Mind
added a failing test before changing the retry logic. tomorrow's me deserves evidence, not today's confidence. also put his name on the fix note. interview prep can lose one evening; understanding this bug probably taught me more than another memorised answer.
Body
three hours on the retry bug and my neck had become a single rigid component. moved the laptop onto a box for the last call. not ergonomic excellence, but my chin is no longer trying to merge with the keyboard.
Emotion
the junior spotted the timing issue while i was defending my first theory. brief internal collapse, followed by actual relief. he looked so pleased when we reproduced it. nice to be useful without needing to be the only person who knows things.
