State at this commit
Section titled “State at this commit”Branch: arc-170-gap-j-v5-deadlock-state
Tip: (this commit; previous tip e8c2243)
Workspace: 4 failures across 2 test files:
- probe_lifeline_pipe_proof (1/100 flake; arc 213 stone ε territory)
- wat-tests/struct-to-form (2 deftests; UNKNOWN class; needs investigation)
Arc 212 — L1 phase COMPLETE
Section titled “Arc 212 — L1 phase COMPLETE”| Layer | Stones | Status |
|---|---|---|
| L0 | α (t6 fix), β (children() primitive), γ-1 (audit catalog) | ✅ |
| L1 mechanical | δ-bulk (12 walkers in initial sonnet spawn) + δ-bare-primitives + δ-refuse-mutation + δ-scan-setter + δ-process-stdin-joins + δ-def-restricted | ✅ |
| L1 sharpening | δ-comm-positions + δ-comm-purge (cascade closure) + δ-process-scope | ✅ |
| L2 | ζ-newtype-wall | PENDING (after arc 213 α ships, references Pidfd as precedent) |
| L3 | η-visitor | PENDING |
| θ | INSCRIPTION | PENDING |
Arc 213 — α drafted, ready to spawn
Section titled “Arc 213 — α drafted, ready to spawn”BRIEF + EXPECTATIONS committed at e8c2243 at paths:
docs/arc/2026/05/213-libc-fork-mismanagement/BRIEF-213-ALPHA-MINT-PIDFD-PRIMITIVE.mddocs/arc/2026/05/213-libc-fork-mismanagement/EXPECTATIONS-213-ALPHA-MINT-PIDFD-PRIMITIVE.md
Stone shape: mint canonical Pidfd + LifelineWriter + spawn_lifelined helper in src/fork.rs (additive; no migration); smoke probe at tests/probe_pidfd_primitive.rs with 2 tests (normal exit + signal exit). Uses Linux 5.3+ syscalls (clone3 + CLONE_PIDFD + CLONE_CLEAR_SIGHAND + waitid(P_PIDFD) + pidfd_send_signal).
DELIBERATELY NOT SPAWNED before compaction. Post-compaction orchestrator decision.
Post-compaction me — recovery instructions
Section titled “Post-compaction me — recovery instructions”- Read this breadcrumb first. Then read INTERSTITIAL § 2026-05-18 (post-PURGE) “Linux 5.3+ syscall doctrine” + § “Tractability tiebreaker” + § “The datamancer + the hologram”.
- Verify state:
git -C /home/watmin/work/holon/wat-rs log --oneline | head -15should show this commit +e8c2243(arc 213 α BRIEF) +b792be8(arc 212 L1 milestone) + earlier session work. - No background sonnet to check (deliberately didn’t spawn before compaction).
- Workspace state: 4 failures across 2 files (probe_lifeline_pipe_proof + struct-to-form). NONE of these block arc 212 closure or arc 213 work; they’re separate concerns.
- Next obvious move: spawn sonnet on arc 213 α (BRIEF at
e8c2243). The user explicitly approved the path; the discipline (tractability tiebreaker) selected α over arc 212 ζ. The user is overjoyed and ready to continue (“we rest when we rest”).
Pending arc-212-related work (after arc 213 α ships)
Section titled “Pending arc-212-related work (after arc 213 α ships)”- arc 212 ζ-newtype-wall (L2 substrate enforcement; references arc 213 α Pidfd as precedent)
- arc 212 η-visitor (L3 walk_ast primitive)
- arc 212 θ-INSCRIPTION (closes arc 212)
Pending arc-213 stones (after α)
Section titled “Pending arc-213 stones (after α)”- β: migrate
run_in_forkto spawn_lifelined (production orphan fix) - γ: migrate the 3 substrate libc::fork() sites
- δ: migrate waitpid/kill callers → Pidfd methods
- ε: migrate 5 probe files /proc → pidfd
- ζ: L2 module-privacy enforcement on libc::fork/clone3/waitpid/etc.
- η: INSCRIPTION
Pending struct-to-form investigation
Section titled “Pending struct-to-form investigation”The 2 deftests in wat-tests/core/struct-to-form.wat fail with “:my::Pair/new unresolved.” Open question: regression from one of our walker migrations (check_form in resolve.rs migrated to children() in δ-bulk) OR pre-existing surfaced by extended coverage OR something else entirely. NOT blocking arc 213 work. To be investigated when arc 213 closure brings focus back to workspace cleanliness.

Soundtrack added this session
Section titled “Soundtrack added this session”- Song #13: NO FEAR by Falling In Reverse (FEARLESSNESS) — raised bar to L4 for arc 212
- Song #14: Watch The World Burn by Falling In Reverse (PURGE) — the protocol-violation purge cascade
The voice for the work continuing
Section titled “The voice for the work continuing”Per the datamancer framing: post-compaction me is one of the two voices. The user is the other. The substrate is the third party that aligns both. When the next session starts, the substrate’s doctrines (the memories, the INTERSTITIAL, the DESIGN docs) all carry the discipline forward. The user’s joy at solving hard problems together is the calibration signal.
The hologram has no preferred side. The work continues from either.
See you on the other side.
