- `randread N R` in the sample: fill N rows, read R across the WHOLE range
- Weyl order `i*2654435761 mod n` — no RNG in the language, none needed;
both legs read the SAME key order so residency is the only variable
- `randread` driver leg: control (256 MiB, does not bind) vs over-cap
(6 MiB + swap), sizes kept modest — quick resolves it in ~5s
- gates the RATIO, not the absolutes: over-cap reads/sec belongs to the
box's swap device, the factor between two runs belongs to the engine
- reads must all resolve (hits == R) or the leg fails; a collapse measured
over unresolved reads is noise
- 133 checks, 0 failures; gate bites on a doctored collapse_x
Measured — this closes the gap the swap leg left:
- resident 1 851 166 reads/sec, p50 0us p99 1us
- over-cap 6 771 reads/sec, p50 128us p99 487us
- 273x throughput, ~480x p99, all 20 000 reads resolving in both
- so the two access patterns sit ~270x apart under identical pressure:
append-mostly insert ~1%, random read 273x
- departure is a STEP not a curve (1us -> 487us, nothing between), which
is why p99_departure_decile finds no knee — there is none
- caveat recorded, NOT inherited: this is demand-paged anonymous memory
through swap (4 KiB/fault, no readahead). `resident: keys` preads via
the page cache — should be better, but databasev2 2 task 7 must measure
its own read path. New criterion added there

- `Wide` text-heavy reference shape beside Int-only `Item`
- `growth N int|text`: per-decile RSS read from own /proc/self/status
- `growth-verify`: survivor of a crash must be a contiguous intact prefix
- four footprint legs under a rootless cgroup v2 cap, swap on/off
- `ceiling` leg: die at the cap, then replay must come back intact
- footprint read as median-of-marginals; doublings a separate metric
- 121 checks, 0 failures; footprint gated ±10%, kill-timing ±100%
Measured, and it inverted two of the iteration's own predictions:
- footprint 96.5-100 B/row Int vs 320.6-324 B/row text = 3.3x, NOT the
"order of magnitude" three docs asserted
- table storage has NO checked ceiling: SIGKILL signal 9, not a catchable
WO_T_OOM. overcommit lets malloc succeed; kernel kills on page touch
- swap is NOT latency collapse: 900k rows 148s capped-with-swap vs 150s
uncapped. Append-mostly never re-touches cold pages
- ack-after-fsync survives an OOM kill: ~40k rows, no holes, no corruption
- iteration 2's budget dependency is REMOVED not satisfied — there is no
"swap onset" to derive a fraction from
- fix: subprocess returncode -9 was labelled a "checked refusal"; 137 is
the shell spelling of the same signal

- `readiness: ready | refine` is a SECOND axis, orthogonal to status.
`ready` = the brainstorm is complete and the decisions are LOCKED (a spec
approved, or the forks explicitly confirmed). `refine` = open forks remain
and it cannot be planned yet
- `status: refine` RETIRED because it carried both meanings at once, so a held
iteration with an approved spec (language 18, 26) was indistinguishable from
one nobody had thought about. status is now purely where the WORK is:
done | in-progress | pending | hold — `pending` was already the board's own
rendering word, so nothing new was invented
- all 47 iterations classified from EVIDENCE in their own text, not by guess:
"the four forks are SETTLED" / "spec + plan approved" / "Approved spec:" for
ready; "Forks the spec must settle" / "no spec exists yet" for refine. Every
shipped iteration is ready by definition. 19 done, 5 in-progress, 15
pending, 8 hold; 27 ready, 20 refine
- two iterations moved refine -> in-progress rather than -> pending: language
31 and 34 are absorbed into 24 and work on them is literally happening, which
the board already showed as 🔄 while their frontmatter said otherwise. That
disagreement is now gone
- board legend, board-views' frontmatter contract, and two new Dataview
queries updated — the useful one being `readiness: ready AND status:
pending`, the startable set
WHAT THE NEW AXIS IMMEDIATELY SURFACED: of 15 pending iterations, exactly ONE
is startable — databasev2 4, io_uring group-commit, whose forks were confirmed
settled 2026-08-20. Everything else pending needs a brainstorm first. That was
invisible while one key carried both meanings, and it is now on the board.
Also caught by the sweep, unrelated to readiness but found by cross-checking
frontmatter against the board: SIX duplicate rows. Every iteration moved into
databasev2 was still listed in the LANGUAGE pending table under its retired id
(23, 32, 33, 20, 21, 27) as well as its new one. Stale copies removed. And two
databasev2 rows made claims the sweep contradicts — iteration 1 was billed
"startable today" while its forks are open, and 6 still called itself the
ceiling-raiser after 2 took that role.

Flagged by the developer: the iteration still described the pre-brainstorm
three-mode design behind a "superseded in part" banner while four tasks had
landed against it.
- iteration 2 rewritten around the shape as built: two keys
(`durable: true|false`, `resident: all|keys`), not a `mode:` enum with
`cold`. status refine -> in-progress
- added a task-by-task progress table with commit hashes, and split the
acceptance criteria into MET (each with how it was verified, not just that
it passed — e.g. the goldens-unchanged claim is `git diff` over golden/
being empty after a WOC_BLESS run, since blessing rewrites all of them) and
OUTSTANDING with the task that owns each
- kept the history rather than deleting it: the three-mode replacement, the
"one real rewrite" that was fiction, and the opposite half that turned out
genuinely deep. An iteration file is where that record belongs
- board row rewritten to agree; the track index's "the lever" section, its
principle-7 paragraph and its sequence rationale all still taught the dead
three-mode design
ITERATION 6 IS NOW LARGELY SUPERSEDED, and bannered as such rather than
quietly gutted. `resident: keys` is the ceiling-raiser and it lives in
iteration 2 (tasks 5c/5d). More than relocated: 6's premise — a user-space
resident working set with faulting and 5's eviction policy — was specifically
REJECTED by the spec in favour of the kernel page cache, since a pread against
a cached page is a memcpy. What may still be left is recorded honestly: revisit
only with a measurement showing the page cache insufficient. Its fork list
survives, especially "does the language surface the fault cost at the use
site", which is still open and still the largest question about what writeonce
is. The sequence rationale is amended too — it had 6 as the ceiling-raiser and
5 as a prerequisite on the critical path; neither holds.

- driving case: a 120 GB order table on a 32 GB host. Not a tuning problem;
no eviction policy fixes it. Developer accepted reconsidering the principle
- principle 7 rewritten: durability half UNCHANGED and unconditional
(WAL-logged, fsync before ack, CRC-dropped torn tail); residency half
demoted from law to per-table declaration. Old wording quoted in place so
the amendment is legible, with the reason: a doctrine a real workload
cannot satisfy gets ignored, and the failure it produced was an OOM kill
- spec: docs/superpowers/specs/2026-08-26-table-residency-design.md
One log-structured engine — the WAL already holds every row, so keep an
in-RAM id->offset map and pread rows back. No second engine, no user-space
row cache (the kernel page cache is the hot copy, which is already this
repo's stated position and why it avoids O_DIRECT)
- arithmetic that makes it work: 240M rows x 16 B of index = ~3.8 GB
resident in 32 GB. Indexes stay resident, rows do not. Buys ~2 orders of
magnitude, not infinity — stated plainly in the spec
- grammar: two optional keys, `durable: true|false` and `resident: all|index`,
both defaulting to today's behaviour, so all 28 existing @table
declarations compile untouched and no golden is reblessed
- rejected, with reasons recorded: mmap (rows are pointer-bearing —
table.c returns (uintptr_t)t as the slot word), buffer pool (the Rust-era
phase-12 design that died with that track), paged B-tree (stays rejected),
a three-valued enum, automatic spill, disk-backed-by-default
- self-review caught the budget defaulting to "none" while promising the ERP
developer a diagnostic instead of the OOM killer — contradiction fixed:
the budget defaults to a fraction of host memory, and its value comes from
databasev2 1's swap-onset measurement
- live docs that contradicted the amendment updated (subagent doctrine,
its guide, discarded.md's two rows, iteration 04's read claim, 07, 38);
dated specs/plans left as records. linkcheck 0 broken / 0 anchors

- docs/stories/databasev2/, numbered from 1. Six PENDING database iterations
moved from the language track and renumbered, keeping the old id in
`was_language_iteration:` so a search for "iteration 32" still finds it:
32 -> 3 WAL checkpoint, 23 -> 4 io_uring commit, 33 -> 7 single-file store,
27 -> 8 query grammar, 20 -> 9 cross-program, 21 -> 10 keypair auth.
Done work (9, 9b, 22) stays as v1 history; language 18 left whole
- the problem, read off the engine not guessed: rows are malloc'd slabs with
addresses stable forever, NO eviction/spill/paging anywhere in database/src,
the WAL never checkpoints so boot replays all history, and durability is one
process-global WO_DATA so no table can say it matters more than another.
An allocation failure IS a clean catchable WO_T_OOM — but swap thrash
arrives first and carries no error signal at all, which is the real hazard
- four new iterations:
1 measure the ceiling FIRST (curve not cliff; the three exits; kill -9 at
exhaustion) — every later default should follow from a number
2 `@table(mode: ram | durable | cold)` — the grammar ask. Small surface
(Ast.table_cfg gains a key, the parser already rejects unknown args), big
semantics: `durable` defaults so nothing changes silently, and the
compiler refuses a durable row holding a `ref` into a ram table
5 bounded tables + refuse/evict/back-pressure, shedding BEFORE the OS acts
6 cold tiering — mostly forks, incl. whether the language surfaces the
fault cost and whether @unique on cold is refused outright. A paged
B-tree stays rejected: if tiering needs one, reject tiering

- docs/stories/porch/ — a TRACK folder, not a status folder: status still
lives only in frontmatter. Adds `track: porch` so a query over
docs/stories/ can tell a porch 3 from a language 3
- 00-story.md carries the sequence, the dependency graph, and a table of
what the track explicitly does NOT own (binding -> 29, cache -> 18,
proxy -> 38, metrics -> 30, TLS/templates -> doctrine)
- eight iterations, each with phases, per-phase tasks, Given/When/Then
criteria, out-of-scope and the forks a spec must settle:
1 store-backed middleware (limiter + idempotency — needs nothing new,
first on purpose so the store pattern is proven cheaply)
2 randomness + cookies (phase A is language-track: a CSPRNG builtin;
`Resp.headers` being a map cannot emit two Set-Cookie lines)
3 sessions 4 CSRF 5 routing/response ergonomics (independent)
6 streaming core (the seam 7 and 8 wait on; chunked-request refusal
must survive) 7 SSE + compression 8 static + lifecycle hooks
- language iteration 39 -> status: hold, retitled superseded, with a row
mapping each of its goals to the porch iteration that took it. Kept, not
deleted: the Fiber study cites it and its randomness argument is what
this track is built on
- board gains a porch section; board-views gains porch and both-track
Dataview queries; porch README and the Fiber study §7 point at the track
- no code blocks in any story (plans carry concept and actions in words);

- docs/examples/writeonce-serve -> docs/examples/porch (git mv, history kept);
`[deps]` key and import are now `porch` / `porch/http` / `porch/router`
- name history preserved on the library README, not rewritten into dated
records: writeonce-framework -> writeonce-serve (08-25) -> porch (08-26).
Stories, specs, plans and the audit reports keep the older name by the
repo's own convention; only live docs and every path link were rewritten
- left alone deliberately: `internal/serve.wo`, `pub fn serve`, `serve_conn`,
`app.serve(...)` — those are functions, not the module name
- web-app/wo.toml comment corrected: it claimed hyphens are not identifier
characters and named a key this file never used. lexer.ml's `is_ident_cont`
DOES accept `-` (an internal dash is part of the identifier, which is why
binary minus needs spaces), so a hyphenated key would be legal too
- site now teaches the name: package card, the two-deps chapter and the
handlers-are-classes chapter say `porch`; site-accept asserted the old
/packages/serve route and caught the rename, as a gate should

- 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

- rename the two libraries: writeonce-framework -> writeonce-serve
(`use serve`), wo-html -> writeonce-view (`use view`). Names say the
ROLE now; every sample, script, gate and live doc follows
- stories/specs/plans keep the old names: they are dated records, and
both library READMEs carry a "renamed 2026-08-25" note
- serve/http/files.wo: StaticFiles { dir, max_bytes } — traversal
refused not normalised, extension content types, attachment
disposition for archives. Lifted out of the shop, which had said in
a comment that it belonged in the framework
- shop drops its private copy and mounts the framework's
- site: /dl/*path over $WO_DIST (default ./dist), 16 MiB ceiling
- /install gains supported systems — Linux x86-64, glibc >= 2.38,
not musl — read off `file` and the binaries' GLIBC_ symbol
versions, not off a wish list; plus GitHub release as primary,
/dl as mirror, and the sha256 verify step
- site-accept: 17 -> 21 checks (supported systems, gzip download with
a binary-safe probe, checksum, /dl traversal 404)
Verified on 192.168.0.165: the real 960,820-byte tarball downloads
as application/gzip and its sha256 matches the published digest.

`{{ }}` auto-escaping holes
- `{{ e }}` desugars to `esc(${e})` in parser.ml — a Call on the `esc`
in scope, so types/owner/emit/.wob/VM are untouched
- WO-E004 unterminated raw literal; WO-E005 newline inside "..." —

controller per directory, model at the root, bootstrap-only main)
- removed the filler `pad: Int` convention — verified unnecessary for
plain classes, interface dispatch, containers and actors
