McpExtension built its middleware chain entirely internally, so a consumer had no
way to add rate limiting, audit logging or tracing to /mcp — routine on every other
Flash route. McpConfig.middleware(...) appends to the chain after the transport
guards and after whatever McpSecurity resolved to, so it composes with OAuth2
protection instead of replacing it, and never satisfies REQUIRED.
Docs: flash-ext-auth-core and flash-ext-auth-oidc both get a docs/ directory —
oidc had none at all, and its module README documented types that no longer exist.
Includes a migration table from flash-ext-oidc.
AuthMiddleware.install(ctx, config, source) now owns the annotation processor and
the flash.auth.policy key, so a second credential source gets annotation-driven
authorization without copying the wiring. The key is public: an extension that
contributes middleware can order itself around authentication.
OidcSession becomes Session in auth-core, carrying claims, an expiry and an opaque
attribute map. OpenID Connect keeps its access, id and refresh tokens in that map
under its own keys, so renewal stays its business and core has no OAuth2 vocabulary
in it. isAccessTokenExpired() becomes isExpired(), with the 30s eager-renewal
window it always had and now a test for it.
flash-ext-oidc is renamed flash-ext-auth-oidc, matching cache-core/cache-caffeine
and data-core/data-hibernate.
flash-ext-oidc has always held two things: the OpenID Connect protocol, and a
session/claims/authorization layer that is generic and was only ever fed by one
source. This splits them along Flash's own <domain>-core convention, the same
shape cache-core, data-core and view-core already use.
flash-ext-auth-core gets what never referenced the protocol — @Authenticated,
@RolesAllowed, @ScopesAllowed, ClaimsHolder, the claim matching, and the policy
compiled from annotations — under generic names: OidcUser is Claims, since it
never was more than a typed view over a claims map, and OidcAuthPolicy is
AuthPolicy. It was package-private while being the parameter type of a public
method, so the move also fixes that.
The new seam is CredentialSource: it resolves a request's claims, or rejects the
request the way its protocol says to. AuthMiddleware publishes the result and
matches roles and scopes against it. ClaimsHolder's writers stay package-private
— an implementation produces claims and core publishes them, so nothing outside
this module can put claims on a request that did not carry them.
flash-ext-oidc keeps discovery, JWKS, PKCE, the token endpoint, the login and
callback routes and the OpenAPI oauth2 contributor, and now registers
OidcCredentialSource. flash-ext-mcp still keys McpSecurity on finding that type
and not on AuthMiddleware: REQUIRED has to keep meaning "a real authorization
server is protecting this endpoint", not "something authenticates here".
The middleware key moves with the mechanism: flash.oidc.policy -> flash.auth.policy.
Breaking for consumers: imports move to dev.relism.flash.ext.auth, OidcMiddleware
becomes AuthMiddleware, ClaimsHolder.user()/get() become current()/map().
Pins the current behaviour of the role/scope matching that is about to move out
of OidcMiddleware: delimiter set for string claims, whole-entry comparison for
list claims, trimming, empty-requirement semantics under ALL vs ANY, and how a
claim path that walks into a non-map resolves. None of it is OIDC-specific and
none of it was covered directly.
- BaseViewExtension: wrap the ViewRuntimeBridge provider collision with a message
naming the real constraint (one view engine per FlashApp) instead of the generic
"duplicate provider" error.
- BaseViewExtension/JteExtension: carry registered globals across JteExtension's
immutable settings builders (templateRoot/serveStatics/staticPrefix/withStaticCors/
staticCors). addGlobal() called before any of those used to be silently dropped,
since each builder method returned a fresh instance with an empty globals list.
- Correct flash-ext-view-jte docs (README, architecture.md, model-and-globals.md):
globals merge flat with one typed @param per key, not under a global.* namespace
like Thymeleaf — the docs previously claimed the same reserved namespace for both
engines, which doesn't match JteRuntime's actual merge behavior.

Split the way flash-ext-data and flash-ext-view are: cache-core defines
Cache, CacheManager, CacheSpec and CacheStats and talks to nothing;
cache-caffeine implements them in process.
users = require(CacheManager.class).build("users", spec -> spec
.maxSize(10_000).ttl(Duration.ofMinutes(10)));
return users.get(id, repo::findById);
get(key, loader) is the only shape most code needs and the only one that is
hard to get right: the loader runs once per key across concurrent callers
rather than each racing its own. A null result stores nothing, because caching
absence is a decision rather than a default.
build(name, spec) is idempotent per name, so two handlers wanting one cache get
one cache without coordinating who creates it. Disagreeing about the spec
throws rather than resolving to whichever handler initialised first, which is a
bug that only surfaces under load.
recordStats() is opt-in — counting is two atomic increments per lookup, and a
cache nobody measures should not pay for numbers nobody reads. Unmeasured
caches return CacheStats.DISABLED rather than zeroes that look like a cold
cache.
Caffeine rather than a hand-rolled LRU: for genuinely low traffic
ConcurrentHashMap::computeIfAbsent is one line and needs no module at all, and
this exists for when that stops being true. W-TinyLFU admission, striped
counters and amortised eviction are not a weekend's work, and getting them
wrong yields a cache slower than no cache. The adapter is deliberately thin —
every method delegates, adding no wrapper, copy or locking of its own.
Caches are dropped through FlashContext.onClose, so values do not outlive the
app holding them. Invisible with one app per process; immediate under test.
flash-ext-cache-redis is designed but not built, and has docs only — no module,
no pom, no source. An empty module that builds an empty jar is dead weight in
the reactor. The docs record what changes once the cache can fail: get() must
decide whether to fall through to the loader, values need a codec,
invalidateAll needs a key prefix that becomes wire contract, and eviction stats
stop meaning anything. Those are decisions that want a real second replica to
check them against.

jobs.every(Duration.ofMinutes(5), reports::refresh);
jobs.cron("0 0 3 * * *", archive::sweep);
One daemon platform thread keeps time; every job body runs on a virtual thread,
so a slow job delays nothing but its own next run and cannot occupy the timer.
Cron expressions compile once into a bitmask per field — a long for seconds and
minutes, an int for the rest — so matching an instant is a shift and a mask
rather than a parse or a set lookup. Next-fire advances by the largest unit
that cannot match instead of ticking second by second, so a yearly expression
resolves in a few dozen iterations rather than thirty million. Five or six
fields, ranges, steps, lists, named months and weekdays, both Sunday encodings,
and the standard union semantics when both day fields are restricted. A
malformed expression throws when the job is registered, not when it would have
fired.
Overlapping runs are skipped, and deliberately not configurable: two copies of
one job at once is a bug in every case anyone has needed, and a flag would only
let it be set wrongly. A skipped run logs how long the previous one has been
going.
A throwing job is logged and keeps its schedule. scheduleAtFixedRate cancels
the task on first exception, silently — a job that dies at 3am and is never
heard from again is the failure this avoids.
Shutdown goes through FlashContext.onClose, so app.stop() drains HTTP first,
then gives running jobs a grace period before forcing them down. Nothing runs
after the app stops. The grace period is the only knob.
Known ceiling, marked in the source: schedules are per-instance, so two
replicas run every job twice. A distributed lock should not exist until there
is a second replica.

Standard jakarta.validation annotations, compiled once per type into a flat
check table. No configuration: constraints come from the annotations already on
your types, and ValidationException extends HttpException with status 422 so
the default handler renders it without this extension registering anything.
record CreateUser(@NotBlank @Size(max = 80) String name,
@Email String email,
@Min(18) int age) {}
CreateUser dto = validation.body(req, CreateUser.class);
Annotations only — Hibernate Validator's engine is deliberately absent. It
resolves constraints reflectively per call and pulls ~2 MB plus EL, which is
the per-request cost this module exists to avoid. jakarta.validation-api is
~90 KB of annotations.
The passing path allocates nothing. Constraints resolve at first use into an
opcode plus operands cached in a ClassValue, so there is no map lookup and no
lock. Fields are read through MethodHandles adapted to an exact signature —
(Object)Object for references, (Object)long for primitive integrals — so
invokeExact neither boxes nor builds the argument array Field.get and
Method.invoke allocate. Checks are a flat array walked by a tableswitch rather
than a class hierarchy behind a virtual call. @Size reads a length the object
already knows and @Email scans with indexOf, because Pattern.matcher allocates
a matcher and two int arrays per call. Messages are pre-rendered at compile
time. The violation list and the exception exist only once something fails.
@Pattern is the marked exception: its regex compiles once but matcher()
allocates per call.
Constraints are read from declared fields, so records and plain classes take
one code path — a constraint on a record component propagates to its backing
field.
Jakarta null semantics are exact: only @NotNull rejects null.
flash-ext-openapi now mirrors the same annotations into the generated schema —
minLength, maxLength, minItems, minimum, maximum, pattern, format: email and
required — via an optional jakarta.validation dependency detected at boot. A
type declares its rules once and both the validator and the published contract
read them. An explicit @Schema still wins; the bridge only fills keys nobody
set, and without the annotations on the classpath the bridge class is never
loaded.
flash-ext-jackson is optional too: validate(value) works without it, only
body(req, type) needs a codec.

HttpException carries the status the caller meant, and its own javadoc says
extensions map it to a structured response — but nothing did. Every one reached
the catch-all and came back as 500, including the 400s that RequestHelper
raises for a malformed query param and that flash-ext-jackson raises for an
unparseable body. A handler doing the documented thing produced the wrong
status.
The default handler now renders HttpException at its own status, in both dev
and prod modes, with the message JSON-escaped. Not pre-encoded like JSON_404
and JSON_500: the message is per-exception, and a path that already unwound a
stack does not need the allocation shaved.

README covers the application handle, requests and assertions, service
replacement, multi-server wiring, scope, WebSockets, configuration and the
teardown ordering.
limits.md records the seven things the harness cannot do and what to use for
each: TLS, HTTP/2, WebSocket over HTTP/2, malformed requests, response framing,
the flash core module's dependency cycle, and scoped services. Each is a
consequence of a real constraint rather than an unfinished feature, so writing
them down stops the next person rediscovering them one at a time.

Two frontend layouts, each laid out on disk inside its own application's
configure(). The harness runs that lazily at first access, so @TempDir is
populated by then and the server for whichever test is not running never boots.
Replaces three blocks of HttpRequest.newBuilder(URI.create(...)) per test with
single-line assertions. 98 to 60 code lines.

McpExtensionIntegrationTest: 10 stateless JSON-RPC calls against one server
config, so one class-scoped server replaces a boot per test. 117 to 85 code
lines.
McpExtensionSecurityTest: the four server configurations it exercises — AUTO
without oidc, REQUIRED with a derived resource identifier, REQUIRED with an
explicit one, and REQUIRED with advertised scopes — become four named servers
sharing one FakeOidcProvider, replacing eight boots and a freePort() helper.
151 to 128 code lines. The boot-rejection test still builds its app directly:
a harness whose job is to boot an app is the wrong tool for asserting that
booting fails.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Every integration test picked a port by opening ServerSocket(0), closing it and
reusing the number, which races anything else on the machine between the close
and the rebind. FlashApp.port() reports the port the listener actually bound,
so the guess is gone: 18 freePort() helpers deleted, 40 call sites now pass
port(0) and read the result back.
Two ServerSocket(0) uses remain and are correct. ConnectionRunnerTest accepts
on its socket rather than using it to pick a number. H2LoadMeasurementTest
hands its port to an external nghttpd process, which has no equivalent of
port() to read back; that one is now commented to say so.
HttpServerTlsTest's two-listener case reads both back through ports().
HttpServerTest and HttpServerConcurrencyTest also move from @BeforeEach to
@BeforeAll — every test in them is read-only against the same routes, so 11 and
3 boots respectively become 1. HttpServerConcurrencyTest's lazy-compile test
keeps building its own app, since a freshly compiled router is the thing it
tests. HttpServerTest now runs 11 tests in 0.06s.
The http2 interop suites (curl, nghttp, grpcurl, h2spec), the load measurement
and the soak test are skipped without their external binaries or system
property, so those edits are compile-verified here and exercised in CI.

beforeEach called ensureStarted(), so every FlashTest field in a class booted
for every test whether or not that test touched it — a class holding four
servers paid for four boots per test. Booting is already lazy on first access,
so the hook was only ever forcing work forward.
Neither hook starts anything now. beforeAll still records that a static field
owns the class-scoped lifecycle, which is what keeps afterEach from tearing a
class-scoped server down after the first test.
This also lets an application read @TempDir inside configure(): JUnit populates
those during instance post-processing, before the first test body but after
extension beforeEach callbacks would have fired.

First migration, chosen because it is the case that drove the harness design:
a Flash app plus a FakeOidcProvider, with tokens audience-bound to the app's
own port, so the port has to be readable after boot.
Drops the racy free-port dance, the hand-rolled HttpClient plumbing and the
per-test teardown; failures now report the response body. 120 to 106 code
lines, and what remains is tool-policy assertions rather than fixture code.
The two boot-rejection tests keep building their app directly — a harness whose
job is to boot an app is the wrong tool for asserting that booting fails — but
port(0) removes freePort() from those too.

Boots a real app on an OS-assigned port for a test class or a single test and
hands back a client pointed at it:
@RegisterExtension
static FlashTest app = FlashTest.of(new BlogApp())
.mock(UserService.class, new InMemoryUserService());
app.get("/api/users").expectStatus(200).expectBodyContains("alice");
A field rather than an annotation, because annotation values are compile-time
constants and so could never express a second server wired from the first —
FlashTest.of(new BlogApp(auth.baseUri())). Startup is lazy, so reading
baseUri() boots that server on the spot and declaration order does the wiring,
with no dependence on JUnit's extension ordering. A static field boots once per
class, a non-static field once per test; that is stock JUnit field semantics
rather than an option to configure.
Runs against a real loopback port instead of dispatching in-process. An
in-process dispatcher would be a third copy of the routing/handler/exception
sequence that Http1Connection and Http2StreamDispatcher already duplicate, kept
in sync by hand, and it would let a test pass while the status line,
content-length or HPACK encoding was broken.
mock() installs overrides as the last extension, after everything the
application and its extensions declare, so a fake always wins. Any object is
accepted, so a hand-written fake and a Mockito mock are equally welcome and
this module depends on no mocking library — only flash and junit-jupiter-api.
Teardown cancels the client before stopping the server: HttpClient holds
keep-alive sockets open and ServerLifecycle.stop() spins until the last one
closes, so the default 15s drain would otherwise be paid on every test class.
shutdownNow rather than close(), which blocks until every operation completes
and would hang on a leaked WebSocket.
Lives at the top level, not under flash-extensions/, which holds things you
install() onto an app; this carries junit-jupiter-api at compile scope and
nothing installable should.

Four small seams, each useful on its own, that together make a Flash app
testable without hand-rolled scaffolding.
- ServerHandle/ServerLifecycle/FlashApp gain port()/ports(). Listeners already
bind in the FlashApp constructor, so port(0) resolved to a real port that
nothing could read back; every integration test worked around this by
opening a ServerSocket(0), closing it and reusing the number, which races
anything else on the machine.
- FlashContext.override() replaces a binding instead of rejecting it. The
duplicate-is-an-error rule stays everywhere else; this is the single
deliberate exception, for swapping a service out in tests. A replacement is
logged at INFO so misuse in production is visible.
- FlashApplication + FlashApp.apply() name an application independently of the
port it runs on, so the same one can be booted twice. It takes FlashApp
rather than FlashRegistrar because ws() and mount() live there. Being a
functional interface, a lambda and a named class are the same thing.
- FlashContext.onClose() runs cleanup at stop(), children first and then in
reverse registration order. stop() previously closed sockets and the
executor and never touched the service graph, so a pooled DataSource was
only ever released by JVM exit — invisible with one app per process, a leak
per test class once a suite boots and stops many.

FlashRegistrar#any() registers a handler under every HTTP method for
verb-indifferent handlers (e.g. a reverse proxy). OpenApiExtension now warns
when a class-based handler has no @ApiOperation instead of silently omitting
it from the spec. AbstractRouter's default production exception handler now
logs unhandled exceptions server-side instead of only returning a JSON 500.

maven.relism.dev is down. fpr-core's source (FastPathRouter) now publishes
to Gitea's own Maven registry via its own publish-maven.yml, same pattern
this project already uses for itself — point <repositories> there and bump
the pinned fpr-core version to the first build actually published there
(1.1.0-36216cd). Full reactor build + test suite green against the new
resolution.

Http2ResponseWriter.streamBody (a streaming response's InputStream, driven
across startFlowControlled/resume as flow-control windows allow) was never
closed anywhere -- not on clean EOF, not on a write failure, not when the
stream is abandoned (RST_STREAM from the peer, connection teardown). Same
bug Http1ResponseWriter had before cf16be0, just never given the same fix: a
handler stream that releases a held resource (a pooled backend connection,
for a reverse proxy) from close() leaks it under any real amount of stream
resets or aborted connections.
- appendData closes streamBody once `end` is reached (clean completion) and
on any IOException from the read itself, mirroring Http1ResponseWriter's
relayAndClose/writeChunkedAndClose reasoning.
- New Http2ResponseWriter#abort(), called from Http2Stream#cancel() --
symmetric with that method's existing http2Body.cancel() for the inbound
leg, now covering the outbound one too. cancel() is the single hook every
abandoned-stream path (RST_STREAM handling and connection teardown in
Http2Connection, plus Http2StreamDispatcher) already goes through, so this
covers every abort case without adding a new one.
closeStreamBodyQuietly() is idempotent (nulls streamBody after closing), so
the appendData and abort() close paths can't double-close or race.
Four new Http2ResponseWriterTest cases: normal completion in one call,
completion across a resume() (multiple flow-control windows), abort() while
still streaming, and abort() as a no-op on a non-streaming response. 697/697
flash-module tests green.

Claude-Session: https://claude.ai/code/session_011LLwcyHUnbApCrY33gvgoa
WebSocketSession.close(int) hand-wrote a raw, always-unmasked 4-byte CLOSE
frame, bypassing writeFrame's maskOutgoing handling that sendText/send/
sendPong already go through correctly. A client-mode session (maskOutgoing
true — WS-client usage, e.g. Pathway's UpstreamWebSocketConnector relaying a
proxied client's close to a backend) therefore sent an RFC-6455-invalid
unmasked frame.
This was latent until this same HTTP/2 branch's readFrame rewrite added the
receive-side masking check RFC 6455 §5.1 requires: a strict peer now rejects
the malformed frame with WebSocketProtocolException("client frame must be
masked") before ever exposing it as a CLOSE, silently dropping the close
instead of relaying it — reproduced end to end via Pathway's
ProxyWebSocketIntegrationTest.clientCloseIsForwardedToTheBackend.
close(int) now builds its 2-byte payload and calls the same writeFrame path
every other outgoing frame uses, so masking (or not) follows maskOutgoing
automatically. Existing server-mode close_setsClosedAndWritesFrame is
unchanged (byte-for-byte identical output — no mask bit, no key). Added
close_masksWhenActingAsClient (mirrors the existing sendText coverage) and a
round-trip regression, readFrame_acceptsCloseFrameWrittenByAClientSession,
that reproduces the actual bug: a client session's close() output fed
straight into a server session's readFrame().

HttpProxy and Http2Client (719 LOC) shipped a reverse-proxy adapter and outbound HTTP/2
client from flash core with zero callers anywhere in the server itself — only each
other and their own tests. An HTTP/1.1+2 server framework has no business bundling an
outbound client; that capability belongs in its own flash-extensions/flash-ext-*
module if/when it's needed. Removed, along with the now-dead src/bench load driver
that depended on Http2Client (no replacement client written here — flagged as
follow-up work, not silently dropped).
docs/http2/ had accumulated core, cross-protocol documentation alongside genuine
HTTP/2-protocol internals: HTTP1-HARDENING, TRANSPORT, MESSAGE-MODEL,
TRAILERS-AND-STREAMING and BYTES all describe machinery HTTP/1.1 and HTTP/2 share, not
HTTP/2 specifically. Moved to a new docs/core/, leaving docs/http2/ to the protocol
layers, wire internals and operational docs that are actually HTTP/2-specific.
CLEARTEXT-AND-PROXY.md renamed to CLEARTEXT.md and its now-removed upstream-client
section cut, matching the source removal above.
README.md: removed the "HTTP/2 upstream proxy" section (documented the deleted
HttpProxy/Http2Client), the flash-bench module row and build command (not a module
that exists in this repo), and fixed every doc link to the new docs/core/ paths.
Added the new FlashConfiguration.maxConnections field to the configuration reference.
src/bench/ (a load-test harness distinct from the JMH suite, not wired into any Maven
profile or CI) is committed here for the first time.
Targeted stress testing under this branch's HTTP/2 work surfaced four independent
production bugs, each verified with a before/after load test and a regression test:
- Http2Limits.MAX_STREAMS_CREATED_PER_INTERVAL (400/10s) rejected legitimate
high-concurrency HTTP/2 clients as if they were CVE-2023-44487 rapid-reset abuse —
h2load's default pattern alone triggered 40-92% request failure. Raised to 100,000,
matching MAX_STREAMS_PER_CONNECTION's existing lifetime budget; the RST_STREAM-rate
counter remains the precise defence against the actual attack signature.
- Flash had no connection-admission control anywhere: AcceptLoop accepted every TCP
connection unconditionally, so a connection flood (h2load -c 400) ran the JVM out of
heap and crashed with OutOfMemoryError, killing even unrelated daemon threads.
TransportLimits.defaultMaxConnections() auto-scales a cap from Runtime.maxMemory();
ConnectionRunner.accept() enforces it before any per-connection state (TLS handshake
included) is created. Verified surviving 42x the admission limit under both cleartext
and TLS load with bounded RSS.
- Http1ResponseWriter never closed a handler's streaming response body on a write
failure (e.g. the client disconnecting mid-transfer) — only on a clean EOF. A handler
whose stream releases a held resource (a pooled backend connection, for a reverse
proxy) from close() leaks it under any real amount of client disconnects. Now closed
on every exit path, matching InputStream#close()'s own idempotency contract.
- Http2StreamState.transition() called the enum's values() every state transition;
values() clones a fresh array on every call. Cached once, removing ~10.76% of
allocations measured live under load.
695 -> 698 tests (three new regression tests), all passing.
Pools Request/RequestBody/RequestLine/Response per connection (EX-20..EX-24),
following the same reset()/dev-mode-guard idiom Http1HeaderMap already used.
HeaderMap splits into HeaderView (interface) + Http1HeaderMap (impl, DEC-22).
Response gains byte-level structured headers, PreEncodedHeader, and
ResponseSerializer as the single source of truth for a response's header
sequence, consumed by Http1ResponseWriter's single-bulk-write rewrite (EX-27).
ByteTemplate gets O(1) slot lookup plus a buffer-writing overload (EX-28).
Multipart audited: three resource-exhaustion gaps found and fixed — unbounded
buffered part size, part count, and per-part header parsing (EX-38..EX-40) —
and boundary length confirmed already bounded (EX-41).
Re-measuring RequestPipelineBenchmark after the pooling work surfaced one more
per-request allocation underneath it (RequestParser building fresh
RequestByteViews every call) and, while checking the phase's own DoD text, an
unbounded Response.header(...) loop hazard neither had a limit — both fixed
(EX-42, EX-43). The h1 zero-alloc contract now holds: parseAndRoute measures
0.008 B/op (JMH noise floor), down from Phase 4's 120.008 B/op (DEC-20, DEC-23).
MESSAGE-MODEL.md records the pooling model; README gains an "Object lifetime"
section documenting the do-not-retain-past-the-handler contract. 503/503 tests
green.

Implements HTTP/2 frame reading, validation, and writing: FrameType (the
10 RFC 9113 types + per-type validation descriptor), FrameFlags (with
the deliberate END_STREAM/ACK bit collision documented), FrameHeader (a
flyweight, never allocated per frame), Http2FrameReader (length-prefixed
reader over BufferedByteSource, mirroring RequestParser's buffer/
compaction discipline), FrameValidator (table-driven, specific RFC error
code per violation -- not a uniform code per type), Padding (RFC 9113
6.1/6.2), and FrameWriteBuffer (beginFrame/endFrame length back-patching
over Phase 4's ByteWriter).
All 10 frame types round-trip correctly; every RFC-mandated rejection
has its own test asserting the specific error code; the reader is
fuzz-tested against 10,000,000 random inputs (~14s). The zero-alloc
contract is measured, not asserted: reading + validating + consuming a
frame is 0.002 B/op, writing one is ~10^-4 B/op -- both indistinguishable
from zero (DEC-21).
Found and fixed EX-37 while writing Http2FrameReaderTest: BufferedByteSource's
deadline mechanism (EX-07's actual fix) NPE'd against a null socket, which
every isolated unit test in this codebase uses -- it had zero dedicated
test coverage of its own. Fixed to treat a null socket as "no OS-level
timeout to bound" rather than a misuse, and given BufferedByteSourceTest,
which did not exist before.
449/449 tests green, both with and without -Pjmh.

Builds dev.relism.flash.bytes: ByteScan (scanning/comparison/hashing,
scalar + SWAR, property-tested against each other on every boundary and
20,000 random fuzz trials each), ArrayBackedByteView/SegmentedByteView
capability hierarchy, PooledSlice/SlicePool, ByteWriter, Pairs.
Cashes in the allocation and scanning wins the existing code left on the
table: EX-04 (word-at-a-time router matching, verified directly against
fpr-core's own ByteCompare), EX-05 (pooled views replacing per-call
anonymous ByteView allocations in HeaderMap/QueryParams/PathParams),
EX-09 (HeaderMap index built once per reset() instead of rescanning per
lookup), EX-19 (reusable PathParams on the router's per-connection
scratch), EX-25/EX-26 (single-allocation String construction), EX-33
(SWAR header-terminator scan in RequestParser).
Also closes EX-06's router half, missing from this phase's own EX-item
list in the plan (same class of omission DEC-12 recorded for Phase 1):
FastPathRouterImpl/FastPathWsRouterImpl's ThreadLocals (unbounded under
one-virtual-thread-per-connection) are replaced by an opaque,
caller-owned per-connection scratch object (AbstractRouter#newScratch),
not by extending ConnectionScratch as its own Javadoc originally assumed
-- that would have created transport's first dependency on routing in
the reverse direction. Full rationale in DEC-19.
Every optimization is measured, not asserted (DEC-20): SWAR scan 35.4%
faster than scalar, kept; EX-04's word-path 32.1% faster than
byte-at-a-time at the mechanism level, kept for its real future
consumers even though today's router doesn't yet route through it
(MethodPathByteView stays deliberately non-array-backed, per the plan's
own text). Router matching itself is ~0 B/op including parametric
routes. The full h1 pipeline is not literally 0 B/op yet -- 120 B/op is
Request/RequestBody/RequestLine construction, honestly attributed to
Phase 6's explicit scope rather than hidden.
395/395 tests green, both with and without -Pjmh.

Implements the connection-level serialized frame writer per the plan's
go/no-go gate: tryLock() fast path with an intrusive Vyukov-style MPSC
fallback under contention, ReentrantLock throughout (never synchronized),
and a scan-based write-timeout reaper.
All four gate criteria met and measured: N=1 0 B/op and 42.6 ns overhead
(<=50 ns budget); N=64 65.5% throughput retention (>=60%) and 11.8-14.2 us
p999 (<1 ms); no carrier pinning; stress test 10,000/10,000 green across
1000 iterations x 5 concurrency levels x 2 scheduler configs. Compared
against plain-lock and dedicated-thread designs with real benchmark
numbers, not assertion. Full methodology and results in WRITER.md, DEC-09.
Also fixes a real regression found while resuming this work: the JMH
benchmark broke plain `mvn test` (no -Pjmh) because it lived in
src/test/java, which Surefire's test discovery loads regardless of
whether a class is ultimately selected as a test. Moved to a dedicated
src/jmh/java source root registered only under the jmh profile
(build-helper-maven-plugin), per DEC-17.

Breaks HttpServer (563 lines, eleven responsibilities) into named,
single-purpose components and introduces the ConnectionProtocol seam
HTTP/2 plugs into starting Phase 8, per
flash/docs/http2/IMPLEMENTATION-PLAN.md Phase 2.
New packages:
- dev.relism.flash.transport: TransportFactory (composition root, EX-34),
ListenerBinder, BoundListener, TransportTuning, AcceptLoop,
ConnectionRunner (per-connection setup/teardown), ConnectionProtocol
(the h1/h2 seam), ConnectionContext, ConnectionScratch + ScratchPool
(EX-06), ServerLifecycle (implements ServerHandle; start/stop/graceful
shutdown, EX-32).
- dev.relism.flash.http1: Http1Connection (the keep-alive request loop,
implements ConnectionProtocol), Http1ResponseWriter, Http1KeepAlive
(the shared Connection-header token-list scanner, EX-13).
- dev.relism.flash.websocket additions: WebSocketUpgrade (detection +
handshake), WebSocketLoop (session loop), WebSocketProtocolException.
Existing-code defects fixed (EX-nn):
- EX-01: WebSocketSession's two blocking-write sites use ReentrantLock
instead of synchronized (out) -- a virtual thread blocking inside
synchronized pins its carrier platform thread on Java 21.
- EX-06: HttpServer's three ThreadLocals (SHA1, LONG_BUF,
STREAM_RELAY_BUFFER) replaced by ConnectionScratch, pooled via
ScratchPool instead of one-per-virtual-thread (i.e. one-per-connection)
growth. The router's ThreadLocals are deliberately deferred to Phase 4
per this EX item's own phasing -- see DEC-15 for the plan-wording fix.
- EX-11: WebSocketSession.readFrame's extended-length and mask-key bytes
are now read in a single bounded readFully instead of one at a time.
- EX-12: full RFC 6455 frame validation -- continuation-frame
reassembly, mandatory masking-direction enforcement, opcode
validation, control-frame constraints (not fragmented, <=125 bytes),
and WebSocketProtocolException carrying the correct close code (1002
protocol error, 1009 message too big).
- EX-13: Connection header token-list scanning shared between the
keep-alive decision and the WebSocket upgrade check.
- EX-14: HEAD responses report Content-Length but write no body.
- EX-15: Content-Type omitted when empty; Content-Length and the body
omitted entirely for 204/304/1xx responses.
- EX-16: Date header (dev.relism.flash.http.DateHeader), refreshed once
per second by a shared daemon thread; FlashConfiguration.sendDate.
- EX-32: two-stage graceful shutdown -- stop accepting, force
Connection: close on the response an in-flight handler is still
producing (re-checked after the handler runs, not just before
dispatch, so a shutdown beginning mid-handler is still honoured),
drain up to shutdownDrainTimeoutMs, then force-close.
- EX-34: ServerHandle.create delegates to TransportFactory instead of
constructing HttpServer directly.
Two plan corrections recorded: DEC-15 (Phase 2's "no ThreadLocal
anywhere" DoD line contradicted EX-06's own multi-phase assignment --
corrected to match the registry) and DEC-16 (no separate
WebSocketFrameCodec class this phase; the EX-11/EX-12 fixes stay inside
WebSocketSession, which is one cohesive state machine under R6's own
carve-out -- revisit at Phase 15 if RFC 8441 needs the decoupling for
real).
HttpServer.java deleted.
311/311 tests green (flash module), run three times for stability of
the wall-clock-based timeout/shutdown tests. Whole-repo build green.
h1 benchmark regression check remains unverified in the plan's DoD (no
JMH harness until Phase 3, same caveat as Phase 1).

Fixes the request-smuggling and resource-exhaustion debt in the existing
HTTP/1.1 parser, and adds the ALPN/h2c-preface negotiation seam so a
connection's protocol is decided once, before any request is parsed, per
flash/docs/http2/IMPLEMENTATION-PLAN.md Phase 1.
Existing-code defects fixed (EX-nn):
- EX-02: reject Content-Length + Transfer-Encoding together (RFC 9112 6.1
CL.TE/TE.CL smuggling), and conflicting duplicate Content-Length values.
- EX-03: strict, overflow-safe Content-Length parsing, replacing a parser
that silently skipped non-digit bytes ("5abc" -> 5, "-1" -> 1).
- EX-07: header-read / idle-keep-alive / body-read timeouts enforced by an
absolute deadline (dev.relism.flash.transport.BufferedByteSource), not
merely Socket#setSoTimeout, which never trips against a peer trickling
one byte per read within the window.
- EX-08: header count / name length / value length / request-line length
bounds (Http1Limits), 431 on violation.
- EX-10: ChunkedInputStream now reads through BufferedByteSource instead
of the raw unbuffered socket stream, and the header-parser's read-ahead
bytes are handed over via a zero-copy prependOnce() instead of a
SequenceInputStream/ByteArrayInputStream pair.
- EX-17: HttpStatus's status-code bound is computed from values() instead
of a hand-maintained constant that silently threw
ArrayIndexOutOfBoundsException when a code above it was added; added
421, 431, 505, 507, 511 and others HTTP/2 and this hardening need.
- EX-18: bare-CR desync and obsolete line folding rejected.
- EX-30: the TLS handshake is forced explicitly, under a timeout, before
any protocol decision -- SSLSocket#getApplicationProtocol() returned
null until the handshake had run, and nothing previously forced it.
- EX-31: TLS 1.2 cipher suites on the RFC 9113 Appendix A blocklist are
filtered out of a listener's enabled set whenever it offers h2 via ALPN.
- EX-35 (found in this phase): Transfer-Encoding values listing multiple
codings ("gzip, chunked") were silently treated as not chunked at all,
corrupting the message boundary -- only the whole value was compared.
- EX-36 (found in this phase): a header line with no ':' was silently
skipped instead of rejected.
New:
- dev.relism.flash.transport.BufferedByteSource: the single buffered,
deadline-aware, peekable view over a connection's inbound bytes.
- dev.relism.flash.transport.ProtocolNegotiator/NegotiatedProtocol: ALPN
and h2c prior-knowledge detection. In this phase an H2 result is always
closed cleanly -- there is no Http2Connection to hand off to until
Phase 8. FlashConfiguration.http2Enabled gates the h2c preface peek.
- dev.relism.flash.exceptions.MalformedRequestException: a typed,
status-carrying rejection distinct from HttpException, caught at the
parse site so a malformed request never reaches the handler chain or
the user's exception handler, and the connection is always closed.
Two small plan-document corrections recorded as DEC-12 (Phase 1's Files
list omitted BufferedByteSource.java and MalformedRequestException.java;
the request-line-length check description pointed at the wrong offset).
DEC-13/DEC-14 record the deadline and exception-hierarchy designs.
277/277 tests green (flash module), run twice for stability of the new
wall-clock-based HttpServerTimeoutTest cases. Whole-repo build green.
h1 benchmark regression check is left unverified in the plan's DoD: no
JMH harness exists yet (Phase 3 deliverable).

Establishes the package layout, limits/error model and decision-log
convention that every later HTTP/2 phase depends on, per
flash/docs/http2/IMPLEMENTATION-PLAN.md Phase 0.
- dev.relism.flash.h2: package-info (architecture overview), Http2ErrorCode
(the 14 RFC 9113 §7 codes with precomputed 4-byte wire encodings),
Http2Exception (connection error -> GOAWAY) and Http2StreamException
(stream error -> RST_STREAM), neither extending IOException, both with
stack-trace capture disabled on the hot rejection path.
- Http2Limits: every bound Phase 0 requires (concurrent streams, frame
size, header list size, CONTINUATION/reset/settings/ping rate bounds,
flow-control windows, HPACK table size/string length, assembly and idle
timeouts), each documented with the attack or RFC clause it addresses.
- dev.relism.flash.http.Http1Limits: the h1 bounds needed by EX-03 (strict
Content-Length) and EX-08 (header count/size limits).
- flash/docs/http2/DECISIONS.md seeded with DEC-01..DEC-11 (the ten
decisions implied by the plan itself, plus DEC-11 recording that commits
keep scope `core` rather than adding `h2` to AGENTS.md).
- flash/docs/http2/IMPLEMENTATION-PLAN.md: added the Progress Ledger
(tracks phase status across sessions) and checked off Phase 0's DoD.
19 new tests, full flash module suite green (226/226).

The three data modules' docs were in Italian, so the synchronization contract
added in the previous commit went in as Italian too, to match its file. English
is the project's language for docs, comments and READMEs alike, and a file half
in each is worse than either — so all three are translated, not just the new
section.
Content is otherwise unchanged, except the "synchronizations run on
commit/rollback" line in the two backend READMEs, which was vague before and is
now accurate about which hook sees the session/connection still bound, pointing
at flash-ext-data-core's README for the full contract.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
beforeCommit(boolean) has been part of the TxSynchronization API from the
start and was invoked by nothing, in either manager — anyone implementing it
got silence, the same failure class as the dropped afterCommit callbacks in
the previous commit. Left out of that one because fixing it is a design
decision rather than a restored behaviour; this is that decision, written
down.
It now runs immediately before the real commit, with the transaction still
active and its session/connection still bound, which is the whole reason to
have a hook on this side of the commit: it can still write through the same
resource and land in the same atomic unit. Skipped when the transaction is
already rollback-only, since there is no commit to precede.
Throwing from it vetoes the commit: the transaction rolls back, the surviving
callbacks hear ROLLED_BACK, and the exception propagates. Without that, a hook
running before the commit would be strictly less useful than one running
after. A commit that fails on its own now takes the same path instead of
completing silently with no callback at all, and a rollback that also fails is
attached as a suppressed exception rather than replacing the one that explains
the failure.
Documented on the interface itself and in flash-ext-data-core/docs/README.md:
which hook sits on which side of the commit, what each may still touch, what
throwing does, and the per-transaction scoping rule from the previous commit.
Tests: 6 more (3 per manager) — runs inside the transaction with the resource
still bound, receives the read-only flag, skipped on a rollback-only
transaction, and vetoes the commit when it throws. 37 across the two managers
now, all green, reactor verify passes the 80% Jacoco gate.

Two defects in the same mechanism, both silent.
1. HibernateTxManager#commit fired synchronizations *after* its finally block,
where cleanupIfIdle() had already called ResourceRegistry.cleanup() and
removed the ThreadLocal list holding them. fireSynchronizations() then read
a freshly initialized empty list and did nothing. No afterCommit callback
had ever run on the Hibernate path: no exception, no log, just silence.
rollback() twenty lines below had the order right, which is what makes this
an ordering slip rather than a design choice.
Found in production, from the far end: an admin write landed in Postgres
while the in-memory cache it was registered to refresh never heard about it,
so the change only took effect when the process restarted and re-read the
database at boot.
2. Synchronizations were a single flat per-thread list, fired from index 0 by
whichever transaction completed first. A REQUIRES_NEW inner transaction
therefore fired the *suspended* outer transaction's callbacks too — early,
with the inner transaction's outcome, for a transaction that might still
roll back. Each new transaction now records how many synchronizations were
already registered when it began, and fires only its own tail.
Both managers get the fix and the same callback ordering: unbind the session or
connection first, so a callback that opens its own transaction (a cache reload,
an outbox drain) gets a fresh one instead of joining the transaction that just
committed, then fire, then clean up.
Also fixes JdbcTxStatus rejecting a null connection, which turned the two
propagations that deliberately produce a connectionless status — SUPPORTS with
no active transaction, and NOT_SUPPORTED — into an NPE inside begin(). The
Hibernate manager always allowed it, and resource() already reports the real
mistake with a message that names it.
Tests: 16 new across the two managers, kept deliberately parallel since the two
are interchangeable behind TxManager — synchronization firing, ordering,
per-transaction scoping, callbacks opening their own transaction, and the
previously untested SUPPORTS/NOT_SUPPORTED/MANDATORY propagations. Nothing
covered afterCommit before, which is how both defects shipped.

Its maven-deploy-plugin was configured with <skip>true</skip>, so the
first successful publish-maven.yml run deployed flash-parent, flash,
and every flash-ext-* jar to Gitea's Maven registry, but not
flash-extensions itself — the pom-packaging aggregator every
flash-ext-* submodule's effective POM inherits from via <parent>.
Remote consumers (Pathway's Docker build, resolving flash-ext-* from
the registry instead of a local ~/.m2 install) couldn't resolve that
parent POM and failed with "artifacts could not be resolved:
flash-extensions:pom (absent)".

Root cause of the persistent 401s found: Gitea's own per-job GITEA_TOKEN
cannot publish to any package registry at all — a known, still-
unimplemented limitation (go-gitea/gitea#23642), not a settings.xml
auth-format issue as first assumed. Confirmed by testing: GITEA_TOKEN
authenticated fine against the plain API but every registry write
endpoint rejected it regardless of scope or header style.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Basic auth didn't fix it either — same 401 as the httpHeaders form.
Before guessing again: confirm GITEA_TOKEN actually reaches this step
non-empty, and check whether it authenticates against the plain API at
all (both header styles), independent of Maven/wagon-http.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Still 401 after granting packages:write — the httpHeaders form from
Gitea's docs is honored by Maven's resolver (dependency reads) but
apparently not reliably by the wagon-http provider maven-deploy-plugin
uploads through, which deployed unauthenticated. Basic auth is
wagon-http's oldest, always-supported path.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Deploy failed with 401 Unauthorized: this repo's default Actions token
permission mode is Restricted (read-only on packages, not Permissive),
so the auto-provided GITEA_TOKEN couldn't push to the Maven registry
without explicitly requesting write access.

actions/checkout@v4 is a Node-based action; the maven:3.9-eclipse-temurin-21
container it was running in has no Node, so it failed with "node: executable

The "org" runner label is scoped to the Pixel-Services organization —
Flash5 lives under the separate Relism account, which can only reach
the global runner (labels ubuntu-latest/ubuntu-24.04/ubuntu-22.04).
This job just runs Maven inside a container, no Docker access needed,
so ubuntu-latest is a fine fit.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The org's Gitea Actions runner is registered under the label "org" —

Lets Pathway (and other consumers) resolve dev.relism:flash from Gitea's
Maven registry instead of requiring a local `mvn install`. Every push
stamps all modules with a commit-scoped version (2.1.0-<short-sha>) before
deploying, since Gitea's registry won't let a build overwrite an existing
name+version.

Data/RepositoryFactory/HibernateData give applications one cached,
stateless entry point for repositories per entity type instead of
per-request instantiation, with write()/afterCommit() replacing manual
transaction+reload choreography.
McpConfig.rolesClaimPath is removed - MCP now derives the claim path
from OidcMiddleware.rolesClaimPath() so applications never duplicate
the roles-claim config between OIDC and MCP. McpPackageScanner is
rebuilt on the shared PackageScanner.discover(packageName) primitive,
doing only McpTool/McpResource/McpPrompt classification itself.

- TlsConfig.applicationProtocols(String...) sets the listener's negotiable
ALPN protocol list via SSLParameters, inherited by every accepted socket
like clientAuth — works on both keystore() and ofContext(), untouched
unless called. Enables TLS-ALPN-01 (RFC 8737) style on-demand cert
issuance: a custom KeyManager can read the already-resolved protocol via
engine/socket getHandshakeApplicationProtocol() inside
chooseEngineServerAlias/chooseServerAlias, since ALPN is resolved during
ClientHello/ServerHello, always before Certificate production.
- Request gains isSecure()/sslSession(), threaded through RequestParser from
the accepted SSLSocket exactly like remoteAddress() — reference-only,
zero per-request allocation. sslSession() defers to SSLSocket#getSession()
lazily, so it's a cached-field read (handshake already completed by the
time a handler can call it), never a forced handshake.
- WebSocketSession.isSecure()/sslSession() delegate to the upgrading
Request rather than tracking the socket a second time.
- Documents TLS end-to-end in README.md (listeners, TlsConfig, SNI, ALPN,
mTLS, Request/WebSocketSession accessors).

Flash can now serve HTTPS and WSS, on one or many listeners per app:
- FlashConfiguration gains an optional `tls` field for the single default
listener, and a `listeners` list for apps that bind multiple ports (each
independently plain or TLS).
- New dev.relism.flash.tls package: TlsConfig.keystore(path, password) builds
an SSLContext from a PKCS12/JKS keystore, with SNI-based certificate
selection for free when the keystore holds more than one alias (matched by
SAN/CN, pure JDK APIs). TlsConfig.ofContext(sslContext) is a full escape
hatch — Flash never calls setSSLParameters on that path, so caller-set
protocols/cipher suites/ALPN survive untouched. TlsConfig.clientAuth(...)
adds optional/required mTLS on either path.
- HttpServer moves from a single ServerSocket to a list of bound listeners;
the per-request hot path (RequestParser, routing, response writing) is
untouched — TLS only changes which bytes come out of accept(), so WSS needs
no separate code path from WS.
- process()'s catch is widened to log non-IOException failures (e.g. a
misbehaving custom KeyManager/TrustManager on the ofContext path) instead
of swallowing them silently; the failure was already isolated to the one
connection via the existing try-with-resources/executor-submission
boundary — this only fixes the missing log line.
- Fixes a pre-existing gap where FlashConfiguration#host was accepted but
never used to bind (listeners always bound to the wildcard address).

- WebSocketSession supports client-mode outgoing frame masking (RFC 6455) via
in-place XOR, reusing the unmask routine already used for inbound frames.
- HeaderMap gains an allocation-free forEach(HeaderConsumer) for callers that
must handle an open-ended set of header names (e.g. proxying).
- HttpServer relays streaming/chunked response bodies through a shared
per-connection ThreadLocal buffer instead of relying on InputStream#transferTo
(which allocates internally) or a fresh byte[8192] per chunked write.
