The honcho memory sink needs to observe every user's completed chat turns
from one subscription, keyed by ChatEvent.user_id. But each UserContext
minted its own per-user ChatEventBus, so a single global subscription saw
nothing.
- UserContext now publishes onto the shared Runtime.event_bus (the one
Skald::subscribe_chat_events reads) instead of a fresh per-user bus.
- Expose that bus to plugins as PluginContext.chat_bus (distinct from
system_bus, which carries only infra lifecycle events).
- plugin-honcho subscribes via ctx.chat_bus.

- Add MoonshotProvider and MoonshotCodeProvider (OpenAI-compatible)
- Extract `fetch_openai_models()` and `build_openai_llm()` shared functions,
deduplicating model-listing and client construction across OpenAI,
OpenRouter, DeepSeek, LM Studio, and Z.AI providers
- Add `lists_models` field to `ProviderUiMeta` — drives frontend model
picker dynamically instead of hardcoded `type_id` list
- Port DeepSeek, LM Studio, OpenRouter model listing to `fetch_openai_models`
- Set `lists_models: true` on Z.AI provider (missed in prior pass)
feat(mcp): named key placeholders {SECRET:name}/{ENV:name} in connector URLs
- `apply_key_placeholder` now accepts an `env` map alongside `api_key`
- Named tokens resolve from the connector's described `env[]` fields,
with `{SECRET:name}` falling back to `api_key` for backward compat
- Replace `substitute_secret_tokens` with `substitute_named_tokens`
- Unresolved tokens are left in place (visible misconfig) rather than
silently producing a wrong URL
fix(ui): connector detail hides generic API key when schema has secret
fix(ui): model picker uses `lists_models` from provider types endpoint
Realizes blueprint §6: each user gets a permanent Docker container
(skald-{userid}, our own skald-runtime image with python+node) as their
execution sandbox. Docker is now a hard requirement — a missing daemon fails
Skald::new and the process exits at boot.
- ContainerManager (crates/skald-core/src/container/): docker availability
check, builds skald-runtime from the embedded Dockerfile, reconciles one
running container per active user at boot, stops them at shutdown, and
ensure/remove on user create/delete. Shells the docker CLI (no client crate).
- UserFs (core-api): pure value type carried in ToolContext, mapping the agent's
single namespace — ~/ → homes/{userid}, shared/{X}/ → shared/{X} (membership),
user-memory/ + shared-memory/ → SQLite — to host and container paths.
- execute_cmd now runs inside the caller's container via `docker exec`.
- fs-tools resolve every physical path through UserFs to the per-user host
workspace, host-side, with fail-closed symlink/`..` containment
(resolve_host_path: canonicalize + prefix-check). grep_files resolves its root
the same way but stays disk-only.
- shared_folders + shared_folder_members (registry, junction table with
can_write) back the shared-folder membership that drives both the container
mounts and the shared/{X} routing.
- Threading: UserContext.fs → ChatSessionManager → handler → ToolContext.fs.
Per-user MCP servers do not yet run in the container (next round).
Two changes developed together in one session; they share the same module
structure (db/mod.rs, the core lib root) and only compile together, so they
land as one commit.
## UserManager + per-user encryption (§9/§11)
New `users::UserManager`: owns the system.db pool plus a map
`userid -> SqlitePool` of unlocked databases. The pool *is* the unlock token —
its connect options carry the DEK as SQLCipher's raw key, so an open pool means
the key is in RAM until restart and dropping it re-locks (§9). Knows nothing
about cookies.
New `crypto` module: envelope encryption. A random 256-bit DEK encrypts
`{userid}.db`; `users.database_password` holds it sealed with AES-256-GCM under
`Argon2id(password, salt)`. The AEAD tag is the password verifier — one
derivation both authenticates and yields the key, so encrypted users store no
second hash. Cleartext users store the Argon2id output directly, compared in
constant time. Argon2 runs in spawn_blocking behind a 2-permit semaphore
(256 MiB per derivation).
- SQLCipher via `libsqlite3-sys` `bundled-sqlcipher-vendored-openssl`, pinned
<0.38 so it unifies with the one sqlx-sqlite links (a newer copy would apply
the feature to a SQLite sqlx never uses). OpenSSL is vendored and static, so
the binary stays self-contained.
- Schema split into `create_registry_tables` (instance-wide, no user key) and
`create_owner_tables` (one owner's content, identical in every file). No FK in
the owner bucket may reach the registry — enforced by a standalone test.
Dropped `chat_history.model_db_id` (write-only, and the only registry-crossing
key); moved `projects`/`project_tickets` into the owner bucket.
- Provisioning invariant: the file is written before the row, deleted after it,
so a crash leaves an orphan file, never a user without a database. `open_db`
never creates: a missing file is an error, not a silent empty database.
Not consumed yet: no login, call sites still use the shared system.db pool.
## Extract crates/skald-core
The headless core moves out of `src/` into its own crate; `skald` (server) and
the coming `skald-setup` are shells around it. Two dependencies on the shell
were inverted rather than dragged along, so the core names neither Tauri nor any
concrete plugin:
- `Plugin::tools(self: Arc<Self>)` — plugins contribute tools through this hook
(sibling of `http_router`), so the core no longer downcasts to
`MobileConnectorPlugin`.
- `tools::restart::set_restart_handler` — the desktop shell installs its
teardown-and-respawn; the core defaults to the supervisor exit code. The core
loses its `desktop` feature.
- `boot`'s stdout formatter moves to the binary (`src/boot_format.rs`); the core
only emits tracing events.
All 79 core tests pass; the binary boots and serves in a clean directory, and
the mobile-connector tools still register through the new hook.
