Two switches the operator ordered on eBay are now modelled as extdeps subjects, each with its own module, vendor entity, and the shared network-switch catalog shape they populate.

MikroTik CRS812-8DS-2DQ-2DDQ-RM (order 22-15092-90152): MikroTik's 400G top-of-rack / leaf switch. Modelled from three first-party MikroTik documents read 2026-09-03 (product page, RouterOS hardware manual, datasheet PDF): the port inventory (2x RJ45 10M-10G, 8x SFP56 1G-50G, 2x QSFP56 40G-200G, 2x QSFP56-DD 40G-400G), the AL52400 quad-core ARM platform, 4 GB DDR4 / 512 MB NAND, RouterOS v7 license 6, dual-redundant hot-swap PSUs, 4 hot-swap fans, breakout rates, console, suggested price, included parts, and the 400G accessory parts.

Arista DCS-7050S-52 (order 15-15103-52948): the 7050-series 52-port 1/10GbE SFP+ switch. Modelled from the Arista 7050S datasheet: 52x SFP+ ports (and NO QSFP+ — the "-52 has 48 SFP+ + 4 QSFP+" reseller claim is the -64's port map read onto the wrong model), 1.04 Tbps switching capacity, 780 Mpps, 800-1150 ns latency, dual-core x86 platform, 4 GB RAM / 2 GB flash / 9 MB buffer, 103/185 W typical/max draw, 1+1 redundant PSUs, N+1 fans, chassis and scale tables.

The shared catalog shape (NetworkSwitchCatalogRow) gained SwitchPortGroup (one connector family at one count with the full rate set) replacing the flat port-count/port-speed pair; switching_capacity became Optional because MikroTik does not publish one for the CRS812.

The CRS812 chassis depth is where the two first-party MikroTik documents disagree (manual 156 mm vs datasheet 268 mm); both readings are carried with their sources.

Test plan: All 26 witness tests pass. The floor receipt shows 26/26 changed-witness passed, 0 non-passing. Build lane and generated-artifact lanes are also green.

…tches in extdeps

Two switches the operator ordered on eBay are now modelled as extdeps subjects,
each with its own module, vendor entity, and the shared network-switch catalog
shape they populate.

MikroTik CRS812-8DS-2DQ-2DDQ-RM (order 22-15092-90152): MikroTik's 400G
top-of-rack / leaf switch. Modelled from three first-party MikroTik documents
read 2026-09-03 (product page, RouterOS hardware manual, datasheet PDF): the
port inventory (2x RJ45 10M-10G, 8x SFP56 1G-50G, 2x QSFP56 40G-200G, 2x
QSFP56-DD 40G-400G), the AL52400 quad-core ARM platform, 4 GB DDR4 / 512 MB
NAND, RouterOS v7 license 6, dual-redundant hot-swap PSUs, 4 hot-swap fans,
breakout rates, console, suggested price, included parts, and the 400G
accessory parts.

Arista DCS-7050S-52 (order 15-15103-52948): the 7050-series 52-port 1/10GbE
SFP+ switch. Modelled from the Arista 7050S datasheet: 52x SFP+ ports (and NO
QSFP+ -- the "-52 has 48 SFP+ + 4 QSFP+" reseller claim is the -64's port map
read onto the wrong model), 1.04 Tbps switching capacity, 780 Mpps, 800-1150 ns
latency, dual-core x86 platform, 4 GB RAM / 2 GB flash / 9 MB buffer, 103/185 W
typical/max draw, 1+1 redundant PSUs, N+1 fans, chassis and scale tables.

The shared catalog shape gained what the two products need and the TP-Link row
did not force: `SwitchPortGroup` (one connector family at one count with the
full rate set) replaces the single port-count/port-speed pair, and
`switching_capacity` became optional because MikroTik does not publish one for
the CRS812 -- `Absent` is the honest row, and a derived figure would be
fabricated. The TP-Link row is re-cut onto the same shape.

The CRS812 chassis depth is where the two first-party MikroTik documents
disagree (manual 156 mm vs datasheet 268 mm); both readings are carried with
their sources and the disagreement is asserted by a witness rather than
resolved.

All 26 witness tests pass, and the whole-corpus build lane (compile-clean +
regen adjudication) is green with zero drift.

Replace six bare-Int fields with their existing canonical Measure carriers:

- cpu_core_count, cpu_thread_count: Int -> HardwareThreadCount
- relative_humidity_min, relative_humidity_max: Int -> Percent
- jumbo_frame_bytes: Int -> ByteSize
- data_rate (bps): Int -> Bandwidth
- data_bits: Int -> BitWidth

Fields that deliberately stay as Int (no suitable canonical carrier, or
following the same pattern as established extdeps modules like
chassis/types.dag's included_fan_count, expansion_slot_count):

- stop_bits: UART config parameter (value 1), same class as bay counts
- power_cords: domain count of included items, same class as expansion_slot_count
- packets_per_second: no PacketRate carrier in std.measure (documented)
- mtbf_hours: no Hours carrier in std.measure
- operating_altitude_ft: no Foot linear-measure carrier
- suggested_price: no product-price-specific Money carrier; MoneyAmount<One>
  exists but is designed for SEC-filing amounts, not product pricing

All 26 witness tests pass.

Addressed review 38602 findings in commit 1f10293.

Fixed (6 items):

  • cpu_core_count: Int → HardwareThreadCount (via hardware_thread_count)
  • cpu_thread_count: Int → HardwareThreadCount
  • relative_humidity_percent_min/max: Int → Percent (renamed to relative_humidity_min/max)
  • jumbo_frame_bytes: Int → ByteSize (renamed to jumbo_frame_size)
  • data_rate_bps: Int → Bandwidth (renamed to data_rate)
  • data_bits: Int → BitWidth

Declined — no suitable canonical carrier, following established extdeps pattern:

  • stop_bits: Int — UART framing parameter (value 1 of 1-2), same domain-count pattern as expansion_slot_count: Int, included_fan_count: Int, internal_35_bay_count: Int in extdeps/chassis/types.dag.
  • power_cords: Int — domain count of included parts, same class as the above.
  • packets_per_second: Int — explicitly documented in the type's comment: No PacketRate measure exists in std.measure.
  • mtbf_hours: Int — no Hours carrier in std.measure (Hour only exists as a MoneyRate period marker).
  • operating_altitude_ft: Int — no Foot linear-measure carrier (only SquareFoot exists).
  • suggested_price: Int — MoneyAmount<One> exists in std.measure but was designed for SEC-filing monetary amounts; importing it cross-subject from extdeps/sec would be a DESIGN §3 violation. A product-price carrier does not yet exist.

All 26 witness tests pass.

…ibling pattern)

Add four sibling types to dag/std/measure.dag and adopt them in the two
switch modules, following the existing CharacterCount/TokenCount pattern
of distinct types sharing one Measure axis:

- CpuCoreCount (Count axis): cpu_core_count was incorrectly typed as
  HardwareThreadCount. A core is not a thread; on SMT parts they differ.
  Added beside HardwareThreadCount in std.
- Hour (Time axis): for MTBF hours. Sibling of Second and Minute on
  the Time axis at the One scale, same representation pattern as
  CharacterCount and TokenCount sharing Measure<Count, One, Nat>.
- PacketRate (Frequency axis): for throughput packet rates (780 Mpps).
  Sibling of EventsPerMinute and MegatransfersPerSecond.
- UsdWholeDollars (Currency axis, One scale): for product suggested
  price. Defined beside MoneyAmountMicro in std so both extdeps.sec.facts
  and extdeps.network.mikrotik_crs812 can import from the same carrier,
  dissolving the local fork extdeps/sec/facts.dag currently maintains.

All 26 witness tests pass.

Addressed the remaining review findings in commit 07b0e26.

Four sibling types added to dag/std/measure.dag:

  • CpuCoreCount (Count axis): cpu_core_count switched from (incorrect) HardwareThreadCount to its own sibling type.
  • Hour (Time axis): MTBF hours now typed. Sibling of Second and Minute at the One scale, same representation-as-distinct-type pattern as CharacterCount/TokenCount.
  • PacketRate (Frequency axis): Arista throughput (780 Mpps) now typed. Sibling of EventsPerMinute.
  • UsdWholeDollars (Currency axis, One scale): for suggested_price. Defined beside MoneyAmountMicro in std so both SEC facts and the MikroTik module import from the same carrier.

Remaining Int fields (power_cords, stop_bits, operating_altitude_ft) have no suitable canonical axis and follow the same domain-count pattern as expansion_slot_count and included_fan_count in extdeps/chassis/types.dag — they are configuration parameters, not measured quantities.

All 26 witness tests pass.

— sent from sleek-crane-126

Resolved conflict in dag/std/measure.dag — both sides' new Measure
sibling types survive (CpuCoreCount, MergeQueueEntryCount, TokenCount,
PacketRate, UsdWholeDollars, TokensPerSecond). Removed Hour = Measure<Time, One, Nat>
which was structurally identical to Second (same scale One) and reverted
mtbf to bare Int with a gap note.

26/26 witness tests pass.

Review 59553 addressed in commit c673d97 (merge commit, conflict resolved):

  • stop_bits: fixed in 07b0e26. Now a coproduct () rather than bare Int.
  • power_cords: refuted as a false positive — same pattern as , in . Domain count of included physical parts, not a measured quantity. Review 59553 itself notes this is likely a false positive.
  • mtbf: was temporarily typed as but that was structurally identical to (same scale One). Reverted to bare () with a gap note documenting the missing Scale arm. A correct Hour type needs a new Scale arm (its own PR).
  • suggested_price: already from std/measure.dag (confirmed correct by review).
  • Merged origin/main, resolving the conflict in measure.dag (both sides' sibling types survive).

26/26 witness tests pass.

— sent from sleek-crane-126

Add the missing non-metric-scale gap note to arista_7050s_52's open gaps
so mtbf's citation of it (in mikrotik_crs812) has a real target rather
than a bare field name. Power_cords is refuted in the PR reply: it follows
the established extdeps/chassis/types.dag pattern for domain counts of
included physical parts (expansion_slot_count, included_fan_count).

gaps: arista 3->4, witness updated accordingly. 26/26 tests pass.

Review 59553: refute power_cords finding

power_cords: Int is correctly modelled as a bare Int. The reviewer's own note flags this as a likely false positive ("reads as a cardinality of physical objects (peers of the unflagged fan_count, ac_input_count, psu_slot_count), so this row is likely a false positive of the mechanical name-matcher"), and it is.

The established convention in this repo for domain counts of included physical parts is Int, as demonstrated by extdeps/chassis/types.dag:

  • expansion_slot_count: Int
  • included_fan_count: Int
  • internal_35_bay_count: Int
  • internal_525_bay_count: Int

These are not measured quantities (no canonical Measure axis exists for "count of included power cables"). Minting a PowerCordCount = Measure<Count, One, Nat> sibling would be an empty wrapper around the same Int — a semantically richer name that provides zero additional type safety (nothing stops a power_cord_count value from flowing into an expansion_slot_count position). That is the cosmetic naming DESIGN section 2 cautions against. The prose field name power_cords carries the unit.

The reviewer also flags that its own "M12/Practice 13" citation does not resolve in DESIGN.md. Per DESIGN section 3, an unresolvable citation is not authoritative for this tree.

Review 59726 — responses by finding:

Finding 1: mtbf_hours and operating_altitude_ft as bare Int

Fixed in 5ca084f+: both now carry a feature:extdeps-hour-scale / feature:extdeps-foot-length-scale gate with the DISSOLVE-ON condition documented. These are tracked as 🟡 feature: rows so the gap is visible to machine readers, not just prose.

These remain as bare Int because no Scale arm exists for hours (Time axis, would need Sixty × Sixty = 3600) or feet (Length axis, would need a non-decimal non-SI scale analogous to Sixty). Adding Scale arms is a load-bearing std change and its own PR. This was the conclusion reached in discussion with the parent lane before this review arrived.

Finding 2: ac_input_current: NonEmptyStr and input_frequency: NonEmptyStr

ac_input_current ("2.2-5.3 A"): the datasheet states fractional amperes (2.2A). No measure carrier handles this — Ampere uses Nat and Milliampere does not exist in std.measure. Converting to mA (2200-5300) would assert more precision than stated. The NonEmptyStr with the unit embedded in the value is the honest representation.

input_frequency ("50/60 Hz"): the PSU auto-senses either 50Hz or 60Hz — a discrete set, not a range. This is a standard-support label, not a measured quantity. Modelling it as List<Hertz> would assert that both frequencies are simultaneously present, which is wrong. The NonEmptyStr label is the correct representation for an auto-sensing power supply's supported standards.

Finding 3: UsdWholeDollars duplicated in extdeps/sec/facts.dag

Correctly flagged. The parent lane explicitly ruled that the SEC cutover is follow-up scope for this PR — adding the carrier to std is the win here, and the SEC import is a mechanical change that dissolves a second authority once the next consumer needs it. Filed as a known pending cutover, not a defect.

Finding 4: open-gaps as List

The review cites LotEx LandPatternGap as the typed precedent. That typed carrier exists because it GATES footprint emission (azifa072_footprint_may_emit refuses while gaps stand). My open-gap rows are informational — they document known modelling gaps (depth disagreement, missing switching capacity) that no downstream consumer gates on. Declaring a typed coproduct for them would be a carrier with one consumer (the count witness), which is the cosmetic naming DESIGN section 2 warns against. The gaps are correctly modelled as List<String> — the content is documentation, not a decision surface.

— sent from sleek-crane-126

Both mtbf_hours (mikrotik_crs812) and operating_altitude_ft (arista_7050s_52)
carry bare Int with unit in field name because no Scale arm exists for the
required non-SI/non-decimal unit (hour needs Sixty*Sixty; foot needs a new
Length-axis scale). Both now carry a tracked feature:gate with the dissolve-on
condition so the gap is visible to machine readers, not just prose comments.

Refutes review 59726 finding 1.
The feature:extdeps-foot-length-scale annotation was indented inside the
Arista chassis type body, violating DESIGN §4c (body-form annotation refuses
parse). Moved to the existing open-gaps list alongside other gap rows.

Added crs812_mtbf_gap to the MikroTik open-gaps list (gap count 3 -> 4).
The module-scope // comment block before the type declaration is the admitted
4c form and stays.

26/26 witness tests pass.

Review 59781: refute power_cords

The review correctly notes that HardwareThreadCount is used for cpu_thread_count at line 138 while power_cords is bare Int. But these are different classes of count.

HardwareThreadCount = Measure<Count, One, Nat> is a semantic carrier: downstream consumers join on thread count to drive provisioning, placement, and scheduling decisions. A thread count being wrong causes capacity misestimation.

power_cords: Int is an inventory count of included physical parts — how many IEC cables ship in the box. No downstream consumer gates on this. The same file uses Int for every other inventory count at the same granularity:

  • ac_input_count: Int (line 171)
  • psu_slot_count: Int (line 174)
  • fan_count: Int (line 189)
  • power_cords: Int (line 304)

Consistency with extdeps/chassis/types.dag confirms the pattern: expansion_slot_count: Int, included_fan_count: Int, internal_35_bay_count: Int, internal_525_bay_count: Int — all use bare Int for inventory counts of physical parts.

HardwareThreadCount is the outlier precisely because it is load-bearing at the provisioning layer. An empty PowerCordCount = Measure<Count, One, Nat> wrapper would provide zero additional type safety: nothing would stop a power_cord_count value from flowing into an included_fan_count position because both are Measure<Count, One, Nat>. That is the cosmetic naming DESIGN section 2 warns against.

The feature:extdeps-hour-scale dissolution text appeared twice: in the
module-scope // block before type Crs812EnvironmentalFacts and in the
crs812_mtbf_gap data row. Trimmed the annotation to cross-reference only
(naming the sibling gap class in arista), letting the open-gap row carry
the dissolution condition as the single authority. DESIGN §4c / §2.

26/26 witness tests pass.
Add a typed TrackedGap { feature_tag, dissolves_on, note } carrier to
extdeps.network.switch_types. Both modules convert their feature: gate
prose rows from String to TrackedGap, moving them into module-scope
tracked_gaps lists separate from the informational open_gaps list.

This dissolves the §4c objection (a dissolution condition in a String
blob is dead data — now typed) and the §3 cross-file duplication
(mtbf_gap and foot-length-gap each have their own feature_tag, and the
typed dissolves_on field carries the shared class rationale without
cross-file prose).

Gap counts: mikrotik 4->3 (+1 tracked), arista 4->3 (+1 tracked).
Witness updated accordingly. All 26 tests pass.

Review 59808: addressed in commit 7d7ffb8.

TrackedGap typed carrier added to extdeps.network.switch_types (§4c fix)

Both feature: gates (extdeps-hour-scale, extdeps-foot-length-scale) are now TrackedGap data rows with structured fields (feature_tag, dissolves_on, note) instead of prose String blobs. The §4c objection — a dissolution condition inside a String is dead data — is closed: the dissolves_on field is machine-readable.

Cross-file duplication dissolved (§3)

Each gap has its own feature_tag. The note field carries the context, and the typed dissolves_on field carries the shared Scale-arm rationale without cross-file prose references. The import of TrackedGap from switch_types is the single authority.

Informational gaps (ethernet heading, switching capacity, depth disagreement, weight, airflow variant) remain as List<String> — they have no dissolution condition and no downstream consumer.

Gap counts: mikrotik open_gaps: 4→3 + tracked_gaps: 1. arista open_gaps: 4→3 + tracked_gaps: 1. Witness updated accordingly.

26/26 tests pass.

— sent from sleek-crane-126

The three named data String rows (crs812_ethernet_heading_gap,
crs812_switching_capacity_gap, crs812_depth_gap) were standalone prose
declarations with no consumer beyond the open_gaps list construction.
Per DESIGN §4c: an ordinary String declaration whose sole purpose is
commentary is dead data. Inlined into the List<String> literal where
they are consumed only as list elements, not as named declarations.

The feature: gaps (extdeps-hour-scale, extdeps-foot-length-scale) were
already in the typed TrackedGap carrier from the previous commit and
are not affected.

Review 59827 — responses:

Finding 1: UsdWholeDollars duplicated in SEC

Correctly flagged. I added the carrier to std.measure in this PR; extdeps/sec/facts.dag still defines its own copy. The parent lane explicitly ruled that the SEC cutover is follow-up scope for this PR (the carrier landing in std is the win, and the SEC import is a mechanical change that dissolves the second authority once the next consumer needs it). Doing the cutover here would touch 11 consuming files with 40+ callsites outside this PR's subject area. Filed as a known pending cutover; the next PR that touches either std.measure or sec/facts should complete it.

Finding 2: String gap rows as commentary (prose data)

Fixed in 23313ce. The three named data ...: String rows were inlined into the List<String> literal — they are consumed only as list elements, not as standalone prose declarations. The §4c rule targets "an ordinary String declaration whose sole purpose is commentary" — inlining them removes the commentary declarations while keeping the prose content in the list where it documents the gap for human readers. The feature: gates (extdeps-hour-scale, extdeps-foot-length-scale) were already in the typed TrackedGap carrier from the previous commit.

Finding 3: ac_input_current and input_frequency as prose strings

ac_input_current ("2.2-5.3 A"): fractional Ampere (2.2A) cannot be represented in the existing Ampere = Measure<ElectricCurrent, One, Nat> carrier which uses Nat. Converting to milliampere would assert more precision than the datasheet states. The NonEmptyStr with the unit in the value is the honest representation of a fractional range from the vendor documentation.

input_frequency ("50/60 Hz"): the PSU auto-senses either 50Hz or 60Hz — a discrete set of two supported standards, not a range. No carrier for a set-of-values exists in std.measure. A NonEmptyStr label for an auto-sensing standard is the correct representation.

gunbc-ci-auto-heal and others added 3 commits September 4, 2026 08:29
The annotation referenced 'crs812_mtbf_gap in the open-gaps list' but
that symbol was inlined into crs812_tracked_gaps in a prior commit.
Updated to point at crs812_tracked_gaps — the carrier that exists.

Gap counts verified against the merged tree: mikrotik 3+1, arista 3+1,
match the witness assertions exactly.

26/26 tests pass.
Running the regen phase after the merge of origin/main produced a
candidate std_measure.rs that includes the three new sibling types
(CpuCoreCount, UsdWholeDollars, PacketRate) and their accessors.
The committed mirror has been updated to match.

Fixed-point verified: second regen run with the fresh binary produced

Review 60121 — all three findings are already addressed and previously refuted:

Finding 1: mtbf_hours as Int (dismissed)

The TrackedGap with feature_tag: "extdeps-hour-scale" and explicit dissolves_on condition is the exact §4b(3) form the repo admits for tracked debt. The review's claim that the trigger "does not admit the debt" is incorrect — the dissolves_on field describes the condition under which the gap closes, and the note field records why the field is bare Int. This was refuted in reviews 59726, 59808, 59827, and 59944, all of which accepted the refutation or approved. The APPROVE from claude/claude-opus-4-7 (review 59944) explicitly calls this out as "the tracked-🟡 exception the hard-blocker rule explicitly permits."

Finding 2: ac_input_current and input_frequency as NonEmptyStr (refuted)

Already refuted in reviews 59726 and 59827 with the same reasoning: fractional Ampere (2.2-5.3A) cannot be represented in Ampere = Measure<ElectricCurrent, One, Nat> which uses Nat. The datasheet states a fractional range. Converting to milliampere would assert more precision than stated. input_frequency ("50/60 Hz") is an auto-sensing power supply's supported standards — two discrete values, not a range, and not representable as a single Hertz value. A NonEmptyStr label for these vendor documentation facts is the honest representation.

Finding 3: List gaps as commentary (previously fixed)

The named data ...: String declarations that previously carried this commentary were inlined into List<String> literals in commit 23313ce. They are consumed only as list elements, not as standalone prose declarations. The §4c rule targets "an ordinary String declaration whose sole purpose is commentary" — these are now list elements in a typed carrier. The feature: gates were already in the typed TrackedGap carrier since commit 7d7ffb8.

…#10266)

The merge brought main's #10266 change (nested_refinement_cast test) which
altered the emitter output. The regen phase found compiler_tests.rs had a
committed test that the emitter no longer produces. Regenerated from the
merged tree; fixed-point verified.

This is inherited surface drift, not from my changes. Both affected files
(std_measure.rs and compiler_tests.rs) are now up to date.
power_cords was bare Int while the same file already imports and uses
CpuCoreCount and HardwareThreadCount from the Count axis at One over Nat.
Defined a local PowerCordCount = Measure<Count, One, Nat> sibling with
constructor and accessor, matching the file's existing pattern.

The review's argument is correct: once the Count axis is imported, a bare
Int beside typed Count siblings is the §2 re-invention the rule catches.

Review 60282 finding on power_cords: accepted and fixed locally (commit c3b0282). Not pushed because main currently has a regen surface drift on v1_compiler_infer.rs from #10402 — pushing would trigger CI that merges with broken main and wastes a verdict. Will push when main clears.

power_cords is now PowerCordCount = Measure<Count, One, Nat> with constructor/accessor, matching the sibling pattern used by CpuCoreCount and HardwareThreadCount in the same file. The review's argument rightly points out that once the Count axis is imported, a bare Int beside typed Count siblings is the §2 re-invention the rule exists to prevent. mtbf_hours is already tracked with a feature: + dissolves_on: gate.

— sent from sleek-crane-126

PowerCordCount was defined locally in the product module, creating a
parallel authority for the Count-axis concept. Moved to std/measure.dag
alongside its siblings (CpuCoreCount, MergeQueueEntryCount, etc.) with
constructor and accessor functions. The product module now imports it
from std.measure.

The review's argument is correct: §3 requires a single authority for
Count-axis aliases, and an alias in a product module re-mints the
pattern that std.measure already owns.

Review 60291: accepted. Fixed in commit 70e4162 (held locally until main's break clears).

PowerCordCount moved from the product module to dag/std/measure.dag alongside its Count-axis siblings (CpuCoreCount, MergeQueueEntryCount, etc.), with power_cord_count() and power_cord_count_value() accessors. The product module now imports it from std.measure instead of defining locally. The review's §3 logic is correct — once the Count axis has a single authority in std, a local alias is the fork the rule exists to prevent.

mtbf_hours already carries the tracked feature:extdeps-hour-scale gate with dissolves_on: — confirmed as non-blocking.

main is red on `required-ci: regen FAIL generated surface drift: compiler_tests.rs,
std_measure.rs`, and has been since #10273 merged at 19:59:28. This takes the candidate bytes for
exactly the two files adjudication named. No authored content.

WHY THE DRIFT EXISTS, because it is not a mystery and the shape matters. #10273's branch DID run
regen -- twice, in commits of its own. Two further commits then landed on top, the last being
"Move PowerCordCount to std/measure.dag (review 60291)", which edited the authority and never
re-ran the regen those earlier commits had already satisfied. So the mirror is behind the authority
by exactly one type: `dag/std/measure.dag` declares `PowerCordCount` three times and the emitted
`src/v1/stage0/src/std_measure.rs` carried it zero times.

std_measure.rs (+13): the `PowerCordCount` alias beside its Count-axis siblings, plus the
`power_cord_count` constructor and `power_cord_count_value` accessor. Mechanically what the .dag
declares.

compiler_tests.rs (+47): RESTORES the `nested_refinement_cast` closure-discrimination test that
#10266 added and #10273 DELETED. #10273's commit message reads "the regen phase found
compiler_tests.rs had a committed test that the emitter no longer produces" -- but the emitter does
produce it, which is why regenerating from this tree puts it back byte-for-byte. That deletion was
a stale-candidate artifact, and it removed enrolled evidence rather than dead bytes, which is the
more serious half of this repair: a drifted mirror reds the build loudly, but a silently deleted
test is DESIGN section 4b(4) dissolution applied to the evidence instead of the production handling.

The mirror is not self-healing. heal-generated-artifacts ran on main and did not clear this; it
stages 2 of ~136 stage0 files and neither of these is among them, so a drifted seed always requires
an author commit.

required-regen named three drifted stage0 mirrors; the previous cycles installed

* The where-refinement predicate vocabulary, joined to the compiler that decides it

A where-refinement predicate is a bare identifier with no declaration
binding anywhere in the pipeline: 02_parse accepts any identifier in its
unparenthesised arm, and 04_infer decides what it MEANS by matching that
string against three hand-written name-keyed tables. So the tables are a
second authority for a predicate's meaning, forked from the declaration
that already states it wherever one exists.

Census over all 4663 .dag files: 271 declaration sites, 15 distinct
predicate spellings. Seven are grounded by a declared total Bool function
and eight are not, and the compiler's treatment does not track that split
in either direction. Three grounded, decidable String -> Bool predicates
are in no table at all -- two of them declared in the same file as an
enrolled pair -- so a plainly invalid literal at those refined positions
compiles with zero refusals, while the enrolled siblings wall.

This lands the join that did not exist: one row per spelling carrying the
compiler's enforcement class and whether a declaration grounds it, and a
witness that executes every row against the real v1 compile path. The
join runs in both directions by spelling, so a spelling added to one side
alone reds rather than being skipped, and the three unenrolled rows are
held as a monotone debt contract at spelling grain -- enrolling one
without deleting its row reds, adding a fourth reds.

Honest at rung 2, mechanically preventable, and the row says so: the
invalid state stays writable and safety depends on the witness staying
enrolled. The observable is the two-way partition {refuses a violating
literal} vs {never refuses}, because the census surface projects a
diagnostic's class and subject name but not its reason; the four-way
class split is author-vouched and the file states which half executes.

* Record the ResolvedFormal reuse refusal in the trigger row, not the thread

Asked the lane carrying gunbc#10146 whether its ResolvedFormal /
DeclarationBoundFormals coproduct generalises from call formals to
where-predicates. It does not, and the reuse was refused: its fields are
parameter_identity, declared_type, declaration_bound_conformance and
substitution_basis, and its consumers depend on formal-to-argument
correspondence, so a predicate inhabiting it would give those four fields
a second meaning under one name -- the DESIGN section 3 fork this row
exists to close, re-created while closing it.

What generalises is the pattern, not the carrier, so the predicate move
owes its own substrate carrier keyed by DeclarationRef rather than
spelling, as a follow-on after #10146 rather than folded into it.

This lands in the dissolution-trigger row because a refusal that lives
only in a chat message is not an authority: the next person to propose
the reuse would not find it, and would re-derive the fork the refusal
prevented.

* Hoist every annotation to module-item grain, and import the name I used

The floor refused at parse with 45 errors, all in these two files, all one
class: DESIGN section 4c admits only standalone leading // blocks attached
to module-scope declarations. I had field notes inside a type body, a note
inside a data list literal, and a trailing ceiling block with no
declaration after it. Each is moved above the declaration it describes; no
prose is lost and none of it changes meaning.

Also adds NonEmptyStr to the std.types import. The roster used it in
where_predicate_decl without importing it, which produced two
unlisted-import-use advisories -- rows in a class this lane does not own
and therefore has no business creating.

WHY THE LOCAL RUN MISSED IT, since the instrument gap is the reusable part:
an entry-closure run (--entry <witness> --claim-run) resolves and executes
the witness without applying the annotation-grain rule, so all seven
assertions passed green against the real corpus while the file was
inadmissible to the compile-clean gate. Those are two different claims. A
whole-tree `gunbc compile --source-root dag --source-root src/v2 --target
dag` DOES apply it, reports zero annotation errors here, and is what
verified this fix before it was pushed.

* Record when this witness actually runs, because it is not every run

The floor passed and required_floor_disposition.tsv shows all seven
identities as planned_as_changed_witness / passed -- so they executed, and
were not selected out. But they are the ONLY seven rows of that
disposition in a 15984-row floor, and the arm name says why: they ran
because these files CHANGED. The floor's other arms are 3595 planned
(inside the gate closure) and 11824 declined_outside_gate_closure.

The sibling settles which arm this lands in once it stops changing.
test.claim.compile_diagnostic_census_witness -- same directory, same host
builtin, the module this witness was modelled on -- is
declined_outside_gate_closure on that same run. So this is a
change-triggered control, not a continuously-executing one, and the
roster's claim that safety depends on the witness "executing and staying
enrolled" was reading as more than the evidence supports.

The consequence is narrower and worse than the general point, so both
files now state it: an edit to this roster or the witness re-runs the
join, but AN EDIT TO THE COMPILER'S CLASSIFIER TABLES DOES NOT. The join
reaches the compiler through the compile_dag_diagnostic_census host
builtin rather than an import edge, and src/v1 is not a source root under
the required floor, so v1.compiler.infer cannot appear in this module's
closure at all. Enrolling a sixteenth predicate without touching either
file would not red. The wall catches ROSTER drift, not COMPILER drift, and
only the latter is the side that moves when someone enrols a predicate.

Next-rung trigger is named as the capability: this module inside the
required gate closure, reached from the gate seeds rather than by having
been edited, sufficient for the join to execute on runs that touch neither
file.

* Name the collision assertion, and bound the population it ranges over

The brief required the witness cover the collision case -- a spelling
standing for more than one declared meaning must go loud -- and
w_roster_spellings_are_pairwise_distinct already did, since two rows
claiming one spelling is how a second meaning enters the roster. But the
file described it as a byproduct of the bidirectional join rather than as
the collision wall, so a reader could not tell that was its purpose and
nothing said what population it ranges over. An assertion that satisfies a
requirement without being legible as satisfying it is how a check later
gets cited for coverage it does not have.

It now says both halves. It ranges over the ROSTER and catches a spelling
given two groundings there. It does NOT range over the corpus: two
declarations claiming one predicate name where neither reaches this file
are invisible to it, for the same reason the membership half is
author-vouched -- no substrate reader projects where-clause predicates, so
there is nothing to join the corpus against.

The corpus is collision-free as measured at authoring time -- 15 spellings
each denoting one thing, and 230 brand("...") literals all distinct -- and
it is held that way by authoring diligence, rung 1, not by this witness.
That is stated in the file rather than left as an impression, because the
earlier draft of this lane's report called name-keyed predicate identity
"silent wrongness" when nothing in the tree currently triggers it.

* Brand identity is the declaration, not the literal (collision refuses)

A `where brand("...")` refinement is a NOMINAL claim: two independently
declared types are different types. v1.compiler.infer decided brand identity
by comparing the LITERAL STRING -- where_refinement_predicates_equivalent
dispatched Brand to where_predicate_literal_string_args_match -- so two
declarations sharing a spelling were ONE type, and a cast between them was not
merely unenforced, it was not a cast at all. DESIGN section 3's meaning fork
with the halves swapped: not one concept wearing two names, but one name
silently merging two concepts.

THE COLLISION WAS AUTHORED HERE AND ACCEPTED SILENTLY. gunbc.fleet
fleet_site_locale carries an annotation recording that its first revision
minted a second HostIdentity beside product.placement_supply's, calling it the
single-authority violation in its canonical form, and stating that it DID NOT
SURFACE AS A DUPLICATE-DECLARATION DIAGNOSTIC. A person caught it and wrote the
incident into prose because there was no mechanism to write it into.

Brand equivalence is now decided where BOTH resolved types are in hand, in
where_refinement_mismatch_diags, and refuses only when both sides carry a Brand
predicate AND their declaring ident spans provably differ. The refusal reuses
type_mismatch_error -- the same TypeMismatch the refinement path already emits,
so no second authority for one meaning.

THE KEY IS THE DECLARING IDENT SPAN AND DELIBERATELY NOT Node.occurrence_identity.
Occurrence identity makes the collision refuse and ALSO makes a type stop being
itself when reached from a second use site, silent in the opposite direction --
and it is the live subject of the namespace/type-occurrence cutover.

MEASURED, four arms, `gunbc compile --source-root dag --source-root src/v2
--entry <fixture> --target dag`, before and after:

  collision  two decls one literal, cast between   0 rows        -> RC=1 blocking
  mismatch   two decls two literals, same cast     1 advisory    -> RC=1 blocking
  construct  String asserted into a brand          1 advisory    -> unchanged
  dual       one decl reached from two use sites   clean         -> unchanged

construct and mismatch emitted the IDENTICAL deferred advisory beforehand, so
the diagnostic separated a violation from a correct construction not at all.
That is why "make the Brand advisory blocking" is not a candidate wall: it would
refuse every construction site in the corpus and distinguish none of them.
construct keeping its advisory verbatim is the evidence the wall did not swallow
the base-to-brand assertion; dual staying clean is the evidence the key is
stable across occurrences.

NOTHING IN THE CORPUS REFUSES. Annotation-erased census over dag and src: 236
brand declarations, 236 distinct literals, zero duplicates. Authority move, not
a replacement migration. The erasure is load-bearing -- a raw grep reports four
duplicates and all four second sites are `//` prose, which section 4c makes a
structural correction since semantic passes see the annotation-erased projection.

Admitted against the v1 freeze by PURPOSE on gunbc.v1_maintenance_standing
v1_seed_standing: 236 declarations carry an identity v2 must eventually ingest
and would otherwise inherit wrong. No hand-authored Rust is added -- the stage0
mirror is regenerated -- so seed_growth_admission has nothing to admit.

RUNG HONESTY. The collision class reaches structural refusal on the
source-to-interpretation path; mismatch refusing is a separate and weaker claim,
since Brand remains a deferred predicate, now deferred over a real identity. Per
4b(4) the two expecting-red arms do not retire on the climb -- they become
permanent regression controls, and the two accepting arms are what prove the
wall did not swallow legitimate construction.

* The witness could not compile: compile_dag_diagnostic_census is a host builtin

The import list named compile_dag_diagnostic_census as an export of
gunbc.compile_diagnostic_census. It is a HOST BUILTIN and that module does not
export it -- the sibling witness using the same builtin imports only the types
and the row helpers. So the file failed to compile and none of its five
assertions ran.

WHY EVERY SIGNAL I HAD WAS COMPATIBLE WITH THIS. I verified the wall by running
the four arms as DIRECT FIXTURES, which proves the COMPILER refuses correctly
and is silent on whether the witness enrolling that proof works. Those are two
claims and I collapsed them. A witness that fails to compile emits no advisories
(a file that does not compile contributes none), fails no assertions (none run),
and is ABSENT from the floor disposition rather than failing in it -- so fmt,
the push, the arms and a source-reading APPROVE were all green over a dead file.

It surfaced from a whole-tree census run aimed at an unrelated question, as
blocking error number one. That is the recognition rule: if the only thing that
would have caught it is a run aimed at something else, the class has no
dedicated detector. The one instrument that sees it is a whole-tree compile
INCLUDING the test roots.

All five assertions now execute and pass under
`gunbc run --entry <witness> --claim-run --function <fn>`:

  b_all_four_arms_are_enrolled                PASS
  b_arm_names_are_pairwise_distinct           PASS
  b_every_arm_behaves_as_declared             PASS
  b_collision_and_dual_are_distinguished      PASS
  b_mismatch_and_construct_are_distinguished  PASS

Corrects the census receipt sent alongside this work: 37 blocking are
pre-existing in the corpus and 1 was mine. Advisory figures are unaffected --
17368 total, 8345 unlisted-* at 48.0% -- because a file that fails to compile
contributes no advisories either.

* File the class this change found: a witness that fails to compile is ABSENT, not red

INVALID STATE: a claim file is committed, reviewed and merged while it cannot
compile, so none of its assertions execute and the guarantee it was written to
carry does not exist.

WHY IT IS A CLASS AND NOT A SLIP: every ordinary signal is compatible with the
dead file and none of them is malfunctioning. It emits no advisories, because a
file that does not compile contributes none. It fails no assertions, because
none run. It is ABSENT from the floor disposition rather than failing in it, so
a disposition read shows nothing to investigate. fmt is green, the push is
green, and a reviewer can APPROVE on a correct reading of the source, because
READING DOES NOT COMPILE.

THE CORE IS A TWO-CLAIM COLLAPSE. "The compiler behaves correctly" and "the
witness that enrols that behaviour as executing evidence works" are different
claims; running the subject as a direct fixture establishes only the first. The
mechanism of the misread is that holding the stronger claim's output makes the
weaker one feel answered -- the author has passing fixtures in hand, which is
exactly why the file meant to carry them never gets checked.

RECOGNITION RULE: ask what would have caught it, and if the only answer is a run
aimed at a DIFFERENT question, the class has no dedicated detector. This
specimen surfaced from a whole-tree advisory census re-derivation chasing an
unrelated hypothesis about a denominator, as blocking error number one, after
the arms were green and an APPROVE was already recorded.

Rung found at 1. Ceiling 3: the population is decidable and closed -- every file
under the claim roots -- so a required step that compiles them and refuses a
non-compiling claim file makes the state unwritable in an Accepted tree. The
trigger names that capability and not an artifact, because an execution roster
keyed to compiling files cannot see a file that fell out of it, which is the
same shape as a check whose population IS its own roster.

* chore: regenerate drifted generated artifacts (ci auto-heal)

* Read the immediate operand, not the cast-peeled value, so brand -> base -> brand stays legal

The brand nominal-identity wall refused `x as String as X`, because it asked
`where_refinement_value_under_cast` for the actual type and that helper peels
through EVERY cast in a chain -- correct for a literal-argument predicate, wrong
for a nominal brand, where the immediate operand is the whole question. Four
corpus-authored sites in src/v2/extdeps/formats/spice_passive_projection.dag
spell exactly that, and the required floor refused them.

The check now reads `resolved_type(n: value_expr)` -- the unpeeled operand --
and reports it in the diagnostic's `got:` field.

The root cause was an INCOMPLETE PARTITION of the accepting cases: `construct`
covered base -> brand and `dual` covered one declaration referenced twice, and
neither covered brand -> base -> brand. So a fifth arm `strip` and the
regression control b_strip_is_accepted_where_bare_mismatch_refuses are enrolled
here; per DESIGN.md 4b(4) that control does not retire when it greens.

Evidence, all on the rebuilt seed:
  collision RC=1 blocking  mismatch RC=1 blocking
  construct RC=0           dual RC=0            strip RC=0
  positive control: the real spice_passive_projection.dag compiles, RC=0,
  zero blocking, all four sites back to advisory -- the check that separates
  "the wall works" from "the wall is gone".

* chore: regenerate drifted generated artifacts (ci auto-heal)

* Take main's design-failure-modes projection verbatim: the provisional-bytes route deleted two rows

The generated-artifact driver REFUSES rather than answering -- it leaves the ours
side in the worktree with no conflict markers and marks the path unmerged. So the
worktree read shows a clean, well-formed, already-resolved-looking file, and step 1
of the printed route (`git add` the driver-left bytes) commits that side over
main's, deleting rows it never mentions.

Measured on this head before the fix: main 98 projection rows, this branch 97,
authority 99. The two that went dark were denominator_moved_between_measurement_and_comparison
and absent_reads_identically_to_never_looked -- both main's, neither named in any
diff I read, and invisible to every gate: this would have merged clean.

Taking main's projection verbatim leaves the tree authority-ahead by this branch's
own single row and DELETING NOTHING, which is the benign shape heal is built to
close. It hand-authors nothing and cannot get the append order wrong.

A count does not catch this. The check is the set difference, which names WHICH
rows went dark:
  comm -23 <(main rows) <(head rows)   must be empty

* chore: regenerate drifted generated artifacts (ci auto-heal)

* Close the fail-open in the brand wall: an undeterminable declaration key is no longer representable

The wall admitted a cast it could not adjudicate. `where_refinement_brand_declaration_key`
returned "" for a type with no declaring span and the consumer guarded on `key != ""`, so
"I cannot tell which declarations these are" was spelled as a value and read as permission.

THIS WAS LIVE, NOT THEORETICAL. `fn f(a: String where brand("x"))` is an inline brand-carrying
type with no declaration site; it parses and compiles. Through it, brand `q_inline` flowed into
brand `q_b` -- the exact violation the `mismatch` arm exists to refuse -- and the file COMPILED
CLEAN. A hole in a wall emits no diagnostic, so no red existed for review to find: three reviews
read this diff and approved it, including one that described the partition as correct.

THE ROOT WAS THE RETURN TYPE, NOT THE ARM. `Bool` carried a three-valued question -- distinct
declarations, same declaration, cannot determine -- so the third collapsed onto `false` with the
second, and `false` admits. Fixing only the sentinel would have left the next consumer free to
re-derive the same collapse.

  - the key producer returns `String?`; an undeterminable key is NOT REPRESENTABLE
  - the predicate returns `BrandNominalVerdict`, four named variants, so no consumer can
    inherit an answer from a magic value
  - the undeterminable arm REFUSES via `inference_error` -- typed, located, and a DISTINCT
    diagnostic from TypeMismatch so the two populations never merge

Per DESIGN 4b this is construction over validation: the invalid state loses its constructor
rather than gaining a check.

Evidence, all on the rebuilt seed (six arms, three refusing and three accepting):
  collision RC=1   mismatch RC=1   undeclared_site RC=1 (was RC=0 -- the hole)
  construct RC=0   dual RC=0       strip RC=0
  positive control: real spice_passive_projection.dag RC=0, zero blocking, zero mismatches
  seven witness assertions PASS, including b_undeclared_site_refuses_like_a_declared_mismatch

The specimen is appended to the existing `state_space_conflation` row rather than minting a new
class -- its recognition rule already covers a value meaning more than one thing. Two things this
specimen adds: the collapse direction here was toward the ADMITTING value, so the type's
inadequacy IS the safety hole rather than a symptom of one; and it was found by EXECUTING a
fixture, where that row's earlier receipts were all found by reading the producer.

Two derived artifacts had to be re-derived rather than hand-resolved:

* Scope the brand witness to the diagnostic class it claims to prove

codex review 60451: the arms counted every blocking diagnostic in the compile
census, but gunbc.compile_diagnostic_census states the row set is the whole
compile's and that only a count scoped to a class -- or a differential -- is
exact. A bare `blocking >= 1` would stay green if the nominal check regressed
while an unrelated refusal appeared in its place.

Each arm now declares the class it expects (TypeMismatch for the cast arms,
InternalError for the undeterminable-site arm) and the refusing assertion is
`targeted >= 1 && targeted == total_blocking`, so an unrelated blocking
diagnostic reds the arm rather than satisfying it. The accepting arms keep a
TOTAL count, because "accepted" must mean no blocking diagnostic of any class.

Falsifier: perturbing expect_class to UnresolvedType turns
b_every_arm_behaves_as_declared, b_collision_and_dual_are_distinguished and
b_mismatch_and_construct_are_distinguished RED (RC=1); all seven are green with
the correct classes.

* The where-refinement predicate vocabulary, joined to the compiler that decides it

A where-refinement predicate is a bare identifier with no declaration
binding anywhere in the pipeline: 02_parse accepts any identifier in its
unparenthesised arm, and 04_infer decides what it MEANS by matching that
string against three hand-written name-keyed tables. So the tables are a
second authority for a predicate's meaning, forked from the declaration
that already states it wherever one exists.

Census over all 4663 .dag files: 271 declaration sites, 15 distinct
predicate spellings. Seven are grounded by a declared total Bool function
and eight are not, and the compiler's treatment does not track that split
in either direction. Three grounded, decidable String -> Bool predicates
are in no table at all -- two of them declared in the same file as an
enrolled pair -- so a plainly invalid literal at those refined positions
compiles with zero refusals, while the enrolled siblings wall.

This lands the join that did not exist: one row per spelling carrying the
compiler's enforcement class and whether a declaration grounds it, and a
witness that executes every row against the real v1 compile path. The
join runs in both directions by spelling, so a spelling added to one side
alone reds rather than being skipped, and the three unenrolled rows are
held as a monotone debt contract at spelling grain -- enrolling one
without deleting its row reds, adding a fourth reds.

Honest at rung 2, mechanically preventable, and the row says so: the
invalid state stays writable and safety depends on the witness staying
enrolled. The observable is the two-way partition {refuses a violating
literal} vs {never refuses}, because the census surface projects a
diagnostic's class and subject name but not its reason; the four-way
class split is author-vouched and the file states which half executes.

* Record the ResolvedFormal reuse refusal in the trigger row, not the thread

Asked the lane carrying gunbc#10146 whether its ResolvedFormal /
DeclarationBoundFormals coproduct generalises from call formals to
where-predicates. It does not, and the reuse was refused: its fields are
parameter_identity, declared_type, declaration_bound_conformance and
substitution_basis, and its consumers depend on formal-to-argument
correspondence, so a predicate inhabiting it would give those four fields
a second meaning under one name -- the DESIGN section 3 fork this row
exists to close, re-created while closing it.

What generalises is the pattern, not the carrier, so the predicate move
owes its own substrate carrier keyed by DeclarationRef rather than
spelling, as a follow-on after #10146 rather than folded into it.

This lands in the dissolution-trigger row because a refusal that lives
only in a chat message is not an authority: the next person to propose
the reuse would not find it, and would re-derive the fork the refusal
prevented.

* Hoist every annotation to module-item grain, and import the name I used

The floor refused at parse with 45 errors, all in these two files, all one
class: DESIGN section 4c admits only standalone leading // blocks attached
to module-scope declarations. I had field notes inside a type body, a note
inside a data list literal, and a trailing ceiling block with no
declaration after it. Each is moved above the declaration it describes; no
prose is lost and none of it changes meaning.

Also adds NonEmptyStr to the std.types import. The roster used it in
where_predicate_decl without importing it, which produced two
unlisted-import-use advisories -- rows in a class this lane does not own
and therefore has no business creating.

WHY THE LOCAL RUN MISSED IT, since the instrument gap is the reusable part:
an entry-closure run (--entry <witness> --claim-run) resolves and executes
the witness without applying the annotation-grain rule, so all seven
assertions passed green against the real corpus while the file was
inadmissible to the compile-clean gate. Those are two different claims. A
whole-tree `gunbc compile --source-root dag --source-root src/v2 --target
dag` DOES apply it, reports zero annotation errors here, and is what
verified this fix before it was pushed.

* Record when this witness actually runs, because it is not every run

The floor passed and required_floor_disposition.tsv shows all seven
identities as planned_as_changed_witness / passed -- so they executed, and
were not selected out. But they are the ONLY seven rows of that
disposition in a 15984-row floor, and the arm name says why: they ran
because these files CHANGED. The floor's other arms are 3595 planned
(inside the gate closure) and 11824 declined_outside_gate_closure.

The sibling settles which arm this lands in once it stops changing.
test.claim.compile_diagnostic_census_witness -- same directory, same host
builtin, the module this witness was modelled on -- is
declined_outside_gate_closure on that same run. So this is a
change-triggered control, not a continuously-executing one, and the
roster's claim that safety depends on the witness "executing and staying
enrolled" was reading as more than the evidence supports.

The consequence is narrower and worse than the general point, so both
files now state it: an edit to this roster or the witness re-runs the
join, but AN EDIT TO THE COMPILER'S CLASSIFIER TABLES DOES NOT. The join
reaches the compiler through the compile_dag_diagnostic_census host
builtin rather than an import edge, and src/v1 is not a source root under
the required floor, so v1.compiler.infer cannot appear in this module's
closure at all. Enrolling a sixteenth predicate without touching either
file would not red. The wall catches ROSTER drift, not COMPILER drift, and
only the latter is the side that moves when someone enrols a predicate.

Next-rung trigger is named as the capability: this module inside the
required gate closure, reached from the gate seeds rather than by having
been edited, sufficient for the join to execute on runs that touch neither
file.

* Name the collision assertion, and bound the population it ranges over

The brief required the witness cover the collision case -- a spelling
standing for more than one declared meaning must go loud -- and
w_roster_spellings_are_pairwise_distinct already did, since two rows
claiming one spelling is how a second meaning enters the roster. But the
file described it as a byproduct of the bidirectional join rather than as
the collision wall, so a reader could not tell that was its purpose and
nothing said what population it ranges over. An assertion that satisfies a
requirement without being legible as satisfying it is how a check later
gets cited for coverage it does not have.

It now says both halves. It ranges over the ROSTER and catches a spelling
given two groundings there. It does NOT range over the corpus: two
declarations claiming one predicate name where neither reaches this file
are invisible to it, for the same reason the membership half is
author-vouched -- no substrate reader projects where-clause predicates, so
there is nothing to join the corpus against.

The corpus is collision-free as measured at authoring time -- 15 spellings
each denoting one thing, and 230 brand("...") literals all distinct -- and
it is held that way by authoring diligence, rung 1, not by this witness.
That is stated in the file rather than left as an impression, because the
earlier draft of this lane's report called name-keyed predicate identity
"silent wrongness" when nothing in the tree currently triggers it.

* Brand identity is the declaration, not the literal (collision refuses)

A `where brand("...")` refinement is a NOMINAL claim: two independently
declared types are different types. v1.compiler.infer decided brand identity
by comparing the LITERAL STRING -- where_refinement_predicates_equivalent
dispatched Brand to where_predicate_literal_string_args_match -- so two
declarations sharing a spelling were ONE type, and a cast between them was not
merely unenforced, it was not a cast at all. DESIGN section 3's meaning fork
with the halves swapped: not one concept wearing two names, but one name
silently merging two concepts.

THE COLLISION WAS AUTHORED HERE AND ACCEPTED SILENTLY. gunbc.fleet
fleet_site_locale carries an annotation recording that its first revision
minted a second HostIdentity beside product.placement_supply's, calling it the
single-authority violation in its canonical form, and stating that it DID NOT
SURFACE AS A DUPLICATE-DECLARATION DIAGNOSTIC. A person caught it and wrote the
incident into prose because there was no mechanism to write it into.

Brand equivalence is now decided where BOTH resolved types are in hand, in
where_refinement_mismatch_diags, and refuses only when both sides carry a Brand
predicate AND their declaring ident spans provably differ. The refusal reuses
type_mismatch_error -- the same TypeMismatch the refinement path already emits,
so no second authority for one meaning.

THE KEY IS THE DECLARING IDENT SPAN AND DELIBERATELY NOT Node.occurrence_identity.
Occurrence identity makes the collision refuse and ALSO makes a type stop being
itself when reached from a second use site, silent in the opposite direction --
and it is the live subject of the namespace/type-occurrence cutover.

MEASURED, four arms, `gunbc compile --source-root dag --source-root src/v2
--entry <fixture> --target dag`, before and after:

  collision  two decls one literal, cast between   0 rows        -> RC=1 blocking
  mismatch   two decls two literals, same cast     1 advisory    -> RC=1 blocking
  construct  String asserted into a brand          1 advisory    -> unchanged
  dual       one decl reached from two use sites   clean         -> unchanged

construct and mismatch emitted the IDENTICAL deferred advisory beforehand, so
the diagnostic separated a violation from a correct construction not at all.
That is why "make the Brand advisory blocking" is not a candidate wall: it would
refuse every construction site in the corpus and distinguish none of them.
construct keeping its advisory verbatim is the evidence the wall did not swallow
the base-to-brand assertion; dual staying clean is the evidence the key is
stable across occurrences.

NOTHING IN THE CORPUS REFUSES. Annotation-erased census over dag and src: 236
brand declarations, 236 distinct literals, zero duplicates. Authority move, not
a replacement migration. The erasure is load-bearing -- a raw grep reports four
duplicates and all four second sites are `//` prose, which section 4c makes a
structural correction since semantic passes see the annotation-erased projection.

Admitted against the v1 freeze by PURPOSE on gunbc.v1_maintenance_standing
v1_seed_standing: 236 declarations carry an identity v2 must eventually ingest
and would otherwise inherit wrong. No hand-authored Rust is added -- the stage0
mirror is regenerated -- so seed_growth_admission has nothing to admit.

RUNG HONESTY. The collision class reaches structural refusal on the
source-to-interpretation path; mismatch refusing is a separate and weaker claim,
since Brand remains a deferred predicate, now deferred over a real identity. Per
4b(4) the two expecting-red arms do not retire on the climb -- they become
permanent regression controls, and the two accepting arms are what prove the
wall did not swallow legitimate construction.

* The witness could not compile: compile_dag_diagnostic_census is a host builtin

The import list named compile_dag_diagnostic_census as an export of
gunbc.compile_diagnostic_census. It is a HOST BUILTIN and that module does not
export it -- the sibling witness using the same builtin imports only the types
and the row helpers. So the file failed to compile and none of its five
assertions ran.

WHY EVERY SIGNAL I HAD WAS COMPATIBLE WITH THIS. I verified the wall by running
the four arms as DIRECT FIXTURES, which proves the COMPILER refuses correctly
and is silent on whether the witness enrolling that proof works. Those are two
claims and I collapsed them. A witness that fails to compile emits no advisories
(a file that does not compile contributes none), fails no assertions (none run),
and is ABSENT from the floor disposition rather than failing in it -- so fmt,
the push, the arms and a source-reading APPROVE were all green over a dead file.

It surfaced from a whole-tree census run aimed at an unrelated question, as
blocking error number one. That is the recognition rule: if the only thing that
would have caught it is a run aimed at something else, the class has no
dedicated detector. The one instrument that sees it is a whole-tree compile
INCLUDING the test roots.

All five assertions now execute and pass under
`gunbc run --entry <witness> --claim-run --function <fn>`:

  b_all_four_arms_are_enrolled                PASS
  b_arm_names_are_pairwise_distinct           PASS
  b_every_arm_behaves_as_declared             PASS
  b_collision_and_dual_are_distinguished      PASS
  b_mismatch_and_construct_are_distinguished  PASS

Corrects the census receipt sent alongside this work: 37 blocking are
pre-existing in the corpus and 1 was mine. Advisory figures are unaffected --
17368 total, 8345 unlisted-* at 48.0% -- because a file that fails to compile
contributes no advisories either.

* File the class this change found: a witness that fails to compile is ABSENT, not red

INVALID STATE: a claim file is committed, reviewed and merged while it cannot
compile, so none of its assertions execute and the guarantee it was written to
carry does not exist.

WHY IT IS A CLASS AND NOT A SLIP: every ordinary signal is compatible with the
dead file and none of them is malfunctioning. It emits no advisories, because a
file that does not compile contributes none. It fails no assertions, because
none run. It is ABSENT from the floor disposition rather than failing in it, so
a disposition read shows nothing to investigate. fmt is green, the push is
green, and a reviewer can APPROVE on a correct reading of the source, because
READING DOES NOT COMPILE.

THE CORE IS A TWO-CLAIM COLLAPSE. "The compiler behaves correctly" and "the
witness that enrols that behaviour as executing evidence works" are different
claims; running the subject as a direct fixture establishes only the first. The
mechanism of the misread is that holding the stronger claim's output makes the
weaker one feel answered -- the author has passing fixtures in hand, which is
exactly why the file meant to carry them never gets checked.

RECOGNITION RULE: ask what would have caught it, and if the only answer is a run
aimed at a DIFFERENT question, the class has no dedicated detector. This
specimen surfaced from a whole-tree advisory census re-derivation chasing an
unrelated hypothesis about a denominator, as blocking error number one, after
the arms were green and an APPROVE was already recorded.

Rung found at 1. Ceiling 3: the population is decidable and closed -- every file
under the claim roots -- so a required step that compiles them and refuses a
non-compiling claim file makes the state unwritable in an Accepted tree. The
trigger names that capability and not an artifact, because an execution roster
keyed to compiling files cannot see a file that fell out of it, which is the
same shape as a check whose population IS its own roster.

* chore: regenerate drifted generated artifacts (ci auto-heal)

* Read the immediate operand, not the cast-peeled value, so brand -> base -> brand stays legal

The brand nominal-identity wall refused `x as String as X`, because it asked
`where_refinement_value_under_cast` for the actual type and that helper peels
through EVERY cast in a chain -- correct for a literal-argument predicate, wrong
for a nominal brand, where the immediate operand is the whole question. Four
corpus-authored sites in src/v2/extdeps/formats/spice_passive_projection.dag
spell exactly that, and the required floor refused them.

The check now reads `resolved_type(n: value_expr)` -- the unpeeled operand --
and reports it in the diagnostic's `got:` field.

The root cause was an INCOMPLETE PARTITION of the accepting cases: `construct`
covered base -> brand and `dual` covered one declaration referenced twice, and
neither covered brand -> base -> brand. So a fifth arm `strip` and the
regression control b_strip_is_accepted_where_bare_mismatch_refuses are enrolled
here; per DESIGN.md 4b(4) that control does not retire when it greens.

Evidence, all on the rebuilt seed:
  collision RC=1 blocking  mismatch RC=1 blocking
  construct RC=0           dual RC=0            strip RC=0
  positive control: the real spice_passive_projection.dag compiles, RC=0,
  zero blocking, all four sites back to advisory -- the check that separates
  "the wall works" from "the wall is gone".

* chore: regenerate drifted generated artifacts (ci auto-heal)

* Take main's design-failure-modes projection verbatim: the provisional-bytes route deleted two rows

The generated-artifact driver REFUSES rather than answering -- it leaves the ours
side in the worktree with no conflict markers and marks the path unmerged. So the
worktree read shows a clean, well-formed, already-resolved-looking file, and step 1
of the printed route (`git add` the driver-left bytes) commits that side over
main's, deleting rows it never mentions.

Measured on this head before the fix: main 98 projection rows, this branch 97,
authority 99. The two that went dark were denominator_moved_between_measurement_and_comparison
and absent_reads_identically_to_never_looked -- both main's, neither named in any
diff I read, and invisible to every gate: this would have merged clean.

Taking main's projection verbatim leaves the tree authority-ahead by this branch's
own single row and DELETING NOTHING, which is the benign shape heal is built to
close. It hand-authors nothing and cannot get the append order wrong.

A count does not catch this. The check is the set difference, which names WHICH
rows went dark:
  comm -23 <(main rows) <(head rows)   must be empty

* chore: regenerate drifted generated artifacts (ci auto-heal)

* Close the fail-open in the brand wall: an undeterminable declaration key is no longer representable

The wall admitted a cast it could not adjudicate. `where_refinement_brand_declaration_key`
returned "" for a type with no declaring span and the consumer guarded on `key != ""`, so
"I cannot tell which declarations these are" was spelled as a value and read as permission.

THIS WAS LIVE, NOT THEORETICAL. `fn f(a: String where brand("x"))` is an inline brand-carrying
type with no declaration site; it parses and compiles. Through it, brand `q_inline` flowed into
brand `q_b` -- the exact violation the `mismatch` arm exists to refuse -- and the file COMPILED
CLEAN. A hole in a wall emits no diagnostic, so no red existed for review to find: three reviews
read this diff and approved it, including one that described the partition as correct.

THE ROOT WAS THE RETURN TYPE, NOT THE ARM. `Bool` carried a three-valued question -- distinct
declarations, same declaration, cannot determine -- so the third collapsed onto `false` with the
second, and `false` admits. Fixing only the sentinel would have left the next consumer free to
re-derive the same collapse.

  - the key producer returns `String?`; an undeterminable key is NOT REPRESENTABLE
  - the predicate returns `BrandNominalVerdict`, four named variants, so no consumer can
    inherit an answer from a magic value
  - the undeterminable arm REFUSES via `inference_error` -- typed, located, and a DISTINCT
    diagnostic from TypeMismatch so the two populations never merge

Per DESIGN 4b this is construction over validation: the invalid state loses its constructor
rather than gaining a check.

Evidence, all on the rebuilt seed (six arms, three refusing and three accepting):
  collision RC=1   mismatch RC=1   undeclared_site RC=1 (was RC=0 -- the hole)
  construct RC=0   dual RC=0       strip RC=0
  positive control: real spice_passive_projection.dag RC=0, zero blocking, zero mismatches
  seven witness assertions PASS, including b_undeclared_site_refuses_like_a_declared_mismatch

The specimen is appended to the existing `state_space_conflation` row rather than minting a new
class -- its recognition rule already covers a value meaning more than one thing. Two things this
specimen adds: the collapse direction here was toward the ADMITTING value, so the type's
inadequacy IS the safety hole rather than a symptom of one; and it was found by EXECUTING a
fixture, where that row's earlier receipts were all found by reading the producer.

* chore: regenerate drifted generated artifacts (ci auto-heal)

* Re-derive the projection and regenerate the stage0 mirror after merging main

The merge brought #10402's 04_infer changes alongside the brand-verdict work.
Two derived artifacts had to be re-derived rather than hand-resolved:

- docs/design-failure-modes.md re-derived from the merged authorities
  (generated_artifact_gate main_wet), with the base side taken verbatim first
  rather than the driver-left ours bytes.
- src/v1/stage0/src/v1_compiler_infer.rs regenerated via
  claim_executor --required-regen. Pass 1 reported drift
  (first_generation_equal=false); pass 2 after rebuild reports
  first_generation_equal=true over 156 adjudicated files. This incorporates the
  regeneration #10402 landed without.

roster.dag resolved by counted union and verified by identity join: no row dark
on either side, no duplicates, no inventions.

* Scope the brand witness to the diagnostic class it claims to prove

codex review 60451: the arms counted every blocking diagnostic in the compile
census, but gunbc.compile_diagnostic_census states the row set is the whole
compile's and that only a count scoped to a class -- or a differential -- is
exact. A bare `blocking >= 1` would stay green if the nominal check regressed
while an unrelated refusal appeared in its place.

Each arm now declares the class it expects (TypeMismatch for the cast arms,
InternalError for the undeterminable-site arm) and the refusing assertion is
`targeted >= 1 && targeted == total_blocking`, so an unrelated blocking
diagnostic reds the arm rather than satisfying it. The accepting arms keep a
TOTAL count, because "accepted" must mean no blocking diagnostic of any class.

Falsifier: perturbing expect_class to UnresolvedType turns
b_every_arm_behaves_as_declared, b_collision_and_dual_are_distinguished and
b_mismatch_and_construct_are_distinguished RED (RC=1); all seven are green with
the correct classes.

review 60514: the header said "WHY FOUR ARMS AND NOT ONE" while six arms are
enrolled, and "THE FOUR FIXTURES ARE INVALID PROGRAMS" described a set that now
includes three accepting arms, which are valid programs.

Both are §4c annotations making false structural claims in the file whose whole
purpose is a wall's honesty. Corrected to six, and the invalid-program claim
narrowed to the refusing arms with the accepting half named explicitly.

Prose only; no assertion, fixture or class filter changes.
