It defines the recommended product behavior, data to collect, and likely extension points in the current app.\n\n## Summary\n\nRecommended approach:\n\n- Parents submit project proposals into a separate proposal queue.\n- Admins review proposals with minimal work.\n- Only approved proposals become live projects visible to students.\n- Parents indicate availability, not exact placement.\n- Projects may span multiple consecutive timeslots.\n- A 2-timeslot project means the same children attend both timeslots in order.\n\n## Why Separate Proposals From Live Projects\n\nDo not write parent submissions directly into the live `project_options` table.\n\nReasons:\n\n- Parent submissions will often be incomplete or inconsistent.\n- Admins need to place projects into the timetable based on overall availability.\n- Some projects will need editing before they are suitable for student-facing display.\n- Multi-timeslot projects need scheduling logic before they can be shown to children.\n\nRecommended flow:\n\n1. Parent submits a proposal.\n2. Admin reviews it in a queue.\n3. Admin approves, edits, or rejects it.\n4. Approval creates the actual scheduled project records used by the existing app.\n\n## Parent Submission Data\n\n### Required\n\n- Parent name\n- Email address\n- Project title\n- Short public description\n- Maximum number of children\n- Age suitability\n- Availability across timeslots\n- Project duration in timeslots, default `1`\n\n### Strongly recommended\n\n- Phone number\n- Materials children should bring\n- Indoor / outdoor / either\n- Space or room requirements\n- Materials provided by parent\n- Optional co-facilitator / second adult\n- Notes for admins\n\n### Optional but useful later\n\n- Minimum number of children\n- Setup time needed\n- Cleanup time needed\n- Safety considerations\n- Accessibility notes\n- Whether the project can be repeated for another group\n\n## Proposed Parent-Facing Field Definitions\n\n- `parent_name`: text, required\n- `parent_email`: email, required\n- `parent_phone`: text, optional\n- `project_title`: text, required\n- `project_description`: long text, required\n- `co_facilitators`: text, optional\n- `max_participants`: integer, required\n- `min_participants`: integer, optional\n- `age_group`: enum or multi-select, required\n- `age_group_notes`: text, optional\n- `materials_to_bring`: long text, optional\n- `materials_provided`: long text, optional\n- `location_type`: enum `indoor | outdoor | either`, optional\n- `room_requirements`: long text, optional\n- `availability_timeslot_ids`: list of timeslot ids, required\n- `duration_slots`: integer, required, default `1`\n- `admin_notes_from_parent`: long text, optional\n\n## Age Groups\n\nKeep age groups open-ended.\n\nDo not hardcode only the current school-specific labels yet, because there may be one or two more groups later.\n\nRecommended approach:\n\n- store age groups in configurable data rather than fixed code enums\n- allow multiple selectable age-group options per project if needed\n- preserve an optional free-text note for exceptions or mixed groups\n\nCurrent examples:\n\n- `Delfine` = Klasse 1-3\n- `Drachen` = Klasse 4-6\n- `7/8` = Klasse 7-8\n- `9/10` = Klasse 9-10\n\nPractical consequence:\n\n- the parent form should read age-group options from configurable data\n- the admin review flow should tolerate changes to the age taxonomy without schema rewrites\n\nRecommended configurable structure:\n\n- `id`\n- `label`\n- `min_class`\n- `max_class`\n- `sort_order`\n- `active`\n\nInitial values:\n\n- `delfine`, `Delfine`, `1`, `3`\n- `drachen`, `Drachen`, `4`, `6`\n- `7-8`, `7/8`, `7`, `8`\n- `9-10`, `9/10`, `9`, `10`\n\n## Availability And Scheduling Rules\n\nParents should mark availability only.\n\nAdmins choose the actual scheduled start slot.\n\nRules:\n\n- A proposal can list multiple available timeslots.\n- `duration_slots = 1` means the project occupies one timeslot.\n- `duration_slots = 2` means the project occupies two consecutive timeslots.\n- A 2-slot project is one continuous project for the same children.\n- The second slot is not assigned independently.\n\nValidation rules for duration `2`:\n\n- Only allow approval into a start slot if the next consecutive timeslot exists.\n- Both timeslots must be included in the parent’s availability.\n- Once approved, both slots are reserved together.\n\n## Recommended Data Model\n\nAdd a proposal layer instead of overloading existing tables.\n\n### New table: `project_proposals`\n\nSuggested fields:\n\n- `id`\n- `parent_name`\n- `parent_email`\n- `parent_phone`\n- `project_title`\n- `project_description`\n- `co_facilitators`\n- `max_participants`\n- `min_participants`\n- `age_group`\n- `age_group_notes`\n- `materials_to_bring`\n- `materials_provided`\n- `location_type`\n- `room_requirements`\n- `duration_slots`\n- `admin_notes_from_parent`\n- `review_status`\n- `admin_review_notes`\n- `approved_start_timeslot_id`\n- `created_at`\n- `updated_at`\n\nRecommended `review_status` values:\n\n- `pending`\n- `approved`\n- `rejected`\n- `archived`\n\n### New table: `project_proposal_availability`\n\nSuggested fields:\n\n- `id`\n- `proposal_id`\n- `timeslot_id`\n\nThis normalizes availability rather than storing it as text or JSON.\n\n## How Approved Proposals Become Live Projects\n\nApproval should create scheduled projects in the existing live project model.\n\n### Short-term compatibility approach\n\nKeep the current student and assignment system mostly intact:\n\n- On approval of a 1-slot proposal, create one record in `project_options`.\n- On approval of a 2-slot proposal, create one record per occupied timeslot in `project_options`.\n- Mark those created records as linked to the same underlying proposal.\n\nFor that, add a lightweight linking field to `project_options`, for example:\n\n- `proposal_id`\n- `project_group_id` or `multi_slot_group_id`\n- `slot_index_within_group`\n\nThis keeps backward compatibility while giving the app enough information to treat multi-slot projects as one offering.\n\n### Longer-term cleaner approach\n\nIntroduce a first-class scheduled project entity:\n\n- one scheduled project\n- many occupied timeslots\n- many linked live choices\n\nThis is cleaner, but not required for a first iteration.\n\n## Student Ranking Behavior\n\nThis needs explicit product behavior before implementation.\n\nRecommended behavior:\n\n- A multi-slot project should be shown once, at its start slot.\n- The UI must clearly indicate that it occupies the next slot too.\n- If a child ranks that project, the following slot becomes unavailable for a separate project.\n\nImplication:\n\n- The current response model is timeslot-centric, so multi-slot choices will require either:\n - special submission logic in the student form, or\n - a translation layer that writes linked responses consistently\n\n## Assignment Behavior\n\nFor approved 2-slot projects:\n\n- Assignment must happen as one block.\n- A child assigned to the project in slot 1 is automatically assigned in slot 2.\n- Capacity applies to the full 2-slot block, not independently per slot.\n- Manual reassignment tools must preserve that linkage.\n\nThis is the part most likely to require actual changes to the current assignment UI and persistence.\n\n## Admin Review Workflow\n\nThe review UI should be intentionally small.\n\nRecommended actions on each proposal:\n\n- `Approve`\n- `Edit and approve`\n- `Reject`\n- `Archive`\n\nRecommended review screen columns:\n\n- Parent name\n- Project title\n- Duration\n- Max participants\n- Age group\n- Availability summary\n- Status\n- Quick actions\n\nRecommended approval flow:\n\n1. Admin opens proposal.\n2. Admin chooses a start timeslot from valid available options.\n3. Admin optionally edits display text.\n4. Admin approves.\n5. System creates live project records and links them back to the proposal.\n\n## Minimal Viable Version\n\nPhase 1 should aim for low complexity:\n\n- Parent proposal form\n- Proposal storage\n- Admin review queue\n- Approve into a scheduled live project\n- Support for duration `1` and `2`\n- No parent editing after submission\n- No draft saving\n- No automatic email notifications\n\n## Suggested Phased Rollout\n\n### Phase 1\n\n- Add proposal intake\n- Add review queue\n- Add approval into existing live project structure\n- Support duration `1` and `2`\n\n### Phase 2\n\n- Improve multi-slot student ranking UX\n- Make assignment UI block-aware for linked timeslots\n- Add validation around consecutive-slot occupancy\n\n### Phase 3\n\n- Parent edits after submission\n- Email confirmation\n- Duplicate/repeat project support\n- Better scheduling assistance for admins\n\n## Google Form Alternative\n\nGoogle Forms is viable for intake, but it is weaker as the long-term solution.\n\n### Pros\n\n- Very fast to set up\n- Familiar to parents\n- No implementation needed for the first collection round\n\n### Cons\n\n- Harder to validate structured constraints like multi-slot availability\n- Harder to keep age groups and timeslots in sync with the app\n- Review and approval become manual copy/paste work\n- Multi-slot project logic will live outside the app\n- Changes to available timeslots require form maintenance in two places\n\n### Recommendation\n\nIf you need something immediately for a one-off round, Google Forms is acceptable.\n\nIf you expect this to become part of the regular Projektwoche workflow, build it into the app. The admin review requirement and the need for multi-timeslot scheduling both argue strongly for native support.\n\n## Open Questions\n\n- What is the final label for the age group above `Drachen`?\n- Should one project ever be repeatable with different children in multiple separate slot blocks?\n- Do you want a hard cap on duration at `2`, or should the model allow more later?\n- Should parents see a confirmation summary after submission?\n- Should admin approval create live projects immediately, or leave them inactive by default until published?\n\n## Recommendation\n\nBuild this into the app rather than relying on Google Forms, unless you need a stopgap this week.\n\nThe simplest robust design is:\n\n- separate proposal queue\n- admin approval\n- parent availability, not parent slot choice\n- explicit duration field\n- linked handling for 2-slot projects\n",[252],"f7cfd16a-5d88-11f1-b3b4-1607ee4eb77e","AGENTS.md","019e8205-0429-72dd-a700-81c0b5556f8d",["D",1780297827276],"# AGENTS\n\n## Project Inventory\n\nThis repository is a Val Town app for managing a school \"Projektwoche\" workflow.\n\nIt has two main user roles:\n\n- Students submit ranked project preferences for each timeslot.\n- Admins manage timeslots and parent-offered projects, inspect submissions, and assign students to projects.\n\nThe live backend is implemented in [backend/index.ts](/Users/chris/fnifs/Projektwoche/backend/index.ts). It uses:\n\n- `Hono` for routing\n- Val Town `sqlite` for persistence\n- `readFile(..., import.meta.url)` to serve static HTML pages from the repo\n\nThere is no separate frontend build step in this repo. The UI is plain HTML/CSS/JS files served directly by the backend.\n\n## Runtime And Hosting\n\n- Host platform: Val Town\n- Local Val Town metadata: [.vt/state.json](/Users/chris/fnifs/Projektwoche/.vt/state.json)\n- Primary backend entrypoint: [backend/index.ts](/Users/chris/fnifs/Projektwoche/backend/index.ts)\n- [main.ts](/Users/chris/fnifs/Projektwoche/main.ts) is currently empty and appears unused\n\nIf you change routes or the HTML filenames, update `readFile(...)` calls and route handlers in `backend/index.ts` together.\n\n## What The App Does\n\n### Domain model\n\n- A \"Projektwoche\" consists of multiple timeslots.\n- Projects are offered by parents; this is represented in the backend via the `offered_by` field on projects.\n- Some projects may span two timeslots. In practice, the app supports this by duplicating or copying a project into multiple timeslots rather than by storing a dedicated multi-slot project entity.\n- Children rank their preferred projects within each timeslot.\n- Admins then assign children to projects, aiming to satisfy the highest-ranked preferences where capacity and constraints allow.\n\n### Student flow\n\n- `GET /` serves [schueler.html](/Users/chris/fnifs/Projektwoche/schueler.html)\n- The page loads active timeslots and their active projects from `GET /api/timeslots`\n- Students submit ranked preferences to `POST /api/responses`\n- Each submission stores one response row per timeslot, linked by a shared `submission_id`\n\n### Admin flow\n\n- `GET /admin` serves [admin.html](/Users/chris/fnifs/Projektwoche/admin.html)\n- Admins can create, edit, activate/deactivate, copy, and delete timeslots and projects\n- Admins can inspect raw response data and export CSV\n- Admins can compute and manually adjust assignments, then save them per timeslot\n- The project-copy workflow is the current mechanism for representing projects that run across more than one timeslot\n\n### Assignment flow\n\nAssignments are a second-stage workflow after students submit preferences:\n\n- [admin-assignments.html](/Users/chris/fnifs/Projektwoche/admin-assignments.html) optimizes assignments for a selected timeslot and allows drag/drop manual correction\n- Saved assignments are stored in the `project_assignments` table\n- [admin-assignments-individual.html](/Users/chris/fnifs/Projektwoche/admin-assignments-individual.html) shows each student’s schedule across timeslots\n- [admin-assignments-by-project.html](/Users/chris/fnifs/Projektwoche/admin-assignments-by-project.html) shows rosters grouped by project\n- The optimizer tries to place children into preferred projects first, but final assignments can be adjusted manually by admins\n\n## File Inventory\n\n- [backend/index.ts](/Users/chris/fnifs/Projektwoche/backend/index.ts): server routes, DB schema, migrations, CSV export, static page serving\n- [schueler.html](/Users/chris/fnifs/Projektwoche/schueler.html): student submission interface\n- [admin.html](/Users/chris/fnifs/Projektwoche/admin.html): admin CRUD page for timeslots and projects\n- [admin-responses.html](/Users/chris/fnifs/Projektwoche/admin-responses.html): grouped submission review and deletion UI\n- [admin-assignments.html](/Users/chris/fnifs/Projektwoche/admin-assignments.html): assignment optimizer and manual adjustment UI\n- [admin-assignments-individual.html](/Users/chris/fnifs/Projektwoche/admin-assignments-individual.html): per-student assignment view\n- [admin-assignments-by-project.html](/Users/chris/fnifs/Projektwoche/admin-assignments-by-project.html): per-project assignment view\n- [assignment.html](/Users/chris/fnifs/Projektwoche/assignment.html): standalone assignment optimizer prototype/tool; it is not served by `backend/index.ts`\n- [README.md](/Users/chris/fnifs/Projektwoche/README.md): partially outdated overview\n\n## API Inventory\n\n### Public routes\n\n- `GET /`\n- `GET /api/timeslots`\n- `POST /api/responses`\n\n### Admin pages\n\n- `GET /admin`\n- `GET /admin/responses`\n- `GET /admin/assignments`\n- `GET /admin/assignments/individual`\n- `GET /admin/assignments/by-project`\n\n### Admin data routes\n\n- `GET /api/debug/data`\n- `GET /api/debug/reset`\n- `POST /api/admin/timeslots`\n- `POST /api/admin/projects`\n- `POST /api/admin/projects/:id/copy`\n- `PUT /api/admin/timeslots/:id`\n- `PUT /api/admin/projects/:id`\n- `DELETE /api/admin/timeslots/:id`\n- `DELETE /api/admin/projects/:id`\n- `DELETE /api/admin/responses/student/:studentName`\n- `DELETE /api/admin/responses/submission/:submissionId`\n- `GET /api/admin/export-csv`\n\n### Assignment routes\n\n- `POST /api/admin/assignments/:timeslotId/save`\n- `POST /api/admin/assignments/:timeslotId/assign`\n- `GET /api/admin/assignments/:timeslotId/load`\n- `DELETE /api/admin/assignments/:timeslotId`\n\n## Database Inventory\n\nTables created in `initDatabase()`:\n\n- `project_timeslots`\n- `project_options`\n- `student_responses`\n- `project_assignments`\n\nImportant schema details:\n\n- `project_options` includes migrated columns `offered_by` and `what_to_bring`\n- `student_responses` stores `submission_id`, so one student submission spans multiple rows\n- `project_assignments` has a uniqueness constraint on `(timeslot_id, student_name)`\n\n## Important Behaviors And Gotchas\n\n- The README no longer reflects the full system. Assignments, `offered_by`, `what_to_bring`, and submission deletion are implemented in code but not fully documented there.\n- There is no auth. All admin pages and admin APIs are publicly reachable if the Val is public.\n- `GET /api/debug/reset` drops tables and reseeds defaults. Treat it as destructive.\n- `GET /api/debug/data` exposes the full data model and is used heavily by the admin pages.\n- The root page injects `window.DYNAMIC_DATA_ENDPOINT` and `window.SUBMIT_ENDPOINT` into `schueler.html` at request time.\n- Default seed data is placeholder content for three Tuesday timeslots and projects A-H.\n- `assignment.html` duplicates assignment logic but is currently separate from the served admin workflow.\n- Two-timeslot projects are currently modeled operationally by copying the same project into multiple timeslots, which means there is no built-in guarantee that those linked entries stay synchronized.\n\n## Editing Guidance\n\nWhen changing this project:\n\n- Keep backend route names and frontend `fetch(...)` calls aligned.\n- Preserve the JSON shapes expected by the HTML pages before refactoring API responses.\n- If you change database columns, update:\n - table creation in `initDatabase()`\n - migration checks in `initDatabase()`\n - CRUD SQL\n - any affected admin or student HTML pages\n- If you introduce first-class support for multi-timeslot projects, review both the submission model and assignment persistence carefully; the current schema is timeslot-centric.\n- If you change how student submissions work, account for the `submission_id` grouping logic used in the admin response pages.\n- If you change assignment persistence, update all three assignment-related HTML pages, not just `admin-assignments.html`.\n\n## Recommended Next Cleanup\n\n- Update [README.md](/Users/chris/fnifs/Projektwoche/README.md) to match the actual current feature set\n- Add auth if this app is intended for real use on a public Val\n- Remove or explicitly document whether

If you need to build on top of it to correct\n earlier mistakes, a new topic branch is created by forking at\n the tip of the \"master\". This is not strictly necessary, but\n it makes it easier to keep your history simple.\n\n * Whenever you need to test or publish your changes to topic\n branches, merge them into \"next\" branch.\n\nThe script, being an example, hardcodes the publish branch name\nto be \"next\", but it is trivial to make it configurable via\n$GIT_DIR/config mechanism.\n\nWith this workflow, you would want to know:\n\n(1) ... if a topic branch has ever been merged to \"next\". Young\n topic branches can have stupid mistakes you would rather\n clean up before publishing, and things that have not been\n merged into other branches can be easily rebased without\n affecting other people. But once it is published, you would\n not want to rewind it.\n\n(2) ... if a topic branch has been fully merged to \"master\".\n Then you can delete it. More importantly, you should not\n build on top of it -- other people may already want to\n change things related to the topic as patches against your\n \"master\", so if you need further changes, it is better to\n fork the topic (perhaps with the same name) afresh from the\n tip of \"master\".\n\nLet's look at this example:\n\n\t\t o---o---o---o---o---o---o---o---o---o \"next\"\n\t\t / / / /\n\t\t / a---a---b A / /\n\t\t/ / / /\n\t / / c---c---c---c B /\n\t / / / \\ /\n\t / / / b---b C \\ /\n\t / / / / \\ /\n ---o---o---o---o---o---o---o---o---o---o---o \"master\"\n\n\nA, B and C are topic branches.\n\n * A has one fix since it was merged up to \"next\".\n\n * B has finished. It has been fully merged up to \"master\" and \"next\",\n and is ready to be deleted.\n\n * C has not merged to \"next\" at all.\n\nWe would want to allow C to be rebased, refuse A, and encourage\nB to be deleted.\n\nTo compute (1):\n\n\tgit rev-list ^master ^topic next\n\tgit rev-list ^master next\n\n\tif these match, topic has not merged in next at all.\n\nTo compute (2):\n\n\tgit rev-list master..topic\n\n\tif this is empty, it is fully merged to \"master\".\n\nDOC_END\n",[],[286,780,810],"f77900ce-5d88-11f1-b3b4-1607ee4eb77e","pre-push.sample","019e8205-0428-7440-918e-1277cfebf8e2",["D",1780297827276],"#!/bin/sh\n\n# An example hook script to verify what is about to be pushed.
