parseModel already tolerates a model JSON with an id but no providerID (a real shape
opencode can write). checkModelMatch's providerMatches check did not: a provider-
prefixed profile whose id matched but whose evidence had no providerID was reported
as a mismatch and quarantined on incomplete data, which acceptance rule 4 forbids.
Compare the provider only when BOTH the profile requested one AND the evidence has
one. A genuine id mismatch is still caught either way — narrows the check, does not
disable it.
opencode does not fail on an unknown -m <model> flag — it silently falls back to a
default model, which can be a paid credential. Extends the existing late-resolve
path (#209's SessionManager -> handle.agentSessionId() re-poll) so that once the
opencode session row exists, OpenCodeSessionDiscovery also reads its `model` JSON
column and OpenCodeLauncher's SessionAwareHandle compares it against the profile's
configured model.
Comparison rule: split the profile's model on the first '/' into provider+id. Compare
id always; compare provider only when the profile specified one. A bare model name
with no '/' matches on id alone. Absent/unparseable evidence is UNKNOWN, never a
mismatch, so a working profile is never quarantined on missing data. A real mismatch
logs an ERROR naming both models and the profile, then quarantines through the
existing ExhaustionSink path (wired via an AtomicReference forwarding sink in
Fleetd.java to break the sessions/workers/adapters construction cycle).
