config: nest routing config under experimental.routes (models, providers, windows, schedules, tuning, log, settings) with a normalize compat shim for the flat keys #1140
Description
Direction (Drew, 2026-10-31)
Restructure the routing config surface from the flat experimental.model_route_* key family into a single nested schema:
"experimental": {
"routes": {
"models": today's experimental.model_routes,
"providers": experimental.provider_routes (PR #1134),
"windows": today's experimental.model_route_windows,
"schedules": today's experimental.model_route_schedules,
"tuning": today's experimental.model_route_tuning,
"log": today's experimental.model_route_log,
"settings": the routing-constants block (bench / demotion / quota-gate / escalation), when it lands
}
}
Staging decision (Drew, 2026-10-31 22:11 CDT)
STAGED, not big-bang. The flat rename (synthetic_providers -> provider_routes) lands first on PR #1134. This conversion happens after BOTH provider_routes (#1134) and the constants/settings block have landed, so exactly one migration moves a settled surface.
Why a compat shim is required
The fork's config loader is not the only reader of these keys:
bin/opencode-route-proxy.mjs(developing-today/code) parses the raw JSONC and resolvesmodel_routesitself — no shared code with the fork.- OpenChamber's
validateModelRoutesreads the same flat keys.
A hard rename breaks both silently (proxy finds no routes; validator validates nothing). The fork's normalize layer already translates legacy keys (disabled_providers -> policies, experimental.policies -> policies, experimental.mcp_timeout -> mcp) — this conversion follows that exact pattern.
Acceptance
- Nested keys are the canonical schema; the routing plugins read the nested shape after normalization.
- Every flat key (
model_routes,model_route_windows,model_route_schedules,model_route_tuning,model_route_log,provider_routes) normalizes into the nested shape with a deprecation diagnostic; resolved config is identical either way (tests both directions, including a config that mixes flat and nested — nested wins, conflict is diagnosed). - Follow-on reader updates are filed and linked from here when this lands: the route proxy (developing-today/code) and OpenChamber's validator learn the nested shape; the flat shim is removed only after both stop needing it.
- The live fleet config migrates in the same pass as the deploy of this change (config + readers move together); until then the shim carries it.
Acceptance criteria
- Routing config is readable in the nested
experimental.routesshape (models/providers/windows/schedules/tuning/log/settings) after both prerequisite pieces land (PR feat(core): provider routes — provider-level pools with ordered/round-robin/weighted selection #1134 provider_routes; the feat(routes): experimental.model_route_settings — route machinery constants as config, defaulted to current values #1141 settings block). - Flat
experimental.model_route_*keys keep working through the normalize compat shim, including external readers named in the body. - Config tests cover nested, flat, and mixed inputs.

Requirement addendum (Drew, 2026-10-31 22:13 CDT)
When this conversion is designed, the auxiliary constructs —
windows,schedules, and the rest of theroutes.*family — must be able to target providers and models symmetrically, in both route kinds:model_route_schedulesalready match by providers/models/targets/routes inside the model-route world; the provider-route side is the new surface.)settingsapplication andtuning: nothing inroutes.*may be able to name a model but not a provider, or a provider but not a model, without a stated reason in the design.Acceptance addition: the conversion design includes a targeting matrix (construct × dimension: provider / model / pair / route, for model routes and provider routes) with every cell either supported or explicitly justified as out of scope. The provider-route grammar from #1134 (members are bare provider ids; selection + weights only) has no per-member window/schedule surface today — closing that is part of this issue's scope, or a linked follow-up filed from it.

Intake review — fleet monitor
Related: #1141 (settings block — a staging prerequisite), PR #1134 (provider_routes rename — the other prerequisite). No merged PR references this issue yet at intake.
Notes: explicitly STAGED per Drew's 2026-10-31 22:11 CDT decision — do not start until both prerequisites land; the compat shim is required because external readers (bin/opencode-route-proxy.mjs in developing-today/code) parse the flat keys.
Suggested approach: normalize-on-load (flat → nested) in one place, keep writers on the nested shape only.
Risks: double-normalization or a reader bypassing the loader; mixed flat+nested configs need a defined precedence, covered in the acceptance criteria.

provider_routesis live —packages/schema/src/config/experimental.tsnow carriesprovider_routes: ConfigModelRoutes.ProviderRoutes).Outstanding work, verified by direct read of
packages/schema/src/config/experimental.tson main855ec25f: theInfoclass still exposes the flat family —model_routes,provider_routes,model_route_schedules,model_route_windows,model_route_tuning,model_route_log,model_route_settings— and there is no nestedroutesblock and no normalize compat shim yet. So exactly one migration now moves a settled surface, as the staging decision intended.Cross-repo set remainder (recorded, not ported):
bin/opencode-route-proxy.mjsin developing-today/code parses the raw JSONC flat keys (per the issue body) — the compat shim must keep it working, and any eventual flat-key removal is owed in code as a set remainder from this issue. No separate code issue is filed for it.Done looks like:
experimental.routes.{models,providers,windows,schedules,tuning,log,settings}accepted as the nested schema; flat keys keep working via a normalize-on-load shim; windows/schedules and the rest of theroutes.*family can target providers and models symmetrically in both route kinds (Drew's 2026-10-31 22:13 CDT addendum); existing configs and the code-repo proxy reader keep working unchanged.Enqueuing a triage packet to

dezren39 commentedon Nov 1, 2026
agent-note:v1 — blocked triage task 4989 as packet_defect. The packet says the fork normalize-on-load shim serves the independent developing-today/code raw JSONC reader, and omits the OpenChamber validator and coordinated reader/config migration in the issue body. A loader shim can preserve flat input for the fork, but cannot make a nested-only raw file readable by independent flat-only readers. Correct the packet scope and acceptance to cover both readers and coordinated rollout before promoting a fix; no code changed.
