Who is writing a commit is a question of its own, and a path is not a token - #116
Merged
Conversation
… token `prevent-author-mismatch` was declared by hand in 8 policy files across one consuming superproject and its submodules, byte for byte in every one: same id, same built-in, one `pre-commit` stage, no parameters. The guard is already compiled in, so what was missing was a set to carry the declaration. `mismatched-author` is that set, and it is its own rather than a rule inside an existing one. `unowned-push` asks where a ref is going; `host-identity` reads the running machine and then searches committed content for what it read, which is why it ships `stages = []`; `commit-message-residue` is about the text a commit records. This one asks who is writing, read off `git var` before a message exists. Its ceiling is the single `pre-commit` stage, so it cannot grow a second one without a diff on the line that says so. The header writes down what it costs -- a deliberate `--author` is refused as readily as an accidental one -- and the one thing it cannot do: with no global `user.email` there is no expectation to compare against, so it says so and declines. That is the container case verbatim, and a guard that quietly does not run in its own scenario reads like one that ran and found nothing. `no-hardcoded-home-paths` takes the leading `(?:^|[^A-Za-z0-9_.-])` boundary the same fleet had added to its shadow. Without it the pattern matches `/home` wherever those five characters land inside a longer token, and each such finding is a report on a file holding no home path at all. The corpus records both halves: the two ways a real path still opens a match, and the two shapes the boundary now lets through. Not taken: the same shadow's carve-out for a `u` placeholder user. That is a house convention tied to one repository's own record, and a bundled rule exempting a one-letter username would be exempting a real one. `policy/base/sets.lock.json` regenerated from the binary, not edited.

📝 WalkthroughWalkthroughThis change adds the bundled ChangesBundled policy updates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR adds a bundled pre-commit identity check, but machines without a global Git email setting can still create commits without author and committer verification, and the Windows home-path pattern can still match inside larger tokens. These create a concrete security bypass and bounded correctness risk, so merge should wait for fixes or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

Document protocol-relative and file:/// URL behavior. The boundary class in policy/base/process-residue.toml:83 includes /, so the regexp rule refuses text containing /home/alice within both //home/alice and file:///home/alice. The existing corpus only covers an HTTPS URL whose preceding character is t, so it does not define behavior for these forms. If these URLs are allowed, exclude / from the boundary class and add corpus cases. Otherwise, document that the rule intentionally refuses them.

Apply the token boundary to the Windows alternative.
Line 58 leaves [A-Za-z]:\\Users\\... outside the new boundary. Therefore prefixC:\Users\alice still matches inside an identifier-like token. Scope the boundary around the complete Unix-or-Windows alternation, then regenerate this lock file and add a Windows corpus case.

This branch sat on integration-2026-09-02, whose five branches have now landed on main as squashes (#116, #117, #123, #124, #126) alongside #129, so git saw the same lines added twice in src/scan.rs, src/shim.rs, src/text.rs, src/config.rs and tests/structural_documentation.rs. Resolved to the tree a rebase of this branch's own commit onto main produces: main's copy of all six, plus this branch's rule-as-a-type refactor on top.

Claude-Session: https://claude.ai/code/session_01HEudouCNhFHK6UPEWcWqXd * One table of what published text is judged by, reached from every seam `uphold hook` consulted the literal rules and the text-capable guards and never the prose rules, so every `prose_regexp` rule was dark at the MCP seam -- the whole bundled `prose-shapes` set among them, and those sets declare `command.before = ["gh", "git push"]` precisely because the text they judge is what an agent posts through `mcp__github__*`. `text::failures_in` excludes the prose rules on purpose, and each of the other whole-text seams carried its own compensating call to `prose::over_text` beside it. Four seams assembled the same ingredients by hand, so a rule kind added to three of them was silent in the fourth with nothing anywhere to say so. `text` now owns the answer. `Judged` names every kind of rule a piece of published text is judged by, `Seam::consults_every` says which kinds each of the four seams asks, and `text::judged` is the one assembly the three whole-text seams call. The shim keeps its own loop, because it holds a subject and a per-rule scope that function is not given, but it classifies each rule through `Judged::of` and asks the same table -- which also closes a second hole of the same shape: its editor pass dispatched `regexp` and `require_regexp` to the pattern checker and left `prose_regexp` to fall through to the `exec` consultation, where it was refused as a dispatch hole. Exit codes and report text are unchanged everywhere they already existed. The kinds run in one order, literals then guards then prose, which is the order each seam already printed the kinds it ran. Closes #111 Claude-Session: https://claude.ai/code/session_01HEudouCNhFHK6UPEWcWqXd * The shim reads the command line the command will read Five ways past this seam, reproduced against the built binary standing on PATH. Four of them ended in exit 0 with nothing printed, which is the shape of failure this tool exists to refuse. A renamed verb was one of them. A `match` list names verbs literally and every command here lets a person rename one, so `git -c alias.p=push p origin HEAD:refs/heads/x` and a persisted `[alias] p = push` both presented the verb `p`, matched nothing, and exec'd a push to a public forge unexamined. Where nothing matches, and only there, the word is resolved once against the command's own alias mechanism and matched again against the expansion. Asked of the real command rather than of whatever PATH resolves, because PATH resolves to this shim. A shell alias and a lookup that failed are could-not-looks and not absences: exit 2, since what a shell runs is not an invocation any table can read and it may well be a push. The refspec collector read one grammar where the matcher reads two. The matcher tries both arities for an option it cannot classify and matches under either; the collector took the bare reading and skipped two words, so `git --attr-source HEAD push origin` checked the remote's nickname while the branch went out unread. Both readings now, and where they disagree about which names are being published the answer is exit 2 rather than a guess. That needed git's own grammar filling in: the value-taking globals it was missing, and the `push` vocabulary, without which the disagreement fires on `git push -f origin topic`. A scope that could not be evaluated stood every checker down. `public-target` is the one predicate that asks somebody else, and a forge that cannot be asked answered `false` -- the same word as "the policy decided these checks do not apply here". So `prevent-unowned-target`, whose own contract is exit 2 on a destination it could not resolve, was skipped exactly where the lookup failed. Three answers now, and the third refuses before the command runs. `unresolved = "run"` on a `[[shim]]` opts back into the old behaviour and is refused at load beside a scope that cannot produce that answer. `--all`, `--mirror` and `--tags` name no refspec and publish many, and the fallback read HEAD, so a mirror push of forty branches was checked as one. They are enumerated with `for-each-ref` and each name is read. A leading `+` is grammar and no part of a name, and leaving it on made the force-push the way past a rule standing in front of the branch it names. `send-pack:*` joins `push:*` in the shipped table and in the checkers that name it: the plumbing publishes the same names from the same positions. The two stand-downs that remain -- an unresolvable subcommand, and `UPHOLD_ALLOW=all` -- keep their behaviour and are now stated as what they are: exit 0, the command runs, and a stderr line saying no checker did. A contract nobody wrote down is one a reader can only learn by reading the source. Also: `git.hooks` takes five names and one of them is `manual`, which is not git's. ADR 0001 and the type's own doc comment said githooks(5). Claude-Session: https://claude.ai/code/session_01HEudouCNhFHK6UPEWcWqXd * What a file's bytes say is decided once, and a host nobody can ask is not a pass Three seams were answering a two-valued question that has three answers, and each one spent the third answer on a green tick. WHAT A BLOB TURNED OUT TO BE. `guard::unicode` had the three-answer reader: byte-order mark first, git's NUL test for binary, and anything else that is not UTF-8 is unreadable and exit 2. Every other reader of the same blobs decoded with `String::from_utf8_lossy` or tested for a NUL and skipped. So a UTF-16 file naming a private repository was replacement characters with NULs between them in the tracked scan, a skipped image in the staged scan, and a decoded document in the codepoint guard, all in one run over one blob. The reader moves to `guard::scope`, beside `read`, because which bytes an operation introduces and what those bytes turned out to be are two halves of one question. The message readers go through it too: a message is text by construction, so bytes that will not decode are a message nobody read, which is exit 2 rather than a skip. What cannot be decoded joins the guard's could-not-look accounting, beside a name the forge would not answer for and outranked by a name that was found. A HOST NOBODY CAN ASK. `gh` answers for github.com and for nothing else, and the guard listed six other forges by hand and dropped every other host in silence: `github.acme.com/acme/secret`, a self-hosted forge, anything nobody had thought of. That is a silent third answer in the guard whose subject is that there is no such thing. Any `host.tld/owner/repo` this tool cannot ask about is unavailable now, which is exit 2, and what quiets one is a declaration rather than a list compiled in: `foreign_hosts`, host globs, at the top of the policy file for the reason `private_owners_from` is there and on a rule where one corner of the tree wants its own. Which hosts a repository cites is policy, which is `parameterize-do-not-enumerate` and what the hand list stood against. An owner whose escaped name would not compile into a pattern was dropped mid-search with nothing printed, so the operator's list said one thing and the guard looked for another. That is a config error at load now, as is a host glob that will not parse. EVERY CHECK READS THE SAME TEXT. `allowed_scripts` decoded under a covering `encoding` rule and stopped the run where nothing declared one. `regexp`, `forbidden_literals` and `require_regexp` reached the tree through a searcher with binary detection off and a lossy sink, so the same UTF-16 file was exit 2 for one check and clean for the other three. One reader in `scan` decides now -- UTF-8 where it is UTF-8, the declared charset where a rule declares one, the byte-order mark otherwise -- and hands text to the engine, which no longer opens files at all. A file nothing decodes goes into the unreadable list, which is reported beside the findings rather than instead of them; binary is the one skip. `require_regexp` gains the most: a file it could not read was a violation about a marker that may well have been in it. Beside the fixes: `redact_matches` was the one field a policy file may write that no document named, so REFERENCE.md documents it and a structural test now holds every public field of the serde-facing structs to being named there in code. ROADMAP said the Python script ships the reconcile step, which `uphold check` has done since it moved into the binary; README says what the script still does. DESIGN's account of which bytes a guard reads was missing the commit messages a push publishes. Closes #112 Closes #113 Closes #114 Claude-Session: https://claude.ai/code/session_01HEudouCNhFHK6UPEWcWqXd * This repository names the hosts its own text cites, because the binary no longer does Twenty-eight host globs at the top of the policy file, and every one of them was being answered by a list compiled into the binary that nobody could see or edit. Without them `no-private-repo-names-in-files` reports 55 names on hosts `gh` cannot be asked about, which is exit 2 at `pre-push` and at `manual`: a licence URL, a bibliography, a standards reference and a fixture publishing to `example.com` are all `host.tld/a/b`, which is the shape a repository name has and is not one. Four of the entries are documentation rather than citation and are noted as such in the file: `host.tld`, `github.acme.com` and `gitlab.com` are the worked examples the reference and this guard's own tests need to be able to write, and the `*.example.*` family is what every fixture publishes to. A working tree with an older uphold installed will find its `git` and `gh` shims failing closed on this file until the binary carrying `foreign_hosts` is installed, because a shim loads the policy with the uphold that is on PATH and an unknown field means the policy does not load. That is the same trade a new bundled set makes, and the cure is the same: install the build from this branch. Claude-Session: https://claude.ai/code/session_01HEudouCNhFHK6UPEWcWqXd * A forge API call that carries a body is a verb the shim stands in front of `gh pr edit` was unavailable to an agent whose token lacked read:org, so it ran `gh api -X PATCH repos/OWNER/REPO/pulls/N -F body=@file` -- the same body, the same account, the same public tracker -- and no `match` list named `api`, so the shim exec'd it with nothing printed and exit 0. The same hole stood in front of `gh api -X POST .../issues`, `.../comments`, `.../releases` and every `glab api`. The verb is not one a `match` list can simply name, and that is why it was missing rather than forgotten. One word is both the read side and the write side of a forge, so standing in front of `api` outright would stand in front of every GET on the machine -- including the `gh api repos/OWNER/REPO --jq .visibility` this shim itself runs to answer `public-target`, which is a shim standing in front of its own lookup. Which half an invocation is, is a question about its argv. So `api:*` is matched, and a second question is asked of the one verb that has to answer it: does this call carry a body at all. It does when `-X`/`--method` names something other than GET, or when any field or `--input` is present, which is when gh switches to POST anyway. A GET with no fields is left exactly where it was -- unmatched, unexamined, exec'd. The call is read with the verb's own grammar rather than through the table's flag lists, because they disagree: `-F` is `--body-file` on `gh pr create` and `--field` on `gh api`, so one vocabulary answering for both reads a `key=@file` pair as a body file or a body file as a field. Every field value becomes a text subject, with `@file` read from the file and `@-` from stdin, replayed to the command on the way through the way a `--body-file -` already is. An `--input` file is judged one string value at a time where it is JSON, because the encoding otherwise hides the sentence a prose rule stands in front of behind its escapes, and whole where it is not -- and JSON here means a document that starts with `{` or `[` and parses as one, not YAML's superset reading, under which an ordinary Markdown body with a `Note:` line parses as a mapping and most of it reaches no checker. The endpoint path is the destination. `repos/OWNER/REPO/...`, and GitLab's `projects/OWNER%2FREPO`, resolve to the same `owner/repo` a `--repo` resolves to on every other verb, so `prevent-unowned-target` and a `public-target` scope read a `gh api` call exactly as they read a `gh pr create` one. A path naming no repository -- `gh api graphql`, `gh api user` -- falls through to the table's own resolver, which is the honest bound: the destination of a GraphQL mutation is inside its query and nothing in a path can say. Five tests: a PATCH whose `-F body=@file` trips a text rule refuses at exit 1, a GET with no fields runs, an `--input` JSON is refused for one string value and runs when that value is ordinary, a body bound for an owner this workspace does not have is refused by the destination guard while the same call under its own owner runs, and a GitLab project id is the same destination with its separator escaped. Closes #125 Claude-Session: https://claude.ai/code/session_01HEudouCNhFHK6UPEWcWqXd * Whose name it is decides what a host nobody can ask about means An unaskable host was one answer for every name written against it, and exit 2 for all of them made the cure "enumerate every host you cite" in every consuming repository. That is the enumeration ADR 0001 refuses, moved out of the binary and into eighty policy files, which is worse than where it started: a consumer publishing a pull-request body was refused over `claude.ai/code/<id>`, and this tree needed twenty-eight host globs to say its bibliography is a bibliography. The split is by owner, because the owner is what the rule is about. A name under a declared `private_owners` owner, or under the `owner` this policy says the workspace is, on a host `gh` cannot be asked about, is could-not-look and exit 2: that is the name this rule exists to keep off a public target, and silence about it is not a pass. Every other `host.tld/a/b` goes back to the unresolved bucket it was in -- reported on the way past, refused only where the repository has set `refuse_unknown` -- because a DOI, a licence URL and an encyclopaedia article all have the shape of a repository name and none of them is one. `foreign_hosts` keeps its job and gains no new one: it says a host is not a forge at all, and it quiets both rows. Nothing is quieted by default. The twenty-eight globs come back out of this repository's own policy. They were load-bearing only under the wider default, the guard passes at `manual` without them, and a policy field carrying a list nobody needs is the enumeration again wearing a smaller number. Claude-Session: https://claude.ai/code/session_01HEudouCNhFHK6UPEWcWqXd * A rule is one check carrying its own knobs, so the four lists that said which fields name a check are the type `Rule` was thirty-eight `Option` fields in one flat struct, fourteen of them mutually exclusive check selectors and ten more knobs that one check each reads. "Which fields name a check" was written out four times -- an array to count them, a sentence to list them in the error, a reader to answer which one was set, and a third list for the built-in parameters -- and nothing held the four to each other. `Check` is now an enum with one variant per check, carrying only what that check reads: `exclusive` sits in `AllowedScripts`, `ignore_literals` in `ForbiddenLiterals`, the sixteen built-in settings in a `Parameters` that only `Builtin` has, and the two spellings of the literal source are one `Literals` field with two arms. A rule holding two checks, or a knob beside a check that reads none, is not a state that can be built. `Check::of_written` is the one reading that is left, and the only place a file can still say two things. It is where the refusals live now, with their text unchanged: a rule naming two checks, a rule naming none, `forbidden_literals` beside `forbidden_literals_from`, `trivial_comments = false`, and a knob or a parameter written beside a check that does not read it. What the type cannot decide stays a check -- WHICH built-in reads which parameter is a question about a name, so `Parameters::refuse_unread` and `guard::parameters` still meet at load, in one function serving both the wrong-check and the wrong-built-in case rather than the two that used to say it separately. ## Why the conversion is not the deserializer Every refusal above names the rule a reader has to go and edit, and the id is the section header rather than a field, so it does not exist until `parse` has the map key. `Written` is the flat shape a file deserializes into, unchanged and still `deny_unknown_fields`; `parse` reads each one as a check the moment it has an id. An untagged enum would have moved these messages inside serde and lost both the id and the sentence. ## What the rest of the crate sees `Rule` keeps every accessor that had one and gains one per check value, so no caller reads a field that might belong to a different check: `rule.encoding()`, `rule.max_lines()`, `rule.regexp()`, `rule.allowed_scripts()`. `Rule::check() -> Option<CheckKind>` becomes `Rule::kind() -> CheckKind`, total, because there is no rule without a check any more. The old `Check` discriminant is `CheckKind` -- same variants, same order, same `as_str`, same `ALL`. `Rule::synthetic` takes the check itself rather than a kind, so the seven callers that built a rule and then set a field now say which check they mean in one expression. ## Serialization `uphold rules --sets --json` is byte for byte what it was: the enum is `#[serde(untagged)]` and flattened into `Rule`, so a variant's fields serialize as the flat keys a policy file writes, and the document is still derived rather than written by a function naming the fields it knows about. Diffed against the output of the binary built before this change, and against `policy/base/sets.lock.json`, which is unchanged. No `policy/*.toml` was touched. ## The file `src/config.rs` goes from 4657 lines to 3320, and the rule type moves to `src/config/rule.rs` at 1844. The two together are 507 lines more than the one was: the four lists and three validators that went are worth less than the per-variant documentation, which is the same prose in a place a reader meets it beside the check it is about, plus one accessor per check value. ## Tests 759 pass, 25 suites, up from 758 -- one new test, `the_field_a_file_writes_is_ the_check_it_loads_as`, which is the direction the type cannot keep on its own: a mis-wired arm in `of_written` would load a `max_bytes` rule as a `max_lines` one with nothing to notice. Two existing tests changed, both because the schema moved rather than because an assertion did: - `structural_documentation` held `Rule`'s public fields to being named in REFERENCE.md. It holds `Written`'s now, which is the struct a policy file is deserialized into and carries the same field names; and it reads both `src/config.rs` and `src/config/rule.rs`, because a reader of one alone would find none of the other's fields and assert about nothing. `config.rs::Rule` also leaves its undocumented-declaration list, having gained a doc comment. - `every_check_is_named_by_the_field_that_selects_it` asserted `rule.check() == Some(check)`; it asserts `rule.kind() == check`. No test asserting an error message needed changing: every refusal a test names is produced with the same words, from the conversion instead of the validator. `cargo build`, `cargo test`, `cargo clippy --all-targets` with warnings denied, `cargo fmt --check` and `prek run --all-files` are clean. Based on `integration-2026-09-02`, which carries #116, #117, #123, #124 and #126 -- all five touch `src/config.rs` or the shim that reads a rule, and this sits on top of them rather than under any one.

… unknown that is no longer a pass (#132) Point the documented pins at 1.14.0 and bump the crate version. Minor, not patch. This release carries names a policy written against 1.13.0 cannot use: the bundled set mismatched-author; api:* as a matchable verb on the gh and glab shim tables, so a forge call that carries a body is read the way gh pr create is; unresolved on a [[shim]] table, whose default refuses before exec where a scope could not be evaluated; and refuse_unknown, foreign_hosts and redact_matches on the private-name family. It also closes four seams that reported a pass they had not established. The MCP hook seam consulted no prose rule, so every prose_regexp was dark exactly where an agent publishes. Five command lines walked past the shim, four of them ending in exit 0 with nothing printed. A blob no charset decodes was read as clean rather than refused. A forge host nobody could ask about produced no finding, no report and no exit code. Landed in this release: #116, #117, #123, #124, #126, #129, #131. A policy written against 1.13.0 loads unchanged, and every new name has to be named or inherited to run. Two things do change for a consumer who only bumps a rev or a ref: the seam fixes above start refusing text and command lines that used to pass unexamined, and the four published Go ids are triggered by the module rather than by the file that changed, at all four stages rather than at pre-commit alone.

Closes #115.
Two promotions and one finding, drawn from what the consuming fleet was
already running by hand. The middle item turned out to need nothing, and it is
written up rather than dropped because "already covered" and "nobody looked"
read the same in a diff.
mismatched-author, a new bundled setCarries
prevent-author-mismatchatpre-commit, and nothing else. The guardis already compiled in (
src/guard/identity.rs); what was missing was a set tocarry the three-line declaration that 8 policy files in one superproject and
its submodules were each writing out byte for byte.
Its own set rather than a rule inside an existing one, argued in the file
header:
unowned-pushasks where a ref is going,host-identitysearchescommitted content for what it read off the machine and ships
stages = []onpurpose,
commit-message-residueis about the text a commit records. This askswho is writing, and it reads the answer from
git varbefore a message exists.[set] stages = ["pre-commit"]is the ceiling, so the set cannot grow a secondstage without a diff on that line.
The header also writes down the cost and the one thing the guard cannot do: on
a machine with no global
user.emailthere is nothing to compare against, soit prints a note on stderr and declines. That is the container case verbatim,
which is why the note is not decoration.
no-pinned-tool-install-- already absorbed, no change hereThe
--with [A-Za-z0-9_.-]+==[0-9]alternative that the two shadowingrepositories appeared to be keeping a local copy of the rule for is already in
the bundled pattern on main, and
tests/fixtures/promotion-corpus.jsonalreadycarries a line for it. Their shadows are not stricter than base; they are
narrower, having never gained the
cargo install --tagor^\s*ref:alternatives added since. There is nothing to promote, so this branch touches
neither the pattern nor the corpus, and the two copies are deletable as they
stand.
no-hardcoded-home-paths, a leading boundaryAbsorbs
(?:^|[^A-Za-z0-9_.-])in front of the alternation. Without it thepattern matches
/homewherever those five characters land inside a longertoken, and each such finding is a report on a file holding no home path at all.
Two
allowslines record what the boundary bought (a URL route calledhome,a repository-relative directory of the same name) and two new
refuseslineshold the two ways a real one still opens a match: at the start of a line, and
after a character that is not an identifier character.
Not absorbed: the
uplaceholder carve-out. The same shadow lets/home/u...through so a document quoting tool output can neutralise ausername and still pass. That is a house convention tied to one repository's
own ADR, not a general property of home paths, and a bundled rule that exempted
a one-letter username would be exempting a real one too. That repository keeps
its shadow, for that reason and no longer for the boundary.
What a consumer can delete once this is released
[rule.prevent-author-mismatch]block, in each of the 8policy files that carry it, in favour of
mismatched-authorin the[inherit] setsline;[rule.no-pinned-tool-install]shadow in the two repositories thatcarry one -- deletable today, on the released binary, and not on the strength
of this branch: both are already strictly narrower than the rule they shadow;
[rule.no-hardcoded-home-paths]shadow, in any repository that waskeeping it only for the boundary.
The warning that goes with a new set
A new bundled set changes the set list, and the list is what the loader
validates an
[inherit] setsline against. A consumer that adds"mismatched-author"while its pinned binary predates this release will failto load its policy entirely -- not run the set and skip the rule, but refuse
the whole file -- until it bumps the pin. This is expected, and the order is:
bump the binary first, then add the set name.
