* An image's or a terminal's tag says petscii:on when it is drawn as glyph ↵Gabriel Schneider16 hours

* A dump no longer embeds a picture or a PDF that is on disk: Restore reads it ↵Gabriel Schneider19 hours
| | | | | | | | | | | from there, as a clean file's text is Every Dump carried each image's and PDF's bytes in base64 (a 900 KB PDF made a 1.3 MB dump), and a Restore showed that copy however the file had changed. One on disk now goes by its path alone; one not on disk (no file behind it) still has its bytes kept. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pane's ctl read says Collapse and a PDF's PdfFit and PdfTint (`collapsed`, ↵Gabriel Schneider21 hours

The ctl read ends with `collapsed` when it is, and a PDF's `fit:` and `tint:` in the words PdfFit and PdfTint take; the dump's image record carries pdf_fit and pdf_tint (empty in older dumps: the defaults).

* A terminal's kitty graphics draw as glyph art where pixels cannot, and by ↵Gabriel Schneider29 hours
| | | | | | | | | | | | | | | | | | | | choice: Petscii on the pane, TermImages for new ones Under an outer terminal without kitty graphics a tty pardes cannot pass a terminal pane's images on, so it draws them itself as an image pane's Petscii does: each row of an image is matched to C64-palette glyph art over the cells it covers (GlyphArt.renderRect, the exact-grid half of GlyphArt.render), cached while it is on screen. yazi is still told the kitty protocol works, so it keeps sending its previews. The same art is a choice anywhere: the Petscii builtin now takes a terminal pane too (PaneKind.picture), flipping its images between pixels and glyphs, and a terminal holding images, or drawing them as glyphs by choice, says petscii:on|off in its tag as an image pane does. TermImages real|petscii (default real) is what a new terminal starts with; it is in DumpConfig, /ctl and the reference. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Dumps and init files from before 0.0.4 load no more of their old tag ↵Gabriel Schneider29 hours
| | | | | | | | formats, and three orphan test scripts go A2: a restored pane's tag tail comes from the dump's tag_tail, which every dump since 0.0.4 writes; the 27 earlier default tails that were recognised to upgrade, restoreTail, tailClass, savedPrefix and restoreTailAt, pdf_view's and image's legacySavedPrefix, a terminal's TTY tag prefix and its raw output tail replay, and the ThemeSel, FontSel and ColumnTags words (init lines and dumped output names) go, with their tests; the CHANGELOG says so. A4: test/fs_soak.py, referenced nowhere (monkey9p.py does its work). A6: test/column_grip.py and test/look_placement.py, referenced nowhere; the six review scripts docs/ui-review.md names stay.

* A look at a corrupt image fails with an err rather than open a blank paneGabriel Schneider29 hours
| | | | | | An image stb_image could not read opened as an empty image pane, the look succeeding. The bytes' header is now checked at the look (stbi_info_from_memory), and one that is no image it reads fails the look, look: <path>: not an image pardes can read, making no pane.

* Paint into a target Surface instead of swapping the frame's outGabriel Schneider29 hours
| | | | | | | | | The painters of a pane's body and tag (renderBody and its selection, gutter, syntax, ANSI and wrap-marker passes; paintPaneTag; paintHeaders; renderPane; the image and PDF grid paths) take the Surface they paint as a parameter. The body layer and the tag layers paint straight into their own temporary surfaces, and the std.mem.swap of p.surface around those calls is gone. No behaviour change.
* Move the Image pane namespace out of panes.zig into image.zigGabriel Schneider29 hours
| | | | | | | | | | | | | Pure move: the body of `pub const Image = struct { ... }` now sits at the end of image.zig, dedented, under a "the image pane" banner, so the image thing (decoding, glyph art, and the pane that shows it) is one file. Its nine `image.X` self-references lose the prefix; image.zig gains the four imports the pane code uses. panes.zig keeps `pub const Image = @import("image.zig");`, so `panes.Image.x` callers are unchanged. image.zig joins the embedded source list, since the pane code left panes.zig which was on it.

* Refactor panes and filesystem; replace FUSE with 9PGabriel Schneider2026-09-07
| | | | | | Consolidate pane, layout, memory and host code. Serve 9P by default over Unix sockets, with runtime mounts and optional TCP/QUIC transports. Remove FUSE and obsolete proof-of-concept examples. Fix highlighting and terminal-history performance, expand differential and stress-test infrastructure, sort navigation results while preserving the next occurrence, add syntax-colored Braille minimaps, remove SPC-k, and document 9P interaction as a repository skill.
* A fourth platform: pardes as ESP32-P4 firmware, bytes in and bytes outGabriel Schneider2026-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `-Dplatform=p4 -Dtarget=riscv32-freestanding` emits a single freestanding OBJECT exporting a seven-function C ABI, not an executable. The board's toolchain (../05-zig-p4) owns `_start`, the linker script and the UART driver and links this in. The seam is bytes rather than types, so neither side can accidentally depend on the other's internals, and a signature that drifts fails at link time. The serial line is the whole of the I/O. `src/p4.zig` drives vaxis unchanged over it: the renderer is a byte writer and `queryTerminalSend` is a byte writer, so the terminal emulator on the host answers the capability handshake and the firmware sees a real terminal. Measured going out over the wire on attach: alt screen, in-band resize, cursor report, kitty keyboard, kitty graphics, DA1. THREE WORDS EXIST ONLY HERE. `src/board_memory.zig` implements `Peek`, `Poke` and `Hexdump`, gated on `builtin.os.tag == .freestanding and !isWasm()` - derived from the TARGET, because they are a property of running with no OS under you rather than a product option, and because wasm is freestanding too and is exactly what must be excluded: in a browser an address is an offset into the linear memory this editor's own heap lives in. Every access goes through `*allowzero volatile`: a peripheral register is not memory, and address 0 is an ordinary unmapped address on this bus. One 4 KiB cap per command, set by the console rather than the memory - an unbounded dump would wedge the only console the board has for eleven hours. Measured on ESP32-P4 rev v1.3 silicon, driven from a host terminal: Peek 0x501101a4 0x0e63ce71, then 0xaeaa6919 on a second read - the RNG register, so the volatile loads are not folded Poke 0x5011002c 0xdeadbeef LP_STORE0; a later Peek returned 0xdeadbeef Hexdump 0x5011002c 32 16 bytes a row, hex columns and an ASCII gutter Peek 0x50110001 `peek: MisalignedAddress` on the message row That last line is the one that matters. A misaligned 32-bit access traps, and a trap in firmware is a watchdog reset that takes the session with it, so the check that turns it into a message is the reason the file is hand-written rather than a generic reader. BARE METAL BOOTS AN EMPTY OUTPUT BUFFER. Every other boot layout in `init` makes a shell, and on this platform that is not a preference but an impossibility: nothing to fork, no pty to give a terminal pane. Booting one anyway produced precisely what that describes - a pane whose tag ends in `Filter`, no gutter, no buffer, and every keystroke vanishing into the Fallback's silent pty. An output buffer is also what the platform's own words want, since Peek, Poke and Hexdump each fill one. Sized for the board rather than for a desktop: * `allocators.zig` gains a p4 tier that is ALL fallback - every capacity is zero, so each arena spills immediately to the 384 KiB heap the firmware hands over, and no megabyte-shaped static reservation lands in `.bss`. * `source_manifest.zig`'s allowlist is EMPTY on p4. The table is ~0.95 MiB of rodata against a 1.5 MiB flash partition; the firmware's filesystem is the serial host's, through the Host vtable. * The grid is clamped and the clamp is measured, not guessed: every cell is paid for four times (vaxis Screen + InternalScreen, pardes Surface + previous_cells), so 40x12 fits and 80x24 exhausts the heap during `Pardes.init`. * `Vaxis.resize` deinits both screens before allocating replacements, so a failed resize leaves vaxis rendering nothing. The p4 shell keeps the previous geometry on failure instead of leaving a half-applied one. Also here: `output_pane_integration_test.zig` had an exhaustive switch over `Platform` that adding `.p4` left unhandled, which broke `zig build unit-test` outright - the native test binary is the one consumer no platform build compiles. 346 tests pass again.

* pardes v2: the rewrite, complete and organized. src/ (core + three shells), ↵Gabriel Schneider2026-08-01
test/ (snapshot parity harness + 18 frozen goldens). One sans-IO core, vaxis tty + SDL3 GPU native + wasm web shells, 18/18 parity with the purged prototype, 7.6k lines vs 12.1k. Fix: gui shell pre-sized the core at init so the greet-releasing resize never fired (blank panes until first interaction); live sessions now init at defaults and get the real grid as a resize event (the shell contract, documented on Options).
