v1.0.0

Multi-vendor support, a unified price list, and version-aware pricing. This is a breaking release — read the upgrade notes.

⚠️ Upgrading from 0.8.x

1. Remove the old extension before loading this one. chrome://extensions → remove the 0.8.x card → Load unpacked → select the extension folder. Two copies would both crawl and double-count.
2. Your usage history is kept. opencode crawl data lives in OPFS on the opencode.ai origin, independent of the extension ID. After loading, open your opencode.ai Usage page and click Crawl Now to rebuild it.
3. Your settings reset once. This release pins a stable extension ID (key), which changes the storage namespace one time. Re-set: the peak-reminder toggle/model, workspace display names, enabled vendors, and default crawl vendor.
4. Custom Rate Settings from 0.8.x are not carried over. Costs fall back to the shipped price tables; edit them in Settings → Pricing. (The 0.8.x rates JSON is not importable by 1.0.0.)
5. Local DB imports must be redone. Records imported with tools/import-local.mjs are stored in extension storage (not opencode.ai) and do not survive the ID change — re-run the tool and Import Usage again.

Added

• Multi-vendor usage: opencode, OpenRouter, DeepSeek, CommandCode, MiMo — separate pipelines, one dashboard. Enable per vendor in Settings → Vendors; each optional host is requested on first enable.
• Unified pricing: one user-authored price list for every vendor, keyed by <source>:<model>, with per-model rate groups and versioned rates. Recompute costs at any time.
• Fingerprint grouping: rate groups are derived from a model fingerprint (series / version / variant), so spelling, routing-prefix and date-stamp variants collapse into one group. Unenumerated spellings still resolve through a fallback key.
• Version-aware pricing: each rate carries effective and retired versions; peak windows come from the version in force, so a superseded promo stops announcing. A retired version no longer prices history.
• Import Usage: a single entry that accepts MiMo XLSX, opencode local JSON, vendor exports, and backups (multi-select a mix of types).
• Settings → Database: lists every usage store and where it lives (OPFS vs chrome.storage.local), with per-record and per-store deletion for extension-owned stores. Records are grouped by bucket membership, so each one appears exactly once. Backup export lives here.
• Export Backup: one button, two disjoint files — opencode-usage_settings_*.json (settings + pricing) and opencode-usage_records_*.csv (every record, every source, with lossless raw). Import restores either.
• Stable extension ID: a key in the manifest pins the ID so the folder can be moved/re-cloned without losing data.
• Storage migrations: storage carries a schemaVersion and additive, idempotent migrations run at startup.
• How it works diagrams: each pipeline section renders a self-drawn SVG flowchart alongside its notes.
• Automatic per-vendor price presets and a price-watch workflow.

Changed

• Cost source is per vendor: token-derived by default, or vendor-reported spend where trusted (OpenRouter, CommandCode).
• Records are canonical and immutable; costs are recomputed on render, so a corrected price retroactively fixes history.
• Dashboard settings are split into General / Vendors / Pricing / Database / How it works. The local-import how-to moves to How it works, Backup to Database, and General keeps only crawl and display options.
• The popup and dashboard share one copy of the switch, time-reminder card, heatmap and custom-select/resizable-editor widgets, with no visual change.
• Guardrails: CI verifies the generated manifest and registry, runs the test suite, and fails if the manifest version falls below the latest tag.

Fixed

• Day-granular records billed the oldest rate version; the migration backfills each map's time/v (DeepSeek flash cache-hit $0.028 → $0.0028).
• The pricing board no longer lists a structurally-billed model as Unassigned — pricing and the board resolve a chip through one fingerprint rule, and structurally-pinned chips are marked.
• Restored the vendor alias folds lost in the fingerprint refactor (deepseek-chat/reasoner, the flash expiry label, and the muse-spark contributor lines).
• The peak-reminder picker drops retired and flat-version models and heals a stale selection.
