adevwithpurpose fb9984760c fix(open-sse): stop concurrent requests colliding on dedup hash for non-OpenAI formats
computeRequestHash() in requestDedup.ts projected the prompt content from
body.messages only. The dedup site in chatCore.ts hashes the *translated*
(target-format) request body, and non-OpenAI target formats don't carry a
messages field: Gemini-translated bodies use `contents`, Responses-API
bodies use `input`. So for those formats messages was always undefined,
every prompt hashed to the same null-backed value for a given model, and
concurrent requests with different prompts joined the same in-flight
promise -- the second caller silently received the first caller's
response verbatim (#10249).

Fix: project body.messages ?? body.contents ?? body.input ?? null instead
of only body.messages, keeping the rest of the canonical hash projection
unchanged. Genuinely identical concurrent requests still dedupe (the
intended perf behavior); different prompts under Gemini/Responses-API
target formats no longer collide.

Regression test: tests/unit/request-dedup-10249.test.ts reproduces the
two collision scenarios from the plan-file (Gemini `contents`,
Responses-API `input`), confirms the OpenAI `messages` case was already
correct, and asserts identical-request dedup keeps working. Verified
RED (byte-identical hashes 0b24fd88.../dc16d5b7... pre-fix) -> GREEN
(distinct hashes, dedup preserved) against this exact diff.

changelog.d/ — changelog fragments

A PR never edits CHANGELOG.md directly during the cycle. Instead it adds ONE new file here — its changelog entry as a fragment. Two PRs never touch the same file, so changelog merge conflicts (the "CHANGELOG-eat" cascade that forced a re-sync push + full CI re-run after every sibling merge) are structurally impossible.

Convention

Directory Aggregates under
features/ ### ✨ New Features
fixes/ ### 🐛 Bug Fixes
maintenance/ ### 📝 Maintenance
  • Filename: <PR-number>-<short-slug>.md (e.g. fixes/6700-dockerfile-better-sqlite3.md). The PR number prefix keeps aggregation order deterministic.
  • Content: the exact bullet line(s) that should land in CHANGELOG.md, starting with - . Multi-line (continuation) bullets are fine. Keep the repo's credit format: (#PR — thanks @user).
  • One fragment per PR (rarely more, e.g. a PR that both fixes and adds).

Example

changelog.d/fixes/6496-cloudflare-relay-worker-syntax.md:

- **fix(providers):** Cloudflare relay Worker deploys use Service Worker syntax with `body_part` metadata ([#6496](https://github.com/diegosouzapw/OmniRoute/pull/6496)) — thanks @SeaXen

Aggregation

The release captain (or /generate-release) folds all fragments into CHANGELOG.md and deletes them:

node scripts/release/aggregate-changelog.mjs            # write + delete fragments
node scripts/release/aggregate-changelog.mjs --dry-run  # preview only

Fragment well-formedness is enforced by npm run check:changelog-integrity (the same gate that guards against CHANGELOG-eat for legacy direct edits).
