Session log — 2026-06-01

A three-phase session that closed the post-M14 foundation work + filed the long-tail sub-issues + closed out the parked foreign-WIP triage.

Phase 1 — Foundation (7 PRs)

PR What
#59 RSR-template gap fill: 188 {{project}} / {{PROJECT}} / {{BUILD_CMD}} placeholders replaced with project-scoped names across 10 files
#67 Coq single_op_reversible Qed-closed via OpMkdirWithPerms + OpCreateFileWithPerms constructor variants; zero new axioms
#62 Crash-consistency keystone: docs/THEORY-CRASH-CONSISTENCY.adoc + Lean 4 crash_atomic_within_op_mkdir; closes #45 keystone
#69 Idris2 Filesystem/Model.idr typecheck fix: Data.Maybe import + Eq Path + Eq FSEntry instances
#72 secure_delete (3-pass + fsync + unlink, /dev/urandom on Unix) + audit_log (XDG_STATE_HOME, JSON-lines) + 20 prop-correspondence tests; 757/0 cargo-test pass
#68 Maintenance: M2 ROADMAP refresh, M3 doc-TODO sweep (81→74), M4 30 cargo bumps + 5 GH Action SHA bumps
#73 cargo-fmt sweep across 44 files in impl/rust-cli/

Issues filed: #60, #61 (RMO theorem-shape redesigns — type signatures are non-theorems, not hole closures), #63-#66 (4 crash-consistency frontiers), #70 (Idris2 build oracle infra), #71 (CodeQL JS/TS regression).

Phase 2 — Option 2 + clippy + artifacts (4 PRs, 17 sub-issues)

PR What
#74 Clippy sweep: 86 -D warnings errors → 0 across 34 files (auto-fix + 26 manual + 7 allow-listed-with-rationale) + 8-file fmt fixup
#75 Remove accidentally-tracked artifacts: impl/rust-cli/$FILE (literal "test\n") + impl/rust-cli/.vsh_state.json (vsh runtime state from PR #73's test session); add both to .gitignore

Option-2 sub-issues filed (one-PR-sized chunks):

  • Under #42 (478 theorems): #76 Lean 4 · #77 Coq · #78 Isabelle · #79 Agda · #80 Mizar · #81 Z3
  • Under #43 (test expansion): #82 property-correspondence · #83 security · #84 benches · #85 fuzz
  • Under #41 (escape hatches): #86 unreachable! · #87 panic! · #93 TODOs · #94 Idris2 partials
  • Under #45 (theory + practice): #88 concurrency · #89 POSIX 2024 · #90 GDPR/RMO · #91 Lean→Rust · #92 remaining gaps

Phase 3 — M1 foreign-WIP triage closure (9 PRs)

Decisions taken on the long-parked WIP at /home/hyperpolymath/developer/repos/valence-shell branch claude/safedom-res-stale-sweep:

Decision Outcome
proof/admit-becomes-admitted branch DROPPED — would have regressed #67's OpMkdirWithPerms work
proof/valence-work branch DROPPED — already on main via PR #47 (docs(proof): proof narrative ...)
267-file copyright sweep LANDED as 7 language-batched PRs (#95-#100) + LICENSE PR (#101) + taxonomy PR (#102)
2× [gone] branches PRUNED (claude/tech-debt-2026-05-26 + panic-fix/PA001-PA007-ffi-legitimate; both already merged via #32/#35)
claude/cicd-audit-2026-06-01 branch DROPPED — same fixes are already on main via a different commit; salvaged the SHA-pin part as PR #103

8-batch SPDX sweep:

PR Files Batch
#95 105 Markdown (HTML <!-- --> comment block)
#96 70 Rust (// line comments)
#97 44 AsciiDoc (//)
#98 22 Zig + C + H (//)
#99 11 Elixir (#)
#100 10 Idris2 (--)
#101 1 LICENSE: drop Palimpsest preamble → plain MPL-2.0
#102 4 + 1 rename Anchor taxonomy: .machine_readable/anchors/ → .machine_readable/6a2/anchor/ + 6a2 manifest + README
#103 2 SHA-pin standards/governance-reusable.yml@main → @1376eb62

Reusable injector script: /tmp/spdx-sweep/inject-copyright.sh (deterministic, idempotent, handles <!-- --> + // + -- + # comment styles, detects existing SPDX/Copyright and inserts/prepends appropriately).

Final state

  • Local branches: 1 (main, matching origin/main at abd5767)
  • Open PRs: 0
  • Stash safety net: 1 entry (M1 closure 2026-06-01 — superseded WIP backup) — content fully captured in PRs #95-#103, can be dropped any time

Critical technique gains

  1. Theorem-shape audit beats hole-closure attempts. RMO.idr ?holes were non-theorems by type signature, not gaps to fill. Filed #60/#61 with corrected theorem shapes derived from Coq's obliterate_not_injective.
  2. OpMkdirWithPerms = clean closure path for #67. Constructor-variant + pre-state-threading approach beats the funext strengthening alternative.
  3. Path-filtered workflows hide drift. rust-cli.yml only runs on impl/rust-cli/** push/PR paths, so main pushes that don't touch those paths skip the workflow and let cargo fmt --check drift accumulate silently.
  4. Idris2 stdlib install brittleness. Local Idris2 install at ~/.asdf/installs/idris2/0.8.0/ has metadata only, no source for rebuild. Filed #70 to fix in CI.
  5. cargo clippy --fix is the right first step. 86 errors → 60 auto-fixed → 26 manual. Saves ~2 hours on a clippy sweep.
  6. Allow-list-with-rationale beats blind fixes. Some clippy suggestions would break semantics (matrix init range loop, shell-operator branches, custom Option<Self> return). Each allow-list site documents the rationale.
  7. Cross-repo Closes doesn't auto-fire. Sub-issue cross-refs in parent issues use comment-with-link pattern instead.
  8. Honest M1 triage is read-only. Pre-decision inspection avoids destructive mistakes on foreign WIP.
  9. Deterministic injector > stale-patch replay. When a long-parked WIP can't git apply cleanly against current main, a deterministic script that reproduces the intent against current state is faster + safer.

Outstanding (post-session)

  • #60, #61 — RMO.idr theorem-shape redesigns await owner approval before Idris2-side GDPR claim can be CI-verified.
  • #70 — Idris2 build oracle infra still needed (Justfile target + CI job + stdlib provision).
  • #71 — CodeQL JS/TS regression resolution pending.
  • Sub-issues #76-#94 — PR-sized work units, awaiting implementation cycles.
  • Stash entry at /home/hyperpolymath/developer/repos/valence-shell — drop when ready.
