feat: read a narrowed question back off the stored summaries - #95
Conversation
A site that narrows a question said the same thing in three places. The `requests` prop on `RollupQueries`, the `requests` prop on `RollupSummaries`, and the options on every command line reading the answers back. The third copy had nowhere to read from, so whoever typed the command repeated what the deployment already declared, and a deployment that changed its narrowing left every shell alias behind. A run that names none of the narrowing options now takes them from the summaries it read, and standard error says which it took. An option somebody typed is still theirs, and `answersSomethingElse` still stops a run whose filters no stored summary covers. Telling a filter nobody typed from one that happens to equal the default is the whole problem. `rollupRequest` fills in a value for every field of every question, so by the time a `RollupRequest` exists the two are the same thing. `RollupAsked.named` records which options arrived, read off the command line before the defaults go in. Where the summaries of a span were computed more than one way, the command names the option that would settle it and stops. That is what a change to the `requests` prop leaves in the bucket, and taking one of two narrowings would answer part of the span under a question the rest never asked. `docs/rollups/#narrowing-a-saved-copy` now says that the two `requests` props take the same shape, which is the declaration a site can already share.

📝 WalkthroughWalkthroughCommands now inherit omitted narrowing filters from stored summaries. Explicit filters remain authoritative. The CLI reports adopted filters, rejects inconsistent stored questions, and applies the settled question to limits and answer generation. ChangesSummary narrowing adoption
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to When --limit is omitted, the command can retain its default instead of using the stored summary limit, potentially returning results under the wrong row-count constraint. This correctness issue should be fixed before merging; the remaining documentation updates are bounded follow-up work. Sequence Diagram(s)sequenceDiagram

In `@docs/rollups/README.md`:
- Line 606: Update the mixed-narrowing guidance around summaryRows to state that
typing a filter does not settle a span when another covered summary used a
different value; instruct readers to use a span on one side of the configuration
change or use --query.
In `@src/cli/summary-adoption.ts`:
- Around line 103-107: Update the summary adoption flow around
questionDifferences to detect omitted --limit values by exact equality with the
requested/default limit, rather than only using coverage compatibility. Ensure
differing stored limits are included in both adoption and disagreement checks,
including spans containing multiple distinct stored limits, while preserving
existing behavior for explicitly requested limits.
In `@src/cli/summary-help.ts`:
- Around line 59-63: Update the help text describing stored narrowing adoption
to name every supported narrowing option that prevents adoption, explicitly
excluding --redirect-status and --limit; clarify that narrowing options are
available only for rollups where applicable, and state that an explicit --limit
is retained while stored narrowing is adopted.
Apply the same fix in `@docs/rollups/README.md` around lines 576 - 587: The same
incomplete option list appears in the rollup documentation, which omits
--redirect-status.

A row count is not a narrowing, and treating it as one made a deployment computing the top hundred print a hundred rows for a bare `rainlytics pageviews`. The documented default is twenty, and the stored hundred holds them. `--limit` now sits apart from the five options deciding which requests were counted. Those five are taken from the stored summaries where a command line named none of them. The row count keeps the command's own default, cut to the shallowest stored window where one of them holds fewer rows than that. A row count somebody typed is refused as before. Two windows computed to different depths therefore hold one answer between them rather than a disagreement, and only the five can be computed two ways over one span. Typing a filter no longer settles a span narrowed two ways. The windows computed the other way refuse it through `answersSomethingElse`, so the refusal offers a shorter span and `--query` and stops advising the option. The help text and `docs/rollups/` now name `--redirect-status` alongside the other four, and say what happens to the row count.

Thanks, this landed on a real seam. All three are addressed in 9540e74, though the On the row count: That also answers the second half of the finding. Stored limits of 50 and 100 covering a default 20 are not a disagreement, and neither are 1 and 5: two windows computed to different depths hold one answer between them, being the shallower of the two. Only the five counting options can be computed two ways over one span now, and On the mixed narrowings, you are right and the advice was actively bad. Typing one of the two values sends the run into On the option list, |

Resolves #85
A site that narrows a question said the same thing in three places, and the copy on the command line
had nowhere to read from. A run that names none of the narrowing options now takes them from the
stored summaries it read, and standard error says which it took.
rainlytics searches --last 7dagainst a deployment that narrowed
searchesto/liju/search/and/cidian/search/answers underthat narrowing, and the list stays in
lib/analytics/stack.tsalone.The issue offered two routes. This is the first of them, the command reading the narrowing back. The
second, one declaration both the constructs and the command read, is untouched, and nothing here
adds a home for such a file.
Telling a filter nobody typed from one whose value happens to equal the default is the crux.
rollupRequestfills in a value for every field of every question, so by the time aRollupRequestexists the two are indistinguishable.
RollupAsked.namedcarries which options actually arrived,read off
context.optionsbefore the defaults go in. A typed--pathno summary covers is refusedexactly as before.
Where the summaries covering a span were computed more than one way, the command names the option
that would settle it and stops. Adopting one of two narrowings would answer part of the span under a
question the rest never asked, and the rows would look the same either way. Typing the option settles
it, and so does a span on one side of the change. A filter somebody typed still meets the older
refusal, which names every window it disagrees with.
The line rides in the existing
summaryReportoutput, second after the coverage line. It says whichquestion the rows below belong to, and that belongs with what answered. One block on standard error
also beats two. It prints on the runs that answered, and a run refused for a filter somebody typed
gets the refusal.
One behaviour change to note. A stored summary computed with a smaller
--limitthan the command'sdefault used to be refused, and the run now takes the stored count. The refusal stands for a row
count somebody typed.
docs/rollups/#narrowing-a-saved-copynow says the tworequestsprops take the same shape, withthe constant a site passes to both.
