- Board renamed docs/plan/00-kanban.md -> docs/00-status.md and rebuilt: ▶ NEXT PLAN pointer (iteration 4 — emitter, corpus, `woc build`) then six buckets — stories, in progress, done, pending, discarded, learnings. It covered only the Rust runtime before, so the whole OOP track was invisible. All 16 inbound refs repointed; `Kanban:` banners renamed to `Status:`. - New discarded.md (settled rejections with reasons: inheritance, `abstract`, Money/SKU/Float, Dynamic/cast/macro/extern, AOT-to-C, Menhir, shared engine state) and learnings.md (plumbed≠enforced, vacuous goldens, exit-0-wrong- output, malloc-path ASan trick, deferred checks that never reach the VM). - 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. Dropped the docs ignore rules with a do-not-re-add note; added __pycache__/*.pyc. - Repaired broken links across docs/, 270 -> 36: fixes a regression from the earlier reference/ -> .dev/reference/ move (relative paths at ../../ and deeper were skipped), plus depth and reorg drift. The 36 residual point at content that does not exist and need decisions, not paths. - New spec docs/superpowers/specs/2026-08-10-logwatcher-gap-closure-design.md, applied: `and`/`or` verdict row; Part 3 gains `env` (six modules), swaps time.mono for iso/local, adds 22 bare core builtins; throw/time.mono/is cut (0 uses in the sample). Plan 8: Task 2 gains and/or, Task 5 drops throw, abstract+`is` task deleted, 8/9 renumber to 7/8. Plan 9 gains core builtins. Plan 10 gains the 307 -> 0 diagnostic gate. WO-E205 re-filed unreachable-by- design. types.ml header drops its false satisfaction-set claim. 00-code- review.md reduced to a stub — its rival Phase 1-4 roadmap retired.

# 04 — Workspace layout + `wo.toml` grammar
|
||
|
||
**Context sources:** [`./00-overview.md`](./00-overview.md) §§ "Target layout" (L73–117), "Design decisions" 4–5 (L33–34), [`docs/examples/ecommerce/wo.toml`](../../../examples/ecommerce/wo.toml) (the workspace manifest already in the repo), [`docs/examples/ecommerce/apps/storefront/wo.toml`](../../../examples/ecommerce/apps/storefront/wo.toml) (the per-app manifest already in the repo), [`docs/examples/blog/`](../../examples/blog/) (the degenerate single-app form).
|
||
|
||
## Goal
|
||
|
||
Lock the `wo.toml` grammar at both workspace and per-app scope, fill any structural gaps in `docs/examples/ecommerce/` so its layout matches 00-overview's "Target layout" exactly, and ship a Rust workspace loader (`crates/app/src/workspace.rs` + sibling) that walks a workspace root, reads each app's manifest, and resolves `{{> partial}}` lookups across `shared = […]` directories first-match-wins.
|
||
|
||
## Design decisions (locked)
|
||
|
||
1. **`wo.toml` is TOML.** Not `.wo`. The workspace + app manifests already exist in the repo using TOML; this phase formalises the schema and adds a parser. Anchored in [`docs/examples/ecommerce/wo.toml`](../../../examples/ecommerce/wo.toml).
|
||
2. **Path-based shared dependencies, no registry.** `shared = ["../../shared/types", …]` resolves at parse time relative to the per-app `wo.toml`. No semver, no fetch. Anchored in [`./00-overview.md`](./00-overview.md) decision 4.
|
||
3. **Workspace root vs. single app, by `kind`/`app_kind` field.** A `wo.toml` with `kind = "workspace"` triggers workspace loading and reads `[workspace]`. A `wo.toml` with `app_kind = "app"` is a leaf app. A `wo.toml` with neither is a degenerate single-app workspace (the blog example) — loaded as if it were `apps/<itself>`.
|
||
4. **One screen per directory.** `apps/<X>/ui/<screen>/{<screen>.wo, <screen>.htmlx, <screen>.css}` is locked layout. The loader walks `apps/<X>/ui/*/` and registers each subdirectory as a screen. Anchored in [`./00-overview.md`](./00-overview.md) decision 5 + Target Layout (L98–103).
|
||
5. **Component resolution: app-local first, then shared in declared order.** `{{> money amount=x}}` looks in `apps/<X>/ui/components/` first, then each path in `[dependencies] shared = […]` in order. First match wins. Errors at compile time if the partial cannot be resolved.
|
||
|
||
## Scope
|
||
|
||
### New files inside `crates/app/src/`
|
||
|
||
| File | Responsibility | Port source |
|
||
| --- | --- | --- |
|
||
| `workspace.rs` | Parse workspace `wo.toml`, walk and load each app | new (~200 LOC) |
|
||
| `manifest.rs` | Per-app `wo.toml` schema (`AppManifest`) | new (~150 LOC) |
|
||
| `resolver.rs` | Component / type / logic path resolution across `shared = […]` | new (~120 LOC) |
|
||
| `mod.rs` | Re-exports `Workspace`, `App`, `AppManifest`, `WorkspaceError`, `ResolverError` | new (~30 LOC) |
|
||
|
||
Total: ~500 LOC.
|
||
|
||
### Existing files filled in (not new code)
|
||
|
||
`docs/examples/ecommerce/` — gap-fill any directories named in 00-overview's "Target layout" that don't yet exist (e.g. `shared/components/header.htmlx`, `apps/storefront/types/cart.wo`). Pure structural work; no runtime change.
|
||
|
||
### `Cargo.toml` change
|
||
|
||
```toml
|
||
[dependencies]
|
||
toml = "0.8"
|
||
```
|
||
|
||
`toml` is the explicit cost of skipping a hand-rolled TOML parser at this phase. The dependency-removal track will revisit when relevant; for prototype, parsing TOML by hand isn't worth the LOC.
|
||
|
||
### Workspace `wo.toml` schema
|
||
|
||
```toml
|
||
name = "ecommerce-workspace"
|
||
version = "0.1.0"
|
||
kind = "workspace"
|
||
|
||
[runtime]
|
||
wo = ">= 0.1"
|
||
|
||
[workspace]
|
||
apps = ["apps/storefront", "apps/admin"]
|
||
shared = ["shared/types", "shared/logic", "shared/components"]
|
||
|
||
[database]
|
||
listen = "127.0.0.1:5555"
|
||
data_dir = "./data"
|
||
isolation = "snapshot"
|
||
```
|
||
|
||
### Per-app `wo.toml` schema
|
||
|
||
```toml
|
||
name = "storefront"
|
||
version = "0.1.0"
|
||
app_kind = "app"
|
||
|
||
[dependencies]
|
||
shared = ["../../shared/types", "../../shared/logic", "../../shared/components"]
|
||
|
||
[server]
|
||
listen = ":8080"
|
||
|
||
[database]
|
||
url = "wo://127.0.0.1:5555"
|
||
api_key_env = "STOREFRONT_DB_KEY"
|
||
```
|
||
|
||
## API shape (target)
|
||
|
||
```rust
|
||
use app::{Workspace, App};
|
||
|
||
let ws = Workspace::load(Path::new("docs/examples/ecommerce"))?;
|
||
assert_eq!(ws.apps().len(), 2);
|
||
|
||
let storefront = ws.app("storefront").unwrap();
|
||
let money_partial = storefront.resolve_component("money")?; // shared/components/money.htmlx
|
||
let cart_type = storefront.resolve_type("Cart")?; // apps/storefront/types/cart.wo
|
||
|
||
// Degenerate form:
|
||
let blog = Workspace::load(Path::new("docs/examples/blog"))?; // single-app workspace
|
||
assert_eq!(blog.apps().len(), 1);
|
||
```
|
||
|
||
## Exit criteria
|
||
|
||
1. `cargo build -p app` green; the new `toml` dep compiles.
|
||
2. **Workspace load.** `Workspace::load(docs/examples/ecommerce)` returns 2 apps + 3 shared dirs and no errors.
|
||
3. **Component resolution.** `storefront.resolve_component("money")` returns the path to `shared/components/money.htmlx`. `storefront.resolve_component("nonsense")` errors as `ResolverError::NotFound`.
|
||
4. **App-local override.** Adding `apps/storefront/ui/components/money.htmlx` makes `resolve_component("money")` return the app-local path; removing it falls back to the shared one.
|
||
5. **Degenerate form.** `Workspace::load(docs/examples/blog)` loads as a one-app workspace; `wo run docs/examples/blog` continues to start unchanged.
|
||
6. `cd reference/crates && cargo build && cargo test`.
|
||
|
||
## Non-scope
|
||
|
||
- **No semver, no registry, no lockfile.** Path references only.
|
||
- **No `wo dev` hot-reload.** File watching against `apps/*/ui/` is deferred (would consume `reference/crates/wo-watch/`).
|
||
- **No cross-workspace symlinks.** `shared = […]` paths must resolve under the workspace root.
|
||
- **No build-time enforcement that an app touches only its declared shared dirs.** That's an integrity check for a later hardening phase.
|
||
- **No env-var interpolation in `wo.toml`.** `${VAR}` syntax stays out; runtime config comes through env vars at startup, not manifest time.
|
||
|
||
## Verification
|
||
|
||
```bash
|
||
cargo build -p app
|
||
cargo test -p app --test workspace_load
|
||
cargo test -p app --test resolver
|
||
|
||
# end-to-end inspection
|
||
cargo run --bin wo -- ls-apps docs/examples/ecommerce
|
||
# storefront apps/storefront
|
||
# admin apps/admin
|
||
|
||
cargo run --bin wo -- ls-apps docs/examples/blog
|
||
# blog .
|
||
|
||
# v1 regression
|
||
cargo run --bin wo -- run docs/examples/blog &
|
||
PID=$!; sleep 1; curl -fsS http://127.0.0.1:8080/ >/dev/null; kill $PID
|
||
|
||
cd reference/crates && cargo build && cargo test
|
||
```
|
||
|
||
## After this phase
|
||
|
||
The workspace layout is the input that phase 05 (`05-per-app-binaries.md`) compiles into a binary per app, and the namespace within which phase 06 (`06-shared-db-daemon.md`) issues per-app API keys. Phase 07 (`07-per-app-policies.md`) reads `apps/<X>/app.wo` for app-scope policy declarations whose location this phase locks.
