* fix(browser): move cookie scoping off psl's stale suffix list
psl@1.15.0 is its latest release and ships a Dec-2024 snapshot of the
public suffix list. Measured against the current upstream list, it fails
to recognise 600 of 10,030 suffixes; tldts misses 2.
That gap is a cookie-isolation bug. psl does not know `api.br` is a
suffix, so it falls back to the `br` rule and maps foo.api.br, bar.api.br
and example.api.br all onto the single family `api.br`. Unrelated
registrants then share a removal scope, and a replace-mode import for one
clears the others' cookies. The same holds for seg.ar, co.az, gov.cz and
~597 more.
tldts is called with allowPrivateDomains, without which the PSL's PRIVATE
section is ignored and every *.github.io / *.s3.amazonaws.com / *.vercel.app
tenant collapses into one family — 21 of 49 probed hosts changed family
under the default. The new test pins that boundary.
One deliberate behaviour change: hosts under `.local` (not in the PSL)
were their own family under psl, which returned an all-null parse for
them; they now resolve to the two-label boundary (app.orca.local ->
orca.local), matching what Chromium treats as the registrable domain.
* fix(build): bundle tldts into the main process like psl was
psl sat in BUNDLED_MAIN_DEPENDENCIES, so it was inlined into the main
bundle rather than externalized and copied into resources/node_modules.
Swapping the dependency without moving that entry left a bare tldts
import that afterPack's runtime-closure check rejects.
* fix(build): point the output contract at tldts and drop the psl shim
The contract test still asserted psl was in BUNDLED_MAIN_DEPENDENCIES, so
it failed once the entry became tldts. src/types/psl.ts declared a module
that no longer resolves; tldts ships its own types.
* test(browser): pin the suffix boundaries the tldts swap moved
Three semantic changes shipped untested:
- `.local` is unlisted, and the libraries disagreed on what that means. psl
returned an all-null parse so every `*.orca.local` host was its own family;
tldts stops at `orca.local`. The consequence is wider than the family name —
importDomainAncestors now yields the shared parent, so a replace-mode import
of one host clears non-host-only cookies every sibling shares.
- psl's snapshot had `compute.amazonaws.com` as a literal PRIVATE suffix; the
current list only carries the wildcard, so the bare host is ICANN now.
- The renderer's `psl.isValid` gate had no direct test at all — nothing imported
the module from a test.
Also drops comments that explained a boundary in terms of psl's internals. One
was wrong under tldts: bracketed IPv6 does not reach an error branch, it parses
with the brackets stripped and falls through the unlisted path.
