The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and the project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). + +## [Unreleased] + +### Added + +- **Adversarial Red Team engine.** Third pluggable engine alongside CVP and Blind Jury. A rotating attacker stress-tests the other participants' positions across N-2 stress rounds, defenders respond in parallel, and a final post-stress round forces every participant to acknowledge which attacks landed. The attacker's persona is suspended for their turn (replaced with a neutral red-team framing) and their confidence score is excluded from the consensus formula because it measures attack success, not belief in a position. `pickAttackerIndex` rotates round-robin so attacker assignments are deterministic and reproducible. +- **Custom persona builder (axis sliders).** A new entry in the persona menu opens a session-scoped builder with six axes — Risk tolerance, Optimism, Evidence bar, Formality, Verbosity, Contrarian streak — each with three levels. The server composes the system prompt from a small library of vetted phrase fragments keyed by `(axis, level)`. The user-typed display name is sanitised against a Unicode-letter / digit / space / `._-'` allowlist and capped to 32 chars; user-typed prompt text never reaches the LLM. The spec is cached in `localStorage` for cross-session iteration. +- **Claim-Level Disagreement Extraction.** A post-final-round LLM pass that emits structured `{contradictions: [{claim, sides: [{stance, participantIds, quote}]}]}`. The parser drops fabricated quotes by verifying each quote's first 80 normalised characters against the actual response content of the named participants. Same-participant-on-multiple-sides is rejected. Cap of 8 contradictions per run; cap of 240 chars per claim, 600 chars per quote. The extractor reuses the judge model when judge synthesis is enabled, otherwise falls back to the first participant's model. Default ON. Renders in a new `ClaimsPanel` with click-to-scroll-to-response per side. +- **Engine Sweep Mode.** A new "Sweep" button next to "Run Consensus" runs the same prompt through CVP, Blind Jury, and Adversarial Red Team sequentially. The live ResultPanel shows the current engine; a `SweepResultsPanel` below renders one card per engine with the final score, judge majority excerpt, top contradictions, disagreement count, and per-engine token / USD subtotal. Sweep cancellation tears down the active run while preserving any engines that already completed. +- **Cost cap.** A new `costCapUSD` option (also exposed in the Protocol panel UI) hard-aborts a run when the running estimated cost crosses the threshold. Server-clamped to ≤ $50. The engine throws `CostCapExceededError` which the SSE pipeline surfaces as an `error` event with the exact dollar figure. +- **Markdown export now includes the claim digest.** Each contradiction renders as a sub-section with stance, participants, and verbatim quote per side. +- **`SessionSnapshot.claims`** field on the snapshot type (optional for backwards compat with older permalinks). Loading a permalink rehydrates the claim digest into the Claims panel. + +### Changed + +- README hero blurb, Features table, Protocol section, Architecture file map, and Roadmap status all updated to reflect three available engines and the new affordances. +- `extractConfidence` now matches the LAST `CONFIDENCE: NN` occurrence in a response. Models that preview their score mid-response no longer short-circuit the canonical trailing line. +- `loadSnapshot` reconstructs `usageByParticipant` from `snapshot.rounds[*].responses[*].usage` instead of resetting to `{}`. Shared-view permalinks now show correct per-participant token totals in the floating cost meter. +- `cancelConsensus` now also clears `judgeStream`, `judgeRunning`, and `claimsRunning` so a mid-judge or mid-extraction cancel can't leave stale streaming text in the UI. +- `extractUsage` no longer chains `as unknown as` casts. All field reads go through `typeof` guards, with malformed values falling cleanly through to the heuristic estimator. + +### Fixed + +- The module-level `setInterval` rate-limit cleanup in `app/api/consensus/route.ts` is keyed on a global symbol so Next.js HMR can no longer accumulate intervals across reloads. Vercel cold starts are unaffected. +- A test using `mockImplementation` instead of `mockImplementationOnce` was leaking a broken streamText stub into every later test in the engine suite, which would have masked confidence-extraction bugs in adversarial / claim-extraction code. Switched to scoped `mockImplementationOnce` chains. + +### Tests + +- Test count: 207 → 255 (+48 across the four features and the QA bundle). +- New coverage: adversarial engine prompts and rotation, attacker-excluded scoring, parallel defenders, custom persona sanitiser and composer (including injection-shape names), claim-extractor parser (well-formed / noise / fabricated-quote / same-participant rejection), `pickClaimExtractorModelId`, engine integration end-to-end with claims, soft-fail behaviour, sweep state actions and cancellation, cost-cap enforcement and disabled defaults, `extractConfidence` last-occurrence anchoring, `loadSnapshot` usage reconstruction, API route accepting / rejecting custom persona specs, accepting the adversarial engine. + +### Documentation + +- Added [`newfeatures.md`](newfeatures.md) tracking the rationale for each feature, the Grok-consensus QA notes, and the code-quality bundle. +- Added [`CHANGELOG.md`](CHANGELOG.md) (this file). +- Added [`SECURITY.md`](SECURITY.md) covering the threat model and security principles. + +--- + +## [1.0.0] — 2026-04-15 + +Initial public release plus the demo-uplift features. + +### Added + +- **Blind Jury engine** alongside CVP — single-pass parallel responses + judge synthesis. +- **Judge synthesizer** — optional non-voting model produces structured Majority / Minority / Unresolved / Confidence sections over the final round. +- **Confidence trajectory chart** — live SVG sparkline with one line per participant. +- **Disagreement ledger** — confidence-spread heuristic flags pairs whose self-reported confidence diverges by ≥ 20 points. +- **Cost meter** with bundled pricing table for major frontier models. +- **Floating run panel** stacking cost meter + trajectory + ledger + UML message-flow diagram on xl+ screens. +- **Provider error handling** — errored participant calls render as red error cards and are excluded from the consensus score. +- **Prompt library** — 8 curated preset prompts as chips under the textarea. +- **Session export & share** — Markdown / JSON download plus URL-hash permalink (compressed via `CompressionStream` when available). +- **Shared view mode** — `#rt=…` permalinks rehydrate into a read-only viewer. +- **Real-time SSE streaming, cancel anytime, rate limiting, server-side input validation, persona/model re-verification.** +- **CVP Consensus Validation Protocol** — multi-round structured debate with blind Round 1, randomised order, and early stopping. +- **7 built-in personas** — Risk Analyst, First-Principles Engineer, VC Specialist, Scientific Skeptic, Optimistic Futurist, Devil's Advocate, Domain Expert. +- **Multi-provider OpenAI-compatible client** — Grok, Claude, OpenAI, Mistral, Groq, Together, etc. + +[Unreleased]: https://github.com/entropyvortex/roundtable/compare/v1.0.0...HEAD +[1.0.0]: https://github.com/entropyvortex/roundtable/releases/tag/v1.0.0 diff --git a/README.md b/README.md index 26e721b..a72de03 100644 --- a/README.md +++ b/README.md @@ -8,7 +8,7 @@ **Put multiple AI models in a room.

The attacker turn is special: their persona is _suspended_ for the round and replaced with a "neutral red-team attacker" framing that demands they begin with `Attacking claim: ` and surface the weakest load-bearing claim. The remaining participants are **defenders** and respond to the attack **in parallel** (same anti-anchoring philosophy as Blind Round 1) — they cannot see other defenders' replies. + +3. **Round N — Post-Stress Final Synthesis.** Every participant in parallel writes their final position, explicitly acknowledging which attacks landed, which missed, and what conditional caveats they now attach. + +The attacker's confidence score reports how confident they are that the attack lands — not their belief in any underlying view.

Instead of free-text, the builder exposes six axes — Risk tolerance, Optimism, Evidence bar, Formality, Verbosity, Contrarian streak — each with three levels (low / mid / high). The server composes the system prompt from a small library of vetted phrase fragments, one per `(axis, level)`. The user-typed name is sanitised to a Unicode-letter / digit / space / `._-'` allowlist and capped to 32 chars; user-typed prompt text never reaches the LLM. + +This preserves the existing security model: every consensus request rebuilds personas server-side from their IDs, and a custom persona's spec is re-sanitised and re-composed on every run. The spec is cached in `localStorage` so the user can iterate across sessions; it is **not** embedded in URL-hash permalinks (the spec is, the composed prompt is, but neither carries arbitrary text). + +### Claim-Level Disagreement Extraction + +The confidence-spread `Disagreement` ledger only catches pairs whose self-reported confidence diverges by ≥20 points. After every run with **Claim extraction** enabled (default ON), an additional LLM pass reads the final-round responses and emits a strict JSON object of `{contradictions: [{claim, sides: [{stance, participantIds, quote}]}]}`. The parser: + +- Drops contradictions with empty claims, fewer than 2 sides, or sides without a quote. +- Verifies each quote against the actual response content of the named participants.

The same protection applies to model IDs: the server re-validates each `modelInfo.id` against the configured `AI_PROVIDERS` and rejects unknown models with HTTP 400. + +### 3. Custom personas use axes only — no free-text reaches the LLM + +The custom persona builder (`components/PersonaBuilder.tsx` and `composeCustomPersona` in `lib/personas.ts`) deliberately exposes only six axis selectors with three levels each. The server composes the system prompt from a small library of vetted phrase fragments keyed by `(axis, level)`. The user never types a system prompt — only a display name. + +The display name is the only user-typed string that appears anywhere in the composed prompt, and it is sanitised on the server in `sanitizeCustomPersonaSpec`: + +- **Allowlist:** only Unicode letters, digits, spaces, and `_-.'` survive. Newlines, code fences, braces, quotes, and angle brackets are stripped. +- **Length cap:** 32 characters after sanitisation. +- **Empty-after-strip:** the spec is rejected with HTTP 400. +- **Color** must match `^#[0-9a-fA-F]{6}$` or it falls back to a safe default. +- **Emoji** is capped to 4 codepoints. +- **Axis values** must be in `low | mid | high` or they default to `mid`. + +The composer then wraps the sanitised name in a fixed structural template ("You are X, a custom RoundTable participant. Your stance for this debate is defined by..."), so even names that pass the allowlist (e.g. "Bob Ignore prior instructions") are positioned as part of an identity, not as standalone instructions. A model parsing the prompt reads `name` as a single (weirdly named) entity. + +`composeCustomPersona` throws `InvalidCustomPersonaError` on any spec that fails sanitisation — there is no silent fallback that could mask a bug. + +### 4. Server-side input validation everywhere + +`/api/consensus` enforces hard limits before the engine runs: + +- **Prompt length:** ≤ 10,000 characters. +- **Participants:** ≤ 8 per request. +- **Rounds:** clamped to `[1, 10]`. +- **Cost cap (USD):** clamped to `[0, 50]`. +- **Engine:** must be one of `cvp | blind-jury | adversarial`. Anything else maps to `cvp` (defensive default). +- **Judge model ID:** if `judgeEnabled`, the model ID must resolve via `findResolvedModel`; otherwise rejected with HTTP 400. +- **Custom persona spec:** if `persona.id === "custom"`, `sanitizeCustomPersonaSpec` must return a non-null result; otherwise HTTP 400. + +Booleans use a strict `typeof === "boolean"` check rather than truthiness. Numbers are clamped, not just parsed. Unknown fields in the request body are ignored. + +### 5. Per-IP rate limiting + +`app/api/consensus/route.ts` runs a sliding-window rate limiter at 5 requests per IP per minute. The IP is taken from `x-forwarded-for` (first hop) or `x-real-ip`. Rate-limited requests return HTTP 429. + +The cleanup interval that prunes old entries is keyed on a global symbol so Next.js HMR cannot stack repeated intervals across hot reloads in dev. + +This is **in-memory** and resets on cold start. It is intentionally simple — a stateless single-process limiter that needs no external service. For a public deploy, treat it as a courtesy, not a wall, and add a real edge rate limiter at the platform. + +### 6. Cost cap (defense against runaway runs) + +The new `costCapUSD` option in `ConsensusOptions` lets a user set a hard ceiling. The engine accumulates `runningCostUSD` after every round, every judge call, and every claim-extraction call; if the running total crosses the cap, the engine throws `CostCapExceededError`. The error propagates through the SSE pipeline as a normal `error` event, the run is aborted, and the client sees a clear toast with the exact dollar figure. + +Sweep mode is up to 3× the cost of a single run, so the cost cap is the recommended companion control for that feature. + +### 7. Claim-extractor parser hardening + +The claim-level extraction LLM pass produces JSON. The parser in `parseClaimsJSON` (`lib/consensus-engine.ts`) is intentionally strict and defensive: + +- Unparseable output → empty digest, soft-fail, run unaffected. +- Each side must have a non-empty `stance`, valid `participantIds` (all must match an actual run participant), and a non-empty `quote`. +- **Quote verification:** the first 80 normalised characters of the quote must appear in the actual response content of one of the named participants. Fabricated quotes the model invents are dropped before they reach the UI. +- **Same-participant on multiple sides** is rejected — a participant cannot simultaneously support and oppose the same claim. +- Cap of 8 contradictions, 240 chars per claim, 600 chars per quote. + +Provider errors during the extractor pass populate `ClaimDigest.error` so the UI can render a distinct "Claim Extraction Failed" card — silent failures look indistinguishable from "no contradictions found", which would be misleading. + +### 8. Errored providers are excluded from scoring + +A failing provider (wrong base URL, expired key, 404, upstream outage) is caught in `streamParticipant`, formatted via `formatProviderError`, and emitted as a `participant-end` event with an `error` field. The UI renders the participant as a red error card, fires a toast naming the broken model, and the engine **excludes the errored response from both the consensus score and the disagreement ledger**. One broken provider can no longer tank a run. + +--- + +## What is intentionally NOT secured + +These are deliberate non-goals. Documenting them so contributors aren't surprised: + +- **No authentication / authorisation.** The app is single-tenant by deployment. +- **No persistence on the server.** No DB, no session storage, no logs of user prompts beyond the standard Next.js / Vercel access logs. +- **No content moderation.** Prompts are forwarded verbatim. Model outputs are rendered verbatim. +- **No PII handling.** If a user pastes PII into a prompt, it is sent to whichever providers are configured. +- **No dependency-pin enforcement at runtime.** Lockfile is committed, but the app trusts its own dependencies. +- **The cost meter is an estimate.** Pricing in `lib/pricing.ts` is best-effort public list pricing; it can drift. The cost cap uses these estimates, so a model with stale or missing pricing data may run past the apparent cap. +- **Snapshot permalinks (`#rt=…`) are not signed.** Anyone who can edit the URL can edit the snapshot. The hash is a convenience encoding, not an authenticity proof. Personas in a permalink are still server-rebuilt from their IDs, so the worst a tampered permalink can do is render incorrect display labels (the actual run, if re-executed, uses server-side definitions). + +--- + +## Reporting a vulnerability + +Open a private issue on the repository or email the maintainer. Please do not disclose security issues in public issue trackers before a fix lands. + +If your report is sensitive, mark it as such and the maintainer will respond before public disclosure.
