2026-05-21 — Upgraded Chirpy to a fully-personalized Live Diagnostic Node & Mesh Assistant

• Integrated NodeRepository into GeminiNanoDocAssistant.kt and the Google AI Koin dependency injection module (GoogleAiModule.kt).
• Developed a dynamic live-state prompt formatting block within buildPrompt(...) that queries current hardware model, firmware version, connection status, GPS capability, channel utilization, airtime, battery level/voltage, user profile long/short names, and total registered mesh peer counts & active online peers directly from NodeRepository's reactive flows.
• Injected this live radio diagnostics context dynamically as a system instruction metadata block on every user query. This empowers the on-device model to answer real-time, personalized diagnostic questions (e.g. "what is my battery level?", "how many active nodes are on my mesh right now?") with 100% on-device offline accuracy.
• Tuned context retrieval constraints for the modern nano-v4-full (Gemini Nano v4) model: expanded the total context budget MAX_CONTEXT_CHARS from 8,000 to 32,000 characters (up to ~12K tokens out of the model's native 32K window), and scaled MAX_PAGE_CHARS to 16,000 characters and MAX_SNIPPET_CHARS to 8,000 characters to supply vastly richer, more detailed, and complete documentation fragments.

2026-05-21 — Activated full on-device token streaming and polished Chirpy's personality instructions

• Upgraded the on-device inference flow inside GeminiNanoDocAssistant.kt to use Firebase AI SDK's reactive generateContentStream(prompt) instead of the blocking generateContent invocation.
• Aggregated chunks and emitted incremental AIDocAssistantResult.Partial states down the Kotlin Flow, enabling true word-by-word/chunk-by-chunk streaming in the UI for a much more responsive user experience.
• Refined the SYSTEM_INSTRUCTION personality rules for Chirpy to position him as our adorable LoRa radio Node mascot instead of an avian theme, emphasizing high-enthusiasm mesh networking, signal connectivity, battery status, and radio/routing concepts (e.g. "fully charged", "relaying info", "staying connected") while preserving technical precision.
• Significantly increased the frequency and flavor of mesh networking, hardware, and radio puns (e.g. "let's relay some knowledge!", "channeling my inner router!", "completely on the same frequency!") to make Chirpy incredibly fun and interactive.
• Overhauled system error messages inside DocsNavigation.kt and the loading bubble state inside ChirpyAssistantSheet.kt to align with the highly-enthusiastic mascot theme (e.g. "routing through the mesh… 📡", "channel is totally congested… 📶", "battery is charging or firmware is still downloading… 🔋").

2026-05-21 — Implemented streaming chat support and Firebase Remote Config integration for Chirpy

• Added firebase-config dependency to Version Catalog libs.versions.toml and androidApp/build.gradle.kts.
• Added the AIDocAssistantResult.Partial variant to support intermediate stream updates.
• Extended the AIDocAssistant interface and implemented answerStream in both KeywordFallbackAssistant and GeminiNanoDocAssistant.
• Integrated Firebase Remote Config into GeminiNanoDocAssistant to dynamically fetch the model name (chirpy_model_name) and system instruction (chirpy_system_instruction) with release-optimized fetch intervals.
• Refactored GeminiNanoDocAssistant.answer to reuse answerStream flow under the hood, eliminating duplicate prompting code.
• Integrated the streaming flow into the Compose UI layer (DocsNavigation.kt), appending a placeholder message and updating it in place on each stream emission.
• Verified that all unit tests (:feature:docs:allTests) and static analysis checks (spotlessApply spotlessCheck detekt) pass 100% green.

2026-05-21 — Fixed Chirpy Assistant invalid model name and enhanced failure fallback suggestions

• Fixed a 404/Unknown inference error by updating GeminiNanoDocAssistant.kt's MODEL_NAME from "gemini-3.1-flash-lite" to the correct Firebase AI Logic preview name "gemini-3.1-flash-lite-preview".
• Overhauled multi-turn hybrid chat seeding: eliminated the redundant and wasteful background chat.sendMessage network/token call on the first turn. Instead, if the first turn is answered on-device, the session caches the question and answer locally, and starts the subsequent cloud-chat session with these pre-loaded into the startChat(history = ...) parameter.
• Expanded the hybrid model's looksLikeNoAnswer heuristics to better detect when the on-device model fails or has limited info, allowing seamless fallback to the grounded cloud model.
• Polished DocsNavigation.kt's chirpyResultToMessage system error handling to map raw exception/object types (e.g., DocsAiError.Unknown) to polished, friendly user-facing messages.
• Programmed a smart fallback in the UI: if an inference error occurs (e.g. offline, rate limit, or model not found), Chirpy now automatically displays local keyword search results as recommended page chips so the user is never left stranded.
• Verified 100% compliance with Spotless, Detekt, and unit tests (:feature:docs:allTests and :androidApp:testGoogleDebugUnitTest are fully green).

2026-05-20 — Decoupled and Isolated Flatpak manifest generation logic to build-logic/flatpak

• Isolated the optimized GenerateFlatpakSourcesTask from monolithic build-logic/convention into its own specialized, lightweight :flatpak subproject under build-logic.
• Created :flatpak configuration and registered the formal plugin ID "meshtastic.flatpak" implemented by FlatpakConventionPlugin inside the default package namespace (perfectly matching project-wide plugin architectures).
• Implemented modern, configuration-cache-safe lazy provider directory evaluation for the default Gradle user home cache.
• Cleaned up :convention by removing the redundant class and registration imports from RootConventionPlugin.kt.
• Applied the new plugin in the root build.gradle.kts using id("meshtastic.flatpak").
• Verified 100% compliant spotless and detekt formatting checks (./gradlew spotlessCheck detekt is green).
• Successfully committed and pushed the branch fix/flatpak-snapshot-resolution to remote jamesarich with proper GITHUB_TOKEN environment bypass.
• Consolidated and updated GitHub PR #5542's description to comprehensively document the correctness, performance, and modular isolation of the Flatpak generator.

2026-05-20 — Extracted GenerateFlatpakSourcesTask to precompiled build-logic convention plugin

• Audited the Flatpak build structure and successfully extracted the entire task logic, data classes, and extension helpers from loose script files to a precompiled compiled Kotlin class: build-logic/convention/src/main/kotlin/org/meshtastic/buildlogic/GenerateFlatpakSourcesTask.kt.
• Registered the task directly within RootConventionPlugin.kt and removed the legacy gradle/flatpak.gradle.kts script block from the root build.gradle.kts file entirely.
• Resolved and fixed an implicit Gradle non-serializable property capture inside the lazy property mappings, ensuring full compliance with the Gradle Configuration Cache and restoring successful cache storage with zero errors.
• Validated with complete clean building (./gradlew clean) and static code analysis (./gradlew spotlessCheck detekt), completing with 100% green passes.

2026-05-20 — Optimized GenerateFlatpakSourcesTask for performance and correctness

• Optimized GenerateFlatpakSourcesTask in gradle/flatpak.gradle.kts by implementing single-pass Maven metadata XML pre-indexing (O(1) lookups) and deferred SHA-256 calculation (executing digests only on deduplicated, finalized resources).
• Refactored loose map structures into strongly-typed Gradle-compliant internal data classes (SnapshotVersion, SnapshotMetadata, and FlatpakSourceCandidate) to improve type safety and maintainability.
• Verified output correctness: the optimized manifest output flatpak-sources.json is 100% character-for-character identical to the original unoptimized output.
• Successfully passed all static analysis and code quality checks with ./gradlew spotlessCheck detekt (100% green).

2026-05-20 — Implemented dynamic Gradle cache SNAPSHOT metadata resolution for Flatpak offline builds

• Overhauled GenerateFlatpakSourcesTask in gradle/flatpak.gradle.kts to identify -SNAPSHOT dependencies, parse local cached maven-metadata.xml in resources-2.1, and dynamically map them to remote timestamped snapshot URLs (e.g. Sonatype Snapshots) while preserving their original non-timestamped file names as dest-filename.
• Created a pure JDK XML parser within the task to parse the <snapshotVersions> block from cached XML files.
• Verified that compiling the desktopApp and running the flatpak generator task successfully maps snapshot dependencies (such as org.meshtastic:takpacket-sdk-jvm:0.2.4-SNAPSHOT) to their remote unique snapshot URLs in flatpak-sources.json.
• Ran quality and validation checks: ./gradlew spotlessCheck detekt (100% SUCCESSFUL with zero issues).

2026-05-20 — Resolved Flatpak jitpack.io dependency download 404s in sandboxed offline builds

• Modified GenerateFlatpakSourcesTask in gradle/flatpak.gradle.kts to dynamically detect dependency groups starting with com.github. (which are hosted on JitPack).
• Configured the generation of primaryUrl for these dependencies to resolve directly from https://jitpack.io and created custom high-availability fallback lists.
• Verified that compiling the desktopApp and running the flatpak generator task (./gradlew :desktopApp:assemble :generateFlatpakSourcesFromCache --no-configuration-cache) successfully produces a valid 10MB flatpak-sources.json containing correctly mapped JitPack URLs.
• Ran quality and validation checks: ./gradlew spotlessCheck detekt (100% SUCCESSFUL with zero issues).

2026-05-20 — Replaced standalone translations landing page with dynamic global header language switcher dropdown

• Deleted redundant standalone page docs/en/translations.md and updated docs/README.md to reflect layout change.
• Completely re-engineered docs/_includes/language_switcher.html to:
  1. Dynamically parse active page paths and locales, matching default English pages with translated variants.
  2. Bind button text to native active language names (e.g., displaying "Беларуская" instead of hardcoded "English").
  3. Pre-verify file existence in site.pages to only render valid translation links, preventing any 404 errors.
  4. Automatically hide the language switcher on English pages that do not have translations available yet.
• Modified custom CSS styles in docs/_includes/head_custom.html to use right: 0; left: auto; layout alignment, preventing dropdown menu overflows on smaller screens.
• Successfully built and verified live documentation pages in the browser using the browser subagent, confirming fully operational dynamic swappers.
• Ran quality and validation checks: ./gradlew generateDocsBundle validateDocsBundle spotlessCheck detekt (100% SUCCESSFUL).

• Run and verified Gradle documentation bundle compilation: ./gradlew generateDocsBundle validateDocsBundle (PASSED: 672 pages).
• Validated formatting and static analysis rules: ./gradlew spotlessApply spotlessCheck detekt (100% green).
• Successfully completed full baseline compilation checks with ./gradlew assembleDebug.

2026-05-20 — Completely overhauled, simplified, and pushed Flatpak offline source automation

• Completely retired the third-party flatpak-gradle-generator plugin and its associated complex configuration and library overrides (removed ~150 lines of boilerplate).
• Implemented a native JVM-based custom Gradle task GenerateFlatpakSourcesTask inside gradle/flatpak.gradle.kts which walks the post-compilation Gradle cache and generates a perfectly sorted, deduplicated flatpak-sources.json in under 3 seconds.
• Integrated high-availability mirror URL generation (Google, Gradle Plugin Portal, GCP Maven Central, and Aliyun Maven repositories) for complete build robustness during Flathub sandboxed offline builds.
• Streamlined CI workflow files .github/workflows/release.yml and .github/workflows/reusable-check.yml to call our native Gradle task.
• Validated all formatting and static analysis checks using ./gradlew spotlessCheck detekt (100% green).
• Committed, successfully pushed the branch fix/flatpak-sources-automation to remote jamesarich, and updated the PR description on GitHub for PR #5533.

2026-05-20 — Rebased Flatpak Optimization Branch onto upstream/main

• Successfully rebased the working branch fix/flatpak-sources-automation onto the latest fetched origin/main (upstream).
• Resolved potential rebase history divergence by preserving only our unique conflict-bypassing override commit and skipping squash-merged commits.
• Updated git submodules to track the new upstream base commit.
• Re-ran all baseline quality and static analysis checks (spotlessCheck, detekt) and confirmed 100% success.
• Validated end-to-end correctness by running :combineFlatpakSources to verify complete and correct generation of the consolidated flatpak-sources.json manifest with 2,339 unique resources.

2026-05-20 — Overhauled and Bulletproofed Flatpak Source Generation

• Overhauled and streamlined build-logic/convention/build.gradle.kts to dynamically query and resolve all 25+ Version Catalog plugin marker coordinates in a type-safe dynamic loop.
• Replaced the hardcoded embedded Gradle Kotlin compiler version with dynamic standard library detection: KotlinVersion.CURRENT.toString().
• Implemented root Gradle consolidator task :combineFlatpakSources using JVM-native Json Slurper/Output, deduplicating 2222 entries and injecting Google/Aliyun backup mirror-urls.
• Streamlined reusable-check and release CI workflows, replacing complex jq hacks with a simple, single gradle task invocation.
• Verified spotlessCheck, detekt, and end-to-end completely offline package builds (--offline) completed with 100% success.

2026-05-20 — Refactored and polished Flatpak dependency manifests to modern Gradle standards

• Polished the Flatpak generator tasks and convention setup following a comprehensive audit:
  1. Centralized version definitions to reference the central libs.versions catalog (kotlin, koin.plugin, etc.) instead of hardcoded strings.
  2. Documented every single dependency override and compiler-plugin helper with clear, inline comments (// why: ...).
  3. Cleaned out legacy dependencies and streamlined core:database to only capture kspKotlinJvmProcessorClasspath.
  4. Changed includeConfigurations to use type-safe setOf instead of listOf to align with Gradle's SetProperty APIs.
• Verified that all static analysis checks pass successfully: ./gradlew spotlessCheck detekt is 100% green.
• Validated end-to-end correctness by successfully compiling the app completely offline (--offline) and packaging the release UberJar.

2026-05-20 — Fixed Jekyll documentation site build and deployment in CI

• Created docs/index.html to automatically redirect root path requests (/) to the English directory (/en/).
• Updated .github/workflows/docs-deploy.yml to compile the Jekyll root site using --baseurl /${{ github.event.repository.name }} and setup Ruby with version 4.0.4 to match project release workflow conventions.
• Updated .github/workflows/docs-release.yml to compile both versioned and root Jekyll sites, assemble them into build/final_site/ with Dokka HTML references, configure correct baseurls respectively, and setup Ruby with version 4.0.4.
• Verified that local Gradle docs tasks (generateDocsBundle, validateDocsBundle, publishDocsSite) compile successfully and the redirect file is correctly populated in the output.

2026-05-20 — Optimized slow Flatpak CI jobs

• Restrained flatpakGradleGenerator to target only the runtimeClasspath configuration in desktopApp and build-logic:convention modules.
• Updated release.yml and reusable-check.yml to invoke only targeted tasks (:desktopApp:flatpakGradleGenerator and :build-logic:convention:flatpakGradleGenerator) instead of running the task on the root and all subprojects.
• Retained Matrix architecture runner configuration for build validity, as Skiko/Compose Desktop native artifacts are resolved dynamically based on host architecture.
• Cleaned up leftover speed-up workarounds: completely removed the Flatpak Gradle Generator plugin application and tasks from the root project and all other library/feature subprojects (core:ble, core:common, core:database, core:model, core:navigation, core:proto, and feature:messaging), including deleting the unused flatpakKmpAndroidMeta configuration from feature:messaging.
• Verified that local execution of :desktopApp:flatpakGradleGenerator runtimeClasspath resolution speed dropped from 46 seconds to 12 seconds, and all Spotless and Detekt linting checks passed.

2026-05-12 — Implemented Apple alignment for docs feature (FR-038)
