 # @variscout/pwa
 
-Free PWA. Session-only (no persistence), Context-based state, education tier.
+Free PWA. Session-only by default; opt-in local persistence; education + training tier.
 
 ## Hard rules
 
-- No persistence. No IndexedDB, no localStorage, no cloud sync. Session ends, data is gone. This is the product principle.
+- **Session-only by default.** Opt-in IndexedDB persistence allowed only via explicit user action ("Save to this browser" → single Hub-of-one) AND/OR `.vrs` file export/import. `.vrs` files double as **shareable training scenarios** — trainers package datasets + Hub state; students import. No cloud sync (Azure-only). Per Q8-revised in `docs/superpowers/specs/2026-05-03-framing-layer-design.md` and `docs/decision-log.md` "Q8 revised" entry.
+- **No AI in free tier** (Constitution P8). CoScout is Azure-only.
 - Tailwind v4 requires `@source` directives in `src/index.css` for shared packages (`@source "../../../packages/ui/src/**/*.tsx"`, etc).
 - Free tier only — branding is shown in chart footers (`isPaidTier()` from `@variscout/core/tier` returns false).

+## Amendment — 2026-05-03: PWA local Hub-of-one (IndexedDB persistence stays browser-tenant-only)
+
+The 2026-05-03 product vision spec
+([`docs/superpowers/specs/2026-05-03-variscout-vision-design.md`](../superpowers/specs/2026-05-03-variscout-vision-design.md))
+§7 commits PWA to a **local Hub-of-one**: a single Process Hub persisted in
+IndexedDB, surviving page refresh and offline use. Same Canvas UX as the Azure
+tier (build map, set specs, run analysis, return later, data persists).
+Multi-Hub portfolio + cloud sync + cadence-driven Evidence Sources + CoScout
+
+- team features remain Azure-tier exclusive.
+
+This refines (does not change) the customer-owned-data principle established
+in this ADR:
+
+- **PWA local Hub data is browser-tenant-only.** IndexedDB lives in the user's
+  browser profile under the PWA's origin. No data leaves the device. No
+  back-end, no sync, no telemetry payload that could re-export user data.
+- **Constitution P1 (browser-only processing) holds.** The PWA continues to
+  process all data client-side; the only change is that processed data now
+  persists across sessions instead of evaporating on tab close.
+- **Constitution P8 (no AI in free tier) holds.** CoScout remains an Azure-
+  tier feature. PWA's local Hub never sees a CoScout prompt.

+## Amendment — 2026-05-03: Modes and levels are orthogonal axes
+
+The 2026-05-03 product vision spec
+([`docs/superpowers/specs/2026-05-03-variscout-vision-design.md`](../superpowers/specs/2026-05-03-variscout-vision-design.md))
+§5.4 sharpens the mode/level relationship into an explicit
+**orthogonality**:
+
+- **Modes** answer _which analytical lens are we applying?_ (capability /
+  yamazumi / defect / performance / process-flow). They re-skin Canvas
+  cards.
+- **Levels** answer _which slice of the process are we scanning?_
+  (System / Process Flow / Local Mechanism). They are expressed as a
+  Canvas pan/zoom state, not a separate picker.
+
+The two cross-cut: a user can read at any level in any mode. Level is
+**inferred from the Canvas zoom state**, not selected from a dropdown — so
+CoScout's level-aware overlays do not require any new user gesture; they
+read the current zoom state and adjust the tier1/tier2 prompt context
+accordingly.
+
+This refines (does not replace) the 2026-04-28 amendment above. The
+mode-aware coaching modules in `packages/core/src/ai/prompts/coScout/`
+continue to be the dispatch point; the level overlay reads the Canvas zoom
+state via the same context-builder pipeline (`coScout/context/`).

+## Amendment — 2026-05-03 (Superseded by Canvas; FRAME workspace retired as a top-level route)
+
+The 2026-05-03 product vision spec
+([`docs/superpowers/specs/2026-05-03-variscout-vision-design.md`](../superpowers/specs/2026-05-03-variscout-vision-design.md))
+**retires the FRAME workspace as a top-level navigation tab.** The Canvas
+absorbs both Frame and Analysis as a single continuous surface; the river-styled
+SIPOC metaphor is dropped as a user-facing visual; "tributary" terminology is
+retired (replaced by "factor" / "input arrow"); the FRAME tab disappears from
+the AppHeader in both PWA and Azure.
+
+This is decided in the §8 walk-through summarized in
+`~/.claude/plans/lets-do-this-next-rustling-simon.md` and the
+2026-05-03 Vision §8 resolution entry in
+[`docs/decision-log.md`](../decision-log.md). The migration mode is hard
+cutover (Q7 — no parallel-run, no back-compat) because VariScout has no
+production users yet to preserve.
+
+What survives from this ADR:
+
+- The deterministic mode-inference principle (rules from map shape + column
+  roles, not silent keyword guesses) — implemented as the Canvas mode-lens
+  picker per vision §5.4. The `inferMode()` helper at
+  `packages/core/src/frame/modeInference.ts` continues to seed the
+  suggested-lens prompt (vision §5.4 — "today's silent mode auto-inference
+  survives as a suggested lens prompt").
+- The data-gap-detector idea — the methodology declares what it wants
+  (CTS / per-step CTQ / xs / time axis / spec limits); data declares what's
+  there; gaps surface as a measurement plan. Re-homed onto the Canvas as
+  card-level affordances (e.g., the "+ Add specs" chip per vision §5.2).
+- The capability-storytelling leg (rational subgroups from the user-sketched
+  axes; mode-aware coaching) — survives unchanged inside the Canvas.
+
+What gets deleted in the same PR that ships the Canvas:
+
+- `apps/azure/src/components/editor/FrameView.tsx` and the PWA equivalent.
+- `packages/ui/src/components/LayeredProcessView/LayeredProcessView.tsx` +
+  `LayeredProcessViewWithCapability.tsx`.
+- `packages/ui/src/components/ProcessMap/ProcessMapBase.tsx`.
+- `FrameViewB0` (the b0 lightweight render from the 2026-05-02 amendment
+  below — its job is now the sparse-Canvas first paint when no map is
+  authored yet).
+- The Frame and Analysis tab buttons in `AppHeader` (PWA + Azure).
+- The river-SIPOC SVG primitives in `packages/charts/src/ProcessMap/`.
+- "Tributary" UI strings, i18n keys (`wall.tributary.ariaLabel`), and
+  related code comments.
+
+`JourneyPhase = 'frame' | 'scout' | 'investigate' | 'improve'` stays in
+`packages/core/src/types` because Investigation continues to use phase-based
+CoScout tool gating internally — but it no longer drives the top-level nav.
+
+The 2026-04-28 amendment ("FRAME as one flow lens within a layered process
+view") is now subsumed: the layered-view bands + the FRAME flow lens are all
+expressed on the Canvas (vision §5.4 mode lenses + §5.2 cards). The Layered
+Process View design spec at
+[`docs/superpowers/specs/2026-04-27-layered-process-view-design.md`](../superpowers/specs/2026-04-27-layered-process-view-design.md)
+should be re-tagged or archived as a follow-up.
+
+The 2026-05-02 amendment below ("FRAME b0 lightweight render") describes a
+component that is itself absorbed: `FrameViewB0` becomes the deterministic
+"sparse Canvas" first paint when `processMap.nodes.length === 0`. The
+two-archetype rationale (investigator b0 vs author b1/b2) survives as a
+Canvas-state distinction, not a separate component.
+
+This amendment marks the ADR as **superseded for the workspace-tab role**;
+the methodology principles cited in §1–§6 of the original Decision live on
+inside the Canvas surface.

 - **ADR-074 — SCOUT level-spanning surface boundary policy.** Each surface owns exactly one level of the three-level methodology (L1 outcome / L2 flow / L3 mechanism) and lenses the other two by linking to the surface that owns each level — never by re-rendering or recomputing. SCOUT owns L1 outcome reading; FRAME owns L2 authoring; the Hub Capability tab owns L2 reading; Investigation Wall owns L3 hypothesis canvas; Evidence Map owns L3 factor network; INVESTIGATE owns L3 case-building. Same enforcement mechanism as ADR-073: structural absence + CI guards, not permission predicates.

+- **2026-05-03 — Q8 revised: PWA persistence opt-in instead of default-on; `.vrs` files double as shareable training scenarios.** Original Q8 ("PWA = local Hub-of-one with IndexedDB persistence") was too aggressive — it would have surprised users on shared computers and conflated "PWA _can_ persist" with "PWA _must_ persist." Revised Q8 (Option 4 hybrid): session-only by default; opt-in via "Save to this browser" for IndexedDB-backed Hub-of-one AND `.vrs` file export/import always available. Both paths preserved as user-agency escape hatches. **Strategic rationale:** PWA serves LSSGB training, demos, casual personal analysis, and **trainers authoring custom scenarios for their students**. Trainers package datasets + Hub state + sample investigations into a `.vrs` bundle and share via LMS / email; students import the bundle to start from a prepared training state. This positions PWA as the methodology-teaching surface and `.vrs` as the scenario-distribution format. Each persona's persistence consent is explicit (training students opt in once and auto-save; demo users skip; privacy-conscious users export to file; trainers export+share). Companies still use Azure tier for centralized + secure persistence per ADR-059. Constitution P1 (browser-only processing) and P8 (no AI in free tier) preserved. `apps/pwa/CLAUDE.md` hard rule updated from "no persistence" to "session-only by default; opt-in IndexedDB allowed; `.vrs` import/export for trainer-shared scenarios." Vision spec §7 tier paragraph + §8 Q8 row updated.

Headlines: **Canvas eats Frame + Analysis tabs (Q0)** — Investigation / Improvement / Report keep their own surfaces; top-level nav post-cutover is `[ Hubs ] [ Canvas ] [ Investigation ] [ Improvement ] [ Report ]`. **Wall is dual-home (Q4)** — destination in Investigation tab AND a canvas overlay. **Drill-down is a modern floating overlay anchored to clicked card with blurred-canvas backdrop (Q1, overrides spec default)** — resolves the C3 supersession conflict with CoScout's right-rail claim; mobile slides up from bottom. **No CoScout map drafting in V1, manual canvas authoring is the path (Q5, overrides default)** — V1 commits to manual click / drag / connect as a first-class design concern; CoScout coaching role unchanged. **PWA gets a local Hub-of-one with IndexedDB persistence (Q8)** — single Hub, browser-tenant-only per ADR-059; Azure adds cloud sync + multi-Hub + cadence + CoScout + team features. **Hard cutover with no migration (Q7)** — no users yet to preserve, deletes happen in the same PR per the no-back-compat rule. **Horizons split out to a delivery-sequence reference doc (Q6).** **Glossary at `docs/glossary.md` becomes canonical (Q10)** — methodology.md cross-references it. **Promoted hypotheses render as node markers, drafts as faint arrows (Q11).** Vision spec §3.4, §5.2, §5.3, §5.4, §5.6, §5.7, §6, §7, §8 rewritten in place; §8 replaced "open questions" with a "resolved decisions" table.

 The running list of conversations / work, with lifecycle state. Done items stay with a closed-date for provenance; dropped items capture why. Each row links back to its source decision-log entry, so closing the work also resolves the upstream question. New conversations get logged as `queued` at session start; transition to `in-flight` when work begins; close with a link to the plan-file / PR / commit when done.

 # Glossary
 
-Statistical and quality terms used across VariScout.
+Statistical, quality, and methodology terms used across VariScout. **This is the canonical home for VariScout terminology.** Process narrative lives in [`docs/01-vision/methodology.md`](01-vision/methodology.md) and the [product vision spec](superpowers/specs/2026-05-03-variscout-vision-design.md); both cross-reference this glossary rather than re-defining terms.
+
+---
+
+## Process methodology terms
+
+Canvas vocabulary canonicalized by the 2026-05-03 vision spec (§3.3 commitment 9). The methodological CTS-vs-CTQ distinction survives as concept; the acronyms do not survive as user-facing labels.
+
+### Step
+
+A node on the Process Hub canvas. Represents one stage of the process flow. Steps connect via directed arrows (flow); each step holds zero or more inbound columns (inputs / measurements) and zero or more outbound columns (outputs / intermediate Ys).
+
+**Related:** [Sub-step](#sub-step), [Column](#column), [Outcome](#outcome)
+
+### Sub-step
+
+A child of a step. Two-level nesting only (no grandchildren). Tagged either **parallel** (default — siblings like chambers) or **sequential** (a sub-sequence inside the parent step). When parallel sub-steps converge to a downstream step, that step's analysis is automatically grouped by upstream origin (context propagation).
+
+**Related:** [Step](#step), [Branch](#branch--join)
+
+### Column
+
+A single column of incoming data, mapped to a step (or marked unassigned). Direction encodes meaning: column → step = input / control to the step; step → column = measured AT the step (output / intermediate Y).
+
+**Related:** [Step](#step), [Input](#input), [Output](#output)
+
+### Input
+
+A column whose arrow points INTO a step. The variable controlling, measuring, or describing what enters the step.
+
+**Related:** [Output](#output), [Column](#column)
+
+### Output
+
+A column whose arrow points OUT of a step. The variable measured AT the step. May feed into a downstream step or serve as the final outcome.
+
+**Related:** [Input](#input), [Outcome](#outcome)
+
+### Outcome
+
+The Y measure(s) on the right end of the canvas — what the customer experiences. System-level (Level 1) result of the process. Per Hub there is at least one outcome.
+
+**Related:** [Output](#output), [Step](#step)
+
+### Branch & Join
+
+A step can branch (one → many downstream paths) and join (many → one). Real processes do both. Branch / join structures are the load-bearing primitive for ADR-073 (no statistical roll-up across heterogeneous units): heterogeneous siblings cannot be silently averaged.
+
+**Related:** [Step](#step), [Sub-step](#sub-step)
+
+### Process Hub
+
+The persistent home of one process line. Hub IS its logic map — there is no separate Hub model and map model. Holds: map structure, specs per column / per step, named contexts, cadence definition, snapshot history, finding history, investigation history.
+
+**Related:** [Outcome](#outcome), [Step](#step)
+

+
+## Retired terms
+
+Terms removed from user-facing surfaces in the 2026-05-03 vision pivot. Listed here so future contributors recognize them in legacy code, comments, or external context. Do not reintroduce.
+
+| Retired term             | Replacement                                                                | Why retired                                                                                                                      |
+| ------------------------ | -------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------- |
+| **Tributary**            | _factor_, _input_, _input arrow_, or simply removed                        | River metaphor was load-bearing in ADR-070's FRAME workspace; canvas drops the river framing.                                    |
+| **CTS**                  | "outcome at the customer," "system outcome," or simply [Outcome](#outcome) | Acronym opaque to users; the CTS-vs-CTQ methodological distinction survives as concept.                                          |
+| **Critical-to-X**        | Plain language describing the relationship being asserted                  | Acronym family same as CTS — concept survives, label does not.                                                                   |
+| **River-SIPOC**          | _Canvas_                                                                   | The visual metaphor (left→right SIPOC; tributaries entering from banks) retired; the canvas uses spatial DAG with branch + join. |
+| **FRAME workspace**      | _Canvas_ (top-level surface)                                               | FRAME tab retires per Q0 in the §8 resolution. ADR-070 amended 2026-05-03 with supersession note.                                |
+| **Analysis tab**         | _Canvas_ + mode lenses (per vision §5.4)                                   | Same job as Frame — looking at the live map and its current state. Consolidated into Canvas.                                     |
+| **Layered Process View** | _Canvas_ with mode lenses                                                  | Three-band visual (Outcome / Process Flow / Operations) absorbed; semantic preserved as overlays.                                |
+| **Hub of Hubs**          | _Plant-hub layout_ (named-future, see decision-log)                        | Implementation term that surfaced in product-method roadmap; named-future in delivery-sequence reference.                        |

 **Goal:** Wire the production-line-glance dashboard into LayeredProcessView's Operations band with progressive reveal, in both azure-app and PWA. Land the `mode: 'spatial' | 'full'` prop on `ProductionLineGlanceDashboard`, the URL-state toggle hook (`?ops=full`), the slot-prop API change on LayeredProcessView, and the surface wiring in both `apps/azure/src/components/editor/FrameView.tsx` and `apps/pwa/src/components/views/FrameView.tsx`.
 
 **Architecture:** Three contract additions, no new components:
+
 1. `ProductionLineGlanceDashboard` gets `mode?: 'spatial' | 'full'` (default `'full'`). When `'spatial'`, the temporal row's wrapper transitions `max-height: 0` (no chart re-mounts).
 2. `LayeredProcessView` gets `operationsBandContent?: React.ReactNode` and `filterStripContent?: React.ReactNode` slot props. When `operationsBandContent` is provided, the band renders that node and the existing tributary chips relocate to the Outcome band's "Mapped factors" subsection. Default behavior (no slot props) is unchanged — preserves current FRAME usage.
 3. `useProductionLineGlanceOpsToggle` (new in `@variscout/hooks`) syncs the `ops` URL search-param to `'spatial' | 'full'` mode state with `replaceState` semantics matching `useProductionLineGlanceFilter`.

 **Type consistency:** `ProductionLineGlanceOpsMode` defined in T2 (`@variscout/hooks`) and T4 (`@variscout/ui`). The duplication is intentional: hooks owns URL state; ui owns composition. Both reduce to `'spatial' | 'full'` and are interchangeable.
 
 **Risk reminders:**
+
 - T5/T6 may discover that FrameView's data layer doesn't project cleanly to ProcessHubRollup. Pragmatic fallback: pass empty `data` props and document live-data wiring as V2 follow-up. The composition is the value; live data is icing.
 - The temporal row's `max-height` transition with content of unknown height (depends on viewport) needs the right CSS — use `max-h-screen` for full or rely on actual element height via `style.maxHeight`. T1 implementer chooses.
 - The "Mapped factors" subsection in Outcome band may overflow at small widths. Wrap chip list with `flex-wrap` (already in original code).

+title: Framing Layer V1 Slice 1 — Locked Decisions
+audience: [engineer]

+
+# Locked Decisions — Slice 1
+
+## D1. AnalysisBrief vs new types
+
+The existing `AnalysisBrief` interface in `packages/ui/src/components/ColumnMapping/index.tsx`
+sketched issue/questions/targetMetric but is unused today. **Decision:** do NOT extend
+AnalysisBrief. Create a clean `OutcomeSpec` type on `ProcessHub`. AnalysisBrief stays in
+its current sketched form for slice 5 (Stage 5 investigation entry); slice 1 leaves it
+alone. Reason: the framing-layer spec separates Hub-level (durable: outcomes + specs)
+from investigation-level (episodic: issue + question); conflating into AnalysisBrief
+re-merges what the spec just split.
+
+## D2. PWA persistence is OPT-IN per Q8-revised
+
+PWA persists ONLY after the user clicks "Save to this browser." Default is session-only
+(matches today's behavior). The Dexie schema is loaded post-opt-in only. The opt-in flag
+itself is stored in IndexedDB (a tiny `meta` record) so subsequent sessions know whether
+to auto-load. `.vrs` import/export is always available regardless of the opt-in flag.
+Reason: Q8-revised Option 4 — explicit user consent; trainers / privacy-conscious users
+can use file-only persistence; demo users skip persistence entirely.
+
+## D3. Multi-outcome validation
+
+`validateData()` today validates one outcome column. Slice 1 supports multiple outcomes
+per Hub (`OutcomeSpec[]`). Refactor `validateData()` to take `outcomeColumns: string[]`
+and produce a per-outcome quality report. Backward-compatible single-outcome call site
+in dashboard / analysis can wrap with `validateData(data, [singleOutcome])` and unwrap
+the first entry. Reason: V1 supports multiple outcomes per spec §3.2.
+
+## D4. Goal-context biasing — keyword extraction is deterministic
+
+`detectColumns()` gains an optional `goalContext: string` parameter. Implementation:
+extract content words from the goal narrative (lowercase, drop stopwords using
+`packages/core/src/parser/stopwords.ts` — create if missing); compute outcome candidate
+keyword-match score = max(token overlap with column name lowercased + token overlap
+with column-name's underscore-split parts). Bias is additive on top of the existing
+keyword-detection score; no replacement. Reason: deterministic per Q5 (no AI in V1);
+existing detection logic preserved.
+
+## D5. Mode A.1 reopen UX (PWA)
+
+PWA Mode A.1 reopen path: on app load, check if `hubRepository.getOptInFlag()` is true.
+If true: load saved Hub via `hubRepository.loadHub()` and render canvas with restored
+state. If false: render `HomeScreen` (existing flow). No "Hub list" UI in PWA — single
+Hub-of-one constraint per Q8. User can clear via "Forget this browser" affordance
+(separate task — not in slice 1; user can clear browser storage manually until then).
+Reason: Q8 + minimal slice 1 surface area.

+# Framing Layer V1 Slice 1 — Foundation
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use `superpowers:subagent-driven-development` (recommended) or `superpowers:executing-plans` to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Ship the smallest meaningful end-to-end framing-layer experience: a user (Mode B) can paste a CSV → state a process goal → confirm outcome(s) + (optional) specs + primary scope dimensions → land on the canvas with a goal banner + outcome pin; can opt in to "Save to this browser" for IndexedDB persistence; can export/import `.vrs` files; on PWA reopen with persistence opted in OR on Azure reopen always (Mode A.1), the canvas restores to the saved state.
+
+**Architecture:** Hub-level primitives (process goal narrative, outcome list with specs, primary scope dimensions) extend the existing `ProcessHub` type. Stage 1 (goal narrative form with scaffold chips) and Stage 3 (outcome confirmation with inline specs per candidate + scope dimensions sub-step + graceful degradation banner) are new UI components added to the entry-to-canvas pathway. Goal context biases the existing `detectColumns()` ranking via a new optional parameter. PWA gains a Dexie schema with a single Hub table (loaded only after explicit user opt-in via "Save to this browser"); `.vrs` export/import is a serializer to/from a JSON file format. The canvas first paint shows a `GoalBanner` above and an `OutcomePin` at the right edge with specs / fallback chip. Trainers can use `.vrs` export to package datasets + Hub state for students.
+
+**Tech Stack:** TypeScript + React + Vite + Vitest + Testing Library + Playwright (E2E) · Zustand (Azure stores) + React Context (PWA) · Dexie 4.x (existing in Azure, new in PWA) · pnpm + turbo monorepo · existing primitives (`detectColumns`, `inferMode`, `validateData`, `SpecEditor`, `InlineSpecEditor`, `ProcessMapBase`, `ProcessHealthBar`).
+

+
+## Slice Scope
+
+### In scope (V1 slice 1)
+
+- Mode B Stages 1–3 + canvas first paint (PWA + Azure)
+- Mode A.1 reopen (Azure always; PWA only if user opted in to persistence)
+- PWA opt-in IndexedDB persistence (single Hub-of-one) — Q8-revised Option 4
+- PWA `.vrs` file export/import (manual save/load + trainer scenario sharing)
+- Azure ProcessHub schema extension to hold framing-layer fields
+- `ProcessHub.processGoal`, `ProcessHub.outcomes[]`, `ProcessHub.primaryScopeDimensions[]` schema
+- Goal-context biased outcome detection (extend `detectColumns()`)
+- Multi-outcome validation (`validateData()` refactor)
+- Inline per-candidate spec editor at Stage 3 (no σ-based suggestions)
+- Characteristic-type-aware spec defaults
+- Primary scope dimensions auto-suggest + multi-select
+- Graceful degradation banner (no goal-keyword match)
+
+### Out of scope (later slices)
+
+- **Slice 2:** Stage 5 investigation entry modal (full implementation) + Mode A.2-paste (match-summary card with two-axis classifier) + Mode A.2-evidence-source background ingestion (Azure)
+- **Slice 3:** Multi-source via shared keys (join detection + per-source provenance)
+- **Slice 4:** Defect anchoring + Pareto on canvas (per-step mini + system) + two pickers + canvas-wide scope filter
+- **Spec 2 (separate plan):** Manual canvas authoring (drag-to-connect, sub-step grouping, branch/join)
+- **Spec 5 (separate plan):** Full IndexedDB schema for snapshots / investigations / findings (this slice only persists Hub-level state)
+
+---
+
+## Branching + Workflow
+
+- **Branch:** `framing-layer-v1-slice-1`
+- **Each task is one or more commits** on the branch (small, reviewable, TDD).
+- **Pre-merge:** `bash scripts/pr-ready-check.sh` green (tests + lint + docs:check + dist-integrity).
+- **Code review:** subagent-driven per-task review + final reviewer pass at the end (per `feedback_subagent_driven_default`).
+- **Merge:** squash-merge to `main` after final reviewer approves.
+- **Sonnet workhorse for ≥70% of dispatches** (implementer + per-task spec / quality reviewers); Opus only for final-branch review (per `feedback_subagent_driven_default`).
+- **Do not skip hooks** (no `--no-verify` per `feedback_subagent_no_verify`).
+- **Drive-by drift:** if a Task touches a file with stale TS errors / lint issues, fix in same commit per `feedback_no_backcompat_clean_architecture`.

+
+**Files:**
+
+- Create: `docs/superpowers/plans/2026-05-03-framing-layer-v1-slice-1-decisions.md`
+
+Five load-bearing decisions surfaced during plan drafting that need explicit anchors before implementation. Capture them in a companion file the implementing engineer can read alongside the plan.
+

+title: Framing Layer V1 Slice 1 — Locked Decisions
+audience: [engineer]
+category: implementation
+status: draft
+date: 2026-05-03
+related:
+
+- docs/superpowers/plans/2026-05-03-framing-layer-v1-slice-1.md

+
+# Locked Decisions — Slice 1
+
+## D1. AnalysisBrief vs new types
+
+The existing `AnalysisBrief` interface in `packages/ui/src/components/ColumnMapping/index.tsx`
+sketched issue/questions/targetMetric but is unused today. **Decision:** do NOT extend
+AnalysisBrief. Create a clean `OutcomeSpec` type on `ProcessHub`. AnalysisBrief stays in
+its current sketched form for slice 5 (Stage 5 investigation entry); slice 1 leaves it
+alone. Reason: the framing-layer spec separates Hub-level (durable: outcomes + specs)
+from investigation-level (episodic: issue + question); conflating into AnalysisBrief
+re-merges what the spec just split.
+
+## D2. PWA persistence is OPT-IN per Q8-revised
+
+PWA persists ONLY after the user clicks "Save to this browser." Default is session-only
+(matches today's behavior). The Dexie schema is loaded post-opt-in only. The opt-in flag
+itself is stored in IndexedDB (a tiny `meta` record) so subsequent sessions know whether
+to auto-load. `.vrs` import/export is always available regardless of the opt-in flag.
+Reason: Q8-revised Option 4 — explicit user consent; trainers / privacy-conscious users
+can use file-only persistence; demo users skip persistence entirely.
+
+## D3. Multi-outcome validation
+
+`validateData()` today validates one outcome column. Slice 1 supports multiple outcomes
+per Hub (`OutcomeSpec[]`). Refactor `validateData()` to take `outcomeColumns: string[]`
+and produce a per-outcome quality report. Backward-compatible single-outcome call site
+in dashboard / analysis can wrap with `validateData(data, [singleOutcome])` and unwrap
+the first entry. Reason: V1 supports multiple outcomes per spec §3.2.
+
+## D4. Goal-context biasing — keyword extraction is deterministic
+
+`detectColumns()` gains an optional `goalContext: string` parameter. Implementation:
+extract content words from the goal narrative (lowercase, drop stopwords using
+`packages/core/src/parser/stopwords.ts` — create if missing); compute outcome candidate
+keyword-match score = max(token overlap with column name lowercased + token overlap
+with column-name's underscore-split parts). Bias is additive on top of the existing
+keyword-detection score; no replacement. Reason: deterministic per Q5 (no AI in V1);
+existing detection logic preserved.
+
+## D5. Mode A.1 reopen UX (PWA)
+
+PWA Mode A.1 reopen path: on app load, check if `hubRepository.getOptInFlag()` is true.
+If true: load saved Hub via `hubRepository.loadHub()` and render canvas with restored
+state. If false: render `HomeScreen` (existing flow). No "Hub list" UI in PWA — single
+Hub-of-one constraint per Q8. User can clear via "Forget this browser" affordance
+(separate task — not in slice 1; user can clear browser storage manually until then).
+Reason: Q8 + minimal slice 1 surface area.
+```

+D2: PWA persistence opt-in via 'Save to this browser'

+D4: Goal-context biasing is deterministic keyword extraction

+## Task 1: ProcessHub schema extension — add framing-layer fields
+
+**Files:**
+
+- Modify: `packages/core/src/processHub.ts` (around line 54 where `ProcessHub` is defined; add new fields after `contextColumns`)
+- Create: `packages/core/src/processHub/__tests__/processHubFields.test.ts`
+
+- [ ] **Step 1.1: Write failing test**
+
+```typescript
+// packages/core/src/processHub/__tests__/processHubFields.test.ts
+import { describe, expect, it } from 'vitest';
+import type { ProcessHub, OutcomeSpec } from '../../processHub';
+import { DEFAULT_PROCESS_HUB } from '../../processHub';

+  });
+
+  it('accepts a list of outcome specs', () => {

+      lsl: 4.2,
+      usl: 4.8,
+      cpkTarget: 1.33,
+    };
+    const hub: ProcessHub = { ...DEFAULT_PROCESS_HUB, outcomes: [outcome] };

+    expect(hub.outcomes).toBeUndefined();
+    expect(hub.primaryScopeDimensions).toBeUndefined();
+  });
+});
+```
+
+- [ ] **Step 1.2: Run test to verify it fails**
+
+```bash
+pnpm --filter @variscout/core test processHubFields
+```
+
+Expected: FAIL — `OutcomeSpec` not exported.
+
+- [ ] **Step 1.3: Implement schema changes**
+
+Edit `packages/core/src/processHub.ts`. After the existing `ProcessParticipantRef` type and before `ProcessHub`, add:
+
+```typescript
+export type CharacteristicType = 'nominalIsBest' | 'smallerIsBetter' | 'largerIsBetter';
+
+export interface OutcomeSpec {
+  /** Column name from the dataset that quantifies delivery on the goal. */
+  columnName: string;
+  /** Characteristic type — drives spec input UI (nominal disables nothing; smaller-is-better disables LSL; larger-is-better disables USL). */
+  characteristicType: CharacteristicType;
+  /** Target value. Customer-driven; UI may suggest dataset mean for nominal-is-best as a starting point. */
+  target?: number;
+  /** Lower spec limit. Customer-driven (no σ-based suggestions). N/A for smaller-is-better. */
+  lsl?: number;
+  /** Upper spec limit. Customer-driven (no σ-based suggestions). N/A for larger-is-better. */
+  usl?: number;
+  /** Cpk target. Defaults to 1.33 (literature standard). */
+  cpkTarget?: number;
+}
+```
+
+Then in the `ProcessHub` interface, add three optional fields after `contextColumns`:
+
+```typescript
+  /** Process goal narrative (Hub-level, durable). One paragraph; 1–5 sentences typical. */
+  processGoal?: string;
+  /** Outcome columns and their specs. Multiple outcomes supported per Hub. */
+  outcomes?: OutcomeSpec[];
+  /** Discrete columns the analyst slices analysis by most often. Marked dimensions get prominent picker access. */
+  primaryScopeDimensions?: string[];
+```
+
+- [ ] **Step 1.4: Run test to verify it passes**
+
+```bash
+pnpm --filter @variscout/core test processHubFields
+```
+
+Expected: PASS — 4 tests.
+
+- [ ] **Step 1.5: Run package build to verify type exports**
+
+```bash
+pnpm --filter @variscout/core build
+```
+
+Expected: PASS — no TS errors.
+
+- [ ] **Step 1.6: Commit**
+
+```bash
+git add packages/core/src/processHub.ts packages/core/src/processHub/__tests__/
+git commit -m "feat(core): add framing-layer fields to ProcessHub
+
+processGoal: string narrative (Hub-level durable)
+outcomes: OutcomeSpec[] (CTQs in plain language)
+primaryScopeDimensions: string[] (prominent picker dimensions)
+
+OutcomeSpec includes characteristicType (nominalIsBest /
+smallerIsBetter / largerIsBetter) — drives spec-input UI per
+framing-layer spec §5.3. Specs are customer-driven; no σ-based
+suggestions per Q8 / spec §3.3."

+
+New PwaDatabase (Dexie v1) with two tables: hubs (single-row

+
+hubRepository API: getOptInFlag / setOptInFlag (auto-clears
+Hub on false) / saveHub (overwrites single row) / loadHub
+(returns null if absent) / clearHub.

+Per Q8-revised: Dexie loaded only after explicit opt-in via
+'Save to this browser' affordance (Task 13). Default behavior
+unchanged from today (session-only). dexie + fake-indexeddb

+interface SessionState {

+export function useSession(): SessionStore {
+  const ctx = useContext(SessionContext);
+  if (!ctx) throw new Error('useSession must be used within SessionProvider');
+  return ctx;
+}
+```
+
+- [ ] **Step 14.5: Wire App.tsx routing**
+
+In `apps/pwa/src/App.tsx`:
+
+1. Wrap the app tree in `<SessionProvider>`.
+2. On app load (`useEffect`), call `hubRepository.getOptInFlag()`. If true, `hubRepository.loadHub()` → `setHub(loaded)`.
+3. Route logic:
+   - If `hub === null && rawData === null` → `<HomeScreen />`
+   - After paste → render `<HubGoalForm onConfirm={(narrative) => navigateTo('column-mapping', narrative)} />`
+   - After goal → render `<ColumnMapping {...} />` refactored to use `OutcomeCandidateRow`, `PrimaryScopeDimensionsSelector`, `OutcomeNoMatchBanner`.
+   - After confirm → build Hub, call `setHub(builtHub)`, route to `<Dashboard />` with `<GoalBanner goal={hub.processGoal} />` and `<OutcomePin />` for each outcome.
+
+Pseudocode (skeleton — full integration with existing PWA flow):
+
+```typescript

+  return <CanvasView hub={hub!} rawData={rawData!} />;
+}
+
+function CanvasView({ hub, rawData }: { hub: ProcessHub; rawData: Array<Record<string, unknown>> }) {
+  // Compute stats per outcome
+  return (
+    <div>
+      <GoalBanner goal={hub.processGoal} />
+      {hub.outcomes?.map((o) => (
+        <OutcomePin
+          key={o.columnName}
+          outcome={o}
+          stats={computeStats(rawData, o.columnName)}
+          onAddSpecs={(col) => {/* open SpecEditor */}}

+
+export default function App() {
+  return (
+    <SessionProvider>
+      <AppRoutes />
+    </SessionProvider>

+- [ ] **Step 15.2: Run test to verify it fails**
+
+```bash
+pnpm --filter @variscout/azure-app test HubCreationFlow
+```
+
+Expected: FAIL — module not found.
+
+- [ ] **Step 15.3: Implement HubCreationFlow**
+
+```typescript

+```
+
+- [ ] **Step 15.4: Wire Dashboard "+ New Hub" button**
+
+In `apps/azure/src/pages/Dashboard.tsx`:
+
+```typescript
+import { HubCreationFlow } from '../components/editor/HubCreationFlow';
+import { saveProcessHub } from '../services/processHubService'; // existing
+
+// In the Dashboard component:
+const [creating, setCreating] = useState(false);
+
+return (
+  <>
+    {/* existing Hub list UI */}
+    <button onClick={() => setCreating(true)}>+ New Hub</button>
+    {creating && (
+      <HubCreationFlow
+        onCreated={async (hub, rawData) => {
+          await saveProcessHub(hub);
+          // Optionally: persist initial rawData as the first snapshot here (slice 2 expansion)
+          setCreating(false);
+          setSelectedHubId(hub.id);
+        }}
+        onCancel={() => setCreating(false)}
+      />
+    )}
+  </>
+);
+```
+
+- [ ] **Step 15.5: Mount GoalBanner above ProcessHubView tabs**
+
+In `apps/azure/src/components/ProcessHubView.tsx`, wrap the existing tab container in a `<GoalBanner goal={hub.processGoal} onChange={(next) => updateHub({ ...hub, processGoal: next })} />` block at the top.
+
+- [ ] **Step 15.6: Bump Dexie schema version 4 → 5 (no-op migration)**
+
+In `apps/azure/src/db/schema.ts`, after the existing `this.version(4).stores({...})` chain, add:
+
+```typescript
+this.version(5).stores({
+  // No schema changes — new fields (processGoal, outcomes, primaryScopeDimensions)
+  // are TypeScript-only on ProcessHub; Dexie stores objects without enforcing
+  // structure. Bumping the version flushes any cached schema and is harmless
+  // for existing rows (their JSON simply lacks the new fields, which read as
+  // undefined per the optional types).
+});
+```
+
+- [ ] **Step 15.7: Run all related tests**
+
+```bash
+pnpm --filter @variscout/azure-app test HubCreationFlow
+pnpm --filter @variscout/azure-app test ProcessHubView
+```
+
+Expected: PASS — new tests pass; existing ProcessHubView tests still pass (the GoalBanner is purely additive).
+
+- [ ] **Step 15.8: Commit**
+
+```bash
+git add apps/azure/src/components/editor/HubCreationFlow.tsx \
+        apps/azure/src/components/editor/__tests__/ \
+        apps/azure/src/pages/Dashboard.tsx \

+git commit -m "feat(azure): Mode B end-to-end wiring + ProcessHub schema migration v5
+
+HubCreationFlow component (Stage 1 → Stage 2 → Stage 3 → built
+Hub) reuses framing-layer primitives from @variscout/ui +
+@variscout/core (HubGoalForm, OutcomeCandidateRow,

+
+Dashboard '+ New Hub' button routes through HubCreationFlow
+and persists via saveProcessHub. ProcessHubView mounts
+GoalBanner above the existing Status/Capability tabs (Mode A.1
+reopen — Hub state restored from Dexie always; Azure tier has
+no opt-in flag).
+
+Dexie schema v5 is a no-op version bump; the new ProcessHub
+fields are optional TypeScript additions that Dexie stores
+without schema migration."

+### Task 16: Spec status update + decision-log session backlog entry
+
+**Files:**
+
+- Modify: `docs/superpowers/specs/2026-05-03-framing-layer-design.md` (frontmatter `status: draft` → `active`)
+- Modify: `docs/decision-log.md` (§4 Session Backlog: add a row "Framing Layer V1 Slice 1" → in-flight → done with PR link)
+
+This task is the slice-exit ceremony.
+
+- [ ] **Step 16.1: Update spec status**
+
+In `docs/superpowers/specs/2026-05-03-framing-layer-design.md` frontmatter:
+
+```diff

+```
+
+- [ ] **Step 16.2: Add session backlog entry**
+
+In `docs/decision-log.md` §4 Session Backlog table:
+
+```markdown
+| Framing Layer V1 Slice 1 implementation | implementation | done | docs/superpowers/plans/2026-05-03-framing-layer-v1-slice-1.md | 2026-05-03 | <PR-merge-date> |

+
+---
+
+## Self-Review Checklist
+
+Run before requesting final review:
+
+- [ ] All tasks have concrete `Files: Create/Modify/Test` lines
+- [ ] No `TBD` / `TODO` / `fill in later` placeholders in any task body
+- [ ] Each TDD step shows actual code (not "write a test for X")
+- [ ] Type names consistent across tasks (e.g., `OutcomeSpec` defined in Task 1 used unchanged in Tasks 5–16)
+- [ ] Commit messages follow project conventions (feat / refactor / docs / chore prefixes)
+- [ ] No σ-based suggestions for LSL/USL anywhere in code (Q8 / Q2 invariant)
+- [ ] PWA persistence is opt-in only (Q8-revised)
+- [ ] `.vrs` round-trip tested (Task 11)
+- [ ] Goal-context biasing is deterministic (Task 3 — no AI per Q5)
+- [ ] Multi-outcome supported throughout (Task 4 — spec §3.2)
+- [ ] All new components have tests
+- [ ] CI guards: search for any new code violating ADR-073 structural absence — there should be none in slice 1 (no aggregation primitives introduced)
+
+---
+
+## Slice Exit Criteria
+
+V1 slice 1 is complete when:
+
+- [ ] All 16 tasks land on `framing-layer-v1-slice-1` branch with green CI
+- [ ] `bash scripts/pr-ready-check.sh` passes
+- [ ] PWA Playwright E2E test for Mode B passes end-to-end
+- [ ] Azure equivalent test passes (RTL or E2E, whichever is faster to write)
+- [ ] PWA `.vrs` export-import round-trip works in browser (manual smoke test)
+- [ ] PWA "Save to this browser" persists Hub across page reload (manual smoke test)
+- [ ] Azure existing tests all pass (no regression on shipped Hub functionality)
+- [ ] `docs:check` green
+- [ ] Final code-reviewer subagent (Opus) approves the branch
+- [ ] Squash-merge to main; spec status flipped to `active`; decision-log entry closed
+
+---
+
+## Next Slice Preview
+
+**V1 slice 2 — Mode A.2-paste data ingestion**
+
+Scope: match-summary card with 2-axis classifier (source × temporal), block-on-overlap and block-on-different-grain action choices, per-row provenance fields, A.2-evidence-source background ingestion (Azure-only).
+
+File touch: new `MatchSummaryCard` component, extension to `suggestNodeMappings` reuse, provenance schema in `ProcessHub.snapshots[]`, Azure background job for Evidence Source ingestion.
+
+Plan to be written after slice 1 lands.

+# VariScout Framing Layer
+
+> **First of five canvas-detail specs** decomposed from the 2026-05-03 vision §8 walkthrough. Covers Hub creation, data ingestion, and investigation entry — everything _before_ canvas authoring proper. Inherits the 12 locked decisions from the §8 resolution. Sibling specs (deferred): Spec 2 manual canvas authoring, Spec 3 cards / drill-down / mode lenses, Spec 4 canvas overlays + Wall sync, Spec 5 IndexedDB persistence schema.
+
+## 1. Context
+
+The 2026-05-03 vision spec commits to a unified Canvas that absorbs the Frame and Analysis tabs (Q0). What it doesn't detail is _how data and analyst intent enter the canvas_ — the entry-to-canvas pathway. This spec fills that gap.
+
+Two things drive the design:
+
+1. **The mental model the analyst should develop over years of usage.** Watson's three questions ("what's happening / what does it cost / what do we want") lifted into the product structure. The analyst's reflexive starting point becomes "why does this process exist?", "how is it doing against that purpose?", "where is it deviating?" — not "I have data, what does it tell me?"
+2. **Reality of multi-source factory data.** Production telemetry, QC inspection, maintenance logs come from different upstream systems on different cadences. They join via shared identifiers (`lot_id` / `batch_id` / `part_id`). Treating each source as a separate Hub loses methodological coherence. The Hub spine is the process line; data flows in from multiple sources via join keys.
+
+The spec describes the complete framing-layer design. V1/V2 partitioning at §15 is _delivery phasing_, not design phasing (per `feedback_full_vision_spec`).
+
+### What this spec covers
+
+- The two-layer model (Hub-level durable + investigation-level episodic)
+- Hub-level primitives: process goal, outcome measures, specs, primary scope dimensions
+- Investigation-level grammar: Issue → Question → Hypothesis (CTP→CTQ) → Evidence → Finding
+- Mode B (first-time Hub creation) — Stages 1–5
+- Mode A (reopening existing Hub) — three sub-cases including paste-driven match and Evidence Source auto-ingestion
+- Match-summary card with two-axis classifier (source × temporal)
+- Multi-source ingestion via shared keys
+- Defect data anchoring and Pareto integration on the canvas
+- Three composable canvas filter states (time window / scope / Pareto group-by)
+- Graceful degradation when detection fails
+
+### What this spec does NOT cover (sibling specs)
+
+- Manual canvas authoring (drag-to-connect, sub-step grouping, branch/join) — Spec 2
+- Step card details, drill-down floating overlay UX, mode-lens reskinning — Spec 3
+- Canvas overlays (investigations / hypotheses / suspected causes / findings) and Wall projection sync — Spec 4
+- IndexedDB persistence schema for PWA Hub-of-one — Spec 5
+
+This spec ends at _"canvas first paint with goal banner + outcome pin"_ (Mode B) or _"canvas with restored state + new-snapshot indicator"_ (Mode A). What happens _on_ the canvas is downstream.
+
+## 2. The two-layer model
+
+VariScout's framing has two layers with different durability and cognitive shape:
+
+| Layer                   | Durability                                          | Cognitive shape                                      | Where it lives       |
+| ----------------------- | --------------------------------------------------- | ---------------------------------------------------- | -------------------- |
+| **Hub-level**           | Persistent across investigations / sessions / years | Authored once at Hub creation; refined incrementally | Hub config           |
+| **Investigation-level** | Per-session; comes and goes                         | Episodic; "what's deviating today?"                  | Investigation entity |
+
+The Hub layer teaches the methodology habit. Every time the analyst opens or creates a Hub, they engage with "why does this process exist?" — Watson VOC at the door of the product. The investigation layer is where today's deviation gets investigated against the durable goal.
+
+After 6+ months of use, the analyst's reflex becomes:
+
+1. **Why does this process exist?** _(Hub-level, durable)_
+2. **How is it doing against that purpose right now?** _(cadence read on the canvas)_
+3. **Where is it deviating?** _(drill-down + 5 response paths, vision §2.4)_
+4. **Is the deviation explained?** _(investigation graph)_
+5. **Did our action close the gap?** _(sustainment)_
+
+This is a far better operator habit than "I have data; what does it tell me?" — which is what most data-first tools teach.
+
+## 3. Hub-level primitives
+
+A Process Hub holds these durable artifacts. The first three are authored at Hub creation; the fourth and fifth grow incrementally.
+
+### 3.1 Process goal
+
+A short narrative covering: **purpose** (what does this process produce?), **customer** (for whom?), and **what matters** about the output. One paragraph; 1–5 sentences typical.
+
+The narrative implicitly carries the methodological CTS (customer-language expectation). It is **not** broken into separate fields — the goal sentence holds them together. Watson's three Qs survive as scaffolding, not as form fields (§5.1).
+
+The goal also seeds:
+
+- **Hub name** — auto-extracted from the first sentence (editable). e.g., "Syringe-barrel injection line."
+- **Outcome detection bias** — keywords from the goal narrative bias the deterministic detection at Stage 3.
+- **CoScout coaching anchor** (Azure tier) — feeds tier1 prompt context per ADR-068 amendment.
+
+### 3.2 Outcome measure(s)
+
+One or more columns from the dataset that quantify delivery on the goal. Plain-language label is **"outcome"** — the methodological concept is CTQ, but the acronym is retired user-facing per vision §3.3 commitment 9 (see `docs/glossary.md` retired-terms section).
+
+Multiple outcomes are supported: a Hub can have both `weight_g` (continuous, dimensional) and `defect_count` (discrete, count) as outcomes simultaneously. Each outcome is independently:
+
+- Pinned at the right edge of the canvas
+- Tied to its own specs (§3.3)
+- Capable of receiving its own drill-down
+
+### 3.3 Specs per outcome
+
+For each outcome column: **target**, **LSL**, **USL**, **cpkTarget**. These are _customer-driven_ values from the quality contract / drawing tolerances / regulatory limits — not derived from the data's variability.
+
+VariScout does **not** suggest LSL/USL based on `target ± 3σ`. Such suggestions silently teach the wrong mental model — they conflate spec limits (customer requirement) with control limits (process behavior). The two are different concepts; the glossary documents the distinction. Spec inputs are placeholders ("from customer spec") or empty by default.
+
+What VariScout _does_ offer:
+
+- **Target suggestion** = dataset mean for nominal-is-best characteristic type, with a clear hint "starting point — replace with customer target"
+- **Smart defaults adapt to characteristic type**: smaller-is-better disables LSL; larger-is-better disables USL
+- **`cpkTarget` default = 1.33** (literature standard, customer-overridable)
+
+Specs are **optional at Hub creation**. The skip-spec path falls through to the canvas's outcome-pin fallback rule (per Q2): outcome card swaps the Cpk badge for `mean ± σ + n` and shows a `+ Add specs` chip until specs are added. Methodology habit preserved without front-loading numeric inputs.
+
+### 3.4 Primary scope dimensions
+
+Discrete columns the analyst will slice analysis by most often: typically 2–4 columns out of 10–30. Examples: `product_id`, `lot_id`, `shift`, `machine_id`, `supplier`.
+
+Marked dimensions get prominent picker access across the canvas:
+
+- Pareto group-by dropdown shows them at the top
+- Canvas filter chips offer one-click "Filter by [primary dim]"
+- Drill-down panel uses them as default filter axes
+
+VariScout suggests dimensions based on column cardinality (3–50 levels typical) plus name heuristics (`*_id`, `lot`, `batch`, `product`, `customer`, `shift`, `operator`, `machine`, `supplier`). User confirms or overrides. Skippable — system falls back to first-name-keyword-match plus cardinality.
+
+High-cardinality columns (e.g., `batch_id` with 412 levels) are flagged as "join keys, not Pareto candidates" — they make poor Pareto X-axes but valuable join keys.
+
+### 3.5 ProcessMap structure
+
+The DAG of steps + sub-steps + arrows + branches/joins is a Hub-level primitive but its design lives in **Spec 2 (manual canvas authoring)**. Spec 1 doesn't author the map; it ensures the entry-to-canvas pathway delivers the user to a canvas where Spec 2 takes over.
+
+For Spec 1 purposes: the ProcessMap exists in the data model (per vision §3.3 ten commitments), and Mode A reopen restores it from persistence.
+
+## 4. Investigation-level grammar
+
+When an analyst opens an investigation on a Hub that has its goal + outcomes defined, every session follows the same shape:
+
+```
+ISSUE          →   QUESTION         →   HYPOTHESIS              →   EVIDENCE         →   FINDING
+"what's            "what would          CTP → CTQ relationship       statistical           what the
+happening"         tell us?"           ("a change in factor X         tests on              evidence shows
+                                        caused a shift in Y")         canvas data
+```
+
+The hypothesis shape — **"a change in [process input] caused a shift in [outcome]"** — is exactly how factory-floor investigations look. It maps directly to existing entities in code:
+
+| Conceptual primitive          | Existing entity / file                                                     |
+| ----------------------------- | -------------------------------------------------------------------------- |
+| Issue statement               | `ProcessContext` / Issue Statement (`project_problem_statement` in memory) |
+| Question                      | `Question` entity in `investigationStore`                                  |
+| Hypothesis (CTP→CTQ)          | `SuspectedCause` hub (ADR-064) + `CausalLink` (`fromFactor → toFactor`)    |
+| Evidence                      | Findings linked to charts via `buildFindingSource`                         |
+| Finding                       | `Finding` entity in `useFindingStore`                                      |
+| Promoted hypothesis on canvas | Q11 node marker (when evidence crossed threshold)                          |
+
+This isn't new infrastructure — it's connecting infrastructure that already exists with a coherent grammar instead of three disconnected entry points.
+
+The vocabulary `CTP` and `CTQ` survives in **CoScout methodology coaching** (where teaching the language is the point, Azure tier) but not in user-facing primitives. User-facing labels are _input_ / _factor_ / _outcome_ per glossary canonicalization.
+
+## 5. Mode B — first-time Hub creation
+
+Five stages. Stages 1–3 set up the Hub (durable). Stage 4 = canvas authoring (Spec 2). Stage 5 = investigation entry (episodic, optional).
+
+### 5.1 Stage 1 — Process goal narrative
+
+A textarea labeled "Why does this process exist?" with three **scaffold chips** above it:
+
+- `+ Purpose`
+- `+ Customer`
+- `+ What matters`
+
+Clicking a chip inserts a labeled prompt chunk into the textarea (e.g., `Purpose: ` followed by cursor) — the user fills in. Chips are optional; the textarea accepts free-form prose without using them. This balances Mode B friction (one line gets you through) with methodology scaffolding (the chips teach the Watson VOC habit by example).
+
+A "See examples" link surfaces 2–3 anonymized goal narratives (syringe-barrel / baker / assembly station) for first-time users who'd benefit from priors.
+
+**Hub name** auto-extracts from the first sentence after Continue. Editable inline at any time.
+
+**Skip path:** "Skip framing (advanced)" link for power users who want to land on the canvas immediately. Skipped Hubs use the dataset filename as the Hub name and have no goal narrative until later edited.
+
+### 5.2 Stage 2 — Paste / upload data
+
+Existing UX preserved (`PasteScreen`, drop zone, sample dataset chips). Detection runs with goal context: keywords from the Stage 1 narrative bias the outcome ranking at Stage 3.
+
+### 5.3 Stage 3 — Outcome confirmation, specs, scope dimensions
+
+Three sub-concerns on one screen, ordered by importance:
+
+#### 5.3.1 Outcome confirmation
+
+One row per candidate column, horizontal layout:
+
+`[radio] [name + type] [sparkline] [inline spec inputs (when selected)] [data quality stack] [match confidence]`
+
+Specs appear inline only on **selected** candidates. Multi-select supported (a Hub can have multiple outcomes). Smart spec defaults adapt to characteristic type (nominal-best / smaller-best / larger-best). LSL/USL placeholders say "from customer spec" — no σ-based suggestions.
+
+Each row shows:
+
+- **Sparkline** (mini histogram) — distribution shape at a glance
+- **Data quality** — inline `n=` count, `% missing`, NaN/Inf flags from `validateData()` / `DataQualityReport` (ADR-069 B1)
+- **Match confidence** — % keyword match against the goal narrative + bonus from name patterns (`weight`, `defect`, `cycle_time`, `quality`, etc.)
+
+Skip-specs path: confirms the outcome but defers spec entry to the canvas (Q2 fallback rule).
+
+#### 5.3.2 Primary scope dimensions sub-step
+
+After outcome confirmation, a small expandable section: "Which columns will you slice analysis by most often?" (§3.4). System pre-checks suggested dimensions based on cardinality + name heuristics; user confirms or overrides. Skippable.
+
+#### 5.3.3 Graceful degradation when no outcome candidate has goal-keyword match
+
+Trigger: vague goal narrative OR cryptic column names (`Var1`, `X23`, `Quality`). All candidates score below ~30% match.
+
+UX:
+
+- Banner: "No clear outcome match. Either rename a column to match your outcome (best for the long term) or pick manually below."
+- Inline rename affordance (✎ icon) next to each column name
+- Free-text "I expected the outcome to be: \_\_\_" note
+- Skip-outcome path: canvas paints with all columns unclassified; user assigns roles via the canvas later
+- Hub records the user's pick — future paste of a column with this name will rank higher (deterministic learning, no AI required)
+
+### 5.4 Stage 4 — Canvas first paint (Spec 2 territory)
+
+The framing-layer spec ends here. Stage 4 transitions to the canvas with:
+
+- **Goal banner** at the top of the canvas (auto-extracted from goal narrative)
+- **Outcome pin** at the right edge with confirmed outcome columns + their specs (or fallback)
+- **Auto-classified factor / metadata chips** waiting to be placed on steps (Spec 2 details the placement UX)
+
+### 5.5 Stage 5 — Investigation entry (optional, floating modal)
+
+Form factor: **floating modal** over the canvas, consistent with Q1 drill-down overlay. Same modal shape, different content.
+
+Fields:
+
+- **Issue** (free-text) — what's happening, what just changed
+- **Question** (free-text) — what would tell us?
+- **Hypothesis** (optional) — pin on canvas later if skipped here
+
+Two buttons:
+
+- **"Open investigation →"** opens the Investigation tab with the active context
+- **"Skip — explore canvas instead"** lands on the canvas with no active investigation context (observation-triggered EDA per Constitution P5)
+
+The three Constitution P5 entry points map cleanly:
+
+| Entry point           | Stage 5 path                                                                                |
+| --------------------- | ------------------------------------------------------------------------------------------- |
+| Upfront hypothesis    | Fill the framing card → investigation opened with hypothesis pinned                         |
+| Evidence-ranked       | Fill issue + question → investigation opened, hypothesis discovered via Factor Intelligence |
+| Observation-triggered | Skip → canvas → discover something → `QuestionLinkPrompt` formalizes retroactively          |
+
+In Mode A (cadence), Stage 5 opens on demand via a "+ New investigation" button in the canvas chrome. The same modal serves both modes.
+
+## 6. Mode A — reopening an existing Hub
+
+Three sub-cases. The Hub already has goal + outcomes + specs + scope dimensions; Stages 1–3 are bypassed.
+
+### 6.1 A.1 — Reopen, no new data
+
+User clicks Hub from the Hub list. Hub state restored to the canvas. Latest snapshot's capability badges + drift indicators visible. Stage 5 modal opens on demand via "+ New investigation" button.
+
+### 6.2 A.2-paste — Reopen + manual paste
+
+User pastes a new CSV onto the canvas (or via "Paste new snapshot" affordance). System runs the **match-summary card** (§7) classifying the paste along source and temporal axes. User confirms an action; canvas updates with the new snapshot.
+
+### 6.3 A.2-evidence-source — Auto-ingestion (Azure only)
+
+Cadence-driven Evidence Source (Blob Storage push or scheduled pull) lands a new snapshot while the user is offline. Background job runs match logic. PWA Hub-of-one has no cloud sync per Q8 — A.2-evidence-source is Azure-tier only.
+
+What the user sees on next open:
+
+- **"X new snapshots ↑"** chip in the goal banner
+- Snapshot timeline strip on the canvas chrome highlights new snapshots in green
+- Cpk drift indicator updates to reflect new data
+- If column drift was detected during background ingestion, a one-line yellow banner: "Snapshot S26 had a new column `defect_type` — review map?"
+- Click the chip → quick "what's new" summary (capability change vs prior; column drift)
+
+## 7. Match-summary card (Mode A.2-paste)
+
+The match-summary card is the most novel surface in this spec. It opens whenever a user pastes new data into an existing Hub.
+
+### 7.1 Two-axis classifier
+
+The card classifies the paste along two independent axes:
+
+#### Source axis (where from)
+
+| Case                           | Description                                         | Default action                           |
+| ------------------------------ | --------------------------------------------------- | ---------------------------------------- |
+| 1. Same source                 | Snapshot of existing telemetry                      | Add as new snapshot                      |
+| 2. Different source · joinable | New source matching via shared key (`lot_id`, etc.) | Suggest join key; multi-source flow (§8) |
+| 3. Different source · no key   | Entirely different shape, no shared key             | Suggest creating a new Hub               |
+| 4. Mixed                       | Some columns match, some are from a new source      | Confirm column-by-column                 |
+
+#### Temporal axis (when)
+
+| Case                   | Description                                 | Default action                                                |
+| ---------------------- | ------------------------------------------- | ------------------------------------------------------------- |
+| 1. Append              | New range > existing max                    | Add as new snapshot                                           |
+| 2. Backfill            | New range < existing min                    | Add as backfill + warn drift may shift                        |
+| 3. **Overlap**         | Ranges intersect                            | **Block** — force user to choose replace / keep both / cancel |
+| 4. Replace             | ~Same range; high duplicate-row rate (>70%) | Suggest "replace this period?"                                |
+| 5. No timestamp        | No time column in dataset                   | Treat as anonymous batch with import-time                     |
+| 6. **Different grain** | Hourly raw vs daily aggregates, etc.        | **Block** — separate Hub or aggregate first                   |
+
+**Block cases** (Source #3, Temporal #3, Temporal #6) force the user to make a choice rather than silently merging incompatible data. World-class minimum: never silently double-count or merge incompatible grains. Methodology rationale: rational subgrouping (Watson) requires that pooled samples were drawn under similar conditions; silent merging of overlapping or different-grain data violates this and makes Cpk lie.
+
+### 7.2 Timeline preview
+
+The card leads with a horizontal timeline strip:
+
+- **Existing snapshots** rendered as green segments
+- **New dataset range** rendered as a blue overlay
+- **Overlap region** (if any) rendered in orange
+
+Reuses the shipped `TimelineWindow` primitive from Multi-level SCOUT V1 (per memory `project_multi_level_scout`).
+
+### 7.3 Action choices per case
+
+For block cases (overlap, different grain), the card surfaces explicit options:
+
+**Overlap:**
+
+- Replace overlap with new data (default; archives replaced rows with `replaced-by:<import-id>` tag)
+- Keep both — separate snapshots / sources (treats as different cadences)
+- Cancel and check (don't import; investigate why overlap exists)
+
+**Different grain:**
+
+- No silent default. User chooses: separate Hub / aggregate the new data first / cancel.
+
+For non-block cases, default action proceeds with single confirmation.
+
+### 7.4 Column shape sub-summary
+
+Independent of the temporal classification, the card shows column-shape match status (reuses shipped `suggestNodeMappings` engine):
+
+- **✓ matched columns** — render existing
+- **+ new columns** — user assigns role (factor / metadata / ignore) and connects to a step
+- **⚠ missing columns** — flagged as gap; doesn't block ingestion (could be sensor outage)
+
+## 8. Multi-source ingestion via shared keys
+
+Real factories have data from multiple upstream systems: production telemetry, QC inspection, MES, lab LIMS, maintenance logs. Each on its own cadence with its own time anchor. The Hub spine is the process line; sources join via shared identifiers.
+
+### 8.1 Detection
+
+Triggers when pasted data has:
+
+- Column shape significantly different from Hub map AND
+- At least one column matches a Hub column by name (or by `*_id` / `lot` / `batch` / `serial` / `part` naming heuristic)
+
+System suggests join-key candidates ranked by:
+
+- **Name match score** — column name in both Hub and pasted data
+- **Value overlap** — what % of values intersect between the two columns
+- **Cardinality compatibility** — joinable to existing data structure
+
+User confirms or picks an alternative key.
+
+### 8.2 Join semantics
+
+Once joined:
+
+- Each row is tagged with `source=<id>`
+- Hub map includes columns from both sources
+- Canvas treats joined-source columns as **context dimensions** (vision §3.3 commitment 7) — context propagates downstream just like step-of-origin propagation
+- Per-source independent timelines preserved (V1; V2 derives lot windows from telemetry per §15)
+
+### 8.3 Per-row provenance
+
+Every imported row stores:
+
+```
+source           = <A | B | C ...>           // source identifier
+origin           = <import-id>                // which paste / file / Evidence Source
+imported_at      = <wall-clock>              // when it was added to VariScout
+row_timestamp    = <from data, if present>   // original timestamp
+snapshot_id      = <Hub-assigned>            // which logical snapshot
+join_key         = <key column name>          // when joined via shared key
+```
+
+Replace-overlap actions archive replaced rows with `replaced-by:<import-id>` rather than deleting them. Provenance is recoverable.
+
+### 8.4 Methodological alignment
+
+The architecture honors:
+
+- **ADR-073 (no statistical roll-up across heterogeneous units):** multi-source data joined via key gives per-(source × key × scope) cells. The join key is the structural anchor preventing illegitimate aggregation across sources.
+- **Vision §3.3 commitment 7 (context propagation):** lot/batch/part IDs become context tuples that QC defects inherit from production telemetry.
+- **Vision §2.3 (sample-size honesty):** per-source `n` counts preserved; the canvas can show "n=1842 telemetry points · n=87 inspections per lot" — different sampling cadences made visible.
+
+Industry analogs: process mining (Celonis case ID), data warehouses (fact + dimension foreign keys), time-series + event correlation (Splunk entity ID), manufacturing analytics (PTC ThingWorx equipment ID).
+
+## 9. Defect data and Pareto integration
+
+Defect / rejection data lands on the canvas at multiple anchor points and powers a canvas-attached Pareto with two pickers.
+
+### 9.1 Defect anchoring (multi-anchor)
+
+When a dataset includes a `step_rejected_at` (or equivalent) column, defect rows anchor to specific step nodes:
+
+- **End-of-line / outcome defects** — pin at the right edge alongside the outcome
+- **Per-step rejects** — anchor to the specific step that caught them
+- **Per-lot rolled-up defects** — multi-source via `lot_id`, attribute to system or step depending on data shape
+- **Mixed** — real factories have all three at once
+
+Detection at Stage 3 (Mode B) or A.2-paste (Mode A): when defect-mode column shape detected, system asks "Which column tells you which step caught this defect?" with the column picker. Optional; default = outcome / end-of-line anchoring.
+
+### 9.2 Pareto on the canvas
+
+Per-step mini-Pareto chips appear inline on step cards that have rejection data. System Pareto card attaches to the outcome pin. Without rejection data, neither appears (canvas stays clean).
+
+The Pareto card is a first-class canvas element — visible in flow context, not buried behind a click. Click a bar → canvas-wide scope filter (§10). Multi-select for top-N investigation. **"Make this the investigation scope"** affordance promotes the selection to a Stage 5 investigation with the issue auto-filled.
+
+### 9.3 Two pickers — group-by and weighted-by
+
+The Pareto card has two independent pickers in its header:
+
+- **Group by (X axis)** — categorical dimension to bin the bars by. Available list = primary scope dimensions (top of dropdown) + any other discrete column with reasonable cardinality. Examples: `defect_type` (default in defect mode) · `product_id` · `lot_id` · `supplier` · `operator` · `shift`.
+- **Weighted by (Y axis)** — what determines bar height. Adapts to active mode lens (§9.4).
+
+### 9.4 Y axis adapts to mode lens
+
+Pareto generalizes from "defect Pareto" to a "where to focus" chart that adapts to data shape:
+
+| Mode lens         | Y axis options                                                                           |
+| ----------------- | ---------------------------------------------------------------------------------------- | ------------- | --- |
+| Defect mode       | count · time (downtime) · cost · severity-weighted (V2 — Watson G11)                     |
+| Capability mode   | % out-of-spec · Cpk gap · σ-distance ·                                                   | mean − target |     |
+| Performance mode  | Cpk · % out-of-spec (already shipped — `cpk-pareto` chart slot in `analysisStrategy.ts`) |
+| Yamazumi mode     | cycle time · waste time                                                                  |
+| Process-flow mode | step duration · throughput                                                               |
+
+Same chart card primitive across modes; content adapts. User's Pareto-driven scoping habit transfers across modes.
+
+Y-axis defaults to the characteristic-type-appropriate quality metric:
+
+- Nominal-is-best: `|mean − target|` or `Cpk gap`
+- Smaller-is-better: `% over USL` or upper-tail mean
+- Larger-is-better: `% under LSL` or lower-tail mean
+
+### 9.5 Methodological alignment (multi-axis Pareto)
+
+A Cpk improvement project anchored on count would target Surface defects first (most common). A project anchored on cost would target Cracks first (most expensive). Both are right answers to _different_ questions. Locking the analyst into one axis silently forces a methodology choice. World-class systems make the axis explicit and switchable.
+
+ADR-073 stays satisfied because Pareto-by-X creates per-X cells; bars are visible side-by-side rather than aggregated.
+
+### 9.6 Edge cases
+
+- **No defect data, no group-by dimension** — Pareto card simply doesn't appear. Outcome pin shows histogram + Cpk + drift + spec band.
+- **Single-product / single-shift line** — same as above. No useful slicing.
+- **Defects but no step-of-origin column** — system Pareto only; per-step Paretos absent.
+
+## 10. Three composable canvas filter states
+
+The canvas has three independent filter states that compose declaratively:
+
+| State               | Source                             | Persistence                          |
+| ------------------- | ---------------------------------- | ------------------------------------ |
+| **Time window**     | `TimelineWindow` filter            | Per-investigation                    |
+| **Scope filter**    | Pareto bar selection (or chip add) | Per-investigation                    |
+| **Pareto group-by** | Pareto picker setting              | Per chart card; investigation-scoped |
+
+Visual: three filter chip rows at the top of the canvas (purple / blue / amber respectively) with `×` to clear.
+
+All three compose without new aggregation primitives. The canvas renders against the filtered + grouped data; Cpk + drift + Pareto bars all read the same filtered set. ADR-073 holds: per-(node × context-tuple × scope) buckets stay heterogeneity-aware.
+
+Examples of legitimate compound state:
+
+- "Last 30 days, scoped to top-3 products, Pareto by lot_id"
+- "Tuesday's shift, all products, Pareto by defect_type weighted by cost"
+- "Investigation window (rolling), scoped to ProductC, Pareto by operator weighted by % out-of-spec"
+
+## 11. Graceful degradation
+
+Three failure modes the design handles explicitly:
+
+| Failure mode                                    | UX response                                                                                                                 |
+| ----------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------- |
+| **No outcome candidate has goal-keyword match** | Banner + rename affordance + free-text "I expected outcome to be" note + skip path. System learns from user's pick (§5.3.3) |
+| **Vague goal narrative**                        | Outcome detection falls back to keyword + cardinality heuristics; same banner if no candidate scores well                   |
+| **No useful scope dimensions**                  | Pareto card omitted; `+ add scope dimension` hint near outcome (or surfaced via CoScout coaching in Azure tier)             |
+| **Cryptic column names**                        | Outcome detection low-confidence; user picks manually + can rename inline                                                   |
+| **Different-shape paste**                       | Source axis classifier suggests "create new Hub instead"                                                                    |
+| **Overlap or different-grain paste**            | Block — explicit user choice required                                                                                       |
+
+Pattern: VariScout never silently _guesses_ on methodology-load-bearing questions. It surfaces uncertainty and asks; it does not hide it.
+
+## 12. Engine reuse
+
+Almost no new infrastructure is required. The framing layer connects shipped pieces:
+
+| Existing piece                                                    | Used for                                                 |
+| ----------------------------------------------------------------- | -------------------------------------------------------- |
+| `detectColumns()` + `inferMode()`                                 | Stage 3 outcome detection + lens suggestion              |
+| `validateData()` + `DataQualityReport` (ADR-069 B1)               | Stage 3 inline missing-pct + NaN/Inf flags               |
+| `suggestNodeMappings` (Azure migration engine)                    | A.2-paste match summary card                             |
+| `SpecEditor` + `InlineSpecEditor`                                 | Stage 3 spec inputs                                      |
+| `TimelineWindow` primitive (Multi-level SCOUT V1)                 | Match-summary timeline preview                           |
+| `statusForCpk` + characteristic-type detection                    | Capability badges + spec-default heuristics              |
+| `ParetoChart` + `StepErrorPareto` (production-line-glance C2)     | Canvas-attached Pareto                                   |
+| `useFilterHandlers` / `applyFilter` (PWA dashboard)               | Cross-chart filter propagation extended to canvas        |
+| `Question` / `SuspectedCause` / `CausalLink` / `Finding` entities | Investigation-grammar primitives                         |
+| ADR-038 staged analysis                                           | Watson rational-subgroup gate when temporal gap detected |
+
+New surfaces (this spec introduces):
+
+- The framing card / Stages 1, 3, 5 forms in the entry-to-canvas path
+- The match-summary card with two-axis classifier
+- The join-key suggestion sub-card for multi-source detection
+- Per-row provenance fields (`source`, `origin`, `imported_at`, `snapshot_id`, `join_key`, `row_timestamp`)
+- `primaryScopeDimensions` Hub config field
+- Pareto two-picker header (group-by + weighted-by)
+- "Make this the investigation scope" affordance from Pareto selection
+
+## 13. Out of scope
+
+These are deferred to sibling specs:
+
+- **Spec 2 — Manual canvas authoring:** drag-to-connect, multi-select sub-step grouping, branch / join arrow drawing, naming defaults, hit-test rules, two-level nesting enforcement
+- **Spec 3 — Cards / drill-down / mode lenses:** detailed step card design, drill-down floating overlay UX, mode-lens reskin mechanism, Pareto axis switcher implementation
+- **Spec 4 — Canvas overlays:** investigations / hypotheses / suspected causes / findings overlay rail, Wall projection sync (Q4 dual-home)
+- **Spec 5 — IndexedDB persistence schema:** PWA Hub-of-one storage shape, migration handling, multi-tab sync
+
+This spec ends at _"canvas first paint"_ (Mode B) or _"canvas with restored state"_ (Mode A).
+

+
+## 15. Delivery phasing (V1 vs V2)
+
+Per `feedback_full_vision_spec`, the design above is the complete vision. Phasing here describes _delivery sequencing_, not design partitioning.
+
+### V1 (this spec's first delivery)
+
+- Two-layer model + investigation grammar
+- Mode B Stages 1–3 + Stage 5
+- Mode A.1 + A.2-paste (PWA + Azure)
+- Mode A.2-evidence-source background ingestion (Azure)
+- **PWA persistence (Q8-revised — Option 4 hybrid):** session-only by default; opt-in "Save to this browser" surfaces an IndexedDB-backed Hub-of-one (`apps/pwa` Dexie schema with single Hub row); `.vrs` file export/import always available as escape hatch. Constitution P1 + P8 preserved. `apps/pwa/CLAUDE.md` hard rule updated.
+- Match-summary card: 2-axis classifier with all 4 source cases + 6 temporal cases
+- Block on overlap and different-grain
+- Multi-source via shared keys: detection + name+overlap join-key suggestion + per-source provenance + per-source independent timelines
+- Defect anchoring (multi-anchor) + Pareto on canvas (per-step mini + system) + two pickers + Y axis adapts to mode
+- Three composable filter states
+- Graceful degradation paths
+- Primary scope dimensions sub-step at Stage 3
+- Hub config: `primaryScopeDimensions`, `processGoal`, `outcomes[]`, `specs{}`
+- Schema for per-row provenance fields
+
+### V2 (later delivery cycles)
+
+- **Auto-detect join keys via value overlap** (no name heuristic; works on cryptic IDs)
+- **Hierarchical temporal alignment** — lot windows derived from telemetry, defect events placed within lot windows; canvas shows time at the lot grain
+- **Late-arriving data reconciliation + auto-deduplication** (overlap handling without forcing user choice for every paste)
+- **Time-travel queries** — Cpk AS OF date; capability over investigation period
+- **Composite group-by** — heatmap Pareto (`defect_type × product_id`)
+- **Pareto trend over time** — Pareto shifts week-by-week
+- **Severity-weighted Y axis** — Watson G11 methodology addendum (separate severity-rank table per defect type)
+- **Linked Hubs** (Option C from multi-source design) — cross-Hub views for org-level analysis
+- **Multi-step source-shaping transforms** — pivot / unpivot / aggregate / filter pre-join
+- **Industry templates** — "Pick a starting template: Injection molding / Assembly / Baking" for Stage 1
+- **"Paste spec table"** — bulk import of customer specs
+- **Stage auto-suggestion** — when temporal gap suggests process-state change, suggest staging analysis (per ADR-038)
+
+## 16. Verification (acceptance criteria)
+
+V1 delivery is complete when:
+
+### End-to-end Mode B (PWA + Azure)
+
+- [ ] First-time user pastes a CSV; framing card appears with goal narrative scaffold chips
+- [ ] Detection runs with goal context; outcome candidates ranked with sparkline + missing-% + match confidence
+- [ ] User multi-selects 2 outcomes; inline spec forms appear under each (no σ defaults)
+- [ ] Skip-spec path produces canvas with `mean ± σ + n` fallback chip on outcome pin
+- [ ] Primary scope dimensions sub-step suggests + accepts user override
+- [ ] Stage 5 modal opens with skip path → canvas-only (observation-triggered EDA)
+- [ ] Canvas first paint shows goal banner + outcome pin + auto-classified factor / metadata chips
+- [ ] Hub name auto-extracts from goal first sentence; editable
+
+### End-to-end Mode A (PWA + Azure)
+
+- [ ] A.1: reopen Hub → canvas with restored state, no framing card, "+ New investigation" button visible
+- [ ] A.2-paste: paste new CSV → match-summary card with timeline preview + 2-axis classification + per-case actions
+- [ ] Block cases (overlap, different grain) prevent silent merge; user must choose
+- [ ] Action choices preserve provenance (replaced-rows archived with `replaced-by` tag)
+- [ ] Multi-source: paste of QC defect data joins via `lot_id` with cardinality preview
+- [ ] Per-source independent timelines render correctly
+- [ ] A.2-evidence-source (Azure only): background ingestion shows "X new snapshots ↑" indicator on canvas reopen
+
+### Defect data + Pareto
+
+- [ ] Defect-mode data anchors to step (when `step_rejected_at` column present) or outcome (when absent)
+- [ ] Per-step mini-Pareto chips render on step cards with rejection data
+- [ ] System Pareto card on outcome pin with two pickers (group-by + weighted-by)
+- [ ] Pareto bar click → canvas-wide scope filter; multi-select supported
+- [ ] "Make this the investigation scope" promotes selection to Stage 5 with issue auto-filled
+- [ ] Y axis adapts to active mode lens (count / cost / time / Cpk gap / etc.)
+- [ ] Edge case: no group-by dimension → Pareto card omitted, canvas stays clean
+
+### Graceful degradation
+
+- [ ] Cryptic column names + vague goal: low-confidence banner + rename + skip-outcome path
+- [ ] Hub records user's pick → future paste of similar shape ranks higher
+
+### Engine reuse
+
+- [ ] No new chart primitives introduced; canvas Pareto reuses shipped `ParetoChart` + `StepErrorPareto`
+- [ ] Match-summary timeline reuses `TimelineWindow`
+- [ ] Outcome detection reuses `detectColumns()` + `inferMode()` + `DataQualityReport`
+- [ ] `suggestNodeMappings` powers A.2-paste column match
+- [ ] No new persistence primitives in V1 (Spec 5 details schema)
+
+### Methodology guards (CI-checkable)
+
+- [ ] No σ-based suggestions for LSL/USL anywhere in code (CI guard test)
+- [ ] No silent merge on overlap or different-grain paste (block-case guard test)
+- [ ] Per-row provenance fields present on all imported rows (schema test)
+- [ ] ADR-073 structural absence preserved — no aggregation primitive across heterogeneous sources / specs / contexts
+
+---
+
+**Predecessor brainstorm:** the §8 vision walkthrough at `~/.claude/plans/lets-do-this-next-rustling-simon.md` locked Q0 + Q1–Q11; this spec inherits those anchors (§14).
+
+**Implementation plans:** V1 is delivered in 4 slices.
+
+- **Slice 1 (in flight):** [`docs/superpowers/plans/2026-05-03-framing-layer-v1-slice-1.md`](../plans/2026-05-03-framing-layer-v1-slice-1.md) — Mode B Stages 1–3 + canvas first paint + Mode A.1 reopen + PWA opt-in IndexedDB persistence + `.vrs` export/import (Q8-revised hybrid).
+- **Slice 2 (planned):** Mode A.2-paste match-summary card + Mode A.2-evidence-source background ingestion + per-row provenance fields + Stage 5 modal full implementation.
+- **Slice 3 (planned):** Multi-source via shared keys (join detection + per-source provenance + per-source independent timelines).
+- **Slice 4 (planned):** Defect anchoring (multi-anchor) + Pareto on canvas (per-step mini + system) + two pickers + Y-axis adapts to mode + canvas-wide scope filter + three composable filter states UI.
+
+**Visual companion mockups** archived at `.superpowers/brainstorm/6149-1777834116/content/` (gitignored; preserved locally for reference). Mockups: `framing-layer-flow-v4.html` (Stage 3 inline specs); `mode-a-temporal-alignment.html` (match-summary card with timeline preview); `multi-source-join.html` (join-key suggestion); `pareto-on-canvas.html` (defect-mode Pareto integration); `pareto-multi-product.html` (two pickers + scope selection); `pareto-no-defects.html` (capability-mode Pareto Y-axis adaptation).
+
+**Next:** brainstorming Spec 2 (manual canvas authoring) — drag-to-connect, multi-select sub-step grouping, branch/join. The Frame layer's anchored decisions (process goal banner; outcome pin; primary scope dimensions; canvas first paint expectations) carry into Spec 2.

+# VariScout — Product Vision
+
+> **Canonical product vision.** This document supersedes the 2026-04-27 operating-model + product-method-roadmap specs. It is the single source describing what VariScout is, what it does, and what's in/out of scope. Implementation plans should cite which section of this vision they advance.
+
+## 1. Thesis
+
+VariScout operationalizes **structured process learning for industrial operations**. Real production data goes in. A persistent **logic map** of the process that produced it comes out. Capability monitoring, investigation, and response paths all run against that same map. **The map is the product.** Everything else — modes, charts, investigations, findings, response paths — is a view onto the map or a derivation from it.
+
+The map is owned by a **Process Hub** (one Hub per process line). Every dataset belongs to a Hub. Every Hub IS its map. Hubs persist across investigations, snapshots, and time. The user authors a Hub's map once (or refines it incrementally); analysis runs on it many times.
+
+---
+
+## 2. Methodology spine
+
+VariScout's substance is methodological, not analytical fashion. The product expresses these commitments in software so that following them is the path of least resistance.
+
+### 2.1 Three-level model
+
+Every process is read at three levels simultaneously:
+
+- **Level 1 — System / Outcome.** What the customer experiences. Captured as the Y measure(s) on the right end of the canvas. Per-Hub there is at least one outcome.
+- **Level 2 — Process Flow.** The sequence and topology of steps that produce the outcome. Captured as the spine of the canvas: nodes (steps and sub-steps), step→step arrows (flow with branch and join).
+- **Level 3 — Local Mechanism.** The inputs, settings, materials, environment, and per-step measurements that drive each step. Captured as columns of incoming data linked to specific step nodes via directed arrows.
+
+Each level has different users (process owner / analyst / operator), different artifacts (outcome card / flow graph / column-to-step links), and different rhythms (rare / per-investigation / continuous), but they share one map.
+
+### 2.2 Observed vs expected — the universal lens
+
+Every analysis answers: _is what we see different from what we expected?_ This shared structure (observed value compared to a model of expected value) underlies chi-square, regression, ANOVA, and capability indices. The vision commits to making this lens explicit in coaching: when a chart surfaces an anomaly, the explanation says _"observed X vs expected Y; difference is significant by Z"_ — not just "anomaly detected."
+
+### 2.3 Methodology rules (enforced in the engine, taught in the UI)
+
+- **No statistical roll-up across heterogeneous units (ADR-073).** Capability, defect rates, and trend metrics are computed per (node × context-tuple). The canvas's branch/join + context-propagation model (§3.3) makes this structural — heterogeneous siblings cannot be silently averaged.
+- **Contribution, not causation.** EDA reveals factors that contribute to variation; it does not prove causality. The product's language stays in contribution terms ("explains 23% of variation"), never in causal claims ("X causes Y"). CoScout coaching enforces this.
+- **Sample-size honesty.** Cpk is suppressed for n < 10 (deterministic refusal, not a hint). Cpk is badged "trust pending" for n < 30. Trust is a first-class card overlay, not a footnote.
+- **Target-relative Cpk grading.** Cpk grades band against the user-set target (default 1.33), never against literature constants (1.67/1.33/1.00). `statusForCpk` is the one source of truth.
+- **Geometric interaction language.** Two-factor interactions are described in geometric terms (ordinal / disordinal / parallel) and their effect on Y. The product never assigns "moderator" or "primary" roles to one factor over another — that's a causal claim VariScout doesn't make.
+
+### 2.4 The five response paths
+
+For any current state of any step, exactly five response paths exist. The drill-down panel (§5) presents these as the explicit set:
+
+1. **Quick action** — a fix small enough to do today, no investigation needed (e.g., re-tune a parameter back to spec).
+2. **Focused investigation** — a thread of EDA on this card. Opens the Investigation graph (questions → hypotheses → evidence → findings) scoped to this step.
+3. **Charter** — formal improvement project (DMAIC or similar). Promotes the situation to a tracked initiative with milestones.
+4. **Sustainment** — capability is fine; schedule the cadence to verify it stays so. Sets a snapshot frequency on this step.
+5. **Handoff** — document and pass to another team / shift / function. Produces a handoff package with current state + recommended next steps.
+
+These paths are H1's thesis made concrete. Every card and every drill-down surfaces them.
+
+---
+
+## 3. The artifact — Process Hub = Canvas = Logic Map
+
+### 3.1 The map IS the Hub
+
+A Process Hub holds the persistent logic map of a process line. There is no separate "Hub model" and "FRAME map model" — they are the same artifact. Every operation that today asks "where does this go?" (Hub or investigation? Map or specs?) collapses into operations on the Hub's canvas.
+
+A Hub holds:
+
+- **Map structure** — DAG of steps (see §3.3).
+- **Specs per column / per step** — target, USL, LSL, cpkTarget, characteristic type. Per the existing per-characteristic spec model.
+- **Named contexts** — context dimensions discovered through branch/join (§3.3).
+- **Cadence definition** — manual / hourly / shiftly / daily / weekly. Drives Evidence Source semantics.
+- **Snapshot history** — every dataset matched to this Hub becomes a snapshot in its history.
+- **Finding history** — findings that have crossed the evidence threshold are anchored to map nodes.
+- **Investigation history** — every investigation run on this Hub is preserved.
+
+### 3.2 Net-new datasets match a Hub
+
+When a user uploads / pastes a new dataset, the system attempts to match its column structure to an existing Hub's map. Match → the Hub's map auto-populates the canvas → user confirms. No match → create a new Hub (optionally from a template).
+
+Today's hub-migration `suggestNodeMappings` engine (Azure) is the matcher. The vision moves it from the migration wizard into the upload entry path itself.
+
+### 3.3 Canvas structure (the 10 commitments)
+
+The canvas is a directed acyclic graph with the following primitives.
+
+| #   | Commitment                      | Detail                                                                                                                                                                                                                                   |
+| --- | ------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| 1   | One continuous canvas           | Replaces today's FRAME (`ProcessMapBase` river-SIPOC, `LayeredProcessView`, `LayeredProcessViewWithCapability`) with a single growing surface. No b0 → b1/b2 transition shock.                                                           |
+| 2   | Logic map semantic              | Every column maps to a step (or is marked unassigned). The map answers _which column came from which step?_ Hypotheses are an optional overlay (§3.4).                                                                                   |
+| 3   | Hub IS the map                  | One persistent map per process line. Investigations on the same Hub share the SAME map. Never redrawn per investigation.                                                                                                                 |
+| 4   | Directed arrows for column↔step | Direction encodes meaning: column → step = input/control to the step. Step → column = measured AT the step (an output / intermediate Y).                                                                                                 |
+| 5   | Two-level nesting               | A step can contain sub-steps. One level of nesting only. Sub-steps tagged **parallel** (default; like chambers) or **sequential** (like a sub-sequence inside a parent).                                                                 |
+| 6   | Full DAG with branch + join     | Steps can branch (one→many) and join (many→one). Real processes do both.                                                                                                                                                                 |
+| 7   | Context propagation             | When parallel sub-steps converge to a downstream step, that step's analysis is automatically grouped BY upstream origin. ADR-073 enforced structurally — context follows the path.                                                       |
+| 8   | Arrow scope = arrow target      | Drag an arrow to the parent step → applies to all children. Drag to a specific child → child-only. Drag to a multi-selection → subset. No new construct; falls out of the graph model.                                                   |
+| 9   | Plain-language terminology      | "Tributary" and "CTS" are retired as user-facing terms. The canvas uses _step_, _sub-step_, _column_, _input_, _output_, _outcome_. The methodological distinction CTS-vs-CTQ survives as concept; the acronyms don't survive as labels. |
+| 10  | Process steps are optional      | A minimal canvas is just Y + X columns (no steps). Steps are added when X's belong to specific stages — _useful when relevant, never required_. The canvas grows from declaration to fully structured map.                               |
+
+### 3.4 Hypotheses as optional overlay
+
+In addition to the data-provenance arrows (§3.3 #4), users may **optionally draw a hypothesis arrow** from one column (or one step) to another, declaring "I suspect this affects that." Hypothesis arrows live as one of several canvas overlay toggles — alongside investigations, suspected causes, and recent findings (see §5.4). Default-hidden; the user toggles to reveal.
+
+**Promoted vs draft visual distinction.** When an analysis run produces evidence sufficient to cross the threshold (ADR-064 SuspectedCause hub semantics), the hypothesis is promoted: it renders as a **node marker** on the affected step rather than as an arrow. Draft / unpromoted hypotheses render as **faint arrows between steps** when the overlay is on. Both states reflect the same underlying entity in the investigation graph — only the canvas projection changes. This prevents canvas clutter on mature Hubs (30+ hypotheses become unreadable as always-on arrows) while keeping the at-a-glance "which steps have suspected causes" read intact.
+
+This unifies the canvas with the SuspectedCause hub construct (ADR-064): a promoted hypothesis is just a hypothesis that has crossed the evidence threshold and gets the node-marker treatment. The investigation graph (questions, findings, evidence) survives as the underlying data model; the canvas is one of two spatial expressions of it (the Investigation Wall is the other — see §5.6 for dual-home semantics).
+
+---
+
+## 4. The user journey
+
+The journey loop. Each step references which canvas commitment or methodology rule it expresses.
+
+1. **Upload** — paste / file / sample / Evidence Source (recurring data contract). All paths converge to the same column-detection + parsing step. Today's PWA `PasteScreen` + Azure `EditorEmptyState` already do this; the vision doesn't change ingestion mechanics, only what happens next.
+2. **Match-or-create-Hub** — the system attempts to match incoming columns to an existing Hub's map. Match found → Hub's map applies → user confirms. No match → create new Hub (optionally from template).
+3. **Refine the canvas** — confirm column-to-step assignments. Auto-suggestions from column names (`Chamber_3_*` → step "Chamber 3"). Add or refine structure if helpful (process steps, sub-steps, branches). Mark unassigned columns explicitly. Set specs (target / USL / LSL / cpkTarget) per column or per step.
+4. **See the data** — canvas re-renders with **cards-per-step**. Each card shows inline mini-chart (histogram for measurements, distribution for categoricals) and capability badge (Cpk vs target, sample-size trust, drift indicator).
+5. **Click a card** — drill-down opens. Shows: that step's analysis, recent values, related context tuples (per §3.3 #7), linked investigations, and the **five response-path CTAs**.
+6. **Choose a response path** — quick action / focused investigation / charter / sustainment / handoff. Each has its own continuation; focused investigation opens the Investigation graph (questions → hypotheses → evidence → findings) pre-loaded with the clicked step's context and any hypothesis arrows from §3.4.
+7. **Findings link back to cards** — when an investigation produces a finding, the finding becomes visible on the relevant card (badge + link). Cross-investigation patterns surface in the Wall (§5.6).
+8. **Sustain** — cadence triggers the next snapshot; the Hub's history grows; capability and findings update; loop returns to step 4 with fresher data.
+
+The journey has one entry, one continuous canvas through the middle, five exits (response paths), and a loop back to the top. Today's tab-switching between Frame / Analysis / Investigation / Hub flattens into this single loop.
+
+---
+
+## 5. Surfaces (concrete UI commitments)
+
+### 5.1 The Canvas
+
+Central spatial home for everything. Replaces today's FRAME workspace (`ProcessMapBase`, `LayeredProcessView`, `LayeredProcessViewWithCapability`). Shipped in both PWA and Azure. Same component, same data model, same gestures.
+
+### 5.2 Cards
+
+Per-step rendering. Each card shows:
+
+- **Step name** + (if nested) parent context.
+- **Inline mini-chart** — histogram for measurements, distribution for categoricals, mini-time-series for high-cardinality.
+- **Capability badge OR fallback** — when specs are set: Cpk vs target, color per `statusForCpk`, suppressed for n < 10, badged "trust pending" for n < 30. **When specs are absent: the card swaps the Cpk badge for `mean ± σ + n` and shows a `+ Add specs` chip.** When specs are partial (e.g., LSL only): show the side that's set + a "complete specs" chip. The chip / icon is the spec-edit affordance for the unset state.
+- **Drift indicator** — recent vs prior, when snapshot history exists.
+- **Spec edit affordance** — small `[✎]` icon on the card (hover-reveal on desktop, always-visible on mobile) → opens inline `SpecEditor` (existing component). When specs are absent, the `+ Add specs` chip described above replaces the icon as the primary affordance.
+- **Click target** — opens drill-down (§5.3). Card click is reserved for drill-down; spec edit is always the icon / chip, never the card body.
+
+### 5.3 Drill-down
+
+**Modern floating overlay anchored near the clicked card with a blurred-canvas backdrop.** Dismisses on click-out / Esc / X. On desktop the overlay floats anchored to the clicked step (positioned to keep the original card visible if possible). On mobile the same content slides up from the bottom (extends today's `EvidenceMapNodeSheet` / `MobileCategorySheet` pattern). CoScout (right rail in Azure) is untouched throughout — no panel-vs-rail contention.
+
+Contains:
+
+- The clicked step's analysis (charts scoped to step + active context tuple).
+- Linked investigations (existing investigation graph entities).
+- **Five response-path CTAs (per §2.4) — mode-aware.** Cadence-mode (mature Hub) shows all five active. First-time / no-Hub mode (PWA free tier) shows Quick action + Focused investigation active; Sustainment / Charter / Handoff dimmed with a tier-upgrade hint (no Hub anchor for cadence / charter / handoff in single-Hub PWA tier).
+- Any hypothesis arrows or promoted SuspectedCause markers incident to this step (per §3.4).
+- **Heavy on-ramps preserved:** Focused Investigation navigates to the Investigation tab (3-column workspace, shipped); Charter promotes via `usePopoutChannel` to a separate window for long authoring sessions; Sustainment confirms inline within the overlay; Handoff opens the export modal.
+
+The drill-down is a **bridge**, not a workspace. Long-form work (Investigation, Improvement, Charter) lives in dedicated surfaces; the overlay is the launchpad.
+
+Rationale for the floating-overlay shape over a right side-panel: the right rail is claimed by CoScout in Azure (per `docs/decision-log.md` §1 "Plan C3 (FRAME right-hand capability drawer) — superseded 2026-04-29 by FRAME thin-spot batch"). A floating overlay anchored to the click avoids both the C3 collision and the canvas-reflow that an in-place card expansion would cause; it also unifies desktop and mobile gestures.
+
+### 5.4 Mode lenses + canvas overlays (replaces Analysis tab)
+
+Today's analysis modes (yamazumi / performance / defect / process-flow / capability) become **lenses** applied to the canvas. Picking a lens re-skins cards to highlight that mode's metrics. There is no separate Analysis tab. The default canvas already shows baseline overlays (capability-or-mean±σ, drift, trust per §5.2); a lens is an opt-in re-skin.
+
+**Modes vs levels are orthogonal axes.** Levels (System / Process Flow / Local Mechanism, §2.1) are _which slice of the process_ you're scanning — expressed as a canvas pan/zoom, not a separate picker. Modes are _which analytical lens_ you apply to whatever you're scanning. The two cross-cut: a user can read at any level in any mode. ADR-068 (CoScout cognitive redesign) gets a corresponding amendment — coaching is mode-aware AND level-aware (level inferred from the canvas zoom state).
+
+**Canvas overlays.** Independent of mode lenses, the canvas exposes a small set of toggleable overlays, each projecting investigation graph data onto map nodes:
+
+- **Investigations** — count + status badge per step (open / supported / refuted).
+- **Hypotheses** — faint arrows for draft hypotheses (per §3.4).
+- **Suspected causes** — node markers for promoted hypotheses (per §3.4).
+- **Recent findings** — pin-style markers anchored to map nodes.
+
+With overlays off, the canvas is a clean live map. With overlays on, the canvas IS the Wall view (see §5.6 — dual-home).
+
+**Mode B reuse (PWA first-time GB).** Today's silent mode auto-inference (`packages/core/src/parser/detection.ts` + `parser/stack.ts` + the wide / yamazumi / defect detection modals) survives as a **suggested lens prompt**, not a forced mode switch. The first paint always renders something deterministic; the lens suggestion appears as a non-blocking nudge.
+
+### 5.5 Hub list
+
+Cross-Hub navigation. Today's Dashboard hub list survives, lightly reskinned to reflect Hub-as-map semantics (each Hub preview shows its map + last snapshot summary).
+
+### 5.6 Investigation Wall — dual-home
+
+The Wall is **dual-home**: it remains the canonical destination in the Investigation tab (`WallCanvas` shipped — `packages/charts/src/InvestigationWall/`) AND becomes one of the canvas overlays (§5.4). Same data, two views: the destination supports deep cross-investigation work (full-screen, command palette, hypothesis-card reordering); the canvas overlay supports cadence-loop scanning (investigation density and status badges projected onto the map nodes you're already looking at).
+
+The "destination vs overlay" framing replaces the earlier binary (separate surface vs absorbed-into-canvas) — the spec's "vs" was a false choice. Cross-investigation pattern recognition has different cognitive needs than current-investigation drill-down, so the destination stays; the overlay adds a glance read without forcing a context switch.
+
+**Methodology integration follow-up.** The methodological picture for the Wall + SuspectedCause hubs (when does an investigator pick Wall vs Evidence Map vs Question framework? Persona-specific patterns? Missing-evidence critique as principle? AND/OR/NOT composition as teachable pattern?) is a separate doc tracked in `docs/decision-log.md` §2 "Investigation Wall methodology integration brainstorm" — belongs in `docs/01-vision/eda-mental-model.md` (or successor) once decided.
+
+### 5.7 CoScout
+
+CoScout has two roles in the new world (the third — "drafts the canvas" — is intentionally cut from V1; see below):
+
+- **Coaches per step** — methodology nudges keyed to the clicked step's context (mode-aware AND level-aware coaching from existing `coScout/phases/` and `coScout/modes/` prompt modules; see §5.4 for the orthogonal mode/level axes).
+- **Stays optional** — every surface works without CoScout. Free PWA tier ships without CoScout (Constitution P8). Azure tier ships with it.
+
+CoScout does NOT make analytical claims. Its outputs are always tagged as proposals; the deterministic engine remains authoritative.
+
+**No CoScout map drafting in V1.** Canvas authoring is 100% manual click / drag / connect: existing `detectColumns()` and `inferMode()` seed suggested column roles, and the user assembles steps + arrows + sub-step groupings + branch / join via direct manipulation. AI map drafting carries ongoing prompt / eval / variance cost, while manual canvas authoring is finite design work; most factory-floor CSVs have well-named columns where manual click / drag beats AI-draft-then-review. The V1 spec commits to manual canvas authoring as a **first-class design concern** (drag-to-connect, multi-select sub-step grouping, branch / join discoverability) — clumsy manual UI would force AI back in. Revisit AI drafting in V2 only if user research shows manual stalls.
+
+---
+
+## 6. What's superseded
+
+This vision spec replaces or absorbs the following. Each item lists the disposition. **No back-compat / no migration window** — VariScout has no production users yet to preserve, and per the no-back-compat principle, deletes happen in the same PR as the replacement (see Q7 in the §8 resolution log).
+
+- **`docs/archive/specs/2026-04-27-process-learning-operating-model-design.md`** (archived at supersession) — content absorbed into §2 (methodology) and §4 (journey).
+- **`docs/archive/specs/2026-04-27-product-method-roadmap-design.md`** (archived at supersession) — horizons live there as a "delivery-sequence reference" (re-tagged); they are NOT part of this vision spec. Vision describes destination; horizons describe path.
+- **`docs/01-vision/methodology.md`** — substantially absorbed into §2; remains as a longer narrative companion with a forward pointer. Methodology terms cross-reference `docs/glossary.md`, which is the canonical home for retired-terms (tributary, CTS) and their replacements.
+- **Today's `Frame` and `Analysis` top-level tabs** — both retire. The Canvas (§5.1) replaces both. Cognitive grouping rationale: Frame and Analysis are the same job ("look at the live map and its current state"); Investigation, Improvement, and Report each have a distinct cognitive shape and keep their own surfaces. Top-level nav post-cutover: `[ Hubs ] [ Canvas ] [ Investigation ] [ Improvement ] [ Report ]`. `JourneyPhase = 'frame' | 'scout' | 'investigate' | 'improve'` stays internal in `packages/core/src/types` (used for CoScout tool gating + investigation-internal phase detection) but stops driving top-level nav.
+- **`packages/ui/src/components/LayeredProcessView/LayeredProcessView.tsx`** + `LayeredProcessViewWithCapability.tsx` — shipped via production-line-glance C2 (Apr 29). Absorbed into the Canvas as a mode lens. Deleted in the same PR that ships the Canvas.
+- **`packages/ui/src/components/ProcessMap/ProcessMapBase.tsx`** (river-SIPOC, ADR-070) — absorbed into the Canvas. ADR-070 amended: "superseded by vision spec; river metaphor retired; FRAME workspace retired as a top-level route." Deleted in the same PR.
+- **`apps/azure/src/components/editor/FrameView.tsx`** + `apps/pwa` `FrameView` / `FrameViewB0` — Frame route retires; b0 lightweight render becomes the sparse-Canvas first paint when no map is authored yet. Deleted in the same PR.
+- **"Tributary" terminology everywhere** — UI strings (`+ add tributary…`, "Group by tributary"), i18n keys (`wall.tributary.ariaLabel`), code comments. Replaced with "factor", "input arrow", or simply removed. Glossary at `docs/glossary.md` carries the retired-terms list.
+- **"CTS" as a user-facing acronym** — replaced with plain language ("outcome at the customer" or similar). The CTS-vs-CTQ methodological distinction survives as concept; the acronyms don't survive as labels.
+- **SuspectedCause hubs as separate construct (ADR-064)** — become "promoted hypotheses on the canvas" (per §3.4 — node markers). The data model entity survives unchanged; the user-facing concept folds into the canvas.
+- **The 5-lens `ProcessStateLens` render-time projection** — reconciled with the new card overlay model. Lens semantics preserved (`outcome | flow | conversion | measurement | sustainment`); rendering shape changes from "stacked bands" to "card overlays + mode-lens reskin."
+
+---
+
+## 7. What stays
+
+- **Production-line-glance C2 engine** — per-(node × context-tuple) capability computation (PR #107). The Canvas exposes this engine; the math doesn't change.
+- **ADR-073, ADR-074, and all methodology rules.**
+- **Investigation graph data model** — questions, hypotheses, findings, SuspectedCauses as entities. Surface changes; data model survives.
+- **Hub data model** — already supports most of what's described here (map structure, specs, cadence, snapshots, findings).
+- **Per-characteristic spec model** — shipped (target, USL, LSL, cpkTarget, characteristicType per column).
+- **PWA + Azure dual deployment** (ADR-059 web-first stays).
+- **CoScout system architecture** — existing prompts, tool registry, knowledge model; role refinement is the change, not architecture.
+- **Evidence Source concept** — recurring data contracts. Folded into "Hub with cadence" semantics; not a separate construct.
+- **Customer-owned-data principle (ADR-059)** — browser-only processing; data stays in customer's tenant.
+- **Pop-out window pattern** — `usePopoutChannel` + BroadcastChannel (`packages/hooks/src/usePopoutChannel.ts`). Three live consumers today (Evidence Map, Findings Board, Improvement Window) — extended in V1 as the on-ramp for heavy drill-down work (Charter authoring) per §5.3.
+- **PWA SW behavior** — autoUpdate + skipWaiting (ADR-075 Amendment). Canvas chunk wraps in `lazyWithRetry` to handle the chunk-404 failure mode when SW auto-updates between sessions. No prompt-mode SW.
+
+### Tier split (PWA vs Azure)
+
+The Canvas-as-home commitment requires persistence — a home that vanishes is a teaser, not a tool.
+
+- **PWA = session-only by default with opt-in local persistence.** Users can explicitly opt in via a "Save to this browser" action (IndexedDB-backed Hub-of-one — single Hub, browser-tenant-only per ADR-059, Constitution P1 customer-owned data) AND/OR export their work as a `.vrs` file (file-based persistence; user owns the file). Both paths are always available; the user picks. Same Canvas UX as Azure once data is loaded. Multi-Hub portfolio + cloud sync + cadence-driven Evidence Sources + CoScout + team features remain Azure-tier exclusive. **Companies' factory data still flows to their own Azure tenant per ADR-059** — PWA persistence is for individual / training use (LSSGB students; demos; casual analysts), not company governance. Constitution P8 (no AI in free tier) preserved.
+- **Azure tier adds** cloud sync, multi-Hub portfolio, cadence-driven Evidence Sources, CoScout (Constitution P8 — AI is Azure-only), and team features (sharing, comments, real-time collab).
+

+
+## 8. Resolved decisions (2026-05-03)
+
+The 11 brainstorm-default markers that originally lived here have been resolved. A new **Q0** ("tab vs canvas scaffold") emerged during journey mapping and was answered first because §8's other questions silently assumed an answer to it. The decisions are summarized below; full rationale, rejected alternatives, and follow-up work live in `~/.claude/plans/lets-do-this-next-rustling-simon.md` (the §8 walkthrough plan) and the corresponding entry in `docs/decision-log.md` (2026-05-03 — Vision §8 open questions resolved).

+| Q0  | Tab vs canvas scaffold (new, structural)       | Canvas eats Frame + Analysis tabs. Investigation / Improvement / Report keep own surfaces. Wall is dual-home (destination + canvas overlay). `JourneyPhase` retires as a top-level nav primitive.                                                                                                                                                                                     | §6                |

+| Q2  | Spec-edit gesture (§5.2 — confirms + extends)  | Small `[✎]` icon on card → inline `SpecEditor`. Card-display fallback rule when specs are absent: swap Cpk badge for `mean ± σ + n` and add a `+ Add specs` chip.                                                                                                                                                                                                                     | §5.2              |

Levels (System / Flow / Local) are orthogonal — canvas pan/zoom, not a picker.                                                                                                                                                                                                                                             | §5.4              |
+| Q4  | Wall fate (§5.6 — refines binary)              | Wall is dual-home: canonical destination in Investigation tab AND a canvas overlay toggle. Same data, two views. Methodology integration doc tracked separately.                                                                                                                                                                                                                      | §5.6              |
+| Q5  | CoScout drafting authority (§5.7 — overrides)  | No CoScout map drafting in V1. Manual click / drag / connect canvas authoring as a first-class design concern. CoScout coaching role unchanged.                                                                                                                                                                                                                                       | §5.7              |
+| Q6  | Horizons appendix (§6 — confirms)              | Horizons live outside the vision spec (delivery-sequence reference at `docs/archive/specs/2026-04-27-product-method-roadmap-design.md`). Vision spec stays timeless.                                                                                                                                                                                                                  | §6                |
+| Q7  | Migration path (overrides)                     | Hard cutover. Delete Frame + Analysis routes; ship Canvas; no parallel-run window; no back-compat. No users yet to preserve.                                                                                                                                                                                                                                                          | §6                |
+| Q8  | PWA-vs-Azure tier split (revised 2026-05-03)   | PWA = session-only by default with opt-in local persistence (IndexedDB Hub-of-one) AND always-available `.vrs` export/import. `.vrs` doubles as a **shareable training scenario** — trainers package datasets + Hub state for students to import. Azure adds cloud sync + multi-Hub + cadence-driven Evidence Sources + CoScout + team features. See decision-log "Q8 revised" entry. | §7 ("Tier split") |
+| Q9  | PWA SW behavior (confirms)                     | `lazyWithRetry` on Canvas component. ADR-075 (autoUpdate + skipWaiting) stays. No prompt-mode SW.                                                                                                                                                                                                                                                                                     | §7                |
+| Q10 | Glossary / terminology guide (overrides home)  | `docs/glossary.md` is canonical for all methodology terms (including retired tributary / CTS). `docs/01-vision/methodology.md` cross-references the glossary.                                                                                                                                                                                                                         | §6                |
+| Q11 | Hypothesis overlay (§3.4 — confirms + refines) | Optional canvas overlay (one of several toggles). Promoted hypotheses (ADR-064 SuspectedCause hubs past evidence threshold) render as node markers; draft hypotheses render as faint arrows. Default off.                                                                                                                                                                             | §3.4              |

+## 9. Verification
+
+How we know this vision spec is realized as the canonical artifact:
+
+- **One canonical document.** This file lives at `docs/superpowers/specs/2026-05-03-variscout-vision-design.md`. The two superseded 2026-04-27 specs are moved to `docs/archive/specs/` with frontmatter pointing forward.
+- **Every in-flight plan can be measured against the vision.** For each plan in `docs/superpowers/plans/`, the plan's frontmatter references which section of the vision it advances. Plans that don't fit get killed or rewritten.
+- **New PRs cite vision sections.** PRs touching FRAME / Hub / Analysis surfaces include "Advances vision §X" in the description. Plan-status drift becomes detectable by audit.
+- **Memory entries reflect the vision.** `MEMORY.md` and topic memories update to point at this spec; entries about superseded concepts are corrected or deleted.
+- **The 10 canvas commitments (§3.3) become the FRAME canvas detail spec.** A separate spec at `docs/superpowers/specs/<date>-canvas-detail-design.md` will detail UX (drag affordances, hit-test rules, animation, mobile, exact card layouts), inheriting the §8 resolved decisions above. This vision spec doesn't try to do that work; the canvas detail spec is the next brainstorming target.

 ## Invariants
 
 - Sub-path exports are public API. Adding a new sub-path requires updating `packages/core/package.json` exports field + `tsconfig.json` paths.
-- Available sub-paths: root (barrel), /stats, /ai, /capability, /parser, /findings (incl. `findings/drift.ts`), /variation, /yamazumi, /tier, /types, /i18n, /glossary, /export, /navigation, /responsive, /performance, /time, /timeline (TimelineWindow + applyWindow), /throughput (computeOutputRate, computeBottleneck), /projectMetadata, /strategy, /ui-types, /evidenceMap, /defect.
+- Available sub-paths: root (barrel), /stats, /ai, /capability, /parser, /processHub (CharacteristicType, OutcomeSpec, ProcessHub, InvestigationStatus, etc.), /findings (incl. `findings/drift.ts`), /variation, /yamazumi, /tier, /types, /i18n, /glossary, /export, /navigation, /responsive, /performance, /time, /timeline (TimelineWindow + applyWindow), /throughput (computeOutputRate, computeBottleneck), /projectMetadata, /strategy, /ui-types, /evidenceMap, /defect.
 - `resolveMode()` + `getStrategy()` in `src/analysisStrategy.ts` is the mode dispatch point. New analysis modes must register here.
 - The stats engine is the authority for numeric claims. CoScout receives stat results; it does not recompute.
 - Numeric safety has three boundaries (ADR-069): B1 parser rejects NaN via `toNumericValue`; B2 stats functions return `undefined`; B3 display uses `formatStatistic`.
