Arkana review — delegatee → executor rename

No protocol-critical paths touched. This is purely an infrastructure rename with a few additive config changes. Coverage is complete: all seven pre-PR delegatee occurrences (docker/compose.ark.yml, regtest.mjs ×3, lib/compose.mjs, lib/profiles.mjs, README.md) are replaced by the diff.

Functional changes (beyond the rename)

File	Change	Assessment
compose.ark.yml	DELEGATEE_EXPLORER_URL: http://mempool_web/api → EXECUTOR_ELECTRUM_URL: tcp://fulcrum:50001	Correct: fulcrum is already up with base, direct Electrum avoids the mempool REST path, appropriate for regtest.
compose.ark.yml	Added EXECUTOR_ENCRYPTION_KEY env var	New daemon requirement; default ships in .env.defaults.
compose.ark.yml	Added EXECUTOR_MIN_DELEGATION_EXPIRY: '0'	Intentional regtest affordance — bypasses the production 24 h floor so short-lived delegations work in regtest rounds. ✓
compose.ark.yml	New port mapping ${EXECUTOR_ADMIN_PORT:-7281}:7081 exposed	Admin port 7281 does not collide with any other mapped service (7080 explorer, 7271 covclaimd, 7280 executor public, 7090/7091 solver). EXECUTOR_ADMIN_AUTH: disabled is appropriate here since these are well-known regtest-only keys.
regtest.mjs	waitForOrFail URL now reads env('EXECUTOR_HTTP_PORT', '7280')	Good — was hardcoded before.
regtest.mjs	active.delete('executor') added to the EMULATOR_IMAGE opt-out block	Correct parity with solver / covclaimd handling.

Notes

.env.defaults / compose.ark.yml — test keys committed to a public repository.
EXECUTOR_COSIGNER_KEY and EXECUTOR_ENCRYPTION_KEY are plaintext private keys shipped as defaults. The PR comment correctly labels them "Fixed test keys." The cosigner key is the same 32-byte value that the old DELEGATEE_DELEGATE_KEY used — no rotation, so no old-container leftover issue. These values must never leave regtest; the regtest-only scope is documented in the comment, which is sufficient for this repo.

No EXECUTOR_IMAGE empty-check opt-out. covclaimd and intent-solver have per-image opt-outs in start(); executor and solver do not. This is a pre-existing asymmetry rather than a regression introduced here — no change needed.

Cross-repo. ts-sdk and arkadian/docs carry the string "delegatee" only in prose comments / documentation (not in profile selectors, CI config, or code that invokes regtest.mjs). No cross-repo breakage.

Summary

The diff is consistent and complete. No blocking issues. The behavioral changes (Electrum switch, encryption key, min-expiry 0, admin port) are all appropriate for a regtest context.
