Active work — cross-machine resume ledger

Snapshot: 2026-07-22. This file records volatile work that has not landed on main. Read it after docs/agent-handoff.md. Remove completed entries when their PR merges; do not let this become a second permanent backlog.

Repository authority

  • Canonical development URL: https://github.com/levineuwirth/pmacs.git. This ledger uses the normalized local alias githubsucks so its refs and recovery commands are identical on every machine. Remote names are otherwise machine-local: origin may name this canonical URL, a release mirror, or something else, and therefore has no authority by name alone.
  • Canonical base at this snapshot: githubsucks/main @ 1dd47fc (modeline detection #132 merged atop Vterm Stage 2 #130; protocol v18).
  • On the transfer source, origin/main named a release mirror at d3fa632 and lagged badly. On the current destination, origin names the canonical URL. This difference is why all recovery begins by verifying URLs and normalizing githubsucks rather than trusting origin/main.
  • The shared desktop checkout contained unrelated uncommitted work. The branches below were prepared in isolated worktrees; never clean or overwrite the shared checkout to recover them.

Start on another machine by inspecting its remotes:

git remote -v
git remote get-url githubsucks

If the second command says the alias is absent, add it; if it prints a different URL, stop and resolve that collision rather than overwriting an unknown remote:

git remote add githubsucks https://github.com/levineuwirth/pmacs.git

Then recover current refs:

git fetch githubsucks --prune
git log -1 --oneline githubsucks/main
git worktree list
git status --short --branch

The first command must expose 1dd47fc or a newer intentional main. If it does not, stop and repair the remote/fetch configuration.

Vterm Stage 3 implementation lane

  • Portable branch: githubsucks/vterm-gpu
  • Framing carried as the first commit; implementation follows it.
  • Base: canonical main @ 1dd47fc (modeline detection #132 atop Vterm Stage 2 #130). Cut from main, NOT stacked on vterm-stage3-framing, per the framing's §8.
  • PR: #135, https://github.com/levineuwirth/pmacs/pull/135, open against canonical main. Never merge without explicit authorization.
  • State: criteria 28-37 implemented. Protocol v19 (SUPPORTED=[6..=19]): InstanceMessage::TerminalFrame (discriminant 26, daemon-gated), FrontendEvent::TerminalResize (11) and TerminalPointer (12) (frontend-gated). pmacs-protocol/src/terminal.rs owns the shared bounds and TerminalFrame::validate; pmacs-gpu/src/terminal.rs is the pure cell-space paint planner; pmacs-gpu --headless-probe drives the real attach client without winit for criterion 37.
  • Verification (clean tree, this machine):
    • cargo fmt --check;
    • cargo clippy --workspace --all-targets -- -D warnings;
    • cargo test --lib: 1,757 passed (3 ignored);
    • cargo test --lib --features crdt: 1,933 passed (3 ignored);
    • vterm Stage 1 acceptance: 9 default / 10 CRDT;
    • vterm Stage 2 acceptance: 4 default / 4 CRDT;
    • vterm Stage 3 acceptance: 4 default / 5 CRDT (the CRDT-only case is the real-daemon + real-PTY + headless-GPU path);
    • statusline acceptance: 7 default / 8 CRDT;
    • cargo test --test m4_acceptance -- --skip basedpyright: 120 passed (3 ignored, 1 filtered);
    • PMACS_REQUIRE_GPU=1 cargo test -p pmacs-gpu: 127 passed;
    • cargo test --workspace -- --skip basedpyright: 2,919 passed across 83 suites (19 ignored), one invocation;
    • git diff --check.
  • Review round 1 addressed (framing §0.10): hover no longer claims durable terminal control (real defect, bite-verified); terminal motion dedupes by cell; declarations record only once sent; unchanged frames skip revalidation; the terminal-mode presence-sweep skip is removed. The review's predicted presence FREEZE did not reproduce — the buffer-follow clears the declaration before render_frame, so a truthful sweep always precedes terminal mode; that test is a labelled regression guard, not fix evidence.
  • Review round 2 addressed (framing §0.11): a daemon disconnect now leaves terminal mode so the notice is visible (real defect, hand-verified because fix and test share a file); the per-tick full-grid clone is gone; inbound terminal events require a negotiated v19 session; a grid-missing press no longer arms a drag; roadmap/handoff Arc 5 lines corrected. Named deferral: terminal wheel gestures discard scroll magnitude.
  • Post-round-2 gates: 1,758 default + 1,934 CRDT library tests; required GPU 129; workspace sweep 2,923 across 83 suites; Stage 3 acceptance 5 default / 7 CRDT; M4 120; fmt, clippy, diff check clean.
  • Closed caveat: the once-seen required-GPU failure did not reproduce in eight author runs plus five reviewer runs. Treated as environmental.
  • Next: further user review rounds on the PR.

Cross-PR coordination: #135 and #137 overlap

Two PRs are open against canonical main at once and they touch the same files. Neither lane copies from or merges the other. PR #137 (tab-width-parity, "feat(render): unify tab-width projection") is APPROVED and FROZEN at 5b23e11; this lane must not cherry-pick, merge, or otherwise absorb it.

Whichever PR lands SECOND rebases onto the canonical resulting main and reruns the COMPLETE gate suite — not a subset, and not the pre-rebase results. The overlap is in the renderer and the protocol crate's export surface, so a clean textual merge does not imply a correct one.

Overlapping paths, and why each one collides:

Path #135 (vterm stage 3) #137 (tab width)
pmacs-gpu/src/main.rs terminal mode: State fields, render-batch swaps, input branches, headless probe tab-width projection in the same renderer
pmacs-protocol/src/lib.rs pub mod terminal + the terminal re-export block its own added export
Cargo.lock unicode-width promoted to a workspace dep for pmacs-protocol a pmacs-gpu dependency change
docs/active-work.md, docs/agent-handoff.md this lane's entries and §1 snapshot its own entries

Cargo.lock and the docs are mechanical. The two source files are not: both PRs edit the GPU renderer's measurement/paint path, and both widen pmacs-protocol's public surface in the same pub use region. After the rebase, re-read the merged region rather than trusting a conflict-free apply — in particular that terminal cell geometry (cell_viewport, hit_test_cell, terminal_run_rect) still uses the monospace advance and is not routed through any new tab-expansion path, since terminal columns come from the child and never from document projection.

Vterm Stage 3 framing lane (superseded)

  • Portable branch: githubsucks/vterm-stage3-framing
  • Revision 8 framing, reviewed and approved. Its content is carried on vterm-gpu; this branch is kept only as the approval record and has no unmerged runtime work.

Parked lane: kill-ring browser + persistence

  • Portable branch: githubsucks/kill-ring-browser
  • Parked framing head: 503c489
  • State: framing only, revision 2; no implementation and no PR.
  • Status: explicitly parked by the user on 2026-07-20.
  • Its original scout was based on 0efb5cd. The preserved framing marks this ground truth stale and requires a complete re-scout against the then-current githubsucks/main before implementation.
  • Compile-mode has merged since the original scout, so old “compile-mode in flight” keybinding/touch-set assumptions are not authoritative.

Recovery worktree, only when the user un-parks it:

git worktree add --track \
  -b kill-ring-browser \
  ../pmacs-kill-ring-browser \
  githubsucks/kill-ring-browser

Documentation lane

  • Portable branch: githubsucks/handoff-2026-07-20
  • Carries synchronized AGENTS.md / CLAUDE.md, this ledger, the durable handoff refresh, and the keybinding reference correction.
  • It changes no runtime code.
  • Review and merge this documentation branch separately; it must not be folded into a feature framing branch.
  • Now also absorbs both landed arcs: Vterm Stage 1 (#126) and the config registry (#127). Canonical main is merged into it up to 2e37c04, so its diff against main is documentation only.

Closed since the last snapshot

  • Config registry — MERGED as #127 (main @ 2e37c04). Its lane (config-registry, worktree ../pmacs-config-registry) is done; the branch is kept but carries nothing unmerged. Durable substrate facts moved to docs/agent-handoff.md §1 per rule 3 below.
  • Both this and Vterm Stage 1 ran as concurrent lanes in sibling worktrees off main, with the shared files (src/editor.rs, src/lua_bindings/mod.rs, src/lib.rs) assigned to one lane each in advance. The rebase of the second lane onto the first had zero conflicts — worth repeating for future parallel work, along with its precondition: agree the file split before either lane starts, and keep each lane's footprint in the other's files to a single line.

Update protocol

Whenever a listed lane changes materially:

  1. update its public branch and head/state here;
  2. record new verification and remove superseded caveats;
  3. keep durable architecture in docs/agent-handoff.md, not here;
  4. remove the lane after merge or abandonment;
  5. verify every recovery command from a clean worktree before calling the transfer complete.
