fix(git): fix the ratchet's quoting bug in-process, and decide the rest of the module stays shelled out

[wenzowski]

Three commits: one live bug fixed, one latent inconsistency closed, and the
decision that stops the rest of git.rs being migrated for its own sake.

The live bug — count_at_rev (CLOUD-749)

count_at_rev read ls-tree through plain query, so path quoting was
whatever the host's git config said. Under git's default core.quotePath=true
a non-ASCII path arrives as "caf\303\251.rs" — literal quotes, octal escapes —
and the glob silently fails to match it. The working-tree half walks with
ignore and sees the real path, so the two halves selected different files.

Reproduced before fixing: deleting a #[test] inside src/café.rs produced
empty stdout and exit 0. The ratchet reported clean while a test was
deleted — a gate that could not fail. A second case shows the verdict moving
with core.quotePath, so two developers got different answers for the same
commit.

This is CLOUD-328's failure class on a second axis, in the same function
CLOUD-328 already fixed for gitlinks. Now read in-process: gix's traversal
recorder returns the path as bytes and the mode as a typed value, so quoting
cannot reach the answer and the gitlink skip is mode.is_commit() rather than a
string compared against 160000. GITLINK_MODE goes with it.

The latent one — resolve_ref

It interpolated name into rev-parse --verify --quiet <name> with no
--end-of-options, while head_commit three functions above carries the token
with the same --verify. name reaches it from config (must_land_on), which
a branch can edit absent --config-from.

Severity from measurement, not assumption: latent, not live. An
option-shaped name is parsed as an option — --local-env-vars printed
environment variable names — but --verify exits non-zero for anything that is
not a single rev, and query_optional reads non-zero as None, so the caller
already got the safe answer. rev-parse also has no file-writing option, so
there is no show-shaped write (CLOUD-718). One line, not a rewrite.

The decision — why the rest of the module stays shelled out

git.rs's module doc and mem:core now record the split, so it reads as a
decision rather than an abandoned migration. The bar: in-process only where a
library makes a defect unrepresentable.

The other eleven functions in CLOUD-738's scope were audited individually and
none clears it — current_branch/upstream_of_head sit in rev-parse's
ref-PRINTING modes with no caller token; head_commit/log_messages already
carry the token; refs, common_dir, is_shallow, root_commits, remotes
take fixed argv and read formats that cannot carry a separator.

The latency argument was measured and does not carry a rewrite. key_facts
is the only site on the mediated-call path and it is conditional —
policy.key_base_for(&envelope).and_then(key_facts) fires only on the two
requires_key shapes. Hyperfine, 100 runs, release binary:

hook path	mean
gh pr merge (no key_facts)	4.7 ms
gh pr create (key_facts runs)	11.4 ms

6.7ms of a 100ms budget, on a handful of calls per session.

landing/patch identity stays because its two admitted defects are inert:
a PatchId is only ever compared against one from the same binary in the same
run, so the zlib instability cannot bite, and the whitespace collision biases
toward the safe answer by design. worktrees/stash_create stay because git
is the authority — gix 0.86 has no prunable concept and no stash API at all
(measured), and re-deriving either would make Batten a second answer to a
question git owns, which is CLOUD-46's deferral and the "adopt prior art; don't
expand the core" rule.

CLOUD-738, CLOUD-739 and CLOUD-740 are Canceled on these grounds, each with
its measurement on the issue.

Also

release-artifacts.yml's 10x macOS-runner note now reads as a private-repo
price rather than a capability limit, since public repos are unmetered —
the correction CLOUD-737's actionable half asked for.

On the tests

Every case was shown red against the previous code first. That ordering is the
point CLOUD-749 makes and this branch owes: "existing tests unchanged and green"
would not have caught the quoting bug, and a migration reproducing it in gix
form would have passed.

The resolve_ref case is honest about what it pins — it passes without the
token (verified), and goes red when query_optional's non-zero-is-None
reading is removed (verified). Its comment says so, because a case claiming to
test the token while being blind to it is the false green this work has already
hit twice.

CLOUD-749 `count_at_rev` reads `ls-tree` under the host's `core.quotePath`, so a non-ASCII path undercounts the ratchet's base side

A live wrong answer, not a smell. Filing rather than leaving it as a note on CLOUD-738: that slice is Backlog and unscheduled, and this ships an incorrect ratchet verdict today.

The defect

DIFF_CONFIG pins core.quotePath=true (git.rs:125) but is applied at exactly one call site — patch_ids (git.rs:1331). count_at_rev (git.rs:1182) calls plain query, so path quoting is whatever the host's git config says.

With quoting on — git's default — a non-ASCII path arrives from ls-tree as "caf\303\251.rs": literal double quotes, octal escapes. selector.matches(path) (crate::rules::Selector, CLOUD-214) then silently fails to match it.

The ratchet's base side undercounts. Its worktree side counts correctly, because that half walks the tree with ignore and gets real OsStr paths. So the two sides answer differently for the same glob:

• A repository whose glob spans any non-ASCII path reports an improvement nobody made — the base looks larger than it is only if the count went the other way, and looks smaller when the path was there all along, so the direction of the error depends on which side the path sits. Either way the delta is fiction.
• Two hosts get different numbers for the same commit, because core.quotePath=false is a legal local setting.

This is CLOUD-328's failure class on a second axis — a ratchet that counts one side differently from the other, producing a gate that cannot fail. CLOUD-738 already cites CLOUD-328 for the gitlink half of this same function (GITLINK_MODE, the submodule case where a glob counted 637 one side and 1404 the other). Same function, same shape, different axis, unnoticed.

Fix

-z on the ls-tree read, which sidesteps quoting entirely — matching changed_paths' already-correct treatment at git.rs:954, which is the shape the rest of the module treats as the model (NUL-delimited, non-UTF-8 paths dropped rather than lossily converted). Pinning core.quotePath=false via -c would also work but adds a 27th pinned setting to a module CLOUD-739 is trying to get out of the config-pinning business.

Relationship to CLOUD-738

That slice has count_at_rev in scope and its in-process rewrite would incidentally remove this. Two reasons not to wait:

1. It is Backlog and unscheduled; the wrong answer ships meanwhile.
2. CLOUD-738's acceptance is "existing tests unchanged and green", which would not catch this either way. A migration that silently reproduced the bug in a new form would pass. The test is the durable artefact here, not the patch.

So: land the test first, watch it fail on main, then the -z patch. CLOUD-738 later deletes the patch and inherits the test — which is the right division, because the test is what proves the migration fixed something rather than moving it.

Acceptance

• A ratchet fixture with a non-ASCII path inside the glob, asserting the base and worktree counts agree. Must be shown to fail on main before the fix lands, or there is no evidence it measures anything.
• A second case with core.quotePath set both ways in the fixture repo's own .git/config, asserting the answer does not move — the property that makes the count host-independent.
• Existing count_at_rev tests green, including CLOUD-328's submodule/gitlink case.

Found while auditing the crate's subprocess and string-boundary sites.

CLOUD-320 Inventory the engine's shell-outs and decide which should be in-process

Why now. CLOUD-90 added a third class of shell-out — curl for the
https:// provision fetch — and it was added because measurement forced it,
not because it was the design anyone wanted. That is one shell-out too many to
keep carrying without a written position, so this issue is the inventory and the
decision, before a fourth arrives by the same route.

The measurement that produced the newest one (CLOUD-90, 2026-08-11). No
TLS-capable Rust HTTP client can be linked into this crate:

Candidate	Why it fails macos-link-check
reqwest + default-tls (native-tls)	native-tls, openssl-sys — named framework crates
reqwest + rustls-tls-native-roots	pulls security-framework, security-framework-sys
reqwest + rustls-tls-webpki-roots	ring declares a links key (gate rule 1)

The gate exists because the macOS release artifacts are linked on Linux by zig
with no Apple SDK, and it is deliberate. So curl is not a shortcut around a
constraint — it is the only path that satisfies both the constraint and the
acceptance's proxy-CA property, and arguably satisfies the latter better than a
library would, since it is the host's actual TLS stack rather than a
re-implementation of one. House style §9 says the same thing from the other
direction: name a command already on the operator's PATH.

The inventory. Not every shell-out is debt, and conflating them is how the
real one hides:

• By design, not debt. exec.rs (batten exec -- …) and rules.rs's
  command kind run a command the caller named. That is the feature; there is
  nothing to move in-process.
• Debt, load-bearing. git.rs — every git fact is a spawned git with its
  output parsed. It is disciplined (one invoker, gated by
  no_second_git_invoker_exists, environment scrubbed, fixed argv), and it works,
  but it is text-parsing a CLI whose output is version-dependent prose. CLOUD-51
  measured a real instance: rev-parse in ref-printing mode does not consume
  --end-of-options, it echoes it as an output line, so the house pattern
  silently produced "--end-of-options\nrefs/remotes/origin/main" as a resolved
  ref. A library would have made that unrepresentable.
• Debt, new. provision.rs — curl for the https fetch, with --fail
  load-bearing (without it a 404 body is fetched and then reported as a checksum*
  *mismatch, i.e. exit 2 where 3 is correct).
• Debt, fixture-side. The provision TLS test stands up openssl s_server and
  generates key material with openssl req, and is Linux-gated because
  CURL_CA_BUNDLE is an OpenSSL-linked-curl trust surface.
• The whole mise-tasks/ layer is shell by design and out of scope here —
  its migration into the engine is what the DoR §2 amendment already drives, issue
  by issue (CLOUD-50 moved one).

What this issue must decide, per entry: in-process, stays shelled-out with a
stated reason, or blocked on something else. For the two real candidates the
question is concrete:

• git.rs → gix? It is pure Rust, but the links/framework question must be
  measured against macos-link-check first, exactly as CLOUD-90's was — the
  answer is not predictable from the crate's description, and this issue should
  not be refined on an assumption. The measurement is feature-sensitive rather
  than a yes/no on the crate: gix has selectable zlib backends and they differ
  on exactly the property under test — zlib-ng is C and declares a links key,
  zlib-rs does not.

  Correction, 2026-08-19. This bullet previously read "git.rs's
  patch-identity work shells out to git patch-id, which has no library
  equivalent, so a migration may be partial by necessity." That is false, and it
  was load-bearing — it is the sentence that made this entry look undecidable.
  git2::Diff::patchid() exists and has for years (libgit2's
  git_diff_patchid). The true constraint is stronger and is one this issue
  already knows from the provision.rs row: git2 depends on libgit2-sys,
  which declares a links key, so macos-link-check rule 1 excludes it
  outright with no measurement needed. The correct statement is not "no library
  has this" but "the library that has it is barred by the SDK-free macOS build."

  Two consequences for the verdict. First, gix shipping no patch-id verb is
  not a blocker: PatchId (git.rs:161) is only ever compared against ids
  produced by the same binary in the same run — patch_id_index against
  head_index inside landing — and nothing external computes one to compare
  against, so the requirement is a canonical deterministic patch identity, not
  git's. That is re-derivable on gix-diff plus the sha2 already vendored.
  Second, the current approach is already paying for the absence: DIFF_CONFIG
  pins 20 config keys and DIFF_FLAGS 6 flags (git.rs:100-146) purely to stop
  the host's git config from changing the diff bytes, and git.rs's own
  --binary comment concedes the identity is "deterministic for a given zlib but
  not guaranteed across zlib builds". Both costs vanish when the diff is produced
  in-process.

  Prior art, for whoever pulls this. Linking libgit2 through zig with no SDK
  is not something anyone does: libgit2 on macOS needs -framework CoreFoundation -framework Security, zig cannot resolve Darwin frameworks
  without a real SDK (ability to link against darwin frameworks (such as CoreFoundation) when cross compiling ziglang/zig#1349, open since 2018), and cargo-zigbuild's
  documented answer is SDKROOT or its Docker image with an SDK baked in. The
  SDK route is the licensing question release-artifacts.yml already names. The
  third option — a macOS runner — is declined here on cost, not capability
  (release-artifacts.yml:12-14: "GitHub bills macOS runners at 10x … this
  workflow uses neither"), and that is a lever this issue's ledger should record
  as a cost decision rather than a technical constraint. Meanwhile Cargo itself
  carries -Zgitoxide explicitly to replace git2 in full: the largest
  git-in-Rust consumer chose neither libgit2 nor a spawned binary.

• provision.rs → unblocked only if the TLS-linking constraint changes (a
  different macOS build strategy, or a pure-Rust crypto provider with no links
  key reaching production). Until then the honest state is "shelled out, with a
  measured reason", which is what the module documents.

Not in scope: relaxing macos-link-check. That reopens the Apple-SDK
question the gate exists to keep closed and is a separate decision.

Acceptance. Each inventory entry carries a verdict and, where the verdict is
"stays", the measurement that forced it — so the next person who reaches for a
library finds the answer rather than repeating the experiment. Specifically:

• Every row above resolves to exactly one of: in-process; stays shelled-out, with the measurement; or blocked on a named issue. No row is left implicit.
• The git.rs verdict is backed by a run of macos-link-check over a resolved
  gix with a pinned feature set, not by an argument about the crate.
• Where a verdict is "stays" for a reason that is a cost rather than a
  constraint, it says so in those words.

Filed at the user's direction while implementing CLOUD-90, rather than absorbed
into it.

Refinement — Ready (a verdict per inventory row, each backed by a measurement rather than an argument)

Refinement gate: Definition of Ready & Done. This body carries only specializations.

• Source of truth (§1). The inventory above is the authority for which shell-outs exist, and it stays in this issue rather than being copied into a repo docs/ tree (non-negotiable rule 7, gated by no-docs-tree). Where a verdict constrains code, its durable home is the module's own doc comment — provision.rs already documents its measured reason, and that is the shape the other rows follow. No new config surface and no second list of shell-outs.
• Computable predicate (§2). Per row, the verdict is decided by a command and an exit code, never by a reading: macos-link-check over the dependency graph resolved for aarch64-apple-darwin with the candidate crate and a pinned feature set, then cross-check linking both Darwin triples — because rule 2 of that gate is a hand-maintained list and is incomplete by construction, so a real link is what closes it. A row whose verdict is in-process is only Ready to implement once its measurement has run.
• Effect (§3). This issue lands a decision and doc comments; it changes no verb, no command path, and nothing in the derived read-only allowlist. Any row that later moves in-process is its own issue and declares its own effect there.
• Output & exit (§5). No runtime surface changes, so nothing moves in the output or exit contract. The measurements themselves are gates that already exist and already conform.
• Commit / bump (§6). docs → no bump — issue content plus module doc comments; release-plz releases nothing for a docs change.
• Test obligation (§7). No new test: the deliverable is a decision, and each verdict's evidence is the gate run named in §2, recorded in the row. The one durable assertion is that a row whose verdict is stays carries its measurement in the module doc comment, which no-docs-tree and the existing comment discipline already keep in the code rather than in prose elsewhere. A row that later becomes in-process carries its own test obligation on its own issue.
• Blockers (§8). None — every measurement this needs can be run today. relatedTo CLOUD-718, which is a second measured instance of the git.rs row's failure class (a caller-supplied ref interpolated into an argv string) and informs that row's verdict without deciding it; relatedTo CLOUD-90, whose measurement produced the provision.rs row.

CLOUD-737 Revisit the Darwin build strategy once the repository is public: the SDK-free zig build is priced by private-repo runner billing, not by capability

Why

Both Darwin release legs build on ubuntu-latest through cargo-zigbuild, with no Apple SDK (release-artifacts.yml:101-104). macos-link-check exists to keep that buildable: it refuses any dependency that would need a real SDK to link, and darwin-link (aarch64-apple-darwin) is a required check.

That is a sound design given the constraint. But the constraint is a price, not a capability limit, and the price is a function of the repository being private. release-artifacts.yml:12-14 records the reasoning in its own words: "GitHub bills macOS runners at 10x and Windows at 2x on a private repo; this workflow uses neither."

Verified 2026-08-20 rather than assumed:

• Standard GitHub-hosted runners are free and unmetered on public repositories, with no minute cap.
• On private repositories the monthly allowance is counted in Linux-equivalent minutes and macOS consumes them at 10x — so a 2,000-minute Free allowance is roughly 200 minutes of macOS.

So the day CLOUD-585 lands, the input that produced this whole strategy changes.

What this issue is for. Not "switch to macOS runners" — that is one candidate among several, and the current build works. It is for re-deciding, once, with the cost input corrected, rather than letting a decision made under private-repo billing quietly persist as though it were a technical constraint. CLOUD-320 asks for exactly this distinction and does not currently have the room to make it: "Where a verdict is 'stays' for a reason that is a cost rather than a constraint, it says so in those words."

What comes back into reach

• A real macOS runner, which resolves the SDK question by having one — SDKROOT is auto-detected on macOS.
• libgit2/git2. libgit2-sys declares a links key, so macos-link-check rule 1 excludes it outright today. That is not an impossibility: zig does not bundle Apple's frameworks (they are not redistributable), so cross-linking CoreFoundation/Security needs a real SDK — ziglang/zig#1349, open since 2018 — and cargo-zigbuild's documented workaround is to set SDKROOT to a macOS SDK path. The honest statement is "git2 needs an Apple SDK in the build", not "git2 cannot be built". Whether that is worth taking is a separate question from whether it is possible, and only the second one is currently settled.
• macos-link-check rule 1 itself, which is deliberately general and deliberately strict because the SDK is unavailable. With an SDK in play it may be narrower than it needs to be, or it may still be the right gate for a different reason (a smaller graph, a faster link). Either answer is fine; assuming the current one is not.
• Executing the Darwin artifacts on Darwin, which CLOUD-364 wants for its own reasons and which the same runner would supply.

What is NOT in scope. Relaxing macos-link-check before an SDK actually exists in the build. The gate is correct under today's inputs, and CLOUD-718 already landed the gix path that needs no SDK at all — so nothing is blocked on this. This issue changes no code on its own.

Note on the licensing half. An Apple SDK carries its own licensing question, which is why the current design avoids it rather than solving it. A macOS runner sidesteps that entirely (Apple's SDK on Apple's hardware, which is what the runner is for); vendoring or fetching an SDK onto a Linux runner does not. Those two are different decisions and should not be collapsed into "get an SDK".

Prior art already in the tree, so whoever pulls this does not re-derive it: Cargo itself carries -Zgitoxide to replace git2 in full, so the largest git-in-Rust consumer chose neither libgit2 nor a spawned binary. That argues the gix direction is right independent of the SDK question — which is a reason this issue is about re-deciding, not about reverting.

Acceptance

• Each item above resolves to: unchanged (with the reason restated under the new cost), or changed (with the change filed as its own issue).
• Where a verdict stays put for a cost reason, it says so in those words — CLOUD-320's rule, applied to the decision that issue's git.rs row was made under.
• release-artifacts.yml's comment either still describes the live reasoning or is corrected, so the next reader is not told a private-repo price about a public repo.

Filed by CLOUD-718, which measured the constraint while landing the first gix slice and had no place to put the finding that the constraint is a price.

Refinement — Ready (a decision re-run against a cost input that changed, not a code change)

Refinement gate: Definition of Ready & Done. This body carries only specializations.

• Source of truth (§1). The build strategy's authority stays where it is — release-artifacts.yml for how the artifacts are produced, mise-tasks/macos-link-check for what may enter the graph, and CLOUD-320's inventory for the per-row verdicts. This issue adds no fourth place and settles nothing on its own; it re-opens named decisions whose input changed. Where a verdict moves, the change lands in the file that already owns it.
• Computable predicate (§2). Per candidate, the predicate is the same pair that decided the gix verdict and is runnable today: mise run macos-link-check over the graph resolved for aarch64-apple-darwin, then mise run darwin-link for a real link. With an SDK actually present the second is the one that answers — rule 2 is a hand-maintained list and incomplete by construction, which is why the gate's own header defers to the link. "Is a macOS runner affordable" is not a predicate and is not treated as one: it is an owner decision this issue surfaces with the numbers attached.
• Effect (§3). read for the investigation. Any verdict that moves is its own issue with its own effect declaration; nothing here changes a verb, a command path, or the derived read-only allowlist.
• Output & exit (§5). No runtime surface changes, so nothing moves in the output or exit contract. The gates named in §2 already conform and are unmodified by this issue.
• Commit / bump (§6). docs → no bump — the deliverable is a recorded decision plus the comments that carry it; release-plz releases nothing for a docs change.
• Test obligation (§7). No new test: the deliverable is a decision, and each verdict's evidence is the gate run named in §2, recorded in the row it belongs to. The one durable assertion is the one CLOUD-320 already requires — a verdict that stays put for a cost reason says so in those words — so release-artifacts.yml's comment must either still describe the live reasoning or be corrected in the same change. A verdict that moves carries its own test obligation on its own issue.
• Blockers (§8). blockedBy CLOUD-585, and strictly: every item here is a consequence of the repository being public, so pulling this first would re-decide against the same inputs that produced today's answer. relatedTo CLOUD-320, whose git.rs row this supplies the cost half of; relatedTo CLOUD-718, which measured the constraint and filed this; relatedTo CLOUD-364, which wants a real Darwin execution for its own reasons and would be served by the same runner.

Clarify the runner-cost rationale.

darwin-link (macos-link-check) runs on the standard ubuntu-latest runner, not a macOS runner. State that the 10x macOS cost applies only to a possible native macOS runner, not to this workflow.
