Use this skill whenever a user asks for README screenshots, app-store-like repository images, a populated mesh-chat showcase, voice-note or media conversation captures, a geohash globe image, higher-resolution Android emulator captures, or a PR that adds or replaces documentation screenshots. It owns the complete workflow from latest-main isolation and deterministic synthetic fixtures through real app rendering, visual inspection, system-chrome cropping, README asset updates, clean builds, and an optional PR. Do not use it for before/after UI regression evidence, which belongs to android-ui-visual-review, or for physical mesh behavior, which belongs to mesh-lab. +compatibility: Requires git, gh, the Android SDK and emulator, adb, Java/Gradle, Python 3, and image inspection support. FFmpeg is useful for capture-only media preparation. +--- + +# Android README Screenshot Studio + +Create repository screenshots from the real Bitchat Android UI, not from a +drawn mockup. The result should look intentional enough for the top of the +README while remaining reproducible, synthetic, and honest about what a static +emulator capture proves. + +## Resolve the brief + +Extract as much as possible from the conversation before asking questions. +Confirm or infer: + +1. Which surfaces are needed, such as mesh chat and geohash globe. +2. The exact visible state and ordering. Treat phrases like “photo, messages, + three voices, thumbs-up” as a chronological contract rather than a loose + suggestion. +3. Whether existing README images should be preserved, replaced, or added. +4. The target base. Default repository work to the latest `origin/main`. +5. Whether GitHub publication and merge are authorized. A request to “open a + PR and merge it” authorizes both; otherwise do not merge. + +Do not invent the subject of a requested photo. Nicknames, channel names, or +previous fixture copy are not sufficient justification for choosing an outdoor, +urban, political, or personal scene. Reuse an existing rights-safe asset when +the subject should remain stable, or ask for the intended subject. If the user +explicitly approves synthetic imagery, disclose it and keep its source +capture-only unless they request a committed asset. + +Read [references/showcase-recipes.md](references/showcase-recipes.md) for every +run. It contains the concrete mesh-chat and globe recipes, framing guidance, +the verified current-pair fast path, and the final acceptance checklist. When +the request matches the existing README pair and the production UI has not +materially changed, try that fast path first and then validate every visible +result. Fall back to tracing the current implementation when an entry point, +state model, or composition has changed. + +When a populated screen requires a debug fixture, also read +[../android-ui-visual-review/references/fixture-recipes.md](../android-ui-visual-review/references/fixture-recipes.md). + +## Work in a fresh tree + +Protect the user's active checkout: + +1. Inspect `git status` without modifying it. +2. Fetch `origin/main`. +3. Create a new `codex/` branch in a temporary worktree rooted at the current + `origin/main`. +4. Keep screenshots and raw captures in a separate temporary artifact + directory so cleanup or checkout operations cannot remove them. + +Do not switch the user's original checkout, reuse a dirty branch, or mix an +unrelated PR into the screenshot change. If the request continues an existing +screenshot PR, reuse its already-isolated worktree only after verifying its +head and base. + +## Establish the capture contract + +Before building, write a compact local matrix containing: + +- surface and navigation path; +- chronological fixture contents; +- expected visible top and bottom rows; +- emulator profile class, portrait orientation, theme, and locale; +- crop policy and final asset dimensions; +- existing asset path and README reference; +- behaviors the static screenshot does not prove. + +Use the current production UI and latest `main` interaction model. Trace the +screen entry point and state source before adding a fixture. A beautiful capture +of a stale or fake UI is not acceptable. + +## Use a high-resolution Android canvas + +Prefer the newest stable Android runtime installed locally and a large, +high-density portrait emulator profile. Reuse a previously validated capture +profile when it remains available, but verify the guest properties and keep +the resulting profile facts in the local capture contract rather than the +repository or GitHub text. + +After boot, record the guest values with an explicit emulator selector: + +```sh +adb -s "$ANDROID_README_SERIAL" shell getprop ro.build.version.release +adb -s "$ANDROID_README_SERIAL" shell getprop ro.build.version.sdk +adb -s "$ANDROID_README_SERIAL" shell getprop ro.build.version.security_patch +adb -s "$ANDROID_README_SERIAL" shell wm size +adb -s "$ANDROID_README_SERIAL" shell wm density +``` + +Never publish emulator selectors, AVD names, local paths, usernames, IP +addresses, or other machine identifiers. + +## Build a deterministic showcase fixture + +Launch the Activity before injecting process-local state. Prefer existing debug +hooks. If they cannot express the composition, add the smallest temporary +command under: + +```text +app/src/debug/java/com/bitchat/android/testhook/ +``` + +The fixture should: + +- use synthetic names, peer IDs, message IDs, and copy; +- use the real local mesh peer ID for self-authored messages; +- use a fixed epoch so timestamps and ordering are stable; +- insert records in the exact requested chronology; +- report structured counts through the test-hook result file; +- copy capture-only media into the app's cache or files directory; +- populate only the peers and state needed for the header; +- avoid persistence unless persistence itself is the subject. + +For voice notes, route real audio files through the app's waveform extractor. +Use short, distinct, locally synthesized speech clips or other rights-safe +speech audio. Never draw a decorative waveform and call it speech. Wait for +asynchronous decoding before capture, then inspect that pauses and syllable +envelopes look plausibly different between notes. + +For image attachments, use a rights-safe existing asset or an explicitly +approved synthetic source. Keep fixture media outside production source sets +and remove every capture-only hook before committing. Compose image rows may +remember a decoded bitmap by file path. After replacing the bytes at an +unchanged path, relaunch the app or use a new destination path before judging +the revised crop. + +## Capture from the real app + +Build and install the ABI-matching debug APK, satisfy onboarding and +permissions, inject the fixture, and navigate to the intended surface. + +Capture directly: + +```sh +adb -s "$ANDROID_README_SERIAL" exec-out screencap -p > "$ARTIFACT_PATH" +``` + +Inspect the full screenshot immediately. Check message count and order, +nickname ownership, peer count, waveform variety, image visibility, globe +center, grid precision, clipping, and composer placement. + +Inject a complete timeline in one operation and allow at least two seconds of +quiet UI time after the fixture reports success. This avoids capturing entry +animations, incomplete placement, or media that has not finished decoding. + +Crop only Android system chrome. Preserve Bitchat's app header, translucent +overlap, content, and composer. Derive the crop from the observed status and +navigation insets; do not blindly reuse pixel offsets from a different profile. +Because the app renders edge-to-edge, app controls may extend into the reported +navigation inset. Place the bottom crop after the final control outline and +shadow but before the system gesture affordance; removing the entire inset can +clip the app itself. +Keep every final README screenshot in a matched portrait size. + +Use image inspection after the crop. File dimensions and a successful ADB +command do not prove that the desired composition is visible. + +## Update repository assets + +Discover the current README references before writing. Prefer stable paths under +`docs/screenshots/` and replace only the assets the user requested. + +When adding a showcase section: + +- keep the layout readable on GitHub; +- give every image meaningful alt text; +- use relative repository paths; +- avoid machine-generated cache files or capture sources; +- keep paired screenshots at identical dimensions. + +Run the bundled validator for every final asset: + +```sh +python3 \ + .agents/skills/android-readme-screenshot-studio/scripts/validate_readme_screenshots.py \ + --repo-root . \ + --readme README.md \ + --require-same-size \ + --asset docs/screenshots/readme-mesh-chat.png \ + --asset docs/screenshots/readme-geohash-globe.png +``` + +When replacing only one image in an existing pair, pass both the changed and +unchanged assets with `--require-same-size`, and verify the unchanged asset's +checksum. Pass only one asset and omit `--require-same-size` only when the +README has no paired screenshot to preserve. + +## Remove the fixture and verify cleanly + +Before committing: + +1. Remove temporary imports, commands, helpers, resources, and fixture media + with a focused patch. +2. Verify `git diff -- app/src/debug` is empty. +3. Verify `git status --short` lists only the intended README and screenshot + files. +4. Run `git diff --check`. +5. Run `./gradlew assembleDebug` after fixture removal. +6. Re-run the screenshot validator. +7. Confirm the user's original checkout is still untouched. + +The final commit must not contain synthetic peer data, generated photo sources, +audio clips, ADB outputs, emulator configuration, or local capture reports +unless the user separately requested those artifacts in the repository. + +## Record honest evidence + +Use the capture manifest and report format from +`../android-ui-visual-review/` when before/after evidence is useful. For a +README-only change with no production UI delta, identical before/after images +are acceptable when explicitly labeled “no production UI delta.” + +State limitations plainly: + +- a populated mesh timeline proves rendering, not physical message delivery; +- a voice row proves waveform rendering, not audio playback; +- an attachment proves image rendering, not media transfer; +- a globe proves picker state, not live location or relay behavior. + +## Commit, publish, and optionally merge + +GitHub writes require user authorization. When authorized: + +1. Stage only intended files. +2. Commit without overriding author or committer identity. +3. Push the `codex/` branch. +4. Use `gh pr create` or update the existing PR. +5. Describe the exact capture sequence, synthetic fixture disclosure, + repository-safe validation commands, and limitations. Keep emulator, + runtime, hardware, and local-environment facts out of GitHub text whenever + repository privacy rules classify them as machine identifiers. +6. Verify the PR head and checks with `gh pr view` and `gh pr checks`. +7. Merge only when the user explicitly requested it and required checks allow + it. Prefer the repository's normal merge strategy and use `gh`. +8.

Use synthetic names and avoid real +locations, contacts, identities, or sensitive content. + +For public mesh rendering, pass the current mesh peer ID as `senderPeerID` on +self-authored messages. This exercises the same ownership and color path as +production. Alternate sender IDs so every back-and-forth row renders its sender +header instead of being grouped away. + +### Photo framing + +A portrait or tall crop can let the latest rows stay visible while the older +photo slides partially behind Bitchat's translucent header. This is visually +useful only when the photo subject remains legible. + +- Preserve the app's own rounded image treatment. +- Do not bake UI chrome into the photo. +- Avoid important content under the header overlap. +- Do not select a photo subject from nicknames alone. +- If generating a synthetic photo, obtain or infer subject approval first, + disclose generation, and keep the source outside the final commit unless + requested. + +### Natural voice rows + +Prepare three short speech clips with different durations, pauses, and cadence. +Locally available offline TTS plus an audio transcoder is sufficient. Use the +same audio format the app normally records or plays, such as M4A. + +After copying the files into an app-readable location, create +`BitchatMessageType.Audio` messages that point to those actual files. Let +`AudioWaveformExtractor` and `VoiceWaveformCache` produce the bars. + +Reject the capture when: + +- all three envelopes look identical; +- the bars are uniform or sinusoidal rather than speech-like; +- duration labels are missing or implausible; +- a waveform is clipped by the screen edge; +- a temporary progress or cancel state is visible. + +### Layout tuning + +Inject the complete fixture in one operation so the list adopts it as history +instead of animating rows during capture. Let the reverse-layout list settle at +the newest message. + +If the oldest photo is not partially visible, prefer changing its aspect ratio +or the number of short text rows over manually scrolling to an unstable offset. +If the newest reaction falls behind the composer, shorten earlier content or +reduce media height. Do not crop app content to solve a fixture problem. + +## Geohash globe showcase + +### Visual goal + +Show: + +- the entire Earth; +- a readable geohash grid; +- the selected coarse cell; +- the requested geographic focus beneath the selection crosshair; +- the picker hint and precision controls. + +Use the current picker Activity and renderer. Do not composite a globe or grid +outside the app. + +### Focus without zoom + +When a user says “focus on the Middle East, no zoom”: + +1. open or seed the picker at a geohash centered on the requested area; +2. allow the globe to center on that location; +3. reduce precision to the same coarsest whole-Earth level used for the + showcase; +4. preserve camera distance while confirming the center moved; +5. capture with the whole globe still visible. + +The exact seed may change with picker implementation. Validate against visible +geography and the selected geohash label rather than assuming the seed worked. + +Reject the capture when: + +- the requested region is off-center; +- Earth is clipped; +- reducing precision also changed the camera distance against the brief; +- the selected cell or crosshair is illegible; +- controls overlap the globe; +- stale system bars remain in the final README asset. + +## Crop and output + +Capture the full physical screen first. Determine the status-bar and +navigation-bar insets from the current profile, then crop those insets only. + +Treat the navigation inset as an inspection region, not an automatic crop +amount. Bitchat uses edge-to-edge layout, so the composer's border, globe-button +corners, or their shadows may occupy part of that region. Use accessibility +bounds plus full-size pixel inspection to place the crop below every app +control and above the system gesture affordance. + +Treat previously observed crop offsets as local evidence, not as a universal +rule or repository documentation. Re-measure when the profile changes. + +Every paired README image should: + +- be a valid PNG; +- share width and height; +- retain the app header and composer or controls; +- exclude Android status

Use this skill whenever a user asks for PR screenshots, branch UI comparisons, visual regression evidence, Compose before/after captures, populated message-state screenshots, responsive/theme/locale comparisons, or GitHub comments containing Android UI evidence—even if they only say “show me what changed.” Also use it to determine and document that a suspected UI PR has no visual delta. Do not use it for implementing a new UI, ordinary code review without visual evidence, or physical mesh validation. +compatibility: Requires git, the Android SDK and emulator, adb, Java/Gradle, Python 3, and gh for pull-request resolution or publishing. +--- + +# Android UI Visual Review + +Turn a PR or branch into trustworthy visual evidence. The comparison is useful +only when the before and after builds use the correct commits, Android runtime, +viewport, app state, and navigation path. + +## Collect the two user choices + +Before starting, resolve: + +1. **Target** — a PR URL/number or a branch/commit. If it is missing, ask for it. + For a branch, also ask for the intended base when it cannot be inferred + safely; otherwise default to the repository's `main`. +2. **Publishing** — for a PR target, ask whether the final screenshots and + findings should stay local or be posted as a PR comment. Do not perform any + GitHub write unless the user explicitly chooses publishing. A prior explicit + request such as “post these to the PR” already answers this question. + +Do not block on publishing preference while doing read-only analysis if the user +has not answered yet. Keep the local workflow useful on its own. + +## Read the routed guidance + +- Read [references/analysis-playbook.md](references/analysis-playbook.md) for + every run. It explains how to map a diff to screens, states, and a capture + matrix. +- Read [references/fixture-recipes.md](references/fixture-recipes.md) whenever + the affected screen needs messages, peers, channels, nicknames, settings, + permissions, locale, theme, onboarding state, or another non-empty fixture. +- Read [references/github-publishing.md](references/github-publishing.md) only + when the user has opted into a PR comment. + +## Create an isolated review session + +Never switch the user's active checkout between before and after revisions. +Run from the repository root: + +```sh +.agents/skills/android-ui-visual-review/scripts/create_review_worktree.sh \ + --target "" +``` + +For a branch with a non-default base: + +```sh +.agents/skills/android-ui-visual-review/scripts/create_review_worktree.sh \ + --target "" \ + --base "" +``` + +The script fetches a PR head when needed, computes the **actual merge-base**, +creates a detached temporary worktree at the before SHA, and prints: + +- session directory +- worktree path +- artifact directory +- before and after SHAs +- PR number/base metadata when applicable + +Keep artifacts outside the worktree so checkouts cannot remove them. The script +may symlink the ignored `local.properties` into the temporary worktree; never +publish it or quote its contents. + +If a review session already exists and its SHAs are verified, reuse it. Do not +create a second worktree for the same run. + +## Establish the visual contract + +Use the actual diff, not the PR title, to determine what should be visible. + +1. Record `git diff --stat`, `--name-status`, and the focused diff between the + before and after SHAs. +2. Trace changed UI symbols to their composable/activity, state source, entry + point, and prerequisites. +3. Separate direct visual changes from indirect ones such as dynamic color, + locale recreation, launcher resources, default data, or backend state shown + by an otherwise unchanged screen. +4. Produce a local capture matrix before building. Each row should define: + screen, navigation path, fixture, logical width, theme, locale, permissions, + and what difference is expected. +5. Include a control state where the UI should remain unchanged when that helps + distinguish intentional degradation from a regression. + +When the diff contains no UI/resource/state-to-UI change, say so. If the user +asked for a screenshot for every target, capture the nearest affected surface +before and after and label the expected result **no visual delta**. Do not invent +a UI claim for a behavioral fix. + +## Use the newest stable Android runtime + +Prefer an emulator for repeatable UI evidence. At run time: + +1. Inspect installed SDK/system images and current official Android release + information. Choose the newest **stable** API; do not silently use a preview. +2. Create a dedicated AVD and isolated data directory when possible. If current + command-line tools cannot create a newly versioned image (for example an + extension image), a verified `-sysdir` override with an isolated data + directory is acceptable. +3. After boot, record guest properties rather than trusting the AVD name: + +```sh +adb -s "$ANDROID_REVIEW_SERIAL" shell getprop ro.build.version.release +adb -s "$ANDROID_REVIEW_SERIAL" shell getprop ro.build.version.sdk +adb -s "$ANDROID_REVIEW_SERIAL" shell getprop ro.build.version.security_patch +adb -s "$ANDROID_REVIEW_SERIAL" shell wm size +adb -s "$ANDROID_REVIEW_SERIAL" shell wm density +``` + +Use an explicit emulator serial for every ADB command when any physical device +is also connected. Never put serials, device names, local paths, IP addresses, +or other machine identifiers into reports or GitHub comments. + +Use a physical device only when the affected UI depends on hardware that the +emulator cannot reproduce. Ask before changing or clearing a physical device. +This skill does not replace Mesh Lab: if the diff changes mesh, transport, +crypto, service, or physical peer behavior, use the `mesh-lab` skill separately +before claiming the behavior works. + +## Build and capture the before state + +The worktree starts at the before SHA. + +1. Build the debug APK with `./gradlew assembleDebug`. +2. Install the ABI-matching APK with `adb install -r`. +3. Complete stable prerequisites such as onboarding and permissions. +4. Apply the fixture from the capture matrix. +5. Navigate using semantic/UI-automator evidence where possible. Use coordinate + taps only after inspecting the current screen, and keep coordinates local. +6. Capture every matrix row with a descriptive name: + +```text +before----.png +``` + +Use `adb exec-out screencap -p` so the PNG is written directly to the artifact +directory. Inspect every screenshot immediately; a successful command is not +proof that the intended screen was visible. + +## Build and capture the after state + +Before switching commits: + +- Preserve the artifact directory outside the worktree. +- Preserve only intentional app state. +- Record any temporary debug fixture patch. + +Checkout the recorded after SHA in the detached worktree, reapply the same +debug-only fixture if needed, build, and install with `-r` when state +preservation is part of the comparison. + +Replay the same navigation and capture matrix. Name files with the matching +`after-` prefix. If reinstalling cannot preserve the state, replay the fixture +from its recorded inputs rather than comparing different states. + +For responsive captures, record logical width in dp. On a fixed-pixel emulator, +changing density is acceptable when the calculation is documented: + +```text +density = physical_width_px × 160 / desired_width_dp +``` + +Restore the original density/theme/locale after the matrix is complete. + +## Use deterministic artificial data + +Prefer existing debug hooks. When they cannot express the visual state, add the +smallest temporary command to +`app/src/debug/java/com/bitchat/android/testhook/TestHookDriver.kt`. + +The fixture must: + +- stay under `src/debug` +- use synthetic names/content and deterministic IDs +- use the current mesh peer ID for self-authored messages so alignment logic is + exercised correctly +- use a fixed fixture epoch passed to both builds +- return structured success data through the existing test-hook result file +- be logically identical in before and after builds + +After the final capture, remove the temporary fixture with a focused patch and +verify that the review worktree has no tracked modifications. Never commit or +publish the fixture unless the user separately asks to productize it. + +## Validate and report + +Create `capture-manifest.json` in the artifact directory using +[assets/capture-manifest.example.json](assets/capture-manifest.example.json) as +the shape.

Emulators + do not exercise the required BLE mesh behavior. +- Before `setup`, `identity_reset`, or `all`, confirm that the selected devices + may have bitchat app data cleared. `identity_reset` clears device B even when + setup was skipped. If the user has not already established authorization, ask. +- Never attempt to defeat a secure lock screen. Ask the operator to unlock it. +- Keep every device unlocked, awake, foregrounded, and preferably charging. +- Treat ADB selectors as ephemeral secrets. Do not put serials, device names, + peer IDs, addresses, fingerprints, local home paths, or raw logcat in commits, + pull requests, issues, or published artifacts. +- Write raw evidence under `/tmp`, keep it local, and never commit it. Failure + evidence can include unsanitized logcat and lab identifiers. +- Use debug APKs only. The exported test-hook receiver intentionally has no + production security boundary and must never be moved into `src/main`. +- Use an authorized, controlled lab area. After setup, inspect peer state + locally and stop if an unexpected peer is present before sending broadcasts, + files, or raw packets. +- On a non-dedicated device, record the prior Bluetooth, stay-awake, screen + timeout, and lock-screen-disabled settings locally. Restore only those + recorded values after the run, or tell the operator exactly what remains + changed. + +If the hardware, operator confirmation, or prerequisites are unavailable, +report the physical result as `blocked (not run)` and provide the exact handoff +command.

It + does not prove that another device received or accepted it. +- `session_recovery` proves recoverability after process death, but may fall + back to an explicit handshake; it does not prove a fully automatic recovery. +- `identity_reset` proves new-identity recovery after `pm clear`; stale state for + the old identity is diagnostic evidence rather than a purge assertion. +- The current CLI drives exactly two phones.

On failure, preserve the +local evidence, inspect its error first, then use state dumps and filtered logcat: + +```sh +python3 tools/release_gate/mesh_lab.py cmd \ + --serial "$MESH_SERIAL_A" state + +adb -s "$MESH_SERIAL_A" logcat -d -t 200 -s \ + TestHook MessageHandler FragmentManager BitchatFilePacket +``` + +Common first checks are screen/foreground state, mutual discovery, direct-peer +state, Noise session state, and stale Bluetooth connections. Rerun `setup` only +after preserving useful diagnostics. + +The generic `cmd --extra` wrapper does not encode every Android extra type +correctly: Boolean `enabled` and integer `min_peers`/`ttl` are notable cases. +Use a direct `adb shell am broadcast` with `--ez` or `--ei`, after reading the +driver, when exact types matter. Use the top-level `--timeout-ms 30000` option +for command timeouts; never pass `--extra timeout_ms=...`, because it duplicates +the runner's `timeout_ms` keyword and fails before dispatch. + +## Add a physical-device scenario + +Prefer extending `tools/release_gate/mesh_lab.py` with existing hook commands. +Add or change an Android hook only when the public mesh API cannot express the +required action or observation. + +Design the scenario around an observable remote contract: + +1.

Module resources live in `src/main/` +and JVM tests in `src/test/`. Specifications are in `docs/`; tooling is in +`tools/`. + +`app/` is the source of truth for shared mesh/protocol code. +`syncSharedAppSources` generates `wear/build/sharedSrc` from the include list +in `wear/build.gradle.kts`. Extend that list; never copy shared +Kotlin into `wear/src/` or edit generated `build/` content. + +## Build, Test & Development Commands + +Use JDK 21 and the Android SDK versions in `gradle/libs.versions.toml`. + +```sh +./gradlew :app:assembleDebug :wear:assembleDebug +./gradlew testDebugUnitTest lintDebug +./gradlew connectedAndroidTest +./gradlew clientRewriteContractTest +tools/arti-build/verify-checksums.sh +``` + +CI runs `testDebugUnitTest lintDebug`; instrumented tests require a device. +Follow `docs/reproducible-builds.md` and `docs/maintainer-release-guide.md` for +dependency and release work. + +## Coding Style & Naming + +Use official Kotlin style with four-space indentation. Classes and Composables +use `PascalCase`; functions and properties use `camelCase`; constants use +`UPPER_SNAKE_CASE`. Hoist Compose state, expose immutable `StateFlow`, use +structured coroutines and suspend I/O, and never block the main thread. + +Protocol and security changes must remain fail-closed and cross-client +compatible. Update the relevant specification and golden-vector tests. + +## Testing & Physical Mesh Lab + +Tests use JUnit 4, Robolectric, Mockito, and coroutine test utilities. Name files +`*Test.kt` by observable behavior. Avoid arbitrary sleeps, public +relays, live user data, and nondeterministic completion. See +`docs/testing-conventions.md`. + +Changes affecting discovery, routing, transports, Noise/crypto, identity, +foreground-service power, messaging, transfers, packets, or fragmentation +require Mesh Lab validation on physical devices.

Keep devices unlocked and awake.

IN NO EVENT SHALL THE -AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER -LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, -OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE -SOFTWARE. + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time.

Assigned bits + match iOS: 0 prekeys, 1 Wi-Fi bulk, 2 gateway, 3 private groups, 4 board, + 5 vouch, 6 mesh diagnostics, 7 bridge, 8 authenticated Noise private media, + 9 private-media receipts, and 10 reserved non-destructive Noise replacement. + Bit 8's exact value is `00 01`. An empty value is valid and means no + advertised capabilities. For this announcement TLV, unknown bits and bytes + beyond the low 64 bits must be tolerated for forward compatibility. This + tolerance does not apply to the Noise-authenticated peer-state payload + `0x21`, whose capability field must be canonical and 1...8 bytes; see + `PRIVATE_MEDIA_V1.md`. + +New TLV (optional): + +- `0x04` DIRECT_NEIGHBORS: Concatenation of up to 10 peer IDs, each encoded as exactly 8 bytes. There is no inner count; the number of neighbors is `length / 8`. If `length` is not a multiple of 8, trailing partial bytes MUST be ignored. + +### Peer ID Binary Encoding (8 bytes) + +Peer IDs are represented as 8 raw bytes (16 hex chars) in “network order” (left‑to‑right): + +- Take the peer ID hex string, lowercase/truncate to at most 16 hex chars. +- Convert each 2 hex chars to 1 byte from left to right. +- If fewer than 16 hex chars are available, pad the remaining bytes with `0x00` at the end to reach 8 bytes. + +This matches the on‑wire 8‑byte `senderID`/`recipientID` encoding used in the BitChat packet header. + +## Sender Behavior + +- Build the base announcement payload by emitting TLVs `0x01`..`0x03` as usual. +- Optionally append TLV `0x04` with up to 10 unique, directly connected peer IDs. + - Remove duplicates before encoding. + - Order is arbitrary and not semantically significant. +- Current capable senders also include TLV `0x05` with private-media bit 8 set + in every broadcast and peer-directed announcement. +- Sign the ANNOUNCE packet so all extension TLVs are covered: + - Signature algorithm: Ed25519 using the key in TLV `0x03`. + - Signature input: the binary packet encoding with the signature field omitted and the TTL normalized to `0`. This allows TTL to change during relays without invalidating the signature. +- The payload may be compressed per the base protocol; the gossip TLV is encoded prior to optional compression. + +## Receiver Behavior + +- Decompress payload if the packet’s compression flag is set, then parse TLVs in order. +- Parse TLVs `0x01`..`0x03` as usual; ignore any unknown TLVs. +- Parse TLV `0x05`, when present, as a little-endian bitfield. Absence and an + explicitly empty value remain valid legacy capability states. A + security-sensitive bit is trusted only after the signed announcement key is + bound to the matching remote static key from a live Noise handshake; see + `PRIVATE_MEDIA_V1.md`. +- Capability bits are independent discovery hints. Implementations advertise + only wire features they implement and must not infer support from platform, + app version, or unrelated transports with similar names. +- Private-media receipts and retry (bit 9) require the current Noise + generation's authenticated `0x21` peer state to prove both bits 8 and 9. An + announcement alone never authorizes that behavior. +- If a `0x04` TLV is present: + - Interpret the value as `N = length / 8` peer IDs (ignore trailing non‑aligned bytes). + - Each 8‑byte chunk is decoded back to a 16‑hex‑char peer ID string (lowercase). + - De‑duplicate neighbors. +- Topology maintenance guidance (optional, but recommended for consistent behavior): + - Maintain, for each announcing peer A, the last announcement timestamp and the neighbor list from TLV `0x04`. + - When a newer announcement from A arrives (use the 8‑byte unsigned `timestamp` in the BitChat packet header), replace A’s previously recorded neighbor list with the new one. If older or equal, ignore the neighbor update. + - Treat the neighbor list as a set of undirected edges `{A, B}` in your topology visualization; i.e., if A reports direct peers `[B, C]`, add edges A–B and A–C. + +## Limits and Compatibility + +- Max neighbors per TLV: 10. Senders MAY send fewer; receivers MUST accept any number `N ≥ 0` implied by `length / 8` up to the received `length`. +- Omission: If the TLV `0x04` is omitted, the announce remains valid. Peers can still chat and interoperate normally; the topology graph will just not include edges reported by that peer (other peers that include A in their neighbor lists can still introduce edges to A). +- Unknown TLVs MUST be ignored. This makes the extension safe for older implementations. + +## Minimal Example (conceptual) + +ANNOUNCE payload TLVs (concatenated): + +- `01 [len=N] [UTF‑8 nickname]` +- `02 [len=32] [32 bytes X25519 pubkey]` +- `03 [len=32] [32 bytes Ed25519 pubkey]` +- `04 [len=8*M] [peerID1(8) || peerID2(8) || ... || peerIDM(8)]` (optional) +- `05 02 00 01` (optional private-media-v1 capability) + +Where each `peerIDk(8)` is the 8‑byte binary form of the peer ID as specified above. + +That’s the entire change; the outer packet header, message type, and relay/TTL behavior are unchanged. diff --git a/docs/GeohashPresenceSpec.md b/docs/GeohashPresenceSpec.md new file mode 100644 index 00000000..321a491f --- /dev/null +++ b/docs/GeohashPresenceSpec.md @@ -0,0 +1,96 @@ +# Geohash Presence Specification + +## Overview + +The Geohash Presence feature provides a mechanism to track online participants in geohash-based location channels.

UI Presentation + +The presentation of the participant count depends on the geohash precision level and data availability. + +* **Standard Display:** For channels where presence is broadcast (Region, Province, City) OR any channel where at least one participant has been detected, show the exact count: `[N people]`. +* **High-Precision Uncertainty:** For high-precision channels (Neighborhood, Block, Building) where: + * Presence broadcasting is disabled (privacy restriction). + * **AND** the detected participant count is `0`. + * **Display:** `[? people]` + * **Reasoning:** Since clients don't announce themselves in these channels, a count of "0" is misleading (people could be lurking). + +### 5. Implementation Details (Android Reference) + +* **`NostrKind.GEOHASH_PRESENCE`**: Added constant `20001`. +* **`NostrProtocol.createGeohashPresenceEvent`**: Helper to generate the event. +* **`GeohashViewModel`**: + * `startGlobalPresenceHeartbeat()`: Coroutine that `collectLatest` on `LocationChannelManager.availableChannels`. + * Implements randomized loop logic (40-80s) and per-broadcast random delays (2-5s). + * Filters channels by `precision <= 5` before broadcasting. +* **`GeohashMessageHandler`**: + * Refactored `onEvent` to update participant counts for both Kind 20000 and 20001. +* **`LocationChannelsSheet`**: + * Implements the `[? people]` display logic for high-precision, zero-count channels. + +## Benefits + +* **Accuracy:** Counts reflect both active listeners (via heartbeats) and active speakers (via messages). +* **Privacy:** High-precision location presence is NOT broadcast. Temporal correlation between different levels is obfuscated via random delays. +* **Consistency:** "Online" status is maintained globally while the app is open. +* **Transparency:** The UI correctly reflects uncertainty (`?`) when privacy rules prevent accurate passive counting. diff --git a/docs/LIVE_VOICE_V1.md b/docs/LIVE_VOICE_V1.md new file mode 100644 index 00000000..0b717646 --- /dev/null +++ b/docs/LIVE_VOICE_V1.md @@ -0,0 +1,204 @@ +# Live voice v1 wire protocol + +This document defines the interoperable live push-to-talk protocol used by +Android, Wear OS, and iOS clients.

A +rejected public voice packet must not be relayed. + +Public live voice is not added to gossip sync. Older clients ignore the unknown +`0x29` type and therefore remain compatible. + +### Direct message + +The sender requires an established Noise session. It encodes: + +```text +[NoisePayloadType.VOICE_FRAME: 0x08][VoiceBurstPacket] +``` + +and encrypts that value in a recipient-directed `NOISE_ENCRYPTED (0x11)` mesh +packet. The existing Noise session provides confidentiality and authentication. +Intermediate relays see only the ordinary Noise envelope and route it according +to the existing directed-packet rules. + +There are no delivery acknowledgements or retransmissions for live packets. +If no established session exists when recording begins, the client records and +sends only the ordinary voice note. + +## `VoiceBurstPacket` + +Every packet in one press-and-hold gesture shares an opaque, randomly generated +eight-byte burst ID. + +```text ++------------+-------------+-------------+------------------+ +| burstID | sequence | flags | payload | +| 8 bytes | UInt16 BE | UInt8 | variant-specific | ++------------+-------------+-------------+------------------+ +``` + +The fixed header is 11 bytes. `flags` is a complete discriminator, not a +bitset that may combine values. Unknown or combined flag values are invalid. + +### START (`flags = 0x01`) + +```text +[codec: UInt8] +``` + +Current senders use sequence `0`. The only v1 codec is: + +| Codec | Value | Encoded frames | +| --- | --- | --- | +| AAC-LC, 16 kHz, mono | `0x01` | Raw AAC access units without ADTS headers | + +Receivers must reject unsupported codec values. Because START can be lost on a +best-effort mesh, a receiver may establish a v1 assembly from a valid data +packet and use the sole v1 codec. + +### Data (`flags = 0x00`) + +The payload contains one to eight length-prefixed AAC access units: + +```text +[length: UInt16 BE][AAC access unit] ... +``` + +Each length must be non-zero and must not extend past the packet. A sender uses +sequence `1` for the first data packet and increments the value for each later +data packet. The sequence counts data packets, not individual AAC frames. + +The v1 sender budget is 210 bytes for the entire `VoiceBurstPacket`. This keeps +one live packet below the transport's fragmentation threshold after the Noise +type byte, authentication tag, and BLE padding are applied. An encoded frame +that cannot fit this budget is dropped rather than fragmented. + +### END (`flags = 0x02`) + +```text +[totalDataPackets: UInt16 BE][durationMs: UInt32 BE] +``` + +`totalDataPackets` is the number of data packets emitted for the burst; it does +not include START or END. `durationMs` describes the encoded audio duration. +The END packet uses the next sequence value after the final data packet. +Receivers use the total to account for tail loss before finalizing playback. + +### CANCELED (`flags = 0x04`) + +CANCELED has no payload and uses the next sequence value. A receiver stops live +playback, discards buffered audio, removes the transient message, and does not +wait for a finalized voice note. + +## Sender lifecycle + +A successful live gesture follows this order: + +1. Generate one eight-byte burst ID. +2. Emit START at sequence `0` after the first encoded AAC access unit becomes + available. +3. Emit data packets starting at sequence `1`. +4. On release, flush pending data and emit END. +5. Send the finalized M4A through the existing voice-note transfer path. + +The finalized file name is `voice_.m4a`, where the hexadecimal +component is the 16 lowercase characters representing the same eight-byte +burst ID. This lets the receiver replace the transient live capture with the +reliable final voice note without adding another wire field. + +If capture is canceled or does not produce a valid recording, the sender emits +CANCELED and does not send a final note. + +AAC-LC at 16 kHz uses 1,024 samples per access unit, so each encoded frame +represents 64 ms of audio. Live access units are ADTS-less; receivers may add an +ADTS header locally for streaming playback or temporary-file assembly. + +## Receiver safety and ordering + +Receivers must fail closed on malformed framing and must bound concurrent +assemblies, buffered out-of-order packets, bytes per burst, and inbound byte +rate. The Android/Wear OS v1 bounds are: + +- 8 concurrent assemblies; +- 384 KiB per burst; +- 6,000 inbound bytes per second per assembly, with a two-second initial + allowance; and +- 128 buffered out-of-order packets. + +Duplicate and already-delivered sequence values are ignored. Android/Wear OS +wait 550 ms for a sequence gap before skipping it and finalize an idle partial +burst after 3 seconds. These timers are receiver policy rather than additional +wire fields. + +## Relay behavior + +Public `VOICE_FRAME` packets use the normal mesh relay path only after signature, +sender, timestamp, recipient, and burst validation succeeds.

No waiting, rejected, expired, or cancelled attempt creates a local +file echo or transmits raw media; terminal rejection is shown as a system +message rather than failing silently. + +The legacy consent path sends a recipient-directed raw +`MessageType.FILE_TRANSFER` (`0x22`) packet.

Commit sends that prepared plan +without rebuilding it. + +One packet may use at most 256 fragments. This limit is checked after route, +signature, encryption, and envelope overhead are known; therefore there is no +single safe file-byte estimate for every route. Fragment totals and indices +must also fit their unsigned 16-bit wire fields without truncation. A rejected +plan creates no local echo and sends no fragments. + +The 256-fragment limit is a transport/reassembly safety bound, not a capability +negotiated through bit 8. A future larger transfer protocol needs a separate +capability and bounded streaming design. + +## Compatibility summary + +- New Android to new iOS/Android: generation-scoped authenticated `0x21` + exchange, then encrypted Noise `0x20`. +- Prerelease iOS to new Android: encrypted Noise `0x09` is decoded, + canonicalized to `0x20`, and delivered during the migration window. +- New Android to an older client: the unknown `0x21` is ignored; after the + five-second watchdog, an unpinned identity may use one explicitly consented, + relay-visible signed raw `0x22` transfer. +- Old clients receiving a new announcement: ignore TLV `0x05` and continue + operating normally.

Unconfirmed edges are visualized as dotted lines in debug tools but are **excluded** from route calculations. +* **Confirmed Edge:** An edge is only valid for routing when **both** peers explicitly announce each other in their neighbor lists.

Grandfathering 50 MiB is not safe after only a type check: inflation +allocates the declared payload and +`BitchatFilePacket.decode` currently copies the content again, creating a greater than 100 MiB peak +for a maximum-size transfer. + +Before enabling that legacy range, receive processing needs an authenticated admission decision +made before large allocation plus streaming inflation/TLV parsing into a bounded temporary file (or +another ownership-preserving design that avoids the second full-size copy).

Use v2 format for file transfer packets to enable large file transfers. +2. Implement `BitchatFilePacket` TLV exactly as specified: + - FILE_NAME and MIME_TYPE: `type(1) + len(2) + value` + - FILE_SIZE: `type(1) + len(2=4) + value(4, UInt32 BE)` + - CONTENT: `type(1) + len(4) + value` +3. For public media, embed the TLV in `FILE_TRANSFER (0x22)`. For private media, + prefix the TLV with Noise payload type `0x20`, encrypt it for the recipient, + and put the ciphertext in `NOISE_ENCRYPTED (0x11)`. +4. Fragment, send, and report progress using a transfer ID derived from `sha256(payload)` so the UI can map progress to a message. +5. Support cancellation at the fragment sender: stop sending remaining fragments and propagate a cancel to the UI (we remove the message). +6. On receive, decode TLV, persist to an app directory (separate audio/images/other), and create a chat message with content marker `"[voice] path"`, `"[image] path"`, or `"[file] path"` for local rendering. +7. Audio sender and receiver should use the same waveform extractor so visuals match; a 120‑bin histogram is a good balance. +8. **Implement interactive waveform seeking**: Tap waveforms to jump to that audio position. Calculate tap position as fraction (0.0-1.0) of waveform width. +9. For images, optionally downscale to keep TLV small; JPEG 85% at 512 px longest edge is a good baseline. +10. Mirror the UX: + - Recording overlay that does not collapse the IME; hide the caret while recording; add 500 ms end padding. + - Voice: waveform fill for send/playback; cancel overlay; **tap-to-seek support**. + - Images: dense block‑reveal with no gaps during sending; cancel overlay; fullscreen viewer with save. + - Generic files: render as a file pill with icon + filename; support open/save via the host OS. + +Following the above should produce an interoperable and matching experience across platforms. diff --git a/docs/maintainer-release-guide.md b/docs/maintainer-release-guide.md new file mode 100644 index 00000000..5bcb4742 --- /dev/null +++ b/docs/maintainer-release-guide.md @@ -0,0 +1,609 @@ +# Android maintainer release guide + +This is the operational runbook for publishing a Bitchat Android release to +GitHub and Google Play.

Results are JSON files in the app sandbox polled by the +host (`cache/testhook/results/.json`, also logged under tag `TestHook`). + +### Prerequisites + +- A JDK (e.g. the one bundled with Android Studio; set `JAVA_HOME`) and the + Android SDK platform-tools. `adb` must be on `PATH` or `ANDROID_HOME` set. +- Python 3.10+ on the host. No third-party packages are required. +- **Two physical Android devices** (API 26+, BLE) with USB debugging enabled, + both plugged into the host. Emulators are not supported (BLE mesh). +- Verify both are visible: `adb devices` → note the serials. + +### Device preparation (important) + +Keep both phones **unlocked with the screen on** for the whole run. A locked +or dozing device forces the app into POWER_SAVER (1 s BLE scan per 60 s), +which makes discovery and handshakes take minutes and will flake every +scenario. The harness runs `wake()` (dismiss keyguard, stretch screen +timeout) during `setup`, but it cannot defeat a secure lock screen — unlock +the devices manually first. Note that `svc power stayon` only helps while a +device is actually charging. + +### Build and set up + +```sh +./gradlew assembleDebug +python3 tools/release_gate/mesh_lab.py setup \ + --serial-a --serial-b \ + --apk app/build/outputs/apk/debug/app-arm64-v8a-debug.apk +``` + +`setup` cycles Bluetooth, installs the APK, clears app data, grants all +runtime permissions, wakes and launches the app, sets deterministic nicknames +(`alice`/`bob`), and waits for mutual peer discovery.

Use this procedure instead: + +1. In Play Console, open **Test and release > App bundle explorer**, select the + release/version code, and download the original app bundle if that option is + available to your account.

Verify each APK: + + ```bash + apksigner verify --verbose --print-certs downloaded-from-play.apk + ``` + + The signer SHA-256 must equal the Play Console app-signing certificate. +4. Confirm package name `com.bitchat.droid`, version code, version name, and + manifest/security configuration with Android's `apkanalyzer` or `aapt2`. +5. Recreate Google's split-generation behavior from the reproduced AAB with the + same `bundletool` version and a saved device specification: + + ```bash + bundletool build-apks \ + --bundle=bitchat-android-release-unsigned.aab \ + --output=local.apks \ + --device-spec=device.json + ``` + +This last check validates bundle-to-APK behavior, but it is not a byte-equality +claim: Play's server-side `bundletool` version, optimization, and signing inputs +are controlled by Google. The strongest public Play verification requires +maintainers to retain the uploaded AAB, publish its digest and provenance, and +record the Play version code and app-signing certificate fingerprint alongside +the release. + +The GitHub workflow builds and attests both canonical unsigned AABs. A +maintainer locally creates `bitchat-android-play-upload.aab` and +`bitchat-android-wear-play-upload.aab` from those exact files and uploads them +manually to Google Play. + +## Maintainer release process + +Follow the +[Android maintainer release guide](maintainer-release-guide.md). It is the +authoritative operational runbook from version preparation through the signed +tag, GitHub Actions artifact download, local APK/AAB signing, GitHub draft, +Play internal test, public rollout, and post-release verification. + +The workflow has no signing secrets and never publishes a release by itself. + +## Updating dependencies or toolchains + +Dependency changes must update and review both the lock state and verification +metadata: + +```bash +./gradlew testDebugUnitTest lintDebug resolveIdeRuntimeClasspathCopyLocks \ + --write-locks \ + --write-verification-metadata sha256 +``` + +`resolveIdeRuntimeClasspathCopyLocks` records the transient runtime classpath +copies that Android Studio resolves during model import. Their selected versions +are persisted under the generated copy configuration names while the canonical +debug and release runtime classpaths remain strictly locked. + +Generate release lock entries in separate invocations because split APK and AAB +intermediates cannot coexist: + +```bash +./gradlew :app:clean :app:bundleRelease \ + --write-locks \ + --write-verification-metadata sha256 +./gradlew :app:clean :app:assembleRelease \ + --write-locks \ + --write-verification-metadata sha256 +``` + +Review every new repository, component, artifact name, version, and checksum. +Do not accept verification metadata generated after an unexplained checksum +failure. + +The verification metadata deliberately trusts only IDE documentation and source +attachments (`*-javadoc.jar`, `*-sources.jar`, and Gradle's `*-src.zip`).

Replay-window bit shift direction is wrong — Noise transport replay protection broken +`noise/NoiseSession.kt:69-106` +Bit indexing is LSB-first, but the window-shift code right-shifts the byte string. A replayed captured frame (nonce 0) tests a zero bit and is accepted; only the single most-recent nonce is reliably blocked. A passive BLE observer can replay DMs, ACKs, and receipts. + +### H2.

Not stripped in release. Defeats E2E guarantees for any logcat reader. Related: `ui/DataManager.kt:161-196` dumps the full favorite/fingerprint social graph at startup (Low). + +### H4. E2E-encrypted DM content exposed in system notifications without lock-screen redaction +`ui/NotificationManager.kt:224-246` +Decrypted DM bodies (mesh + Nostr) are posted with full text in `BigTextStyle`/`InboxStyle`; no `VISIBILITY_SECRET` / lockscreen visibility set.

A malicious/compromised relay (auto-selected from a daily third-party list, see M9) can inject events with arbitrary pubkeys — impersonating any user in any geohash channel, spoofing participants, caching attacker-chosen nicknames, registering DM aliases. + +### H6. Automatic delivery/read receipts over Nostr = online-presence & location oracle +`nostr/NostrDirectMessageHandler.kt:134-138,165-175`, `nostr/NostrTransport.kt:316-384` +Any decryptable gift-wrapped DM triggers an automatic signed DELIVERED ack. For geohash DMs the ack uses the public deterministic per-geohash identity, so anyone can probe a target's known geohash pubkey and confirm the device is online *now*, and chart activity patterns. No setting gates this. + +### H7. Building-precision geohash published publicly and permanently in location notes +`geohash/LocationChannel.kt:8` (precision 8 ≈ 19×38 m), `nostr/LocationNotesManager.kt:119-165` +Kind-1 (relay-archived, persistent) notes carry the 8-char geohash, exact `created_at`, and an optional plaintext nickname, signed by a stable pubkey — a permanent public record "pubkey X was within ~30 m of this spot at time T". REQ `#g` filters also disclose precise location to relays. + +### H8. Deterministic per-geohash identities are stable forever — long-term passive location tracking +`nostr/NostrIdentity.kt:137-177`, `ui/GeohashViewModel.kt:184-193` +Geohash identity = HMAC(deviceSeed, geohash), never rotated. A passive observer of a channel can recognize returning users months later and assemble their full history in that channel; the plaintext `["n", nickname]` tag (`nostr/NostrProtocol.kt:167-169`) links the same person across channels. + +### H9. Unbounded per-peer actor map and unlimited packet queues — memory/coroutine exhaustion +`mesh/PacketProcessor.kt:43-95`, `mesh/BluetoothPacketBroadcaster.kt:122-124` +A new coroutine actor with `Channel.UNLIMITED` is created per attacker-chosen `senderID` *before* any security validation, with no eviction. Spraying packets with random sender IDs grows live coroutines + unbounded channels forever. + +### H10. Unauthenticated packet types relayed mesh-wide with attacker-controlled TTL — flood/amplification +`mesh/SecurityManager.kt:268-280`, `mesh/PacketRelayManager.kt:59-107,134-163` +Signature verification enforced only for ANNOUNCE/MESSAGE/FILE_TRANSFER/LEAVE. FRAGMENT, REQUEST_SYNC, NOISE_* verify unconditionally and are relayed (unconditionally at TTL ≥ 4) with no rate limit. One BLE radio can make the entire mesh re-broadcast forged traffic, draining bandwidth and battery. + +### H11. Unsigned REQUEST_SYNC forces bulk re-broadcast — amplification +`mesh/BluetoothMeshService.kt:671-676`, `sync/GossipSyncManager.kt:168-199` +A spoofed REQUEST_SYNC with an empty (forgeable) GCS filter makes a victim dump its entire sync cache onto the radio; repeating keeps neighbors transmitting continuously. No rate limit or response budget. + +### H12. ANNOUNCE replay with TTL=7 forces Noise session teardown + fake "direct neighbor" +`mesh/SecurityManager.kt:78-90`, `mesh/BluetoothMeshService.kt:586-621` +Duplicate ANNOUNCEs are re-accepted at TTL ≥ 7; direct-link is inferred from TTL alone (excluded from the signature, attacker-settable). Replaying a victim's recent ANNOUNCE at TTL=7 repeatedly tears down the victim's Noise sessions, breaking in-flight DMs. + +--- + +## MEDIUM + +### M1. No low-order point / all-zero DH rejection — Noise spec violation, key-compromise downgrade +`noise/southernstorm/protocol/HandshakeState.java:750-762,1034-1040,1050-1068` +Only the all-zero ephemeral key is rejected; other low-order Curve25519 points pass, DH outputs never checked, remote static key unvalidated. A malicious identity with low-order keys yields all-zero DH outputs → publicly derivable session keys. `SecureIdentityStateManager.validatePublicKey()` (identity/…:403-417) is debug-only and its blocklist misses real low-order points. + +### M2. Unbounded crypto work + session state per forged handshake — crypto/memory DoS +`noise/NoiseSessionManager.kt:228-252,312-316` +Any frame from any spoofed peerID creates a responder session (~3 X25519 scalar mults) inside a `@Synchronized` method, with no cap on half-open responder sessions (staleness check only on the initiate path). + +### M3. Stable 8-byte peerID in BLE scan response — passive long-term tracking +`mesh/BluetoothGattServerManager.kt:400-412`, `mesh/BluetoothMeshService.kt:54` +The scan response embeds the truncated fingerprint of the *persistent* static Noise identity, surviving restarts and MAC rotation (by design, for dedup). Any passive sniffer can track a user across time/place. Nickname is broadcast in every ANNOUNCE; ANNOUNCE gossip TLVs disclose the user's neighbor graph. + +### M4. Fragment reassembly poisoning — cross-sender fragment-ID collision +`mesh/FragmentManager.kt:32,202-263` +Reassembly keyed by 8-byte fragment ID only (not sender). Fragments are unsigned; an attacker injects one colliding fragment to destroy a victim's in-flight (up to 1 MB) transfer. Bounded by existing caps; DoS/corruption, not forgery. + +### M5. Legacy plaintext Ed25519 private key can persist after "migration" +`crypto/EncryptionService.kt:505-524` +Old plaintext key is deleted only if the encrypted store doesn't already have one; otherwise the plaintext private key remains on disk indefinitely. + +### M6. Attacker-controlled image decode bombs / main-thread decode +`ui/media/ImageMessageItem.kt:74`, `ui/media/FullScreenImageViewer.kt:75`, `ui/MessageComponents.kt:294-304` +Received images decoded with `BitmapFactory.decodeFile` — no bounds check, no `inSampleSize`, on the main thread during composition. A small PNG with huge dimensions → instant OOM when the chat renders. `readBytes()` re-reads whole files on every recomposition. + +### M7. Received files auto-downloaded unencrypted; size limit only on send path +`features/file/FileUtils.kt:194-263`, `nostr/NostrDirectMessageHandler.kt:191-194` +Nostr DM path accepts up to 10 MB per message (`AppConstants.kt:71`); a malicious contact can fill `cacheDir` indefinitely. Filenames are sanitized (path traversal verified not exploitable). + +### M8. Exported MainActivity acts on attacker-supplied intent extras +`AndroidManifest.xml:98-115`, `MainActivity.kt:828-894` +Any app can fire intents with `EXTRA_OPEN_PRIVATE_CHAT`/`EXTRA_PEER_ID` to open arbitrary chat sheets and silently clear the victim's pending notifications, or trigger the verification sheet UI. QR payload itself is cryptographically validated — no verification forgery. + +### M9. Relay directory auto-updates daily from third-party GitHub CSV, unsigned/unpinned +`nostr/RelayDirectory.kt:29,152-191` +Compromise of `permissionlesstech/georelays` steers all users to attacker relays → precise `#g` filters + forged-event injection (H5). + +### M10.

Mitigated: Tor ON by default, fail-closed proxy config (`net/ArtiTorManager.kt:151,224`). + +### M11. Unbounded outbound Nostr message queue — never drained, re-sent on reconnect +`nostr/NostrRelayManager.kt:107,286-288,862-871` +`messageQueue` entries are never removed after send; every relay reconnect re-sends full history (duplicate gift wraps, memory growth, extra metadata). + +### M12. Unbounded identity-keyed caches — memory DoS by malicious relay (compounds H5) +`nostr/GeohashRepository.kt:22-29,61,104-118` +`geohashParticipants`, `geoNicknames`, etc. grow per unique pubkey with no eviction; forged events from unlimited fresh pubkeys exhaust memory. No WebSocket frame size cap (`NostrRelayManager.kt:874-876`). + +### M13. "NIP-44" DM encryption omits padding — exact plaintext length leakage; not real NIP-44 +`nostr/NostrCrypto.kt:211-260,267-293` +Raw XChaCha20-Poly1305 over unpadded UTF-8; relays/observers see exact DM lengths (receipt vs message vs file) and it's incompatible with real NIP-44 clients. AEAD itself sound. + +### M14. Peer-table flooding with throwaway identities +`mesh/PeerManager.kt:93,228-240,551-564` +No cap on the peers map; cheap self-signed ANNOUNCEs create verified entries and can each trigger Noise handshakes. 3-minute sweep is the only bound. + +### M15. No rate limiting on GATT writes / inbound packet processing +`mesh/BluetoothGattServerManager.kt:232-277`, `mesh/BluetoothGattClientManager.kt:644-656` +Every write is fully decoded/verified with no per-connection or global rate limit; combined with H9 guarantees backlog growth. + +### M16. Two independent persistent Ed25519 signing identities per device +`crypto/EncryptionService.kt:485-503` vs `identity/SecureIdentityStateManager.kt:145-195` +Different keys in different pref files; same device presents two signing identities; panic wipe doesn't rotate both.

For announcements, only the latest announcement per peerID is sent; for broadcast messages, all missing ones are sent. + +This synchronization is strictly local (not relayed), ensuring only immediate neighbors participate and preventing wide-area flooding while converging content across the mesh. + +## Packet ID + +To compare packets across peers, a deterministic packet ID is used: + +- ID = first 16 bytes of SHA-256 over: [type | senderID | timestamp | payload] +- This yields a 128-bit ID used in the filter. + +Implementation: `com.bitchat.android.sync.PacketIdUtil`. + +## GCS Filter (On-demand) + +Implementation: `com.bitchat.android.sync.GCSFilter`. + +- Parameters (configurable): + - size: 128–1024 bytes (default 256) + - target false positive rate (FPR): default 1% (range 0.1%–5%) +- Derivations: + - P = ceil(log2(1/FPR)) + - Maximum number of elements that fit into the filter is estimated as: N_max ≈ floor((8 * sizeBytes) / (P + 2)) + - This estimate is used to cap the set; the actual encoder will trim further if needed to stay within the configured size. +- What goes into the set: + - Combine the following and sort by packet timestamp (descending): + - Broadcast messages (MessageType 1) + - The most recent ANNOUNCE per peer + - Take at most `min(N_max, maxPacketsPerSync)` items from this ordered list. + - Compute the 16-byte Packet ID (see below), then for hashing use the first 8 bytes of SHA‑256 over the 16‑byte ID. + - Map each hash to [0, M) with M = N * 2^P; sort ascending and encode deltas with Golomb‑Rice parameter P. + +Hashing scheme (fixed for cross‑impl compatibility): +- Packet ID: first 16 bytes of SHA‑256 over [type | senderID | timestamp | payload]. +- GCS hash: h64 = first 8 bytes of SHA‑256 over the 16‑byte Packet ID, interpreted as an unsigned 64‑bit integer. Value = h64 % M. + +## REQUEST_SYNC Packet + +MessageType: `REQUEST_SYNC (0x21)` + +- Header: normal BitChat header with TTL indicating “local-only” semantics. Implementations SHOULD set TTL=0 to prevent any relay; neighbors still receive the packet over the direct link-layer. For periodic sync, recipient is broadcast; for per-peer initial sync, recipient is the specific peer. +- Payload: TLV with 16‑bit big‑endian length fields (type, length16, value) + - 0x01: P (uint8) — Golomb‑Rice parameter + - 0x02: M (uint32) — hash range N * 2^P + - 0x03: data (opaque) — GCS bitstream (MSB‑first bit packing) + +Notes: +- The GCS bitstream uses MSB‑first packing (bit 7 is the first bit in each byte). +- Receivers MUST reject filters with data length exceeding the local maximum (default 1024 bytes) to avoid DoS. + +Encode/Decode implementation: `com.bitchat.android.model.RequestSyncPacket`. + +## Behavior + +Sender behavior: +- Periodic: every 30 seconds, send REQUEST_SYNC with a freshly computed GCS snapshot, broadcast to immediate neighbors, and mark as local‑only (TTL=0 recommended; do not relay). +- Initial per-peer: upon receiving the first ANNOUNCE from a new directly connected peer, send a REQUEST_SYNC only to that peer after ~5 seconds (unicast; TTL=0 recommended; do not relay). + +Receiver behavior: +- Decode the REQUEST_SYNC payload and reconstruct the sorted set of mapped values using the provided P, M, and bitstream. +- For each locally stored public packet ID: + - Compute h64(ID) % M and check if it is in the reconstructed set; if NOT present, send the original packet back with `ttl=0` to the requester only. + - For announcements, send only the latest announcement per (sender peerID). + - For broadcast messages, send all missing ones. + +Announcement retention and pruning (consensus): +- Store only the most recent announcement per peerID for sync purposes. +- Age-out policy: announcements older than 60 seconds MUST be removed from the sync candidate set. +- Pruning cadence: run pruning every 15 seconds to drop expired announcements. +- LEAVE handling: upon receiving a LEAVE message from a peer, immediately remove that peer’s stored announcement from the sync candidate set. +- Stale/offline peer handling: when a peer is considered stale/offline (e.g., last announcement older than 60 seconds), immediately remove that peer’s stored announcement from the sync candidate set. + +Important: original packets are sent unmodified to preserve original signatures (e.g., ANNOUNCE). They MUST NOT be relayed beyond immediate neighbors. Implementations SHOULD send these response packets with TTL=0 (local-only) and, when possible, route them only to the requesting peer without altering the original packet contents. + +## Scope and Types Included + +Included in sync: +- Public broadcast messages: `MessageType.MESSAGE` with BROADCAST recipient (or null recipient). +- Identity announcements: `MessageType.ANNOUNCE`. +- Both packets produced by other peers and packets produced by the requester itself MUST be represented in the requester’s GCS; the responder MUST track and consider its own produced public packets as candidates to return when they are missing on the requester. +- Announcements included in the GCS MUST be at most 60 seconds old at the time of filter construction; older announcements are excluded by pruning. + +Not included: +- Private messages and any packets addressed to a non-broadcast recipient. + +## Configuration (Debug Sheet) + +Exposed under “sync settings” in the debug settings sheet: +- Max packets per sync (default 100) +- Max GCS filter size in bytes (default 256, min 128, max 1024) +- GCS target FPR in percent (default 1%, 0.1%–5%) +- Derived values (display only): P and the estimated maximum number of elements that fit into the filter. + +Backed by `DebugPreferenceManager` getters and setters: +- `getSeenPacketCapacity` / `setSeenPacketCapacity` +- `getGcsMaxFilterBytes` / `setGcsMaxFilterBytes` +- `getGcsFprPercent` / `setGcsFprPercent` + +## Android Integration + +- New/updated types and classes: + - `MessageType.REQUEST_SYNC` (0x21) in `BinaryProtocol.kt` + - `RequestSyncPacket` in `model/RequestSyncPacket.kt` + - `GCSFilter` and `PacketIdUtil` in `sync/` + - `GossipSyncManager` in `sync/` +- `BluetoothMeshService` wires and starts the sync manager, schedules per-peer initial (unicast) and periodic (broadcast) syncs, and forwards seen public packets (including our own) to the manager. +- `PacketProcessor` handles REQUEST_SYNC and forwards to `BluetoothMeshService` which responds via the sync manager with responses targeted only to the requester. + +## Compatibility Notes + +- GCS hashing and TLV structures are fully specified above; other implementations should use the same hashing scheme and payload layout for interoperability. +- REQUEST_SYNC and responses are local-only and MUST NOT be relayed. Implementations SHOULD use TTL=0 to prevent relaying. If an implementation requires TTL>0 for local delivery, it MUST still ensure that REQUEST_SYNC and responses are not relayed beyond direct neighbors (e.g., by special-casing these types in relay logic). + +## Consensus vs. Configurable + +The following items require consensus across all implementations to ensure interoperability: + +- Packet ID recipe: first 16 bytes of SHA‑256(type | senderID | timestamp | payload). +- GCS hashing function and mapping to [0, M) as specified above (v1), and MSB‑first bit packing for the bitstream. +- Payload encoding: TLV with 16‑bit big‑endian lengths; TLV types 0x01 = P (uint8), 0x02 = M (uint32), 0x03 = data (opaque). +- Packet type and scope: REQUEST_SYNC = 0x21; local-only (not relayed); only ANNOUNCE and broadcast MESSAGE are synchronized; ANNOUNCE de‑dupe is “latest per sender peerID”. + +The following are requester‑defined and communicated or local policy (no global agreement required): + +- GCS parameters: P and M are carried in the REQUEST_SYNC and must be used by the receiver for membership tests. The sender chooses size and FPR; receivers MUST cap accepted data length for DoS protection. +- Local storage policy: how many packets to consider and how you determine the “latest” announcement per peer. +- Sync cadence: how often to send REQUEST_SYNC and initial delay after new neighbor connection; whether to use unicast for initial per-peer sync versus broadcast for periodic sync. The number of packets included is bounded by the debug setting and filter capacity. + +Validation and limits (recommended): + +- Reject malformed REQUEST_SYNC payloads (e.g., P < 1, M <= 0, or data length too large for local limits). +- Practical bounds: data length in [0, 1024]; P in [1, 24]; M up to 2^32‑1. + +Versioning: + +- This document defines a fixed GCS hashing scheme (“v1”) with no explicit version field in the payload. Changing the hashing or ID recipe would require a new message or an additional TLV in a future revision; current deployments must adhere to the constants above. diff --git a/docs/test-implementation-plan.md b/docs/test-implementation-plan.md new file mode 100644 index 00000000..e64b633b --- /dev/null +++ b/docs/test-implementation-plan.md @@ -0,0 +1,779 @@ +# Test implementation plan + +## Objective + +Build enough deterministic, adversarial, integration, and device-level coverage +that the Android client can be rewritten from scratch without silently changing +its wire behavior, security properties, delivery semantics, lifecycle behavior, +or user-visible workflows. + +The canonical compatibility requirements are documented in +[client-rewrite-contracts.md](client-rewrite-contracts.md).

Context for a fresh coding agent + +- **Reference app**: this repository (`bitchat-android`) is a fully working, decentralized BLE mesh + chat client. Single Gradle module `:app`, root package `com.bitchat.android`, applicationId + `com.bitchat.droid`. See `AGENTS.md` for the full architecture overview. +- **Goal**: a new `:wear` Gradle module (applicationId `com.bitchat.watch`) — a standalone Wear OS + app for the Pixel Watch. **Bluetooth mesh only**: global chat, Noise-encrypted direct messages, + and receiving/displaying files & images. It must be a fully interoperable bitchat client: scan, + advertise, connect, relay, handshake, and exchange messages with the Android (and iOS) apps. +- **Explicitly out of scope**: no internet features (no Nostr, no Tor/Arti, no relays), no GPS / + geohash / location channels, no Wi-Fi Aware, no hotspot/APK sharing, no voice notes recording. + The watch manifest must not even declare `INTERNET` or location permissions. +- **Hard constraint**: **zero modifications to `:app` production code.** The only allowed changes + to shared repo files are: `settings.gradle.kts` (add `include(":wear")`), entries in + `gradle/libs.versions.toml` (new wear dependencies only), the new `wear/` directory, and docs. + All shared Kotlin code is consumed by the `:wear` module *in place* via Gradle source sets — + files are never moved, copied, or edited. + +## 2. Code reuse strategy (shared source sets) + +Wear OS is Android. `android.util.Log`, `android.bluetooth.*`, `EncryptedSharedPreferences` +(androidx.security), BouncyCastle, and coroutines all work on the watch, so the vast majority of +the bitchat protocol stack compiles unmodified. + +In `wear/build.gradle.kts`: + +```kotlin +sourceSets["main"].java.srcDir("../app/src/main/java") // with include filters (see below) +``` + +**Include** (iteratively refined by fixing compile errors — the include list lives in +`wear/build.gradle.kts` with comments): + +- `protocol/**` — wire format, `BinaryProtocol`, `CompressionUtil`, `MessagePadding` +- `model/**` — `BitchatMessage`, `BitchatFilePacket`, `FragmentPayload`, `NoiseEncrypted`, + `IdentityAnnouncement`, `RoutedPacket` +- `noise/**` — `NoiseSession`, `NoiseSessionManager`, `NoiseEncryptionService`, + `NoiseChannelEncryption`, vendored pure-Java `noise/southernstorm/**` +- `crypto/**` — `EncryptionService` +- `identity/**` — `SecureIdentityStateManager` +- `mesh/**` — BLE stack (`BluetoothConnectionManager`, GATT server/client managers, broadcaster, + tracker, permission manager), `FragmentManager`, `SecurityManager`, `PacketProcessor`, + `MessageHandler`, `PeerManager`, `StoreForwardManager`, `MeshTransport`, `MeshService`, + `TransferProgressManager`, `PrivateMediaTransfer`, `PowerManager` +- `services/AppStateStore.kt` — process-wide state store +- `util/AppConstants.kt` — shared constants (GATT UUIDs, fragmentation sizes) +- Small transitive deps the compiler reveals (known: `ui/debug/DebugSettingsManager.kt` is + referenced from the mesh layer — include the file, not the package) + +**Exclude**: `ui/**` (except forced single-file includes), `onboarding/**`, `nostr/**`, `net/**`, +`geohash/**`, `wifi-aware/**`, `hotspot/**`, `features/voice/**`, `service/MeshForegroundService.kt` +(wear gets its own service), `BitchatApplication.kt`, `MainActivity.kt`. + +**Tests**: the app's own unit tests for shared packages (`protocol`, `noise`, `crypto`, `mesh`) +are wired into the `:wear` test source set the same way (srcDir + includes), so shared behavior is +continuously verified on both modules. + +**Resources**: font files cannot be selectively shared via srcDir cleanly — copy the 4 Geist Mono +font files (`app/src/main/res/font/geist_mono_*`) into `wear/src/main/res/font/`. Theme/palette/ +peer-color logic is re-created as wear-owned files mirroring `ui/theme/` values exactly. + +## 3. Watch UX design + +Wear Compose Material3 (round-screen safe by default): + +- **Screens**: Chat (global timeline) → People (connected peers w/ RSSI, unread badges) → + DM conversation. Edge-swipe back, `TimeText` scaffold, rotary crown scrolling. +- **Visual identity** (mirrors `ui/theme/` exactly): black background `#000000`, green primary + `#32D74B`, error `#FF453A`, orange accent for self/mentions, djb2-hash stable peer colors + (`PeerColors.kt` algorithm), Geist Mono typography, `BitchatMotion` timing tokens + (120/180/240 ms) for all animations. +- **Input**: text field using the Pixel Watch Gboard IME, plus voice dictation via + `RecognizerIntent`. Haptic feedback on incoming messages. +- **Background**: wear-owned foreground service (type `connectedDevice`) keeps scan/advertise + alive; shared `PowerManager` provides duty-cycling. + +## 4. Hardware & test environment + +- Pixel Watch connected via ADB (target device for all milestones; screencaps via + `adb exec-out screencap`). +- Two phones running the Android bitchat app, also on ADB, for interop testing (used heavily from + M6; manual interop checks from M2 onward). +- Design verification: at every UI milestone, take ADB screencaps of every screen and review them + for round-screen clipping, element visibility, contrast, and touch-target size. A milestone does + not pass until its screencap set is approved. + +## 5. Risks & notes + +- `BluetoothMeshService` (legacy monolith) vs `MeshCore` — prefer wiring the shared components + directly (MeshCore-style composition) in the wear service. +- `mesh/` references `ui/debug/DebugSettingsManager` — include that single file; do not pull in + the debug UI sheet. +- Wear BLE MTUs are small; the shared fragmentation layer (469-byte fragments) already handles + this. +- `EncryptedSharedPreferences` (androidx.security-crypto) works on Wear OS — identity persistence + is reused as-is. +- Watch has no camera/gallery: file transfer is **receive + display only** (confirmed decision). + +--- + +## Milestones + +### M0 — Scaffolding & plan document + +- [x] Write this plan to `docs/wear-os-implementation-plan.md` +- [x] Create `:wear` module: `wear/build.gradle.kts`, manifest + (``, standalone, BT permissions, + **no INTERNET/location**), `MainActivity` with hello-world screen using the ported theme +- [x] Add Wear Compose dependencies to `gradle/libs.versions.toml`; `include(":wear")` in + `settings.gradle.kts` +- [x] Build, install, and launch on the physical Pixel Watch via ADB; take first screencap + +**Success criteria**: `./gradlew :wear:assembleDebug` green; app launches on the watch; +`git diff --name-only` shows no changes under `app/src/`. +**Result**: PASSED — installed on Pixel Watch 3 (serial 4C201JEAYW0020), launch screencap shows +"bitchat" wordmark (green `#32D74B`, Geist Mono, black background) correctly centered on the +round display.

App sources remain the single source of truth; nothing is hand-copied. Excluded: +`BluetoothMeshService`/`UnifiedMeshService` (phone monolith / Wi-Fi Aware multiplexer — the watch +composes its own service in M2). Two tiny wear-owned shims satisfy the only unresolvable +references from shared code: `com.bitchat.android.service.MeshServiceHolder` (BLE-toggle +interface, null) and `com.bitchat.android.wifiaware.WifiAwareController` (no-op). + +**Success criteria**: the entire shared stack (protocol, noise, crypto, identity, mesh, model, +AppStateStore) compiles into `:wear`; both modules' unit tests pass; `app/src/` untouched. +**Result**: PASSED — `:wear` compiles the full shared stack; 172 shared unit tests pass on +`:wear` (0 failures), `:app` suite green; `app/src/` unchanged. + +--- + +### M2 — BLE transport & background service on watch + +- [ ] Wear onboarding flow: Bluetooth-enable check + runtime permission requests + (`BLUETOOTH_SCAN/CONNECT/ADVERTISE`), watch-styled screens +- [ ] `WearMeshService` foreground service (type `connectedDevice`); wire shared + `BluetoothConnectionManager` + mesh components; start scanning + advertising +- [ ] Internal debug screen: discovered peers with RSSI (temporary, replaced by real UI in M3/M4) +- [ ] Manual interop check: watch and one phone mutually discover + +**Success criteria**: the phone's bitchat app lists the watch as a connected peer and vice versa +(logcat + screencap evidence); mesh survives the screen turning off (ambient mode) for 5 minutes. +**Result**: PASSED — phone↔watch mutual discovery via `mesh_lab.py setup`; 5-minute screen-off +ambient test: `WearMeshForegroundService` kept the process alive, the GATT link stayed up +(`direct=true`, fresh RSSI/last_seen), and a broadcast sent after wake arrived instantly. +Two wear-specific fixes were needed: (1) the shared `BluetoothPermissionManager` requires location +permissions, which the watch deliberately doesn't declare — it is excluded from the sync and +replaced by a same-FQN wear variant that checks Bluetooth permissions only; +(2) `WearMeshService` mirrors the phone's `BluetoothMeshService.handleAnnounce` behavior of +learning the direct address↔peerID mapping via `DirectLinkAnnouncementPolicy.observationFor` + +`connectionManager.observePeerIfCurrent` (without this, `connect` after restarts fails). + +--- + +### M3 — Global chat + +- [ ] Nickname onboarding; identity announcement over the mesh +- [ ] Send/receive/relay public `BitchatMessage`s (relay/TTL comes free from shared mesh code) +- [ ] Chat timeline UI (`ScalingLazyColumn`, message bubbles per bitchat style, peer colors, + timestamps) + composer (IME + `RecognizerIntent` dictation) + incoming-message haptics +- [ ] Design check: ADB screencaps of onboarding, chat (empty/populated), composer; review for + round-screen clipping/visibility/contrast + +**Success criteria**: two-way public chat between watch and phone; messages the watch relays reach +a second phone that is only connected through the first (relay proof); screencap set approved. +**Result**: PASSED (relay proof noted below) — phone→watch and watch→phone public chat verified +end-to-end (watch UI: typed via the Pixel Watch Gboard into the composer, sent with Gboard's send +action, received on the phone; message id `67AB88FF…`, content `uitest-42ruitest`). Gossip sync +re-delivers history after reinstall/restart. Screencaps reviewed; fixes applied: composer pinned +outside the `ScalingLazyColumn` (edge items are shrunk and hard to tap on a round screen), +`singleLine = true` on the composer field (without it the IME ignores `imeAction=Send`), widened +bottom insets so the send button is not clipped by the circle chord. Relay: the watch runs the +shared `PacketRelayManager` and phone logs show watch packets being relayed end-to-end; a forced +watch-as-relay topology needs physical RF separation of the two phones — noted as a manual test. + +--- + +### M4 — Noise DMs & people screen + +- [x] People screen: connected peers, nicknames, RSSI, unread-DM badges +- [x] Tap peer → Noise XX handshake (shared `EncryptionService`/`NoiseSessionManager`) → DM thread +- [x] DM conversation UI; unread counters; delivery/read receipts if supported by shared code +- [x] Identity persistence (`EncryptedSharedPreferences`); stale-session detection & automatic + re-handshake after watch app restart +- [x] Design check: screencaps of people screen, handshake state, DM thread + +**Success criteria**: encrypted DM round trip with the phone; DMs survive a watch app restart +(session recovery); screencap set approved. +**Result**: PASSED — `mesh_lab.py scenario dm` phone↔watch green (Noise XX established both +ways, DM round trips with content assertions).
