chore: bump standards workflow pins to current main (0ef5917) - #64

…igned (#67)

## What

`Aggregate_Profile` computed means only. `Std_Dev_ISA`, `Median_ISA`,
`Category_Std_Devs`, `Category_Medians` and `Evaluated_At` were returned
**uninitialized**, and `vexometer-reports.adb` prints those fields into
CSV/HTML/LaTeX/text reports — so every generated report carried
undefined memory as real statistics.

## Why now

The E2E assertion `Std_Dev_ISA >= 0.0` failed nondeterministically on PR
#63 — the first CI test runs in this repo's history, enabled by the #66
gate repair. Identical sources passed on #64/#65/#66 and failed on #63:
classic uninitialized-read behaviour (GNAT warned `"Profile" may be
referenced before it has a value` at `vexometer-core.adb:100` all along;
that warning is now gone).

## How

- Standard deviations use the **two-pass form** — summed squared
deviations cannot go negative, unlike `E[x²] − E[x]²`.
- Medians sort a copy (`Ada.Containers.Generic_Array_Sort`), correct for
odd and even N.
- Numeric components of `Model_Profile` now default to zero, so the `N =
0` path returns defined values.
- `Evaluated_At` is stamped with `Ada.Calendar.Clock`.

## Verification

`just test` in `vexometer/`: **1282/1282 assertions pass**, three
consecutive runs, exit 0 each (previously flaky). No manifest-tracked
files touched.

## Summary

Closes out the 2026-09-01 decode-and-repair pass with the situation
report and the last mechanical documentation fixes. Everything narrative
lives in the sitrep itself: **docs/sitrep-2026-09-01.adoc**.

- **Sitrep** — repo/branch state and the lossless rebase resolution, the
quality-gate outage (#66) and the two defects the repaired gates caught
immediately (#67 uninitialized profile statistics, #64 unparseable
workflow-linter), the verified Anthropic-paper provenance and the
ISA/safety-alignment boundary, a documentation honesty audit, and a debt
register (D1–D7) with done-conditions.
- **STATE.a2ml** — `last-updated` refreshed; the 25%-vs-70% divergence
and the assertion-execution counting convention annotated (true refresh
= D3).
- **SATELLITES.adoc** — dead `.scm` links repointed to
`.machine_readable/6a2/*.a2ml`; retired-format NOTE on the ECOSYSTEM.scm
template section.
- **vexometer-satellites/README.adoc** — false claim to hold the
protocol specs removed; dead `docs/*-format.adoc` links repointed to the
real specs; trust manifest regenerated in the same commit per the
manifest contract.
- **TEST-NEEDS.adoc** — the 1282 figure annotated as assertion
executions (420 loop-amplified), ~55 static sites.

## Verification

- `bash scripts/run-must-gates.sh` → exit 0, "all must gates passed"
(with the regenerated vexometer-satellites manifest).
- All links added here resolve on this branch; no `link:*.scm` remains
in SATELLITES.adoc.
