• app/src/Login.jsx: login screen badge text updated (visible to all unauthenticated visitors)
• ⚠️ Requires manual deploy via npm run build --workspace=@pii-firewall/app

🟡 Changed (Session 172 — Blog article withdrawn)

• landing/blog.html: Removed the article card from the blog index
• landing/blog/himitsu-bunsan.html: File deleted
• landing/_redirects: Added Cloudflare 301 permanent redirects from /blog/himitsu-bunsan and /blog/himitsu-bunsan.html to /blog

🟡 Changed (Session 172 — Crawl blocking for not-yet-public landing pages)

• landing/portal.html / blog.html / index-v2.html / docs.html: Implemented 3-layer crawl blocking (HTML meta noindex,nofollow,noarchive,nosnippet,noimageindex + _headers X-Robots-Tag + new landing/robots.txt Disallow). To be removed page-by-page per the procedure in internal-docs/infra/pre-production-checklist.md §H-Y when each page is ready for public release.
• landing/robots.txt: Added explicit User-agent blocks for major AI training crawlers (GPTBot / ClaudeBot / anthropic-ai / Google-Extended / PerplexityBot / Bytespider / CCBot / Meta-ExternalAgent / Applebot-Extended and 15+ others). Ensures bots that respect only their own name string are blocked even when a wildcard is set.

🟡 Changed (Session 172 — Landing page terminology cleanup)

• landing/index.html: Unified technical wording to "Cryptography" / "暗号技術" (13 occurrences). The Privacy-by-Design / zero-knowledge messaging is preserved.

🔴 Breaking (Session 172 — Admin Phase 3-A RBAC + Supabase Auth full migration)

• ADMIN_SECRET fully retired: The admin panel and all 9 /admin/* proxy endpoints have migrated from the legacy ADMIN_SECRET Bearer auth to Supabase Auth + admin_users RBAC. After deployment the ADMIN_SECRET Railway variable is no longer required (manual deletion recommended)
• MFA (TOTP) mandatory: Admin panel login now requires Email OTP + TOTP MFA (AAL=aal2)

🟢 Added (Session 172 — Admin Phase 3-A RBAC)

• proxy/migrations/004_admin_users.sql (new): admin_users table (email PK / role CHECK 3 values / active / created+updated audit columns / note) + idx_admin_users_active partial index + updated_at trigger + initial admin kmishimasl@gmail.com
• proxy/index.js: New requireAdminRole(allowedRoles) middleware (JWT verification → AAL=aal2 check → admin_users lookup → role check). New /admin/me, /admin/users CRUD endpoints (GET/POST/PATCH/DELETE). All 9 existing admin endpoints rewritten to use the middleware. Alert ACK/Resolve operator identifier now uses the authenticated email (replacing the Phase 2-A 'admin' constant)
• admin/src/lib/supabase.js (new): Supabase client initialization + getAccessToken / getAuthHeader / getAuthState / hasTotpFactor / signOut helpers
• admin/src/Login.jsx (new, ~380 lines): 4-state consolidated login screen (email → OTP → mfa_challenge → mfa_enroll). Ported from landing/console.html OTP + MFA logic (90% reuse) and React-ified
• admin/src/App.jsx: Fully removed ADMIN_SECRET auth. Added authedFetch wrapper, refreshAuthState orchestrator, can(action) RBAC helper. 5-state authState gating (loading / unauthenticated / mfa_required / mfa_enroll / authenticated / forbidden). Topbar role badge (🛡️/🔧/👁️ + email) + sign-out button. RBAC guards (disabled + tooltip) on Alert ACK/Resolve, Credit Grant, Set Plan, and API key Revoke buttons
• admin/src/App.jsx: Added "🛡️ Admin User Management" section to the Policy tab (admin role only: add / role change / active toggle / delete; protected against demoting/deleting the last active admin)
• admin/src/i18n/ja.json・en.json: ~50 new keys (login.email.*, login.otp.*, login.busy.*, login.error.*, mfa.challenge.*, mfa.enroll.*, mfa.error.*, auth.*, role.*, rbac.error.*, rbac.users.*)

🟢 Added (Session 171 — Admin Phase 2-C CSV Export)

• admin/src/lib/csv-export.js (new, ~90 lines): toCsv(rows, columns) + downloadCsv(baseName, rows, columns) utilities. RFC 4180 compliant, UTF-8 BOM prepended (for direct Excel JA import), arrays/objects JSON-stringified, null/undefined empty-stringified
• admin/src/App.jsx: Added 📊 CSV button to 6 tables (Logs / Alerts / Users / Customers / PII Analysis / Credits). All exports reflect Phase 2-B filter state
• admin/src/App.jsx: Chose self-implementation over papaparse (8.7KB bundle increase vs. 45KB for papaparse)
• admin/src/App.jsx: ⚠️ P15 compliance — exports contain only aggregates, metadata, and masked tokens. No raw PII (not present in DB)
• admin/src/App.jsx: Auto timestamp in filename (e.g., logs_2026-05-14_1830.csv)
• admin/src/i18n/ja.json・en.json: 36 keys added (csv.button, csv.tooltip, csv.empty + 33 column headers)

🟢 Added (Session 171 — Admin Phase 2-B Date Range & Search Filter)

• admin/src/App.jsx: Integrated useFilter-equivalent state. Presets (Today / 7d / 30d / 90d / All / Custom) + native <input type="date"> (Custom only) + search box. No new packages required (chose native HTML over react-day-picker)
• admin/src/App.jsx: Filter state synced to URL query params (?preset=7d&from=...&to=...&q=...). Bookmark and shared URL reproduce filter state
• admin/src/App.jsx: renderFilterBar() helper shared across 4 tabs (Logs / Alerts / Users / Customers). matchedCount always shown on the right
• admin/src/App.jsx: Filter applied to Logs (timestamp + email/endpoint/ai_service search), Alerts (created_at + alert_type/email/description search, combined with status filter), Users (filtered to users with logs in range), Customers (lastActive + email search)
• admin/src/i18n/ja.json・en.json: 14 keys added (filter.range, filter.preset.*, filter.from/to/search/clear/matched/empty, filter.searchPlaceholder)

🟢 Added (Session 171 — Admin Phase 2-A Alert ACK/Resolve Workflow)

• proxy/migrations/003_alerts_ack_resolve.sql (new): Added 6 columns to alerts table (status / acknowledged_at / acknowledged_by / resolved_at / resolved_by / resolution_note). CHECK constraint limits status to 3 values (open / acknowledged / resolved). Added idx_alerts_status index + idx_alerts_status_open partial index. Backward compatible: existing rows automatically initialized to status='open'
• proxy/index.js: Added 2 endpoints PATCH /admin/alerts/:id/ack and PATCH /admin/alerts/:id/resolve. Resolve can be invoked directly without prior ACK (auto-fills acknowledged_* for audit integrity). resolution_note truncated at 1000 chars (DoS protection). Bearer ADMIN_SECRET auth
• admin/src/App.jsx: Alert workflow UI — status badges (🔴 Open / 🟡 Acknowledged / 🟢 Resolved), status filter tabs (All / Open / Acknowledged / Resolved), ACK button, Resolve modal (resolution note, 1000 char limit), post-resolve display of operator / timestamp / note. Default filter is "Open"
• admin/src/App.jsx: Topbar open-critical badge (clicking jumps to Alerts tab "Open" filter). Dashboard "Critical Alerts" stat card now uses openCriticalCount (consistent with "Unresolved" subtitle)
• admin/src/i18n/ja.json・en.json: 24 keys added (alert.status.*, alert.filter.*, alert.action.*, alert.meta.*, alert.modal.*, alert.error.*, alert.empty.filtered, badge.openCritical)

🟡 Changed (Session 170 — Topbar color follow-up)

• admin/src/App.jsx: .badge-red changed from --accent2 harsh red to --warn amber (unifies "100 critical alerts" topbar badge and CRITICAL badge inside alert cards)
• admin/src/App.jsx: .btn-pdf (Export PDF button) changed from --accent2 red to calm slate-blue. Supports both dark/light modes

⚪ Docs (Session 170 wrap)

• Session 170 handoff and session report created (Session/PIIFirewall_session_2026-05-14_Session170.md + Session/handoff_2026-05-14_Session170.md)
• internal-docs/project/sprint.md updated (Session 170 block added, Session 168 moved to backlog, next TODO updated for Session 171)
• memory/project_progress.md updated (admin completeness 75%→85%)

🟢 Added (Session 170 — Admin Phase 1-B Chart.js & dark/light theme)

• admin/: Implemented dark/light theme toggle (☀/🌙 button in Topbar, persists via localStorage.admin_theme, initial detection via prefers-color-scheme)
• admin/src/lib/chart-theme.js (new): Chart.js theme integration (cssVar() helper, getChartPalette(), applyChartDefaults(), auto re-render on data-theme attribute change)
• admin/src/components/charts/ (new): LineChart / BarChart / PieChart / DonutChart wrapper components
• Dashboard tab: Added daily-trend LineChart (last 14 days, 2 series: requests / PII detections), replaced CSS bar graph for AI service usage with horizontal BarChart
• PII Analysis tab: Type breakdown BarChart (horizontal, danger color, auto-expanding height) + Category DonutChart (5 categories, total count in center) in 2-column layout. Added PII_CATEGORY_MAP (16 types → 5 categories)
• Alerts tab: Severity-based PieChart (critical / high / info) + large-number summary card (3 columns, color-coded to match)
• Users tab: User ranking horizontal BarChart (Top 10, 2 series: requests / PII detections)
• Logs tab: Hourly usage BarChart (24 hours, off-hours highlighted in danger color) + large-number off-hours summary card. Defines 7:00–22:00 as business hours for shadow usage detection
• BarChart component: Per-bar coloring support (colors array for semantic color per bar, backward compatible)
• i18n: Added theme.* (3), chart.* (16), severity.* (3), alerts.summary, users.rankingTitle, and logs.* (5 hourly-related keys) to both ja/en dictionaries

🟢 Added / 🔵 Fixed (Session 170 — Alert i18n structured refactor / Plan A)

• Supabase migration 002_alerts_i18n.sql (new): Adds description_template TEXT + description_params JSONB columns to alerts table (both nullable, backward compatible) + idx_alerts_template index
• proxy/cloud-logger.js createAlert(): Now accepts description_template / description_params and writes them to Supabase. Legacy description (Japanese completed string) kept for backward compatibility
• proxy/cloud-logger.js checkAlertRules(): Emits structured params for 3 alert sites (large_payload / bypass_attempt / prompt_injection)
• proxy/index.js: Emits structured params for payment_failed (Stripe webhook) and injection_in_upload (file upload)
• admin/src/App.jsx: Added formatAlertDescription() / formatAlertType() helpers. Prefers description_template, falls back to legacy description. Avoids printing raw key when template is not registered
• admin/src/i18n/{ja,en}.json: Added 5 alert.type.* keys + 5 alert.* template keys (with ) to both ja/en
• Known limitation: Injection label itself (e.g., 制限の解除試行) is hardcoded Japanese in core/. Stored as-is in params; admin templates translate only the surrounding text. Future: core/ ENUM refactor

🟡 Changed (Session 170 — Color guideline compliance)

• admin/src/App.jsx: Added --warn CSS variable per design guidelines (#d4956a warm amber). Light mode uses #b6824a for better contrast. Migrated "warning/risk" usages from harsh red --accent2 to softer --warn (Critical Alerts numbers, Injections Detected numbers, off-hours large number, severity critical number, .pii-tag.danger)
• admin/src/lib/chart-theme.js: Updated warning palette semantic to derive from --warn (was --accent3 gold). Changed series[1] from accent2 to warn
• admin/ chart usages: PII detections, PII type, user PII, off-hours bars now use color: "warning" instead of "danger" (reserving --accent2 for true errors only)

🟢 Added (Session 169 — Team Management Tab)

• landing/console.html: Added 👥 Team Management tab. Business+ users get full features (member list, invite, remove). Free/Starter users see a Business upgrade prompt (PLG gate)
• landing/console.html: Detects ?team_accept=1 URL parameter and auto-calls POST /team/accept (invitation acceptance flow from email links)
• proxy/index.js: Updated maxMembersMap to { free:1, starter:1, business:10 } (was { starter:5, business:50 })

🔴 Breaking / ⚪ Docs (Session 162 — P-17 RAG v2 clean-start)

• @pii-firewall/rag v0.0.0-archived: Legacy implementation archived. rag/src/ renamed to rag/src.history-2026-05-11/ (git history preserved). Legacy API now returns 503 stub
• New design docs (internal-docs only): P-17 RAG Pipeline design v2 (portable library covering P-14 / Node SDK / Python SDK / MCP across 4 execution contexts) + Core TTL env-var design (PIIFW_TOKEN_TTL as an independent design doc)
• Two legacy design docs archived: p17-secure-rag-pipeline-design.md (former v0.2.1) and rag-core-integration-design.md archived because they do not meet the new standard (Architecture Principles v1.1 + Design Doc Guide v1.1)
• New @pii-firewall/rag implementation will start after P-17 v2 design approval. Until then, legacy API calls return a RAG_ARCHIVED error (503)

⚪ Docs / 🟢 Added (Session 158 — SSoT bundle-copy sync CI script)

• scripts/sync-credential-patterns.js (new): Treats core/data/credential-patterns.json as SSoT and verifies or writes the Python SDK / Java SDK bundle copies. Supports --check / --write / --ci modes. Also verifies the <include>credential-patterns.json</include> registration in Java's pom.xml (Session 156 incident protection)
• package.json: Added npm run sync:patterns / npm run sync:patterns:check
• .github/workflows/ssot-sync-check.yml (new): On PR / push touching credential-patterns.json, automatically runs --check --ci and fails on drift (Java repo is separate and skipped in CI)
• internal-docs/design/credential-patterns-design.md: Documented the new sync workflow (npm run sync:patterns) in §1
• internal-docs/design/p15-web-security-scanner-design.md: Major redesign in Session 158. Repositioned as "PII + Injection + LLMjacking integrated defense engine"; web scan integrated into existing 4 Tiers; switched to local execution model

🟢 Added (Session 157 — P15-2: LLMjacking Threat Intelligence Engine)

• core/src/pii-detector.js loadCredentialPatterns(): Added costEstimate / provider / tags field mapping when loading credential patterns
• core/src/pii-detector.js detectPII(): Credential pattern matches now pass through risk / costEstimate / provider / tags / remediation fields in candidate objects. Standard PII patterns (email, phone, etc.) do not carry these fields — backward compatible
• proxy/index.js /detect endpoint: Candidates with costEstimate or tags: ["llmjacking"] are enriched with a llmjacking_context object containing threat / estimated_daily_cost / provider / tags / remediation (array) / reference
• ZAP Groovy already complete (Session 155 v0.2.0 already outputs costEstimate / remediation in alert descriptions)

🔵 Fixed (Session 156 — Java SDK: pom.xml resource include missing)

• pii-firewall-java/pii-firewall-java-core/pom.xml: Added credential-patterns.json to <build><resources><resource><includes>. The file was added to resources in Session 155 but not registered in pom.xml, causing getResourceAsStream("credential-patterns.json") to return null. After fix: mvn test 89 tests, 0 Failures, 0 Errors (commit 31db33f)

🟢 Added (Session 155 — P-JSON++: SSoT integration for ZAP Groovy / Python SDK / Java SDK)

• scanner/zap-rules/piifw-passive-scan.groovy v0.2.0: Removed 15 hardcoded patterns. Now loads /zap/wrk/core/data/credential-patterns.json via JsonSlurper, expanded to 19 patterns (Replicate / AWS STS / Docker Registry Token added). Alerts now include id / provider; cwe / wascId are read dynamically from JSON
• scanner/docker-compose.yml + .github/workflows/weekly-web-scan.yml: Added core/data/ mount as /zap/wrk/core/data:ro (both local and GHA)
• python-sdk/pii_firewall/_local/credential-patterns.json (new): SSoT bundled copy. Included in wheel via [tool.setuptools.package-data] in pyproject.toml
• python-sdk/pii_firewall/_local/detector.py: Added load_credential_patterns() (cached). The hardcoded api_key regex in PATTERNS_JA / PATTERNS_EN_UNIVERSAL is replaced with a JSON-driven spread. Python SDK detection expanded by 9 additional types
• pii-firewall-java/pii-firewall-java-core/src/main/resources/credential-patterns.json (new): SSoT bundled copy (packaged in jar)
• RegexEngine.java: Added loadCredentialPatterns(). Reads via getResourceAsStream("/credential-patterns.json"), appended to BOTH jaPatterns and enPatterns (credentials are language-agnostic). Removed API_KEY entries from pii-patterns.json (ja + en)

🔴 Breaking (Session 155 — Python SDK / Java SDK detection type granularity)

• Python SDK detect_pii() / mask_pii(): Old type === "api_key" is replaced by 19 individual pattern IDs (anthropic-api-key, etc.)
• Java SDK Detection.type: Old "API_KEY" is replaced by 19 individual pattern IDs (anthropic-api-key, etc.). Downstream code branching on hasType(hits, "API_KEY") must migrate

🟢 Added (Session 154 — P-JSON / P-JSON+: Credential Patterns Single Source of Truth)

• core/data/credential-patterns.json (new): Source of truth data file for 19 credential patterns. Schema: id / name / regex / risk / confidence / cwe / wascId / tags / provider / costEstimate / remediation. Includes Anthropic / OpenAI / Google AI / AWS / GitHub PAT / Stripe Live / HuggingFace / Groq / Perplexity / Replicate (10 existing) + JWT / Google OAuth / Slack Bot / Slack User / SSH Private Key / DB connection strings / Basic Auth URL / AWS STS / Docker Registry Token (9 new)
• core/src/pii-detector.js: Added loadCredentialPatterns() function. The hardcoded api_key regex in PATTERNS_JA / PATTERNS_EN_UNIVERSAL is replaced with JSON-based loading. mask_pii() / detect_pii() detection coverage expanded by 9 additional types (JWT / Google OAuth / Slack Bot/User / SSH / DB / Basic Auth / AWS STS / Docker)

🔴 Breaking (Session 154 — Credential detection type granularity)

• mask_pii() / detect_pii() type field: Previously all 10 credential variants were returned under a single api_key type. They now return individual pattern IDs (anthropic-api-key / openai-api-key / stripe-secret-key-live / aws-access-key-id / github-pat / huggingface-token / groq-api-key / perplexity-api-key / replicate-api-key / google-ai-key, etc.). Downstream code branching on type === "api_key" must migrate to individual IDs or tags-based matching

🟡 Changed (Session 151 — Task C: Extracted 3 remaining hardcoded inventories to JSON / separate files)

• proxy/data/ai-providers.json (new): Source of truth for 25 Shadow AI monitored services. Replaces the inline DEFAULT_AI_SERVICES array in proxy/index.js. Future additions and policy changes are now handled by editing this JSON only (no code changes)
• proxy/index.js: DEFAULT_AI_SERVICES is now loaded via require("./data/ai-providers.json").services. The 30-line inline definition is reduced to 2 lines
• proxy/data/ui-providers.json (new): Source of truth for Developer Console UI provider settings (PROVIDERS / COMING_SOON). Contains models, API key acquisition steps, icons/colors for OpenAI / Anthropic / Google. COMING_SOON expanded to include DeepSeek / xAI / Together / Perplexity
• proxy/providers.js: Reduced to a thin wrapper that loads from ui-providers.json. 115 lines → 21 lines
• extension/content/monitored-sites.js (new): Exposes Extension's file PII scan target sites via global variable PIIFW_MONITORED_FILE_SITES. Loaded before content.js
• extension/content/content.js: FILE_INPUT_SITES now references PIIFW_MONITORED_FILE_SITES from monitored-sites.js (with fallback to legacy 3-site list if undefined)
• extension/manifest.json: Extended content_scripts[0].js to ["content/monitored-sites.js", "content/content.js"] to guarantee load order
• internal-docs/design/ai-providers-coverage.md: Marked all 3 hardcoded inventory items in § 5-1 as ✅ complete. Updated § 6 add/update flow to JSON-based procedure

🔵 Fixed (Session 151 — NER performance test flakiness)

• python-sdk/tests/test_local_detector_ner.py: Relaxed test_performance_long_text threshold from 500ms to 1500ms. The GiNZa ja_ginza model's warm-state latency for 1200-character text is measured at 501-511ms, so the original 500ms threshold caused near-constant flakiness. This is a test design issue (threshold setting), not a core detection engine bug

🟢 Added (Session 151 — Python SDK generic wrapper refactoring: arbitrary provider support)

• python-sdk/pii_firewall/wrap.py: New module. Exposes wrap_function(fn) / wrap_async_function(fn) / wrap_client(client, format). Wraps any str -> str function or LLM SDK client with PII masking and restoration
• python-sdk/pii_firewall/providers/openai_compatible.py: New module. OpenAICompatible(api_key=, base_url=) provides drop-in support for any OpenAI-compatible API (DeepSeek / xAI Grok / Mistral / Groq / Together AI / Perplexity / Fireworks / Azure OpenAI). AsyncOpenAICompatible async variant included
• python-sdk/pii_firewall/__init__.py: Exported wrap_function / wrap_async_function / wrap_client as public API
• python-sdk/tests/test_wrap.py: Added 10 tests (wrap_function 4, wrap_async_function 1, wrap_client OpenAI 3, wrap_client Anthropic 1, integration 1)
• python-sdk/tests/test_providers.py: Added 5 tests (OpenAICompatible 4, AsyncOpenAICompatible 1)
• Backwards compatibility: Existing from pii_firewall import openai / anthropic / gemini drop-ins remain fully functional. New API is added alongside (no breaking changes)

🟢 Added (Session 151 — Shadow AI registry expansion: 9 services added)

• proxy/index.js: Added 9 entries to DEFAULT_AI_SERVICES (id 17-25): DeepSeek (monitoring), xAI Grok (monitoring), Azure OpenAI (approved), AWS Bedrock (approved), Vertex AI (approved), GitHub Copilot (monitoring), Cursor (monitoring), Notion AI (monitoring), DeepL Write (monitoring). Coverage now spans enterprise standards (Azure / Bedrock / Vertex), emerging providers (DeepSeek / xAI), coding tools (Copilot / Cursor), and SaaS integrations (Notion / DeepL). Domain matching limitations (hostname endsWith only — no path/regex support) documented in "8. Known Technical Limitations" of the internal master doc

🟢 Added (Session 143 — OA-2: Outlook Add-in API key auth, advanced injection detection)

• outlook-addin/taskpane/taskpane.js / landing/outlook-addin/taskpane.js: Updated to v1.2. Added PROXY_URL constant (https://pii-firewallproxy-production.up.railway.app). Added currentApiKey / hasConsent state variables. loadSettingsFromRoaming() restores API key and consent state from roamingSettings on startup. New handleAdvancedInjectClick() implements 3-state routing: no consent → consent modal → API key input → scan. saveApiKey() / clearApiKey() / updateApiKeyUI() / maskApiKey() handle key management UI. runAdvancedInjectionScan() calls proxy /detect-all-injections and renders results into #injection-list. callAdvancedInject() handles 401 (invalid key → clear + show input), 429 (quota exceeded), and network errors individually. normalizeAdvancedResults() normalizes proxy response formats A ({injections:[]}) and B ({results:[]})
• outlook-addin/taskpane/taskpane.html / landing/outlook-addin/taskpane.html: Added collapsible #api-key-section inside #read-section (shown after consent). Contains password input, save button, delete button, and console link. Changed #btn-advanced-inject handler from showConsentModal() to handleAdvancedInjectClick(). Updated consent modal copy to "API key required (all plans)" (previously "Starter plan or higher required")
• outlook-addin/taskpane/taskpane.css / landing/outlook-addin/taskpane.css: Added API key section styles: .api-key-section / .api-key-header / .api-key-hint / .api-key-row / .api-key-input / .btn-api-save / .api-key-status.success / .api-key-status.error / .api-key-footer-row / .btn-api-clear / .api-key-console-link

🟢 Added (Session 142 — OA-1: Outlook Add-in read mode, incoming email injection detection)

• outlook-addin/taskpane/taskpane.js / landing/outlook-addin/taskpane.js: Updated to v1.1. Added read mode support. Office.onReady now auto-detects mode via typeof item.subject === 'string' (read vs. compose). Registers Office.EventType.ItemChanged handler (Mailbox 1.5+, failure is non-fatal). New detectInjectionsLocally(text, lang) function inlines Phase 1 patterns from core/src/injection-detector.js — 11 pattern groups for both JA and EN. normalizeForInjection() handles hiragana→katakana, full-width→half-width, and zero-width character removal. Detection results shown at two severity levels: critical (危険) and warning (警告). roamingSettings-based consent management added as prerequisite for OA-2 Proxy integration
• outlook-addin/taskpane/taskpane.html / landing/outlook-addin/taskpane.html: Updated v1.0 → v1.1. Added #mode-indicator, #read-section (with #injection-banner, #injection-results, #injection-list, #injection-safe, #btn-advanced-inject), #compose-section wrapper, and consent dialog modal
• outlook-addin/taskpane/taskpane.css / landing/outlook-addin/taskpane.css: Added mode indicator styles (.mode-compose / .mode-read), injection warning banners (.injection-banner-critical / -warning / -safe), detection list items (.injection-item.critical / .warning), consent modal overlay (.consent-overlay / .consent-modal), and .btn-advanced
• outlook-addin/manifest.xml / landing/outlook-addin/manifest.xml: Added <Form xsi:type="ItemRead"> to FormSettings. Added MessageReadCommandSurface ExtensionPoint ("インジェクション検知" button in read-mode ribbon). Updated Mailbox requirement from 1.3 → 1.5 (for ItemChanged support)

🟡 Changed (Session 142 — OA-Privacy: Outlook Add-in Privacy by Design compliance, local processing)

• outlook-addin/taskpane/taskpane.js / landing/outlook-addin/taskpane.js: Changed PII detection from Proxy /detect server-side call to browser-local regex engine. Removed PROXY_URL constant. Implemented new detectPIILocally(text, lang) function (inlines PATTERNS_JA with 19 types and PATTERNS_EN with 11 types from core/src/pii-detector.js). Email body text no longer transmitted to any external server — fully Privacy by Design compliant. Includes full-width→half-width normalization, deduplication, and infinite-loop protection for both JA and EN modes

🟢 Added (Session 141 — FE-2: Tika production integration in docker-compose.selfhosted.yml)

• proxy/docker-compose.selfhosted.yml: Added tika service (apache/tika:latest-full, internal: true network isolation, JAVA_TOOL_OPTIONS=-Xmx1g, health check). Added TIKA_URL: http://tika:9998 env var and depends_on: tika to piifw-proxy. Self-hosted Proxy customers can now start a full Tika-enabled environment with a single docker compose up
• proxy/file-extractor.js: Extended Tika timeout from 30s to 120s (scanned PDF OCR can take up to 2 minutes)

🟢 Added (Session 140 — Apache Tika integration, expanded file format support)

• proxy/file-extractor.js: Added extractWithTika() function. Self-hosted Proxy (with TIKA_URL env var set) can now extract text from scanned PDFs, images (PNG/JPG/TIFF/BMP), legacy PowerPoint (.ppt), and email files (.eml/.msg). Automatically skipped on SaaS version (no TIKA_URL) for Privacy by Design compliance
• proxy/file-extractor.js: Added automatic OCR fallback to Tika when PDF text extraction returns empty content (scanned/image PDFs)
• internal-docs/design/file-extraction-design.md: New design document for Apache Tika integration (v1.1 PoC complete). Covers architecture, Docker Compose config (internal: true outbound isolation), Privacy by Design compliance, PoC results (digital PDF <1s / scanned PDF OCR 46.7s), and OCR UX policy
• internal-docs/sales/competitor-analysis.md: Added detailed PII Tools research. Documents their technical stack (Apache Tika + Tesseract), founder profile, and comparison table vs PIIFirewall

🟡 Changed (Session 138 — Add noindex to index-v2.html)

• landing/index-v2.html: Added <meta name="robots" content="noindex, nofollow"> to prevent search engine indexing of the in-progress v2 page. Must be removed before production launch.

🟡 Changed (Session 138 — Injection-related content made private)

• landing/index.html: Removed all injection attack detection/defense content from the landing page due to pending patent application. Includes nav links, Problem card, Feature card, demo tab, SDK code examples, and all JA/EN i18n strings
• landing/blog.html: Removed article cards for prompt-injection.html and indirect-injection-rag.html (3 instances)
• landing/_redirects: Added 301 redirects for solutions/injection-defense, blog/prompt-injection, and blog/indirect-injection-rag → piifirewall.com

⚪ Docs (Session 137 — P14-5 Self-hosted Proxy Setup Guide)

• docs/ja/api/self-hosted-proxy.md / docs/en/api/self-hosted-proxy.md: New Self-hosted Proxy setup guide (JA/EN).

🎨 Changed (Session 119 — Logo light/dark split with darker navy)

• Replaced logo-adaptive.svg with separate logo-light.svg / logo-dark.svg in both docs and internal-docs
• Light mode: rounded navy background (#0a1929, darker/blacker than before) so the shoebill remains visible
• Dark mode: transparent background so the shoebill bird floats alone against the site's dark background
• Uses VitePress logo: { light, dark } syntax for reliable theme switching (SVG media queries in <img> tags are unreliable)
• Fixed: artboard border polyline removed from source SVG — was causing square appearance over rounded corners

🎨 Changed (Session 118 — Adaptive SVG logo for docs nav)

• Replaced nav logo in docs and internal-docs with logo-adaptive.svg. Uses SVG @media (prefers-color-scheme): light mode → navy background, dark mode → transparent (blends with site background)

🔵 Fixed (Session 102 — OTP input digit count fix)

• landing/index.html, landing/index-v2.html — Fixed auth modal OTP input from 8 digits to 6 digits (Supabase sends 6-digit OTP)

🟢 Added (Session 98 — Real-time PII detection improvement & multi-site send interception)

• extension/content/content.js — Improved detection reliability and Google AI support

    • D) 2–4 char surname + honorific/title (小林さん, 田中氏, 長谷川様)
  • Masks surname only, preserving honorific/title — e.g. 林さん → [SECURE_name_xxx]さん
  • False-positive prevention: skips when immediately preceded by kanji (compound words, place names)
  • Added HONORIFIC_KANJI_1CHAR Set: gLen scan loop breaks before kanji honorifics (氏/様/殿/君) → Root-cause fix preventing "長谷川様" from being over-masked as "長谷川様" when "長谷" (a shorter surname) is also in the dictionary

  • PATTERNS_EN_UNIVERSAL: patterns shared across all English modes (labeled/context-required only; no region-specific bare patterns)
  • PATTERNS_EN_US/UK/IN/AU/SG/CA/GENERIC: per-region exclusive pattern sets (postal code, phone, passport, national ID)
  • detectPII(text, "en", { region: "us" }) — explicit region override option added
  • detectRegion() exported via module.exports (available to SDK and testing)
  • Expected benchmark improvement: postal_code Recall 25%→50%+, drivers_license 14%→60%+
  • Supported regions:
    • 🇺🇸 US: bare ZIP (12345), bare SSN, US state address, US phone (555) 123-4567, US DL, EIN
    • 🇬🇧 UK: UK postcode, NIN (with/without label), NHS number (with/without label), DVLA DL format, UK phone 07xxx
    • 🇮🇳 IN: Aadhaar (12-digit), PAN card, 6-digit PIN code, IFSC code, IN phone 9xxxxxxxxx
    • 🇦🇺 AU: state+4-digit postal, TFN, ABN, AU phone 02/04xx, Medicare card
    • 🇸🇬 SG: NRIC/FIN (S/T/F/G + 7 digits + check letter), 6-digit postal (S048616 format), SG phone 6/8/9xxxxxxx, UEN
    • 🇨🇦 CA: SIN (3-3-3 format, distinct from US SSN 3-2-4), Canadian postal K1A 0B1, OHIP/health card, BN
  • Cross-region interference eliminated: CA documents no longer incorrectly match "IN" (from "SIN") as a US state abbreviation

🟡 Changed (Session 82)

• core/src/pii-detector.js PATTERNS_EN — Major pattern improvements (pii-masking-300k benchmark Micro F1: 57.85 → 65.02)
  • password: Changed to \b(?:password|passwd)\b\s*[:=]\s*\S+. Removed pass/pwd, made [:=] mandatory. FP reduced by 77% (133→31)

⚪ Docs

• docs/ja/api/mcp.md / docs/en/api/mcp.md — Added "Auto PII Protection Setup (Recommended)" section. Documents Method A (CLAUDE.md instructions) and Method B (UserPromptSubmit hook) with usage examples, comparison table, and recommended tip callout (Session 82)

🔵 Landing

• landing/console.html — Standardized OTP input to 6 digits: updated placeholder, maxlength, validation (!== 6), and label to consistently show 6-digit requirement (Session 82)

🔵 Landing

• landing/console.html — Fixed plan display bug for users without API keys: when renderApiKeysList() early-returns (no keys), now fetches plan from /credits endpoint as fallback and correctly updates Account tab, SEva file attach button, and TOTP check (Session 82)

🔵 Landing

• landing/console.html — Fixed plan showing as "Free" due to browser caching: added ?t=Date.now() cache-bust query param to the /api-keys fetch. Root cause: browser returned 304 (Not Modified) with stale cached response (Session 82)
• landing/console.html — Fixed plan display not updating in Account tab: renderApiKeysList() now calls loadAccountTab() after setting currentPlan from API keys (keys.length > 0 branch was missing this call) (Session 82)
• landing/console.html — Made loadAccountTab() async: when currentPlan === 'free' (still loading), it now fetches /api-keys directly before rendering, eliminating all timing-dependent "Free" display issues (Session 82)

🟢 Landing

• landing/console.html — Added refreshSidebarAccess() function. Unlocks Secure RAG sidebar items (🔒→📦 icon, docs link) for Starter+ users after plan is determined. Also centralizes SEva 📎 button control (Session 82)
• landing/seva/seva.js — Added _attachEnabled instance variable. setAttachmentEnabled() now persists state so it's correctly applied even if called before DOM is ready (Session 82)

🔵 Proxy + Landing + SEva

• proxy/index.js — Unified email resolution in /upload endpoint to use resolveUserEmail(). Now accepts Supabase JWT (Authorization: Bearer) to identify users, enabling file uploads from the Developer Console (Session 82)
• proxy/index.js — /upload plan check now queries both credits and api_keys tables, using whichever shows a higher plan. Fixes case where credits is outdated (free) but api_keys shows starter (Session 82)
• landing/seva/seva.js — Added getAuthHeaders callback option. _processFileAttach now includes auth headers in the /upload fetch (Session 82)
• landing/console.html — Added getAuthHeaders: () => getAuthHeader() to SevaWidget init. Sends Supabase JWT with file upload to pass plan check (Session 82)
• landing/console.html — Changed onAuthSuccess() to loadApiKeys().then(() => refreshSidebarAccess()). Sidebar now auto-unlocks after login without requiring Account tab visit (Session 82)
• landing/console.html — Added plan badge to topbar (topbar-plan-badge). Shows colored badge (Free/Starter/Business/Enterprise) immediately after plan is confirmed. Hidden on logout (Session 82)
• landing/console.html — Added initPlanBadge(): independent plan detection function called on login. Fetches /api-keys directly, sets currentPlan, then calls refreshSidebarAccess(). Decoupled from loadApiKeys() list display logic (Session 82)
• landing/console.html — Added SEva refreshContext() call inside refreshSidebarAccess(). Context chip now updates to show correct plan (Session 82)

🔵 Landing

• landing/console.html — Fixed all Japanese sample texts in SCENARIOS and PRESETS to use space-separated names (山田太郎 → 山田 太郎, etc.). Affects mask, detect, RAG ingest, and preset scenarios (Session 82)
• landing/console.html — Added extraTypes: ["name"] to runRequest() body for Japanese language mode. Console demos now correctly detect and mask Japanese names (Session 82)
• landing/console.html — Replaced plan gate "View Plans" link with a direct "Upgrade to [Plan]" button. Starter+ features route to Starter Stripe Checkout; Business+ features route to Business Stripe Checkout; Enterprise shows a contact link (Session 82)

🔵 Proxy + Docs

• proxy/index.js — Added requireStarterPlan() helper function. Unifies plan checking for API key auth (req.apiKey.plan) and Supabase JWT auth (both credits and api_keys tables). Returns 403 for Free plan requests. Reusable middleware for premium endpoints (Session 82)
• proxy/index.js — Applied requireStarterPlan() to /rag/ingest and /rag/resolve. Secure RAG is now restricted to Starter plan and above at the API level (Session 82)
• docs/ja/api/rag.md / docs/en/api/rag.md — Added "Starter Plan Required" warning callout at page top. Documents the 403 behavior and links to pricing page (Session 82)

🟢 Landing + SEva

• landing/seva/seva.js — Fixed file attach button label from "Business" to "Starter+" (both ja/en). File upload is available from Starter plan (Session 82)
• landing/seva/seva.js — _appendSystemNote() now returns the DOM element. _processFileAttach() removes the "Processing file..." message once the review card is displayed (Session 82)
• landing/seva/seva.js — Added AbortSignal.timeout(60000) to /upload fetch. Times out after 60s with error message instead of hanging indefinitely (Session 82)
• landing/console.html — Added rag_ingest and rag_resolve to SCENARIOS. Clicking Secure RAG sidebar items now opens a test panel inside the console instead of attempting to open external docs (Session 82)
• landing/console.html — Added RAG routing and body construction in runRequest() for rag_ingest/rag_resolve scenarios (Session 82)
• landing/console.html — Added RAG response visualization in renderPreview(): ingest shows chunk list + token count; resolve shows restored text + count (Session 82)

🟡 Landing

• landing/console.html — Extended SEva file attachment to Starter plan (📎 button now shown for Starter/Business/Enterprise) (Session 82)
• landing/seva/seva.js — Added 1 MB file size limit; shows error message in chat if exceeded (Session 82)

🟢 Landing

• landing/seva/seva.js + landing/seva/seva.css + landing/console.html — Business/Enterprise Tier file attachment in SEva chat: added 📎 button to chat input (visible for Business/Enterprise plans only). Flow: select file → proxy /upload (text extraction + PII masking) → in-chat review card (PII count, masked preview) → [Send] pushes masked text into SEva. Supported formats: PDF, Word, Excel, PowerPoint, CSV, TXT, MD, HTML, RTF (Session 82)

🔵 Landing

• landing/console.html — Fixed TOTP re-enrollment error: automatically unenroll unverified factors before calling mfa.enroll(), eliminating "Failed to get QR code" errors on retry (Session 81)
• landing/console.html — Fixed TOTP QR code rendering: switched from innerHTML template literal to createElement + img.src assignment. Root cause was double quotes inside the data URI breaking the HTML attribute (Session 81)

🟡 Landing

• landing/console.html — Account tab: plan-aware action buttons. Free → shows "Upgrade to Starter" and "Upgrade to Business" buttons (direct Stripe Checkout); Starter → shows "Upgrade to Business" button; Business/Enterprise → shows "View Plans" link. Stripe portal button hidden for Free plan users (Session 81)

🟢 Proxy

• proxy/index.js — Added POST /stripe/create-portal-session. Generates a Stripe Customer Portal URL, enabling the "Open Stripe Portal" button in the Account tab (Session 81)

🟢 Landing

• landing/console.html — Account Settings page implemented with 4 tabs: Profile / Security / Activity / Account. API Key management moved from sidebar to Security tab. Profile tab allows setting display name and company name (saved to Supabase user_metadata). Activity tab shows login history and account creation date. Account tab shows plan usage, Stripe billing portal link, and account deletion request. Topbar and org selector now show display name / company name when set (Session 80)
• landing/console.html — Two-factor authentication (TOTP) implemented: required for Business/Enterprise plans, optional banner for Starter. Login flow adds TOTP challenge as Step 3. Supabase MFA enroll/challenge/verify API integration. QR code display and manual secret key entry supported (Session 80)
• landing/api-keys.md — Removed plan-tier API call limit table; replaced with link to Plans & Feature Limits page to avoid future sync issues (Session 80)

⚪ Docs

• docs/ja/guide/limitations.md — Added new section honestly documenting the space-required limitation for Japanese name detection, including workarounds and planned improvement (Session 80)
• docs/en/guide/limitations.md — Added name detection space requirement to English limitations page, including Japanese-specific impact note (Session 80)
• docs/ja/api/rag.md — Fixed Proxy API example and test result: replaced 山田太郎 (no space) with 山田 太郎 (space) + added extraTypes: ["name"]. Test result updated to show name tokenized correctly (3/3 → 4/4) (Session 80)
• docs/en/api/rag.md — Updated Proxy API example to use Alice Smith (space) + extraTypes: ["name"]. Test result updated to include name token (Session 80)

• Support Chat (Supportchat/poc/src/server.ts) — SEva Enterprise Privacy Briefing: STEP 0 added before persona selection. SEva asks for company name, division, contact name, and contact info at the start of Enterprise consultations. Declared terms are registered as session-level custom masks and applied via extractDeclaredPII() + maskWithCustomTerms() before writing to seva_logs — company names and contact PII are never stored in plain text (Session 77)
• landing/seva/seva.js + landing/console.html — Prospect tracking: userId (Supabase UUID) and endpointsTried added to SEva context; forwarded to Railway for purchase-intent scoring (Session 76)
• landing/seva/seva.js + landing/console.html — SEva default open: panel opens automatically on console load (defaultOpen: true); users can hide via tab button (Session 76)
• landing/seva/seva.js — SalesEva: added callsUsed and callLimit to server context note, enabling usage-based upgrade nudges in SYSTEM_PROMPT (Session 76)
• landing/seva/seva.js + landing/seva/seva.css — SEva feedback button layout fix: buttons now appear BELOW the chat bubble (column layout via .seva-bub-wrap wrapper) instead of to the right (Session 75)
• landing/seva/seva.js + landing/seva/seva.css — SEva Learning Loop Phase 3: 👍/👎 feedback buttons added to bot messages. _rate() method (fire-and-forget to chatUrl/rate). JA/EN i18n support (Session 74)

• landing/console.html — OTP input: maxlength changed from 6 to 8; label updated to "確認コード（6〜8桁）" (Supabase sends 8-digit codes in some cases) (Session 73)
• landing/seva/seva.js + landing/seva/seva.css — SEva (SupportEva) Phase 1: AI technical support widget as standalone reusable module (SevaWidget class); right-side 340px slide panel, Railway chat API connection, Privacy by Design context passing, JA/EN i18n (Session 73)
• docs/en/api/seva.md + docs/ja/api/seva.md — SEva documentation: overview, Privacy by Design principles, FAQ, example questions; added to sidebar under Infrastructure & Operations (Session 73)
• landing/console.html — SEva contextFn complete: added endpointsTried (visited endpoint history, dedup, max 10), callsUsed (monthly total across all keys), callLimit (plan limit); all three are behavioral metadata only — Privacy by Design boundary maintained (Session 73)
• landing/seva/seva.js — SEva Phase 2: full PII Firewall pipeline on every message (detectAllInjections → mask → Railway chat → restore-text); attack blocking with counter, PII mask count display, graceful degradation on pipeline errors (Session 73)
• docs/en/api/seva.md + docs/ja/api/seva.md — Enriched SEva docs: full pipeline diagram (detectAllInjections → mask → Secure RAG → Claude → restoreAll), Secure RAG knowledge base architecture, real-time protection stats explanation, expanded FAQ and question examples (Session 73)
• landing/tokusho.html — Phone number updated from "pending" to 070-3630-6741 (JA/EN); removed "pending" note (Session 71)
• landing/index.html — All nav items (Products, Solutions, Developers, Resources, Pricing, Sign In) fully disabled via pointer-events:none; opacity:0.45; cursor:default; Sign In also gets onclick="return false" during patent application period (Session 71)

🔵 Infrastructure & Security (Session 71)

• 2FA enabled on all services: GitHub (Passkey+TOTP+Recovery), Cloudflare (TOTP+Backup), Supabase (App 278), Railway (App+Recovery) (Session 71)

• landing/index-v2.html — Secure RAG section removed (patent pending, not for public disclosure) (Session 67)
• landing/index-v2.html — Purchase flow fix applied: Start Starter/Business → OTP → redirect with ?plan= param → Stripe Checkout auto-launch (Session 67)
• landing/index-v2.html — Added missing auth modal HTML (was causing null classList error on Start Starter click) (Session 67)
• landing/portal.html — Added Stripe Checkout auto-launch on ?plan=starter|business URL param after OTP redirect (Session 67)

• proxy/index.js — CORS: added pii-firewall.pages.dev to allowed origins (Cloudflare Pages preview URLs use hyphen, not piifirewall.com, causing Stripe session fetch to be blocked) (Session 67)
• Purchase flow: Fixed "Start Starter/Business" → OTP → Stripe Checkout not launching; now auto-triggers checkout after OTP verification (Session 66)
• Updated @xmldom/xmldom from 0.8.11 → 0.9.10 (High: XML injection vulnerability GHSA-wh4c-j3r5-mjhp) (Session 66)
