refactor(shared): add BLOB_PRESENTER, unlock the blob-to-browser success paths (RB-28)

Three application-layer commands ended in raw DOM calls (URL.createObjectURL,
window.open, document.createElement('a').click(), URL.revokeObjectURL) as
their last statement. jsdom cannot assert a call that is also the end of the
function, so each command's success path stayed unassertable, and
StamdataStore.download()'s two-clause guard stayed permanently dark on its
true branch (TE-006).

Add BLOB_PRESENTER (libs/shared/src/application/blob-presenter.ts), an
InjectionToken mirroring SESSION_PORT's shape: an interface with open()/
download(), a real implementation preserving the existing open()-never-
revokes vs download()-always-revokes asymmetry, provided in root. Route
StamdataStore.download(), BriefStore.previewLetter(), and
OrgTemplateStore.proefbrief() through it.

Add specs with a recording fake presenter: StamdataStore.download()'s guard
(both clauses) and its success path, asserting toJson(...)'s exact output
reaches the file; BriefStore.previewLetter()'s existing success test now
goes through the seam instead of spying on window/URL directly; a new
org-template.store.spec.ts (none existed before) covers proefbrief()'s
success and failure paths.

Verified red without the fix by editing the download() filename to the
wrong extension, watching the success-path spec fail, then restoring it.

# RB-28 — `BLOB_PRESENTER` token unlocks the three blob-to-browser success paths
Status: **implemented** · 2026-08-28 · Source finding: `02-testability.md` TE-006 ·
`99-backlog.md` RB-28
## What was wrong
Three application-layer commands each ended in raw DOM/browser calls that jsdom cannot
meaningfully execute: `StamdataStore.download()`
(`libs/beheer/src/application/stamdata.store.ts`) did `URL.createObjectURL`
`document.createElement('a')``a.click()``URL.revokeObjectURL`;
`BriefStore.previewLetter()` (`apps/ssp/src/app/brief/application/brief.store.ts`) and
`OrgTemplateStore.proefbrief()` (`apps/ssp/src/app/brief/application/org-template.store.ts`)
both did `window.open(URL.createObjectURL(blob), '_blank')`. Because the call was the
last statement of each command, TE-006 recorded the whole success path as effectively
unassertable, and `download()`'s two-clause guard (`if (!s || !this.canDownload())
return;`) as permanently dark on its true branch.
## What changed
One new file, `libs/shared/src/application/blob-presenter.ts`, mirroring the
`SESSION_PORT` token already in that folder — an interface, a production
implementation, and an `InjectionToken`:
```ts
export interface BlobPresenter {
open(blob: Blob): void;
download(blob: Blob, filename: string): void;
}
const realBlobPresenter: BlobPresenter = {
open(blob) {
window.open(URL.createObjectURL(blob), '_blank');
},
download(blob, filename) {
const url = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
a.download = filename;
a.click();
URL.revokeObjectURL(url);
},
};
export const BLOB_PRESENTER = new InjectionToken<BlobPresenter>('BLOB_PRESENTER', {
providedIn: 'root',
factory: () => realBlobPresenter,
});
```
`open()` never revokes the object URL (the tab it opens outlives the call —
`BriefStore.previewLetter`'s original comment already said so and is preserved,
moved onto the token's own doc comment); `download()` does revoke, once the click has
fired. This asymmetry is preserved deliberately, not unified — the two call sites
behaved differently before this ticket and still do.
Each of the three commands now injects `BLOB_PRESENTER` and calls it instead of the DOM
directly:
| File | Before (last statement) | After |
| ----------------------- | ---------------------------------------------------------------------------------- | ------------------------------------------------------------ |
| `stamdata.store.ts` | `createObjectURL``createElement('a')``click()``revokeObjectURL` (6 lines) | `this.blobPresenter.download(blob, \`${s.table.id}.json\`);` |
| `brief.store.ts` | `window.open(URL.createObjectURL(r.value), '_blank')` | `this.blobPresenter.open(r.value);` |
| `org-template.store.ts` | `window.open(URL.createObjectURL(r.value), '_blank')` | `this.blobPresenter.open(r.value);` |
`OrgTemplateStore.previewUrlFor` (added by RB-24, a different seam — a document
content URL for an `<a href>`, not a blob handoff) is untouched.
## Tests added
**`libs/beheer/src/application/stamdata.store.spec.ts`** — a new
`StamdataStore.download (RB-28)` describe block with a recording fake `BlobPresenter`:
1. Does not call the presenter while `canDownload()` is false because nothing is dirty
yet — the guard's previously-dark true branch, first clause.
2. Does not call the presenter while previewing a date, even with a real edit present —
the guard's true branch, second clause.
3. **The success path**, asserting `toJson(...)`'s exact output reaches the file: reads
the recorded blob's text and compares it byte-for-byte against a direct call to
`toJson(store.table()!, store.rows())`, and asserts the filename is
`professions.json`.
**`apps/ssp/src/app/brief/application/brief.store.spec.ts`** — the existing
`BriefStore.previewLetter` describe block's success test previously spied directly on
`window.open`/`URL.createObjectURL` (both already jsdom-spyable, since the properties
exist even though calling them for real throws "not implemented"). It now provides the
recording fake via `BLOB_PRESENTER` and asserts `opened` holds exactly the resolved
blob — the same outcome, reached through the new seam instead of monkey-patching two
global browser objects.
**`apps/ssp/src/app/brief/application/org-template.store.spec.ts`** (new file —
`OrgTemplateStore` had no spec at all before this ticket) — a
`OrgTemplateStore.proefbrief (RB-28)` describe block: the success path (presenter
receives the resolved blob, no error) and the failure path (presenter never reached,
error surfaced). A `Partial<UploadAdapter>` stub with a no-op `categoriesResource`
(status `'idle'`) satisfies the store's constructor effect without touching the
logo-upload sub-state, which these tests do not exercise.
## Verified red without the fix
Broke `StamdataStore.download()` with an `Edit` (not `git checkout`): changed the
filename from `` `${s.table.id}.json` `` to `` `${s.table.id}.csv` ``. Ran the new
success-path spec:
```
AssertionError: expected 'professions.csv' to be 'professions.json' // Object.is equality
Expected: "professions.json"
Received: "professions.csv"
libs/beheer/src/application/stamdata.store.spec.ts:134:36
```
Re-applied the correct filename with a second `Edit`; the full `stamdata.store.spec.ts`
file (6 tests) went green again.
## Verification
- **`grep` for remaining DOM blob calls** in all three stores —
`grep -nE "window\.open|createObjectURL|revokeObjectURL|createElement\('a'\)|\.click\(\)"` —
zero matches. The only occurrences of those calls anywhere in `apps`/`libs` are inside
`blob-presenter.ts` itself (checked with a second, unscoped grep — no fourth inlined
handoff exists).
- `npm run lint`: clean.
- `npm run dep:check`: unaffected (no new import direction — `libs/shared` still does not
depend on `libs/beheer`; both `libs/beheer` and `apps/ssp/brief` import the new token
from `libs/shared`, never the reverse).
- `npm test` (all four projects): all pass — ssp 276, behandelportal 37, shared 138,
beheer 26 (up from 23; +3 for the new `download()` describe block).
- Coverage, `npm run test:coverage` narrowed per project:
- `libs/beheer/src/application/stamdata.store.ts` — **before** BRH 15 / BRF 37
(40.5% branch, confirmed against the current tree, matching TE-006's citation
exactly); **after** BRH 25 / BRF 37 (**67.6% branch**). `libs/beheer/src/application`
has exactly this one file, so the module figure moves the same way.
- `apps/ssp/src/app/brief/application/brief.store.ts` — **before** BRH 39 / BRF 72
(54.2% branch). This is higher than TE-006's cited 32/64 (50%) because RB-22/RB-23
already added branches (the 404-tolerance path) since the finding was written — see
"What TE-006 got wrong" below. **After**: BRH 39 / BRF 72, unchanged — swapping the
global-spy assertions for the injected fake changes how the success branch is
reached in the spec, not whether it is reached; it was already covered before this
ticket (see below).
- `apps/ssp/src/app/brief/application/org-template.store.ts` — no spec existed before
this ticket, so there is no meaningful "before" branch figure for it specifically.
**After**: BRH 17 / BRF 77, including both `proefbrief()` branches newly covered.
- `npm run ci` (foreground, `timeout: 600000`, no background/Monitor): result reported
in the implementing agent's final answer.
## What TE-006 got wrong
TE-006 states: "`brief.store.spec.ts` demonstrates this exactly: it tests
`previewLetter`'s failure case ... and cannot test the success case." This is not
accurate for the code as it stood at the start of this ticket. The spec already had an
`'opens the composed letter in a new tab on success'` test that used
`vi.spyOn(URL, 'createObjectURL')` and `vi.spyOn(window, 'open')` to assert the success
path — jsdom defines both properties (as functions that throw "not implemented" if
actually invoked), so `vi.spyOn` can already replace them, and the pre-existing test
did. That test passed both before and after this ticket's change; this ticket did not
newly unlock `previewLetter`'s success path, it moved an already-passing assertion off
two hand-spied global browser objects and onto the new injectable seam. `git log
--follow -p` on the spec file shows this test dates to the WP-67 monorepo merge, not to
any of RB-22/23/24.
The seam is still worth having: `StamdataStore.download()`'s success path (five
DOM/API calls in a row: `createObjectURL`, `createElement`, `.href`, `.download`,
`.click()`, `revokeObjectURL`) is a materially harder thing to spy on faithfully than a
single `window.open` call, and was in fact still dark before this ticket (no
`download()` test of any kind existed). `OrgTemplateStore.proefbrief()` also had no
spec at all. TE-006's diagnosis (three commands share the same class of problem, one
token fixes all three) is sound; only the specific "cannot test" claim about
`previewLetter` overstates what was true for that one call site. Scope was not reduced
because of this — all three call sites are migrated per the ticket's own instruction to
ship them together rather than half-adopt the seam.
## What this ticket did not touch
`OrgTemplateStore.previewUrlFor` (RB-24) — confirmed present and unchanged at
`org-template.store.ts:78`. `libs/shared/src/application/upload-shell.service.ts`
(RB-25) and `upload-controller.ts` (RB-26) — not read beyond what RB-24's own note
already described, not edited. `libs/shared/docs/behaviour-spec.mdx` — regenerated by
`npm run gen:behaviour-spec` (part of `npm run ci`) to reflect the new/renamed test
names; never hand-edited.
