Import official Android.Media.Quality first-fill documentation - #813

Tracks #153.

Documentation scope

Import 130 substantive first fills from 22 official Android developer-reference pages into 20 API XML files, using 13 individually reviewed offline batches capped at ten changes. Every production apply includes both docs\xml\Android.Media.Quality and docs\xml\ns-Android.Media.Quality.xml, plus the namespace. Existing nonplaceholder channels and XML outside Docs remain byte-identical; generated indexes and other namespaces are untouched.

The current whole-scope direct Docs leaf placeholder balance is 523 → 393: API 521 → 391, overview 2 → 2. The overview is scanned but its Name-only root is not selected by the existing namespace FullName filter; it remains unchanged. These structural counts are distinct from the issue's historical raw-text count.

Conservative source guards

Withhold 19 exact unsafe channels across 11 owners: eight parcel summary/remarks pairs containing Flatten this object in to a Parcel., two collection returns describing a single nullable profile, and one parameter-type value advertising combinations of mutually exclusive codes. Full official declarations, source identity, managed DocId/signature/ordered parameters/return and JNI identity bind each guard. Safe sibling channels remain usable through a direct first-fill-only path; authored or nested documentation is not repaired or enriched.

The complete final report records zero candidates/errors and 623 skipped entries: 223 missing member registrations, 46 missing type registrations, 19 ambiguous source channels, 37 nonmeaningful channels, 41 empty source documents, 1 missing parameter, 232 already-current remarks, 2 missing remarks, 20 missing returns and 2 missing summaries. Report entries are not a count of remaining placeholders.

Qualification

The ordinary full registered suite passed before changes and at the exact published head using default JIT dotnet run --no-cache -p:PublishAot=false tools\importer.cs -- --self-test. New tests retain complete original contiguous native declaration fragments and exercise real bounded production applies, zero-write repeats, identity/signature controls and authored/nested preservation. All inherited tests, fixtures, guide content and optional record fields are preserved.

A fresh initially empty own-cache online/offline pair differs only in three transport JSON fields and the TXT cache line. A real final offline apply records zero writes/errors with unchanged whole scope/tool bytes. Every authored channel is tied to an independently reviewed complete native source fragment; all 130 fragments compare byte-for-byte against the fresh sources. XML parsing and git diff --check pass. The independent complete binary inverse reconstructs the entire actual-main path/mode/blob tree (11,140 paths); the new fixture accounts for the proposed tree's 11,141 paths.

Original failures and limitations are retained: guard-test reader/setup failures precede the passing full suite; one concurrent offline evidence after-snapshot failed on disappearing self-test temporary files and has no retrospective native receipt; a separate serialized offline receipt is qualified. The first failed guard-suite snapshot omitted the then-untracked new fixture; later complete scopes include it. A pagination-reader assertion was corrected without changing or rerunning its original API payload. Fresh validation and fixtures are not a historical legacy-output baseline.
