shoney.arickathil 2a4c304378 docs: stories foldered by state — done/ and refine/
- 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)

Iteration 15 — dependencies: wo.toml [deps], git fetch, wo.lock

Format: product/story-iteration-template. Part of Story — one language, one runtime, one database, one binary.

Inserted 2026-08-18. LANDED the same day (branch web-framework): all acceptance criteria met — just deps-accept 8/0 (cold fetch + lock, use and /sub, offline-when-locked with the remote deleted, lock-beats-moved-tag, --update-deps, drift/transitive/collision diagnostics WO-E106/E107, dep fn main never the entry, manifest shape). The enabler for code shared between writeonce repositories — the web framework (iteration 16) is the driving consumer.

Spec exists: 2026-08-18-web-framework-design.md section A is normative for this iteration. Plan: 2026-08-18-deps-package-manager.md (5 tasks: manifest inline-table + [deps]; resolver fetch/cache/lock; multi-root discovery + module mapping + entry restriction; the just deps-accept gate over file:// remotes; docs closeout).

Goals

  • A project declares exact-rev git dependencies in wo.toml [deps] (name = { git = "...", rev = "..." }); woc fetches them (via the git binary — no network code in the compiler) into .wo-deps/<name>/ and resolves use <name> / use <name>/sub into the dep's module tree.
  • wo.lock pins resolved SHAs: builds are reproducible, a moved tag is reported rather than silently followed, and a lock-satisfied build never touches the network.
  • Honest edges: transitive [deps] refused with a diagnostic (flat-only v1), dep/local module-name collisions diagnosed, a dep's fn main ignored, pub applies across the boundary exactly as across modules.

Acceptance Criteria

  • Given an app whose [deps] names a framework in a local file:// git repo, when woc <app> runs twice, then the first run fetches + writes wo.lock, the second builds offline from .wo-deps, and the built binary runs.
  • Given the dep's tag moved after wo.lock was written, when the app builds, then the lock wins and the drift is reported; woc --update-deps refreshes it.
  • Given a dep whose own wo.toml has [deps], or a dep name colliding with a local module, when the app builds, then each is a named diagnostic, never silent misresolution.

Out Of Scope

Registries, version ranges/semver solving, transitive dependencies (the successor's first fork), private-remote auth handling beyond what ambient git config provides, vendoring commands.

Proposed Solution

Manifest parsing extends compiler/bin/main.ml's existing wo.toml reader; fetch = Sys.command over the git binary; resolution plugs the dep root into the existing directory-as-module discovery. Fixtures under tests/ use local file:// remotes so the suite stays network-free.
