What this adds

An Applications in practice section in docs/EXPLAINME.adoc: one worked real-world case that shows the HWM algebra behind typed stage peaks -- the day-to-day 'which stage ate the machine?' answered auditably -- grounded in MetaManifold, an amplicon-sequencing pipeline in production use, because the value of the discipline is clearest on a live pipeline rather than a toy.

The section answers the question a newcomer actually has: what is this for in the real world, and what goes wrong without it? It is deliberately short, states what the undisciplined alternative gets wrong, and links the concrete case.

What this leaves out

Documentation only. No code, no API, no claim changes anywhere else in the repo. The commit is signed.

Versions tested

Not applicable -- documentation.

Summary by CodeRabbit

  • Documentation
    • Added a practical example explaining how pipeline memory measurements can identify the stage with the highest simultaneous memory use.

… a real pipeline

Appends a worked real-world case to docs/EXPLAINME.adoc: the concrete situation in
an amplicon-sequencing pipeline in production use where the type, the OND
discipline or the algebra earns its keep -- and what the untyped or
undisciplined alternative gets wrong. Documentation only; no code changes.

📝 Walkthrough

The documentation adds a MetaManifold pipeline example. It describes how measured stage bytes relate to Agda peaks and how the HWM instance accounts for memory across stage boundaries and handovers.

Changes: Pipeline memory documentation

Layer / File(s) Summary
Applications in practice
docs/EXPLAINME.adoc
The new section describes live-sum boundaries, handover drift, reclaimed memory, and the folded peak. It also relates the measurements to identifying the stage responsible for memory use.

…vidence

CodeRabbit (PR #11) flagged the Applications-in-practice section for
presenting the MetaManifold measurements as a production-validated result
while Instances/HWM.agda records HWM as a proposal. The claim was real but
unlinked, so: name the proposal status and its supersession rule up front,
link the concrete case (docs/occupancy-2026-10.adoc, results-2026-10-14.yml,
TypedPeak.agda, GradedStages.agda, scripts/check-occupancy.sh), give the
measured numbers the typed peak reproduces (9192, 9204, 18380 KiB), and
scope the equality to that run's observed interleaving rather than a
general production guarantee.

## Summary

Since 2026-10-15 five workflows on main (`e948265`) have failed at
startup: Governance, Rust CI, Mirror to Git Forges, Code Quality and
GitHub Pages. No workflow file changed; #11 only touched
`docs/EXPLAINME.adoc`. GitHub's runner now rejects a lock record whose
`ref:` is the record's own SHA ("invalid lockfile pin";
[standards#1271](hyperpolymath/standards#1271)).

This is step 4 of
[standards#1285](hyperpolymath/standards#1285
rollout (re-pin each caller and relock it). It's one of two test repos
before the estate-wide "apply workflow pins" run;
[rsr-template-repo#243](hyperpolymath/rsr-template-repo#243)
is the other.

## Changes

- The six standards reusables move from `934b879` to `75bd599`
(standards main). `lock-selfcheck.sh` reports `75bd599` self-consistent.
- `actions.lock` is relocked by standards' `relock-standards-pin.sh` at
`75bd599`. It gave the twelve self-SHA action records the tags standards
records for the same commits, after checking that commit and repository
ids match. No commit value changes. Only reusable-workflow records keep
a SHA `ref:` (two `cicd-suite` and `standards`), as in standards' own
lock.
- **This reverses #7's four SHA refs** (upload-artifact, setup-deno,
rust-toolchain, setup-bun).
- `tests/workflows/actions_lock_sha_refs_test.sh` asserted the form the
runner now refuses: it passes on main's lock and fails on this one.
- It now requires a symbolic `ref:` with the SHA in the key and
`commit`. It plants the self-SHA, upper-case and empty refs as negative
controls, and keeps the mismatched-commit and missing-record controls.
- It is not skipped or weakened: it now fails on main's lock, which the
runner refuses.
- CHANGELOG entry.

## RSR Quality Checklist

### Required

- [x] Tests pass (below)
- [x] No banned language patterns
- [x] SPDX license headers present (no new files)
- [x] No secrets, credentials, or `.env` files included

### As Applicable

- [x] `CHANGELOG` updated

## Testing

Run locally on this tree:
- All 19 Estate Rules steps pass, including the updated
`actions_lock_sha_refs_test.sh` (it fails on main's lock).
- `check-lock-sync.sh`, both the repo's copy and standards' at
`75bd599`: 0 dangling edges.
- `check-uuid-v8.sh --strict` from standards `75bd599`: pass.
- `git ls-remote` on the 15 SHA-keyed records with a tag `ref:`: 14 tags
point at the recorded commit.
- `dtolnay/rust-toolchain`'s `v1` has moved off `e2a55d2`. Standards'
own lock carries the same record, and the runner does not refuse it.

**Not proven by this PR:**
- Pages and Mirror run only on pushes to main, so this PR can't exercise
them. I didn't dispatch them from the branch: one deploys the site and
the other pushes to external forges. They are verified after merge.
- Code Quality and Pages call no standards reusable. They use
`editorconfig-checker@v3.0.0` and `actions/cache@v6.1.0`, whose commits
had self-SHA twin records. I have not confirmed that this is what
stopped them, because `actions/checkout`'s twin had the same shape and
its workflows started. This PR's Code Quality run is the test.
