Subject: [PATCH] Delete 7 unreachable library components, and gate the thing a
 census cannot see
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Seven components with no importer, removed. The interesting part is not the
deletion, it is that an import census was NOT sufficient to authorise it, and
two other agents proved that rather than me.

WHAT AN IMPORT CENSUS MISSED. internal/check-gospel-set-charts.mjs iterated
['BoundedSet.vue', 'CenteredSetTarget.vue'] as literal STRINGS and read their
props off disk. No import, so no census and no build would have warned; deleting
them would have turned a gate red on main with nothing to explain it. gospel
found that in their own file after I asked, and retargeted the arm at the
components that actually render (GiBoundedSetMap / GiCenteredSetMap, 2d2e853a7).
Their retarget also fixed a quieter defect: the seed guarantee had been asserted
against two files NOTHING renders, so it would have kept passing while the
shipping component grew a seed prop.

I did not take either agent's word for it. Verified gospel's retarget on their
sha and ran their gate green before deleting; verified upg100's structural claim
that packet-render.js cannot mount a component at all — 0 resolveComponent, 0
defineAsyncComponent, 0 dynamic import(), with the same probe returning a hit
elsewhere in library so an empty result is a real absence.

DELETED: charts/LanguageTreeChart.vue, components/charts/VisionFunnel.vue,
components/charts/BoundedSet.vue, components/charts/CenteredSetTarget.vue,
components/legends/ListSelectorLegend.vue,
components/dashboards/DashboardBreadcrumb.vue, composables/useMapSelection.js.

NOT DELETED, and worth stating because the names collide: the lowercase
boundedSet.js / centeredSet.js HELPERS are load-bearing — packet-render.js and
GiBoundedSetMap import them directly, and check-gospel-set-charts still does too.
Also left alone: colors/resource.js (a colour STRATEGY resolved by MODE NAME
through _registry.js, 'resource' appearing in mapStore.js and GiResources.vue)
and layouts/app-wrapper-material/nav.js (115 mentions). Both look dead to an
import census and would break a working map.

check:no-dead-library scans for a filename as a STRING across internal/,
library/ and plugin-designs/, and:

  · DISTINGUISHES A READ FROM A COMMENT (gospel's ask). check-packet-variants.mjs
    discusses CenteredSetTarget.vue in prose while asserting against JSON. A
    comment hit is reported, never fatal — a gate that cannot tell the two apart
    cries wolf once and is then ignored. It currently reports 4 such mentions.
  · IS TWO-SIDED (upg100's ask). It also asserts a KNOWN-PRESENT dynamic
    reference is found — LegendDesktop lazy-loads LegendMobile through import().
    Mutation-tested: blinding the scanner makes it FAIL on that control instead
    of passing with "no references found", which is what a one-sided version
    would have done.
  · ignores a longer identifier that merely contains the name, so GiBoundedSet.vue
    is not read as a reference to BoundedSet.vue.

Both arms mutation-tested and every mutated file restored byte-identical.
Registered in all three places and verified by re-reading the parsed
package.json — the suite insert silently hit the scripts KEY instead of the suite
string on the first attempt, which verifying caught and trusting would not have.

+ * check-no-dead-library.mjs — a library module must be reachable, and the scanner must prove it works.
+ *
+ * ★ WHY A NAME-GREP IS NOT ENOUGH, and why this file exists in this shape. Seven library components
+ * were deleted as unreachable. Two of them were NOT reachable by import and still could not be
+ * deleted safely: internal/check-gospel-set-charts.mjs iterated ['BoundedSet.vue',
+ * 'CenteredSetTarget.vue'] AS STRINGS and read their props off disk. No import, no build error —
+ * deleting them would have turned a gate red on main with nothing to explain it. So this scans for a
+ * filename appearing as a STRING anywhere in internal/ and library/, not only in import statements.
+ *
+ * ★ IT DISTINGUISHES A READ FROM A MENTION (gospel's ask). check-packet-variants.mjs discusses
+ * CenteredSetTarget.vue in prose while asserting against a JSON file. A gate that cannot tell a read
+ * from a comment cries wolf once and is then ignored, so a comment-only hit is REPORTED, never fatal.
+ *
+ * ★ IT IS TWO-SIDED (upg100's ask, learned the same night). A gate that only asserts "no references
+ * found" passes identically when the scanner is broken and when the tree is clean. So it also
+ * asserts a KNOWN-PRESENT reference is found: LegendDesktop.vue lazy-loads LegendMobile.vue through
+ * a dynamic import(). If that positive control ever stops being found, the scanner is lying and the
+ * gate fails — green here means "the scanner works AND found nothing".

-/**
- * LanguageTreeChart.vue — every language family a roster belongs to, as a radial tree on a whiteboard.
- *
- * Promoted from gospel-internet's GiTree (Driver brief §B). It is deliberately THIN: the drawing is
- * library/charts/whiteboard/tiered-points.js, the surface is library/maps/whiteboard-map.js, the
- * hierarchy is library/charts/whiteboard/language-tree-model.js and the camera is
- * library/charts/whiteboard/frame-target.js — all four tested headlessly. What is left here is wiring,
- * because an SFC cannot be run by a gate and so should hold as little as possible.
- *
- * ★ PROPS IN, EVENTS OUT. GiTree had NO props and NO emits: it read a board composable and a module
- * singleton, which is what made it gospel's rather than anybody's. Everything it reached for is now a
- * prop, and `selected` is a v-model so the HOST decides what a click means.
- *
- * ★ THE CLICK TOGGLE IS THE HOST'S, DELIBERATELY. GiTree cleared the selection when you clicked the
- * selected node again — and that toggle lived inside the component's own click handler, not at the call
- * site. Moving it out MOVES behaviour rather than codifying it, which is worth saying plainly: a host
- * that wants the toggle must write it. In exchange the chart holds no selection state at all.
- *
- * ★ FRAME ON SELECT, NOT ON CHANGE. Clearing does NOT re-frame: the camera stays where the reader left
- * it, because yanking it back is a motion nobody asked for. "Frames when the selection changes" is the
- * obvious phrasing and it is wrong in exactly one case, which is the case that annoys people.
- *
- * ★ AND A SELECTION SET BEFORE THE MAP IS READY IS REPLAYED. GiTree survived this by ordering: its host
- * set the node through a composable that waited for data, so the value always arrived after the map. As
- * a PROP the ordering belongs to the host, and a prop whose effect depends on WHEN you set it is a trap
- * for every future consumer — a shared deep link would work or not depending on load timing, which is
- * unreportable. So ready replays whatever `selected` currently is.

- * ring -1 IS "no relation found" AND IS NOT RING 10. The outermost ring is a measurement; no
- * relation is the absence of one. Collapsing them prints a group as "furthest" when the truth is
- * "we could not place it" — 11 rows fleet-wide, and every one of them would be a false statement.
- *
- * THE ARROW AND THE RADIUS MUST NAME THE SAME NEIGHBOUR. Both come from `rings`, never from
- * links[u][0], which is the older E-scale ordering and can disagree — that draws a ring-3 group with
- * an arrow at its ring-8 neighbour and nothing on the page says so. inwardArrow returns null when no
- * neighbour is recorded, and a null arrow is simply not drawn: an arrow is a CLAIM about a
- * relationship, so a guessed one is a fabricated claim.
- *
- * EVERY RING IS LISTED, INCLUDING EMPTY ONES. Under a filter several of the nine legitimately go to
- * zero, and a decoder that omits its empty rows stops being a decoder. Presence by identity, never
- * by count — the same rule the zone legend follows.
- *
- * ★ AND NO SEED: position is hashed from the group's own id, so two printings of one packet are
- * identical and a reader comparing sheets sees real movement rather than reshuffling.
- *
- * ★ A NOTE FOR WHOEVER BUILDS `labels.rings` — DO NOT PASS groupings.label AS A NAME. Measured on
- * the published file: those labels run 7 to 206 characters, and the long ones are the zone's MEMBER
- * LIST, not its name. Tibet's reads "Tibet Autonomous Region + Sichuan Province + Xinjiang Uyghur
- * Autonomous Region + Gansu Province + ..." — only 2 of the 14 carry no "+" list at all (Gujarāt,
- * and "Scattered / Diaspora"). Used as a heading on a printed sheet that sets a 206-character title.
- * The field is a DEFINITION and is genuinely useful where there is room to say what a zone contains;
- * for a name, humanise the slug, which is uniform by construction and tops out around 34 characters.
- * gospel found this and carries the two separately; this component asserts nothing about the words,
- * so the whole hazard lives at the call site, which is exactly why it is written down here.
- *
- * ★ THE AGREED RING VOCABULARY, for a caller building `labels.rings`. Settled between gospel and
- * exp and derived from exp's ringFor() rather than hand-numbered, so the numbering cannot drift
- * from the code that produces it. The screen legend already renders these words, so a printed sheet
- * using them cannot disagree with the screen:
- *
- *   1 Same dialect, same people      6 Same language, different culture
- *   2 Same dialect, near culture     7 Same family, same people
- *   3 Same dialect, different culture 8 Same family, near culture
- *   4 Same language, same people     9 Same family, different culture
- *   5 Same language, near culture   10 Nearby only
- *
- * ⚠ ONE CELL IS PROVISIONAL: "people" vs the brief's "culture" in column 1 is open on the Driver's
- * row 89. If he keeps "culture", exactly THREE cells change — 1, 4 and 7 — and nothing else: not
- * the numbering, not the columns, not the colours. That is why this map is written here as
- * VOCABULARY and is NOT a default: a default would bake a provisional word into every consumer that
- * forgot to pass one, and the component would become the thing that decided a Driver question. The
- * same reason ShareCalendar refuses to name its own metric.

-/**
- * VisionFunnel — the inverted triangle: all peoples → unreached → frontier, and where a list sits.
- *
- * ★ STEPS AND OVERLAYS ARE DIFFERENT THINGS, and this is the whole design.
- * A funnel's rhetoric is containment: of all peoples these are unreached, of those these are
- * frontier. That reading is only honest while each step is a SUBSET of the one above. DOXA is not:
- * of its 2,107 groups 2,082 are unreached and 1,745 are frontier, so 362 — one group in six — are
- * not frontier at all. Drawn as a fourth nested band it would misstate 17.2% of the list with a
- * clean shape and no error of any kind.
- *
- * So steps stack, and overlays are drawn as BRACKETS BESIDE the steps they reach into, never inside
- * them. The component asks packetCharts.overlayPlacement() whether an overlay is a slice rather
- * than deciding for itself, and refuses to render one as a band when it is not.
- *
- * PRINT FIRST (upg100): no hover, no tooltip. Every number is inked, including each overlay's parts.
- *
- * RTL: the triangle is vertically directional — it narrows downward — so it is NOT mirrored; a
- * scaleX flip would reverse nothing meaningful and invert any text inside it. What does need to
- * mirror is the label and bracket side, which is why those use logical properties (inset-inline,
- * text-align: start) rather than left/right.

-/**
- * ListSelectorLegend.vue — the Driver's VERTICAL LEGEND, used to SELECT a list and filter by it.
- *
- * @description The shared vertical legend wired as a SELECTOR: it renders the region → zone tree of
- *   a people-group list and emits the selection, so any dashboard can filter its groups by it.
- *
- * ★ IT WRAPS <SemanticTreeLegend>, IT DOES NOT REPLACE IT. That component is already the Driver's
- * vertical legend and already drives my-upg-100-list's 26-zone tapestry, so every fix it receives —
- * theme-awareness, the progress bar, the mobile-sheet path, the scroll-to-selected watcher — keeps
- * applying here. A second widget would have to re-earn all of it.
- *
- * ★ IT EMITS A ZONE ID, NOT A SELECTOR OR RESOLVED GROUPS (gospel's contract). An id is
- * SERIALISABLE — it survives ?zone=, profile-config and a deep link, which is the chain this
- * dashboard already resolves its list from — and a predicate is none of those. It also keeps this
- * component promotable: the moment it emits a selector it has to know what it selects OVER, and the
- * consuming dashboard holds four different row shapes across its tabs.
- * And the join stays in ONE place. Resolving zones to groups means folding diacritics (the
- * membership keys are ASCII while the province data is not — a naive join silently lost 495 groups),
- * bridging provinces, and asserting a known total. That logic lives in the consumer; a second copy
- * here would drift, and the drift would surface as a wrong COUNT, which nobody notices.
-
- * ★ AND IT NEVER DROPS A ZONE THE TREE FORGOT. Four joinable zones are absent from zone-regions.json
- * today — guizhou, xinjiang (100 groups on its own), bihar, madhya-pradesh — so grouping by region
- * loses them with no error and no empty state, just a shorter tree. Pass `allZoneIds` and they
- * appear in an explicit bucket instead. The consumer said it plainly: better the legend look wrong
- * than look fine.
- *
- * A REGION ROW SELECTS THE UNION OF ITS ZONES (dx-shepherd, provisional and reversible): clicking a
- * parent means "everything under here", which is what a reader expects of a tree and what makes the
- * top row useful as "all of this list".
