Poem

I mapped twelve moons with careful paws,
Drew dates in rows and tidy laws.
With z-index stacks and Svix at gate,
I drag, I drop, I annotate.
Convex whispers, “Auth is clear!”
Hop—toolbar pops, the path is near. 🐇

convex/utils/encryption.ts (1)

1-170: Update stale encryption imports to the new API

We still have imports pointing to the old path in these files; they need to be updated to pull from convex/utils/encryption (or your project’s canonical alias):

• app/api/auth/google/route.ts
• app/api/auth/google/callback/route.ts
• app/api/auth/caldav/apple/route.ts
• app/api/auth/microsoft/callback/route.ts
• app/api/auth/caldav/generic/route.ts

No legacy calls to decryptToken(a, b, c) remain, and no hard-coded token literals were found. Once the imports are updated, the code will consistently use the new encryptToken/decryptToken signatures.

docs/COMPONENTS.md (1)

110-136: EventModal API in docs does not match code usage; align prop names

Docs show isOpen/onClose/onSave/editingEvent, but the code uses open/onOpenChange/onSave/onDelete/event, selectedDate, selectedRange, checkOverlaps (see LinearCalendarVertical lines 565-574). Update the interface and usage example to match the live API to prevent integration errors.

If the Horizontal foundation exposes a different EventModal API, document both explicitly or standardize on one.

I can PR a corrected EventModal section derived from the component’s actual TypeScript props.

README.md (1)

114-117: Consolidate and de-duplicate testing commands; standardize on pnpm.

The section mixes npm and pnpm and repeats foundation tests (direct Playwright call and script). Use one package manager and a single entry point for consistency.

Apply this diff:

-# Test foundation compliance (MANDATORY before commits)
-npm run test:foundation
-npx playwright test tests/foundation-protection.spec.ts

.taskmaster/tasks/tasks.json (3)

554-556: Status vocabulary is inconsistent with the declared types; align or broaden the schema.

I see statuses like "deferred" and "pending" here, while the new TypeScript definitions only allow 'todo' | 'in-progress' | 'done' | 'cancelled'. This mismatch will break type safety for downstream consumers that rely on the .d.ts. Either:

• normalize JSON to the allowed set, or
• expand the union in .taskmaster/types/task-analytics.d.ts to include 'pending' and 'deferred' (recommended given the breadth of existing data).

Also applies to: 1167-1168, 624-625, 693-694

---

14-22: Subtasks often lack parentTaskId while the type currently requires it.

Examples here show subtasks without parentTaskId; elsewhere it’s present. Either make parentTaskId optional in the type or backfill it consistently for all subtasks in this JSON.

Also applies to: 768-771, 779-782, 791-794

---

1203-1206: Unify Dependency ID Formats in .taskmaster/tasks/tasks.json

The dependencies arrays currently mix plain numeric IDs with string-encoded composite IDs (e.g. "18.1", "19.2"), which violates the number[] schema and will break type-checking and downstream consumers.

Affected locations (examples):

• Task 17 subtasks (Render Queue Manager):
  – subtasks 2–11 include "18.1", "18.2", …, "18.8"
• Task 18 subtasks (Dexie migrations):
  – subtasks 1–9 include "19.1", "19.2", …, "19.8"
• Task 19 subtasks (IntervalTree & layout):
  – subtasks 2–11 include "20.1", …, "20.7"
• Task 21 subtasks (CSP solver):
  – dependencies "22.1", …, "22.6"
• Task 25 subtasks (ARIA Grid):
  – dependencies "26.1", …, "26.10"
• Task 27 subtasks (Full-year viewport feature):
  – dependencies "28.1", "28.2", "28.3", "28.4"
• Task 30 subtasks (HybridCalendar feature):
  – dependencies "31.1", "31.2", "31.4"
• Task 50 subtasks (Test Reliability):
  – dependencies "51.1", "51.2", "51.3", "51.4"
• …and several other subtasks throughout the file.

Refactor Options (pick one):

• Stick with number[]
  • Convert composite references to pure numeric IDs (e.g. split out subtask references into a new field like subtaskDependencies: string[]), or flatten them into integers if the subtask numbering scheme allows.
• Switch to string[]
  • Update the schema to accept string[], document the composite-ID format (e.g. /^\d+\.\d+$/), and convert all numeric IDs to strings for consistency.

Please revise the JSON accordingly so that all dependencies entries conform to the chosen type.

convex/users.ts (3)

86-103: Add authentication and ownership checks to updateUser.

Without verifying the caller, any authenticated (or unauthenticated, depending on server config) user could update arbitrary profiles by ID. Validate the caller and ensure they own the target user.

Apply after destructuring args:

   handler: async (ctx, args) => {
     const { userId, ...updates } = args;
+    const identity = await requireAuth(ctx);
+    const existing = await ctx.db.get(userId);
+    if (!existing || existing.clerkId !== identity.subject) {
+      throw new Error("Forbidden");
+    }
     
     await ctx.db.patch(userId, {
       ...updates,
       updatedAt: Date.now(),
     });
     
     return userId;
   },

---

121-153: Enforce auth and user ownership in updateUserPreferences.

Same risk as above; ensure only the owner can update their preferences.

Apply:

   handler: async (ctx, args) => {
     const { userId, preferences } = args;
+    const identity = await requireAuth(ctx);
     
     const user = await ctx.db.get(userId);
     if (!user) {
       throw new Error("User not found");
     }
+    if (user.clerkId !== identity.subject) {
+      throw new Error("Forbidden");
+    }

---

156-221: Protect deleteUser with auth and cascading ownership validation.

deleteUser currently allows deletion by arbitrary userId. This is destructive and must be gated to the owner (or an admin role if you have one).

Apply:

 export const deleteUser = mutation({
   args: { userId: v.id("users") },
   handler: async (ctx, args) => {
+    const identity = await requireAuth(ctx);
+    const user = await ctx.db.get(args.userId);
+    if (!user || user.clerkId !== identity.subject) {
+      throw new Error("Forbidden");
+    }
     // Delete all user's events

components/calendar/EventModal.tsx (1)

264-314: Associate labels with interactive controls for date pickers.

The “Start Date” and “End Date” labels use htmlFor but the corresponding Buttons lack ids, breaking the label–control association (WCAG 1.3.1/4.1.2). Add matching ids to the Buttons.

Apply this diff:

-              <Label htmlFor="start-date" className="text-sm font-medium flex items-center gap-2">
+              <Label htmlFor="start-date" className="text-sm font-medium flex items-center gap-2">
...
-                  <Button
+                  <Button
+                    id="start-date"
                     variant="outline"
...
-              <Label htmlFor="end-date" className="text-sm font-medium flex items-center gap-2">
+              <Label htmlFor="end-date" className="text-sm font-medium flex items-center gap-2>
...
-                  <Button
+                  <Button
+                    id="end-date"
                     variant="outline"

convex/events.ts (5)

58-76: Push time filters to the database; fix truthy check; avoid post-filtering after take()

• Use args.endTime !== undefined (mirroring startTime) to allow zero values.
• Push the endTime upper-bound filter into the DB query to avoid fetching extra rows and then dropping them in memory.
• Apply limit only after all filters are in place; otherwise, you can under-return results.

Apply this diff:

   handler: async (ctx, args) => {
     // Require authentication and get user
     const { user } = await requireAuth(ctx);
     
     let q = ctx.db
       .query("events")
       .withIndex("by_user_and_time", (qb) => qb.eq("userId", user._id));
 
-    if (args.startTime !== undefined) {
-      q = q.filter((fb) => fb.gte(fb.field("startTime"), args.startTime!));
-    }
+    if (args.startTime !== undefined) {
+      q = q.filter((fb) => fb.gte(fb.field("startTime"), args.startTime!));
+    }
+    if (args.endTime !== undefined) {
+      q = q.filter((fb) => fb.lte(fb.field("startTime"), args.endTime!));
+    }
 
-    const events = args.limit ? await q.take(args.limit) : await q.collect();
-
-    // Filter by endTime if provided
-    if (args.endTime) {
-      return events.filter(event => event.startTime <= args.endTime!);
-    }
+    const limit = Math.min(args.limit ?? 500, 2000); // guardrail
+    const events = await q.take(limit);
 
     return events;

Note: If multi-day events can span into the window (start before startTime, end after startTime), consider also persisting endTime for all events (see createEvent diff) and enhancing the query to return interval overlaps: event.endTime >= args.startTime AND event.startTime <= args.endTime. We can wire that up once the index supports it.

80-85: Authorization missing: getEventById can leak other users’ events

This handler does not verify ownership. A caller could read any event by ID. Require auth and check event.userId === user._id.

Apply this diff:

 export const getEventById = query({
   args: { eventId: v.id("events") },
   handler: async (ctx, args) => {
-    return await ctx.db.get(args.eventId);
+    const { user } = await requireAuth(ctx);
+    const event = await ctx.db.get(args.eventId);
+    if (!event || event.userId !== user._id) {
+      throw new Error("Event not found");
+    }
+    return event;
   },
 });

---

119-129: Authorization missing on updateEvent; validate temporal invariants

Anyone could update any event if they know the ID. Also, ensure endTime >= startTime when updating times.

Apply this diff:

 export const updateEvent = mutation({
@@
   },
   handler: async (ctx, args) => {
-    const { eventId, ...updates } = args;
-    
-    await ctx.db.patch(eventId, {
-      ...updates,
-      updatedAt: Date.now(),
-    });
+    const { user } = await requireAuth(ctx);
+    const { eventId, ...updates } = args;
+    const existing = await ctx.db.get(eventId);
+    if (!existing || existing.userId !== user._id) {
+      throw new Error("Event not found");
+    }
+    // Temporal validation
+    const nextStart = updates.startTime ?? existing.startTime;
+    const nextEnd = updates.endTime ?? existing.endTime ?? nextStart;
+    if (nextEnd < nextStart) {
+      throw new Error("endTime must be >= startTime");
+    }
+    await ctx.db.patch(eventId, {
+      ...updates,
+      endTime: updates.endTime ?? existing.endTime ?? nextStart,
+      updatedAt: Date.now(),
+    });
     
     return eventId;
   },
 });

---

131-136: Authorization missing on deleteEvent

Ensure only the owner can delete their event.

Apply this diff:

 export const deleteEvent = mutation({
   args: { eventId: v.id("events") },
   handler: async (ctx, args) => {
-    await ctx.db.delete(args.eventId);
+    const { user } = await requireAuth(ctx);
+    const existing = await ctx.db.get(args.eventId);
+    if (!existing || existing.userId !== user._id) {
+      throw new Error("Event not found");
+    }
+    await ctx.db.delete(args.eventId);
   },
 });

138-150: Require authentication in getEventsByCategory to prevent IDOR

In convex/events.ts (lines 138–150), remove the client-supplied userId arg, call requireAuth, and filter by the authenticated user’s ID. No other call sites for getEventsByCategory were found in the repository, so only this file needs updating.

Apply this diff:

 export const getEventsByCategory = query({
   args: {
-    userId: v.id("users"),
     categoryId: v.id("categories"),
   },
   handler: async (ctx, args) => {
-    return await ctx.db
-      .query("events")
-      .withIndex("by_category", (q) => q.eq("categoryId", args.categoryId))
-      .filter((q) => q.eq(q.field("userId"), args.userId))
-      .collect();
+    const { user } = await requireAuth(ctx);
+    return await ctx.db
+      .query("events")
+      .withIndex("by_category", (q) => q.eq("categoryId", args.categoryId))
+      .filter((q) => q.eq(q.field("userId"), user._id))
+      .collect();
   },
 });

In fullYear mode, the grid is 42 columns per month row, but startCol/endCol are computed from day‑of‑year (371‑wide), so events can render off‑canvas horizontally. Compute columns relative to the month row (first day of month + dayOfMonth) and limit width to the remaining days in that month. This avoids overflow and visually aligns bars to the cells.

-      if (isFullYearZoom) {
-        // For 371-column grid: use column-based positioning
-        const startCol = jan1DayOfWeek + startDay - 1
-        const endCol = jan1DayOfWeek + endDay - 1
-        left = startCol * dayWidth + headerWidth
-        width = (endCol - startCol + 1) * dayWidth - 2
-        top = eventMonth * monthHeight + headerHeight + 4
-      } else {
+      if (isFullYearZoom) {
+        // For 12×42 grid: position within the month row
+        const monthStart = startOfMonth(event.startDate)
+        const firstDow = monthStart.getDay() // 0..6
+        const dayOfMonth = event.startDate.getDate() // 1..31
+        const startCol = firstDow + (dayOfMonth - 1) // 0..41
+        const daysInThisMonth = getDaysInMonth(monthStart)
+        const daysRemainingInMonth = daysInThisMonth - dayOfMonth + 1
+        const widthDays = Math.max(1, Math.min(duration, daysRemainingInMonth))
+        left = headerWidth + startCol * dayWidth
+        width = widthDays * dayWidth - 2
+        top = eventMonth * monthHeight + headerHeight + 4
+      } else {

Note: Multi‑month spanning would ideally split into per‑month segments; this fix keeps current single‑segment behavior without rendering off‑grid.

142-167: Ensure Task Master commands are implemented or properly documented

I verified that there are no task-master entries in package.json and no CLI implementation in the repo—grep only returned references in documentation (e.g. README.md, CLAUDE.md, and docs/*.md). Before publishing these commands, you must either:

• Implement the CLI in this repository
  • Add a bin/task-master script (e.g. #!/usr/bin/env node …)
  • Update package.json with:

  "bin": {
    "task-master": "bin/task-master"
  },
  "scripts": {
    "task-master": "task-master"
  }

• Or treat it as an external tool
  • Add installation instructions and a version pin, e.g.:

  ## Install Task Master
  npm install -g task-master-cli@<version>

  • Specify the package name (e.g. task-master-cli) and minimum version.

Locations needing attention:

• CLAUDE.md (lines 142–167): lists task-master … commands without an implementation
• README.md (lines 195–199): same commands appear here
• docs/TASKMASTER_CLEANUP_STRATEGY.md & docs/CLAUDE.md: multiple task-master references

Broaden status and relax parentTaskId to match the data you’re emitting.

Current unions don’t accept "pending"/"deferred", and SubTaskAnalytics mandates parentTaskId when many subtasks omit it. This will cause type drift with tasks.json and verification artifacts.

include "pending" and "deferred" in addition to the existing values, and relax
parentTaskId so it is optional (or typed as number | undefined) on
SubTaskAnalytics so subtasks that omit a parent id do not fail type checks;
update the interface declarations accordingly wherever SubTaskAnalytics or

In tests/floating-toolbar-fix.spec.ts around lines 210 to 229, the current code
uses hasText on an input which never matches and makes the selector fragile;
replace those locators with accessibility-aware ones (use getByRole('checkbox',
{ name: /all.*day/i }), getByRole('switch', { name: /all.*day/i }), and
getByRole('button', { name: /all.*day/i }) or getByLabel(/all.*day/i) so the
accessible name is targeted), then determine visibility for each accessible
locator and click only the first one that is visible; ensure you await isVisible
with a short timeout when checking presence and then click the corresponding
visible locator.

Critical: Full-year grid coordinate ↔ date mapping is incorrect

For the 12×42 month grid, columns represent month-day slots within a 6×7 layout, not day-of-year. Current logic only covers the first ~6 weeks of the year and will fail for most months. Fix both screenToDate and dateToScreen.

In components/calendar/DragToCreate.tsx around lines 319 to 326, the overlay
currently uses "absolute inset-0" with marginLeft/marginTop which keeps
right/bottom at 0 and causes it to cover headers; replace the margin-based
positioning with explicit left/top/right/bottom offsets by removing inset-0 (or
overriding it) and set style to { left: headerWidth, top: headerHeight, right:
0, bottom: 0 } (keeping absolute positioning and z-10 and cursor classes) so the
overlay starts after the headers and does not cover them.

In components/calendar/FloatingToolbar.tsx around lines 439 to 445, the all-day
toggle is rendered as a plain button without switch semantics; update it to be
accessible by either (preferred) rendering a role="switch" element with
aria-checked set to event.allDay and keeping the same onClick handler and visual
icons/text, or by using a checkbox input (type="checkbox") visually hidden and a
labelled control for styling; ensure keyboard focus and space/enter toggle
behavior is preserved, add aria-label or aria-labelledby as appropriate, and
update any tests to query by role "switch" or checkbox as required.
