- io_uring is a must; epoll approach discarded (developer decision)
- plan superseded by shard-fiber-arc plan of record; banner + row in
plan/discarded.md; file kept as idea reference
- three live pointers repointed: status language-track row 8,
principles enforced-by, story 08 note

- code-verified ready: arc stages 1+2 merged to master; stage 3
concrete in plan (tasks 7-8); rt.db set on primary only
(main.c), worker_late_init memsets rt — WO_T_DB hole real
- 22/23/24/31 stay in refine/: open forks, no bench harness,
no crypto builtins, chain-blocked
- links fixed both directions; board doctrine names hold/ bucket

- 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.

- 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

- 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)

- 9e durability/throughput/scale: the measurement backbone -- run the
employee program, restart to prove persistence, benchmark read/write
through compiled .wo, ~1M-row mixed load with throughput floor + p99
ceiling + flat RSS; the gate every optimization signs (before/after
delta required, no measured delta = not accepted)
- 9f io_uring group-commit: replace fsync-per-commit with batched
io_uring durability overlapped on shard threads; same ack-after-
durable contract, crash battery unchanged, automatic fsync fallback
on kernels without it; deliberately LAST (needs 8's threads to
overlap and 9e's baseline to beat)
- wired the existing levers into the arc: iteration 8 (thread-per-core)
= "optimize multithreading", 7b (mark-sweep) = "implement GC" --
each now gated by re-running 9e and recording the delta
- explicit sequence recorded in 9e: 9b lands -> 9e baseline -> 7b
re-bench -> 8 re-bench -> 9f re-bench
- roadmap + board rows for 9e/9f; four forks each for the specs
(load generator, absolute vs relative budgets, what "1M" means,
durable vs RAM headline; ring model, liburing vs raw, batch
boundary, fallback testing)
