Changelog

0.2.3 — Complete SAF-D1 diagnostic source / pinned toolchain (2026-09-24)

Integrate the previously separate SAF-D1 diagnostics into the full 0.2.2 source; retain the PDF lifecycle correction, folder cursor-result correction, and tests.
Pin Gradle 8.14.5 across the wrapper and both bootstrap scripts with official hashes.
Require a local JDK 17 via checked-in daemon criteria, compilation toolchains, bytecode targets and settings guards; keep Kotlin 2.2.21 / AGP 8.11.1 unchanged.
Add offline build-pin/plugin-ID checks; preserve the five unique root plugin aliases.
Set versionName 0.2.3 / versionCode 5 and a visible release/SAF-D1 footer.
Clarify fresh-extraction setup and that the persistent folder failure remains unresolved.
No extra permissions, document-engine changes, JDK/SDK binaries or compiled APK.

0.2.2 — Folder-listing runtime fix (2026-09-24)

Check the provider cursor for null before entering use, rather than treating the optional EXTRA_ERROR field's absence as a missing listing.
Preserve normal/empty/partial listings, cursor cleanup, row limits and provider messages.
Add five Android provider regression cases and an offline host harness that tests the actual production cursor-reading block with test doubles.
Reproduce the original exception (9/14 host failures); fixed block passes 14/14. Existing portable checks remain 112/112. Android build/device validation of this patch is not claimed; the one-file patch preserves local build-tool changes.

0.2.1 — Android PDF smoke-test compilation fix (2026-09-24)

Fixed PdfDocument().use in ViewerSmokeTest.kt: Android's PdfDocument exposes close() but implements neither Closeable nor AutoCloseable; use explicit try/finally instead.
Finish the started PDF page in finally, close the document and render client explicitly, use a unique temporary fixture, and delete that fixture even when its creation fails.
Add a narrowly scoped source check for the exact invalid constructor/use pattern.
No runtime feature changes or dependency upgrades; Android/device verification remains pending.

0.2.0 — Lightweight Android browser and file picker (2026-09-23)

Added native saved-folder browsing, breadcrumbs/Up/refresh, current-folder search, name/date/size/type sorting, dotfile visibility, metadata, optional provider thumbnails, and Browse/Recent tabs.
Reused the current preview pipeline; preserved browser navigation/scroll through preview and Back.
Added explicit external-open chooser using read-only copies, including unsupported preview formats.
Registered APP_FILES, content-directory VIEW, and a dedicated GET_CONTENT selection activity.
Added MIME-filtered, optional multi-selection, review/confirm/cancel, LOCAL_ONLY system delegation, narrow copied-URI results, and preserved MIME metadata for extensionless output copies.
Separated saved tree-grant ownership from recent-file cleanup; protected concurrent viewer snapshots.
Sanitized exported activity extras before SavedStateHandle defaults can be populated.
Added shared portable browser policies and stream-copy budgets; 112 offline core/JVM checks pass.
Added Android provider/picker instrumentation source and debug-only synthetic documents, not executed.
Expanded documentation, static invariants and a repeatable Kotlin PSI syntax check.
Android/Apple build and device verification are still pending; no APK or native Office engine bundled.

0.1.0 — MVP source release

Android read-only viewer implementation with system file integration, recent files, PDF/image views, local reading previews, source/CSV/ZIP views, search, sharing, copies and labelled text export. Shared Kotlin Multiplatform core; bounded JVM ZIP adapter; isolated PDF service; policy/test suite; Apple framework targets and port plan; source-only Gradle wrapper bootstrap with pinned checksums.

Executed validation: 75 core/JVM checks, source syntax and structural checks. Android/iOS builds, visual checks and runtime testing not performed; no APK included. No native Office engine, editing, full Office fidelity or iOS application claimed.
