Subject: [PATCH 01/13] GRAPHICS.md: inline-graphics guide, companion to HAND +
 VOICE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A craft guide for drawing in GitHub PRs/docs from text alone (mermaid, math,
geojson, braille), with the empirically-verified support matrix — what renders
and what doesn't (\rule is text-mode/unsupported, \colorbox broken since 2023).
Adds toolchain/art-to-braille.mjs (shape + PNG->braille generator) and cross-links
HAND.md.

+# Graphics — an inline-rendering guide for GitHub
+
+companion to `HAND.md` and `papers/VOICE.md`. HAND governs how the code reads, VOICE how the papers sound; this governs how a **PR, issue, or repo `.md` draws** — pictures that render on github.com from text alone.
+
+it exists because the reflex is to drag in a screenshot. a screenshot drifts the moment the code moves and can't be reviewed as a diff. a diagram written *in text*, beside the change, can't drift — it versions with the thing it explains. so: prefer the mark you can type.
+
+## the one rule
+
+**if it isn't a fence or `$math$`, it doesn't render.** github runs every markdown surface through a sanitizer. know the line and you stop guessing.
+
+## what renders inline — verified on github.com
+
+- **`​```mermaid`** — diagrams *and* charts. flow, sequence, state, er, class — and `pie`, `xychart-beta`, `sankey-beta`, `quadrantChart` for data. `classDef` colors nodes (the ac chartreuse-on-black look stays in text).
+- **`$…$` / `​```math`** — equations. `\color{…}{…}` and `\bbox[bg]{…}` tint *real content*. that's the whole of what math draws — see the dead end below.
+- **`​```geojson` / `​```topojson`** — an interactive leaflet map.
+- **braille / block art in a plain `​```` ` fence** — the only way to draw *arbitrary* art inline. low-res, but anything.
+- **prose primitives** — tables, task lists, `<details>`, `> [!NOTE]` alerts, footnotes.
+
+## what does not render — and why
+
+| you reach for | what happens | because |
+|---|---|---|
+| inline `<svg>…</svg>` | stripped | sanitizer |
+| `data:` uri in `<img>` | stripped | sanitizer |
+| `<script>` / `<style>` / iframe / raw css | stripped | sanitizer |
+| math `\rule{w}{h}` pixel art | **"unable to render"** | `\rule` is a *text-mode* tex command; mathjax implements only math-mode macros |
+| math `\colorbox{…}{…}` grid | broken | broken on github since may 2023, not restored |
+| `\begin{array}{@{}c@{}…}` + `\\[-Npt]` | **"unable to render"** | the `@{}` column spec and negative row gaps aren't supported |
+
+**the trap:** every `\textcolor{red}{\rule{…}}` "colored square" example on the web is a *native-latex → png* tool (readme2tex and kin). those commit an image. they do not work in github's mathjax. don't chase them — i did, it's a dead end.
+
+## draw anything inline: braille
+
+`\rule` is gone, so arbitrary art comes down to **unicode braille** (U+2800–28FF). each glyph is a 2×4 dot grid, so a generated field of glyphs is a 1-bit raster that renders anywhere monospace. `toolchain/art-to-braille.mjs` does it from a shape or from any png:
+
+```
+node toolchain/art-to-braille.mjs smiley
+node toolchain/art-to-braille.mjs flower
+node toolchain/art-to-braille.mjs image pic.png 50 [--invert]
+```
+
+it shells out to `sips` to normalize/resize, decodes the png with node's built-in `zlib` (no image library), thresholds luminance, packs the dots. a smiley:
+
+```

+```
+
+limits: low resolution, 1-bit (no grayscale or color), and it wants a monospace font with braille coverage. right for icons, logos, mascots, diagram-art — wrong for photos. for a photo, you've left inline-only: commit a code-generated svg/png and reference it by path.
+
+## picking a method
+
+```mermaid
+flowchart TD
+  q{show what?} --> d{flow / state?}
+  d -->|yes| mer[mermaid diagram]
+  d -->|no| c{quantities?}
+  c -->|yes| chart[mermaid chart]
+  c -->|no| f{formula?}
+  f -->|yes| math[math block]
+  f -->|no| g{geographic?}
+  g -->|yes| geo[geojson]
+  g -->|no| br[braille — shape or png]
+```
+
+label nodes with the real names — `disk.mjs`, `session-server`, not "service a". a diagram that names the code is navigable; boxes of abstractions are decoration. (same instinct as HAND: knowability first.)
+
+## the papers caveat
+
+none of this reaches the `papers/` xelatex pdfs — mermaid and mathjax are a github.com feature. in a paper the equivalents are native and better: tikz for diagrams, real latex math, `pgfplots` for charts, `\includegraphics` for raster. this guide is for the github surface — prs, rfcs, issues, readmes.

 it exists because of what *The Hand and the Loop* (`papers/arxiv-hand-and-loop`) found: across three eras the codebase gained velocity and breadth and lost the instrument — the terse, single-mind discipline of the hand-written years. this guide is how the hand gets handed back to the loop. an agent that reads this should write code that knows it's part of an instrument, not just code that runs.

Native-capture complement to puppet (which only sees the browser via CDP):
frame observes the whole screen of any fleet Mac, puppet acts. Folded into the
menubar app (FrameCapture.swift) so it reuses the app's Accessibility trust and
GUI-session WindowServer access; captures in-process via ScreenCaptureKit (no
screencapture subprocess, no launchd throttle), runs Vision OCR with click
coords, walks the AX tree, downscales a thumbnail. Permissions are lazy: the
app never prompts at launch; the first frame request triggers Screen Recording.

bin/frame + frame.mjs: frame <machine> [--no-ocr] / doctor / setup / list,
config-driven from the shared ~/.config/slab/puppet.json.

install.sh: stable self-signed identity in a dedicated keychain, cert created
once and reused, signing done in the Aqua session — so TCC grants (Screen
Recording + Accessibility) survive rebuilds instead of resetting under ad-hoc.

+// frame.mjs — capture a rich "frame" of a remote Mac for fleet automation.
+//
+// A frame = pixels (a downscaled JPEG thumbnail) + OCR'd text with click
+// coordinates + the Accessibility element tree (roles/titles/AXPress targets)
+// + window/cursor/frontmost state, packed into one JSON envelope. It is the
+// native-capture complement to `puppet`: `frame` OBSERVES the whole screen
+// (any native app, no DOM needed), `puppet` ACTS (trusted stroke/gesture/key).
+// Together they close an observe→act loop across the fleet.
+//
+// The capture is produced ON the target by the SlabMenubar app (see
+// FrameCapture.swift) — it already holds Accessibility trust and lives in the
+// GUI session, so it can reach the WindowServer that a plain ssh session
+// cannot. This CLI just drops a request file over SSH and reads the result.
+//
+// PERMISSIONS ARE LAZY: the app never prompts at launch. The first real frame
+// request is what triggers the Screen Recording grant on the target; until
+// granted, the envelope reports `capture: "permission_needed"` and `frame
+// setup <machine>` walks you through the one-time toggle.
+//
+// This file ships in the PUBLIC aesthetic.computer repo, so it carries NO
+// machine names: the registry lives in the UNTRACKED config shared with
+// puppet at ~/.config/slab/puppet.json. A machine's name doubles as its ssh
+// host (the minis are ssh aliases); set "sshHost" per machine to override.

Subject: [PATCH 05/13] slab menubar install.sh: harden stable code-signing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The stable-sign path was failing on machines with a legacy same-CN cert in
login.keychain (blueberry) and falling back to ad-hoc — which resets the TCC
Screen-Recording/Accessibility grants on every rebuild. Three root causes:

1. Ambiguous identity. codesign --sign "<CN>" errors 'ambiguous (matches … in
   login.keychain and … in slab-signing.keychain)' when a dup exists. Now sign
   by the cert's SHA-1 HASH read from the dedicated slab-signing keychain
   specifically (new slab_sign_hash helper + hash lookup in the gui-bootstrap
   helper), so the right cert is always picked. find-certificate -c keeps
   guarding existence.

2. Spurious ad-hoc fallback from a SIGPIPE/pipefail interaction. The post-sign
   verify piped 'codesign -dvv' into 'grep -q'; under set -o pipefail grep -q
   closes the pipe on first match, codesign takes SIGPIPE and exits non-zero, so
   the pipeline reported failure even when the signature matched. Capture to a
   var and pattern-match instead.

3. Removed a kickstart -k I briefly added — it double-ran the gui job and the
   two runs raced the same bundle. RunAtLoad starts it once; the completion-
   marker wait is sufficient. Pre-create the log so the marker gate polls from
   t=0; make set-keychain-settings best-effort.

Verified on blueberry: adhoc -> Authority=Slab Menubar Self-Signed across three
consecutive install.sh runs, same cert SHA-1 each time (idempotent), with the
login.keychain dup still present.

AX is independent of the screenshot, so run it on a concurrent queue and join
after capture+OCR — wall-clock becomes max(ax, capture+ocr) instead of the sum.
--fast switches Vision to .fast recognition for ~5x quicker OCR at some accuracy
cost on small text. timings_ms now also reports 'wall' (serial part).

Subject: [PATCH 09/13] slab/frame: opt-in persistent server (held per-machine
 ssh agents over a unix socket)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A long-lived consumer that holds the socket open avoids per-call node cold-start
and connection setup: steady-state --fast frames drop ~440ms→~280ms (~35%), full
~650→530ms. Started explicitly with 'frame server' (the CLI uses it only if
running — for one-shot calls it's no faster than direct, since ControlMaster
already amortizes ssh, so we don't auto-spawn a daemon). 'frame stop' to halt;
'--direct' forces a one-shot ssh. Remaining held-socket cost is the AX walk
(~150ms, now the daemon limiter) + the 248KB envelope transfer.

Subject: [PATCH 10/13] slab/frame: transfer the JPEG as raw bytes, not base64
 (ACF1 length-prefixed frame)

Daemon writes the thumbnail to a sidecar frame.out.jpg (no thumb_jpg_b64 in the
envelope). Transport frames it as 'ACF1 <jsonLen> <jpgLen>\n<json><jpg>' across
all paths (held agent, server->consumer socket, one-shot direct). Kills the
base64 +33% inflation (225KB->148KB on the wire) and the encode/decode CPU;
verified the JPEG survives the agent->server->consumer double-hop intact.

Subject: [PATCH 11/13] slab/frame: batch AX attribute fetches
 (AXUIElementCopyMultipleAttributeValues)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The walk did ~6 separate AX IPC round-trips per node (role/children/title/value/
desc/position/size), each a sync Mach call into the target app — ~2000 IPCs for
a 300-element tree. Batch all seven into ONE call per node; AXActionNames stays
separate but only for matched elements. AX walk on Chrome's ~320-element tree:
~200ms -> ~120ms (~40%). Since AX runs parallel to capture+OCR it's the --fast
daemon limiter, so this is the wall.

FramePreview.swift mirrors VideoViewer/PdfViewer: watches state/open-frame
(path\tmachine lines), opens a chromeless glass panel per machine showing the
captured JPEG, live-reloads on rewrite, and draws the source machine name in a
top-left HUD chip (same material/radius/mono style as the other viewers, but
the machine — not a session emoji — leads, since a frame answers "whose screen
is this"). Wired into AppDelegate.refresh()'s consume pass next to pdf/video.

frame.mjs gains an opt-in --preview flag (and a 'frame view <machine>' verb):
after writing the JPEG it appends path\tmachine to state/open-frame so the
local menubar raises/reloads the badged window. Bare 'frame' calls never pop a
window. Skips when capture was permission-blocked (no pixels to show).

Subject: [PATCH 13/13] FramePreview: open small + resizable, image
 aspect-fits, badge pinned

The frame panel was sizing by screen height like the portrait pdf/video
viewers, but a frame is a LANDSCAPE desktop (~1568x882) so it spanned the
display. Worse, NSImageView's intrinsicContentSize is the image's pixel
size, which (with the edge-pinned constraints) dragged the window out to
the native frame size regardless of the contentRect.

- idealFrame: target a small default WIDTH (~38% screen, 640pt floor,
  60% cap), derive height from the frame aspect, clamp height to 60% of
  screen, and corner-anchor top-right with a 24pt inset (no full-bleed).
- Drop the imageView's content hugging + compression resistance to
  .defaultLow so it no longer forces the window to the native pixel size;
  the image just scales to fit (.scaleProportionallyUpOrDown).
- panel.minSize + contentAspectRatio so drag-resize scales the image and
  keeps the frame's proportions.
- isRestorable = false so a stale saved frame (e.g. from a since-
  disconnected display) can't override the small default.

Badge stays corner-pinned (fixed-height leading/top constraints) and all
existing behavior (live reload, per-machine keying, Esc/Cmd-W, glass) is
unchanged. Verified on neo against chicken: opens 640x360, resizes with
aspect held, 'chicken' badge stays top-left.
