+## Session Developments & Achievements
+
+During this session, we successfully built out and verified several core architectural features of the Ledgerrz application:
+
+1. **BEM Styling Refactoring (BDSM Theme first)**:
+   * Replaced inline Tailwind classes across all core Vue pages and layout components (`Dynamics/Index.vue`, `Dynamics/Create.vue`, `Dynamics/Show.vue`, `Ledgers/Show.vue`, `ParticipantsList.vue`, `LedgerList.vue`, `CreateLedgerForm.vue`, `AddMutationForm.vue`, and `MutationList.vue`) with structured BEM scoped CSS blocks.
+   * Utilized Tailwind v4 `@apply` and `@reference` inside `<style scoped>` blocks to prevent code duplication, enforce a dark-first BDSM aesthetic, and maintain clear separation of concerns.
+
+2. **Ledger Alignment & Scoring Logic**:
+   * Added an `alignment` column (`positive`, `neutral`, `negative`) to Ledgers, affecting the color coding of mutations:
+     * *Positive Alignment*: higher score is better; additions are green (+), demerits/deductions are red (-).
+     * *Negative Alignment*: lower score is better (demerits); deductions are green (-) as they reduce demerits, and additions/infractions are red (+) as they increase demerits.
+     * *Neutral Alignment*: standard scoring, styled in gray/neutral colors.
+   * Added an "Alignment" dropdown selector in the ledger creation form.
+
+3. **Demerit Authorship Correction**:
+   * Corrected database seeders so demerits/penalty mutations are authored by the Dominant/Owner user (`alice` or `testUser`) rather than the submissive (`bob`), aligning with realistic power exchange dynamics.
+
+4. **Read Cursor & Dashboard Activities Highlights**:
+   * Designed and built a polymorphic `read_cursors` table to track a user's last-viewed timestamp on individual Dynamics and Ledgers.
+   * Developed `ActivityService` to chronological sort and partition dynamic activity (messages, ledger creation) and ledger activity (mutations, approval updates, and comments) into unread vs. read categories.
+   * Highlighted unread entities grouped together on the user's dashboard, displaying the **last two already-read items as muted context** followed by highlighted unread activities with a prominent `NEW` badge.
+   * Visiting a Dynamic/Ledger automatically updates its read cursor, removing it from subsequent dashboard loads.
+   * Dynamically shared the unread entity count as a global Inertia prop, rendering a vibrant red dot notification badge over a bell icon in the top-right of the header.
+
+5. **Broadcasts, Environment & Verification**:
+   * Configured real-time notifications utilizing Laravel Reverb.
+   * Documented CLI environment test pollution learnings inside `AGENTS.md` to prevent future CSRF `419` errors.
+   * Ensured full production assets compilation (`npm run build`) and achieved **45/45 passing Pest PHP tests with 206 assertions**.
