 Candidate trace note: candidate-level `sourceItemId` / `traceId`, `sourceTitle` / `lensTitle`, and `sourceExcerpt` / `sourceQuote` are preserved in ranked items, `buildOrderDetails`, and `handoff.itemTrace`. Lens-only Build Order text is also split into deterministic `concept-map.lenses.channel#N` source IDs with the original labelled sentence carried as `sourceQuote`, so pasted paid Concept Maps remain traceable even without explicit candidate objects. String items in laned Build Order arrays now also receive deterministic section-local source IDs such as `concept-map.buildOrder.validateNext#1` and carry the original string as `sourceQuote`, so simple Scattermind exports stay addressable downstream instead of becoming anonymous `feature-1` rows. Ranker also accepts the current Scattermind storage-row shape with `referenceCode`, `ideaText`, `context`, and string-valued `fullReadingJson` / `full_reading_json`; it expands the saved paid Concept Map before ranking so operators do not have to hand-copy lenses out of Appwrite rows. It also accepts private reading/API envelopes with object-valued `reading` / `fullReading` and `glimpse`, preserving `referenceCode` and `initialPrompt` while treating `reading` as the paid Concept Map. Stringified bridge envelopes in fields such as `rankerInput`, `rankerBridge`, `rankReady`, `bridgePayload`, or `continuationPlan` are expanded the same way, so Appwrite/string-copy handoffs do not have to be manually unwrapped before ranking. If the row only has free Snapshot data (`glimpseJson` / `glimpse_json` / `snapshotJson`), Ranker expands that Snapshot into a minimal continuation order: one manual proof plus the first evidence question, with the Snapshot reference code/title preserved for provenance. The public paste form mirrors this: a prose-wrapped/fenced Appwrite row paste stays intact for the API instead of unwrapping the stringified reading into nonsense fields. The decision `brief.quickGlance.sourceTrace` now repeats the winning item's source section/id/title/quote, and both `brief.source.originalPromptExcerpt` / `handoff.source.originalPromptExcerpt` or, when the original prompt is unavailable, `sourceSummaryExcerpt` carry the source context into the bridge handoff.
 
-Soft Scattermind labels are accepted at the bridge boundary so Scattermind does not need to use harsh verdict copy in its own product surface. Lens text can say `Continue first`, `Make tangible`, `Try next`, `Evidence next`, `Validate manually`, `Manual proof`, `Hold for later`, or `Set aside`, with either colon or reader-friendly dash separators (`Continue first: …`, `Validate manually — …`, `Evidence next - …`). Build Order objects and direct bridge/envelope sections can use matching camel/snake-case keys such as `continueFirst`, `evidenceNext`, `validateManually`, `manualProof`, `holdForLater`, and `setAside`. Those section values may be arrays, a single candidate object, or a reader-friendly string/newline list; Ranker splits scalar sections into candidate actions so Scattermind does not have to wrap every lane in arrays. Ranker maps those to `doFirst / validateNext / defer / park` while preserving the softer original label in `sourceQuote` or candidate source trace. Ranker also accepts softer continuation envelopes named `rankerBridge`, `continuation`, or `continuationPlan`, candidate arrays named `possibleNextMoves`, `suggestedNextMoves`, `recommendations`, or `opportunities`, laned `buildOrderPreview` / `build_order_preview` objects, first-48-hour action arrays (`next48Hours`, `next_48_hours`, `first48Hours`, `first_48_hours`, `nextTwoDays`, `next_two_days`), and evidence-question fallback arrays (`evidenceQuestions` / `evidence_questions`, `proofQuestions` / `proof_questions`, `validationQuestions` / `validation_questions`, `decisionQuestions`, `questionsToAnswer`, `followupQuestions`). Direct candidate objects may use reader-friendly prose keys like `text`, `content`, `summary`, `step`, `task`, `instruction`, `why_it_matters`, `evidence_to_collect`, `first_proof_step`, `green_flag`, and `red_flag`; Ranker normalizes those into title, value, evidence, next-step, success, and kill-signal fields so Scattermind does not have to rename paid Concept Map language into software-feature jargon. If a paid Concept Map has no labelled Build Order/action threads but does include `closing_note` / `closingNote` plus decision questions, Ranker treats the closing note as the active 48-hour Do first move and keeps the questions in Validate next. This lets Scattermind pass reader-friendly Concept Map copy without renaming everything into software-feature language.

 Lane safety note: explicit Scattermind `defer` / `park` hints are hard rails, not mild suggestions. Source `nonGoals` / `avoid` guardrails are also hard enough to keep conflicting candidates out of Do first / Validate next even when their local scoring hints look attractive; soft guardrail language such as “this is not a dashboard” or “keep auth/billing/workspaces out until proof” is promoted into non-goals, not merely background context. Ranker now also infers a light `ideaRoute` from the Scattermind source text and carries it in `input.decisionContext` / `handoff.decisionContext`; for game concepts it automatically adds anti-SaaS non-goals so account/dashboard/workspace/subscription candidates cannot win a playable-prototype build order just because they were phrased loudly. The result will mark the lane source as `source-non-goal` so the handoff can explain that the candidate needs guardrail resolution before active work. Handoff `source.requiresSourceTrace` is true only when a real source artifact/title is present; plain idea-only ranking still warns about a missing artifact ID when it carries prompt provenance, but it does not spam source-section/evidence warnings meant for Scattermind artifacts. Handoff `readiness` now gives downstream bridge consumers a deterministic gate: `ready`, `usable-with-warnings`, `needs-source-context`, or `blocked`, with blockers and next checks for missing evidence, source trace, duplicate IDs, or active source-non-goal conflicts. Handoff `activeSlice` (`ranker-active-slice-v1`) is the compact machine-readable continuation unit: one active item, its proof/evidence/success/kill signals, source anchor, held-back items, readiness status, and the rule that only this slice is build-ready. For tired first-screen users, `brief.decisionReceipt` repeats the one active move, first proof step, evidence question, held-back items, source anchor, and the handoff rule that only Do first is active; use it as the compact result strip before showing the full lane board. For low-friction handoff, `/api/rank-feedback` also detects a raw Scattermind/Concept Map JSON object pasted into `idea`, `ideaText`, `optionsText`, or wrapper keys such as `payload`; it expands that object before ranking and reports `input.embeddedPayloadSource` so the public form can accept copy/paste exports without a custom import screen. Exact free Snapshot JSON (`working_name`, `restated_idea`, `lenses.shape`, `questions_to_sit_with`, `reference_code`) is rankable too: Ranker derives a manual proof active slice plus evidence questions, carrying the Snapshot reference code/title into provenance so a Snapshot-only handoff does not need a paid Concept Map before it can produce a useful build order. If a Concept Map only carries `questions_to_sit_with` / `questionsToSitWith` / `openQuestions` and no explicit build-order lanes or action threads, Ranker converts those questions into Validate-next evidence actions with source trace instead of pretending they are software features.
