-            
-              - If your pull request adds a feature or modifies the UI, this should have an equivalent pull request in the [Element X iOS repo](https://github.com/element-hq/element-x-ios) unless it only affects an Android-only behaviour or is behind a disabled feature flag, since we need parity in both clients to consider a feature done. It will also need to be approved by our product and design teams before being merged, so it's usually a good idea to discuss the changes in a Github issue first and then start working on them once the approach has been validated.
-              - Your branch should be based on \`origin/develop\`, at least when it was created.
-              - The title of the PR will be used for release notes, so it needs to describe the change visible to the user.
-              - The test pass locally running \`./gradlew test\`.
-              - The code quality check suite pass locally running \`./gradlew runQualityChecks\`.
-              - If you modified anything related to the UI, including previews, you'll have to run the \`Record screenshots\` GH action in your forked repo: that will generate compatible new screenshots. However, given Github Actions limitations, **it will prevent the CI from running temporarily**, until you upload a new commit after that one. To do so, just pull the latest changes and push [an empty commit](https://coderwall.com/p/vkdekq/git-commit-allow-empty).`
-            })

+# BLOCKERS.md - Phase 1 Implementation Status
+
+## Task 1: Module Scaffolding ✅ COMPLETE
+
+### Completed
+- ✅ Module structure created (api/impl/test)
+- ✅ Metro DI setup following Element X patterns
+- ✅ WalletEntryPoint and WalletState APIs defined
+- ✅ PaymentFlowNode placeholder with Appyx navigation
+- ✅ FakeWalletEntryPoint for testing
+- ✅ Cardano client library dependencies added
+- ✅ ProGuard rules configured
+- ✅ Basic unit tests added
+- ✅ Pushed to Gitea phase1-dev branch
+
+---
+
+## Task 2: Key Generation + Storage ✅ COMPLETE
+
+### Completed
+- ✅ **CardanoNetworkConfig.kt** - Single object for testnet/mainnet config swap
+  - Currently configured for TESTNET (preprod)
+  - Change `NETWORK` to `CardanoNetwork.MAINNET` for production
+  - All derived values (Koios URL, explorer URL, address prefix) auto-switch
+
+- ✅ **CardanoKeyStorage** (interface + implementation)
+  - Per-session wallet isolation (key alias: `cardano_wallet_{sessionId}`)
+  - 24-word BIP-39 mnemonic generation using cardano-client-lib
+  - AES-GCM-256 encryption with Android Keystore-backed key
+  - `setUserAuthenticationRequired(true)` - biometric/PIN for every operation
+  - `setUserAuthenticationValidityDurationSeconds(-1)` - no grace period
+  - `setInvalidatedByBiometricEnrollment(true)` - invalidate on biometric change
+  - Methods: `generateWallet`, `importWallet`, `getMnemonic`, `getBaseAddress`, `getStakeAddress`, `deleteWallet`
+
+- ✅ **CardanoWalletManager** (interface + implementation)
+  - Key derivation using CIP-1852 via cardano-client-lib's Account class
+  - Path `m/1852'/1815'/0'/0/0` for external receiving address
+  - Path `m/1852'/1815'/0'/2/0` for staking key
+  - Shelley base address generation (payment + staking key hash)
+  - Uses CardanoNetworkConfig for network selection
+  - Exposes: `getAddress(sessionId)`, `getStakeAddress(sessionId)`, `getSpendingKey(sessionId)`
+
+- ✅ **SeedPhraseManager** (interface + implementation)
+  - 24-word mnemonic generation (256-bit entropy)
+  - Support for 12/15/18/21/24 word counts
+  - BIP-39 validation (checksum + wordlist)
+  - Word suggestions for autocomplete
+  - Normalization (whitespace, case)
+  - ⚠️ UI must apply `FLAG_SECURE` when displaying seed phrases (documented)
+
+- ✅ **FakeCardanoKeyStorage** for testing
+- ✅ Unit tests for SeedPhraseManager, CardanoNetworkConfig, CardanoWalletManager
+
+### Decisions Made (per instructions)
+- Wallet scope: **PER SESSION** (each Matrix account has its own wallet)
+- Biometric change: **INVALIDATE** key + require wallet re-import/creation
+- Network: **TESTNET** (preprod) - single config constant for easy mainnet swap
+
+### Not Verified (No Android SDK in build environment)
+- ⚠️ Compilation with `./gradlew :features:wallet:impl:assemble`
+- ⚠️ Unit tests with `./gradlew :features:wallet:impl:test`
+- ⚠️ ktlint compliance
+- ⚠️ Actual Android Keystore behavior (requires device/emulator)
+- ⚠️ Biometric prompt integration (requires Activity context)
+
+### Security Notes
+1. **Mnemonic never stored in plaintext** - Always encrypted with Keystore key
+2. **Key material cleared after use** - `ByteArray.fill(0)` called where possible
+3. **Per-session isolation** - Different Matrix accounts cannot access each other's wallets
+4. **Biometric invalidation** - If user adds/removes fingerprints, wallet key becomes invalid
+5. **No screenshots** - UI must apply FLAG_SECURE when showing seed phrase

+## Task 3: Koios Client ✅ COMPLETE
+
+### Completed
+- ✅ **CardanoClient.kt** interface in `api/` module:
+  - `getBalance(address: String): Result<Long>` — balance in lovelace
+  - `getUtxos(address: String): Result<List<Utxo>>` — unspent outputs
+  - `submitTx(signedTxCbor: String): Result<String>` — returns tx hash
+  - `getTxStatus(txHash: String): Result<TxStatus>` — PENDING/CONFIRMED/FAILED
+
+- ✅ **Data models** in `api/`:
+  - `Utxo.kt` — txHash, outputIndex, amount, address
+  - `TxStatus.kt` — enum PENDING/CONFIRMED/FAILED
+  - `CardanoException.kt` — typed exceptions (NetworkException, RateLimitException, InvalidAddressException, TransactionNotFoundException, SubmissionFailedException, InsufficientFundsException, ApiException)
+
+- ✅ **KoiosCardanoClient.kt** implementation:
+  - Uses `BackendFactory.getKoiosBackendService()` from cardano-client-lib
+  - Testnet URL: `https://preprod.koios.rest/api/v1` (via CardanoNetworkConfig)
+  - Mainnet URL: `https://api.koios.rest/api/v1` (via CardanoNetworkConfig)
+  - 3 retries with exponential backoff (1s → 2s → 4s, max 10s)
+  - Basic rate limiting (100ms min between requests for Koios 100 req/10s limit)
+  - DI: `@ContributesBinding(SessionScope::class)`
+  - Error parsing: 429 → RateLimitException, 5xx → NetworkException, etc.
+
+- ✅ **FakeCardanoClient.kt** for testing:
+  - Configurable balances, UTxOs, transaction statuses
+  - Error simulation (network errors, rate limits, submit failures)
+  - Transaction lifecycle simulation (pending → confirmed → failed)
+  - Call counters for test verification
+  - Helper: `setupWallet(address, balance)` creates realistic UTxO set
+
+- ✅ **KoiosCardanoClientTest.kt** — 15+ unit tests:
+  - getBalance success, unknown address, network error, rate limit
+  - getUtxos success, empty result
+  - submitTx success, failure
+  - getTxStatus pending, confirmed, failed
+  - reset/state management
+
+- ✅ **CardanoWalletManager updated** to use CardanoClient:
+  - `refreshBalance()` now fetches real balance via Koios
+  - Updates WalletState with lovelace + formatted ADA string
+
+### Design Notes
+- **No API key required** — Koios public API is free
+- **Network config centralized** — Change `CardanoNetworkConfig.NETWORK` to swap testnet/mainnet
+- **Hex CBOR for submitTx** — Accepts hex-encoded signed transaction bytes
+- **UTxO pagination** — Limited to first 100 UTxOs (sufficient for typical wallets)
+
+### Potential Issues
+- ⚠️ `getTxStatus` returns PENDING for unknown hashes (could be never-submitted or truly pending)
+- ⚠️ Koios rate limit (100 req/10s) may need adjustment for heavy usage patterns
+- ⚠️ No getProtocolParameters yet (needed for Task 4 fee calculation)
+
+---
+
+## Task 4-6: See PHASE1-PLAN.md
+
+---
+
+## Task 7: Timeline Payment Card ✅ COMPLETE
+
+### Completed
+- ✅ **PaymentCardStatus.kt** — Enum for PENDING/CONFIRMED/FAILED states
+- ✅ **TimelineItemPaymentContent.kt** — Data class implementing TimelineItemEventContent
+  - amountLovelace, addresses, txHash, status, network, isSentByMe
+  - Computed properties: amountAda, isTestnet, truncatedTxHash, explorerUrl
+  - Companion formatAda() helper
+- ✅ **TimelineItemPaymentView.kt** — Compose UI for payment card
+  - Cardano icon (₳ symbol)
+  - Amount in ADA (formatted from lovelace)
+  - Status chip with spinner (pending), checkmark (confirmed), X (failed)
+  - Testnet badge when applicable
+  - Truncated tx hash (tappable → CardanoScan)
+  - View on explorer link for confirmed transactions
+  - @PreviewsDayNight with multiple preview states
+- ✅ **TimelineItemPaymentContentTest.kt** — Unit tests for content model
+- ✅ **Integration with TimelineItemEventContentView.kt**
+
+### Design Notes
+- Payment cards use different colors for sent (primary) vs received (surface)
+- Explorer URLs: preprod.cardanoscan.io for testnet, cardanoscan.io for mainnet
+- Tx hash truncated to first 8 + last 8 chars for display
+
+---
+
+## Task 8: Raw Event Handling ✅ COMPLETE (UPGRADED)
+
+### ✅ RESOLVED: SDK Raw Event API
+**Previous blocker:** Matrix Rust SDK did not expose raw event sending or raw JSON access.
+
+**Resolution:** The SDK (version 26.03.24) now provides:
+- `Timeline.sendRaw(eventType: String, content: String)` — Sends custom event types
+- `MsgLikeKind.Other` with `eventType` field — Receives custom events
+- `TimelineItemDebugInfo.originalJson` — Access to raw event JSON via debug info provider
+
+**Implementation updated to use proper raw events instead of text markers.**
+
+### Completed
+- ✅ **PaymentEventSender.kt** — Interface for sending payment events
+- ✅ **DefaultPaymentEventSender.kt** — Implementation using raw events
+  - Uses `timeline.sendRaw(eventType, content)` to send custom events
+  - Event type: `co.sulkta.payment.request` (reverse-domain format)
+  - Status updates: `co.sulkta.payment.status`
+  - No text marker hack — proper Matrix custom events
+- ✅ **TimelineItemContentPaymentFactory.kt** — Parser for payment events
+  - `isPaymentEventType(eventType)` — Checks for payment event type
+  - `isStatusUpdateEventType(eventType)` — Checks for status update type
+  - `createFromRaw(json, isSentByMe)` — Parses raw JSON from custom events
+  - Supports both camelCase and snake_case field names
+  - Graceful error handling — returns null on malformed JSON
+- ✅ **TimelineEventContentMapper.kt** — Maps `MsgLikeKind.Other` to `CustomEventContent`
+- ✅ **TimelineItemContentFactory.kt** — Handles `CustomEventContent` for payments
+  - Gets raw JSON via `timelineItemDebugInfoProvider().originalJson`
+  - Delegates to paymentFactory for payment event types
+- ✅ **CustomEventContent.kt** — New EventContent type for custom events
+- ✅ **Timeline.sendRaw()** — Added to Timeline interface and RustTimeline implementation
+- ✅ **FakePaymentEventSender.kt** — Test fake
+- ✅ **TimelineItemContentPaymentFactoryTest.kt** — Updated unit tests
+
+### m.replace Status Updates
+**Decision:** Status updates are sent as separate events of type `co.sulkta.payment.status`.
+
+**Future improvement:** When SDK exposes event relations, refactor to use m.replace for cleaner status update thread.
+
+### Benefits of Raw Event Approach
+- ✅ Proper Matrix protocol compliance (custom event types, not hacked text)
+- ✅ Non-wallet clients see "Unknown event" instead of JSON-in-text
+- ✅ Clean separation of payment events from regular messages
+- ✅ Events won't be indexed by message search
+- ✅ No message length limits concern
+
+---
+
+## Known Issues
+
+### Issue 1: Biometric Prompt Activity Context
+The `CardanoKeyStorageImpl` uses `setUserAuthenticationRequired(true)` which will cause `UserNotAuthenticatedException` when accessing the key. The biometric prompt UI must be triggered from an Activity/Fragment context before calling `getMnemonic()`, `getSpendingKey()`, etc.
+
+**Solution:** Task 6 (Payment Flow UI) must call BiometricPrompt before invoking storage operations.
+
+### Issue 2: KeyPermanentlyInvalidatedException
+If user changes biometric enrollment, the Keystore key is invalidated. Current behavior: throws exception, user must delete and recreate wallet.
+
+**Enhancement (future):** Show user-friendly message explaining why wallet became invalid and offer to re-import.

+# Phase 1 Status — COMPLETE ✅
+
+## Verification Date
+2026-03-28
+
+## What Was Verified
+- APK: `app-gplay-x86_64-debug.apk` built from `phase1-dev` branch
+- Installed on Android emulator `budtmo/docker-android:emulator_14.0` (emulator-5554)
+- Signed in as `@testbot-elementx:sulkta.com` via OIDC (MAS at mas.sulkta.com)
+- Opened DM room with `@cobb:sulkta.com`
+- Typed `/pay` in message composer
+
+## Result
+✅ Slash command autocomplete appeared showing:
+  - Command: `/pay`
+  - Description: "Send ADA to someone"
+
+## Phase 1 Bar (Option A) — All Conditions Met
+- [x] App launches without crash
+- [x] `/pay` appears in slash command autocomplete
+- [x] Payment screens navigable (wired in DI graph)
+- [x] No live testnet transaction required
+
+## Build Info
+- Gradle task: `:app:assembleGplayDebug`
+- Branch: `phase1-dev`
+- Final commit: `ad89eddfea`
+- Build image: `mingc/android-build-box:latest` (Java 21)
+
+## Key Fixes Applied
+1. Metro DI scope mismatch: CardanoWalletManager removed CardanoClient dep (AppScope vs SessionScope)
+2. WalletState constructor: all required fields populated
+3. Packaging conflict: moshi-kotlin-codegen/lombok META-INF pickFirst
+4. Build flavor: assembleGplayDebug (not fdroid, not plain assembleDebug)

+# Repo topology + upstream sync procedure
+
+This repo is a fork of [`element-hq/element-x-android`](https://github.com/element-hq/element-x-android)
+with a native Cardano wallet module added. The history is structured so that
+staying current with upstream — and one day proposing our additions back —
+stays possible.
+
+## Branches
+
+| Branch | Role |
+|--------|------|
+| `main` | Tracks the upstream commit we are currently based on. Fast-forwarded to `upstream/develop` when we deliberately pull in changes. Nothing coop-specific lives here. |
+| `wallet` | `main` + all our wallet work. This is what we build APKs from. Linear history on top of `main`; rebased whenever `main` moves. |
+| `archive/project-docs` | Frozen snapshot of the planning docs and screenshots that lived on the original orphan `main` branch. Not part of the active graph. |
+
+When we ever want a clean "everything we'd propose upstream" branch, we cherry-pick
+the wallet commits off `wallet` onto a fresh branch rooted at `main`. Because every
+current commit on `wallet` is wallet-module work, that split is simple.
+
+## Remotes
+
+`origin` → this Gitea repo (LAN, via the Rackham SSH tunnel when working remotely).
+
+Add upstream on any local clone:
+
+```bash
+git remote add upstream https://github.com/element-hq/element-x-android.git
+git fetch upstream
+```
+
+## Sync with upstream
+
+When you want to pick up the latest from `element-hq/element-x-android`:
+
+```bash
+# 1. Get the latest from upstream
+git fetch upstream
+
+# 2. Fast-forward main to upstream/develop
+git checkout main
+git merge --ff-only upstream/develop
+git push origin main
+
+# 3. Rebase wallet onto the new main
+git checkout wallet
+git rebase main
+# → resolve conflicts, one commit at a time
+# → conflict surface is small but real: our integration touches
+#   libraries/matrix/{api,impl}, libraries/textcomposer/impl,
+#   libraries/eventformatter/impl, libraries/mediaviewer/impl
+
+# 4. Build + test the APK before force-pushing
+./gradlew :app:assembleFdroidDebug   # or mainnet variant
+
+# 5. Push the rebased wallet branch (force-with-lease, not plain force)
+git push --force-with-lease origin wallet
+```
+
+If the rebase gets ugly, abort and try merging instead:
+
+```bash
+git rebase --abort
+git merge upstream/develop
+# resolves in one shot, one merge commit, less clean history
+```
+
+## Why not a Gitea mirror?
+
+Gitea only lets you configure a pull-mirror at repo-creation time, and mirroring
+a whole repo also means we can't commit to it. We want to keep our own commits,
+so upstream stays as a git remote you fetch from manually.
+
+## License
+
+Upstream is **AGPL-3.0**. Every binary we hand out must be accompanied by the
+corresponding source under the same license. Keeping this Gitea repo accessible
+to recipients of the APK satisfies that. Don't ship binaries without also making
+the source reachable.
