\\ -q, --quiet do not print the added files
\\ -f, --force add a file named directly even when ignore-glob
\\ matches it (a directory expansion always skips those)

\\Rename tracked files: move each working file on disk, swap the
\\tracked-name entries, and record every rename so your next `zit commit`
\\records the new name with the old one as its former name.
\\
\\With two operands and NEW not a directory, OLD becomes NEW. When the last
\\operand is a directory (on disk, or a tracked prefix, or '.'), or there are
\\more than two operands, each OLD moves into it keeping its base name. An
\\OLD that is a tracked directory moves as a unit, every file beneath it
\\recorded as its own rename.
\\
\\Every OLD must be tracked and present; no NEW may already be tracked or
\\exist on disk. The whole request is checked before anything moves, and
\\nothing overwrites. mv is not undone by `zit undo`; to reverse a rename,
\\run `zit mv NEW OLD`.
\\
\\options:
\\ -n, --dry-run print 'would rename OLD -> NEW' per file; change nothing
\\ --soft record the renames without touching the working tree (the
\\ files stay at OLD; status then shows NEW missing until
\\ you move them)
\\ --hard move the files too (the default)
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 the files were renamed
\\ 1 an OLD is not tracked or missing, a NEW is already tracked or on
\\ disk, or this is not a zit repository
\\ 2 usage error (fewer than two operands, or an unknown option)

const merge_help_expected =
\\usage: zit merge [-X ours|theirs] [--no-sync] [--no-precedent]
\\ [--baseline B] [--integrate] [NAME]
\\ zit merge --probe|-n|--dry-run NAME... [--into TARGET]
\\ zit merge --cherrypick NAME
\\ zit merge --backout NAME
\\
\\Merge the check-in NAME into the working tree with a three-way merge and
\\record it as a pending merge parent. NAME resolves like 'zit info' — a full
\\or abbreviated artifact ID, a branch, or a tag; with no NAME, the one
\\other open leaf is merged (several is an error naming them). This does
\\not create a check-in; run 'zit commit' to record the merge. Conflicts are written into
\\the working files with conflict markers and listed on stderr — resolve them
\\and commit, or run 'zit undo' to abandon the merge.
\\
\\Uncommitted work does not block the merge: your working file is the merge's
\\own "current" side, so a region only you changed stays yours and a region
\\only NAME changed is applied around it. Where the two collide you get
\\markers, the same as any other conflict, and 'zit undo' restores the
\\uncommitted bytes.
\\
\\-X resolves every CONTENT conflict in favour of one side instead of writing
\\markers: 'ours' keeps the working tree's version wherever the two sides
\\disagree, 'theirs' takes NAME's. Regions only one side changed are still
\\that side's either way -- -X answers only what the merge could not, so it
\\is not "discard their work", it is "stop asking me". The mechanical cases
\\are what it is for: a regenerated lockfile, a vendored tree taken whole
\\from upstream.
\\
\\--probe answers "would this merge cleanly?" and writes NOTHING -- no merge,
\\no working tree touched, no autosync. It prints one line, `merges` followed
\\by clean, up-to-date, unrelated, or conflict (N), and then one
\\`conflict PATH` line per unresolvable path. Exit status is 0 in every one
\\of those cases: "has conflicts" is an answer, not a failure, so a caller
\\reads the line rather than the status.
\\
\\Given several NAMEs, --probe answers a STACK: each NAME against TARGET
\\with the NAMEs before it already landed, in memory, in order. One line
\\per NAME -- `merges NAME` and its verdict -- with `conflict PATH` lines
\\under the one that stops, and `not-reached` for every NAME after it: a
\\merge that did not complete leaves nothing to continue from. This is
\\not the same as probing each NAME against the one below it: that says
\\nothing about what TARGET changed meanwhile, so it can call a rung
\\clean that stops the landing.
\\
\\Being a read, --probe takes -R and needs no checkout -- but then there is
\\no current check-in to merge into, so --into TARGET is required. In a
\\checkout it defaults to the check-in you are on, exactly as a real merge
\\takes its other side. A real merge refuses -R: it writes a working tree.
\\
\\-X ours IS NOT --backout. --backout reverses NAME's change; -X ours keeps
\\your side where the two collide and reverses nothing. They read alike and
\\do different things, which is the misread worth avoiding.
\\
\\One case -X deliberately does not answer: a file one side modified and the
\\other deleted. That is a disagreement about whether the file should exist,
\\not about its contents, and either reading silently destroys work -- so it
\\stays a conflict for you to settle, with or without -X.
\\
\\--cherrypick and --backout are special merges that pick an alternate
\\baseline instead of the common ancestor: --cherrypick applies only NAME's
\\own change onto the working tree, --backout reverses it. 'zit commit' then
\\records the operation as a cherry-pick/backout, not as a merge parent.
\\
\\options:
\\ -h, --help show this help and exit
\\ -X, --strategy ours|theirs
\\ resolve content conflicts in favour of one side
\\ --no-sync skip the autosync pull for this invocation
\\ --no-precedent do not replay remembered conflict resolutions for
\\ this merge (see 'zit precedent'); nothing is
\\ forgotten, only declined
\\ --cherrypick NAME apply only NAME's own change onto the working tree
\\ --backout NAME reverse NAME's change on the working tree
\\ -n, --dry-run the same as --probe
\\ --baseline B use check-in B as the common ancestor instead of
\\ the computed merge base
\\ --integrate close NAME's leaf when this merge is committed
\\
\\exit status:
\\ 0 success
\\ 1 operational failure (not a repository, unreadable state, a refused
\\ action) — the diagnostic on stderr names it
\\ 2 usage error (an unknown option or unexpected argument)

\\Show the state of the working copy: the current branch, the current
\\check-in (if any), and the state of your tracked files.
\\
\\Under a pending merge, an edited file that still carries conflict
\\markers is reported as CONFLICT. Rows use Fossil's words (ADDED,
\\EDITED, MISSING, CONFLICT, EXTRA, MERGED_WITH) in an aligned column;
\\--classify is accepted and changes nothing. The kind flags narrow the
\\rows to those kinds; --differ is
\\--edited plus --extra, and --extra lists the untracked files 'zit
\\extras' would (names beginning with a dot only under --dotfiles).
\\The report leads with Fossil's checkout block —
\\repository, local-root, checkout, parent, tags, comment — with
\\twelve-character names and the weekday in the times; 'zit changes'
\\is the same report without the block, as in Fossil.
\\
\\zit has no staging area. `status` reports the files you marked with
\\`zit add` and how each one stands in the working tree:
\\
\\ ADDED <path> tracked and new — it will enter your next check-in
\\ EDITED <path> tracked, and its bytes or mode differ from the check-in
\\ MISSING <path> tracked, but not present in the working tree
\\
\\A tracked file whose contents match the current check-in is not listed.
\\
\\Until your first `zit commit` the branch 'trunk' is unborn: there is no
\\check-in yet, so every tracked file is reported as ADDED (it will form
\\the root check-in). The current check-in, once one exists, is shown as its
\\full artifact hash.
\\
\\Two things `status` does not report, because it walks only your tracked
\\files: a file deleted from the check-in but no longer tracked (`zit diff`
\\lists it) and untracked "extra" files (`zit extras` lists them).
\\
\\options:
\\ -v, --verbose accepted; the block is printed either way
\\ --classify accepted; Fossil's words are the default
\\ --added, --edited, --missing, --conflict, --extra
\\ only rows of those kinds
\\ --differ --edited plus --extra
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 the working-copy state was reported (with or without changes)
\\ 1 this is not a zit repository, or its state could not be read
\\ 2 usage error (an unknown option or an unexpected argument)

\\usage: zit commit [-m <message> | -M <file> | --editor <prog>] [-n|--dry-run]
\\ [--allow-empty] [--user <login>] [--branch <name>] [--close]
\\ [--allow-fork] [--no-sync] [--sign] [-q|--quiet]
\\ [--no-checks|--no-warnings] [--no-submanifest-advice]
\\ [--] [<path>...]
\\
\\Record a check-in: save the current contents of your tracked files as a
\\new, permanent point in history on the current branch.
\\
\\zit has no staging area. `commit` reads each tracked file straight from
\\the working tree right now — there is nothing to stage first. With no
\\paths, every tracked file is captured; name one or more paths to commit
\\just those (the rest of the tree is carried forward unchanged).
\\
\\The first commit in a new repository creates the root check-in and starts
\\the default branch 'trunk'. Each check-in is named by its full artifact
\\hash (SHA3-256).
\\
\\--branch <name> starts a new branch at this check-in: the check-in moves
\\onto <name> and later commits inherit it. <name> must not already name an
\\open branch, and there must be a parent to fork from. --close marks this
\\check-in a closed leaf, so it no longer shows as an open head of its branch.
\\
\\History is immutable: a check-in is never rewritten. There is no amend and
\\no --force; to undo a file, change it and commit again. To stop tracking a
\\file (and record its deletion), use `zit rm` then commit.
\\
\\The comment comes from -m, from -M <file>, or from an editor: with no
\\-m on a terminal, commit opens $VISUAL (else $EDITOR, else --editor
\\<prog>) on a template whose '#' lines name the branch, the parent and
\\every file this commit captures; those lines are stripped, and an
\\empty comment aborts. The template lives in .zit-ci-comment in the
\\checkout root and stays there when the commit fails after the editor,
\\so 'commit -M .zit-ci-comment' retries without retyping. Off a
\\terminal, a missing -m is still a usage error. -n reports what would
\\be recorded and writes nothing. Only regular files are captured.
\\
\\On a repository with sub-manifests enabled and pinned, a commit that
\\drifts far enough from the analyzed optimum (draft-fossil-submanifests-00
\\§6.4) prints one advisory line and, interactively, offers to retune.
\\"Far enough" is zit's §6.4 relative margin m: a re-tune is advised only
\\when it would improve the analyzed read cost by more than 15% of the
\\pinned value's own cost. --no-submanifest-advice suppresses the advisory
\\entirely. Never affects whether the commit itself succeeds.
\\
\\options:
\\ -m, --message <message> the check-in comment
\\ -M, --message-file <file> read the comment from <file>
\\ --editor <prog> compose the comment in <prog> (default:
\\ $VISUAL, then $EDITOR, on a terminal)
\\ -n, --dry-run list what would be recorded; write nothing
\\ --allow-empty record a check-in with no file changes
\\ --user <login> author to record (default: $USER)
\\ --branch <name> start a new branch at this check-in
\\ --close mark this check-in a closed leaf
\\ --allow-fork commit even though the current check-in is no
\\ longer the tip of its branch — a deliberate
\\ fork (refused otherwise, naming the newer tip)
\\ --no-sync skip autosync (the pull before and push
\\ after) for this one commit
\\ --no-checks waive the binary-glob/crlf-glob/encoding-glob
\\ content gate for this one commit
\\ (--no-warnings is Fossil's spelling of the
\\ same waiver)
\\ --sign clearsign the manifest before storing it.
\\ The signed text IS the stored artifact, so
\\ every reader strips the wrapper to reach
\\ the cards and the signature travels with
\\ the check-in wherever it syncs.
\\ The signer is $ZIT_PGP_COMMAND, fossil's
\\ pgp-command contract: default
\\ 'gpg --clearsign -o ', invoked as
\\ COMMAND OUTFILE INFILE; a command whose
\\ basename starts with 'ssh' is invoked as
\\ COMMAND INFILE, writes INFILE.sig, and its
\\ armor is assembled here. 'off' disables
\\ signing. Refused — never committed
\\ unsigned — if the signer fails or alters
\\ the manifest it was given.
\\ -q, --quiet do not print the check-in line
\\ --no-submanifest-advice
\\ suppress the sub-manifest drift advisory
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 the check-in was created
\\ 1 nothing to commit, a tracked file is missing, an empty message, an
\\ existing branch name, or this is not a zit repository
\\ 2 usage error (no message, or an unknown option)

\\P-card order. CHECKIN accepts every form 'zit help names' lists —
\\IDs, prefixes, branches, tags, reserved forms, and timestamps. Each
\\check-in is shown once; a referenced parent missing from this
\\repository is shown once as a phantom.
\\
\\With PATH, show only the reachable check-ins that change PATH — where
\\PATH's effective content differs from its primary parent's, including
\\where PATH is added or deleted. PATH is an exact repo-relative path, not
\\a pattern; a path that never changed yields no output.
\\
\\--long adds each check-in's own facts after its id:
\\
\\ checkin <id> <timestamp> <user> <comment>
\\
\\The comment is last because it is the only field that may contain
\\spaces; a check-in with no comment prints an empty trailing field, so
\\the column count never varies. Absent timestamp or user read '-'.
\\
\\This record grammar is a contract: consumers parse it positionally, and
\\no display option, present or future, will change it. Presentation
\\extras (the timeline's --weekday, for one) belong to the verbs whose
\\output is for eyes, not parsers.
\\
\\options:
\\ --long add timestamp, user and comment to each entry
\\ -n, --limit N show only the N most recent entries; 0 means all
\\ -R, --repo <path>
\\ read this repository instead of the one found from the
\\ current directory; <path> is the directory holding '.zit'
\\ (or the '.zit' file itself). No working tree is required.
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 success
\\ 1 operational failure (not a repository, unreadable state, a refused
\\ action) — the diagnostic on stderr names it
\\ 2 usage error (an unknown option or unexpected argument)

\\`(N) time [hash] comment (user: … tags: …)`, with the weekday and a

\\ --all also list closed leaves, tagged "closed"
\\ --no-cache bypass every derived sidecar (the cache AND the rebuild
\\ checkpoint) and re-derive from the full log, re-verifying
\\ whole-log integrity (the cache is refreshed)
\\ -R, --repo <path>
\\ read this repository instead of the one found from the
\\ current directory; <path> is the directory holding '.zit'
\\ (or the '.zit' file itself). No working tree is required.
\\ -h, --help show this help and exit

\\
\\List every check-in in the repository, most recent first. Each line shows
\\the check-in's short hash, its ISO timestamp, its branch, and the first
\\line of its comment. A check-in that joins two or more lines of development
\\is marked "M". Order is by event time descending, ties broken by artifact
\\hash, so the listing is byte-identical across runs.
\\
\\Filters narrow the listing: -b BRANCH to one branch, -c to the checkout's
\\branch, -p PATH to the check-ins that change PATH against their primary
\\parent, -u LOGIN to one author. -r lists oldest first; --offset N skips
\\the first N matches before -n counts. The default (-F medium) is
\\Fossil's shape — a date header once per day, with the weekday, then
\\time, a twelve-character hash, *CURRENT* on the checkout's check-in,
\\the comment, and (user: … tags: …); -F oneline is one line per
\\check-in (hash, ISO time, branch, comment) for scripts; -F full adds
\\each check-in's changed files, which -v adds to any format.
\\
\\--weekday prints each check-in's day of week between the hash and the
\\date. Days are UTC, like every timestamp here, so a late Friday commit
\\in your local zone can read Saturday. The computation is Ben Joffe's
\\branchless day-of-week (benjoffe.com/fast-day-of-week).
\\
\\options:
\\ -n, --limit N show only the N most recent entries; 0 means all
\\ --offset N skip the first N matching entries
\\ -b, --branch B only check-ins on branch B
\\ -c, --current-branch only check-ins on the checkout's branch
\\ -p, --path P only check-ins that change P
\\ -u, --for-user U only check-ins by U
\\ -r, --reverse oldest first
\\ -v, --verbose list each check-in's changed files
\\ -F, --format F oneline (default), medium, or full;
\\ --oneline/--medium/--full are the same
\\ --weekday show the UTC day of week beside each date

\\A tag is one of two things, and --raw is what picks between them.

\\
\\With --raw, NAME is written verbatim as a PROPERTY, outside name
\\resolution entirely. Use it for a fact many check-ins may carry — a CI
\\verdict, a review marker — optionally with a VALUE. Because raw tags are
\\not names, plain list does not show them; list --raw does.
\\
\\cancel retracts a tag from a check-in. It takes the same --raw choice as

\\usage: zit info [NAME...] [-F text|json] [--no-cache]
\\
\\With no NAME, describe the check-in the working tree is on (Fossil's
\\bare 'info'); NAME is any check-in name.
\\
\\Resolve each NAME to a single check-in and describe it. NAME may be a
\\full 40- or 64-character artifact ID, a unique ID prefix, a branch or
\\tag name, a reserved form, or a timestamp — 'zit help names' states the
\\full procedure. Resolution follows recency, not open-leaf status: a
\\name can resolve to a closed or non-leaf check-in that 'zit leaves'
\\would not list.
\\
\\Several NAMEs share one repository open; their blocks are separated by
\\a blank line. A NAME of '-' reads names from stdin, one per line. A
\\name that does not resolve is reported and the rest are still
\\described; the exit status is then 1.
\\
\\options:
\\ -F, --format <f>
\\ text (default): the block above per check-in.
\\ json: one object per NAME, in the order given, with the
\\ keys name, hash, branch, leaf, parent (null for a root),
\\ merge, cherrypick, backout (arrays), and comment, user,
\\ date when an amend override is active; a name that does
\\ not resolve is {"name":..., "error":...}.
\\ --no-cache bypass every derived sidecar (the cache AND the rebuild
\\ checkpoint) and re-derive from the full log, re-verifying
\\ whole-log integrity (the cache is refreshed)
\\ -R, --repo <path>
\\ read this repository instead of the one found from the
\\ current directory; <path> is the directory holding '.zit'
\\ (or the '.zit' file itself). No working tree is required.
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 success
\\ 1 operational failure (not a repository, unreadable state, a refused
\\ action) — the diagnostic on stderr names it
\\ 2 usage error (an unknown option or unexpected argument)
\\

\\usage: zit artifact HASH [--raw]
\\
\\Describe or dump a single stored artifact addressed by its hash. HASH is a full
\\or abbreviated (>=4 character) lowercase hexadecimal artifact ID, resolved
\\against every stored artifact — file blobs included. Branch and tag names are
\\not accepted; use 'zit info' for those.
\\
\\Without --raw, print a summary: the full hash, the artifact's size, its type,
\\and — for a structural artifact — one line per card and whether its Z
\\self-checksum verifies. A blob reports its size and whether it is binary.
\\
\\With --raw, write the artifact's exact stored bytes to standard output,
\\verbatim — no trailing newline is added and binary content passes through
\\unchanged. Hashing those bytes reproduces HASH.
\\
\\options:
\\ --raw write the exact stored bytes instead of a summary
\\ -R, --repo <path>
\\ read this repository instead of the one found from the
\\ current directory; <path> is the directory holding '.zit'
\\ (or the '.zit' file itself). No working tree is required.
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 success
\\ 1 operational failure (not a repository, unreadable state, a refused
\\ action) — the diagnostic on stderr names it
\\ 2 usage error (an unknown option or unexpected argument)

\\Show, for each line of PATH, the check-in that introduced that line and
\\when. PATH is an exact repo-relative path to a tracked file; each output
\\line is the introducing check-in's 12-character artifact-ID prefix, the
\\ISO date it was recorded (UTC), then the file line.
\\
\\VERSION selects the annotated check-in the same way 'zit info' does; with
\\it omitted, the current checkout is annotated. With -R and a VERSION no
\\working tree is required.
\\
\\Provenance is computed over the file's whole version history: a line is
\\attributed to the oldest check-in that carries it. A line that arrived from
\\a merged branch is credited to its origin on that branch, never to the merge
\\check-in itself. Only committed content is annotated — uncommitted edits in
\\the working file are not shown.
\\
\\options:
\\ -n, --limit N look back at most N check-ins; a line older than the
\\ window is credited to the oldest check-in shown
\\ -l, --log list the check-ins consulted (newest first) before
\\ the lines, separated by a '---' line
\\ --full emit the full artifact ID per line instead of the
\\ 10-character prefix (stable as an index key)
\\ -R, --repo <path>
\\ read this repository instead of the one found from the
\\ current directory; <path> is the directory holding '.zit'
\\ (or the '.zit' file itself). No working tree is required.
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 the annotation was written
\\ 1 PATH is not tracked at the annotated check-in, its content is
\\ binary, VERSION does not resolve, or this is not a zit repository
\\ 2 usage error (a missing PATH, an unknown option, or a third positional)

// --- open: clone → working tree (P3-F3) ------------------------------------
//
// `zit clone` builds a repository file and nothing else: the checkout it leaves
// behind is the same UNBORN record `init` writes (`version == ""`, branch
// `trunk`), with no managed set and no files. `zit open` is the second half of
// fossil's own `clone` + `open` UX — it resolves the tip of the main branch and
// materializes it through the shared update engine.
//
// The proof chain below is the missing end-to-end the pre-release assessment
// called out: the existing clone e2e asserts artifact-digest-set equality only,
// which proves the wire converged but says nothing about whether a cloned repo
// can become a usable working tree.
const open_help_expected =
\\usage: zit open [CHECKIN | URL] [--store=PATH] [--manifest[=r,u,t]]
\\ [--cone=PATH] [--cone-not=PATH] [--cone-file=FILE]
\\ [-h|--help]
\\
\\Materialize a check-in in the working tree of a not-yet-open checkout.
\\Given a URL instead, this is 'zit clone URL': the repository is cloned
\\into a directory named from the URL and opened there.
\\This is the second half of 'zit clone URL DIR': clone builds DIR and its
\\'.zit', open fills DIR with the files of a check-in. Run it from inside
\\the checkout directory.
\\
\\Without CHECKIN, the tip of this repository's main branch is opened.
\\CHECKIN accepts every form 'zit help names' lists — IDs, prefixes,
\\branches, tags, reserved forms, and timestamps — so a fresh clone can
\\open straight at a release tag without materializing the tip first.
\\
\\A working tree that is already open at a check-in is left untouched; use
\\'zit update' to move an open tree to a different check-in. A repository
\\with no check-in yet is already in its correct (empty) state, which open
\\reports and leaves alone — though a CHECKIN named explicitly must
\\resolve, so in an empty repository it fails as not found.
\\
\\--manifest asks this checkout for the files some build systems read to
\\stamp a version into their output: 'manifest' (the check-in artifact, r),
\\'manifest.uuid' (its hash, u) and 'manifest.tags' (its symbolic tags, t).
\\The bare flag or 'on' means 'ru'; 'off' writes none, whatever the
\\project's 'manifest' setting says. The choice is remembered, so every
\\later 'zit update' rewrites the files for the check-in it moves to.
\\Without the flag the project's 'manifest' setting decides, and a file of
\\one of those names that the check-in itself tracks is never replaced.
\\
\\--store=PATH opens a second working tree of an EXISTING repository: run
\\it in an empty directory and name the checkout (or the '.zit' file) that
\\holds the store. The new tree keeps its own checkout state but reads and
\\writes the one shared store, so a commit in either tree is visible to
\\the other immediately; concurrent commits serialize on the store's own
\\lock. The directory must not already be a checkout.
\\
\\--store on a tree that is ALREADY open re-points it instead: after the
\\repository moves, run open --store=NEWPATH in the stranded tree and it
\\resumes where it was, uncommitted work intact. The new PATH must hold
\\the same repository -- one containing this tree's current check-in --
\\so a tree cannot be re-pointed at an unrelated store.
\\
\\options:
\\ --store=PATH create a detached working tree of the repository
\\ at PATH before opening
\\ --manifest[=r,u,t] write manifest, manifest.uuid, manifest.tags
\\ --cone=PATH materialize and track only PATH's subtree
\\ (repeatable) — a sparse checkout from the start
\\ --cone-not=PATH exclude PATH's subtree from an enclosing --cone
\\ member (repeatable); the most specific member
\\ decides coverage
\\ --cone-file=FILE read cone members from FILE, one per line
\\ ('#' comments and blank lines are skipped;
\\ a '!' prefix marks an exclusion)
\\ -h, --help show this help and exit
\\
\\exit status:
\\ 0 success
\\ 1 operational failure (not a repository, unreadable state, a refused
\\ action) — the diagnostic on stderr names it
\\ 2 usage error (an unknown option or unexpected argument)
\\

// A merge whose only change is an ADDED file is silently lost (blocker B5,

// the working tree but never inserts it into `.zit-managed`, so the file is
// simultaneously present on disk and untracked: `status` reports "nothing to
// report", `extras` lists the merged file as junk, and `commit` refuses with
// "nothing to commit (no changes)" — dropping the merge parent that `merge`
// recorded in `.zit-checkout`. The user's only escape is `undo`.
//
// The symmetric half of the same omission: a merge that DELETES a file leaves
// the path managed, so `status` reports a phantom "missing" and `commit`
// refuses with "cannot commit … missing from the working tree". Both ride the
// same `applyMerge` entry stream, so both are encoded here.
//
// ORDERING: the defect is a managed-set mutation, so each repro is built in
// both orderings that could hide it — the merge direction (feature→trunk and
// trunk→feature) and the added path's position in the sorted managed set
// (`feat.txt` inserts AFTER `base.txt`; `aaa.txt` inserts BEFORE it). Identical

/// branch whose ONLY change is an added `feat.txt`. Leaves the checkout back on

// line 27 / line 132: "tag | PARTIAL | read-only — `tag list` only, no
// create"). The fix mints a CONTROL artifact carrying `T +sym-NAME <hash>` —
// a SINGLETON (`+`), not a propagating (`*`) tag: repostate's `resolveName`
// (src/repostate.zig:891) picks the max-event.mtime check-in among ALL active
// sym rows, so a propagating sym would be inherited by every descendant and
// silently resolve to the newest one — a B1-class wrong answer. `applyTagOps`
// (src/repostate.zig:727) gates propagation on `op.type != .singleton`, so a
// singleton card flows through the existing machinery unchanged.
//
// Plan §4 requires a ROUND TRIP, not just local visibility: create, see it in

\\from the frames in `.zit` — nothing is estimated, and nothing is derived
\\from the file's size.
\\
\\Output is one 'field value' line per fact, so it reads by machine:
\\
\\ project-code this repository's shared sync identity, the
\\ value a peer matches on and the first input to
\\ an authenticated push's derived secret. Empty on
\\ a repository that predates project codes.
\\ hash-policy which names this repository mints
\\ store-bytes the `.zit` file itself, in bytes
\\ header-bytes the store header
\\ content-bytes artifact payload bytes, summed frame by frame
\\ frame-overhead-bytes frame headers and 8-byte padding for those frames
\\ config-bytes the repository's config record
\\ shun-bytes the repository's shun table
\\ shun-rows rows in that table
\\ user-bytes the repository's user table
\\ user-frames frames in that table -- rows plus any
\\ supersede markers a pack has not yet reclaimed,
\\ so this can exceed what `zit users` prints
\\ artifacts stored artifacts (the config record is not one)
\\ full-form artifacts stored whole
\\ full-form-bytes content-bytes held by those artifacts
\\ deltas artifacts stored against a base
\\ delta-bytes content-bytes held by those artifacts
\\
\\-R names a repository with no working tree, so a bare store answers all
\\of the above without a checkout, a port, or a child process.
\\
\\content-bytes and store-bytes are different measurements and must not be
\\substituted for one another: the store also carries the header, a header
\\per frame, and padding, so it is always the larger number. The five byte
\\fields plus header-bytes account for the file exactly.
\\
\\full-form-bytes and delta-bytes PARTITION content-bytes; they are not
\\further components of the file and must not be added to the accounting
\\above. Read them against full-form/deltas rather than instead of them: a
\\store is routinely a minority full-form by artifact and a large majority
\\full-form by byte, because an artifact is stored whole exactly when
\\delta did not pay -- the large, poorly-compressible ones.
\\
\\options:
\\ -h, --help show this help and exit
\\ --artifacts list the stored artifact hashes instead, one per line,
\\ in ascending hash order
\\ --type=KIND with --artifacts, list only 'full' or 'delta' artifacts
\\
\\exit status:
\\ 0 the report was written
\\ 1 this is not a zit repository, or `.zit` could not be read
\\ 2 usage error (an unknown option, a repeated --type, a --type without
\\ --artifacts, or an unexpected argument)
