7.2 KiB
Raw Permalink Blame History

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.
