On ARM64 devices (e.g. Raspberry Pi 4), resolvePluginProviders takes ~20s
on first call. Three bugs cause this cost to be paid repeatedly:
1. ensureOpenClawModelsJson readyCache fingerprint includes models.json
mtime. After a write, the stored fingerprint (pre-write mtime) never
matches again, forcing every caller to re-run planOpenClawModelsJson.
2. readyCache has one entry per file path. Agents with different configs
(e.g. main agent vs active-memory subagent) overwrite each other's
entry, so neither benefits from caching.
3. resolveExplicitModelWithRegistry calls shouldSuppressBuiltInModel →
resolveProviderPluginsForCatalogHooks on every agent run. The internal
cache key includes the full config, so callers with slightly different
configs each pay the full provider-load cost.
Fixes:
- Remove modelsFileMtimeMs from fingerprint (bug 1)
- Add noopCache to MODELS_JSON_STATE keyed by (path, mtime) — a noop
result is config-agnostic, so any caller can reuse it (bug 2)
- Cache resolveExplicitModelWithRegistry by (provider, modelId, agentDir),
stable for the lifetime of a gateway session (bug 3)
Measured on Raspberry Pi 4 (ARM64):
active-memory subagent preprocessing: 66-75s → ~3s (warm)
active-memory total elapsed: ~96s → ~14s (warm)

* fix(agents): resolve model aliases in sessions_spawn
normalizeModelSelection() only trims the input — it never resolves
aliases through the model alias index. When a user passes an alias
like 'opus' to sessions_spawn, the child session gets patched with
the raw string, which the gateway cannot match to any provider.
Add resolveModelThroughAliases() to check bare strings against the
configured alias map before returning from
resolveSubagentSpawnModelSelection().

* refactor: address review feedback on alias resolution
- Accept pre-built ModelAliasIndex instead of rebuilding per call
- Narrow helper signature to (string, ModelAliasIndex) → string
- Remove unreachable ?? raw fallback
