# Day 16 · Dates help show a service change

**Goal:** Sequence dated source editions and explain continuity/change without inventing cause or completion.

**Partial codes:** AC9HS4K08, AC9HS4S02, AC9HS4S03, AC9HS4S05, AC9HS4S07; original task criterion, not official grade.

**Ready:** C11/C12, exact named F facts, empty paper area/description; supplied aids or whole alternatives. Hold selected later/key.

**0–3 Begin:** Invite notice/question, offer routes and usual support. Not sure, new start or pause valid; no previous attendance/mastery assumed.

**3–8 Model:** C11 fictional notices:2 March 2027 BALL/CHALK trays;5 March same trays plus return-time label;9 March same plus question slot. Equal timeline spacing is not measured elapsed time. Model added label, retained trays and unknown cause. These are plans/notices, not use records.

**8–13 Guided:** Give editions out of order. Locate date/words before arranging. Annotate one change and one continuity. Compare C12 request-status log: requested and acknowledged do not establish inspection or repair.

**13–23 Own useful work:** Make annotated date list/timeline with a missing reason/effect question. Two editions suffice; describe or direct arrangement. If earlier lessons missed, supply required cards openly, not as a recall test.

**23–27 Inspect and next teaching:** Look for supported date order/annotation. If requested becomes repaired, contrast exact status words. If a motive is guessed, label hypothesis or request reason source.

**27–30 Keep/finish:** Keep, revise or leave useful part; preserve factual credit, supplied-case/actual-use/possible-effect distinctions. Missing response is not yet observed; offer another sitting.

### Three selectable mechanisms

- R16A: Arrange dated edition cards and attach retained-feature and changed-feature annotations.
- R16B: Inspect request log and explain why later date alone does not establish completion; develop a status question.
- R16C: Give a spoken/signed mini-documentary with source names, dictated continuity/change and limit; no audio recording.

**Coupling:** same Day in CHILD-AND-WRITTEN; C11/C12, H06, X06. Assessment selection explicit in own-work, never automatic.
