MercureClient is a single-topic SSE subscriber: opens a long-lived GET
on the hub URL with the topic query and Accept: text/event-stream,
parses the line protocol into update(data, id) signals, and reconnects
with 1s→2s→…→30s exponential backoff on drop. Tracks lastEventId across
reconnects and sends it as Last-Event-ID so the hub can replay missed
messages — backing the "Sleep / wake" path in PLAN.md §3 *Edge cases*.
One client per topic by design; multi-topic aggregation is Phase 2.
RestClient.qml is a Promise-style XMLHttpRequest wrapper. Auto-attaches
an RFC4122-v4 Idempotency-Key to every non-GET request (PLAN.md §4 and
§7) so retries are safe by default. Maps application/problem+json error
bodies into structured rejections for downstream UI.
Standalone CMake build remains green.

BackendConnection (QML singleton via create() factory) reads BRIDGE_URL
and BRIDGE_TOKEN from env, periodically probes <url>/healthz with a 2s
transfer timeout, and exposes a Connecting/Online/Error state machine
plus error/token properties to QML. Bundled-mode startup (spawning the
embedded FrankenPHP child) is a Phase 4 deliverable; restart() is a
no-op for now. tokenRotated signal is reserved for the per-session
secret rotation described in PLAN.md §3.
SingleInstance is C++-only — main() must call acquireOrForward() before
the QML engine boots, so it's exposed via context property rather than
QML_SINGLETON. QLocalServer-based lock with stale-socket detection,
launch-arg forwarding via QDataStream, and the deadlock-avoiding race
fallback specified in §3 *Edge cases*.
CMakeLists.txt declares the PhpQml.Bridge static QML module with both
sources and is dual-mode: stands alone for sanity builds, integrates
via add_subdirectory from the skeleton's top-level CMake (Phase 1
sub-commit 6). Standalone build verified clean.

Console command bridge:doctor surfaces actionable hints for env / wiring
problems so first-run failures aren't a "connection refused" mystery.
Checks PHP version, ext-curl, ext-json, the Publisher service is wired
(meaning BridgeBundle loaded), and the BRIDGE_TOKEN / MERCURE_URL /
MERCURE_PUBLISHER_JWT_KEY / MERCURE_SUBSCRIBER_JWT_KEY env vars. With
--connect, also probes the configured URL via plain stream context (no
extra dep) and fails the run when unreachable.
CommandTester suite covers green path, missing-env path, and an
unreachable-URL probe — 11 tests, 32 assertions, all green.
Skeleton's Makefile target stays a TBD until sub-commit 6 stands up the
Symfony app the command runs from.

Bundle code for php-qml/bridge: BridgeBundle (AbstractBundle, autoloads
config/services.yaml), Publisher (thin wrapper over Mercure HubInterface
that enforces envelope-as-JSON), SessionAuthenticator (bearer-token
custom Symfony authenticator with problem+json failures), and
HealthController (GET /healthz readiness probe).
Composer constraints bumped to Symfony ^8.0 across the board (per user
request); mercure component to ^0.7. PHPUnit 11 suite covers Publisher
publish + private flag and SessionAuthenticator support/auth/failure
paths — 8 tests, 22 assertions, all green.
PLAN.md §13 updated to record the Symfony 8 minimum.

Stands up the directory structure Phase 1 fills in over subsequent
sub-commits: framework/php (Composer package php-qml/bridge),
framework/qml (Qt module placeholder), framework/skeleton (Caddyfile +
Makefile stubs), and .gitea/workflows/ci.yml. Root .gitignore covers
the build/composer/Symfony/Qt/CMake/IDE artefacts the rest of Phase 1
will produce. No bundle code, no Qt module sources, no working dev mode
yet — those land in sub-commits 2-7. Spike still in place.
