Focus

• paranoid: UsageAudit history & drill-down — Slice B (PARANOID-p5i.7)

Log

Sessions 15:32 (tRAGar — 3 sessions)

• Ingested tragar-wasteland-additions.md (v0.1.1-spec) and scaffolded all 8 OpenSpec change proposals: add-projector-seam, add-vector-access-export, add-neighbor-graph, add-vocabulary-chunker, add-contrastive-queries, add-clusterer-seam, add-file-store, add-intrinsic-dim-stats; all validated clean
• Ran rule-of-5-universal review: found 2 critical, 10 high, 9 medium, 4 low issues across all 8 proposals
• Fixed all 25 issues: vocabulary chunker seam violation (pooling moved to ingest pipeline), k-means/NeighborGraph mismatch (kmeans now takes Projector at construction), boundaryOf+toward rejection, unfitted/stale projector errors, k≥N clamping, unknown-id handling, Davies-Bouldin formula, TwoNN distance conversion, clear() graph invalidation, tier type broadened, seed options for UMap/KMeans, dependency sections in 4 proposals
• Arc: From raw spec additions → 8 fully validated OpenSpec proposals with no open architectural conflicts; ready for implementation ordering (neighbor-graph → projector+clusterer → intrinsic-dim-stats)
• Next: spike std::generator<Hit> → Embind → JS async iterator binding (2h gate); settle P2 decisions (tokenizer, default model)

Session 12:40 (XAct.jl — JOSS readiness)

• Read AI-generated external analysis (~/Downloads/xact.md) and corrected it against the real codebase
• Confirmed: XAct.jl has 6,954 LOC Julia, 1,200+ Julia + 900+ Python tests, CI, XPerm/XTensor/XCoba/XInvar all implemented
• Created 7 beads tickets for JOSS submission gaps: paper.md, Registry registration, CODE_OF_CONDUCT.md, CITATION.cff, and architecture/scope/license paper sections
• Ran issue-review skill (5-pass Rule of 5): found horizontal-ticket leakage, missing dep links, and untracked HITL prerequisite
• Applied all fixes: closed sxAct-hniv/jg8b/o449 (folded into sxAct-3hc7 acceptance criteria), added dep links (sxAct-kncc → sxAct-3hc7), created sxAct-6ktd (stable release tag — HITL), updated sxAct-hg1k (DOI is TBD/HITL)
• Next: Begin sxAct-3hc7 — write paper/paper.md + paper/paper.bib

Sessions 16:32 (clojnder — 3 sessions)

• Synthesized earlier Binder/Clay setup work with today’s repo-bootstrap pass for clojnder.
• Initialized wai, bd, and openspec; generated .wai/, .beads/, openspec/, AGENTS.md, CLAUDE.md, and .claude/settings.json.
• Kept setup split into two commits: existing wai init commit plus 21148e7 for OpenSpec/beads tooling and .gitignore updates.
• Pushed clojnder main after setup; openspec/project.md is still the stock template and wai sync reported no projections configured.
• Arc: Moved clojnder from Binder/Clay workflow experimentation into a repo with explicit workflow, issue-tracking, and spec-driven scaffolding.
• Next: fill in openspec/project.md, decide whether to configure .wai/resources/agent-config/.projections.yml, and create the first OpenSpec change / bd issue when the next feature is chosen.

Sessions 16:59 (clojnder — 3 sessions)

• Designed a detailed implementation plan for a full-featured JupyterLab Clay Preview: in-Lab panel, backend control API, explicit file render flow, active-file follow, save-triggered rerender, recovery UX, and Binder packaging; translated into 10 Beads issues with tracer-bullet vertical slices, 2 HITL decision tickets, and 13 dependency links.
• Resolved the two HITL preview-policy tickets; recorded approved v1 defaults in docs/clay-preview-v1-policy.md, linked from README.md and openspec/project.md.
• Created openspec/changes/add-clay-preview-extension-skeleton/, ran Rule-of-5 review, fixed all findings, validated with openspec validate --strict, and committed approved proposal as fc91d04.
• Evaluated Basilisp as a Python replacement: concluded not worth it — only 11 lines of Python, JupyterLab packaging conventions require standard Python layout, Basilisp adds compile overhead with no benefit at current scope.
• Arc: From blank repo → 10-issue implementation roadmap + approved OpenSpec skeleton proposal; clojnder-6kq is the active implementation entry point.
• Next: start clojnder-6kq with TDD — add failing registration tests, preserve the existing clay launcher entrypoint, and scaffold the prebuilt JupyterLab plugin/open command.

2026-04-30 (continued — DX/quality sprint)

• Fixed 10 issues from holistic-review in 3 commits:
  • 7148ccd: 6 DX bugs — hdr (JSON3 pkg), it7 (JSONTransport construction), dx7 (middleware stack warning), c3z (end-to-end MCP example), bxo (api.md prose), 2r9 (Unix socket status correct)
  • 26f64ee: 4 correctness bugs — a28 (UUID not mcp-prefix), 8tq (ensure_default returns UUID), r50 (done flag in error responses), fyr (LoadFile/Complete/Lookup now in default stack + exported)
  • 8df7b19: atomic session limit enforcement — ktf (deduplicated limit check helper), exj (TOCTOU race fixed via check+create under single lock, SessionLimitReachedError for clone path)
• e30 (invokelatest fast path) deferred: isdefined() at current world-age returns false for Core.eval-injected bindings; test suite blocked; overhead is sub-microsecond anyway
• 11 issues remain: 3a9 (TCP auth), gfo (MCP bypasses session limit), e9g/1jy/6sr (composition), y31/a4o/iuq/cwb (perf), gk2 (audit wiring), xvl (limit enforcement)
• Next: gfo (MCP session limit enforcement) or gk2 (wire AuditLog) or xvl (enforce max_output_bytes)

Session ~20:00 (clojnder — clojnder-a2e)

• Implemented explicit file render for Clay Preview (clojnder-a2e)
• clay_jupyter_proxy/validate.py: pure path validation — rejects absolute paths, .. traversal, non-.clj files, anything outside notebooks/ (v1 policy)
• clay_jupyter_proxy/handlers.py: POST /clay-preview/render Tornado handler; validates path, invokes clj -M:clay-render --file <path>, returns structured JSON; render failures surface as 500 without propagating exceptions
• clay_jupyter_proxy/extension.py: Jupyter server extension registering the render endpoint
• pyproject.toml: registered jupyter_server.extension_points entry
• clay.clj: added render-file! and safe-render-file! for one-shot explicit-file rendering
• render.clj: updated -main to accept --file CLI arg (falls back to CLAY_STARTER_DOC / default)
• tests/test_render.py: 21 new tests (9 validation, 12 handler); 36 total green
• Arc: TDD-first; wrote all failing tests before implementation; 36/36 green; pushed 44ae0f7
• Next: clojnder-lni (status + restart controls in the preview panel)

Session ~20:30 (clojnder — clojnder-lni)

• Implemented Clay preview status and restart controls (clojnder-lni)
• clay_jupyter_proxy/manager.py: ClayStatus dataclass, get_clay_status() (pgrep probe on clojnder.binder), restart_clay() (runs restart-clay.sh)
• clay_jupyter_proxy/handlers.py: StatusHandler (GET /clay-preview/api/status), RestartHandler (POST /clay-preview/api/restart)
• clay_jupyter_proxy/extension.py: all three endpoints wired; restart script configurable via CLAY_RESTART_SCRIPT env var
• ui/src/api.ts: getStatus() and requestRestart() fetch helpers
• ui/src/toolbar.ts: createRestartButton() factory
• ui/src/panel.ts: restart button added alongside existing Refresh
• ui/src/commands.ts: clay-preview:restart command added to palette
• tests/test_status_restart.py: 26 new tests (manager, handlers, frontend source); 62 total green
• Arc: TDD-first; 62/62 green; pushed e8c43d4
• Next: clojnder-7q2 (follow active editor) or clojnder-xfg (rerender on save) — both unblocked by clojnder-a2e

Sessions 18:50 (REPLy.jl — 8 sessions)

• 2026-04-29: Completed holistic-review passes umg.6/7/11 (session invariants, failure handling, test-suite assessment); then umg.10 (formal-verification readiness); filed 5 P1 bugs: h7o/na0/6fh/tox/exj
• 2026-04-30 morning: Completed all 13 holistic-review passes; fixed security floor (6 pre-exposure vectors: LookupMiddleware RCE, bounded message reader, LoadFile deny-by-default, module field isolation, TCP connection limit, bounded stdin); 1915 tests green

• 2026-04-30 16:53: Fixed docs API DX (2j0): stopped teaching unexported internals as primary API; updated howto-sessions.md, howto-mcp-adapter.md, index.md; docs build clean
• 2026-04-30 18:16: Fixed 10 DX/correctness/limits bugs across 5 commits (hdr/it7/dx7/c3z/bxo/2r9/a28/8tq/r50/fyr/ktf/exj/xvl/gfo/1jy/iuq/6sr); 1974 tests green
• 2026-04-30 18:50 (this session): Fixed 3a9 (TCP auth warning) — added _is_loopback() + _warn_if_non_loopback() called in serve() and serve_multi(); 2 new tests with @test_logs; security model section in docs/src/index.md; REQ-RPL-049 in openspec/specs/security/spec.md; 1976 tests green; committed db03c89 and pushed
• Arc: From holistic-review baseline → security floor → P1 lifecycle races → eval/IO/perf/DX sprint → TCP auth warning. All 13 review passes closed, all P1 bugs fixed, 1976 tests green, 5 P2 design issues remain
• Next: gk2 (wire AuditLog — quickest), cwb (per-task IO routing — unlocks true concurrency), e9g (lifecycle dedup)
