morlutoandHenglie 92dadf9334 fix(domain): preserve partial reference comparison facts
Own endpoint identity and per-edge kind knowledge in one parsed reference
representation. Preserve exact same-artifact coordinates and cross-artifact
name uncertainty, including generated and nonunique procedure labels.

Use exact multiplicity-preserving sparse compatibility flow instead of
positional/greedy pairing or a quadratic adjacency matrix. Share the native
coordinate parser with call paths and remove the superseded projections.

Validate public MCP comparison/reconstruction outcomes, independent tiny
permutation oracles, dense matching and advertised JSON Schemas.

Kaoru0822andClaude Opus 5.5 847b7328cf fix(comparison): keep unnamed reference endpoints distinct or unknown (#3809)
* fix(comparison): keep unnamed reference endpoints distinct or unknown

compare_functions projected reference endpoints to procedure names only,
so two edges whose targets had no named procedure both became null and
compared equal, even when their recorded addresses differed.

Identify an unnamed endpoint by its address when both dossiers describe
the same artifact, where that address names one location. Across
artifacts the endpoint has no stable identity, so equal-looking
projections that contain one leave the references dimension unknown
with an explicit limitation. Named endpoints still survive relocation.

Fixes #3388

* fix(comparison): report known reference-kind changes before unnamed-endpoint uncertainty

Compare known reference kinds first and keep a differing kind as a
change; the unnamed-endpoint limitation now applies only when equality
remains unproven. The kind projection uses the same endpoint identity
as the endpoint projection.

morluto 55dd21a5e2 fix(native): retain partial format facts and explicit coverage
Preserve XML and Interface Builder identity at their parsing boundary, retain usable Objective-C slots with precise coverage, and keep native trace failures distinct from absence. Add caller-selected Interface Builder summaries backed by complete retained Evidence, and preserve comparison limitations.

Validation: relevant native/domain focused lane passed 142 tests; earlier Interface Builder/MCP checks passed 24 tests. Real native UI and Ghidra producer coverage was not repeated.

8823c55b0c feat(ghidra): decode Swift String literals in function dossiers (#2049)
* feat(ghidra): decode Swift String literals in function dossiers

Swift passes a String as two words. Small literals keep their UTF-8 bytes
inside those words, and immortal large literals keep a count plus a pointer
to their bytes biased by 32. Ghidra creates no data reference for either, so
analyze_function reported no strings for Swift code.

On AArch64 programs that contain Swift metadata, the Ghidra bridge now runs
constant propagation over the function and decodes register pairs where
Swift consumes a String: consecutive argument registers at calls and tail
calls, x0 and x1 at returns, and both registers of one STP. Large literals
must resolve to terminated bytes inside one initialized block that is not
executable. A pair whose registers both come from conditional selects is
skipped, because Ghidra forks each select without correlating the
condition and could otherwise pair words from different cases.

Decoded values are a derivation from the ABI layout rather than observed
references, so they appear in a new optional swift_string_literals field
with their source instruction, registers and raw words, and in a matching
inspect_analysis_view facet. referenced_strings is unchanged.

Refs #2030

* fix(ghidra): bound Swift literal reads and compare decoded strings

Large immortal literals are measured against the remaining heap before
allocation, and a failed fit stays visible as a limitation. The canonical
empty string is kept. Small and large literals now require matching
address nullability, and function comparison treats decoded literals as
string evidence without equating a missing record to an empty one.

* fix(ghidra): budget Swift literal decoding and tighten use sites

Large literals now draw on one heap budget per dossier, measured once
before decoding, instead of a separate check per literal. A literal that
does not fit is listed in a new swift_string_literal_omissions field
with its address, byte length and reason, so consumers read omissions
from structured data rather than from limitation text.

strings_names comparison checks referenced strings and names first and
reports a change there even when Swift literal coverage differs; it
returns unknown only when those facts match and literal coverage is
absent on one side or partial.

A computed jump counts as a tail call only when it has no resolved
target inside the function, so jump tables no longer qualify, and a
return requires a RETURN p-code operation, so traps no longer qualify.

Decoded literals keep control characters, which Swift strings may
contain and JSON escapes. The Swift verifier builds the literal fixture
for arm64 on any Mac host and now also covers the empty string and a
literal containing a tab.

* fix(ghidra): charge escaped JSON and follow copied selects

The Swift literal budget now charges the worst case per UTF-8 byte: UTF-16
text, six escaped JSON characters held in Gson's growing buffer and in the
returned String, and the UTF-8 bytes written to the socket. Literals made
of control characters can no longer exceed the reserved heap.

A jump counts as a tail call only when every resolved target lies outside
the function. The conditional select check follows register copies back
to their definition, so selects copied into argument registers are
recognized like selects written there directly.

strings_names reports a change when both dossiers decoded different
literals at the same use site, even when either side has omissions; it
returns unknown only when no such use site disagrees.

* fix(ghidra): bound literal records and trace selects across branches

Every Swift literal record now pays a fixed cost against the dossier
budget in addition to its text, so many empty or small literals are
bounded as well. The first record that does not fit is kept as an
omission and decoding stops there, which keeps the omission record
itself bounded; omissions now describe small or large literals.

The conditional select check searches every predecessor path for the
reaching definitions, following register copies, so selects made
before a branch into the use block are recognized.

A dossier records Swift literals and their omissions together. Coverage
reads omissions first, and strings_names compares every use site that
neither side omitted: a decoded literal is known where it was recorded,
and an absence is known only in a dossier whose decoding examined every
use site.

* fix(ghidra): stop every flow at the literal budget and route omissions

Ending one flow from the evaluator leaves other queued flows running, so
the budget now records a shared stop that every flow checks before it
examines another instruction. A record that exceeds the budget is routed
by that capacity result rather than by whether text was decoded, so a
small literal over budget becomes an omission instead of a literal.

When coverage is partial, the per site comparison keeps each literal's
representation as well as its value, matching the full strings_names
projection.

* fix(ghidra): keep unresolved Swift tail-call sites unknown

morluto 049132ab43 fix(evidence): preserve call coverage in function comparisons
Treat missing, partial, unknown, and unresolved call coverage as insufficient for call-set equality. Combine IDA caller/callee coverage without losing either explanation and recheck source coverage when verifying historical comparisons.

Scope generated function-comparison unknowns with optional typed comparison/dimension facts, preserving legacy IDs and revision digests when absent. Keep unrelated dimensions conclusive, explicit dependencies applicable, and ambiguous function identity unknown. A confirmed change for matched functions remains a failure even if calls are incomplete.

Validation: function/reconstruction/residual-unknown and bundle tests, recorded IDA protocol regression, public MCP comparison/verification, and advertised SDK JSON Schema checks. Real IDA provider execution was not verified.

Fixes #2222

Compare complete function dossiers directly, remove unreachable truncation and collection wrappers, and preserve deterministic Unicode ordering. Require real external reference targets instead of display placeholders.

BREAKING CHANGE: function comparison results no longer advertise the unreachable truncated state or counter.
