Summary

Test-hardening findings left on merged pull requests, where the claim held on the current tree. Tests and test helpers only; there is no change under src/.

Area Thread What the suite now does
Acceptance gate, cell 8 #1849 (comment) cell 8 also requires the server's own ceiling-rejection log to hold a generation request
adjust-body-after-400 and the built dist/ #1350 (comment) the suite asserts the build is fresh and says it needs a build; no pretest hook
Retry telemetry on the stream span #1445 (comment) the turn runs under a caller span; exactly one neurolink.stream span must carry the count and its parent must be that span
Turn time limit finish reason #1677 (comment) the provider span's finish reason must be exactly other
Autoresearch TaskManager cases #1334 (comment) the cases drive nl.tasks.create/run in a built-only child process against a recorded response (no credentials needed); the success-or-error status gate is kept; the lint exception comment is narrowed
Avatar and music unit suite comments #1354 (comment) comment change only
OpenAI-compatible and LiteLLM stream cases #1334 (comment) the OpenAI-compatible and LiteLLM stream cases moved to provider-wiring and run through NeuroLink.stream
setup --provider <id> routing #1337 (comment) a CLI table over setup --provider <id> --check for seven providers, each told apart by its own banner
OpenRouter setup instructions #1337 (comment) a CLI case checks the banner, env var, key URL from the descriptor and enum-backed model ids, and that the stale ids are gone. The model ids themselves were already changed on the base.
Redirecting image URLs #1497 (comment) a redirecting image URL through NeuroLink.generate on the native undici branch and on the forced-mismatch branch, with the branch reported
Tools together with a JSON schema on the OpenAI wire #1691 (comment) an offline wire case proves tools and a response_format JSON schema arrive together; the live json-e2e OpenAI and Azure cells pass tools explicitly and assert it
Post-emission failure in the loop engine #1362 (comment) loop-engine asserts the original error object surfaces
Model-not-found fallback #1334 (comment) model-not-found-retryable requires result.provider to be the second member
Catalog alias loop #1357 (review finding) the loop clears the catalog credentials before each row
Assertion messages in the descriptors suite #1337 (comment) and #1337 (comment) (one defect raised twice) the messages no longer match the harness rule that turns a failure into a skip
A throwing provider factory #1335 (comment) ProviderFactory wraps it as "Failed to create provider ..." with the original as the cause
Bedrock handle after a failed dispatch #1718 (comment) a direct Bedrock provider handle must report enhancedWithTools false after a failed dispatch

Proofs

Each new assertion that observes behaviour was shown to fail when the shipped code or the helper it drives was changed by one line, and to pass again once the line was restored; every restore was checked by file hash and a clean tree.

  • Acceptance-gate cell 8: removing the server's rejection log capture fails the cell.
  • Stale build: a touched source file makes adjust-body-after-400 fail with the stale-build message; a fresh build passes.
  • Caller span: a decoy span carrying the same attribute fails the case.
  • Turn time limit: reporting stop instead of other fails the case.
  • Autoresearch child: the offline run reports success, a dead-endpoint run reports an error status and exits 0, an out-of-contract status makes the child exit non-zero with the gate message, and with the gate removed the same mutant survives (so the gate is what catches it).
  • Relocated and added wiring cases: the Bedrock tool report, the OpenAI tools-with-schema case, both redirect cases, the factory-failure cause, the setup routing table and the OpenRouter case each fail under their own mutation of src/.
  • loop-engine: rethrowing a wrapped error instead of the original fails the identity case.
  • Catalog alias loop: a typo in a later row's env var goes red with the credential cleanup, and stays masked without it.
  • Skip rule: the three old assertion messages are classified as expected provider errors; the three new ones are not.

provider-wiring on Node 24 takes the matching redirect branch (undici 7) and on Node 22 the mismatched one (undici 6), and each run reports which.

Limits

  • The live halves were not run: the json-e2e OpenAI and Azure cells and model-not-found-retryable need credentials, so the fallback-member check has no live proof.
  • The redirect dispatcher's matching branch is exercised only where the built-in undici is major 7; on Node 22 both redirect cases take the mismatched branch.
  • On Node 22 the provider-wiring case "Bedrock carries the caller's text on the wire across all four public surfaces" fails; the same case fails on the release copy of the suite, so it is not caused by this change.
  • The proofs are mutations of this repository's own code, not live provider behaviour, and they ran on a loaded machine.
  • docs/provider-integration/acceptance-gate.md is unchanged: its cell 8 paragraph stays true.
  • There is no generic-provider row in the setup CLI table; the generic fallback stays covered through the compiled module in provider-wiring.
  • The model ids shown by setup --provider openrouter come from the OpenRouterModels enum; their public availability was not probed.
  • The abort case's finish-reason message in anthropic-loop-characterization still interpolates the finish-reason list (existing, outside these findings).
  • test:providers-mocked was not run as a separate step; the pre-push hook and the provider-safety-net check run it.

Summary by CodeRabbit

  • Tests
    • Expanded coverage for autoresearch tasks run through the public task-management interface, including offline runs.
    • Added checks for budget-limit rejections, provider selection and error reporting, and tool handling across providers.
    • Strengthened validation of JSON-schema requests, streaming events, retry telemetry, and image downloads.
    • Added checks for provider setup instructions and command-line setup behavior.

Each change answers a review thread on an already-merged PR where the claim held on the current tree. Where behaviour is observable, the new assertion was shown to fail under a mutation of the shipped code or helper and to pass without it (Verification below).

- T4126860994-cell8-any-error (#1849): acceptance-gate cell 8 also requires the server's own ceiling-rejection log to hold a generation request, so an unrelated failure no longer passes as a ceiling rejection.
- T3803405870-f1 (#1350): adjust-body-after-400 asserts the dist is fresh and says it needs a build; no pretest hook.
- PF-T3831614092 (#1445): the retry-telemetry case runs the turn under a caller span and requires exactly one carrying neurolink.stream span whose parent is that span.
- T3982196371 (#1677): the turnTimeoutMs case asserts the provider span's finish reason is exactly "other".
- T3790263591 (#1334): autoresearch TaskManager cases drive nl.tasks.create/run on a built-only child process (recorded response without credentials) instead of importing executeAutoresearchTick; the success-or-error status gate is kept; allowlist comment narrowed.
- T3813998716-a (#1354): avatar and music unit comments no longer claim a later suite shares the process (comment only).
- T3790263593 (#1334): the openai-compatible and litellm stream cases moved from the all-src bugfixes suite to provider-wiring through NeuroLink.stream.
- T3792798221 (#1337): CLI table over setup --provider <id> --check for seven providers, each told apart by its own banner.
- T3792799057 (#1337): CLI case for the OpenRouter instructions: banner, env var, key URL from the descriptor, enum-backed model ids, stale ids absent. The model ids themselves were already changed on the base; no source change here.
- T3838077531-1 (#1497): redirecting image URL through NeuroLink.generate on the native undici branch and on the forced-mismatch branch, with the branch reported.
- T3997563302-hastools-branch (#1691): offline OpenAI wire case proving tools and a response_format json_schema arrive together; json-e2e openai/azure cells pass tools explicitly and assert it.
- T3810624363 (#1362): loop-engine asserts the original error object, not its message, surfaces from a post-emission failure.
- T3790127397-1 (#1334): model-not-found-retryable requires result.provider === member#2.
- F-alias-loop-env-leak (#1357): catalog alias loop clears catalog credentials before each row.
- T3793457235, T3793574454 (#1337, one defect raised twice): three descriptors-suite assertion messages no longer contain "API key", which turned a real failure into a skip.
- T3790457162 (#1335): ProviderFactory wraps a throwing factory as "Failed to create provider ..." with the original as cause.
- T4042243054-b (#1718): a direct Bedrock provider handle must report enhancedWithTools false after a failed dispatch.

Not done:
- docs/provider-integration/acceptance-gate.md cell 8 paragraph not changed (it stays true).
- No generic-provider row in the setup CLI table; the generic fallback stays covered by provider-wiring through the compiled module only.
- Live halves not run: json-e2e openai/azure and model-not-found-retryable need credentials, so T3790127397-1 has no live proof.
- The redirect dispatcher's matching branch is exercised only on a runtime whose built-in undici is major 7; on Node 22 both redirect cases take the mismatch branch.
- The abort case's finish-reason message in anthropic-loop-characterization still interpolates the finish-reason list (existing, outside these ids).
- Public availability of the OpenRouter model ids was not probed; they come from the OpenRouterModels enum.

Verification: build, check, lint, check:tools-tests, check:deps,
provider-structure, model-manifests and the suites these changes touch pass on
Node 24; the live json-e2e and model-not-found-retryable cells skip without
credentials. Each assertion that observes behaviour failed under a one-line
mutation of the shipped code or helper and passed once restored: acceptance-gate
cell 8, the stale-build check, the caller-span case, the turn-time-limit finish
reason, the autoresearch child's status gate, the Bedrock tool report, the
OpenAI tools-with-schema case, both redirect cases, the factory-failure cause,
the setup routing table and the OpenRouter case, the loop-engine error identity
and the catalog alias loop. provider-wiring on Node 22 takes the mismatched
redirect branch; its Bedrock "caller's text" case also fails on Node 22 with
the release copy of the suite.

📝 Walkthrough

Walkthrough

This PR updates continuous-suite tests and helpers. It adds a child-process test for the public autoresearch TaskManager path and expands assertions for provider requests, streaming, telemetry, errors, CLI setup, and acceptance-gate budget rejections.

Changes

Continuous test coverage

Layer / File(s) Summary
Public TaskManager autoresearch path
eslint.config.js, test/continuous-test-suite-autoresearch.ts, test/helpers/autoresearchTaskRunner.ts
The suite runs the public TaskManager path in a child process. The runner checks persisted task history, captures events, and supports an offline recorded response. Suite comments distinguish this path from direct ResearchWorker tests.
Provider request and streaming coverage
test/continuous-test-suite-bugfixes.ts, test/continuous-test-suite-json-e2e.ts, test/continuous-test-suite-provider-wiring.ts
Provider-wiring tests cover tool lifecycle events, LiteLLM text deltas, tools combined with JSON schemas, and redirected image downloads. JSON E2E tests check tool and schema request bodies for OpenAI and Azure. The streaming tests removed from the bugfix suite are covered in the provider-wiring suite.
Provider error and telemetry assertions
test/continuous-test-suite-anthropic-loop-characterization.ts, test/continuous-test-suite-loop-engine.ts, test/continuous-test-suite-model-not-found-retryable.ts, test/continuous-test-suite-provider-model-resolution.ts, test/continuous-test-suite-provider-wiring.ts
Assertions check Anthropic span parentage and finish reasons, loop-engine error identity, the selected provider after retry, provider-factory error causes, and enhancedWithTools after a failed tool dispatch.
Provider setup and suite isolation
test/continuous-test-suite-bugfixes.ts, test/continuous-test-suite-openai-compat-catalog.ts, test/continuous-test-suite-provider-descriptors.ts, test/continuous-test-suite-avatar-unit.ts, test/continuous-test-suite-music-unit.ts, test/continuous-test-suite-adjust-body-after-400.ts
CLI tests check provider setup routing and OpenRouter instructions. Other tests clear catalog environment variables, update provider configuration messages, document handler-registry restoration, and check distribution freshness.
Acceptance-gate budget checks
test/helpers/acceptanceGateServer.ts, test/continuous-test-suite-acceptance-gate.ts
The server records over-budget requests separately and exposes them through budgetRejections(). The suite checks that a rejected request targeted /chat/completions or /messages.

1376-1385: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Include the child stderr tail in the failure message.

When a child assertion fails, Node writes its message to stderr. The callback ignores stderr and wraps the child error in a generic message. The catch logs only the wrapper’s message, so CI may not identify the failed assertion. Append a bounded stderr tail.

Suggested fix

+        (error, output, stderr) => {
           if (error) {

-                cause: error,
-              }),

murdore added a commit that referenced this pull request Oct 5, 2026
- T3790127396-1 (#1334): give the gzip-bomb note in file-formats.ts its own comment block and rejoin the split cleanup comment. No decompression-bound assertion (accepted gap).
- T3792795326 (#1337): already-fixed by tests-core-a (#1913): table-driven built-CLI cases cover every provider branch of the setup delegate (openai in the existing check-only case, google-ai, anthropic, azure, bedrock, vertex, huggingface and mistral in the routing table, openrouter in its own case). No test added here.
- T3792797794 (#1337): new built-CLI wizard case asserts the "Current Status:" block with one configured provider.
- T3792798663 (#1337): the same case asserts the "Available Providers:" box table, its header row and all nine provider rows.
- T3806521857-a (#1354): delete the src-importing handler-registry suite, its package script, its eslint allowlist entry and its CI shard line, after porting exact enumeration (realtime-unit) and per-processor isolation (media-registry-collisions) onto dist suites.
- T3810940749 (#1351): correct the eslint allowlist comment and the model-manifests header: four modules resolve against the manifest registry and core/constants.ts derives PROVIDER_MAX_TOKENS from the manifest files directly.
- T3826207455 (#1391): correct the loop-engine header and its eslint allowlist comment: the Anthropic, Bedrock, AI Studio and Vertex clients run on runAgenticLoop; the determinism exception is kept.
- T3833305692#1 (#1446): reword the aistudio abort comment to what the assertion pins (no further request); history after an abort is not covered.

Not done:
- T3790127396-1: no decompression-bound assertion (an RSS probe flakes under load); the archive bomb fixture helpers stay.
- T3792795326: the generic-provider fallback of the delegate is still covered only through the compiled module (provider-wiring), not through the CLI.
- T3792797794: the zero-provider branch of the status block is not asserted.
- T3833305692#1: no Bedrock abort cell; history after an abort is not covered by any suite.
- T3810940749, T3826207455: no suite was moved or rewritten, only comments.

Verification: build, test:bugfixes (306), test:media-registry-collisions (12), test:realtime:unit (20), test:model-manifests (18), test:loop-engine (35), test:resolve-request-kind (16), test:harness-offline-timeout (10), test:aistudio-loop-characterization (18), test:provider-descriptors (70), test:provider-structure (7), check:test-parse, check, check:tools-tests, check:deps, lint (0 errors) all exit 0; test:file-formats exit 0 (1 passed, 66 skipped for lack of credentials, same as before); test:providers-mocked 529 passed on its second run (the first run passed 528 and failed one wall-clock case, 'DECIDE perplexity-decider: no usable Retry-After means the default backoff', whose code this change does not touch). Temporary source mutations proved the wizard, enumeration and isolation cases red on the intended assertions and the old handler-registry suite red for list truncation and shared state before it was deleted.
