chore(council): sweep the spikes corpus before dispatching reviewers - #837
Conversation
The council reasons about the diff. A measurement that refutes the diff's premise does not appear in the diff, so no dimension can find it by reading well. Adds a pre-dispatch sweep of docs/superpowers/spikes/ keyed on the surface terms the diff mentions, and hands the matches to the dimensions that own that surface as required reading. Written from PR #835, which added a migrated-host auth oracle reading the rendered DOM and claimed the signal was server-attested. Eight dimensions passed it — D1, D3, D6 and D10 all read the auth path closely and none objected to the premise. The refutation was five days old and already in this repository: 2026-09-11-about-redirect-is-decided-client-side.md measured that the /about hop is decided client-side with ZERO requests to Flow, and states outright that "the backend grants access while the frontend declines to open it". That one sentence invalidates the oracle. The e2e caught it instead, by going red on a live account whose state moved mid-session. That is a routing failure rather than a reviewer failure, and routing is fixable. § 2 already does memory traversal by touched path; this is the same mechanism pointed at spikes. Selectivity is the trick and it is measurable, so the filter is measured rather than asserted. Against the 37-spike corpus: `flow.google.com` hits 23 — a topic, useless as a lead — while `/about` hits 9, including all three about-redirect spikes. Terms matching more than a third of the corpus are dropped. Verified by running the documented sweep against #835 itself: it surfaces 2026-09-11-about-redirect-is-decided-client-side.md, the exact spike that refuted the PR, in a 16-file list short enough to read.

Inject spike hits into each owner prompt before dispatch. The spike command emits only terms, counts, and paths. The prompt skeleton has no spike-results block, and the dispatch instructions only require concurrent agent launch. The instruction to read each hit's verdict does not identify how matched paths reach the owning dimension. Agents can therefore start without the required verdict. Add a per-dimension block containing every matched spike path before dispatch.

Route host-only Flow diffs to the /about spikes.
flow.google.com is the documented migrated surface, but flow-[a-z-]+ does not match the dotted host. A diff containing only flow.google.com therefore produces no term; /about only helps when the diff also contains that path.
Adding flow\.google\.com alone is insufficient because the host appears in 23 of 30 spikes and the n > total / 3 filter skips it. Add a host-specific selection that narrows matches to spike files containing /about, or otherwise routes this documented host before the generic selectivity filter.

Fail closed when the diff fetch fails.
The pipeline has no pipefail or explicit error check. If gh pr diff <N> fails, the downstream commands can complete with status 0 and produce no terms. Dispatch can then continue without the mandatory spike sweep. Capture the diff and abort on fetch failure. Handle the normal no-match case separately.

Why
The council reasons about the diff. A measurement that refutes the diff's premise does not appear in the diff, so no dimension can find it by reading well.
Written from #835, which I had to draft after eight green dimensions. It added a migrated-host auth oracle that read the rendered DOM and claimed the signal was server-attested. D1, D3, D6 and D10 all read that auth path closely; none objected to the premise. The refutation was five days old and already in this repository:
That one sentence invalidates the oracle. The e2e caught it instead, by going red on a live account whose state moved mid-session.
That is a routing failure, not a reviewer failure, and routing is fixable. § 2 already does memory traversal by touched path — this is the same mechanism pointed at spikes.
What it does
Before dispatch, extract the surface terms the diff actually mentions, find the spikes that measured them, and hand the matches to the owning dimensions as required reading. Read each hit's verdict section only.
Selectivity is measured, not asserted
A sweep that returns everything is a sweep nobody reads. Counted against the current 37-spike corpus:
flow.google.com/aboutaisandbox-rootSo terms matching more than a third of the corpus are dropped.
Test plan
