"SpaceX" no longer colors half of the compound brand "SpaceXAI" (and block "xAI" via overlap). Needles bordered by unicode letters are skipped; digits/punctuation still count as boundaries so GPT still matches in GPT-5 and qwen in Qwen3. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
User-visible labels only: homepage heading, prefs panel, admin panel, system stats, about/changelog copy, Telegram digest button, email subject. Internal tldr identifiers unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Appended to the score, translate, and TL;DR chains after all native ids so an unproven id cannot consume fallback budget. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Annotate isLetter return type; check boundaries against lowerTitle so offsets match the indexOf coordinates (unicode lowercasing can change length). Collapse RunsList lang ternary to a constant label. Skipped: centralizing wrangler.toml model chains — per-task orderings are intentional and documented inline. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- global per-IP RateLimit-Limit/Remaining/Reset headers on every response - 429 responses carry Retry-After (both global and llm/generate limiters) - GET /openapi.json serves an OpenAPI 3.1 doc: unique operationIds, typed schemas, bearer + oauth2 securitySchemes with read:profile/chat scopes matching /.well-known/oauth-protected-resource - static mirror at apps/home/public/openapi.json Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- remove SPA fallback so unknown URLs serve 404.html with HTTP 404 (agent-friendly body pointing at llms.txt, sitemap, api-catalog) - /mcp now 308-redirects to https://mcp.duyet.net/mcp, preserving POST bodies for JSON-RPC clients - markdown/HTML negotiation responses send Vary: Accept, Accept-Encoding - same-origin /api/* suffix proxy to api.duyet.net with strict allowlist, CORS preflight, and 502 on upstream failure - prerender /developers /contact /privacy and the three /p pages so deep links survive without the SPA fallback Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- /developers: API table, auth + scopes, rate limits, MCP connect, machine-readable file index, curl quickstart - /contact and /privacy trust pages (500+ chars each) - homepage JSON-LD (WebSite, Person, Organization with contactPoint and PostalAddress) plus a developer-resources section linking /developers, /openapi.json, MCP, /llms.txt - canonical URLs on all routes lacking one; NotFound links agent indexes - sitemap + llms.txt: when-to-use, developer resources, contact & legal sections - server-card.json corrected: endpoint mcp.duyet.net/mcp, version 0.2.1 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- middleware: Vary on HTML and markdown branches - api proxy: allowlist, auth forwarding, CORS preflight, 502 path - redirects/routes/404 static-file contract tests Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The PR changes production routing and adds a same-origin API proxy, but the current implementation can drop JSON request metadata and rate-limit guidance, emit invalid CORS headers, mishandle compressed HTML, advertise unsupported API paths, and 404 non-prerendered routes. These issues can break API calls, browser clients, page delivery, or published links, so merge should wait for fixes. Suggested reviewers: Poem

**issue (broader_impact):** The same-origin API proxy discards all upstream response headers except Content-Type and Access-Control-Allow-Origin, so proxied responses do not expose the RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, or Retry-After headers that the API now promises on every response. Clients using `/api/*` therefore cannot apply the documented rate-limit behavior.
**Triggers:** When a client calls an endpoint through the same-origin `/api/*` mirror, especially after receiving a 429.
**Suggested fix:** Copy the upstream headers needed by the public contract, at minimum the RateLimit-* and Retry-After headers, while retaining the CORS headers.
```suggestion
const responseHeaders = new Headers(upstream.headers);
responseHeaders.set(
"Content-Type",
responseHeaders.get("Content-Type") ?? "application/json",
);
responseHeaders.set("Access-Control-Allow-Origin", "*");
return new Response(upstream.body, {
status: upstream.status,
headers: responseHeaders,
```
</issue_to_address>Sourcery assessment
Needs a human reviewer. 1 finding to address first, and the new production API proxy and rate-limit middleware change how authenticated requests are routed and admitted; a mistake could forward credentials incorrectly, expose a protected operation, or allow excessive upstream/LLM requests. Reverting would stop the behavior, but any requests, resource usage, or data exposure that occurred before the revert would not be undone.

Inline comments:
In `@apps/api/src/lib/openapi.ts`:
- Around line 9-15: Replace the Schema object type alias with an interface,
rename the Operation interface to ResponseObject to match the OpenAPI model, and
update jsonResponse, okResponse, and tooManyRequestsResponse return types plus
all references to use ResponseObject.
- Around line 362-401: Replace the duplicated inline response schemas in the
affected operations with $ref references to the declared ServiceInfo, Health,
AiPercentageCurrent, and Error component schemas. Update the corresponding
response entries near the existing service-info, AI-percentage, health, and
error usages, following the existing InsightsOverview reference pattern; leave
the component declarations unchanged.
- Around line 4-6: Add a consistency check that compares the generated
openApiDocument with apps/home/public/openapi.json, normalizing JSON formatting
as needed so equivalent documents pass. Integrate it into the existing test or
build validation flow and fail with a clear message when the static mirror
differs.
- Around line 601-604: Update the OpenAPI server configuration around the
servers definition so the same-origin mirror supports the meta paths “/” and
“/openapi.json” without breaking the existing API and “/health” resolution,
using proxy routes or path-level server overrides. Keep the external server
behavior unchanged and synchronize the generated specification in the public
openapi.json artifact.
In `@apps/api/src/lib/rate-limit.ts`:
- Line 72: Annotate the parameters of secondsUntil in
apps/api/src/lib/rate-limit.ts:72 with number types, and type the Hono callback
parameters in apps/api/src/index.ts:45 and :94 using Context and Next as
appropriate. The site in apps/api/src/lib/rate-limit.test.ts:116 requires no
direct change; it is covered by the function signature update.
In `@apps/home/__tests__/jsonld.test.ts`:
- Around line 24-32: Update the test for personJsonLd so it compares
person.sameAs against the complete expected profile URL array, rather than only
validating that each entry uses https://. Preserve the existing Person and name
assertions.
In `@apps/home/__tests__/middleware.test.ts`:
- Around line 60-74: Add a test alongside the existing “falls back to HTML when
llms.txt is unavailable” case that makes the stubbed fetch reject, invokes
onRequest with the same markdown request and HTML next handler, and asserts the
middleware returns the HTML response while exercising its rejection catch path.
In `@apps/home/__tests__/pages-config.test.ts`:
- Around line 39-44: Update the test around routes.include to assert that it
exactly equals the expected routes "/", "/index.html", and "/api/*", rather than
merely containing each entry. Preserve the version assertion and ensure any
additional route such as "/*" causes the test to fail.
- Around line 11-13: Update the redirects assertion in the “no longer serves the
SPA fallback” test to detect the fallback using a whitespace-tolerant regular
expression rather than exact string matching, while preserving the expectation
that any such fallback is rejected.
In `@apps/home/functions/_middleware.ts`:
- Around line 83-90: Update the response reconstruction in the middleware around
rewriteHydrationRetryHtml so both content-encoding and content-length are
removed from headers before either return path, including when patched === text.
Preserve the existing status and body behavior while ensuring all reconstructed
responses use the sanitized headers.
In `@apps/home/functions/api/`[[route]].ts:
- Around line 65-71: Update the response construction in the route handler to
preserve upstream RateLimit, RateLimit-Policy, and Retry-After headers, and
expose them via Access-Control-Expose-Headers alongside the existing CORS
header. Add coverage for an upstream 429 response that verifies these headers
are forwarded and accessible.
- Around line 55-63: Update the request header setup in the route handler to
forward the inbound Content-Type header for POST requests when present, while
preserving the existing Authorization forwarding. Add a corresponding assertion
in the API proxy test to verify the upstream request receives the Content-Type
header.
In `@apps/home/public/_headers`:
- Around line 63-68: Remove the duplicate Access-Control-Allow-Origin
declaration between the explicit /.well-known/ rules and the /.well-known/*
wildcard rule, retaining a single effective header for each discovery path so
Cloudflare Pages emits only one CORS value.
In `@apps/home/public/_routes.json`:
- Line 3: Update the routing configuration around the include list to exclude
/api/nini from Pages Functions, preserving the existing /api/* inclusion and
ensuring requests to /api/nini bypass the catch-all function.
In `@apps/home/public/openapi.json`:
- Around line 586-634: Replace the inline response object schemas with
references to the existing component schemas, using ServiceInfo for the shown
200 response, Health at its corresponding definition, and Error for every inline
error-string response; preserve each operation’s response structure while
eliminating duplicated schema definitions.
In `@apps/home/src/components/NotFound.tsx`:
- Around line 25-33: In NotFound, hoist the link definitions into a module-level
typed constant using an interface for each item’s shape, then map over that
constant so the list is not recreated on render and the callback parameter is
explicitly typed.
In `@apps/home/src/lib/jsonld.ts`:
- Around line 3-10: Define interfaces for the JSON-LD object shapes and annotate
the return types of websiteJsonLd, personJsonLd, and organizationJsonLd with the
corresponding interfaces, preserving their existing returned fields and values.
In `@apps/home/src/routes/contact.tsx`:
- Around line 12-23: Wrap every listed external URL with addUtmParams() to
preserve UTM attribution: update GitHub, X, and LinkedIn links in
apps/home/src/routes/contact.tsx lines 12-23; the MCP link in
apps/home/src/routes/contact.tsx lines 109-111; the API link in
apps/home/src/routes/developers.tsx lines 86-88; the MCP link in
apps/home/src/routes/developers.tsx lines 209-211; and the MCP link in
apps/home/src/routes/index.tsx lines 252-259.
- Around line 27-42: In apps/home/src/routes/contact.tsx lines 27-42, add
explicit return annotations to the route head callback, ContactPage, CodeBlock,
and Section while retaining existing parameter annotations; in
apps/home/src/routes/developers.tsx lines 37-60, annotate head, DevelopersPage,
CodeBlock, and Section; in apps/home/src/routes/privacy.tsx lines 7-39, annotate
head, PrivacyPage, CodeBlock, and Section. Use the appropriate existing route
metadata and JSX return types without changing behavior.
In `@apps/news/src/lib/highlight.ts`:
- Around line 13-15: Update highlightTitle boundary checks to inspect the full
Unicode code points immediately before and after the matched range rather than
UTF-16 code units, reusing isLetter for both boundaries. Add regression tests
covering GPT preceded by and followed by the supplementary-plane letter 𐐀,
ensuring neither case is highlighted.
In `@apps/news/worker/__tests__/notify.test.ts`:
- Line 156: Update the test case that builds the Read and AI;DR buttons to
assert both rendered button labels as well as their UTM-tracked URLs, including
the renamed AI;DR label.

Declare Schema as an interface and rename Operation.
The coding guidelines require interfaces for object shape definitions. Schema is a type alias.
Operation models an OpenAPI Response Object. Every use site assigns it to a response value, for example line 440 and line 553. The current name conflicts with the OpenAPI Operation Object.
♻️ Proposed refactor
-type Schema = Record<string, unknown>;
+interface Schema {
+ [key: string]: unknown;
+}
-interface Operation {
+interface ResponseObject {
content?: Record<string, unknown>;
description: string;
headers?: Record<string, unknown>;
}Update the return types of jsonResponse, okResponse, and tooManyRequestsResponse to ResponseObject.
As per coding guidelines: "Use interfaces instead of type aliases for object shape definitions".

Reference the declared component schemas instead of inlining the same shapes.
ServiceInfo, Health, AiPercentageCurrent, and Error are declared here but never referenced. The operations inline the identical objects: line 440 inlines serviceInfoSchema, lines 470-472 inline aiPercentageCurrentSchema, line 578 inlines healthSchema, and lines 474, 475, and 501 call errorSchema(). The document then carries two copies of each shape, and the copies can drift because this file is maintained by hand.
Use $ref at the operation level, as done for InsightsOverview at line 516.

Fix the same-origin server for the meta paths. https://duyet.net/api correctly resolves the API paths and /health, but / and /openapi.json resolve to unsupported proxy routes. Add proxy routes or path-level server overrides, then update apps/home/public/openapi.json.

Make the boundary check code-point aware.
lowerTitle[idx - 1] and lowerTitle[end] return UTF-16 code units. A supplementary-plane letter such as 𐐀 therefore makes isLetter return false. highlightTitle can then highlight GPT in 𐐀GPT or GPT𐐀. Inspect adjacent code points at lines 119-121 and add regression tests for both cases.

Assert the renamed Telegram button label.
The test name now states that the markup contains AI;DR, but the assertions check only URLs. A label regression would still pass. Assert both button texts.
