The first fifteen lines of IMPLEMENTATION_PLAN.md were the most misleading text
in the repository. They told an agent to work on branch feat/chart-engine, which
does not exist; to build M0 through M5 and stop for feedback, all of which
shipped days ago; and that the repo was a placeholder app with a toy /api/hello
endpoint to delete. It is the first thing anyone reads.
Replaced with what is true: the document is mostly history now, current work
starts from AGENTS.md, main deploys to production by design, and §16 onward is a
dated log that is the most useful part of the file for anyone debugging.
Also adds docs/archived/ with the convention written down, though nothing has
earned a place in it yet — feature_undo.md and mobile_enhance.md are designs not
yet built rather than dead ones. Archived documents stay tracked: gitignoring
them would delete them from the repository, which loses the history that makes
them worth keeping in the first place.
