This is the original harness and discovery record. Account integration verification records its combination with the account corrections. The combined default command passes 200 pure tests. The earlier cloud passes below do not verify the newly added native account alarm case, whose combined cloud gate remains open.
This is a test-harness correction on top of unit 4, cherry-picked as c204d2c from 4988f00b5d3ffe53abff89f6331ff1bb8f82b6dd. The worker branch starts at root c260bc1. Application code, account policy, provider adapters, release workflows, stack wiring, manifests, and the approved migration plan are unchanged by this correction. Root owns independent review and acceptance.
Root's bunx bun@1.3.5 run scripts/cloud-test.ts account in the original worktree produced stage test-account-a0e65c16-56ec6e796e36, with 11 passes, three failures, and 203 assertions. All six account and release cases passed. Its cleanup verified zero Workers, zero Durable Object namespaces, and absent stage state and output.
The reconstruction assertion saw the original UUID 341b965d-4b52-4ba4-af62-8ac5c62be80f after an unchecked reset POST. The harness discarded the reset response and suppressed every RPC cause. Its Effect.retry retried snapshot errors but did not repeat a successful unchanged snapshot. Root later observed UUID 83662b9e-0c0d-4305-8f2e-0fa0f120cb73 with the same committed state. The original evidence cannot establish whether reset failed to reach the route or reconstruction completed later. Neither hypothesis is recorded as fact.
The alarm test decoded a 404 HTML response from POST /arm as JSON. Its resulting Unexpected '<' was a transport-status handling defect, before alarm assertions ran. The cache helper classified every POST 404 as FixtureRouteNotReady and retried four times at 200 milliseconds. It recorded neither the failing route nor the body fingerprint. The original cache failure's exact route and pre-execution status cannot be reconstructed from that log. GET snapshot readiness did not prove POST readiness.
The original worktree and its journals were read-only. Copies are retained under .cloud-tests/root-failure/ in this worker's checkout. The original log SHA-256 is 2f304253bdd91998a11c61dab1b143ee6075da959a34359ae95e93b84e4fb4e2. The run, resources, and result journal hashes are b820944c3db174a77f7206c883b319f7111bc86c9e2d36902b4146d23cff8246, d1fa8061777f12b1acf6f3a12f5f44158f86f3a6dd31bb6e01d92cf26f3dab19, and a971e4b00661d3d8b8f848f6c0efd4f3a8113dcb709a95e86ff943524a30576c.
tests/cloud/fixture-http.ts owns the fixture HTTP boundary. Foundation, cache, and account callers share status checks, JSON content-type checks, and schema decoding. Fixture responses identify execution with x-arc-cloud-fixture: v1. Diagnostics contain method, hostname and pathname, exact status and content type, Cloudflare ray, fixture marker, response length, and SHA-256. They omit query parameters, request bodies, authorization headers, and response bodies. Redirects are not followed.
A focused diagnostic deployed disposable stage test-account-15e5217e-d48e1d6441a0 and made 20 GET snapshots, 20 POST echoes, and 20 POST requests to an unknown fixture route. Known routes returned 200. The unknown route returned 404 with no content type and an empty body. The transient 404 HTML was not reproduced during this diagnostic. Its log is .cloud-tests/transport-diagnostic.log and its source is .cloud-tests/transport.test.ts. Its single diagnostic test passed and cleanup verified zero Workers and namespaces with absent state and output.
Read-only GET and no-op POST requests to the already deleted root stage's Worker URL independently returned Cloudflare's missing-Worker page. Both responses were 404, text/html; charset=UTF-8, server: cloudflare, and 19,984 bytes. The page's title was Page not found. Its SHA-256 was 2000e6b28a1517ba1268e1649cd3163326ef839492edfdba31e8959830580976. The safe metadata is retained in .cloud-tests/deleted-route-diagnostic.jsonl. These observations identify a pre-execution infrastructure response. They do not establish the original cache response's fingerprint.
Only that exact response hash, 404 status, HTML content type, Cloudflare server header, absent fixture marker, and a disposable test Worker hostname authorize readiness retry. The helper allows at most 15 retries spaced one second apart, with a 20-second total request budget. A read-only request to the deleted Worker exercised all 16 attempts and then failed. Its log is .cloud-tests/bounded-readiness-diagnostic.log. A changed Cloudflare page fails rather than broadening the classification automatically.
Other 404s, all 500s, redirects, unknown transport execution, wrong JSON content types, malformed JSON, and business-schema failures stop immediately. No test body or business assertion is retried. This helper does not wrap HTTP performed by application provider adapters.
tests/cloud/fixture-response.ts accepts only the requested native abort reason wrapped in Alchemy's RpcCallError. Unexpected causes propagate. A reset RPC that returns without aborting fails. Callers check the successful 204 acknowledgement. Cloudflare documents that abort resets the object and rejects the active execution. The pinned Alchemy adapter wraps a rejected native RPC in RpcCallError in node_modules/alchemy/src/Cloudflare/Workers/Rpc.ts.
After acknowledgement, reconstructedSnapshot observes the UUID condition, up to 21 snapshots at 100-millisecond intervals within five seconds. A snapshot error stops the poll. The UUID must change, and the original committed value, rollback counters, persisted alarm timestamp, alarm completion count, and retry count assertions remain. Polling is a bounded observation of the requested lifecycle event. It does not establish that delayed reconstruction caused the original failure.
The throughput checkpoint was to classify the captured failure, separate reached-fixture errors from the missing-Worker page, check reconstruction acknowledgement, run local regressions, then run one changed combined real-cloud account suite with independent teardown verification. No worker delegated further work. Architecture and comment-review fan-outs were omitted under the explicit no-delegation instruction.

The eight regressions cover the exact route-classification restrictions, POST replay prevention on reached-fixture and unknown edge failures, ambiguous transport loss, parse and schema failure, byte preservation, old-old-new UUID observation, bounded unchanged-UUID failure, snapshot-error propagation, and exact abort acknowledgement. They use local HTTP response values and virtual time. They do not emulate Cloudflare storage or claim real-cloud proof.
The first changed combined run, stage test-account-15e5217e-ccd040f6efe3, passed all 14 tests and 222 assertions. It captured a 404 on the first account-fixture GET /snapshot, followed by a 200 JSON response on retry. The failed response matched the observed placeholder hash, had the HTML content type, and lacked the fixture marker. The runner and cleanup both returned zero. Cleanup independently verified zero Workers, zero namespaces, and absent state and output.
Review then restored the original snapshot helpers' exact HTTP 200 requirement in the shared JSON decoder. A regression now rejects a schema-compatible 201 without retry. The final combined run verified that stricter decoder rather than relying on the earlier pass.
bunx bun@1.3.5 run scripts/cloud-test.ts account
Final stage test-account-15e5217e-e077475f24a3.
14 pass, 0 fail, 222 assertions.
Cloud tests exit 0; cleanup exit 0.
CLEANUP VERIFIED: zero matching Workers, zero DO namespaces,
no stage state/output; control backend retained.
The final run reproduced missing-Worker HTML on cache POST /clear, /read, /time, and /reconstruct, and GET /snapshot, interspersed with successful responses from the same cache Worker. Each failed response had the exact pinned hash, 404 status, HTML content type, Cloudflare server header, and no fixture marker. Subsequent bounded retries returned the expected 200 JSON or 204 with the fixture marker. This establishes pre-execution route unavailability in the matching cloud transport. It does not identify Cloudflare's internal routing cause or retroactively supply the missing metadata from root's first run.
For example, POST /clear returned placeholder ray a4b19ba0880ed4c1-IAD after cache snapshot success. The next POST /clear returned 204 with x-arc-cloud-fixture: v1. POST /reconstruct returned placeholder ray a4b19bf11fe3d4c1-IAD, then 204 with ray a4b19bf81a85d4c1-IAD and the fixture marker. The final run classified ten placeholder responses, including later account POSTs, by the same strict rule. The intentionally interrupted account setup and dispatch requests returned 500 and remained failures for their existing interrupted-operation assertions. No generic 404 or 500 was retried.
Both changed combined runs retained all original domain assertions. The lower assertion counter reflects HTTP status checks moved from repeated expect calls into the shared fail-fast boundary. JSON requires exact 200, reset explicitly requires 204, and schema decoding remains strict. Foundation UUID, rollback, persisted value, alarm timestamp, native alarm attempts and retry count checks remain. The alarm case additionally verifies reconstruction before waiting for native completion.
Every final cloud UUID poll observed a different UUID on its first successful snapshot. No delayed reconstruction was demonstrated. The helper's old-old-new and unchanged conditions are covered deterministically, and the live UUID changes still prove native reconstruction and persisted state.
The two combined runs and diagnostic deployment each retain run.json, resources.json, result.json, and console.log under .cloud-tests/<stage>/. Local check logs and the focused decision trail are under .cloud-tests/. The final console log is also .cloud-tests/account-harness-final.log. No failed result was overwritten or discarded.
Accepted harness review P2 found that the root test script selected only Turborepo workspace tests. Both pure helper test files live outside those workspaces. The cloud runner selects foundation.test.ts explicitly, so it also omits these regressions. Before this follow-up, bunx bun@1.3.5 run test reported 181 workspace passes and 580 assertions without executing either helper file.
The root test script now runs:
turbo run test && bun test ./tests/cloud/fixture-http.test.ts ./tests/cloud/fixture-response.test.ts
CI and release already call bun run test and inherit this change. The explicit file paths select only the two pure helper suites. They run once after the workspace tests, outside Turborepo caching. No root Turbo test task or recursive script is added. The separate cloud runner remains unchanged.

Both changed default-command runs printed each helper name exactly once:
tests/cloud/fixture-http.test.ts:
(pass) only the observed Cloudflare placeholder on a disposable Worker is route readiness
(pass) fixture and unrecognized edge failures stop POST without replaying a mutation or exposing its body
(pass) transport loss after a POST has unknown execution and is never replayed
(pass) successful HTTP with wrong content type, invalid JSON, or invalid business data is not retried
(pass) raw binary and schema-decoded JSON responses retain their actual values
(pass) reconstruction polls the observed UUID and preserves the new snapshot
(pass) an unchanged UUID exhausts a bounded poll and a snapshot failure stops immediately
tests/cloud/fixture-response.test.ts:
(pass) only the requested native abort receives a 204 reconstruction acknowledgement
8 pass, 0 fail, 73 expect() calls.
Full logs are local artifacts under .cloud-tests/test-discovery/, including before.log, after-forced.log, after-cached.log, install.log, check-types.log, and lint.log. Log checks confirmed 181 workspace tests and 580 assertions in each run, exactly eight unique helper names in each changed run, and no helper execution before the change. No cloud suite or deployment command ran for this wiring correction. Test assertions, helper logic, and application code are unchanged. Unit 4 remains blocked on the six separately owned account bugs and is not accepted by this evidence.
The original harness worktree is /home/angel/.t3/worktrees/arc-tools/t3-d1243984, branch t3/d1243984. Cherry-pick the harness correction after unit 4. Its original handoff required the explicit helper regression command because Turborepo did not discover these files. The discovery follow-up above adds them to the canonical root test script. Root retains independent review and rerun.
Fix Root Causes removed unchecked transport results and broad cause suppression. Model the Domain selected separate route-readiness and terminal HTTP errors. Boundary Discipline put response validation before JSON decoding. Prove It Works required the changed combined cloud run, native UUID transitions, strict persisted-state assertions, and API cleanup verification.
Root's original failures remain retained evidence. The matching cloud run establishes pre-execution route unavailability. The original reset cause and the original cache response fingerprint remain unknown. No application defect has been established by this worker. No real Twitch or Discord mutation, persistent staging deployment, production deployment, root audit edit, migration acceptance, or unit-4 acceptance is claimed.
The hardening suite routes independent account cases through paired account and provider objects under /journeys/:journey. Independent cache cases select a cache and source pair in the same way. Each case prepares its own grants, subscriptions, source data, and synthetic clock. The account fixture derives its outbound provider identity from the native named object during construction. The native routing and credential-alarm cases verify that identity after reconstruction and through correlated provider validation traffic. Missing native identity fails fixture construction.
The actual Bot has one ordered journey through operator setup, OAuth, signed challenge, ten commands on both transports, native recovery, multipart delivery, ambiguity, and signed revocation. Onboarding returns subscription evidence to the dependent steps. Independent Discord cases use distinct tenant IDs and source keys. The warm-cache scenario owns a separate resource key. Timing samples belong to their producing scenario and are written before assertions. Worker ingress must remain below three seconds. Client elapsed time is diagnostic.
Temporary controls use UUID ownership and durable retirement records. Cleanup is installed before activation. A failed or interrupted body closes its local scope and awaits child shutdown before restoration. Successful scenarios explicitly release held requests before joining their results. Cleanup retires only its own identity and confirms the preceding settings and absence of live gates. Lost release responses require confirmation by observation. Unknown or dirty cleanup fails alongside the original cause. Retirement records reject late activation, including after fixture reconstruction. Cleanup has an independent four-second release timer and five-second observation budget. Process death and a network partition can still prevent confirmation. Isolated objects contain that failure until stage teardown.
Ordinary requests remain terminal after transport loss, including account /snapshot, which calls status and updates state. Audited provider, native-account, attribution, tenant, cache, source-observation, and control-state reads may retry only explicit transient network codes. Each read has at most three wire attempts. Polling, retries, response bodies, decoding, and backoff share one monotonic budget. The exact disposable Worker placeholder fingerprint remains the only generic non-execution retry exception. No HTTP status class grants permission to replay a mutation.
bun run test includes the local HTTP, control lifetime, protocol, routing, and timing proofs. fixture-journey.test.ts injects acquisition loss, parent interruption, assertion failure, simultaneous cleanup failure, delayed activation, duplicate controls, reconstruction, and failed cleanup observation. fixture-http.test.ts checks retry caps, cancellation, mutation non-replay, safe cause rendering, and actual console and file journals with synthetic secret canaries. These local proofs do not establish native Cloudflare behavior.
CI retains native-alarm-attribution.jsonl, fixture-http-*.jsonl, and journeys/*.jsonl alongside the stage, resource, result, and alarm journals. Native observation has a 45-second budget and a separate bounded final evidence collection within the existing 90-second case. The completed-run causal verifier, native transaction rollback, signed protocols, immutable deadlines, replay suppression, and exact delivery counts remain acceptance requirements. The coordinator owns native cloud runs and final stage cleanup verification.
