+# Browser audit fixes
+
+This work addresses the browser review of `bf4b9d7` against local Orca. The first
+implementation batch fixes the four reproduced defects and two navigation costs.
+It also adds busy live-region deferral. It does not establish complete Orca parity.
+
+## Implemented behavior
+
+- Crossing objects validates dirty hypertext ancestors, because parent-owned text
+  can change embedded offsets without changing accessible child identities.
+  A failed move preserves the position; the refreshed retry reads the insertion.
+  A local character move within an unchanged child still avoids recapture.
+- Atomic updates read the enclosing atomic region for both text changes and child
+  additions. The source's effective `container-atomic` metadata gates this path.
+  Chromium exposes `atomic=false` on ordinary descendants, so those default values
+  do not terminate the ancestor walk.
+- Table movement crosses missing cells, including neighbors in lower rows of a
+  spanning cell. It uses captured cells rather than iterating huge sparse row or
+  column dimensions. Real blank cells remain stops. Table validation and lookup
+  operate on the table subtree and its ancestors, preserving refreshes for changed
+  coordinates, headers and cell data while allowing unrelated page updates.
+- Word movement skips whitespace using blocks of at most 128 native Unicode
+  characters. Only observed whitespace triggers this path, so ordinary word and
+  character movement do not gain an extra block request. Native word boundaries,
+  spelling metadata and embedded-object limits retain their existing handling.
+- The cursor indexes object-to-range positions once per immutable document view.
+  A hypertext object can have multiple ranges, and lookup preserves their actual
+  traversal order. Retired views rebuild both the ranges and their index.
+- Busy live regions defer updates until their busy flag clears. The GLib owner
+  keeps at most 32 region/document identities, without retained native references
+  or intermediate text. Completion rereads the active region and enters the live
+  insertion path, without acquiring focus or producing document-loading speech.
+  Secure input, tab selection, object destruction, document lifecycle and shutdown
+  retire the relevant deferred state. Live attributes are fetched together once
+  per candidate event, after foreground filtering.
+
+The browser must expose accurate live attributes. A diagnostic Chromium fixture
+which set `aria-busy=true` and replaced descendant text in the same JavaScript
+turn reported `container-busy=false` on the initial descendant event. Cthulhu
+cannot reliably defer an update which the provider reports as not busy. The
+retained regression establishes busy state before the initial accessibility
+capture and proves that clearing the flag alone releases the deferred content.
+Nested explicit atomic=false boundaries likewise depend on correct effective
+`container-atomic` metadata from the provider.
+
+## Automated evidence
+
+The AT-SPI, review and app packages passed with the race detector. The full race
+run failed in `internal/sound` at
+`TestNewPresentationInterruptsOldCueAndDiscardsPendingCues` with “stale link cues
+remained queued.” Ten isolated repetitions also reproduced that failure in an
+untouched snapshot of `bf4b9d7`; the sound files were not changed. This remains an
+existing gate, so the full suite is not described as passing.
+
+Thirteen selected Chromium fixtures passed in a private X11/D-Bus session:
+`generatedlinks,replacement,fragments,namedlinks,linkedheadings,tables,selection,modes,document,editing,tabs,live,live-atomic`.
+The final `live-atomic` run also verifies that busy completion requires no new text
+insertion. It covers atomic text updates, atomic child additions, non-atomic
+updates, suppression while busy, and release after busy becomes false.
+
+Firefox baseline reading passed. Its tab regression timed out on the second
+“New Tab” announcement in both the modified checkout and an untouched `bf4b9d7`
+snapshot. The recorded events include a selected-state event for the previous
+unselected tab. This is an unresolved existing/provider case, not a verified
+regression introduced by these changes.
+
+The affected `go vet` checks, normal reader build, BrlAPI helper build, Python
+syntax check, parity-ledger validation and whitespace check passed. No installed
+reader was replaced. The native fixtures record protocol/snapshot behavior;
+they do not prove audible output or physical keyboard/Braille acceptance.
+
+A counting reader crossed 1,000 whitespace characters with three word commands
+using 39 reads, including 16 character-block reads. The old implementation used
+1,003 reads for a single forward word command. This is an API-call count, not a
+measurement of audible latency.
+
+Three 100 ms synthetic benchmark repetitions still show character round trips
+near 12 microseconds at 10,000 content nodes. Allocation traffic remains about
+16 KB per character round trip and 52 KB per worker heading round trip. These
+runs overlapped other checks and are informational, not a controlled timing
+comparison. They exclude native IPC, initial capture, speech and physical input.
+
+Run the relevant checks:
+
+```sh
+python3 tests/native_test_session.py env GOCACHE=/tmp/cthulhu-cache go test -race ./internal/atspi ./internal/review ./internal/app -count=1
+CTHULHU_NATIVE_BROWSER_TESTS=live-atomic,generatedlinks,replacement,fragments,namedlinks,linkedheadings,tables,selection,modes,document,editing,tabs,live python3 tests/native_browser.py
+python3 tests/native_firefox.py
+go vet ./internal/atspi ./internal/review ./internal/app
+go run ./cmd/parityledger validate testdata/parity-ledger.csv
+```
+
+## Human acceptance before submission
+
+Review the generated diff under the project's AI-assisted contribution policy.
+With an explicitly rebuilt reader, test these workflows in Chromium and Firefox:
+
+1. Read forward and backward through links and changing text between them. Read
+   All must include inserted text once and continue through generated links.
+2. Check atomic status updates retain their surrounding label, non-atomic updates
+   announce the change, and busy updates wait for the completed region.
+3. Navigate ragged and merged-cell tables in all directions. Verify headers,
+   blank cells, logical row/column retention, nested tables and boundary messages.
+   Repeat with an unrelated page ticker and then a changed cell/header.
+4. Move by word through long indentation, tabs, newlines and Unicode whitespace.
+   Check reverse movement, emoji, named links, and character-by-character spacing.
+5. Type/select in an editor; return from the address bar and another tab; check
+   Steam browsing/search; verify stale targets never activate replacement controls.
+   Compare speech and physical Braille where available.
+
+Do not submit or replace the active reader automatically. Preserve logs if a
+workflow fails and distinguish provider metadata from reader-owned state.
+
+## Remaining review work
+
+The user authorized addressing the whole review, in priority order. On October
+24, the maintainer prioritized stabilizing the current release before adding
+new functionality. MathCAT was left to implementation judgment and is deferred
+with the other feature additions below. Release work should concentrate on the
+existing fixes, the recorded test failures, and live acceptance. These items
+remain open and must not be reported as implemented:
+
+- Automatic language switching, including language runs within a line, native
+  focus, structural navigation, character reading and Read All. The current
+  speech queue and client selection do not carry per-content language metadata.
+- Structured math speech, Braille and exploration. MathCAT's maintained C
+  interface provides a shared engine, but adds a Rust-built library and its rule
+  data to packaging. No MathCAT dependency has been added in this batch.
+- Constrained label inference for controls without an accessible name or explicit
+  label relationship. Keep explicit labels authoritative and reject ambiguous
+  neighboring text. This is a deliberate presentation-policy addition.
+- Demand-driven capture for pages exceeding the 30,000-object safety bound.
+  The bound and whole-document initial capture remain unchanged. A partial tree
+  must represent unloaded branches explicitly so it cannot silently report false
+  end-of-document or incomplete element lists as complete results.
+
+MathCAT integration should keep Go as the policy owner, use the upstream C ABI,
+serialize engine state on a dedicated worker, and preserve browser responsiveness
+when the engine or rules are unavailable. Revisit dependency and packaging choices
+after the current release is stable; no MathCAT dependency is being added now.
