-- Phase 5j Slice A: paliad-shape redesign of projax.views.
--
-- 5i (0016) modelled views as overlays on existing pages keyed by uuid.
-- m's feedback: that's the wrong shape — views should be first-class
-- pages at /views/{slug}, mirroring paliad's user_views model.
--
-- This migration HARD-REPLACES the 5i table. m's pick on Q10 (2026-05-29):
-- hard-replace is fine because 5i was hours old with no persisted user
-- data of value. Any rows present get dropped along with the table.
--
-- m's other picks worth marking inline:
-- Q2 (2026-05-29): view_type lives INSIDE filter_json, not as a
-- top-level column with a CHECK constraint. Keeps the
-- schema lean — the renderer parses the JSON anyway.
-- Q9 (2026-05-29): is_default_for column dropped entirely. MRU
-- (last_used_at) replaces the per-page-default model.
-- Q11 (2026-05-29): graph stays outside the views enum; no graph
-- view_type ever lands in filter_json.

# Views redesign — paliad-shape first-class views (Phase 5j)
**Status**: Phase A design (this doc).
**Branch**: `mai/kahn/phase-5j-views-redesign`.
**Author**: kahn (inventor), 2026-05-26.
**Source feedback** (m, 13:19 2026-05-26): *"It's not really what I wanted. It should like the paliad custom views, not of the existing views a variant but individually created views."*
**Replaces**: Phase 5i. Hours-old, no real data, drop-and-rebuild is the cleanest path.
---
## §1 — Diagnosis: why 5i diverged from intent
5i modelled views as an **overlay** on top of existing pages. The contract was:
> User opens `/?view=<uuid>` → the saved filter+view_type fields onto whatever the existing tree handler renders.
That choice flowed from m's original phrasing: "view types (card / list / calendar / kanban)" — which sounded like skin-on-top-of-pages. Implementation followed: TreeFilter grew a `ViewID`, an `applySavedView` overlay landed in the tree handler, the sidebar `Views` entry pointed to `/views` as a list-management page, and saved views had no URL of their own.
m's **actual** mental model, anchored in paliad: a view IS a page. The slug goes in the URL. System defaults (dashboard, calendar, timeline, ...) and user-created views share the same `/views/{slug}` route shape. Nothing is "an overlay" — views are first-class destinations, indexed in the sidebar, with their own editor.
The fix: tear out the 5i overlay code and rebuild around the paliad model. This redesign mirrors paliad's structure but adapts to projax's constraints (single-user, no auth.uid(), no RLS, existing route surface).
---
## §2 — paliad-shape data model for projax
### Schema (migration `0017_views_redesign.sql`)
**Recommendation: hard-replace.** Drop `projax.views` (created hours ago in 5i Slice D), recreate fresh. No real user data lost — at most a couple of throwaway saved-view rows from m's testing.
```sql
DROP TABLE IF EXISTS projax.views CASCADE;
CREATE TABLE projax.views (
id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
slug text NOT NULL,
name text NOT NULL,
icon text, -- nullable; matches frontend icon registry
filter_json jsonb NOT NULL DEFAULT '{}'::jsonb,
view_type text NOT NULL, -- card | list | calendar | kanban | timeline
sort_field text,
sort_dir text,
group_by text,
sort_order integer NOT NULL DEFAULT 0,
show_count boolean NOT NULL DEFAULT false,
last_used_at timestamptz,
created_at timestamptz NOT NULL DEFAULT now(),
updated_at timestamptz NOT NULL DEFAULT now(),
CONSTRAINT views_view_type_chk
CHECK (view_type IN ('card','list','calendar','kanban','timeline')),
CONSTRAINT views_sort_dir_chk
CHECK (sort_dir IS NULL OR sort_dir IN ('asc','desc')),
CONSTRAINT views_kanban_needs_group
CHECK (view_type <> 'kanban' OR group_by IS NOT NULL),
CONSTRAINT views_slug_format_chk
CHECK (slug ~ '^[a-z0-9][a-z0-9-]{0,62}$')
);
CREATE UNIQUE INDEX views_slug_uniq ON projax.views (slug);
CREATE INDEX views_sort_order_idx ON projax.views (sort_order, name);
-- updated_at trigger reused from 0016 (kept under a new name or recreated).
CREATE OR REPLACE FUNCTION projax.views_touch_updated_at()
RETURNS trigger LANGUAGE plpgsql AS $$
BEGIN
NEW.updated_at := now();
RETURN NEW;
END;
$$;
DROP TRIGGER IF EXISTS views_touch_updated_at ON projax.views;
CREATE TRIGGER views_touch_updated_at
BEFORE UPDATE ON projax.views
FOR EACH ROW EXECUTE FUNCTION projax.views_touch_updated_at();
```
### Key shifts from 5i
| field | 5i | 5j | reason |
|---|---|---|---|
| primary key | uuid only | uuid; **slug is the URL key** | paliad parity — URLs use slugs, not uuids |
| slug | absent | required, unique, regex-validated | URL routability |
| icon | absent | nullable text | sidebar icon picker |
| sort_order | absent | server-assigned MAX+1 | drag-reorder; paliad parity |
| show_count | absent | bool, opt-in | sidebar row-count badge; opt-in cost |
| last_used_at | absent | nullable timestamptz | `/views` landing MRU redirect |
| pinned | bool | **dropped** | `sort_order` subsumes the use case |
| is_default_for | text page | **dropped** | per-page-default model gone; MRU replaces it |
### `filter_json` shape
Unchanged from 5i (the JSON shape stayed correct). Keys mirror TreeFilter dims: `q`, `tags[]`, `management[]`, `status[]`, `has_links[]`, `public`, `show_archived`, `project_path`, `include_descendants`. The shape is forward-compatible; new TreeFilter dimensions land without migrations.
`view_type` stays a top-level column (not inside `filter_json`) because the editor + sidebar both read it without needing to parse JSON.
### Single-user simplifications vs paliad
- **No `user_id` column** — projax is Tailscale-only single-user.
- **No RLS** — same reason.
- **`UNIQUE (slug)` is global**, not per-user.
If multi-user ever lands, the column + index gain a `user_id` prefix; the rest of the design holds.
---
## §3 — Reserved slugs (system views)
The big call: **do existing pages become system views, or do they stay distinct routes?**
### Three options
**(a) Keep current routes; add /views/{slug} for user views only.**
- `/`, `/dashboard`, `/calendar`, `/timeline`, `/graph` stay exactly as today.
- `/views/{slug}` is exclusively for user-created views.
- Reserved-slug list is just `{new, edit}` (the literal route segments) + any future top-level URL we'd not want a user view to shadow.
- **Cost**: nothing changes for muscle memory. User views are an additive concept beside existing pages.
- **Drawback**: the conceptual asymmetry m flagged stays — system pages live at `/`/`/dashboard`, user views live at `/views/{slug}`. Two URL families.
**(b) Full migration. Existing pages become system views at `/views/{slug}`.**
- New URLs: `/views/tree`, `/views/dashboard`, `/views/calendar`, `/views/timeline`, `/views/graph` (or drop graph from the unified shape — see §3.1).
- Legacy `/`, `/dashboard`, etc. become 301 redirects to their `/views/{slug}` counterpart.
- Reserved slugs: `{tree, dashboard, calendar, timeline, graph, new, edit, admin, login, logout, healthz, mcp, static, i, views}` — everything projax owns at the top level.
- **Cost**: every internal link in templates needs updating; bookmarks 301 (fine); browser muscle memory absorbs after one shift.
- **Benefit**: one URL family. The "create a new view" mental model is uniform with how system pages live.
**(c) Hybrid. Legacy routes stay; `/views/{slug}` aliases system pages and hosts user views.**
- `/` keeps serving the tree; **also** `/views/tree` resolves to the same handler.
- `/dashboard` keeps; also `/views/dashboard`. Etc.
- Reserved slugs match (b) for the same coverage.
- User views land at `/views/{their-slug}` alongside system slugs in one URL family.
- **Cost**: small — system-view handlers register two route entries instead of one. No redirects to maintain.
- **Benefit**: muscle memory + bookmark stability AND first-class /views/{slug} URL family. Two paths to the same render; user picks whichever they remember. If `/views/{slug}` catches on, a future shift can deprecate the legacy URLs cleanly.
### Inventor pick: (c) hybrid
**Reasoning**: m's bug report explicitly said "individually created views" — the gap was user-view first-classness, not legacy-URL banishment. (c) closes the gap with zero migration cost. (b) is cleaner architecturally but introduces avoidable churn; the upside (one URL family) doesn't outweigh the risk of breaking some link or muscle-memory in m's daily flow. (a) leaves the two-families asymmetry m's feedback was pointing at.
This is **Q1 in §9** — head should ratify or override before coder.
### §3.1 — Graph as a system view?
Graph is the DAG SVG render. It's NOT in the view_type enum (per 5i design, intentionally — graph is its own visualization, not a "list of items rendered as X"). Recommend: keep `/graph` and `/views/graph` (under (c)) but **graph is not a user-creatable view_type** — the create form omits it. Reserved slug `graph` blocks user views from clobbering it.
### Reserved-slug list (combining (c) + projax's existing top-level routes)
```go
var reservedViewSlugs = []string{
// System pages (also reachable via /views/<slug> as aliases under (c)):
"tree", "dashboard", "calendar", "timeline", "graph",
// /views sub-routes:
"new", "edit",
// Top-level application URLs:
"admin", "login", "logout", "healthz", "mcp", "static", "i", "views",
}
```
---
## §4 — Routes
For option (c). Under (b), drop the legacy entries; under (a), drop the `/views/{system-slug}` aliases.
| route | handler | renders | semantics |
|---|---|---|---|
| `GET /views` | `handleViewsLanding` | 302 to MRU view, else onboarding shell | landing |
| `GET /views/{slug}` | `handleViewRender` | view template per view_type | render saved or system view |
| `GET /views/new` | `handleViewEditor` | editor blank | editor — new |
| `GET /views/{slug}/edit` | `handleViewEditor` | editor pre-filled | editor — edit existing |
| `POST /views` | `handleViewCreate` | redirect to `/views/{slug}` | create |
| `POST /views/{slug}` | `handleViewUpdate` | redirect to `/views/{slug}` | update |
| `POST /views/{slug}/delete` | `handleViewDelete` | redirect to `/views` | delete |
| `POST /views/reorder` | `handleViewReorder` | 204 / HTMX OK | drag-reorder (slice G) |
| `POST /views/{slug}/touch` | `handleViewTouch` | 204 fire-and-forget | bump last_used_at on render |
The render path (`GET /views/{slug}`):
1. Resolve slug. If a user view → load row. If a reserved system slug → load the corresponding code-resident `SystemView` struct.
2. Touch `last_used_at` (user views only — system views don't track MRU per call).
3. Dispatch to the view_type's renderer (the same per-view-type templates from 5i: `tree_card.tmpl`, `tree_kanban.tmpl`, `tree_section.tmpl` for list, plus the existing `calendar_section.tmpl` and `timeline_section.tmpl`).
4. Apply chip-overlay semantics from the 5i fix — URL chips overlay the saved filter so chip clicks narrow within the view (the one piece of 5i worth keeping; see §7).
Editor (`GET /views/new` and `GET /views/{slug}/edit`) is a dedicated full-page form, not a modal. Paliad shipped dedicated pages; projax inherits the same shape.
---
## §5 — Sidebar integration
Replace the single "Views" sidebar entry (5i) with a "Views" section listing every user view. System views stay in the existing main-nav block at the top; they're already the muscle-memory entries (Tree, Dashboard, Calendar, Timeline, Graph).
ASCII sketch (5g sidebar shape, with 5j additions):
```
[ sidebar ]
─────────────
⌂ Tree
□ Dashboard
▣ Calendar
⊿ Timeline
⨀ Graph
─────────────
Views ← new section header
📂 Active mai work ← user view (icon + name)
⏰ This week deadlines ← row-count badge if show_count
★ Patents kanban ← drag-reorder handle on hover
+ New view ← /views/new
─────────────
⚙ Admin
─────────────
☾ Theme
```
The Views section's entries come from `ListViews()` ordered by `sort_order` ASC, then `name`. Each entry:
- Icon resolved against a small frontend registry (the icon column is a key; the registry maps it to an SVG). Keys: `folder`, `clock`, `star`, `tag`, `file-text`, `box`, `inbox`, etc. Default key: `folder`.
- Optional badge with row count when `show_count=true` — computed by running the view's filter against `ListAll()` (cheap; projax's scale is ~150 items max).
- Active state when the current URL is `/views/{this-slug}` or a legacy alias resolving to it.
Drag-reorder lands in a later slice (G). Click-to-open is the v1 interaction.
Mobile bottom-nav drawer (5g slice B) gets the same section.
---
## §6 — Editor surface
Single editor template (`templates/view_editor.tmpl`) reused for both `/views/new` and `/views/{slug}/edit`. Distinguishes via the presence of `.View` in the data map.
Fields:
- **Name** — text input, required, max 80 chars.
- **Slug** — text input, regex `^[a-z0-9][a-z0-9-]{0,62}$`, **auto-derived** from name via HTMX on `change` against a `POST /views/derive-slug?name=<x>` helper endpoint OR on the client (simpler: derive on the server side in `handleViewCreate` if the field is empty; provide a "regenerate" link in edit mode). m can hand-edit.
- **Icon** — `<select>` with the registered icon keys + a visible preview. Slice D ships the form field; the registry SVG additions can grow incrementally.
- **View type** — radio group (5 values: card/list/calendar/kanban/timeline).
- **Filter (chip strip)** — full TreeFilter chip strip inline in the editor: tag, mgmt, status, has, public, project picker + descendants toggle. Each chip click updates a hidden `filter_json` field via HTMX — so the editor's preview pane reflects the saved filter live.
- **Sort field** — text input (`title` / `updated_at` / `start_time`).
- **Sort dir** — `<select>` (asc/desc).
- **Group by** — `<select>` (status/area/tag/management). Required when view_type=kanban.
- **Show count** — checkbox.
A small "Preview" pane next to the form shows the first N items the filter currently matches. Optional in slice D; can land in slice G if scope bites.
Save → 302 to `/views/{slug}`. Cancel → `/views` (or the previous URL if HTMX-loaded).
**Drops the HTMX modal** the 5i fix-shift added — dedicated pages are clearer for a page-level concept and match paliad's pattern.
---
## §7 — Migration from 5i overlay
Specific deletions and salvages:
### Code to delete
| file | what to remove |
|---|---|
| `web/tree_filter.go` | `ViewID` field on TreeFilter; `ParseTreeFilter`/`QueryString` handling |
| `web/views.go` | `applySavedView`, `applyDefaultView`, `overlayURLFields`, `filterQueryToJSON`/`filterJSONToQuery`, the `Prefill` index handler logic |
| `web/server.go` | the `?view=<uuid>` overlay block in `handleTree`; the `DefaultBanner` data map field |
| `web/templates/tree_section.tmpl` | the `default-banner` block; the `<input type="hidden" name="view">` |
| `web/templates/views.tmpl` | full rewrite — it's the list-management surface, redesigned in §5 + §6 |
| `web/templates/view_edit.tmpl` | full rewrite to the new editor shape |
### Code to keep
- `templates/tree_card.tmpl`, `templates/tree_kanban.tmpl` — these are per-view_type renderers, reusable.
- `web/view_type.go` (the 5-value enum + `PageViewTypes` catalog) — still valid as the renderer dispatch table.
- `web/kanban.go` (`BuildKanbanBoard`) — view_type=kanban consumer.
- `templates/project_chip.tmpl` — the project filter chip strip works inside the editor.
- The 5i chip-overlay-on-saved-view fix is the **one piece of substance** worth keeping conceptually: on `/views/{slug}`, URL chip params overlay the saved filter. The overlay function gets a new home (`handleViewRender`'s filter-resolution path) but the rule is the same.
### Backwards compatibility for the old `?view=<uuid>` URL
Two options:
- (i) **404 on `?view=`** for existing pages — the URL never makes sense in the new model. Cost: any stale bookmark dies, but only m used it for hours.
- (ii) **302-redirect `/<page>?view=<uuid>` to `/views/<slug>`** by looking up the slug from the uuid. Smoother for m's recent bookmarks. Cost: one extra DB hit on the redirect path; the redirect can target the slug or, if the uuid no longer resolves (because we hard-recreated the table), 302 to `/views`.
Inventor pick: (ii) — small code, no broken bookmarks for the brief 5i window.
### `is_default_for` semantics
Drop entirely. The MRU mechanism (`last_used_at``/views` landing) replaces "what should I see on /views". Per-page defaults are gone; if m wants a specific view to be the landing experience, he opens it once and it becomes MRU.
If m later wants a "this is my default" hint stronger than MRU (i.e., pinning), `sort_order=0` reserved for a pinned slot + an `is_pinned` flag is the natural extension. **Not in scope for v1.**
---
## §8 — Implementation slicing
Seven slices; A → B → C → D → E are the critical path; F + G are polish.
### Slice A — Schema redesign
- Migration `0017_views_redesign.sql`: `DROP TABLE projax.views CASCADE; CREATE TABLE` with new shape. (See §2 schema.)
- `store/views.go`: rewrite. Rename `View.ID` flow to be slug-driven; `GetView(slug)` instead of `GetView(uuid)`. Keep CRUD shape; add `Touch(slug)` for MRU; add `MostRecent()` returning the MRU view (or nil); add `Reorder([]string slugs)` for slice G.
- Drop `DefaultViewFor` (no longer applicable).
- Tests: round-trip CRUD by slug; reserved-slug rejection at the validator; slug-format regex enforcement; MRU.
### Slice B — Route migration (paliad-shape)
- Replace the 5i `/views/<uuid>` routes with the paliad-shape route table from §4.
- `handleViewsLanding` → MRU redirect or onboarding shell.
- `handleViewRender` → resolve slug (user view first, then system view), apply chip overlay, dispatch to the view_type's renderer.
- `handleViewEditor` → dedicated form page (slug-driven).
- `handleViewCreate` / `handleViewUpdate` / `handleViewDelete` → form POST handlers.
- `handleViewTouch` → fire-and-forget MRU update.
- Wire the legacy `?view=<uuid>` redirect (per §7-ii) on existing pages.
- Tests: each route hit, slug routing, MRU redirect, onboarding shell on empty state, reserved-slug rejection.
### Slice C — System views
- New `web/system_views.go` with `SystemView` struct + `TreeSystemView()`, `DashboardSystemView()`, `CalendarSystemView()`, `TimelineSystemView()`, `AllSystemViews()`, `LookupSystemView(slug)`.
- Each function returns the `(filter_json, view_type, group_by, sort)` tuple matching today's page.
- `handleViewRender` falls back to `LookupSystemView` when the slug isn't in the DB.
- Reserved-slug list (combining system slugs + route segments).
- Under (c) hybrid: legacy routes `/`, `/dashboard`, `/calendar`, `/timeline` each gain a sibling registration so `/views/{system-slug}` resolves to the same handler. (Or: legacy routes 302 to `/views/{slug}` — simpler if m's fine with one canonical URL.)
- Tests: system-view lookup, slug aliases hit the same template, reserved-slug rejection during user-view create.
### Slice D — Editor surface
- New `templates/view_editor.tmpl` — full form per §6.
- Slug derivation helper (`POST /views/derive-slug` or server-side fill).
- Icon picker (a `<select>` for v1 — frontend registry expansion is incremental).
- Inline chip strip inside the form; HTMX updates a hidden `filter_json` on every chip click.
- Tests: GET /views/new renders blank form; GET /views/{slug}/edit pre-fills; POST creates/updates round-trip.
### Slice E — Sidebar integration
- `templates/layout.tmpl`: insert a "Views" section between main nav and `/admin`.
- Server-side: every page-render pulls `ListViews()` into the layout data map (cached lightly so each request doesn't hit the DB twice).
- Active-state CSS + icon rendering.
- Mobile drawer (5g slice B) gets the same section.
- Tests: sidebar shows user views; clicking navigates to `/views/{slug}`; active state matches URL.
### Slice F — Migration cleanup (delete 5i overlay)
- Remove TreeFilter.ViewID.
- Remove `applySavedView`, `applyDefaultView`, `overlayURLFields`, the default-view banner.
- Remove the 5i `/views/<id>` redirect handler (slice B replaces it).
- Tests adjusted: drop the `ViewID` round-trip test; drop `TestSavedViewAppliedOnQueryParam`, `TestDefaultViewAppliedOnCleanURL`, `TestViewEditFlow` — their slice-A successors cover the new shapes.
### Slice G — Polish
- Drag-reorder UI via HTMX `hx-post="/views/reorder"` with sortable.js or a tiny vanilla drag-handle (m's HTMX-only constraint allows minimal vendored JS if needed).
- `show_count` badge wiring (run filter against `ListAll()`, render the count next to the sidebar entry).
- Preview pane in the editor (optional).
- Icon registry expansion (curated SVGs).
Slices F and G are independent. The implementation chain is **A → B → C → D → E → (F either before or after E) → G**.

## §9 — Open questions for head delegation
Inventor picks marked. Process: **NO direct chip-picker** without head's explicit grant for this round.
### Q1 — System-view shape (§3)
(a) Keep current routes only; user views beside them at `/views/{slug}` — current asymmetry stays.
(b) Full migration; existing pages become system views, legacy URLs 301-redirect — paliad parity.
(c) Hybrid; both URL families coexist, system slugs aliased — preserves muscle memory.
**Inventor pick**: (c). Closes the asymmetry m flagged, zero migration cost. (b) is cleaner but risks broken bookmarks for thin upside.
### Q2 — `view_type` field placement
- (a) Top-level column (5j inventor pick — matches 5i, query-able without parsing JSON).
- (b) Inside `filter_json`.
**Inventor pick**: (a).
### Q3 — Legacy `?view=<uuid>` URL handling (§7)
- (a) 404 — clean break.
- (b) 302-redirect to `/views/<slug>` by uuid lookup — smoother for m's recent bookmarks. Inventor pick.
**Inventor pick**: (b).
### Q4 — Editor surface (§6)
- (a) Dedicated pages `/views/new` + `/views/{slug}/edit` — paliad parity, inventor pick.
- (b) Keep the HTMX modal from the 5i fix — less navigation but harder to share/bookmark mid-edit.
**Inventor pick**: (a).
### Q5 — `/views` landing MRU redirect
- (a) 302 to MRU saved view if any, else onboarding shell (paliad model, inventor pick).
- (b) Always show the views index list page.
**Inventor pick**: (a).
### Q6 — Icon picker in v1?
- (a) Yes — small select + 8-12 curated keys; rendered inline in the sidebar entries.
- (b) v2 — ship without icons in v1; sidebar uses a generic folder glyph for every entry.
**Inventor pick**: (a) — the schema column lands either way; UI cost for a `<select>` is trivial.
### Q7 — Drag-reorder in v1?
- (a) Yes (slice G in v1).
- (b) v2 — `sort_order` column is server-assigned MAX+1 on create; reorder UI lands later.
**Inventor pick**: (b). Don't expand v1 scope; reorder is a UX polish that can ship a week after.
### Q8 — `show_count` badge in v1?
- (a) Yes — opt-in checkbox in editor + sidebar badge.
- (b) v2 — column lands in the schema; UI lands later.
**Inventor pick**: (a) — checkbox in editor + 2-line render in sidebar is cheap and answers the "how many things match my view" question m asks naturally.
### Q9 — Legacy `is_default_for` semantics (§7)
Inventor picks **dropped entirely**, replaced by MRU. Flag if m wants pin / default semantics back.
### Q10 — Drop and recreate `projax.views`?
- (a) Hard-replace via `DROP TABLE ... CASCADE` — inventor pick (table is hours old, ~zero data loss).
- (b) ALTER TABLE migration that adds new columns + drops old ones gracefully — more conservative; preserves any rows m has created.
**Inventor pick**: (a). The shape change is large enough that a clean re-create is cleaner than a 6-step ALTER.
### Q11 — `view_type=graph`?
The graph DAG SVG render isn't in the view_type enum. Should:
- (a) Stay outside the views system — `/graph` and `/views/graph` (system slug) both serve it, user views can't be `view_type=graph`. Inventor pick.
- (b) Add `graph` as a sixth view_type — opens user-creatable graph views.
**Inventor pick**: (a). Graph layout is single-purpose (DAG); a "graph of my filtered set" doesn't have a clear product story today.

## §10 — Risk register
| risk | likelihood | mitigation |
|---|---|---|
| Slug collision on rename | medium | UNIQUE index + handler maps the unique-violation to a friendly "slug already in use" error |
| URL drift (legacy bookmarks break) | low under (c), high under (b) | (c) keeps legacy URLs; (b) ships with 301 redirects + a session of m verifying his bookmarks |
| MRU thrash on rapid view switches | low | `last_used_at` is fire-and-forget; the worst case is one stale 302 |
| System-view + user-view slug collision | n/a | reserved-list rejection in validator (slice A) |
| sidebar query cost | low | `ListViews()` is one indexed lookup per page render; cache lightly if it shows in profiling |
| Editor's chip strip drifts from the page chip strip | medium | share the same template (project_chip.tmpl already shared); add a dedicated `view_filter_chips.tmpl` if drift bites |

## §11 — Test plan headlines
### Slice A
- `TestViewSlugCRUD` — create/get/update/delete by slug round-trip.
- `TestViewSlugFormatRejected` — uppercase, underscore, leading-digit-allowed but no-leading-dash, length-cap 63.
- `TestViewReservedSlugRejected` — create with slug `tree` / `dashboard` / `admin` / `new` etc. all 400.
- `TestViewTouch` — Touch bumps `last_used_at`.
- `TestViewMostRecent` — MRU returns most recently touched.
### Slice B
- `TestViewsLandingMRU``/views` 302s to MRU view when one exists.
- `TestViewsLandingOnboarding``/views` renders shell when no views.
- `TestViewRender``/views/{slug}` resolves a user view; renders the right view_type template.
- `TestLegacyOverlayRedirect``/?view=<uuid>` 302s to `/views/{slug}`.
### Slice C
- `TestSystemViewLookup``tree` / `dashboard` / `calendar` / `timeline` / `graph` resolve via `LookupSystemView`.
- `TestSystemViewSlugAlias``/views/dashboard` and `/dashboard` produce identical render output.
### Slice D
- `TestEditorBlank``/views/new` renders empty form.
- `TestEditorPrefilled``/views/{slug}/edit` reflects every persisted field.
- `TestSlugDerivation` — name "Active mai work" → slug "active-mai-work".
### Slice E
- `TestSidebarListsViews` — layout includes every user view.
- `TestSidebarActiveState``/views/{slug}` marks that entry active.
### Slice F
- All 5i overlay tests deleted; no residue references TreeFilter.ViewID.
### Slice G
- `TestReorderUpdatesSortOrder` — POST `/views/reorder` with a sorted slug list updates the column.
- `TestShowCountBadge` — sidebar badge reflects the filter's match count.

## §13 — Status
- **Phase A (this doc)**: drafted by kahn, 2026-05-26. Awaiting head delegation of §9 questions to m.
- **No chip-picker for 5j** unless head explicitly re-grants per the project's escalation rule.
- **Phase B (coder)**: blocked on m's sign-off via head. Slice ordering A → B → C → D → E → F → G.
- **No code changes** in this branch beyond this doc.
