 - [x] **Later architectural sprint: imperfect observation and source coverage** — implemented a training-friendly `complete` default plus overlay-compatible named observation profiles that apply deterministic source-level drop/delay/coverage semantics without modeling contradictions. The policy covers endpoint, network, proxy/web, firewall, IDS, Windows, Sysmon, Zeek, syslog, bash history, and eCAR source families, while ground truth preserves canonical truth and records source evidence status. Verification passed: focused observation/config/ground-truth tests, `uv run eforge validate-config`, Ruff checks/format checks, full normal `uv run pytest -v` (`3036 passed, 15 skipped`), and slow-inclusive `uv run pytest -v --include-slow` (`3050 passed, 1 skipped`).
 - [x] Observation-aware automated eval and manifest — generation now writes `OBSERVATION_MANIFEST.json` beside ground truth, `eforge eval` loads it when present, coverage-style causality metrics report raw and observation-adjusted scores for expected non-visible evidence, and correctness/contradiction checks remain strict. Verification passed with config validation, Ruff checks/format checks, focused eval/manifest tests, and full normal `uv run pytest -v` (`3047 passed, 15 skipped`).
 - [x] Post-host-activity score check — synced `dev`, cleaned up stale TODOs, regenerated/evaluated `scenarios/iteration-test` from the current iteration-test prompt with `enterprise_standard` observation, and ran one blind expert-panel review without entering another fix loop. Automated eval passed at `92.39` over `108,858` records; blind synthetic-confidence averaged `82.75`. Highest-leverage follow-ups are Linux SSH/syslog lifecycle ordering, Zeek observation-tree consistency, X.509 metadata coherence, Windows OS-build/local-SID identity, and static web asset manifests.
+- [x] Current-dev calibration pass — regenerated and evaluated `scenarios/iteration-test` from current `dev`, fixed actionable cleanliness issues in OCSP optional-field rendering, observation-manifest accounting for sensor-filtered network evidence, Kerberos/domain-logon causal ordering, storyline event timing, storyline trace matching, temporal trace comparison, and visible Windows logon-before-process ordering. Verification passed with `uv run eforge validate-config`, scenario validation with only expected sensor/observation/pivot-linkability warnings, quantitative eval at `94.64` with all hard gates passing, Ruff checks, focused regressions (`164 passed`), and full normal `uv run pytest -v` (`3075 passed, 15 skipped`).
 - [x] Full slow-suite regression cleanup after loop-65 merge — explicit-proxy storyline beacons now preserve authored hostname+destination IP pairs only when the storyline marks that pair as intentional, normal proxy-origin DNS resolution remains intact, and the parallel-generation LogonID assertion treats Type 7 unlock reuse as valid slice-of-time Windows behavior. Verified with targeted proxy/parallel tests, `uv run ruff check .`, `uv run ruff format --check .`, and `uv run pytest -v --include-slow` (`2875 passed, 23 skipped`).
   Detection Engineer blind review completed for the regenerated Loop 61 dataset at `scenarios/iteration-test/data`; reviewer verdict: Synthetic, 63/100 confidence. Main findings: one PROXY-01 sshd accepted-login lifecycle gap/self-source artifact and Windows 4648 explicit-credential caller PID/image provenance ambiguity around `WS-MCHEN-01`.
