2026-09-20 — OpenCode model pool: verified, Go plan currently erroring

Setup (verified live 2026-09-20 ~09:20 PDT)

opencode 1.18.31 (npm global) + local project copy at C:\Users\fight\Projects\browserclaw-project
Config: C:\Users\fight\.config\opencode\opencode.jsonc — exactly 34 models (8 opencode/* + 26 opencode-go/*), per Tony's brief
Key: OPENCODE_API_KEY present in ~/.config/opencode/.env (masked, not logged)

PASS: opencode/big-pickle, opencode/ling-3.0-flash-fin-free (proprietary free tier)
FAIL (HTTP 500 UnknownError "Unexpected server error" + ref): every Go-plan model tested — glm-5.3, deepseek-v4-flash, grok-4.6, qwen3.8-flash — via any prefix (opencode-go/, opencode/, bare)

opencode-go/ prefix is stale for v1.18.31: opencode-go/glm-5.3 → ProviderModelNotFoundError ("Did you mean: glm-5.3, glm-5.3-flash?"). Correct IDs resolve under opencode/ or bare.
Go-plan backend failures are server-side, not local: opencode.ai/zen/go/v1 has a history of intermittent outages (anomalyco/opencode issue #36889).
Distinct error refs per request (e.g. err_a8828e9a) — new errors each attempt, not a cached config issue.
Config prefix fix NOT applied — waiting on Tony's authorization.

Patched opencode.jsonc: all 26 opencode-go/ → opencode/. Verified: 0 opencode-go remaining, 34 opencode/ entries.
Snapshot: ~/.config/opencode/opencode.jsonc.good-20260920-092315 (rollback point).
Live re-test 09:24 PDT: opencode/glm-5.3 resolves (no longer model-not-found) but still HTTP 500 UnknownError ref err_15953691 at 09:26 — Go backend flaky via CLI (direct API call with x-opencode-session header WORKS, 200, glm-5.3 responded). CLI Go failures are server-side (anomalyco/opencode #36889), not config.

Hermes has native opencode-go plugin (plugins/model-providers/opencode-zen/__init__.py, needs OPENCODE_GO_API_KEY, base https://opencode.ai/zen/go/v1) but it does NOT add x-opencode-session header.
Added pinned custom provider oc-go (26 Go models, discover_models: false, extra_headers.x-opencode-session per-profile UUID) + opencode-go: enabled: false to ALL FOUR profile configs: ashbot, coach, jimmy, leonard.
Snapshots: each config.yaml.good-ocgo-20260920-093345. hermes config check passes all 4.
KEY STEP (user-side, secret guard): copy OPENCODE_API_KEY from ~/.config/opencode/.env as OPENCODE_GO_API_KEY into each profile .env, then hermes gateway restart --profile <p> from a separate shell.
