b21 launch-4 --- Cross-link grid (P-1 priority tier)
================================================================================

| **Mode:** EDEN
| **Effort:** Max
| **Run order:** 4 of 7 in the b21 launch-sprint sub-prompt set.
| **Status of upstream:** P-1 tier of the cross-link grid scoped
  in :doc:`b20 review llog
  </matheology/hell/ll/infra/b/20/b20-launch-unit-review_2026m05d22>`
  §7-2 + §5.4. Extends the 3 critical inline links from launch-3.

1. Context
============

The b20 §5.4 cross-link plan defines three priority tiers:

- **P-1** *(this prompt)*: launch-critical links between the
  highest-traffic papers.
- **P-2** *(launch-7)*: full N×N grid across b11--b21.
- **P-3** *(launch-7)*: b18-esc variants + b21 (AI framework) to
  all other papers.

This prompt covers P-1 only. The criterion for P-1 inclusion: a
sympathetic reader landing on any P-1 paper should be one click
away from the others on the same tier.

The 3 critical inline cross-links from launch-3 are a subset of
P-1; the rest of P-1 fills in the surrounding grid.

----

2. P-1 link list
==================

Add the following ``:doc:`` cross-links. The format is
**from-paper → target**.

For each target paper:

- Add a *"Related papers in the Matheo series"* subsection in
  the SI or Appendix (or wherever the paper's existing
  cross-reference block lives). Format as a short RST list with
  ``:doc:`` links + one-line descriptions of each linked paper.
- Where the target is already discussed inline in the paper's
  main text, also add an inline ``:doc:`` link on the first
  mention (similar to launch-3's L-B18A-3, L-B18A-4 inserts).

**b11 (PET):**

- → Matheo overview (``/study/matheo/index``)
- → b18a (Call to Action) [paper that builds on PET]
- → b19 (SGIR) [paper that applies PET-adjacent thinking]

**b18a (Call to Action):**

- → Matheo overview (``/study/matheo/index``)
- → AuditTheMath landing (``/action/audit-the-math/index``)
- → dung-beetle post (``/blog/posts/2026-05-21-prophetic-dung-beetle``)
- → b11 (PET) [foundational]
- → b19 (SGIR) [concrete example]
- → b18a appendix (Nobody's Job)

  *(coordination: launch-3 may have already added a subset of these
  inline; this prompt adds the remaining + the SI subsection.)*

**b19 (SGIR pandemic paper):**

- → Matheo overview (``/study/matheo/index``)
- → AuditTheMath landing (``/action/audit-the-math/index``)
- → b18a (Call to Action) [policy-action partner]
- → b21 (AI co-authorship framework) [used by this paper]

**Matheo overview** (``source/study/matheo/index.rst``):

- → Already cross-links to AuditTheMath + Buy-In per b20 §9.
- Verify these are still present after launch-1; add b18a +
  b19 entries with one-line descriptions if not present.

**AuditTheMath landing:**

- → Already cross-links to Matheo overview + Buy-In + dung-beetle
  per b20 §9.
- No additions needed; verify still present.

3. Tasks
==========

3.1 For each target paper, in order: b11 → b18a → b19
------------------------------------------------------

(a) Locate the paper's SI / Appendix section.

(b) Add (or update) a *"Related papers in the Matheo series"*
    subsection. Suggested heading text:

    *Related papers in the Matheo series*

(c) Populate the subsection with a list of ``:doc:`` links per
    §2 above. One-line description for each link, e.g.:

    *- :doc:`Matheo-b11 (PET) </matheology/hell/mm/b/11/...>`
    --- the Pan-En-Theology core axioms paper.*

(d) Where the paper's main text mentions the linked target by
    name on first occurrence, add an inline ``:doc:`` link.
    Use the L-B18A-3 / L-B18A-4 / L-B18A-5 patterns from
    b20 §5.4 as template.

3.2 Test
----------

After all P-1 links are inserted:

- ``make dev`` from repo root.
- 0 new warnings introduced.
- Click-through each new link in HTML build.
- For each paper, verify the new "Related papers" subsection is
  in the table of contents at the correct level (likely h2 or
  h3 inside SI / Appendix).

3.3 Cross-check
-----------------

The P-1 grid is symmetric in principle (if b11 → b18a, then
b18a → b11 should also exist). After all insertions, verify
symmetry. Asymmetries: report in llog, do NOT force-fix in this
session.


----

4. Out of scope
==================

- P-2 tier (full N×N grid across b11--b21) --- launch-7.
- P-3 tier (b18-esc + b21) --- launch-7.
- The 3 critical inline links from launch-3 (already added by
  launch-3; this prompt only adds the surrounding grid).
- Any paper outside the b11 / b18a / b19 set in this prompt's
  scope.
- Rewriting the SI / Appendix structure (TELES-scope insertion
  of a new subsection only).
- Generating one-line descriptions that are aspirational rather
  than factual --- use the paper's actual title + one
  factual-tone sentence.


----

5. Deliverables
=================

Produce a **single new LLog file** at
``source/matheology/hell/ll/infra/b/NN/bNN-launch-4-execution_<date>.rst``
containing:

- For each of the 3 target papers (b11, b18a, b19): file:line of
  each new link + before/after excerpt of the surrounding
  context.
- Symmetry check report.
- Build test result.
- Click-through test result.
- Concluding summary: which P-1 links are now in place + a
  pointer to launch-7 for P-2 / P-3 work.

Also update the infra index.


----

6. Timing & BABL-resistance
==============================

**Target: 60--90 minutes.**

The BABL trap: *over-Reaching* into P-2 territory. It is
tempting to "while I'm here, also add b12 → b13" or "also link
b15 → b16" --- **do not**. The P-1 / P-2 / P-3 prioritisation
exists to keep this prompt bounded. Drift into P-2 turns this
session into the full-grid session, and the launch slips.
