Proposal System

Users can propose changes to every layer of the framework. Proposals follow a consistent two-scope model: changes take effect locally immediately, and can optionally be proposed upstream to the core framework where they go through governance.

What Can Be Proposed

Layer	What	Local (immediate)	Upstream (governance)
1. Sources	New intelligence source	Add to `security/intel/sources-local.yaml`	PR to `intel/sources.yaml`
1. Sources	New source tier	Add tier to local sources	PR to create new tier in core catalog
1. Sources	Re-score existing source	Override score in local config	PR to update score in core catalog
1. Sources	Flag stale source	Local note	PR to downgrade/remove in core catalog
1. Agents	New auditor domain	Add agent to project `.claude/agents/`	PR to `agents/focused/`
1. Agents	Update agent checklist	Modify local copy	PR to agent `.md` file
2. Governance	Board membership	N/A (core only)	GitHub Issue + team change
3. Vectors	New attack vector	Add to `security/vectors/`	PR to `vectors/community/`
3. Rules	New semgrep rule	Add to project `.semgrep/`	PR to `semgrep/`
3. Standards	New standards mapping	Add to local `standards/`	PR to `standards/`
4. Skills	New integration skill	Add to project `.claude/skills/`	PR to `skills/`

Local-First Source Management

Users can add, score, and manage sources immediately for their own project without waiting for governance approval.

security/intel/sources-local.yaml:

version: "1.0"
last_updated: "2026-03-21"

sources:
  # Internal source (project-specific, not proposable)
  - id: local-internal-pentest-reports
    name: "Internal Penetration Test Reports"
    url: "https://wiki.internal/security/pentest"
    type: page
    domains: [all]
    why: "Our internal red team tests Canton deployments quarterly"
    score:
      recency: 5
      community: 1
      depth: 5
      acceptance: 2
      authority: 4
      composite: 3.55

  # Public source flagged for upstream proposal
  - id: local-canton-defi-tracker
    name: "Canton DeFi Security Tracker"
    url: "https://example.com/canton-security"
    type: page
    domains: [authorization, state]
    why: "New tracker focused on Canton Network exploits"
    score:
      recency: 5
      community: 3
      depth: 4
      acceptance: 3
      authority: 3
      composite: 3.70
    propose_upstream: true
    proposed_tier: 4

  # Score override for a core source
  - id: override:quantstamp-audits
    score_override:
      depth: 5
      recency: 3

How agents merge both catalogs:

Load core intel/sources.yaml (from framework)
Load local security/intel/sources-local.yaml (from project)
Merge: local sources added, score overrides applied
Sort by composite score, sweep in order

Proposing Sources and Tiers Upstream

/bastion:propose --sources reads sources-local.yaml for entries with propose_upstream: true, validates the source is reachable and produces relevant content, and submits a GitHub PR.

New tier proposals include a tier definition with justification:

- id: proposed-tier-8-custody-security
  tier: 8
  tier_name: "Digital Asset Custodian Security"
  tier_description: "Security sources specific to digital asset custody"
  sources:
    - id: custody-security-alliance
      name: "Custody Security Alliance Reports"
      url: "https://example.com/custody-security"
      type: page
      domains: [authorization, state]
      score:
        recency: 4
        community: 3
        depth: 4
        acceptance: 3
        authority: 3
        composite: 3.50

Vector Proposal Flow

Zero-Friction Submission

The user's only job is to say "yes." Everything else is automated. The goal is to make sharing back easier than not sharing.

Makefile targets:

bastion-propose:          ## Review and submit all pending proposals (interactive)
bastion-propose-vector:   ## Submit a specific vector (usage: make bastion-propose-vector ID=AV-048)
bastion-propose-sources:  ## Submit all flagged local sources
bastion-propose-pending:  ## Submit everything in the pending queue
bastion-propose-dry-run:  ## Preview without creating PRs
bastion-status:           ## Show pending proposals, sync status, contribution stats

The most common flow: make bastion-propose-pending

Auto-generated PR example:

Bastion Proposal: Canton Topology Delegation Bypass

Type: Vector | Domain: authorization | Severity: HIGH | CWE: CWE-285

Description: Canton topology delegation transactions can bypass party vetting when a malicious participant submits a delegation with a forged namespace.

Mitigation Pattern: assertMsg "Delegation must chain to a vetted root namespace" (isVettedNamespace delegationRoot)

Evidence: Discovered by authorization-auditor agent on 2026-03-21. Local test PASSED. Semgrep rule validates.

Checklist: All 7 items auto-checked.

Where PR content comes from (nothing is manual):

PR field	Collected during
Title, type, domain, severity, CWE	Layer 1: agent proposal
Description, mitigation pattern	Layer 3: /integrate-vector sanitization
Test evidence, semgrep evidence	Layer 4: verification run
Applicability statement	Layer 3: sanitization step
Labels	Auto-applied from YAML fields

bastion-status output:

Bastion Status — canton-exchange
Framework version: 2.1.0 (up to date)
Last sync: 2026-03-21

Pending proposals (3):
  VECTOR  AV-048  Canton Topology Delegation Bypass     HIGH   Ready

  RULE    daml-topology-delegation-check                Matches AV-048

Governing Body Review

Proposals arrive fully formed with evidence, test results, and validation — the review burden on the committee is minimal.

ACCEPT if: Applies to any DAML/Canton project, classification is accurate, content is correct and generic, not a duplicate, scoring is reasonable.

REJECT if: Project-specific, incomplete, already covered, scoring inflated.

VARIANT if: Similar to existing content but warrants expansion.
