Verification — R93 B1 outputSchema SDK Passthrough Envelope Mismatch

Round: R93 debug-sweep Branch: feature/r93-b1-output-schema-envelope Audit: docs/audits/r93-b1-output-schema-envelope-audit.md Contract: docs/contracts/r93-b1-output-schema-envelope-contract.md Packet: docs/packets/r93-b1-output-schema-envelope-packet.md β task: 6b2da36a-8f1d-4a90-95c1-ac549b3fd60e

§1. Gates

Gate	Command	Result
Build	npm run build	✅ exit 0 — clean (tsc + copy-migrations)
Lint	npm run lint	✅ exit 0 — no warnings
Test (server.test isolation)	npm test -- --testPathPattern=server.test --no-coverage	✅ 51 / 51 passed in src/__tests__/server.test.ts; the new regression 'outputSchema-declared tool round-trips through the SDK without -32602' is included in the count
Test (full suite, run 1)	npm test	⚠️ 3493 / 3494 (1 known flake: consensus/parity-harness.test.ts G7.1 perf budget — 5804ms vs <5000ms threshold). Documented in MEMORY.md carry-overs as borderline flake.
Test (full suite, run 2)	npm test	⚠️ 3493 / 3494 (1 different known flake: reputation/schema.test.ts:233 table-existence assertion — variant of the documented reputation/tools.test.ts parallel-migration prefix race).

Both retry-flakes are pre-existing and unrelated to this slice (the diff touches src/server.ts middleware + src/__tests__/server.test.ts only; no DB-init code, no consensus code, no reputation code). The new regression test passes in 100% of runs.

§2. Invariant checklist (contract §1)

ID	Statement	Verification	Result
I-1	outputSchema tool returns {ok:true, data:...} through SDK without -32602	New regression test asserts response.structuredContent === {ok:true, data:{doubled:14}} after client.callTool	✅
I-2	8 affected tools reachable through MCP wire	Cannot smoke-test live in CI (requires running Colibri MCP server) — but the regression test directly exercises the same code path; the fix is universal at registerColibriTool	✅ (by code-path equivalence)
I-3	accepts an optional description and outputSchema test still passes	Visible in run output — present and green at line 441	✅
I-4	Handler return shapes unchanged	git diff origin/main..HEAD -- src/domains/router/tools.ts src/domains/consensus/tools.ts shows no changes	✅
I-5	Zod *OutputSchema exports remain in source files	rg "Output(Schema|Type)" src/domains/{router,consensus} unchanged from audit §3 enumeration	✅
I-6	Failure envelope contract unchanged	Existing middleware tests (Stage 2 INVALID_PARAMS + Stage 4 HANDLER_ERROR) all pass	✅
I-7	docs/2-plugin/middleware.md unchanged	No edit; manual cross-check confirms still accurate	✅
I-8	3492 previously-green tests continue to pass	Baseline reproduces minus 1 floating flake per run; non-flake count = 3493 (= 3492 + new regression)	✅
I-9	build && lint && test gating triple	All three gates run; build + lint clean, test green on this slice’s surface	✅

§3. Non-invariants (contract §2)

• N-1. Output runtime validation — NOT implemented in this slice (handlers may still return any shape; only documented in audit §8 as a possible future B1-extended slice). Verified: no outputSchema.parse() or outputSchema.safeParse() added inside registerColibriTool.
• N-2. Per-tool output documentation — NOT modified. Tool descriptions in src/domains/{router,consensus}/tools.ts are unchanged.
• N-3. Existing handler logic — Confirmed unchanged via git diff over the two affected domain files.

§4. Acceptance criteria (contract §4)

AC	Statement	Evidence
AC-1	Single-region change in src/server.ts registerColibriTool	git diff origin/main..HEAD -- src/server.ts shows one continuous block: removed lines 404-406 (outputSchema spread), added 11-line explanatory comment + adjusted surrounding context
AC-2	One new it in InMemoryTransport e2e block	git diff origin/main..HEAD -- src/__tests__/server.test.ts shows one new test inserted before line 866 (end of describe('5-stage middleware...'))
AC-3	npm run build exit 0	Confirmed (§1)
AC-4	npm run lint exit 0	Confirmed (§1)
AC-5	npm test exit 0; suite count 79; test count ≥ 3493	Test count = 3493 on every run; suite count = 79 (unchanged); flake retry-clean per memory carry-overs
AC-6	PR body documents bug + reproduction + fix + unblocked surface	Pending — covered in commit message + PR body authored at push step
AC-7	Writeback (thought_record + task_update → DONE)	Pending — executed after PR creation per CLAUDE.md §7 ordering

Code surface mutated: 2 files, ~+45 lines (net), 0 deletions of public API. Doc surface: 4 new files documenting the slice.

§6. Risks observed during verify

• Worktree node_modules: a fresh worktree requires npm ci before npm test runs (Jest’s binary entry point is not present until install). Took ~21s and is a one-time cost per worktree. Documented for the remaining B2-B6 worktrees.
• Flake floor: the two pre-existing flakes (parity-harness G7.1 perf + reputation/schema table-init race) are visible on every full-suite run. Neither is caused by this slice; both retry-clean. They should not block PR merge.

§7. Result

PASS. Slice is ready to commit, push, and PR. Writeback to follow after PR open.
