timothyandClaude Fable 5.1	4454f1adfc	docs(563): anchor the measurements to the issue, which a squash merge cannot erase ... The paragraph added a commit ago pointed at "the commit messages that ran them" as the home of the binder and `trim` mutant outcomes. A squash merge writes its own message and drops the bodies it squashes, so that pointer can go stale the moment this branch lands. The issue and its pull request survive it, and #563 is where the round-by-round measurements already are.

timothyandClaude Fable 5.1	3df98d247f	docs(563): state each binder test's mechanism instead of its mutant colour, per the amended CLAIMS rule ... `testing.mutation-claims-are-executed` was amended on main while this branch was in review (#881, merged as #914): a sentence asserting that a specific mutation reddens — or does not redden — a named test is now either a `CLAIMS` entry in `scripts/tests/mutation_manifest.py` that executes every run, or it is not written. This branch carried six such sentences and none of them can be declared: `Claim.node_id` resolves a proof to `scripts/tests/<node id>` and `run_pytest` invokes pytest, so an NUnit proof has no representation in that harness at all. Durable prose now states the mechanism each test is built on — which serializer difference, which engine branch — which a reader re-checks by reading the code rather than by trusting a remembered outcome. The record says that in one paragraph, so the limit is stated rather than papered over. The outcomes themselves are here. Re-measured 2026-09-05 on this branch's tree (the commit before this one), each mutant applied to the working tree and restored from the index between runs, tree verified clean afterwards: positive control ScriptedScheduleControllerTests Passed: 9, Failed: 0 OpenApiSerializerContractTests Passed: 4, Failed: 0 Bind<T> -> System.Text.Json with JsonSerializerDefaults.Web Failed: 2, Passed: 7 — Production_Body_Binder_Ignores_Required_Members, Production_Body_Binder_Keeps_Declared_Defaults_Over_An_Explicit_Null BodyBinderSettings = ApiJsonSettings.Create() -> new JsonSerializerSettings() Failed: 1, Passed: 8 — Production_Body_Binder_Keeps_Declared_Defaults_Over_An_Explicit_Null OpenApiSerializerContractTests RuntimeSettings -> new JsonSerializerSettings() Failed: 4, Passed: 0 — all four cases, on PascalCase keys ScriptedScheduleController AddDuration(..., request.Trim, ...) -> false Failed: 1, Passed: 8 — Committed_Script_Fixture_Produces_The_Pinned_Snapshot ScriptedScheduleController PadUntilExact(..., request.Trim, ...) -> false Failed: 1, Passed: 8 — Committed_Script_Fixture_Produces_The_Pinned_Snapshot The last one is the round-two finding closed and re-witnessed: before the fixture's pad target moved off the content boundary, that mutant left all nine green. A squash merge writes its own message, so these figures also belong in the PR description.

timothyandClaude Fable 5.1	d6e4426aa9	docs(563): retire the forward-references the supersession falsified, and trim the record to what only it says ... Two pointers still named #563 as the open reason scripted playout has no coverage. The ContentEnumeratorBuilderTests header now points at the successor record and docs/testing.md instead of the issue this branch closes. docs/decisions.md carried an orphaned fragment, "external-process pipeline remains #563's", in the residual block under ## Index -- with the pipeline now permanently outside the automated suite rather than deferred, the fragment states something false and has no recoverable subject to rewrite it around, so it goes. The record's rule gains the two things measurement settled: that ApiJsonSettings shares production's configuration and never MVC's settings object (MaxDepth 32, the two ProblemDetails converters, pinned by ApiJsonSettingsTests), and that a fixture must aim every trimming instruction between two content boundaries or that action's trim argument is witnessed by nothing. Its body loses the mutant table and the extraction paragraph, which the mechanics doc its own frontmatter points at carries verbatim; what remains is the conclusion plus the reasoning that exists nowhere else. 70 prose lines to 56, under the advisory ceiling without dropping a distinct finding.

timothyandClaude Fable 5.1	c0a70d724a	test(563): witness the Newtonsoft half of the binder claim, and narrow the prose to what reddens ... The branch asserted that binding fixture bodies through ApiJsonSettings makes "a swap to a lookalike serializer" redden. Measured, only half of that was true: replacing ScriptedScheduleControllerTests' BodyBinderSettings with a plain `new JsonSerializerSettings()` -- a Newtonsoft lookalike that has lost the production configuration -- left all 8 tests green. Only the System.Text.Json swap reddened. So the production edits the branch makes for that coupling (ErsatzTV/Serialization/ApiJsonSettings.cs and the Startup rewrite) were justified in four places by a hazard no test could see. Both halves are now real. Production_Body_Binder_Keeps_Declared_Defaults_Over_An_Explicit_Null binds `{"order": null}` and posts it to AddCollection: NullValueHandling.Ignore keeps ContentCollection.Order at its declared "shuffle" and the call is a 200, where Newtonsoft's own Include default writes the null through and AddCollection's Enum.TryParse returns a 400. That is a behaviour difference a script would see, not a settings-shape assertion, so it is not a second copy of the settings list. Mutants, run 2026-09-05 over the 9-test fixture: Bind -> System.Text.Json web defaults 2 red BodyBinderSettings -> new() 1 red (was 0 before this commit) OpenApi RuntimeSettings -> new() 4 red (write side, naming strategy) What still nothing observes is Startup.ConfigureServices itself: re-inlining the AddNewtonsoftJson lambda as a hand-copy of Apply reddens no test, because a byte-equal mirror is behaviourally indistinguishable. ApiJsonSettings removes the duplicate rather than detecting its drift, and docs/testing.md, the decision record and all four docstrings now say that instead of claiming a detector. Drift confined to ReferenceLoopHandling or the StringEnumConverter is witnessed by neither suite; that is stated rather than left implied. Also files the 401 blind spot the record had described as "tracked separately" while nothing tracked it. ersatztv#913 records the chain, verified from source: the filter is registered globally, EndpointRequiresKey fail-closes every mutating verb, ScriptedScheduleController carries no [SkipApiAuthorization], and neither ScriptedPlayoutBuilder nor entrypoint.py supplies a credential. Refs ersatztv#563 and ersatztv#913.

timothyandClaude Fable 5.1	4bd5cf9e91	docs(563): scope the required-member claim to the serializer, and name model validation as residue ... The previous commit said a body omitting a `required` member "reaches the action" in production. That overreaches what was measured: MVC adds an implicit required check for non-nullable reference types (ErsatzTV.Core.Nullable has <Nullable>enable</Nullable>, and Startup configures no ApiBehaviorOptions, so the [ApiController] automatic 400 is live), which would very likely reject that body before the action. What is measured is the SERIALIZER: Newtonsoft deserializes it to a default, System.Text.Json throws. The prose in the test, ApiJsonSettings, the record and docs/testing.md now stops there and puts MVC model validation on the uncovered-wrapper list where it belongs.

timothyandClaude Fable 5.1	16a6e2790f	test(563): bind the fixture with the production body binder, and name the wrapper that is left ... The docstring, the decision record and docs/testing.md all claimed the replay covered everything except two hops. MVC model binding was a third: production binds /api/* bodies with Newtonsoft (Startup -> AddNewtonsoftJson -> CustomContractResolver + StringEnumConverter) while the replay deserialized with System.Text.Json. Measured on this tree: for the fixture's own bodies the two agree, but for a body omitting the `required` member "collection" they diverge -- System.Text.Json throws, Newtonsoft binds Collection = null and the action runs. So the fixture's stated purpose ("field names and casing match what the HTTP body binder accepts") was asserted by nothing, and a fixture production would bind differently could still go green. Rather than only widening the residue list, bind the way production binds. The registration moves into ErsatzTV/Serialization/ApiJsonSettings.cs, Startup applies it from there, and both OpenApiSerializerContractTests (which had its own mirror of the settings) and the scripted replay now call that same function -- one definition, no copies to drift. Production_Body_Binder_Ignores_Required_Members asserts both halves of the divergence THROUGH the replay's own Bind helper, so pointing the replayer at another serializer reddens; the fixture's own bodies cannot witness that swap. The residue is now named honestly in all four places: the binding WRAPPER (input formatter, the [ApiController] automatic 400 before an action runs) is uncovered, the serializer inside it is not.

timothyandClaude Fable 5.1	0d2cd89782	docs(563): supersede the scripted-golden deferral with the in-process coverage rule ... The deferral record described ScriptedScheduleController as a "1:1 pass-through" to SchedulingEngine. It is not: an unparseable playback order is a 400, an unparseable filler kind SILENTLY degrades to FillerKind.None, an unknown build id is a 404, and the engine's no-progress InvalidOperationException is translated to a 400. Carrying that wording forward would have shipped a false statement, so the successor states a thin adapter with named mappings, each pinned by a test. - new record testing.scripted-engine-in-process-net (active, since 2026-09-05) - predecessor testing.scripted-playout-golden-deferred git mv'd to docs/decisions/archive/testing/ with frontmatter retargeted only; body prose byte-identical, so no Decisions-Edit trailer - docs/decisions.md Index line retargeted to the archive path plus a new dated line for the successor - catalog regenerated with scripts/build_decisions_catalog.py - docs/testing.md: the Golden-file nets paragraph now points at the new coverage instead of "tracked in ersatztv#563"; a new "Scripted playout coverage" section states what is covered where and what is deliberately not covered (Cli.Wrap launch, Kestrel + Startup middleware, ApiAuthorizationFilter), dated 2026-09-05; Timezone independence records the per-call TZ audit that decided which engine instructions the fixtures may use.
