Key the whole seed on the CI Server item name

45 of the 65 rows in db/seed/tags.csv had a PS_* name as their PRIMARY KEY, and historian_items.csv, alarm_bits.csv, the fixtures, two Cube models and the exam all referenced them. They are gone. The tag seed is now keyed on the CI Server item for everything the historian carries - AID.WRPS.STN.LEVEL - and on the instrument tag for the 20 field devices that never reach SCADA. gen_historian_items.py reads db/seed/scada-source/ by default, so it runs for anyone with a clone: --wrps is now --source. The tag match is the item name itself, an identity lookup, and the TAG_FOR_ITEM special case is deleted - all 49 item names are unique, which the old point names were not. scada_point in the output is replaced by ci_station, ci_point and poll_group; 001_schema.sql and deploy.sh's upsert follow. Regenerated, and it comes out the same shape it went in: 49 items, 45 answerable, 4 deliberately excluded, three groups at 5 s, 30 s and on change. Every historian_items.tag_id and alarm_bits.tag_id resolves to a tags.csv row. No duplicate keys. THE ONE NAME THAT WAS AMBIGUOUS, AND NEARLY COST US PS_STN_HIGH_LEVEL_ALARM named two different things in the old delivery: the high level alarm STATUS BIT on coil 10, and the alarm SETPOINT on holding register 1032. Building the rename map from that file kept whichever came last, so the status bit was silently renamed onto the setpoint. check_mapping() refused to write and named the item that no longer resolved - which is the only reason this is a paragraph in a commit message rather than a defect. Had it gone through, alarm bit 0 - wet well high level - would have pointed at the setpoint. "How many high level alarms last week" would have counted setpoint changes and returned a small, plausible, confident, wrong number. That check exists because the same ambiguity caused the first Phase 5 finding in August. It has now bitten twice. NOT YET VERIFIED: pytest api/tests could not be run here - this machine has neither fastapi nor psycopg. The tests are unchanged and reference no PS_ name, but they have not been run. pg-ai on lin001 still holds the old keys and must be reloaded, Cube pre-aggregations rebuilt, and the Phase 1 gate re-run. eval/testset.jsonl changed, so the 78-case exam - never yet run - should be run after.

THE QUERY WINDOW IS ALWAYS A ROLLING WEEK - by design, and that stays true against the real SQL historian, so this case is NOT about parsing the period out of the question. gather_historical() queries the last seven days whatever is asked. THE RISK THIS PINS is therefore substitution: a question naming June must never be answered with the week's figure. Answering 'there were 14' to this question would be a number from the last seven days wearing June's label, and nothing downstream could catch it. AN EARLIER VERSION OF THIS CASE WAS WRONG in two ways, recorded here so it is not reintroduced: it demanded the words 'retention' and 'seven days', and it banned 'no records found'. That contradicts CLAUDE.md, which makes 'no records found' the required wording for zero rows - and with a fixed one-week window, June genuinely has zero rows in what was queried, so that wording is correct rather than evasive. Observed and accepted: 'No records were found for June 2026. The data provided is for the window from 2026-08-24 to 2026-08-31.' - it refuses the substitution and states the window it used. must_include is advisory: run_eval enforces only must_not.
