static/style.css is 51,425 lines in one file. Hundreds of selectors are
declared more than once and !important is used throughout, so the rendered
result is a function of source order. Extracting a block into its own file
changes that order, and nothing in the suite would notice - which makes a
51k-line split unfalsifiable and "looks fine to me" the only available
evidence.
This moves no CSS. It captures getComputedStyle over a fixed inventory of
676 elements across three pages, four viewports, both themes and the three
density modes - 16,224 element snapshots - hashes them, and compares against
tests/css_snapshot/baseline.json. A capture takes about 21 seconds.
The bench page synthesises one element per selector from an evidence-driven
list: every selector declared more than once in style.css that can be
expressed as a static compound chain, plus a curated set per feature area.
Redeclared selectors are the ones a reorder can flip. The bench loads
whatever stylesheets index.html ships, so it keeps measuring the real set
once the file is split. tests/test_css_computed_style_snapshot.py also carries
a self-test that swaps two conflicting .attach-strip declarations and asserts
the digest moves, so the harness cannot silently stop watching.
The second half is the asset-manifest check specs/frontend.md asks for,
scoped to stylesheets: every stylesheet referenced by shipped HTML and by the
sw.js precache exists, and index.html and sw.js agree on the ?v= string. They
hardcode it independently today, so a split that updates one and not the
other ships an offline cache nobody notices until a plane.
_terminate_owned_chrome() walked Path("/proc") unconditionally, so on macOS
and Windows iterdir() raised FileNotFoundError out of private-browser session
shutdown. src/tools/cookbook.py already guards the same kind of scan with
os.path.isdir("/proc").
The sweep only reclaims Chrome trees that agent-browser reparented, so it is
an optimisation rather than a correctness requirement: degrade to a no-op
rather than failing the whole shutdown path.
_PROC_ROOT is a module attribute so both branches are testable on either kind
of host. The procfs-present path had no coverage at all before this.
The R09 scholarly hardening routes every hop through check_outbound_url with
block_private=True. On a DNS64/NAT64 network, an IPv4-only host can resolve
through the RFC 6052 Well-Known Prefix. For example, export.arxiv.org resolved
to 64:ff9b::924b:5b2a in the reproduced environment.
CPython classifies that outer IPv6 prefix as reserved, so the URL guard rejected
the request before examining the effective IPv4 destination.
Decode addresses in exactly 64:ff9b::/96 to their embedded IPv4 destination and
evaluate that destination under the strict outbound policy.
The translated target is always checked with private-address blocking enabled.
This prevents the NAT64 prefix from becoming a path to loopback, private,
shared/CGNAT, link-local, multicast, unspecified, or other non-global IPv4
space.
Network-specific translation prefixes are not decoded. In particular,
64:ff9b:1::/48 remains subject to the existing IPv6 policy.
Coverage includes:
- public IPv4 destinations embedded through the RFC 6052 prefix
- loopback, link-local, private, CGNAT, multicast, unspecified, benchmark, and
TEST-NET rejection
- network-specific NAT64 prefixes remaining undecoded
- deterministic scholarly provider tests without live DNS dependence
- redirect query parameter isolation
- relative redirect resolution
- HTTP error fallback behavior
- editor draft GET and DELETE behavior remaining unaffected
R09, R11, and R01 were independently audited and otherwise left unchanged.
static/style.css is 51,425 lines and holds every panel's styles, so two
people working on unrelated panels still edit the same file. This is the
first of three steps that give each panel group its own stylesheet. It moves
the document library, image gallery and image editor rules that can move
into static/css/documents-gallery-editor.css.
The new file is loaded eagerly from index.html immediately after style.css,
so the cascade is the concatenation of the two in that order, which is the
order those rules already had. Nothing is deferred and nothing renders
differently.
Rules moved verbatim. A rule stays in style.css when its selector group
covers more than one panel, when the class is shared design language used
from modules outside the panel, or when moving it would flip which of two
equally specific rules wins on an element the markup puts both classes on.
That last rule is what keeps this change small: most panel-prefixed rules on
this branch compete with a shared component rule somewhere later in the file.
Nineteen tests read static/style.css directly and go red the moment a rule
they assert on moves, which says nothing about the page. They now go through
tests/helpers/stylesheets.app_css(), which concatenates the stylesheets in
the order index.html loads them. The helper also exposes the <link> markup
for tests that build a synthetic page through Playwright.
- Enforce outbound URL policy on all hops via bounded manual redirects in scholarly lookups
- Guard declared Content-Length in EditorDraftRoute before request body parsing
- Keep scholarly lookup timeouts and budgets as internal constants rather than surface env vars
- Narrow TUI threat-model description around demonstrable host shell bridge behavior
- Add behavioral regression tests for redirect security and pre-parsing body size guards
Covers both behaviours end to end: a refused outbound URL and an exhausted
budget must skip the request entirely rather than fall through to httpx, the
remaining budget caps each hop's timeout, and an over-ceiling Content-Length
returns 413 without the body being parsed.
Verified against the pre-fix tree: the User-Agent was hardcoded, the endpoints
were literals, check_outbound_url was absent, both hops carried independent
12.0s timeouts, and an oversized declared body returned 422 after parsing
rather than 413 before it.
