* fix(packaging): the hub unit can start, and nothing carries the migration pathChristophe Besson2026-09-121-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `ExecStartPre` ran `alembic -c /opt/meshbay-hub/migrations/alembic.ini upgrade head`. The build does stage that file, so the path existed and the contents were wrong: `alembic.ini` resolves `script_location` with `%(here)s`, so the copy pointed at `/opt/meshbay-hub/migrations/src/meshbay_hub/db/migrations` — which nothing installs, because the migrations ship inside `meshbay_hub`, in the shared venv. `ExecStartPre` failing stops the unit. A hub installed from the RPM or the DEB could not start at all, and nothing noticed because the one live deployment was assembled by hand — the same shape as the node unit that carried `User=` into the user unit directory. The same `%(here)s` trap was already found once on the server, where a stray `alembic.ini` resolved to a month-old snapshot of the tree. Twice is a trap rather than an accident, so the fix is that the path is no longer written down anywhere: `meshbay-hub migrate` asks the installed package where its own migrations are, which is correct for the RPM, the DEB, a venv and a checkout. The build stages no `alembic.ini`; the repo keeps its own for `alembic revision` and for deploy scripts that already work. `env.py` now prefers a URL the caller resolved over re-reading the environment itself, so `migrate --config` connects with exactly the string the server will — one resolution, not two that agree until they do not. Six tests, three of which fail against the unit as it was. They read the directives rather than the file, because searching the whole thing finds the comment explaining a directive and calls that the directive.

* fix(hub): refuse to start with more than one workerChristophe Besson2026-09-121-0/+22
| | | | | | | | | | | | | | | `_connected_nodes`, `_node_groups`, `_webrtc_answers` and the relay registry are per-process dictionaries. With two workers a node registers in one and the WebRTC offers for it arrive at the other, so the symptom is a node that is intermittently offline for half its members — which reads as a network problem, a NAT problem, anything but a configuration line. `server.workers` has always defaulted to 1 and the constraint was written down nowhere. One line at startup, and a function rather than an inline check so it can be tested.

* feat(hub): leaving a group, a cap on public ones, and hosting as a preconditionChristophe Besson2026-08-161-1/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Leaving is its own endpoint rather than a relaxation of the owner's removal check — an authorization rule with an exception in it is the one that gets read wrong later. The owner cannot leave: the group would be left with nobody able to admit, edit or delete it, which is the answer removal and account deletion already give. Public groups are capped at ten live ones per owner. They are the ones that cost other people something — listed in Discover, joinable by anyone — so a script that opens hundreds fills the directory for everybody. Private groups are invisible to non-members and are not capped. Hub staff are exempt; the cap is anti-spam, not a rule about running an instance. Creation is the only place it can be checked, and deliberately so, because PATCH refuses to change visibility at all. A group is now listed only once a node has announced that it hosts it. Before that it has no files, no key and nothing to connect to, so showing it to a member produces a name they cannot open and cannot be told why; its owner still sees it while they set the node up. `meshbay-hub prune-groups` collects the ones that never got a node, meant for cron, with --dry-run. The migration backfills hosted_at from created_at: without that the first run would have deleted every live group. Presence rides on the group list itself, read from the signaling registry the hub already keeps — no poll, no timer. It says a node is connected *to the hub*, which is not a promise that this browser can reach it and not something a dishonest hub could not fake; the client downgrades it on a connection it tried and failed, which is the evidence that concerns the reader.

* feat(hub): add production hub — config, auth, API routers, testsChristophe Besson2026-08-091-5/+26
| | | | | | | | | | | | | config.py: TOML + env var priority. auth.py: Argon2id passwords, JWT EdDSA with jti, refresh token hashed (blake3). Routers: hub (info/pubkey), users (register/login/refresh/pubkeys), nodes (announce/get), groups (create/gek-bundle/gek-retrieve). Rate limiting via slowapi. app.py factory with lifespan. All 40 tests pass (SQLite in-memory, no PostgreSQL required). Fix: remove tests/__init__.py to resolve namespace conflicts. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* chore: initialize monorepo structure for MeshBayChristophe Besson2026-08-091-0/+17
3-package layout: meshbay-common (shared crypto/protocol), meshbay-hub (FastAPI server), meshbay-node (local daemon). Includes validated POC spikes 1-6 in poc/, architecture drafts v1/v2 in docs/, and CLAUDE.md project conventions. All cryptographic primitives extracted from POC into meshbay_common/crypto.py (GEK wrap/unwrap, chunk key derivation, keystore encryption, chunk signing).
