# Description
Adds the pure Types-side WoT Thing Description / Thing Model to NodeSet
conversion: resolution, context, declarations, types, values,
localization, URI/format handling, bounded hashing, plus supporting
native XML codec, NodeSet alias/value helpers, RelativePathFormatter and
a JsonElement equality polyfill.
- Carrier-witness fix: a missing native event is accepted only when the
owning preserved type declares it through a `GeneratesEvent` reference
(directly or via its type/supertype chain) AND a bounded, validated
selected EventType carrier identity equals the normalized authored
native target. Native-present events get a full compare; an ambiguous
native key and a missing map stay strict; a readable document is never
archive authority.
- Support-only dependencies: additive per-instance, non-serialized
`WotDocument.IsSupportOnly(kind, name)` (ArgumentNullException guard).
The resolver marks support-only after closure; explicit selection wins;
the View builder excludes only true support-only members, so unit/actsOn
dependencies stay in the JSON. Nested controls cover inner value-only
projection under an outer value-only selection (unit kept, support-only)
versus an outer explicit SelectAll (explicit, not support-only).
- Documentation/XML comments and member-order only in commit 5c368d3a;
no logic change.
- Timeout repair on current head 6957dd46: invocation-scoped
`ArchiveDerivations` reuse removes repeated document-set derivation work
without a global cache (functional files
`WotNodeSetConverter.{Archive,ArchiveDerivations,Partitions,WoT}.cs`,
plus `WotArchiveDerivationsTests` and
`WotDocumentSetSharedValidationTests`). The original local full29
reproduction changed from 27 passed / 2 Refresh timeouts to 29 passed
with unchanged limits; official CI on this head FAILED at three
per-project time ceilings (see the evidence ledger). Temporary RF1
diagnostics were fully removed; the final tree differs from 0f7b9a09
only in the six functional files.
- Test-only net48 compile repair in commit b838907 (earlier head):
official CI on 5c368d3a was RED on the net48 build with CS1061 (see
ledger); the fix adds `using System.Threading;` and an unqualified
`CancellationTokenSource` in one test file. No production change.
Defaults: DI default document budget 256 versus the sample's explicit
1024. Corpus: canonical 540-JSON inventory; the actual manifest is 535
entries = 394 TD + 141 TM (the roles of the other 5 are not claimed).
Native Pumps assertions (9624 nodes / 339 partitions) are unchanged.
# Description
`RequestLifetime` now publishes the winning cancellation status and
terminal ownership in a single atomic state, so concurrent client
Cancel, Session close and timeout can never overwrite each other's
status or double-own the terminal transition. External token
registrations are owned by the lifetime and released on completion, and
disposal is deferred until running cancellation callbacks have finished
(no use-after-dispose of the CancellationTokenSource).
Adds regression tests: 16384-iteration race tests asserting
status/owner/callback outcomes with a finite 2 min watchdog
(`RequestLifetimeTests`, `RequestManagerTests`) and `WaitAsync`
cancellation tests (`TaskWaitAsyncTests`; the polyfill change is only 2
XML doc lines, no runtime change).
Files: `RequestLifetime.cs`, `System.Threading.Tasks.cs` (docs), and the
three test files. `StandardServer.cs` is intentionally untouched
(already on master).
