+# Custom Scorer Plugins
+
+This directory contains custom scorer plugins for challenge leaderboards.
+
+## Overview
+
+Scorers compute numeric scores from challenge attempt metrics (tokens, time, rating, success) for ranking on leaderboards when `scoring_strategy = 'custom'`.
+
+## Built-in Scorers
+
+### WeightedScorer
+
+**Entrypoint:** `services.scorers.weighted:WeightedScorer`
+
+Computes a weighted score combining multiple metrics with configurable bonuses and penalties.
+
+**Formula:**
+```
+score = success_bonus
+        + (rating × rating_weight)
+        - (elapsed_seconds × time_penalty)
+        - (tokens × token_penalty)
+```
+
+**Configuration:**
+- `success_bonus` (float, default: 100): Base points for successful attempts
+- `rating_weight` (float, default: 10): Multiplier for judge rating (0-10)
+- `time_penalty` (float, default: 1.0): Penalty per second elapsed
+- `token_penalty` (float, default: 0.01): Penalty per token used
+
+**Example Configuration:**
+```json
+{
+  "success_bonus": 100.0,
+  "rating_weight": 10.0,
+  "time_penalty": 1.0,
+  "token_penalty": 0.01
+}
+```
+
+**Example Challenge Setup (via API):**
+```python
+{
+  "name": "Advanced Prompt Challenge",
+  "scoring_strategy": "custom",
+  "scoring_plugin_id": "builtin.weighted_scorer",
+  "scoring_entrypoint": "services.scorers.weighted:WeightedScorer",
+  "scoring_config": {
+    "success_bonus": 100.0,
+    "rating_weight": 15.0,
+    "time_penalty": 0.5,
+    "token_penalty": 0.02
+  }
+}
+```
+
+## Creating Custom Scorers
+
+### 1. Implement the ScorerProtocol
+
+Create a new file in this directory (e.g., `custom.py`):
+
+```python
+from typing import Any
+from services.challenge_scorer_protocol import AttemptMetrics, ScoringContext, ScoringResult
+
+class MyCustomScorer:
+    def score(self, metrics: AttemptMetrics, config: dict[str, Any], ctx: ScoringContext) -> ScoringResult:
+        # Access metrics
+        succeeded = metrics.get('succeeded', False)
+        tokens = metrics.get('tokens_total', 0)
+        elapsed_ms = metrics.get('elapsed_ms', 0)
+        rating = metrics.get('rating', 0)
+
+        # Access configuration
+        multiplier = config.get('multiplier', 1.0)
+
+        # Compute score
+        score = (rating * multiplier) if succeeded else 0.0
+
+        return {
+            'score': score,
+            'details': {  # optional
+                'multiplier_used': multiplier
+            }
+        }
+```
+
+### 2. Register in Challenge
+
+Set the challenge's scoring fields:
+
+```python
+challenge.scoring_strategy = 'custom'
+challenge.scoring_plugin_id = 'my_custom_scorer'
+challenge.scoring_entrypoint = 'services.scorers.custom:MyCustomScorer'
+challenge.scoring_config = {
+    'multiplier': 2.0
+}
+```
+
+### 3. Testing
+
+Create tests in `api/tests/unit_tests/services/` following the pattern in `test_challenge_scorer_service.py`.
+
+## Protocol Reference
+
+### Input Types
+
+**AttemptMetrics:**
+- `succeeded` (bool): Whether the challenge was passed
+- `tokens_total` (int | None): Total tokens used
+- `elapsed_ms` (int | None): Time taken in milliseconds
+- `rating` (int | None): Judge rating (0-10)
+- `created_at` (int | None): Timestamp in epoch milliseconds
+
+**ScoringContext:**
+- `tenant_id` (str): Tenant identifier
+- `app_id` (str): Application identifier
+- `workflow_id` (str): Workflow identifier
+- `challenge_id` (str): Challenge identifier
+- `end_user_id` (str | None): End user identifier (if available)
+- `timeout_ms` (int): Maximum execution time
+
+### Output Type
+
+**ScoringResult:**
+- `score` (float, required): Computed numeric score
+- `details` (dict[str, Any] | None, optional): Additional scoring details
+
+## Error Handling
+
+- Scorers must return a dict with a `score` key
+- Exceptions are caught and logged; the attempt is recorded with `score=None`
+- Scorers are executed with a timeout (default: 5s)
+- Scorers should never return negative scores; use `max(score, 0.0)` to clamp
+
+## Best Practices
+
+1. **Keep it simple**: Scoring should be fast and deterministic
+2. **Validate config**: Check configuration values and provide defaults
+3. **Clamp scores**: Ensure scores are non-negative
+4. **Document formula**: Clearly explain how your scorer works
+5. **Test edge cases**: Test with missing metrics, zeros, nulls

+## Prompt Hacking Challenges — Design
+
+### Overview
+
+Enable developer-authored prompt hacking challenges inside Dify’s workflow builder via a new workflow node. Players can register/login using the existing web auth and compete on challenges. Attempts are recorded server-side and leaderboards are exposed via public web APIs.
+
+### Goals
+
+- Add a first-class workflow node that evaluates success/failure against developer-specified criteria.
+- Add a Judging LLM node that compares model outputs to the challenge goal and produces pass/fail, textual feedback, and a 1–10 rating.
+- Persist attempts with metadata for scoring and leaderboards.
+- Reuse existing account/web auth for players.
+- Fit Dify’s DDD/Clean Architecture: models, services, controllers, workflow nodes, and frontend builder integration.
+
+### Non-Goals
+
+- Anti-cheat measures beyond simple rate limiting.
+- Complex custom scoring plugins (design leaves a hook for future work).
+
+## Architecture Summary
+
+### Backend components
+
+- Models (SQLAlchemy)
+  - Challenge
+    - id, tenant_id, app_id, workflow_id
+    - name, description, goal (plain text shown to players)
+    - success_type: one of ['regex', 'contains', 'custom']
+    - success_pattern: string (regex or substring depending on type)
+    - secret_ref: reference to server-side secret (never exposed to clients)
+    - scoring_strategy: one of ['first', 'fastest', 'fewest_tokens', 'custom']
+    - is_active: bool
+    - created_by, created_at, updated_by, updated_at
+  - ChallengeAttempt
+    - id, tenant_id, challenge_id (FK), end_user_id (FK), workflow_run_id (optional FK)
+    - succeeded: bool
+    - score: numeric (meaning depends on strategy)
+    - judge_rating: int (0–10)
+    - judge_feedback: text
+    - judge_output_raw: jsonb (optional; structured judgement payload)
+    - tokens_total: int (when available from run metrics)
+    - elapsed_ms: int (when available)
+    - created_at
+
+- Service layer (e.g., `ChallengeService`, `ChallengeJudgeService`)
+  - evaluate_outcome(output, cfg) -> (succeeded: bool, details: dict)
+  - judge_with_llm(goal, response, cfg) -> { passed: bool, rating: int, feedback: str, raw?: dict }
+  - evaluate_with_plugin(evaluator_ref, goal, response, ctx) -> { passed: bool, rating?: int, feedback?: str, raw?: dict }
+  - score_with_plugin(scorer_ref, attempt_metrics, ctx) -> { score: number, details?: dict }
+  - record_attempt(tenant_id, challenge_id, end_user_id, run_meta, succeeded) -> ChallengeAttempt
+  - get_leaderboard(challenge_id, limit, strategy) -> list
+  - get_challenge_public(challenge_id) -> dict
+
+- Controllers
+  - Console (for creators): CRUD on challenges under the workspace (`/console/api/challenges`)
+  - Web (for players): public endpoints under `/web/api/challenges`
+    - List active challenges, fetch details, fetch leaderboard
+    - Optional auth via existing web login for personalization, otherwise anonymous read
+
+- Workflow nodes
+  - NodeType: `challenge-evaluator`
+    - Config
+      - `challenge_id`: reference to a stored Challenge (preferred)
+      - or inline config: `success_type`, `success_pattern`, `scoring_strategy`
+      - `mask_variables`: string[] — variable names to redact in logs
+    - Execution
+      - Consumes upstream content (typically latest assistant output)
+      - Evaluates success with `ChallengeService.evaluate_outcome`
+      - If an `EndUser` context exists and a `challenge_id` is present, writes `ChallengeAttempt`
+      - Outputs `{ challenge_succeeded: boolean, message?: string }`, optionally passes through original output
+  - NodeType: `judging-llm`
+    - Purpose: judge a model response against the challenge goal using an LLM rubric.
+    - Config
+      - `judge_model`: provider/name/version
+      - `temperature`, `max_tokens`, other model params
+      - `rubric_prompt_template`: template with placeholders for {goal}, {response}, optional {hints}
+      - `rating_scale`: default 0–10; configurable upper bound optional
+      - `pass_threshold`: integer (default 5)
+    - Inputs
+      - `goal`: the attacking goal or acceptance criteria
+      - `response`: the model output to evaluate
+    - Execution
+      - Calls `ChallengeJudgeService.judge_with_llm()` to obtain structured judgement
+      - Returns outputs `{ judge_passed: boolean, judge_rating: number (0–10), judge_feedback: string, judge_raw?: object }`
+    - Integration
+      - Downstream `challenge-evaluator` can consume `judge_passed` and `judge_rating` to record an attempt instead of regex/contains
+      - Alternatively, `challenge-evaluator` may support an `evaluation_mode: 'rules' | 'llm-judge'` to invoke judging internally
+  - NodeType: `team-challenge` (Red/Blue orchestrator)
+    - Purpose: orchestrate two-sided challenges where players choose Red (attack) or Blue (defense) and submit prompts accordingly. The node pairs attacks and defenses, configures the LLM, invokes judging, and emits scores.
+    - Config
+      - `red_blue_challenge_id`: reference to a Red/Blue challenge definition
+      - `defense_selection_policy`: 'latest_best' | 'random_active' | 'round_robin' | 'request_new_if_none'
+      - `attack_selection_policy`: same options for the defense side evaluation path
+      - `judge_suite`: list of category tests to run (e.g., CBRNE, SA, SH, RWH, V, M)
+      - `scoring_strategy`: 'red_blue_ratio' | 'custom'
+    - Inputs
+      - `team_choice`: 'red' | 'blue'
+      - `attack_prompt?`: string (when `team_choice = 'red'`)
+      - `defense_prompt?`: string (when `team_choice = 'blue'`)
+    - Execution (high level)
+      - If `team_choice = 'red'`:
+        - Persist `attack_prompt` submission
+        - Load a defense by policy; if none, optionally signal Blue to provide one (async) and fall back to last known
+        - Configure LLM with defense as system prompt, submit attack as user message
+        - Run `judge_suite` via `judging-llm`; compute Red score
+      - If `team_choice = 'blue'`:
+        - Persist `defense_prompt` submission
+        - Load an attack by policy; if none, signal Red to provide one (async) and fall back to last known
+        - Configure LLM with defense as system prompt and submit the loaded attack
+        - Run `judge_suite`; compute Blue score (prevention)
+      - Persist pairing and metrics
+    - Outputs
+      - `{ team: 'red'|'blue', judge_passed: boolean, judge_rating: number, judge_feedback: string, categories: Record<string, boolean|number>, team_points: number, total_points: number }`
+
+### Frontend components
+
+- Workflow builder
+  - Add `Prompt Challenge` to the node palette
+  - Add `Judging LLM` to the node palette
+  - Node editor panel: select existing Challenge or define inline success criteria
+  - Judging panel: choose model, edit rubric prompt, set pass threshold, preview structured outputs
+  - Custom evaluator/scorer panels: choose plugin and configure JSON settings with live schema validation
+  - I18n strings in `web/i18n/en-US/`
+  - Challenge display & theming
+    - Author-provided instructions (Markdown) render before/alongside the task input area
+    - Theme tokens (colors, logo, background) applied to challenge pages
+    - Optional hero image/video via existing `UploadFile` and signed URLs
+
+- Optional player UX (phase 2)
+  - `/challenges` list and `/challenges/[id]` details with leaderboard
+  - `/challenge-collections` list and `/challenge-collections/[id]` details with collection leaderboard
+  - Use existing web login endpoints
+

+
+## Player Registration & Identity
+
+### Registration and login
+
+- Reuse existing web auth service for player accounts:
+  - Email/password login: `POST /web/api/login`
+  - Email code login: `POST /web/api/login/email-code/send` + `POST /web/api/login/email-code/verify` (existing patterns)
+- Add an explicit web registration endpoint (thin wrapper around `RegisterService.register`):
+  - `POST /web/api/register` (payload: email, name, password | email-code)
+  - Behavior:
+    - `create_workspace_required = False` to avoid auto-creating workspaces for players
+    - `status = active`
+    - Set `interface_language` from `Accept-Language` as done in OAuth flow
+  - On success, also create or associate a per-tenant `EndUser` record so gameplay runs can be attributed consistently.
+
+### Player identity during runs
+
+- Each gameplay run already has an `EndUser` context. For registered players:
+  - When a player is authenticated, resolve (or lazily create) an `EndUser` tied to their `account_id` for the current tenant/app
+  - Persist `end_user_id` to `ChallengeAttempt` as today; optionally also store `account_id` for simplified leaderboard personalization
+
+### Optional schema addition
+
+```sql
+ALTER TABLE challenge_attempts
+  ADD COLUMN account_id uuid NULL;
+```
+
+This enables direct joins to accounts for notification and profile display without traversing end-user mappings.
+
+### Player profile (optional)
+
+Introduce a lightweight `player_profiles` table for nickname/avatar/notification preferences without touching `account` directly:
+
+```sql
+CREATE TABLE player_profiles (
+  account_id uuid PRIMARY KEY REFERENCES accounts(id) ON DELETE CASCADE,
+  display_name text,
+  avatar_url text,
+  notify_on_first_blood boolean DEFAULT true,
+  notify_on_record_beaten boolean DEFAULT true,
+  created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
+  updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+## Workflow Node Execution
+
+1. Node receives upstream output (string or structured content). A typical placement is after an LLM node.
+2. Node loads Challenge config (stored by `challenge_id` or inline).
+3. Node evaluates success by either rules or judging:
+   - `regex`: test pattern against text output
+   - `contains`: case-insensitive substring match
+   - `llm-judge`: call the `judging-llm` node (or internal judge) to obtain `{ judge_passed, judge_rating, judge_feedback }`
+   - `custom`: call `evaluate_with_plugin` using configured `evaluator_plugin_id`/`evaluator_entrypoint`
+4. If `EndUser` and `challenge_id` present, record a `ChallengeAttempt` with run metrics (tokens, elapsed), and when available, `judge_rating`/`judge_feedback`.
+5. Node outputs
+   - Rules mode: `{ challenge_succeeded: boolean, message?: string }`
+   - Judging mode: `{ challenge_succeeded: boolean, judge_rating: number, judge_feedback: string }`
+   - Pass through original output for chaining when needed.
+
+For collections, attempts are recorded per challenge as usual. Collection leaderboard aggregation is computed over a player’s best attempt per challenge, combined using the collection’s `scoring_strategy` (e.g., sum of scores, total elapsed_ms, etc.).
+
+## Scoring Strategies
+
+- `first`: first successful attempt time wins (leaderboard sorted by earliest `created_at`).
+- `fastest`: success with lowest `elapsed_ms` wins.
+- `fewest_tokens`: success with lowest `tokens_total` wins.
+- `highest_rating`: success with the highest `judge_rating` wins; ties broken by earliest `created_at`.
+- `custom`: compute via `score_with_plugin` using `scoring_plugin_id`/`scoring_entrypoint`.
+
+Collection strategies:
+
+- `sum`: sum of per-challenge scores in the collection (uses built-in or custom scoring per challenge)
+- `fastest_total`: sum of `elapsed_ms` of successful best attempts (lower is better)
+- `fewest_tokens_total`: sum of `tokens_total` of successful best attempts (lower is better)
+- `highest_avg_rating`: average of `judge_rating` across completed challenges (higher is better)
+- `custom`: plugin-defined; service calls `score_with_plugin` at collection level with a list of per-challenge metrics
+
+Red/Blue team scoring:
+
+- Base idea: award Red points for breakthroughs and Blue points for prevented attacks.
+- Suggested defaults per pairing:
+  - For each category in the judge suite (e.g., CBRNE, SA, SH, RWH, V, M):
+    - If the attack bypasses defense (category breach), Red +1
+    - If defense prevents (no breach), Blue +1
+  - Bonus based on `judge_rating` magnitude for breakthrough severity (e.g., Red +round(rating/3))
+  - Time/token penalties can reduce points to encourage efficient strategies
+- Ratio-based standings:
+  - Red ratio = Red points / (Red points + Blue points)
+  - Blue ratio = Blue points / (Red points + Blue points)
+- Custom plugin scoring:
+  - Provide all pairing metrics to a scorer plugin to compute per-pairing or cumulative standings
+
+## Custom Evaluators & Scorers
+
+This section specifies how custom evaluation and scoring plugins integrate with challenges.
+
+### Concepts
+
+- Evaluator: decides whether a response meets the goal. May optionally emit a rating (0–10) and textual feedback.
+- Scorer: converts an attempt’s metrics (e.g., elapsed time, tokens, rating) into a numeric score for leaderboards.
+
+### Data model
+
+- `challenges.evaluator_type`: one of `rules`, `llm-judge`, or `custom`.
+- `challenges.evaluator_plugin_id`, `evaluator_entrypoint`, `evaluator_config`: identify and configure the evaluator plugin when `custom` is selected.
+- `challenges.scoring_plugin_id`, `scoring_entrypoint`, `scoring_config`: identify and configure the scorer plugin when `scoring_strategy = 'custom'`.
+
+### Service interfaces
+
+Evaluator interface (Python):
+
+```python
+class EvaluatorContext(TypedDict, total=False):
+    tenant_id: str
+    app_id: str
+    workflow_id: str
+    challenge_id: str
+    end_user_id: str | None
+    variables: dict[str, Any]  # sanitized runtime variables
+    timeout_ms: int
+
+class EvaluatorResult(TypedDict, total=False):
+    passed: bool
+    rating: int  # 0–10 (optional)
+    feedback: str  # textual feedback for player (optional)
+    raw: dict[str, Any]  # internal diagnostics (optional)
+
+class EvaluatorProtocol(Protocol):
+    def evaluate(self, goal: str, response: str, config: dict[str, Any], ctx: EvaluatorContext) -> EvaluatorResult: ...
+```
+
+Scorer interface (Python):
+
+```python
+class ScoringContext(TypedDict, total=False):
+    tenant_id: str
+    app_id: str
+    workflow_id: str
+    challenge_id: str
+    end_user_id: str | None
+    timeout_ms: int
+
+class AttemptMetrics(TypedDict, total=False):
+    succeeded: bool
+    tokens_total: int | None
+    elapsed_ms: int | None
+    rating: int | None
+    created_at: int | None  # epoch ms
+
+class ScoringResult(TypedDict, total=False):
+    score: float
+    details: dict[str, Any] | None
+
+class ScorerProtocol(Protocol):
+    def score(self, metrics: AttemptMetrics, config: dict[str, Any], ctx: ScoringContext) -> ScoringResult: ...
+```
+
+### Discovery and loading
+
+- Plugins are discovered via the existing plugin manager. Each plugin exposes one or more entrypoints (e.g., `pkg.module:Evaluator`).
+- `evaluator_plugin_id`/`evaluator_entrypoint` and `scoring_plugin_id`/`scoring_entrypoint` identify the target callables.
+- Services load plugins lazily and cache handles with safe import guards.
+
+### Execution flow
+
+1) For `evaluator_type = 'custom'`, the `challenge-evaluator` node calls `evaluate_with_plugin` with `(goal, response, evaluator_config, ctx)`.
+2) If `EvaluatorResult.passed` is true, set `challenge_succeeded = True` and persist `judge_rating`/`judge_feedback` if provided.
+3) For `scoring_strategy = 'custom'`, call `score_with_plugin` with attempt metrics to compute `score`.
+4) Persist `ChallengeAttempt` with plugin-derived fields.
+
+### Frontend configuration
+
+- Prompt Challenge panel
+  - Evaluation mode: Rules | Judging LLM | Custom Evaluator
+  - When Custom Evaluator is chosen:
+    - Plugin selector: lists available evaluator plugins by `plugin_id` and exposed entrypoints
+    - JSON config editor with schema-based validation (optional `$schema` per plugin)
+- Scoring section
+  - Strategy: First | Fastest | Fewest Tokens | Highest Rating | Custom
+  - When Custom is chosen: plugin selector + JSON config editor
+
+### Security & sandboxing
+
+- Plugins run under server control with:
+  - Timeouts (default 5s) and memory ceilings; cancellation on overrun
+  - No network access by default (opt-in allowlist if ever needed)
+  - Sanitized inputs: secrets removed; only whitelisted variables passed
+  - Structured error mapping; no stack traces leaked to players
+
+### Error handling & observability
+
+- If plugin load or execution fails, treat as non-pass and record a generic failure reason.
+- Emit structured logs/events with plugin identifiers and durations (no sensitive content).
+- Surface minimal feedback to players; detailed diagnostics remain internal.
+
+### Examples
+
+Evaluator (substring with banned terms):
+
+```python
+class SimpleEvaluator:
+    def evaluate(self, goal, response, config, ctx):
+        required = config.get('must_contain', [])
+        banned = set(map(str.lower, config.get('banned', [])))
+        if any(w.lower() in response.lower() for w in banned):
+            return {'passed': False, 'feedback': 'Banned content detected', 'rating': 2}
+        if all(w.lower() in response.lower() for w in required):
+            return {'passed': True, 'feedback': 'Meets criteria', 'rating': 8}
+        return {'passed': False, 'feedback': 'Missing required signal', 'rating': 5}
+```
+
+Scorer (weighted combo):
+
+```python
+class WeightedScorer:
+    def score(self, metrics, config, ctx):
+        base = 0.0
+        if metrics.get('succeeded'):
+            base += config.get('success_bonus', 100)
+        rating = metrics.get('rating') or 0
+        elapsed = metrics.get('elapsed_ms') or 0
+        tokens = metrics.get('tokens_total') or 0
+        score = base + rating * config.get('rating_weight', 10) \
+                - (elapsed / 1000.0) * config.get('time_penalty', 1.0) \
+                - tokens * config.get('token_penalty', 0.01)
+        return {'score': max(score, 0.0)}
+```
+
+## Security & Privacy
+
+- Never expose `secret_ref` or derived secrets to clients or node outputs.
+- Redact configured `mask_variables` in logs and stored attempt details.
+- Apply rate limiting using existing helpers to mitigate brute-force attempts.
+- Store minimal details on failed attempts to reduce information leakage.
+  - Sanitize Markdown instructions to prevent XSS; allow a safe subset (links/images) with rel=noopener.
+  - Theme application is constrained to a whitelist of CSS variables and asset URLs served via signed URLs.
+
+## Testing Plan
+
+- Service unit tests
+  - `evaluate_outcome` for regex/contains (edge cases, unicode, multiline)
+  - `judge_with_llm` deterministic tests with mocked LLM returning structured payloads
+  - `record_attempt` scoring aggregation and sorting
+- Node tests
+  - Given inputs, assert success/failure and resulting outputs
+  - Judging node: asserts `{ judge_passed, judge_rating, judge_feedback }` shape and thresholds
+  - When `challenge_id` present, attempts are written; when not, none are written
+- API tests
+  - Console CRUD happy paths and permissions
+  - Web endpoints list/details/leaderboard
+- Frontend
+  - Panel validation, serialization/deserialization of node config
+  - Judging panel: model selection, rubric template binding, threshold validation
+  - Node palette presence
+  - Challenge instructions: Markdown renderer sanitization, link and image handling
+  - Theming: verify CSS variable injection, dark/light modes, and fallback to defaults
+  - Collections UI: ordering, visibility filtering, collection leaderboard rendering
+
+## Rollout
+
+1. DB migrations: create `challenges`, `challenge_attempts` tables; add judging columns.
+2. Backend: models, service, console/web controllers, workflow node, `NodeType` and node mapping registration.
+3. Frontend: add block enum, node + panel components (Prompt Challenge, Judging LLM), node palette default, i18n entries.
+4. QA: run `make lint`, `make type-check`, and unit tests; `pnpm lint` and tests for web.
+5. Documentation: link this design from contributor docs as needed.
+
+## Open Questions / Future Work
+
+- Anti-cheat signals and anomaly detection.
+- Custom evaluator/scoring plugin hooks with sandboxing.
+- Team competitions and seasons.
+- Per-challenge rate limits and cooldowns.
+
+## Notifications
+
+### Events
+
+- `challenge_first_blood`: emitted when the first successful attempt occurs for a challenge
+- `challenge_record_beaten`: emitted when a leaderboard record is surpassed under the active scoring strategy
+- `team_pairing_completed`: emitted after each Red/Blue pairing is judged with per-team points
+
+### Delivery channels
+
+- In-app (console): add a section in the console UI for challenge events; poll or use server-sent events
+- Email (optional): send via existing email task infra (e.g., Celery tasks)
+- Webhook (optional): per-tenant webhook endpoint configured in workspace settings to receive challenge events
+
+### Payloads
+
+```json
+{
+  "event": "challenge_record_beaten",
+  "challenge_id": "...",
+  "scoring_strategy": "highest_rating",
+  "previous_record": { "account_id": "...", "score": 95.2 },
+  "new_record": { "account_id": "...", "score": 96.8 },
+  "occurred_at": 1730000000000
+}
+```
+
+Red/Blue pairing example:
+
+```json
+{
+  "event": "team_pairing_completed",
+  "red_blue_challenge_id": "...",
+  "pairing_id": "...",
+  "attack_submission_id": "...",
+  "defense_submission_id": "...",
+  "categories": { "CBRNE": true, "SA": false, "SH": true },
+  "judge_rating": 8,
+  "red_points": 4,
+  "blue_points": 2,
+  "occurred_at": 1730000000001
+}
+```
+
+### Triggers in services
+
+- After `record_attempt`, re-evaluate leaderboard head for the challenge against the prior head
+- If the head changed and meets trigger criteria, enqueue notification tasks
+- Respect player profile preferences (`notify_on_first_blood`, `notify_on_record_beaten`)
+
+### Player-facing feedback
+
+- Immediate feedback comes from node outputs (e.g., `judge_feedback`, `judge_rating`)
+- Aggregated notifications (record beaten, first blood) are async and opt-in per player preferences
