One instrument, many subjects. A goal, a state file, a monitor, and a report.
Every milestone here answers the same question:
· Where am I? — a measured position, never a feeling
· What's next? — the engine owns the sequence, not a menu
· What's proven? — a milestone closes on evidence, or it stays open
Why this is a hub and not ten separate pages.
Anybody can make a tracker. The difference here is the honesty rules that every subject inherits:
an unattempted milestone is not a miss · no work observed means UNMEASURED, never a
fabricated 0% · coverage is not proficiency · and a milestone closes on evidence —
a commit, a URL, a certificate number — or it stays open.
Adding a subject = adding a file, never editing the engine.
