feat(frontend): read the billed cost per day where a day is what is read - #2736
Merged
Conversation
The seat endpoint reports a running month-to-date total and no history, so one API object is one reading of a seat. Bronze keyed a reading by seat and extraction month over a ReplacingMergeTree, so every read inside a month was the same row and the newest replaced the rest: a month's closing figure survived and the trajectory that produced it did not. #2528 made the same move from seat-only to seat-and-month, for the same reason, and stopped one level short. Key a reading by the day it was taken and carry that day in the record as snapshot_date, matching the two ChatGPT Team snapshot streams — the only other streams in the repository whose key comes from the clock rather than the payload, and both already keyed by day. A re-run on the same day still replaces its own row rather than adding a second. `class_ai_overage_daily` carries the readings into silver beside the existing class_ai_overage, which is untouched: it holds a month's closing state, a data-quality check joins on it and the invoice-to-seat price join needs one row per seat per month. MINOR per ADR-0015, for the reason 2.1.0 was: existing rows keep their keys, nothing re-materializes, and a major bump would dispatch the one-shot `dbt --full-refresh` that this change exists to give something to rebuild from.

The committed snapshot under scripts/connectors-ddl is what a fresh warehouse is built from, and CI re-dumps it to fail on drift. class_ai_overage_daily creates a silver table, so the snapshot gains its DDL — taken from the dump the gate produced rather than reconstructed by hand.

`ai.extra_usage_cost` reports a month's billed spend against the day the seat was last read, so a chart of it puts a month's money on one day. The vendor states only a running month-to-date total and keeps no history, so a day's figure exists nowhere and can only be recovered as the step between two readings. Serve those steps as `ai.daily_approximate_extra_usage_cost`, over the readings `class_ai_overage_daily` now carries. The monthly metric keeps its grain and its exact figure; the two are alternatives, never addends, and their descriptions say so. A running total may not fall, and where it does the vendor has revised the month down. The revision belongs to the days already reported, so gold corrects each reading to the minimum of itself and every later one before differencing. Three properties follow: no step is negative, the series only rises, and the steps telescope to the month's final reading — which is what the monthly metric serves, so `sum(daily) == monthly` over a whole month holds by construction rather than by arrangement. The new e2e case asserts it for five seats, one of them corrected downwards. Evidence carries `covers_days` beside each step: a month's first point spans the days before the first reading, and a run that did not happen makes the next point span the gap. The money is real, the single day it lands on is not. Refs #2709 Signed-off-by: Gregory Gogin <grigoriy.gogin@constructor.tech>

The AI adoption section and the Overview headline both read `ai.extra_usage_cost`, which is the billing month's running total dated at the day the seat snapshot was last read. One row per seat per month cannot answer either question: the section plots a day at a time, and the headline totals a period, so a running snapshot is repeated or summed where neither is a reading. Point both at `ai.daily_approximate_extra_usage_cost`. Its per-day steps add up over any window, which is what a period total needs, and each day carries its own value, which is what the strip needs. It also removes a fragility rather than only a wrong shape: the single monthly row is dated wherever the last read landed, so an unscheduled sync moves it out of a window that ends yesterday and the figure vanishes from every surface at once. The AI & Cost header tile still reads the cumulative metric — a separate call, and a separate change. Refs #2682 Signed-off-by: Gregory Gogin <grigoriy.gogin@constructor.tech>

#2715 landed on main as a squash, so its files arrived there in their rewritten form while this branch still carried the pre-rewrite commits. Resolved passports.md, registry.yaml and ai_cost_metric_evidence.sql to main's version: this branch contributes nothing to them, and its own change is the two frontend files.

- Around line 34-35: Update the daily distribution comment to state that the
daily values sum to the period total, replacing the ambiguous claim that per-day
steps add up to one; preserve the clarification that the month's running
snapshot does not represent a period total.

Refs #2682. Stacked on #2715 — base is
feat-daily-approximate-extra-usage, which serves the metric this reads. It cannot merge before that one: the availability gate drops a key the catalogue does not carry, so onmaintoday these surfaces would simply go quiet.Why. The AI adoption section and the Overview headline both read
ai.extra_usage_cost— the billing month's running total, dated at the day the seat snapshot was last read. One row per seat per month answers neither question they ask: the section plots a day at a time, and the headline totals a period.What changed. Both now read
ai.daily_approximate_extra_usage_cost. Two keys in two config files; no component logic.It removes a fragility, not only a wrong shape. The monthly row is dated wherever the last read landed. While the only sync ran late at night that date was always yesterday, which is where the default window ends — so it fitted by coincidence. An unscheduled sync this morning moved the row to today and the figure vanished from every surface at once. Per-day steps have no single row to move.
Overview came along because the invariant requires it.
overview-configs.test.tspins every key the Overview names to one some group declares, so the two switch together. The reasoning is the same either way: that row totals a period, and only per-day steps add up to one.Out of scope. The AI & Cost header tile still reads the cumulative metric — one constant in
ai-cost-view.tsx, deliberately left for a separate call. And #2734 tracks the window that ends yesterday, which is the other half of why today's figure is invisible.Verified.
tsc -b,eslint . --max-warnings 0, and the unit suite at 201 files / 1839 tests. The suite caught the Overview invariant on the first run — switching the section alone left the headline naming a key no group declared, which is exactly what that test exists to stop.Summary by CodeRabbit
