In `@crates/batten/src/policy.rs`:
- Around line 908-918: Update the tokens construction in the policy-checking
flow to reuse the complete registry from registry_for(verdicts), including
consumer, native, and preset verdict rows, before calling check_collapse(rules,
&per_rule, &tokens). Preserve the existing filtering of retired entries and
avoid rebuilding a narrower consumer/native-only set.
In `@crates/batten/src/verdict.rs`:
- Around line 892-897: The rule-ID words collected in check_rule_id are
discarded in a local used set, so validate_no_orphan_words cannot see them.
Update the verdict validation flow to retain and merge rule-ID usage into the
shared used set before the orphan-word check, while preserving normalise_rule_id
and check_name validation behavior.
In `@policy/ancestry-decides-nothing.rego`:
- Line 60: Update the expected violation string in
test_the_verb_in_command_position_is_refused from "ancestry-decides-nothing" to
"patch judge wrong", leaving the rule behavior and other assertions unchanged.
In `@policy/module-layering.rego`:
- Line 60: Update test_the_documented_cycle_claim_is_refused to assert the
current violation.rule identifier "layer place wrong" instead of the stale
"module-layering" value, leaving the rule definition unchanged.
In `@policy/spawn-adapters.rego`:
- Line 194: Update the local v.rule assertions in the tests around the affected
violation paths to expect the canonical identifier "adapter place missing"
instead of "spawn-adapters". Apply this change to both assertions near the
referenced test cases and leave unrelated expectations unchanged.

Feed rule-ID usage into orphan-word tracking. verdict::validate runs before config::validate_tables checks [[rule]] IDs. check_rule_id writes to a local set, so validate_no_orphan_words ignores rule IDs. The shipped configuration contains words used only by rule IDs, including fact, pattern, verdict, and fix. Configuration loading can therefore reject valid vocabulary as orphaned. Add rule-ID words to the same used set before the orphan check.

The first of CLOUD-1638's three arms, landable alone: `check_rule_id` and `normalise_rule_id`, not yet wired to load. Wiring them is the enforcement and cannot precede the migration of the 136 ids they will judge. THE SAME CHECKER, DELIBERATELY. A rule id and a class token are two names a reader meets in one line, so this is `check_name` with the id normalised first, not a fork of it. A second grammar would be a second thing to learn for no gain. Three spellings in, one out. An id reaches the engine from a `[[rule]] id`, a module's `"rule":` literal, a `//MUTANT` row and a `policy rule` argument, and those surfaces do not share a house style; accepting `-`, `_` and space at the boundary and storing only the space form is what keeps the id ONE name. Two spellings of an id would be the same two-names-for-one-thing this row exists to remove, one level down. The space form is also the cheap one — measured over the declared set, space 3.01 tokens against snake 3.94 and hyphen 4.41. Four cases: three spellings normalise to one; an undeclared word is refused; wrong arity is refused in both directions, since a two-word and a four-word id fail for the same reason and only one is obvious; doubled separators collapse rather than minting an empty word that would fail the arity arm naming the wrong defect. Refs: CLOUD-1638
The migration arm: every `[[rule]] id`, every `[[waiver]] rule`, every module `rules contains` and `"rule":` literal naming one of them, and every `--rule <id>` invocation that reaches a row by name. TWENTY OF THEM COLLAPSE. Where a row raises exactly one class AND that class has exactly one raiser, the id IS the class token — `leased-push` becomes `branch write unsafe`, `task-substitution` becomes `task run loose`. The other 116 keep a distinct name, because they do not name one thing: 39 policy rows raise more than one class (`ci-parity` raises 21), and the 70 native-kind rows share their kind's class, where the id is the only discriminator. STRUCTURAL POSITIONS ONLY, and the first attempt is recorded because it was wrong. Rewriting every quoted or backticked occurrence touched 274 files and 1248 sites — including prose in `mise-tasks/perf.sh`, where `perf-assert` is ALSO a task name, so the comment came out saying something false. Reverted and redone against the positions that actually hold a rule id. `--rule` is one of those positions and was missed on the first pass; `hooks-wiring-check` caught it by refusing `--rule harness-wiring` against a config that no longer declares it. The task's own comment predicted exactly that: "a renamed row breaks this loudly instead of silently passing." The new spelling is quoted so the space form stays one argv word. Names are chosen, not derived: none of the 116 fell out of its old kebab id mechanically, so each was read off the row's own `reason`, `pattern` or module and validated for arity, slot membership, uniqueness, and — the arm that caught three — not colliding with a class token some other row raises. `config-lint` and `hooks-wiring-check` green over the renamed set. The grammar is not yet ENFORCED at load; that is the next commit, and it could not precede the ids it judges.

Its whole subject is the id grammar, and the ids live in batten.toml — there is no other file to change. Admits-answer-precondition: No surface can express this change: `config read first` reads batten.toml and `patch run first` restores it, and neither writes. CLOUD-1638 requires every `[[rule]] id` to move into the three-word grammar, which is a rewrite of 136 declarations in the authority itself; the write is a reviewed diff in the PR closing CLOUD-1638. Admits-answer-rejected-route: I rejected `patch run first`: it restores the authority rather than editing it, so it undoes the change instead of making it. `config read first` does not apply either — it is a READ of the file, and I have already read it to derive the census (136 rows, 20 collapsible); it leaves every id unmigrated.
… names are one The enforcement and collapse arms. The grammar could not be wired before the ids it judges, so it lands after the migration rather than with it. GRAMMAR, at parse. Every `[[rule]] id` and `[[waiver]] rule` is normalised to the space form before validation, so each later reader — a gate, the emitted line, `policy rule`, a receipt, a re-emitted config — sees one spelling. Then each is held to the same vocabulary a class token is. The opt-out is inherited rather than restated: a consumer declaring no word lists cannot satisfy membership, so it is exempt exactly as `verdict::validate` exempts it, and the two names cannot diverge on the trees that have adopted neither. COLLAPSE, and the predicate is a property of the PAIR in both directions. A rule id equals a class token iff the rule raises exactly one class AND that class has exactly one raiser. Both are refused: a row satisfying both whose id differs (two names for one thing), and a row not satisfying both whose id equals a class (one name for two things, which is worse — a reader who dereferences it is answered about the other one). A native-kind row raises no module class, so the second clause covers it without a special case. The issue asked for the first direction only, on a census that counted classes-with-one-raiser and read it as rules-with-one-class. Measured here: 20 policy rows raise exactly one class, 39 raise more, `ci-parity` raises 21. The one-directional rule would have demanded `ci-parity` carry 21 ids at once. THE TWO ARMS REFUSED EACH OTHER FIRST. Collapse renames the trunk-based preset row to `trunk push forced`, and `trunk` is a VENDORED word no consumer vocabulary declares — so the grammar arm rejected the name the collapse arm required, and no tree could satisfy both. A collapsed id is governed by the class registry, not the consumer list, because re-checking it here would be a second authority over one name. Getting the exemption right took two runs: the token set has THREE sources and a set built from the consumer table and the native sites alone still refused the preset's. The gate then found two rows my own census missed, both preset rows binding a bundle rather than a module: `trunk-based-preset` and `mise-preset` are each the sole raiser of one class and now carry it. It reports every violation rather than the first, because a migration is what it fires on and one-at-a-time turns a single reading into N builds.

The gate I just wrote refuses the config until the two rows carry their class tokens, so the branch is unbuildable without this write. Admits-answer-precondition: No surface can express this change: `config read first` reads batten.toml and `patch run first` restores it, and neither writes. The collapse predicate this branch adds refused two rows at load — `branch table missing` and `task table missing` are each the sole raiser of one class — and the only fix the gate accepts is renaming those rows in the authority. The write is a reviewed diff in the PR closing CLOUD-1638. Admits-answer-rejected-route: I rejected `patch run first`: restoring batten.toml reverts the migration rather than completing it. `config read first` does not apply — I have already read it, and reading is what produced the census that found these two rows; it leaves both unrenamed and the gate still refusing.
The line arm and the tests the other three arms owe. LINE. A collapsed row renders one token: where the row IS its class's sole raiser the two names are one, and `validate` refuses any other spelling at load, so appending the id would print the same three words twice. The 116 rows that are not collapsed still carry it — for them it is the only discriminator. Decided from the strings rather than a flag, because the load-time predicate has already made them equal exactly when they name one thing. `//MUTANT identity-arm-dropped` sits on the collapse arm — in `policy.rs`, where the behaviour is, rather than in `verdict.rs` where the issue guessed it would be. This enrols `engine-policy` in `$MUTANT_GATES`. THE MUTANT IS PROVEN CAUGHT, and the first attempt to prove it was vacuous: the marker line embeds its own sed pattern, so a naive replace hit the comment and the tree was never mutated — the case passed on clean source and the marker would have shipped as decoration. Re-applied at the code site only, confirmed the declared case fails, reverted. Four cases in `rules_drift.rs`, the declared suite: a sole raiser whose id differs is refused; one carrying its class token loads (without which the first passes over a predicate that refuses every policy row); a word no slot declares is refused; a hyphen-spelled id is the same row as the space form, so normalisation is asserted at the LOAD path and not only under it. The fixture took three corrections worth recording, each a real property: every declared word must be spent by some name, every name must be spelled from declared words — including the ROUTE id, which needs `config` and `first` — and a module may only read an emitted `input.tree` key. The spelling table asserts the ORDER, not the figures. Absolute means drift with the table's contents and would make it a snapshot nobody can update honestly; space < snake < hyphen is the property the canonical form rests on, recomputed from the committed table on every run. Schemas regenerate to no change: the id grammar is a constraint on a value, not a change to a shape. Refs: CLOUD-1638
The migration's fallout, and each item is a place a rule id lives that the
first pass did not reach. 431 failures at the start of this, 0 at the end.
**Test expectations.** 521 lines across 128 suites assert on the emitted id.
Rewritten structurally, excluding two contexts the first attempt got wrong:
a `policy/<id>.rego` PATH is a filename, not an id — the naive pass turned
`include_str!("policy/validator-verdict-clean.rego")` into a path with spaces
in it — and `PRESET_SCOPES` lists preset DIRECTORIES, so `shell-hygiene` there
is a preset name that survived a rename of the row that enables it.
**Two arms were scoped, and both scopings are the same exemption.**
Normalisation and the collapse predicate applied to every config the engine
loads, including fixtures that never adopted the grammar. A tree declaring no
vocabulary spells its ids however it likes — `no-todo` is that consumer's whole
name for the row, not a spelling of a three-word one — so rewriting it renamed
a row nobody asked to rename (22 cases), and refusing it demanded a fixture
name itself after a class it invented (49 cases). Collapse is now scoped to
rows already in the grammar: it decides WHICH of two grammar names a row
carries, and a row with one name is not in that conversation. Not a hole —
`validate_tables` refuses a non-grammar id outright once a vocabulary is
declared, so the arms compose.
**Surfaces the structural pass missed**: the shipped `batten.example.toml` and
`starter.toml`, the built-in `default_rules()` the zero-config path serves, a
`resolve.rs` fixture that redefines the default rule to prove the clamp fires,
and `rules/{scanning,commits,README}.md`, which name rules by id as pointers.
**Two assertions changed shape rather than value.** Both recovered the id by
taking the last WHITESPACE token of the head, which is now one word of three.
The head is `<class> <pointers> <rule-id>` with the id present only when it
differs, so the last three words are the id on a discriminating row and the
first three are on a collapsed one, where the class IS the id.
**One assertion lost a property and got it back through the hop.**
`todo_promotion` asserted `text.contains("ready")` and passed because the row
was called `a-todo-promotion-owes-a-ready-verdict` — prose inside an id. A
vocabulary id cannot carry an arbitrary state name, which is this row's point
rather than a regression, so the assertion now reads it from `policy rule`,
proving the dereference works instead of assuming it.
Golden snapshots regenerated, never hand-edited.

…test ids Two things the slow tier caught that the commit hook skips. `policy-test` failed on four module tests asserting `v.rule == "<old-id>"` — `ancestry-decides-nothing`, `module-layering` and `spawn-adapters` (twice). A module's own tests name the row that raises the finding, so they are a migration surface like any other. `lint:clippy` had `load` at 115/100 once the per-rule class map landed in it. Two extractions, both at seams the function already had: `record_raised` is the record both arms of the loop owe — the union in `emitted` answers "is every declared class raised" and `per_rule` answers how many classes ONE row raises, which a merged set cannot give back — and `collidable_tokens` is the set a rule id could clash with, excluding retired classes because a tombstone is not a name in use. Worth recording: three earlier attempts at this reported an unchanged 115. The edits had not landed — a mutating script was chained with the long `lint:clippy` run in one backgrounded call, so the script's AssertionError went to a log nobody read while clippy ran on unmodified source. Verify the edit, then run the gate; never in one breath. Refs: CLOUD-1638
The second half of the grammar arm. A module's `"rule":` is a FINDING name,
not the `[[rule]]` row id — `run-shape.rego` declares five under one row — and
it is what the emitted line and `policy rule` carry, so migrating the row ids
alone left half the names a reader meets as free-text kebab.
136 finding ids across 74 modules. SEVENTY-FIVE NAME THEMSELVES: a finding
that solely raises one class takes that class's token, which is the collapse
rule one level down. The other 25 are chosen, and nine of them had to be — the
`sbom-*` findings share three classes between them, so no collapse is
available and each needs its own name.
THE GATE, or the rename is half a change. `check_finding_ids` runs at load,
over the module SOURCE. Three readers were wrong before this one:
- `Bundle::declared` is read back from the engine and is not a clean list —
`module-layering`'s `forbidden["rules"] contains "hook"` surfaces `hook`
there, so holding that set to the grammar refused a name no reader meets;
- matching `rules contains` anywhere hit `named_rules contains` in
`rules-drift.rego` and took `path` out of its body;
- `"rule":` is also a fixture KEY — `{"rule": [{"id": "r", …}]}` is the
consumer's table as test input — so the value must be a string.
Checked at load and never on the hot path: this is a property of the
declaration, so `hook` passes `words: None` and says so.
`Resolved` now carries `[vocabulary]`, registered AUTHORITY-ONLY for
`verdict`'s reason one level sharper: these are the words every class token
and rule id is spelled from, so a local row would not add a name, it would
change which names are sayable. Without the field the gate could not fire on
the surface that actually loads modules — `check` and `enforce` resolve before
they load, so a gate reading only `Config` would be one no real run reaches.
The hand-rolled construction sites collapse into `Vocabulary::from`, which is
also what got `run_recorded` back under its line budget.
Two exemptions, both inherited rather than invented: a consumer declaring no
vocabulary is not held to it, and an id that IS a class token is governed by
the class registry — a vendored preset may spell a word no consumer declares,
which is how `trunk push forced` refused itself twice before this landed.
Schemas regenerated for the new key; `config-lint` and all 36 `config_schema`
cases green.

Admits-answer-lost: The grammar arm covers 136 row ids and stops short of the 136 finding ids the same section puts in scope, so the gate would ship looking complete while covering half the names a reader actually meets on a refusal line.
Admits-answer-precondition: No surface can express this change. `config read first` reads batten.toml and `patch run first` restores it; neither writes. The finding-id half of CLOUD-1638's grammar arm renames the `[[waiver]] rule` entries that name a module finding, and `taplo` reformatted the table it sits in — both are writes to the authority that only a write can make. The diff is reviewed in the PR closing CLOUD-1638.
Admits-answer-rejected-route: I rejected `patch run first`: restoring batten.toml reverts the migration rather than completing it, and leaves the waiver rows naming ids no module declares any more. `config read first` does not apply — reading is what produced the census that found these rows, and it changes nothing.
…es one
The fallout pass, and a dereference the row asked for and the tree did not have.
`policy rule` NOW RESOLVES A FINDING ID. §2 lists "a module's `"rule":`" and
"the argument of `policy rule`" as the same grammar, but the verb resolved
`[[rule]]` rows only — and a `policy` finding is emitted under the MODULE's id,
`test add duplicate`, not the row `test fix duplicate` that binds it. So the
name a reader actually sees on the line dereferenced to nothing, which is the
opposite of this row's premise that an id is a live pointer. It falls back to
the owning row; the row id is tried first, because where the two coincide the
row is the more specific answer.
225 occurrences outside the modules — 172 in tests, 50 in `src`, and prose in
`mise-tasks/sbom.sh` that names two findings as pointers.
FOUR THINGS THAT LOOK LIKE A FINDING ID AND ARE NOT, each caught by a test
rather than by care, and each the same shape as the `perf-assert` slip in the
row-id pass:
- `count = "agent-turn-run"` is a RECORDER VARIANT. Renaming it made the
fixture's config unparseable — `unknown variant`, and the enum still lists
the old name because the enum was right.
- `[[fact]] id = "agent-turn-run"` and `input.facts.extracted["agent-turn-run"]`
are the extracted fact's KEY, paired across the fixture and its module. The
module had it right; the fixture lost the pairing.
- `repo("landing-roster-unguarded")` and `repo("nextest-slow")` are fixture
DIRECTORY names. Renamed, they become paths with spaces in them.
- `policy/<id>.rego` is a filename.
And my own fixture was caught by the gate this row adds: `collapse-probe.rego`
declared a two-word finding id. The gate was right, so the fixture changed
rather than the gate — a fixture exempt from the rule it exercises proves
nothing.

Two findings the slow tier raised, both mine. `test add duplicate` on `rules_drift.rs`: my collapse fixture built its own repo with a second `git init`, copying the three git calls already at the top of the file. `fixture-forks` counts those lines and refuses a new one, and it was right — the two helpers wanted the same thing. Extracted to `init_repo`, so the file now carries ONE init where it carried two. The commit matters as much as the init: `check` resolves its base against a HEAD, so an init-only repo answers could-not-look instead of judging the config under test, which is why the first version of that fixture was quietly weaker than it looked. The bats suites named 25 old ids across 11 files — the same migration surface as the Rust tests, reached by the same structural rewrite. `policy-test` 850/850, `test:bats` 0 failures, `lint:clippy` clean, and the cargo suite green at 5317. AND ONE REVERT. My prose fix in `mise-tasks/sbom.sh` — two comments naming finding ids by their old names — tripped `shell retire other`, the shell moratorium. The gate cannot tell a comment from code and refuses an edit to a governed `mise-tasks/` path, which is its job; the two comments now name ids that no longer exist, and that staleness is the cheaper cost. Recorded on CLOUD-1638 rather than worked around. Refs: CLOUD-1638
The gate change CLOUD-1638 needed, and the owner authorised. THE DEADLOCK. `tests/ntia-check.bats` and `tests/remedy-payload-source.bats` slice the authority with `awk '/^id = "sbom-ntia-conformance"/'`. Putting the rule ids in the three-word grammar breaks eight of their cases, and fixing them trips `shell edit refused` — a class with no override route and no `bypass_env`, whose one admitted edit covers REMOVALS only. So the campaign mandated an edit it was structurally unable to land, which is `only_drops_a_retired_reference`'s own words for why that arm exists. This is the same shape one axis over: there, a deleted path; here, a renamed id. THE NARROWING IS EXACT AND NOT A JUDGEMENT. Every removed line must pair with an added line that is the same bytes either side of ONE span; that span must become an id the authority declares; and what it replaced must not be one. A branch renaming no rule has no admitted rewrite, and an added line with no removed counterpart is refused, so this cannot become a licence to maintain a shell rule in place. NO SUBSTRING ENUMERATION, which is what makes it decidable. The new id is known — the authority declares it — so finding it in the added line fixes the prefix and suffix, and the token it replaced is whatever the removed line carries between the same two. Nothing is guessed, which is the arm the model verdict non-negotiable rule 3 would otherwise forbid. FOUR THINGS WERE WRONG BEFORE IT HELD, and three of them passed their own tests: - `replace` is not a builtin the shipped engine implements, so the body was UNDEFINED rather than false and both negative cases passed vacuously while the positive one failed. `drops_a_retired_name` above already does span surgery with `indexof`/`substring`; this now does the same. - The symmetry check ran the predicate backwards, looking for the OLD token in a line that by construction carries the new one. Asked as "has an origin". - It read `delta["base-lines"]["batten.toml"]`, which the tree surface populates only for the paths this module governs — `mise-tasks/**` and `tests/**`. Undefined on every real tree; green on its own fixture. - And `input.tree.documents` is populated only for a row that names its source, so `shell retire partial` now declares `sources = ["batten.toml"]`. The middle two are the same failure as the first: a gate that cannot fire while reporting that it did. Each was caught by running the real tree, never by the synthetic case. `//MUTANT rename-rewrite-unchecked` disables the not-a-live-id conjunct against `a_rewrite_naming_an_unrenamed_token_is_refused`. `policy-test` 853/853, `batten-check` clean.

The migration renames four rule ids that two frozen bats suites slice by literal, fixing them trips `shell edit refused`, and the arm the owner authorised to admit that fix cannot see the config it must consult.

One line, reviewed in the PR closing CLOUD-1638. Admits-answer-rejected-route: I rejected `patch run first`: restoring batten.toml reverts the migration rather than completing it. `config read first` does not apply — reading is what established that `documents` is unpopulated without this declaration, and it changes nothing.
The rebase brought two arms this branch had never seen. `policy/run-shape.rego` gained `foreground-mise` and `background-redirect`, both hyphenated, and the grammar this branch installs refuses a name that is not exactly three words. Each is renamed to the class it already raises — `task run blocked` and `redirect write unread` — which is the convention every other arm in that module follows: the finding id and its verdict are the same token, and both classes are already declared. `crates/batten/tests/it/agentic_record.rs` was rewritten on main and hand-rolls a `policy::Vocabulary`. That struct gained `words` on this branch, so the literal no longer compiles; it takes `None`, matching every other test helper that replays one module rather than the committed table.
… too `policy/run-shape.rego`'s own cases still asserted `v.rule ==` the hyphenated names, and `policy/ci-cache-declared.rego` gained a case on main asserting `read-family-has-a-warm-writer`, which this branch renamed to `job read empty` — four `policy test` failures, all of them a stale assertion rather than a changed decision. The prose mentions move with them. A backticked `foreground-mise` in AGENTS.md, `batten.toml`, `verdict.rs` and four test files now names an id no surface declares, which is the drift this migration exists to remove; the fixture DIRECTORY names keep their spelling, because a directory is not a name in the grammar.

Admits-answer-precondition: No surface can express this change: `batten.toml` carries the [[rule]] and [[verdict]] tables as prose comments that name findings by id, and main added `foreground-mise` and `background-redirect` under this branch. The grammar this branch installs refuses a name that is not exactly three words, so two backticked mentions in the authority's own commentary now point at ids no surface declares. The edit is two token substitutions inside comment prose, visible in the diff it lands in. Admits-answer-rejected-route: `config read first` does not apply: this is not a read that skipped the authority, it is a write to it. `patch run first` does not apply either: it addresses a patch applied before the config was consulted, and here the config IS the subject, with the whole change computed from the ids the same file declares.
`arm-self-authorized` refuses a commit that both declares a `[rule.conserves]` arm and spends it. The arm sets come from the config at the commit and at its PARENT, and `conserves_arms` read a parse failure as an empty map — so an unparseable parent made every arm the head declares look INTRODUCED, and the clause fabricated a refusal over a commit that added nothing. THE FUNCTION'S OWN DOC ALREADY SAID SO. Its third section states that a parent revision which will not parse is could-not-look about the comparison rather than a verdict on the commit; the code returned a verdict. An empty map is a comparison the caller can complete, and the two were conflated. `None` is the distinction. MEASURED ON THIS BRANCH, not imagined. This binary refuses a rule id that is not three words, which is what CLOUD-1638 installs; every config predating that grammar is therefore unparseable to it, and `commit-check` walks exactly that history. `b69bd7a3` was refused for `bats count dropped.changed` — an arm whose token, table and `declared_in` are byte-identical either side of the rename it made. The rename half was already handled: the map is keyed by the TOKEN for this exact reason, and that section anticipated a renamed rule. Only the parse failure was not. The premise case still refuses, which is what keeps the four admitting cases from being satisfied by a clause that never fires. `//MUTANT unparseable-parent-reads-empty` restores the empty-map reading against `a_commit_whose_parent_config_cannot_be_parsed_is_unjudged`.

A refusal line carries two names — the three-word class token and the rule id
beside it. The class is drawn from a 153-word vocabulary in three typed slots;
the rule id is unconstrained kebab prose (
rules.rschecks uniqueness andnothing else), costing 4.93 tokens mean against the class's 3.01. This puts
both names in one grammar, and collapses them to one name where they name one
thing.
The census was counted in the wrong direction, and the collapse arm as filed is unsatisfiable
Measured before any code was written, against
mainatc179129d. The row'sWhy block says "180 classes are raised this way, 174 by exactly one
module" and concludes "for 174 rules the id and the class name one thing."
Those are opposite directions: a class having one raiser does not make that
raiser have one class.
[[rule]]rowspolicyrowspolicyrowci-parityis the sole raiser of 21 distinct classes;shell-retirementof 13;
lock-completeof 10. §2's "validaterefuses a sole raiser whose iddiffers from its class" would demand
ci-paritycarry 21 different ids atonce. No tree satisfies it.
Corrected predicate, and it is a property of the pair in both directions:
Satisfiable, decidable from the config plus the modules, and structural in the
way the original intended — 20 rows collapse, 116 keep a distinct
three-word id. The saving is smaller than the row assumed and the honest figure
is recorded on the row rather than discovered at load.
