A cosmetic change can ride on the run it followed, since the next commit's gates check it again. +On "run pre-commit", the agent runs [the commit process](docs/moonwalk.md#commit): each check the diff triggers, once, one line each PASS, FAIL or SKIP, then it stops. **A failure is something to report, not to fix and re-run.** **`check_docgen` is a ratchet**: errors stay at 0, warnings only fall, per rule and in total, and a touched file's warnings get resolved ([why](moondeck/MoonDeck.md#check_docgen)). -```mermaid -flowchart LR - pc{"๐Ÿง‘ run pre-commit

They run on request only, never as part of pre-commit, pre-merge or pre-release, and the `src/ui` trigger above means `--js` alone. - - -**`check_docgen` is a ratchet.** Errors are resolved before a commit, and warnings may only fall: the committed `docs/reference/metrics/docgen.md` is the number to beat, on the total and on every rule. It fails a run that raises either. Per rule as well as per total, because a total hides one rule paying for another, and because the cheapest way to satisfy a width rule is to split a line, which raises the block count and fixes nothing. A rule whose own limit changed is the one case to say so in the commit. - -**A file with warnings is left better than it was found, and the aim is zero.** Errors stay at 0, always. Holding the warning line is the floor, not the goal. The report shrinks only if each change spends effort on the warnings in the files it already touches. **A touched file that still has warnings gets all of them resolved, so the file leaves the list entirely.** Clearing a file beats shaving one finding off each of five: a file at zero stays there, where a file at four drifts back. Reasonable effort, in the spirit of principle 5: the ones a reader would agree with, not a rewrite of every comment in the file. What resists is left with its count unchanged rather than forced, since a comment split to satisfy a width rule is the move the per-rule ratchet exists to refuse. A file that cannot reach zero says in one line what remains and why. Cut first. Move only what neither the code, the test name nor the spec says, and prefer an existing home over a new appendix section. Files the change never opened are a sweep of their own. - -Three checks earn their place for a reason worth knowing. **Repo health** is the only place the creeping numbers are visible: flash and DRAM per target, binary size, the tick matrix, line counts, complexity warnings. Its diff belongs in the commit and its deltas in the commit message. It runs when the code changes rather than on every commit, because its timings drift with the host: on a docs-only diff it records a regression that nothing in the diff caused. **The no-backend build** catches a helper left unused outside its guard, fatal under GCC while clang stays silent. **ESP32 firmware fresh** compares the binary against every source in a tenth of a second and catches the edit that was never compiled; compile for real after an sdkconfig or toolchain change.

It helps the project get noticed. ## How we work -MoonLight is built by AI agents under tight human direction. Everything in this repository is authored by agents; the **product owner** writes none of it directly. What the product owner authors is the [process](CLAUDE.md), the [architecture](docs/explanation/architecture/index.md), and the [module specifications](docs/moonmodules/), then decides what to build, reviews every line, runs the hardware tests, and controls every commit and release. Agents write; the product owner thinks. - -The roles, the principles and the full process: [CLAUDE.md](CLAUDE.md). - -## History - -This is the current iteration of years of LED and light-system development, and each prior project proved ideas this one builds on: - -| Project | Description | Repo | -|---------|-------------|------| -| **WLED** | Open-source LED firmware (user and contributor since 2021) | [Aircoookie/WLED](https://github.com/Aircoookie/WLED) | -| **WLED-MoonModules** | WLED fork with advanced features | [MoonModules/WLED](https://github.com/MoonModules/WLED) | -| **StarLight** | Standalone LED firmware | [ewowi/StarLight](https://github.com/ewowi/StarLight) | -| **MoonLight** | Ground-up build: 60+ effects, memory-optimized mapping, 11 driver types | [ewowi/MoonLight](https://github.com/ewowi/MoonLight) | - -We built and maintained these, so MoonLight rests on our own hands-on experience. Their lessons are distilled in [`docs/work/past/`](docs/work/past/index.md).

Every smell has a named, behavior-preserving move from the refactoring catalog (Fowler, *Refactoring*), the vocabulary every IDE's refactor menu and every quality platform uses. The commit names the move it made, so a reviewer checks that the move was applied rather than whether the result looks simpler, and two people make the same change. -| Smell, what the report counts | The move | Where it lands | -|---|---|---| -| Long function | Extract Function | a named step a reader can skip | -| Deeply nested | Replace Nested Conditional with Guard Clauses; Extract Function on the inner loop | flat flow, one level at a time | -| Complex function: a conditional chain on one value | Replace Conditional with a table | data rows, no branches: a Command table | -| Complex function: a `switch` on a state | Replace Type Code with State: one method per state | the State pattern | -| Duplicated code | Extract Function, Pull Up Method | one home | -| Long parameter list | Introduce Parameter Object | one struct | -| Large file | Extract Class, Move Function | a module per concern | -| Core reaching into light | Move Function, or an interface in core that light implements | the dependency points inward | -| Platform code outside `src/platform` | Move Function into the platform layer; `if constexpr` on `platform_config.h` | a target's facts in one layer | -| A blocking call on the render path | Move the work off the render thread: a worker, a cached value, a deferred apply | the tick only computes | -| A name spread across files | Move Function, self-registration | a concept in one place | -| A module type named in the UI | Replace Conditional with Polymorphism: the module declares a control, a role or a flag | the UI knows no module | -| A stack frame over 512 bytes | Move the large local into a member or a `ScratchBuffer`, sized once | no task's stack pays for it | -| A buffer taken by hand in the light domain | Replace it with a `ScratchBuffer` member | owned, sized, reported and freed in one place | +Each rule of `check_code` carries its move, shown with the rule on [the test page](../reference/tests.md#check_code): the smell, the catalog move that solves it, and where the code lands. Cut first: a branch that chooses between equals is data, a guard is an early return, and nesting is what a reader trips on, more than branch count. The theory behind the moves is Ousterhout's: complexity is dependencies and obscurity, so a deep module with a small interface absorbs it and its callers stay simple.

It says so in one line, and its count stays rather than being forced. ### When checks run -Which checks run at which lifecycle event is defined once, in the [Commit](../CLAUDE.md#commit), [Merge](../CLAUDE.md#merge) and [Release](../CLAUDE.md#release) tables.

Vale carries the same 30 as a suggestion, so one number means one thing in both tools. **The appendix budget counts a SECTION, not the whole appendix.** A single total punishes a file for having several distinct topics. The cheapest way to satisfy one is to delete a section rather than tighten the prose. Ten lines per `##` section asks each one to be disciplined and lets a file carry as many as it genuinely has. That is what an implementation file needs: the platform backends each hold a handful of separately diagnosed findings, and one shared budget could only force them out of the tree. A fenced block does not count, the same exemption the no-wrap rule makes. A protocol listing is as long as the thing it describes, and counting its lines would ask an author to delete wire format to fit a prose budget. **No hard wrap in a comment, for the reason markdown gives.** Let the editor soft-wrap, so a one-word edit is a one-word diff rather than a reflowed paragraph. The one-line budget already forbids this on a header's member or code comment. So the rule bites where a block is allowed to be multi-line. That is the class comment, the `@technical` appendix, and any multi-line run in an implementation file. A list item, a heading, a table row and a fenced block are structure rather than a wrapped sentence, and each is left alone. This one holds everywhere, because its reason is the diff rather than the page. A split sentence reflows every line it spans when a word changes, which costs a reviewer the same in either file.
