Greptile Summary

This PR bumps the Web SDK to version 26.0.0, introducing several breaking changes and new fields across models and services. All service methods are updated to pass X-Appwrite-Project and explicit accept headers per-call (rather than relying on the now-removed global header set by setProject()), setKey() and setForwardedUserAgent() are removed, and x-sdk-platform is corrected to 'client'.

• Breaking enum rename: Theme → BrowserTheme; presences list/get/upsert/update methods lose their generic type parameter and Models.DefaultPresence is removed.
• New model fields: User gains five optional email-metadata fields; Presence gains optional metadata; Membership gains userAccessedAt (typed as required — see inline comment).
• Client hardening: toString() on response objects now uses Object.defineProperty with enumerable: false to prevent the helper from leaking into JSON serialisation.

Confidence Score: 4/5

Safe to merge with one model type fix recommended before release.

The bulk of the change is a mechanical, generated update that correctly threads X-Appwrite-Project through every service call. The one substantive concern is Membership.userAccessedAt being typed as a required string when its JSDoc explicitly says "Show this attribute by toggling membership privacy in the Console" — meaning the field is absent from API responses by default.

src/models.ts — the Membership.userAccessedAt field type

Important Files Changed

Filename	Overview
src/models.ts	Adds email metadata fields (correctly optional) and Membership.userAccessedAt (incorrectly required — opt-in visibility means absent by default)
src/client.ts	Removes setKey/setForwardedUserAgent, moves X-Appwrite-Project from global headers to per-call, fixes toString() enumeration via Object.defineProperty, changes platform to 'client'
src/services/account.ts	All methods updated to include X-Appwrite-Project and accept headers per-call; OAuth endpoints correctly use text/html accept
src/services/functions.ts	Adds X-Appwrite-Project and accept: application/json headers to all three execution endpoints
src/services/presences.ts	Removes DefaultPresence generic; all four methods now return concrete Models.Presence types; adds metadata field support
src/enums/browser-theme.ts	Renamed from theme.ts to browser-theme.ts, enum renamed from Theme to BrowserTheme
CHANGELOG.md	26.0.0 entry incorrectly states setKey() and setForwardedUserAgent() were removed (they remain in client.ts)

Unused apiHeaders block in URL-building methods

All eight avatar methods return uri.toString() directly without calling this.client.call(). The apiHeaders object (including the newly added X-Appwrite-Project and accept values) is declared but never passed anywhere and has no effect. The same pattern is also present in the three URL-building methods in storage.ts (download, preview, view). The project identity is correctly carried via payload['project'] appended as a query parameter; the dead apiHeaders block just adds noise and could mislead maintainers.

Missing trailing newline at end of file — most editors and linters expect it.

createExecution always throws "File not found in payload"

chunkedUpload (line 910 in client.ts) immediately throws Error: 'File not found in payload' when no File instance is found in the payload. The createExecution payload only ever contains strings, booleans, and plain objects — never a File — so every call to createExecution will throw this error unconditionally, making the function completely non-functional in this release.
