The documentation is part of the deliverable (spec 11.5/11.7/11.9), so it has to describe what the code does, not what was intended. Adds docs/documentation-plan.md: the package inventory against the spec, the per-claim sources of truth in the tree, the results of a first cross-check pass (11 findings, most notably the missing "operations" section required by spec 11.7, the absent env-var reference, .env.example's dangling link to a README "Rate limiting" section, and the unwritten "tar while stopped" backup path from spec 9), and tasks D1-D7 gating the next release tag. progress.md points at it so it survives a context reset.
