The app installs MoonBase, and every image says which one it is - #99
Conversation
Scripts can now define helpers that take parameters, which is what lets one function be called many times with different values instead of communicating through class members. Editing a shipped script still forks it, but the card now says whether your copy is current or the library has moved on, and the palette picker no longer offers a script it cannot select. Performance: desktop 1846 KB, ESP32 image 1,978,768 bytes (53% partition free), tick unchanged. 1879 unit tests (+24 cases), 27 scenarios, 0 failures. **Core** - MoonLive functions take arguments, by value. They pass through a block in the arena rather than the frame: each function opens its own frame and a slot is addressed off the current frame pointer, so a caller cannot reach its callee's slots at all on Xtensa's windowed ABI. No backend's call sequence changed. The callee copies its arguments out at entry, which is what lets ONE block serve every depth, recursion included. - The status line names a shadowing copy: `edited copy`, or `edited copy, shipped one updated` when the library has changed since the fork was made. Lineage is recorded on the write hook, so every writer gets it, and cleared on revert. Saving a shipped script unchanged now creates no copy at all. **Light domain** - Scripted palettes were listed but unselectable: the scan read only the user directory while the UI downloads to the factory one, and the control's ceiling was baked before the file arrived. Both fixed; the picker's retry and its "reopen the picker" message are gone. - Moving heads reach their beam: `setGobo`/`setRotate` on EffectBase and all five fixture roles from a script. MovingHeadEffect gains gobo, rotate and a beat-rolled pattern. - `draw::ring` and `draw::strokeLine`, sub-pixel and antialiased, and FixedPointEffect: eleven demos ported from Sutaburosu's fixed-point canvas. - Rings241 gains `angleFirst`; AudioVolume removed as too simple. **Scripts** - Three layouts (se16, lightcrafter16, sixteen-rings) and five moving-head scripts, prefixed `mh-` so a rig's scripts group together. - balls, crosshair, mh-sweep and ripples rewritten onto arguments. Verified byte-identical output over 8 frames; ripples got 22% smaller because naming the wave computes each source once instead of twice per pixel. **Tests** - Function arguments (by-value semantics, recursion, nested calls, arity), the palette scan and control ceiling, ring/strokeLine, the fork predicates. - scenario_modifier_chain uses PreviewDriver rather than NetworkSendDriver: a modifier-composition test had socket behavior in it (CodeRabbit #29). **Docs/CI** - The script comment rule names three places, one line each; all 52 scripts comply. MoonLive README documents forking and the three status states. **Reviews** - 🐇 CodeRabbit #29, scenario finding: fixed. Its `tick_us` half was dismissed with the reason recorded: a measure step records rather than asserts, and that recording is the per-commit performance trend. Not verified: the ESP32 firmware-fresh gate fails, correctly, because the S3 binary predates the new layout scripts. Function arguments ran on desktop, S3 and P4; the fork marker has only run on desktop. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Clamp calculated motion values before the uint8_t motion sink.
With valid controls such as pan = 0 and range = 127, the calculated value is negative. Conversion to the uint8_t motion-sink argument wraps it to 129. Values above 255 wrap in the same way.

Preserve and enforce parameter declarations.
parseParams accepts names that the expression parser resolves before locals. For example, void f(int width) reads the system width value instead of the passed argument.
The function record keeps only params. A call such as f(1) for void f(fixed x) copies raw 1 into a Q16.16 parameter. byte and bool parameters also bypass narrowing.
Reject parameter-name collisions as parseLocalDecl() does. Store each parameter type in FnMark. Validate or convert arguments before staging them. Reject unsupported string parameters.

Route the fade request through Layer.
draw::fade(cv, fade) fades the shared buffer once for this effect. If another effect also fades, the calls compound instead of using Layer's once-per-frame minimum collection. Trails then decay faster than either effect requested.
Call layer()->fadeToBlackBy(fade) instead.

- draw::fade(cv, fade);
+ layer()->fadeToBlackBy(fade);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

MoonBase is the recovery image that installs the app, and until now nothing installed MoonBase: a device whose recovery image was broken needed a cable. The app can now write it over the network, both images report their version so a drifted pair is visible at a glance, and the Firmware card describes and installs either image through one selector. Performance: desktop 1909 KB, ESP32 image 2,056,928 bytes, tick 170us (was 172). 1890 unit tests (+11 cases), 27 scenarios, 0 failures. Flash: esp32 +33 KB, esp32s3-n16r8 +15 KB for 1513 lines of new firmware code. **Core** - The app installs a new MoonBase into the factory partition, the mirror of MoonBase installing the app. esp_ota_* refuses a factory target, so this is a raw erase-and-write and esp_image_verify replaces the validation esp_ota_end used to give. A 4 MB board has nowhere to stage 743 KB, so the image streams straight in: everything that can reject it is therefore decided from the FIRST CHUNK, before a byte is erased. - Neither image may be installed as the other. A MoonBase image written into the app slot leaves both partitions holding MoonBase, and every route out then resolves to the partition being executed (0x1501) while the device still answers and serves a page: reachable, and recoverable only with a cable. Both images now refuse it, since either can be the one writing the app slot. - `core/FirmwareImage.h` parses an ESP32 image header without ESP-IDF, so the rules that guard an erase run in a host test. Shared with MoonBase, whose CMakeLists opens the include path for this one header rather than keeping a second hand-written copy of the format. - Every image carries its version already, in the app descriptor IDF emits. build_esp32 sets PROJECT_VER for both, so the app reads the factory partition's version without booting it and marks a mismatch. - MoonLive: `else if` chains, `for` with `<=`, and 40 IR labels (was 16, which bounded a script to eight loops). A parameter name is now checked the way a local is, so it cannot shadow a builtin or repeat another parameter. **Light domain** - StadBeest eyes and legs, two .mle effects for the art installation. - MovingHead: the gobo slot clamps instead of wrapping past 255, and goboOnBeat reads audio even with audioReactive off, where it previously did nothing. **UI** - One Firmware card for two images: an `image` control chooses which partition the four rows describe and the three install paths target, rendered as a tab strip. The install picker is shared with the web installer again, with URL and file rows on its own extras seam. - Every install shows progress: the device reports byte counts in its status for the paths it drives, and a browser-pushed upload drives the same overlay. - The file editor keeps editing the fork it just created, instead of comparing against the shipped file forever. **Scripts/MoonDeck** - `serve_firmware.py` serves a built image over HTTP/1.1. `python -m http.server` speaks 1.0, whose unframed body makes esp_https_ota crawl and then fail; that cost two OTA attempts before the response line was read. - check_nonblocking fails closed when an incremental run measures nothing, which it silently reported as zero findings. **Docs** - architecture gains the update mechanism; getting-started gains a MoonBase section for users, and MoonBase's help link points there rather than at the architecture page. - `soundReactive` is `audioReactive` in the effects catalog, six places. **Reviews** - 🐇 pan/tilt clamping in .mle scripts: skipped, byteArg already clamps 0..255. - 🐇 FixedPoint fade through the Layer: reverted and backlogged. The swap is right but the two calls mean different things (per-frame amount vs per- reference-frame rate), and it made the effect 3.1x brighter at high framerate against a 1.35x band. It needs its default re-tuned and the trail looked at. - 🐇 the remaining six findings fixed: docs Tests link, soundReactive naming, parameter name checks, gobo overflow, goboOnBeat audio, save() destination. - 👾 dead code removed (moonbaseAssetUrl, bytesRead_, two CSS classes, a do-nothing wrapper); stale comments corrected, including two that documented the URL install as synchronous when it is async.

1769-1788: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftParameter types are not enforced or converted at the call site.
parseParamsdeclares each parameter as aLocalwith itsCtrlType, so a read of the parameter inside the function body scales correctly. But this type never reaches the caller:FnMarkstores only aparamscount (Line 173), andparseCall's script-function branch (Lines 697-713) stages each argument's rawVRegwith no comparison against the callee's declared type.Calling

Abyteorboolparameter given an out-of-range argument is not narrowed either: the copy-out prologue inparseProgram(Lines 1901-1906) reloads and spills each argument without callingnarrowToType, unlikeparseLocalDecl, which narrows every local declaration.Store each parameter's
CtrlTypeinFnMarkalongsideparams. At the call site, convert or reject an argument the same way a builtin call'sfixedArgscheck does (Lines 837-844). Narrowbyte/boolarguments in the copy-out prologue the same wayparseLocalDeclnarrows a local.This is the same gap raised in a past review on this file.

- Around line 334-336: Update the MoonBase recovery and validation wording near
the upload-button description: state that cable-free updates require the running
app, while recovery needs a cable if the app is unavailable or MoonBase cannot
boot. Describe validation as checking the image magic, chip ID, and MoonBase
descriptor, using chip-specific wording instead of claiming physical
device-model validation.
In `@moonbase/main/moonbase_main.cpp`:
- Around line 613-620: Move upload identification in serveOne before
esp_ota_begin: buffer and read at least mm::firmware::kIdentifyBytes, reject
short or undescribed data and projectMM-moonbase images, then start OTA and
replay the buffered bytes through the existing write path.
In `@moondeck/run/serve_firmware.py`:
- Line 37: Update the server startup logic around the socket connect call so it
does not require a route to 8.8.8.8:80. Support an advertised-host override, and
when unavailable handle the connect OSError by obtaining a usable local address
without preventing the server from binding.
In `@src/core/HttpServerModule.cpp`:
- Around line 212-216: Update the isStreamingRoute matching for POST
/api/firmware/moonbase-update to require that the character immediately after
the 34-character route is the request-line space, preventing it from matching
the longer moonbase-update-url route while preserving streaming for the exact
route.
In `@src/core/moonlive/MoonLiveCompiler.cpp`:
- Around line 1769-1788: Update user-function call lowering to carry each
declared parameter’s Local::type and convert the corresponding value from
scriptArgOffset() using the same narrowToType and fixed-point assignment checks
as local declaration/assignment paths before StoreCtrl32 or its equivalent
copy-in operation. Ensure byte and bool arguments are narrowed and fixed
arguments are scaled before staging into callee slots; do not alter the
parameter-name validation block.
In `@src/light/effects/MovingHeadEffect.h`:
- Around line 150-153: The gobo hold logic using goboHold_ must be time-based
rather than decremented once per tick. Update the gobo hold state in the
surrounding MovingHeadEffect code to use a wrap-safe elapsed-time deadline or
accumulated elapsed milliseconds, preserving the documented two-second duration
regardless of render rate.
In `@src/platform/desktop/platform_desktop.cpp`:
- Line 1464: Update the desktop MoonBase operation around the src callback so it
immediately returns the unsupported result with zero byte counters without
invoking src or consuming caller-owned input; preserve direct FirmwareImage
validation in its test.
In `@src/platform/esp32/platform_esp32_ota.cpp`:
- Around line 536-545: Update the manual OTA download flow around
esp_http_client_fetch_headers and the status check to follow 3xx responses using
esp_http_client_set_redirection(), closing and reopening the client for each
redirect. Bound the redirect loop, refresh headers and status after reopening,
and retain the existing error handling for non-200 responses and cleanup
failures.
- Around line 312-321: Update the uploadPull vetting flow around vetted and
firmware::identify to accumulate a contiguous image prefix from offset zero
until firmware::kIdentifyBytes is available, without marking the image vetted or
writing buffered data prematurely. Run identification on that prefix, reject
MoonBase images before flushing, then write the buffered prefix and subsequent
chunks only after validation; reject uploads that end before the required prefix
is complete.
In `@src/platform/platform.h`:
- Around line 796-797: Update the declaration documentation for otaWriteMoonBase
to state that the operation is synchronous and blocks the render tick while
erasing and writing the image, and document that it returns false on desktop
builds. Keep the existing no-reboot distinction clear so callers do not infer
that the operation is non-blocking.
In `@test/unit/core/unit_moonlive_compiler.cpp`:
- Around line 246-252: Expand the test around the mode-based tick logic so it
runs with mode values 0, 1, 2, and 3, asserting each produces its corresponding
RGB value and exactly one branch writes it. Keep the existing test structure and
cover all arms of the mode conditional.

into FnMark alongside params, then update parseCall’s script-function branch to
convert or reject arguments using the same fixedArgs type handling as builtin
calls. In parseProgram’s parameter copy-out prologue, apply narrowToType for
byte and bool parameters as parseLocalDecl does, while preserving existing

Limit the recovery and validation claims.
A running app can update MoonBase without a cable. If the app is unavailable and MoonBase is not bootable, recovery requires a cable. The validator checks the image magic, chip ID, and MoonBase descriptor. It does not validate a physical deviceModel. Use chip-specific wording and state the recovery conditions.

💡 Result:
Yes, the esp_ota_begin function erases the specified target partition [1]. According to the official ESP-IDF documentation, when esp_ota_begin is called, it erases the partition to the specified image size [1]. If the image size is unknown or set to 0 (specifically using OTA_SIZE_UNKNOWN), the entire partition is erased [1]. This erasure is a necessary step to prepare the partition for receiving the new application image [1].

Validate the upload before esp_ota_begin.
esp_ota_begin(part, contentLen, ...) erases the target partition range before the current identification check runs. When the body arrives in a later TCP segment, serveOne can pass prefixLen == 0; mm::firmware::identify then reports described == false, so a valid MoonBase image can be written to and selected as the app slot. The device then requires USB recovery.
Read at least mm::firmware::kIdentifyBytes before esp_ota_begin. Reject short or undescribed images, reject projectMM-moonbase, then replay the buffered bytes after the OTA handle starts.

isStreamingRoute also matches /api/firmware/moonbase-update-url.
"POST /api/firmware/moonbase-update" is exactly 34 characters. The request line for /api/firmware/moonbase-update-url shares the same first 34 characters, since -url is appended right after. std::strncmp(req, "POST /api/firmware/moonbase-update", 34) therefore also matches that route.
This lets a Content-Length up to kContentLenMax (8 MB) on /api/firmware/moonbase-update-url skip the 413 rejection and instead buffer only a truncated prefix, even though handleMoonBaseUrl reads the whole body from buf and never streams the remainder off the socket.
Add a check that the character right after the match is the request-line space, so the two routes cannot collide.

Apply parameter conversion before staging each user-function argument. User-function calls store raw VReg values in scriptArgOffset() and copy them into the callee slots without using the declared Local::type. A reachable MoonLive script with byte or bool parameters can therefore receive an un narrowed value, while a fixed parameter can receive an unscaled integer; this differs from the existing local declaration and assignment paths, which apply narrowToType() and fixed-point conversion. Carry each parameter type into call lowering and apply the same assignment checks and conversion before StoreCtrl32 or during the equivalent copy-in path.

Buffer a contiguous image prefix before app-slot vetting.
uploadPull can provide fewer than firmware::kIdentifyBytes on the first callback. The current code sets vetted before firmware::identify can describe the image, then writes the chunk. Later callbacks start at later image offsets, so re-running identify on them does not inspect the image prefix. Buffer a contiguous prefix from offset zero until it is large enough for identification, then flush it only after the image passes. Reject an incomplete prefix at end of upload.

ESP-IDF esp_http_client_open esp_http_client_fetch_headers manual redirect esp_http_client_set_redirection disable_auto_redirect only applies to esp_http_client_perform
💡 Result:
In the ESP-IDF HTTP Client, the disable_auto_redirect configuration option and the function esp_http_client_set_redirection() are primarily designed for and integrated into the automatic handling workflow, which is typically triggered by esp_http_client_perform() [1][2][3]. Here is the breakdown of how these components work together: 1. Automatic Handling (esp_http_client_perform): When using esp_http_client_perform(), the client automatically processes HTTP 30x responses [1][2]. If disable_auto_redirect is false (default), the client internally calls esp_http_client_set_redirection() to update the URL and continue the request [2][4]. If disable_auto_redirect is set to true, the client skips this automatic call and instead dispatches an HTTP_EVENT_REDIRECT event to the user's event handler, allowing for manual intervention [1][5][2]. 2. Manual Redirect Handling: If you are using the manual streaming API (calling esp_http_client_open(), esp_http_client_fetch_headers(), etc., individually), you are responsible for managing the state of the connection [6]. The function esp_http_client_set_redirection() is a public API that can be called manually [5][7]. Its purpose is to take the redirection URL already stored in the client (from the last response) and apply it to the client's configuration [1][2]. However, be aware of the following: * Client State: Calling esp_http_client_set_redirection() will update the URL in the client handle [2][4]. If you intend to perform a redirect manually, you must still close the existing connection (using esp_http_client_close()) before opening a new one with the updated URL, as the current connection may not be valid for the new destination [8]. * Event Handler: When disable_auto_redirect is true, the HTTP_EVENT_REDIRECT event is triggered so you can extract the Location header yourself [2][8]. Many developers prefer to capture the redirect URL via the HTTP_EVENT_ON_HEADER event (looking for "location") rather than relying on the internal client->location state, as this provides more control [8]. * Looping Issues: Some older versions of ESP-IDF contained bugs where enabling disable_auto_redirect could lead to unexpected behavior in esp_http_client_perform() [9]. Always ensure you are using a recent version of ESP-IDF if you encounter issues with manual redirection handling [9]. In summary, disable_auto_redirect primarily affects the internal automation logic within esp_http_client_perform(), but the redirection mechanics (extracting the header and updating the URL) remain available for manual use if you are controlling the HTTP lifecycle yourself [1][2][8].

💡 Result:
In the ESP-IDF framework (including v6.1), the esp_http_client component provides two primary ways to interact with HTTP/S services: a high-level automated flow via esp_http_client_perform, and a low-level manual flow using individual API functions [1][2]. 1. High-Level Automated Flow: esp_http_client_perform The esp_http_client_perform function automates the entire request-response cycle [2][3]. - It performs: connection opening, data exchange (sending request and reading response), and connection closing (if required) [1][2]. - Blocking vs. Non-blocking: By default, it operates in a blocking manner. If the client is configured as asynchronous (is_async = true in esp_http_client_config_t), it operates in a non-blocking manner and returns immediately when encountering EAGAIN, EWOULDBLOCK, or EINPROGRESS, allowing the application to poll the function until the transaction is complete [2][4]. - Integration: This function internally calls the lower-level sequence: esp_http_client_open -> esp_http_client_write -> esp_http_client_fetch_headers -> esp_http_client_read -> esp_http_client_close [2][3]. 2. Low-Level Manual Flow For applications requiring granular control (such as streaming data), developers use individual component functions [1]: - esp_http_client_open: Opens the HTTP connection [1]. It accepts a write_len parameter (0 for read-only, -1 for chunked encoding, or a positive value for known content length) [1]. - esp_http_client_fetch_headers: Reads the server's response headers after the request is sent [1]. It returns the content-length and allows the developer to subsequently check the HTTP status code [1]. - esp_http_client_set_redirection: Manages HTTP redirects [5][6]. When called (often inside an event handler), it updates the client URL to the location provided by the server and increments a redirect counter [5]. Technical Notes - Thread Safety: These functions are not thread-safe; a single client handle must not be used simultaneously from multiple tasks [2][3]. - Redirection Logic: esp_http_client_set_redirection ensures that if the original connection is HTTPS, redirects are restricted to HTTPS targets to prevent protocol downgrade attacks [5]. - Source Code: The implementation for these APIs is located in components/esp_http_client/ in the ESP-IDF repository [7]. Headers are defined in esp_http_client.h [2].

Handle HTTP redirects in the manual OTA download path.
esp_http_client_open() and esp_http_client_fetch_headers() do not run the redirect loop used by esp_http_client_perform(). A GitHub release asset can return 302, which this status check rejects before reading the firmware. Handle 3xx responses with esp_http_client_set_redirection(), then close and reopen the client with a bounded redirect count.

Document that otaWriteMoonBase is synchronous and blocks the render tick.
otaWriteStream states this property directly above. otaWriteMoonBase runs the same way: HttpServerModule::handleMoonBaseUpload calls it from the HTTP handler, which executes on tick20ms inside Scheduler::tick. The call erases the whole factory slot and then writes the image, so it blocks rendering for the full install. Add that note here, plus the desktop false return, so a caller does not read the "does NOT reboot" difference as "does not block".
📝 Proposed doc addition
// Same producer-callback shape as otaWriteStream, and the same status vocabulary, with two
// differences that matter. It VETS the first chunk (magic, chip id, and that the image really is
// MoonBase) before erasing anything, so a wrong URL costs nothing. And it does NOT reboot: the
// running app is untouched, and the new image is simply what the device falls back to next.
+// SYNCHRONOUS, exactly like otaWriteStream: the caller is the HTTP request handler on the
+// tick20ms tick, so this blocks rendering for the erase + write duration. Accepted as
+// user-initiated work. Desktop: returns false; guard with `if constexpr (platform::hasOta)`.
bool otaWriteMoonBase(FsWriteSrc src, void* user, size_t contentLen,
char* statusBuf, size_t statusBufLen, uint32_t* bytesReadOut);As per path instructions: "blocking OTA operations must remain off the hot path or be explicitly documented as accepted user-initiated work".

Exercise every else if arm.
The test fixes mode at 0, so it only verifies the first arm. A regression in the mode == 1, mode == 2, or final else arm would still pass. Run the same case with each mode and assert that exactly one arm writes its value.
As per path instructions, unit tests must cover edge cases and match the specifications in docs/moonmodules/.

Nothing a user sees changes. The MoonBase install path refuses an image it cannot identify rather than one it merely recognizes as wrong, a MoonLive parameter behaves like the local it is, and the plans that shipped move to the archive. Performance: desktop 1909 KB, tick 140us. 1892 unit tests (+2 cases), 27 scenarios, 0 failures. **Core** - The app's upload path vets on ENOUGH bytes rather than on the first chunk. A producer handing back fewer than the descriptor needs made identify() report "no description" for an image that has one, so the guard passed and a MoonBase image could reach the app slot: the state that answers, serves a page, and needs a cable. MoonBase's own upload had the same hole. - The streaming allowlist matches `moonbase-update ` with its trailing space. Without it the prefix also matched `moonbase-update-url`, whose small JSON body was then truncated to the prefix buffer instead of read whole. - A MoonLive parameter narrows to its declared type in the callee prologue, so a `byte` parameter handed 300 wraps to 44 exactly as a `byte` local does. Done there rather than at each call site: the callee already knows the types. - One format-checked status writer. The three `setStatus` lambdas put the format string behind a variadic template, which is correct but not provable, and a code-scanning alert said so. A plain varargs function takes the printf format attribute, so a non-literal format is now a build error. **Light domain** - MovingHead's gobo hold is a millisecond deadline, not a frame count: 120 frames was two seconds at 60 fps and half a second at 240. - mh-sweep uses the `else if` chain the language change was added for, and the StadBeest scripts come back inside the comment budget this branch tightened. **UI** - The update badge ignores the card while it describes MoonBase, where it was comparing a recovery image's version against app releases. - The image tab strip gets its patch-path twin. Without it a WS patch could leave the strip naming one image while the buttons wrote the other. - An install with no byte counts (a chunked response) reports progress rather than hanging until the five-minute timeout. **Scripts/MoonDeck** - serve_firmware falls back when there is no route to the internet, which is exactly the bench network it is most useful on. **Tests** - Three script-resolve tests get their own filesystem root. They were writing into the developer's real /moonlive, which is the hazard the Rig in that same file was written to prevent. - A parameter declaration beyond the argument block is refused, byte narrowing is pinned, and the else-if test exercises every arm instead of only the first. - unit_FirmwareUpdateModule asserted inside a condition that could not be true after the control was renamed. **Docs** - MIGRATING gains the removed AudioVolume effect and the renamed firmware controls; system.md stops listing controls that no longer exist; the FixedPoint card gets the tags the code declares, its technical link and its tests link; serve_firmware is in MoonDeck.md. - Getting-started no longer says a device never needs a cable: the network update runs from the app, so it keeps MoonBase fresh rather than rescuing a device that will not start. - The shipped and superseded plans move to the archive, with OPEN-WORK.md listing what is left in the ones that stay. **Reviews** - 🐇 11 findings: 10 fixed, 1 partial (MoonBase vets after esp_ota_begin rather than before; the abort path commits nothing, so no bytes reach flash). - 👾 branch review: the parameter-block overrun, the tests writing to the real device directory, and the two UI findings above. - Code scanning 893 (cpp/non-constant-format): fixed, not waived.

Two things a device could not do before: install its own recovery image, and say which one it carries. Plus MoonLive gains the language pieces a mode-selecting effect needs, and the effects catalog grows.
The app installs MoonBase
MoonBase is the recovery image that installs the app. Nothing installed MoonBase, so a device whose recovery image was broken needed a cable. That is the one failure MoonBase exists to prevent, and the bench hit it: two identical S3 boards, one installing a 2 MB image in 15 seconds and one stalling at exactly 1024 bytes. Establishing why took a bisect of the git log, because no image reported a version.
Both halves are fixed. The app writes the factory partition while running from
ota_0, the mirror of MoonBase writing the app slot while running from factory: neither image can rewrite the partition it executes from, so each installs the other.esp_ota_*refuses a factory target, so this is a raw erase-and-write andesp_image_verifyreplaces the validationesp_ota_endused to give. A 4 MB board has nowhere to stage 743 KB, so the image streams straight in, which makes the ORDER of the checks the safety property: everything that can reject an image is decided from its first chunk, before a byte is erased. Point it at a 404 page, another chip's image, or an app firmware, and the device still has its MoonBase.Neither image may be installed as the other. Writing MoonBase into the app slot leaves both partitions holding MoonBase; every route out then resolves to the partition being executed (
0x1501) while the device still answers and serves a page. Reachable by one paste, recoverable only with a cable. Found by doing it, twice.One card, either image
The Firmware card was hardcoded to the app partition. An
imageselector makes the partition a parameter: the same four controls describe whichever image is chosen, and the same three install paths (a release, a URL, a file) target it. Rendered as a tab strip, sharing the install picker with the web installer rather than duplicating it.Every install shows progress, in all six combinations. The device reports byte counts in its status for the installs it drives; a browser-pushed upload drives the same overlay from its own upload progress.
MoonLive
else ifchains,forwith<=, and 40 IR labels (16 bounded a script to eight loops). Parameters are now checked the way locals are: a name cannot shadow a builtin or repeat another, abyteparameter narrows at 255 like abytelocal, and a declaration beyond the argument block's capacity is refused rather than reading past it.Effects
Moving-head effects, eleven Sutaburosu fixed-point demos, and the StadBeest eyes and legs for the art installation.
draw::ringanddraw::strokeLine, sub-pixel and antialiased.Verified
Both bench boards, every scenario: control sets on a MoonBase device and a dual-OTA one, the tab switch, all six install paths, and the three rejections with the recovery image intact afterwards. 1892 unit tests, 127 JS tests, 157 Python tests, zero warnings.
Reviews
CodeRabbit, the Reviewer agent and a code-scanning alert, all processed. Two were skipped with reasons: pan/tilt clamping in scripts (
byteArgalready clamps), and routing FixedPoint's fade through the Layer, which is right in principle but made the effect 3.1x brighter at high framerate against a 1.35x band, so it is backlogged with its own entry rather than shipped half-done.Alert 893 (
cpp/non-constant-format) is fixed rather than waived: the threesetStatuslambdas now delegate to one__attribute__((format(printf)))function, so a non-literal format is a build error instead of a scanner note.Note for review
113 files, past the ~100 where CodeRabbit declines a PR outright. 24 of those are scenario JSON recordings and 39 are plan-archive moves.
