 5. User clicks Apply → TUI POSTs `/rpc/apply` → loader's `apply` calls `buildDialogPayload`, mutates storage via `mutateAccounts`, and returns updated knobs for the TUI to re-render.
 
+**`/openai-reset` credit redemption:**
+
+1. The account list reuses each account's valid L1 access token to fetch `wham/usage` and reset-credit inventory in parallel, producing a per-account preview. Only exhausted accounts with an applicable, eligible credit and a stable ChatGPT account identity can continue.
+2. Selecting an account opens an explicit L2 confirmation bound to its stable `chatgptAccountId`; the dialog states that one reset credit will be spent and that the action is irreversible.
+3. Confirmation resolves the target again and rejects the redemption if its ChatGPT identity no longer matches the bound identity.
+4. A new attempt re-fetches quota and credits and re-checks exhaustion and applicable-credit preconditions immediately before claiming a credit. Under the persisted-pair retry rule (3a), an explicit retry instead requires an active in-flight attempt and reuses its `creditId` and `redeemRequestId` pair.
+5. `consumeResetCredit` sends the explicit credit ID and redemption UUID to the consume endpoint in a POST bounded by a 60-second timeout.
+6. Terminal server outcomes (`reset`, `already_redeemed`, `nothing_to_reset`, `no_credit`) clear the matching in-flight pair and persist `lastOutcome`; only the credit-spending `reset` and `already_redeemed` outcomes start cooldown. HTTP and ambiguous outcomes preserve the pair so a retry can reuse the same identifiers; an expired unreconciled pair requires an explicit replay, while corrupt local state is recorded as locally ambiguous instead of issuing a consume request.
+7. A successful or already-redeemed outcome runs the normal targeted quota refresh for the selected account, pushes the result through `QuotaManager`, refreshes the sidebar snapshot, and fetches the remaining applicable-credit count.
+
+Verification debt: server-side deduplication of a repeated `redeem_request_id` is assumed from Codex client source, not live-verified. Before trust expands beyond operator-confirmed interactive use, one safe check must re-POST a consumed UUID and `creditId` and verify an `already_redeemed` response with no second count decrement.

 **Versioning & build:** `packages/opencode/src/version.ts` exposes `PackageVersion` (currently `0.3.4`); the TUI plugin header reads `package.json` at runtime via `import.meta.url` so the version badge tracks the package version without baking it into the dist. Use `packages/opencode/scripts/build-tui.ts` during the build to precompile TUI Solid JSX source files into `packages/opencode/src/tui-compiled/` using the `@opentui/solid` compiler transform, binding Solid/OpenTUI imports to the host's virtual runtime registry (`opentui:runtime-module:<specifier>`) so the TUI shares the host's single Solid/OpenTUI runtime. The release pipeline is tag-driven (`.github/workflows` + `scripts/release.sh`); see `README.md` for the exact command surface.
