Sprint 14 Closeout + Sprint 15 Scope

Date: 2026-03-05 Status: Approved

Context

Sprint 14 opened with four epics: regulatory-safe verifiable state architecture (compliance), IPv6 dual-stack transport, pilot Flow C completion, and service-discovery hardening.

By 2026-03-05 the compliance foundation is further along than the sprint file reflects:

PR #1322 (fix/icn-core-backup-restore-provenance) is open and fixing call-site fallout from the ProvenanceRef migration — merge this as hygiene before starting new compliance work.

Design Decision: "No New Conceptual Surfaces" Rule

Sprint 14 is locked to a pilot truth + regulatory spine bundle. Nothing that opens a new conceptual surface (new type model, new semantic layer) ships in S14 unless it is on the critical path to Flow C or ExecutionReceiptGate.

This rule eliminates:

• t4 (auth semantics) — hardening, not critical path
• t12 (CCL credit formula) — semantics-heavy; high debate risk
• t14 (timestamp cleanup) — pure cleanup
• t8/t9/t18 (IPv6 type refactor) — structural; would expand to eat the sprint

Sprint 14 — Final Scope

Anchor: Flow C demo runs end-to-end. ExecutionReceiptGate enforces governance→execution linkage. Gateway listens on IPv6. Sprint file reflects reality.

Execution order (priority-first, never cleanup-before-demo)

1. t10 — CoopActor fallback atomicity (issue #1090) Flow C is the forcing function. Everything else is secondary until this runs.

2. t5 — Commons integration test, multi-node (issue #949, S13 carryover) Proof harness. Once it passes, the pilot has a spine.

3. t11 — PatronageTracker (issue #1307) NY Corp Law §93 internal capital accounts. Unblocked now that t7 (Obligation) merged.

4. t15 — DelegationManager persist + gossip sync (issue #1309) After Flow C is stable, wire the compliance spine without chasing moving targets.

5. t16 — ExecutionReceiptGate (issue #1310) Enforces governance→execution linkage. Blocked by t15.

6. t3 — Dual-stack bind defaults [::]/[::1] (issue #1296) Low blast radius. Do last so it cannot become "mysterious networking day."

7. Hygiene

   • Merge PR #1322 (provenance call-site fixes)
   • Prune 1303-api-rename worktree (PR merged, 14 behind main)
   • Update sprint file to mark t1/t2/t6/t7 done
   • Never do bureaucracy before the demo runs.

Definition of done

• cargo test passes with CoopActor fallback covering the atomicity scenario
• Commons multi-node integration test green
• PatronageTracker tracks capital accounts per member, persists correctly
• DelegationManager survives restart via gossip sync
• ExecutionReceiptGate rejects execution without a governance receipt
• Gateway and daemon bind [::] / [::1] by default
• Sprint file updated, stale worktree pruned

Sprint 15 — Proposed Scope

Theme: Networking types refactor + cleanup batch

No new compliance surfaces — consolidate and clean.

Epics

IPv6 Phase 0+A — type model (sequential, gates later work)

1. t8 — EndpointCandidate type + ConnectionCandidate refactor (issue #1297) Core structural move: endpoints become sets of candidates with metadata, not single strings. This is the gravity item — do it first in S15 and timebox it.

2. t9 — mDNS collects all addresses per peer (issue #1298) Retain all A/AAAA results from discovery. Blocked by t8.

3. t18 — KnownPeer endpoint field + capability gating flag (issue #1300) Closes discovery → trust/capability → dialing loop. Blocked by t8.

IPv6 Phase B — dialing (stretch)

4. t13 — Happy Eyeballs multi-path dialer (issue #1299) — blocked by t8
5. t20 — TURN relay proxy IPv6 support (issue #1301) — blocked by t13 + t18

Standalone hardening batch

6. t4 — auth semantics: GET /v1/services/:id returns 404 not 401 (issue #1120)
7. t14 — timestamp validation + ServiceEndpointResponse update (issue #1051)

Semantics batch (with doc + test scaffolding)

8. t12 — extract commons credit formula to CCL PolicyOracle (issue #1308) Meaning firewall fix. Needs design doc before implementation.

Compliance continuation

9. t17 — AllocationProposal for participatory budgeting (issue #1311) — blocked by t16 (S14)
10. t19 — regulatory compliance linter CI gate (issue #1312) — stretch, goes last

Exception rule

Pull t4 into S14 only if Flow C demo surfaces unauthenticated-read behaviour that breaks the demo narrative. Otherwise it stays in S15.
