- 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 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Story — one language, one runtime, one database, one binary
|
||
|
||
> Format: `product/story-template` (tech-unit standard artifact).
|
||
> Sources consulted: `tech-unit/framework`, `product/story-template`, `product/story-iteration-template`.
|
||
|
||
**AS** a developer building and operating my own products end to end
|
||
|
||
**I WANT** a new programming language — with arithmetic, ownership-based memory safety, and garbage collection applied automatically wherever ownership alone cannot express the shape — whose compiler, runtime, and database ship as a single never-stopping Linux binary that can update its own code in place
|
||
|
||
**TO** write an application once and run it forever: no external stack to assemble, no database server to operate, and deployments that swap code inside the running process with instant rollback.
|
||
|
||
## User Value
|
||
|
||
- One artifact is the whole system: the language's runtime owns the data,
|
||
serves the API, and carries its own source — the "which commit is prod
|
||
running?" class of questions disappears.
|
||
- Memory safety without a GC tax: Rust-shaped borrowing (single owner,
|
||
second-class borrows) checked mostly at compile time, and where ownership
|
||
cannot express the shape the compiler decides — no annotation to write, and
|
||
collection stays per-shard so no global pause exists by construction
|
||
(iteration 7b; iterations 1–7 shipped a per-class `@gc` opt-in instead).
|
||
- Updates are blue-green **inside** the runtime: propose, approve, compile
|
||
in-process, atomic switch, previous version resident for instant rollback.
|
||
- The runtime is a recipe box: once language + runtime + database exist, a
|
||
web framework arrives as a `.wo` library composing runtime capabilities —
|
||
the recorded next story.
|
||
|
||
## Background & Constraints
|
||
|
||
writeonce today is a declarative Rust-based runtime (Stage 2). This story
|
||
evolves it into an object-oriented language (`woc` OCaml compiler, `wovm` C
|
||
VM) per the approved specs: C as the runtime's basis (libc only), no
|
||
inheritance ever, mutable value semantics for borrowing, shard-per-core
|
||
concurrency with ownership-moving messages, RAM-authoritative data under a
|
||
WAL, and the blue-green VM pair for in-runtime deployment. Target OS is
|
||
Linux; kernel primitives are the framework. The Rust runtime retires only at
|
||
parity. Constraints: OCaml stdlib only, C libc only; docs live under
|
||
`docs/`; prose-only planning artifacts (no implementation code in stories or
|
||
iterations); no commits by agents — drafts go to `.dev/commit.md`.
|
||
|
||
## Iterations (rows in dependency order — `#` is an immutable ID, not a rank)
|
||
|
||
RENUMBERED 2026-08-20 (developer directive): pending iterations carry
|
||
fresh IDs in priority order; LANDED iterations keep their historical
|
||
numbers (code comments and commit history cite them — records, not a
|
||
queue). Mapping: 19←20(scalars), 20←9c, 21←9d, 22←9e, 23←9f, 24←19(chat),
|
||
25←10, 26←12, 27←9g, 28←14, 29←13; 8, 11, 17, 18 unchanged.
|
||
Re-sequenced from the edges in
|
||
[`docs/00-dependency-graph.md`](../../00-dependency-graph.md): landed
|
||
rows in landing order, then the pending rows in implementation order.
|
||
File names keep their IDs — every board, spec, and plan references
|
||
iterations by number, so numbers never renumber.

| ⏸ | 17 | [library projects + `internal/`](17-library-projects-internal.md) | **PARKED** (spec + plan approved, branch `library-internal`) — `wo.toml` kind = "library" + Go's `internal/` rule; slots anywhere after 16 on directive |
|
||
|
||
|
||
Review protocol: the developer reads one iteration, approves or amends;
|
||
the next starts only after approval. Each iteration is an unsplittable
|
||
value slice with its own acceptance criteria (Given/When/Then), out-of-scope
|
||
list, and a pointer to the plan document that already sequences its tasks.

## Notes
|
||
|
||
- Acceptance criteria live in each iteration file; this story frames the
|
||
outcome.
|
||
- **Critical path (locked 2026-08-08): compile and run log-watcher.**
|
||
Iterations 3 → 4 → 5 → 6 → 7 are the committed line; nothing off that
|
||
line lands before iteration 7's acceptance. Then 7b, then 8–12 (with 9b after the database engine).
|
||
- **Goal shifted 2026-08-20: log-watcher (iteration 7, landed 2026-08-15)
|
||
to the web framework.** Same day, refined by directive: the framework
|
||
stays a polished MICRO-framework (routing, middleware, `Req`/`Resp`) —
|
||
nothing MVC-scale — and iteration 17 (library kind + `internal/`) is
|
||
**parked** with spec + plan ready on branch `library-internal`. The
|
||
v1 slices landed 2026-08-20 (`just web-app` 21/0 after polish, auth,
|
||
form, multipart). Implementation order for everything still pending:
|
||
**18 (spec approved)** → 20/21 → 22 → 8 → 23 → 11 (+ h2c unparks) →
|
||
10 → 12 → 27 → 14 → 13 + parked drain; 17 parked, slots anywhere after
|
||
16 on directive. The iterations table above carries this order
|
||
row-by-row; edges live in
|
||
[`docs/00-dependency-graph.md`](../../00-dependency-graph.md).
|
||
- **Iteration 7b (inserted 2026-08-11)** sits after the critical path
|
||
deliberately: it delays nothing on the log-watcher line, and it must precede
|
||
iteration 8 because the collector should be settled before shards multiply.
|
||
It also closes iteration 4's one open gate clause and supersedes part of
|
||
iteration 2's memory model — neither is renumbered; both point here.
|
||
- **Future iterations, after iteration 11** (parked 2026-08-08 — recorded,
|
||
not scheduled):
|
||
- ~~WO-W201 `@gc`-suggestion diagnostic refinement~~ — **superseded by
|
||
iteration 7b**: the diagnostic is retired outright, because inference
|
||
replaces the suggestion it existed to make.
|
||
- WO-E225 unknown-type validation broadened to `ref`/`multi`/`map`
|
||
element types and method/fn signatures.
|
||
- ADT container roster adoption (Stack, Queue, Set, Tree, Graph, … —
|
||
see the roster section in
|
||
`docs/plan/compiler/nullable-types-implementation.md`); log-watcher
|
||
needs only `multi`/`map`, so no ADT lands before iteration 7.
|
||
- Recorded future stories, deliberately outside this one: the web framework
|
||
as a `.wo` library over the recipe-box runtime; UI (`##ui` SSR + live
|
||
patches); script-based destructive schema migrations; MCP/agent wrapper
|
||
over the management plane.
