M5 Composition Specimen and the Fresh-Actor Pre-Dispatch Repair

August 26, 2026

Ran the M5 composed autonomy cycle for real, hit a genuine handoff-mechanism defect on first live use, stopped without patching mid-experiment, then repaired it as its own bounded Charge.

Timeline

Start

M5 Charge received

Compose Strategist → Charge → fresh Actor → verified terminal result, one cycle only

Orient

Explore agent mapped current machinery

Found the real M5 Charge from 2026-08-25 still frozen, unconsumed, hypothesis still current

Strategist

Reused the existing frozen Charge instead of minting a new one

Re-verified via npm run guard — both cited drift numbers unchanged

Handoff

Dispatched via spawn-fresh-actor.mjs --wait

Script crashed before reaching gh workflow run

Stop

Recorded the composition failure, did not repair mid-specimen

Full M5 final report written with PARTIALLY DEMONSTRATED assessment

Repair Charge

Zeb issued a separate, bounded repair Charge

Root cause verified, one-line fix, regression test, mechanical re-verification

Pushed d6f3ebf7 to origin, wrapped session

No M5 re-attempt — that's explicitly the next session's job

What shipped

Ran one real M5 composition specimen: Strategist correctly recognized and reused the already-frozen, still-current M5 Charge (forgekit-os/charges/m5-real-continuation-cycle-2026-08-25-charge.md) rather than minting a redundant new one

Attempted handoff via the existing fresh-execution boundary (forgekit-os/scripts/spawn-fresh-actor.mjs --wait) — discovered and precisely diagnosed a real, previously-unknown defect in the pre-dispatch presence gate before any Actor was ever spawned

Wrote the full M5 final report (14 sections) with assessment PARTIALLY DEMONSTRATED, per the Charge's own Composition Failure Rule — observed and stopped, did not patch and retry within the same specimen

Executed a separate, explicitly bounded repair Charge: fixed forgekit-os/scripts/spawn-fresh-actor.mjs (line 58, run(['fetch',...]) → execFileSyncGit(['fetch',...])) — a git subcommand had been routed through the gh-shelling helper

Added forgekit-os/scripts/tests/spawn-fresh-actor.test.mjs — 4 source-level regression tests, wired into npm run test:os — verified the tests actually catch the pre-fix bug by extracting and checking the pre-fix committed source

Mechanically re-verified the repaired pre-dispatch gate end-to-end (both fail-closed on an absent Charge and success on the real, present M5 Charge) using real git/gh calls, without ever dispatching an Actor

Committed (d6f3ebf7) and pushed to origin/master

“provider completed ≠ work completed”
— M5 Charge, restated and directly exercised this session — a GitHub Actions 'success' or a clean script exit was never treated as evidence the actual work happened.
