Investigate API typos found by introspection TypoTest

[rolfbjarne]

The introspection TypoTest spell-checks our API names and maintains an allowed-word list. A recent cleanup of this test (PR #25393) identified a number of words that appear to be genuine typos in Apple's APIs (or our bindings of them).

Two analysis files have been created with the full list of typos and their source references:

• New typos (12 words found during the cleanup): newwords.md
• Existing typos (62 words already in the allowed list): existingwords.md

Each typo entry includes a permalink to the source code and the actual code line.

Task

Go through the list of typos in both files and decide for each one:

1. Real typo — fix it: Add a properly spelled API alongside the misspelled one, and obsolete the old one. This applies to typos in our bindings (e.g. missing camelCase splits like Adjustmentfor → AdjustmentFor, or misspellings like Achivements → Achievements).

2. Not a typo / Apple's spelling: If the misspelling originates from Apple's API and we must match it exactly, document why the word is in the allowed list (e.g. Referer is the historic HTTP spelling from RFC 2616). These should not be "fixed" but could benefit from better documentation.

Examples from the lists

Word	Issue	Category
Achivements	achievements (missing e)	Our binding — fixable
Adjustmentfor	AdjustmentFor (missing camelCase)	Our binding — fixable
Referer	referrer (RFC 2616 spelling)	Apple/HTTP convention — document
Tesselation	tessellation (single l)	Apple's spelling — document
Cancellable	cancelable (British variant)	Acceptable variant — not a typo

CI Post-Mortem Update (June 8–15, 2026)

The Introspection.ApiTypoTest.TypoTest failure continues to affect all PR builds on macOS. This is a shared regression — not PR-specific.

Occurrence Summary

PR	Build	Bot	Direct Link
#25657	14376282	VSCXSDKs-MINI-033.Tahoe.arm64	introspection → Run tests
#25656	14376284	VSCXSDKs-MINI-059.Tahoe.arm64	introspection → Run tests
#25607	14376288	MACIOSMINI-028.Tahoe.arm64	introspection → Run tests
#25379	14376293	MACIOSMINI-008.Tahoe.arm64	introspection → Run tests

Total: Failed in 4 builds across 4 unrelated PRs this week (100% failure rate for macOS introspection).

Error Details

All builds report the same set of typos on introspection/macOS/Debug:

Common typos (all 4 builds):

[FAIL] Unnecessary allowed typo "Arae" is not present in any API name
[FAIL] Unnecessary allowed typo "Mada" is not present in any API name
[FAIL] Unnecessary allowed typo "Nanaco" is not present in any API name
[FAIL] Unnecessary allowed typo "Otsu" is not present in any API name
[FAIL] Unnecessary allowed typo "Suica" is not present in any API name
[FAIL] Unnecessary allowed typo "Waon" is not present in any API name

These appear to be PKPaymentNetwork values that were removed from the macOS 26 SDK.

Additional typos (3/4 builds):

[FAIL] Typo in METHOD name: get_TimelapseVideosFilter - Timelapse, Type: PHPickerFilter
[FAIL] Typo in METHOD name: get_PrevColorTexture - Prev, Type: IMTLFXFrameInterpolatorBase
[FAIL] Typo in METHOD name: set_PrevColorTexture - Prev, Type: IMTLFXFrameInterpolatorBase

Classification

This failure is a shared regression — it affects every macOS introspection run regardless of PR content. The unnecessary allowed typos suggest these words (Arae, Mada, Nanaco, Otsu, Suica, Waon) were removed from the API and their entries in the allowed typo list should be cleaned up. The method name typos ("Timelapse", "Prev") need to either be added to the allowed list or the binding names corrected.
