The 08-31 lever: model_assignments gains one compound rung —
AGENT_SLUG > ROLE('{role}:{complexity}') > ROLE > GLOBAL — so a
low-complexity task can route to a cheaper tier while coordinators stay
pinned. Structurally opt-in: zero rows means byte-identical routing
(pinned by a named test across every precedence case), the cost_tiered
apply-mode (seeds developer:low→haiku) is reachable only from the
explicit PM-gated endpoint — verified no startup path can apply it.
Overrides are downgrade-only (input-price comparator), allowlisted to
{developer, qa, documenter} — cell_pm excluded per the org's own
coordinator definition and its documented weak-model incidents — and
validated at write time (disabled/unconfigured provider rejected with
remediation; cross-provider-family overrides warn explicitly).
Per adversarial review: the four mode-switch applies now spare compound
rows exactly like agent pins (the 2026-07-17 unscoped-wipe class, new
victim, same fix extended via one shared wipe helper) with panel cache
invalidation + truthful confirm dialogs; preset apply validates the
entire payload BEFORE the wipe (validate-all-first), with a savepoint
crash test proving rollback.
Presets (CEO request): routing_presets table (migration 082) snapshots
the full mix — mode, per-agent overrides, complexity rows — with
save/apply/delete endpoints and a panel preset bar; applying skips
since-removed models with per-entry notes, never silently.
Task complexity threads task_id through _resolve_agent_route at both
call sites; taskless spawns unchanged. 235 backend + 23 panel tests.

"""Routing presets — named, full snapshots of the AI-routing state.
|
|
|
|
Lets an operator save the current routing state (mode + every
|
|
`model_assignments` row: GLOBAL / plain ROLE / compound ROLE(":"complexity)
|
|
cost-tier overrides / AGENT_SLUG pins) under a name and re-apply it later in
|
|
one call, instead of re-picking every per-agent Select. ``payload`` mirrors
|
|
exactly what ``GET /providers`` + ``GET /providers/complexity-overrides``
|
|
already serve, so a preset is "what the card currently shows" — see
|
|
``ModelRoutingService.save_routing_preset`` / ``apply_routing_preset``
|
|
(roboco/services/llm.py). Pure additive new table; no backfill, no data
|
|
migration — applying a preset is the only thing that ever mutates
|
|
``model_assignments`` as a side effect, and only on an explicit call.
