feat(work): opencode-go usage-threshold fallback (5h/weekly/monthly) - #539
Conversation
Track the active OpenCode Go subscription's quota windows via the official GET /zen/go/v1/usage endpoint, authenticated with the opencode-go API key from opencode's auth.json — the OpenCode Go counterpart to claude_usage's Claude Max 5h/7d gate. resolve_agent now computes a fallback candidate for opencode primaries too (symmetric to claude-code), pick_implementer_agent is agent-agnostic, and the call site selects claude_over_threshold vs opencode_go_over_threshold by primary agent. Fails open and caches 5m, same as the Claude path. Agentflare-Agent: 1 Agentflare-Branch: feat/opencode-go-usage-tracking

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to When usage thresholds trigger a fallback to another agent, an incompatible model identifier may be forwarded and cause the implementation to fail before execution; merge should wait for a fix or explicit owner acceptance.

build_extra_args call to use implementer_agent instead of agent_enum, preserving
agent-specific execution setup after pick_implementer_agent selects a fallback.
- Around line 372-374: Clone the rotation map before the fallback probe and pass
the clone to the second agent_registry::route call, leaving the real rotation
unchanged. Preserve the existing agent filtering behavior in the route chain and
ensure only the primary routing path advances rotation.

…llback probe - build_extra_args, the headless-mode gate, the log line, and classify_and_cooldown now key off implementer_agent (the agent that actually runs) instead of agent_enum, so a usage-threshold fallback no longer passes the wrong agent's flags. - The fallback probe routes on a clone of the rotation map so a what-if probe never advances a rotate=true rule's counter.

…rimary A usage-threshold fallback switches the agent (e.g. claude -> opencode), but args.model was forwarded unchanged — Claude model IDs aren't valid opencode 'provider/model' identifiers.

Summary
Track the active OpenCode Go subscription's quota windows (rolling 5-hour / weekly / monthly) and use them to gate the SDD implementer agent's router fallback — the OpenCode Go counterpart to \claude_usage's Claude Max 5h/7d gate (item #500's inverse).
What
esolve_agent\ now computes a fallback candidate for \Opencode\ primaries too (symmetric to \ClaudeCode); \pick_implementer_agent\ is agent-agnostic; the call site selects \claude_over_threshold\ vs \opencode_go_over_threshold\ by primary agent.
Test plan
esolve_agent\ (14) + \pick_implementer_agent\ (5) all pass
