Add unit and integration tests for VexCandidateEmitter and SmartDiff repositories

- Implemented comprehensive unit tests for VexCandidateEmitter to validate candidate emission logic based on various scenarios including absent and present APIs, confidence thresholds, and rate limiting.
- Added integration tests for SmartDiff PostgreSQL repositories, covering snapshot storage and retrieval, candidate storage, and material risk change handling.
- Ensured tests validate correct behavior for storing, retrieving, and querying snapshots and candidates, including edge cases and expected outcomes.

 - Create compound unique indexes on (`tenant_id`, `bundle_id`) for catalog; (`tenant_id`, `bundle_id`, `path`) for items.
 - Enforce RLS by always scoping queries to `tenant_id` and validating it at repository boundary (as done in in-memory reference impl).
 - Keep paths lowercased or use ordinal comparisons to avoid locale drift; sort before persistence to preserve determinism.

@@ -0,0 +1,433 @@
+Here’s a clean way to **measure and report scanner accuracy without letting one metric hide weaknesses**: track precision/recall (and AUC) separately for three evidence tiers: **Imported**, **Executed**, and **Tainted→Sink**. This mirrors how risk truly escalates in Python/JS‑style ecosystems.
+
+### Why tiers?
+
+* **Imported**: vuln in a dep that’s present (lots of noise).
+* **Executed**: code/deps actually run on typical paths (fewer FPs).
+* **Tainted→Sink**: user‑controlled data reaches a sensitive sink (highest signal).
+
+### Minimal spec to implement now
+
+**Ground‑truth corpus design**
+
+* Label each finding as: `tier ∈ {imported, executed, tainted_sink}`, `true_label ∈ {TP,FN}`; store model confidence `p∈[0,1]`.
+* Keep language tags (py, js, ts), package manager, and scenario (web API, cli, job).
+
+**DB schema (add to test analytics db)**
+
+* `gt_sample(id, repo, commit, lang, scenario)`
+* `gt_finding(id, sample_id, vuln_id, tier, truth, score, rule, scanner_version, created_at)`
+* `gt_split(sample_id, split ∈ {train,dev,test})`
+
+**Metrics to publish (all stratified by tier)**
+
+* Precision@K (e.g., top‑100), Recall@K
+* PR‑AUC, ROC‑AUC (only if calibrated)
+* Latency p50/p95 from “scan start → first evidence”
+* Coverage: % of samples with any signal in that tier
+
+**Reporting layout (one chart per tier)**
+
+* PR curve + table: `Precision, Recall, F1, PR‑AUC, N(findings), N(samples)`
+* Error buckets: top 5 false‑positive rules, top 5 false‑negative patterns
+
+**Evaluation protocol**
+
+1. Freeze a **toy but diverse corpus** (50–200 repos) with deterministic fixture data and replay scripts.
+2. For each release candidate:
+
+   * Run scanner with fixed flags and feeds.
+   * Emit per‑finding scores; map each to a tier with your reachability engine.
+   * Join to ground truth; compute metrics **per tier** and **overall**.
+3. Fail the build if any of:
+
+   * PR‑AUC(imported) drops >2%, or PR‑AUC(executed/tainted_sink) drops >1%.
+   * FP rate in `tainted_sink` > 5% at operating point Recall ≥ 0.7.
+
+**How to classify tiers (deterministic rules)**
+
+* `imported`: package appears in lockfile/SBOM and is reachable in graph.
+* `executed`: function/module reached by dynamic trace, coverage, or proven path in static call graph used by entrypoints.
+* `tainted_sink`: taint source → sanitizers → sink path proven, with sink taxonomy (eval, exec, SQL, SSRF, deserialization, XXE, command, path traversal).
+
+**Developer checklist (Stella Ops naming)**
+
+* Scanner.Worker: emit `evidence_tier` and `score` on each finding.
+* Excititor (VEX): include `tier` in statements; allow policy per‑tier thresholds.
+* Concelier (feeds): tag advisories with sink classes when available to help tier mapping.
+* Scheduler/Notify: gate alerts on **tiered** thresholds (e.g., page only on `tainted_sink` at Recall‑target op‑point).
+* Router dashboards: three small PR curves + trend sparklines; hover shows last 5 FP causes.
+
+**Quick JSON result shape**
+
+```json
+{
+  "finding_id": "…",
+  "vuln_id": "CVE-2024-12345",
+  "rule": "py.sql.injection.param_concat",
+  "evidence_tier": "tainted_sink",
+  "score": 0.87,
+  "reachability": { "entrypoint": "app.py:main", "path_len": 5, "sanitizers": ["escape_sql"] }
+}
+```
+
+**Operational point selection**
+
+* Choose op‑points per tier by maximizing F1 or fixing Recall targets:
+
+  * imported: Recall 0.60
+  * executed: Recall 0.70
+  * tainted_sink: Recall 0.80
+    Then record **per‑tier precision at those recalls** each release.
+
+**Why this prevents metric gaming**
+
+* A model can’t inflate “overall precision” by over‑penalizing noisy imported findings: you still have to show gains in **executed** and **tainted_sink** curves, where it matters.
+
+If you want, I can draft a tiny sample corpus template (folders + labels) and a one‑file evaluator that outputs the three PR curves and a markdown summary ready for your CI artifact.
+What you are trying to solve is this:
+
+If you measure “scanner accuracy” as one overall precision/recall number, you can *accidentally* optimize the wrong thing. A scanner can look “better” by getting quieter on the easy/noisy tier (dependencies merely present) while getting worse on the tier that actually matters (user-data reaching a dangerous sink). Tiered accuracy prevents that failure mode and gives you a clean product contract:
+
+* **Imported** = “it exists in the artifact” (high volume, high noise)
+* **Executed** = “it actually runs on real entrypoints” (materially more useful)
+* **Tainted→Sink** = “user-controlled input reaches a sensitive sink” (highest signal, most actionable)
+
+This is not just analytics. It drives:
+
+* alerting (page only on tainted→sink),
+* UX (show the *reason* a vuln matters),
+* policy/lattice merges (VEX decisions should not collapse tiers),
+* engineering priorities (don’t let “imported” improvements hide “tainted→sink” regressions).
+
+Below is a concrete StellaOps implementation plan (aligned to your architecture rules: **lattice algorithms run in `scanner.webservice`**, Concelier/Excititor **preserve prune source**, Postgres is SoR, Valkey only ephemeral).
+
+---
+
+## 1) Product contract: what “tier” means in StellaOps
+
+### 1.1 Tier assignment rule (single source of truth)
+
+**Owner:** `StellaOps.Scanner.WebService`
+**Input:** raw findings + evidence objects from workers (deps, callgraph, trace, taint paths)
+**Output:** `evidence_tier` on each normalized finding (plus an evidence summary)
+
+**Tier precedence (highest wins):**
+
+1. `tainted_sink`
+2. `executed`
+3. `imported`
+
+**Deterministic mapping rule:**
+
+* `imported` if SBOM/lockfile indicates package/component present AND vuln applies to that component.
+* `executed` if reachability engine can prove reachable from declared entrypoints (static) OR runtime trace/coverage proves execution.
+* `tainted_sink` if taint engine proves source→(optional sanitizer)→sink path with sink taxonomy.
+
+### 1.2 Evidence objects (the “why”)
+
+Workers emit *evidence primitives*; webservice merges + tiers them:
+
+* `DependencyEvidence { purl, version, lockfile_path }`
+* `ReachabilityEvidence { entrypoint, call_path[], confidence }`
+* `TaintEvidence { source, sink, sanitizers[], dataflow_path[], confidence }`
+
+---
+
+## 2) Data model in Postgres (system of record)
+
+Create a dedicated schema `eval` for ground truth + computed metrics (keeps it separate from production scans but queryable by the UI).
+
+### 2.1 Tables (minimal but complete)
+
+```sql

+  latency_p95_ms int not null,
+  n_expected int not null,
+  n_observed int not null,
+  primary key (eval_run_id, tier, op_point)
+);
+```
+
+### 2.2 Canonical vuln key (avoid mismatches)
+
+Define a single canonical key for matching expected↔observed:
+
+* For dependency vulns: `purl + advisory_id` (or `purl + cve` if available).
+* For code-pattern vulns: `rule_family + stable fingerprint` (e.g., `sink_class + file + normalized AST span`).
+
+You need this to stop “matching hell” from destroying the usefulness of metrics.

+
+---
+
+## 4) Pipeline changes in StellaOps (where code changes go)
+
+### 4.1 Scanner workers: emit evidence primitives (no tiering here)
+
+**Modules:**
+
+* `StellaOps.Scanner.Worker.DotNet`
+* `StellaOps.Scanner.Worker.Python`
+* `StellaOps.Scanner.Worker.Node`
+* `StellaOps.Scanner.Worker.Java`
+
+**Change:**
+
+* Every raw finding must include:
+
+  * `vuln_key`
+  * `rule_key`
+  * `score` (even if coarse at first)
+  * `evidence[]` primitives (dependency / reachability / taint as available)
+  * `first_signal_ms` (time from scan start to first evidence emitted for that finding)
+
+Workers do **not** decide tiers. They only report what they saw.
+
+### 4.2 Scanner webservice: tiering + lattice merge (this is the policy brain)
+
+**Module:** `StellaOps.Scanner.WebService`
+
+Responsibilities:
+
+* Merge evidence for the same `vuln_key` across analyzers.
+* Run reachability/taint algorithms (your lattice policy engine sits here).
+* Assign `evidence_tier` deterministically.
+* Persist normalized findings (production tables) + export to eval capture.
+
+### 4.3 Concelier + Excititor (preserve prune source)
+
+* Concelier stores advisory data; does not “tier” anything.
+* Excititor stores VEX statements; when it references a finding, it may *annotate* tier context, but it must preserve pruning provenance and not recompute tiers.
+
+---
+
+## 5) Evaluator implementation (the thing that computes tiered precision/recall)
+
+### 5.1 New service/tooling
+
+Create:
+
+* `StellaOps.Scanner.Evaluation.Core` (library)
+* `StellaOps.Scanner.Evaluation.Cli` (dotnet tool)
+
+CLI responsibilities:
+
+1. Load corpus samples + expected findings into `eval.sample` / `eval.expected_finding`.
+2. Trigger scans (via Scheduler or direct Scanner API) using `replay-manifest.yml`.
+3. Capture observed findings into `eval.observed_finding`.
+4. Compute per-tier PR curve + PR-AUC + operating-point precision/recall.
+5. Write `eval.metrics` + produce Markdown/JSON artifacts for CI.
+
+### 5.2 Matching algorithm (practical and robust)
+
+For each `sample_id`:
+
+* Group expected by `(vuln_key, tier)`.
+* Group observed by `(vuln_key, tier)`.
+* A match is “same vuln_key, same tier”.
+
+  * (Later enhancement: allow “higher tier” observed to satisfy a lower-tier expected only if you explicitly want that; default: **exact tier match** so you catch tier regressions.)
+
+Compute:
+
+* TP/FP/FN per tier.
+* PR curve by sweeping threshold over observed scores.
+* `first_signal_ms` percentiles per tier.
+
+### 5.3 Operating points (so it’s not academic)
+
+Pick tier-specific gates:
+
+* `tainted_sink`: require Recall ≥ 0.80, minimize FP
+* `executed`: require Recall ≥ 0.70
+* `imported`: require Recall ≥ 0.60
+
+Store the chosen threshold per tier per version (so you can compare apples-to-apples in regressions).
+
+---
+
+## 6) CI gating (how this becomes “real” engineering pressure)
+
+In GitLab/Gitea pipeline:
+
+1. Build scanner + webservice.
+2. Pull pinned concelier snapshot bundle (or local snapshot).
+3. Run evaluator CLI against corpus.
+4. Fail build if:
+
+   * `PR-AUC(tainted_sink)` drops > 1% vs baseline
+   * or precision at `Recall>=0.80` drops below a floor (e.g. 0.95)
+   * or `latency_p95_ms(tainted_sink)` regresses beyond a budget
+
+Store baselines in repo (`/corpus/baselines/<scanner_version>.json`) to make diffs explicit.
+
+---
+
+## 7) UI and alerting (so tiering changes behavior)
+
+### 7.1 UI
+
+Add three KPI cards:
+
+* Imported PR-AUC trend
+* Executed PR-AUC trend
+* Tainted→Sink PR-AUC trend
+
+In the findings list:
+
+* show tier badge
+* default sort: `tainted_sink` then `executed` then `imported`
+* clicking a finding shows evidence summary (entrypoint, path length, sink class)
+
+### 7.2 Notify policy
+
+Default policy:
+
+* Page/urgent only on `tainted_sink` above a confidence threshold.
+* Create ticket on `executed`.
+* Batch report on `imported`.
+
+This is the main “why”: the system stops screaming about irrelevant imports.
+
+---
+
+## 8) Rollout plan (phased, developer-friendly)
+
+### Phase 0: Contracts (1–2 days)
+
+* Define `vuln_key`, `rule_key`, evidence DTOs, tier enum.
+* Add schema `eval.*`.
+
+**Done when:** scanner output can carry evidence + score; eval tables exist.
+
+### Phase 1: Evidence emission + tiering (1–2 sprints)
+
+* Workers emit evidence primitives.
+* Webservice assigns tier using deterministic precedence.
+
+**Done when:** every finding has a tier + evidence summary.
+
+### Phase 2: Corpus + evaluator (1 sprint)
+
+* Build 30–50 samples (10 per tier minimum).
+* Implement evaluator CLI + metrics persistence.
+
+**Done when:** CI can compute tiered metrics and output markdown report.
+
+### Phase 3: Gates + UX (1 sprint)
+
+* Add CI regression gates.
+* Add UI tier badge + dashboards.
+* Add Notify tier-based routing.
+
+**Done when:** a regression in tainted→sink breaks CI even if imported improves.
+
+### Phase 4: Scale corpus + harden matching (ongoing)
+
+* Expand to 200+ samples, multi-language.
+* Add fingerprinting for code vulns to avoid brittle file/line matching.
+
+---
+
+## Definition of “success” (so nobody bikesheds)
+
+* You can point to one release where **overall precision stayed flat** but **tainted→sink PR-AUC improved**, and CI proves you didn’t “cheat” by just silencing imported findings.
+* On-call noise drops because paging is tier-gated.
+* TTFS p95 for tainted→sink stays within a budget you set (e.g., <30s on corpus and <N seconds on real images).
+
+If you want, I can also give you:
+
+* a concrete DTO set (`FindingEnvelope`, `EvidenceUnion`, etc.) in C#/.NET 10,
+* and a skeleton `StellaOps.Scanner.Evaluation.Cli` command layout (`import-corpus`, `run`, `compute`, `report`) that your agents can start coding immediately.

+I’m sharing this because integrating **real‑world exploit likelihood into your vulnerability workflow sharpens triage decisions far beyond static severity alone.**
+
+EPSS (Exploit Prediction Scoring System) is a **probabilistic model** that estimates the *likelihood* a given CVE will be exploited in the wild over the next ~30 days, producing a score from **0 to 1** you can treat as a live probability. ([FIRST][1])
+

+
+• **CVSS v4** gives you a deterministic measurement of *severity* (impact + exploitability traits) on a 0–10 scale. ([Wikipedia][2])
+• **EPSS** gives you a dynamic, **data‑driven probability of exploitation** (0–1) updated as threat data flows in. ([FIRST][3])
+
+Because CVSS doesn’t reflect *actual threat activity*, combining it with EPSS lets you identify vulnerabilities that are *both serious and likely to be exploited* — rather than just theoretically dangerous. ([Intruder][4])
+
+For automated platforms (like Stella Ops), treating **EPSS updates as event triggers** makes sense: fresh exploit probability changes can drive workflows such as scheduler alerts, notifications, and enrichment of vulnerability records — giving your pipeline *live risk context* to act on. (Industry best practice is to feed EPSS into prioritization alongside severity and threat intelligence.) ([Microsoft Tech Community][5])
+
+If you build your triage chain around **probabilistic trust ranges rather than static buckets**, you reduce noise and focus effort where attackers are most likely to strike next.

+To build an **EPSS database from first principles**, think of it as a **time-series enrichment layer over CVEs**, not a standalone vulnerability catalog. EPSS does not replace CVE/NVD; it annotates it with *probabilistic exploit likelihood* that changes daily.
+
+Below is a **clean, production-grade blueprint**, aligned with how Stella Ops should treat it.
+
+---
+
+## 1. What EPSS actually gives you (ground truth)
+
+EPSS is published by FIRST as **daily snapshots**, not events.
+
+Each record is essentially:
+
+* `cve_id`
+* `epss_score` (0.00000–1.00000)
+* `percentile` (rank vs all CVEs)
+* `date` (model run date)
+
+No descriptions, no severity, no metadata.
+
+**Key implication:**
+Your EPSS database must be **append-only time-series**, not “latest-only”.
+
+---
+
+## 2. Authoritative data source
+
+FIRST publishes **two canonical feeds**:
+
+1. **Daily CSV** (full snapshot, ~200k CVEs)
+2. **Daily JSON** (same content, heavier)
+
+Best practice:
+
+* Use **CSV for bulk ingestion**
+* Use **JSON only for debugging or spot checks**
+
+You do **not** train EPSS yourself unless you want to replicate FIRST’s ML pipeline (not recommended).
+
+---
+
+## 3. Minimal EPSS schema (PostgreSQL-first)
+
+### Core table (append-only)
+
+```sql
+CREATE TABLE epss_scores (
+    cve_id           TEXT NOT NULL,
+    score            DOUBLE PRECISION NOT NULL,
+    percentile       DOUBLE PRECISION NOT NULL,
+    model_date       DATE NOT NULL,
+    ingested_at      TIMESTAMPTZ NOT NULL DEFAULT now(),
+    PRIMARY KEY (cve_id, model_date)
+);
+```
+
+### Indexes that matter
+
+```sql
+CREATE INDEX idx_epss_date ON epss_scores (model_date);
+CREATE INDEX idx_epss_score ON epss_scores (score DESC);
+CREATE INDEX idx_epss_cve_latest
+  ON epss_scores (cve_id, model_date DESC);
+```
+
+---
+
+## 4. “Latest view” (never store latest as truth)
+
+Create a **deterministic view**, not a table:
+
+```sql
+CREATE VIEW epss_latest AS
+SELECT DISTINCT ON (cve_id)
+    cve_id,
+    score,
+    percentile,
+    model_date
+FROM epss_scores
+ORDER BY cve_id, model_date DESC;
+```
+
+This preserves:
+
+* Auditability
+* Replayability
+* Backtesting
+
+---
+
+## 5. Ingestion pipeline (daily, deterministic)
+
+### Step-by-step
+
+1. **Scheduler triggers daily EPSS fetch**
+2. Download CSV for `YYYY-MM-DD`
+3. Validate:
+
+   * row count sanity
+   * score ∈ [0,1]
+   * monotonic percentile
+4. Bulk insert with `COPY`
+5. Emit **“epss.updated” event**
+
+### Failure handling
+
+* If feed missing → **no delete**
+* If partial → **reject entire day**
+* If duplicate day → **idempotent ignore**
+
+---
+
+## 6. Event model inside Stella Ops
+
+Treat EPSS as **risk signal**, not vulnerability data.
+
+### Event emitted
+
+```json
+{
+  "event": "epss.updated",
+  "model_date": "2025-12-16",
+  "cve_count": 231417,
+  "delta_summary": {
+    "new_high_risk": 312,
+    "significant_jumps": 87
+  }
+}
+```
+
+---
+
+## 7. How EPSS propagates in Stella Ops
+
+**Correct chain (your architecture):**
+
+```
+Scheduler
+  → EPSS Ingest Worker
+    → Notify
+      → Concealer
+        → Excititor
+```
+
+### What happens downstream
+
+* **Concelier**
+
+  * Enrich existing vulnerability facts
+  * Never overwrite CVSS or VEX
+* **Excititor**
+
+  * Re-evaluate policy thresholds
+  * Trigger alerts only if:
+
+    * EPSS crosses trust boundary
+    * OR delta > configured threshold
+
+---
+
+## 8. Trust-lattice integration (important)
+
+Do **not** treat EPSS as severity.
+
+Correct interpretation:
+
+| Signal          | Nature               |
+| --------------- | -------------------- |
+| CVSS v4         | Deterministic impact |
+| EPSS            | Probabilistic threat |
+| VEX             | Vendor intent        |
+| Runtime context | Actual exposure      |
+
+**Rule:**
+EPSS only *modulates confidence*, never asserts truth.
+
+Example lattice rule:
+
+```
+IF CVSS >= 8.0
+AND EPSS >= 0.35
+AND runtime_exposed = true
+→ elevate to “Immediate Attention”
+```
+
+---
+
+## 9. Retention policy
+
+Recommended:
+
+* Keep **all EPSS history** (storage is cheap)
+* Allow optional roll-up:
+
+  * weekly averages
+  * max-delta windows
+
+Never delete raw data.
+
+---
+
+## 10. What not to do (common mistakes)
+
+* ❌ Storing only latest EPSS
+* ❌ Mixing EPSS into CVE table
+* ❌ Treating EPSS as severity
+* ❌ Triggering alerts on every daily fluctuation
+* ❌ Recomputing EPSS internally
+
+---
+
+## 11. Minimal MVP checklist
+
+* [x] Append-only table
+* [x] Latest view
+* [x] Daily scheduler job
+* [x] Delta detection
+* [x] Event emission
+* [x] Policy-driven alerting
+
+---
+
+### Bottom line
+
+An EPSS database is **not a vulnerability database**.
+It is a **probabilistic signal ledger** that feeds your trust calculus.
+
+If you want, next I can:
+
+* Provide **.NET ingestion code**
+* Design **delta-based alert thresholds**
+* Map EPSS → **Trust Algebra Studio** rules
+* Show how to **replay historical EPSS for audits**
+Below is a **full implementation + usage plan** for **EPSS v4 (published starting 2025-03-17)** in Stella Ops, designed for your existing components (**Scheduler WebService**, **Notify WebService**, **Concelier**, **Excititor**, **Scanner.WebService**) and consistent with your architectural rules (Postgres system of record; Valkey optional ephemeral accelerator; lattice logic stays in Scanner.WebService).
+
+EPSS facts you should treat as authoritative:
+
+* EPSS is a **daily** probability score in **[0..1]** with a **percentile**, per CVE. ([first.org][1])
+* FIRST provides **daily CSV .gz snapshots** at `https://epss.empiricalsecurity.com/epss_scores-YYYY-mm-dd.csv.gz`. ([first.org][1])
+* FIRST also provides a REST API base `https://api.first.org/data/v1/epss` with filters and `scope=time-series`. ([first.org][2])
+* The daily files include (at least since v2) a leading `#` comment with **model version + publish date**, and FIRST explicitly notes the v4 publishing start date. ([first.org][1])
+
+---
+
+## 1) Product scope (what Stella Ops must deliver)
+
+### 1.1 Functional capabilities
+
+1. **Ingest EPSS daily snapshot** (online) + **manual import** (air-gapped bundle).
+2. Store **immutable history** (time series) and maintain a **fast “current projection”**.
+3. Enrich:
+
+   * **New scans** (attach EPSS at scan time as immutable evidence).
+   * **Existing findings** (attach latest EPSS for “live triage” without breaking replay).
+4. Trigger downstream events:
+
+   * `epss.updated` (daily)
+   * `vuln.priority.changed` (only when band/threshold changes)
+5. UI/UX:
+
+   * Show EPSS score + percentile + trend (delta).
+   * Filters and sort by exploit likelihood and changes.
+6. Policy hooks (but **calculation lives in Scanner.WebService**):
+
+   * Risk priority uses EPSS as a probabilistic factor, not “severity”.
+
+### 1.2 Non-functional requirements
+
+* **Deterministic replay**: every scan stores the EPSS snapshot reference used (model_date + import_run_id + hash).
+* **Idempotent ingestion**: safe to re-run for same date.
+* **Performance**: daily ingest of ~300k rows should be seconds-to-low-minutes; query path must be fast.
+* **Auditability**: retain raw provenance: source URL, hashes, model version tag.
+* **Deployment profiles**:
+
+  * Default: Postgres + Valkey (optional)
+  * Air-gapped minimal: Postgres only (manual import)
+
+---
+
+## 2) Data architecture (Postgres as source of truth)
+
+### 2.1 Tables (recommended minimum set)
+
+#### A) Import runs (provenance)
+
+```sql
+CREATE TABLE epss_import_runs (
+  import_run_id      UUID PRIMARY KEY,
+  model_date         DATE NOT NULL,
+  source_uri         TEXT NOT NULL,
+  retrieved_at       TIMESTAMPTZ NOT NULL,
+  file_sha256        TEXT NOT NULL,
+  decompressed_sha256 TEXT NULL,
+  row_count          INT NOT NULL,
+  model_version_tag  TEXT NULL,      -- e.g. v2025.03.14 (from leading # comment)
+  published_date     DATE NULL,      -- from leading # comment if present
+  status             TEXT NOT NULL,  -- SUCCEEDED / FAILED
+  error              TEXT NULL,
+  UNIQUE (model_date)
+);
+```
+
+#### B) Immutable daily scores (time series)
+
+Partition by month (recommended):
+
+```sql
+CREATE TABLE epss_scores (
+  model_date   DATE NOT NULL,
+  cve_id       TEXT NOT NULL,
+  epss_score   DOUBLE PRECISION NOT NULL,
+  percentile   DOUBLE PRECISION NOT NULL,
+  import_run_id UUID NOT NULL REFERENCES epss_import_runs(import_run_id),
+  PRIMARY KEY (model_date, cve_id)
+) PARTITION BY RANGE (model_date);
+```
+
+Create monthly partitions via migration helper.
+
+#### C) Current projection (fast lookup)
+
+```sql
+CREATE TABLE epss_current (
+  cve_id      TEXT PRIMARY KEY,
+  epss_score  DOUBLE PRECISION NOT NULL,
+  percentile  DOUBLE PRECISION NOT NULL,
+  model_date  DATE NOT NULL,
+  import_run_id UUID NOT NULL
+);
+
+CREATE INDEX idx_epss_current_score_desc ON epss_current (epss_score DESC);
+CREATE INDEX idx_epss_current_percentile_desc ON epss_current (percentile DESC);
+```
+
+#### D) Changes (delta) to drive enrichment + notifications
+
+```sql
+CREATE TABLE epss_changes (
+  model_date     DATE NOT NULL,
+  cve_id         TEXT NOT NULL,
+  old_score      DOUBLE PRECISION NULL,
+  new_score      DOUBLE PRECISION NOT NULL,
+  delta_score    DOUBLE PRECISION NULL,
+  old_percentile DOUBLE PRECISION NULL,
+  new_percentile DOUBLE PRECISION NOT NULL,
+  flags          INT NOT NULL, -- bitmask: NEW_SCORED, CROSSED_HIGH, BIG_JUMP, etc
+  PRIMARY KEY (model_date, cve_id)
+) PARTITION BY RANGE (model_date);
+```
+
+### 2.2 Why “current projection” is necessary
+
+EPSS is daily; your scan/UI paths need **O(1) latest lookup**. Keeping `epss_current` avoids expensive “latest per cve” queries across huge time-series.
+
+---
+
+## 3) Service responsibilities and event flow
+
+### 3.1 Scheduler.WebService (or Scheduler.Worker)
+
+* Owns the **schedule**: daily EPSS import job.
+* Emits a durable job command (Postgres outbox) to Concelier worker.
+
+Job types:
+
+* `epss.ingest(date=YYYY-MM-DD, source=online|bundle)`
+* `epss.backfill(date_from, date_to)` (optional)
+
+### 3.2 Concelier (ingestion + enrichment, “preserve/prune source” compliant)
+
+Concelier does **not** compute lattice/risk. It:
+
+* Downloads/imports EPSS snapshot.
+* Stores raw facts + provenance.
+* Computes **delta** for changed CVEs.
+* Updates `epss_current`.
+* Triggers downstream enrichment jobs for impacted vulnerability instances.
+
+Produces outbox events:
+
+* `epss.updated` (always after successful ingest)
+* `epss.failed` (on failure)
+* `vuln.priority.changed` (after enrichment, only when a band changes)
+
+### 3.3 Scanner.WebService (risk evaluation lives here)
+
+On scan:
+
+* pulls `epss_current` for the CVEs in the scan (bulk query).
+* stores immutable evidence:
+
+  * `epss_score_at_scan`
+  * `epss_percentile_at_scan`
+  * `epss_model_date_at_scan`
+  * `epss_import_run_id_at_scan`
+* computes *derived* risk (your lattice/scoring) using EPSS as an input factor.
+
+### 3.4 Notify.WebService
+
+Subscribes to:
+
+* `epss.updated`
+* `vuln.priority.changed`
+* sends:
+
+  * Slack/email/webhook/in-app notifications (your channels)
+
+### 3.5 Excititor (VEX workflow assist)
+
+EPSS does not change VEX truth. Excititor may:
+
+* create a “**VEX requested / vendor attention**” task when:
+
+  * EPSS is high AND vulnerability affects shipped artifact AND VEX missing/unknown
+    No lattice math here; only task generation.
+
+---
+
+## 4) Ingestion design (online + air-gapped)
+
+### 4.1 Preferred source: daily CSV snapshot
+
+Use FIRST’s documented daily snapshot URL pattern. ([first.org][1])
+
+Pipeline for date D:
+
+1. Download `epss_scores-D.csv.gz`.
+2. Decompress stream.
+3. Parse:
+
+   * Skip leading `# ...` comment line; capture model tag and publish date if present. ([first.org][1])
+   * Parse CSV header fields `cve, epss, percentile`. ([first.org][1])
+4. Bulk load into **TEMP staging**.
+5. In one DB transaction:
+
+   * insert `epss_import_runs`
+   * insert into partition `epss_scores`
+   * compute `epss_changes` by comparing staging vs `epss_current`
+   * upsert `epss_current`
+   * enqueue outbox `epss.updated`
+6. Commit.
+
+### 4.2 Air-gapped bundle import
+
+Accept a local file + manifest:
+
+* `epss_scores-YYYY-mm-dd.csv.gz`
+* `manifest.json` containing: sha256, source attribution, retrieval timestamp, optional DSSE signature.
+
+Concelier runs the same ingest pipeline, but source_uri becomes `bundle://…`.
+
+---
+
+## 5) Enrichment rules (existing + new scans) without breaking determinism
+
+### 5.1 New scan findings (immutable)
+
+Store EPSS “as-of” scan time:
+
+* This supports replay audits even if EPSS changes later.
+
+### 5.2 Existing findings (live triage)
+
+Maintain a mutable “current EPSS” on vulnerability instances (or a join at query time):
+
+* Concelier updates only the **triage projection**, never the immutable scan evidence.
+
+Recommended pattern:
+
+* `scan_finding_evidence` → immutable EPSS-at-scan
+* `vuln_instance_triage` (or columns on instance) → current EPSS + band
+
+### 5.3 Efficient targeting using epss_changes
+
+On `epss.updated(D)` Concelier:
+
+1. Reads `epss_changes` for D where flags indicate “material change”.
+2. Finds impacted vulnerability instances by CVE.
+3. Updates only those.
+4. Emits `vuln.priority.changed` only if band/threshold crossed.
+
+---
+
+## 6) Notification policy (defaults you can ship)
+
+Define configurable thresholds:
+
+* `HighPercentile = 0.95` (top 5%)
+* `HighScore = 0.50` (probability threshold)
+* `BigJumpDelta = 0.10` (meaningful daily change)
+
+Notification triggers:
+
+1. **Newly scored** CVE appears in your inventory AND `percentile >= HighPercentile`
+2. Existing CVE in inventory **crosses above** HighPercentile or HighScore
+3. Delta jump above BigJumpDelta AND CVE is present in runtime-exposed assets
+
+All thresholds must be org-configurable.
+
+---
+
+## 7) API + UI surfaces
+
+### 7.1 Internal API (your services)
+
+Endpoints (example):
+
+* `GET /epss/current?cve=CVE-…&cve=CVE-…`
+* `GET /epss/history?cve=CVE-…&days=180`
+* `GET /epss/top?order=epss&limit=100`
+* `GET /epss/changes?date=YYYY-MM-DD&flags=…`
+
+### 7.2 UI requirements
+
+For each vulnerability instance:
+
+* EPSS score + percentile
+* Model date
+* Trend: delta vs previous scan date or vs yesterday
+* Filter chips:
+
+  * “High EPSS”
+  * “Rising EPSS”
+  * “High CVSS + High EPSS”
+* Evidence panel:
+
+  * shows EPSS-at-scan and current EPSS side-by-side
+
+Add attribution footer in UI per FIRST usage expectations. ([first.org][3])
+
+---
+
+## 8) Reference implementation skeleton (.NET 10)
+
+### 8.1 Concelier Worker: `EpssIngestJob`
+
+Core steps (streamed, low memory):
+
+* `HttpClient` → download `.gz`
+* `GZipStream` → `StreamReader`
+* parse comment line `# …`
+* parse CSV rows and `COPY` into TEMP table using `NpgsqlBinaryImporter`
+
+Pseudo-structure:
+
+* `IEpssSource` (online vs bundle)
+* `EpssCsvStreamParser` (yields rows)
+* `EpssRepository.IngestAsync(modelDate, rows, header, hashes, ct)`
+* `OutboxPublisher.EnqueueAsync(new EpssUpdatedEvent(...))`
+
+### 8.2 Scanner.WebService: `IEpssProvider`
+
+* `GetCurrentAsync(IEnumerable<string> cves)`:
+
+  * single SQL call: `SELECT ... FROM epss_current WHERE cve_id = ANY(@cves)`
+* optional Valkey cache:
+
+  * only as a read-through cache; never required for correctness.
+
+---
+
+## 9) Test plan (must be implemented, not optional)
+
+### 9.1 Unit tests
+
+* CSV parsing:
+
+  * handles leading `#` comment
+  * handles missing/extra whitespace
+  * rejects invalid scores outside [0,1]
+* delta flags:
+
+  * new-scored
+  * crossing thresholds
+  * big jump
+
+### 9.2 Integration tests (Testcontainers)
+
+* ingest a small `.csv.gz` fixture into Postgres
+* verify:
+
+  * epss_import_runs inserted
+  * epss_scores inserted (partition correct)
+  * epss_current upserted
+  * epss_changes correct
+  * outbox has `epss.updated`
+
+### 9.3 Performance tests
+
+* ingest synthetic 310k rows (close to current scale) ([first.org][1])
+* budgets:
+
+  * parse+copy under defined SLA
+  * peak memory bounded
+* concurrency:
+
+  * ensure two ingests cannot both claim same model_date (unique constraint)
+
+---
+
+## 10) Implementation rollout plan (what your agents should build in order)
+
+1. **DB migrations**: tables + partitions + indexes.
+2. **Concelier ingestion job**: online download + bundle import + provenance + outbox event.
+3. **epss_current + epss_changes projection**: delta computation and flags.
+4. **Scanner.WebService integration**: attach EPSS-at-scan evidence + bulk lookup API.
+5. **Concelier enrichment job**: update triage projections for impacted vuln instances.
+6. **Notify**: subscribe to `vuln.priority.changed` and send notifications.
+7. **UI**: EPSS fields, filters, trend, evidence panel.
+8. **Backfill tool** (optional): last 180 days (or configurable) via daily CSV URLs.
+9. **Ops runbook**: schedules, manual re-run, air-gap import procedure.
+
+---
+
+If you want this to be directly executable by your agents, tell me which repo layout you want to target (paths/module names), and I will convert the above into:
+
+* exact **SQL migration files**,
+* concrete **C# .NET 10 code** for ingestion + repository + outbox,
+* and a **TASKS.md** breakdown with acceptance criteria per component.

+- Working directory: `src/Concelier/**` (WebService, __Libraries, Storage.Postgres, analyzers, tests, seed-data). Do not edit other modules unless explicitly referenced by this sprint.
 - Mission: Link-Not-Merge (LNM) ingestion of advisory observations, correlation into linksets, evidence/export APIs, and deterministic telemetry.

 ## Coding & Observability Standards
 - Target **.NET 10**; prefer latest C# preview features already enabled in repo.
-- Mongo driver ≥ 3.x; canonical BSON/JSON mapping lives in Storage.Mongo.
+- Npgsql driver for PostgreSQL; canonical JSON mapping in Storage.Postgres.
 - Metrics: use `Meter` names under `StellaOps.Concelier.*`; tag `tenant`, `source`, `result` as applicable. Counters/histograms must be documented.
 - Logging: structured, no PII; include `tenant`, `source`, `job`, `correlationId` when available.
 - Scheduler/locks: one lock per connector/export job; no duplicate runs; honor `CancellationToken`.
 
 ## Testing Rules
 - Write/maintain tests alongside code:
-  - Web/API: `StellaOps.Concelier.WebService.Tests` with WebApplicationFactory + Mongo2Go fixtures.
+  - Web/API: `StellaOps.Concelier.WebService.Tests` with WebApplicationFactory + Testcontainers fixtures.
   - Core/Linkset/Guards: `StellaOps.Concelier.Core.Tests`.
-  - Storage: `StellaOps.Concelier.Storage.Mongo.Tests` (use in-memory or Mongo2Go; determinism on ordering/hashes).
+  - Storage: `StellaOps.Concelier.Storage.Postgres.Tests` (use in-memory or Testcontainers; determinism on ordering/hashes).
   - Observability/analyzers: tests in `__Analyzers` or respective test projects.
 - Tests must assert determinism (stable ordering/hashes), tenant guards, AOC invariants, and no derived fields in ingestion.
 - Prefer seeded fixtures under `seed-data/` for repeatability; avoid network in tests.
