Accept (+) button:
- Was reading raw storage (getStorageData) which returns encrypted
blobs when encryption is enabled, silently failing to add mappings
- Fixed: adds directly to the local mappings array and persists via
setStorageData (storage bridge handles encryption transparently)
Auto-detect false positives:
- Was only checking identity values, not explicit mappings — values
already in the mappings table still got flagged as unconfigured PPI
- Fixed: now adds all mapping real/substitute values to the skip set
Ignore button:
- Changed from plain text link to grey pill button for better UX
- Still persists permanently via ss_ignored_ppi in storage

The early hook approach (inline script, then external early-hook.js)
kept breaking Firefox due to CSP restrictions and timing issues with
the async external script load. Each fix for ChatGPT introduced a
new regression for Firefox/Brave.
Reverted to the original simple approach:
- Injector reads storage, injects content.js via <script src="...">
- content.js captures window.fetch at load time and patches it
- No inline scripts, no early hooks, no __ssOriginalFetch globals
This is what worked on Claude.ai across all browsers before the
ChatGPT fix attempts. ChatGPT support may need a different approach
later (possibly using declarativeNetRequest for header-only changes,
or a ChatGPT-specific content script), but it should not break the
core functionality on Claude.ai.
Kept the Request object handling in the fetch interceptor (needed for
some frameworks) but removed all early hook dependencies.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Bug 1 - Reveal mode not working (all browsers):
sessionSubstitutions stored "ademo demo" (full name) as key, but
buildRevealPairs looked up "ademo" and "demo" individually. No match,
no reveal pairs, reveal did nothing. Fixed by also storing individual
words from multi-word replacements so both "ademo demo" AND "ademo"
AND "demo" are in the map.
Bug 2 - Missing await on _handleDecryptedMeta (sync.js):
Two call sites returned the Promise instead of the resolved value.
Downstream code checking decResult.data got undefined. Added await.
Bug 3 - Profile selector broken by safeHTML (popup.js):
DOMParser.parseFromString wraps content in <html><body> which
mangles <option> elements when moved to a <select>. Replaced with
new Option() DOM API which creates proper option elements.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
The fetch interceptor was loaded via <script src="content.js"> which
is asynchronous. ChatGPT's Next.js framework stores a reference to
the original fetch() during module initialization — before our script
finishes downloading. By the time content.js patches window.fetch,
ChatGPT is already using its stored copy of the original.
Fixed with a two-step injection:
1. Injector injects a tiny INLINE <script> (synchronous, instant)
that stores the real fetch/XHR references and installs a thin
proxy. This runs before ANY page JavaScript.
2. Content.js loads normally, uses the stored __ssOriginalFetch
reference, and registers __ssInterceptFetch so the proxy can
route future calls through the full substitution engine.
This ensures the fetch hook is in place before frameworks like
Next.js, React, or any SPA framework can save a reference to
the original fetch().
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
ChatGPT (and potentially other AI services) calls fetch() with a
Request object as the first argument: fetch(new Request(url, opts))
instead of fetch(url, opts). The interceptor only handled the second
form, so ChatGPT's conversation requests passed through unmodified.
Fixed by handling both fetch signatures:
- fetch(url, options) — existing path
- fetch(Request) — new: extracts URL, method, headers, reads body
via request.text() for JSON/text content types
Also handles non-string body types:
- Blob → text via blob.text()
- ArrayBuffer → text via TextDecoder
- URLSearchParams → string via toString()
These cover the various ways modern frameworks call fetch().
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Proper noun detection (flagging capitalized phrases like "Getting
Started", "Generate Design", "Introduction Getting Started") now
disabled by default. Enable via popup → Options tab → Detect proper
nouns.
The pattern-based detection (IPs, emails, API keys, addresses, paths,
etc.) remains always-on and reliable. The capitalized phrase heuristic
was producing too many false positives on normal UI phrases, headings,
and instructions — adding words to the filter was a losing game.
Added detectProperNouns toggle to popup Options tab.
Updated README to note it's opt-in.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Fixed safeHTML in all three files — template.content.childNodes and
doc.body.childNodes are live NodeLists that shrink as nodes are moved.
Using Array.from() to create a static copy before spreading into
replaceChildren().
Expanded proper noun common words filter with ~500 additional verbs,
nouns, and adjectives (generate, design, manage, process, account,
button, dashboard, etc.) to prevent false PPI flags on titles,
headings, and UI button labels.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Massively expanded the common words filter — added ~500 common verbs,
nouns, and adjectives that frequently appear capitalized in titles,
headings, UI buttons, and instructions. 'Generate Design', 'Create
Account', 'Search Filter', etc. are no longer flagged as PPI.
Updated both content.js and auto-detect.js with the same word list.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
sessionSubstitutions stored keys as toLowerCase() for lookup, but the
lowercase key was also used as the substitute value when building
reveal pairs. This caused unrevealText to replace "John Smith" with
"ademo demo" instead of "Ademo Demo".
Fixed by storing both the original-case substitute and the original
real value in sessionSubstitutions. The lowercase key is still used
for lookup, but the preserved-case value is used for reveal pairs.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
When reveal mode was turned OFF, text stayed showing real data
(e.g. "John Smith") instead of reverting to the AI's actual text
("Ademo Demo"). The unreveal function relied on a WeakMap of
original text nodes which lost entries when DOM nodes were replaced
during streaming responses.
Fixed by replacing WeakMap-based restore with active reverse
replacement: unrevealText() replaces real→substitute (the opposite
direction of revealText). This is reliable regardless of DOM changes.
Removed originalTexts WeakMap entirely.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
1. Removed data_collection_permissions from Firefox manifest — it
requires Firefox 140+ but we target 128+. Only produces a warning
when missing, not a blocking error.
2. Fixed JS syntax error in content.js line 450 — two extra closing
braces from a bad merge in the proper noun detection function
caused a parse error that blocked Mozilla validation.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Replaced all 31 innerHTML assignments across popup.js (12),
options.js (17), and content.js (3) to pass Mozilla AMO linter.
Each file gets a safeHTML(el, html) helper:
- popup.js/options.js: DOMParser-based (extension page context)
- content.js: <template> element pattern (page world context)
Empty innerHTML clears replaced with el.replaceChildren().
innerHTML += replaced with createElement + safeHTML + appendChild.
All event listener bindings after HTML rebuilds remain functional
since safeHTML uses replaceChildren() which populates DOM
synchronously before querySelectorAll + addEventListener calls.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
The X icon looked like a dismiss/close button (temporary). Changed to
a small 'IGNORE' text link that clearly communicates the action is
permanent — the value will never be flagged again.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Proper noun heuristic:
- Changed from matching any single capitalized word to requiring
TWO OR MORE consecutive capitalized words (e.g. "Acme Corp")
- Single capitalized words at sentence starts were causing massive
false positives — every sentence starts with a capital letter
- Minimum 5 characters total and 2 proper words required
Ignore button:
- Each PPI warning item now has an X (ignore) button alongside
the + (add mapping) button
- Ignored values are persisted to storage (ss_ignored_ppi) so
they stay dismissed across page reloads
- Ignored values are skipped in both pattern detection and
proper noun detection
- Clicking ignore removes the item from the warning and re-scans
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Reveal mode's text replacement was walking ALL text nodes on the page
including contenteditable elements (the chat input box on Claude.ai,
ChatGPT, etc.), overwriting the user's typed text with garbled
revealed content.
Fixed by adding contenteditable checks to:
- revealInElement() — returns early if element is contenteditable
- unrevealInElement() — same
- highlightMatches() — TreeWalker filter rejects contenteditable nodes
- MutationObserver — skips addedNodes and characterData mutations
inside contenteditable elements
All four code paths now use parent.closest('[contenteditable="true"]')
to detect and skip chat input areas.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Removed ZIP read/write complexity. All document formats now extract
text and upload as plaintext — the AI extracts text from files anyway,
no need to preserve formatting in a file the user never gets back.
Added support for: DOC, XLS (old binary), ODT, ODS, ODP (OpenDocument),
PPTX (PowerPoint), RTF.
Extraction methods:
- PDF: content stream operators (Tj, TJ)
- DOCX/XLSX/PPTX/ODT/ODS/ODP: ZIP XML text extraction with DEFLATE
- DOC/XLS: UTF-16LE and ASCII text run extraction from binary
- RTF: strip formatting commands, keep text
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
DOCX and XLSX files now get actual text substitution, not just
scan-and-warn:
- Reads the ZIP structure (DOCX/XLSX are ZIP files of XML)
- Decompresses DEFLATE entries via DecompressionStream API
- Finds XML text content between tags
- Applies substituteAll() to each text node
- Rewrites modified entries as uncompressed (stored) in new ZIP
- Unmodified entries preserved with original compression
- Rebuilds central directory and end-of-central-directory record
DOCX targets: word/document.xml, word/header*.xml, word/footer*.xml,
word/comments.xml, word/endnotes.xml, word/footnotes.xml
XLSX targets: xl/sharedStrings.xml, xl/worksheets/sheet*.xml
Formatting, styles, images, formulas all preserved — only text
content between XML tags is modified. Preview mode still shows
findings before upload for user confirmation.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
New module: document-scanner.js
- PDF: extracts text from content streams, scans for PPI, converts to
sanitized plaintext for upload (PDFs can't be reliably edited in-place)
- DOCX/XLSX: extracts text from XML entries, scans for PPI
- Text files: direct string substitution
- Handles scanned/image-only PDFs gracefully (skips with message)
Fetch interceptor (content.js):
- Now intercepts FormData uploads (file uploads) in addition to JSON
- Processes each file through document scanner
- Preview mode for PDF/DOCX/XLSX: shows PPI findings with counts,
user clicks "Substitute & Upload" or "Upload Original"
- Text files substituted silently (no preview friction)
- String form fields also substituted
- 30-second auto-dismiss on preview (uploads original if no response)
Preview UI (content.css):
- Centered overlay with dark theme matching existing warning UI
- Shows original → substituted pairs for each PPI found
- File format note (e.g. "PDF will be converted to plain text")
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Import parser:
- Passwords now imported from Chrome/Firefox/Bitwarden/1Password CSVs
as exact-match auto-redacted mappings (→ [REDACTED-PASSWORD-N])
- Catches passwords in any context, not just key=value patterns
Proper noun heuristic:
- Auto-detect scanner now catches capitalized words mid-sentence as
potential names, company names, or project names
- Filters against 200+ common English words, programming terms, days,
months to reduce false positives
- Added to both content.js (page world) and auto-detect.js (popup)
README:
- Documented proper noun detection with examples
- Documented bulk import with all supported formats
- Added Sync features section (auto sync, conflict resolution,
version history, connected devices)
- Added Organization/Team section with policy format
- Added tamper protection documentation
- Added Legal section with liability analysis
- Updated architecture with all new modules
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Sync encryption:
- AES-256-GCM encryption for all sync channels (browser sync, gist,
custom URL, folder sync, sync codes)
- Password with optional TOTP (RFC 6238) second factor
- Configurable auth TTL: session, 30/90/180/365 days, or never
- CryptoKey cached in IndexedDB — auth only needed when cache expires
AND new data exists (lastModified check runs before auth prompt)
- WebAuthn (biometric/PIN) as low-friction re-authentication gate
- Full options UI for setup, password change, and inline auth prompt
Smart reveal:
- Track which substitute values were actually sent outbound per session
- Reveal mode only replaces values that were genuinely substituted,
preventing false positives (e.g. AI using the word "user" won't be
replaced with a real username that maps to "user")
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
PPI + button fix:
- After adding a mapping, the real PPI value is now immediately replaced
with the fake value in the input/contenteditable element via the new
replaceInInput() helper (handles both <textarea>/<input> and
contenteditable divs by walking text nodes).
- Triggers a re-scan 150ms later so the pre-send warning updates or
dismisses itself if no more PPI remains.
Auto-sync folder (File System Access API):
- User picks a folder once per browser via "Choose Sync Folder".
Any settings/mappings/identity change writes silent-send-sync.json
to that folder automatically (via api.storage.onChanged listener).
- On options page open and every time the page regains focus, the file
is read back; if its lastModified is newer than local data, settings
are imported immediately and the UI refreshes.
- File handle is stored in IndexedDB (ss_sync_handles) so it persists
across browser sessions without repeated permission prompts.
- Pick the SAME folder in each browser (or a synced cloud folder for
cross-computer sync) — fully automatic after that, no copy-paste.
- sync.js gains saveSyncDirHandle / loadSyncDirHandle / clearSyncDirHandle
helpers backed by IndexedDB.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Bug fixes:
- Date (possible DOB) pattern now requires context words (born, birthday,
dob, etc.) before firing — prevents spurious warnings on page-load API
calls that happen to contain ISO dates in conversation history.
- Highlight regex now uses word boundaries (\b) so short substitute values
(e.g. "aud") no longer match inside unrelated words like "Claude".
- Both TreeWalkers in content.js now skip the extension's own UI elements
(.ss-autodetect-warning, .ss-presend-warning, .ss-reveal-badge) to
prevent the highlight API from marking text in the extension's banners.
Settings sync:
- New src/lib/sync.js: exportSyncCode / importSyncCode (base64 JSON) for
manual copy-paste across any browser combination. Newest lastModified
timestamp wins; force flag available to override.
- browser.storage.sync support: when "Browser account sync" is enabled the
extension automatically pushes/pulls via Firefox Sync or Chrome account,
chunked to stay within per-item quota limits.
- storage.js now writes ss_lastModified on every save so conflict resolution
has an accurate timestamp.
- service-worker.js listens for both local and sync storage changes to keep
all copies in sync.
- New "Sync Between Browsers" section in options.html with Generate/Copy/
Import Sync Code UI and the browser sync toggle.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Detected PPI is now auto-redacted in the fetch hook using
RFC/standard reserved values — not just warned about:
- IPs → 192.0.2.1 (RFC 5737 TEST-NET-1, never routed)
- MACs → 00:00:00:00:00:00
- Addresses → 123 Example Street, Anytown, ST 00000
- GPS → 0.000000,0.000000 (Gulf of Guinea)
- Dates → 01/01/1970 (Unix epoch)
- EINs → 00-0000000 (impossible prefix)
- Paths → /home/user
- Git → example org
These are obviously fake and guaranteed not to be real data,
unlike random values which could be confused with actual PPI.
New Options toggle: "Auto-redact detected PPI on send" (on by
default). When on, PPI is caught in the fetch hook even if the
user hits Enter immediately after pasting. Warning banner now
says "Auto-redacted with standard placeholders" instead of
"These were sent as-is."
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Like spellcheck for privacy. Scans text as you type and paste
into chat inputs (debounced 800ms). Shows a dark floating warning
panel listing detected PPI BEFORE you hit Enter.
Each detected item has a green [+] button that instantly:
1. Generates a plausible fake value (random IP, fake address, etc.)
2. Adds it as a mapping to storage
3. Shows a checkmark to confirm
The warning disappears when you clear the text or when all
detected items have been addressed.
Three new Options toggles:
- Auto-detect unconfigured PPI (on by default)
- Offer to auto-add detected PPI (on by default)
Also adds a storage bridge (postMessage) so the page-world
content script can read/write chrome.storage through the
injector.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Scans outbound messages AFTER all substitutions for personal data
the user forgot to configure:
- Private/public IP addresses (skips 127.0.0.1, 8.8.8.8, etc.)
- MAC addresses
- Street addresses ("123 Main St")
- GPS coordinates
- Dates (possible DOBs)
- EIN/tax IDs
- Home directory paths not caught by smart patterns
- Shell prompts (user@host)
- Git remotes (reveals username/org)
- Environment variable assignments (HOME=, USER=, etc.)
Shows a floating dark warning banner (top-right, auto-dismisses
after 15s) listing each detected item with its type, value, and
hint. Skips values already in the user's identity config.
Also shows PPI warnings in the popup Test tab and adds toggle
in Options to disable auto-detect.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Two visual modes using the Highlight API (zero DOM modification):
- Yellow highlight: fake/substituted values the AI received.
Shows automatically in all AI responses, even without reveal mode.
"The AI sees these yellow values, not your real data."
- Terminal style (black bg, green text): your real data shown
in reveal mode. "This is YOUR data — the AI never saw this."
Uses CSS.highlights with ::highlight() pseudo-elements — no
spans, no DOM changes, no copy/paste artifacts. Falls back to
CSS class-based styling if Highlight API is unavailable.
Highlights are debounced (500ms) to handle streaming responses
without excessive reflows.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Revealed values are now wrapped in <span class="ss-revealed">
with a blue underline and subtle blue background, making it
obvious which parts are your real data vs what the AI said.
Hover shows tooltip "Substituted value: [fake]" so you can see
what the AI actually received. Un-reveal properly removes the
spans and normalizes text nodes.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Storage issue: Chromium/Brave keeps storage.local data even when
an unpacked extension is removed and reloaded. Added "Reset
Everything" button in Options → Danger Zone that clears all data
(double-confirm to prevent accidents).
Reveal mode: Now re-runs revealAllResponses() every 2 seconds
while active to catch streamed content and dynamically loaded
responses. Adds console logging for reveal toggle state changes
to aid debugging. Cleans up interval when reveal mode is turned off.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Interception is now completely inactive until the user configures
at least one identity field or explicit mapping. Before that:
- Icon shows gray (unconfigured)
- No fetch/XHR hooks fire
- First-run banner tells user to set up
Custom domains: clicking "Add Domain" in Options now triggers
the browser's native permission prompt via permissions.request().
No more manual chrome://extensions site access step.
Icon states are now:
- Gray = unconfigured (nothing will happen)
- Black = active and protecting
- Blue = reveal mode on
- Red = manually disabled
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Adds a secret scanning layer that runs after identity/explicit
substitutions. Catches secrets the user didn't configure:
- API keys: OpenAI (sk-), Anthropic (sk-ant-), Google (AIza),
AWS (AKIA), GitHub (ghp_), GitLab (glpat-), Slack (xox),
Stripe (sk_live/test), SendGrid (SG.)
- Auth: Bearer tokens, key=value assignments (password=, secret=,
api_key=, token=), private key blocks (-----BEGIN PRIVATE KEY-----)
- Connection strings: mongodb://, postgres://, mysql:// with creds
- PII: SSN (xxx-xx-xxxx), credit card numbers (Visa/MC/Amex/Discover)
Redacted values shown in red in the Test tab. Secrets are truncated
in the activity log (first 8 chars + "...") to avoid logging the
full secret. Enabled by default, toggle in Options.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Replace URL-pattern and body-shape matching with universal approach:
Outbound (substitution):
- Hooks ALL POST/PUT/PATCH fetch and XHR requests, not just known
API endpoints. Skips static assets and analytics.
- Deep-walks any JSON structure recursively to find and substitute
all string values. Skips metadata keys (model, id, token, etc.).
- Falls back to raw string substitution for non-JSON bodies.
Inbound (reveal):
- Walks ALL text nodes in document.body, not just specific CSS
selectors. Skips SCRIPT, STYLE, INPUT, TEXTAREA tags.
- Handles streaming by observing characterData mutations globally.
This makes Silent Send survive any API restructuring — the only
thing that could break it is a site encrypting request bodies in
JS before fetch, which would also break their own dev tools.
Performance: reveal pairs are cached and only rebuilt on config
change. Deep walk skips known non-content keys to avoid touching
auth tokens or request metadata.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Reveal mode (eye icon) now works as intended:
- Toggle ON: all existing responses on the page get fake→real
substitution applied immediately (paths, names, emails, etc.)
- Streaming responses are revealed in real-time as they arrive
- Toggle OFF: original text is restored from saved state
- Covers code blocks, artifacts, pre tags, and all response
containers across all supported services
- Blue floating badge shows "Reveal Mode — showing real data"
when active so user knows what they're seeing
The workflow is now: type /home/jsmith/... → Claude sees
/home/ademo/... → Claude responds with /home/ademo/... →
reveal mode shows /home/jsmith/... → user copies real path.
Also adds privacy note in popup footer: data stays in local
browser storage, no servers, no tracking, no analytics.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Test tab now has two modes:
- Strip (real → fake): paste text with real data, see what gets sent
- Reveal (fake → real): paste AI output with fake data, get back
real data with a "Copy to Clipboard" button
Also fixes:
- content.js smartSubstitute bailing when identity.enabled was
undefined (defaulted enabled to all-true instead of returning)
- Test tab now reloads identity from storage on tab switch so
changes saved in the Identity tab take effect immediately
- Shows yellow warning when identity fields are missing
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Extend Silent Send to intercept API requests on all major AI chat
services. Each service has different API shapes:
- ChatGPT: /backend-api/conversation with content.parts arrays
- Grok: GraphQL + /2/grok/add_response with message field
- Gemini: form-encoded f.req with nested arrays (+ generateContent)
- OpenWebUI: /api/chat and /ollama/api/chat (self-hosted)
All services share the same substitution pipeline. Manifests updated
for both Chrome and Firefox with host_permissions for all domains.
OpenWebUI supported via localhost/127.0.0.1 for self-hosted instances.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
jsmith@macbook-pro now becomes ademo@mycomputer when both username
and hostname are configured in the Identity tab. Hostnames are also
caught standalone (e.g. just "macbook-pro" in text).
Also rewrites README with detailed step-by-step Mozilla API key
setup instructions for Firefox signing.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Instead of requiring explicit mappings for every variation, users
now configure their identity once (Identity tab) and Silent Send
auto-catches:
- Emails: any address @gmail, @yahoo, @outlook, etc.
- Names: first/last, full name, reversed, possessives, case variants
- Usernames: user@host, ~user, /home/user, C:\Users\user
- Phones: all common formats ((555) 123-4567, 555.123.4567, etc.)
Smart patterns run before explicit mappings, so explicit rules
can override smart catches when needed.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Chrome Manifest V3 extension that intercepts personal data and
substitutes it with user-defined replacements before sending to
Claude.ai. Hooks fetch() in the page's main world to catch API
requests, with bidirectional substitution (real→fake on send,
fake→real on display via reveal mode).
Includes popup UI with mapping management, live test/diff view,
activity log with badge count, options page with import/export,
and Shadow DOM traversal for Claude.ai compatibility.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
