All notable changes to this project are documented here.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). Pre-v1.0.0, minor bumps may break public API.
This section tracks work landing on `dev` toward **v0.2.0** (next minor; pre-1.0 SemVer permits API breaks). See PLAN.md §13 for the full v0.2.0 scope.
- **`PublisherInterface`, `ModelPublisherInterface`, `CorrelationContextInterface`.** The bridge's three public services now ship as interfaces (same namespace as concrete, mirroring upstream `HubInterface`/`Hub`). App controllers and listeners should typehint these instead of the concrete classes so swappable implementations (offline-buffer publisher, request-stamp correlation context, etc.) remain non-breaking. Existing `Publisher` / `ModelPublisher` / `CorrelationContext` classes implement the new interfaces unchanged.
- **`BridgeOp` enum.** PHP 8.1 string-backed enum (`Upsert` / `Delete` / `Replace` / `Event`) replacing the raw `'upsert'`/`'delete'` strings previously passed between `DoctrineBridgeListener` and `ModelPublisher::publishEntityChange`. Values match PLAN.md §4's envelope `op` wire format. Typo'd ops are now caught at the type level instead of silently producing envelopes clients ignore.
- **`BridgeBundleInfo` value object** carrying the bundle's name + class FQCN. `HealthController` now constructor-injects this instead of `PublisherInterface` as the deep-load canary, so the readiness probe is no longer coupled to the publisher's contract. `/healthz` response gains a `name` field (`php-qml/bridge`); the `bundle` field now reports `PhpQml\Bridge\BridgeBundle` (was `PhpQml\Bridge\Publisher`).
- **`Maker\Support\NameInput`** — shared interactive name prompt. All three `make:bridge:*` makers (`resource`, `command`, `window`) re-implemented the same "prompt, trim, ucfirst, reject empty" closure inline; collapsed into one call site so empty-argument and validation behaviour stay in lockstep.
- **Internal typehints switched to interfaces.** `ModelPublisher` constructor takes `PublisherInterface` + `CorrelationContextInterface`; `DoctrineBridgeListener` takes `ModelPublisherInterface`; `HealthController` takes `BridgeBundleInfo`; the skeleton's `PingController` takes `PublisherInterface`. Autowire continues to inject the concrete implementations transparently.
- **`/healthz` response shape.** `bundle` field's value changes from `PhpQml\Bridge\Publisher` to `PhpQml\Bridge\BridgeBundle`; new `name` field reports the Composer package name. JSON consumers ignoring unknown keys are unaffected; consumers asserting the `bundle` value need to migrate.
- **`ModelPublisher::extractId` reflection cleanup.** Removed the `setAccessible(true)` call (deprecated since PHP 8.1; all properties are accessible via Reflection without it).
Bugfix release. Bundles the v0.1.1 follow-up that surfaced during the v0.1.2 cycle (bundled-mode supervisor cleanly SIGTERMs its child on host exit) with three non-breaking fixes from a post-v0.1.1 architecture audit.
- **Bundled supervisor: clean child shutdown.** `BackendConnection`'s destructor was the only path that called `teardownChild()`, but it ran during stack unwinding *after*`app.exec()` returned — by then the Qt event loop was already mid-shutdown and `QProcess::waitForFinished` couldn't reliably reap the child. Symptom: Qt logged `QProcess: Destroyed while process ("...frankenphp") is still running`, frankenphp + its PHP workers became orphans. The constructor now also connects `QCoreApplication::aboutToQuit` → `teardownChild`, so the child is SIGTERM'd while the event loop is still active. The bundled-supervisor integration test gained a clean-shutdown assertion (no Qt warning + no orphan frankenphp under the host's PGID after SIGTERM).
- **`bridge.qml_path` is now actually configurable.** The `BridgeResourceMaker` and `BridgeWindowMaker` docstrings claimed the QML scaffold path was settable via the bundle's `qml_path` option, but the bundle's `configure()` was empty and the constructor default (`'../qml/'`) was the only knob. `BridgeBundle::configure` now defines a `qml_path` scalar node; `loadExtension` exposes it as the `bridge.qml_path` container parameter; `services.yaml` binds it into both makers. Apps can override with `config/packages/bridge.yaml`: `bridge: { qml_path: ../qml/ }`. Default unchanged.
- **`SessionAuthenticator`: problem+json on the entry-point path.** `onAuthenticationFailure` already returned RFC 7807 `application/problem+json` for *bad-token* requests, but Symfony's default `AuthenticationEntryPointInterface::start` fired for *no-token* requests, returning a Form-flavoured 302/401 with the wrong shape for QML's `RestClient` error mapping. The authenticator now implements `AuthenticationEntryPointInterface` and routes both paths through a shared `problemJson()` helper so QML sees one error shape regardless of which firewall path was taken. New test covers the entry-point response.
- **`CorrelationKeyListener::onTerminate` sub-request guard.** `onRequest` already guarded with `isMainRequest()`, but `onTerminate` cleared unconditionally — a sub-request finishing mid-controller would wipe the main request's correlation key, causing the matching Mercure echo to lose its `correlationKey` field and the optimistic UI to never reconcile. FrankenPHP worker mode does not currently emit sub-requests so the user-visible impact is nil, but the asymmetry was a defensive bug.
Bugfix release closing the four follow-ups identified during the v0.1.0 shakedown. No new public API surface; `/healthz` response gains an additive `bundle` field (existing JSON consumers ignore unknown keys).
- **Wipe Symfony cache on bundled-mode launch.** Symfony's compiled container bakes `kernel.project_dir` as an absolute path. In bundled mode that path lives inside the AppImage's FUSE mount (`/tmp/.mount_<random>`), which is regenerated every launch. So the cache from launch N referenced mount-N's path; launch N+1 (different mount) hit `InvalidDirectory` from doctrine-migrations on the first launch-2 (and similar at any kernel.project_dir-sensitive lookup). `BackendConnection::initBundledMode` now `rmdir`s the cache before each spawn. Costs ~1-2s of warmup per launch; build-time cache warmup is the permanent fix (PLAN.md §13 v0.2.0). The bundled-supervisor integration test gained a 2nd-launch-from-fresh-staging step so this regresses if forgotten.
- **`HealthController` deep-loads the bundle.** Constructor-injects `Publisher` so `/healthz` returns 200 only when `BridgeBundle` is fully container-resolvable. v0.1.0's `/healthz` returned 200 against half-loaded bundles — both the path-repo symlink dangling at runtime and the read-only-cache failure shipped green through perfsmoke as a result. Response body now includes `bundle: "PhpQml\\Bridge\\Publisher"` as the canary value.
- **Caddyfile formatting.** `framework/skeleton/Caddyfile` and `examples/todo/Caddyfile` reformatted with `caddy fmt`. The "Caddyfile input is not formatted; run 'caddy fmt --overwrite'" warning that fired on every FrankenPHP boot is gone.
### Added
- **Bundled-mode supervisor integration test** (`examples/todo/tests/bundled-supervisor.sh`, `make integration-bundled`). Stages a fake AppImage layout in `/tmp` (host binary copied — Qt's `applicationDirPath()` dereferences symlinks via `/proc/self/exe`, so the real layout has to be mimicked closely; staged Symfony tree is `chmod -R a-w` to actually exercise the read-only-mount cache redirect) and exercises the supervisor end-to-end without needing a real `.AppImage` build. Asserts `/healthz` deep-load + cache redirect. Wired into `.gitea/workflows/ci.yml` after the existing dev-mode integration test.
- **Skeleton AppImage parity.** `framework/skeleton/Makefile` gains `staging-symfony` + `appimage` targets mirroring `examples/todo/Makefile`'s. New `framework/skeleton/packaging/skeleton.{desktop,png}` provide minimal AppImage assembly inputs. `bin/php-qml-init` now: (a) renames packaging files to match the scaffolded app name, (b) rewrites the `.desktop` file's `Name`/`Exec`/`Icon`, (c) substitutes the new `BUNDLE_SRC` and `PACKAGING` Makefile variables to either absolute framework paths (default) or vendored `.bridge` / `.bridge-packaging` paths (`--vendor`). Scaffolded apps inherit `make appimage` working out of the box.
### Notes
-`BackendConnection::m_port` stays hardcoded to 8765 — port-collision between two installed php-qml apps is a real bug surfaced during v0.1.1 prep, but the fix touches every consumer that hardcodes 8765 (perfsmoke, the new bundled-supervisor test) so it's tracked as a v0.2.0 item rather than a v0.1.x bugfix.
First public preview. Phases 0 through 4a in PLAN.md are complete plus the Phase 5 DX-polish sub-commits. Linux is the only packaged target; macOS and Windows are deferred to 4b / 4c. Tagging is the user's call (release CI runs on `v*` tags).
### Added
- **Process-pair architecture.** Qt/QML host owns rendering; bundled FrankenPHP child runs the Symfony app in worker mode. They communicate via local HTTP and Mercure SSE.
- **Symfony bundle (`php-qml/bridge`).** `BridgeBundle` wires Doctrine subscriber, `ModelPublisher`, `bridge:doctor` console command, and the `#[BridgeResource]` attribute so app code stays idiomatic Symfony.
- **Skeleton application** (`framework/skeleton`) — minimal reference app exercised by every CI job.
- **POC todo app** (`examples/todo`) — full list UI, multi-window mirror, mark-all-done command, end-to-end test of multi-window coherence and crash-recovery.
- **bundled mode.** When `BRIDGE_URL` is unset (typical AppImage case), `BackendConnection` spawns the embedded FrankenPHP, generates a per-session bearer token, runs first-launch migrations into `~/.local/share/<app>/var/data.sqlite`, and supervises the child with `prctl(PR_SET_PDEATHSIG, SIGTERM)` for cleanup safety.
- **Linux AppImage packaging.** `packaging/linux/build-appimage.sh` + `make appimage` produce a single ~150 MB binary (Qt + Symfony + FrankenPHP + AppImageUpdate sidecar).
- **AppImageUpdate auto-update.** Embedded `update-info` ELF section points at the canonical Gitea Releases URL. `BackendConnection.checkForUpdates()` / `applyUpdate()` invoke the bundled sidecar.
- **Release CI** (`.gitea/workflows/release.yml`). Triggers on `v*` tags. Builds the AppImage, runs `tests/perfsmoke.sh` against PLAN.md §11 budgets (bundle ≤ 200 MB, cold start ≤ 4 s on shared CI runners, idle RSS ≤ 200 MB), generates zsync metadata + `latest.json` appcast + `SHA256SUMS`, optionally GPG-signs them, and uploads everything to the Gitea Release.
- **Quality CI** (`.gitea/workflows/ci.yml`). PHPStan + php-cs-fixer (check) + PHPUnit + qmllint + maker snapshot test + bridge-integration test (HTTP/SSE round-trip + crash-recover) on every push to `main`.
- **DX polish (Phase 5):**
-`DevConsole.qml` — opt-in window into the bundled FrankenPHP child's merged stdout/stderr; 500-line ring buffer; `Ctrl+`` toggles it in skeleton + todo example.
-`bin/php-qml-init <name>` — bash scaffolder. Copies `framework/skeleton/`, rewrites identifiers, repoints the path-composer-repo and CMake `add_subdirectory(framework/qml)` reference, runs `composer install` and migrations. `--vendor` produces a portable copy.
-`.vscode/launch.json` + `tasks.json` + `settings.json` and `.idea/runConfigurations/` shipped with skeleton and todo example.
- Hot-reload story documented end-to-end (FrankenPHP `--watch`, Qt Creator Reload, `qmlls` live preview).
- Licensed under **LGPL-3.0-or-later** (`LICENSE` + `LICENSE.GPL` at the repo root). Chosen to align with Qt 6's LGPLv3 licensing — see PLAN.md §12 for the relinkability obligations the AppImage build already honours.
