release prep v0.1.2: collapse audit fixes into v0.1.2

The previous commit (0cceefc) staged the audit-driven fixes under a
hypothetical v0.1.3 since v0.1.2 hadn't tagged yet. Tagging cadence
decision: ship them all as v0.1.2 — there's no point spending a tag
on the clean-shutdown fix alone when v0.1.3 was already lined up
behind it. PLAN.md §13 + CHANGELOG.md collapse v0.1.2 + v0.1.3 into
the single v0.1.2 entry, dated 2026-05-03; orphaned [0.1.3] link
reference at the foot of CHANGELOG removed.

No code changes — the four fixes from 0cceefc + f132c3c stand as-is.

+## [0.1.2] — 2026-05-03
+
+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.
+
+### Fixed
+
+- **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.

+### v0.1.1 — shipped 2026-05-03
 
-All four shakedown follow-ups landed:
+Closed the four shakedown follow-ups identified during v0.1.0 shipping:
 
 - **perfsmoke gap closed.** `HealthController` now constructor-injects `Publisher`; `/healthz` returns 200 only when `BridgeBundle` is fully container-resolvable. The `bundle` field in the response is the canary value perfsmoke + the bundled-mode integration test both check.
 - **Bundled-mode supervisor integration test.** `examples/todo/tests/bundled-supervisor.sh` (run via `make integration-bundled`) stages a fake AppImage layout in `/tmp` and exercises the whole supervisor codepath (`resolveFrankenphpBin` → `runMigrations` → `spawnChild` → cache/log redirect to user data dir) without needing a real `.AppImage` build. Wired into ci.yml. Catches every v0.1.0 shakedown bug.
 - **Skeleton AppImage parity.** `framework/skeleton/Makefile` gains `staging-symfony` + `appimage` targets mirroring the example's; `framework/skeleton/packaging/` ships starter `.desktop` + `.png`; `bin/php-qml-init` rewrites `BUNDLE_SRC` / `PACKAGING` Make variables and renames packaging files at scaffold time. `--vendor` mode also vendors `packaging/linux/` to `.bridge-packaging/`. Scaffolded apps inherit a working `make appimage` flow.
 - **Caddyfile fmt.** `framework/skeleton/Caddyfile` and `examples/todo/Caddyfile` reformatted per `caddy fmt`; the "Caddyfile input is not formatted" boot warning is gone.
+- **Cache-wipe on bundled launch** (added during v0.1.1 shakedown). Symfony bakes `kernel.project_dir` into its compiled cache; the AppImage's FUSE mount path changes per launch, so cache from launch N is stale by N+1. Supervisor now wipes `var/cache/` on every `initBundledMode`. Build-time cache warmup is the v0.2.0 follow-up.
+
+### v0.1.2 — shipped 2026-05-03
+
+Bugfix release. Bundles the v0.1.1 follow-up that surfaced during the cycle (clean child shutdown) with three non-breaking fixes from a post-v0.1.1 architecture audit:
+
+- **Bundled supervisor: clean child shutdown.** The destructor's `teardownChild()` only ran during stack unwinding *after* `app.exec()` returned, by which point Qt's event loop was already mid-shutdown — so `QProcess::waitForFinished` couldn't reliably reap the child and Qt warned `QProcess: Destroyed while process is still running`, leaving an orphan frankenphp + its workers behind. Fix: connect `QCoreApplication::aboutToQuit` to `teardownChild` in the constructor, so the child is SIGTERM'd while the event loop is still active. 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.** `BridgeResourceMaker` and `BridgeWindowMaker` carried docstrings claiming the QML output dir was settable via the bundle's `qml_path` option, but the bundle never wired one — the constructor default was the only knob. `BridgeBundle::configure` now defines a `qml_path` node (default `../qml/`); `loadExtension` exposes it as the `bridge.qml_path` container parameter; `services.yaml` binds it into both makers. Apps configure with `config/packages/bridge.yaml`: `bridge: { qml_path: ../qml/ }`. Default is unchanged so existing skeleton/example apps need no edit.
+- **`SessionAuthenticator` problem+json on entry-point path.** `onAuthenticationFailure` already returned RFC 7807 `application/problem+json` for *bad-token* requests, but Symfony's default entry point fired for *no-token* requests — yielding a Form-flavoured 302/401 instead. Implemented `AuthenticationEntryPointInterface::start`, factored the response into a `problemJson()` helper, so QML's RestClient sees one shape regardless of which path the firewall takes. Added test coverage.
+- **`CorrelationKeyListener::onTerminate` sub-request guard.** `onRequest` already had `isMainRequest()`, but `onTerminate` cleared unconditionally — so 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. Defensive: real-world impact is low (FrankenPHP worker mode does not currently emit sub-requests), but cheap to fix and the obvious correctness bug.
 
 ### v0.2.0 — next minor
 
-Pulls in the originally-Phase-3/5-deferred items that don't need new operational dependencies, plus the smaller §12 risks. Cross-platform packaging is parked at v0.9.0 — the operational lift (self-hosted runners + platform certs) is too big to fold into the next minor and Linux remains the primary target until the framework's surface stabilises.
+Pulls in the originally-Phase-3/5-deferred items that don't need new operational dependencies, plus the smaller §12 risks **and** the public-API / DX items surfaced by the post-v0.1.2 audit. Cross-platform packaging is parked at v0.9.0 — the operational lift (self-hosted runners + platform certs) is too big to fold into the next minor and Linux remains the primary target until the framework's surface stabilises.
+
+**Public-API surface (audit-driven, breaks pre-1.0 SemVer permitted):**
+
+- **Ship interfaces for the bridge's three public services.** `Publisher`, `ModelPublisher`, and `CorrelationContext` are typehinted concretely everywhere (the Doctrine listener, the example `PingController`, every user controller that wants to fire a manual envelope) — the matching upstream Symfony idiom is `HubInterface` / `EventDispatcherInterface` / `NormalizerInterface`. Extract `PublisherInterface`, `ModelPublisherInterface`, `CorrelationContextInterface`; have the concrete classes implement them; switch every internal typehint over; document the interfaces as the public contract. Lets app code mock at the seam without a concrete-class spy and lets us iterate the implementations behind the contract.
+- **`BridgeOp` enum.** `'upsert'` / `'delete'` are passed as raw strings between `DoctrineBridgeListener` and `ModelPublisher::publishEntityChange`. PHP 8.1 backed enum is the obvious typed replacement; PLAN.md §4's envelope `op` field already enumerates `upsert` | `delete` | `replace` | `event` so the enum encodes a documented contract. Method signature change is API-visible — pre-1.0 SemVer permits it; ship deprecation paths if the audit surfaces external callers.
+- **`HealthController` deep-load canary refactor.** Constructor-injects `Publisher` only as a "is the bundle resolvable" probe (added in v0.1.1). Switching the dependency to a tiny `BridgeBundleInfo` value object that the bundle registers documents intent and decouples `/healthz` from the publisher contract — important once `PublisherInterface` lands.
+
+**Maker DRY + DX (audit-driven):**
+
+- **Maker shared helpers.** All three makers re-implement the same name-prompt-or-fail closure (`ucfirst(trim(…))` plus throw on empty) and re-spell their own camel-to-snake / camel-to-kebab regexes inline. Extract `Maker\Support\NameInput::askOrFail()` and `Maker\Support\Naming::camelTo($name, '_'|'-')` — single source of truth, three call sites.
+- **DTO-shaped controller scaffold (`make:bridge:resource --with-dto`).** Generated CRUD controllers currently accept any JSON shape: `if (isset($data['title'])) …` with silent type coercion, no required-field enforcement, malformed JSON swallowed as `?? []`. Add a `--with-dto` option that emits `Create<Name>Dto` + `Update<Name>Dto` DTOs alongside the controller and rewrites the action signatures to `#[MapRequestPayload] CreateTodoDto $dto`. Pulls `symfony/validator` into the skeleton/example dependencies; `#[Assert\NotBlank]` on title fields is the headline default. Symfony's payload-mapping infrastructure produces RFC 7807 problem+json on validation failure for free, fixing the field-mapping repetition between `create()` and `update()` at the same time. Once stable, flip `--with-dto` to default-on.
+- **Generated controller `findOr404` boilerplate.** `update()` and `delete()` both inline the find-or-404 problem+json response. Either factor a private helper into the template or migrate to Symfony's `#[MapEntity]` attribute (ships in 7.x).
 
 **Makers + reactive types (Phase 3.x deferred):**
