## Add Taskfile for unified dev workflow
### Summary
- Introduces [Taskfile](https://taskfile.dev/) as the single CLI entry
point for all development workflows across backend, frontend, engine,
Docker, and desktop
- ~80 tasks organized into 6 namespaces: `backend:`, `frontend:`,
`engine:`, `docker:`, `desktop:`, plus root-level composites
- All CI workflows migrated to use Task
- Deletes `engine/Makefile` and `scripts/build-tauri-jlink.{sh,bat}` —
replaced by Task equivalents
- Removes redundant npm scripts (`dev`, `build`, `prep`, `lint`, `test`,
`typecheck:all`) from `package.json`
- Smart dependency caching: `sources`/`status`/`generates`
fingerprinting, CI-aware `npm ci` vs `npm install`, `run: once` for
parallel dep deduplication
### What this does NOT do
- Does not replace Gradle, npm, or Docker — Taskfile is a thin
orchestration wrapper
- Does not change application code or behavior
### Install
```
npm install -g @go-task/cli # or: brew install go-task, winget install Task.Task
```
### Quick start
```
task --list # discover all tasks
task install # install all deps
task dev # start backend + frontend
task dev:all # also start AI engine
task test # run all tests
task check # quick quality gate (local dev)
task check:all # full CI quality gate
```
### Test plan
- [ ] Install `task` CLI and run `task --list` — verify all tasks
display
- [ ] Run `task install` — verify frontend + engine deps install
- [ ] Run `task dev` — verify backend + frontend start, Ctrl+C exits
cleanly
- [ ] Run `task frontend:check` — verify typecheck + lint + test pass
- [ ] Run `task desktop:dev` — verify jlink builds are cached on second
run
- [ ] Verify CI passes on all workflows

## Fix Playwright E2E tests and expand CI to run full suite
### Problem
The full Playwright suite was broken in two ways:
1. **`ConvertE2E.spec.ts` crashed at import time** —
`conversionEndpointDiscovery.ts` imported a React hook at the top level,
which pulled in the entire component tree. That chain eventually
required `material-symbols-icons.json` (a generated file that didn't
exist), crashing module resolution before any tests ran.
2. **CI only ran cert validation tests** — both `build.yml` and
`nightly.yml` hardcoded `src/core/tests/certValidation` as the test
path, silently ignoring everything else.
### Changes
**`ConvertE2E.spec.ts` — complete rewrite**
The old tests were useless in practice: all 9 dynamic conversion tests
were permanently skipped unless a real Spring Boot backend was running
(they called a live `/api/v1/config/endpoints-enabled` endpoint at
module load time). Replaced with 4 focused tests that use `page.route()`
mocking — no backend required, same pattern as
`CertificateValidationE2E`.
New tests cover:
- Convert button absent before a format pair is selected
- Successful PDF→PNG conversion shows a download button (mocked API
response)
- API error surfaces as an error notification
- Convert button appears and is enabled after selecting valid formats
**`conversionEndpointDiscovery.ts` — deleted**
Only existed to support the old tests. The `useConversionEndpoints`
React hook it exported was never imported anywhere else.
**`ReviewToolStep.tsx`**
Added `data-testid="download-result-button"` to the download button —
required for the happy-path test assertion.
**CI workflows (`build.yml`, `nightly.yml`)**
- Added a `Generate icons` step before Playwright runs (`node
scripts/generate-icons.js`) — the icon JSON is generated by `npm run
dev` locally but skipped by `npm ci` in CI
- Removed the `src/core/tests/certValidation` path filter so the full
suite runs
## PR: Certificate Pre-Validation for Document Signing
### Problem
When a participant uploaded a certificate to sign a document, there was
no validation at submission time. If the certificate had the wrong
password, was expired, or was incompatible with the signing algorithm,
the error only surfaced during **finalization** — potentially days
later, after all other participants had signed. At that point the
session is stuck with no way to recover.
Additionally, `buildKeystore` in the finalization service only
recognised `"P12"` as a cert type, causing a `400 Invalid certificate
type: PKCS12` error when the **owner** signed using the standard
`PKCS12` identifier.
---
### What this PR does
#### Backend — Certificate pre-validation service
Adds `CertificateSubmissionValidator`, which validates a keystore before
it is stored by:
1. Loading the keystore with the provided password (catches wrong
password / corrupt file)
2. Checking the certificate's validity dates (catches expired and
not-yet-valid certs)
3. Test-signing a blank PDF using the same `PdfSigningService` code path
as finalization (catches algorithm incompatibilities)
This runs on both the participant submission endpoint
(`WorkflowParticipantController`) and the owner signing endpoint
(`SigningSessionController`), so both flows are protected.
#### Backend — Bug fix
`SigningFinalizationService.buildKeystore` now accepts `"PKCS12"` and
`"PFX"` as aliases for `"P12"`, consistent with how the validator
already handles them. This fixes a `400` error when the owner signed
using the `PKCS12` cert type.
#### Frontend — Real-time validation feedback
`ParticipantView` gains a debounced validation call (600ms) triggered
whenever the cert file or password changes. The UI shows:
- A spinner while validating
- Green "Certificate valid until [date] · [subject name]" on success
- Red error message on failure (wrong password, expired, not yet valid)
- The submit button is disabled while validation is in flight
#### Tests — Three layers
| Layer | File | Coverage |
|---|---|---|
| Service unit | `CertificateSubmissionValidatorTest` | 11 tests — valid
P12/JKS, wrong password, corrupt bytes, expired, not-yet-valid, signing
failure, cert type aliases |
| Controller unit | `WorkflowParticipantValidateCertificateTest` | 4
tests — valid cert, invalid cert, missing file, invalid token |
| Controller integration | `CertificateValidationIntegrationTest` | 6
tests — real `.p12`/`.jks` files through the full controller → validator
stack |
| Frontend E2E | `CertificateValidationE2E.spec.ts` | 7 Playwright tests
— all feedback states, button behaviour, SERVER type bypass |
#### CI
- **PR**: Playwright runs on chromium when frontend files change (~2-3
min)
- **Nightly / on-demand**: All three browsers (chromium, firefox,
webkit) at 2 AM UTC, also manually triggerable via `workflow_dispatch`
