The first AgentScope::PerSubject system agent, and the reason that scope
exists. Once a night, for each person with a supervision edge, it reads every
message that person and the assistant exchanged since the previous review —
across all their conversations — and writes one report for the people who
supervise them.
Schema (all registry except reports):
- supervision(subject_user_id, supervisor_user_id): the generic §0.1 edge,
answering both 'whom does a background agent look at' and 'who may read
what it produced', with real FKs so deleting a user cascades both ways
- system_agent_coverage(agent_id, subject_user_id, covered_through): the
per-subject watermark that makes 'everything since last time' a window —
neither system_agent_runs (history for humans) nor system_agent_state
(advances before the work), and advanced only on a completed pass so a
crash re-covers instead of skipping
- reports (owner schema, the second two-homes table after memory_docs):
instance rows land in system.db, deliberately cleartext to the box owner,
who is the intended reader (§2); the subject cannot see them structurally
The pass reads the subject's database inside a supervisor's runtime, so the
ephemeral session and run row land in the watcher's file; iteration is over
subjects, so two parents watching one child get one review; and the subject
need not be logged in when their space is unencrypted — via the new
UserManager::open_unencrypted, which refuses an encrypted user outright (no
key to be had) and never registers the pool as unlocked.
The agent declares the new AgentMeta flag allow_tools: false, so its turn
gets an empty tool registry — nothing for a prompt injection in the
transcript to call — and produces its report as its final assistant message,
read back from chat_history and parsed (NOTHING_TO_REPORT sentinel, no row on
quiet days). chat_history::conversation_window is the transcript query; its
four filters (non-ephemeral, depth 0, non-synthetic, non-empty) each guard a
specific way the review would otherwise be wrong, and tool calls are absent
by construction.
Cadence is Run at (hour) rather than Interval — 4am local by default — with
due-ness answered inside has_work against the coverage watermark, so a
machine off for three days covers the whole stretch in one pass. Reports
announce ReportCreated on the system bus (no subscriber yet). run_ephemeral_turn
gains a per-pass system_substitutions map, which the review uses to hand the
model the subject's profile under __SUBJECT_PROFILE__ — the system-context
substitutions describe the session owner, the wrong person here.
docs/system-agents.md gains the conversation review section; CLAUDE.md
documents the scope, the tables and the tool-less design.
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
