dguiducci da0830aefa feat: an hour-precision clock that says so, and a cron tool that names the real timezone
Nightly Build / build (push) Successful in 7m30s
The datetime block claimed second precision it never had. It is built once per
request and a turn can run for minutes, so `17:54:31` is a lie by the time the
model reads it — and the model, having no way to know, wrote cron expressions
from it.

Rounding was already there but configurable (`round_minutes`, shipped at 60)
and justified by the prompt cache. That justification was false: the block is
the LAST system message, after the whole conversation, so the cached prefix is
identical from turn to turn whatever the timestamp says. Rounding buys nothing
for caching today.

So the knob goes and the granularity becomes part of the contract: always
truncated to the hour, stated in words, with a pointer to `date` for the cases
that need the minute. `DatetimeConfig` keeps only `enabled`.

- truncation happens in the DISPLAYED zone, not on the UTC epoch: +05:30 zones
  would otherwise render 20:30 — an hour off and not on an hour boundary, which
  reads as precise again.
- the weekday is spelled out. "next Tuesday" is a far more common ask than the
  minute, and weekday-from-date is exactly the arithmetic models get wrong.

Also fixes a real bug found on the way: `execute_task` told the model, twice,
that cron expressions are evaluated in Europe/London — hardcoded, while
TaskManager uses the configured timezone. On a non-UK box every scheduled job
was written against the wrong clock. The description now names the zone the
scheduler actually uses (`TaskManager::timezone_name`), and the assistant's
AGENT.md stops repeating the literal.

CLAUDE.md: record that the instance is in production. The greenfield licence has
expired — schema changes need a versioning mechanism, and per-user SQLCipher
files mean it cannot be a boot-time sweep.

dguiducci baf68878e4 fix: stop shrinking conversations behind the user's back — both automatic context guards ship off
Nightly Build / build (push) Successful in 7m35s
The shipped default combined a sliding history window with no compaction, which
is the worse of the two available trades in both directions it is measured on.

`max_history_messages: 30` is a sliding tail window (`projection::window` —
`drain(..len - max)`). Past 30 messages it drops from the head on *every* turn,
so the prompt prefix changes on every single request and every provider that
caches one (Anthropic breakpoints, OpenAI automatic prefix caching) misses every
time. It also drops those messages with no summary standing in for them: silent
amnesia, not just a cold cache. Compaction rewrites the prefix once per
compaction and leaves a summary behind — yet it was the half that was commented
out, while the window's own doc-comment already said the two were exclusive.

Both are now `Option` and both ship unset, so nothing shrinks a conversation
unless a human types `/compact`.

Which surfaced the real bug: `/compact` did not work either. The compactor was
`Option<Arc<ContextCompactor>>` keyed on the config section existing, so
commenting out `compaction:` disabled the manual command too — `force_compact`
returned `Ok(false)` and the chat answered "compaction disabled". Manual
compaction is a command a user types; it cannot depend on an admin having filled
in a token threshold. The compactor is now built unconditionally and
`threshold_tokens: Option<u32>` arms only the automatic pass; `try_compact`
early-returns without it, `force_compact` deliberately never consults it.

The projection accordingly yields to the *automatic* pass rather than to the
compactor's existence (`LoopConfig.auto_compaction_enabled`), so a configured
message cap is not silently voided by `/compact` merely being available.
`CompactionConfig::Default` is hand-written for the same reason `RoleAttrs`'s is:
a derived one gives `keep_recent: 0`, which would compact away every recent
message on any box omitting the section — now the default.

Also fixes two documentation bugs in the same file: `event_triage` was documented
nested under `llm:`, where it parses fine and is then silently ignored (it is a
top-level field), and `datetime` was documented twice with conflicting examples.

A new test asserts the shipped default actually deserializes and that both guards
are off — a field the default omits must be genuinely optional, or a brand-new
install fails to boot.

Automatic compaction returns later, triggered off the resolved model's own
context window instead of a hand-tuned token count that cannot know which model
is answering.

dguiducci 046f060fcd rename the TIC system agent to event triage
Nightly Build / build (push) Successful in 7m16s
TIC said nothing about what the agent does, and named the wrong thing: the
tick belongs to the scheduler, which is generic and lives outside it. The
agent's only decision is whether an incoming event deserves an interruption
— it sorts, it never acts — so it is now event-triage, matching the
functional naming of the two memory lints.

- agents/tic/ -> agents/event-triage/, module tic/ -> event_triage/,
  TicManager -> EventTriageManager, TicConfig -> EventTriageConfig
- agent id and chat source: "tic" -> "event-triage"
- config keys: tic.* -> event_triage.*, and the config.yml section tic: ->
  event_triage: (greenfield: previously set values fall back to defaults)
- i18n en/it/fr: Event triage / Triage eventi / Tri des evenements; dropped
  the stale "TIC sessions" mention from the debug-pages description
- docs/system-agents.md, docs/index.md, docs/settings.md, CLAUDE.md, SKALD.md

dguiducci 178a38357e feat(users): UserManager with per-user SQLCipher, and extract skald-core crate
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.
