Purpose

EastMesh layer on top of upstream MeshCore.

Default: preserve upstream behavior.
Only modify code for clearly scoped EastMesh features:

• *_repeater_mqtt
• *_companion_radio_wifi
• MQTT uplink/broker
• repeater web panel
• docs, releases, automation

Principles

• Minimal, targeted changes
• Prefer additive over modifying upstream code
• Avoid unrelated refactors
• Maintain parity with upstream behavior

Guardrails

Upstream

• Do not modify unrelated MeshCore logic
• Do not change CLI semantics unless explicitly required
• Do not introduce breaking changes to existing targets

Docs (update in same PR when practical)

Change	File
CLI	eastmesh-docs/custom-cli.md
Web panel UI/behavior	eastmesh-docs/web-panel.md
Releases	release-notes.yml
Flashing guidance	eastmesh-docs/releases.md

Web Panel Gate

If editing examples/simple_repeater/MyMesh.cpp, also update eastmesh-docs/custom-cli.md.

Tooling

• Use uv + PlatformIO via uv run
• Do not assume global pio

Build Policy

Builds are expensive. Avoid unless necessary.

Do NOT build for:

• docs / HTML / CSS only

Prefer:

• user-run local builds
• reasoning over execution

Build only if:

• high-risk change
• firmware behavior must be verified

Commands

uv sync
uv run pio run -e <env>
uv run pio device monitor --port <port> --baud 115200
uv run --group docs zensical serve
uv run --group docs zensical build

Do not assume pio is installed globally.

Common Commands

List build targets:

bash build.sh list

Build a single target:

uv run pio run -e heltec_v4_repeater_mqtt
uv run pio run -e T_Beam_S3_Supreme_SX1262_repeater_mqtt
uv run pio run -e heltec_v4_companion_radio_wifi
uv run pio run -e T_Beam_S3_Supreme_SX1262_companion_radio_wifi

Build with release-style metadata:

export FIRMWARE_VERSION=v1.14.1
export EASTMESH_VERSION=v1.0.1
bash build.sh build-firmware heltec_v4_repeater_mqtt
bash build.sh build-firmware T_Beam_S3_Supreme_SX1262_repeater_mqtt

Flash a target:

uv run pio run -e heltec_v4_repeater_mqtt -t upload --upload-port /dev/tty.usbmodemXXXX
uv run pio run -e T_Beam_S3_Supreme_SX1262_repeater_mqtt -t upload --upload-port /dev/tty.usbmodemXXXX

Workflow Ownership

EastMesh workflows use the eastmesh-*.yml prefix in .github/workflows/.

Upstream MeshCore workflows may remain under their original filenames for merge hygiene. Do not adapt them for EastMesh behavior; keep them close to upstream and disable them in GitHub Actions for this repository.

Docs Sync Requirements

If you change any of the following, update docs in the same PR when practical:

• Web-panel commands:
  • update eastmesh-docs/custom-cli.md
• Web-panel user-facing behavior, sections, controls, or troubleshooting:
  • update eastmesh-docs/web-panel.md
• EastMesh CLI additions or changed semantics:
  • update eastmesh-docs/custom-cli.md
• Release/tag preparation:
  • update release-notes.yml
• Flashing/release asset guidance:
  • update eastmesh-docs/releases.md

Repeater MQTT Notes

*_repeater_mqtt builds may include the local HTTPS web panel on supported ESP32 targets.

Operational guidance already reflected in docs:

• use for initial setup and troubleshooting
• prefer set web off afterward for maximum heap headroom

Companion WiFi Notes

*_companion_radio_wifi targets support persisted Wi-Fi rescue commands via serial CLI Rescue.

Do not document companion rescue commands in repeater docs. Do not assume web-panel behavior applies.

Companion release/version rule:

• companion tags use the official upstream MeshCore release version only
• the current official MeshCore version is v1.14.1
• companion releases are only cut when meshcore-dev/MeshCore has made an official release
• do not invent separate EastMesh companion version numbers

Release Workflow

Current tag formats:

git tag companion-wifi-v1.2.3
git tag repeater-mqtt-eastmesh-v1.0.1

Rules:

• companion-wifi tags use the upstream MeshCore version directly
• repeater-mqtt tags use the EastMesh release version in the tag
• GitHub Actions variable OFFICIAL_MESHCORE_VERSION supplies the upstream base version for repeater MQTT release builds
• if the upstream MeshCore release version changes, update OFFICIAL_MESHCORE_VERSION in GitHub before cutting release tags

Typical release flow:

1. Update OFFICIAL_MESHCORE_VERSION if upstream changed.
2. Update release-notes.yml on develop.
3. Merge the release PR from develop to main.
4. Create the desired release tag or tags on the target commit on main.
5. Push the tags.

Upstream Sync Workflow

When asked to pull from upstream MeshCore:

• pull from meshcore-dev/MeshCore:dev
• start from local develop
• create a temporary integration branch off develop
• merge upstream dev into that temporary integration branch
• resolve conflicts in a way that preserves EastMesh-specific changes
• merge the finished integration branch back into develop

Do not merge upstream directly into main.

Scope Boundaries

Do NOT (unless asked):

• rename tracks
• change tag formats
• expand cli without updating docs
• change upstream CLI semantics
• introduce new versioning schemes

Commit Messages

Use concise, conventional prefixes:

• feat: new functionality
• fix: bug fixes
• docs: documentation changes
• chore: maintenance, tooling, non-functional
• refactor: code changes without behavior change

Keep messages short and scoped.

Decision Rule

If a change is not clearly EastMesh-specific, do not modify the code. When uncertain, prefer no change or request clarification.
