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 @ 86fc1bc (Vterm Stage 2 #130 merged; 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 86fc1bc or a newer intentional main. If it does not, stop and repair the remote/fetch configuration.

Modeline detection implementation lane

• Portable branch: githubsucks/modeline-detection
• Approved framing head: 6b4f3c3
• Implementation head: f8d05d2
• Base: originally canonical main @ d5d9b9c; current canonical main @ 86fc1bc (Vterm Stage 2 #130) is integrated before merge.
• PR: #132, https://github.com/levineuwirth/pmacs/pull/132, open against canonical main and explicitly authorized for merge.
• State: Revision 2's bounded Emacs/Vim parser, explicit-over-inferred precedence, alias normalization, shared fresh-load language pin, LSP path guard, and all thirteen acceptance criteria are implemented. Protocol remains v18.
• Verification:
  • focused modeline + shebang-pin acceptance before integration: 7 passed on default LuaJIT and 7 passed on non-default Lua 5.4;
  • post-integration cargo fmt --check;
  • post-integration cargo clippy --workspace --all-targets -- -D warnings;
  • post-integration cargo test --lib: 1,753 passed;
  • post-integration cargo test --lib --features crdt: 1,929 passed;
  • post-integration cargo test --test m4_acceptance -- --skip basedpyright: 120 passed, 3 ignored, 1 filtered;
  • post-integration PMACS_REQUIRE_GPU=1 cargo test -p pmacs-gpu: 109 passed;
  • post-integration cargo test --workspace -- --skip basedpyright: 2,888 passed across 82 suites, 19 ignored, 1 filtered;
  • git diff --check.
• Next: push the current-main integration and merge PR #132 as authorized.

Recovery worktree on a machine that does not already own the branch:

git worktree add --track \
  -b modeline-detection \
  ../pmacs-modeline-detection \
  githubsucks/modeline-detection

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.
