The 'streaming no recognized content' branch added by #6216 marked ANY
stream that ended without content deltas as invalid — sweeping in two
regression-guarded pass-through contracts: an empty stream terminated by an
explicit 'data: [DONE]' (#3399 context-cache protection) and an incomplete
Claude lifecycle (ping only, no message_start; #3685 — stream-readiness
timeout territory, not failover). Both unit guards were red on the branch
and green on main (86/86 vs 84/86).
The branch now fires only for a truly EMPTY body (zero bytes — the Gemini
HTTP-200-empty case that motivated #6216), tracked via sawAnyBytes. New
guard: '#5976 truly EMPTY streaming body (zero bytes) -> invalid for combo
failover'. 87/87 across both files.
Also in this pre-flight batch:
- agentSkillTools-mcp: api.have upper bound 22 -> 23 (the #6186 catalog
addition updated the totals but missed this bound)
- delete tests/unit/free-provider-rankings-configured-filter.test.ts:
#6251 (server-side configuredOnly/availableOnly) superseded the #6245
client-side toggle it pinned; replacement declared in the test-masking
allowlist (tests/unit/freeProviderRankings-filters.test.ts, 11/11)
- Unit/integration tests: update hardcoded 42→43 in 7 test files
(agentSkillTools-mcp, agentSkills-catalog, agentSkills-generator,
agent-skills-content, agent-skills-discovery, listCapabilities-a2a)
to match the 43rd skill (config-codex-cli) added in the previous commit.
- Include CONFIG_SKILL_IDS in integration content test ALL_IDS so
skills/config-codex-cli/ is no longer "unexpected".
- listCapabilities.ts: change totalSkills from literal 42 to catalog.length
so it adapts to catalog growth automatically.
- computeCoverage assertions: include config.have in totalSkills check.
- CI: switch E2E artifact from upload-artifact path (ambiguous stripping)
to explicit tar archive. Fixes "Could not find a production build in
./.build/next" — the previous approach's download path was double-nested
(.build/next/next/...) due to upload-artifact LCA computation. tar -czf
stores .build/next/... relative to CWD; tar -xzf restores them verbatim.
- Also exclude .build/next/cache from the tar to keep archive lean.
- feat(translator): strip client_metadata in Responses→Chat translation
(Mistral 422 extra_forbidden fix); add regression test.
Integrated into release/v3.8.8. Applied review fixes: moved the SELECT 1 into a pingDb() db helper (no raw SQL in route, Hard Rule #5) + the 503 catch no longer leaks err.message (Hard Rule #12). Thanks @herjarsa!
