `_group_ctx` uses `.get`: a reload pops a removed group while sessions connected to it are open, and every request they had left raised KeyError into that same catch-all. Sealed index messages are the one exception to the fast path. They cannot be handed over until they are opened, which is asynchronous while `_dispatch` is not — resolving on the id alone gave `fetchIndex` the envelope and skipped `onIndexSync` entirely. Caught by extending `index_seal_probe.mjs` to stamp a reply the way a current node does, after the hub suite passed over it: the probe built its own frames and had never seen one. Tests, all failing before and passing after: `test_chat_send.py` drives the real ChatPanel over the real transport for both shapes of reply with an older request pending (3 of its 6 are new, and the 3 for `ack` pass either way, so it discriminates); `test_reply_correlation.py` pins the node's half — the refusals that name nothing else, the broadcast that must not be stamped, and a late reply from a spawned task answering under its own id rather than the most recent request's. Full suite: 1897 passed, same 11 pre-existing failures as before. QUIC keeps its own dispatch and is not stamped. It is disabled by default and no browser request reaches it, but the asymmetry is real.

* | feat(chat): encrypt group chat under per-device epoch keys (MNP 2.0)Christophe Besson2026-09-078-22/+326
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chat messages are sealed with AES-256-GCM under a key derived per group, per epoch, per *device*, and signed over the ciphertext with the device key the node pinned. The node relays and archives; it cannot read a message. There is no switch. MNP goes to 2.0 and MNP_MIN_SUPPORTED moves with it, so a 1.x peer is refused at the handshake with `version_too_old` rather than admitted and then unable to speak. An opt-in flag was designed and rejected: every node is a test node, so it would have bought nothing and left a plaintext branch reachable — C6's lesson one feature later. A test reads the source and refuses any code that consults a `chat_encrypted` setting. Not Sender Keys, and `senderkeys.py` is now documented as unused. With distribution under the group key and a node that serves history to devices which were not present, the node must retain each chain's earliest key, and a chain key at iteration i yields every message key from i on by pure HKDF — forward secrecy is zero either way. What the ratchet was left buying was stateful client code with silent failure modes, three of them reproduced: any member could sign as any other, a second device dropped the first's chain, and the skipped-key cache grew without bound. The reasoning is in docs/chat-sender-keys.md, which is the specification and the decision record. Epochs, not rotation: the epoch key is wrapped under the group key at delivery and never stored under it, so `gek_rotate` is a re-wrap. A group-key-derived archive key would have made every message ever sent unreadable on the first `member unpin`, which is the documented step after removing a member. A new epoch opens on member revoke/unpin, device revoke and `gek_rotate`; old epochs are kept and still delivered, so history stays readable to everyone who could already read it, and nothing anywhere deletes one. Three prerequisites this needed, each a live defect on its own: * The peer registry was keyed by user_id, so one account's second device evicted the first and the broadcast skipped recipients by account — a person's phone never saw what they typed on their laptop. * The handshake authenticated an account, never a device. `device_hello` (additive, signed, refused unless the key is a live device of this account in the node's own roster) is what lets the node refuse a member claiming somebody else's key. * `_admin_exec_file_delete` authorized against the exact uploading key, so device linking had already broken deleting your own file from your other device. It now authorizes against any non-revoked device of `uploader_id`. Found by driving the real panel over the real transport, not by reading source: `chat_keys_resp` was routed by arrival order and handed to an unanswered `media_meta_req` — the original frozen-tab defect in a message type that did not exist when that probe was written. And `_asText` had been deleted with an unrelated helper beside it; its only caller sits inside a promise the panel catches, so every conversation rendered empty with nothing in the console. Existing node data is migrated by QE/migration/migrate_chat_encryption.py (not versioned, per the QE rule), run with the node stopped.

* feat(node): Phase 2 server side — one directory setting for every appChristophe Besson2026-09-062-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `video_root` (a string), `audio_root` (a string) and `photo_roots` (a list) said the same thing three ways: three roster accessors, three ops, three MNP messages, three admin-op subjects. They become `set_app_directories(app_key, paths)` and its single-directory wrapper, stored under `<app>_directories` and keyed by the app's registry name — so an application can be added without touching this layer, which is the whole claim of the plugin architecture. The three old names still work. Their MNP messages are handled, and the roster falls back to the old key when the new one is unset, so a node upgraded into this keeps working with no migration step — the plan called for a script, and a script nobody runs on the machine where it matters is worse than a fallback. Two things are new rather than moved: The paths are validated. The setters this replaces accepted anything, so a typo — or a path left behind when a root was removed — was stored happily and then matched no entry, leaving an app showing an empty tab with nothing to distinguish "misconfigured" from "no files yet". Deliberately not `RootSet.resolve()`: that also refuses a currently-unavailable root, and an operator must be able to point an app at a library on a drive they ejected. The legacy scalar is derived, never stored. `video_root` still rides on the handshake ack for MNP 1.0 clients; kept as a second stored value it would drift from the list within one run, which reads as "it works after a restart". Also here: chat's own two settings (a directory, which must be on a read-write root because it is a destination rather than a view, and a link-preview switch gating the unfurl path — checked before the cache, or turning it off would still serve every preview already fetched), the `app_directories`, `chat_directory` and `chat_link_preview` MNP messages, the plural `<app>_directories` on the handshake ack, and `music` as the app's one identifier where storage said `audio` and the registry said `music`. The Music enricher now resolves a boundary per configured directory rather than one for the group: with several, a single boundary is wrong for all but one of them, and for Music that is the difference between reading a folder as an artist and reading it as a release. Suite: 11 failures, all pre-existing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011pvMdvLBG92jyhvD5pD6us

* feat(node): indexing v2 — partial-read hashing for files above 40 MBChristophe Besson2026-09-061-0/+2
| | | | | | | | | | | | | | | | | 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. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

| | | | | | | | | | | | | | | A client whose clock is a little fast could not connect at all: the MNP handshake verified the hub-issued token with no leeway, so a token whose `iat` was a few seconds ahead of the node's clock failed with "the token is not yet valid (iat)". Seen against a freshly-resumed VM guest. `meshbay_common.handshake.JWT_LEEWAY_SECONDS = 60` is the shared value; applied to the handshake, the node's own hub-token decode, revocation-token verification, and the hub's access-token decode. 60s absorbs NTP-level skew without meaningfully widening the window on a stolen token (they already carry a jti and an exp).

* feat!: MNP 1.0 — seal index and handshake_ack under the group keyChristophe Besson2026-09-033-4/+216
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `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.

* refactor!: one file_chunk and index_sync encoder for every transportChristophe Besson2026-09-033-18/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `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.

* feat: passphrase change and account recovery (auth-confirm)Christophe Besson2026-09-012-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:<username>). - 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 -> 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 -> 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 -> code + optional recovery key + new passphrase -> reset + sign-in -> 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).

| | | | | | | | | | | | | | | | | | | | | | | | 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.

* feat(chat): link previews for pasted URLsChristophe Besson2026-08-282-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* feat: add Photos group appChristophe Besson2026-08-253-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 -> 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.

* feat(node): add audio_root, gate Music enrichment on it like video_rootChristophe Besson2026-08-243-1/+15
| | | | | | | | | | | | | | | | | | | | | | | musicbay.md's original call — Music needs no root, tag reads are cheap so just cover the whole shared tree — didn't hold up against a real messy library: everything under every shared folder got mixed together with no way to scope Music down to an actual music collection. This adds an audio_root setting, symmetric to video_root in every respect: signed operator op (audio_root/audio_root_ack, MNP bumped to 0.10), validated against a real directory in the group's own roots before a signature is even asked for, gates tag/cover enrichment exactly like video_root gates ffprobe/TMDB (nothing runs until it's set, only files under it once it is), and a set/change fires a one-off sweep of whatever the folder already contains. The old trigger — sweep everything the instant "music" joins enabled_apps — is gone along with the root-less design it belonged to; setting audio_root is now the trigger, mirroring set_video_root's enrich_video_root_fn exactly. Test coverage mirrors the video_root suite: policy (refuse before a signature round trip, accept/store correctly) and the enrichment gate itself (nothing without a root, only files under it, sweep on set).
* feat(music): transcode WMA/Musepack to AAC so they actually playChristophe Besson2026-08-242-1/+13
| | | | | | | | | | | | | | | | | | | | | Tagging and covers for these two formats landed already, but neither one decodes in any mainstream browser's <audio> element at all — a real library scan turned up 273 such files that would show up correctly in the Music app and then simply fail on click. This closes that gap: the node transcodes to AAC/M4A on request (a one-shot whole-file conversion, not live-piped like video's fMP4 segments — an audio file is small enough that streaming it buys nothing), caches the result under its own content hash the same way a TMDB poster or a MusicBrainz cover is cached, and serves it back through the ordinary file_req/chunk path. That path used to assume anything in the media cache was thumbnail-sized (single chunk, always); generalized it to slice a cached blob the same way a real file on disk gets sliced, since a transcoded track can be several MB. New MNP pair (`audio_transcode_req`/`_resp`, version bump to 0.9), shares its concurrency cap with video's transcode pool rather than getting its own — both are real ffmpeg processes on the same node. Every other audio format is untouched: this only fires for .wma/.mpc, the two extensions that need it.
* feat(node): Music app node-side — indexing, MusicBrainz enrichment, protocolChristophe Besson2026-08-243-1/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implements the node half of docs/musicbay.md against MNP 0.8: - IndexEntry gains artist/album/track_no (reuses duration/thumb_hash/ display_title, already generic). New musicbrainz_config/_enabled and music_meta_req/_resp message pairs, mirroring the TMDB shape. - title_parse.parse_track_filename: track-number-prefix + title parsing, fallback-only (embedded tags are the primary source, unlike Videos). - indexer.enrich_audio.AudioEnricher: mutagen-based tag/embedded-cover extraction through its own bounded pool (asyncio.to_thread, no subprocess — no ffmpeg-shaped deadlock risk). Gated on "music" in a group's enabled_apps rather than a video_root-style scoped folder. - musicbrainz.py: MusicBrainzClient — no API key (unlike TMDB), just a self-imposed ~1 req/s pace and a configurable, non-default User-Agent contact string; inert (no calls at all) when no contact is configured, never sends an unidentified client. - media_cache.py: file_mbid/mbid_meta tables alongside the existing TMDB ones, cover art reusing the thumbs table via a synthetic musicbrainz:{mbid} id, pruned on file deletion. - roster.py/ops.py/webrtc_server.py: musicbrainz_contact (node-wide) and musicbrainz_enabled (per-group, from the start) as signed operator settings, ALLOWED_APPS gains "music", _do_music_meta_request resolves and caches a release-level MusicBrainz match per (artist, album). - daemon.py: AudioEnricher/MusicBrainzClient wired alongside the video ones; a group's existing library is swept when "music" is newly enabled (no video_root equivalent — see musicbay.md §2.1). 41 new tests (musicbrainz.py against a mocked transport, admin-op policy for both new settings, media_cache round-trip/pruning, enrich_audio end-to-end against real ffmpeg-generated MP3s). Full suite (common + node + hub): 1116 passed, no regressions. Client-side (music-app.js, persistent player bar) not started yet.

* fix(node,hub): HEVC transcode fallback, live-add progress, per-group TMDB toggleChristophe Besson2026-08-243-10/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* feat(node,hub): season-specific overviews, manual TMDB match correction, and ↵Christophe Besson2026-08-243-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | wizard polish Two operator-facing fixes for a real 3-season show whose automatic TMDB match was wrong at the show level: per-season overview/air_date tabs in the detail modal (falling back to the show-level text when a season's own is empty), and a "Fix match…" search-and-correct affordance that re-resolves every file sharing the corrected show's display_title. New signed op OP_TMDB_OVERRIDE and two read-only pairs (season_meta_req/resp, tmdb_search_req/resp), MNP_VERSION 0.5 -> 0.6. Also: the create-group wizard gets a spinning indexing indicator and an app-selection step, group settings default the TMDB language to the operator's own locale (never as a global default), and a file renamed mid-session now re-triggers title parsing instead of being silently skipped by the enrichment dedup guard. Fixes two bugs found during this work: the search overlay's z-index lost to the base video-overlay class and rendered invisibly, and season_meta's own empty overview didn't fall back to the show-level one.

* feat(node,hub): add Videos group app (poster grid, flat list, TMDB metadata)Christophe Besson2026-08-243-1/+52
| | | | | | | | | | | | | | | | | | | | | Implements docs/mediacenter.md: a "Videos" group application built on the existing files index rather than a separate catalogue. On the node side, new indexer enrichment (technical probe, filename/season parsing, thumbnail generation) runs per-file once an operator has chosen a video_root for the group, plus a TMDB client for on-demand poster/metadata lookups (never client-side, thumbnails delivered over the existing chunk path). On the hub side, a new video-app.js renders a lazily-mounted poster grid or a thumbnail-only flat list, with TMDB entirely optional per group. Along the way: the global apps registry now drives Settings' default-tab picker instead of a hardcoded list, and the video_root is configured from group Settings (like uploads) rather than from Files, with the node refusing to run any TMDB/thumbnail work until one is set. Fixes several bugs found via live testing against a real library, notably a race between two effects writing the same "image ready" state that could leave a poster grid spinning forever on a same-tab revisit — see mediacenter.md §5.4 for the full account of each one.
* feat(node): persistent index cache, visible scan progress, adaptive ↵Christophe Besson2026-08-232-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* chore: release 0.6.00.6Christophe Besson2026-08-231-2/+6
| | | | | | | | | | | | | The group UI's applications split, and the two missing-import bugs it surfaced and fixed along the way. MNP goes to 0.4: apps_enabled/apps_enabled_ack, and enabled_apps on the handshake ack, for the group-applications registry. Additive — a node that predates it is never sent the op, and a client that predates it never looks for the field.

* feat(hub): split the group UI into a pluggable "applications" architectureChristophe Besson2026-08-232-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GroupPage's 6620-line app.js carried Chat and Files wedged in directly, with no way to add another group-level app without touching the shell itself. It is now app.js (routing, non-group pages) plus nine focused files — apps.js (the registry), chat-app.js, files-app.js, video-player.js, group-page.js (the shell), group-settings.js, hub-client.js, icon.js and file-utils.js — with docs/apps.md as the checklist for adding one (Videos/Music/Photos are sketched there, not built). Node side gained the matching enablement mechanism, mirroring member_upload exactly: a roster setting, a signed apps_enabled op enforced by _has_admin_authority, exposed in the handshake ack. Operators toggle applications per group from Settings, which also gained a small reorder: Invite, Pairing, Applications, Shared directories, Uploads, danger zone, Your devices, Members. Two bugs surfaced during the split, both missing an import across the new file boundary and invisible to node --check or a module-load probe since they only throw when the code path actually runs: - group-page.js called onRefreshAuth on a stale-token handshake rejection, but app.js never imported refreshAccessToken from hub-client.js — so a brand new member (including a group's own creator) hit "Not a member of this group" and the retry silently failed, throwing before it could refresh the token. - chat-app.js called getLocale() for message timestamps without importing it from i18n.js. Opening Chat on a group with real messages threw mid- render; uncaught, that appears to wedge Preact's render scheduler, so every button on the page stopped responding until reload. Caught the second class of bug with a proper no-undef audit across all split files (a temporarily installed ESLint 9, since the system one is too old to parse this codebase's syntax) rather than trusting grep. 827 tests pass; 6 new ones cover the apps_enabled policy.

* feat(node): full Node admin panel — CLI parity, hot-reload, group lifecycleChristophe Besson2026-08-202-0/+22
| | | | | | | | | | | | | | | | | | | | Node admin panel (NodePage) now covers every CLI operation over MNP: group attach/detach, roster, member unpin, GEK rotate, denylist, reload. Daemon hot-loads new groups and tears down removed ones on config reload instead of requiring a full restart. Group attach/detach via MNP or local API triggers an automatic reload so the group is live immediately. Fixed GroupPage hang on first visit to a newly created group: the JWT issued at login didn't include the new group, the node rejected with not_a_member, and the token-refresh path returned without re-triggering the connect effect (Boolean(token) didn't change). Now bumps retryKey after a successful refresh so the effect re-runs with the fresh token. NodePage marks groups hosted by the node but absent from the hub with a "not on hub" badge so stale groups are visible and easy to remove. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat(node): the operator can close uploading to everyone but themselvesChristophe Besson2026-08-182-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A group where every member may add files stays the default. Some groups want a library the operator curates, and until now the only way to get one was to designate no upload root at all — which refuses the operator too. **The node enforces it; the interface merely stops offering it.** The Upload button in the Files toolbar and the paperclip in the chat composer both disappear, which is a courtesy to the people who are not trying. The control is `_do_file_upload` refusing with `member_upload_off`, so a member on an old tab, or one speaking MNP directly, gets the same answer. There is a test for each, and the enforcement test is in the node package rather than beside the UI one so nobody reads the hidden button as the mechanism. **Changing it is a signed operator instruction** — `OP_MEMBER_UPLOAD`, on the same path as removing a member. An unsigned one would let any member turn it back on and make the setting a suggestion. The transcript's subject is `on` or `off`: what the operator is shown before signing has to name the outcome, not the operation. **It lives on the node**, in a new `group_settings` table in `roster.db`. Not the hub, which has no business deciding who may write to someone else's disk. Not `node.toml` either: that file is hand-written and full of comments recording decisions, `ops.py` appends to it rather than round-tripping it through a writer, and a setting toggled from a panel must not rewrite the operator's file or need a restart. The value is cached in the group context because the upload path is synchronous, and the signed operation updates both — storing it without applying it would make the panel say one thing while the node did another. **Absent means allowed**, at every layer: no row in the table, no key in the context, no field in `handshake_ack`. An older node and an older client both behave exactly as before, and upgrading never silently closes a group. Each of those three has its own test, because they fail independently. The operator is always exempt — otherwise turning it off locks them out of their own node with a config file and a restart as the only way back. `is_node_admin` was being computed in two places by then and is now one function, since two copies of "is this the operator" is how the ack and the gate come to disagree. A change reaches everyone already connected via `member_upload_ack`, so the button goes without a reconnection. That message is both a broadcast and the reply to the request that caused it, which is why the client does not return early on it. Docs updated for a cold start: draft-v6 §2.1b and change 9, a new "Where Phase 13 stands" section in CLAUDE.md recording what is built, deployed and still missing, the module map row, and desktop-client-v1 §10b on the Settings tab and where group settings live. 883 tests pass.

* feat: device linking, and signing in to the hub with a device keyChristophe Besson2026-08-182-0/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stage C. Identity keys are per node, so a browser and a desktop client are two keys on one account there — and the node refused the second where it accepted the first. Without this, an account created natively could never be opened in a browser without an operator code per node, and "a native client must not prevent web use" would have been dead on arrival. Device linking (node) --------------------- `identities` is keyed by `(user_id, pk_ed25519)` instead of `user_id` alone. The old shape did `INSERT OR REPLACE`, so a second device overwrote the first silently; SQLite cannot change a primary key in place, so the table is rebuilt. Existing pins are carried over — verified against a live roster with 10 of them, nobody re-pairs. A new device files a request bound by `sha256(code ‖ its own keys)`, and a key the node **already pinned** countersigns it. The hub cannot: it has stored no user keys since 2026-08-14, which is what makes this safe to do without an operator in the loop. **The code never reaches the node.** It lists this account's pending requests with their stored hashes; the approver recomputes and keeps the match. A node offering fabricated keys would have to produce a hash over a code it has never seen. Nothing rests on a human comparing digits — that ritual was dropped in 12.1 as "correct, unusable as the default" and must not return by the back door. The design document had the approver look a request up *by* its hash, which is circular: computing it needs the keys being asked about. Corrected in both. Revocation marks rather than deletes, because a deleted row is a key the node would happily pin again — which is the laptop somebody just reported lost. Your last device cannot be revoked: coming back would need an operator's code. Hub — the only change in the whole plan --------------------------------------- `POST /v1/users/auth` signs in with a device Ed25519 key, on the same pattern as `/v1/nodes/auth`, plus `/v1/users/devices` to register, list and retire. New `user_devices` table with an Alembic migration, because `create_all()` is not one. This is **not** the key directory that was H3, and the tests say so: nothing reads it but the hub, no group key is ever wrapped for one, and it is a different key from the per-node identities. What it does cost is metadata — the hub now knows how many devices an account has and when each last signed in. Also `client.minimum` / `client.recommended` in `GET /v1/hub/version`: an installed client meets a newer hub the day the interface ships in a package, and that is cheap now and awkward to retrofit. Browser ------- The `key_changed` refusal becomes `unknown_device` and offers a linking code instead of telling someone to find their operator. The Members panel lists this account's devices here, approves one by code, and retires one. 773 tests pass. `e2e.py` gained a step that links a device end to end against the live deployment — file, list, recompute, countersign, then open the group with the new keys and no code — and it also gained `recv_type`, because a step that assumes the next message is its own answer reads an ack left by the step before.

* feat(node): several named roots per group, and one implementation per operationChristophe Besson2026-08-184-3/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* feat(common): MNP 0.2 — liveness, and chat history read the way it is writtenChristophe Besson2026-08-162-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | `get_messages` pages forward from the oldest message. That is the right shape for "what happened since I last looked" and the wrong one for opening a conversation, and the browser asked it for `since=0, limit=200` — so a group with more than two hundred messages showed its first two hundred and the exchange anyone came for was unreachable. Demonstrated on 300 messages: the newest was simply absent from the answer. `get_recent` and `get_before` page backwards, cursored on the row id rather than the timestamp. Nothing makes a `time.time()` float unique, and a cursor on a value two rows can share eventually skips a message or repeats it. PING/PONG covers liveness on an already-open channel: a DataChannel whose peer vanished without closing still reads as connected, and nothing noticed until a real request hung. It is not a discovery mechanism — opening a connection to ping costs a full ICE/DTLS handshake, measured at 0.6-7 s across two ISPs — so presence in the group list comes from the hub's registry instead. Both additions are backward compatible: an 0.1 peer sends no `before` and is answered with the newest page, which is what it wanted. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* chore: release 0.4.00.4Christophe Besson2026-08-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The web client speaks ten languages instead of one: French, Spanish, Brazilian Portuguese, Simplified Chinese, Japanese, German, Italian, Dutch and Polish, all formal, with `hub`, `node` and `GEK` deliberately left in English so the interface still matches the CLI and the docs. Catalogues are fetched per language rather than shipped together, plural forms go through Intl.PluralRules because Polish needs four of them, and locale matching keeps the region so pt-BR and zh-CN resolve to the files written for them. Splitting one module into a loader and ten catalogues gave the SPA a version dependency it did not have before, and the hub was serving static assets with no explicit freshness at all. A browser that cached half a deploy either rendered every string as its own key or, in the other direction, failed to link the module graph and showed nothing. Static responses now carry no-cache, which costs one conditional request and answers 304 with no body. The node and common packages carry no functional change; they move with the version because the three are released together. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* chore: release 0.3.00.3Christophe Besson2026-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Twenty-one commits since 0.2, and enough of them change what the thing does that moving the old tag would have been the wrong description. Node: video streaming paced by the client rather than pushed at it, and a stream that ends when the viewer closes instead of holding a transcode slot for two minutes. An operator can remove an empty directory and revoke a member over MNP. `meshbay-node group add` attaches another hub group without hand-editing node.toml. The node.toml operator key is gone; the roster is the only source of authority. Hub and web client: transfers outlive the page that started them, with a widget that shows the rate and can cancel them; downloads stream to disk in every browser, through the File System Access API where it exists and a service worker where it does not; a folder can be taken as a zip built in the browser. A group owner can remove a member and edit the description. Nodes are recorded at the address their signed announcement arrived from, not the one STUN told them about. Deleted accounts stop being counted while the connection log keeps their name. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix: stop a stream on close, count only real users, record where a node isChristophe Besson2026-08-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | **Closing the viewer left the node working.** Nothing told it to stop: the player dropped its handlers, which only made the browser deaf. ffmpeg kept running and held one of the node's two transcode slots until the credit timeout expired two minutes later — which is why the next video answered "server busy". `stream_stop` ends it at once, and the viewer also drops its queue, ends the MediaSource and revokes the object URL on the way out, any of which could be holding megabytes of decrypted video. While there: `file_chunk` replies were matched to their requests by arrival order, which was true by luck rather than by construction. The reply now names the file it belongs to and is matched on that and the chunk index; a chunk nobody is waiting for is dropped instead of being handed to whatever request happens to be oldest. **The administration panel counted its own history.** A deleted account is tombstoned so the connection log stays readable, and every count and list treated that row as a user — including a group's member count, and the member list of the group itself. They do not any more. **Where a node is.** `endpoint_hint` is what a node believes its address to be, learned from a STUN server and sent to us: useful for reaching it, and a claim. The announcement that carries it is signed with the node key over a fresh timestamp, so the address that request *arrives from* is the address of whoever holds that key — that is now recorded on the node row and shown in a Nodes tab, next to the hint, with the difference spelled out. Clients get the same treatment: `webrtc_offer` is logged with the address the hub saw when a browser starts a peer connection. Verified against the live deployment: the node's row reads 90.112.206.172 after a restart, and in e2e a stopped stream goes quiet in one message and the next one starts immediately instead of being refused.

* feat(groups): remove a member, and keep gigabytes out of the tabChristophe Besson2026-08-152-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | **Removing a member.** The owner can do it from the Members tab, and it is two halves in the order that fails safe: the node stops serving the group key first (an operator-signed request, so a paired browser only), then the hub drops the membership row. The other order would leave someone able to reach a node that still serves them. It is a membership, not an account. The user row is never written: their other groups, their files and their pinned identity survive, because one group's owner must not be able to erase someone from the hub. It is also per group — a node hosting two loses them from one — and it does not take back the key they already unwrapped, which is what rotating the GEK is for. The confirmation and the panel both say so. **Downloads and streaming through the disk, in both browsers.** The audit this started as found two ways to put gigabytes in a tab. Firefox and Safari have no File System Access API, so every download there was collected in memory. A service worker fixes it: the page keeps the writable half of a transferred stream, the worker answers a made-up URL with the readable half and a Content-Disposition header, and the browser writes it to disk as it arrives, with real backpressure. The worker caches nothing and falls through on every request that is not one of these downloads. A zip announces no Content-Length, since the archive is larger than the files in it and a length we miss truncates the file. Video was worse and affected both browsers. The node pushed ffmpeg's whole output as fast as it was produced while the player consumed a segment at a time, so the queue held the film — and appending all of it hit the SourceBuffer's cap, where the handler logged the error and dropped the segment, leaving a hole in the middle of the film with nothing to show for it. Streaming is credit-based now, 24 segments of 256 KB in flight, verified against the live node: three credits, three segments, then silence until more are granted. The player evicts what is more than a minute behind the playhead and retries a refused segment rather than dropping it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* feat(files): download a folder as a zip, and remove an empty oneChristophe Besson2026-08-152-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two things a Files panel needs and did not have. **Removing a directory** is privileged, where creating one is not: it acts on a name other members are using, on the operator's disk. It is refused unless the directory is empty, and that rule is the safety property — whatever the browser sends, this cannot destroy content. The check runs twice, once before the challenge and once after the signature comes back, because a file can land during the round trip. A file also accepts its uploader's key; a directory has no uploader, so only the operator's key will do. **Downloading a folder** produces a zip built in the browser, written straight to disk as the chunks arrive. An archive of a group folder is routinely tens of gigabytes, so nothing is held: peak memory is one chunk plus a small record per file. The node is not involved at all — it serves the same encrypted chunks as any other download, holds no temporary files, and cannot be asked to compress anything. zipstream.js is store-only. Group content is video and images, already compressed, so deflate would spend CPU on every byte to save nothing, in the thread that is also decrypting. Sizes and CRCs go in a data descriptor after each file because a stream cannot seek back to patch a header, and zip64 kicks in per entry past 4 GiB and for the archive itself. Because none of that can be checked from the Python side of the house, test_zipstream.py runs the real module under Node and reads what it produces with zipfile — CRCs, UTF-8 names, zip64 records and all. The archives also pass `unzip -t`. Firefox and Safari have no File System Access API, so there is nowhere to stream to: the fallback builds the archive in memory and says so, with the size, before starting rather than after failing. One mistake worth recording: the first version of deleteDirectory passed the node's own answer as the value to check the challenge against, which turns the comparison into a tautology. It checks the path we asked for. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* feat(files): upload into the current directory, and create foldersChristophe Besson2026-08-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The per-user quarantine is gone. `.uploads/{user_id}/` was the fix for C5a, and it worked, but it made the shared directory something nobody could organise: every file landed under a uuid nobody recognises. Files now go where the member is looking, most often the root. What the quarantine actually bought is kept, and is now what the tests assert rather than the location: - an existing file is never replaced. That was the real defect — overwriting a file also made the attacker its recorded uploader, and therefore able to delete it through the uploader path - the name allowlist is unchanged - the destination is confined under the shared root That last one is new surface: the directory arrives from the client. safe_subdir() is the single place that decides, with two independent guards — every segment against the name allowlist, and the resolved result under the root — because one of them will eventually be refactored by someone who does not know why it is there. Ten traversal cases are covered, and they fail if both guards go. Also adds `dir_create` (any member may organise a shared directory; audited like anything that writes to the operator's disk) and makes the node report its real directory list in index_sync — folders were inferred from file paths, so a new empty one, or one that had been emptied, simply did not exist as far as the UI was concerned. Two C5a tests changed their assertions deliberately, as C5b's did before: they encoded the quarantine path, which is the thing being removed. The property they existed for is asserted more directly than before. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One keypair was copied to every node its owner joined, so cracking the bundle on any single node yielded the identity used on all of them: their content on other operators' machines, and the ability to sign as them anywhere. That lateral reach was the part of C4 worth attacking. Each node now gets its own keypair, generated the first time its owner joins it and left with that node alone. An operator who cracks what sits on their own disk holds a key that is a stranger to every other node — and on their own node, one that unlocks nothing they did not already hold: they serve the content, the index and every byte of it by design. Nothing changes for the user. A first contact with a node already needed that operator's code, and the key is created in the same step; a second browser still recovers it from the node with the passphrase alone. Two operators can also no longer tell they host the same person by comparing keys. BREAKING, and deliberately without a compatibility path — the deployment is wiped for the next demo: - users.pk_ed25519 / pk_x25519 dropped (migration a7c31f9e40b2) - registration no longer sends or stores a key - PUT /v1/users/me/keys and regenerateKeys() gone; rotation is now `member unpin` plus a fresh code, decided on the machine that pinned it - /pubkeys returns an account id and a node's linking key. It was the directory H3 read, and nothing wraps for it any more - the pk_user JWT claim is gone That last one closed a live defect the inventory turned up: the node recorded pk_user as the uploader's identity and authorized deletion against it, so a hub issuing a token naming its own key could delete anyone's uploads on any node. Attribution now uses the key the node itself pinned. A simplification falls out. Registration generates nothing, so a scripted signup is a real account: `demo.py bootstrap` takes a wiped hub and node to a working demo with no browser, which was impossible while keys were born in one. Also fixes, found by running it on a wiped deployment: the key handed back on a join now belongs to the group the connection is for, not the group named in the invitation — an operator pairs node-wide but redeems the code while opening a group, and expects to read it. Tests: 343, including the two that state the property — a key pinned by one node is refused at another, and someone else's code does not admit it. Verified end to end against a wiped hub and node: bootstrap, pair, invite, join, download, stream, second browser, revoke.

* feat(client): make the key backup a choice, and raise the passphrase floorChristophe Besson2026-08-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two things the multi-browser story made obvious. **The backup is now opt-out.** Keys are kept, encrypted with the passphrase, on every node whose group you join — that is what lets a second browser recover them, and it is finding C4: a PBKDF2-protected blob on other people's disks, attackable offline at the speed of PBKDF2, which is memory-light and therefore cheap on a GPU. Until now everybody paid that cost, including people who will only ever use one browser and get nothing back for it. Settings → "Use this account on other devices". Turning it off does not merely stop future uploads: the next connection to each node withdraws what that node already holds (new keypair_bundle_delete, which only ever deletes the caller's own, taken from the authenticated session and never from the message). The warning says plainly what it costs — clearing the browser then loses everything encrypted for that account, with no recovery, which is the point of choosing it. Default is on. Silent, unrecoverable key loss is worse for an ordinary user than an exposure the roadmap already tracks, but that is a judgement call and it is now visible and reversible instead of implicit. **Passphrase floor 8 → 12 characters, plus a strength estimate** shown while typing, with a refusal below ~60 bits. This number matters more here than in most applications: it is what stands between a node operator and your identity keys. It has to live in the client — with the password split (T1) the hub never sees a password and cannot enforce anything about one — so the UI says why it is asking, rather than nagging. The estimator is deliberately conservative and dependency-free: character classes and length, penalised for repetition and for the handful of patterns everyone tries. Verified against the live deployment: withdrawing the backup leaves a second browser unable to recover anything, which is exactly what it promises, and re-enabling restores it. Tests: 338.

* fix(client): refresh the token when the node says "not a member"Christophe Besson2026-08-141-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | A member added to a group after they signed in was refused by the node, told "Not a member of this group", and had no way forward but to log out and back in. The hub bakes `groups` into the access token at login and never pushes updates, so the token said they were in nothing while the database said otherwise. This lands on every newly invited member, at their first action, and the message tells them the opposite of the truth — toto2 was a member of newdemo on the hub and read that they were not. The refusal now carries a code the client can act on (`not_a_member`) rather than prose it would have to string-match, and the SPA refreshes the access token once and retries. Refreshing re-reads membership from the database, so the retry succeeds. Once per mount: if a fresh token still says not a member, that is the truth and it gets shown. The SPA had stored a refresh token since Phase 8 and never used it. It does now. Found in a browser, doing the ordinary thing — the automated run never sees it, because e2e.py logs in after being added to the group. Tests: 233 node+common, including a handshake test that the refusal carries the code, and the full e2e run against the live deployment. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* feat(node)!: the node wraps the group key — closes H3 and M3Christophe Besson2026-08-143-3/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The invite flow fetched the invitee's pk_x25519 from the hub and wrapped the GEK for whatever came back (app.js:1466, and gek-init did the same server-side). The hub is the key directory, so a hub answering with its own key was handed the group key by an honest member following the protocol exactly. No forgery, no injection, nothing for the client to notice. That was H3. The fix is not safety numbers. Nobody reads the directory any more: - the node holds the GEK and wraps it itself, on every connection, for the X25519 key the joiner signed with their Ed25519 identity in one transcript (meshbay:join:v1), so the identity key vouches for the encryption key; - identities are bound to accounts by a one-time code the hub never sees — 40 bits, single use, one account, bounded per connection AND node-wide; - the node's own roster decides who may receive the key. Hub membership lets someone reach a node; it no longer gets them anything. A hub that invents an account and mints it a token is answered not_authorized_for_group. Safety numbers would have made substitution detectable by a human who checks, at the moment there is nothing to check against — first contact. Removing the lookup makes it impossible, and costs the user one code to pass along. M3 falls out of the same work. The daemon auto-pinned its own keystore key as admin_pk_ed25519 while the browser signs with the user identity key, so every privileged operation failed closed with a signature error that looked like a bug somewhere else; the demo only worked because a deploy script overwrote the value. Authority now comes from the roster, established locally by `operator pair`. Asking the hub for the operator's key — the obvious-looking fix — would have let the hub install itself as node administrator. BREAKING: gek_bundle_store is deleted, not gated. No member hands the node key material at all, so C5b becomes structural rather than an authorization to check. Existing stored bundles are still served, so current deployments keep working. Also: - join_policy (invite|open) is read from node.toml, never from the hub — a hub able to declare a group open would be handed its key. Unknown group ⇒ invite. - admin signatures are verified against the roster on every check, so unpinning takes effect without a restart. admin_pk_ed25519 stays readable as legacy. - two C5b tests were rewritten, deliberately: they asserted that gek_bundle_store demanded an operator signature, and the message is gone. They now assert the stronger property. The file says not to fix these tests, so this is the record of why they changed. - a slice-1 bug found while writing slice 2: connect() never passed skEdB64, so pairing would have failed at runtime with no test able to catch it. Tests: 152 node+common here, including an end-to-end DataChannel run where a member who has never held the group key redeems a code in the pre-proof window and receives the key wrapped for a key only they can open.
