 /**
- * Preset model for the opencode launch — change the preset by editing this
- * constant. OPS78: routes through the Vercel AI Gateway (cache/stability/
- * failover) instead of the direct provider. OPS82: the preset is the cheaper
- * `-0731` flavor (input $0.076/M vs $0.13/M); the low/high/max variants are
- * exposed by the `provider.vercel` override in the global opencode config
- * (`~/.config/opencode/opencode.jsonc`, outside the repo — OPS89).
+ * Preset model for the opencode launch — fallback comum aos 3 repos do fluxo
+ * (infra-solla, teqo, iara-pwa). Override sem editar código: global via
+ * `export OPENCODE_WORKTREE_MODEL=…`, ou por repo na chave
+ * `OPENCODE_WORKTREE_MODEL` da `.forgejo/worktree.env`. Ex-OPS78/OPS82: o
+ * preset era o flavor `-0731` via Vercel AI Gateway; voltou ao provider
+ * direto porque o gateway está sem créditos (erros "positive credit balance"
+ * em 24/08/2026) e porque unificar o default reduz a sobrescrita confusa de
+ * seleção de modelo do TUI (opencode issues #8349/#13456).
