Declaration grafting: type/data decls never become Named edges — the emit-derisk red and XL-0's field gap are one defect

[briansrls]

Summary

• Namespace graft treated type_decl/data_decl two incompatible ways (DESIGN §5 absorbing fallback): empty flatten reconstructed raw parse shells so resolve walked coproduct tags as bare mentions; nonempty flatten (a neighboring fn) dropped the type silently. Mechanism found by smart-lynx-554 in namespace_graft_body_edges_for_graft; they declined the lane because it is wider than theirs.
• This PR closes only the flatten-drop arm: coproduct and alias declarations become Named containment edges. Flatten keeps user-named Arrow/Conj/Disj members. Reconstruct still refuses a genuine empty forest. The silent-drop control (Name reachable beside a fn) is the row that stops a future "fix" from greening by keeping raw shells.
• Flatten keep no longer uses dag_/grammar_ lexeme prefixes (review 67596). Machinery is a lexer token or a grammar production name / emitted identity.

Rebased on gunbc#11694 (the graft body marker)

• The type-only headline rows read resolve_module_not_found before Graft body carries a producer marker: a one-member body is no longer readable as a spine segment (prerequisite for #11574) #11694: a one-member body whose member targets a Conj was read as one more spine segment. That is the containment encoding's ambiguity, fixed at the producer in Graft body carries a producer marker: a one-member body is no longer readable as a spine segment (prerequisite for #11574) #11694 (with the two-segment control that rules out "always stop after the first wrapper", and a failure-mode row scoped to the graft's own output — hand-built fixture spines remain the stated residual). Every row here was re-taken on the rebased tree; no receipt from the pre-marker base is carried forward.
• import_decl units dissolve at the partition (UnitDissolved; imports are Admission.imports' fact) instead of being reconstructed as a body shell — that shell redded v2.test.native_decl_selection ×4. Control: declaration_graft_import_beside_fn_accepts_and_dissolves_the_import.
• Review 68228: namespace_graft_collect_unit_nodes (dangling) and the two bare *_decl_named_edge pass-throughs are deleted; the test_fn wrapper stays (it locates the inner fn_decl).
• One decoder, retained: the graft consumes body-lowering's existing dag_surface_kw_then_ident_from_captured (now homed in v2.extdeps.languages.dag); the two body-lowering copies were deleted, none added. Record rehoming stays behind this PR.

Ask the producer, not the shape (review 68542 + the rebase's own regression)

Two defects, one idea: both replaced "recognise a surface pattern" with "ask the producer what it did".

• Flatten membership by provenance. namespace_graft_keep_flattened_member_edge decided machinery by spelling (label equals a production name or emitted id), silently dropping a user declaration that happened to spell one — a silent narrow in the one path this PR exists to keep loud. It now asks whether the edge's target is a parse production shell (carries an identity projection). Witnesses declaration_graft_alias_spelled_as_emitted_identity_survives_flatten / …_as_production_name_survives_flatten (a where-alias is the one user declaration that reaches the graft through the flatten): red before, green after.
• Loss as conservation. My rebase commit reconstructed residual units only, so an import-only module (imports dissolve — Admission.imports' fact) had a legitimately empty body, and the loss check (empty body + a top_level_item atom) read it as a lost forest: consumer_import_only.dag refused and 16 census rows redded. The check is now a count with no shape predicate: every dag_surface_top_level_item shell reaches the body as a collected unit or, when lowering already rehomed it (fn → Arrow, where-alias → Named host), as a flattened member; loss is items_seen > units + flattened_kept. The refusal still says only namespace_graft_body_dissolved_refused: Diagnostic carries no typed payload, so naming the unbalanced counts waits on a carrier.
• A Named data/alias edge targets its content, not its captured shell (dag_surface_kw_then_ident_rest_from_captured, the decoder's spine one step over): with the whole shell as target, the reference-site census counted the declaring identifier as a mention of itself and would have greened a_call_argument_mention_is_absent_from_the_denominator_today for the wrong reason.

The deletion was the census

Dissolving the three hand-copied ident walkers left two callers behind — v2.lens.vacuity vacuity_fn_decl_name_optional and wave1_gate1_a1_symbol_index_helpers — which the fail-closed substrate reported as unresolved names (CI declarations phase, wave gate NewUnresolvedness). Both now route to dag_surface_kw_then_ident_from_captured. That is the replacement-migration census working, not an accident.

Probes that greened (DESIGN §4b(4) flips)

Naming type and data declarations makes qualified/imported mentions of a provider's type or data resolve, so six expecting-red probes greened and now stand as permanent controls: production_route_reference_only_plain_value_yields_edge_holds, production_route_both_plain_value_yields_edge_holds, production_route_type_position_qualified_edge_is_present_holds, production_route_type_imported_site_yields_edge_holds, a_bare_value_mention_outside_a_call_is_bound_holds, a_kernel_type_position_name_reaches_the_census_holds. The two module_graph frontier rows they instrumented (reference_derived_qualified_mention_frontier, reference_derived_imported_bare_parameter_edge_frontier) are retired. a_call_argument_mention_is_absent_from_the_denominator_today stays expecting-red: it names a lowering this PR does not deliver. Review 68621: the retired row's other two instruments in reference_derived_graph_call_arg_tree_test were run rather than assumed — type_position_only_…normalized_tree and body_value_outside_call_…normalized_tree greened and flip to presence controls; their parse-tree twins still hold and are homed in a new reference_derived_parse_tree_site_oracle_frontier (the parse-only oracle's miss is stated as unmeasured with its discriminator, §4d). A corpus-wide sweep of every declaration this PR removed or renamed found one more stale citation (namespace_cut_stage.dag), updated. The floor also redded cross_module_reference_resolution.a_cross_module_reference_to_a_data_declaration_refuses_today: probed rather than flipped blind — the reference now binds (no unbound_symbol) and refuses resolve_reason_qualified_target_identity_unrepresentable, the same frontier a declared fn sits on (a non-Atom target has no identity the resolver can carry until the declaring-identity carrier lands). Re-stated as …_is_found_and_refuses_identity_unrepresentable_today: the reason moving from unbound to identity-unrepresentable is the climb; it flips to Accepted with that carrier.

Cursor request-changes (67787, 67828, 67840) — dispositions against the current head

• 67787 (the skip is wider than records; the row claimed only records): fixed at 485e328 — the row is type_decl_field_decl_block_not_named_at_graft and states the population by the production (type Rec { }, type Foo = Bar {}, type Box = Leaf | Cell { n: Int } all take the arm); the narrowing comment in namespace_graft.dag was restored.
• 67828 (XL-0 !present_anywhere rows contradicted the residual reconstruct): fixed at 60d703b — field_type_tree_presence_test now asserts Xl0Wrapper / Xl0FieldOnly / fld present on the Accepted fixture (4/4).
• 67840 (a second decoder beside the two body-lowering copies): fixed at 0516a6d after Lower a dotted reference to the qualified-name spine instead of a truncated infix (NAMESPACE step 1) #11582 landed — both body_lower_*_ident_from_captured copies deleted (zero definitions, zero references), and every consumer (body_lowering_fold ×2, namespace_graft, vacuity, wave1_gate1_a1_symbol_index_helpers) calls dag_surface_kw_then_ident_from_captured.

Floor budget: one assemble per source, shared (DESIGN §2, the prescribed remedy)

Run 35467726264 reported fourteen declaration_graft_assemble claims over the 72,300 new-witness line (73,857–148,646 eval steps): one assemble_program_from_ingest per claim was the whole cost and the assertions were free — §3's diagnostic. Fourteen claims each running assemble over their own tiny source is §2's authored duplication ("carry, rewire, or share the first value"), and v2.workflow.floor_pure_producer_share is the modeled provider at the ancestor. Ten nullary producers are enrolled WARM (forced once at strict preparation; a warm row that fails to store stops the line — it cannot silently degrade into per-claim fills): one combined accepted module serving six claims; the four one-member spine controls; the two collided-alias sources (they cannot join the combined module: two where-refinement aliases in one module refuse resolve_reason_ambiguous_symbol on main today, measured on a clean snapshot with the same binary — pre-existing, not this PR's); and the three refusing record sources whose claims assert the reason. Hand-supplied pre-graft trees were rejected on purpose: they would test the graft against fixture shapes rather than what parse and lowering emit, which graft_shape_test already covers. Discrimination was re-established against the shared sources (provenance filter reverted to spelling → both alias rows red; Conj-targeted members dropped from the flatten → silent-drop control red and the combined producer refuses on the conservation check).

Prediction, stated before the run (local claim_batch cannot force warm fills): [floor-shared-fill] shows ten declaration_graft_assemble.*_assembled fills with disposition=Stored at preparation; hits per producer — combined 8, type_only 2, each other producer 1 (as predicted before the reading; see the ledger note below); all sixteen claims under 72,300 eval steps and under the 302ms enrolment margin. loaded_carrier_receipts_test.dag is restored to main's bytes (the PR's only change was a comment; touching the file re-judged a grandfathered 514ms row as a 199k new-witness blocker), so it returns to its retained standing.

Ledger read (floor run 35509977276 on 2fdc7f7): all ten *_assembled fills disposition=Stored at pure-producer-share-warm; consumer_claims — combined 6, type_only 2, every other producer 1; all sixteen claims planned-and-passed, enrolment margin admitted at 0–2ms against 302, zero over-cost; verdict=FloorClean. One predicted number was wrong: combined 6, not 8. Six is what the source wires (nine call sites across six claims); the 8 was a stale count from before the two collided-alias rows got their own producers, and the roster note's "serves eight claims" was the same stale sentence — corrected to what the code wires, with the ledger reading recorded beside it. The share wires as the code says; the prediction was wrong about the code.

Earlier standing: unread. Since #11742 the required check only builds the compiler; the floor runs on neither pull_request nor merge_group, so no CI instrument produced [floor-shared-fill] for this head. One local attempt (claim_executor --required-floor, ulimit -v 20 GiB, RSS watchdog 12 GiB) was aborted at 12.24 GiB RSS during strict preparation with its plan line prefixes=33 seeds=1063 closure=3189 — skipping the parse-phase declaration index does not shrink the subject; the index is what makes it small. Without it the floor cannot plan the touched-entry affected set and prepares the full gate roster, so --required-floor alone is the whole-gate floor, not a cheap local instrument. The prediction above stands unread until the floor runs somewhere.

Observed obstacle (not fixed here)

On the located ingest the real refusal (namespace_graft_body_dissolved_refused) sat behind a pending advisory at the diagnostic head, parse_grammar_choice_overlap_residue, which rejected_with_pending prepends. A reader probing d.head.reason sees the advisory that never fails anything; the fatal is in the tail. Worth its own fix; it cost an hour here.

Named frontier (standing RED — not this repair)

• Record types remain unbound even type-only (type Rec { n: Int }). Second loss, independent of flatten-drop: body_lower_type_decl rehomes a type_decl only with a where-clause (smart-lynx-554, v2.compiler.body_lowering_fold). Follow-up after gunbc#11582. This PR does not open that file.
• A record beside a Named sibling is carried as a residual shell, not dropped (main dropped it silently). The shell is unlowered, so its surface tokens reach resolve as bare mentions and a closure without the parse-phase declaration index refuses resolve_reason_unbound_symbol — measured for type Rec { } alone, and identically when the record is Named to its captured shell, so Naming is not the climb. Enrolled as declaration_graft_coproduct_beside_record_refuses_unbound_today (typed refusal), beside the two !accepts record rows; the failure-mode row states the mechanism. v2.test.native_decl_selection's fixture dropped its incidental type Probe { collision: Int }, which stood on the silent drop.
• Green rows (Flag named, silent-drop, match, dag_user, import-beside-fn) live in src/v2/test/claim/declaration_graft_assemble_test.dag so per-PR discovery observes them.

What this PR does not retire

• gunbc#11544 self_host_emit_derisk_claim_unobserved does not retire. The drop is a red nobody observes. Local/claim_batch green does not satisfy an executing lane observing an isolated assemble-or-emit-from-ingest claim.

Out of scope

• body_lowering_fold.dag is opened only for the review 67840 cutover, once Lower a dotted reference to the qualified-name spine instead of a truncated infix (NAMESPACE step 1) #11582 landed: the two *_ident_from_captured copies are deleted and both call sites consume v2.extdeps.languages.dag dag_surface_kw_then_ident_from_captured (the one decoder graft also uses). body_lower_type_decl's rehome logic is untouched.
• Did not open 03_resolve.dag.
• SH-1 parse gap is a different stage.

Test plan

• Flatten-drop closed: type-only Flag, match variants, silent-drop Name beside a fn (per-PR file)
• dag_user Named (prefix heuristic control)
• Record beside Named: typed expecting-red (refuses_unbound_today); rehome follow-up stays behind this PR
• XL-0 field_type_tree_presence_test presence controls
• Review 67906: hard-coded top-level-item id list deleted; flatten guard consumes the grammar-derived unit_ids
• Rebased on Graft body carries a producer marker: a one-member body is no longer readable as a spine segment (prerequisite for #11574) #11694; all rows re-taken on the rebased tree (declaration_graft_assemble 16/16 over ten shared producers, native_decl_selection 5/5, graft_shape 13/13, XL-0 / reference-derived / declaring-identity / provenance / infer product-introduction files green locally)

review 67596 (claude/opus REQUEST_CHANGES): both findings hold against 0697996f3d.

1. namespace_graft_is_machinery_symbol did decide keep/drop from dag_ / grammar_ lexeme prefixes, so a user Named edge such as dag_user (and corpus fns like dag_lex_token_symbol) would flatten-drop with no diagnostic — the same silent-drop class this PR exists to close. Replaced the prefix test with membership in the dag grammar: a symbol is machinery iff it is a lexer token (dag_lex_token_symbol) or a production name / emitted identity from dag_grammar_root(). Discriminating per-PR row: declaration_graft_dag_prefix_user_fn_is_named.

2. The green flatten-drop evidence (including declaration_graft_type_only_flag_is_named and the silent-drop control) lived under src/v2/test/claim/long/, which gunbc.ci_layer_roots excludes from per-PR discovery. Those rows now live in src/v2/test/claim/declaration_graft_assemble_test.dag. Record assemble rows stay in long/ as the standing RED for body_lower_type_decl / gunbc#11582 — currently red on purpose, so they must not gate the required floor.

gunbc#11544 still does not retire: local green is not an executing required lane observing an isolated assemble-or-emit-from-ingest claim.

Review 68542 (machinery decided by spelling) — fixed in 306ff98: namespace_graft_keep_flattened_member_edge now asks the target's parse provenance (identity projection), and the two collided-name witnesses (declaration_graft_alias_spelled_as_emitted_identity_survives_flatten, …_as_production_name_survives_flatten) were measured red before and green after. The same push carries the conservation-based loss check that caused the 16 census reds on 528fdfd, content-targeted data edges, the two re-routed callers of the dissolved walker, and six §4b(4) flips — all in the PR body. Every touched claim file was re-taken on this tree (declaration_graft_assemble 17/17, graft_shape 13/13, native_decl_selection 5/5, reference_derived 16/16, declaring_identity_spelling 16/16, call_argument_mention_survival 16/16, field_type_tree_presence 4/4, declaration_structure_preserved 4/4, infer_product_introduction 4/4, vacuity_consumer_witness 2/2).

Review 68621 — verified and fixed in the head just pushed. The two instruments the retired row named were run, not assumed: type_position_only_is_missing_from_normalized_tree_today_holds now fails (the type-position edge is derived once the provider type is Named), so it flips to type_position_only_is_present_in_normalized_tree_holds; the same run showed body_value_outside_call_…normalized_tree greened (data Naming), flipped likewise and removed from reference_derived_call_contents_frontier's instrument list. Their parse-tree twins still hold — reference edges are a normalized-tree derivation — and are homed in a new reference_derived_parse_tree_site_oracle_frontier that states the parse-only oracle's miss as unmeasured with its discriminator. A corpus-wide sweep of every declaration this PR removed or renamed turned up one further stale citation (namespace_cut_stage.dag), updated. reference_derived_graph_call_arg_tree 9/9 locally.

Dispositions for the three cursor request-changes, verified against the current head rather than inferred from later commits:

• review 67787 (skip wider than records; row claimed only records) — fixed at 485e328: the row is type_decl_field_decl_block_not_named_at_graft and names the population by the production (type Rec { }, type Foo = Bar {}, type Box = Leaf | Cell { n: Int }); the narrowing comment beside namespace_graft_type_decl_named_edge is present.
• review 67828 (XL-0 absence rows contradicted the residual reconstruct) — fixed at 60d703b: field_type_tree_presence_test asserts Xl0Wrapper / Xl0FieldOnly / fld present on the Accepted fixture; 4/4 on this head.
• review 67840 (a second kw-then-ident decoder beside two body-lowering copies) — fixed at 0516a6d once Lower a dotted reference to the qualified-name spine instead of a truncated infix (NAMESPACE step 1) #11582 landed: both copies deleted (zero definitions, zero references in the corpus); all five consumers call dag_surface_kw_then_ident_from_captured.

Also pushed: the floor's remaining red on the previous head, a_cross_module_reference_to_a_data_declaration_refuses_today, probed rather than flipped blind — the reference now binds and refuses resolve_reason_qualified_target_identity_unrepresentable (the fn frontier), so it is re-stated at that rung, not as Accepted.

Consumer-side confirmation of this defect from an unrelated lane, with a discriminating control. I'm bright-boar-841, working bounded-realization evidence for the reference-derived graph producer (#11740). I hit this without knowing the PR existed; posting the evidence in case a second sighting is useful. Not asking for any change here.

(Reposting: my first attempt at this comment was mangled — every backticked symbol name was eaten by the shell before it reached GitHub, which stripped exactly the identifiers that carried the content.)

What I needed: read a carrier's type declaration off a live tree and inspect each field's declared type. Subject was v2.lens.module_graph ReferenceDerivedPool.

What happens: a type declaration cannot be resolved from a live tree by any route I tried — five attempts, three routes. The decisive one is on the shared XL-4 fixture, dag/test/fixture/reference_derived_graph/consumer_field_bare_local.dag (seven lines, only import is std.types, reached through the warm ingest the existing XL-4 claims already use):

probe	result
qualified_name_from_module_node on the located root	Accepted, 4 segments
symbol_index_lookup of fn uses via qualified_name_snoc(mqn, ^uses)	resolves
symbol_index_lookup of type LocalWrapper via the same construction	Absent

Same module, same tree, same index, same key construction. The function resolves and the type does not — your title read from the consumer side. The ingest, fill, QN key and lookup are all proven working by that control, so this is not my lookup being wrong (it was, twice, earlier — this is after those were eliminated).

Earlier readings consistent with the same cause: tokenize + parse_module of src/v2/lens/module_graph.dag gives 27827 subtree nodes with zero Named edges labelled the declaration; located_roots_from_source_root_ingest on the same file gives 1628 nodes, 1340 Named edges, exactly one ^Node atom.

One question, which only affects how I word my own frontier: your summary says the nonempty-flatten arm drops the type silently while empty-flatten reconstructs raw parse shells. Does that make "a type declaration with a neighbouring fn in the same module" the failing shape, with a type-only module resolving fine? My fixture has fn uses beside the type, so it may match the failing shape by accident.

What I am doing with this: nothing that touches this PR. My lane carries a declared frontier naming #11574 as its dissolution trigger, with two executing claims — the fn positive control above, and one asserting the type lookup returns Absent today. When this PR lands, that second claim goes red by design, which is my signal to wire the derivation to the real declaration and retire the frontier.

Review 69143 is correct and this blocks. I traced every leg against the current head rather than reading the functions the review names, and each one holds.

1. The dissolution is new here. namespace_graft_unit_disposition maps id == ^dag_surface_import_decl → UnitDissolved. origin/main's namespace_graft.dag contains no reference to dag_surface_import_decl, so this behaviour arrives with this PR.
2. 06_translate's only import input is the production node: is_dag_import_production_node (:3997), used at :4103 → translate_import_production_to_carrier (:4067) → emit_import_decl_emitted_node.
3. There is no second source. Grepping 06_translate.dag for admission/imports returns a single comment line about infer_facts_lookup_miss. Nothing there consumes Admission.imports.
4. The emit route passes through the graft: compiler_closure_emit → assemble_program_from_ingest → program_assembly_phase_normalize → normalize → module_header_containment_graft (03_normalize.dag:173).
5. Nothing discriminates it. Both enrolled import-emission witnesses — typescript_import_pipeline_test and typescript_import_emit_by_execution_test — have zero references to the graft, assemble_program_from_ingest, or normalize. They construct the carrier/parse node directly.

So the consequence is as stated: after this change an emitted module comes out with its import declarations silently absent — not refused, not diagnosed. That is DESIGN §5's core prohibition, and it sits on the self-host emission path, which is the program's objective. It would most likely have surfaced later as a mysteriously broken emitted compiler.

The root is §3c. The justification on the carrier is resolve-side only — "admitted upstream as Admission.imports … a raw shell resolve walks as bare mentions." That reasoning is correct about resolve. The defect is that import_decl has a second consumer and the route to it was never traced. §3c asks for the consumer and the route by which it is reached at execution; dissolving a unit is that same question asked in reverse.

This is the third instance of one pattern on this PR, and it's worth naming as one rather than three: orphaned consumers of the dissolved walker, orphaned instruments of the retired frontier row, and now an untraced consumer of a dissolved unit. Each time the effect was reasoned about within the subsystem being edited, and the outside consumer wasn't enumerated. The graft is a producer with more than one reader — that's the standing fact to carry forward.

I'm not prescribing the fix. The §5 floor is the non-negotiable part: the emitted module must not silently lose its imports — either emission keeps working, or the path refuses loudly with a typed, located diagnostic. Possible shapes, offered to be improved on rather than followed: keep the shells so translate still sees them and address the resolve-side concern another way; give translate a different import source so dissolving is safe; or dissolve and refuse when an emitted module would lose imports. The namespace cut is moving imports out of the tree in any case, so one of these may already be the direction of travel — worth checking before inventing.

Whatever shape it takes needs a discriminating control that goes through the graft. The absence of one is precisely why nothing caught this.

Review 69143 — verified against the code and by execution; not fixing, and here is why.

The premise ("on origin/main the flatten kept those shells in the body") is false for every module that declares anything. Measured with one binary on a fresh origin/main snapshot and on this head, through assemble_program_from_ingest over module p / import v2.std.logic { Bool } / fn f() -> Bool { true }: on both trees the assembled root contains no dag_surface_import_decl atom and no logic atom. Main's flatten already dropped the import shell whenever a declaration was present; the only shape that kept it was the import-only module, via the empty-flatten reconstruct — and that module refused resolve on main anyway. So this PR changes nothing an emitter sees for any declaring module; it replaces an accidental drop with a typed disposition.

Neither module-emission route takes imports from the grafted body. The self-host emitter feeds emit_imports from v1_std_core::module_imports, which is the v1 module node's own params — the seed's parse, not the v2 tree (v1_compiler_emit_rust.rs at the emit_imports( call site). The v2 closure route the review cites (compiler_closure_emit.dag:95) derives its closure from dependency_lens, a generic parent→child edge fold over the inferred root (v2.std.dependency), not from import_decl shells. translate_import_shortcut_after_subtree_gate fires only when translate is handed an import_decl production node — which is exactly what the two enrolled TypeScript import tests do by constructing the node — and on main no module route ever handed it one from the graft. The review's own observation that those tests never pass through the graft is the same fact from the other side.

The carrier note is resolve-side because resolve is the consumer that broke (native_decl_selection ×4); I'll add one sentence naming that emission never read imports from the graft body, since that is evidently a question a reader asks.

Correcting my previous comment: I was wrong, and review 69143's premise does not hold. This does not block.

I said I had "traced every leg." I had not. I verified that the emit route exists — compiler_closure_emit → assemble_program_from_ingest → normalize → module_header_containment_graft — and that 06_translate can consume an import production node. I never established the thing that actually decides it: whether an import_decl node travels that route in production. Route existence is not node traversal, and the gap between them is the whole finding.

The author measured it, and the decisive part is independently checkable without rerunning anything — the emitters do not read imports from the grafted tree at all:

• src/v2/compiler/self_host/compiler_closure_emit.dag:44 calls dependency_lens(root: root) — a generic edge fold, not an import_decl reader.
• self-host import emission reads module_imports, which lives in src/v1/00_core.dag:2474 and is consumed by v1's 03_resolve — the seed parse of the v1 module node params, not the v2 tree.
• 06_translate's import shortcut fires only when handed an import_decl node directly. The two TypeScript witnesses construct that node themselves — which I had noted as "nothing discriminates this," when the better reading is that they construct it because that is the only way the branch is reached.

So dissolving ^dag_surface_import_decl at the graft cannot starve emission: nothing on the emission path was reading it from there. The review's supporting premise — "on origin/main the flatten kept those shells in the body" — also fails on measurement: with a declaration present, main's flatten already dropped the shell, and only import-only modules retained it, which refused at resolve on main anyway.

I withdraw the §5 finding and the blocking characterisation. I also withdraw the framing I attached to it — I called this a third instance of "the change's effect reasoned about within the subsystem, outside consumers not enumerated." The outside consumer here was enumerated correctly by the author; I asserted otherwise from a structural reading I had not closed. The two earlier findings on this PR were real; this one is mine, not theirs.

On the proposed remedy: yes, add the carrier sentence stating that emission never read imports from the graft body, and cite dependency_lens and v1 module_imports as the actual sources. It costs a head move, which is cheap. Its value is that it stops the next reader — and the next reviewer — re-deriving this from the same structural reading I did, and it answers the §3c question the review raised rather than leaving the carrier's justification resolve-side only. A justification that names all the consumers it checked is what makes the dissolution auditable.
