feat(usage): add OpenCode usage and tokens - #10926
Conversation
The Usage page only aggregated Claude Code, Codex, and Grok Build; OpenCode turns were invisible even for users whose main driver is OpenCode. Follows the existing scan pattern: the environment reads OpenCode's own on-disk store rather than T3 Code's projections. OpenCode keeps every message as a row of the 'message' table in <data dir>/opencode.db, so the scan opens the database read-only (WAL-safe against a running OpenCode), folds rows through a pure parser, and reports a 'failed' source when the store cannot be read. The data dir resolves per OpenCode's own XDG rules. No scan-cache or resume machinery: the window filter runs in SQL and a retried turn updates its row in place, so there is nothing to dedupe. Legacy pre-SQLite storage/** JSON is deliberately not scanned: current OpenCode reads and writes only the DB, and scanning both would double count on migrated machines. USAGE_CONTRACT_VERSION bumps to 6; USAGE_MERGE_COMPATIBLE_SINCE stays at 4 because the change is additive, so older environments keep merging. Model: openrouter/z-ai/glm-5.3-flash. Harness: OpenCode (T3 Code).

…t loop CodeRabbit flagged that readOpenCodeUsageRecords ran the synchronous node:sqlite query and every row's JSON.parse in one blocking slice; Effect.promise offloads nothing, so a years-deep store would freeze the server loop behind a usage page load. Reads now walk rowid pages (direct B-tree seeks, no OFFSET rescan) of 1000 rows and yield to the macrotask queue between pages, the same interleaving the streaming JSONL reader gets from its I/O awaits. time_created carries no index, so it is filtered per row in the page loop. Model: openrouter/z-ai/glm-5.3-flash. Harness: OpenCode (T3 Code).

CodeRabbit flagged that rowid paging returned insertion order, and a backfilled or clock-adjusted message can hold a later rowid with an earlier time_created. Records are now sorted by time_created with rowid as the tie breaker before returning, keeping the paging cursor and its loop yields. Model: openrouter/z-ai/glm-5.3-flash.

What Changed
OpenCode is now a first-class usage source, following the exact playbook the grok addition (v5) used:
UsageProviderKindgains"opencode".USAGE_CONTRACT_VERSIONbumps to 6;USAGE_MERGE_COMPATIBLE_SINCEstays at 4 because the change is additive, so v4/v5 environments keep merging instead of showing stale.parseOpenCodeMessageDatareducer plus a newopencodeUsageStorethat reads OpenCode's own message store (<data dir>/opencode.db,messagetable) read-only vianode:sqlite- WAL-safe against a running OpenCode, no scan-cache/resume machinery (the window filter runs in SQL; a retried turn updates its row in place, so there is nothing to dedupe).UsageServiceresolves the data dir per OpenCode's own XDG rules and reports a newfailedsource status when the store cannot be read, distinct frommissing.PROVIDER_PRESENTATIONentry (existingOpenCodeIcon); charts, tables, environment filter, and cross-environment duplicate-source dedup adapt viaPROVIDER_ORDERand fingerprints.PROVIDER_ORDER/labels/colors extended, with a light-mode-safe indigo.docs/user/usage.mdprovider list mentions OpenCode.Token mapping was verified against real stores: OpenCode's

OpenCode appears as a new band/row in the web charts and tables and in the mobile chart, using an indigo accent (the only hue in the otherwise white/orange/gray palette). Can add before/after screenshots on request.
