…nd the fork's open half is declared
`std.types` names one spelling for two carriers. A TYPE position takes the
`container_template_alias_rows` hop on to the target inhabitant row and lowers
`Set<T>` to `im::OrdSet<T>`; a RECORD-LITERAL position takes the
`container_template_algebra` hop and stops at the modeled algebra struct,
`Rc<PointwisePower<_>>`. Where one compiled closure holds both, the two meet as
a rustc refusal -- 27 of the 331 blocks on the 03_ingest board, in two shapes:
17 E0560 (the algebra name leaking as a Rust type at a construction site) and
10 E0609 (the carrier's own field read off the realized type).
Per the standing ruling "decompose, do not choose": `Set` names the finite
collection, and the predicate keeps its own authority under its own name. Every
corpus site in src/v2 that constructs by characteristic function or reads
`.member` now names `std.algebra` `PointwisePower` directly -- 37 literals, 26
`.member` consumers, 128 occurrences across 20 files. All 37 literals were read
individually and all 37 are characteristic functions; none was a finite
enumeration mis-spelled. Nothing in the finite-`Set` population moved
(`std.graph` `visited`, `std.authorization_profile` `EnumeratedAudience.members`,
`std.syllogism`, `std.occurrence_binding_candidates`, `gunbc.package_delivery`,
the `dag/`-rooted emit templates): every one of those is fed by `empty_set` /
`set_insert` and read by `set_contains`, never by `member`.
WHAT THIS DOES NOT DO, declared rather than left to be rediscovered. The alias
row itself still reads `type Set<element> = PointwisePower<element>`, so
`Set { member: .. }` is still writable and nothing refuses a new one -- the class
sits at MITIGATABLE (DESIGN 4b), not at a wall. The retarget that would make it
unwritable is a `std` authority change whose only verification is a whole-corpus
compile, and it has to move together with the Map row, whose 145 literals are
untouched here. The obligation and its next-rung trigger are recorded on the
declaration itself, in the annotation above `type Set` in `dag/std/types.dag`.
That leaves the 9 `Map { lookup: .. }` blocks of the 27 open; the 18 Set-shaped
ones close.
Measured: `gunbc compile --entry src/v2/compiler/03_ingest.dag --source-root dag
--source-root src/v2` runs frontend, normalize, reconcile and analyses to
completion and reports 52 hard diagnostics, none of which names `Set`,
`PointwisePower` or `member` -- all 52 are the pre-existing source-annotation
class in `dag/test/manual/command_runner_local_argv_receipt_test.dag`, which this
change does not touch. The emitted-block count is NOT re-measured here: "18 of 27
close" is derived from the site-to-literal correspondence, and is a prediction
about the next board rather than a measurement of one.

…d if-chain classification decomposition_scope.md flagged its 97-delegate row as the one number a full read could move. It moves: 78 of 87 resolved delegate bodies never compare the key, within two levels -- they are total functions of the key, not tables. Only 6 branch on the key directly and 3 one level down; the sample that produced the if-chain reading landed on program_facts_lookup, one of the 6. Consequence for the Map lane: most of the population wants the same move this PR made on the Set side (name PartialFunction under its own authority), not 145 re-authorings into finite maps. Stated as a lower bound on openness, with the convergence evidence and the 5 unresolved names declared rather than absorbed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…ric retype
The addendum as first written said the 78 open delegates should name
PartialFunction "exactly the move this change made on the Set side". That is
wrong, and it is the premise a reader would plan the Map lane against, so it is
corrected in place rather than left standing.
PointwisePower is ONE template row, which is why an open characteristic function
inhabits it completely. PartialFunction is THIRTEEN -- it bundles a partial
function with a finite map, and an open delegate cannot answer map_keys,
map_values or count at all. Measured: 0 of the 145 Map{..} literals in the corpus
supply any field beyond lookup, so the other twelve rows are promises the whole
existing population already fails to keep.
The missing carrier is on the Map side, and it already has a peer:
v2.std.collection TotalMap<K, V> { lookup: fn(K) -> V }. The partial peer is
lookup: fn(K) -> V?, so this is the totality axis on an existing pair rather
than a minted name.
Raised by smart-ram-730 against the first revision; verified here from the
profile rosters and the literal population rather than accepted.

…erivation can see it quiet-pike-368 declared a residue in their use-line derivation: the producer walks SIGNATURE-level type positions (type_annotation, params, inferred return), so a name that reaches emitted text only through a value-position body construction is never proposed as a use-line. Checked my own 20 re-typed files against that boundary rather than assuming they clear it: 19 carry the name in a signature position, and exactly one did not -- v2.test.claim.grammar.validate_grammar had 8 PointwisePower literals and 0 signature positions. This is not a class my change introduced (the file's previous `Set` reference was literal-only in the same way, and neither name is on the 7-name hardcoded roster in emit_faithful_text_carrier_import_lines), and the file is not in the 03_ingest closure, so no board site is involved. Fixed anyway because it is cheap and it removes the one site of mine that falls in a declared gap. The two singleton predicates every fixture built inline are now named helpers with declared return types -- 8 literals become 2, and the reference moves into a position the derivation walks. Better modeling independent of the emitter: the same value was being constructed four times. Measured: gunbc compile on BOTH this entry and src/v2/compiler/03_ingest.dag reports 52 hard diagnostics each, zero of which name PointwisePower, PartialFunction, `Set<` or a missing `member` field. 52 is the unchanged pre-existing source-annotation count in dag/test/manual/command_runner_local_argv_receipt_test.dag.

…ses at the finite carriers
One spelling meant two concepts on both the Set and the Map side, and the
carriers disagreed with their own realizations. This is the authority transition
that ends it, in one motion.
WHAT WAS WRONG, measured rather than argued:
- PartialFunction bundled a partial function (lookup) with a finite map
(map_keys, map_values, size, insert, merge). 0 of the 145 Map{..} literals in
the corpus supply any field beyond lookup, so the other twelve rows were
promises the whole existing population already failed to keep.
- The finite-SET concept had a realization row and a 13-template roster but no
type, because it was filed under BooleanAlgebra -- whose type is
{ meet join complement top bottom } and whose only construction in the corpus
is v2.std.logic bool_boolean_algebra, a genuine Boolean algebra over Bool.
All four languages that carry an inhabitant row file a finite-set CONTAINER
under that name: rust BTreeSet<{0}>, go map[{0}]struct{}, python set[{0}],
typescript Set<{0}>. Not one is a lattice.
- A SECOND FINDING, not merely the mechanism that made this cheap: the rust
roster's "BooleanAlgebra" and "PointwisePower" rows were byte-identical --
two algebra names resolving to one realization with nothing saying which is
which, a section 3 duplicate.
WHAT THIS DOES: PartialFunction keeps lookup alone; FinitelySupportedFunction
takes the enumeration surface; FinitePowerSet takes the finite-set concept out
from under the lattice's name (the lattice keeps its name, type and construction
site untouched); Set and Map alias the two finite carriers; TotalMap and
TotalPolicy move from v2.std.collection into the family they belong to.
A correctness repair falls out: algebra_profile_to_dimension answered
CollectionFold for PartialFunctionProfile and none for PointwisePowerCollection --
the same distinction decided two ways, because one name carried an open function
and a finite table. The two open profiles now agree, and the two finite ones do.
RUNG: STILL MITIGATABLE, stated on the declaration. This does NOT make the bad
literal unwritable -- a finite set answers member and a finite map answers lookup,
so both literals still typecheck, and they must, because 145 of them are live. The
invalid state is a literal supplying ONLY those on a carrier promising enumeration,
which is a construction-COMPLETENESS question record literals do not enforce. The
real next-rung trigger is field-completeness on record construction.

review 55220 (REQUEST_CHANGES) is correct and the finding is mine. The previous commit added TotalMap and TotalPolicy to dag/std/algebra.dag under a comment reading "MOVED HERE from v2.std.collection" and never deleted them from v2.std.collection. That is not a move, it is a duplication -- the parallel representation section 3 forbids, landed inside the change whose whole subject is one authority per concept. Worse than untidy, and worth stating at the grain that decides it: name resolution in this substrate is whole-pool, and DESIGN section 4b already records that a census-AMBIGUOUS type name resolves by SILENT LAST-IMPORT-WINS rather than refusing. So two live declarations of one type name is a real ambiguity resolved silently, not a cosmetic duplicate awaiting cleanup. Both declarations now exist once, in std.algebra, beside the family they belong to. Nothing referenced either from v2.std.collection -- both had zero code consumers, which is why the duplicate compiled and why no diagnostic named it.

…it forced smart-ram-730's read of #9059 found a coverage asymmetry here that neither their review nor mine caught in the diff, and the split made it worse in both directions at once. BEFORE this fix, after the split: BooleanAlgebra was still listed while its container inhabitant row had MOVED to FinitePowerSet, so the roster named a lattice as a container; and PartialFunction had been dropped while it still carries a row, silently retiring its coercion coverage at the moment the split gave it real callers. Two errors, opposite signs, one list. The list's only consumer read concat(canonical_container_names(), ["PointwisePower"]) -- a hand-appended name compensating for one the authority omitted. That is the authority being wrong, not the caller being thorough, so completing the list deletes the append rather than leaving a patched call site beside a fixed authority. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…amed it One conflict, in `dag/std/types.dag`. #9055's note declared its own next-rung trigger as "the Map-side decomposition landing, after which both rows retarget in one motion." That is this PR, so the note is superseded rather than merged -- keeping both would leave the file asserting the retarget is pending beside the retarget itself. A prose row is deleted for one reason and takes everything in it unless its contents are enumerated first, so the two facts only #9055's block carried are carried forward explicitly: the fusion measurement (`PointwisePower` inhabiting `BTreeSet<{0}>`, so a declaration position lowered to `im::OrdSet` while a record literal lowered to the algebra struct, meeting as a rustc refusal wherever one compiled closure held both) and that the predicate half is closed -- no `Set { member: .. }` literal survives in `src/v2`.
`claim_executor --required-regen` refused on this branch:
`first_generation_equal=false`, `planned=133 executed=133`, `FAIL generated
surface drift` naming ten mirrors -- `extdeps_languages_{go,python,rust}_types.rs`,
`std_algebra.rs`, `std_computation.rs`, `std_types.rs`, and
`v1_compiler_{coercion,emit_rust,infer_types,trait_derive_emit}.rs`. Every one
is a file this PR edited. These are the emitter's own candidates installed
unmodified; a hand-edited mirror is the one thing the gate exists to refuse.
The reviewer predicted this from `std_algebra.rs` still carrying the
full-field `PartialFunction` mirror, and asked for the gate to be confirmed
green before merge. It was not green; it is the reason to have asked.
Byte-verified off the remote runner: the dispatch printed TGZ_BYTES=242026 and
a sha256 prefix of the archive it built, and the locally decoded archive
reproduces both. The same ten files regenerated from the child branch are
byte-identical to these, which is the expected result and worth stating -- the
mirrors are a function of `dag/` and `src/v1`, and the child's additional
changes are confined to `src/v2`, which is not mirrored.
Installing round one's ten candidates changed the input to the next emit, so a second round drifts two more. `compiler_tests.rs` picks up the coercion assertions for the new names -- `FinitePowerSet` and `FinitelySupportedFunction` gain rows, `BooleanAlgebra` loses its, and the `PointwisePower`/`Set` pair reorders as `canonical_container_names` now orders them. `std_types.rs` drops `pub use crate::std_algebra::PartialFunction;`, which follows from `dag/std/types.dag` no longer importing that name after the alias retarget. Taken from the child branch, where the same two rounds were run and the third returned `first_generation_equal=true`. That the two branches produce identical mirrors is expected -- they are a function of `dag/` and `src/v1`, and the child's extra changes are confined to `src/v2` -- and it was measured for round one rather than argued (all ten byte-identical). This branch's own regen is re-run after this commit to confirm it for round two as well, because the argument and the measurement are not the same thing.
… had no method surface CI's floor phase refused on the child branch with: src/v2/lens/structural_resolution.dag:20:40: error: method 'lookup' cannot be resolved: receiver type 'Node(std.algebra.PartialFunction)' establishes no method surface, so the method's existence is not established and no declared frontier row admits it `kernel_algebra_profile_value` keyed seven names -- Int, Float, Bool, String, List, SET, MAP. Every one an alias spelling; no carrier name anywhere. `kernel_profile_lookup` is what `04_infer`'s method-existence wall consults to decide whether a receiver has a declared surface at all, so `tree.facts .lookup(node)` refused on a `PartialFunction` receiver while the byte-identical call on a `Map` receiver resolved. One concept, two answers, decided by which of two spellings for it the author happened to write: the §3 fork with nothing else in it. THIS PR DID NOT INTRODUCE IT, IT MADE IT REACHABLE, and the fix belongs here rather than downstream for that reason: this is the change that makes the carrier names the ones declarations write. Land it without these rows and main holds carriers whose method surface is undecided, with the repair handed to whoever next writes a method call on one and gets that diagnostic with no context. The three rows point each carrier at THE PROFILE IT ALREADY HAS -- `PartialFunctionProfile`, `FinitelySupportedFunctionProfile` and `FinitePowerSetProfile` are declared in this file, their template rosters are declared in this file, and `algebra_templates_for_profile` already dispatches to them. Nothing here is a new claim about what those carriers can do; it is the existing algebra answering to the carrier's real name. `PointwisePower` is deliberately not added, and the code says so. Its 80 declaration positions predate this lane, and the risk is narrow but real: the frontier roster admits undecided calls keyed on (module, method, RECEIVER SHAPE), so a call admitted today is admitted BECAUSE its receiver has no surface -- give it one and the admitting row stops matching. That is a measurement, not a guess, and the row will carry the number rather than the argument. WHY THE COMPILE BOARD DID NOT SEE THIS, since I cited it three times as evidence this stack was sound: `gunbc compile --entry src/v2/compiler/03_ingest .dag --target rust` reports 0 blocking on this exact tree. It resolves one entry's import closure. `04_infer`'s own note names the whole-corpus instrument as `gunbc compile --source-root dag --source-root src/v2 --target dag`, and records the identical trap: a narrow instrument reporting clean is indistinguishable from a wall that works.
…ure whether it reds anything Discriminator for the residue note on #9059. If the floor's refusal count is unchanged against the 3-row tree, the stated risk (a frontier row admitting an undecided PointwisePower call stops matching once the receiver gains a surface) is not realised in this corpus and the residue closes. If refusals appear, the residue is justified by a number instead of an argument. Either way the note carries the measurement, not the reasoning.

review 55377 is right and its remedy is already the plan — recording that here rather than leaving it unanswered. This branch exists to be run, not landed. It is #9059 plus one withheld row, and its floor result against #9059's is a discriminator I could not obtain any other way: It is ready rather than draft for one reason: draft skips CI, which is the entire point of the branch. It goes back to draft or closed the moment the result is read, exactly as the review says. Why the measurement matters rather than being idle curiosity: #9059 adds profile rows for three carriers and deliberately withholds

…er without it The previous commit added three rows to `kernel_algebra_profile_value` in `dag/std/algebra.dag` and CI's floor refused with the byte-identical error it refused with before. The reason is two phases earlier in the same ledger: required-ci: regen FAIL generated surface drift: std_algebra.rs ... required-ci: floor refused: ... 'Node(std.algebra.PartialFunction)' establishes no method surface The typechecker that refuses is the SEED BINARY, built from `src/v1/stage0/src/std_algebra.rs`. That mirror still carried the seven-key map, because a `.dag` edit reaches an artifact only through regen. The fix was correct and had not arrived. This installs the emitter's own candidate (`std_algebra.rs` alone, byte- verified off the runner: 6564 bytes, sha256 prefix df223a4e928cf630, both reproduced locally after decode). WORTH RECORDING BECAUSE THE LEDGER GOT IT RIGHT AND I ALMOST DID NOT. The regen line named the file seventeen minutes before the floor refused for exactly that reason, and the two failures in one ledger are what make the diagnosis available: a line-stopping regen would have shown the drift and hidden the floor error, leaving one fact instead of the relation between two. The independent-phases design is what turned "the fix did not work" into "the fix has not arrived".

…them deep-ant-102's floor probe hit ctrl-build's 45-minute default cap mid-floor and ctrl-build surfaced it as exit 0, output ending at their own header. Their grep for probe arms would have returned EMPTY -- and empty is finding-shaped here: three of their four pre-registered predictions were absences (declined_live +0, arm4 invisible, zero test data planned), so a run that never executed would have appeared to confirm them. The general shape: an absence-shaped prediction is confirmed by the absence of the experiment. This is the form where the signal answers exactly the question asked, correctly, about a universe that does not exist. The liveness control (arm5) was added to catch a harness that runs and evaluates nothing. It happens to be the only PRESENCE prediction in the set and therefore the only one a dead harness cannot satisfy. That is the design rule: a pre-registration made mostly of absences needs at least one presence prediction, or the experiment cannot fail in a way anyone notices. Count the moods before running. Marker rule gains its final clause: trap 11 said anchor to a whole line; this adds plant it AFTER the subject, not only before. A header proves the dispatch started; only a trailing marker proves the subject finished. Pairs with silent-gull-867's #9103 false negative as the two ways a run agrees with you for the wrong reason -- the treatment never reached the instrument, and the instrument never reached the subject. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
MARKER_MIRROR_PP_BEFORE=0 -- the PointwisePower row was in `dag/std/algebra.dag` and NOT in `src/v1/stage0/src/std_algebra.rs`, so the seed binary that runs the floor carried the control's profile map. This branch would have returned a floor result identical to #9059's for a reason having nothing to do with PointwisePower. That is the worst possible outcome for this particular branch rather than a generic staleness bug. The pre-registration says "unchanged -> the risk is not realised and the residue closes", and a stale binary hands back exactly that string. The probe exists to stop an argument shipping as a fact, and it would have supplied the argument's conclusion with no error anywhere: run succeeds, numbers internally consistent, control and treatment agree. Emitter's own candidate, byte-verified off the runner: 6581 bytes, sha256 prefix 38dde84f69a3ab55c83f58839174cd09, both reproduced locally after decode. 6581 rather than #9059's 6564 is the seventeen bytes of the row itself, which is the cheapest available confirmation that the two mirrors differ by exactly the treatment.

…ud sibling silent-gull-867 corrected the credit this brief gave them, and the correction is its most useful fact. I had written that they saw the #9103 false negative before running it, implying suspicion did the work. It did not: they hit the same staleness on #9076 where it failed LOUDLY -- the floor refusing with an unchanged error while regen named the file -- and only then asked whether the probe cut from that head shared the cause. Nothing about #9103 in isolation would have prompted the check, and its own pre-registration would have discouraged one: 'unchanged -> risk not realised' is an instruction to accept exactly the string a stale binary produces. So the detection route is: a sibling sharing the cause failed loudly and the author generalised. That is not a method -- it needs a loud sibling to exist, be noticed, be diagnosed correctly, and be recognised as sharing a cause with something that has not failed. Four conditions, none under the author's control. Practical consequence for the repair: you cannot catch this after the fact. Every other member announces itself eventually; the silent member's only tell is a confirmation you were already expecting. The property must be enforced BEFORE measurement, which puts the repair at commit or dispatch time rather than in anyone's reading discipline. Also records the confirmation by measurement (MARKER_MIRROR_PP_BEFORE=0) and the 17-byte mirror delta as cheap evidence the two mirrors differ by exactly the treatment.

Measurement only, for the residue note on #9059. Draft, never to merge — I close it once CI reports.
#9059 adds profile rows for
PartialFunction,FinitelySupportedFunctionandFinitePowerSetand deliberately withholdsPointwisePower. The stated reason is thatunresolved_method_frontieradmits undecided calls keyed on (module, method, receiver shape), so a PointwisePower call admitted today is admitted because its receiver has no surface — give it one and the admitting row stops matching, and any method absent frompointwise_power_collection_templateslands as a hardMethodNotFound.That is an argument, not a measurement, and a residue note asserting an unestablished consequence is exactly what this lane has spent the night refusing to ship. This branch is #9059 plus the one withheld row. Its floor result against #9059's is the discriminator.
