The verifier and the builder each resolved the profiles a run names, in
thirty-five lines that differed only in how they failed: one exits, the
other returns empty-handed. An alias is the same binary under another
name and a launcher only starts an emulator, so neither has requirements
of its own, and both refusals have to say the same thing.
common raises now and each caller chooses its own ending. Six tests hold
the refusals, one of them reading both sources so a copy cannot grow
back. The manifest's core-complement phase comes out of generate_manifest
in the same pass, 60 to 34.
Verified inert: manifests identical entry for entry, and the Handy pack
rebuilds to the same bytes.
Resolving the profiles a run names, which refuses an alias or a launcher
because neither has requirements of its own, and the structural checks
on an archive that hold whatever it contains: a duplicate entry, an
absolute path, a traversal, a zero-byte member. Complexity 58 to 50 and
63 to 51.
Extracting the second surfaced a Counter it had been reading from the
enclosing module, which pyflakes caught before the tests did.
find_undeclared_files decided per entry whether a core requirement can
be a gap, through a chain that mixed two skips whose difference is easy
to lose. Some record the requirement as settled so no other profile
reconsiders it; the rest leave it open, because the same file can be
libretro-only in one profile and standalone-only in another and the key
carries no emulator.
The chain returns a named verdict now, complexity 60 to 45. Twelve tests
cover the verdicts and two more cover the distinction end to end: a
standalone-only entry seen first must not answer for the profile that
needs the file. Collapsing the two skips into one passes every other
test in the suite and fails that pair.
The markdown report wrote to a directory named after the tooling that
happened to produce it. It takes --report-dir now, defaulting to
reports/, so nothing in the tree names anything but the project.
Em-dashes replaced throughout the sources and tests, rephrased rather
than swapped for a comma where the dash carried an apposition.
Four sites still compared the verification mode to a literal after the
module owning that policy existed. One of them mattered: an unrecognised
mode fell through to MD5 verification while compute_severity was scoring
it as existence, so a typo in a platform YAML produced a report whose
checks and severities described different platforms.
The mode is normalized once per run and the consumers ask for what they
need. A test reads the sources and fails on a literal comparison, so the
next consumer cannot quietly grow a fifth copy.
The builder and the coverage report each grouped their own candidates
before asking which regional alternatives to withdraw. The builder
grouped the platform files and the core extras; the report grouped the
platform files alone, and keyed them on an unsanitized destination.
So a region run withdrew 73 files from a recalbox pack while the report
withdrew 14, and described the other 59 as covered by a pack that would
not carry them.
platform_region_groups builds the grouping once and both sides read it.
The extras it returns are keyed by emulator, name and path: Dolphin
declares three IPL.bin that differ by path alone, and a name-keyed map
withdraws the wrong one. Manifests are byte-identical before and after.
The gap analysis answered from the name index, so a core extra whose
local copy contradicts its declared hash counted as held. Under a
digest mode the builder drops exactly that file, so the coverage report
described a pack that would not contain it: seven files across
Batocera, Recalbox and RetroBat.
An entry that states what its content should be is now resolved by
content; the name still answers for entries that declare nothing to
check against, and existence mode is unchanged because there the
frontend never opens the file and the pack does carry it.
The per-emulator report counted an entry nobody can supply -- a
per-user key, a slot the user fills, a dump that was never made -- as
plainly missing. fpse-ng read 14 missing when twelve were documented as
unobtainable, which invites the wrong repair: dropping the flag,
deleting the entry, or chasing a vendor's whole install tree.
They are listed with the reason the profile records rather than hidden,
and the summary counts them apart. Platform reports are untouched.
The per-emulator report captured the status resolve_local_file returns
and then ignored it: any non-empty path became OK. An entry whose only
candidate contradicts its declared hash therefore read as covered, so a
same-named file from another system stood in for one the collection
does not hold. 36 entries across 14 profiles were affected, among them
config.ini, ROM and rom2.bin, names that collide across systems.
Emulator validation still runs first, since it names the field that
disagrees; the resolution status is consulted only when validation had
nothing to say.
verify.py and generate_pack.py must reach the same verdict on the same
file, and CLAUDE.md calls any divergence critical, but each spelled out
mode == 'existence' in its own words. Both now ask nativemode whether
the frontend reads the file's bytes, which is the one fact the rest
follows from, and a test holds the two answers together.
The BaseScraper contract the wiki asks contributors to implement had no
caller anywhere, so nothing proved compare_with_config, has_changes or
test_connection still worked.
A declared hash that the local dump contradicts is not one situation. An
existence platform never reads the bytes, so withholding the file lets an
upstream list error remove something the frontend would have loaded; a
hash platform would reject it, so shipping it is pointless.
The mode now decides, at every point that had an opinion: pack building,
core complement, emulator packs, manifests, conformance and
_intentional_hash_exclusion. verify.find_undeclared_files follows, since
verify and generate_pack must agree file for file.
Also here: resolution reports which evidence matched rather than a flat
"exact", a path or filename can no longer override a declared hash, and
safe_extract_zip treats a Windows backslash as the separator it is
instead of refusing the archive.
