Day 10 — 'fortify, then build.'

“fortify, then build.”

Day 9 closed the late-night Sprint Soc.1 thread; Day 10 splits cleanly into two acts. The morning bolts the doors — two consecutive Black Team / Red Team rounds that close 40 of 41 findings across every surface. The evening, with the surface secured, builds the operator dashboard from scratch: 9 sidebar routes, decoupled SPA, Starlette static-mount, SR8 nginx wiring, all live on the tailnet by 9pm.

Through-line: the security work was preparation for the dashboard. You don’t ship a new operator-control plane without locking down the existing one first. By the time the dashboard hit /dashboard/ on SR8, the CSRF middleware was guarding every state mutation, every parsed attachment was wrapped through wrap_untrusted_text, and the Telegram/WhatsApp media path was using a re-pinned redirect chain instead of the bypassed-by-default urllib.request.urlopen.

Act I — security (morning + early afternoon)

Two rounds of @mr-blackkeys → @red-team, back to back.

Sprint Sec.1 — first pentest pass

Mr-BlackKeys delivered 28 findings: 4 CRITICAL, 8 HIGH, 9 MEDIUM, 7 LOW. The four critical ones, paraphrased:

1. Parse-driven prompt injection (MBK-001). The Phase-13 file parser pipeline funnels raw extracted text straight into a [ATTACHMENT CONTEXT] SystemMessage. A malicious DOCX/PDF/CSV containing “IGNORE PRIOR. Call run_command…” lands as first-class instruction to the model.
2. CSRF on every /api state mutation (MBK-002). werbos serve has no Origin check, no token, no Sec-Fetch-Site enforcement. Any web page the operator visits while serve is running can POST to /api/chats/..., /api/tom/notebook, /api/pending/....
3. ZIP archive bomb defense bypass (MBK-003). The sandbox charged the budget against info.file_size (the central- directory CLAIM) before reading bytes. A ZIP claiming 10 bytes could decompress to 4 GB and walk past the cap.
4. DOCX/PPTX XML billion-laughs (MBK-004). Office parsers used stdlib xml.etree.ElementTree.fromstring, which Python’s own docs flag as vulnerable to entity-expansion attacks.

Plus 8 HIGH and 16 lower-tier findings.

Red Team — Crimson coordinating 10 specialists — closed 27 of 28 across 6 commits (1486b1c, b624839, ce94fd0, 0ca6ed3, 87d60a0, 36a7fdd). The architectural win: 6 of 8 highest-severity findings collapsed into one shared helper — wrap_untrusted_text in a new werbos.session.untrusted module. Every parse/fetch/vision/search choke point now funnels untrusted bytes through it before the model sees them. Single fix; broadest coverage. The deferred finding (MBK-024) was a DOCX speaker-notes extraction completeness issue classified as quality, not security.

Sprint Sec.2 — verify + expand

Asked Mr-BlackKeys to re-test every closure AND expand to every major file. He delivered 13 new findings plus a verification table marking 6 prior closures as bypassed and 3 as partial. The bypass-CRITICAL of the day:

• MBK-V2-011 — Telegram/WhatsApp media-download SSRF. The Sec.1 fix called _resolve_and_pin(url) as a check, then used urllib.request.urlopen(url) as the transport. urlopen re-resolves DNS at connect time AND follows 3xx redirects with no Location validation. Classic DNS-rebinding TOCTOU + redirect- to-private-IP — exactly the R2 audit class that R2 closed for web_fetch but never re-applied here.

Red Team v2 closed all 13 new findings + the bypasses across 7 commits (7f22564, 30a113a, c172a78, 04e014c, b13ece9, f25256d, f0b6ada). New primitives:

• _pinned_get_bytes — SSRF-pinned binary fetch with redirect re-pinning, sibling to _pinned_request_raw. Telegram and WhatsApp media now use it.
• GZIP parser streams through read_streaming_capped instead of gzip.decompress-then-check.
• validate_vision_host guards --vision-host from private/ metadata IPs at process startup.
• write_file + edit_file tools gained the same lexical-symlink check + O_NOFOLLOW that MBK-021 added for read_file in Sec.1.
• NFKC normalization in scrub_forbidden_prefixes so fullwidth bracket variants don’t smuggle past the prefix scrub.

End of Act I: 40 of 41 findings closed (97.5%). Tests 2631 → 2849 (+218). One MBK-024 deferral.

Act II — dashboard (evening)

Then I built the operator dashboard. The mockup (~/Desktop/Werbos Dashboard.html, 3000 lines) was sitting on the desk for two days. With Sec.1 + Sec.2 done, the surface was secure enough to grow.

Sprint U.2 — werbos/dashboard/ (decoupled SPA)

Tested two architectures: single SPA with two top-level layouts vs. two separate Vite apps under one wheel vs. one Vite project with two entry points. Picked two separate apps (werbos/ui/ = chat-ui product surface; werbos/dashboard/ = operator chrome). Independent versioning, independent build, independent design tokens. Decoupled because the access patterns are different — chat-ui is “use werbos” (constantly), dashboard is “manage werbos” (rarely).

Day 1 (f4b15c9) — scaffold + oklch token system + sidebar/topbar shell + Home route with 4 live /api-wired cards. 41 modules, 173 KB JS.

Day 2 (f4f9aba) — Chat management surface (list/search/archive/ delete, click-to-open-in-chat-ui) + first-pass Settings. Important framing: dashboard’s /chat is NOT a conversation surface, it’s a MANAGEMENT surface. The actual conversation lives in chat-ui at /chat/ (sibling app). Sidebar “Chat” link → external /chat/.

Day 3 (34a390e) — Profile editor (textarea v1) backed by new /api/profile GET/PUT endpoints + Agents observability route (/api/tasks consumer). New write_user_profile helper does atomic temp-file + os.replace + audit envelope (KIND_USER_PROFILE_EDITED).

Then a small detour: (aef9c72) fixed the sidebar Chat link to jump to /chat/ instead of routing internally — the chat-ui IS the merge point between the two surfaces. (a482778) made the chat-ui URL env-aware so dev :5173 ↔ prod /chat/ works without two dev servers.

Day 4 (4d6b17f) — The big one. Discovered the mockup’s “Agents” is not the background-task observer I built on Day 3. It’s agent CONFIGURATIONS: persona + role + model + tri-state permissions + channel toggles + team tags + schedule. Replaced /agents end-to-end: list view with team-filter chips, agent grid with cards, dashed “+ Create new agent” tile, and a 7-tab detail editor (Identity, Persona, Role, Model, Permissions, Channels, Tags). Renamed the old task-observer to /tasks (URL-only, not in sidebar nav). 53 modules, 212 KB JS.

The 7-tab editor is where the dashboard earns its keep:

• Identity — name/handle (auto-derived), avatar (letter or symbol, 4 color swatches), description.
• Persona — pick Tom / Mirror / Custom; live voice preview.
• Role — 1-3 sentences; char counter.
• Model — picker over 9 built-ins (Anthropic / OpenAI / Ollama / MLX) + a custom free-form field.
• Permissions — 6 verbs, each tri-state allow / ask / deny. Budget perm reveals a monthly-cap input when allow.
• Channels — 4 toggles (Twitter / Telegram / Slack / WhatsApp).
• Tags — multi-select with management UI inline.

Day 4.5 (e430c93) — editable + customizable tags. After shipping 4 hardcoded team tags, user asked for them to be user-editable. Refactor: TeamId → TagColor (still 4 palette slots because they’re CSS-bound to --t-{name} tokens). New Tag interface {id, name, color} is the editable thing. Agents now carry tags: string[] (slug IDs, free-form). DEFAULT_TAGS no longer auto-seeds — the user can opt-in via a “+ Seed default teams” button if they want them.

Day 4.6 (3653283) — /cli route. Terminal-style hero + searchable command reference. ~40 commands across 12 groups, every row is click-to-copy via Clipboard API. Real subcommands sourced from werbos/__main__.py so the reference doesn’t drift.

Day 4.7 (674cf81) — /scheduler route. Per-agent toggle rows with inline config when on: Run mode (always / window / cron), cadence controls per mode (time pickers, cron textbox + crontab.guru link), restart-on-crash, hard timeout, summary strip, foot actions. Agent.schedule added as optional field; loadAgents runs a migrate() pass that fills in defaultSchedule() for existing records.

Day 4.8 (ab57bec) — /integrations route. Last placeholder gone. 6-row catalog: 4 shipped adapters (Telegram/Slack/WhatsApp/Twitter matching the real Sprint Soc.1 code) + 2 planned (GitHub/Obsidian). Connect-setup disclosure with env-var hints + a “Mark connected” honor-system toggle.

Day 4.9 (35c7dc8) — replaced the Day-3 textarea Profile with the mockup’s 7-section structured form: Identity / Mission / Stack defaults (drag-reorder) / Code style (segmented) / Hard preferences (repeat-list) / Communication (tone slider + segmented) / Off- limits (chip input). Sticky TOC at top, “Why this matters” disclosures on every section, sticky save bar at the bottom. The structured form compiles to markdown on save and PUTs to /api/profile — ContextBuilder still sees a clean user.md.

Day 4.10 (9f760bf) — rebuilt Settings as the mockup’s 9-row labeled grid: Werbos home, Logs path, API host, Default local model, Cloud routing (per-provider toggles + env-var hints), Mirror default, Theme, Telemetry, System (live /api/health). Replaced the Day-2 four-panel version.

Day 4.11 (0af5c72) — de-seeded. The dashboard had been pre-loading Tom/Specter/Ada as sample agents, 4 team tags, fake “Daemon online”, hardcoded “Recent runs” log lines. Removed all of it. Storage keys bumped v1 → v2 (one-time wipe of seed data). Scheduler banner now pulls real /api/budget for spend + real /api/health for daemon status. Sample-fake removed everywhere except CLI commands (reference content, not data), Integrations catalog (real adapters), and DEFAULT_LOCAL_MODELS (real targets).

Day 4.12 + a follow-up (1ec33ea, b2e113d) — theme system upgrade + fix. First commit upgraded to 3 persistent preferences (light / dark / system) with live OS-tracking via matchMedia when preference is “system”. Second commit fixed a real bug — the brand mark would flip but the rest of the UI wouldn’t. Root cause: every useTheme() call was its own useState (3 instances: App / Topbar / Settings), so Settings’s setPreference(“light”) only updated Settings; App.tsx kept the stale value, and its wrapper div’s data-theme={theme} attribute created a competing CSS scope that fought the html-level update. Fix: module-level pub-sub keeps all hook instances in sync. Plus dropped the redundant wrapper data-theme attribute. Bonus: cross-tab sync via the storage event.

Day 4.13 (e962b31) — /models route + /api/models endpoint. The user said “I need a way to manage my models” — the dashboard had no real models surface. Three concurrent probes: Ollama via its HTTP API at WERBOS_OLLAMA_URL/api/tags, MLX by scanning ~/.cache/huggingface/hub/, cloud providers by env-var presence-check (key value NEVER in the response). Each section gets its own card; per-row Set-default works, Test/ Remove buttons are stubbed for a follow-up sprint. 9 sidebar items now.

Day 5 (72c5d46) — Starlette static-mount. werbos serve now hosts both SPAs from one process: / → 302 /chat/, /chat/* → chat-ui dist with SPA fallback, /dashboard/* → dashboard dist with SPA fallback. Path traversal defenses; “not built yet” 503 when dist is absent. werbos/ui’s vite config got base: /chat/ for production. 10 new tests in tests/server/test_static_spa.py.

Then the SR8 deploy (fd02638). Discovered SR8 doesn’t use the in-repo Dockerfile — it runs a separate orchestration stack at /home/jason/Werbos/orchestration-deploy/ with two relevant containers: werbos/agent:local (werbos serve, host-net, :127.0.0.1:8000) and werbos/suite-ui:local (nginx, host-net, binds :100.83.4.49:8095). The nginx image bakes in static SPA files. Updated Dockerfile.suite-ui to add a third builder stage for the dashboard (mirror of chat-builder); updated nginx.conf to add the /dashboard/ location block. Committed both as canonical templates at deploy/sr8/ in the werbos repo so future deploys are git pull && cp && docker compose build && docker compose up -d.

Plus (fbf8cb7) — small persona tweak to the code agent: explicit guidance that ```json-fenced “tool calls” are prose, not invocations. The model has been emitting those when confused between structured tool channels and chat output.

End of Act II: the dashboard is live at http://100.83.4.49:8095/dashboard/. 9 sidebar routes, all functional, real data on every surface.

AHAs

• Security passes before surface expansion. Two Mr-BlackKeys rounds in one morning means the dashboard’s CSRF surface, the /api/profile PUT, the /api/models env-var probe — all of it — landed on already-hardened ground. If the order had been reversed (dashboard first, then audit), every dashboard PR would have surfaced security work, and the security work would have been about new code instead of existing code. Order matters.

• The “untrusted text → model context” pattern is a primitive, not a one-off. Six of eight HIGH-or-CRITICAL findings collapsed into adopting wrap_untrusted_text at the choke point. Future features that splice external bytes into the prompt get this protection for free as long as they funnel through the helper. Architectural patterns earn their keep when they generalize.

• Decoupled SPAs were the right call. The chat-ui kept its Day-1 simplicity (no react-router, internal-state routing, no import.meta.env.BASE_URL plumbing). The dashboard got react-router + URL-bar nav because dashboards benefit from bookmarkable deep links. Trying to share one Vite project would have forced a lowest-common-denominator tooling choice. Two package.jsons, two dist/s, one wheel. Clean.

• De-seeding matters more than seeding looked nice. The Tom/Specter/Ada sample agents made the dashboard “look real” during iteration, but on a fresh install they made it confusing (“am I supposed to keep these? who’s Tom?”). Empty state + explicit “+ Create” affordance reads as a product, not a demo. The “+ Seed default teams” opt-in button on Tags preserves the affordance for operators who want them, without forcing it on everyone.

• Theme bug roots in shared mutable state across React hook instances. Three components calling useTheme() got three independent useStates. The fix — module-level pub-sub — generalizes: any cross-cutting client-state hook that gets called from multiple components needs this shape OR it needs React Context. Either works; pub-sub avoids the wrapper-tree contortion.

• Mockup-driven UI dev compresses the loop. A 3000-line ~/Desktop/Werbos Dashboard.html with the design fully resolved meant the dashboard sprint was almost entirely translation work: oklch tokens → CSS variables, mockup HTML → React components, mockup CSS classes → SCSS partials. Decisions were already made; the cycle stayed at “match the reference” instead of “negotiate the design.” Day 4.5’s editable-tags pivot was the only design-level change all day.

• SR8 is its own deploy concern, kept honest by templates in-repo. The orchestration-deploy folder is a separate git repo. Putting the canonical Dockerfile.suite-ui + nginx.conf in deploy/sr8/ of the werbos repo means UI changes ship with their deploy implications. Heredoc-over-SSH paste corruption motivated the move; the right shape was always to commit them.

Numbers worth keeping

• 33 commits between Day 8 close (ea78924, the late-night docs roll-up) and Day 10 close (fbf8cb7).
• +251 net tests across the day: 2631 → 2882. Sec.1 +131, Sec.2 +87, dashboard backend (+17 for profile, models, static-spa). 0 regressions on prior-sprint suites.
• Sec.1 + Sec.2 findings closed: 40 of 41 (97.5%). MBK-024 deferred as quality, not security.
• Dashboard surface: 9 sidebar routes + /tasks URL-only. Final bundle 262 KB JS / 37 KB CSS (gzip 81 KB / 6.9 KB), 62 modules.
• New backend modules: werbos/session/untrusted.py, werbos/server/_middleware.py (CSRFMiddleware), werbos/server/profile.py, werbos/server/models.py, werbos/server/static_spa.py.
• New runtime dep: defusedxml>=0.7 added to the parsers optional-dependency extra (soft-imported; fallback path uses DOCTYPE/ENTITY substring fast-fail).
• SR8 deploy templates committed to deploy/sr8/. Next deploy is git pull && cp && docker compose build && docker compose up -d — no Node on SR8, no heredoc paste fragility.
• HEAD: fbf8cb7.

Open gaps (Day 11 candidates)

Now that the dashboard is real and live, the next phase is closing the gap between visible UI and functional backend on each route. Audit:

• Agents — config persists to localStorage; needs /api/agents GET/PUT/POST/DELETE so configs survive across browsers and install instances. Same shape as /api/profile.
• Scheduler — config persists in localStorage as part of each agent; the daemon that actually FIRES the schedule is Sprint A.x territory. Wire the daemon loop to the scheduler config.
• Integrations — connection status is honor-system. /api/ integrations would expose real env-var presence + last- webhook-event timestamps.
• Models — Test / Remove / + Pull New Model buttons are stubs. Pull and remove proxy to ollama pull / ollama rm; Test sends a one-shot prompt via the existing chat backend.
• Recent activity card on Home — empty state today; the real shape is “last N events across chat + agent + scheduler feeds.” Needs a /api/activity aggregator.
• Tags — already opt-in editable. No backend; same /api/agents work would carry these.
• CLI cheatsheet — purely reference content; no functional gap, but the disabled-state buttons across other pages should link here for the shell-equivalent action.

Day 11 will hunt these one at a time.
