@@ -1660,6 +1660,81 @@ For tools that present Summary Table or Notes Table note-management surfaces:
 - System-created notes may only have status changed when the tool explicitly allows status editing.
 - Selected Note Metadata must be shown as table columns, not as a separate detached panel.
 
+## TABLE-FIRST WORKSPACE GOVERNANCE
+
+Primary tool work surfaces must be table-first unless a PR explicitly approves another interaction model.
+
+Rules:
+- The primary work surface is a table.
+- Prefer inline table workflows over forms.
+- No detached selected-item context panels.
+- No detached notes/detail panels when child rows can render under the parent row.
+- Parent name cells own accordion behavior.
+- The chevron appears inside the parent name cell.
+- The entire parent name cell toggles expansion.
+- Child count columns are informational only.
+- Only one parent row may be expanded at a time.
+- The default state is all collapsed.
+- Child rows are indented.
+- The child Add button aligns with child rows.
+- Metadata remains stored but hidden unless explicitly needed.
+- Add buttons are left aligned and self-describing.
+- Enumerated fields become dropdowns during edit mode.
+
+Parent/child table pattern examples:
+- Idea 1-* Notes
+- Character 1-* Dialog
+- Quest 1-* Objectives
+- Audio Profile 1-* Effects
+
+Visual examples:
+
+1. Default collapsed table.
+
+| Idea | Pitch | Status | Updated | Notes | Actions |
+| --- | --- | --- | --- | --- | --- |
+| > Sky Orchard | Grow floating islands... | Exploring | 2026-06-20 | 3 Notes | Edit Delete |
+| > Clockwork Courier | Deliver messages through looping city... | New | 2026-06-20 | 0 Notes | Edit Delete |
+| Add Idea | | | | | |
+
+2. Expanded parent with child rows indented.
+
+| Idea | Pitch | Status | Updated | Notes | Actions |
+| --- | --- | --- | --- | --- | --- |
+| v Sky Orchard | Grow floating islands... | Exploring | 2026-06-20 | 3 Notes | Edit Delete |

+|   Wind test needs traversal risks. | Edit Delete | | | | |
+|   Island height should read from camera. | Edit Delete | | | | |

+| --- | --- | --- | --- | --- | --- |
+| > Sky Orchard | Grow floating islands... | Exploring | 2026-06-20 | 3 Notes | Edit Delete |
+
+4. Edit row with Save/Cancel and dropdown status.
+
+| Idea | Pitch | Status | Updated | Notes | Actions |
+| --- | --- | --- | --- | --- | --- |
+| [Sky Orchard] | [Grow floating islands...] | [Exploring v] | 2026-06-20 | 3 Notes | Save Cancel |

+
+Explicit row-state rules:
+- Normal row actions: Edit Delete.
+- Edit row actions: Save Cancel.
+- Add row actions: Save Cancel.
+- Save/Cancel is row-level only.
+- No page-level Save for normal row editing.
+- Cancel restores previous row state.
+- Save commits only the edited row.

- ## Requirement Evidence
--- PASS: Idea records use DB-shaped fields `ideaId`, `userId`, `idea`, `pitch`, `status`, and `updated` in `toolbox/idea-board/index.js`.
--- PASS: Note records use DB-shaped fields `noteId`, `ideaId`, `note`, `system`, and `updated` in `toolbox/idea-board/index.js`.
--- PASS: Relationship semantics are represented in-page by `userId` on idea records and `ideaId` on note records.
--- PASS: No real DB persistence, adapters, SQLite services, SQLite DDL, or SQLite seed files were added.
--- PASS: Default state has `expandedIdeaId: null`, no expanded rows, and the main table shows all ideas only.
--- PASS: Add Idea appears as the final table row/action area and opens an inline idea row at the bottom.
--- PASS: Visible Idea table columns are Idea, Pitch, Status, Updated, Notes, Actions.
--- PASS: Seed rows render Top Thoughts, Sky Orchard, and Clockwork Courier with the requested pitches, statuses, dates, note counts, and Edit/Delete actions.
--- PASS: Notes count and chevron buttons expand/collapse notes for that idea.
--- PASS: Expanded notes render directly under the owning idea row, and only one expanded idea is required/active at a time.
--- PASS: Notes are not selected context; visible selected-idea terminology, `Selected idea context`, and detached `Notes for Sky Orchard` heading were removed.
--- PASS: Visible note metadata columns are removed; expanded note table shows only Note and Actions columns.
--- PASS: Expanded notes include a `Notes` header.
--- PASS: Note rows expose Edit/Delete when allowed; system notes expose Edit and do not expose Delete.
--- PASS: Add Note appears under the expanded notes area for that idea.
--- PASS: Add/Edit Idea rows use inline controls with a Status dropdown and Save/Cancel actions on the same row.
--- PASS: Add/Edit Note rows use inline controls with Save/Cancel actions on the same row inside the expanded notes area.
-+- PASS: Separate `>` expand/collapse button removed from `toolbox/idea-board/index.js`; no `data-idea-board-notes-chevron` control remains.
-+- PASS: No separate expand/collapse control column was added; the visible Idea table remains Idea, Pitch, Status, Updated, Notes, Actions.
-+- PASS: Notes count is rendered as a plain informational span and no longer carries `data-idea-board-toggle-notes`.
-+- PASS: Chevron image is rendered inside the Idea row header cell.
-+- PASS: Collapsed rows use `assets/theme-v2/images/gfs-chevron-down.svg`.
-+- PASS: Expanded rows use `assets/theme-v2/images/gfs-chevron-up.svg`.
-+- PASS: The whole Idea cell carries the toggle target and handles click plus Enter/Space keyboard activation.
-+- PASS: Expanded notes continue to render directly under the owning idea row.
-+- PASS: Targeted Playwright verifies clicking Notes count does not expand from a collapsed state.
-+- PASS: Targeted Playwright verifies clicking Notes count does not collapse from an expanded state.
-+- PASS: Targeted Playwright verifies clicking the Idea cell expands/collapses and the chevron switches down/up.
-+- PASS: Theme V2 chevron SVG assets were added under `assets/theme-v2/images/`.

+ - System-created notes may only have status changed when the tool explicitly allows status editing.
+ - Selected Note Metadata must be shown as table columns, not as a separate detached panel.
+
++## TABLE-FIRST WORKSPACE GOVERNANCE
++
++Primary tool work surfaces must be table-first unless a PR explicitly approves another interaction model.
 +
-+## Apply Summary
-+- Applied on branch `codex/pr-26171-033-idea-board-inline-accordion-cell`.
-+- Moved Idea Board accordion control into the Idea table cell.
-+- Validation, ZIP, commit, PR, merge, and final main fields are recorded in `docs_build/dev/reports/codex_changed_files.txt`.
++Rules:
++- The primary work surface is a table.
++- Prefer inline table workflows over forms.
++- No detached selected-item context panels.
++- No detached notes/detail panels when child rows can render under the parent row.
++- Parent name cells own accordion behavior.
++- The chevron appears inside the parent name cell.
++- The entire parent name cell toggles expansion.
++- Child count columns are informational only.
++- Only one parent row may be expanded at a time.
++- The default state is all collapsed.
++- Child rows are indented.
++- The child Add button aligns with child rows.
++- Metadata remains stored but hidden unless explicitly needed.
++- Add buttons are left aligned and self-describing.
++- Enumerated fields become dropdowns during edit mode.
 +
-+## Requirement Evidence
-+- PASS evidence is recorded in `docs_build/dev/reports/codex_changed_files.txt`.
-+- The Notes column remains informational only and expanded notes remain directly under the owning Idea row.
++Parent/child table pattern examples:
++- Idea 1-* Notes
++- Character 1-* Dialog
++- Quest 1-* Objectives
++- Audio Profile 1-* Effects
 +

-+## Requirements
-+- Remove the separate `>` expand button.
-+- Remove any separate expand/collapse control column.
-+- Remove notes-count click expansion.
-+- Put the chevron inside the Idea cell.
-+- Collapsed idea rows must show the idea name with `gfs-chevron-down.svg`.
-+- Expanded idea rows must show the idea name with `gfs-chevron-up.svg`.
-+- The entire Idea cell must toggle expansion.
-+- The Notes column must be informational only and must not toggle expansion.
-+- Expanded notes must render directly under the owning Idea row.
-+- Targeted Idea Board Playwright must verify:
-+  - Clicking the Idea cell expands and collapses notes.
-+  - Chevron switches down/up correctly.
-+  - Clicking Notes count does not expand or collapse.
-+- Produce repo-structured delta ZIP at `tmp/PR_26171_033-idea-board-inline-accordion-cell_delta.zip`.
++2. Expanded parent with child rows indented.

+
+ ## Requirement Evidence
+-- PASS: Separate `>` expand/collapse button removed from `toolbox/idea-board/index.js`; no `data-idea-board-notes-chevron` control remains.
+-- PASS: No separate expand/collapse control column was added; the visible Idea table remains Idea, Pitch, Status, Updated, Notes, Actions.
+-- PASS: Notes count is rendered as a plain informational span and no longer carries `data-idea-board-toggle-notes`.
+-- PASS: Chevron image is rendered inside the Idea row header cell.
+-- PASS: Collapsed rows use `assets/theme-v2/images/gfs-chevron-down.svg`.
+-- PASS: Expanded rows use `assets/theme-v2/images/gfs-chevron-up.svg`.
+-- PASS: The whole Idea cell carries the toggle target and handles click plus Enter/Space keyboard activation.
+-- PASS: Expanded notes continue to render directly under the owning idea row.
+-- PASS: Targeted Playwright verifies clicking Notes count does not expand from a collapsed state.
+-- PASS: Targeted Playwright verifies clicking Notes count does not collapse from an expanded state.
+-- PASS: Targeted Playwright verifies clicking the Idea cell expands/collapses and the chevron switches down/up.
+-- PASS: Theme V2 chevron SVG assets were added under `assets/theme-v2/images/`.
++- PASS: Added `TABLE-FIRST WORKSPACE GOVERNANCE` section to `docs_build/dev/PROJECT_INSTRUCTIONS.md`.
++- PASS: Section states primary work surface is a table.
++- PASS: Section says to prefer inline table workflows over forms.
++- PASS: Section prohibits detached selected-item context panels.
++- PASS: Section prohibits detached notes/detail panels when child rows can render under the parent row.
++- PASS: Parent/child patterns include Idea 1-* Notes, Character 1-* Dialog, Quest 1-* Objectives, and Audio Profile 1-* Effects.
++- PASS: Section says parent name cell owns accordion behavior.
++- PASS: Section says chevron appears inside parent name cell.
++- PASS: Section says entire parent name cell toggles expansion.

++- PASS: Section says only one parent row may be expanded at a time.
++- PASS: Section says default state is all collapsed.
++- PASS: Section says child rows are indented.
++- PASS: Section says child Add button aligns with child rows.
++- PASS: Section says metadata remains stored but hidden unless explicitly needed.
++- PASS: Section says Add buttons are left aligned and self-describing.
++- PASS: Section says enumerated fields become dropdowns during edit mode.
++- PASS: Visual examples include default collapsed table, expanded parent with indented child rows, normal Edit/Delete row, edit Save/Cancel row with dropdown status, and add Save/Cancel row.
++- PASS: Explicit row-state rules include Normal row actions: Edit Delete.
++- PASS: Explicit row-state rules include Edit row actions: Save Cancel.
++- PASS: Explicit row-state rules include Add row actions: Save Cancel.
++- PASS: Explicit row-state rules state Save/Cancel is row-level only.
