Espressif IDF Component Manager dependencies.lock commit lock file managed registry dependencies version resolution

💡 Result:

The dependencies.lock file is a critical component of the Espressif IDF Component Manager, designed to ensure reproducible builds by locking project dependencies to exact, verified versions [1]. Key functions and behavior of the dependencies.lock file include: 1. Version Resolution: The IDF Component Manager uses the PubGrub algorithm to resolve component dependencies defined in manifest files (e.g., idf_component.yml) into a set of specific, compatible versions [2][3]. 2. Reproducibility: Once resolved, these exact versions are recorded in the dependencies.lock file. This ensures that every developer and build environment uses the same component versions, preventing unexpected updates or inconsistencies [1]. 3. Automated Management: The file is generated automatically by the component manager when it runs (e.g., during idf.py reconfigure) [4]. Users should not manually edit it; it is updated only by the version solver [1][4]. 4. Triggers for Updates: The solver recalculates dependencies and updates the lock file if: - The dependencies.lock file is missing [2][3]. - The hash of the project manifests (idf_component.yml) has changed [2][3]. - The build target (e.g., ESP32 vs. ESP32-S3) specified in the lock file no longer matches the current target [2][3]. 5. Version Control Best Practices: For projects using ESP Component Registry or Git dependencies, it is recommended to check the dependencies.lock file into version control [1]. However, it should be excluded from version control if the project includes Kconfig Options or local paths, as these may contain environment-specific information that is not portable [1]. The component manager automatically downloads dependencies to a managed_components directory in the project root based on the resolved versions in the lock file [4]. If the lock file or the managed_components directory are accidentally modified or deleted, they can be restored by re-running the component manager via the build system (e.g., idf.py reconfigure) [4].

Citations:

Commit moonbase/dependencies.lock for the managed dependency.

moonbase/main/idf_component.yml declares the registry dependency joltwallet/littlefs (^1.16.0). Because .gitignore excludes the generated lock file, builds without a local lock can resolve different component versions. Remove the ignore entry and commit the generated lock file.

🎨 **Plug in, open a browser, see lights**: a live 3D preview of every effect, modifier, and layout, controllable from the same tab. The interface renders any module from its declared controls, so adding a module needs zero UI code.

🌗 **MoonBase, the second boot image (4 MB boards)**: instead of spending half a small flash on a second firmware copy, a ~750 KB maintenance image sits in the factory slot and installs updates into one large app slot, one click in the UI covers the whole reboot-install-reboot cycle, and a power cut mid-update lands back in MoonBase, never in a half-written app. See [architecture.md § MoonBase](docs/architecture.md#moonbase-the-second-boot-image-4-mb-boards).

⚡ **Flash from your browser in seconds**: the web installer picks your device, flashes the matching firmware, and hands WiFi credentials to the device over USB via Improv. No serial monitor, no recompile.

- **The [Improv Wi-Fi](https://github.com/improv-wifi) project**: the open Improv serial provisioning standard ([sdk-cpp](https://github.com/improv-wifi/sdk-cpp) / [sdk-js](https://github.com/improv-wifi/sdk-js)) that the projectMM web installer uses to provision a freshly-flashed device over USB.
- **[FastLED](https://github.com/FastLED/FastLED)**: the canonical LED-effects library whose conventions the LED-effect world shares. projectMM links no part of FastLED, but it carries forward FastLED's recognisable *names and models* for the color/animation primitives (`scale8`, `sin8`, the gradient-palette model (`CRGBPalette16` / `colorFromPalette`), the `beatsin8` / `inoise8` / `qadd8` family), so a contributor recognises them on sight. The implementations are projectMM's own, integer-only and hot-path-tuned for our render loop; FastLED is the prior art behind the convention, credited here and in each primitive's notes.
- **[FPP](https://github.com/FalconChristmas/fpp) (Falcon Player)**: the show player that drives LED panel receiver cards from a Raspberry Pi. Seeing an FPP rig feed a wall of HUB75 panels is what prompted [PanelCardDriver](docs/moonmodules/light/drivers.md#panelcard): if a Linux host can send those frames, so can a board that is already rendering them, which removes the host from the installation entirely. FPP is the inspiration, and the reference point for what good looks like here: it sustains 50 fps.
- **[Tasmota](https://github.com/arendst/Tasmota) and Mathieu Carbou's [MycilaSafeBoot](https://github.com/mathieucarbou/MycilaSafeBoot)**: the safeboot pattern behind [MoonBase](docs/architecture.md#moonbase-the-second-boot-image-4-mb-boards): replacing a small board's second OTA slot with a minimal boot image that installs into one large app slot. Tasmota proved the scheme at scale; MycilaSafeBoot distilled it to a standalone image and set the size bar. MoonBase is our from-scratch minimal take, written directly against ESP-IDF.
- **Damian Schneider ([dedehai](https://github.com/DedeHai))**: author of the WLED Particle System, whose emitters, forces and walls over one shared pool are the shape our [particle kernel](docs/moonmodules/light/power-functions.md#particles) and the scripted `pool` / `emit` / `step` builtins follow, in our own fixed-point implementation.

## Unreleased (`next-iteration`)

### 4 MB boards move to the MoonBase partition table (2026-08-26)

**Action: erase flash** (USB re-flash; all on-device config is lost and must be re-entered).

The 4 MB variants (`esp32`, `esp32-wrover`, `esp32-eth`) replace the dual-OTA layout with
[MoonBase](architecture.md#moonbase-the-second-boot-image-4-mb-boards): the app slot grows
1856 → 2496 KB and the filesystem 256 → 548 KB, but the filesystem moves (0x3B0000 → 0x360000),
so the existing volume is not where the new table looks, WiFi credentials, module config and
scripts all re-enter through provisioning. A partition table only changes over USB: a device
still on the old table keeps OTA-updating *within* that table for as long as the app fits its
1856 KB slot; the web installer is the migration path. 8/16 MB boards are unaffected.

### PreviewDriver's `fps` becomes `targetFps`, and now trades resolution (2026-08-25)

The control is renamed and its meaning changed, so the rename is the point rather than cosmetic.
