+Here’s a compact, practical checklist you can use to scope or evaluate a real‑time collaborative coding platform with built‑in AI and version control.
+
+## Core real‑time collaboration
+- Low‑latency co‑editing: OT or CRDTs; remote cursor/selection, presence, “who’s typing,” file locks for binaries.
+- Awareness & comms: inline comments, threaded discussions, @mentions, emoji/quick reactions, audio/huddle toggle, follow‑mode (watch another’s viewport).
+- Conflict handling: optimistic updates, per‑block conflict hints, “accept mine/theirs,” and safe fallback to 3‑way merges.
+- Offline & recovery: local queueing with eventual sync; snapshot/restore; crash‑safe autosave.
+- Permissions: org/workspace/repo/file‑level RBAC; temporary “share link (view/comment/run only).”
+
+## AI assistance (first‑class, not bolt‑on)
+- Inline code completion & chat: IDE‑grade suggestions, /commands, ask‑about‑this‑selection.
+- Repo‑aware context: vector index over code, docs, issues; smart context windows; model routing per task.
+- Explain/fix/refactor: “Explain this,” “Add types,” “Make it idiomatic,” safe bulk edits with preview diff.
+- Test & doc generation: unit test stubs, property tests, coverage‑aware gaps; docstrings/READMEs/changelogs.
+- Review copilot: PR summary, risk hotspots, security lint, migration guides, “what changed & why.”
+- Prompt safety & privacy: organization policies, secrets redaction, allow/denyfile lists, “don’t train on my code” toggles, per‑region inference.
+- Telemetry‑aware guardrails: timeouts, token caps, cost visibility, reproducible AI actions (every AI change is a diff).
+
+## Deep version control integration
+- Git‑native: branches, commits, tags, rebase/merge, submodules/monorepos.
+- Live branch previews: ephemeral environments per branch/PR; review links.
+- PR workflow: draft PRs, required checks, code owners, suggested commits from AI.
+- Semantic merges: language‑aware conflict resolution; rename detection.
+- History UX: blame with in‑editor time travel, commit graph, bisect assist.
+- Hooks & policies: pre‑commit/CI hooks, signed commits, merge rules, conventional commits.
+
+## Execution environment & DevEx
+- Reproducible sandboxes: containerized runtimes, devcontainers/Nix, cached deps.
+- Secure terminals: per‑user ephemeral shells, resource quotas, egress controls.
+- Runner orchestration: queues for tests/lint/build; parallelization; artifact storage.
+- Multi‑language support: LSPs, debuggers, formatters; per‑project toolchains.
+- Secrets management: scoped env vars, secret scanners, just‑in‑time injection.
+- Performance: hot reload, remote debugging, port forwarding, logs/metrics panel.
+
+## Collaboration UX on top of code
+- Annotations: persistent comments on lines/blocks/files; “todo from comment.”
+- Tasks & issues: lightweight tasks, link to commits/lines; two‑way sync with Jira/GitHub.
+- Shared views: live diagrams/markdown/ADR docs; architecture notes beside code.
+- Education/pairs: driver/navigator mode, follow‑cursor, session recording & replay.
+
+## Security, compliance, and governance
+- Identity: SSO/SAML/OIDC, SCIM provisioning, device posture checks.
+- Access controls: least‑privilege defaults, audit logs (who saw/ran/changed what).
+- Data controls: encryption at rest/in transit; data residency; retention policies.
+- Compliance: SOC 2, ISO 27001, optional HIPAA/FERPA; vulnerability management.
+- Content safety: secret/PII detectors, DLP rules, policy‑based masking in AI context.
+
+## Observability & reliability
+- Workspace health: latency, error rates, model usage, queue backlogs, runner status.
+- Session analytics: collaboration heatmaps, flaky test tracking, MTTR on CI failures.
+- SLOs: <100 ms keystroke echo; 99.9% edit availability; <5 min cold‑start to code.
+
+## Extensibility
+- Plugin API: UI components, commands, server hooks, custom lint rules.
+- Webhooks & events: commit/PR/CI/AI‑action events; outbound to Slack, Teams, Webex.
+- Import/export: standard Git, open project format, API for metadata (comments, tasks).
+
+## Admin & cost controls
+- Usage governance: seat & compute budgets, AI spend caps, per‑team quotas.
+- Policy templates: e.g., “internal only,” “OSS mode,” “students.”
+- Backups & eDiscovery: immutable logs, legal hold, export tooling.
+
+---
+
+## Architecture sketch (at a glance)
+- Client: Web/desktop IDE → CRDT/OT engine → LSP adapters → AI command palette.
+- Collab service: Presence, awareness, doc store (CRDT), session recorder.
+- VCS service: Git RPC, diff/merge, PR service, commit graph, policy engine.
+- AI service: context builder (code+docs+history), prompt router, cost/guardrails, action logger.
+- Execution: Ephemeral containers/runners, cache, artifact store, secrets broker.
+- Control plane: AuthZ/RBAC, org/project configs, audit/event bus.
+- Data plane: Object store (blobs), index store (vectors), telemetry pipeline.

+
+## MVP vs. “delight” cut
+
+### MVP
+- Real‑time co‑editing with presence
+- Git basics (branch/commit/PR) + CI trigger
+- Inline AI: chat, explain, small fixes
+- Comments/mentions
+- Ephemeral dev envs with logs
+
+### Delighters
+- Repo‑aware AI with semantic search
+- Live PR previews and semantic merges
+- Session replay, pair‑mode, review copilot
+- Guardrailed AI with redaction and regionality
+- Admin cost policies + insights
+
+---
+
+## Practical acceptance criteria (examples)
+- Typing echo: p95 ≤ 100 ms across continents.
+- Merge conflicts: 90% resolved without leaving editor.
+- AI changes: 100% produce preview diffs with one‑click revert.
+- Secrets: 0 secrets leave org boundary in AI prompts (validated by scanners).
+- PR turnaround: median review time ↓ 30% after enablement.
+
+If you want, I can turn this into a RFP checklist or a roadmap with milestones and owner roles.
