Make the dialogue/utterance editor vertical, matching the mystery graph

Input on top, output on the bottom, exit sinks in a row below; wires flow
downward. Cards auto-expand, so their heights are measured (offsetHeight) to
place the bottom output port. Seed and Tab-created utterances now stack downward.

+With the development PostgreSQL container running, exercise the migration ledger and persistence API against uniquely named disposable databases:

+
+The smoke harness builds the application, creates a disposable PostgreSQL database and level, exercises move, hand-pan, desktop wheel zoom, mobile touch pinch, folder expansion, file movement, and reload persistence, then removes the test database.

+The browser suite also imports and solves the bundled Glass Harbor mystery against that disposable database. Mystery manifests are database-authoring content rather than compiled frontend cases; see [`mysteries/README.md`](mysteries/README.md).
+
 ## Data and API
 
 The server stores its tables and migration ledger in the dedicated `osint` schema of PostgreSQL. `DATABASE_URL` is required.
 
 The accepted model stores each playable or editable level as an isolated mutable board of normalized exhibits. Immutable template-version boards are cloned to create levels, and mutable levels can be cloned back into new template versions. Assets remain immutable and reusable across those copies.
 
-The running POC still uses the earlier `widgets` and `playthrough_*` tables while the exhibit-schema cutover is prepared. They are explicitly transitional; new domain concepts should follow the exhibit model rather than extending those tables.
+The running POC uses the canonical exhibit schema directly. The earlier JSON case store, `widgets`, and `playthrough_*` tables were removed in migration 006.
 
 The API surface is:
 
 - `GET /api/levels`
 - `POST /api/levels` (editor only)
+- `GET /api/templates`
+- `POST /api/templates/:slug/levels` (instantiate a version; editor only)
 - `GET /api/levels/:id`
 - `PUT /api/levels/:id`
 - `POST /api/levels/:id/reset`
+- `POST /api/levels/:id/templates` (save a new immutable version; editor only)
+- `POST /api/levels/:id/documents` (editor only)
+- `GET /api/assets/:id`
+- `GET /api/session` (verified session and admin capability summary)
 - `GET /api/health`
 
 The browser also keeps a local emergency copy so a network interruption does not lose an in-progress board.
 
 ## Level editor
 
-Set `LEVEL_EDITING_ENABLED=true` and open `/?edit=1`. If the database is empty, this surface creates the first blank level. The target model intentionally makes editing and playing the same operation against a mutable level; authoring additionally exposes “save as template”. The current playthrough overlay remains only until the exhibit-schema migration is complete.
+Set `LEVEL_EDITING_ENABLED=true` and open `/?edit=1` while signed in with a JWT carrying `role: "admin"`. The shared `auth_token` cookie is verified with `JWT_SECRET`; the legacy `isAdmin: true` claim remains compatible. If the database is empty, this surface creates the first blank level. Editing and playing are the same operation against a mutable level. Authoring actions live under the **Admin** menu. Saving a template creates a new immutable version; instantiating gives every exhibit a fresh ID while sharing immutable binary assets. Reset restores the exact template version from which a level was created.
+
+For the standalone development Compose stack, visit `/api/dev/admin-session?returnTo=/?edit=1` once to receive a local signed admin cookie. This helper does not exist in production.
 
 In edit mode, files can be dragged from the desktop onto the board or selected with **Import Document**. Images, PDFs, and text files render inside document windows; unknown formats remain downloadable source files. Extracted evidence becomes an editable folder widget. Its editor controls the title, annotation, contained documents, and each source document's publication time. The default upload limit is 25 MB and can be changed with `MAX_DOCUMENT_BYTES`.
 
-Production defaults editing to disabled. Set `LEVEL_EDITING_ENABLED=true` in `/opt/gu_common/.env.prod` only when the authoring surface should be available. This is a capability switch, not authentication; add authentication before exposing production editing to untrusted users.
+Production defaults editing to disabled. Set `LEVEL_EDITING_ENABLED=true` in `/opt/gu_common/.env.prod` only when the authoring surface should be available. `JWT_SECRET` is inherited from that shared environment, and authoring endpoints additionally require a verified admin claim.
 
 ## POC exhibit and widget contract
 
@@ -64,19 +98,25 @@ The current POC defines four exhibit families and corresponding frontend widgets
 - **Folder** — a titled, annotated collection. Opening it expands its contained source files to their saved relation-bound board positions; closing it retracts and hides them.
 - **Source file** — immutable binary evidence plus user-editable title, publication time, file type, and arbitrary key/value metadata. Image is the first fully visual file renderer. PDF, web capture, email, article, filing, price list, text, and generic file are registered types with a generic fallback until their renderers are built.
 - **Note** — investigator-authored interpretation, visually distinct from source evidence.
-- **Event** — an investigator-authored “this happened” statement with narrative text, an occurrence time, and normalized links to its supporting evidence. Chronologically ordered events become the emerging story.
+- **Event** — an investigator-authored “this happened” statement with narrative text, an occurrence time, and normalized links to supporting exhibits. The editor manages citations, dashed support lines keep them visually distinct from red investigative thread, and chronologically ordered events form the reconstructed-story strip.
 
-The planned **Party** family adds distinct Person and Organization exhibits (businesses are organizations). Their dossier-like widgets reveal normalized evidence associations, but parties remain identity objects rather than special folders.
+The **Party** family has distinct Person and Organization subtypes (businesses are organizations). Names begin as concepts in the level brief. The investigator classifies each concept, which creates the appropriate dossier exhibit and records the resolution. Expected classifications remain author-only. Dossiers store aliases and normalized evidence associations, but parties remain identity objects rather than special folders.
+
+**Red thread** is a normalized connection between any two exhibits, including expanded source documents. Each connection may carry an investigator-authored relation tag, a persisted tightness percentage, and a presentation choice. `LUGGAGE` reuses the investigator note's expressive hanging tag, rotating to read before opening the editor; `COMPACT` keeps the original knot-and-label treatment and opens the editor directly. Both remain available while the POC establishes which works best. When a connected source document is retracted into its folder, the visible endpoint follows it to the folder until it is expanded again.
 
 Folder ownership is stored as a normalized membership. The contained document exhibit owns its expanded `xpos` and `ypos`. For deterministic collapse behavior, one exhibit has at most one owning folder; two exhibits may reuse the same immutable asset when the same source file must appear in multiple folders.
 
 An open folder draws a pale red containment band to each expanded file. Each dated file independently projects a grey line to the temporal index. This allows the player to arrange files until those grey lines are vertical, close the folder, and later reopen the same arrangement.
 
-The frontend widget registry maps an exhibit type, and optionally a document type, to its React visualization. Widgets do not own investigation-domain data.
+The timeline uses an optional board-level start and end date. Click **Timeline** in the menu or the displayed range in the footer to adjust it; **Use Automatic Range** returns to evidence-derived bounds. Configured bounds are normalized board data and follow template cloning and reset. Evidence outside the visible interval remains available and is pinned to the nearest timeline edge.
+
+The typed frontend widget registry maps each exhibit type, and each document type, to its React visualization. Adding a domain type now produces a compile-time requirement to register its renderer. Widgets do not own investigation-domain data.
+
+On desktop, an ordinary mouse wheel or two-finger trackpad scroll zooms the board. Desktop pinch gestures are consumed so they cannot zoom both the browser and board. Touch devices use a two-finger pinch on the board; toolbar controls remain available on every device.

+## Milestone 5: claim-driven case report
+
+The purpose of this milestone is the gameplay loop, not a knowledge graph: the player connects two exhibits, explains that one specific thread with a luggage-tag Claim, and later discovers that their accumulated explanations have become a nearly complete case report.
+
+### 5.1 Lock the gameplay and temporal rules
+- [ ] Define a Claim as an entity owned by exactly one investigative thread; a thread has zero or one Claim. (The text associated with a claim can prove multiple points, handed by the text.
+- [ ] Keep untagged threads as ordinary connections that do not appear in the report.
+- [ ] Use the same Claim text on the luggage tag and in the report. Editing either presentation updates the same database value.
+- [ ] Derive the Claim date from the earliest non-null temporal date of its two endpoint exhibits; never use `created_at` or the current time.
+- [ ] Use Event `occurred_at` and a Document's primary timeline date as direct endpoint dates. For a Folder, use the earliest dated contained Document. Leave a Claim undated when neither endpoint supplies a date.
+- [ ] Place undated Claims after dated Claims in the initial report order while keeping them fully editable and reorderable.
+- [ ] Treat the derived date as the initial chronological suggestion only. Manual report ordering must not rewrite exhibit or Claim dates.
+### 5.2 Add normalized persistence
+
+- [ ] Add a `claims` table with a unique foreign key to `exhibit_connections`, text, tag style, position percentage, lateral offset, and timestamps.
+- [ ] Move luggage-tag-specific text and placement fields out of `exhibit_connections`; retain curve tightness and endpoints on the connection.
+- [ ] Add one level-owned `case_report` and normalized `case_report_claims` rows with explicit `sort_order`.
+- [ ] Assign stable, level-local display numbers to cite exhibits as `Exhibit 3` independently of board position, z-index, or report order.
+- [ ] Enforce same-board ownership for the Claim's connection, both endpoint exhibits, report, and report membership.
+- [ ] Delete a Claim and its report membership transactionally when its luggage tag is removed, while retaining the now-untagged thread.
+- [ ] Delete both the Claim and connection when the thread itself is removed.
+- [ ] Clone board-owned Claims with fresh IDs during template creation and instantiation; rebuild level report membership against the cloned Claim IDs.
+- [ ] Make reset discard player-created Claims and restore exactly the Claims present in the source template version.
+- [ ] Keep uploaded binary evidence in MinIO. Reports and Claims reference Document exhibits and asset metadata; they never duplicate or embed asset bytes.
+
+### 5.3 Expose a focused API contract
+
+- [ ] Add a typed Claim DTO to an investigative connection instead of exposing a free-form connection `label`.
+- [ ] Return each Claim's derived date and its two stable exhibit citations in the report response.
+- [ ] Add granular operations to create, edit, and remove a Claim without replacing the complete board state.
+- [ ] Add a report endpoint that returns ordered Claim rows and an atomic reorder operation.
+- [ ] Reject empty Claim text, invalid connection ownership, duplicate Claims on one connection, and report orders containing foreign or duplicate Claim IDs.
+- [ ] Protect Claim and report writes with the board revision so concurrent saves cannot silently overwrite reasoning.
+
+### 5.4 Turn luggage tags into Claim widgets
+
+- [ ] Change the thread prompt from “Add tag” to “Explain this connection,” with a secondary option to leave the thread untagged.
+- [ ] Create the Claim and its luggage-tag presentation in one interaction, preserving the current tightening animation.
+- [ ] Keep both `LUGGAGE` and `COMPACT` as visual presentations of the same Claim entity while playtesting them.
+- [ ] Preserve draggable percentage and tension-constrained lateral offset as Claim presentation state.
+- [ ] Rename tag-oriented frontend types and commands to Claim terminology without changing the established visual design.
+- [ ] Give a newly created Claim a subtle “added to report” ink animation or badge without interrupting board work.
+
+### 5.5 Build the typewriter case report
+The end goal is that a case report is prepopulated by the claims the player made during the investigation so that a skeleon of the case solution is present. The player must simply edit the case report and submit it. 
+
+- [ ] Add **Case Report** as a primary menu item and implement it as a persistent board view, separate from exhibits and the timeline.
+- [ ] Provide an empty state that explains that explaining red threads will create the report, without revealing a solution or forcing a tutorial.
+- [ ] Initially arrange Claim rows chronologically by derived date, using the order parameters on the claim as tie-breaker and undated Claims last, below a horizontal rule that says (missing date)
+- [ ] Render each row as a typewritten Claim with its date and endpoint citations, for example: `14.10.1987 — Maria Voss redirected the shipment. Exhibits 4 and 7.`
+- [ ] It needs to be possible to add free text before and after the claims. Coloured inline text (use span elements)  have a specific class and id can be edited
+- [ ] -Make Claim text editable inline. Persist through the Claim API so the luggage tag updates immediately.
+- [ ] Support pointer and keyboard reordering of Claim rows and persist the resulting explicit report order into order column of the claim. 
+- [ ] Clicking a Claim must minimize the report as appropriate, center its thread, and briefly illuminate the curve and luggage tag.
+- [ ] Clicking an exhibit citation must locate and highlight that exhibit using the existing tray/board locator treatment.
+- [ ] Ensure the report is legible and operable on portrait mobile layouts as well as desktop.
+- [ ] Add restrained typewriter, paper, and ink feedback while respecting reduced-motion preferences.
+
+### 5.6 Test the reasoning loop
+
+- [ ] Unit-test endpoint date resolution for Event, Document, Folder, partially dated, fully undated, and invalid-date cases.
+- [ ] Migration-test the one-Claim-per-thread constraint, cascading behavior, same-board enforcement, and report ordering constraints.
+- [ ] Integration-test create/edit/remove Claim, two-way text synchronization, report reorder, reload persistence, reset, and template cloning.
+- [ ] Verify that Claims citing uploaded Document exhibits survive cloning while their immutable assets remain shared through MinIO.
+- [ ] Add a browser test that creates several connections out of chronological order, explains them, opens the report, edits and reorders the Claims, then returns to each highlighted thread.
+- [ ] Play the Glass Harbor mystery using Claims as the primary reasoning mechanism and record whether the generated report makes the conclusion emerge naturally.
+- [ ] Revise prompts, animation, initial ordering, and report typography based on that playtest before adding automated evaluation.
+
+### 5.7 Deliberately deferred
+
+- [ ] Design a hidden, template-versioned solution rubric only after the deterministic Claim/report loop is enjoyable and dependable.
+- [ ] Add LLM report evaluation as a later milestone with structured citations, calibrated uncertainty, and reproducible evaluator output.
+- [ ] Do not add general-purpose semantic edge roles, Claim hubs, Claim-to-Claim links, or a knowledge-graph ontology as part of this milestone.
+
+### Milestone 5 definition of done
+A player can connect exhibits, explain each connection with a luggage-tag Claim, discover those exact words in a chronological typewriter report, improve and reorder the Claims, follow every citation back to the board, reload without loss, and reset safely to the template. No LLM is required for this experience to work.

+# First slice: splash → New Game → briefing → board
+
+Scope: the thinnest end-to-end narrative thread. A player lands on a
+**PRINCIPAL INVESTIGATOR** splash, clicks **New Game**, watches one scripted
+briefing cutscene from the Glitch University professor (with a pose swap), and
+arrives on the existing Glass Harbor board. Identity is a hard-coded test user.
+All cutscene content is authored through the manifest importer — nothing
+hard-coded in React.
+
+Explicitly **out of scope** for this slice: the admin authoring panel, multiple
+chapters, the debrief/back-to-board scenes, dialogue branching, and any LLM. The
+schema below only reserves those (`kind`, nullable `advances_to`) — it does not
+build them.
+
+## Ordered tasks
+
+### 1. Identity: hard-coded test user (do this first)
+- [ ] Add `resolveUserId(req)` to `server/auth.ts`: return `authClaims.sub` when
+  present, else a single fixed dev `TEST_USER_ID`. Leave `requireAdmin` and the
+  symmetric-secret admin path untouched.
+- [ ] Note in code that the external `glitch.university` key-exchange path
+  replaces only the fallback branch later; the `user_id` column does not change.
+
+### 2. Migration `015_narrative_layer.sql`
+Minimal tables to run one scripted scene against one chapter.
+- [ ] `mysteries (id, slug UNIQUE, title)` and `mystery_chapters (mystery_id,
+  chapter_index, level_template_version_id, PK (mystery_id, chapter_index))`.
+- [ ] `npcs (id, mystery_id, name, role, default_pose_key)`.
+- [ ] `poses (id, npc_id, pose_key, asset_id → osint.assets, UNIQUE (npc_id,
+  pose_key))`.
+- [ ] `cutscenes (id, mystery_id, chapter_index NULLABLE, slot, title)`.
+- [ ] `dialogue_steps (id, cutscene_id, step_key, sort_order, npc_id, pose_key,
+  kind DEFAULT 'scripted', text, advances_to NULLABLE, UNIQUE (cutscene_id,
+  sort_order))`.
+- [ ] `playthroughs (id, user_id, mystery_id, current_chapter_index,
+  current_level_id, created_at)`.
+- [ ] `seen_dialogue (playthrough_id, cutscene_id, seen_at, PK (playthrough_id,
+  cutscene_id))`. (Cutscene-level for the slice; step-level deferred.)
+
+### 3. Repository (`server/narrativeRepository.ts`, or extend levelRepository)
+- [ ] `createPlaythrough(userId, mysterySlug)`: instantiate chapter 1's template
+  version into a fresh level (reuse `instantiate_template_version`), insert the
+  playthrough, return it.
+- [ ] `getCurrentPlaythrough(userId)`: newest unfinished playthrough for the user.
+- [ ] `getPendingCutscene(playthrough)`: earliest unseen cutscene matching the
+  current slot/chapter, with steps joined to NPC + resolved pose asset URL.
+- [ ] `resolvePose(npc, poseKey)`: pure, unit-testable — requested `pose_key` →
+  NPC `default_pose_key` → `null` (no artwork). Return the asset URL or null.
+- [ ] `markCutsceneSeen(playthroughId, cutsceneId)`: idempotent insert.
+
+### 4. API (`server/index.ts`), all scoped to `resolveUserId(req)`
+- [ ] `POST /api/playthroughs` → create for the user, returns playthrough +
+  `pendingCutscene` + current level id.
+- [ ] `GET /api/playthroughs/current` → the user's playthrough or 204/empty.
+- [ ] `POST /api/playthroughs/:id/cutscenes/:cutsceneId/seen` → idempotent; 403 if
+  the playthrough's `user_id` is not the caller.
+
+### 5. Manifest importer (content path)
+- [ ] Extend `MysteryManifest` in `scripts/importMysteryTemplate.ts` with `cast[]`
+  (NPCs, each with `defaultPose` and `poses: { pose_key → asset path }`) and
+  `cutscenes[]` (`{ slot, chapter?, steps: [{ npc, pose, text }] }`).
+- [ ] Freeze a `mysteries` row + one `mystery_chapters` entry pointing at the
+  Glass Harbor template version, plus the cast and the intro cutscene, through the
+  same authenticated operations already used for assets.
+- [ ] Tolerate a cast with **no pose images** (author an NPC with just a name/role
+  so the slice runs art-free); upload images only if the manifest provides them.
+- [ ] Add a `mystery_intro` cutscene to `mysteries/glass-harbor/mystery.json`: the
+  professor briefing, 3–5 scripted steps, referencing pose keys that may not exist
+  yet (fallback handles it).
+
+### 6. Frontend
+- [ ] `SplashScreen`: title **PRINCIPAL INVESTIGATOR** over "Glitch University" in
+  the existing boot aesthetic; **New Game** always, **Resume** when `current`
+  returns a playthrough.
+- [ ] `DialogueOverlay`: render `pendingCutscene` steps; portrait from the
+  resolved pose (fallback to name+text when null); advance on click/Space/Enter;
+  typewriter with instant-reveal on first press; `prefers-reduced-motion`
+  respected; on finish call `…/seen` then reveal the board.
+- [ ] App boot: `GET …/current` → no playthrough shows splash; New Game POSTs,
+  loads the returned level (reuse existing level fetch/render), and plays
+  `pendingCutscene` before handing control to the board.
+
+### 7. Tests
+- [ ] Unit: `resolvePose` across requested / default / none; `getPendingCutscene`
+  returns only unseen scenes.
+- [ ] Integration: New Game creates a playthrough bound to the test user;
+  `current` returns it; `seen` is idempotent; a second user id cannot read or mark
+  the first user's playthrough.
+- [ ] Integration: importing the extended manifest freezes the NPC + intro
+  cutscene, and a New Game surfaces exactly those steps.
+- [ ] (Optional) Browser smoke: splash → New Game → overlay appears and advances →
+  board visible; reload does not replay the seen briefing.
+
+## Definition of done (slice)
+Against the test user, New Game creates a playthrough, the professor's scripted
+briefing plays with a pose swap (or clean name+text when art is absent), the Glass
+Harbor board loads, and a reload resumes without replaying the briefing — with the
+cutscene authored via the manifest, not hard-coded.
+
+## Open defaults (flag before coding if you disagree)
+- Second New Game **resumes** an unfinished playthrough (explicit Restart), rather
+  than always starting fresh.
+- `seen_dialogue` is **cutscene-level**, not step-level (no mid-scene resume yet).
+- One migration `015` holds all slice tables rather than several.

+# Narrative layer: campaigns, NPC cutscenes, and authoring
+
+This roadmap covers the narrative layer end to end: the **campaign** that chains
+levels into a mystery, the **NPCs / poses / cutscenes** the player watches
+between levels, and the **admin authoring panel** that lets a game designer build
+all of it in-app. Work generally proceeds top to bottom.
+
+**Design intent.** These mysteries are real-world scam cases that must actually be
+investigated to be understood. Such cases cannot be simplified, they 
+can only be staged for didactic discovery into levels.
+
+The LLM is not a decoration on the cutscenes — it
+is a **cognitive shim**: the assistant that keeps a player oriented as case
+complexity grows. A player can use this feature many times, but some very bright
+players might get it right on the first go. 
+This is what lets a mystery be as intricate as the real case
+demands without the player getting lost. The scripted narrative layer below is the
+delivery channel and the fallback; the LLM is the layer that scales comprehension.
+Section 9 is deferred in build order but primary in intent, so the model is shaped
+now to accommodate it (the `generated` step kind, the read-only context contract,
+and the authored case model).
+
+## Working agreement
+
+- All narrative content — campaigns, NPCs, poses, cutscenes, dialogue text — is
+  authored template data frozen through supported operations. None of it is
+  hard-coded into React components or SQL seed literals. The exception to this rule is 
+  custom cutscenes (react components) which are registered as components and referenced by the node.
+- The admin panel is a GUI over the **same** operations available to the manifest
+  importer; both paths freeze the same immutable template data.
+- A cutscene never mutates a board. The professor's scene *narrates* the new
+  document and goal; those exhibits and the updated brief already live in the
+  next chapter's template.
+- A narrative behavior is complete only when its PostgreSQL representation, API
+  behavior, frontend presentation, persistence, and focused tests agree.
+- Pose portraits are immutable shared bytes, stored and cloned exactly like
+  document image assets (MinIO + `objectStorage`); scenes reference assets, they
+  never duplicate them.
+
+## First vertical slice: "The Glass Harbour Diversion"
+
+Build the smallest end-to-end narrative loop before generalizing. Ship these in
+order; each is playable on its own.
+
+- [ ] Add the **splash screen** — "PRINCIPAL INVESTIGATOR", Glitch University —
+  with a single **New Game** action that creates a playthrough and launches the
+  first scene (sections 1, 6, 7).
+- [ ] Create a mystery named **The Glass Harbour Diversion** as a one-chapter
+  campaign wrapping the existing Glass Harbor level template (sections 1–2).
+- [ ] Add a **briefing NPC** (the Glitch University professor) and a
+  `mystery_intro` cutscene that briefs the player, using at least two poses to
+  prove pose-per-utterance (sections 2–3, 7).
+- [ ] Wire the briefing to play once on load and mark itself seen, then reveal the
+  first level's board (sections 1, 6, 7).
+- [ ] Author **two `level_debrief` end-scenes** the player reaches by reporting
+  back: one that **sends them back to the board** and one that **concludes the
+  mystery**. Model these as two end-of-scene outcomes (buttons), not branching.
+- [ ] Leave the back-to-board scene as **scripted** for now, but author it as a
+  `generated`-ready step (section 9) so the professor's hint can later be produced
+  from the player's Case Report explanation.
+
+## 1. Campaign / progression backbone
+
+- [ ] Define a **cutscene** node as something a) references a custom react component. 
+  That react can use potential **utterances** such that for example, it can play 
+  an ordered sequence utterance that brief the player: `(speaker NPC, pose, text)`. 
+  A node can be marked has_utterances which permits the admin user to add utterances in order.
+  [ ] A dialogue is another type of node that invokes the standard NPC dialogue component. This
+  has utterances, and consist of a graph where utterances either are spoken by the NPC or available for selection.
+  Example :  if the NPC utters "Are you ready?" this has two child utterances marked "player" which could be "yes" and no. The user may select these. "No" could in principle point back to the same utterance and "yes" to the next. If an utterance has a non NULL terminal id, then the game advances to the node pointed to by that terminal. Available terminals are only those who have the current dialogue node as it parent.
+- [ ] There exists "det_gate" nodes and "llm_gate" nodes. We begin with the deterministic gate only. The end result of a level is sent to a "det_gate". The det gate can inspect the output of the level and determine if the story should advance through one of its terminals. For now, the det-gate always returns the happy path terminal leading to the mystery being solved.
+
+## 2. NPC and pose catalog
+
+- [ ] Add an **NPC** entity (display name, short role e.g. "Glitch University
+  professor", default pose) owned by the mystery/template family, so casts are
+  authored rather than global magic strings.
+- [ ] Add **poses** as named portrait variants of an NPC (`pose_key` such as
+  `neutral`, `concerned`, `wry`, `pointing`), each backed by one immutable image
+  asset via the existing `assets` table + MinIO path.
+- [ ] Clone NPCs and pose→asset references (asset bytes reused, not copied) during
+  template freeze and instantiation, mirroring document image cloning.
+- [ ] Enforce that every dialogue step names an NPC that exists in the mystery's
+  cast; a **missing pose is never an error**.
+- [ ] Resolve a step's portrait at render time with graceful fallback: the
+  requested `pose_key`, else the NPC's **`default`** pose, else **no artwork**
+  (speaker name + text only). This lets authors add poses incrementally and keeps
+  the first slice playable with zero uploaded art.
+
+## 6. API contract
+
+- [ ] **New Game / session:** add `POST …/playthroughs` (create for the current
+  `user_id`, per section 1) and `GET …/playthroughs/current` so the splash can
+  offer New Game or Resume; scope every playthrough read/write to the caller's
+  `user_id` so one player cannot touch another's game state.
+- [ ] **Play mode:** return a compact `pendingCutscene` payload (slot, ordered
+  steps with resolved NPC name + pose asset URL) when one is due and unseen; add
+  `POST …/playthroughs/:id/cutscenes/:cutsceneId/seen` (idempotent) and
+  `POST …/playthroughs/:id/advance` implementing section 1's transactional advance.
+- [ ] **Admin mode:** add authenticated CRUD for mysteries, chapter ordering,
+  NPCs and poses, and dialogue scenes/steps, plus the campaign freeze operation —
+  all behind the existing admin JWT and `edit=1` gate.
+- [ ] Keep authoring-only fields (raw pose keys, expected-solution data, unfrozen
+  drafts) out of play-mode responses, consistent with how brief concept
+  `expectedPartyKind` is already hidden in play mode.
+
+
+## Definition of done
+
+A game designer can, in the admin panel, create a mystery, select existing levels
+as ordered chapters, create NPCs and upload named poses, craft dialogue scenes
+choosing a pose per step, and attach those scenes to chapter slots — then freeze
+it. A player lands on the "PRINCIPAL INVESTIGATOR" splash, chooses New Game to
+create a playthrough bound to their identity, watches the professor speak
+line-by-line with a
+changing portrait, investigates each board, reports back to advance a chapter that
+introduces a new document and goal, and reloads at any point without replaying
+seen scenes — with no dialogue text hard-coded in React and no cutscene mutating a
+board.

+# Story flow graph: the mystery editor
+
+Status: **implemented** (migrations `018`–`021`). A mystery plays as a walk of an
+authored node graph; the slot/chapter model has been retired in a clean cutover.
+Gates are stubbed and the LLM gate is not built (see *Implemented vs deferred*).
+Builds on the NPC/dialogue work in [narrative-todo.md](narrative-todo.md).
+
+## Concept
+
+A mystery is a **directed graph of nodes**. Each node has one implicit input and N
+output **terminals**; a terminal carries its single outgoing wire (`to_node_id`) —
+there is no separate edges table. A playthrough walks the graph from the mystery's
+single **entrypoint node** (`mysteries.entry_node_id`).
+
+- At the **node level** cycles are allowed (a gate can route back to a level). The
+  runtime only advances a node when the player acts, so loops never spin on their own.
+- Within a **dialogue node** the utterances form a **tree** (each utterance has one
+  parent), so back-edges/loops are not expressible there yet.
+
+## Node types
+
+| type | what it does | terminals |
+|---|---|---|
+| `cutscene` | Renders a bespoke React component chosen from a frontend registry (`component_key`), e.g. a title card. Opaque to the graph so set-pieces don't clutter the dialogue tree. | usually 1 (`continue`) |
+| `dialogue` | The standard NPC dialogue box, driven by an utterance tree (NPC lines + player choices). | 1+ (e.g. `continue`, or `proceed`/`retry` for a branch) |
+| `level` | Instantiates a playable board from a level template version and hands over to the investigation. | 1 (`report_back`) |
+| `det_gate` | Deterministic gate. **Currently a stub**: auto-follows its first terminal. Intended to inspect the previous node's output (a level's case report, a dialogue's chosen path) and route accordingly. | 1+ |
+| `llm_gate` | LLM gate — **not implemented**. Intended: read allowlisted player state, return one terminal key (constrained output). | 1+ |
+
+Gates are resolved server-side during `advance` and never surfaced to the player.
+
+## Data model
+
+Two core tables plus `utterances`; type-specific scalars are folded onto the node
+(kept honest by CHECKs) rather than in per-type subtype tables.
+
+```sql
+CREATE TABLE osint.story_nodes (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  mystery_id UUID NOT NULL REFERENCES osint.mysteries(id) ON DELETE CASCADE,
+  node_type TEXT NOT NULL CHECK (node_type IN ('cutscene','dialogue','level','det_gate','llm_gate')),
+  label TEXT NOT NULL DEFAULT '',
+  has_utterances BOOLEAN NOT NULL DEFAULT FALSE,
+  xpos DOUBLE PRECISION NOT NULL,
+  ypos DOUBLE PRECISION NOT NULL,
+  -- Folded, type-specific scalars. Nullable during authoring; "required for type"
+  -- is a publish-time concern, so only these exclusion CHECKs are enforced.
+  level_template_version_id UUID REFERENCES osint.level_template_versions(id),
+  component_key TEXT,  -- cutscene: frontend component; gate: (future) backend gate fn
+  CHECK (level_template_version_id IS NULL OR node_type = 'level'),
+  CHECK (component_key IS NULL OR node_type IN ('cutscene','det_gate','llm_gate'))
+);
+
+-- Output ports. A terminal owns its single outgoing wire; no edges table.
+CREATE TABLE osint.story_node_terminals (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  parent_node_id UUID NOT NULL REFERENCES osint.story_nodes(id) ON DELETE CASCADE,
+  terminal_key TEXT NOT NULL,
+  label TEXT NOT NULL DEFAULT '',
+  to_node_id UUID REFERENCES osint.story_nodes(id) ON DELETE SET NULL, -- NULL = unwired/end
+  sort_order INTEGER NOT NULL DEFAULT 0,
+  UNIQUE (parent_node_id, terminal_key)
+);
+-- Same-mystery integrity for to_node_id is enforced in the repository (not a
+-- DB trigger). entry_node_id is nullable so nodes can be inserted before it is set.
+ALTER TABLE osint.mysteries ADD COLUMN entry_node_id UUID REFERENCES osint.story_nodes(id) ON DELETE SET NULL;
+```
+
+### Utterances — a dialogue node's content
+
+One table for both NPC lines and player choices, distinguished by `utterer`.
+
+```sql
+CREATE TABLE osint.utterances (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  node_id UUID NOT NULL REFERENCES osint.story_nodes(id) ON DELETE CASCADE,
+  utterer TEXT NOT NULL DEFAULT 'npc' CHECK (utterer IN ('npc','player')),
+  npc_id UUID REFERENCES osint.npcs(id),   -- speaker for NPC lines; NULL for player choices
+  pose_key TEXT,                            -- resolved with the usual pose fallback
+  text TEXT NOT NULL DEFAULT '',
+  parent_utterance_id UUID REFERENCES osint.utterances(id) ON DELETE CASCADE,       -- the utterance this one follows
+  advances_to_utterance_id UUID REFERENCES osint.utterances(id) ON DELETE SET NULL, -- VESTIGIAL / unused (see below)
+  terminal_id UUID REFERENCES osint.story_node_terminals(id) ON DELETE SET NULL,    -- exit: leave the node via this terminal
+  effect TEXT,                              -- reserved side-effect hook (unused)
+  xpos DOUBLE PRECISION NOT NULL DEFAULT 0, -- position in the utterance sub-canvas
+  ypos DOUBLE PRECISION NOT NULL DEFAULT 0,
+  sort_order INTEGER NOT NULL DEFAULT 0
+);
+```
+
+**The model is parent-only with count-based meaning.** An utterance's *children*
+(the utterances whose `parent_utterance_id` points to it) are what come after it:
+
+- **0 children** + `terminal_id` set ⇒ this line **exits** the node via that terminal.
+- **1 child** ⇒ **linear** next line (rendered as a solid wire).
+- **2+ children** ⇒ **player options** (rendered as dotted wires); by convention the
+  children are `player` utterances and the parent is an NPC prompt.
+
+The root of a node's tree is the utterance with no parent. `advances_to_utterance_id`
+is a leftover column from an earlier design and is **not used**; a follow-up
+migration can drop it. Because each utterance has a single parent the graph is a
+tree — no back-edges/loops within a node yet.
+
+### Cutscene component registry (frontend)
+
+Mirrors the exhibit registry: `component_key → React component`. Each owns its
+presentation and signals completion with an optional terminal key.
+
+```ts
+type CutsceneComponent = React.FC<{ onComplete: (terminalKey?: string) => void }>
+// registry: { 'glass-harbour-diversion': GlassHarbourDiversion }
+```
+
+For a single-terminal cutscene, `onComplete()` follows the only terminal.
+
+## Editing UX
+
+The same canvas engine (pan, zoom, drag, curved wires, click-a-wire-to-delete) is
+reused at two levels.
+
+**Mystery graph** — `story_nodes` as cards, wired by `terminal.to_node_id`. Laid out
+**vertically**: the input port is on **top**, output terminals along the **bottom**,
+and flow runs downward. Double-clicking a dialogue node drills into its utterances.
+
+**Utterance crafter** — a dialogue node's utterances as draggable cards; the node's
+output terminals appear as **exit sinks** docked to the right. Each card has one
+output port:
+
+- Drag a card's port to another card ⇒ that card becomes a **child** (1 child = solid
+  linear; 2+ = dotted options).
+- Drag to an exit sink ⇒ the card leaves the node via that `terminal_id`.
+- **Tab** on a selected utterance adds a child (a lone child stays a linear NPC line;
+  a second flips them to player options). **1** / **2** set the selected card's
+  speaker. **Ctrl/Cmd+Z** undoes connection/creation edits. Cards colour by speaker
+  and auto-expand to full text.
+
+## Runtime traversal
+
+The playthrough tracks position with `current_node_id` (and `current_level_id`,
+set while on a level node); the slot fields were dropped.
+
+```sql
+ALTER TABLE osint.playthroughs ADD COLUMN current_node_id UUID REFERENCES osint.story_nodes(id) ON DELETE SET NULL;
+```
+
+- **New Game** creates a playthrough at the entrypoint (bound to the JWT identity,
+  with a dev test-user fallback).
+- **`getCurrentPlaythrough`** returns the resolved current node: a cutscene
+  (`componentKey`), a level (`levelSlug`), or a **dialogue tree** (all utterances with
+  resolved speaker/pose, ordered `childIds`, and each exit's `terminalKey`, plus the
+  `rootId`).
+- **`advance(terminalKey?)`** follows a terminal, **auto-skips gates** (the stub
+  det_gate takes its first terminal), instantiates the board when entering a level,
+  and finishes when a followed terminal has no target.
+- **Dialogue is walked on the client** (`DialoguePlayer`): play NPC lines with the
+  typewriter; at a branch (2+ player children) present choice buttons; a chosen child
+  leads to its next line or, if it has a `terminalKey`, calls `advance(terminalKey)`
+  to leave the node — routing the graph to a different next node.
+
+## Glass Harbour seed
+
+Authored in `mysteries/glass-harbor/mystery.json` (`narrative.graph`) and seeded by
+the importer, so it survives re-imports. It is linear:
+
+```
+[cutscene: glass-harbour-diversion] → [dialogue: Briefing] → [level: glass-harbor] → [dialogue: Debrief] → (end)
+```
+
+Branching (player options routing to different terminals) is supported and tested,
+just not used in the seed.
+
+## Implemented vs deferred
+
+**Implemented:** graph schema, node/terminal/utterance CRUD + admin editors, the
+runtime cutover (cutscene / dialogue-tree / level traversal, branching dialogue),
+the vertical mystery-graph canvas, the utterance crafter, and the seed.
+
+**Deferred:**
+- **Real gates.** `det_gate` is a hardcoded "first terminal" stub; `llm_gate` is
+  unbuilt. Both want the **Case Report / Claims** (Milestone 5) as input, plus a
+  gate-function registry keyed like cutscene components.
+- **Within-node loops** (an utterance's single parent makes each dialogue a tree).
+- **Drop `advances_to_utterance_id`** and the reserved `effect` column.
+- **Cutscene params** and real pose art.
+
+## Validation rules
+
+- One `entry_node_id` per mystery (soft-recommended to be a `cutscene`).
+- A terminal's `to_node_id` must share its parent node's mystery (repo-enforced).
+- An utterance's `terminal_id` must belong to its node; parent links stay in-node.
+- Unreachable nodes and unwired terminals are allowed (deliberate ends).

+# Mystery content packages
+
+Mysteries live outside the React application as authoring manifests and immutable source assets. Importing a manifest exercises the same public operations as the level editor: it creates a mutable authoring level, uploads assets, saves normalized exhibits, freezes an immutable template version, and instantiates a separate playable level.
+
+With the local Docker stack running and editing enabled:
+
+```bash
+npm run mystery:import -- mysteries/glass-harbor/mystery.json
+```
+
+The command prints the template version, authoring-level ID, playable-level ID, and player URL. Importing the same manifest again creates a new immutable version; it does not rewrite an earlier version.
+
+## The Glass Harbor Diversion
+
+This compact first mystery contains eight dated source documents in three folders, six unresolved Party concepts, and one fictional archival photograph. It intentionally starts without Party or Event exhibits: classification, dossier association, event reconstruction, working notes, and red-thread theory are the player’s work.
+
+The source image was generated with the built-in image-generation tool for this fictional case. Its final production prompt asked for a degraded 1987 harbor-security photograph of truck `H&F 14` unloading a `CALDER OPTICAL / FRAGILE` crate at Warehouse 3, with period-correct details and no real people or brands.
