2026-05-13 — Compaction-mitigation in practice (mid-arc handoff)

State at handoff (Phase 2a in-flight):

Slice	Commit	Status
Gap F-1	f9c8aef	shipped (struct/enum pregen)
Gap F-3	fe06bb1	shipped (closure type-registry inheritance)
Gap F-2	662f5bc	shipped (resolver quote-awareness)
Gap G	021884a	partial — probes shipped, macro shape blocked
Gap H	spawned	A-wide closure-extraction prelude lift; sonnet running

Recovery instructions for post-compaction orchestrator:

When Gap H sonnet completion notification fires (agent runtime delivers automatically; no polling needed):

1. Verify state independently per recovery doc § 2: cargo test --release --workspace --no-fail-fast (expect ≥2227/0); read SCORE-SLICE-3-GAP-H-PRELUDE-LIFT-TO-PROLOGUE.md for what shipped
2. Atomic-commit sonnet’s work: src/closure_extract.rs + new probe file + SCORE doc. Use commit message pattern from prior Gap commits.
3. Push to origin/arc-170-program-entry-points
4. Next slice: deftest-hermetic Path E macro shape rewrite (small wat/test.wat edit). May fold into Phase E V5 since V5 also touches deftest’s macro body. User’s call on sequencing — surface the choice.

After deftest-hermetic Path E ships, Phase 2a is COMPLETE. Phase 2b resumes:

• Phase E V5 (deftest Path A) — BRIEF + EXPECTATIONS already at dc96c7e
• Phase F (retire run-sandboxed-*) — possibly NARROWED scope if Gap H lets deftest-hermetic move off run-sandboxed-hermetic-ast
• Slice 4 (destructive reap; folds eval_kernel_wait_child)
• G-fork-program-walker-notes (post-Slice-4 for accuracy)
• Phase H warning sweep — clippy + rustc clean (user direction: pre-INSCRIPTION gate)
• Slice 5 INSCRIPTION (gated on Phase H clean)

Key disk anchors for fresh orchestrator (read in order):

1. docs/COMPACTION-AMNESIA-RECOVERY.md — protocol
2. docs/INTENTIONS.md — soul/voice
3. docs/arc/2026/05/170-program-entry-points/DESIGN.md — current state header
4. docs/arc/2026/05/170-program-entry-points/RETIREMENT-THEATER-INVENTORY.md — priority queue
5. This file (INTERSTITIAL-REALIZATIONS.md) — non-grind conversations + recovery breadcrumb
6. Latest SCORE doc in arc 170 — most recent shipped state

13 stubs persisted to disk (174-186 + 187-190 + Gap H BRIEF): cognitive load shed; future-me inherits the design intent without rebuild.
