- Around line 40-50: Add a test case alongside the existing large-payload test
for a payload created with 'x'.repeat(20_000); render SpanPayloadView, assert
the “Rendering payload” loader appears initially, then wait for it to disappear
and verify the payload renders.
In
`@web/packages/studio/src/components/IntakeDetail/IntakeComponents/SpanPayloadView.tsx`:
- Around line 27-35: Update the JSON payload parsing logic in SpanPayloadView so
every non-empty trimmed value reaches JSON.parse, allowing valid scalar payloads
such as booleans, null, strings, and numbers to produce the formatted JSON view.
Preserve the null result for empty or invalid input, and extend the relevant
tests with scalar JSON cases.
- Around line 70-76: Update the selection state in SpanPayloadView to include
the originating span.span_id and payload role (input or output), and only reuse
the stored format when both match the current span and role; otherwise derive
the default format again. Add a regression test covering two spans with
identical input or output text to verify their format selections remain
independent.
- Around line 195-210: Update the deferred-render state in SpanPayloadView so
payload changes from small to large reset showPayload before CodeSnippet or
MarkdownContent mounts; track a signature including text and resolved in the
effect/state logic, and add a regression test covering the small-to-large
rerender transition.

Span Input/Output payloads rendered one fixed way, which made JSON payloads hard to scan and markdown payloads render as escaped text. Replace SpanPayloadBlock with SpanPayloadView, which renders a payload as verbatim text, rendered markdown, or pretty-printed JSON, plus a SpanPayloadFormatToggle for the section trigger. The two share state through useSpanPayloadFormat, called in SpanMetadataAccordions because the toggle renders in slotEnd while the payload renders in slotContent. Types and helpers sit in spanPayloadFormat, so each module exports one kind of thing. Payloads open in json when they parse as JSON and raw otherwise, so the common case needs no click. The toggle hides itself for empty payloads, disables json (with a tooltip) for payloads that are not JSON, opens a collapsed section on selection, and scopes the choice to the payload it was made for so another span re-derives the default. The json view re-indents the payload text with jsonc-parser rather than round-tripping it through JSON.stringify(JSON.parse(...)), which routes every number through a float64: an int64 span id such as 9007199254740993 rendered as 9007199254740992, 1.0 as 1, and duplicate keys collapsed to the last. Values are never converted, so the view is lossless. jsonc-parser's own applyEdits is quadratic (~6s for a 585KB payload), so the edits it produces are applied in a single pass. Payloads at or above 20,000 characters paint a spinner for one frame and skip Shiki highlighting so the full text always appears. Deferral is decided during render, since an effect runs only after a commit has already mounted the renderer with the new payload. CodeSnippet keeps highlighted markup in state and never clears it, so switching from json to raw left the pretty-printed markup on screen. Key CodeSnippet on the language it is given so it remounts with clean state on every format change. react-markdown and its remark chain are ~100KB for a format most readers never select, so the markdown renderer loads on demand and Suspense falls back to the same spinner the large-payload path already shows.

Replaces the jsonc-parser source re-indenting with JSON source text access, dropping the dependency. Parse with a reviver that re-emits each number as the literal it was parsed from, via JSON.rawJSON and the reviver's context.source, then pretty-print as before. Integers past 2^53 such as an int64 span id, along with 1.0, 1e2, and -0, survive unchanged. No feature detection: engines without JSON source text access (before Chrome 114, Firefox 135, Safari 18.4) pass no context, so the reviver falls through to the parsed value and the view degrades to the reformatted numbers. TypeScript 6.0.3 declares neither API, so both are typed locally. This gives up one case jsonc-parser covered: a payload repeating a key keeps only the last, since the object is built before any reviver runs. Noted on parseJsonPayload, with raw as the exact view, and its test is removed.

SpanPayloadView owned the spinner placeholder it renders in two places, which left two components in one module. Give it its own file, which also drops Flex and Spinner from the view's imports. Also raise the timeout on the two assertions that wait for the markdown renderer. It arrives through a dynamic import, and on a cold module cache that can outlast findBy's 1s default, so a fresh checkout could fail the suite where a warm one passed.

What
Span Input/Output payloads rendered one fixed way, which made JSON payloads hard to scan and markdown payloads render as escaped text.
This replaces
SpanPayloadBlockwithSpanPayloadView, which renders a payload in one of three formats —raw(verbatim),md(rendered markdown), orjson(pretty-printed and syntax-highlighted) — plus aSpanPayloadFormatTogglethat sits on the section trigger.The two share state through
