feat(rhodibot): read the RSR rules from the canon, and pin them - #543
Merged
Merged
Conversation
Rhodibot's compliance rules were a hand-written table compiled into rsr.rs:
paths, points and severities decided once by hand and edited by hand ever
after. The canon says what that table should be:
0-canon/rsr/rsr-criteria-v2.a2ml is "the SINGLE SOURCE OF TRUTH ... Every
other artefact -- the prose checklist, the one normative checker's rule
table, and the badge thresholds -- is GENERATED from this file."
So the rule table belongs downstream of the canon. `src/canon.rs` reads the
canon's A2ML record dialect into typed data: 11 weighted categories, 74
criteria, each with its tier, capability gate, detection rule and template
reference. Nothing about the rules is restated in Rust.
The copy is vendored with its released identity recorded in canon/pin.toml --
canon 2.0.4, digest 37cb5f67..., 11 categories, 74 criteria, weights summing
to 88. The digest proves the bytes; the counts prove the shape, because a rule
set that silently shrinks is the failure that matters here, and a hand-edited
file can carry a hand-edited digest.
Parsing is validated rather than trusted, and refusing is the point:
- a duplicate criterion id, a criterion filed under the wrong category, an
invented tier, or a misspelt category field is an error
- the canon's own [weights-check] arithmetic must hold, and must be present:
that section sits at the end of the file, so a truncated copy loses it
along with whatever was cut, which is exactly when a missing check would go
unnoticed
- an unterminated criteria list is an error rather than a smaller rule set
Rhodibot is not the oracle and this does not make it one. RSR v2.0 designates
hypatia's `rsr-conformance` rule family as the single normative checker, and
the canon explicitly retires the tools of this shape (`rsr-audit.sh` demoted to
a non-normative reference, `rsr-check.scm` retired, `rsr-certifier` named as
"product, not the spec's oracle"). Rhodibot consumes the canon and reports
against canon criterion ids; it stays advisory.
`scripts/check-canon-drift.sh` asks the other question -- has the canon moved
since the copy was pinned? -- and runs on the rhodibot matrix entry in rust.yml.
Upstream is publicly readable, so no secret is needed.
Tests: 18 unit tests for the parser and pin, 4 integration tests for the
binding. 117 in total. Each fail-closed case is a test: duplicates, misfiling,
invented tiers, broken arithmetic, truncation, unterminated lists, a bad pin and
a canon that is internally consistent but smaller than the pin. Both the script
and the pin check were run against a deliberately broken input and fail:
pinned 37cb5f679b414f6ee99c6bb62c460fd5349ff7d50cc1dab25b1e1a8e8d3c7bb9
upstream 37cb5f679b414f6ee99c6bb62c460fd5349ff7d50cc1dab25b1e1a8e8d3c7bb9
-> unchanged since it was pinned
pinned deadbeef... (a corrupted pin)
-> exit 1

Construct the default remote from source.repo.
CANON_PIN can select a pin for another repository. However, REMOTE always selects hyperpolymath/standards, and the parsed repo value is only printed.
This can compare an alternative pin with the wrong upstream file. Read repo first, validate it, and use it to construct the default raw URL.

Fail when canon.lock cannot prove agreement.
The documented success condition requires canon.lock to agree with the fetched file. The script currently exits successfully when the lock is unavailable or does not contain a recognised criteria hash.
This permits CI to pass without checking the lock invariant. Call fail in both cases.
Proposed fix
lock_hash="$(grep -A2 'criteria = {' "$lock_file" | grep -oE '[0-9a-f]{64}' | head -1)"
if [ -z "$lock_hash" ]; then
- printf ' canon.lock: no criteria pin found (format changed?)\n'

The canon names the files a criterion is about in `desc`, not in
`template_ref` -- `template_ref` is where the *template* satisfies it, and
reading it as a requirement invented the pilot's entire false-positive
class (1.2.2 names no directory; a root .pre-commit-config.yaml is
compliant).
`requirement_from` reads the description instead:
- `and`/`+` join required files; `or`/`/`/`,` list acceptable locations
- `{a,b}` expands, and the splitter is brace-aware, so the commas inside
`.well-known/{security.txt,ai.txt,humans.txt}` do not tear it apart
- the splitter steps by character, not byte: the descriptions carry em
dashes and byte-stepping cut them in half
- `.gitignore`/`.editorconfig` are files; `.md`/`.a2ml` are extensions
- negations (`No Makefile ...`) and unresolvable alternatives
(`CHANGELOG.adoc, or .md`) are refused rather than guessed at
- `Requirement::is_anchored` separates `anchors/ANCHOR.a2ml` from a bare
`STATE.a2ml`: the canon gives the directory in a neighbouring criterion,
and asserting a root path it never gave is how a check reports every
repository as missing a file it has
31 of 74 criteria yield a requirement; a lockstep test prints them and
asserts the count stays partial, so a description that stops parsing
fails rather than silently checking less.
Advisory only -- rhodibot reports against canon criterion ids.

…s the capability (#545) Second of the four steps that make the canon's criteria into checks (the first, reading requirements from `desc`, landed in #543). ## Why 26 of the canon's 74 criteria are gated on a capability. Asked as universal questions they demand files a repository has no reason to carry -- an FFI seam from a docs site, a container from a library. That is the same mistake as reading `template_ref` as a requirement, one level up. ## What `src/canon/profile.rs` reads `.machine_readable/rsr-profile.a2ml`: - effective set = `(direct list | preset expansion) + add - remove`, the gate table's own model; - `Applicability` is `Universal`, `Declared(capability)` or `NotDeclared(capability)`; a gated criterion leaves the denominator as `na` rather than counting against the repository; - a misspelt capability, an unknown preset, a misspelt key, and removing something never declared are all refused. `capabilities = ["russt"]` quietly collapsing to an empty set would switch a whole gate of checks off and report the repository as clean. The gate table is vendored and pinned like the criteria -- same release, same rule -- under `[gates]` in `canon/pin.toml` (`b65ce754...`, matching `canon.lock`'s `gates` slot and the spine profile's `gates_sha256`). `scripts/check-canon-drift.sh` now checks both artefacts against the canon and against `canon.lock`; the failure paths are exercised (a forged pin for either slot exits 1). `GateTable::unknown_gates` fails if a criterion gates on a capability the vocabulary does not define, because such a criterion can never become applicable: that is how `deno` came to be listed. ## Numbers Against the five pilot repositories, which declare nothing: of the 31 criteria whose description names files, **22 are scored and 9 are `na`** (6 governance-tier, 2 web-ui, 1 docs-site). All 11 universal criteria the earlier pilot was run against are in the scored set, so those results still hold. ## Verification - `cargo test --locked` -- 96 lib + 9 lockstep + 50 integration, all pass - `cargo clippy --locked --all-targets -- -D warnings` -- clean - `scripts/check-canon-drift.sh` -- exit 0 against `main`; exit 1 when either pin is forged - `rustfmt --edition 2024 --check` clean on every file touched Advisory only: rhodibot reports against canon criterion ids; hypatia remains the canon's single normative checker.

Third of the four steps that turn the canon's criteria into checks (steps one and two landed in #543 and #545). A criterion that names files has four possible answers, and they are not interchangeable: | verdict | meaning | worth | |---|---|---| | present at the path | the file is where the canon records it | nothing to do | | present under a retired location | the file exists, in a place the canon has retired | move it | | present elsewhere | the file exists, in neither place | check it | | absent | the file is not there | add it | ## The rule this holds **The description decides what is required; `template_ref` only says where the canon's own template keeps it.** The advisory pilot read `template_ref` as the requirement and failed repositories that satisfied the criterion elsewhere -- both of its false positives were criterion 1.2.2, satisfied by a root `.pre-commit-config.yaml` even though the template keeps its copy under `ci/`. A bare filename -- "STATE.a2ml", "Justfile" -- is accepted in the two places that are unambiguously the repository's own: **the canon's recorded location, or the repository root**. Everywhere else is `Elsewhere`, a finding, with the canon's location named as a note. Both halves of that rule were learned by running this against real trees: - **"anywhere"** passed `1.2.4` (`.tool-versions`) on a copy at `robot-repo-automaton/templates/skeleton/.tool-versions` -- another project's template skeleton; - **"root only"** would have failed gitbot-fleet's `.machine_readable/descriptiles/*.a2ml`, which satisfy 3.1.2-3.1.7 exactly where the canon keeps them. A description that gives a path (`.well-known/security.txt`) still means that path: a copy elsewhere is `Elsewhere`. ## Retirements are read, not hardcoded The canon states `.machine_readable/6a2/` is retired -- in prose, inside criterion 3.1.1's description: "NOT 6a2/, which is deprecated 2026-06-30". There is no machine-readable deprecation table, so the sentence is parsed, resolved against the criterion's own `template_ref`, and asserted by a lockstep test. A canon that stops saying it fails the test rather than quietly reclassifying every retired path as ordinary. ## Details the real trees forced - a repository holding the file in **both** a live place and a retired one is `relocated` with the leftover named, not `deprecated`: the move is under way, and "deprecated location" would overstate it (nesy-solver, 3.1.2-3.1.4); - an absent file names what is sitting there instead -- gitbot-fleet has `CODE_OF_CONDUCT.adoc` where 2.1.4 asks for `.md`, and a bare "absent" would send a reader looking for a file that is right there under another name; - severities are ordered `Missing > Deprecated > Relocated > Satisfied`. ## Against real repositories Trees read on 2026-09-19: | repository | satisfied | relocated | deprecated | missing | |---|---|---|---|---| | nesy-solver | 12 | 4 | 3 | 3 | | gitbot-fleet | 17 | 3 | 0 | 2 | The pilot's own record for nesy-solver -- three findings, all descriptive files left under the retired path -- is asserted in the lockstep suite, as is 1.2.2 staying fixed. ## Verification - `cargo test --locked` -- 117 lib + 10 lockstep + 50 integration, all pass - `cargo clippy --locked --all-targets -- -D warnings` -- clean - `scripts/check-canon-drift.sh` -- exit 0 - `rustfmt --edition 2024 --check` clean on every file touched Advisory only: rhodibot reports against canon criterion ids; hypatia remains the canon's single normative checker.

… line (#549) Fourth and last step of the canon-sourced rules (#543, #545, #547). The three pieces before this one read the rules from the canon, decide which criteria apply, and classify what was found. Nothing ran them. This adds `rhodibot canon`: ```sh rhodibot canon --owner hyperpolymath --repo ubicity rhodibot canon --path /path/to/checkout --format json rhodibot canon --owner O --repo R --fail-on missing ``` **Advisory by default** — exits 0 whatever it finds. The canon designates hypatia's `rsr-conformance` as the single normative checker, so a gate here would be a second opinion claiming an authority it does not have. `--fail-on` is opt-in. ## Two details that carry their weight - `GitHubClient::tree_paths` asks once for the whole file list and **refuses a truncated response**. A partial tree is missing files, a missing file reads as an absent one, and the report would manufacture findings against a repository that has the file. - `get_file_content_if_present` distinguishes 404 from everything else: an absent `rsr-profile.a2ml` means "declares no capabilities", a 500 means "could not read the declaration". Treating the second as the first would silently shrink the check to the universal criteria and report a cleaner scorecard than the truth. `canon/report.rs` assembles the report (counts, findings worst-first, retired locations quoted) and serialises to JSON. `canon/local.rs` reads a checkout, preferring `git ls-files` over a walk — a walked list includes build output, and a `CODE_OF_CONDUCT.md` inside `target/` is not the repository's code of conduct. ## The pilot re-run through the tool Unauthenticated, against the five repositories of the advisory pilot: | repository | at path | elsewhere | deprecated | absent | |---|---|---|---|---| | gitbot-fleet | 17 | 3 | 0 | 2 | | ubicity | 7 | 2 | 6 | 7 | | awesome-nickel | 8 | 1 | 7 | 6 | | julia-professional-registry | 8 | 1 | 7 | 6 | | nesy-solver | 12 | 4 | 3 | 3 | **110 questions, 52 satisfied, 58 findings** (11 relocated, 23 at the retired `6a2/`, 24 absent). 22 of the canon's 74 criteria apply to every one of them: 26 are gated on a capability none declares, 26 more ask content questions rather than naming files. The 23 files under `.machine_readable/6a2/` are still 23, re-derived from criterion 3.1.1's own sentence about the retirement rather than from a hardcoded path, with the same per-repository breakdown as the hand run. Both of the hand run's false positives (criterion 1.2.2) now come back satisfied. ## Two findings the earlier scope could not see - `2.1.3` asks for `SECURITY.md`; `ubicity` has `SECURITY.adoc`. The verdict is `absent` and the report now says what is there instead. Same for `CODE_OF_CONDUCT.md`/`CODE_OF_CONDUCT.adoc` at `2.1.4`. If `.adoc` is the estate's convention, the canon is where that belongs. - `2.2.1` is `relocated` for all five: the `.well-known/` files live inside a `www/` publication bundle, not at the repository root the criterion names. The origin-versus-repository question is worth an answer. ## Verification - `cargo test --locked` — 135 lib + 10 lockstep + 50 integration, all pass - `cargo clippy --locked --all-targets -- -D warnings` — clean - new wiremock tests cover the tree listing (directories excluded), the truncated tree refusal, and 404-versus-500 on the optional file read - `scripts/check-canon-drift.sh` — exit 0 against upstream `main` Signed-off-by: Jonathan D.A.

Rhodibot's rules were a hand-written table compiled into
rsr.rs: paths, pointsand severities decided once by hand, then edited by hand ever after. The canon
says what that table should be — and says it about the table specifically:
So the rule table belongs downstream of the canon.
src/canon.rsreads thecanon's A2ML record dialect into typed data: 11 weighted categories, 74
criteria, each carrying its tier, capability gate, detection rule and template
reference. Nothing about the rules is restated in Rust.
Pinned, by bytes and by shape.
canon/pin.tomlrecords the releasedidentity: canon 2.0.4, digest
37cb5f67…, 11 categories, 74 criteria, weightssumming to 88. The digest proves the bytes; the counts prove the shape — a rule
set that silently shrinks is the failure that matters here, and a hand-edited
file can carry a hand-edited digest.
Parsing is validated rather than trusted, and refusing is the point:
weigth = 12would drop a weight and change every score[weights-check]arithmetic broken — or absentcriteria = [listRhodibot is not the oracle, and this does not make it one. RSR v2.0
designates hypatia's
rsr-conformancefamily as the single normative checker,and the canon explicitly retires tools of this shape:
rsr-audit.shdemoted to"non-normative reference only",
rsr-check.scm"retired with the .scm era",rsr-certifiernamed as "product, not the spec's oracle". Rhodibot consumes thecanon, reports against canon criterion ids, and stays advisory.
scripts/check-canon-drift.shasks the other question — has the canon movedsince the copy was pinned? It runs on the rhodibot matrix entry in
rust.yml.Upstream is publicly readable, so no secret is needed.
Proven, not asserted. 18 unit tests + 4 integration tests; 117 in the crate.
Every refusal above has a test, and both the script and the pin check were run
against deliberately broken input:
Two canon facts worth recording, both found while doing this and neither
resolved here:
canon.locksays 2.0.4 while the criteria file's own[meta] versionstill reads2.0.0-draft(both are quoted in the pin), and itscommitfield is still the all-zero placeholder commented "fill at release", sothe pin describes the artefact by digest rather than by commit.
Next, not in this PR: the checks that act on these criteria, and the ~5-repo
advisory pilot with a false-positive count.
