Check-in [02d993f860]

Lands release step P3-F5-status on trunk, completing the B-status-16 deferral.

The increment: `status` previously classified only `added` and `missing`, so a tracked file that was present but modified produced no line at all — the gap was documented in a comment, in `--help`, and in an e2e test that pinned the silence. Documenting a hole is not the same as not having one, and "your working copy looks clean" is the wrong thing for a version control system to say about an edited file. `status` now resolves the current check-in and compares every tracked file against it, emitting an `edited` row when the bytes or the file mode differ; a file whose contents match is still not listed.

The comparison is not a second implementation. The check-in resolution, the legacy trailing-separator F-card tolerance, the delta-manifest walk, and the merge against the sorted managed set were all machinery `diff` already had; that machinery is extracted into `CheckinBaseline` and `walkWorkingTree`, and both verbs now run through it, with each verb supplying only a sink. `diff` is a pure refactor here — same output, less code. Dirtiness remains a non-failure: every `added`/`edited`/ `missing` row exits 0 (B-status-15); only a genuine comparison failure exits 1. `--help` no longer defers edited-file detection and now narrows the deferral text to the two cases that genuinely remain out of scope.

This lands the full detection called for by P3-F5, not the fallback. The plan's fallback of record required an explicit operator decision; none was taken and none was needed.

Merge evidence: `fossil merge release-0.1` reported no conflicts, updating only src/e2e.zig and src/main.zig. The tree carries no conflict markers — the three open-marker occurrences a grep turns up in src/e2e.zig are string literals inside assertions pinning zit's own merge3 conflict sentinel, not merge residue.

Verification evidence: the merged tree — not merely the branch — was re-verified on trunk after the merge. `zig fmt --check .`, `zig build`, and `zig build test` each exit 0. Behavioral evidence rides in the branch commit's new e2e coverage, which pins each acceptance criterion: an edited tracked file is reported as edited; a rewrite with identical bytes (mtime bump, same content) is not reported; an executable-bit-only change is reported; a file deleted from the check-in but no longer tracked is still not reported; and a delta checkout with an absent B-card baseline fails cleanly rather than reporting a false clean tree. The e2e that pinned the old deferral is replaced by those tests, and the help-text e2es compare against a hand-written expected string, so the `--help` change is pinned too.

`fossil extras` is empty, so the merge adds no file it fails to track.

No performance claim is made here. No borrowed techniques in this change, so no attribution is owed. check-in: 3b7fe2fbe1 user: dmestas tags: trunk

`zit clone` builds a repository file and nothing else. The checkout it left behind was the same UNBORN record `init` writes (`version == ""`, branch `trunk`), with no managed set and no files, and there was no way to turn it into a usable tree: `zit update` accepts only a literal 40/64-hex check-in ID, so a freshly cloned tree could not name its own tip. Clone was a dead end.

`zit open` is the second half of fossil's own clone+open UX. It resolves the tip of the main branch out of this repository's derived state and hands materialization to the SAME `update.applyCheckin` engine every other working-tree move rides — journal-armed, transactional, rollback-safe. Tip resolution is the only work that is open's own; everything else is wiring.

What changed:

- `cli.parseOpenArgs` / `OpenArgs` / `OpenResult`: an operand-free surface. `-h`/`--help` is the only accepted token and wins over every other token; a bare `-x` is an unknown option, anything else an extra argument. The verb takes no operand by design — it derives its target from the repository. - `main.runOpen` plus the `open` entries in the `Verb` enum, the dispatch switch, and the `verb_help` table, so the verb is added in one place and the total switch stays total. `runOpen` writes NO checkout record and NO managed set of its own: `init` already wrote the unborn record, an absent managed set already reads as the empty set, and the update engine stays the single writer of the born record. A second writer of that bootstrap state would only be a second thing to keep in sync. - `main.openApplyFail`: one arm per `update.ApplyError` variant and no `else`, so a new variant fails the compile and forces a decision, mirroring `updateApplyFail`. `SymlinkUnsupported` / `InvalidPath` / `ReservedPath` are raised while planning the TARGET manifest and are reachable on a perfectly intact repository, so they get honest prose instead of a corruption claim. - `update.planUpdate`: an UNBORN record now takes the same arm as an absent one. Unborn is the normal state of every fresh repository, so without this the first `update` after a clone handed `""` to `buildPlan`, failed `artifact.validateName("")`, and reported `CurrentStateInvalid` — a clean, correct tree diagnosed as broken. A record that names no check-in but claims a merge parent or a pending special operation stays incoherent and is still `CurrentStateInvalid`. - BORN-ness, not presence, is the "already open" signal. A presence-based gate would have rejected a clone followed by an open on every clone, the primary path the verb exists to serve.

Test evidence (all run in this worktree after absorbing the sibling P3-F4 commit 281c0ed815, which arrived during this step and was merged by hand in `src/e2e.zig` — both sides had appended the identical P3-F4 block, so the duplicate was dropped):

- `zig build test` — green, including new `update_test.zig` coverage of the unborn-record arm and its incoherent-record rejections. - `zig build e2e` — green, including the P3-F3 block: clone → open → byte-identical tree → update → commit round-trip; a plain clone's unborn checkout tolerated by `update`; an untracked file in the way failing the open and materializing nothing; re-opening an already-open tree refused with no change; a repository with no check-in reported rather than failed; outside a repository failing with the not-a-repo diagnostic (exit 1); unknown option and positional as usage errors (exit 2); and the verb present in top-level help with one help text behind both `--help` and `help open`. - `zig build smoke` — green, with the new S6 scenario (§3.7/§4): `zit clone` + `zit open` against a REAL fossil server materializes the committed bytes byte-for-byte. This is the cross-implementation proof that the new path produces a working tree fossil itself agrees with. - `zig fmt --check .`, `zig build`, and `zig build dst` (6 seeds x 1000 steps) also green.

No borrowed technique in this change. No new file: the work lands entirely in existing modules. check-in: 5ba418801d user: dmestas tags: release-0.1

`zit add DIR` and `zit rm DIR` were hard errors that told the user to name individual files. That made the two most common invocations -- `zit add .` and adding a source subtree -- dead ends, and it was the last place where the CLI asked the user to do work the repository already knows how to do.

What changed:

- `add DIR` now expands to every untracked file beneath the directory. It reuses the ALREADY SHIPPED `extras.sweep` of the checkout root rather than introducing a second walker: the same walk, the same exclusions, the same no-follow symlink posture `addremove` and `clean` use. The sweep is lazy and memoized for the whole invocation, so `zit add a b c` over three directories still performs exactly one enumeration. Because the sweep already subtracts the tracked set and the depth-0 control names, neither can be re-inserted or re-reported by the directory path. - `rm DIR` expands over the TRACKED keys via `ManagedSet.iterate`, never over the disk, so a directory the user has already deleted is still forgettable. Keys are copied into the arena before the first removal, because `iterate()`'s slice and its backing bytes are invalidated by `remove` -- the same discipline `addremove` uses for its remove set. Ascending order is preserved and every expanded key still passes the per-key control-file guard (B-rm-7). - One containment predicate, `pathUnderDir`, serves both verbs, so the boundary case cannot diverge between them: `src2/c` is not under `src`, because containment requires the separator immediately after the directory's bytes. - No new diagnostic class. `zit rm .` with nothing tracked resolves to the existing not-tracked message rather than inventing an empty-expansion error; `zit add .` on a tree holding only control files adds nothing and succeeds. - The `add` and `rm` help text and exit-status wording now describe recursion instead of the removed directory error.

Test evidence: the B-add-5 and B-rm-5 contract tests were rewritten to pin the new behavior (a named symlink is still rejected; a directory now recurses; `.` at the root is never reported as outside the repository), and a new P3-F4 block of end-to-end tests covers nested trees, prefix-boundary siblings, multiple directory arguments sharing one sweep, --dry-run, --hard, and rm of a directory that no longer exists on disk. `zig build test` passes in this worktree after absorbing the sibling packaging commit (3645c03e2d), and the commit is proved against a clean `fossil open` checkout running `zig build` then `zig build test`. check-in: 281c0ed815 user: dmestas tags: release-0.1
