- 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.

Story — one language, one runtime, one database, one binary
Format: fiberloom
product/story-template(tech-unit standard artifact). Sources consulted: fiberloomtech-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 where I opt in — 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, with per-class
@gcopt-in collected per shard — no global pause exists by construction. - 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
.wolibrary 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 (review in this order)
| # | Iteration | Delivers |
|---|---|---|
| 1 | Principles doc | docs/00-principles.md — the doctrine page every later slice links back to |
| 2 | VM core | wovm: .wob loader, register interpreter, arena, borrow word, @gc collector |
| 3 | Compiler front | woc: lexer → parser → typechecker → ownership pass, diagnostics |
| 4 | Single binary end-to-end | emitter + conformance corpus + woc build self-contained binary |
| 5 | Language surface | Haxe-parity adoptions: switch, records, optionals, try/catch, statics, modules… |
| 6 | Program mode + stdlib | fn main, exit codes, fs/proc/net/time/json builtins |
| 7 | log-watcher proof | the driving workload compiled and detecting silent deaths live |
| 8 | Shard-actor runtime | thread-per-core shards, per-shard heaps, ownership-move messaging |
| 9 | Database engine | class-shaped tables, typed WAL + recovery, insert/select execute |
| 10 | HTTP service layer | service blocks route to VM methods; REST parity with Stage 2 |
| 11 | Fibers | green threads on the shard scheduler: reduction-budget preemption, park on I/O |
| 12 | Blue-green deploy | two VM slots, in-runtime compile, atomic switch, resident rollback |
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. Iterations 8–11 follow.
- Future iterations, after iteration 11 (parked 2026-08-08 — recorded,
not scheduled):
- WO-W201
@gc-suggestion diagnostic refinement (self-reference-only heuristic shipped; shared-structure analysis deferred). - WO-E225 unknown-type validation broadened to
ref/multi/mapelement 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 onlymulti/map, so no ADT lands before iteration 7.
- WO-W201
- Recorded future stories, deliberately outside this one: the web framework
as a
.wolibrary over the recipe-box runtime; UI (##uiSSR + live patches); script-based destructive schema migrations; MCP/agent wrapper over the management plane.
