 Here’s a simple, low‑friction way to keep priorities fresh without constant manual grooming: **let confidence decay over time**.
 ![A small curve sloping down over time, illustrating exponential decay](https://dummyimage.com/800x250/ffffff/000000\&text=confidence\(t\)%20=%20e^{-t/τ})
 # Exponential confidence decay (what & why)
 * **Idea:** Every item (task, lead, bug, doc, hypothesis) has a confidence score that **automatically shrinks with time** if you don’t touch it.
 * **Formula:** `confidence(t) = e^(−t/τ)` where `t` is days since last signal (edit, comment, commit, new data), and **τ (“tau”)** is the decay constant.
 * **Rule of thumb:** With **τ = 30 days**, at **t = 30** the confidence is **e^(−1) ≈ 0.37**—about a **63% drop**. This surfaces long‑ignored items *gradually*, not with harsh “stale/expired” flips.
 # How to use it in practice
 * **Signals that reset t → 0:** comment on the ticket, new benchmark, fresh log sample, doc update, CI run, new market news.
 * **Sort queues by:** `priority × confidence(t)` (or severity × confidence). Quiet items drift down; truly active ones stay up.
 * **Escalation bands:**
  * `>0.6` = green (recently touched)
  * `0.3–0.6` = amber (review soon)
  * `<0.3` = red (poke or close)
 # Quick presets
 * **Fast‑moving queues (incidents, hot leads):** τ = **7–14** days
 * **Engineering tasks / product docs:** τ = **30** days
 * **Research bets / roadmaps:** τ = **60–90** days
 # For your world (Stella Ops + ops/dev work)
 * **Vuln tickets:** `risk_score = CVSS × reachability × e^(−t/30)`
 * **Roadmap epics:** `value_score = impact × e^(−t/60)` to re‑rank quarterly.
 * **Docs:** show a badge “freshness: 42%” derived from last edit age to nudge updates.
 # Minimal implementation sketch
 * Store per‑item: `last_signal_at`, `base_priority`.
 * Compute on read:
  ```
  days = (now - last_signal_at).days
  conf  = exp(-days / tau)
  score = base_priority * conf
  ```
 * Recompute in your API layer or materialize nightly; no cron spam needed.
 If you want, I can draft a tiny C# helper (and SQL snippet) you can drop into your issue service to add `confidence(t)` and color bands to your lists.
 Perfect, let’s turn the idea into something your devs can actually build.
 Below is an implementation plan you can drop into a ticketing/PRD — with clear phases, data model changes, APIs, and some sample code (C# + SQL). I’ll also sprinkle in Stella Ops–specific notes.
 ---
 ## 0. Scope & Objectives
 **Goal:** Introduce `confidence(t)` as an automatic freshness factor that decays with time and is used to rank and highlight work.
 We’ll apply it to:
 * Vulnerabilities (Stella Ops)
 * General issues / tasks / epics
 * (Optional) Docs, leads, hypotheses later
 **Core behavior:**
 * Each item has:
  * A base priority / risk (from severity, business impact, etc.)
  * A timestamp of last signal (meaningful activity)
  * A decay rate τ (tau) in days
 * Effective priority = `base_priority × confidence(t)`
 * `confidence(t) = exp(− t / τ)` where `t` = days since last_signal
 ---
 ## 1. Data Model Changes
 ### 1.1. Add fields to core “work item” tables
 For each relevant table (`Issues`, `Vulnerabilities`, `Epics`, …):
 **New columns:**
 * `base_priority` (FLOAT or INT)
  * Example: 1–100, or derived from severity.
 * `last_signal_at` (DATETIME, NOT NULL, default = `created_at`)
 * `tau_days` (FLOAT, nullable, falls back to type default)
 * (Optional) `confidence_score_cached` (FLOAT, for materialized score)
 * (Optional) `is_confidence_frozen` (BOOL, default FALSE)
  For pinned items that should not decay.
 **Example Postgres migration (Issues):**
 ```sql
 ALTER TABLE issues
  ADD COLUMN base_priority       DOUBLE PRECISION,
  ADD COLUMN last_signal_at      TIMESTAMPTZ NOT NULL DEFAULT NOW(),
  ADD COLUMN tau_days            DOUBLE PRECISION,
  ADD COLUMN confidence_cached   DOUBLE PRECISION,
  ADD COLUMN is_confidence_frozen BOOLEAN NOT NULL DEFAULT FALSE;
 ```
 For Stella Ops:
 ```sql
 ALTER TABLE vulnerabilities
  ADD COLUMN base_risk           DOUBLE PRECISION,
  ADD COLUMN last_signal_at      TIMESTAMPTZ NOT NULL DEFAULT NOW(),
  ADD COLUMN tau_days            DOUBLE PRECISION,
  ADD COLUMN confidence_cached   DOUBLE PRECISION,
  ADD COLUMN is_confidence_frozen BOOLEAN NOT NULL DEFAULT FALSE;
 ```
 ### 1.2. Add a config table for τ per entity type
 ```sql
 CREATE TABLE confidence_decay_config (
  id                SERIAL PRIMARY KEY,
  entity_type       TEXT NOT NULL, -- 'issue', 'vulnerability', 'epic', 'doc'
  tau_days_default  DOUBLE PRECISION NOT NULL,
  created_at        TIMESTAMPTZ NOT NULL DEFAULT NOW(),
  updated_at        TIMESTAMPTZ NOT NULL DEFAULT NOW()
 );
 INSERT INTO confidence_decay_config (entity_type, tau_days_default) VALUES
 ('incident', 7),
 ('vulnerability', 30),
 ('issue', 30),
 ('epic', 60),
 ('doc', 90);
 ```
 ---
 ## 2. Define “signal” events & instrumentation
 We need a standardized way to say: “this item got activity → reset last_signal_at”.
 ### 2.1. Signals that should reset `last_signal_at`
 For **issues / epics:**
 * New comment
 * Status change (e.g., Open → In Progress)
 * Field change that matters (severity, owner, milestone)
 * Attachment added
 * Link to PR added or updated
 * New CI failure linked
 For **vulnerabilities (Stella Ops):**
 * New scanner result attached or status updated (e.g., “Verified”, “False Positive”)
 * New evidence (PoC, exploit notes)
 * SLA override change
 * Assignment / ownership change
 * Integration events (e.g., PR merge that references the vuln)
 For **docs (if you do it):**
 * Any edit
 * Comment/annotation
 ### 2.2. Implement a shared helper to record a signal
 **Service-level helper (pseudocode / C#-ish):**
 ```csharp
 public interface IConfidenceSignalService
 {
    Task RecordSignalAsync(WorkItemType type, Guid itemId, DateTime? signalTimeUtc = null);
 }
 public class ConfidenceSignalService : IConfidenceSignalService
 {
    private readonly IWorkItemRepository _repo;
    private readonly IConfidenceConfigService _config;
    public async Task RecordSignalAsync(WorkItemType type, Guid itemId, DateTime? signalTimeUtc = null)
    {
        var now = signalTimeUtc ?? DateTime.UtcNow;
        var item = await _repo.GetByIdAsync(type, itemId);
        if (item == null) return;
        item.LastSignalAt = now;
        if (item.TauDays == null)
        {
            item.TauDays = await _config.GetDefaultTauAsync(type);
        }
        await _repo.UpdateAsync(item);
    }
 }
 ```
 ### 2.3. Wire signals into existing flows
 Create small tasks for devs like:
 * **ISS-01:** Call `RecordSignalAsync` on:
  * New issue comment handler
  * Issue status update handler
  * Issue field update handler (severity/priority/owner)
 * **VULN-01:** Call `RecordSignalAsync` when:
  * New scanner result ingested for a vuln
  * Vulnerability status, SLA, or owner changes
  * New exploit evidence is attached
 ---
 ## 3. Confidence & scoring calculation
 ### 3.1. Shared confidence function
 Definition:
 ```csharp
 public static class ConfidenceMath
 {
    // t = days since last signal
    public static double ConfidenceScore(DateTime lastSignalAtUtc, double tauDays, DateTime? nowUtc = null)
    {
        var now = nowUtc ?? DateTime.UtcNow;
        var tDays = (now - lastSignalAtUtc).TotalDays;
        if (tDays <= 0) return 1.0;
        if (tauDays <= 0) return 1.0; // guard / fallback
        var score = Math.Exp(-tDays / tauDays);
        // Optional: never drop below a tiny floor, so items never "disappear"
        const double floor = 0.01;
        return Math.Max(score, floor);
    }
 }
 ```
 ### 3.2. Effective priority formulas
 **Generic issues / tasks:**
 ```csharp
 double effectiveScore = issue.BasePriority * ConfidenceMath.ConfidenceScore(issue.LastSignalAt, issue.TauDays ?? defaultTau);
 ```
 **Vulnerabilities (Stella Ops):**
 Let’s define:
 * `severity_weight`: map CVSS or severity string to numeric (e.g. Critical=100, High=80, Medium=50, Low=20).
 * `reachability`: 0–1 (e.g. from your reachability analysis).
 * `exploitability`: 0–1 (optional, based on known exploits).
 * `confidence`: as above.
 ```csharp
 double baseRisk = severityWeight * reachability * exploitability; // or simpler: severityWeight * reachability
 double conf = ConfidenceMath.ConfidenceScore(vuln.LastSignalAt, vuln.TauDays ?? defaultTau);
 double effectiveRisk = baseRisk * conf;
 ```
 Store `baseRisk` → `vulnerabilities.base_risk`, and compute `effectiveRisk` on the fly or via job.
 ### 3.3. SQL implementation (optional for server-side sorting)
 **Postgres example:**
 ```sql
 -- t_days = age in days
 -- tau = tau_days
 -- score = exp(-t_days / tau)
 SELECT
  i.*,
  i.base_priority * 
    GREATEST(
      EXP(- EXTRACT(EPOCH FROM (NOW() - i.last_signal_at)) / (86400 * COALESCE(i.tau_days, 30))),
      0.01
    ) AS effective_priority
 FROM issues i
 ORDER BY effective_priority DESC;
 ```
 You can wrap that in a view:
 ```sql
 CREATE VIEW issues_with_confidence AS
 SELECT
  i.*,
  GREATEST(
    EXP(- EXTRACT(EPOCH FROM (NOW() - i.last_signal_at)) / (86400 * COALESCE(i.tau_days, 30))),
    0.01
  ) AS confidence,
  i.base_priority *
    GREATEST(
      EXP(- EXTRACT(EPOCH FROM (NOW() - i.last_signal_at)) / (86400 * COALESCE(i.tau_days, 30))),
      0.01
    ) AS effective_priority
 FROM issues i;
 ```
 ---
 ## 4. Caching & performance
 You have two options:
 ### 4.1. Compute on read (simplest to start)
 * Use the helper function in your service layer or a DB view.
 * Pros:
  * No jobs, always fresh.
 * Cons:
  * Slight CPU cost on heavy lists.
 **Plan:** Start with this. If you see perf issues, move to 4.2.
 ### 4.2. Periodic materialization job (optional later)
 Add a scheduled job (e.g. hourly) that:
 1. Selects all active items.
 2. Computes `confidence_score` and `effective_priority`.
 3. Writes to `confidence_cached` and `effective_priority_cached` (if you add such a column).
 Service then sorts by cached values.
 ---
 ## 5. Backfill & migration
 ### 5.1. Initial backfill script
 For existing records:
 * If `last_signal_at` is NULL → set to `created_at`.
 * Derive `base_priority` / `base_risk` from existing severity fields.
 * Set `tau_days` from config.
 **Example:**
 ```sql
 UPDATE issues
 SET last_signal_at = created_at
 WHERE last_signal_at IS NULL;
 UPDATE issues
 SET base_priority = CASE severity
  WHEN 'critical' THEN 100
  WHEN 'high'     THEN 80
  WHEN 'medium'   THEN 50
  WHEN 'low'      THEN 20
  ELSE 10
 END
 WHERE base_priority IS NULL;
 UPDATE issues i
 SET tau_days = c.tau_days_default
 FROM confidence_decay_config c
 WHERE c.entity_type = 'issue'
  AND i.tau_days IS NULL;
 ```
 Do similarly for `vulnerabilities` using severity / CVSS.
 ### 5.2. Sanity checks
 Add a small script/test to verify:
 * Newly created items → `confidence ≈ 1.0`.
 * 30-day-old items with τ=30 → `confidence ≈ 0.37`.
 * Ordering changes when you edit/comment on items.
 ---
 ## 6. API & Query Layer
 ### 6.1. New sorting options
 Update list APIs:
 * Accept parameter: `sort=effective_priority` or `sort=confidence`.
 * Default sort for some views:
  * Vulnerabilities backlog: `sort=effective_risk` (risk × confidence).
  * Issues backlog: `sort=effective_priority`.
 **Example REST API contract:**
 `GET /api/issues?sort=effective_priority&state=open`
 **Response fields (additions):**
 ```json
 {
  "id": "ISS-123",
  "title": "Fix login bug",
  "base_priority": 80,
  "last_signal_at": "2025-11-01T10:00:00Z",
  "tau_days": 30,
  "confidence": 0.63,
  "effective_priority": 50.4,
  "confidence_band": "amber"
 }
 ```
 ### 6.2. Confidence banding (for UI)
 Define bands server-side (easy to change):
 * Green: `confidence >= 0.6`
 * Amber: `0.3 ≤ confidence < 0.6`
 * Red: `confidence < 0.3`
 You can compute on server:
 ```csharp
 string ConfidenceBand(double confidence) =>
    confidence >= 0.6 ? "green"
  : confidence >= 0.3 ? "amber"
  : "red";
 ```
 ---
 ## 7. UI / UX changes
 ### 7.1. List views (issues / vulns / epics)
 For each item row:
 * Show a small freshness pill:
  * Text: `Active`, `Review soon`, `Stale`
  * Derived from confidence band.
  * Tooltip:
    * “Confidence 78%. Last activity 3 days ago. τ = 30 days.”
 * Sort default: by `effective_priority` / `effective_risk`.
 * Filters:
  * `Freshness: [All | Active | Review soon | Stale]`
  * Optionally: “Show stale only” toggle.
 **Example labels:**
 * Green: “Active (confidence 82%)”
 * Amber: “Review soon (confidence 45%)”
 * Red: “Stale (confidence 18%)”
 ### 7.2. Detail views
 On an issue / vuln page:
 * Add a “Confidence” section:
  * “Confidence: **52%**”
  * “Last signal: **12 days ago**”
  * “Decay τ: **30 days**”
  * “Effective priority: **Base 80 × 0.52 = 42**”
 * (Optional) small mini-chart (text-only or simple bar) showing approximate decay, but not necessary for first iteration.
 ### 7.3. Admin / settings UI
 Add an internal settings page:
 * Table of entity types with editable τ:
  | Entity type   | τ (days) | Notes                        |
  | ------------- | -------- | ---------------------------- |
  | Incident      | 7        | Fast-moving                  |
  | Vulnerability | 30       | Standard risk review cadence |
  | Issue         | 30       | Sprint-level decay           |
  | Epic          | 60       | Quarterly                    |
  | Doc           | 90       | Slow decay                   |
 * Optionally: toggle to pin item (`is_confidence_frozen`) from UI.
 ---
 ## 8. Stella Ops–specific behavior
 For vulnerabilities:
 ### 8.1. Base risk calculation
 Ingested fields you likely already have:
 * `cvss_score` or `severity`
 * `reachable` (true/false or numeric)
 * (Optional) `exploit_available` (bool) or exploitability score
 * `asset_criticality` (1–5)
 Define `base_risk` as:
 ```text
 severity_weight = f(cvss_score or severity)
 reachability    = reachable ? 1.0 : 0.5   -- example
 exploitability  = exploit_available ? 1.0 : 0.7
 asset_factor    = 0.5 + 0.1 * asset_criticality  -- 1 → 1.0, 5 → 1.5
 base_risk = severity_weight * reachability * exploitability * asset_factor
 ```
 Store `base_risk` on vuln row.
 Then:
 ```text
 effective_risk = base_risk * confidence(t)
 ```
 Use `effective_risk` for backlog ordering and SLAs dashboards.
 ### 8.2. Signals for vulns
 Make sure these all call `RecordSignalAsync(Vulnerability, vulnId)`:
 * New scan result for same vuln (re-detected).
 * Change status to “In Progress”, “Ready for Deploy”, “Verified Fixed”, etc.
 * Assigning an owner.
 * Attaching PoC / exploit details.
 ### 8.3. Vuln UI copy ideas
 * Pill text:
  * “Risk: 850 (confidence 68%)”
  * “Last analyst activity 11 days ago”
 * In backlog view: show **Effective Risk** as main sort, with a smaller subtext “Base 1200 × Confidence 71%”.
 ---
 ## 9. Rollout plan
 ### Phase 1 – Infrastructure (backend-only)
 * [ ] DB migrations & config table
 * [ ] Implement `ConfidenceMath` and helper functions
 * [ ] Implement `IConfidenceSignalService`
 * [ ] Wire signals into key flows (comments, state changes, scanner ingestion)
 * [ ] Add `confidence` and `effective_priority/risk` to API responses
 * [ ] Backfill script + dry run in staging
 ### Phase 2 – Internal UI & feature flag
 * [ ] Add optional sorting by effective score to internal/staff views
 * [ ] Add confidence pill (hidden behind feature flag `confidence_decay_v1`)
 * [ ] Dogfood internally:
  * Do items bubble up/down as expected?
  * Are any items “disappearing” because decay is too aggressive?
 ### Phase 3 – Parameter tuning
 * [ ] Adjust τ per type based on feedback:
  * If things decay too fast → increase τ
  * If queues rarely change → decrease τ
 * [ ] Decide on confidence floor (0.01? 0.05?) so nothing goes to literal 0.
 ### Phase 4 – General release
 * [ ] Make effective score the default sort for key views:
  * Vulnerabilities backlog
  * Issues backlog
 * [ ] Document behavior for users (help center / inline tooltip)
 * [ ] Add admin UI to tweak τ per entity type.
 ---
 ## 10. Edge cases & safeguards
 * **New items**
  * `last_signal_at = created_at`, confidence = 1.0.
 * **Pinned items**
  * If `is_confidence_frozen = true` → treat confidence as 1.0.
 * **Items without τ**
  * Always fallback to entity type default.
 * **Timezones**
  * Always store & compute in UTC.
 * **Very old items**
  * Floor the confidence so they’re still visible when explicitly searched.
 ---
 If you want, I can turn this into:
 * A short **technical design doc** (with sections: Problem, Proposal, Alternatives, Rollout).
 * Or a **set of Jira tickets** grouped by backend / frontend / infra that your team can pick up directly.

 # Plugin Architecture & Extensibility Patterns
 **Version:** 1.0
 **Date:** 2025-11-28
 **Status:** Canonical
 This advisory consolidates the extensibility patterns used across Stella Ops modules, providing a unified view for architects and developers implementing custom integrations.
 ---
 ## 1. Overview
 Stella Ops uses a **plugin-based architecture** enabling customers and partners to extend functionality without modifying core code. The platform supports three primary extension types:
 | Type | Module | Purpose | Examples |
 |------|--------|---------|----------|
 | **Connectors** | Concelier, Excititor | Ingest/export data from external sources | NVD, OSV, vendor VEX feeds |
 | **Plugins** | Authority, Scanner | Extend runtime behavior | LDAP auth, custom analyzers |
 | **Analyzers** | Scanner | Add detection capabilities | Language-specific, binary analysis |
 ---
 ## 2. Core Principles
 ### 2.1 Determinism
 All plugins must produce **deterministic outputs** for identical inputs:
 - No global state between invocations
 - Timestamps in UTC ISO-8601
 - Stable ordering of collections
 - Reproducible hashing with documented algorithms
 ### 2.2 Offline-First
 Plugins must function in **air-gapped environments**:
 - No network access unless explicitly configured
 - Local configuration and secrets
 - Bundled dependencies (no runtime downloads)
 - Offline-capable credential stores
 ### 2.3 Restart-Safe
 Plugins load at **service startup only**:
 - No hot-reload (security/determinism trade-off)
 - Configuration changes require restart
 - State persists in external stores (MongoDB, filesystem)
 ---
 ## 3. Plugin Lifecycle

 ```
 See: `docs/modules/scanner/guides/surface-validation-extensibility.md`
 ---
 ## 7. Manifest Structure
 All plugins use a standard manifest format:
 ```json
 {
  "pluginId": "example-plugin",
  "version": "1.0.0",
  "assemblyName": "StellaOps.Module.Plugin.Example",
  "hostVersion": ">=2.0.0",
  "capabilities": ["capability1", "capability2"],
  "configuration": {
    "requiredSettings": ["setting1"],
    "optionalSettings": ["setting2"]
  },
  "dependencies": {
    "packages": ["Dependency.Package@1.0.0"]
  }
 }
 ```
 ---
 ## 8. Security Considerations
 ### 8.1 Assembly Isolation
 - Plugins load in dedicated assembly contexts
 - Host enforces capability-based access control
 - Network access requires explicit configuration
 ### 8.2 Configuration Validation
 - Unknown capability tokens rejected at startup
 - Path traversal in relative paths blocked
 - Secrets never logged or exposed in diagnostics
 ### 8.3 Audit Trail
 - Plugin loading events logged with assembly hash
 - Configuration changes recorded
 - Runtime errors captured with context
 ---
 ## 9. Offline Kit Integration
 Plugins must support offline distribution:
 ```
 offline-kit/
 ├── plugins/
 │   ├── authority/
 │   │   ├── StellaOps.Authority.Plugin.Ldap.dll
 │   │   └── manifest.json
 │   ├── scanner/
 │   │   ├── StellaOps.Scanner.Analyzer.Custom.dll
 │   │   └── manifest.json
 │   └── checksums.sha256
 ├── config/
 │   └── plugins.yaml
 └── MANIFEST.json
 ```
 ### 9.1 Checksum Verification
 All plugin assemblies verified against `checksums.sha256` before loading.
 ### 9.2 Version Compatibility
 Host rejects plugins with incompatible `hostVersion` requirements.
 ---
 ## 10. Testing Requirements
 ### 10.1 Unit Tests
 - Registrar binds options correctly
 - Services resolve from DI container
 - Capability metadata accurate
 ### 10.2 Integration Tests
 - Plugin loads in host process
 - Health checks pass
 - Functionality works end-to-end
 ### 10.3 Test Helpers
 ```csharp
 // Use StellaOps.Plugin.Tests helpers
 var host = new PluginTestHost()
    .WithPlugin<MyPlugin>()
    .WithConfiguration(config)
    .Build();
 var plugin = host.GetRequiredService<IMyPlugin>();
 var result = await plugin.DoSomethingAsync();
 ```

 # Sovereign Crypto for Regional Compliance
 **Version:** 1.0
 **Date:** 2025-11-28
 **Status:** Canonical
 This advisory defines the product rationale, implementation strategy, and compliance mapping for regional cryptography support in Stella Ops, enabling deployments in jurisdictions requiring eIDAS, FIPS, GOST, or Chinese SM algorithms.
 ---
 ## 1. Executive Summary
 Stella Ops must support **sovereign-ready cryptography** to serve customers in regulated environments where standard cryptographic algorithms are insufficient or prohibited. This includes:
 - **EU/eIDAS**: Qualified electronic signatures with HSM-backed keys
 - **US/FIPS 140-2/3**: Federal deployments requiring validated cryptographic modules
 - **Russia/GOST**: CryptoPro CSP and GOST R 34.10-2012/34.11-2012 algorithms
 - **China/SM**: SM2 (signing), SM3 (hashing), SM4 (encryption) national standards
 The implementation uses a **provider registry pattern** allowing runtime selection of cryptographic backends without code changes.
 ---
 ## 2. Market Drivers
 ### 2.1 Target Segments
 | Segment | Crypto Requirements | Market Size |
 |---------|---------------------|-------------|
 | **EU Government/Critical Infrastructure** | eIDAS QES, qualified timestamps | Large (EU Digital Identity Wallet mandate) |
 | **US Federal/Defense** | FIPS 140-2/3 validated modules | Large (FedRAMP, CMMC) |
 | **Russian Enterprise** | GOST algorithms, CryptoPro CSP | Medium (domestic compliance) |
 | **Chinese SOE/Government** | SM2/SM3/SM4 algorithms | Large (mandatory for PRC government) |
 ### 2.2 Competitive Positioning
 Most vulnerability scanning tools (Snyk, Trivy, Grype) do not offer sovereign crypto options. Anchore Enterprise provides FIPS builds. Stella Ops can differentiate by supporting **all major regional standards** through a unified provider registry.
 ---
 ## 3. Technical Architecture
 ### 3.1 Provider Registry Pattern
 The `ICryptoProviderRegistry` abstraction enables runtime selection of cryptographic implementations:
 ```

 2. **Timestamps in UTC ISO-8601** format
 3. **Profile names and provider IDs in lowercase ASCII**
 4. **Audit material includes provider version and configuration hash**
 For algorithms with inherent randomness (ECDSA k-value, SM2), determinism applies to verification, not signature bytes.
 ---
 ## 7. Offline/Air-Gap Support
 Sovereign deployments often require air-gapped operation:
 | Feature | Offline Support |
 |---------|----------------|
 | Provider initialization | Local configuration only |
 | Key storage | Local HSM or file-based |
 | Certificate validation | Offline CRL/OCSP stapling |
 | Timestamp authority | Embedded timestamps or offline TSA |
 | Algorithm updates | Bundled in RootPack distributions |
 ---

 | GOST/OpenSSL | Linux + GOST engine | Opt-in pipeline |
 | FIPS | Linux + FIPS module | Opt-in pipeline |
 | SM | Linux + Tongsuo | Future |
 ### 8.3 Compliance Validation
 - NIST CAVP vectors for FIPS algorithms
 - GOST test vectors from TC 26
 - SM test vectors from GM/T standards
 ---
 ## 9. Distribution & Licensing
 ### 9.1 RootPack Bundles
 | Bundle | Contents | Distribution |
 |--------|----------|--------------|
 | `rootpack-default` | Standard algorithms only | Public |
 | `rootpack-ru` | GOST providers + CryptoPro plugin | Restricted (RU customers) |
 | `rootpack-cn` | SM providers + Tongsuo | Restricted (CN customers) |
 | `rootpack-fips` | FIPS-validated binaries | Enterprise only |
 ### 9.2 Licensing Considerations
 - CryptoPro CSP requires customer license

 - **Sender Constraints** - DPoP or mTLS binding prevents token theft
 - **Fine-Grained Scopes** - 65+ scopes with role bundles
 - **Multi-Tenant Isolation** - Tenant claims enforced throughout
 - **Delegated Service Accounts** - Automation without credential exposure
 - **Sovereign Crypto Support** - Configurable signing algorithms per profile
 ---
 ## 2. Market Drivers
 ### 2.1 Target Segments
 | Segment | Authentication Requirements | Use Case |
 |---------|---------------------------|----------|
 | **Enterprise** | SSO/SAML integration, MFA | Corporate security policies |
 | **Government** | CAC/PIV, FIPS validation | Federal compliance |
 | **Financial Services** | Strong auth, audit trails | SOC 2, PCI-DSS |
 | **Healthcare** | HIPAA access controls | PHI protection |
 ### 2.2 Competitive Positioning
 Most vulnerability scanning tools rely on basic API keys. Stella Ops differentiates with:

 - **Fine-grained RBAC** with 65+ scopes
 - **Cryptographic binding** (DPoP/mTLS) prevents token theft
 - **Deterministic revocation bundles** for offline verification
 - **Plugin extensibility** for custom identity providers
 ---
 ## 3. Token Model
 ### 3.1 Three-Token System
 | Token | Lifetime | Purpose | Binding |
 |-------|----------|---------|---------|
 | **License Token (LT)** | Long-lived | Cloud licensing enrollment | Installation |
 | **Proof-of-Entitlement (PoE)** | Medium | License validation | Installation key |
 | **Operational Token (OpTok)** | 2-5 min | Runtime authentication | DPoP/mTLS |
 ### 3.2 Operational Token Structure
 **Registered Claims:**
 ```json
 {
  "iss": "https://authority.example.com",
  "sub": "client-id-or-user-id",
  "aud": "signer|scanner|attestor|concelier|...",
  "exp": 1732881600,
  "iat": 1732881300,
  "nbf": 1732881270,
  "jti": "uuid",
  "scope": "scanner.scan scanner.export signer.sign"
 }
 ```
 **Sender Constraint Claims:**
 ```json
 {
  "cnf": {
    "jkt": "base64url(SHA-256(JWK))",     // DPoP binding
    "x5t#S256": "base64url(SHA-256(cert))" // mTLS binding
  }
 }
 ```
 **Tenant & Context Claims:**
 ```json
 {
  "tid": "tenant-id",
  "inst": "installation-id",
  "roles": ["svc.scanner", "svc.signer"],
  "plan": "enterprise"
 }
 ```
 ### 3.3 Sender Constraints
 **DPoP (Demonstration of Proof-of-Possession):**
 1. Client generates ephemeral JWK keypair
 2. Client sends DPoP proof header with `htm`, `htu`, `iat`, `jti`
 3. Authority validates and stamps token with `cnf.jkt`
 4. Resource servers verify same key on each request
 5. Nonce challenges available for high-value audiences
 **mTLS (Mutual TLS):**
 1. Client presents certificate at TLS handshake
 2. Authority validates and binds to `cnf.x5t#S256`
 3. Resource servers verify same cert on each request
 4. Required for high-value audiences (signer, attestor)
 ---

 ## 5. Multi-Tenant Isolation
 ### 5.1 Tenant Claim Enforcement
 **Token Issuance:**
 - Authority normalizes tenant: `trim().ToLowerInvariant()`
 - Tokens include `tid` (tenant ID) and `inst` (installation ID)
 - Cross-tenant isolation enforced at issuance
 **Propagation:**
 - API Gateway forwards `tid` as `X-Stella-Tenant` header
 - Downstream services reject requests without header
 - All data stamped with tenant identifier
 **Scope Enforcement:**
 - Ingestion scopes require tenant claim
 - `aoc:verify` pairing required for verification scopes
 - Cross-tenant replay rejected
 ### 5.2 Cross-Tenant Operations
 For platform operators with `tenant:admin`:
 - Switch tenants via `/authority/tenant/switch`
 - CLI `--tenant <id>` override
 - Delegated token exchange for automation
 - Full audit trail of tenant switches
 ---
 ## 6. Advanced Token Features
 ### 6.1 Delegated Service Accounts
 ```yaml
 delegation:
  quotas:
    maxActiveTokens: 50
  serviceAccounts:
    - accountId: "svc-observer"
      tenant: "tenant-default"
      displayName: "Observability Exporter"
      allowedScopes: ["jobs:read", "findings:read"]
      authorizedClients: ["export-center-worker"]
 ```
 **Token Shape:**
 - Includes `stellaops:service_account` claim
 - `act` claim describes caller hierarchy
 - Quota enforcement per tenant/account
 ### 6.2 Fresh Auth Window (5 Minutes)
 Required for high-privilege operations:
 - Policy publish/promote
 - Pack approvals
 - Incident mode activation
 - Operator actions
 **Token must include:**
 - `auth_time` within 5 minutes of request
 - Interactive authentication (password/device-code)
 ### 6.3 ABAC Attributes (Vuln Explorer)
 Tokens can carry attribute-based filters:
 - `stellaops:vuln_env` - Environment filter
 - `stellaops:vuln_owner` - Team/owner filter
 - `stellaops:vuln_business_tier` - Criticality tier
 ---
 ## 7. Implementation Strategy
 ### 7.1 Phase 1: Core Token Infrastructure (Complete)
 - [x] DPoP validation on all `/token` grants
 - [x] mTLS binding for refresh grants
 - [x] Sealed-mode CI gating
 - [x] Pack signing policies and RBAC
 - [x] LDAP plugin with claims enricher
 ### 7.2 Phase 2: Sovereign Crypto (In Progress)

 └── MANIFEST.json                  # Kit manifest with hashes
 ```
 ### 8.2 Import Workflow
 1. **Verify MANIFEST.json** signature against bundled TUF root
 2. **Validate each artifact** hash matches manifest
 3. **Check time anchor freshness** against configured tolerance
 4. **Import to local stores** (Concelier, Excititor, Evidence Locker)
 5. **Record import event** with provenance in Timeline
 ---
 ## 9. Verification Workflow
 ### 9.1 Online Verification
 1. Fetch bundle from registry/export center
 2. Verify DSSE signature against JWKS
 3. Validate TUF metadata chain
 4. Check Rekor transparency log (if present)
 5. Verify time anchor freshness
 ### 9.2 Offline Verification
 1. Extract bundle and TUF metadata
 2. Verify DSSE signature against bundled public key
 3. Validate all file hashes match manifest
 4. Check time anchor against local clock + tolerance
 5. Record verification result in local audit log
 ---
 ## 10. Security Considerations
 ### 10.1 Key Protection
 - Root keys stored in HSM or offline cold storage
 - Online keys rotated automatically per TUF policy
 - Key ceremonies documented and audited
 ### 10.2 Rollback Protection
 - TUF timestamp/snapshot prevent rollback attacks
 - Generation numbers monotonically increasing
 - Stale bundles rejected based on time anchor
 ### 10.3 Tampering Detection
 - DSSE signature covers entire manifest
 - Each file has individual hash verification
 - Merkle tree optional for large bundles

 # Task Pack Orchestration and Automation
 **Version:** 1.0
 **Date:** 2025-11-29
 **Status:** Canonical
 This advisory defines the product rationale, DSL semantics, and implementation strategy for the TaskRunner module, covering pack manifest structure, execution semantics, approval workflows, and evidence capture.
 ---
 ## 1. Executive Summary
 The TaskRunner provides **deterministic, auditable automation** for security workflows. Key capabilities:
 - **Task Pack DSL** - Declarative YAML manifests for multi-step workflows
 - **Approval Gates** - Human-in-the-loop checkpoints with Authority integration
 - **Deterministic Execution** - Plan hash verification prevents runtime divergence
 - **Evidence Capture** - DSSE attestations for provenance and audit
 - **Air-Gap Support** - Sealed-mode validation for offline installations
 ---
 ## 2. Market Drivers
 ### 2.1 Target Segments
 | Segment | Automation Requirements | Use Case |
 |---------|------------------------|----------|
 | **Enterprise Security** | Approval workflows for vulnerability remediation | Change advisory board gates |
 | **DevSecOps** | CI/CD pipeline integration | Automated policy enforcement |
 | **Compliance Teams** | Auditable execution with evidence | SOC 2, FedRAMP documentation |
 | **MSP/MSSP** | Multi-tenant orchestration | Managed security services |
 ### 2.2 Competitive Positioning
 Most vulnerability scanning tools lack built-in orchestration. Stella Ops differentiates with:
 - **Declarative task packs** with schema validation
 - **Cryptographic plan verification** (plan hash binding)
 - **Native approval gates** with Authority token integration
 - **Evidence attestations** for audit trails
 - **Sealed-mode enforcement** for air-gapped environments
 ---

 {
  "payloadType": "application/vnd.stellaops.pack-run+json",
  "payload": {
    "runId": "abc123...",
    "packName": "vulnerability-scan-and-report",
    "packVersion": "1.2.0",
    "planHash": "sha256:def456...",
    "inputs": {
      "imageRef": { "value": "nginx:latest", "digest": "sha256:..." }
    },

      { "name": "scanReport", "digest": "sha256:..." }
    ],
    "steps": [
      { "id": "scan", "status": "completed", "duration": 45.2 }
    ],
    "completedAt": "2025-11-29T12:30:00Z"
  },
  "signatures": [...]
 }
 ```
 ### 8.2 Evidence Bundle
 Task pack runs produce evidence bundles containing:
 - Pack manifest (signed)
 - Input values (redacted secrets)
 - Output artifacts
 - Step transcripts
 - DSSE attestation
 ---
 ## 9. Determinism Requirements
 All TaskRunner operations must maintain determinism:
 1. **Plan hash binding** - Runtime graph must match computed plan hash
 2. **Stable step ordering** - Dependencies resolve deterministically
 3. **Expression evaluation** - Same inputs produce same resolved values
 4. **Timestamps in UTC** - All logs and events use ISO-8601 UTC
 5. **Secret masking** - Secrets never appear in logs or evidence
 ---
 ## 10. RBAC & Scopes
 | Scope | Purpose |
 |-------|---------|
 | `packs.read` | Discover/download packs |
 | `packs.write` | Publish/update packs (requires signature) |
 | `packs.run` | Execute packs via CLI/TaskRunner |
 | `packs.approve` | Fulfill approval gates |
 **Approval Token Requirements:**
 - `pack_run_id`, `pack_gate_id`, `pack_plan_hash` are mandatory
 - Token must be fresh (within 5-minute auth window)

 ## Known Issues (Non-Blocking)
 **Unicode Encoding Inconsistency:**
 Several filenames use en-dash (U+2011) instead of regular hyphen (-). This may cause cross-platform issues but does not affect content discovery. Files affected:
 - `26-Nov-2025 - Handling Rekor v2 and DSSE Air‑Gap Limits.md`
 - `27-Nov-2025 - Blueprint for a 2026‑Ready Scanner.md`
 - `27-Nov-2025 - Deep Architecture Brief - SBOM‑First, VEX‑Ready Spine.md`
 **Archived Duplicate:**
 `archived/17-Nov-2025 - SBOM-Provenance-Spine.md` and `archived/18-Nov-2025 - SBOM-Provenance-Spine.md` are potential duplicates. The 18-Nov version is likely canonical.

 # Orchestrator Service GA Checklist
 > Pre-release validation checklist for StellaOps Orchestrator Service.
 > All items must be verified before promoting to `stable` channel.
 ## Build & Packaging
 - [ ] Container images build successfully for all target architectures (amd64, arm64)
 - [ ] Multi-stage Dockerfile produces minimal runtime images (<100MB compressed)
 - [ ] OCI labels include version, git SHA, and license metadata
 - [ ] HEALTHCHECK directive validates endpoint availability
 - [ ] Build is reproducible (same inputs produce byte-identical outputs)
 - [ ] SBOM generated and attached to container images (SPDX 3.0.1 or CycloneDX 1.6)
 - [ ] Provenance attestation generated per SLSA v1 specification
 - [ ] Air-gap bundle script creates valid offline deployment package
 ## Security
 - [ ] Container runs as non-root user (UID 1000+)
 - [ ] No secrets baked into container image layers
 - [ ] Base image digest-pinned to known-good version
 - [ ] Vulnerability scan passes with no HIGH/CRITICAL unfixed CVEs
 - [ ] TLS 1.3 enforced for all external endpoints
 - [ ] Authority JWT validation enabled and tested
 - [ ] Tenant isolation enforced at API and storage layers
 - [ ] Sensitive configuration loaded from Kubernetes secrets only
 ## Functional
 - [ ] Job scheduling CRUD operations work correctly
 - [ ] Cron expression parsing handles edge cases (DST, leap years)
 - [ ] DAG planning respects dependency ordering
 - [ ] Dead letter queue captures failed jobs with full context
 - [ ] Backfill API handles large date ranges without OOM
 - [ ] Worker heartbeat detection marks stale jobs correctly
 - [ ] Rate limiting and concurrency limits enforced per tenant
 ## Performance & Scale

 - [ ] Dispatch latency P95 < 150ms under normal load
 - [ ] Queue depth metrics exposed for autoscaling (KEDA/HPA)
 - [ ] Load shedding activates at configured thresholds
 - [ ] Database connection pooling sized appropriately
 - [ ] Memory usage stable under sustained load (no leaks)
 ## Observability
 - [ ] Structured logging with correlation IDs enabled
 - [ ] OpenTelemetry traces exported to configured endpoint
 - [ ] Prometheus metrics exposed at `/metrics` endpoint
 - [ ] Health probes respond correctly:
  - `/healthz` - basic liveness
  - `/livez` - deep liveness with dependency checks
  - `/readyz` - readiness for traffic
  - `/startupz` - startup completion check
 - [ ] Autoscaling metrics endpoint returns valid JSON
 ## Deployment
 - [ ] Helm values overlay tested with production-like configuration
 - [ ] PostgreSQL schema migrations run idempotently
 - [ ] Rolling update strategy configured (maxSurge/maxUnavailable)
 - [ ] Pod disruption budget prevents full outage
 - [ ] Resource requests/limits appropriate for target workload
 - [ ] Network policies restrict traffic to required paths only
 - [ ] Service mesh (Istio/Linkerd) integration tested if applicable
 ## Documentation
 - [ ] Architecture document updated in `docs/modules/orchestrator/`
 - [ ] API reference generated from OpenAPI spec
 - [ ] Runbook for common operations (restart, scale, failover)
 - [ ] Troubleshooting guide for known issues
 - [ ] Upgrade path documented from previous versions
 ## Testing
 - [ ] Unit tests pass (100% of Core, 80%+ of Infrastructure)
 - [ ] Integration tests pass against real PostgreSQL
 - [ ] Performance benchmarks meet targets
 - [ ] Chaos testing validates graceful degradation
 - [ ] E2E tests cover critical user journeys
 ## Compliance
 - [ ] AGPL-3.0-or-later license headers in all source files
 - [ ] Third-party license notices collected and bundled
 - [ ] Attestation chain verifiable via `stella attest verify`
 - [ ] Air-gap deployment tested in isolated network
 - [ ] CryptoProfile compatibility verified (FIPS/eIDAS if required)
