The Git tab fills in — the parked postures rehome whole, and the strip's membership is the posture

The popover's third tab settles (03 ▸ Git tab, 2026-08-07): BoardGitTabView
takes the parked section — the six-posture matrix, the Pro pointer, the
nested/unverifiable prose, the branch controls, the Board Settings… door —
with the tab label doing the old "Git" header's naming work, and one new
caption for the no-repository posture. BoardInfoTab.available drops the Git
tab exactly where BoardGitSection resolves absent, carrying 12's
absent-no-placeholder rule up to the tab strip; selection resets to Info per
open, now a ruling. Daily face only — the remote block still joins with
pro-m2.

 ## Board popover
 
-**Restructure in progress (2026-08-07): the popover is going tabbed.** The symbol/name header stays at the top; below it sit three tabs — **Info**, **Theme**, **Git** — each the settings surface for one aspect of board configuration, each designed in its own dedicated session (Git is an empty placeholder until its; Info and Theme are settled). The bullets below describe the popover's pre-tab content; what of it rehomes into which tab — and where the git section lands — is the Git session's to settle. The rulings inside the bullets (rename semantics, the git postures, the popover/sheet split) stand; only their placement is in motion.
+**The tabbed popover (2026-08-07, restructure complete — all three tab sessions settled).** The symbol/name header stays at the top — the board's glyph with its tint row beside the rename field; below it sit tabs — **Info**, **Theme**, **Git** — each the settings surface for one aspect of board configuration, each settled in its own dedicated session. **Tab membership is the git posture's** (the Git session's ruling): the Git tab joins the strip only when the git section has something true to say — `BoardGitSection` resolves to anything but absent — so a free-tier board with no `.git` shows Info | Theme alone. This carries 12-editions.md's "absent, no placeholder" rule up to the tab strip: a standing Git tab on every free board would be the standing ad for Pro that 12 forbids. **Selection resets to Info on every open** (ruled in the Git session, closing the question the earlier tab sessions deferred): the popover is transient and Info is the board's face — and a remembered tab could strand selection on a tab the next posture doesn't offer.
 
 **The Theme tab** (settled 2026-08-07, its dedicated session; reworked same day from the first "Background" cut — the style-editor embed was in, then ruled out): a **preset-only** surface — no palette grid, no "Board" subtitle, no manual controls (the manual surface is Style… with nothing selected; the raw file remains the image escape hatch). One **Solid color / Pattern** segmented choice at the top, then the filters that apply to the chosen kind, then one carousel of the eight wheel hues with tall skinny chevrons flanking it (compact-chevron paging buttons, ~three swatches per press, each disabling at its end of the strip). **Solid color** shows Tone (defaults to the current appearance) and Saturation only; the carousel holds flat swatches — each hue at the selected tonality's base saturation and lightness, exactly the primary color the matching facets recipe would write — and clicking one sets `background.color` and *removes* `background.image` in one write (the generated PNG stays on disk so undo can restore the field that pointed at it). **Pattern** is the faceted-background picker (DESIGN/explorations/board-backgrounds.md ▸ Faceted gallery, the reviewed recipe): four filters — Tone and Saturation shared with Solid, plus Colors mono/duo/trio and Mesh coarse/medium/fine — over rendered previews, one seed per hue, plus a Reroll button that re-mints the seeds (filters change the treatment, Reroll the geometry; preview and file share a seed, so what's clicked is what lands). Clicking a pattern swatch renders the recipe at the 3072 px decode ceiling off-main and lands it in one write: the PNG into the board root as `facets.png` (Finder-ladder rename only when a foreign file owns the name), `background.image` pointed at it, and `background.color` set to the recipe's primary color — the underlay that stands in while the image decodes or if the file ever goes missing. The mode opens on whichever kind the board currently wears (Pattern when `background.image` is the generated file, Solid otherwise). **Backgrounds ship as static pixels, never live-rendered views** (the perf/sync ruling, 2026-08-07): the generator runs at pick time, the render loop only ever composites a decoded bitmap. Native undo restores the two fields, not overwritten bytes — regenerating over our own PNG is destructive, documented, and accepted. The whole tab disables under the read-only lock as one surface.

 The board's vital statistics, read-only, in two registers with one honest split: **model facts** off the live snapshot — Lanes, Cards, Attachments — counting *the board you see* (the welcome-count live-only rule; the Cards row grows a quiet "· N in Trash" tail only when the trash holds anything, counting freight the way the purge confirms do — never a standing "0 in Trash"); and **disk facts** off one background whole-folder walk — File (the `.board` folder's name), Files, Size, Created, Modified — counting *everything*, `.git` and `.trash/` included, because their job is to agree with Finder's Get Info about the same folder (a size that quietly excluded the repository would send a user hunting for missing gigabytes). Disk facts are honest-as-of-appearance, refreshed per tab visit, never live — `FolderWatcher` filters `.git` churn out of the reload stream by design, so there is no event they could honestly hang off, and a ticking size is motion without meaning on a settings surface; an em dash holds each disk row until the walk answers. Modified is the tree's newest content-modification date, directories included (a deletion-only change moves no file's mtime, only its parent folder's); Created is the folder's filesystem birth date, not frontmatter — the folder may predate any stamp in it. A **Reveal in Finder** link closes the tab — the rows describe the folder, and this is the door to it; not disabled under the read-only lock, since revealing is not a mutation.

+### Git tab (settled 2026-08-07)
+
+The pre-tab closing git section rehomed whole — **the daily face, and only that** (the 2026-07-31 popover/sheet split stands; a repository-facts dossier in the Info register was considered this session and declined — the popover's git surface is for operating, and per-item history is the card History section's). The postures (06-history-undo.md ▸ Rules; 12-editions.md) render one tab surface each, with the tab's own label doing the work the section's "Git" header used to:
+
+- **Free + inert `.git`** → the contextual one-line Pro pointer (12-editions.md — still the app's one in-context pointer to Pro, and still shown only where it is true).
+- **Pro, no repository** → one caption stating the fact above the **Board Settings…** door — the header-plus-door posture blessed 2026-08-06, restated for a surface whose header is now the tab label; the door stands exactly where a user looking for git will look.
+- **Repo-nested** and **unverifiable** → their settled prose, no door (nothing setup-shaped can apply).
+- **Git mode** → the branch display with the **switch picker**, the abnormal-state notes (paused, unreadable, switch failure — 06), and the **Board Settings…** door; on remote-backed boards, remote tracking (ahead/behind) with **Pull/Push** controls and the status badges (Authentication needed, queued pushes, last error — the badge points at the sheet, capture happens there) join as one more block under the branch controls (07-sync-collab.md's cards, unchanged by the rehome).
+- **Absent** (free, no `.git`) → no tab at all — membership is the posture (the tabbed-popover paragraph above).
+
+**A single-branch board's picker opens onto a disabled explanatory row** (ruled 2026-08-06, built with the tab): with creation relocated to the sheet, the menu holds only the *other* local branches, and an empty menu reads as broken — a disabled "No other branches" row teaches both why the menu is empty and where creation went. The Board Settings… row remains the popover's one setup affordance, shown only where the sheet is reachable; each control keeps exactly one home across popover and sheet.

+The window-title widget opens the **board popover** — the one board-level surface. Its header hosts, on every board:
 
 - **Board rename** (settled: this function stays in-app, unlike the pathfinder which dropped it with the inspector). Rename edits the board's frontmatter `title` only — the folder is never renamed by the app; the Finder document name is Finder's to change (01-storage-format.md's board-naming rule). A foreign rename landing while the popover is open resyncs the field from the snapshot only while the field is unfocused — a focused field keeps the user's keystrokes, the dirty-buffer courtesy applied here (settled).
-- **Board styling** — the embedded style editor (Styling ▸ Controls above).
-- **Git at a glance** — Pro tier surface, mode-aware, *display and daily operations only* (re-ruled 2026-07-31 — setup moved to the board settings sheet below; in the free tier this section is absent on ordinary boards and reduces to the contextual one-line Pro pointer on boards carrying an inert `.git` — 12-editions.md): the posture lines (repo-nested explanation, unreadable-repo and paused states — 06), branch display with the **switch picker**, and on remote-backed boards remote tracking (ahead/behind) with **Pull/Push** controls and the status badges (Authentication needed, queued pushes, last error — the badge points at the sheet, capture happens there). **A single-branch board's picker opens onto a disabled explanatory row** (ruled 2026-08-06): with creation relocated to the sheet, the menu holds only the *other* local branches, and an empty menu reads as broken — a disabled "No other branches" row teaches both why the menu is empty and where creation went. A **Board Settings…** row opens the sheet — the popover's one setup affordance. **The Pro mode-none posture is header plus that door** (blessed 2026-08-06): with no repository the section stays — "Git" and the Board Settings… row alone — rather than vanishing, so the board's git story keeps its named place in the popover and the door stands exactly where a user looking for git will look.
+- **The board glyph** — the symbol picker with its tint row beside the rename field owns the board's `icon`/`iconColor` (Styling ▸ Controls above); manual board styling beyond the glyph is Style… ⌥⌘S with nothing selected, and the Theme tab owns the preset backgrounds.
