Used in `Button.tsx` like `twMerge(cx(...))`. +- Tailwind 4 (`tailwindcss: ^4.2.1`) and `@tailwindcss/postcss` are installed. +- Components consume tokens from `base-tailwind` + `picasso-tailwind` preset paths. + +Implication for the migration: **styles are already expressible in Tailwind; the migration is largely rewriting `styles.ts` files from JSS to Tailwind utility arrays, plus swapping underlying components from `@material-ui/core` to `@mui/base`**. The styling system itself is decided. + +### 1.4 Reference implementations (Phase 0) + +- `Button.tsx` — canonical Tailwind-migrated component. 186 lines. `styles.ts` is a set of helper functions returning Tailwind class arrays (e.g. `createSizeClassNames`, `createVariantClassNames`). Uses `classnames` + `twMerge`. +- `Switch.tsx` — 115 lines, even simpler: no `styles.ts`, pure `cx(...)` inline + `@mui/base/Switch`. +- Button is a better reference because it has all the shapes (variants, sizes, slot-style icon composition). Switch is a good "minimal" reference. + +### 1.5 Codemod infrastructure (already here) + +- `@toptal/picasso-codemod` package with `jscodeshift`, `meow` CLI, fixtures-based test structure (`__testfixtures__/*.input.tsx` + `*.output.tsx` + `__tests__`). +- Active versions: `v5.0.0` through `v52.2.0`. New breaking changes get a new version folder with `index.ts`, `.ts`, fixtures, and tests. Pattern is well-worn. +- Utilities under `src/utils` handle import manipulation (`addImportMember`, `findSpecifierForImport`, `isImportFor`). + +Implication: **codemods are not a Phase 2 greenfield problem. We extend an existing framework** (P2-MOD-02). The AI-assisted part is generating the codemod body from the before/after component change. + +### 1.6 Testing (already here) + +- **Jest unit tests**: `packages/base//src//test.tsx` + `__snapshots__/`. Custom `@toptal/picasso-test-utils` wrapper ships `PicassoProvider`. +- **Cypress component tests**: `cypress/component/.spec.tsx`. 53 component specs. +- **Happo visual regression**: `yarn happo` / `yarn happo:storybook`, plus `happo-cypress` for Cypress-rendered stories. Baselines are in Happo cloud. +- **Storybook**: 6.5 with a custom `PicassoBook` wrapper. Every component has a `story/` folder with `*.example.tsx` files + `index.jsx`. + +### 1.7 Agent Experience artifacts + +- `bin/generate-docs.mjs` exists (Phase 0) — produces `llm-docs/` output, but that folder is git-ignored / not committed in the working tree at time of reading. +- **No** `.picasso/` folder, `CLAUDE.md`, `.cursorrules`, or `llms.txt` in the Picasso repo yet. These land in P1-AIC-01 / P1-AIC-03. +- No `.figma.tsx` files (Code Connect starts in P1-FIG-01). + +### 1.8 Phase 0 AI migration result (Button + Switch) + +Per PI-4318 prose + the observable repo state: Button + Switch were migrated via a Codex prompt ([PR #4906](https://github.com/toptal/picasso/pull/4906)). Both are now Tailwind + (for Switch) `@mui/base`. Button went through `.figma.tsx`-free because Code Connect didn't exist yet, but we have test parity. + +Open question: **the exact Phase 0 prompt is not versioned in the repo**. It needs to be retrieved and made a first-class artifact of this plan (§5). + +--- + +## 2. Migration targets (what "migrated" means) + +A component is migrated when all of the following are true: + +### 2.1 Dependency exits + +- **Zero `@material-ui/core` imports** in source. This is the primary MUI v4 exit. +- **Zero `@material-ui/styles` imports** (including `makeStyles`, `withStyles`, `createStyles`, `Theme`). +- **Zero `jss`-specific selectors** (`&$expanded`, `&$disabled` parent-refs). +- Package's `package.json` no longer lists `@material-ui/core` in `dependencies` or `peerDependencies`. +- If the component has an `@mui/base` equivalent, it's used. If not, the primitive is implemented with `@mui/base/useX` hooks or plain React. +- `PicassoProvider.override(() => ({ MuiX: ... }))` calls are removed (they don't apply once the underlying component isn't MUI v4). + +### 2.2 Styles on Tailwind + +- All CSS lives in Tailwind utility classes, authored via `cx(...)` + `twMerge` (pattern from Button). +- `styles.ts` either (a) is deleted, or (b) contains helper functions returning `string[]` of Tailwind classes (pattern from Button). No JSS objects. +- Raw hex / px values in source are converted to tokens from `@toptal/picasso-tailwind` / `@toptal/base-tailwind` presets when a token exists. Where a value has no token equivalent, a comment documents the gap (input to P1-FIG-03). +- Dynamic / runtime-computed styles use Tailwind's arbitrary-value syntax (`[--var]`, `[color:var(--foo)]`) or `style={{ ... }}` for numeric interpolation — the Page component already demonstrates this pattern. + +### 2.3 API preservation (default) + +- Public prop surface unchanged vs `master` pre-migration. +- If a prop must change (legitimately — e.g. an MUI-leaked prop that can't be preserved), it lands behind a semver-major with a codemod in `picasso-codemod` (§7). + +### 2.4 Tests green + +- `test.tsx` — Jest green, snapshot intentionally regenerated if class names change (unavoidable; documented in PR). +- `cypress/component/.spec.tsx` — green. +- Happo — diff reviewed by designer. Accepted diffs documented in PR body with the rationale. +- React 19 smoke suite (see §6) — green. + +### 2.5 `.figma.tsx` validity + +- If a `.figma.tsx` exists for the component (from P1-FIG-01), it still parses, its Figma node still resolves, and the snippet it emits matches the new prop surface. + +--- + +## 3. Component inventory + tiering + +Tiered by **migration complexity** (LOC in `.tsx` + `styles.ts`, surface of MUI v4 usage, number of subcomponents, theme-override presence). A machine-produced audit script (see §9) will re-rank this before Phase 2 kickoff; this initial tiering is read-by-hand. + +### Tier 1 — Leaf, small surface (≤150 LOC, zero or one child component) + +Cheapest to migrate.

The Maestro team on PF-2012/2013. **Modernization migration tickets (PF-1994/2020/2021/2022/2023) need only peer code review** — pixel-perfect Happo parity is the target, no design sign-off required. +- **Codemod dependency chain.** P2-MOD-06 codemods author *progressively* as P2-MOD-01..05 land breaking changes; the L estimate stretches across most of Phase 2. +- **Phase 2 critical path.** P2-MOD-01 (PF-1994) blocks the three sibling-package migrations and the provider rewrite. Critical path: P1-MOD-01/02 → P2-MOD-01 (PF-1994/2024/2025) → P2-MOD-05 → P3-MOD-01 ≈ ~28-35 man-days serial (P3-MOD-02 excluded). That's the floor for a single engineer doing only Modernization. +- **Coordination overhead.** Add a flat **+15%** for PI-level coordination if you need a calendar-realistic envelope. +- **Local Happo runs.** Per Vedran's note, running Happo locally from a branch (rather than waiting for CI) compresses iteration loops further. If wired up early in Phase 2 (would fit nicely as a P1-MOD-01 sub-deliverable), per-component multipliers could compress another ~10-20%. + +Two-engineer parallel scenario (one on Modernization, one on Agent Experience + Figma + Maestro): roughly **3 months wall-clock** for the 28 Jira tickets, gated mostly by designer's review bandwidth and the Happo cycle floor. + +Single-engineer scenario: roughly **5-6 months wall-clock**. + +--- + +## Out-of-scope tickets + +All three Phase-3 stories are explicitly excluded from PI-4318 scope: + +| Story ID | Summary | Reason | +|---|---|---| +| ~~P3-MOD-02~~ | ~~Migrate other consumer repos (16)~~ | Out of PI scope — other-team responsibility via self-service AI prompts | +| ~~P3-MAE-01~~ | ~~Maestro onboarding sessions + quick-start + docs~~ | Out of PI scope — deferred to post-PI | +| ~~P3-MAE-02~~ | ~~Maestro defaults to Picasso for new projects~~ | Out of PI scope — deferred to post-PI | + +Program in-scope total: **102 – 149 man-days = ~20–30 person-weeks** — solidly **M** at the Toptal scale. + +--- + +## Open assumptions to verify before locking estimates + +1. **Local Happo wiring.** Vedran's note suggests running Happo from a local branch is faster than CI. If true and easily set up, fold this into PF-1992 deliverables and re-derive multipliers downward by ~10-20%. +2. **TypeScript upgrade (R1 in migration plan).** Currently TS 4.7. 5.4+ is a Phase 2 prerequisite. If scoped into PF-1992, already covered; if separate, add ~2-3 d. +3. **React 19 peer-dep cap.** Lifting it is a per-package codemod (~0.5 d), bundled into per-component migrations. Already implicit in PF-1994 estimate. +4. **`@base-ui/react` vs Radix/Floating-UI for Popper / Tooltip / Grid.** PR #4906 is on `@base-ui/react`. Migration plan §9.8 flags this as a live decision. If we switch primitives mid-program, add ~1-2 d per affected component for re-spike. +5. **AI agent of choice.** Estimates assume Claude Code (plan + yolo mode) as the per-component driver, calibrated against Codex (PR #4906). Switching agents shifts costs by ±15%. +6. **Codemod count.** Estimated 8-12 codemods for PF-1995. If PF-2023 (provider) introduces more API breaks than expected (e.g. removing `PicassoProvider.override` use sites), codemod count grows; add ~0.5 d per codemod. +7. **Reviewer availability.** Only PF-2001 (per-component dos/don'ts) and PF-2000 (Phase 1 gate-run brand-fidelity rubric) require designer. Modernization migration tickets (PF-1994/2020/2021/2022/2023) do **not** require designer — pixel-perfect Happo parity is the bar, and any visual diff that surfaces is a bug to fix, not a design call. If designer's allocation is <30% during Phase 1 gate or PF-2001 review, those calendars stretch; rest of program is unaffected. +8. **Tier 3 surprise factor.** Estimates for Page, Accordion, Dropdown assume the JSS parent-ref unwinding is mechanical. If we hit architectural surprises (e.g. `PicassoProvider.override` chains we didn't audit), per-component cost can double. Mitigation: front-load `PicassoProvider.override` audit in PF-1992 (already in migration plan §9.5). + +--- + +## Update cadence + +This doc is a snapshot. Update when: + +- A ticket completes — replace estimate with actuals; track variance. +- After P2-MOD-01 (PF-1994) finishes Tier 1 (first 7 components) — re-calibrate Tier 2/3 multipliers from real data. +- When the 3 missing Phase-3 stories land in Jira — fold their estimates into the totals. +- If the AI agent stack or Happo workflow changes materially — re-derive multipliers. + +--- + +## Changelog + +- **v8 (2026-04-28)** — Reconciled doc IDs to actual Jira keys.

P2-FIG-03 (proposed local ID) → **PF-2027** (BASE spec gaps remaining 55, new key). Source ticket count updated 26 → 28. No estimate or schedule changes — pure key reconciliation. +- **v7 (2026-04-27)** — **PF-2001c removed** (designer dos/don'ts review pass folded into PF-2001). designer reviews each component's dos/don'ts during docs-generation work; engineer absorbs feedback iteratively. PF-2001 estimate bumps slightly from 8-10d to 9-11d to absorb the ~1d engineer absorption overhead. Net savings: ~1d per program (the PF-2001c handoff overhead). PF-2001 split: 3 → 2 sub-tickets. AIC track: 25-37 → 24-35d. Program: 103-151 → 102-149d. +- **v6 (2026-04-27)** — Added **PF-2027 (Update BASE Design System spec gaps for remaining 55)** as a new Figma-track ticket symmetric with PF-2006 (top-20). 10-12d total (mostly designer time). Required prerequisite for PF-2009 (Code Connect 55) to generate clean snippets — without it, BASE/Picasso prop-name mismatches would cause incorrect Code Connect output for some of the 55. Figma track total: 21-30 → 31-42d. Program total: 93-139 → 103-151d. +- **v5 (2026-04-27)** — Scope changes: (1) **PF-1994 split into 3 tier-tickets** PF-1994 + PF-2024 + PF-2025 (~3.5 + 4.5 + 6d, total unchanged at ~14d). (2) **PF-2001 split into 2 sub-tickets (PF-2001c folded into PF-2001 in v7)** PF-2001 + PF-2026 (component docs + Skills + designer review). (3) **PF-1995 reduced 8-10d → 2-3d** — replaced full codemod suite with AI agent + migration prompt + worked examples; codemods become escape hatch. (4) **PF-1996 reduced 6-10d → 1.5-2.5d** — Staff Portal only; other Portals out of PI scope. (5) **PF-2002 reduced 2-3d → 0.5-1.5d** — Staff Portal only. (6) **PF-2003 reduced 4-5d → 1-1.5d** — npm-bundled into `@toptal/picasso` instead of separate distribution package. (7) **PF-2008 reduced 5-7d → 2.5-3.5d** — assumes existing `@toptal` registry. (8) **PF-2004 + PF-2010 excluded** from PI scope. (9) **P3-MOD-02 explicitly out of PI scope** — other-team self-service migration. Program total: 117-172 → 93-139 (saves ~25-35 man-days). +- **v4 (2026-04-27)** — Clarified that designer is **not** required for review of Modernization migration tickets (PF-1994/2020/2021/2022/2023). Pixel-perfect Happo parity is binary; any visual diff is a bug, not a design call. designer remains required only for PF-2000 (Phase 1 gate brand-fidelity rubric) and PF-2001 (per-component dos/don'ts). Man-days unchanged. +- **v3 (2026-04-27)** — Re-sized against Toptal's portfolio T-shirt scale (XS up to 20 person-days, S 21-50, M 51-150, L 151-450, XL 451-950, XXL 951+). All individual stories are XS (BAU); program is M (low end) to L (high end with overhead + missing stories). Man-days unchanged from v2. +- **v2 (2026-04-27)** — Recalibrated against [picasso PR #4906](https://github.com/toptal/picasso/pull/4906) actuals. Per-component multipliers reduced from 0.4-0.65× to 0.10-0.25×. Total program effort reduced from 319-400 to 117-172 man-days.

Shrink comes from: dropping verbose prose, deduping against component source, using abbreviations the agent expands via rules, and splitting into `llms.txt` (index) + `llms-full.txt` (Phase 2). Usability comes from explicit dos/don'ts, "use this when..." cues, and worked examples extracted from real code (tied to P1-AIC-03). + +### Key technical choices + +- **Parser** — fork Phase 0 Storybook → markdown parser; add a post-processor that (a) collapses types, (b) extracts MDX examples, (c) emits per-component `.md` with a fixed header schema. +- **Index format** — follow the `llmstxt.org` convention; one section per component + one per pattern category. +- **Rules structure** — `rules.md` split into: imports, theming, composition constraints, anti-patterns. Each rule has a 1-line example. +- **Size target** — `llms.txt` under ~50 KB (token-budget friendly for in-context use). + +### Integration points + +- Produces the core input for Cursor / Claude Code + Figma MCP pipeline. +- Consumes from P1-AIC-03 (patterns) and P1-AIC-02 (top-20 selection). +- Rules reference tokens verified in P1-FIG-03. + +### Risks & open questions + +- Different agents weight sections differently — need smoke tests on Cursor, Claude Code, and Figma Make to find a shape that works across all three. +- `llms.txt` vs `llms-full.txt` split: when is each preferred?

Output: a ranked CSV and a top-20 list, with a sanity pass from designer to swap in any design-intent-critical component that under-ranks on pure frequency. + +### Key technical choices + +- **Tool** — TypeScript + `ts-morph` or `jscodeshift` to parse imports and JSX element names reliably (not regex). +- **Traversal** — list active repos from `toptal/*`; clone shallow; run analyzer in parallel; aggregate to SQLite or just a JSON. +- **Weighting** — by default equal-weight usages; optionally weight by repo LOC to avoid tail repos dominating. Document which weighting we picked. +- **Output** — `pilot/top-20.md` (list + rationale) and `pilot/usage-raw.csv` (full data). + +### Integration points + +- Blocks every Phase 1 Figma story (they all scope to top-20). +- Reused in Phase 2 for coverage verification (75/75). +- The analyzer itself graduates into the pilot harness — reused for pattern mining. + +### Risks & open questions + +- Monorepos with internal re-exports ("wrap Picasso in a local Button") — need to follow re-export chains to count real usages. Flag for Day-1 spike. +- Components used heavily but in maintenance mode (not what we'd design new apps around) — designer override. +- Access to all 23 repos — confirm auth approach (GitHub App vs PAT) up front. + +--- + +## P1-AIC-03 — Extract patterns from existing usage + +### Approach + +Reuse the analyzer from P1-AIC-02 to collect top composition patterns — sequences of Picasso components that co-occur (e.g., `Form → Input → Select → Button`). For each cluster, emit a pattern doc with: description, when-to-use, real-world file-path citations, recommended Picasso snippet. AI-assisted summarization, designer review. + +### Key technical choices + +- **Pattern mining** — AST-based co-occurrence within sibling-proximity windows (5 nodes), clustered by structural similarity. Tree-based diff (not string). +- **AI-assisted summarization** — pass each cluster to Claude with a structured prompt, get a draft description; designer reviews + corrects. +- **Output** — `/.picasso/patterns/*.md` (forms, layouts, navigation, data display at minimum). + +### Integration points + +- Feeds `.picasso/rules.md` (P1-AIC-01). +- Foundation for `picasso-page` Skill in Phase 2 (P2-AIC-01). +- Validates the top-20 selection — if a top-20 component barely appears in patterns, flag it. + +### Risks & open questions + +- Anti-pattern noise — "this is how apps use Picasso" is not the same as "this is how they should use Picasso". designer pass filters anti-patterns out. +- Pattern granularity — too narrow and we have 100 patterns; too broad and they're not actionable. Aim for 10-15 patterns in Phase 1, expand in Phase 2. + +--- + +## P1-AIC-04 — Collect measurements (harness + baseline + gate) + +### Approach + +Build the harness per the cross-cutting stack (above). Three-stage delivery: (1) runner + one scoring script working end-to-end on one reference design by mid-wk1, (2) all scoring scripts + baseline report by end of wk1, (3) full pipeline run + gate report at end of wk3. Harness lives in the Picasso repo under `packages/pilot-harness/` so it's versioned with Picasso's lockfile. + +### Key technical choices + +- **Runner** — spawns `cursor-agent --prompt ` and `claude code --prompt ` with a deterministic config; captures stdout + written files. +- **Scoring** — each scorer is a pure function `(generatedCode, groundTruth) => Score`. Shipped as CLI + library so we can unit-test. +- **M1 (component accuracy)** — ts-morph walks imports + JSX element names, diff against ground-truth `{component, count}` mapping. +- **M2 (prop accuracy)** — per-JSX-element prop diff, tolerance for synonym props (e.g., `variant="primary"` vs `primary`). Tolerance table maintained per component. +- **M3 (token fidelity)** — regex+AST scan for hex/px literals, cross-reference against `@toptal/picasso-tokens` allowlist. +- **M4 (Happo)** — render generated code in a minimal Storybook story, snapshot, diff against Figma PNG export. +- **M5 (rubric)** — Google Sheet with designer; aggregator ingests the CSV export. +- **M6 (timing)** — `pnpm pilot:time start|stop --screen=` writes to a local `timings.jsonl`. +- **M7 (lint)** — spawn `tsc --noEmit` + `eslint` on generated code. +- **M8 (diff size)** — `git diff --numstat` between first AI commit and merge commit, with business-logic annotations excluded. + +### Integration points + +- Consumes every other Phase 1 story. +- Graduates into Phase 2 as the regression harness for each new batch of covered components. + +### Risks & open questions + +- Variance in AI output — need to run each config N≥3 times and report mean + stddev, not single point. Budget compute accordingly. +- Figma PNG export fidelity for M4 — Figma exports anti-aliasing differently from Storybook/Happo. Calibrate tolerance threshold during baseline week. +- "Business logic" annotation for M8 — agree on a tag convention (`// BIZ-LOGIC` block comments) with pilot engineers Day 1. + +--- + +## P1-FIG-01 — Code Connect for top 20 + +### Approach + +Staged: (1) one-day BASE audit against top-20, producing a green/yellow/red table and gap list, (2) BASE gaps go to P1-FIG-02 for fixing, (3) token mapping (P1-FIG-03) lands in parallel, (4) author `.figma.tsx` per component, (5) publish via Code Connect CLI, (6) verify in Dev Mode + MCP. Two engineers can parallelize — split top-20 in halves. + +### Key technical choices + +- **`.figma.tsx` location** — next to component source (convention above). +- **Variant mapping** — prefer `figma.enum()` with explicit mappings over implicit. Document when Figma's variant name differs from Picasso's prop value. +- **Icons / slots** — use `figma.instance()` for composable slots. +- **Publishing** — `figma connect publish` in CI; gated on validator passing. +- **Verification** — a small script (`scripts/verify-code-connect.ts`) that queries Figma MCP's `CodeConnectSnippets` for each mapped component and diffs against the expected output. + +### Integration points + +- Blocked by P1-AIC-02 (scope), P1-FIG-02 (spec gaps), P1-FIG-03 (tokens). +- Blocks P1-AIC-04 gate run. +- Extends to 75/75 in P2-FIG-02. + +### Risks & open questions + +- Figma Code Connect API evolution — pin Code Connect CLI version and document it. +- Auth for MCP verification in CI — ephemeral token or skip MCP check in CI and run locally before PR merge. +- Components with runtime-composed children (e.g., `Table` with dynamic columns) — Code Connect's `figma.instance()` may not cover all cases. Document which top-20 components have limited mapping. + +--- + +## P1-FIG-02 — Update BASE spec gaps + +### Approach + +Driven by the audit output of P1-FIG-01. designer own the Figma-side edits; we provide the gap list, the Picasso-side prop names, and review the result. Cadence: 2-3 sync sessions across the 3 weeks. + +### Key technical choices + +- No code-side work — this is Figma design edits + documentation. +- Deliverable artifact: changelog in DS Confluence / BASE page, listing component-by-component what changed. +- Validation: P1-FIG-01 re-runs its audit after each batch of BASE edits and reports green/yellow/red delta. + +### Integration points + +- Blocks P1-FIG-01 for any red-status component. +- Feeds Phase 2 expansion to 75 components (P2-FIG-02) — surface anything that'll block 55 remaining components. + +### Risks & open questions + +- BASE is shared across products — changes may impact other consumers. DS team's call on what's safe in Phase 1 vs deferred. +- Timing — if BASE edits slip, P1-FIG-01 has to work around (swap from top-20 or publish Code Connect with known caveats). + +--- + +## P1-FIG-03 — Verify design token mapping + +### Approach + +Extract the token list from BASE Figma (colors, spacing, typography) and cross-reference against `@toptal/picasso-tokens`. Produce a mapping doc (`/.picasso/tokens/*.md`) with each BASE token → Picasso token name + any gaps. Gaps are fixed in Picasso tokens, BASE tokens, or mapped via an aliasing layer. + +### Key technical choices + +- **Token extraction** — Figma Variables API or Figma Tokens plugin export (JSON). Script the parse. +- **Cross-ref script** — small TS tool that loads BASE JSON + Picasso tokens and emits a diff report. +- **Output format** — per category (`colors.md`, `spacing.md`, `typography.md`) with a table: BASE name, Picasso name, status (match / alias / gap). + +### Integration points + +- Feeds `.picasso/rules.md` — "always use token X, never raw hex". +- Unblocks Code Connect authoring (P1-FIG-01) for any component that references tokens. +- Used by M3 scorer (allowlist of valid tokens). + +### Risks & open questions + +- Dark mode — BASE has it, Picasso may not. Flag and decide if Phase 1 covers or defers. +- Semantic vs primitive tokens — BASE may expose semantic tokens ("color-bg-primary") that map to Picasso primitives. Document the aliasing strategy. + +--- + +# Phase 1 — Non-gating parallel + +## P1-MOD-01 — Migration plan for AI-assisted Picasso migration + +### Approach + +Plan doc, not code. Audit the 75 components, bucket by complexity (tier 1: pure presentation, tier 2: stateful, tier 3: composite / portal-using / custom-theming), and define per-tier migration playbook. Build on the Phase 0 Button + Switch success — the prompt + testbed setup worked; formalize it. + +### Key technical choices + +- **Complexity tiering** — static audit (LOC, MUI v4 surface used, JSS rules, child components). Script it so re-running on a new MUI release is trivial. +- **Testbed setup** — Storybook + Happo + Jest is the existing per-component gate. Document the AI-migration wrapper: (a) pin a branch, (b) run prompt, (c) run tests, (d) if Happo diff > threshold, stop and escalate. +- **AI prompt** — reuse Phase 0 Codex prompt; rewrite for Claude Code + Cursor as alternates. Version-control the prompt. +- **Risk register** — React 19 compat, JSS → Tailwind edge cases (nested selectors), MUI-internal-API leakage, `.figma.tsx` invalidation. + +### Integration points + +- Blocked by the Agent Experience output from Phase 1 (better context = better migration output). +- Blocks Phase 2 execution (P2-MOD-01). + +### Risks & open questions + +- AI agent quality lift between Phase 0 and Phase 1 — by the time we run this, Claude + Cursor may have moved. Re-validate the prompt before Phase 2 kicks off. +- Components that don't cleanly migrate (heavy JSS, MUI internals) — document the escape hatch (manual migration lane). + +--- + +## P1-MOD-02 — Migrate Picasso to pnpm + +### Approach + +Follow the internal pnpm migration tutorial (referenced in the PI ticket). This is a mechanical migration: replace yarn.lock, update CI, fix workspace protocol references, validate. + +### Key technical choices + +- **Workspace format** — `pnpm-workspace.yaml`. +- **Lockfile** — `pnpm-lock.yaml`; delete `yarn.lock`. +- **CI** — swap `yarn install` → `pnpm install --frozen-lockfile`. +- **Husky / lint-staged** — pnpm equivalents. +- **Hoisting** — evaluate `node-linker=hoisted` if we hit MUI peer-dep issues during Phase 2 migration; default is isolated. + +### Integration points + +- Co-dependent with PI-4278 (Platform Core Q2). +- Unblocks Tailwind 4 install (P2-MOD-01 depends on this). + +### Risks & open questions + +- Jest / Cypress config relying on hoisted node_modules — worth a spike first. +- Internal scripts that assume yarn-specific commands — grep `package.json` and `.github/` for yarn refs before starting. + +--- + +## P1-MAE-01 — Figma Middleware PoC + +### Approach + +CLI tool that consumes a Figma file URL + node id via Figma REST API, walks the node tree, and emits a structured JSON describing components + tokens + layout. Proof that Maestro can bypass Figma MCP. No integration yet; just stdout → JSON. + +### Key technical choices + +- **Language** — Node + TypeScript (aligns with Maestro's stack). +- **Figma API** — `/v1/files/:key` + `/v1/files/:key/nodes`, with a PAT for auth. Rate-limit aware. +- **Output shape** — JSON with `components: [{ id, name, props, children, tokens }]` — designed to mimic what Figma MCP returns so Maestro can swap providers without refactoring. +- **Code Connect integration** — read `.figma.tsx` via the Code Connect API (or parse locally) and enrich the output with snippet mappings. This is the middleware's unique value vs raw Figma API. + +### Integration points + +- Compared head-to-head with Figma MCP — produces the Phase 2 go/no-go for productionization (P2-MAE-01). +- Uses Code Connect output from P1-FIG-01. + +### Risks & open questions + +- Figma REST API rate limits on large files — batch requests, cache aggressively. +- Variant / component-set traversal semantics differ from what MCP exposes — spike early to confirm parity is reachable. +- Deep composition (component-of-component) — how many hops do we support?

Slack webhook for orchestrator notifications + +### Decision + +Implement Slack webhook notifications. Wire as part of PF-1992 (not deferred to PF-1994). Events fired: escalation, tier-started, tier-completed, run-failure. Not chatty — ~5–15 messages per tier total. + +### Rationale + +Without it, the only way to find out about an escalation is checking the manifest or noticing a process has stopped logging. With ~30 PRs, parallel-pipelined runs, and 5-min CI polling, you can't sit on top of it. Escalations need to interrupt actively, not passively. + +Specifically: +- 30-minute review-poll cadence means escalations fester before being noticed without a notification. +- Auth failures cascade silently — every component fails until you re-auth. +- Pipelined parallelism means components are running unattended in the background. + +### Implementation + +1. Create Slack incoming webhook (point at `#picasso-modernization` channel or DM). +2. Set env var `PICASSO_ORCH_SLACK_WEBHOOK="https://hooks.slack.com/services/..."` (or load from `.env`). +3. In `bin/lib/orchestrator-core.ts`, add a `notify(event, payload)` helper that POSTs JSON to the webhook URL if set, no-op if not. +4. Fire events at the appropriate state transitions: + - `escalation` — component name, trigger reason, PR URL, link to escalation log + - `tier_started` — first component of a new tier picked up + - `tier_completed` — all components in a tier merged + - `run_failure` — orchestrator process crashed or hit auth failure +5. Don't block the orchestrator on the webhook call. Log failures, continue. +6.

Happo verification on canary + +### Decision + +Verify Happo wiring on the Note canary run before any real migration. Add this as a checklist item to PF-1992 acceptance criteria. + +### Rationale + +Currently `MIGRATION_GATE_HAPPO=skip` is the default for sandbox runs. The Note canary should override that and actually run Happo, so credentials and project setup get tested before scaling. Better to find missing API key/secret on Note (where we expect zero diffs) than to find it on Tooltip (where we'd be debugging two layers at once). + +### Implementation + +Run: `MIGRATION_GATE_HAPPO=run yarn orchestrate --component=Note --no-merge` + +Verify: +- `HAPPO_API_KEY` and `HAPPO_API_SECRET` set in shell or `.env` +- `HAPPO_PROJECT=Picasso/Storybook` exists in Happo account, API key has write access +- `--only Note` filter actually picks up Note's stories (~5 expected — Note + Compound + Content + Subtitle + Title variants). If it picks up 0 or 200 stories, the filter isn't doing what we want. +- Happo CLI ends with a report URL that's diff-reviewable in the web UI +- Cloud rate limits don't bite (run a single canary, then 3 in parallel as a stress test) + +Note has zero source diff, so Happo *should* return zero diffs. Any diff = a transitive change to investigate (Storybook config drift, font loading, etc.). + +### Files to change + +- `docs/modernization/PI-4318-P1-MOD-01-migration-plan.md` §11 acceptance criteria — add Happo verification line +- `docs/migration/ORCHESTRATOR.md` — add Happo prereq check to "Verification commands" section + +--- + +## 10. Stricter Happo gate + +### Decision + +Tighten the Happo gate so it passes only when **either** zero visual diffs **or** all diffs are designer-accepted. Currently the gate just checks the Happo CLI exit code, which is 0 even with diffs (Happo treats diffs as "for review", not "build break"). + +Implement via Happo's REST API: after `yarn happo` runs, hit the report-summary endpoint and check `diffsTotal` plus per-diff `status`. + +### Rationale + +The current gate marks Happo PASS when the screenshot upload succeeded. Doesn't know whether the screenshots match the baseline. Tightening makes the gate enforce visual correctness at the agent-output level (rather than relying on PR review to catch the problem after merge). + +For Tier 1 + Tier 0 components (cleanup + light path) we expect zero diffs — so the gate's strict mode catches agent mistakes immediately. For Tier 2/3 where intentional visual changes can happen, designer accepts diffs in Happo's web UI; next gate run picks up the new state and passes. + +### Implementation + +Two-part change: + +**Part A — gate script (`bin/migration-gate.sh`):** + +After `yarn happo` runs, parse the report URL from the CLI output, then hit Happo's REST API: + +```bash +REPORT_SHA=$(parse from happo CLI output) +SUMMARY=$(curl -u "$HAPPO_API_KEY:$HAPPO_API_SECRET" \ + "https://happo.io/api/reports/$REPORT_SHA/summary") +DIFFS_TOTAL=$(echo "$SUMMARY" | jq '.diffsTotal') +UNRESOLVED=$(echo "$SUMMARY" | jq '[.diffs[] | select(.status != "accepted")] | length') + +if [ "$DIFFS_TOTAL" -eq 0 ] || [ "$UNRESOLVED" -eq 0 ]; then + STAGE_STATUS=PASS +else + STAGE_STATUS=FAIL + # Include report URL in the failure message so designer can review +fi +``` + +**Part B — orchestrator pre-merge check:** + +Before `gh pr merge --auto`, call the same Happo summary API. If unresolved diffs exist, post a comment to the PR ("Happo diffs unresolved, see ") and loop back to review polling instead of merging. + +This way: +- Gate fails fast on diff mismatch — agent rerun is targeted (the agent sees "Happo diff at slot X, see report" in the gate report). +- Merge step prevents auto-merge even if a code reviewer approves but the designer hasn't. + +### Files to change + +- `bin/migration-gate.sh` — add Happo API check after Happo CLI runs +- `bin/lib/orchestrator-core.ts` (or wherever the merge step lives) — add pre-merge Happo check +- `docs/migration/references/pr-workflow.md` — document the new merge precondition +- `docs/modernization/PI-4318-P1-MOD-01-migration-plan.md` §6.3 (Happo policy) — update to reflect that gate enforces this, not just policy + +--- + +## 11.

If yes, transition; if no, skip) + if agent is free and queue has unblocked items: + pick next, start migrating + if no in-flight components and queue is empty: + exit + sleep 5s +``` + +**Constraints.** +- Agent (Claude Code subprocess) is single-threaded per orchestrator process. Only one component in `migrating` at a time. Track via a single `agentBusy` boolean. +- Manifest writes already use atomic-rename. Don't add a mutex. +- Iteration cap (3 default) lives per-component. `--max-iterations=N` flag overrides for one run. +- Existing CLI flags (`--component`, `--tier`, `--dry-run`, `--no-merge`, `--agent`, `--max-iterations`) all still work. +- New CLI flag: `--tier=0,1` (multi-tier filter — fills in-flight queue from any tier in the comma-separated list). + +**Files.** +- `bin/lib/orchestrator-core.ts` — main refactor. Extract a `StateMachine` class or set of pure functions (your choice) that walks the state graph. +- `bin/lib/workflow.ts` — add hooks if needed for state-transition customisation. +- `docs/migration/references/agent-loop.md` — rewrite the 14-step list as state-machine transitions. Each state has: entry condition, work performed, exit transitions. Preserve the existing step semantics — just present them as state machine. +- `docs/migration/ORCHESTRATOR.md` — update the diagram + Quick start examples. + +**Acceptance.** +- `yarn orchestrate --tier=1 --dry-run` prints the planned in-flight rotation. +- `yarn orchestrate --component=Note --no-merge` (canary mode) still works as before. +- Unit tests for the state machine added under `bin/lib/__tests__/` (or wherever existing test infra lives — match the existing convention). +- Effort budget: 1-2 days. If it ballons past 3 days, stop and escalate — there's likely a simpler refactor. + +### Step 3 — Slack webhook + +**Goal.** Wire Slack incoming-webhook notifications into the orchestrator. Events: escalation, tier-started, tier-completed, run-failure. No-op if env var is unset. Per `PI-4318-PF-1992-design-decisions.md` §8. + +**Files.** +- `bin/lib/orchestrator-core.ts` — add a small `notify(event: string, payload: object)` helper. POSTs JSON to `process.env.PICASSO_ORCH_SLACK_WEBHOOK` if set. Don't block the orchestrator on the call; on failure, log and continue. +- Hook the `notify` call sites at the appropriate state transitions: + - `escalation` — when a component transitions to the `escalated` state.

Even though the light path is mostly a package swap, components must preserve their existing `classes` API (keep the prop, route through `withClasses`). + +**Files — rules:** +- `docs/migration/rules/api-preservation.md` — replace any "remove `classes`" guidance with "preserve `classes` via the slot-routing shim".
