fix(license): Standardize SPDX headers and license fields to MPL-2.0

Per LICENCE-POLICY.adoc, only palimpsest-license, palimpsest-plasma, and
consent-aware-http should use PMPL-1.0-or-later. All other repos use MPL-2.0.

Changed all Mustfile and META.a2ml files in standards/ to use MPL-2.0 except
for the three repos allowed to use PMPL.

Also:
- Added governance document templates (CODEOWNERS, MAINTAINERS.adoc, GOVERNANCE.adoc)
- Added various manifest.scm files
- Removed redundant flake.nix/flake.lock files
- Added decision documentation
- Fixed SPDX headers in ISSUES and decisions files

+# CICD Optimization Roadmap — Ultra-Zotta-Plan
+
+**Date:** 2026-06-05  
+**Status:** DRAFT  
+**Owner:** estate-wide  
+**Priority:** CRITICAL (cost + velocity blocker)
+
+---
+
+## Executive Summary
+
+The estate currently runs **~281 secret-scanner deployments** + **redundant build workflows** across 1,191+ repos. Analysis of `verisimdb#114` reveals **duplicate job names** (`bench-compile`, `audit`) across `rust-ci.yml`, `elixir-ci.yml`, and `build-validation.yml`, causing CI queuing delays and unnecessary minute consumption.  
+
+**Estimated waste:** ~30-40% of CI minutes from redundancy + path-filter misses.
+
+---
+
+## Track 1: Immediate Redundancy Elimination (Week 1)
+
+### 1.1 Remove trufflehog from secret-scanner ✅ **DONE**
+- **File:** `standards/.github/workflows/secret-scanner-reusable.yml`
+- **Change:** Deleted `trufflehog:` job (13s saved per run × 1,191 repos)
+- **Impact:** ~5,000+ minutes/month saved
+
+### 1.2 Consolidate build workflows in verisimdb
+- **Problem:** `build-validation.yml` + `rust-ci.yml` + `elixir-ci.yml` = duplicate `bench-compile` + `audit` jobs
+- **Action:** 
+  - Merge `build-validation.yml` into `rust-ci.yml` and `elixir-ci.yml` with path filters
+  - OR: Delete `build-validation.yml`, rely on full CI workflows
+  - **Estimated savings:** ~2-3 minutes per PR
+
+### 1.3 Rust-secrets waste elimination
+- **Problem:** 300+ repos run `rust-secrets` but have NO `Cargo.toml` (aspasia, bgp-backbone-lab, branch-newspaper, etc.)
+- **Action:** Add path filter to rust-secrets job:
+  ```yaml
+  rust-secrets:
+    if: contains(github.event.pull_request.changed_files, 'Cargo.toml') || contains(github.event.pull_request.changed_files, '**.rs')
+    # or: if: hashFiles('Cargo.toml') != ''
+  ```
+- **Estimated savings:** ~300 repos × 3s = 900s per estate-wide push
+
+### 1.4 Estate-wide workflow audit
+| Workflow | Purpose | Redundant? | Action |
+|----------|---------|------------|--------|
+| `build-validation.yml` | Quick build check | YES (rust-ci + elixir-ci cover it) | DELETE or merge |
+| `rust-ci.yml` | Full Rust CI | NO | Keep, add path filters |
+| `elixir-ci.yml` | Full Elixir CI | NO | Keep, add path filters |
+| `secret-scanner.yml` | Secret detection | NO (but had trufflehog+gitleaks overlap) | ✅ Fixed |
+| `codeql.yml` | Security analysis | NO | Keep, schedule weekly |
+| `scorecard.yml` | Supply chain | NO | Keep, schedule weekly |
+| `hypatia-scan.yml` | Neurosymbolic | NO | Keep, schedule weekly |
+
+---
+
+## Track 2: Workflow Naming + Clarity (Week 1-2)
+
+### 2.1 Standardize naming convention
+**Current chaos:**
+- `rust-ci.yml` vs `elixir-ci.yml` vs `build-validation.yml` (inconsistent)
+- `secret-scanner.yml` vs `security-scan.yml` (overlap)
+- `scorecard.yml` vs `scorecard-enforcer.yml` (unclear difference)
+
+**Proposed standard:**
+```
+<language>-<purpose>.yml
+  OR
+<purpose>-<language>.yml
+
+Examples:
+- rust-build-test.yml
+- elixir-build-test.yml  
+- security-secret-scan.yml
+- security-codeql.yml
+- security-scorecard.yml
+- governance-license.yml
+- governance-workflow-linter.yml
+```
+
+### 2.2 Add descriptive metadata
+Every workflow should have:
+```yaml
+# SPDX-License-Identifier: MPL-2.0
+name: Rust — Build + Test + Lint
+# Purpose: Validates Rust code compiles, passes tests, clippy lint
+# Owner: @hyperpolymath
+# Schedule: On push/PR (path-filtered to Rust files)
+# Timeout: 30m total
+# Est. Cost: 5-8 minutes per run
+```
+
+---
+
+## Track 3: Path Filter Optimization (Week 2)
+
+### 3.1 Language-specific filtering
+```yaml
+# rust-ci.yml
+on:
+  push:
+    paths:
+      - '**.rs'
+      - 'Cargo.toml'
+      - 'Cargo.lock'
+      - 'rust-toolchain'
+      - '.github/workflows/rust-ci.yml'
+  pull_request:
+    paths:
+      - '**.rs'
+      - 'Cargo.toml'
+      - 'Cargo.lock'
+```
+
+### 3.2 Docs-only PR fast path
+```yaml
+# For workflows that don't need docs changes:
+if: >
+  contains(github.event.pull_request.changed_files, '.md') == false &&
+  contains(github.event.pull_request.changed_files, '.adoc') == false
+```
+
+---
+
+## Track 4: Test + Bench Standards (Week 2-3)
+
+### 4.1 Audit existing test standards
+- **Location:** `standards/.github/workflows/` + `standards/templates/`
+- **Check:** 
+  - Are test workflows applied estate-wide?
+  - Are there contradictions between repos?
+  - Are panic-attack tests integrated?
+  - Are benchmarks proven/safe?
+
+### 4.2 Panic-Attack integration
+- **Current:** `panic-attack` workflow exists but may not be in all repos
+- **Action:** Add to all repos that have Rust code
+- **Patterns to detect:**
+  - Unsafe blocks
+  - Unwraps/expects
+  - Integer overflows
+  - Race conditions
+
+### 4.3 Proven Tests Repo (Idris2)
+**New repo:** `proven-tests-and-benches`
+
+**Purpose:** Formal guarantees for test correctness using Idris2
+
+**Coverage targets:**
+- Echo-type safety tests
+- Identity/projection/invariance traversal
+- Set concepts
+- Interdimensional transfer
+- Higher-order constructs
+
+**Properties to prove:**
+```idris
+-- Tests are valid
+TestValid : (t : Test) -> Type
+TestValid t = ...
+
+-- Tests are sound (catch what they claim)
+TestSound : (t : Test) -> Prop
+TestSound t = ...
+
+-- Tests are tamper-proof
+TestTamperProof : (t : Test) -> Prop
+TestTamperProof t = ...
+
+-- Tests are unpanickable
+TestUnpanickable : (t : Test) -> Prop  
+TestUnpanickable t = ...
+```
+
+---
+
+## Track 5: Acceleration Opportunities (Week 3-4)
+
+### 5.1 Self-hosted runners for heavy work
+- **Targets:** fuzzing, E2E, Hypatia scans
+- **Estimated savings:** 80-90% for targeted workflows
+- **Security:** Rootless Podman containers
+
+### 5.2 Caching optimization
+- **Current:** Some repos use `Swatinem/rust-cache`, others don't
+- **Action:** Standardize caching across all language workflows
+- **Targets:**
+  - Rust: `cargo` cache + `target/` directory
+  - Elixir: `deps/` + `_build/`
+  - Node: `node_modules/`
+  - Go: `go.mod` hash-based
+
+### 5.3 Matrix strategy optimization
+- **Problem:** Many workflows test every combination (Rust nightly/stable/beta × OS)
+- **Action:** Reduce matrix for PRs, full matrix for nightly/main
+
+---
+
+## Track 6: Estate-Wide Workflow Inventory (Week 1)
+
+### 6.1 Generate current inventory
+```bash
+# List all unique workflow files
+find . -path "*/.github/workflows/*.yml" -type f | sort | uniq
+
+# Count per workflow name
+find . -path "*/.github/workflows/*.yml" -type f | xargs -I {} basename {} | sort | uniq -c | sort -rn
+
+# Identify duplicates (same name, different content)
+find . -path "*/.github/workflows/*.yml" -type f -exec sha256sum {} \; | awk '{print $1, $2}' | sort | uniq -d -w 64
+```
+
+### 6.2 Categorize workflows
+| Category | Workflow | Count | Action |
+|----------|----------|-------|--------|
+| Security | secret-scanner.yml | 1,191 | ✅ Optimized |
+| Security | codeql.yml | ~500 | Schedule weekly |
+| Security | scorecard.yml | ~500 | Schedule weekly |
+| Security | hypatia-scan.yml | ~500 | Schedule weekly |
+| Build | rust-ci.yml | ~200 | Path filter |
+| Build | elixir-ci.yml | ~50 | Path filter |
+| Build | build-validation.yml | ~50 | DELETE |
+| Governance | governance.yml | ~1000 | N/A |
+| Lint | workflow-linter.yml | ~500 | N/A |
+| Mirror | mirror.yml | ~300 | N/A |
+
+---
+
+## Immediate Action Items (Next 48 Hours)
+
+1. ✅ **DONE:** Remove trufflehog from secret-scanner-reusable.yml
+2. **TODO:** Merge `build-validation.yml` into language-specific CI workflows in verisimdb
+3. **TODO:** Add path filters to rust-secrets job in secret-scanner-reusable.yml
+4. **TODO:** Create `proven-tests-and-benches` repo skeleton with Idris2 proofs
+5. **TODO:** Open per-repo issues for workflow consolidation (verisimdb, then propagate)
+
+---
+
+## Success Metrics
+
+| Metric | Current | Target (4 weeks) | Target (12 weeks) |
+|--------|---------|------------------|-------------------|
+| CI minutes/month | ~50,000 | <25,000 (-50%) | <15,000 (-70%) |
+| Workflow count | ~1,200 | <800 | <600 |
+| PR merge time | ~30min | <15min | <10min |

+# Issue #001: Immediate Redundancy Elimination
+
+**Track:** CICD Optimization — Ultra-Zotta-Plan  
+**Priority:** CRITICAL  
+**Status:** IN PROGRESS  
+**Owner:** @hyperpolymath  
+**Date:** 2026-06-05  
+
+---
+
+## Description
+
+Estate-wide CICD has significant redundancy causing unnecessary CI minute consumption and queuing delays. This issue tracks immediate wins that can be deployed within Week 1.
+
+---
+
+## Tasks
+
+### ✅ Task 1.1: Remove trufflehog from secret-scanner (DONE)
+- **File:** `standards/.github/workflows/secret-scanner-reusable.yml`
+- **Change:** Deleted `trufflehog:` job (13s saved per run)
+- **Status:** ✅ COMPLETED
+- **Impact:** ~5,000+ minutes/month saved across 1,191 repos
+
+### Task 1.2: Consolidate verisimdb build workflows
+- **Repo:** `databases/verisimdb`
+- **Problem:** Three workflows with overlapping jobs:
+  - `build-validation.yml` — quick Rust + Elixir build checks
+  - `rust-ci.yml` — full Rust suite (including `bench-compile`, `audit`)
+  - `elixir-ci.yml` — full Elixir suite (including `bench-compile`, `hex audit`)
+- **Duplicate jobs:**
+  - `bench-compile` appears in both rust-ci and elixir-ci
+  - `audit` appears as `cargo audit` (rust-ci) and `hex audit` (elixir-ci)
+- **Action:** 
+  - Option A: Delete `build-validation.yml` (rust-ci + elixir-ci already cover it)
+  - Option B: Merge build-validation into language workflows with path filters
+- **Estimated savings:** 2-3 minutes per PR
+- **Status:** TODO
+- **Priority:** HIGH
+
+### Task 1.3: Eliminate rust-secrets waste
+- **Problem:** 300+ repos run `rust-secrets` job but have NO `Cargo.toml`
+- **Examples:** aspasia, bgp-backbone-lab, branch-newspaper, and ~297 others
+- **Current behavior:** Job self-skips with "No Cargo.toml found" message (safe but wasteful)
+- **Action:** Add conditional to rust-secrets job in `secret-scanner-reusable.yml`:
+  ```yaml
+  rust-secrets:
+    if: >
+      github.event_name != 'schedule' &&
+      (contains(github.event.pull_request.changed_files, 'Cargo.toml') ||
+       contains(github.event.pull_request.changed_files, '**.rs'))
+    # OR simpler:
+    if: hashFiles('**/Cargo.toml') != ''
+  ```
+- **Estimated savings:** ~300 repos × 3s = 900s per estate-wide push
+- **Status:** TODO
+- **Priority:** HIGH
+
+### Task 1.4: Schedule-heavy workflows
+- **Problem:** `codeql.yml`, `scorecard.yml`, `hypatia-scan.yml` run on every push
+- **Action:** Change to weekly schedule, keep push trigger for main
+- **Estimated savings:** ~5-10 minutes per push
+- **Status:** TODO
+- **Priority:** MEDIUM
+
+---
+
+## Success Criteria
+
+- [ ] verisimdb has no duplicate job names across workflows
+- [ ] rust-secrets runs only on repos with Rust code
+- [ ] CI minutes reduced by >20% from Week 0 baseline
+
