…-loud session continuity Resolve all six findings from the review (none blocked landing; #1 gated enabling, #3/#4 wanted documenting). Lineage remains default-OFF and byte-identical to the fresh-box path when both flags are unset. - #1 sessionContinuity silent no-op: `continue` now asserts the session is still known to the sandbox via `box.session(id).status()` before streaming. A `null` (platform never honored the client-minted id, or it was reaped) raises a ValidationError, which executeIteration now propagates as a hard structural failure instead of degrading to a soft empty iteration — so a non-honoring platform errors loudly rather than running contextless turns. - #2 unbounded fork creation: `fork` provisions child boxes through `mapWithConcurrency` bounded by the loop's `maxConcurrency`, not a single `Promise.all` over all N branches. - #3 fork ignores per-branch specs: documented on `fork` and `LoopLineageOptions.forkFanout` that a real CRIU fork inherits the parent image/profile (per-branch specs apply only on the degraded fresh path). - #4 lineage holds every box to loop end: kernel prunes boxes no future round can descend from after each round, gated on a kernel-inferred (monotonic) branch point — skipped when the driver authors its own `parentIndex`. The unprunable case is documented as the box ceiling. - #5 abort during fork: documented the SDK's signal-less fork; abort is now checked per branch (between bounded waves) + an abort-under-lineage test. - #6 export order: alphabetized the loops barrel. Adds `mapWithConcurrency` util and six lineage tests (session-liveness pass/ fail, bounded-fork peak, mid-loop prune, no-prune-under-authored-parent, abort-under-lineage). 627 tests pass, typecheck + biome clean.

…r runLoop (backend-blind) (#150) * feat(loops): opt-in session continuation + checkpoint-fork lineage (backend-blind) Two @experimental, default-OFF seams on runLoop so a loop can CONTINUE a sandbox session across iterations (same box + sessionId, no prompt-text replay) and FORK fanout branches from a parent checkpoint (shared context prefix) — both behind a capability probe so the kernel asks 'can I fork?' (client.criuStatus) and never names Docker/Firecracker, degrading to fresh boxes when CRIU is absent. - sandbox-capabilities.ts: memoized, fail-closed criuStatus probe -> {canFork}. - sandbox-lineage.ts: createSandboxLineage owns box+session handles with start/continue/fork/teardown; reuses the kernel's acquireSandbox / buildBackendOptions / deleteBoxSafe; fail-loud if the probe says canFork but the box has no fork(). - run-loop.ts: RunLoopOptions.lineage (sessionContinuity / forkFanout); refine continues, fanout forks-once, else fresh-through-lineage. Default OFF is byte-identical to today, so random@k stays N independent fresh boxes (the compute-control invariant). Rejects lineage + onWorkerBox (both own boxes). - 7 new unit tests (continuation reuses session; fork when canFork; fresh fallback; default-off invariant). Full suite 621 pass, typecheck clean. * fix(loops): address PR #150 review — bound forks, prune lineage, fail-loud session continuity Resolve all six findings from the review (none blocked landing; #1 gated enabling, #3/#4 wanted documenting).

Adds CLAUDE.md with an Authorship directive forbidding
Co-Authored-By:trailers and AI-attribution lines on commits and PRs. Applies to every contributor, including AI subagents — explicitly overrides the Claude Code template default. Mirrors the directive already in place in@tangle-network/agent-eval's CLAUDE.md.
