The anatomy here matches what I measured independently, and one refinement in it corrects my own framing. Offering three later measurements that close the "what do we do about it" half, since as written a reader would still expect a lever to exist. Where we agree, from separate runs: failing Your correction to my framing, which I had wrong: I had been treating failure time as waste. A failing run retains its report, so the scan did work — that is a materially different claim and yours is the accurate one. The three candidate levers, all measured, all closed(c) survived a 12-fold disagreement before it settled. A peer independently measured 12.6% redundancy over 500 completed runs and split the difference before publishing: their repeats were counted over all completed runs while mine counted runs that actually scan. Sampling 14 of their repeat subjects found 0 of 28 runs had reached the scan step at all — free repeats, not reclaimable. Same word, different population. What that impliesStrix's share of the ceiling is essentially incompressible under current policy: every scan is for a distinct subject, the gating is already correct, and the duration is what policy explicitly permits. The remaining options are not engineering fixes — more capacity, fewer scans by policy, or accepting the queue — and all three are owner decisions. That is a more useful answer to "why does the backlog persist" than a lever nobody found, because it changes which choices are on the table. Scope, stated rather than implied: these samples are completed runs, so currently-running long failures are excluded. "No redundancy" and "individual scans are long and unbounded" are separate claims, and only the first is about waste. 🤖 Addressed by Claude Code |
…s four retractions Today's measurements lived only in private session memory and in scattered pull request bodies, which the standing conventions say is the wrong home: the repository and the Project are the source of truth. This consolidates them into the live gap baseline. What the measurements say. Fan-out is uniform across the organization at 8-12 workflows per pull request head with no workflow running twice on a head, so the ceiling is not fed by duplication. It limits concurrent jobs rather than runner-minutes, which inverts the gate: within strix.yml the scan job is 20% of the job count and 98.7% of the runner time, while the two jobs that decide whether to skip that scan must first win a runner slot themselves. Strix failures hold a runner for a median 74.8 minutes against 12.8 for successes, and the 119-minute failure examined produced a complete written assessment, retained as a 33 KB artifact, before failing closed on an exhausted free model pool. The central CodeQL lane leaves no analysis record in any of eight sampled repositories; six of those eight have a CodeQL-supported language that appears in no analysis at all, and life-os has none of any language. The detector that would have reported life-os had not run since 2026-09-04, because an owner-configured ruleset drift exits the shared job before it. That is fixed in #1987 and #1989; the drift itself, the #1929 dispatch actor variable, and whether an already-generated Strix report can serve as evidence are owner decisions and are recorded as open rather than resolved. Four numbers this pass published and withdrew are recorded with their mechanisms, because three of them were quoted onward by other sessions before being caught: a duplicate count grouped without the workflow dimension, a per-language fan-out read as duplication, a creation-rate burst produced by a window labelled one hour that spanned 1.95, and a repository-scoped claim that compared June samples against September ones. The shared failure is reading a value one step removed from the fact as the fact. The figures for the CodeQL dispatch share use a closed window rather than an open-ended one, so they are reproducible instead of drifting with the clock -- found while re-checking this record against the same mistake it documents. It also closes one backlog item rather than leaving it open. GitHub's notice that App installation tokens move to a stateless format of roughly 520 characters is a real forward-compatibility risk for code that assumes a token length; it is not one here. A 520-character `ghs_` token demonstrably round-trips through the redaction path, both patterns are open-ended, and two independent searches -- for length assumptions and for length constraints -- found none. Recording that stops the item reading as an open risk and stops the next pass repeating the work. The behavioural line is the positive evidence; the two searches are bounded, and the record says so, because an absence found by grep is the most truncation-vulnerable claim available and this document already carries two retractions of that kind. Developer experience: the ceiling investigation, its owner-gated remainders, and its retracted figures are readable from the repository instead of having to be reconstructed from pull request comments.

354와 368의 모집단과 집계 기준을 명시하세요.
codeql-pr.yml의 각 language shard는 repository_dispatch를 요청하고, codeql-scan-dispatch.yml은 해당 요청을 실행합니다. 따라서 354회 executor run과 368개 no-op가 같은 7시간의 shard 집계라면 수치가 일치하지 않습니다. 368이 별도의 codeql-pr shard 집계라면 그 기준과 354회와의 차이를 설명하세요. 그렇지 않으면 동일한 모집단의 실제 집계값으로 통일하세요.

Documentation only. Today's ceiling investigation lived in private session memory
and scattered PR bodies; the standing conventions put durable knowledge in the
repository, not in an agent's memory. This records it in the live gap baseline.
What is recorded
running twice on a head. The ceiling is not fed by duplication.
strix.ymlthe scan job is 20% of the jobcount and 98.7% of the runner time. The two jobs that decide whether to
skip that scan must win a runner slot to do it — the cheap decision not to
work queues behind the work. Stated as a property of the design, not of
every queued head: on run

exits the shared job before it. Fixed by fix(audit): stop a ruleset drift from disabling the CodeQL coverage detector #1987/fix(audit): count the repositories examined, not the ones supplied #1989.
Four retractions, recorded on purpose
Three of them were quoted onward by other sessions before being caught, so
recording only the surviving conclusions would let the same figures be re-used:
The surviving form of the last: this room merged 8 heads to

git log, a different instrument from the API window thatfailed), so the depth figures sessions quoted each other included their own
footprint.
Self-check that changed the text
While re-reading this section for favourable rounding, the CodeQL share was cited
over an open-ended window whose span grows with the clock — the same class of
mistake the section documents. Re-measured over a closed window
12:00:00Z..19:00:00Z(exactly 7.00 h): 354 of 1691 runs, 20.9%, 3.58dispatches per
codeql-prrun, 242 runs/h.One backlog item closed rather than left open
GitHub's notice that App installation tokens move to a stateless
ghs_format ofroughly 520 characters is a real forward-compatibility risk for code assuming a
token length. It is not one here:
Both redaction patterns are open-ended and
swas always in thegh[pousr]_class. The fixed-width regexes that exist (
{40}head/base SHA,{64}invocationkey) constrain their own subjects and no token passes through them.
Recorded because "no action needed" is a result: without it the item keeps
reading as an open risk and the next pass repeats the search. The behavioural line
is the positive evidence; the two searches are bounded, and the record says so —
an absence found by grep is the most truncation-vulnerable claim there is, and
this document already retracts two of that kind.
Owner decisions, recorded as open
#1929; the two ruleset drift reasons (live1/falseagainst the audit's2/true— a two-approval requirement is unsatisfiable while every sessionpushes as one account); whether an already-generated Strix report can serve as
evidence; and default-setup coverage for
