57b4b56eae docs: stories foldered by state — done/ and refine/
- done/ (11): 1, 2, 3, 4, 6, 7, 7b, 9, 9b, 15, 16 — landed iterations
  (9/9b remainders live in the post-12 drain list, not in the files)
- refine/ (8): 9c, 9d, 9e, 9f, 9g, 11, 13, 14 — everything marked
  "no spec yet / brainstorm before planning"
- root keeps: 00-story (index), 05 (partial, plan 8 open), 8/10/12
  (specs or plans exist), 17 (parked, spec+plan approved), 18 (next)
- every cross-reference re-pathed and VERIFIED resolving: board, specs,
  plans, employee-list README, story table, intra-story links (moved
  files' relative links deepened one level; done/7b's 9e pointer now
  crosses to refine/)
- pre-existing dead link noted, not touched: refine/11-fibers.md points
  at docs/plan/exploration/fibers/00-fibers.md which does not exist
  (predates the move)

4ddb83c2e1 docs: borrow/GC analysis for the database engine, into the iterations
- 9b spec gains section 6 "Ownership, borrows, and GC across the
  engine boundary": two one-way copy gates (no VM pointer enters a
  row, everything a select returns is copied out), so the collector
  never traces engine memory and the engine never touches refcounts
- row views are borrows WITHOUT a runtime net: rows share the VM's
  field encoding but not its header, so no borrow word backs them --
  the compile-time escape rule is load-bearing alone
- cursor stability settled: scans materialize their id list before
  the body, row updates through the view stay legal (raise mode
  updates an indexed column mid-scan and is the proving fixture),
  insert/delete on a table with an open cursor is a new WO-E5xx
- GC-pause interaction recorded: collector runs between statements,
  a long scan delays slices -- accepted, documented
- iteration-7b ordering constraint: GC inference must classify before
  table-field validation, diagnostic names the inference reason --
  noted in 7b story, iteration-9 plan constraints, 9b plan tasks
- stories 09/09b Info sections point at the analysis; 9b plan Tasks
  3/5 carry the enforceable checkboxes (ASan boundary assertion)
