1ee7cce597 docs: retract the row-encoding rewrite — the flat record format already exists
- found during the pre-execution review of the plan, before any code
- the claim was wrong in both spec and plan: table.c's db_val_encode builds
  the IN-MEMORY slot; the FILE record is a separate encoding in wal.c and has
  been flat since iteration 9. enc_val inlines every kind recursively with no
  pointer anywhere; dec_val reads it back; a record is
  `WO_WAL_INSERT | class_id | id | <value per field>` in the
  len|crc|payload|mark frame; scan_record already preads and CRC-verifies a
  record at an arbitrary offset
- so the row encoding needs NO change, and Task 5 (a "self-contained,
  offset-based" rewrite billed as the iteration's substantive engineering) is
  DELETED, not reduced. 8 tasks -> 7, and the highest-risk task is gone
- the real difficulty is where the spec never looked: wo_wal_append_insert
  stages into a 1 MiB buffer, so a record's final offset is unknown until
  flush. Threading an accurate offset back through a buffered writer —
  correct across partial flush, failed commit and torn tail — is now Task 5's
  first two steps, with a unit test that straddles a buffer boundary and a
  case asserting no offset is published for a record that never reached disk
- dependent claims corrected: the mmap alternative's premise, the read-path
  bullet (now names scan_record/dec_val), and the self-review coverage table,
  which records the retraction rather than quietly dropping the row
- root cause worth noting: reading one layer and inferring another. Second
  time this iteration — the first was assuming WO_HEAP_MB bounded table
  storage when it bounds the VM arena
- no code written yet; linkcheck 0 broken / 0 anchors

3586650baa docs: implementation plan for databasev2 2 — table residency
- 8 tasks, 71 steps, from the 2026-08-26 table-residency spec
- deliberately contains NO code: discarded.md records "raw code in plan
  documents" as rejected, and all six preceding plans have zero fences.
  Stated in the header so it does not read as an omission. Every step
  instead names the exact file and line region plus the required behaviour
- task order is by testable deliverable, not by layer:
  1 grammar + defaults (no existing golden may move)
  2 the cross-table check — a durable ref into a volatile table is refused
  3 .wob v7: descriptor carries both properties, loader refuses the
    meaningless combination so it never reaches the engine
  4 durable:false skips the WAL at the three existing choke points in db.c;
    replay refuses on mismatch rather than resurrecting rows
  5 self-contained offset-based records — the one real rewrite, since
    table.c returns a malloc'd address as the slot word today
  6 resident:keys read path: id->offset map, pread, sequential scan;
    @unique and FK-restrict across the boundary are the correctness core
  7 the two runtime refusals — durable with no WO_DATA (silent data loss
    today), and the resident-footprint budget
  8 measure, baseline, crash battery, docs, closeout
- self-review table maps every spec section to a task. Two gaps found and
  closed: the escape hatch for an intentionally ephemeral run (a refusal
  with no way forward is worse than the loss it replaces), and persisting
  the offset map in databasev2 3's snapshot
- linkcheck 0 broken / 0 anchors

c0b0dbb846 docs: audit all markdown against the code, fix findings, flatten status folders
- README: shipped concurrency/HTTP/WebSockets sat in the roadmap as "not yet
  available"; "no package manager" contradicted [deps]; the deps example
  would not have compiled (the key IS the module name)
- runtime/README: leads with wovm, wo-rt.c demoted to a historical section;
  dropped 2 nonexistent recipes, crates/rt, @gc refcounting, 13 suites -> 18
- employee + log-watcher READMEs claimed "does not compile"; both are gates
- error catalog: +10 emitted codes incl WO-E250, the only diagnostic the
  shipped query surface raises; recorded why the sweep rotted
- language-surface: group-by parses, then the typechecker refuses it
- 00-code-review + 00-link-audit re-run; history kept, not rewritten
- 48 dead Rust-era exploration links de-linked rather than re-pointed (their
  prose names the retired plan by number); successor map -> discarded.md
- 08-project-structure: compiler/plan/ never existed; corpus has 9 dirs, 5 empty
- releasing.md: dropped a --draft step the workflow never had
- new docs/00-doc-audit.md: findings + disposition, incl one row where the
  audit was wrong and the doc it accused was right
- status folders removed: 34 stories flat, status only in frontmatter; 252
  links recomputed from resolved paths; board/board-views/structure retaught
- story 24 -> in-progress, since frontmatter is now the only truth
- new iteration 38: fs mutation verbs + net.connect, the two capability
  families no iteration owned
- new iteration 39: gofiber/fiber v3.5.0 parity study. The ledger called
  CSRF/sessions unblocked by iteration 34's HMAC, but the runtime has no
  source of randomness at all
- linkcheck skips .dev/.superpowers: 0 broken paths, 0 bad anchors

7ca8b178ea docs: plan — chat + actor lifecycle (10 tasks, 5 stages); spec approved
- stage 1 crypto (ids 85-87, RFC vectors), stage 2 lifecycle (cap +
  WO_T_ACTOR, call kinds 5/6, monitor, time.after — ids 88-90), stage
  3 framework WS (ws_accept + hijack, wsframe codec), stage 4 chat
  sample + 5-check gate, stage 5 closeout
- two spec deviations pre-disclosed: reply-type agreement rule
  (WO-E226 through actor-M erasure), monitor three-argument form
- battery-with-builds-first constraint baked in (stale-binary lesson)

dc3e5b7e5b Merge branch 'db-bench' (iteration 22 — durability/throughput baseline)
- brings time.ticks builtin (id 84), bench sample + campaign driver
  (scripts/db-bench.py), just db-bench/db-bench-quick recipes, first
  baseline recorded, story 22 to done/, postgres study cards
- conflicts resolved: board in-progress table (iteration 36 +
  framework rows kept, db-bench row now "22 landed"; dangling order
  anchor repointed); story 36 moved back to in-progress/ (dir-rename
  inference dragged it to done/ — 36 still awaits the manual pass)

4ec01c4c43 Merge branch 'concurrency-arc-stage3' (iteration 8 complete)
- brings arc stage 3: transparent DB actor (T7) + closeout (T8),
  db-actor sample + gate, board/story reorg (stories/00-status.md)
- conflicts resolved: runtime CODE-LOGIC (kept iteration 36 bitwise
  section AND stage-3 DB-actor section), board in-progress table
  (kept iteration 36 + framework rows AND db-bench row, links fixed
  for the moved board path)
- full battery fresh-built 11/11: woc-build wovm-build woc-test
  wovm-test oop-e2e deps-accept web-app log-watcher employee fibers
  db-actor (first run hit a stale pre-merge wovm — gates require
  built binaries and never rebuild; builds now run first)

3a30b4ac3b feat(db-bench): first baseline — the measurement contract (T5)
- bench/baseline.json: 74 metrics from the first full campaign;
  tolerances tuned by a two-run repeatability check (mix* 50%,
  read/query 35%, rest 15% — rationale in _config)
- gate bites: --check mode; doctored copy fails, both real runs 74/0
- headline: durable seed 4.5k/s vs ram 297k/s (23's case); reads
  O(table) at ~1.5k/s; mixread 1280 vs 21 ops/s single-vs-multi
  (the arc's price); msgrate 13.4M vs 2.45M (mutex-inbox number)

07c1f7b257 feat: arc stage 3 T7 — transparent DB actor (WO_T_DB hole closed)
- worker DB builtins marshal to shard 0: requester-side slot encode
  (VM heaps never read cross-shard), owner executes serialized in
  adopt, reply unparks via new WO_PARK_INBOX park + envelope 3/4
- engine gains thread-agnostic slot entry points (insert_slots,
  update_field_slot, val_encode/clone, wo_db_exec_req); traps and
  messages byte-identical to the local path
- main.c: engine + replay boot BEFORE shards spawn; workers assert
  rt.db/rt.wal NULL; busy shard adopts inbox once per slice
- latent stage-1 bug fixed: shared io_uring params static raced by
  lazy worker init lost park wakes (~1/20 hangs); params per-vm,
  short submit now fails loud
- new sample docs/examples/db-actor + just db-actor gate 8/0 (multi
  x3, uring/epoll forced, single byte-exact, WAL replay pair);
  ASan+TSan 6/6; full battery green

- five-property map in marker doc: atomicity/durability/recovery
  proven or held (18); concurrency control = stage 3's property;
  space reclamation RAM done (slot reuse), disk = new story 32
- story 08: three stage-3 criteria (one commit per write RPC +
  ack-after-owner-fsync, workers WAL-free + replay-before-serve,
  no torn reads under TSan corpus); arc plan stage 3 carries them
- refine/32-wal-checkpoint.md: snapshot + truncate, bounded replay,
  crash-during-checkpoint safe; four forks; after 23

d24c705860 feat: iterations 19 + 17 — Float/Bytes scalars (.wob v5), library kind + internal/
- Float full stack: literals (fraction/exponent; `0..10` still a range), f64
  opcodes 34-41, @table column, WAL bit-exact replay, json fractions in and
  shortest-round-trip out. IEEE-quiet — FDIV never traps where DIV does.
- Bytes: a wo_str with its own class id, so alloc/free/copy are shared but no
  Text builtin accepts one; len/at/slice/eq/concat, base64 both ways, json
  boundary as base64; TEXT_COPY preserves the kind.
- No implicit Int/Float mixing (WO-E201 in the typechecker, not the emitter,
  which picks the opcode from one side and would misread the other).
- One IEEE deviation: float_cmp total order (NaN last, -0.0 == +0.0) for
  indexes and order-by, keys canonicalized to match. `?Float` nil is a
  reserved quiet NaN — the zero word is +0.0, WO_NIL_SCALAR's bits are -2.0.
- Renderer prefers fixed over exponential in 1e-6..1e21: pure shortest makes
  a price of 900.0 read `9e+02`. One renderer for interp/json/float_to_text.
- Fixed en route: lexer double-counted the leading digit; is_scalar_shaped
  took Float/Bytes as Int-shaped; Bytes ownership needed a shared heap-scalar
  predicate or temps never dropped; order-by bit-compared negatives backwards.
- Iteration 17: `kind = "library"` (absent = program; bad value = WO-E109),
  entry-less check mode retiring the `--emit` workaround, Go's `internal/` as
  WO-E108 at the consumer's `use`. Driver-only; VM/.wob/GC untouched.
- Framework reorg: internal/{parse,serve}.wo; http/form.wo split out to keep
  media_type/form_values public (parse.wo had grown public surface).
- Docs: link audit (97 -> 88 broken, conflict markers resolved, 2 duplicate
  stories removed), 00-code-review verified 26/27, iterations re-sequenced.
- Also carries the pre-staged pub(read)/using/#if work from the index.
- Gates: corpus 103/0, test_wal 156/0, web-app 26/0, oop-accept ALL MET.

5521d21a84 docs: pending iterations renumbered by dependency + priority
- developer directive: pending iteration IDs now ARE the priority order;
  LANDED iterations keep historical numbers (code comments and commit
  history cite them — records, not a queue); 8/11 (the half-landed
  arc), 17 (parked, artifacts on a branch), 18 (next, artifacts named)
  also frozen
- mapping (recorded in 00-story): 19<-20 Float+Bytes, 20<-9c attach,
  21<-9d keypair, 22<-9e benchmarks, 23<-9f io_uring WAL, 24<-19 chat,
  25<-10 services, 26<-12 blue-green, 27<-9g query corpus,
  28<-14 skillhost, 29<-13 metaprogramming
- 11 story files renamed; every doc reference re-numbered (word-boundary
  sweep for the lettered 9x ids, phrase-level for numeric ones); the
  iterations table rewritten with Seq == priority and "(was N)" notes;
  story-scoped link check: zero broken
- merge-recovery folded in: the partial master merge had dropped the
  chat story, the fibers exploration note, the arc spec+plan, the
  framework-v2 plan, and the iteration-17 spec+plan — all restored from
  their branches and renumbered consistently

6 tasks, words-only: (1) framework skeleton — Req/Resp records + builders,
standalone-typechecking project; (2) HTTP/1.1 parse/serialize + keep-alive
serve loop with the try-bounded dispatch seam (400-close on malformed, 500-
survive on handler traps, fd/stop clean); (3) router with :param captures +
Handler/Middleware interfaces + App.serve; (4) web-app storefront —
@table Product/Order, auth middleware, json routes, [deps] manifest carrying
the future GitHub URL; (5) scripts/web-app-accept.sh — temp git remote from
the framework dir, file:// substitution into a temp app copy, full curl
matrix + restart persistence + SIGTERM + opt-in soak, wired as just web-app;
(6) docs closeout. Both enabling risks retired pre-plan (interface-field
dispatch probe; owned-move container fix pinned by run/container-owned-move).

- error catalog: WO-E106 (dependency fetch/shape failures, one code, message
  names dep + step) and WO-E107 (dep/local module-name collision) rows.
- README: a Dependencies subsection under the manifest docs — [deps] syntax,
  .wo-deps/wo.lock behavior, offline-when-locked, --update-deps, flat-only.

  story 15 header records the landing; 08-project-structure notes
  .wo-deps (gitignored) + wo.lock (committed); plan checkboxes all ticked.

(One self-inflicted casualty during this task, restored from git before
commit: a buggy doc-edit script truncated 08-project-structure.md; the file
was recovered intact and the intended one-liner applied by hand.)

Gates at closeout: deps-accept 8/0, woc-test 540/0, oop-e2e 87/0,
log-watcher 7/0, employee 8/0.

28485a271c docs: iteration 7b migration — amend the normative docs (Phase 4)
The spec's §8 migration table, applied:

- 00-principles.md P3: "@gc is a per-class opt-in, reference-counted" ->
  GC-ness is inferred; incremental per-shard mark-sweep in budgeted slices;
  still no global pause by construction.
- OOP spec: decision-table GC row -> inferred (hybrid rule named); §3 rule 5
  -> traced classes alias freely, which classes is inferred; §4 memory model
  -> the RC + Bacon-Rajan paragraph replaced by tracing (snapshot roots,
  Yuasa barrier, born-black, budgeted slices); header rc comment -> union'd
  sweep link; mixing rule restated for tracing.
- 00-wob-format.md: header says version 4; opcodes 27-28 -> reserved (loader
  rejects); the owned-temporary rule's @gc exclusion restated for tracing.
- 08-builtin-surface.md: the push RC_INC special case and the set(m,k,v)
  retention gap DELETED — neither exists without RC; the corpus cycle is
  collected by tracing.
- story 07b: status -> LANDED 2026-08-18 (with the historical note kept);
  board: 7b row ✅ (supersedes iteration 2's RC memory model), pending row
  removed.
- gc-cycle README: Phase 3 flipped to landed (the ring runs, is reclaimed,
  ASan-clean; the ?Node RC_DEC-on-nil trap no longer exists); the barrier
  prose corrected to the as-built design (snapshot-at-beginning + deletion
  barrier + born-black, not per-slice root re-reads).
- plan 2026-08-18: all checkboxes ticked + a completion banner recording the
  four deviations from the plan as written.

335a797479 docs: implementation plan for inferred GC + mark-sweep (iteration 7b)
Phased plan argued from the 2026-08-11 spec: Phase 1 additive inference +
--dump-gc (golden-neutral), Phase 2 demand promotion + rewire field kinds to
the inferred set (+ @gc-in-source error), Phase 3 the runtime collector swap
(header rewrite, traced list, tri-color mark + Yuasa barrier, retire RC, .wob
bump), Phase 4 doc migration. Each phase has file targets + verify commands.

531b0283c6 docs: remove stale old-runtime docs; abandon the ##ui frontend track
Analyzed the full 131-file docs tree (4 parallel classifiers) against the
shipped woc/wovm toolchain. Removed 21 stale docs, kept all intentional
history (Rust-track plans/done, the runtime/database design series cited by
current specs, syscall/postgres/assembly/c-runtime studies, discarded/
learnings). Deleted:

- old-runtime "front door": writeonce-pl.md, runtime/wo-language.md
  (pitched the Rust wo runtime -- REST/LiveView/SQL+Cypher -- as the current
  language; contradicted the new README)
- v1 design set: 02-recovery, 03-data, 04-ui, 05-datalayer,
  06-markdown-render, 07-ssl; runtime/database/05-go-sdk
- future-scope/ai-agents-content-management (unfinished old-runtime CMS)
- the ##ui/.htmlx LiveView frontend track (product decision to abandon):
  9 plan/exploration/ui/*, plan/14-mvc-ui-implementation,
  superpowers/plans/2026-08-01-ui-htmlx-live; 13d pricing-UI board row

Tree left link-clean: 46 dead links to the removed docs neutralized to plain
text or deleted as pure see-also bullets across 20 kept docs; whole-tree
link-resolving scan reports zero links to any deleted file. Removal recorded
in discarded.md; board Frontend section + project-structure tree updated.

dafc7c5cf7 docs: iteration 9 status — engine complete for single-shard; Task 6 incremental
- Task 6 note: db fixtures live in existing corpus kinds; crash battery
  proven at unit level; select fixtures wait on 9b's read surface

44c77ff5bf feat: update-point + delete engine half (iteration 9, Task 5 engine)
- wo_row_update_field: encode new value, unique re-check against a
  shadow BEFORE any mutation (violating update leaves the row
  untouched, DB_ERR_UNIQUE), index entries moved old-hash -> new-hash,
  old engine value freed; proven by test_table (unique refusal keeps
  the row, released key becomes insertable)
- WAL UPDATE record: full-row re-log, replay = replace (remove +
  re-create same id); prefix/suffix delta recorded as later
  optimization; test_wal replays insert+update to the updated state
- builtins 62 DB_UPDATE_FIELD (cid,id,field,value) and 63 DB_DELETE
  (cid,id), commit-before-ack like insert, WO_T_UNIQUE/WO_T_DB/WO_T_IO
  mapping; dispatch range 61..63; loader arities; runner mirror
- plan Task 5 marked superseded-in-part with the recorded deviation:
  the language surface (reads, queries, row views, delete statement)
  is 9b's, where the comprehension design put it -- no interim brace-
  select grammar to retire later
- gates: test_table 839/0, test_wal 102/0, 15 suites, oop-e2e 73/0

30ef8d8533 feat: insert executes (iteration 9, Task 3) -- DB_STUB retires for insert
- compiler: `insert Class { ... }` is a typed Ast.Insert in statement
  AND expression position, sharing the ctor literal's field grammar;
  typechecked with the ctor's omittable rule; result = the row id (Int)
- owner pass: the engine copies at the row API, so an insert BORROWS
  its field values -- no transfer, no E304; node is trap-capable and
  carries a live-mask drop entry like DbStub did
- emit: builtin 61 window = class-id const + one slot per DECLARED
  field in declaration order; omitted defaults emitted, omitted ?scalar
  gets WO_NIL_SCALAR, other omitted optionals the zero word; fresh
  argument values reaped after (the push/set copy semantics)
- runtime: database/src/db.c executes via the choke-point row API;
  rt.db/rt.wal opaque handles on wo_rt; WO_DATA=<dir> = replay
  <dir>/shard-0.wal at boot + commit-before-ack per statement (the
  builtin's return IS the ack until iteration 8 ticks); failed commit
  un-applies the row and traps WO_T_IO; loader validates the class-id
  slot (variable window documented in wob.h + format doc)
- the promised diff: trap/pricing-set-price-db-stub is now
  run/pricing-set-price-insert printing engine-allocated ids;
  durability smoke prints 1,2 then 3,4 across two WO_DATA runs
- old "bare insert is an Ident" unit test rewritten to the new
  contract; runner's loader mirror accepts id 61; goldens re-blessed
- gates: oop-accept ALL CRITERIA MET, oop-e2e 71/0, woc-test 566/0,
  wovm-test green, log-watcher 7/0

c3741262cb feat(database): typed WAL + boot replay (iteration 9, Task 2)
- database/src/wal.{c,h}: framed records len|crc32|payload|mark
  ("WOL1" written last -- no mark, no record), typed-row payloads
  walking the class-table kinds (nested records, containers, nil
  encodings), little-endian like the loader
- commit order verbatim from the shipped phase-D pattern: RAM apply,
  stage, ONE pwrite + ONE fdatasync for the batch, ack after -- group
  commit is everything staged riding one sync
- replay decodes straight into engine-owned values (no VM at boot)
  and re-enters rows through the choke-point row API, so Task 4's
  indexes will rebuild for free; next_id advances past replayed ids
  this shard owns (wo_row_create_raw)
- torn tail = short/CRC-fail/no-mark/zero-len: intact prefix applies,
  tear dropped whole, wo_wal_open positions AT the tear so the next
  commit overwrites it; CRC-valid-but-undecodable = corruption, loud
- wo_wal_check: offline oracle, no engine needed -- the crash
  battery's verifier
- test_wal 90/0 ASan+UBSan incl. five crash-battery rounds (fork,
  insert/commit/ack-over-pipe, SIGKILL mid-stream: zero acked-but-
  missing, zero acked-but-wrong); all runtime suites green, oop-e2e
  71/0; binding doc WAL section + CODE-LOGIC + plan Task 2 checked

936bd14bff feat(database): class-shaped row storage (iteration 9, Task 1)
- database/src/table.{c,h}: per-shard per-class slabs (256 rows,
  malloc'd, never moved -- row addresses stable for 9b's row views),
  occupancy bitmap, LIFO slot reuse, open-addressing id hash with
  tombstones (ids never 0, never reused)
- field encoding walks the same .wob class-table kinds the VM walks:
  scalars raw (WO_NIL_SCALAR passes through), Texts copied to db_text,
  owned objects flattened recursively to db_rec, containers
  element-wise; GCREF refused at encode (the GC bulkhead, defensively)
- two one-way copy gates: insert copies VM values in, read allocates
  fresh VM values out -- no VM pointer in a slab, no slab pointer in
  the VM, proven by mutating originals after insert
- id discipline: per table per shard, S+1 step N; owner = (id-1) % N;
  N-parametric, runs at N=1 until iteration 8, tested at N=3
- choke points: wo_row_insert/wo_row_remove carry the INDEX HOOK
  sites Task 4 attaches to; nothing else mutates storage
- runtime/Makefile links database/src into every wovm + test binary
- test_table 827/0 ASan+UBSan; oop-e2e 71/0; log-watcher 7/0;
  binding doc docs/plan/oop-vm/04-db-binding.md; CODE-LOGIC.md beside
  the code; plan Task 1 checked off

1749440351 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)

ebcbf460df docs: employee sample (target workload) + engine moves to database/
- docs/examples/employee: Department/Employee @table classes with
  @unique, [dept] and [dept, salary] indexes, ref/backlink pair;
  modes seed/report/staff/raise/drop per the 9b spec section 6 —
  written AHEAD of the features (sample-first, like log-watcher);
  README states it does not compile on today's toolchain and links
  the plans that compile toward it
- report mode is the GroupBy showcase: group-and-reduce projection
  {headcount, avg, min, max} ordered by avg desc, whole-query sum
  for payroll; staff proves both navigation directions + index probe;
  drop proves delete restrict (trap asserted)
- engine directory decision (user, 2026-08-15): database/ is its own
  top-level dir, statically linked into wovm — file structures updated
  in the iteration-9 plan and the 9b plan
- gap found by writing the sample: iteration 9's subset lacks a
  `delete` statement and restrict needs one — added to 9b plan Task 3
- 9b plan Task 6 notes the sample is pre-authored and authoritative

a55971d857 docs: status board at docs/00-status.md; gap-closure spec applied; recover lost doc
- Board renamed docs/plan/00-kanban.md -> docs/00-status.md and rebuilt: ▶ NEXT
  PLAN pointer (iteration 4 — emitter, corpus, `woc build`) then six buckets —
  stories, in progress, done, pending, discarded, learnings. It covered only the
  Rust runtime before, so the whole OOP track was invisible. All 16 inbound refs
  repointed; `Kanban:` banners renamed to `Status:`.
- New discarded.md (settled rejections with reasons: inheritance, `abstract`,
  Money/SKU/Float, Dynamic/cast/macro/extern, AOT-to-C, Menhir, shared engine
  state) and learnings.md (plumbed≠enforced, vacuous goldens, exit-0-wrong-
  output, malloc-path ASan trick, deferred checks that never reach the VM).
- RECOVERED docs/plan/exploration/blue-green-vm/00-vision.md — gone from disk,
  never committed (gitignored path), cited by five docs incl. principle 12.
  Root cause was broader: all seven forward-roadmap plans in
  docs/superpowers/plans/ were untracked and ignored, on one disk only. Dropped
  the docs ignore rules with a do-not-re-add note; added __pycache__/*.pyc.
- Repaired broken links across docs/, 270 -> 36: fixes a regression from the
  earlier reference/ -> .dev/reference/ move (relative paths at ../../ and
  deeper were skipped), plus depth and reorg drift. The 36 residual point at
  content that does not exist and need decisions, not paths.
- New spec docs/superpowers/specs/2026-08-10-logwatcher-gap-closure-design.md,
  applied: `and`/`or` verdict row; Part 3 gains `env` (six modules), swaps
  time.mono for iso/local, adds 22 bare core builtins; throw/time.mono/is cut
  (0 uses in the sample). Plan 8: Task 2 gains and/or, Task 5 drops throw,
  abstract+`is` task deleted, 8/9 renumber to 7/8. Plan 9 gains core builtins.
  Plan 10 gains the 307 -> 0 diagnostic gate. WO-E205 re-filed unreachable-by-
  design. types.ml header drops its false satisfaction-set claim. 00-code-
  review.md reduced to a stub — its rival Phase 1-4 roadmap retired.

49872a4b11 docs: six-bucket status board; recover lost vision doc; stop ignoring docs/
- 00-kanban.md rebuilt: ▶ NEXT PLAN pointer (iteration 4 — emitter, corpus,
  `woc build`) then six buckets — stories, in progress, done, pending,
  discarded, learnings. It tracked only the Rust runtime before, so the whole
  OOP track (wovm shipped, woc Tasks 1-8 shipped) was invisible.
- Board now records iteration 3's known gaps instead of silently owing them:
  `?T` plumbed but unenforced; E205/E201/E203/E204 dead, so structural
  interface satisfaction is unchecked.
- New discarded.md — settled rejections with reasons so they are not
  re-proposed: inheritance, `abstract` newtypes, Money/SKU/Float, Dynamic/cast/
  macro/extern, AOT-to-C, Menhir, shared engine state, external deployer.
- RECOVERED docs/plan/exploration/blue-green-vm/00-vision.md — gone from disk,
  never committed (gitignored path), cited by five docs incl. principle 12.
- Root cause was broader: all seven forward-roadmap plans in
  docs/superpowers/plans/ were untracked and ignored, on one disk only. Rules
  were half-fiction — 33 of 34 exploration files were already tracked, so they
  swallowed only *new* files.
- Dropped the docs ignore rules (exploration, oop-vm, superpowers/plans,
  examples/agent-loop, examples/mcp-think) with a do-not-re-add comment; added
  __pycache__/*.pyc. `tests/` stays ignored but warns that the next plan lands
  the corpus there.
