Here’s a crisp plan that turns a big strategy into shippable work, with clear KPIs and sequencing so you can schedule sprints instead of debating them.

# Why this matters (quick primer)

You’re building a release‑control plane with evidence‑based security. These five “moats” are concrete assets that compound over time:

* **CSFG:** a graph that fingerprints call stacks to match incidents fast.
* **Marketplace:** curated symbol packs & test harnesses that boost coverage and create network effects.
* **PSDI:** precomputed semantic delta index for sub‑second (or near) binary delta verification.
* **FRVF:** cached “micro‑witnesses” to rapidly re‑verify incidents.
* **FBPE:** federated provenance exchange + usage reputation across vendors.

Below I give: (1) a 6‑sprint MVP plan for **Marketplace + FRVF**, then (2) a 6‑quarter roadmap to phase **CSFG → PSDI → FBPE**. All items come with acceptance criteria you can wire into your CI dashboards.

# 6 sprints (2‑week sprints) → Marketplace + FRVF MVP

**Global MVP exit criteria (after Sprint 6)**

* Marketplace: **≥500 symbol bundles** hosted; **median symbol_lookup_latency ≤ 50 ms**; **contributor_retention ≥ 30%** at 1 quarter; initial licensing flows live.
* FRVF: deterministic micro‑witness capture & sandbox replay with **replay_success_ratio ≥ 0.95** on seeded incidents; **avg verify_time ≤ 30 s** for cached proofs.

### Sprint 1 — Foundations & APIs

* Marketplace

  * Repo layout, contributor manifest spec (symbol pack schema, license tag, checksum).
  * Upload API (signed, size/format validated), storage backend, basic search (by toolchain, arch, version).
* FRVF

  * “Micro‑witness” schema (inputs, seeds, env, toolchain digest, artifact IDs).
  * Deterministic runner scaffold (container/Snap/OCI capsule), seed capture hooks.
    **Demos/KPIs:** 50 internal symbol packs; witness capsule recorded & replayed locally.

### Sprint 2 — Curation & Replay Harness

* Marketplace

  * Maintainer review workflow, reputation seed (download count, maintainer trust score), basic UI.
* FRVF

  * Replay harness v1 (controlled sandbox, resource caps), initial cache layer for verify results.
    **KPIs:** ingest 150 curated packs; **replay_success_ratio ≥ 0.90** on 10 seeded incidents.

### Sprint 3 — Auth, Licensing, & Privacy

* Marketplace

  * Account system (OIDC), EULA/license templates, entitlement checks, signed pack index.
* FRVF

  * Privacy controls (PII scrubbing in logs), redaction policy, provenance pointers (DSSE).
    **KPIs:** 300 packs live; end‑to‑end paid/private pack smoke test; FRVF logs pass redaction checks.

### Sprint 4 — Performance & Observability

* Marketplace

  * Index acceleration (in‑memory key paths), CDN for pack metadata, **p50 lookup ≤ 50 ms**.
* FRVF

  * Cached micro‑witness store; verify pipeline parallelism; per‑incident SLOs & dashboards.
    **KPIs:** p50 lookup ≤ 50 ms; **avg verify_time ≤ 30 s** on cached proofs.

### Sprint 5 — Contributor Flywheel & Incident Bundles

* Marketplace

  * Contributor portal (stats, badges), auto‑compat checks vs toolchains; abuse/gaming guardrails.
* FRVF

  * “Incident bundle” artifact: witness + symbol pointers + minimal replay script; export/import.
    **KPIs:** **≥500 packs** total; 10 external contributors; publish 10 incident bundles.

### Sprint 6 — Hardening & MVP Gate

* Marketplace

  * Billing hooks (plan entitlements), takedown & dispute workflow, audit logs.
* FRVF

  * Determinism checks (variance = 0 across N replays), failure triage UI, limits & quotas.
    **MVP gate:** replay_success_ratio ≥ 0.95; contributor_retention early proxy ≥ 30% (opt‑in waitlist); security review passed.

# 6‑quarter roadmap (18 months) — CSFG → PSDI → FBPE

## Q1: MVP ship & seed customers (Sprints 1‑6 above)

* **Ship Marketplace + FRVF MVP**; start paid pilots for incident‑response retainers.
* Instrument KPI baselines.

## Q2: CSFG foundations (graph + normalizer)

* Build **canonical frame normalizer** (unifies frames across ABIs/optimizations).
* Ingest **1 000 curated traces**; expose **match API** with **median_latency ≤ 200 ms**.
* **Acceptance:** stack_precision ≥ 0.90, stack_recall ≥ 0.85 on seeded corpus.
* **Synergy:** Marketplace boosts symbol_coverage → better CSFG precision.

## Q3: PSDI prototype (delta proofs)

* Normalize IR for **top 10 OSS toolchains** (e.g., GCC/Clang/MSVC/Go/Rust/Java/.NET).
* Generate **delta index**; verify 80% of deltas **≤ 5 s** (p95 ≤ 30 s).
* **Synergy:** FRVF uses PSDI to accelerate verify loops; offer “fast‑patch acceptance” SLA.

## Q4: CSFG + PSDI scale‑out

* CSFG: continuous contribution APIs, enterprise private graphs; privacy/anonymization.
* PSDI: sharding, freshness strategies; client libraries.
* **Commercial:** add paid SLAs for “verified delta” and “stack match coverage”.

## Q5: FBPE federation (seed network)

* Implement **federation protocol**, basic **usage reputation**, private peering with 3 partners.
* **Acceptance:** cross_verify_success_ratio ≥ 0.95; provenance_query p50 ≤ 250 ms.
* **GTM:** joint reference customers, procurement preference for federation members.

## Q6: Federation scale & governance

* Multi‑tenant federation, credits/rewards for contribution, governance & legal guardrails.
* Enterprise private graphs + hardened privacy controls across all moats.
* **North‑star KPIs:** participating_node_growth ≥ 50% QoQ; incident **time‑to‑verify ↓ 60%** vs baseline.

# Roles, squads, and effort bands

* **Squad A (Marketplace + FRVF)** — 1 PM, 1 EM, 4–5 engineers.

  * Effort bands: Marketplace **4–8 eng‑months**, FRVF **4–9 eng‑months**.
* **Research Engine (CSFG + PSDI)** — 1 research‑lead, 3–4 engineers (compilers/IR/graph).

  * CSFG **9–18 eng‑months**, PSDI **6–12 eng‑months**.
* **FBPE** — starts Q5 with 3–4 engineers (protocols, privacy, governance) **6–12 eng‑months**.

---

# Risks & mitigations (short)

* **Symbol/IP licensing disputes** → strict license tags, contributor contracts, takedown SLAs.
* **Poisoning/PII leakage** → validation pipelines, redaction, attestation on submissions.
* **Determinism gaps** → constrained capsules, toolchain snapshotting, seed pinning.
* **Index freshness cost (PSDI)** → tiered sharding + recency heuristics.
* **Federation trust bootstrapping** → start with private peering & reputation primitives.

---

# What to wire into your dashboards (KPI set)

* Marketplace: symbol_coverage_pct uplift (target **≥ 20% in 90 days** for pilots), p50 lookup latency, contributor_retention, dispute rate.
* FRVF: replay_success_ratio, verify_time_ms, deterministic_score_variance.
* CSFG: stack_precision / stack_recall, median_match_latency.
* PSDI: median/p95 delta_proof_verification_time, delta_entropy calibration.
* FBPE: participating_node_growth, cross_verify_success_ratio, provenance_query_latency.

If you want, I can generate the **six sprint tickets** (per sprint: epics → stories → tasks), plus a **lightweight schema pack** (symbol pack manifest, micro‑witness JSON, CSFG frame normalizer rules) ready to drop into your Stella Ops repo structure.
