+### Items to complete
+
+All items below are to be completed by the owner of the given release.
+
+- [ ] Create release branch with major and minor only ( e.g. release/v0.X ) if it doesn't exist.
+- [ ] Assign release candidate tag to the release branch HEAD (e.g. `v0.X.0-beta-rc.0`, `v0.X.0-beta-rc.1`, ... `v0.X.0-beta-rc.N`).
+- [ ] Generate and edit release notes in CHANGELOG.md.
+
+- [ ] **Waku test and fleets validation**
+  - [ ] Ensure all the unit tests (specifically js-waku tests) are green against the release candidate.
+  - [ ] Deploy the release candidate to `waku.test` only through [deploy-waku-test job](https://ci.infra.status.im/job/nim-waku/job/deploy-waku-test/) and wait for it to finish (Jenkins access required; ask the infra team if you don't have it).
+    - After completion, disable [deployment job](https://ci.infra.status.im/job/nim-waku/) so that its version is not updated on every merge to master.
+    - Verify the deployed version at https://fleets.waku.org/.
+    - Confirm the container image exists on [Harbor](https://harbor.status.im/harbor/projects/9/repositories/nwaku/artifacts-tab).
+  - [ ] Analyze Kibana logs from the previous month (since the last release was deployed) for possible crashes or errors in `waku.test`.
+      - Most relevant logs are `(fleet: "waku.test" AND message: "SIGSEGV")`.
+  - [ ] Enable again the `waku.test` fleet to resume auto-deployment of the latest `master` commit.
+
+- [ ] **Proceed with release**
+
+  - [ ] Assign a final release tag (`v0.X.0-beta`) to the same commit that contains the validated release-candidate tag (e.g. `v0.X.0-beta-rc.N`) and submit a PR from the release branch to `master`.
+  - [ ] Update [nwaku-compose](https://github.com/logos-messaging/nwaku-compose) and [waku-simulator](https://github.com/logos-messaging/waku-simulator) according to the new release.
+  - [ ] Bump nwaku dependency in [waku-rust-bindings](https://github.com/logos-messaging/waku-rust-bindings) and make sure all examples and tests work.
+  - [ ] Bump nwaku dependency in [waku-go-bindings](https://github.com/logos-messaging/waku-go-bindings) and make sure all tests work.
+  - [ ] Create GitHub release (https://github.com/logos-messaging/nwaku/releases).
+  - [ ] Submit a PR to merge the release branch back to `master`. Make sure you use the option "Merge pull request (Create a merge commit)" to perform the merge. Ping repo admin if this option is not available.
+
+- [ ] **Promote release to fleets**
+  - [ ] Ask the PM lead to announce the release.
+  - [ ] Update infra config with any deprecated arguments or changed options.
+  - [ ] Update waku.sandbox with [this deployment job](https://ci.infra.status.im/job/nim-waku/job/deploy-waku-sandbox/).

+# AGENTS.md - AI Coding Context
+
+This file provides essential context for LLMs assisting with Logos Messaging development.
+
+## Project Identity
+
+Logos Messaging is designed as a shared public network for generalized messaging, not application-specific infrastructure.
+
+This project is a Nim implementation of a libp2p protocol suite for private, censorship-resistant P2P messaging. It targets resource-restricted devices and privacy-preserving communication.
+
+Logos Messaging was formerly known as Waku. Waku-related terminology remains within the codebase for historical reasons.
+
+### Design Philosophy
+
+Key architectural decisions:
+
+Resource-restricted first: Protocols differentiate between full nodes (relay) and light clients (filter, lightpush, store). Light clients can participate without maintaining full message history or relay capabilities. This explains the client/server split in protocol implementations.
+
+Privacy through unlinkability: RLN (Rate Limiting Nullifier) provides DoS protection while preserving sender anonymity. Messages are routed through pubsub topics with automatic sharding across 8 shards. Code prioritizes metadata privacy alongside content encryption.
+
+Scalability via sharding: The network uses automatic content-topic-based sharding to distribute traffic. This is why you'll see sharding logic throughout the codebase and why pubsub topic selection is protocol-level, not application-level.
+
+See [documentation](https://docs.waku.org/learn/) for architectural details.
+
+### Core Protocols
+- Relay: Pub/sub message routing using GossipSub
+- Store: Historical message retrieval and persistence
+- Filter: Lightweight message filtering for resource-restricted clients
+- Lightpush: Lightweight message publishing for clients
+- Peer Exchange: Peer discovery mechanism
+- RLN Relay: Rate limiting nullifier for spam protection
+- Metadata: Cluster and shard metadata exchange between peers
+- Mix: Mixnet protocol for enhanced privacy through onion routing
+- Rendezvous: Alternative peer discovery mechanism
+
+### Key Terminology
+- ENR (Ethereum Node Record): Node identity and capability advertisement
+- Multiaddr: libp2p addressing format (e.g., `/ip4/127.0.0.1/tcp/60000/p2p/16Uiu2...`)
+- PubsubTopic: Gossipsub topic for message routing (e.g., `/waku/2/default-waku/proto`)
+- ContentTopic: Application-level message categorization (e.g., `/my-app/1/chat/proto`)
+- Sharding: Partitioning network traffic across topics (static or auto-sharding)
+- RLN (Rate Limiting Nullifier): Zero-knowledge proof system for spam prevention
+
+### Specifications
+All specs are at [rfc.vac.dev/waku](https://rfc.vac.dev/waku). RFCs use `WAKU2-XXX` format (not legacy `WAKU-XXX`).
+
+## Architecture
+
+### Protocol Module Pattern
+Each protocol typically follows this structure:
+```
+waku_<protocol>/
+├── protocol.nim       # Main protocol type and handler logic
+├── client.nim         # Client-side API
+├── rpc.nim           # RPC message types
+├── rpc_codec.nim     # Protobuf encoding/decoding
+├── common.nim        # Shared types and constants
+└── protocol_metrics.nim  # Prometheus metrics
+```
+
+### WakuNode Architecture
+- WakuNode (`waku/node/waku_node.nim`) is the central orchestrator
+- Protocols are "mounted" onto the node's switch (libp2p component)
+- PeerManager handles peer selection and connection management
+- Switch provides libp2p transport, security, and multiplexing
+
+Example protocol type definition:
+```nim
+type WakuFilter* = ref object of LPProtocol
+  subscriptions*: FilterSubscriptions
+  peerManager: PeerManager
+  messageCache: TimedCache[string]
+```
+
+## Development Essentials
+
+### Build Requirements
+- Nim 2.x (check `waku.nimble` for minimum version)
+- Rust toolchain (required for RLN dependencies)
+- Build system: Make with nimbus-build-system
+
+### Build System
+The project uses Makefile with nimbus-build-system (Status's Nim build framework):
+```bash
+# Initial build (updates submodules)
+make wakunode2
+
+# After git pull, update submodules
+make update
+
+# Build with custom flags
+make wakunode2 NIMFLAGS="-d:chronicles_log_level=DEBUG"
+```
+
+Note: The build system uses `--mm:refc` memory management (automatically enforced). Only relevant if compiling outside the standard build system.
+
+### Common Make Targets
+```bash
+make wakunode2          # Build main node binary
+make test               # Run all tests
+make testcommon         # Run common tests only
+make libwakuStatic      # Build static C library
+make chat2              # Build chat example
+make install-nph        # Install git hook for auto-formatting
+```
+
+### Testing
+```bash
+# Run all tests
+make test
+
+# Run specific test file
+make test tests/test_waku_enr.nim
+
+# Run specific test case from file
+make test tests/test_waku_enr.nim "check capabilities support"
+
+# Build and run test separately (for development iteration)
+make test tests/test_waku_enr.nim
+```
+
+Test structure uses `testutils/unittests`:
+```nim
+import testutils/unittests
+
+suite "Waku ENR - Capabilities":
+  test "check capabilities support":
+    ## Given
+    let bitfield: CapabilitiesBitfield = 0b0000_1101u8
+    
+    ## Then
+    check:
+      bitfield.supportsCapability(Capabilities.Relay)
+      not bitfield.supportsCapability(Capabilities.Store)
+```
+
+### Code Formatting
+Mandatory: All code must be formatted with `nph` (vendored in `vendor/nph`)
+```bash
+# Format specific file
+make nph/waku/waku_core.nim
+
+# Install git pre-commit hook (auto-formats on commit)
+make install-nph
+```
+The nph formatter handles all formatting details automatically, especially with the pre-commit hook installed. Focus on semantic correctness.
+
+### Logging
+Uses `chronicles` library with compile-time configuration:
+```nim
+import chronicles
+
+logScope:
+  topics = "waku lightpush"
+
+info "handling request", peerId = peerId, topic = pubsubTopic
+error "request failed", error = msg
+```
+
+Compile with log level:
+```bash
+nim c -d:chronicles_log_level=TRACE myfile.nim
+```
+
+
+## Code Conventions
+
+Common pitfalls:
+- Always handle Result types explicitly
+- Avoid global mutable state: Pass state through parameters
+- Keep functions focused: Under 50 lines when possible
+- Prefer compile-time checks (`static assert`) over runtime checks
+
+### Naming
+- Files/Directories: `snake_case` (e.g., `waku_lightpush`, `peer_manager`)
+- Procedures: `camelCase` (e.g., `handleRequest`, `pushMessage`)
+- Types: `PascalCase` (e.g., `WakuFilter`, `PubsubTopic`)
+- Constants: `PascalCase` (e.g., `MaxContentTopicsPerRequest`)
+- Constructors: `func init(T: type Xxx, params): T`
+- For ref types: `func new(T: type Xxx, params): ref T`
+- Exceptions: `XxxError` for CatchableError, `XxxDefect` for Defect
+- ref object types: `XxxRef` suffix
+
+### Imports Organization
+Group imports: stdlib, external libs, internal modules:
+```nim
+import
+  std/[options, sequtils],      # stdlib
+  results, chronicles, chronos,  # external
+  libp2p/peerid
+import
+  ../node/peer_manager,          # internal (separate import block)
+  ../waku_core,
+  ./common
+```
+
+### Async Programming
+Uses chronos, not stdlib `asyncdispatch`:
+```nim
+proc handleRequest(
+    wl: WakuLightPush, peerId: PeerId
+): Future[WakuLightPushResult] {.async.} =
+  let res = await wl.pushHandler(peerId, pubsubTopic, message)
+  return res
+```
+
+### Error Handling
+The project uses both Result types and exceptions:
+
+Result types from nim-results are used for protocol and API-level errors:
+```nim
+proc subscribe(
+    wf: WakuFilter, peerId: PeerID
+): Future[FilterSubscribeResult] {.async.} =
+  if contentTopics.len > MaxContentTopicsPerRequest:
+    return err(FilterSubscribeError.badRequest("exceeds maximum"))
+  
+  # Handle Result with isOkOr
+  (await wf.subscriptions.addSubscription(peerId, criteria)).isOkOr:
+    return err(FilterSubscribeError.serviceUnavailable(error))
+  
+  ok()
+```
+
+Exceptions still used for:
+- chronos async failures (CancelledError, etc.)
+- Database/system errors
+- Library interop
+
+Most files start with `{.push raises: [].}` to disable exception tracking, then use try/catch blocks where needed.
+
+### Pragma Usage
+```nim
+{.push raises: [].}  # Disable default exception tracking (at file top)
+
+proc myProc(): Result[T, E] {.async.} =  # Async proc
+```
+
+### Protocol Inheritance
+Protocols inherit from libp2p's `LPProtocol`:
+```nim
+type WakuLightPush* = ref object of LPProtocol
+  rng*: ref rand.HmacDrbgContext
+  peerManager*: PeerManager
+  pushHandler*: PushMessageHandler
+```
+
+### Type Visibility
+- Public exports use `*` suffix: `type WakuFilter* = ...`
+- Fields without `*` are module-private
+
+## Style Guide Essentials
+
+This section summarizes key Nim style guidelines relevant to this project. Full guide: https://status-im.github.io/nim-style-guide/
+
+### Language Features
+
+Import and Export
+- Use explicit import paths with std/ prefix for stdlib
+- Group imports: stdlib, external, internal (separate blocks)
+- Export modules whose types appear in public API
+- Avoid include
+
+Macros and Templates
+- Avoid macros and templates - prefer simple constructs
+- Avoid generating public API with macros
+- Put logic in templates, use macros only for glue code
+
+Object Construction
+- Prefer Type(field: value) syntax
+- Use Type.init(params) convention for constructors
+- Default zero-initialization should be valid state
+- Avoid using result variable for construction
+
+ref object Types
+- Avoid ref object unless needed for:
+  - Resource handles requiring reference semantics
+  - Shared ownership
+  - Reference-based data structures (trees, lists)
+  - Stable pointer for FFI
+- Use explicit ref MyType where possible
+- Name ref object types with Ref suffix: XxxRef
+
+Memory Management
+- Prefer stack-based and statically sized types in core code
+- Use heap allocation in glue layers
+- Avoid alloca
+- For FFI: use create/dealloc or createShared/deallocShared
+
+Variable Usage
+- Use most restrictive of const, let, var (prefer const over let over var)
+- Prefer expressions for initialization over var then assignment
+- Avoid result variable - use explicit return or expression-based returns
+
+Functions
+- Prefer func over proc
+- Avoid public (*) symbols not part of intended API
+- Prefer openArray over seq for function parameters
+
+Methods (runtime polymorphism)
+- Avoid method keyword for dynamic dispatch
+- Prefer manual vtable with proc closures for polymorphism
+- Methods lack support for generics
+
+Miscellaneous
+- Annotate callback proc types with {.raises: [], gcsafe.}
+- Avoid explicit {.inline.} pragma
+- Avoid converters
+- Avoid finalizers
+
+Type Guidelines
+
+Binary Data
+- Use byte for binary data
+- Use seq[byte] for dynamic arrays
+- Convert string to seq[byte] early if stdlib returns binary as string
+
+Integers
+- Prefer signed (int, int64) for counting, lengths, indexing
+- Use unsigned with explicit size (uint8, uint64) for binary data, bit ops
+- Avoid Natural
+- Check ranges before converting to int
+- Avoid casting pointers to int
+- Avoid range types
+
+Strings
+- Use string for text
+- Use seq[byte] for binary data instead of string
+
+### Error Handling
+
+Philosophy
+- Prefer Result, Opt for explicit error handling
+- Use Exceptions only for legacy code compatibility
+
+Result Types
+- Use Result[T, E] for operations that can fail
+- Use cstring for simple error messages: Result[T, cstring]
+- Use enum for errors needing differentiation: Result[T, SomeErrorEnum]
+- Use Opt[T] for simple optional values
+- Annotate all modules: {.push raises: [].} at top
+
+Exceptions (when unavoidable)
+- Inherit from CatchableError, name XxxError
+- Use Defect for panics/logic errors, name XxxDefect
+- Annotate functions explicitly: {.raises: [SpecificError].}
+- Catch specific error types, avoid catching CatchableError
+- Use expression-based try blocks
+- Isolate legacy exception code with try/except, convert to Result
+
+Common Defect Sources
+- Overflow in signed arithmetic
+- Array/seq indexing with []
+- Implicit range type conversions
+
+Status Codes
+- Avoid status code pattern
+- Use Result instead
+
+### Library Usage
+
+Standard Library
+- Use judiciously, prefer focused packages
+- Prefer these replacements:
+  - async: chronos
+  - bitops: stew/bitops2
+  - endians: stew/endians2
+  - exceptions: results
+  - io: stew/io2
+
+Results Library
+- Use cstring errors for diagnostics without differentiation
+- Use enum errors when caller needs to act on specific errors
+- Use complex types when additional error context needed
+- Use isOkOr pattern for chaining
+
+Wrappers (C/FFI)
+- Prefer native Nim when available
+- For C libraries: use {.compile.} to build from source
+- Create xxx_abi.nim for raw ABI wrapper
+- Avoid C++ libraries
+
+Miscellaneous
+- Print hex output in lowercase, accept both cases
+
+### Common Pitfalls
+
+- Defects lack tracking by {.raises.}
+- nil ref causes runtime crashes
+- result variable disables branch checking
+- Exception hierarchy unclear between Nim versions
+- Range types have compiler bugs
+- Finalizers infect all instances of type
+
+## Common Workflows
+
+### Adding a New Protocol
+1. Create directory: `waku/waku_myprotocol/`
+2. Define core files:
+   - `rpc.nim` - Message types
+   - `rpc_codec.nim` - Protobuf encoding
+   - `protocol.nim` - Protocol handler
+   - `client.nim` - Client API
+   - `common.nim` - Shared types
+3. Define protocol type in `protocol.nim`:
+   ```nim
+   type WakuMyProtocol* = ref object of LPProtocol
+     peerManager: PeerManager
+     # ... fields
+   ```
+4. Implement request handler
+5. Mount in WakuNode (`waku/node/waku_node.nim`)
+6. Add tests in `tests/waku_myprotocol/`
+7. Export module via `waku/waku_myprotocol.nim`
+
+### Adding a REST API Endpoint
+1. Define handler in `waku/rest_api/endpoint/myprotocol/`
+2. Implement endpoint following pattern:
+   ```nim
+   proc installMyProtocolApiHandlers*(
+       router: var RestRouter, node: WakuNode
+   ) =
+     router.api(MethodGet, "/waku/v2/myprotocol/endpoint") do () -> RestApiResponse:
+       # Implementation
+       return RestApiResponse.jsonResponse(data, status = Http200)
+   ```
+3. Register in `waku/rest_api/handlers.nim`
+
+### Adding Database Migration
+For message_store (SQLite):
+1. Create `migrations/message_store/NNNNN_description.up.sql`
+2. Create corresponding `.down.sql` for rollback
+3. Increment version number sequentially
+4. Test migration locally before committing
+
+For PostgreSQL: add in `migrations/message_store_postgres/`
+
+### Running Single Test During Development
+```bash
+# Build test binary
+make test tests/waku_filter_v2/test_waku_client.nim
+
+# Binary location
+./build/tests/waku_filter_v2/test_waku_client.nim.bin
+
+# Or combine
+make test tests/waku_filter_v2/test_waku_client.nim "specific test name"
+```
+
+### Debugging with Chronicles
+Set log level and filter topics:
+```bash
+nim c -r \
+  -d:chronicles_log_level=TRACE \
+  -d:chronicles_disabled_topics="eth,dnsdisc" \
+  tests/mytest.nim
+```
+
+## Key Constraints
+
+### Vendor Directory
+- Never edit files directly in vendor - it is auto-generated from git submodules
+- Always run `make update` after pulling changes
+- Managed by `nimbus-build-system`
+
+### Chronicles Performance
+- Log levels are configured at compile time for performance
+- Runtime filtering is available but should be used sparingly: `-d:chronicles_runtime_filtering=on`
+- Default sinks are optimized for production
+
+### Memory Management
+- Uses `refc` (reference counting with cycle collection)
+- Automatically enforced by the build system (hardcoded in `waku.nimble`)
+- Do not override unless absolutely necessary, as it breaks compatibility
+
+### RLN Dependencies
+- RLN code requires a Rust toolchain, which explains Rust imports in some modules
+- Pre-built `librln` libraries are checked into the repository
+
+## Quick Reference
+
+Language: Nim 2.x | License: MIT or Apache 2.0

-# Nwaku
+# Logos Messaging Nim
 
 ## Introduction
 
-The nwaku repository implements Waku, and provides tools related to it.
+The logos-messaging-nim, a.k.a. lmn or nwaku, repository implements a set of libp2p protocols aimed to bring
+private communications.
 
-- A Nim implementation of the [Waku (v2) protocol](https://specs.vac.dev/specs/waku/v2/waku-v2.html).
-- CLI application `wakunode2` that allows you to run a Waku node.
-- Examples of Waku usage.
+- Nim implementation of [these specs](https://github.com/vacp2p/rfc-index/tree/main/waku).
+- C library that exposes the implemented protocols.
+- CLI application that allows you to run an lmn node.
+- Examples.
 - Various tests of above.
 
 For more details see the [source code](waku/README.md)
 
 ## How to Build & Run ( Linux, MacOS & WSL )
 
-These instructions are generic. For more detailed instructions, see the Waku source code above.

 ## How to do releases
 
-### Before release
+### Prerequisites
+
+- All issues under the corresponding release [milestone](https://github.com/waku-org/nwaku/milestones) have been closed or, after consultation, deferred to the next release.
+- All submodules are up to date.
+  > Updating submodules requires a PR (and very often several "fixes" to maintain compatibility with the changes in submodules). That PR process must be done and merged a couple of days before the release.

-- [ ] All issues under the corresponding release [milestone](https://github.com/waku-org/nwaku/milestones) has been closed or, after consultation, deferred to a next release.
-- [ ] All submodules are up to date.
-  > **IMPORTANT:** Updating submodules requires a PR (and very often several "fixes" to maintain compatibility with the changes in submodules). That PR process must be done and merged a couple of days before the release.
   > In case the submodules update has a low effort and/or risk for the release, follow the ["Update submodules"](./git-submodules.md) instructions.
-  > If the effort or risk is too high, consider postponing the submodules upgrade for the subsequent release or delaying the current release until the submodules updates are included in the release candidate.
-- [ ] The [js-waku CI tests](https://github.com/waku-org/js-waku/actions/workflows/ci.yml) pass against the release candidate (i.e. nwaku latest `master`).
-  > **NOTE:** This serves as a basic regression test against typical clients of nwaku.
-  > The specific job that needs to pass is named `node_with_nwaku_master`.

+6. **Validation of release candidate**
+
+   6a. **Automated testing**
+     - Ensure all the unit tests (specifically js-waku tests) are green against the release candidate.
+     - Ask Vac-QA and Vac-DST to run their available tests against the release candidate; share all release candidates with both teams.
+
+     > We need an additional report like [this](https://www.notion.so/DST-Reports-1228f96fb65c80729cd1d98a7496fe6f) specifically from the DST team.
+
+   6b. **Waku fleet testing**
+      - Start job on `waku.sandbox` and `waku.test` [Deployment job](https://ci.infra.status.im/job/nim-waku/), wait for completion of the job. If it fails, then debug it.
+      - After completion, disable [deployment job](https://ci.infra.status.im/job/nim-waku/) so that its version is not updated on every merge to `master`.
+      - Verify at https://fleets.waku.org/ that the fleet is locked to the release candidate version.
+      - Check if the image is created at [Harbor](https://harbor.status.im/harbor/projects/9/repositories/nwaku/artifacts-tab).
+      - Search _Kibana_ logs from the previous month (since the last release was deployed) for possible crashes or errors in `waku.test` and `waku.sandbox`.
+        - Most relevant logs are `(fleet: "waku.test" AND message: "SIGSEGV")` OR `(fleet: "waku.sandbox" AND message: "SIGSEGV")`.
+      - Enable the `waku.test` fleet again to resume auto-deployment of the latest `master` commit.
+
+   6c. **Status fleet testing**
+     - Deploy release candidate to `status.staging`
+     - Perform [sanity check](https://www.notion.so/How-to-test-Nwaku-on-Status-12c6e4b9bf06420ca868bd199129b425) and log results as comments in this issue.
+       - Connect 2 instances to `status.staging` fleet, one in relay mode, the other one in light client.
+       - 1:1 Chats with each other
+       - Send and receive messages in a community
+       - Close one instance, send messages with second instance, reopen first instance and confirm messages sent while offline are retrieved from store
+     - Perform checks based on _end-user impact_.
+     - Inform other (Waku and Status) CCs to point their instances to `status.staging` for a few days. Ping Status colleagues from their Discord server or [Status community](https://status.app) (not a blocking point).
+     - Ask Status-QA to perform sanity checks (as described above) and checks based on _end user impact_; specify the version being tested.
+     - Ask Status-QA or infra to run the automated Status e2e tests against `status.staging`.
+     - Get other CCs' sign-off: they should comment on this PR, e.g., "Used the app for a week, no problem." If problems are reported, resolve them and create a new RC.
+     - **Get Status-QA sign-off**, ensuring that the `status.test` update will not disturb ongoing activities.
