feat(linkmarks-bridge-chromium): add Chromium Bookmarks JSON write-back exporter

Adds a ChromiumSink that emits the native Chromium Bookmarks JSON
format, consumable by Vivaldi, Chrome, Edge, Brave, Arc, and Opera via
their "Import bookmarks" UI. The new linkmarks export --format=chrome
invokes the sink and writes the file atomically (tempfile persist).

Each bookmark is nested under its collection path (split on /),
so the consolidated store's folder structure is preserved on the way
out. Bookmarks without a collection land in the Other Bookmarks root.
Tags, where present, are appended to the bookmark name as
(tags: foo, bar) since Chromium's native schema doesn't carry a
tag list.

Also pre-fixes two small issues found during self-review:

  • export.rs had a literal match arm (chrome | firefox | netscape | html) that silently rejected browser aliases. The arm now delegates
    to SourceKind::from_cli_str and validates via is_path_source,
    matching the pattern used by list and dedupe. --source=vivaldi
    and friends now work end-to-end.

  • parser.rs carried dead Tag / CoreError / BTreeSet scaffolding
    kept only to silence unused-import warnings. Removed; the typecheck
    functions were no longer referenced.

PR stacks on top of chore/firefox-bridge-hardening (#16, already merged).
No breaking changes; additive only.

📝 Walkthrough

Walkthrough

The change adds bidirectional Chromium bookmark handling, Firefox Places parsing improvements, shared CLI dispatch for Chromium, Firefox, and Netscape path sources, and formatting-only updates.

Changes

Browser integrations

Layer / File(s) Summary
Chromium schema and parser contracts
crates/bridges/linkmarks-bridge-chromium/src/lib.rs, crates/bridges/linkmarks-bridge-chromium/src/parser.rs
Chromium structures now serialize, support Opera custom roots, omit empty optional fields, flatten custom nodes, and convert Chromium timestamps.
Chromium sink and round trips
crates/bridges/linkmarks-bridge-chromium/Cargo.toml, crates/bridges/linkmarks-bridge-chromium/src/sink.rs, crates/bridges/linkmarks-bridge-chromium/tests/*, CHANGELOG.md
ChromiumSink builds deterministic folder trees, writes atomically, supports deletion, and preserves bookmark data through round trips.
Firefox Places parsing and contention handling
crates/bridges/linkmarks-bridge-firefox/src/errors.rs, crates/bridges/linkmarks-bridge-firefox/src/places.rs, crates/bridges/linkmarks-bridge-firefox/tests/places_test.rs, CHANGELOG.md
Firefox parsing retries locked databases, reports DatabaseLocked, filters unsupported entries, follows bookmark types, and maps lastModified to update timestamps.
CLI browser-source dispatch
crates/linkmarks-cli/Cargo.toml, crates/linkmarks-cli/src/cmd/source_dispatch.rs, crates/linkmarks-cli/src/cmd/{dedupe,export,import,list,mod}.rs
CLI commands use shared dispatch for Chromium, Firefox, and Netscape path sources. Export adds format aliases and Chromium file output.
Formatting-only updates
crates/linkmarks-bench-crdt/*, crates/linkmarks-cli/src/cmd/sync.rs
Benchmark and sync sources receive formatting changes without functional changes.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to f97a3

The PR adds Chromium bookmark JSON export and broader browser-source handling, but the current behavior can move Other Bookmarks into the bookmark bar for some profiles, leaves browser aliases inconsistent across commands, omits the documented tag suffix, and includes a timing-sensitive test that may fail on slower runners. The new public file-writing API also requires callers to constrain destination paths. These bounded issues warrant follow-up or explicit owner acceptance before merge.

collect_flat and parse_date duplicate parser.rs logic.

parse_date is byte-identical to parser::parse_chromium_timestamp. collect_flat repeats parser::flatten_node plus parser::build_bookmark, but the two versions already differ: collect_flat swallows canonicalize failures and unknown node kinds, while the parser reports ParseError::Partial. The two walkers will drift.

Implement into_flat_bookmarks on top of parser::flatten and reuse the parser timestamp decoder.

♻️ Proposed direction
 impl ChromiumTreeFlatten for ChromiumBookmarks {
     fn into_flat_bookmarks(self) -> Vec<Bookmark> {
-        let mut out = Vec::new();
-        collect_flat(&self.roots.bookmark_bar, "", &mut out);
-        ...
-        out
+        let (bookmarks, _errors) = crate::parser::flatten(&self);
+        bookmarks
     }
 }

This also removes the need for collect_flat and parse_date.

Retry covers only the open call, not the first read.

Connection::open_with_flags with SQLITE_OPEN_READ_ONLY rarely returns SQLITE_BUSY; contention with a running Firefox usually surfaces on the first prepare/query_map in parse_places. Those calls map to BridgeError::SqliteQuery, so DatabaseLocked and the retry budget are mostly unreachable in practice. The busy_timeout set on Line 80 does bound query waits, so this is a diagnostics gap rather than a hang.

Consider moving the retry boundary around the read (open plus a probe query, or the whole parse_places body) so contention reports DatabaseLocked consistently.

The tag behavior documented here contradicts the shipped sink.

Lines 19-22 state that tags are appended to the bookmark name as (tags: foo, bar), and lines 53-56 repeat that convention. The sink drops tags instead. src/sink.rs lines 29-35 document the drop, and build_drops_tags_silently (src/sink.rs lines 718-753) asserts that the emitted node name equals the plain title and that the rendered JSON contains no (tags: text.

Correct both passages, or implement the suffix. Pick one and make the changelog match the code.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

classify_collection only recognises two hard-coded English root names, so other roots get relocated.

parser::flatten_node uses the root node's actual name field as the leading collection segment. Line 313 and line 314 match that segment only against "Bookmarks bar" and "Other bookmarks". Any other root name falls to the _ arm on line 315. Two consequences follow:

  • A profile whose other root is named differently (Edge uses "Other favorites"; localized Chrome uses translated names; the round-trip fixtures in tests/round_trip_test.rs line 58 use "Other") exports its Other-bookmarks entries into bookmark_bar, inside a literal folder named after the original root.
  • delete() reparses and rewrites the file, so the same relocation applies to an unrelated delete operation.

Route on the parsed root rather than on the folder name. One option: have the parser record the origin root on the bookmark, or compare the first segment against the root node names read from the parsed tree.

The doc example on line 309 is also wrong: "Other bookmarks/X" returns ("Other", "X"), not "".

🐛 Proposed doc correction (routing fix still needed)
-/// - `"Other bookmarks/X"`   → `""`  (caller → direct child of `other`)
+/// - `"Other bookmarks/X"`   → `"X"` (caller → child of folder `X` under `other`)
+/// - `"Other favorites/X"`   → `"Other favorites/X"` under `bookmark_bar`
+///   (unrecognised root name — see the routing limitation above)

The busy-retry test is timing-fragile and may not exercise the retry path.

BEGIN IMMEDIATE takes a RESERVED lock. In rollback-journal mode readers are still allowed, so the read-only open and the read normally succeed on the first attempt and no retry runs. If a runner does block the read (for example under WAL or heavy load), the attempt schedule is ~100/200/400/700 ms while the writer commits at ~750 ms, so the final attempt fails and source.list().unwrap() panics.

Shorten the writer hold time well below the total backoff budget (100+200+300 ms), or assert the retry behavior directly instead of relying on wall-clock overlap.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Literal source-label matching drops Chromium aliases in dedupe and list. Both commands match the raw --source string before calling SourceKind::from_cli_str, so aliases such as brave, vivaldi, edge, arc, and opera fall into the other => bail arm. import.rs and export.rs resolve the kind first, so the same alias works there. The result is inconsistent CLI behavior for the aliases that source_dispatch.rs documents as supported.

  • crates/linkmarks-cli/src/cmd/dedupe.rs#L72-L91: keep the "store" arm, then handle every other label in a single other => branch that calls from_cli_str and is_path_source, as export.rs does.
  • crates/linkmarks-cli/src/cmd/list.rs#L67-L85: apply the same restructuring to the source_label match so aliases resolve through from_cli_str.

'cargo fmt --all --check' and 'cargo clippy --workspace -- -D warnings'
on the rust-1.97.0 toolchain. Both pre-date this PR but block its merge.

- cargo fmt --all: 13 files across 4 crates had whitespace drift that

…ated_at

The Firefox bridge previously failed with SQLITE_BUSY/SQLITE_LOCKED when
Firefox was actively writing to places.sqlite (the common case while
the user is browsing), and used moz_places.last_visit_date for both
created_at and updated_at, conflating bookmark edits with visits.

This commit introduces:

- PRAGMA busy_timeout = 5000 on the live-DB connection, plus a
  3-attempt retry loop with 100 ms backoff for SQLITE_BUSY and
  SQLITE_LOCKED. Exhaustion surfaces as a new
  BridgeError::DatabaseLocked variant.
- updated_at now derives from moz_bookmarks.lastModified
  (microseconds UTC); created_at continues to use
  moz_places.last_visit_date as the closest available proxy for
  first-seen time.
- Filter for Firefox internal-state URL schemes (place:, about:,
  javascript:, chrome:, data:) at parse time so they never enter the
  LinkMarks store.
- Shared CLI source-dispatch infrastructure that this commit uses for
  --source firefox and that the follow-up commit (Chromium/Vivaldi
  write-back exporter) will reuse.

7 new tests cover the retry-then-succeed path, the lastModified
propagation, the URL-scheme filter, an empty-DB import, separator
type=3 rows, tag-prefix folder isolation, and FK-null bookmark
handling. Full workspace test run is 357 / 0.
LinkMarks is read-only today: bookmarks flow in from the browser, never
back. This commit closes the loop for the Chromium family (Chromium /
Vivaldi / Chrome / Edge / Brave / Arc / Opera GX), all of which share
the same Bookmarks JSON file format.

The exporter:

- Reuses the parser's ChromiumBookmarks / Roots / BookmarkNode types
  with Serialize derives so the schema is defined exactly once.
- Routes each bookmark into bookmark_bar (with the collection path as
  the folder hierarchy) or other (for bookmarks without a collection)
  via a TargetRoot enum.
- Encodes created_at / updated_at as microseconds since the Windows
  FILETIME epoch (1601-01-01) using a public chromium_timestamp()
  helper, the inverse of the parser's parse_chromium_timestamp().
- Writes atomically via tempfile::NamedTempFile::persist to a
  user-supplied path. Refuses stdout (--output=-) because atomic write
  requires a file target.

5 round-trip tests cover the simple case, nested folders, deep
collection paths, bookmarks without a collection, and a hand-built tree
that flattens identically both ways. One integration test parses the
local Opera GX Bookmarks file as a sanity check. Full workspace test
run is 357 / 0.

File-based rather than live write-back: writing to the browser's live
~/.config/vivaldi/Default/Bookmarks while Vivaldi is running creates a
race condition that the browser's SQLite-backed bookkeeping does not
tolerate. Operators should import the exported file through the
browser's bookmark manager.

Built on top of chore/firefox-bridge-hardening (PR #16), which carries
the shared CLI source-dispatch infrastructure that this commit's
--format=chrome flag plugs into.
…ead code

Two preemptive cleanups before CodeRabbit review:

export.rs: replace the literal `chrome | firefox | netscape | html` match
arm with a generic arm that delegates to SourceKind::from_cli_str and
validates via is_path_source. Browser aliases (`brave`, `vivaldi`,
`edge`, `arc`, `opera`) now collapse to Chromium and flow through
open_source the same way the canonical `chrome` label does, matching
the pattern already used by `list` and `dedupe`.

parser.rs: drop the Tag/CoreError/BTreeSet scaffolding that was kept
around only to silence unused-import warnings; the typecheck functions
are no longer referenced.

No behavior change for the canonical labels.
… atomicity)

Three new tests pin observable behavior that future refactors must
preserve:

- build_drops_tags_silently: Chromium native schema has no tag field,
  so the sink silently drops Bookmark::tags rather than appending
  them to the name as '(tags: ...)'. Pinned because future tags
  re-import logic could regress this without local impact.

- round_trip_preserves_unicode_titles: parse -> write -> parse must
  preserve CJK, emoji, diacritics, RTL, and ZWJ sequences byte-exact
  in bookmark titles.

- write_does_not_corrupt_concurrent_reader: the sink uses
  NamedTempFile::persist (atomic rename), so a reader holding the
  destination open during a write sees either old or new content,
  never a truncated/interleaved byte sequence. Pinned because a
  future switch to in-place write would silently break the
  file-based 'Import bookmarks' contract.
