Helps with aesthetic direction, typography, and making choices that don't read as templated defaults. -license: Complete terms in LICENSE.txt ---- - -# Frontend Design - -Approach this as the design lead at a small studio known for giving every client a visual identity that could not be mistaken for anyone else's. This client has already rejected proposals that felt templated, and is paying for a distinctive point of view: make deliberate, opinionated choices about palette, typography, and layout that are specific to this brief, and take one real aesthetic risk you can justify. - -## Ground it in the subject - -If the brief does not pin down what the product or subject is, pin it yourself before designing: name one concrete subject, its audience, and the page's single job, and state your choice. If there's any information in your memory about the human's preferences, context about what they're building, or designs you've made before – use that as a hint. The subject's own world, its materials, instruments, artifacts, and vernacular, is where distinctive choices come from. Build with the brief's real content and subject matter throughout. - -## Design principles - -For web designs, the hero is a thesis. Open with the most characteristic thing in the subject's world, in whatever form makes sense for it: a headline, an image, an animation, a live demo, an interactive moment. Be deliberate with your choice: a big number with a small label, supporting stats, and a gradient accent is the template answer, only use if that's truly the best option. - -Typography carries the personality of the page. Pair the display and body faces deliberately, not the same families you would reach for on any other project, and set a clear type scale with intentional weights, widths, and spacing. Make the type treatment itself a memorable part of the design, not a neutral delivery vehicle for the content. - -Structure is information. Structural devices, numbering, eyebrows, dividers, labels, should encode something true about the content, not decorate it. Many generic designs use numbered markers (01 / 02 / 03), but that's only appropriate if the content actually is a sequence - like a real process or a typed timeline where order carries information the reader needs. Question if choices like numbered markers actually make sense before incorporating them. - -Leverage motion deliberately. Think about where and if animation can serve the subject: a page-load sequence, a scroll-triggered reveal, hover micro-interactions, ambient atmosphere. An orchestrated moment usually lands harder than scattered effects; choose what the direction calls for. However, sometimes less is more, and extra animation contributes to the feeling that the design is AI-generated. - -Match complexity to the vision. Maximalist directions need elaborate execution; minimal directions need precision in spacing, type, and detail. Elegance is executing the chosen vision well. - -Consider written content carefully. Often a design brief may not contain real content, and it's up to you to come up with copy. Copy can make a design feel as templated as the design itself. See the below section on writing for more guidance. - -## Process: brainstorm, explore, plan, critique, build, critique again - -For calibration: AI-generated design right now clusters around three looks: (1) a warm cream background (near #F4F1EA) with a high-contrast serif display and a terracotta accent; (2) a near-black background with a single bright acid-green or vermilion accent; (3) a broadsheet-style layout with hairline rules, zero border-radius, and dense newspaper-like columns. All three are legitimate for some briefs, but they are defaults rather than choices, and they appear regardless of subject. Where the brief pins down a visual direction, follow it exactly — the brief's own words always win, including when it asks for one of these looks. Where it leaves an axis free, don't spend that freedom on one of these defaults. Just like a human designer who's hired, there's often a careful balance between doing what you're good at and taking each project as a chance to experiment and learn. - -Work in two passes. First, brainstorm a short design plan based on the human's design brief: create a compact token system with color, type, layout, and signature. Color: describe the palette as 4–6 named hex values. Type: the typefaces for 2+ roles (a characterful display face that's used with restraint, a complementary body face, and a utility face for captions or data if needed). Layout: a layout concept, using one-sentence prose descriptions and ASCII wireframes to ideate and compare. Signature: the single unique element this page will be remembered by that embodies the brief in an appropriate way. - -Then review that plan against the brief before building: if any part of it reads like the generic default you would produce for any similar page (work through a similar prompt to see if you arrive somewhere similar) rather than a choice made for this specific brief — revise that part, say what you changed and why. Only after you've confirmed the relative uniqueness of your design plan should you start to write the code, following the revised plan exactly and deriving every color and type decision from it. - -When writing the code, be careful of structuring your CSS selector specificities. It's easy to generate CSS classes that cancel each other out (especially with a type-based selector like .section and a element-based selector like .cta). This can happen often with paddings/margins between sections. - -Try to do a lot of this planning and iteration in your thinking, and only show ideas to the user when you have higher confidence it'll delight them. - -## Restraint and self-critique - -Spend your boldness in one place. Let the signature element be the one memorable thing, keep everything around it quiet and disciplined, and cut any decoration that does not serve the brief. Not taking a risk can be a risk itself! Build to a quality floor without announcing it: responsive down to mobile, visible keyboard focus, reduced motion respected. Critique your own work as you build, taking screenshots if your environment supports it – a picture is worth 1000 tokens. Consider Chanel's advice: before leaving the house, take a look in the mirror and remove one accessory. Human creators have memory and always try to do something new, so if you have a space to quickly jot down notes about what you've tried, it can help you in future passes. - -## More on writing in design - -Words appear in a design for one reason: to make it easier to understand, and therefore easier to use. They are design material, not decoration. Bring the same intentionality to copy that you would bring to spacing and color. Before writing anything, ask what the design needs to say, and how it can best be said to help the person navigate the experience. - -Write from the end user's side of the screen. Name things by what people control and recognize, never by how the system is built. A person manages notifications, not webhook config. Describe what something does in plain terms rather than selling it. Being specific is always better than being clever. - -Use active voice as default. A control should say exactly what happens when it's used: "Save changes," not "Submit." An action keeps the same name through the whole flow, so the button that says "Publish" produces a toast that says "Published." The vocabulary of an interface is the signposting for someone navigating the product. Cohesion and consistency are how people learn their way around. - -Treat failure and emptiness as moments for direction, not mood. Explain what went wrong and how to fix it, in the interface's voice rather than a person's. Errors don't apologize, and they are never vague about what happened. An empty screen is an invitation to act. - -Keep the register conversational and tuned: plain verbs, sentence case, no filler, with tone matched to the brand and the audience. Let each element do exactly one job. A label labels, an example demonstrates, and nothing quietly does double duty. diff --git a/.agents/skills/grilling/SKILL.md b/.agents/skills/grilling/SKILL.md new file mode 100644 index 0000000..8ca78c6 --- /dev/null +++ b/.agents/skills/grilling/SKILL.md @@ -0,0 +1,28 @@ +--- +name: grilling +description: Grill the user relentlessly about a plan, decision, or idea.

Often a legitimately flat peer-set (every rule of a review on one rung), which is a fine arrangement, not a smell. +3. **Disclosed reference** is pushed out into a separate file, reached by a context pointer, loaded only when the pointer fires. Spans a sibling file in the same folder through fully external reference that lives anywhere and any document can point at. + +Push too little down and the top bloats; push too much and you hide material the agent actually needs.

Not primarily a token optimisation: it is how the hierarchy is protected. Branching is the cleanest disclosure test: inline what every branch needs, and push behind a pointer what only some branches reach. When a document has steps, in-file reference that should be disclosed buries them and turns attending to them into a coin-flip: a variance lever, not just a legibility one. + +**Co-location** is the within-file companion: where the ladder decides _how far down_ a piece sits, co-location decides _what sits beside it_ once there.

Defend in order: **sharpen the bound first** (local and cheap); only if it is irreducibly fuzzy _and_ you observe the rush, hide the later steps by splitting the sequence. Hiding only works across a real context boundary (a hand-off or a subagent dispatch; an inline call leaves the later steps in context and clears nothing). +- **Demand**: how much it requires. "Every modified model accounted for" forces thorough work where "produce a change list" does not. Demand drives **legwork** (the digging the agent does within the work, latent in the wording rather than written as its own step), and it is not step-bound: "every rule applied" binds a body of flat reference just as "every step done" binds a sequence, which is how an all-reference document still carries an exhaustiveness bar. + +The strongest criteria are both checkable and exhaustive. + +## When to split + +Splitting one document into two spends one of the two loads, so split only when the cut earns it: + +- **By sequence**: split a run of steps where the post-completion steps tempt the agent to rush the one in front of it.

Beware the reverse: merging sequences exposes each step's later steps to what follows, inviting premature completion. +- **By invocation**, skill-specific: see [`SKILL-MECHANICS.md`](SKILL-MECHANICS.md). + +## Leading words + +A **leading word** is a compact concept already living in the model's pretraining that the agent thinks with while running the document (_lesson_, _fog of war_, _tracer bullets_). Repeated as a token, never as a sentence, it accumulates a distributed definition and anchors a whole region of behaviour in the fewest tokens, by recruiting priors the model already holds. Coining your own works if you define it clearly, but a made-up word recruits no priors: you pay in definition tokens what a pretrained word gives free; reach for an existing word first. + +It anchors twice. In the body, _execution_: the agent reaches for the same behaviour every time the word appears, and inside flat reference it focuses attention on a class of thing to look for. In a pointer, _invocation_: when the same word lives in your prompts, your docs, and your codebase, the agent links that shared language to the material and reaches it more reliably. + +Hunt for opportunities to refactor with leading words. A triad spelled out at three sites, a pointer spending a sentence to gesture at one idea. Each is a passage begging to collapse into a single token: + +- "fast, deterministic, low-overhead" → _tight_ (a _tight_ loop). +- "a loop you believe in" → _red_, turning a fuzzy gate into a binary observable state (the loop goes _red_ on the bug, or it doesn't). + +You win twice: fewer tokens, and a sharper hook for the agent to hang its thinking on. Assume every document is carrying restatements that leading words retire. Go find them. + +**Negation** is the failure mode beside this lever: steering by prohibition drags the forbidden behaviour into context and makes it _more_ available, not less. _Don't think of an elephant_, and the elephant is all there is; the negation is a weak modifier the strongly-activated concept overruns, so the ban half-reads as an instruction to do the thing. Prompt the **positive**: state the target behaviour ("write one-line comments") so the banned one is never spoken. A prohibition earns its place only as a hard guardrail you cannot phrase positively; even then, pair it with the positive target so attention lands on what to do. + +## Pruning + +- Keep each meaning in a **single source of truth**: one authoritative place, so changing the behaviour is a one-place edit. **Duplication** (the same meaning in more than one place) costs maintenance and tokens, and inflates a meaning's prominence on the ladder past its real rank. (The accidental inverse of a leading word, which repeats a token on purpose, never the meaning.) +- The **environment** is a source of truth too (`package.json` scripts, config files, the directory layout, `--help` output), and a document that restates it is a **cache**: a copy of a lookup, earning its load only when the lookup is expensive. Cache what the agent cannot find by looking: the unwritten convention, the reason behind a choice, the gotcha no config confesses. Leave the one-file, one-command lookups to the environment, where they cannot go stale. +- Check every line for **relevance**: does it still bear on what the document does? A line loses relevance by never bearing on the task (mere exposition, or a branch that should be disclosed) or by going stale as the behaviour or world it describes changes. Shorter documents are easier to keep relevant. Without a pruning discipline the default fate is **sediment**: stale layers that settle because adding feels safe and removing feels risky, until you must core down through them to find what is still live. +- Hunt **no-ops** sentence by sentence: an instruction the model already obeys by default pays load to say nothing. The test (does it change behaviour versus the default?) is model-relative, not reader-relative: two people disagreeing about a no-op disagree about the default, and settle it by running the document, not by debate. When a sentence fails, delete the whole sentence rather than trim words from it. The test also grades leading words: a word too weak to beat the default (_be thorough_ when the agent is already thorough-ish) is a no-op, and the fix is a stronger word (_relentless_), not a different technique. diff --git a/.agents/skills/writing-for-agents/agents/openai.yaml b/.agents/skills/writing-for-agents/agents/openai.yaml new file mode 100644 index 0000000..079c933 --- /dev/null +++ b/.agents/skills/writing-for-agents/agents/openai.yaml @@ -0,0 +1,3 @@ +interface: + display_name: "Writing for Agents" + short_description: "Write documents agents consume" diff --git a/.claude/skills/codebase-design b/.claude/skills/codebase-design new file mode 120000 index 0000000..08b466e --- /dev/null +++ b/.claude/skills/codebase-design @@ -0,0 +1 @@ +../../.agents/skills/codebase-design \ No newline at end of file diff --git a/.claude/skills/diagnosing-bugs b/.claude/skills/diagnosing-bugs new file mode 120000 index 0000000..b2134ff --- /dev/null +++ b/.claude/skills/diagnosing-bugs @@ -0,0 +1 @@ +../../.agents/skills/diagnosing-bugs \ No newline at end of file diff --git a/.claude/skills/domain-modeling b/.claude/skills/domain-modeling new file mode 120000 index 0000000..e672a60 --- /dev/null +++ b/.claude/skills/domain-modeling @@ -0,0 +1 @@ +../../.agents/skills/domain-modeling \ No newline at end of file diff --git a/.claude/skills/grill-with-docs b/.claude/skills/grill-with-docs new file mode 120000 index 0000000..f6cbb9c --- /dev/null +++ b/.claude/skills/grill-with-docs @@ -0,0 +1 @@ +../../.agents/skills/grill-with-docs \ No newline at end of file diff --git a/.claude/skills/grilling b/.claude/skills/grilling new file mode 120000 index 0000000..e712452 --- /dev/null +++ b/.claude/skills/grilling @@ -0,0 +1 @@ +../../.agents/skills/grilling \ No newline at end of file diff --git a/.claude/skills/handoff b/.claude/skills/handoff new file mode 120000 index 0000000..a34a6b2 --- /dev/null +++ b/.claude/skills/handoff @@ -0,0 +1 @@ +../../.agents/skills/handoff \ No newline at end of file diff --git a/.claude/skills/improve-codebase-architecture b/.claude/skills/improve-codebase-architecture new file mode 120000 index 0000000..be3dac9 --- /dev/null +++ b/.claude/skills/improve-codebase-architecture @@ -0,0 +1 @@ +../../.agents/skills/improve-codebase-architecture \ No newline at end of file diff --git a/.claude/skills/tdd b/.claude/skills/tdd new file mode 120000 index 0000000..2178bb8 --- /dev/null +++ b/.claude/skills/tdd @@ -0,0 +1 @@ +../../.agents/skills/tdd \ No newline at end of file diff --git a/.claude/skills/unslop b/.claude/skills/unslop new file mode 120000 index 0000000..158c16b --- /dev/null +++ b/.claude/skills/unslop @@ -0,0 +1 @@ +../../.agents/skills/unslop \ No newline at end of file diff --git a/.claude/skills/wait-what b/.claude/skills/wait-what new file mode 120000 index 0000000..a959f0c --- /dev/null +++ b/.claude/skills/wait-what @@ -0,0 +1 @@ +../../.agents/skills/wait-what \ No newline at end of file diff --git a/.claude/skills/writing-for-agents b/.claude/skills/writing-for-agents new file mode 120000 index 0000000..90df155 --- /dev/null +++ b/.claude/skills/writing-for-agents @@ -0,0 +1 @@ +../../.agents/skills/writing-for-agents \ No newline at end of file diff --git a/.dockerignore b/.dockerignore new file mode 100644 index 0000000..ecee47e --- /dev/null +++ b/.dockerignore @@ -0,0 +1,15 @@ +.git +.github +.husky +.idea +.vscode +.claude +.agents +.env* +!.env.example +node_modules +.output +.nitro +.tanstack +coverage +dist diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 03c7768..5048dfc 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -22,4 +22,7 @@ jobs: node-version-file: .nvmrc cache: pnpm - run: pnpm install --frozen-lockfile + # Worker, OPFS and codec tests run in Chromium through Vitest browser mode. + - run: pnpm exec playwright install --with-deps chromium - run: pnpm validate + - run: docker build -t hexlode:ci . diff --git a/AGENTS.md b/AGENTS.md deleted file mode 100644 index 2cd3edb..0000000 --- a/AGENTS.md +++ /dev/null @@ -1,69 +0,0 @@ -# Hexlode Agent Guide - -## Project - -- TanStack Start application using React 19, TypeScript, Vite, Tailwind CSS, and Astryx. -- PostgreSQL access uses Drizzle ORM.

Users connect nodes to build a -reusable workflow, run images through it, compare the results, and save the workflow for later. +Hexlode is an open-source image-processing app that runs in the browser. It has two levels: -The central promise is: +- Quick tools do one common job on a simple page: drop images, pick settings, download. +- The Studio is a node editor for batch work. Users drag nodes onto a canvas, connect them into + branching pipelines, run hundreds of images through them, and save the pipeline for reuse. -> Build an image-processing recipe once. Drop new images into it whenever you need it. +Version 1 processes everything on the user's device. A signed-in cloud mode with credits may come +later. The project is open source first: someone who finds the repository should be able to clone +it, run `pnpm install` and `pnpm dev`, and use it. -Hexlode should begin as a focused side project and open-source community tool. It should be useful -without an account, work locally by default, and remain manageable in a single application. +## Users -## 2. Why It Should Exist +Anyone who converts, compresses or resizes images, and people who repeat the same image work on +large batches: photographers, web developers, designers, shop owners and content creators. -Existing image tools usually trade away one of the things users care about: +## Home page -- Simple web converters often upload files to a server. -- Private browser tools tend to support one file and one operation at a time. -- Powerful desktop tools require installation and are cumbersome for repeatable jobs. -- Node-based tools often use the graph as decoration rather than representing real computation. +The home page shows the name and five text links: Convert, Compress, Resize, Strip metadata and +Studio. It has no hero section, marketing copy or feature grid. Saved pipeline tools appear under +the five links once the user has some. -Hexlode combines local processing with reusable visual workflows. Its retention loop is: +## Quick tools -1. Open a working starter pipeline. -2. Drop in an image and receive a result immediately. -3. Branch or adjust the pipeline and compare outputs. -4. Save the result as a reusable recipe. -5. Return with a new image or batch. +| Tool | Job | +|---|---| +| Convert | Change format: JPEG, PNG, WebP, AVIF, JPEG XL or QOI. | +| Compress | Reduce file size by quality setting or by target size. | +| Resize | Change dimensions by width, height, percent or longest edge. | +| Strip metadata | Remove all metadata, only location data, or everything except copyright. | -## 3. Positioning +Each quick tool is a fixed pipeline that runs on the same engine as the Studio. A quick tool page +has a drop area, the settings for that job, a results list with before and after sizes, and a +download button. A single result downloads as the file itself; several download as a ZIP. +Compress by quality never returns a file larger than the original. -Primary positioning: +A pipeline tool is a saved Studio pipeline opened as a quick tool page. The user builds the +pipeline once, then drops new images into the simple page whenever they need it. -> A private visual workspace for converting, inspecting, optimizing, and comparing images. +## Studio -Supporting promise: +The Studio is for desktop screens. Phones and narrow windows get a message that points them to the +quick tools. -> No account required. Process on your device by default. Use cloud processing only when you -> explicitly choose it. +### Layout -The application should feel like a creative technical instrument, not a collection of unrelated -converter pages. +- A sidebar lists every node type by category. The user drags a node onto the canvas or searches + for it by name. +- The canvas holds the pipeline. Any output can connect to several nodes, so a pipeline branches + like a tree. +- An inspector panel shows the full settings of the selected node. +- A new Studio opens a template picker: Web-ready photos, Responsive image set, Watermark and + compress, Instagram carousel, and Blank. -## 4. Product Principles +### What the canvas shows -### 4.1 The canvas is the product +The canvas shows real engine data so the user can see the work happening: -The node canvas is the main interface. Documentation, settings, saved recipes, and account pages -support it; they do not replace it. - -### 4.2 Never start empty - -The first visit opens a working pipeline: - -```text -Files -> Inspect -> Resize -> WebP -> Compare -> Download -``` - -A new user should get an output without first learning the graph editor. - -### 4.3 Local-first is the default - -Anonymous users can run the full local workflow. Image bytes, filenames, thumbnails, metadata, and -file-linked hashes must not enter analytics or backend services during local processing. - -### 4.4 Cloud processing is explicit - -Cloud processing may later help with very large batches or expensive operations, but it is never a -silent fallback. Before a remote job begins, the user must see what will be uploaded, why, expected -cost or quota use, retention, and deletion behavior. - -### 4.5 Simple by default, deep by choice - -Nodes expose safe defaults first. Advanced codec, metadata, and quality controls belong in an -inspector rather than crowding every node. - -### 4.6 Feature-rich does not mean over-engineered - -Hexlode stays one application. Product logic is organized by feature inside `src/`; it is not split -into packages merely because it may be reusable someday. - -### 4.7 Own the product logic, not industry standards - -Hexlode should own its graph validation, execution planning, batch policy, comparison experience, -constraint search, recipe model, and privacy controls. It should use mature libraries for image -codecs, archives, cryptography, authentication, databases, and other difficult standards. - -We will not rewrite JPEG, PNG, WebP, AVIF, HEIC, or similar codecs from scratch. A focused custom -transform is reasonable only when it provides a measured advantage and remains maintainable. - -## 5. Privacy and Execution Modes - -### 5.1 Private Session - -- No account. -- No analytics. -- No cloud processing or remote integrations. -- No persistent recipes, history, or temporary outputs. -- Processing remains on the device. - -This is the best mode for sensitive or one-off images. - -### 5.2 Local Workspace - -- Default mode; no account required. -- Processing remains on the device. -- Recipes, preferences, and lightweight run history are saved locally. -- Recipes can be imported and exported. -- The core workflow should remain usable offline after required assets are cached. - -### 5.3 Airgap Mode - -Private Session and Local Workspace can enable a visible Airgap Mode. It disables analytics, remote -inputs, cloud features, and optional integrations. The UI should make this enforcement clear rather -than relying on marketing copy. - -### 5.4 Synced Workspace — later - -An optional account may eventually synchronize recipes, macros, settings, and versions. Images and -their metadata stay local by default. Signing in must never become permission to use the core app. - -### 5.5 Cloud Assist — later and opt-in - -Cloud processing is intended for workloads such as hundreds of images, slow experimental codecs, -or operations that would exhaust a device. If introduced: - -- Each job requires an explicit remote-processing choice. -- A generous free allowance should cover ordinary community use. -- Any charges should recover real compute cost, not create artificial product limits. -- Local processing must not be weakened to promote cloud usage. -- Failed retries must not silently extend retention or duplicate charges. - -## 6. Core Experience - -### 6.1 Canvas behavior - -The editor should eventually support: - -- Pan, zoom, selection, connection, deletion, and duplication. -- Undo and redo. -- Typed ports and visibly rejected invalid connections. -- Search or command-palette node insertion. -- Node configuration through an inspector panel. -- Real execution state on nodes and edges. -- Keyboard access for essential workflows. -- A simpler non-canvas representation when accessibility or narrow screens require it. - -Advanced grouping, minimaps, auto-layout, macros, and rich edge animation should follow the working -pipeline rather than block it. - -### 6.2 Runtime states - -Nodes should share a small, consistent state model: - -- Idle or waiting. -- Invalid. -- Ready or queued. -- Processing. -- Complete, warning, or failed. -- Cancelled. -- Cached or dirty after upstream changes. - -Edges may show file count, bytes, savings, and active status when those values come from the real -execution engine. - -### 6.3 Typed workflow data - -Start with only the types required by implemented nodes: - -- `Image` -- `ImageBatch` -- `Metadata` -- `Boolean` -- `Number` -- `String` -- `FileBundle` -- `ErrorBatch` - -Add another type only when a real feature needs it. - -## 7. Product Scope - -### 7.1 First useful release - -The first release should make one excellent local workflow reliable: - -```text -Files -> Inspect -> Resize -> WebP -> Compare -> Download -``` - -Required capabilities: - -- File selection and drag-and-drop. -- Input inspection and basic safety checks. -- Resize and orientation correction. -- WebP output with useful defaults. -- Before-and-after preview and file-size comparison. -- Progress, cancellation, controlled errors, and download. -- A starter graph that can be edited and saved locally. - -### 7.2 Core expansion - -Once the first pipeline is dependable, add features in response to actual workflows: - -- JPEG and PNG output, then AVIF if the adapter proves reliable. -- Metadata inspection and selective removal, including GPS. -- Crop, rotate, transparency handling, and background behavior. -- Branching and filtering. -- Folder input, bounded batch processing, naming templates, and ZIP output. -- Recipe import, export, duplication, and run history. - -HEIC input, animation, colour-profile conversion, and uncommon formats require separate correctness -and licensing decisions. - -### 7.3 Signature features - -These distinguish Hexlode, but they should build on proven processing primitives. - -#### Codec Tournament - -Run selected encoders and settings against the same input, then compare size, processing time, -quality, transparency, and compatibility. Users can pick a result or pass it to Select Best. - -#### Constraint Solver - -Let users specify an outcome such as “under 200 KB, at least 1600 px wide, preserve transparency.” -Search must be bounded, cancellable, deterministic for fixed inputs, and able to explain failure. - -#### Visual Difference Lab - -Provide side-by-side, slider, synchronized zoom, pixel difference, heatmap, and perceptual comparison -only as those primitives become trustworthy. - -#### Macro Nodes - -Allow a selected subgraph to become a named reusable node. Versioning and nested macros can wait -until simple local macros work reliably. - -#### Pipeline Debugger - -Show real inputs, outputs, durations, warnings, failed files, cache state, and invalidation reasons. -Do not display estimates as if they were observed runtime facts. - -### 7.4 Experimental Labs - -Potential Labs features include background removal, upscaling, OCR, redaction, smart crop, local ML, -GPU transforms, palette extraction, duplicate detection, dithering, and experimental codecs. - -Labs features must be clearly labelled, disclose whether they are local or remote, and have a safe -fallback or a clear unsupported state. - -## 8. Recipes and Local History - -A recipe is versioned JSON describing nodes, connections, and settings. Visual positions should be -separable from execution meaning so layout changes do not alter results. - -Recipes should support: - -- Local save, duplicate, rename, import, and export. -- A schema version and migrations when the format changes. -- Small-file sharing without an account where practical. -- Run metadata such as settings, durations, output sizes, warnings, and engine versions. - -Source image bytes should not be retained unless the user explicitly enables local caching. - -## 9. Technical Direction - -### 9.1 One repository, one application - -Hexlode remains a standard TanStack Start application. Use a Bulletproof React-style feature layout -inside the existing repository: - -```text -src/ - routes/ Route definitions and composition - features/ - canvas/ Graph editing and node presentation - processing/ Planning, workers, codecs, progress, cancellation - image-input/ File and folder acquisition and inspection - recipes/ Recipe schema, persistence, import, and export - comparison/ Preview and difference tools - privacy/ Session mode, Airgap Mode, and remote-boundary UI - cloud-processing/ Optional remote jobs, only when implemented - components/ Truly shared application components - integrations/ Framework and third-party providers - lib/ Small cross-feature utilities - db/ Drizzle schema and database access -``` - -Each feature should contain only the folders it needs, such as `components`, `hooks`, `schemas`, -`services`, `types`, or `utils`. Do not scaffold every folder in advance. - -### 9.2 Separation without packages - -React components edit and display the workflow. Processing, graph validation, recipe parsing, and -worker messages should remain plain TypeScript within their feature modules. That separation makes -the code testable without creating a monorepo or public SDK. - -Extract a package only when an independently shipped second consumer actually exists and sharing -source directly is no longer workable. - -### 9.3 Current stack - -- TanStack Start, React 19, TypeScript, and Vite. -- React Flow for the canvas. -- Astryx and Tailwind for the interface. -- Web Workers for heavy browser work. -- Proven browser or WebAssembly codec libraries selected per format. -- IndexedDB for local structured persistence; OPFS only if large intermediates justify it. -- Drizzle and PostgreSQL for future account and cloud data. -- Better Auth for optional accounts when synchronization exists. -- PostHog and Sentry with privacy-safe configuration. - -### 9.4 Processing rules - -- Never process large images on the React render path. -- Validate file signatures, dimensions, and estimated allocations before decoding. -- Bound concurrency by memory pressure as well as CPU availability. -- Support progress and cancellation from the first real pipeline. -- Lazy-load expensive codecs. -- Prefer transferable buffers and release intermediates promptly. -- Add SIMD, multithreaded WebAssembly, OPFS, or WebGPU only after measurement. - -## 10. Analytics, Security, and Accessibility - -Analytics may record coarse product events such as a node being added or a pipeline completing. It -must not record file content, names, paths, metadata, thumbnails, or file-linked identifiers. -Analytics is disabled in Private Session and Airgap Mode. - -Image inputs are untrusted. Dimension limits, allocation limits, malformed-file handling, codec -updates, and a restrictive processing boundary are core product requirements. - -Essential controls need labels, visible focus, keyboard operation, sufficient contrast, and reduced -motion. Advanced canvas accessibility should grow alongside real editor functionality. - -## 11. Explicit Non-Goals - -Not planned for the initial product: - -- A monorepo or internal package ecosystem. -- Public SDK, CLI, plugin SDK, or GitHub Action product. -- Reimplementing mature image codecs in JavaScript, Rust, C, or C++. -- Mandatory accounts, subscriptions, billing, or cloud processing. -- A desktop application or editor extension. -- A plugin marketplace or public recipe registry. -- Collaboration or organization management. -- A Photoshop replacement. -- Every image format and every browser capability at once. -- Browser automation suites before they solve a demonstrated regression risk. -- GPU or AI features without a measured product benefit. - -These are not permanent prohibitions. They require proven demand and a clear maintenance case. - -## 12. Success Criteria - -Hexlode is succeeding when: - -- A new visitor gets a useful output from the starter graph in minutes. -- Ordinary use works anonymously and locally. -- Users save and reuse recipes rather than rebuilding the same workflow. -- Batch jobs remain responsive and do not cause uncontrolled memory growth. -- Privacy and remote-processing boundaries are visible and technically enforced. -- New features fit the existing application without multiplying repositories or packages. - -## 13. Open Decisions - -- Final visual identity and public licence. -- First supported browser and mobile baseline. -- Exact initial JPEG, PNG, WebP, and AVIF implementations. -- Quality metric used by Codec Tournament and Constraint Solver. -- HEIC licensing and decoder choice. -- Local cache limits and retention defaults. -- When anonymous usage demonstrates a need for recipe sync or cloud batches. - -## 14. North Star - -> Drop -> experiment visually -> compare -> save the recipe -> reuse. - -Build the smallest dependable version of that loop first. Add depth when it makes the loop better, -not because a future platform can be imagined. +- Each node shows a live preview thumbnail of its output for a sample image the user picks; the + first image added is the sample until the user picks another. Previews run on a copy scaled to + 1024 pixels. The preview updates when a setting changes. The full batch runs only when the user + presses Run. +- During a run, each node shows counts (processed, skipped, failed), bytes in and out, and time. +- Connections animate while items flow and carry small labels: item count, formats such as + "PNG only", and size saved. +- The React Flow attribution is hidden. + +### Compatibility rules + +Each node declares which items it accepts and which it produces. The Studio uses these +declarations to keep pipelines valid: + +- A connection is refused when the upstream node can never produce anything the downstream node + accepts. The message says why and suggests a fix, for example "Optimize PNG needs PNG images. + Add Convert to PNG before it." +- A connection that narrows the stream is allowed. The connection gets a label such as "PNG only" + and a toast explains that other formats skip this branch. +- The Files node accepts every format that at least one branch can handle. It refuses files that + no branch can use and says which formats the pipeline accepts. +- During a run, an item that a node cannot accept skips that branch and continues through the + other branches. Skips are counted and shown separately from failures. + +### Runs + +- A run processes items on the device in Web Workers. The interface stays responsive. +- Before a run the Studio shows an estimate, for example "about 2,000 encodes, roughly 12 minutes + on this device". +- There is no limit on the number of files. Single images that are too large to decode safely are + refused with a clear reason. +- Each node keeps a step cache of its last results. When the user changes a setting and runs + again, only that node and the nodes after it run. +- The user can cancel a run. Items already finished stay available. + +### Output nodes + +An Output node saves every item that reaches it into browser file storage and passes the same item +on to the next nodes at the same moment. Output never slows the pipeline. When the last item +arrives, Output builds a ZIP from storage and shows a Download button. An Auto-download switch on +the node downloads the ZIP as soon as it is ready; it is off by default. A pipeline can have +several Output nodes, and each delivers on its own. Output can also save straight into a folder in +browsers that allow it. + +## Node catalogue + +Items are images, data (JSON or text) or documents (PDF). Batch numbers match the phases in +[implementation.md](./implementation.md). + +### Input and routing + +| Node | What it does | Batch | +|---|---|---| +| Files | Takes dropped files or a folder. Starts every pipeline. | 1 | +| Filter | Routes items by rules on format, file size, dimensions, orientation or transparency. Each rule has its own output, plus an output for everything else. An item leaves by the first rule it matches. | 1 | +| Inspect | Shows format, dimensions, size and metadata per item. Passes items through unchanged. | 1 | +| Deduplicate | Drops exact duplicates, or near duplicates by image fingerprint. | 2 | + +### Size and shape + +| Node | What it does | Batch | +|---|---|---| +| Resize | Resizes by width, height, percent or longest edge, with fit, fill or exact modes and a choice of resampling method. | 1 | +| Crop | Crops to an aspect preset (1:1, 4:5, 16:9 and others), from the centre or a chosen position. Turns the image upright first. | 1 | +| Rotate / Flip | Rotates and flips, including automatic rotation from the camera orientation tag. | 1 | +| Auto-trim | Removes plain-colour or transparent borders. | 2 | +| Pad / Extend | Adds space to reach an aspect ratio, filled with a colour or a blurred copy of the image. | 2 | +| Pixel-art upscale | Enlarges pixel art 2x to 4x with sharp edges. | 2 | +| Split / Tile | Cuts one image into a grid of images. | 2 | + +### Colour and look + +| Node | What it does | Batch | +|---|---|---| +| Adjust | Changes brightness, contrast, saturation and exposure. | 2 | +| Filters | Applies grayscale, sepia, duotone or invert. | 2 | +| Sharpen / Blur | Sharpens, or blurs the whole image or a region. | 2 | +| Background | Replaces transparency with a colour. | 2 | + +### Overlays + +| Node | What it does | Batch | +|---|---|---| +| Text watermark | Places text with position, size, opacity and an optional repeated tile. | 2 | +| Image watermark | Places a logo (PNG, WebP or SVG) with position, scale and opacity. | 2 | +| Border / Rounded corners | Adds a frame or rounds the corners. | 2 | + +### Metadata + +| Node | What it does | Batch | +|---|---|---| +| Strip metadata | Removes all metadata, only location data, or everything except copyright, without re-encoding. Keeps the colour profile unless told otherwise, and keeps a camera orientation tag so photos stay upright. | 1 | +| Set copyright / author | Writes author and copyright fields. | 3 | + +### Output and encoding + +| Node | What it does | Batch | +|---|---|---| +| Convert | Encodes to WebP, AVIF, JPEG, JPEG XL, PNG or QOI with the encoder's real settings, or keeps each item's format. | 1 | +| Compress to size | Finds the highest quality that fits a target size such as 200 KB. | 1 | +| Optimize PNG | Makes PNG files smaller without changing pixels. | 1 | +| Rename | Names files from a template such as `{name}-{width}w`. The extension follows the format. Output numbers duplicate names. | 1 | +| Output | Saves items, passes them on, and delivers a ZIP or folder. | 1 | +| Compare | Shows a before and after slider and the size difference. Passes items through. | 1 | +| Best format | Encodes several formats and keeps the smallest. | 3 | +| Responsive set | Makes several widths and a ready `srcset` HTML snippet. | 3 | +| Favicon / App icons | Makes every favicon and app icon size from one image. | 3 | +| Placeholder | Generates a tiny blurred preview code for websites. | 3 | +| Palette | Extracts the main colours as JSON or CSS variables. | 3 | +| Contact sheet | Combines many images into one grid image. | 3 | +| Images to PDF | Combines images into one PDF. | 3 | + +## Saving and sharing pipelines + +- Clicking Save stores the pipeline in the browser. The save dialog always shows one line: "Saved in + this browser only. Clearing site data deletes it; export a .hexlode file to keep a backup." +- Nothing is stored in the browser until the user clicks Save or starts a run. +- A pipeline exports to and imports from a `.hexlode` file. The file is versioned JSON, and older + versions are migrated on import. + +## Analytics + +Analytics are always on and store nothing in the browser, so the app needs no cookie banner. +Hexlode records detailed product events: runs, image counts, successes, skips, failures with reasons, +timings, the quick tools used, and the shape and settings of pipelines. Analytics never include +file names, paths, pixels, image metadata or text the user types. The app has a short privacy page +that lists what it collects. + +## Cloud (after version 1) + +A signed-in cloud mode may later run large jobs on a server, keep running after the browser closes, +and use a credit system. Local processing stays free and unlimited. The database and account code +in the repository waits for this work. + +## Out of scope for version 1 + +- Accounts, sign-in, cloud processing and billing. +- HEIC input, animated images and colour-profile conversion. +- Dither and retro effects. +- The Studio on phones. diff --git a/implementation.md b/implementation.md index f0fd30f..ee2a6b7 100644 --- a/implementation.md +++ b/implementation.md @@ -1,414 +1,155 @@ -# Hexlode — Implementation Plan - -> Status: Working execution plan -> Updated: 2026-08-04 -> Product direction: [idea.md](./idea.md) - -## 1.

Record baseline processing time and peak-risk memory assumptions for representative images. - -### Not included - -- A worker pool. -- Multiple output codecs. -- Graph branching. -- Accounts or database writes. -- Offline installation. -- SDK, CLI, or package extraction. -- WebGPU, custom native codecs, or cloud processing. +## Goal -### Exit gate - -- A valid JPEG and PNG complete the pipeline. -- The interface remains responsive during processing. -- Cancellation stops work and releases retained references. -- Malformed and oversized input returns a controlled error. -- The output downloads and opens correctly. -- `pnpm validate` passes. +Version 1 is the complete local product: the home page, four quick tools, pipeline tools, and the +Studio with all 33 nodes from the catalogue in [idea.md](./idea.md). It ships in three phases. Phase 1 +builds the whole application and node batch 1. Phases 2 and 3 only add node batches 2 and 3. Each +phase is deployable and passes its exit gate before the next phase starts. -## 8. Milestone 2 — Editable Canvas +Active phase: **Phase 1**. -### Outcome +## Phase 1: the application and node batch 1 -Run the proven processing slice from the real starter graph: +### Cleanup -```text -Files -> Inspect -> Resize -> WebP -> Compare -> Download -``` +1. Remove the old canvas UI, recipe dialog, privacy modes (Private Session and Airgap), Codec + Tournament, macro presets and debugger. +2. Keep code that fits the new engine: input validation, the worker message protocol, the serial + batch queue and streaming ZIP output. Move each piece into the new layout when the engine + needs it. +3. Remove the MCP demo (`src/routes/mcp.ts`, `src/mcp-todos.ts`, `src/utils/mcp-handler.ts`). +4. Keep Drizzle and Better Auth compiling and unused + ([ADR 0006](./docs/adr/0006-dormant-database-and-accounts.md)). -### Work +### Foundation -1. Create the `canvas` feature and render React Flow inside an Astryx application shell. -2. Define only the ports and node types used by the starter graph. -3. Build reusable node chrome for label, state, handles, and concise settings. -4. Keep detailed settings in an inspector panel. -5. Reject incompatible connections with a useful message. -6. Compile the visible graph into the Milestone 1 operation sequence. -7. Stream worker progress and errors into node and edge state. -8. Add run, cancel, retry, add, delete, connect, and reconnect behavior. -9. Add undo and redo after graph editing is stable. -10. Add keyboard access for the essential starter workflow. -11. Store result references outside React component state. +5. Replace `node:test` with Vitest, with browser mode on Playwright Chromium for worker, OPFS and + codec tests. +6. Set up PostHog and Sentry as described in Analytics below, and add the privacy page. +7. Add a Dockerfile and deploy on Dokploy. The image builds with the public `VITE_POSTHOG_KEY`, + `VITE_POSTHOG_HOST` and `VITE_SENTRY_DSN` as build arguments. -### Exit gate +### Engine -- A first-time user can drop an image and run the starter graph unchanged. -- Editing a supported node changes the real execution. -- Invalid connections cannot enter a saved graph. -- Canvas state and worker execution state remain separate. -- Progress and errors shown by the UI come from the worker. +8.

Milestone 4 — Batch and Production Workflows - -### Outcome - -Process useful folders without uncontrolled memory growth. - -### Work - -1. Add `ImageBatch` only after single-image execution is stable. -2. Implement a bounded queue before adding parallel workers. -3. Choose concurrency using estimated memory and device capability. -4. Report per-file progress and collect failures without losing successful results. -5. Add folder input with browser capability fallbacks. -6. Add deterministic rename templates and collision handling. -7. Preserve relative hierarchy where supported. -8. Add ZIP output and selected-folder output where the browser permits it. -9. Add JPEG and PNG output; add AVIF after adapter and fixture validation. -10. Add orientation correction, transparency policy, and selective metadata removal. -11. Add retry-failed, continue-on-error, and cancel-queued behavior. - -### Exit gate - -- A representative large batch completes within a bounded memory policy. -- A corrupt file does not discard successful items. -- Cancellation stops queued work and cleans temporary references. -- Naming collisions are deterministic and recoverable. -- Metadata and transparency changes cannot occur silently. - -## 11. Milestone 5 — Signature Features - -Implement these one at a time after the underlying measurements and adapters are reliable. - -### Codec Tournament - -- Compare supported encoders and selected settings against the same input. -- Show size, time, quality, transparency, and compatibility. -- Reuse the existing adapters rather than adding a second execution path. - -### Constraint Solver - -- Start with a bounded quality search for one codec. -- Add hard work, time, and memory limits. -- Make it cancellable and deterministic for the same engine version. -- Explain when no valid result exists. - -### Visual Difference Lab - -- Begin with side-by-side and slider comparison. -- Add synchronized zoom, heatmap, and perceptual metrics only when correctness is verified. - -### Macros and debugger - -- Support a local reusable subgraph before nested or shared macro versions. -- Show runtime data emitted by the engine rather than UI-derived guesses. - -## 12. Milestone 6 — Optional Accounts and Cloud Processing - -This milestone begins only after anonymous local usage demonstrates the need. - -### Recipe synchronization - -1. Connect Better Auth to PostgreSQL only when account-backed sync is being implemented. -2. Synchronize recipes, macros, preferences, and versions—not images or metadata. -3. Require explicit opt-in before migrating local recipes to an account. -4. Keep sign-out and offline behavior usable. -5. Provide export and deletion for synchronized data. - -### Cloud batches - -1. Identify a measured workload that local execution cannot serve well. -2. Define the job boundary, quota, retention, deletion, and failure policy first. -3. Show exactly what leaves the device before each remote job. -4. Require explicit consent and make local versus remote execution visible. -5. Add idempotency, cancellation, timeouts, and cleanup before charging or broad access. -6. Offer a generous free allowance and recover costs gradually only when required. - -Do not build billing, queues, object storage, or worker infrastructure in anticipation of demand. - -## 13. Experimental Backlog - -Possible later experiments: - -- Background removal and upscaling. -- OCR and sensitive-information redaction. -- Smart crop and local ML inference. -- GPU-accelerated transforms with CPU fallback. -- Duplicate and similarity detection. -- Dithering, palette, and unusual-codec labs. -- Public recipe sharing. - -Each experiment needs a clear local or remote label, bounded resource use, and measurable value. - -## 14. Testing Strategy - -Keep tests proportional to current risk. - -### Add with Milestone 1 - -- Focused unit tests for graph-independent validation and planning logic. -- Worker-protocol and cancellation tests. -- Small licensed or generated JPEG and PNG fixtures. -- Manual development and production-build smoke checks. - -### Add when formats and batches expand - -- Fixture-based regression tests for orientation, transparency, metadata, and malformed input. -- Deterministic output assertions where the adapter guarantees determinism. -- Perceptual thresholds where binary equality is not meaningful. -- Memory, queue, cancellation, and cache-policy tests. - -### Deferred - -- Playwright or another browser automation suite. -- Large cross-browser matrices. -- Property testing and benchmark infrastructure. -- Visual-regression platforms. - -Revisit browser automation when a critical file API, offline path, or browser-specific regression -cannot be covered reliably by unit tests and manual release checks. - -## 15. CI for the Public Repository - -Start with one GitHub Actions workflow: - -1. Use the Node version from `.nvmrc`. -2. Install pnpm and run `pnpm install --frozen-lockfile`. -3. Run `pnpm check`, `pnpm typecheck`, and `pnpm build` through `pnpm validate`. - -Add dependency review, CodeQL, release automation, fixture matrices, or scheduled security checks when -the repository is public and those workflows have a concrete input to inspect. Free CI capacity is -welcome, but each workflow should still have a useful signal and a clear owner. - -## 16. Security and Privacy Guardrails - -- Treat every image as untrusted input. -- Check signatures, dimensions, and predicted allocations before decode. -- Bound worker count, search attempts, and batch memory. -- Never place file bytes, names, metadata, thumbnails, or linked hashes in analytics. -- Keep cloud processing disabled unless the user explicitly selects it. -- Do not retain source bytes or intermediates without an intentional local setting. -- Track security and licensing status for every codec dependency. -- Fail safely when a browser lacks a required capability. - -These guardrails are part of the feature definition, not optional hardening work. - -## 17. Decision Triggers - -### Create a package or monorepo only when - -- A second independently shipped application, CLI, or service must consume the same code. -- Sharing source inside this repository is no longer practical. -- The boundary has a stable API and an owner. - -### Build a custom processing implementation only when - -- Existing libraries cannot meet a documented requirement. -- A benchmark or correctness test demonstrates the benefit. -- Security, licensing, fixtures, and long-term maintenance are understood. - -### Build cloud processing only when - -- Real jobs exceed reasonable local time or memory. -- Users explicitly request the capability. -- Cost, abuse, retention, deletion, and incident policies are decided. - -### Add browser automation only when - -- A critical browser behavior has regressed or cannot be verified cheaply another way. - -## 18. Immediate Next Target - -Implement Milestone 1 only: - -```text -Choose JPEG or PNG - -> validate - -> decode in a worker - -> resize - -> encode WebP - -> preview and compare - -> download -``` - -Do not scaffold later feature folders or build a polished node catalogue around fake execution. - -## 19. Definition of Success - -Implementation is on track when: - -- The local product is useful without an account or backend. -- The canvas represents real execution rather than simulated progress. -- Feature modules keep the single application understandable. -- Large work is bounded, cancellable, and recoverable. -- Privacy boundaries match what the interface promises. -- New infrastructure is added in response to measured need rather than imagined reuse. - -Preserve the product loop: - -> Drop -> experiment visually -> compare -> save -> reuse. +- The app starts from a fresh clone with no `.env.local`. +- Every quick tool and template runs on real JPEG, PNG, WebP, AVIF, JPEG XL and QOI fixtures. +- A batch of 500 generated 12-megapixel images completes without memory growing with batch size. +- Changing a node's setting and running again executes only that node and the nodes after it. +- A `.hexlode` file round-trips without changes. +- The node pair matrix passes (see Testing). +- `pnpm validate` passes and the app runs in the Docker image. + +## Phase 2: node batch 2 + +Auto-trim, Pad / Extend, Pixel-art upscale, Split / Tile, Adjust, Filters, Sharpen / Blur, +Background, Text watermark, Image watermark, Border / Rounded corners, Deduplicate. Adds the +Watermark and compress and Instagram carousel templates. + +Exit gate: each node has output tests on real fixtures, the node pair matrix passes with the new +nodes, and the new templates run end to end. + +## Phase 3: node batch 3 + +Best format, Responsive set, Favicon / App icons, Placeholder, Palette, Contact sheet, Images to +PDF, Set copyright / author. Adds the Responsive image set template. + +Exit gate: same as phase 2, plus tests for nodes that change the item count (one image to many, +many images to one) and nodes that produce data or documents. + +## Engine design + +- A pipeline is a directed graph without cycles. Items flow through it one by one, so an item can + reach the last node while later items are still at the first node. +- Nodes that combine items (Contact sheet, Images to PDF, near-duplicate Deduplicate) wait until + every upstream item has arrived. +- Decoding happens at most once per item, the first time a node needs pixels; nodes that only read + headers or metadata (Filter by format, Inspect, Rename, Strip metadata) never decode. Nodes pass + pixels between them. Encoding happens at Convert, Compress to size and Optimize PNG. An image + that reaches Output without an encoding node keeps its source format, and its original bytes + when nothing changed its pixels. +- Metadata is rewritten in the container without re-encoding for JPEG, PNG, WebP and JPEG XL. + AVIF metadata is read and can be removed in place but not added; QOI holds none. The run reports + a warning when a format cannot keep metadata. +- Each source item travels through the whole pipeline inside one worker, so pixels never cross + threads. The pool admits as many items as it has workers, which bounds memory by pool size, not + batch size. Combining nodes spill their inputs to OPFS and run after everything upstream is done. +- Items carry their metadata. Encoders write it back where the format supports it. Strip metadata is + the only node that removes metadata; when an encoder cannot keep metadata, the run reports a + warning. +- A worker pool runs the tasks. The pool size depends on CPU cores and the memory estimate of the + largest item in flight. +- An item a node cannot accept skips that branch + ([ADR 0003](./docs/adr/0003-items-skip-branches-they-cannot-enter.md)). +- The step cache stores each node's last results in OPFS, keeping the encoded form of an item + instead of its pixels when both exist. Nodes that only change metadata or names store a reference + to their input instead of a copy. The cache key combines the node's settings + and the cache keys of its inputs, so a settings change invalidates that node and every node after + it ([ADR 0004](./docs/adr/0004-opfs-for-outputs-and-step-cache.md)). +- The step cache has a 5 GB budget by default, which the user can change in settings. When it is + full, the least recently used results are deleted. A node whose results were deleted runs again + from the nearest earlier node that still has a step cache, and the estimate includes that work. +- The engine is plain TypeScript with no React. The UI subscribes to engine events. + +## Testing + +We write tests first, using the `tdd` skill. A test must fail when the behaviour it covers is +removed. + +- Node tests decode the file the node produces and check format, dimensions, sample pixel values + and metadata. +- Fixtures are small files in the repository, generated or with a licence that allows it, covering + every input format, transparency, EXIF orientation, location metadata and a malformed file. +- The node pair matrix connects every pair of node types and checks that the Studio's accept or + refuse decision matches what the engine does when it runs that pair. +- Worker, OPFS, codec and ZIP tests run in real Chromium through Vitest browser mode. Locally they + use `PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH`; CI installs Chromium with Playwright. +- Test-only node types with data and document items, one-to-many and many-to-one behaviour prove + what batches 2 and 3 need. They join the node pair matrix but never the product registry. +- The batch of 500 images of 12 megapixels runs with `pnpm test:scale`. It takes minutes, so it is + outside `pnpm validate`; run it before closing a phase. +- `pnpm validate` passes before every commit. + +## Analytics + +- PostHog uses `cookieless_mode: 'always'` and `person_profiles: 'never'`, with IP capture, session + replay and autocapture turned off. The app sends its own events from one analytics module + ([ADR 0005](./docs/adr/0005-cookieless-explicit-analytics.md)). +- Sentry sends errors with `sendDefaultPii: false` and no replay. File names are removed from error + messages before sending. +- The PostHog project must have cookieless mode enabled and "Discard client IP data" turned on; + without the first, PostHog ignores cookieless events. The client also clears `$ip` on every event. +- The event catalogue lives in `src/features/analytics/events.ts`, and the privacy page lists it. + +## Deployment + +The app runs as one Docker container that serves the Nitro build. Dokploy on the maintainer's VPS +builds the Dockerfile and handles the domain and HTTPS. A future cloud mode adds a Postgres +container next to it. diff --git a/instrument.server.mjs b/instrument.server.mjs index 98695b2..c6bf4b5 100644 --- a/instrument.server.mjs +++ b/instrument.server.mjs @@ -2,15 +2,14 @@ import * as Sentry from '@sentry/tanstackstart-react' const sentryDsn = import.meta.env?.VITE_SENTRY_DSN ?? process.env.VITE_SENTRY_DSN -if (!sentryDsn) { - console.warn('VITE_SENTRY_DSN is not defined.
