executor-sandbox / executor-worker — Architecture Findings

Document status: Dated investigation record, non-normative, append-only. Triggered by the org-wide TRSL rollout follow-up (history/260730-TRSL-OrgWideLicenseRollout.md): the maintainer asked what executor-sandbox and executor-worker actually are, how they relate to sand-boxer, glas-harness, rein-aharness, kaizen-agentic, agentic-resources, phase-memory, and llm-connect, and to establish/update their INTENT.md/SCOPE.md from real repo content.

---

1. executor-sandbox — reconciled

Finding: the local ~/executor-sandbox directory on this workstation is a stale, disconnected local clone — its git history (init sandbox, executor smoke: add NOTES.md) is completely unrelated to the real Forgejo coulomb/executor-sandbox repository's history (init: sandbox for harness smoke, then timestamped harness smoke: <ISO8601> commits from 2026-07-18 and 2026-07-26). The local directory had no origin remote configured at all — it was never actually wired to the real repo.

The real Forgejo repo is a disposable smoke-test target for rein-aharness (see §3): its SMOKE.md literally reads "rein-aharness smoke," and its commit history is a stream of automated smoke-run timestamps, not human feature work.

Action taken: worked directly against a fresh clone of the real Forgejo repo (not the stale local directory). Established INTENT.md and SCOPE.md there from its actual observed purpose (disposable smoke target, no independent product scope), and applied TRSL V1C1. Committed and pushed to coulomb/executor-sandbox.git directly.

Left as-is, flagged: the stale local ~/executor-sandbox directory on this workstation still contains its old, disconnected history and our earlier (now superseded) license commit on top of it. It was never the real repo, so nothing of value was lost by leaving it alone, but it may be worth deleting/re-cloning that local directory so it doesn't confuse a future session into thinking it's a working copy of the real repo.

2. executor-worker — retired prototype, no Forgejo repo exists

Finding: executor-worker's own README.md already says it plainly:

"executor-worker (retired prototype) — Adopted into the shared runtime repo agent-harness on 2026-07-17 (DEC-2026-002 / agent-harness ADR-001). Package renamed to agent_harness; all further work happens there (HARNESS-WP-0001). This directory is kept only for the prototype git history."

Confirmed via git ls-remote: no coulomb/executor-worker repo exists on Forgejo, and no coulomb/agent-harness repo exists either — because agent-harness was itself later renamed again, to rein-aharness (glas-harness ADR-001, 2026-07-26), which does exist and is live.

The maintainer's own founder note (binky-control's integrations/llm-connect-executor-assessment.md, 2026-07-16) is the origin of this whole lineage: "llm-connect should enable real automated work based on activity-core independently from this workstation... This will hopefully connect well with kaizen-agentic, too." That assessment's "Ownership decision (2026-07-17, BINKY-WP-0004-T01)" recorded DEC-2026-002: the executor worker lives in a new small repo, not inside activity-core or kaizen-agentic. That new small repo was executor-worker, prototyped to completion (64681e7 MVP, 31a8566 mail-scan mode), then formally adopted/renamed to agent-harness, then renamed again to rein-aharness.

executor-worker's function is not missing — it already has a live, production successor. No new Forgejo repo is needed to "complete" this lineage; rein-aharness already is that repo, already has its own INTENT.md-equivalent scope, and is deployed live on Railiance for tenant binky-control.

Resolved (maintainer, 2026-07-30): no coulomb/executor-worker Forgejo repo will be created — rein-aharness is the real, live successor and already carries the lineage forward. The local directory was moved to ~/archive/260717-executor-worker-retired/ (timestamp is the repo's own actual retirement date, per its retire: prototype adopted into agent-harness commit) to get it out of the way of the active workstation directory listing, git history preserved intact by the move.

3. Full architecture map (verified against each repo's own SCOPE/README/ADRs)

activity-core (Temporal schedules, Railiance)
   └─ definition fires → rule emits task → issue-core (REST task sink)
        └─ glas-harness (meta-framework/router, ADR-001, 2026-07-26)
             owns the harness CONTRACT (session lifecycle, tool dispatch,
             actor attribution, sandbox consumption) — routes to
             pluggable concrete backends called "reins":
             │
             ├─ rein-aharness (formerly agent-harness, formerly the
             │    executor-worker prototype) — Claude-Code-CLI-driven,
             │    deployed live on Railiance for tenant binky-control
             │
             └─ rein-openweights — drives current open-weight models via
                  OpenRouter; the gap ADR-001 explicitly named ("no
                  harness today runs an open-weight model") and filled

  glas-harness consumes sand-boxer for OS-level isolation (the reins
  themselves, per ADR-001's own Context section, historically had *no*
  real sandbox — sand-boxer is what fixes that gap for both reins
  uniformly, rather than each rein reinventing its own isolation).

  Both reins use llm-connect as their LLM adapter "engine block" (a
  provider-neutral client library, explicitly not an agent framework
  itself per its own SCOPE) — ClaudeCodeAdapter for rein-aharness,
  OpenRouter-backed adapters for rein-openweights.

  kaizen-agentic supplies agent personas + project memory + coordination
  (get_kaizen_agent) — its own WP-0006/ADR-005 ("scheduled agent
  execution via activity-core") is the exact convergence point the
  founder's 2026-07-16 note hoped for. Kaizen's own verb is "prepare,"
  not "execute" — runtime execution is the reins' job, not kaizen's.

  executor-sandbox is rein-aharness's disposable smoke-test scratch
  target (§1) — infrastructure supporting the harness, not a product.

phase-memory: "the profile-driven memory operating layer for agentic systems... interprets Markitect memory profiles as runtime plans, models memory phases, and produces deterministic dry-run actions for retention." Not directly named in any of the ADRs/assessments read for this investigation — its relationship to kaizen-agentic's own "persistent project-scoped memory" is plausible (both are agent-memory concerns) but not confirmed cross-referenced in either repo's own docs during this pass — flagged as needing a closer look if the maintainer wants that relationship pinned down precisely, rather than asserted here without verification.

agentic-resources: still carries an auto-generated, unrefined statehub register placeholder SCOPE ("Iterating towards optimal agentic performance" — a one-liner with no elaborated Core Idea beyond restating INTENT.md exists). Its session_memory/ directory contains stored session blobs from multiple agent CLIs (Grok, Claude), suggesting it may be functioning as a de facto session-memory scratch store — possibly overlapping with phase-memory's stated purpose, but this repo's own scope is genuinely too thin to confirm that relationship confidently. This repo's SCOPE.md itself is a candidate for the same "outdated/unrefined, should be updated from actual content" treatment the maintainer asked for on executor-sandbox/executor-worker — flagged, not fixed in this pass (out of the scope the maintainer actually asked about).

4. Utilization signal (what's actually active vs. dormant)

Based on commit recency and status: finished/status: active workplan markers found during this pass:

• Actively developed / live: rein-aharness (live on Railiance), glas-harness (ADR-001 dated 2026-07-26, recent), rein-openweights (exists specifically to fill ADR-001's named gap), sand-boxer (consumed by glas-harness).
• Stable, supporting role: llm-connect (pre-release 0.1.0 per the 2026-07-16 assessment, adapter library, not itself under heavy churn), kaizen-agentic (mature, v1.1.0, 18-agent library, active WP-0006 for the scheduling convergence).
• Retired: executor-worker (explicit, by its own README).
• Throwaway/infrastructure, not a product: executor-sandbox.
• Unclear/thin: agentic-resources (§3) — not confidently placed in this architecture map without further investigation.

5. Non-goals of this document

• Creating a coulomb/executor-worker Forgejo repo — explicitly left as an open question for the maintainer (§2), not decided here.
• Refining agentic-resources' own SCOPE.md — flagged, not fixed.
• Confirming the phase-memory ↔ kaizen-agentic/agentic-resources relationship with certainty — flagged as unconfirmed, not asserted as fact.
