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

# Iteration 4 — single binary end-to-end
|
|
|
|
> Format: `product/story-iteration-template`. Part of
|
|
> [Story — one language, one runtime, one database, one binary](../00-story.md).
|
|
|
|
## Goals
|
|
|
|
- The two halves meet: `woc` emits `.wob` images the VM's loader accepts,
|
|
a conformance corpus pins language behavior from both sides, and
|
|
`woc build` produces the story's headline artifact — one self-contained
|
|
executable.
|
|
- This is the milestone where "a new language with arithmetic and garbage
|
|
collection" is demonstrably real: source in, running binary out.
|
|
|
|
## Acceptance Criteria
|
|
|
|
- What to achieve?
|
|
- **Given** the pricing demo's logic subset,
|
|
- **when** `woc` compiles it on a developer laptop,
|
|
- **then** compilation finishes in under 100 ms and `wovm` runs the
|
|
resulting module with correct output.
|
|
- What to achieve?
|
|
- **Given** the three-kind conformance corpus (runs with expected
|
|
stdout; must-fail-compile with expected `WO-E###`; must-trap with
|
|
expected trap code),
|
|
- **when** the harness runs the full suite,
|
|
- **then** every fixture lands in its expected bucket and ASan/Valgrind
|
|
report zero errors across the suite.
|
|
- What to achieve?
|
|
- **Given** `woc build` on a sample project,
|
|
- **when** the produced binary is copied to a machine with no OCaml, no
|
|
compiler, nothing but Linux,
|
|
- **then** it runs with no arguments and behaves identically.
|
|
|
|
## Out Of Scope
|
|
|
|
- Anything beyond the milestone grammar (iteration 5 grows the surface).
|
|
- Hot reload / deployment mechanics (iteration 11 — but the self-exec
|
|
trailer this iteration ships is its foundation).
|
|
|
|
## Info
|
|
|
|
- The loader's validation battery is the executable spec: every image
|
|
`emit` produces must round-trip through it — the golden rule both
|
|
test suites enforce.
|
|
- The corpus becomes the spine every later iteration extends (lang, sys,
|
|
db, actor fixture kinds already scaffolded under `tests/corpus/`).
|
|
|
|
## Proposed Solution
|
|
|
|
- Execute the existing plan: `compiler/plan/2026-08-01-wob-emit-e2e-single-binary.md`
|
|
(emitter with ownership lowering + drop maps + vtables, corpus harness,
|
|
pricing corpus, ownership/trap corpora, gc pump e2e, `woc build` trailer,
|
|
`just oop-accept` gate over the five spec success criteria).
