# SLICE 9 — Include opted-in note cards in kanban and matrix views

> **State-saving rule:** update this file and `TASKS.md` after every completed
> task and whenever work pauses. Automated checks and manual Joplin acceptance
> must be recorded separately.

## Status

**COMPLETE.** Phases 1–7 are complete. Automated validation, production packaging, and manual Joplin acceptance all passed.

## Goal

Allow ordinary Joplin notes (`is_todo: 0`) containing a `gtd` fenced block to
appear as cards in kanban and matrix views. Preserve existing to-do behavior and
continue excluding normal notes that have not explicitly opted in.

## Confirmed behavior

- A normal note is eligible only when `extractGtdBlock` reports `found: true`.
- An empty `gtd` block is a valid opt-in, matching existing calendar semantics.
- A malformed `gtd` block still opts the note in and surfaces the existing
  warning; fallback card properties come from the source note.
- The existing `todos:` option continues to govern only to-dos. It does not
  disable or broaden normal-note inclusion.
- No new `notes:` option is introduced in this slice.
- Kanban placement for normal notes:
  - configured in-progress tag -> In Progress;
  - otherwise -> Backlog;
  - never -> Done.
- Matrix placement for normal notes:
  - Eisenhower mode uses the existing important and urgent tags;
  - Skeleton mode uses the existing in-progress tag plus urgent tag/date rules.
- A note date comes only from the `gtd` block. To-do date resolution remains
  block date first, then `todo_due`.
- Note cards reuse block title, colours, icon, and text; missing values fall back
  exactly as existing cards do.
- Normal notes are never completed and never show the recurring-to-do marker,
  even if they happen to carry the configured recurrence tag.
- The host kanban/matrix note remains excluded from its own results.
- SLICE8 batching counts note and to-do cards together after final sorting.

## Inclusion decision table

| Item | `gtd` block | `todos:` | Kanban | Matrix |
|---|---:|---|---|---|
| Normal note | absent | any | excluded | excluded |
| Normal note | present/empty/malformed | any | included | included |
| To-do | absent | `gtd-only` | excluded | excluded |
| To-do | absent | `all` | included | included if incomplete |
| To-do | present | `gtd-only` or `all` | included | included if incomplete |
| To-do | any | `none` | excluded | excluded |
| Completed to-do | any included mode | any | Done-window rules | excluded |

## Architecture and data flow

```text
scoped RawNote
     |
     +-- host note? ------------------------------> exclude
     |
     +-- ordinary note
     |      extract gtd block
     |      absent -> exclude
     |      found  -> build note card -> tags -> bucket
     |
     +-- to-do
            existing todos/completion rules
            -> extract block -> tags -> build card -> bucket

combined bucket -> existing sort -> SLICE8 incremental rendering
```

Collection remains responsible for eligibility, card normalization, tags,
bucketing, sorting, warnings, and totals. The webview should not need separate
rendering logic for note cards.

## Implementation plan

### Phase 1 — Card model and shared builder

- [x] Add an explicit card discriminator to `KanbanCard` in `src/Gtd/types.ts`,
      preferably `isTodo: boolean`, so completion/recurrence rendering does not
      infer item kind indirectly.
- [x] Extract duplicated kanban/matrix card construction into a small shared
      helper only if doing so reduces real duplication without changing public
      collector contracts.
- [x] For normal notes set:
  - `isTodo: false`;
  - `completed: false` and `completedTime: 0`;
  - `isRecurring: false`;
  - date via `resolveEventDate(note, block)`, which correctly ignores `todo_due`
    for normal notes.
- [x] For to-dos preserve current completion and recurrence behavior and set
      `isTodo: true`.
- [x] Update `renderCard` only as needed to choose a neutral note glyph when a
      normal note has no custom icon; retain current checkbox glyphs for to-dos.
- [x] Decide and document the neutral fallback glyph during implementation using
      an existing project-compatible symbol; do not alter custom icons.

### Phase 1 completion record

- Added `isTodo` to the shared card model and centralized kanban/matrix card
  normalization in `buildKanbanCard`.
- Normal-note cards are forced incomplete and non-recurring; to-do completion,
  recurrence, due-date, styling, and override behavior remain unchanged.
- The neutral fallback is `📄`, matching the existing calendar note glyph.
  Custom icons still take precedence, and absent `isTodo` values retain the
  legacy checkbox fallback for compatibility.
- Focused validation: 3 suites and 63 tests passed.
- Full validation: 13 suites and 168 tests passed.
- TypeScript validation and webview JavaScript syntax checks passed.
- No manual Joplin test is required for Phase 1 because normal-note collection
  is not enabled until later phases.

### Phase 2 — Kanban eligibility and bucketing

- [x] Refactor the `collectKanban.ts` loop so host exclusion occurs first, then
      item-kind-specific eligibility.
- [x] For to-dos, preserve `todos: none`, `gtd-only`, and `all` behavior exactly.
- [x] For normal notes, call `extractGtdBlock` and exclude only when no block is
      found.
- [x] Surface malformed-block warnings for included notes with the existing
      message format.
- [x] Fetch tags only after an item is eligible.
- [x] Bucket completed to-dos into Done using the existing done-window cutoff.
- [x] Bucket incomplete to-dos and normal notes by the configured in-progress
      tag; untagged eligible notes go to Backlog.
- [x] Sort the combined note/to-do arrays with the existing configured sorter.

### Phase 2 completion record

- Kanban eligibility now branches by item kind after host-note exclusion.
- Ordinary notes require a found `gtd` block; to-dos retain the existing
  `none`, `gtd-only`, and `all` rules.
- Eligible note cards use existing warning, tag, bucketing, sorting, styling,
  count, and navigation paths. They can enter Backlog or In Progress, never Done.
- Tag lookup occurs only after eligibility is established.
- Focused validation: 2 suites and 38 tests passed.
- Full validation: 13 suites and 174 tests passed.
- TypeScript, whitespace, and prohibited-reference checks passed.
- Phase 4 still must request bodies in `todos: none` mode before opted-in notes
  work with that setting against the Joplin data adapter.
- No manual Joplin test is required yet; mixed-view acceptance remains Phase 7.

### Phase 3 — Matrix eligibility and bucketing

- [x] Apply the same host, item-kind, and shortcode eligibility split in
      `collectMatrix.ts`.
- [x] Preserve completed-to-do exclusion.
- [x] Allow eligible normal notes through because they have no completion state.
- [x] Fetch tags only after eligibility is established.
- [x] Reuse the current Eisenhower tag axes without note-specific exceptions.
- [x] Reuse the current Skeleton active/due-soon rules; dateless normal notes
      naturally fall into the not-due-soon column unless marked urgent.
- [x] Sort combined note/to-do quadrant arrays with the existing sorter.

### Phase 3 completion record

- Matrix eligibility now branches by item kind after host-note exclusion.
- Completed to-dos remain excluded; ordinary notes require a found `gtd` block
  and are not excluded by to-do completion fields.
- Eligible notes reuse the existing Eisenhower and Skeleton axes, sorting,
  warnings, tags, styling, totals, and navigation paths.
- `todos: none` continues to exclude only to-dos at the collector level.
- Tag lookup occurs only after eligibility is established.
- Focused validation: 2 suites and 37 tests passed.
- Full validation: 13 suites and 176 tests passed.
- TypeScript, webview syntax, whitespace, and prohibited-reference checks passed.
- Phase 4 still must request bodies in `todos: none` mode for the real Joplin
  adapter; the collector contract itself is covered.
- No manual Joplin test is required yet; mixed-view acceptance remains Phase 7.

### Phase 4 — Body-fetch contract

Normal-note eligibility can be known only by reading the body. Consequently,
kanban and matrix collectors must request bodies for every scanned folder even
when `todos: none`. The previous `needsBody = config.todos !== "none"`
optimization is no longer valid for these two views.

- [x] Set `includeBody: true` for kanban and matrix folder-note fetches.
- [x] Update collector comments so they no longer claim `todos: none` guarantees
      an empty board.
- [x] Update `src/tests/Gtd/fieldsHint.test.ts` to expect body fetches in all
      kanban/matrix modes.
- [x] Leave calendar and Gantt body-fetch behavior unchanged.
- [x] Document this intentional performance tradeoff in SPEC.md: explicit note
      opt-in requires body inspection, but tag requests remain limited to
      eligible items.

### Phase 4 completion record

- Kanban and matrix now request bodies for every in-scope note, including under
  `todos: none`, so ordinary-note `gtd` opt-in can always be evaluated.
- Calendar body-fetch behavior remains unchanged; Gantt code was not modified.
- Tag requests remain deferred until an item passes eligibility.
- `fieldsHint.test.ts` now records the new board contract in all to-do modes.
- SPEC.md documents the intentional performance tradeoff.
- Focused validation: 3 suites and 76 tests passed.
- Full validation: 13 suites and 176 tests passed.
- TypeScript, webview syntax, whitespace, and prohibited-reference checks passed.
- No manual Joplin test is required for this data-fetch contract; mixed-view
  acceptance remains Phase 7.

### Phase 5 — Automated tests

#### Kanban

- [x] Include a normal note with a valid block.
- [x] Include a normal note with an empty block.
- [x] Include a malformed-block note and retain its warning.
- [x] Exclude a normal note without a block.
- [x] Exclude the host note even when it has a block.
- [x] Place tagged notes in In Progress and untagged notes in Backlog.
- [x] Prove normal notes never enter Done and never become recurring.
- [x] Preserve all `todos:` modes and done-window behavior.
- [x] Verify mixed sorting for due date, title, and modified date.

#### Matrix

- [x] Cover all four Eisenhower quadrants with normal notes.
- [x] Cover Skeleton active/inactive and due-soon/not-due-soon combinations.
- [x] Cover dateless and explicitly urgent normal notes.
- [x] Include empty and malformed blocks; exclude absent blocks and the host.
- [x] Preserve completed-to-do exclusion and all `todos:` modes.
- [x] Verify mixed sorting for due date, title, and modified date.

#### Shared/integration contracts

- [x] Update existing `KanbanCard` fixtures for the item discriminator.
- [x] Verify tags are not requested for ineligible plain notes or excluded to-dos.
- [x] Verify `cardCount` includes all eligible note and to-do cards once.
- [x] Verify SLICE8 works on the combined ordered arrays without renderer changes.
- [x] Run focused kanban, matrix, and fields-hint suites.
- [x] Run the complete Jest suite and record suite/test totals.
- [x] Run `npm run dist` and record the produced `.jpl` path.
- [x] Run `git diff --check` and the prohibited-reference audit.

### Phase 5 completion record

- Added comprehensive mixed note/to-do coverage for valid, empty, malformed,
  absent, and host-note blocks.
- Covered kanban placement, both matrix modes, all to-do modes, completion and
  recurrence invariants, source IDs, warnings, and exact card totals.
- Verified mixed due-date, title, and modified-date sorting.
- Verified `page-size: 1` does not truncate complete collector arrays or totals;
  existing SLICE8 rendering consumes those combined arrays unchanged.
- Focused validation: 4 suites and 89 tests passed.
- Full validation: 13 suites and 185 tests passed.
- TypeScript validation passed.
- Production build passed: `publish/com.victorwiebe.joplin.plugin.gtd-calendar.jpl`
  (155 KB; SHA-256
  `7257bb2bdbb8340539cdad3f88a2ac5f8b55bfa960816f16e472e047311db1cc`).
- `git diff --check` and the prohibited-reference audit passed.
- No manual Joplin acceptance was performed; that remains Phase 7.

### Phase 6 — Documentation

- [x] Update README.md kanban and matrix sections with a normal-note example.
- [x] State clearly that normal notes require a `gtd` block and that `todos:`
      controls only to-dos.
- [x] Document kanban placement, both matrix placement modes, note date rules,
      malformed/empty block behavior, and fallback glyph behavior.
- [x] Update SPEC.md inclusion tables, collection flow, card model, and body-fetch
      tradeoff.
- [x] Add an unreleased SLICE9 entry to CHANGELOG.md without changing the package
      version until release scope is decided.

### Phase 6 completion record

- README.md now documents ordinary-note opt-in, kanban placement, both matrix
  modes, note dates, `todos:` isolation, empty/malformed blocks, fallback
  glyphs, custom icons, and clickable source-note behavior.
- SPEC.md now records the inclusion table, shared card model, collection flow,
  rendering rules, body-fetch tradeoff, and completed unreleased feature.
- CHANGELOG.md includes the unreleased SLICE9 feature and validation results
  without changing the package version.
- The strict prohibited-reference and contradictory-wording audits passed.

### Phase 7 — Manual Joplin acceptance

Use mixed views containing ordinary notes, incomplete to-dos, completed to-dos,
empty blocks, malformed blocks, and plain notes.

**Acceptance package:** `publish/com.victorwiebe.joplin.plugin.gtd-calendar.jpl`
(SHA-256
`7257bb2bdbb8340539cdad3f88a2ac5f8b55bfa960816f16e472e047311db1cc`).

**Accepted:** the user reported all manual checks passed on 2026-07-27.

- [x] Confirm only opted-in normal notes appear.
- [x] Confirm empty blocks opt in and malformed blocks warn without disappearing.

- [x] Record user sign-off here; do not mark manual acceptance complete before
      confirmation.

## Acceptance criteria

SLICE9 is complete only when:

- Every normal note with a found `gtd` block appears exactly once in its expected
  bucket, while every plain normal note remains excluded.
- Existing to-do inclusion, completion, recurrence, done-window, and matrix rules
  remain unchanged.
- Note styling, dates, navigation, warnings, totals, and sorting are correct.
- Mixed arrays obey SLICE8 batching without special renderer branches.
- Focused tests, the full suite, and the production package build pass.
- Manual Joplin acceptance is explicitly confirmed.

## Files expected to change

- `src/Gtd/types.ts`
- `src/Gtd/collectKanban.ts`
- `src/Gtd/collectMatrix.ts`
- Optional shared card-builder module if justified by implementation
- `src/gtd-calendar-webview.js`
- `src/tests/Gtd/kanban.test.ts`
- `src/tests/Gtd/matrix.test.ts`
- `src/tests/Gtd/fieldsHint.test.ts`
- `README.md`
- `SPEC.md`
- `CHANGELOG.md`
- `SLICE9.md`
- `TASKS.md`

## Out of scope

- Including normal notes that lack a `gtd` block.
- Adding a general `notes: all` or `notes: none` option.
- Giving normal notes a completion workflow.
- Editing notes or tags from a kanban/matrix card.
- Changing calendar or Gantt inclusion behavior.
- Child-notebook grouping from SLICE10.

## Dependency and resume point

Implement after SLICE8. Start with collector tests and the explicit card-kind
model, then change eligibility/body fetching. Finish automated regression checks
before documentation and manual acceptance.
