refactor(shared): move the accept/reject decision into planFileSelection (RB-26)

createUploadController required inject(), an effect(), and a window listener
before a test could reach it. The file-selection policy trapped behind that
cost now lives in a pure function, planFileSelection, in upload.machine.ts.

planFileSelection takes plain { name, type, size } objects, not File, and
decides per file whether to reject it or accept it, with no I/O. The
controller executes the plan: it dispatches a rejection as-is, and starts the
upload for an accepted file (the one step that needs crypto.randomUUID()).

A new spec covers the three outcomes: the 'multiple' batch rejection, a
rejectReason-based rejection, and the accept case, plus order in a mixed
batch. Verified red-then-green with a temporary stub, undone by a second edit.

No change to the controller's public surface or to the calling organism.
previewUrlFor (added by RB-24) is untouched.

# RB-26 — move the accept/reject decision into `planFileSelection` (`upload.machine.ts`)
Status: **implemented** · 2026-08-28 · Source finding: `02-testability.md` TE-004 ·
`99-backlog.md` RB-26 · Depends on `implementation/rb-24.md` (moved the upload files into
`infrastructure`/`domain`/`application`)
## What was wrong
TE-004: `createUploadController` does three `inject()` calls, registers an `effect()`, and
adds a `window` focus listener, all before it returns. A spec must run inside a `TestBed`
injection context with `UploadAdapter`, `UploadShellService`, and `DestroyRef` all
satisfied to reach anything inside it. What sits behind that cost is real policy:
`onFileSelected` decides, per file, whether to reject it with reason `'multiple'`, reject
it with a `rejectReason` result, or start its upload — a decision over
`(categories, categoryId, files)` with no I/O in it. `rejectReason`, the predicate that
decision calls, was already exported and spec'd; the decision that calls it was not.
## What changed
`libs/shared/src/domain/upload.machine.ts` gains one pure export:
```ts
export function planFileSelection(
state: UploadState,
categoryId: string,
files: { name: string; type: string; size: number }[],
): UploadMsg[];
```
It takes plain `{ name, type, size }` objects, not `File` — a spec needs no DOM. The body
is the old `onFileSelected` decision, moved: an unknown category plans nothing; too many
files for a single-file category plans one `FileRejected` with reason `'multiple'` and
skips the per-file checks; otherwise each file is judged by `rejectReason` and plans
either a `FileRejected` or a `FileSelected` entry, one entry per input file, in order.
`libs/shared/src/application/upload-controller.ts`'s `onFileSelected` now maps `selected:
File[]` to plain candidates, calls `planFileSelection`, and executes the result: a
`FileRejected` entry dispatches as-is; anything else starts the upload for the file at
that same array index (`crypto.randomUUID()`, `files.set()`, `shell.upload()` — the three
things that must stay impure and stay in the controller). No other method changed.
`previewUrlFor` (added by RB-24) is untouched.
## The `localId` placeholder — a deliberate, contained choice
An accepted file's planned `FileSelected` entry carries `localId: ''`. A real id needs
`crypto.randomUUID()`, and the ticket is explicit that call stays in the controller, not
the domain. The controller reads only each entry's `.type` to route it — it dispatches a
`FileRejected` entry verbatim, but for a `FileSelected` entry it discards the entry and
calls `start(categoryId, selected[i])`, which builds its own message with a real id.
The placeholder is therefore never dispatched. This was the only way found to keep the
return type exactly `UploadMsg[]` (as the ticket's own code sketch specifies) while still
letting the plan carry a per-file, order-preserving "start this one" signal — the
`FileRejected` variant carries no file identity (state keys rejections by category only),
so position in the returned array is what the controller uses to find the matching
original `File`. A discriminated `{ kind: 'reject' | 'start'; msg? }` return would avoid
the placeholder but was not built, since the ticket's signature is explicit and the
placeholder design meets it without changing behaviour.
## Behaviour
Same messages, same order, for the same inputs. Tracing all three original branches:
- Unknown category: original returns without dispatching; new code calls `planFileSelection`
(returns `[]`), then `forEach` over an empty array — no dispatch, no start.
- Too many files for a single-file category: original dispatches one `FileRejected`
('multiple') and returns; new code gets a one-entry plan and dispatches that one entry —
`forEach` never reaches indices past the plan's length, so no file starts.
- Per-file loop: original dispatches `FileRejected` or calls `start` for each file, in
order; new code's plan has one entry per file, in the same order, and the controller
dispatches or starts at each index identically.
## Testing
`libs/shared/src/domain/upload.machine.spec.ts` gained a `planFileSelection` describe
block: unknown category (plans nothing), the `'multiple'` batch rejection, a passing
single file against a single-file category, `rejectReason`'s two reject cases (`'type'`,
`'size'`) reached through the plan, the accept case's exact `FileSelected` shape
(including the `localId: ''` placeholder), and a mixed multiple-file case asserting
order (`['FileSelected', 'FileRejected', 'FileSelected']`).
**Proved red before green**, per the ticket's instruction not to use `git checkout`:
temporarily replaced the function body with a stub returning `[]` unconditionally (an
edit, not a revert), ran `ng test shared`, and got:
```
Test Files 1 failed | 23 passed (24)
Tests 6 failed | 139 passed (145)
```
The 6 failures were the `'multiple'` rejection, both `rejectReason` cases, the accepted-
file shape, and the mixed-order case — every outcome that depends on the real branching,
each failing with `expected [] to deeply equal [...]`. The unknown-category case passed
even against the stub, since both the stub and the real implementation return `[]` there
— expected, not a gap, since that branch has no policy to exercise. A second edit restored
the real body; the same run returned to `24 passed / 145 passed`.
## Scope held
No change to `createUploadController`'s construction, the `effect()`, or the `window`
listener — those are RB-25/RB-27's targets (RB-25 is `UploadShellService`, running
concurrently in the same commit window; RB-27 is `upload.adapter.ts`'s XHR closure).
Neither file was touched. The controller's public surface (`previewUrlFor`,
