feat: Add initial implementation of Vulnerability Resolver Jobs

- Created project for StellaOps.Scanner.Analyzers.Native.Tests with necessary dependencies.
- Documented roles and guidelines in AGENTS.md for Scheduler module.
- Implemented IResolverJobService interface and InMemoryResolverJobService for handling resolver jobs.
- Added ResolverBacklogNotifier and ResolverBacklogService for monitoring job metrics.
- Developed API endpoints for managing resolver jobs and retrieving metrics.
- Defined models for resolver job requests and responses.
- Integrated dependency injection for resolver job services.
- Implemented ImpactIndexSnapshot for persisting impact index data.
- Introduced SignalsScoringOptions for configurable scoring weights in reachability scoring.
- Added unit tests for ReachabilityScoringService and RuntimeFactsIngestionService.
- Created dotnet-filter.sh script to handle command-line arguments for dotnet.
- Established nuget-prime project for managing package downloads.

 # Scheduler agent guide
 
 ## Mission
-Scheduler detects advisory/VEX deltas, computes impact windows, and orchestrates re-evaluations across Scanner and Policy Engine.
+Scheduler detects advisory/VEX deltas, computes impact windows, and orchestrates re-evaluations across Scanner and Policy Engine. Docs in this directory are the front-door contract for contributors.
 
-## Key docs
-- [Module README](./README.md)
-- [Architecture](./architecture.md)
-- [Implementation plan](./implementation_plan.md)
-- [Task board](./TASKS.md)
+## Working directory
+- `docs/modules/scheduler` (docs-only); code changes live under `src/Scheduler/**` but must be coordinated via sprint plans.
 
-## How to get started
-1. Open sprint file `/docs/implplan/SPRINT_*.md` and locate the stories referencing this module.
-2. Review ./TASKS.md for local follow-ups and confirm status transitions (TODO → DOING → DONE/BLOCKED).
-3. Read the architecture and README for domain context before editing code or docs.
-4. Coordinate cross-module changes in the main /AGENTS.md description and through the sprint plan.
+## Roles & owners
+- **Docs author**: curates AGENTS/TASKS/runbooks; keeps determinism/offline guidance accurate.
+- **Scheduler engineer (Worker/WebService)**: aligns implementation notes with architecture and ensures observability/runbook updates land with code.
+- **Observability/Ops**: maintains dashboards/rules, documents operational SLOs and alert contracts.
 
-## Guardrails
-- Honour the Aggregation-Only Contract where applicable (see ../../ingestion/aggregation-only-contract.md).
-- Preserve determinism: sort outputs, normalise timestamps (UTC ISO-8601), and avoid machine-specific artefacts.
-- Keep Offline Kit parity in mind—document air-gapped workflows for any new feature.
-- Update runbooks/observability assets when operational characteristics change.
 ## Required Reading
 - `docs/modules/scheduler/README.md`
 - `docs/modules/scheduler/architecture.md`
 - `docs/modules/scheduler/implementation_plan.md`
 - `docs/modules/platform/architecture-overview.md`
 
-## Working Agreement
-- 1. Update task status to `DOING`/`DONE` in both correspoding sprint file `/docs/implplan/SPRINT_*.md` and the local `TASKS.md` when you start or finish work.
-- 2. Review this charter and the Required Reading documents before coding; confirm prerequisites are met.
-- 3. Keep changes deterministic (stable ordering, timestamps, hashes) and align with offline/air-gap expectations.
-- 4. Coordinate doc updates, tests, and cross-guild communication whenever contracts or workflows change.
-- 5. Revert to `TODO` if you pause the task without shipping changes; leave notes in commit/PR descriptions for context.
+## How to work
+1. Open relevant sprint file in `docs/implplan/SPRINT_*.md` and set task status to `DOING` there and in `docs/modules/scheduler/TASKS.md` before starting.
+2. Confirm prerequisites above are read; note any missing contracts in sprint **Decisions & Risks**.
+3. Keep outputs deterministic (stable ordering, UTC ISO-8601 timestamps, sorted lists) and offline-friendly (no external fetches without mirrors).
+4. When changing behavior, update runbooks and observability assets in `./operations/`.
+5. On completion, set status to `DONE` in both the sprint file and `TASKS.md`; if paused, revert to `TODO` and add a brief note.
+
+## Guardrails
+- Honour the Aggregation-Only Contract where applicable (see `../../ingestion/aggregation-only-contract.md`).
+- No undocumented schema or API contract changes; document deltas in architecture or implementation_plan.
+- Keep Offline Kit parity—document air-gapped workflows for any new feature.
+- Prefer deterministic fixtures and avoid machine-specific artefacts in examples.
+
+## Testing & determinism expectations
+- Examples and snippets should be reproducible; pin sample timestamps to UTC and sort collections.
+- Observability examples must align with published metric names and labels; update `operations/worker-prometheus-rules.yaml` if alert semantics change.
+
+## Status mirrors
+- Sprint tracker: `/docs/implplan/SPRINT_*.md` (source of record for Delivery Tracker).
+- Local tracker: `docs/modules/scheduler/TASKS.md` (mirrors sprint status; keep in sync).

+Keep this table in sync with sprint Delivery Trackers for the Scheduler docs/process stream.
+
+| Task ID | Status | Owner(s) | Notes |
+| --- | --- | --- | --- |
+| SCHEDULER-DOCS-0001 | DONE | Docs Guild | AGENTS charter refreshed with roles/prereqs/determinism and cross-links. |

+## Status rules
+- Update both this file and the relevant `docs/implplan/SPRINT_*.md` entry whenever you change a task state.
+- Use TODO → DOING → DONE/BLOCKED. If you pause work, revert to TODO and leave a short note.
+- Document contract or runbook changes in the appropriate module docs under this directory.
