What

Bump the overlay base from opencode v1.18.29 (7fe9938) to v1.18.30 (3104c14). This brings in 413 upstream commits — the non-overlaid paths flow through automatically at build time; overlaid files were reconciled via three-way merge.

Why

The overlay was shadowing upstream behavioral fixes in provider.ts and transform.ts, blocking:

  • Claude 5.1+ thinking signature binding (anthropicBlockBinding) — prefix changes (compaction, tool updates) would hard-fail
  • Cloudflare AI Gateway native routing — OpenAI Responses API, Anthropic Messages API, Workers AI, third-party REST fallback
  • Vertex AI EU/US continental routing (googleVertexEndpoint helper)
  • 5-minute default timeouts (chunkTimeout/headerTimeout = 300_000)
  • Bedrock ARN passthrough — models configured by ARN were getting broken region-prefixing
  • Azure OAuth resource name fallback, Azure CLI auth
  • GitLab/MergeGateway reasoning variants, DeepSeek v4 Flash topP
  • Cerebras plugin, retry improvements, session affinity headers, and more

How — overlay reconciliation

File Approach
provider.ts Start from upstream v1.18.30. Re-apply 2 additions: defaultModel() provider-availability guard + broadened "deepseek" prefix match
transform.ts Start from upstream v1.18.30. Re-apply 5 additions: Bedrock reasoning-part text fallback, applyBedrockCacheOptions, empty-content guard, Qwen temperature/topP
dialog-connect-provider.tsx Start from upstream v1.18.30 (gets i18n fix). Re-apply all Harmoniqs additions (provider integration, browser OAuth UX, design system tokens)
models-dev.ts No change needed — 3-line comment already preserved

Harmoniqs AI provider

Unaffected. The Harmoniqs provider routes through app.harmoniqs.ai/v1 as @ai-sdk/openai-compatible — none of the provider-specific transforms (Bedrock, Anthropic, Vertex, etc.) fire for it. The gateway handles all format translation.

Verification

  • build:binary ✅ — compiles, smoke test passes, reports v1.18.30
  • drift_gate.mjs ✅ — overlay and manifest in sync
  • Manifest hashes updated for all 3 changed overlay files (patch only, no full-refresh)

Summary by CodeRabbit

  • New Features
    • Expanded Cloudflare AI Gateway support for OpenAI, Anthropic, Workers AI, and other compatible providers.
    • Improved compatibility with Google Vertex regional endpoints, Amazon Bedrock ARN models, and Azure OAuth accounts.
    • Added reasoning and thinking support for compatible Claude, GPT, and DeepSeek models.
    • Expanded language support, including right-to-left layouts, localized desktop menus and attachment labels, and locale-aware pluralization.
    • Added Markdown math rendering for inline and display formats.
  • Bug Fixes
    • Provider connection hints now use localized labels, and stream cancellation errors are handled more reliably.
    • Session lists sort consistently by most recent activity.
    • Codex requests now support residency settings, and GPT model context limits are applied consistently.

📝 Walkthrough

Walkthrough

The pull request updates desktop localization, provider routing and model options, Markdown parsing, session UI behavior, session ordering, and Codex request handling. It also pins the app bundle and extension to upstream version 1.18.30.

Changes

App bundle and extension update

Layer / File(s) Summary
Desktop locale and menu localization
packages/app-bundle/overlay/packages/app/src/context/language.tsx, packages/app-bundle/overlay/packages/app/src/desktop-menu.ts, packages/app-bundle/overlay/packages/app/src/components/*, packages/app-bundle/overlay/packages/app/src/app.tsx, packages/app-bundle/overlay/packages/app/src/i18n/en.ts, packages/app-bundle/manifest.json
The language context adds locale loading, direction and plural support, and native translation callbacks. Desktop menu labels, provider connection hints, and prompt attachment labels use localization.
Provider routing and SDK resolution
packages/app-bundle/overlay/packages/opencode/src/provider/provider.ts, packages/app-bundle/manifest.json
Provider handling updates Vertex endpoints, Azure OAuth resource lookup, Bedrock ARN handling, Cloudflare AI Gateway routing and SDK selection, SSE cancellation, and timeout defaults.
Model option and reasoning transforms
packages/app-bundle/overlay/packages/opencode/src/provider/transform.ts, packages/app-bundle/manifest.json
Model transforms add Merge Gateway options and DeepSeek sampling behavior. They also update Claude thinking bindings, GPT-5 text verbosity, and reasoning-effort handling.
Markdown parser replacement
packages/app-bundle/overlay/packages/ui/src/context/marked-parser.tsx, packages/app-bundle/overlay/packages/ui/src/context/marked.tsx, packages/app-bundle/overlay/packages/ui/src/context/marked-math.test.ts, packages/app-bundle/overlay/packages/session-ui/src/components/markdown-shiki.worker.ts, packages/app-bundle/manifest.json
A new parser module configures KaTeX, Shiki, and external links. Math parsing uses guarded delimiters and preserves source text on rendering errors. The previous parser module and Shiki worker are removed.
Session UI localization and plural labels
packages/app-bundle/overlay/packages/session-ui/src/components/message-part.tsx, packages/app-bundle/overlay/packages/session-ui/src/components/tool-count-label.tsx, packages/app-bundle/overlay/packages/session-ui/src/v2/components/prompt-input/index.tsx, packages/app-bundle/overlay/packages/app/src/app.tsx, packages/app-bundle/manifest.json
Tool count labels use locale-based plural forms. Attachment labels receive a localized fallback string. The app bridge forwards locale and pluralization data to the UI provider.
Session ordering
packages/app-bundle/overlay/packages/app/src/pages/layout/helpers.ts, packages/app-bundle/manifest.json
Root sessions sort by descending updated-or-created time, with an ID tiebreaker. The recent-minute priority is removed.
Codex OAuth and model handling
packages/app-bundle/overlay/packages/opencode/src/plugin/openai/codex.ts, packages/app-bundle/manifest.json
Codex handling reads compute-residency claims and adds a residency header for specified rewritten requests. Model-version matching and GPT-5.5/GPT-5.6 context limits are updated.
Upstream revision and extension pins
packages/app-bundle/manifest.json, packages/app-bundle/scripts/engine_typecheck_gate.sh, packages/extension/opencode.lock.json, packages/extension/test/*
The app bundle and extension metadata pin upstream version 1.18.30 and its base commit. Typecheck allowlist notes and extension version assertions are updated.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve Amicode branding after loading non-English dictionaries.

These overrides apply only to the English base dictionary. merge() in packages/app-bundle/overlay/packages/app/src/context/language.tsx then replaces them with locale entries. For example, the pinned upstream Hindi dictionary supplies “OpenCode” for the app menu, menu accessible name, documentation, and recovery messages. A Hindi user therefore sees OpenCode branding alongside Amicode branding. Apply the brand overrides to the effective locale dictionary while preserving its translated text.

drift-gate PASS, engine typecheck gate PASS, marked-math 8/8.
The overlay_typecheck_gate (#1348, fail-closed) caught the real i18n API
drift the build:binary lane missed. v1.18.30 reworked the i18n context
(UiI18n gained plural(key,count,params); desktop menu items moved from
label to labelKey resolved via i18n; DESKTOP_NATIVE_ENGLISH spread into
the dict). Reconcile every drifted overlay file (three-way merge, taking
upstream + re-applying amicode customizations):

- language.tsx: take upstream (plural/layoutLocale/direction); keep our
  'en' default-locale (only en.ts is branded)
- app.tsx: UiI18nBridge passes layoutLocale + plural through
- en.ts: import + spread DESKTOP_NATIVE_ENGLISH; override the app-name
  desktop.menu/recovery strings to 'Amicode'
- desktop-menu.ts: take upstream labelKey shape; keep our action-only zoom
  (no native role, macOS accelerators)
- windows-app-menu.tsx: take upstream labelKey resolution; keep rounded-sm
  + 'Amicode' group label
- helpers.ts: take upstream compareSessionTime; keep our sessionListDirectories
- prompt-input.tsx / image-attachments.tsx / v2/prompt-input: fileLabel prop
  + typeLabel 3-arg
- message-part.tsx: AnimatedCountList {key,count} shape + typeLabel 3-arg
- tool-count-label.tsx: take upstream plural-key AnimatedCountLabel; keep
  splitCountLabel export for our added test
- markdown-shiki.worker.ts: DELETE — orphaned by the upstream marked
  pipeline rewrite (nothing imports it; CM6 theme sync via shiki-theme-state
  is a separate, intact path)

Verified: overlay typecheck clean across all 7 packages, engine typecheck
gate clean, build:binary + build:app green, drift-gate PASS.
@jack-champagne
jack-champagne force-pushed the chore/overlay-sync-v1.18.30 branch from 078e157 to 0b34662 Compare September 24, 2026 04:48
The rebase onto main surfaced the amicode#987 guard test, which pins the
exact shape of the tool-count-label overlay twin: a self-contained,
undefined-safe splitCountLabel(text?: string) (the guard extracts and
evals it verbatim). My earlier version delegated to upstream's internal
split(), which the guard's evalHelpers could not resolve (ReferenceError:
split is not defined) and which lacked the 'const value = text ?? ""'
guard string.

Inline the guarded split directly into splitCountLabel, drop the internal
split(), and point AnimatedCountLabel's memos at splitCountLabel — keeping
upstream v1.18.30's plural-key API. Guard passes 6/6; the undefined-t memo
chain never throws (the production hub-panel crash path).
The OpenAI Codex plugin's models() filter (runs when OAuth'd) dropped
any model whose id lacked a dotted minor version: the regex was
/^gpt-(\d+\.\d+)/, so gpt-5.6 matched but gpt-6-astra/sol/luna (no
.minor) were filtered out — invisible in the native openai picker while
Bedrock/GCP (which bypass this filter) showed them.

Our overlay codex.ts was authored on v1.18.29 and shadowed the base:
v1.18.30 already fixed the regex to /^gpt-(\d+)(?:\.(\d+))?/ with a
major>5 || (major===5 && minor>4) gate. Took the v1.18.30 base version
(which also carries the compute-residency header path) and re-applied our
one customization: the EADDRINUSE OAuth-port friendly error, rebranded to
Amicode.

Verified: the built binary now lists openai/gpt-6-astra|sol|luna (+ -fast
mode variants); engine + overlay typecheck gates green.
… alpha

The v1.18.30 overlay sync (base bump + provider/model reconciliation +
CI repairs + i18n drift + gpt-6 codex-filter fix) ships as 0.3.7. The
release version guard requires the tag base (v0.3.7-alpha.1) to equal
this manifest version.
