# INTENT ↔ SCOPE Gap Analysis — Post SAND-WP-0007

**Date:** 2026-06-24  
**Author:** codex  
**Trigger:** SAND-WP-0001–0008 finished; SAND-WP-0007 (snapshots) shipped.
SCOPE.md refreshed 2026-06-24. Prior assessment:
`history/2026-06-23-post-wp0003-intent-scope-gap-analysis.md` (superseded).

## 1. Executive summary

sand-boxer is **v0 feature-complete** for establishment: compose provision,
vm-packer attach, SaaS stub + routing + credits, workspace checkpoints, host
telemetry, and sibling migration arc (wise-validator + the-custodian shim).

Remaining distance to INTENT is **operational hardening** (TTL enforcement —
the largest functional gap), **registry hygiene** (classification + federation),
**reachability depth** (ops-bridge descriptor), and **extension breadth**
(real cloud adapters, Packer orchestration). Host topology (sandboxer01) and
some sibling sign-offs sit outside this repo.

**Vector movement:** `D5/A3/C3/R3` (post-WP-0003) → **`D5/A4/C4/R3`**

| Dimension | Post-WP-0003 | Now (post-WP-0007) | Next target |
| --- | --- | --- | --- |
| Discovery | D5 | **D5** | D6 after registry publish |
| Availability | A3 | **A4** | A5 after TTL + HTTP parity |
| Completeness | C3 | **C4** | C5 after cloud adapters |
| Reliability | R3 | **R3** | R4 after TTL auto-expire |

## 3. INTENT — four pillars (current)

### Pillar 4: Payments and metering

| Capability | INTENT | Status | Gap |
| --- | --- | --- | --- |

## 4. Governing principle scorecard

| # | Question | Status | Evidence / gap |
| --- | --- | --- | --- |
| 1 | Which sandbox recipe? | **Met** | 6 profiles, loader |
| 2 | Which backend? | **Met** | Routing + 3 extensions |
| 3 | Where does it run? | **Partial** | Placement works; sandboxer01 not live |
| 4 | How is isolation enforced? | **Partial** | Compose isolation; **TTL not enforced** |
| 5 | How reachable? | **Partial** | SSH direct; ops-bridge not in descriptor |
| 6 | What happened? | **Met** | State Hub + stores |
| 7 | What did it cost? | **Partial** | Metered stub; no fin-hub export |

**Score: 3 met, 4 partial, 0 not met** (was 2/4/1 post-WP-0003)

## 5. Self-sufficiency and sibling boundaries

| Criterion | Status | Notes |
| --- | --- | --- |
| Operates without wise-validator | **Met** | Full CLI surface |
| wise-validator optional consumer | **Met** | One-way dependency |
| sand-boxer does not validate | **Met** | — |
| the-custodian shim complete | **Met** | SAND-WP-0004 |
| glas-harness / snuggle consumer smoke | **Not met** | Docs only |
| activity-core TTL reap hook | **Not met** | No contract or scheduler |

---

## 6. Maturity target gaps

| wise-validator validation environments | **Met** | `validate run` |
| snuggle-inventor build sandboxes + secret refs | **Not met** | Secret boundary open |
| activity-core bounded venues + visibility | **Partial** | Events yes; TTL reap no |
| Operators route self-hosted vs SaaS spend | **Met** | Routing + credits |
| Workstation optional for runtime | **Met** | Remote compose + shim |

| `capability.execution.sandbox-provision` maturity | **Stale** | Still cites WP-0002 in-progress |
| `reuse-surface validate` publish | **Not run** | Federation blocked |
| Security runbook (blast-radius honesty) | **Absent** | INTENT design principle undocumented |

---

## 8. Remaining gaps (prioritized)

| Prio | Gap | Owner | Proposed track |
| --- | --- | --- | --- |
| ~~**P1**~~ | TTL enforcement + `extend_ttl` + `expires_at` | sand-boxer | **SAND-WP-0009** — done |
| ~~**P2**~~ | TTL reap / activity-core contract | sand-boxer | **SAND-WP-0009** — `docs/integrations/activity-core.md` |
| ~~**P3**~~ | `.repo-classification.yaml` + registry refresh | sand-boxer | **SAND-WP-0009** — done |
| ~~**P4**~~ | HTTP API parity (`recreate`, `extend_ttl`) | sand-boxer | **SAND-WP-0009** — done |
| **P5** | Real E2B / Modal adapters + BYOK | sand-boxer | **SAND-WP-0010** |
| **P6** | ops-bridge tunnel in reachability descriptor | sand-boxer | **SAND-WP-0011** |
| **P7** | Consumer profiles (glas-harness, snuggle) | sand-boxer | **SAND-WP-0011** |
| **P8** | Packer build orchestration + remote-build shim | sand-boxer | **SAND-WP-0012** |
| **P9** | Cross-host snapshot transfer | sand-boxer | Future |
| **P10** | fin-hub billing export | sand-boxer + platform | With SAND-WP-0010 |
| **P11** | sandboxer01 dedicated host | infra / operator | Outside repo |
| **P12** | wise-validator remote smoke (T09) | wise-validator | Operator |

## 9. Recommended workplans (2026-06-24)

| Workplan | Status | Closes |
| --- | --- | --- |
| SAND-WP-0009 | **finished** | P1–P4 (TTL, hygiene, HTTP parity) |
| SAND-WP-0010 | ready | P5, P10 (E2B/Modal, BYOK, fin-hub) |
| SAND-WP-0011 | ready | P6, P7 (reachability, consumer profiles) |
| SAND-WP-0012 | ready | P8 (Packer orchestration, remote-build shim) |

**Suggested implementation order:** 0010 and 0011 may parallelize; 0012 depends
on stable vm-packer attach (done). Operator tracks P11/P12 outside repo.
