Changelog

All notable changes to the hutfx project are documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

How to use this file:

• For every change, add a bullet under ## [Unreleased] in the same commit.
• Use the sections Added, Changed, Deprecated, Removed, Fixed, Security.
• On release: give the section a version number and date, bump the version, and open a fresh [Unreleased] block.
• Never rewrite an already-released entry — add a new one instead.

Unreleased

Added

• meetings/: daily raw work log (one dated file per working session). First entry 2026-11-01.md. Standing rule added to the home page: NEO documents work into categories + writes the daily meeting log proactively.

Changed

• Wiki restructure (2026-11-01, NEO): docs reorganized into web/ (website/service plans), technical/ (servers, network, domains, sysadmin), development/ (workflow, stack, snippets, house rules); plans/ dissolved. Home page index.md explains every directory; each directory got an index.md. Rendered wiki now live at http://doc.hutfx.com/ (rebuild via /home/sato/bin/build-wiki, raw sources under /raw/).

Added

• doc/plans/2026-11-01-dev-environments.md: accepted plan for the per-user dev environments (design + implementation record).
• doc/development-workflow.md: permanent team workflow — branch model (main / active_work / feature branches + PRs), per-user dev environments on hut, daily loop, team mail list, credentials policy. Adopted 2026-11-01.

Added

• doc/ folder as the documentation home: changelogs, plans, and project files (all in Markdown). Includes plans/TEMPLATE.md and projects/TEMPLATE.md.
• Public documentation browser at /doc (dark theme, matches the landing page): sidebar lists every Markdown file under doc/ and renders the selected file server-side (CommonMark + GFM: tables, task lists, strikethrough; raw HTML is escaped). Path traversal and non-Markdown files are rejected with 404. In the page header the hutfx logo/wordmark is the link back home (no separate "Home" menu item).
• league/commonmark promoted to a direct dependency for the Markdown rendering.
• Mermaid diagram support in the /doc browser: ```mermaid fenced blocks in any doc file are drawn client-side (mermaid.js, dark theme, loaded only on /doc pages). Documented in doc/README.md; first demo diagram in plans/2026-08-16-product-vision.md.
• The /doc sidebar is now collapsible: a hamburger toggle above the content opens/closes the file list (collapsed by default so the main content uses the full width; the choice is remembered per browser via localStorage).
• The dashboard now has a "Linear function" section: a Chart.js line chart of y = 2x + 3 for x = 1..10 (dark theme, tooltips on hover), rendered client-side from a dedicated resources/js/dashboard.js Vite entry.
• The hutfx wordmark's last two letters now read as the math function f(x) in a LaTeX-style math font (self-hosted STIX Two Text — italic f and x, upright parentheses), applied to every brand sign: landing header
• hero, dashboard nav, docs header, and the login/register page title.
• Product planning documents (drafts, awaiting owner review): projects/hutfx.md — platform goal, proposed scope, and milestone roadmap; plans/2026-08-16-product-vision.md — proposed functionalities & services with open questions. Both browsable at /doc.
• plans/2026-08-17-pipelineengine.md — working description of the Pipeline Engine (website spec section 3, "Model Builder"): the reusable pipeline tool — choose a dataset, process it through modules on an infinite dot canvas (clean / calculate / graph / Python sandbox / IF-else blocks), view the result, then save it as a module (composable into other pipelines), a research record, or export it to other services (ML/LLM, device signal, …). Draft, being described with the owner; linked from the website spec (section 3) and projects/hutfx.md.
• The Pipeline Engine description (plans/2026-08-17-pipelineengine.md) now folds in the owner's locked section 3 description from the website spec: the four data-loading paths (select / upload / live source / Data Router), predefined pipeline templates vs. a blank canvas, user-defined custom modules, visual sliders for params and hyperparams, natural-language instructions converted to code + config files, modules as backend config files (direct edit for advanced users), sandbox languages (Python, R, Julia), results feeding the Research dashboard for comparing iterations, and modules sold on the Market. A new "Naming & terminology" section records the owner's preferred name ("pipeline builder"), the "architect" / "constructor" wording, and the nested-canvas concept for training / quantum-algorithm modules. Open questions already answered by the section 3 description are marked as answered in the doc.
• The Pipeline Engine doc now records a proposed canvas approach: Svelte Flow (@xyflow/svelte 1.6.3 — the official Svelte port of React Flow by the xyflow team; Svelte 5, MIT): dot-grid background, handles, minimap/controls built in, and subflows out of the box (matching the owner's nested-canvas note). Pattern: Svelte as a widget runtime mounted from Blade via a dedicated Vite entry — stack impact and trade-offs are documented in the plan. Awaiting owner confirmation; the description is not fully locked yet.

Changed

• Wordmark overlap fix: removed the -0.1em margin that pulled 𝑓 into the t — at the hero's size (60px) the collision was clearly visible. The two fonts' natural metrics (t right bearing 0.027em + 𝑓 left bearing 0.01em) already produce a tight gap, so hut𝑓(𝑥) now renders with the same tight spacing at every size, no overlap.
• Wordmark math tail refinements: the gap between hut and the math part is tightened (negative margin offsets the math glyph's wide side bearing), the parentheses are back — it reads 𝑓(𝑥) — and the math part now renders unbolded (weight 400, no faux-bold) and slightly larger (1.1em) than hut. The STIX Two Math subset now also includes the parentheses glyphs.
• The wordmark math tail now uses true Unicode Mathematical Italic glyphs — 𝑓 (U+1D453) and 𝑥 (U+1D465) — instead of synthesized italics, and the parentheses are gone (the tail reads 𝑓𝑥). Self-hosted STIX Two Text was replaced by a subset of STIX Two Math (public/fonts/stix-two-math-math.woff2, the Mathematical Alphanumerics block U+1D400–U+1D7FF only), with Noto Serif Math/Cambria Math as system fallbacks.
• Changelog now lives at doc/CHANGELOG.md (moved out of the repository root).
• Authenticated navigation: the logo/wordmark now links to the landing page (home), and the redundant "Dashboard" nav link (desktop + mobile menus) was removed from the dashboard.
• The logged-in user's name is now shown in the header on every page (landing, /doc, dashboard). It opens a dropdown containing the Dashboard, Profile, and Log Out actions — the standalone "Dashboard" button on the landing and doc pages moved into that dropdown.

Fixed

• API routes (routes/api.php) were never registered in bootstrap/app.php, so GET /api/v0/health and POST /api/v0/telemetry always returned 404 — now registered under the /api prefix.
• HealthApiTest requested /apiv0/health (missing slash) and could never match the real route — now asserts against /api/v0/health.

0.2.0 - 2026-08-15

Added

• Authentication: registration, login with "remember me", Google OAuth sign-in, forgot/reset password, email verification, password confirmation.
• Dashboard page for signed-in users.
• Profile page: update name/email, change password, delete account (confirmation modal).
• Auth controllers, requests, routes, and Blade views (login, register, forgot/reset password, verify email, confirm password, dashboard, profile).
• Dark theme across all pages, matching the landing page: app & guest layouts, navigation bar, all auth pages, profile pages, and shared components (inputs, labels, buttons, dropdowns, nav links, modal).
• README.md with project overview, install instructions, and database recreation guide.
• CHANGELOG.md for tracking what is new or changed with every commit.

Changed

• Replaced the default light Breeze theme with the dark palette (#0a0a0a background, #EDEDEC text, #3E3E3A borders, #141414 cards).
• Primary buttons are now light (#EDEDEC) with dark text, matching the landing page.
• README replaced the Laravel boilerplate with hutfx-specific documentation.
• .gitignore now ignores *.bak backup files.

0.1.0 - 2026-08-04

Added

• Initial Laravel 13 application scaffold (PHP 8.3, Tailwind CSS, Alpine.js, Vite).
• Dark-themed public landing page at /.
• Telemetry API v0: GET /api/v0/health and POST /api/v0/telemetry (stores device, collected data, unit of measure) + Telemetry model.
• PostgreSQL migrations: users/password_reset_tokens/sessions, cache/cache_locks, jobs/job_batches/failed_jobs, telemetries.
• Database-driven session, cache, and queue configuration.
• Feature and unit test suites (HealthApiTest, HomePageTest, profile/auth tests).
