+# Agents, Skills, and Subagents
+
+## Purpose
+
+Define repository-canonical rules for agent execution, skill usage, and subagent delegation.
+
+## Execution defaults
+
+- Prefer repository facts first (`code`, `docs`, `CI`, `issues`, `PRs`, `history`).
+- Use skills when relevant, especially for workflow, dependency upgrades, reviews, and verification discipline.
+- Use subagents for independent analysis or implementation streams.
+
+## Minimum delegation baseline
+
+- If files are changed, execute at least one subagent call for analysis, implementation, or review.
+- For multi-step work, use at least two subagent calls where practical (e.g., investigation + domain expert validation).
+
+## Required process controls
+
+- Run `pr_continuity` when preparing PR actions.
+- Do not claim completion without running verification commands in the current state.
+- Preserve branch protection and required check baselines; do not weaken governance/security controls.
+
+## Evidence placement
+
+Prefer evidence in durable artifacts:
+
+- commits
+- PR descriptions/comments
+- workflow runs
+- repository documentation updates
+
+## Related docs

+# CodeRabbit Review Commands (BandScope)
+
+## Purpose
+
+Document the repository-standard CodeRabbit command usage for PR review flow.
+
+## Common commands
+
+- Request review: `@coderabbitai review`
+- Resume paused review: `@coderabbitai resume`
+- Pause review: `@coderabbitai pause`
+
+## Usage policy
+
+- Use one explicit review request when a PR needs AI review and no run is present.
+- Address actionable comments with code/document updates or explicit technical rationale.
+- Do not dismiss review findings without explicit maintainer/user direction.
+
+## Synchronization rule
+
+When CodeRabbit provides walkthrough/summary content that materially changes task understanding, sync key accepted decisions into PR description or linked canonical docs.

+# BandScope Acceptance Criteria
+
+## Purpose
+
+This document defines repository-wide completion criteria for implementation, verification, PR handling, and operational readiness.
+
+## Definition of done
+
+A task is complete only when all of the following are true:
+
+1. **Code correctness**: changes implement the intended behavior and include tests for regression-sensitive paths.
+2. **Verification**: local verification commands pass for touched surfaces.
+3. **Security and supply chain**: required security checks and dependency controls are preserved.
+4. **PR continuity**: changes are attached to a canonical PR path (existing or newly created).
+5. **Review handling**: actionable review findings are addressed with code or explicit rationale.
+6. **Merge readiness**: required checks are green and branch is mergeable.
+7. **Post-merge readiness**: when runtime/deploy is in scope, deployment evidence is present and validated.
+
+## Required local verification baseline
+
+Run the narrowest passing set that covers touched areas, and do not claim success without fresh output.
+
+- `npm run lint`
+- `npm run typecheck`
+- `npm run test`
+- `npm audit --workspaces --audit-level=high`
+
+When CI/workflow files, supply-chain controls, or release/security docs are changed, also run:
+
+- `python3 scripts/checks/verify_supply_chain.py`
+- `python3 scripts/checks/security_gates.py`
+
+When runtime-wide confidence is needed, run:
+
+- `./scripts/harness/quickcheck.sh`
+
+## Security notes requirement
+
+Changes touching files, URLs, subprocesses, IPC, WebView, updates, model downloads, cache/export behavior, or workflow security controls must include `Security Notes` in the relevant PR/plan/documentation.
+
+## CI acceptance baseline
+
+For protected branches, intended checks are documented in `docs/security/github-required-checks.md`. Work should not reduce or bypass these checks.
+
+## Evidence policy
+
+Completion claims must be backed by command output and/or GitHub run evidence from the current change set.

+# Harness Engineering Guide
+
+## Purpose
+
+Capture repository-local harness and verification behavior used for engineering acceptance.
+
+## Primary local entrypoint
+
+- `./scripts/harness/quickcheck.sh`
+
+Quickcheck aggregates lint/type/test/build and repository policy checks intended to mirror CI baseline safety.
+
+## Core verification commands
+
+- Lint and policy checks: `npm run lint`
+- Type checks: `npm run typecheck`
+- Tests: `npm run test`
+- Workspace vulnerability gate: `npm audit --workspaces --audit-level=high`
+
+## Supply-chain and workflow policy checks
+
+- `python3 scripts/checks/verify_supply_chain.py`
+- `python3 scripts/checks/security_gates.py`
+- `python3 scripts/checks/verify_github_bootstrap_policy.py`

+## Python analysis engine notes

+- Dependency sync: `uv sync --project services/analysis-engine --group dev`
+- Tests: `uv run --project services/analysis-engine pytest --cov=src/bandscope_analysis --cov-report=term-missing --cov-fail-under=100`
+
+## CI parity expectation
+
+Local verification should be chosen to match touched areas and must not undercut protected-branch required checks documented in `docs/security/github-required-checks.md`.

+# Deploy and Runtime Verification Runbook
+
+## Purpose
+
+Define repository-level deployment and runtime verification expectations.
+
+## Current model
+
+BandScope currently relies on GitHub Actions CI/release workflows as deploy-quality evidence for desktop artifacts and supply-chain outputs.
+
+## Required release/security evidence
+
+- Successful required checks on PR/branch (`docs/security/github-required-checks.md`)
+- SBOM artifact generation (`.github/workflows/sbom.yml`)
+- Release preflight completion (`.github/workflows/release.yml`)
+- Cross-platform build baseline completion (`.github/workflows/build-baseline.yml`)
+
+## Runtime verification baseline
+
+When runtime behavior is touched, verify:
+
+1. local app/engine tests covering the changed path pass
+2. no new high vulnerabilities are introduced (`npm audit --workspaces --audit-level=high`)
+3. policy checks for supply chain/security gates pass
+
+## Incident handling note
+
+If required workflows fail due to repository-controlled code/configuration, treat as `FAILED` and remediate in code. Use `BLOCKED` only for external permission/platform limitations.

+# API Security Checklist
+
+## Purpose
+
+Baseline checklist for tasks that introduce or modify HTTP/GraphQL/API-like surfaces.
+
+## Checklist
+
+- Validate all untrusted inputs with strict schema checks.
+- Enforce explicit allowlists for origins, hosts, and IPC channels.
+- Keep local backend access constrained to safe local channels (`127.0.0.1` or typed IPC) as applicable.
+- Apply least privilege for tokens, workflow permissions, and secrets usage.
+- Prevent command injection by avoiding shell interpolation for subprocess invocation.
+- Ensure logs and telemetry avoid leaking credentials and sensitive user data.
+- Add regression tests for rejected malformed inputs and unsafe boundary crossings.
+
+## BandScope-specific notes
+
+- File paths, URLs, metadata, model artifacts, and project formats are always untrusted.
+- Security-sensitive defaults must fail closed when validation cannot establish trust.

+## Vulnerability exception handling
+
+Exceptions are allowed only when no patched version exists and the advisory is non-exploitable for this repository context.

+- every exception must reference the exact advisory ID and reason
+- every exception must document scope, exposure, and compensating controls
+- exceptions must be encoded in repo-controlled workflow/config (not ad-hoc local commands)

The CI `security-audit` workflow applies a targeted ignore for this advisory only.

+# One-Day Delivery Plan (Canonical)
+
+## Purpose
+
+Define the execution order used to close one canonical task end-to-end in this repository.
+
+## Delivery sequence
+
+1. Re-check current git/PR/issue/CI state.
+2. Select one canonical highest-priority task based on user impact, security risk, failing gates, and merge dependency.
+3. Implement minimal root-cause fix and required tests/docs.
+4. Run local verification for touched surfaces.
+5. Commit and push on a dedicated branch.
+6. Attach to canonical PR continuity path (reuse or create PR).
+7. Resolve actionable reviews (including CodeRabbit findings).
+8. Re-verify required checks and mergeability.
+9. Enable auto-merge when policy gates are satisfied.
+10. After merge, verify downstream state (issues, follow-up PRs, deployment/runtime evidence when applicable).
+
+## Prioritization rule
+
+When multiple candidates compete, process in this order:
+
+1. Security vulnerabilities and trust-boundary defects
+2. Production breakage or deploy-blocking failures
+3. Failing required CI/E2E gates
+4. User-facing functional regressions
+5. Non-blocking enhancement backlog
+
+## PR continuity rule
+
+- Prefer updating an existing relevant PR over creating duplicates.
+- Use `pr_continuity` to identify canonical PR and duplicates.
+- Keep changes small and directly tied to the selected canonical task.
+
+## Completion policy
+
+A task is not complete on docs/plans alone; it is complete only when code, verification, and PR/CI state all reflect closure.

+# PR Continuity Policy
+
+## Purpose
+
+Ensure each change lands through a canonical PR path without duplicate or orphaned work.
+
+## Canonical PR selection
+
+1. Prefer PR whose head branch matches current working branch.
+2. If none, choose the most directly related open PR by changed files and gate impact.
+3. If multiple candidates remain, prioritize the PR blocking required checks or security posture.
+
+## Operational steps
+
+- Run `pr_continuity` before opening or updating PRs.
+- Reuse existing PR when appropriate; avoid duplicate PRs for the same fix.
+- If no suitable PR exists, create one focused PR and link relevant issue(s).
+
+## Review and gate handling
+
+- Address actionable review comments in follow-up commits.
+- Re-run or wait for required checks.
+- Enable auto-merge only when mergeable and required checks are satisfied.
+
+## State re-check rule
+
+Because PR/CI status is dynamic, re-check open PR state before every major transition:
+
+- before commit/push finalization
+- before PR creation/update
+- before merge/auto-merge actions
