History before 0.1.0 ​

The project restarted on 2026-10-13 from one consolidated commit, version 0.1.0. During its first epic the documentation grew as a working record — every exchange, every attempt, in great detail; at the end of E01 it was rewritten into the reference it is meant to be, and the repository was started again from that clean base. This page keeps the record of what came before: every commit's message and the files it touched, without their content.

  • chore(tooling): bootstrap strict tooling, documentation site and backlog Initial state of the project before any library code (src/ is an empty barrel). - ESLint 10: every rule of every plugin decided once, in small per-theme files, with a completeness audit test; custom rules for function kinds, one export per file, folder barrels, canonical import paths and verified @see references. - TypeScript 6 (strict), Prettier + EditorConfig, Vitest, Vite library build and playground; npm audit and latest-version checks block the pipeline. - Git workflow: Conventional Commits (commitlint), branch names, husky hooks. - Documentation in English: domain, ADR-0001 to ADR-0017, conventions, tooling, research protocol, bibliography; VitePress site with TypeDoc API pages. - Agile backlog in the repository (epic, feature, story, task, no iterations), with eight draft epics awaiting the Product Owner's review. Refs: ADR-0009, ADR-0010, ADR-0011, ADR-0012, ADR-0013, ADR-0014, ADR-0015, ADR-0016; Refs: ADR-0017, Q10, Q11 Files: .editorconfig, .github/workflows/ci.yml, .gitignore, .husky/commit-msg, .husky/pre-commit, .husky/pre-push, .idea/.gitignore, .idea/SVG editor.iml, .idea/inspectionProfiles/Project_Default.xml, .idea/jsLinters/eslint.xml, .idea/modules.xml, .idea/prettier.xml and 215 more.
  • ci: add GitHub quality gate, security scans and automated releases
    • CI on pull requests and main: check:all (format, lint, secrets, types, tests, audit, latest versions, docs build), build, commitlint on every commit, branch name, dependency review. - CodeQL security and quality analysis; secretlint before commit and in CI. - release-please for versions and CHANGELOG from Conventional Commits. - Dependabot weekly updates, pull request template. - Workflow: one branch per story, one commit per task, rebase merge.

  • build(eslint): lint Markdown structure with @eslint/markdown
    • @eslint/markdown checks headings, links, code languages, bare URLs and tables of every page; its rules are decided in eslint/rules/markdown and audited. - markdownlint-cli2 and Stylelint are not installed: they depend on braces, vulnerable without fix (GHSA-vfj7-8cjw-p6xm); recorded in the docs. - katex forced to 0.19 (GHSA-238p-pmpm-9mq7); overrides checked by test.

  • docs(backlog): rewrite epics from the product vision and plan F01
    • Domain: four tools (Symbol Editor, Configurator, View Editor, drawing tools), configuration trees, interfaces, property groups, business types and libraries, animations, static drawings, free shape rotation in symbols. - Settled Q5 (local server), Q10 (5 decimals, EPSILON 1e-9), Q11 (clockwise from the top-left vertex, cyclic contours); opened Q12, Q13, Q14. - Eleven draft epics in the Product Owner's order; E01 split into features; F01 split into eleven stories with tasks. - File names and titles carry the ancestry (E01-F01-US-001); backlog test checks prefixes and YAML quoting.

  • docs(adr): allow Bézier curves in static drawings and settle Q12 to Q15
    • ADR-0018: Figma-like Bézier pen in static drawings only; symbols keep ADR-0001. - Q13: animations remap a property range to their own range. - Q14: a configuration node brings its own and its ancestors' options; sub-trees of other trees can be added. - Q15: rectangle sizes are >= 0; US-001 and EN-001 criteria updated. - Stylelint postponed until SCSS starts (braces advisory); GitHub settings written step by step in docs/tooling/ci.md.

  • build(eslint): require kebab-case file names named after the export
    • local/one-export-per-file now expects the kebab-case of the export (formatSvgNumber -> format-svg-number.ts); unicorn/filename-case applies kebab-case everywhere again; SVG_DECIMALS.ts renamed svg-decimals.ts. ADR-0019 supersedes ADR-0015. - jsdoc/informative-docs ignores @kind, a classification that may repeat the function name (format on formatSvgNumber).

  • feat(io): add formatSvgNumber for fixed-precision output Rounds to SVG_DECIMALS decimals and writes the shortest form: no trailing zeros, no negative zero. Tests were written first (cases computed by hand) and committed with the implementation, as the pre-commit hook requires a compiling tree. Refs: EN-001.T1, EN-001.T3, Q10 Files: src/io/format-svg-number.test.ts, src/io/format-svg-number.ts.
  • docs(backlog): record EN-001 output rules and tick its tasks The shortest-form rules (no trailing zeros, no negative zero) accepted by the Product Owner join Q10 in docs/domain/shapes.md. EN-001 stays in-progress until the Product Owner accepts it by merging the pull request.

  • build(deps): bump vite from 8.3.3 to 8.3.4 Refs: ADR-0009 Files: package-lock.json, package.json.
  • ci: fix the release pull request and publish the docs site on release
    • CHANGELOG.md is generated by release-please: excluded from Prettier and secretlint (it failed format:check on the release pull request). - First version is 0.1.0 (initial-version) instead of release-please's 1.0.0. - After a release, the docs job builds VitePress + TypeDoc and deploys it to GitHub Pages (also runnable by hand); the site base path comes from DOCS_BASE.

  • build(tooling): require full coverage and add standard repository files
    • Vitest coverage (v8) with 100 % thresholds on src/, run by npm test. - Node version pinned in .nvmrc (CI reads it) and enforced by engine-strict. - SECURITY.md with private vulnerability reporting (enabled on GitHub). - README: CI, CodeQL and release badges, link to the documentation site. - Docs and CLAUDE.md: post-merge routine, release pull request CI, lessons learned from EN-001.

  • docs(tooling): list the tools considered for later knip, size-limit, api-extractor and Stryker, with what they would bring and when. Refs: ADR-0009 Files: docs/tooling/dependencies.md, package.test.ts.
  • chore: license the project under Apache-2.0 Official text from apache.org; NOTICE holds the copyright line. package.json declares the license, repository and homepage; LICENSE and NOTICE ship with the package. Files: LICENSE, NOTICE, README.md, package.json.
  • ci: run release-please with a token and rename to synoptic-studio
    • release-please uses RELEASE_PLEASE_TOKEN, so the CI runs on its pull requests (token expires 2026-12-31). - The repository is now github.com/AlexandreGallais/synoptic-studio: links, README, CLAUDE.md and docs updated; the Pages base path follows the name. Refs: ADR-0009 Files: .github/workflows/release.yml, CLAUDE.md, docs/.vitepress/config.ts, docs/tooling/releases.md.

  • feat(math): add the Point type Point of the plane in SVG user units; integer in the model, float in derived geometry (ADR-0003). Refs: US-001.T2, US-001.T4 Files: src/index.ts, src/math/index.ts, src/math/point.ts.
  • feat(model): add the rectangle contour and its validation
    • Rectangle: integer width and height, >= 0. - rectangleContour: four vertices clockwise on screen from the top-left one (Q11), integer coordinates (ADR-0003), degenerate sizes allowed (Q15). - isValidRectangle: rejects negative or fractional sizes (Q15, ADR-0003). Tests were written first (cases computed by hand) and committed with the implementation, as the pre-commit hook requires a compiling tree.

  • fix(model): document type members and catch it before the docs build
    • Point and Rectangle properties are documented: TypeDoc failed the docs build of the pull request on undocumented properties. - jsdoc/require-jsdoc now covers type members in src/, so lint reports it. - The pre-push hook runs check:all (docs build included).

Refs: ADR-0009 Files: .github/workflows/release.yml, CLAUDE.md, docs/tooling/releases.md.
  • chore(main): release 0.2.1 Files: .release-please-manifest.json, CHANGELOG.md, package-lock.json, package.json.
  • docs(backlog): set stories done in their pull request Merging a story's pull request is the Product Owner's acceptance, so the story is set to done in the pull request's last commit: main never needs a status commit after a merge. A test now checks that the folder indexes show the status written in each item file. Refs: ADR-0017 Files: CLAUDE.md, backlog.test.ts, docs/backlog/README.md.
  • chore(main): release 0.2.2 Files: .release-please-manifest.json, CHANGELOG.md, package-lock.json, package.json.
  • test(backlog): check the epics index and require every item to be listed The status check skipped the epics index: its rows start with an order column the pattern did not allow, so no epic was compared. The pattern now finds the item link anywhere in the row, and a new test requires every item to appear in its folder index, so a row can no longer be skipped silently. Each index was mutation-checked (a wrong status makes the test fail). Refs: ADR-0017 Files: backlog.test.ts.
  • docs(backlog): set EN-002 ready Product Owner agreement given in the session of 2026-10-08. Refs: EN-002 Files: docs/backlog/stories/E01-F01-EN-002-sharp-contour-path-data.md, docs/backlog/stories/README.md.
  • feat(io): write the path data of a sharp contour contourToPathData writes M for the first vertex, L for the others and Z, numbers through formatSvgNumber (EN-001); an empty contour gives an empty d. Tests were written first (cases computed by hand) and committed with the implementation, as the pre-commit hook requires a compiling tree.

  • ci: publish the playground with the docs site
    • vite build --mode playground builds the playground into the docs site (docs/.vitepress/dist/playground); the default mode still builds the library. - The release workflow publishes it on GitHub Pages next to the docs, with a Playground link in the docs menu; check:all builds it so a broken playground fails the CI.

  • feat(render): create SVG canvas and path elements
    • createSvgElement: <svg> in the SVG namespace with a viewBox written at fixed precision; createPathElement: <path> with its d attribute. - ViewBox type and SVG_NAMESPACE constant (REF-MDN-CREATEELEMENTNS). - happy-dom runs the render tests, keeping 100 % coverage of src/.

  • feat(playground): draw a sharp rectangle from typed width and height The playground draws the rectangle as one <path> through the public API (model, contour, path data, render) and shows each pipeline stage. Sizes that are not integers >= 0 are refused: inputs outlined, message shown, drawing unchanged. "read" joins the procedure verbs. Checked by a throwaway happy-dom run of the real page: 120 x 80 drawn, 10.5 refused, 200 redrawn, a single <path>. Refs: US-002.T2 Files: eslint/settings/verbs.ts, playground/index.html, playground/index.ts.

  • feat(playground): draw shapes at a fixed scale The view box takes the size of the drawing area in CSS pixels, so one user unit is one pixel: a rectangle twice as large is drawn twice as large. The canvas fills the page height and cuts shapes larger than itself. Refs: US-004.T1 Files: playground/index.html, playground/index.ts.
  • feat(playground): keep the scale when the window is resized The playground redraws on window resize: the view box follows the new size of the drawing area, shapes keep their size on screen. Checked by a throwaway happy-dom run with a simulated 800 x 600 then 400 x 300 canvas. Refs: US-004.T2 Files: playground/index.ts.

Refs: EN-003.T1, Q11 Files: docs/derivations/README.md, docs/derivations/turning-angle.md, docs/references.md.
  • feat(math): add vector subtraction, dot and perp dot products
    • Vector type; subtract (REF-MATHWORLD-VECTOR-DIFFERENCE), dot (REF-MATHWORLD-DOT) and perpDot, the 2D cross product (REF-MATHWORLD-PERP-DOT), one file each. - The root barrel re-exports math as values now that it holds functions.

  • test(tooling): fail when a barrel re-exports values as types only The barrel autofix writes export type * for a type-only folder and never switches back once the folder holds values: the root barrel hid the math functions. barrels.test.ts loads every module re-exported as types only and fails if it exports a runtime value (mutation-checked on the old barrel). Refs: EN-003 Files: CLAUDE.md, barrels.test.ts.
  • feat(geometry): compute the turning angle at each contour vertex
    • turningAngle: tau = atan2(perp dot, dot) of the incoming and outgoing edges (DERIV-turning-angle); positive for a clockwise turn on screen. - turningAngles: one angle per vertex of a cyclic contour (Q11). - cyclicVertex: vertex at index mod n, with an explicit fallback for an empty contour (a reachable branch, so coverage stays at 100 %). Tests follow the derivation's check table and were written first.

  • docs(adr): open every feature with research and close it with an audit ADR-0020: a research spike (SP) sources all the feature's stories before any code; an audit (AUD) re-derives the mathematics, recomputes expected values, mutation-checks each function, re-verifies the sources, checks provenance, duplicates and consistency; then the Product Owner validates (VAL). Regression and end-to-end tests come with the applications.

  • docs(backlog): frame features with research, audit and validation Feature frame and AUD story type in the method, spike and audit templates, F01 receives SP-001 (research for its remaining stories) and AUD-001. The backlog test fails when a feature lacks its spike, audit or validation (mutation-checked).

  • docs: reorganize CLAUDE.md and fix stale statements CLAUDE.md follows the order of use (where to read, rules, feature and story lifecycles, definition of done, guardrails, pitfalls), states the current state instead of "src/ is empty", and links to the domain for settled questions. Stale statements fixed in conventions, commands, lint zones; the docs home links to the backlog and the playground. Refs: ADR-0020 Files: CLAUDE.md, docs/conventions/architecture.md, docs/conventions/lint.md, docs/index.md, docs/tooling/commands.md.
  • chore(main): release 0.6.1 Files: .release-please-manifest.json, CHANGELOG.md, package-lock.json, package.json.
  • docs: record agent and verification practices Research note 0002: Claude Code documentation (best practices, memory, skills, hooks, subagents), context engineering, spec-driven development critiques, QuickCheck and fast-check, mutation testing at Google and the StrykerJS trial (blocked by stryker-js issue 6210 with Vitest 5), lychee trial. Thirteen references recorded, each read on 2026-10-08. Refs: ADR-0021, ADR-0022 Files: docs/references.md, docs/research/notes/0002-agent-and-verification-practices.md, docs/research/notes/README.md.
  • docs(adr): adopt an agent working environment and property-based tests ADR-0021: rules true everywhere stay in CLAUDE.md; procedures become skills, area pitfalls become path-scoped rules, an independent read-only auditor reviews each feature, hooks guard merges and Git hook bypasses and reload the project state at session start. ADR-0022: fast-check properties next to the hand-computed examples, weekly lychee link check, StrykerJS deferred. ADR-0020: date corrected to 2026-10-08.

  • build(deps): add fast-check for property-based tests fast-check 4.10.2 and @fast-check/vitest 0.5.0, pinned, audit clean. Testing conventions describe properties (record form, seeds, Object.is and -0). StrykerJS stays under "considered for later" until stryker-js issue 6210 is fixed. Refs: ADR-0022 Files: docs/conventions/testing.md, docs/tooling/dependencies.md, package-lock.json, package.json.
  • ci: check every Markdown link weekly with lychee links.yml runs lychee-action v2 every Monday and on demand, over all Markdown including .claude/, templates excluded; local trial: 225 links OK. Refs: ADR-0022 Files: .github/workflows/links.yml, .lycheeignore, docs/tooling/ci.md.
  • chore(tooling): configure the agent with skills, rules, auditor and hooks Skills story, spike, derivation, audit; path-scoped rules for the library, Markdown and tooling; read-only auditor subagent; settings with routine permissions, a PreToolUse guard (merge of pull requests, Git hook bypass, force push without lease) and a SessionStart state report. Hooks are TypeScript, linted and tested (mutation-checked). CLAUDE.md shrinks from 151 to 118 lines; no rule lost (keyword comparison).

  • test(backlog): check every item in the table of its parent The F01 story table still showed EN-001, US-001, EN-002 and US-002 as draft: the test only compared folder indexes. It now also compares the stories table of each feature and the features table of each epic; the four rows are fixed. Refs: ADR-0020 Files: backlog.test.ts, docs/backlog/features/E01-F01-rectangle-with-corner-radius.md.
  • docs(backlog): interview the Product Owner and use the auditor in audits Refinement starts with an interview of the Product Owner; the audit template and AUD-001 use the auditor subagent and add the missing properties of the F01 functions merged before ADR-0022.

  • docs(adr): inspect each feature with a demo and each epic with a review ADR-0023: plain-language demo page and guided test at each feature validation; epic review (report, user test) and retrospective (evolvability review, playbook) at each epic; improvement log fed continuously. Markdown stays the backlog source of truth, GitHub Projects not adopted. Three references read on 2026-10-08 (Kanban guide, fitness functions, GitHub Projects). Refs: ADR-0023 Files: docs/adr/0023-inspection-cadence.md, docs/adr/README.md, docs/references.md.
  • docs: add the process, guide and playbook sections Process: cadences, evolvability review, improvement log, retrospective template. Guide: plain-language pages for the Product Owner, with demo and epic report templates. Playbook: principles, setup checklist, process, agent use and lessons, reusable for future projects.

  • test(backlog): close every started epic with a review and a retrospective REV and RET stories belong to their epic and are listed in its Closing table; the test checks their presence and statuses (mutation-checked). E01 receives REV-001 and RET-001; VAL-001 gains its demo page task.

  • docs(backlog): set F01 and E01 in progress The Product Owner agreed on 2026-10-08.

  • docs: write the feedback of the Product Owner on their behalf The Product Owner dictates by voice and never edits the repository: guide templates, process cadences, the review skill and the playbook say that the agent records their feedback, quoting them.

  • docs(adr): keep a session journal instead of a database ADR-0024: docs/process/journal.md records each session (requests, decisions, where recorded, #tags for grep), backfilled since 2026-10-07; the local transcripts are the full archive, searched with grep and jq; no database. Refs: ADR-0024 Files: docs/adr/0024-session-journal.md, docs/adr/README.md, docs/process/journal.md, docs/tooling/agent.md.
  • docs: extend the writing rules Voice (Microsoft and Google guides), word list including the French false friend contour, page skeletons, and a fixed shape for end-of-task messages to the Product Owner. Five references read on 2026-10-08. Refs: ADR-0023 Files: CLAUDE.md, docs/conventions/writing.md, docs/references.md.

  • docs(adr): keep the core portable to any engine and language ADR-0025: ECMAScript only in the functional core, plain data, mathematical intent stated where JavaScript differs from other languages, binary64 numbers. Host globals (Node.js, fetch, Intl, structuredClone...) banned by lint in the pure layers. Domain vision gains its purpose; draft epic E12 for a trusted release.

  • ci: close pull requests from outside contributors ADR-0026: the agent writes every change; external-prs.yml closes pull requests whose author is not the owner, a collaborator or Dependabot, pointing to the issue forms; it never checks out their code. /triage presents open issues to the Product Owner with a recommendation; issue content is untrusted data.

  • docs(adr): trace acceptance criteria to tests and releases ADR-0027, without adopting the V-model: feature criteria are the requirements (F01.ACn, ISO/IEC/IEEE 29148 qualities), never rewritten once done; tests proving a criterion carry its id, checked for done features (mutation-checked); a test strategy section; the V-model documents mapped in Process.

  • ci: merge labeled story pull requests into their feature branch story-automerge.yml enables auto-merge (rebase, built-in token) on owner pull requests labeled autonomous whose base is a feature branch and whose head is a US, EN, SP, CHK or AUD story; GitHub merges once the required checks of the new feature branches ruleset pass. Nothing reaches main this way. Branch names feature/f01-<topic> allowed. Refs: ADR-0028 Files: .github/workflows/story-automerge.yml, docs/tooling/ci.md, package.json.
  • docs(adr): add feature branches and autonomous runs ADR-0028, authorized by the Product Owner: one short-lived branch per feature; stories chain overnight on it, reviewed by the auditor and merged by GitHub when green; local previews at VAL, then the feature pull request into main merged by the Product Owner, one release per feature. Git workflow, releases, method, cadences, playbook and CLAUDE.md updated; two GitHub references read on 2026-10-08.

  • build(deps): update happy-dom to 20.14.6 Refs: AUD-001 Files: package-lock.json, package.json.
  • chore(tooling): wait for CI by reading its statuses Product Owner request: poll the pull request state and checks every 15 s, stop at the first failing check and read its log at once, give up after 12 minutes; a patch published meanwhile is updated on the branch and on main. Lesson added to the playbook. Refs: ADR-0028 Files: .claude/skills/run/SKILL.md, .claude/skills/story/SKILL.md, docs/playbook/lessons.md.

  • refactor(geometry): generalize cyclicVertex into cyclicItem Cyclic access serves vertices and per-vertex values (radii, setbacks, factors). The index is reduced with a non-negative modulo stated in the TSDoc rather than relying on the sign of the JavaScript remainder (ADR-0025). turningAngles, rules and notes updated.

  • feat(geometry): compute setbacks, edge lengths and edge factors Corner pairs a vertex with its requested radius. cornerSetbacks applies DERIV-local-radius-clamp step 1; edgeLengths, edgeFactor and edgeFactors step 2, testing S <= L before dividing so that a zero-length edge gives 1. Tests from the check table, a zero-size rectangle and an aligned vertex; mutation of the comparison caught.

  • feat(geometry): clamp corner radii locally and proportionally vertexFactors takes the smaller factor of the two edges of a vertex; effectiveRadii composes the steps of DERIV-local-radius-clamp (ADR-0007). Criterion tests [F01.AC3] (1000 on 100, 12.5 on an edge of 25, circle), zero size without NaN, and two properties on random rectangles: radii never increase nor become negative, setbacks of every edge fit its length.

  • fix(geometry): return no turn on a zero-length edge whatever the zeros turningAngle gave pi when the outgoing edge had zero length after an incoming vector with negative components: atan2(+0, -0) = pi in IEEE 754. A zero-length edge has no direction, so the angle is 0 explicitly (ADR-0025), stated in the derivation and tested. Auditor findings also applied: factor ranges [0, 1], independent setbacks in the overlap property (mutation-checked), AUD-001 list updated, question on the effective radius without arc recorded for the Product Owner in US-003.

  • feat(model): give the rectangle a global corner radius The requested radius is stored (integer >= 0, validated, a radius larger than the rectangle stays valid); rectangleCorners pairs each vertex with it; effectiveCornerRadius derives the radius actually drawn (Q8, ADR-0007). Tests [F01.AC2]: radius 10 on 100 x 50, 12.5 for 100 on 100 x 25, rounding following the size; property: never above the requested radius, never shrinking when the rectangle widens.

  • feat(playground): round the rectangle corners with a radius input Radius input next to width and height; the effective radius is shown and said to be reduced to fit when it differs from the requested one (Q8); the path is the rounded contour; the panel shows the evaluated segments and arcs. Checked with a smoke run in happy-dom (120 x 80 radius 10, 100 x 25 radius 100 -> 12.5, invalid radius), which caught a radius never read; logged as a future permanent test.

  • docs(docs): diagrams written in Mermaid, the method on one page A mermaid code block is drawn by the site's theme and by GitHub: the feature lifecycle, the branch history and the source library's flow are text kept with their pages. The method page explains the levels, the story types, who does what, and the cadences, among them a review of every rule every four to five epics.

  • docs(backlog): plan the debt of E01 in F11, before curves; where we are A feature of E14, first in its order: shared test helpers, one path writer, property tests for the nine functions without one, and the folder layout researched before the files move. Its stories, the review and the retrospective of E14 are drafts. The backlog's front page says which epic is done, current and next.

  • chore(tooling): a status line of three lines, with the backlog place and the call running The first line names the epic, feature and story of the branch and the agent's step; the second, the session: active or silent, running time, exact tokens, how full the conversation memory is, the model; the third, the tool call running and for how long, written by a new PreToolUse hook. Refreshed every second; usage limits left out, Claude Code shows them.

  • chore(tooling): rules for any agent in AGENTS.md, five expert agents, skills updated The rules any coding agent needs move to AGENTS.md, which CLAUDE.md imports before what only Claude Code uses. A doc-editor agent joins the auditor, math-expert, verifier and functional-analyst; the skills start them in the background, search the source library first, keep the terminal quiet during a run, write results in neutral words, and read the metrics at each retrospective.

  • docs(docs): retrospective record of E01; logs emptied, journal condensed Every item of the improvement and feedback logs is decided in the record, with where it went; the rows still to do later start the new improvement log; the feedback rows became the playbook's sheet of habits.

  • fix(docs): diagrams drawn without the XML error, every diagram parsed by a test Mermaid writes HTML inside its SVG labels (a <br> without a closing slash), which the XML parser refused: the drawing is now read as HTML. A test parses every Mermaid block of the docs. The README, the home page, the history before 0.1.0 and the last stale words follow the new workflow.

  • chore(tooling): count the uses of the source library Each search and each page read is recorded; npm run library -- stats and the Sources section of npm run metrics rank the sources consulted most, the words searched, and the share of pages served without going online. The retrospective reads them and asks why, then writes the agent's own account of the epic.
