* fix(il2cpp): accept arm64 module arrays loaded through adrp/add pairs
A Unity 2022.3 macOS Master (LTO) arm64 build keeps no static CodeRegistration, so the module-array fallback that only decoded x86-64 RIP-relative references reported code-registration-not-found.
The registration owner now also decodes aligned adrp + add pairs in executable ranges and keeps the same exact-module-set and single-reference rules.
A minimal Mach-O fixture failed on the previous reader (47 passed / 1 failed) and passes here with four fail-closed variants (48/48 binary tests).
* fix(il2cpp): name the matched instruction form in inferred module-array limits
The inferred-array limitation always described RIP-relative LEA/MOV, which is wrong for arm64 results.
The provider now names the adrp/add pair on arm64, and the tool contract and docs cover both forms and state that a located array alone does not finish linking a Master build.
The new arm64 provider case failed before the wording change (1 passed / 1 failed) and both cases pass now.
* fix(il2cpp): accept type tables loaded without a static MetadataRegistration
A Unity 2022.3.62f3 macOS Master build inlines MetadataRegistration as well as CodeRegistration, so linking stopped at metadata-registration-not-found after the module array was found. Registration now infers the only field linking reads, the Il2CppType table, from the one run of type-shaped pointers that covers every referenced type index and whose start is loaded by the existing RIP-relative or adrp/add forms; types_field is null and the Evidence is inferred. The new arm64 and x86-64 fixtures failed on the previous reader (52 passed / 2 failed). Four run-selection variants (interior reference, run extended before the loaded address, two loaded runs, run shorter than the referenced indices) keep metadata-registration-not-found; instruction decoding and record-shape checks are not covered by these fixtures.
* test(il2cpp): pin adrp page deltas, register pairing and type-record shape
Every adrp fixture targeted its own 4 KiB page, so dropping the page delta or its sign extension, the add register check, the type-kind bound or the type-definition bound left all binary tests passing. Fixtures now reach a later and an earlier page, pair an add with a different destination or source register, break the type run with an out-of-range kind or type-definition index, and bound type-table candidates when the metadata references few type indices. Each of those five source mutations now fails 1 to 3 of 85 binary and provider tests.
* refactor(il2cpp): share Il2CppType kind decoding and document type-table bounds
The type-table fallback decoded the Il2CppType kind and class/value-type kinds separately from the type namer; both now use the Types owner. Zero and unaligned words are rejected before mapping lookup (Master sample metadata-registration search 92 to 68 ms). Docs and the limitation state that types_count is an upper bound, that a run spanning mappings or a small referenced type range can fail, and credit Cpp2IL StrippedCodeRegSupport and the data-side MetadataRegistration searches of Il2CppDumper and Cpp2IL. Master sample output is unchanged (11,031 code addresses, 37,025 type rows).
* fix(il2cpp): refuse generic instances when the type table was inferred
An inferred type table has no static MetadataRegistration, so the
genericMethodTable it would anchor cannot be located. Report
generic-methods-unsupported instead of reading from a null field.
* fix(il2cpp): fail closed when an inferred type table is not unique
Adversarial review found that the type-table fallback could pick another
type-shaped pointer table when the real one was unloaded or excluded, could
replace a static MetadataRegistration whose counts matched, and accepted a
run cut short by a mapping end. Require exactly one long-enough run in the
image, ending inside its mapping and loaded by code; skip the fallback when a
record's two counts matched; accept only assigned Il2CppTypeEnum kinds; and
look records up through the indexed file mapping so many mappings cannot
multiply the scan. Docs and limitations now describe the run length as at
least every referenced type index rather than an upper bound.
* fix(il2cpp): keep the type-table fallback cheap and its refusals exact
Review follow-ups: check that an address can lie in a mapping before the
throwing indexed lookup, so words pointing into gaps or zero-fill no longer
build an exception each (64 MiB: 74 s to under 2 s); treat a run starting at
its mapping start like one reaching its end; stop at the second long-enough
run instead of a 64-candidate capacity error; ignore ADRP/ADD pairs on
register 31; and say whether a counted MetadataRegistration was unusable or
no code-loaded run was found. Docs no longer generalize from one build or
state tool history they do not source.
* fix(il2cpp): judge type-table slots by their loaded value
The run scan read stored words, so a dyld-bound slot's placeholder could
decide whether a run qualified. Confirm each slot through readSlot and give
a run bounded by a bound or unresolved slot an unknown extent, so the
placeholder no longer changes the choice.
* docs(il2cpp): keep the failure-reason table layout
Shorten the two changed meanings so the table keeps its column widths and the
diff shows only those rows.
* docs(il2cpp): keep the reason table at its formatted width
* fix(il2cpp): read type-table record fields through the loader too
The previous change confirmed table slots through readSlot but still read
each record's kind and definition index from stored bytes. Read them with
readUInt32 and readSlot, and treat a record field the loader binds or leaves
unresolved like an unresolved slot: the run it bounds has an unknown extent.
* perf(il2cpp): share image mappings across loader-aware reads

* feat(il2cpp): read generic containers on demand and render method spec names
Generic container indices and records are demand readers on the same metadata snapshot, so links that do not ask for generic instances allocate nothing. Type rendering keeps one graph walk with its workspace, depth and cycle guards; the C#-like names and the Il2CppDumper GetMethodSpecName names are two styles over it.
* feat(il2cpp): link generic method instances with admitted rows and kept issues
generic_instances links every genericMethodTable row through methodSpecs, genericInsts and genericMethodPointers, choosing the one CodeRegistration layout whose counts bound every row. The table is reserved against the report budget before any row is resolved; rows and issues are admitted before retention, and a contradicting row stays unknown with an address-backed issue instead of failing the link. Views page the rows by definition, state, address and name, unrequested and historical collections stay unknown, and Ghidra seeds fold instances after the definitions.
* feat(il2cpp): accept --generic-instances on the CLI and describe it in tool contracts
* docs(il2cpp): describe generic method instances and their limits
* fix(il2cpp): keep issued generic rows unknown and name their row
A method spec that contradicted the metadata still reported its pointer slot as code, while the schema and provider limitation promised unknown. Such rows now keep no address, every issue carries its genericMethodTable row, the domain validator requires unknown exactly on issued rows, and shared specs name one other row instead of all of them. The row-size lower bound moves to the metadata admission owner, the hex helper is shared, and budget wording says checked rather than reserved.
* test(il2cpp): reject ambiguous generic layouts and pin budget, yield and limit paths
* fix(il2cpp): keep unmapped generic slots per row and reject undeclared arguments
Layout selection no longer requires every genericMethodPointers slot to be
mapped; each row reads its own slot, so one unmapped slot leaves only that
row unknown with an issue. Method specs whose class or method argument count
differs from the owner's declared generic container are issued and unnamed.
Fixtures now declare the containers their generic rows fill.
* fix(il2cpp): page generic method issues instead of retaining them in summaries
Summaries keep generic_methods without its issues and count them in
counts.generic_method_issues; the generic_method_issues collection pages
them by rows, indices and fields, as code_gen_modules already does. Docs
also name the method_indices filter the request schema accepts.
* fix(il2cpp): read split generic arguments per slot and method containers on demand
Generic argument arrays may span adjacent loader ranges: admit them with
hasPointerArrayCoverage and read each slot through readPointer, instead of
requiring the whole array in one mapping.
Method generic container indices are read on demand from the method record,
like type containers, so no link path allocates a per-method column. An owner
whose container index is out of range now leaves the method spec unnamed with
an issue instead of naming it unchecked.
* fix(il2cpp): report generic entries past the address space at their row
A damaged methodSpecs or genericMethodPointers pointer could make a spec or
slot address exceed 64 bits. The issue kept that address, which the address
schema rejects, so inspection failed instead of leaving the row unknown.
Check the entry range first and attach the issue to the genericMethodTable
row (or its slot field).
* chore(il2cpp): remove unrelated formatting changes
* fix: restore adb float pattern and mobile fixture from main
The merge commit's lint-staged run rewrote these two main files: oxlint --fix
dropped the escape in [+\-], which is invalid under the RegExp v flag.
* fix(il2cpp): preserve unreadable generic method identities
* docs(il2cpp): record generic-instance workflow verification
* docs(il2cpp): qualify final integration checks
