ICN Roadmap — Live

Last updated: 2026-04-08 (Post-Sprint 28 — Governance Dispatch Tranches)

This document tracks sprint-level progress against the ICN development roadmap. For architecture and phase history, see docs/ARCHITECTURE.md and docs/PHASE_HISTORY.md.

Current state (2026-04-08)

Active workstream: Post-Sprint-28 governance dispatch tranches. The sprint-numbered planning cadence ended with Sprint 28; active work is now organized as sequential "Tranches" against the executor-wiring and ADR-0016 closure epics.

What landed between Sprint 23 and the current work (summarized; see git log for detail):

• Sprint 24 — Commons-compute spine. Two-tier trust threshold for pool admission, stale participant expiry, V1 scheduling-time credit enforcement floor. Closed 2026-03-23. See docs/strategy/sprint-24-close.md.
• Sprint 25 — ADR-0016 Phase 2 work. Closed via chore(ops): close sprint 25, open sprint 26 (commit 92de849e).
• Sprint 26 — Interim tranche; see commits between 92de849e and Sprint 27 opening.
• Sprint 27 — Demo-Ready + Compute Story. Flow 5 commons compute trust-gated admission, demo polish, website five-flow update, summit proposal. Key commits: 1600a1fb, b1ba40c7, cb22e1e5, 8ab59cff.
• Sprint 28 — Gossip fan-out fix (compute task delivery restored). Commit 4ae8401f (PR #1419).

Governance Dispatch Tranches (post-Sprint 28, active):

The canonical source of truth for tranche status is docs/architecture/agent-handoff-current.md and git commit messages tagged Tranche N. At time of writing:

An overlaid "Agent Handoff Tranche" track (I, II, III, ...) in docs/architecture/agent-handoff-current.md covers ADR-0016 closures (surplus reserves consumption, charter view persistence, etc.) and advances on its own cadence. Tranches I, II, and III all closed 2026-04-08.

Rule: Do not treat the per-sprint sections below as current status. They are historical only. For current state, read this block, git log, and docs/architecture/agent-handoff-current.md.

Completed Sprints

Sprint 22 — Meaning Firewall Completion

Theme: Complete extraction of all hardcoded policy constants to typed config structs Status: Closed 2026-03-22 Completed:

• icn-security: max_violations_per_hour + violation_retention_secs extracted to MisbehaviorThresholdsConfig (PR #1389)
• icn-obs: 5 attestation threshold constants extracted to AttestationConfig (PR #1390)
• icn-compute: CharterPriority preemption routing + credit ceiling validation extracted to ComputePolicyConfig (PR #1391)
• icn-ledger: CreditPolicy + NewMemberPolicy factory values extracted to CreditPolicyConfig (PR #1392, highest regulatory priority)
• docs/meaning-firewall-audit.md updated to mark all Sprint 22 remediations complete (PR #1392)

Sprint 23 — Baseline Lock + Narrative Surface

Theme: Legitimacy through convergence. Repo state, board state, and narrative state must agree. Status: Active (2026-03-22) Governing rule: A task is only "done" when repo state, board state, and narrative state agree.

Track A — Operations Closure

• s23-t1: CI Test Coverage classified as non-blocking observational gate (commit 57f5cc00)
• s23-t2: Dirty file committed — session log from #1394 skills rewrite (commit 627857a2)
• s23-t3: Stale 1310-execution-receipt-gate worktree removed
• s23-t4: Sprint 22 formally closed; Sprint 23 board populated

Track B — P0 Residue

• s23-t5: #1095 CRDT OrSet + LwwRegister — deferred to Sprint 24 with rationale (pending)
• s23-t6: #1096 ContainerRuntime trait — implementation in icn-kernel-api (pending)
• s23-t7: #1131 Storage governance spec written; issue closed (commit e16625bc)

Track C — Baseline Narrative

• s23-t8: Platform baseline document published (docs/state/ICN-Platform-Baseline-2026-03.md) (pending)
• s23-t9: Roadmap refresh — this document (in progress)
• s23-t10: Demo path validated and documented (pending)

Sprint 24 Candidates — Commons Compute Hardening

These are shaped candidates only. Full Sprint 24 planning is out of scope for Sprint 23.

#925 — feat(compute): Commons resource pool and contribution accounting

• Scope: CommonsPool type for aggregate capacity tracking across all commons participants; unaffiliated node participation; commons credit earning/spending proportional to contributed resources
• Rationale: First full Commons Compute primitive — enables nodes without org membership to participate in resource pools and earn commons credits

#947 — feat(compute): Unaffiliated node participation protocol

• Scope: Protocol for independent (cell-less) nodes to announce capacity with commons_share = 1.0, claim Commons-scoped tasks, and submit execution receipts for settlement; gossip integration for NodeCapacityAnnounce with cell_id: None
• Rationale: Depends on #925; makes commons participation legible at the gossip layer so task placement can route to commons nodes

#964 — feat(compute): Stale commons pool participant expiry

• Scope: Configurable expiry logic (default 5 minutes) to evict commons participants that stop announcing; periodic expiry check on new announcements or background timer; expiry metrics
• Rationale: Closes the last_announce TODO in icn-compute/src/commons_pool.rs; prevents stale nodes accumulating indefinitely in pool capacity accounting
