What

Applies the owner ruling (2026-09-02): MPL-2.0 for code, CC-BY-SA-4.0 for docs — answering the licence-identity question flagged in #76 (comment: MPL-2.0 SPDX headers over PALIMPSEST-MPL bodies, template-wide).

Ruling applied as: SPDX headers were already correct; the PMPL licence bodies and prose declarations were the defect. LICENSE bodies become plain MPL-2.0, PMPL texts and declarations are removed, documentation stays CC-BY-SA-4.0.

Changes

  • 7 component LICENSE files → canonical MPL-2.0 text (from LICENSES/MPL-2.0.txt); vexometer-efficacy gains its missing LICENSE (was the only component without one)
  • Deleted: {satellite-template,verbosity-compressor,vexometer}/license/PMPL-1.0.txt, vext/PALIMPSEST.adoc (declared PMPL-1.0 as governing; no inbound links)
  • NOTICE rewritten to the ruled identity
  • guix.scm: (license (@ (guix licenses) mpl2.0)) — the old two-arg private-constructor call was arity-broken if ever evaluated, and pointed at the palimpsest repo
  • Badges/sections: READMEs of vexometer, vext, vexometer-satellites, lazy-eliminator, verbosity-compressor, satellite-template (placeholders preserved); QUICKSTART-MAINTAINER; vext RSR_COMPLIANCE + TECHNOLOGY_STACK
  • Generators: vext/COMMIT-AND-PUSH.sh heredoc no longer writes a PMPL LICENSE; setup-repo.k9.ncl example no longer curls one from hyperpolymath/pmpl
  • Trust manifests: all 8 regenerated (just trust-verify passes) — READMEs are tracked inputs

Deliberately untouched

  • Historical records: vext/CHANGELOG.adoc, vext/docs/conference-materials.adoc (they record what was)
  • vext/.well-known/ai.txt line 34 — Philosophy pointer, not a licence claim
  • Gate accept-patterns in contractile.just:65 / root Trustfile.a2ml:57 keep a now-dead PMPL alternative in their grep alternations — harmless residue, flagging rather than touching gate code here

Debt observed (not fixed here)

  • vext/COMMIT-AND-PUSH.sh is legacy-and-dangerous independent of licensing: copies from broken /var$HOME/... paths (same scar class as the estate /var$REPOS_DIR bug) and would clobber vext's LICENSE/CONTRIBUTING/SECURITY if ever run. Deletion candidate — owner call.
  • vext/vext-core/Cargo.toml:84 license-file points at nonexistent ../LICENSE.txt
  • Estate-wide: PMPL bodies likely exist in other repos; sweeping beyond vexometer is a separate owner decision

Closes the licence-identity question from #76.

… docs

SPDX headers were already correct; the licence *bodies* and prose
declarations were the defect: component LICENSE files carried the
PALIMPSEST-MPL "PMPL-1.0" text under an MPL-2.0 SPDX header.

- Replace all 7 component LICENSE files with the canonical MPL-2.0 text
  (LICENSES/MPL-2.0.txt); add the missing vexometer-efficacy/LICENSE
- Delete license/PMPL-1.0.txt (x3) and vext/PALIMPSEST.adoc
- Rewrite NOTICE to the ruled identity; fix guix.scm to the standard
  (@ (guix licenses) mpl2.0) form (old 2-arg constructor was arity-broken)
- Fix licence badges/sections in 6 READMEs, QUICKSTART-MAINTAINER,
  vext RSR_COMPLIANCE + TECHNOLOGY_STACK, the COMMIT-AND-PUSH.sh heredoc,
  and the setup-repo.k9.ncl example (curled a PMPL LICENSE for new repos)
- Regenerate all 8 trust manifests (READMEs are tracked inputs)

Historical records (vext CHANGELOG, conference-materials) left untouched.

📝 Summary

Summary by CodeRabbit

  • Documentation

    • Updated project documentation and licence badges to reflect MPL-2.0 for code and CC-BY-SA-4.0 for documentation.
    • Replaced custom licence text with the standard Mozilla Public License 2.0.
    • Updated licence references and generated licence instructions across project templates.
  • Chores

    • Added standard MPL-2.0 licensing to projects previously lacking a local licence file.
    • Regenerated trust manifests to reflect updated documentation content.

Walkthrough

The change replaces Palimpsest-MPL references with standard MPL-2.0 licensing. Documentation is licensed under CC-BY-SA-4.0. Component licence files, package metadata, README files, compliance records, and trust manifests were updated.

Changes

Licensing standardisation

Layer / File(s) Summary
Repository licensing contracts
.machine_readable/..., NOTICE, QUICKSTART-MAINTAINER.adoc, guix.scm, vext/COMMIT-AND-PUSH.sh
Repository licence declarations, package metadata, setup recipes, and generated licence output now use MPL-2.0.
Component licence files
lazy-eliminator/LICENSE, satellite-template/LICENSE, verbosity-compressor/LICENSE, vexometer-efficacy/LICENSE, vexometer-satellites/LICENSE, vexometer/LICENSE, vext-email-gateway/LICENSE, vext/LICENSE
The custom Palimpsest-MPL text was replaced with the standard Mozilla Public License Version 2.0 text.
Documentation and integrity records
*/README.adoc, vext/RSR_COMPLIANCE.adoc, vext/TECHNOLOGY_STACK.adoc, */.trust/trust-manifest.sha256
Documentation now identifies MPL-2.0 code and CC-BY-SA-4.0 documentation. Licence badges link to local licence files. Trust manifests were regenerated where README content changed.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 5047c

The licensing migration is not yet merge-ready because generated repositories may receive incomplete or falsely successful LICENSE files, while repository notices, compliance records, and README declarations can still misstate the applicable licenses. These issues could propagate incorrect licensing metadata and require correction before merging.

Inline comments:
In @.machine_readable/self-validating/examples/setup-repo.k9.ncl:
- Line 135: Update the license download command in the setup recipe to use
curl’s --fail, --show-error, and --location options, write the response to a
temporary file, and replace LICENSE only after a successful download.

In `@NOTICE`:
- Around line 15-16: Update the licensing statement in NOTICE to accurately
describe SPDX headers as appearing in a format-permitted position rather than
universally on line 1, unless the K9 format supports moving the declaration and
the example file can be made conformant.

In `@satellite-template/README.adoc`:
- Around line 5-7: Complete the README licence migration: update
satellite-template/README.adoc lines 5-7 to state the MPL-2.0 code and
CC-BY-SA-4.0 documentation split and reference LICENSE instead of LICENSE.txt;
update lazy-eliminator/README.adoc line 6 and vexometer-satellites/README.adoc
line 11 to state the same code/documentation licence split.

In `@vexometer/.trust/trust-manifest.sha256`:
- Line 1: Add the required SPDX-License-Identifier header for MPL-2.0 to the
trust-manifest file in a position supported by the trust-manifest format, while
preserving the existing manifest content.

In `@vext/COMMIT-AND-PUSH.sh`:
- Line 30: Update the LICENSE heredoc in the repository-generation script so it
writes the complete canonical Mozilla Public License 2.0 text, using a
checked-in canonical source or a failure-checked, verified fetch; retain the
generated LICENSE creation flow and ensure incomplete placeholder content is no
longer emitted.

In `@vext/RSR_COMPLIANCE.adoc`:
- Around line 127-129: Update Appendix B in RSR_COMPLIANCE.adoc so its SPDX
evidence lists MPL-2.0 for source code files and CC-BY-SA-4.0 for documentation
files, replacing the statement that all source files use CC-BY-SA-4.0; keep the
evidence aligned with the dual-licensing section.

Generate the complete canonical MPL-2.0 text.

The heredoc creates LICENSE, but it contains only a title, a short notice, a URL, and an SPDX identifier. It does not contain the canonical MPL-2.0 text required by this rollout.

A repository generated by this script can therefore receive an incomplete LICENSE. Generate the full canonical text from a checked-in source, or fetch it with failure checking and verification.

This follows the PR objective that generated repositories receive canonical MPL-2.0 text.

CodeRabbit triage (commit e2c5631):

Fixed (4):

  • setup-repo.k9.ncl curl fail-open — now curl -fsSL writing to a temp file first; an HTTP error can no longer leave an error body as LICENSE
  • NOTICE SPDX-position claim — now "line 1, or the first line the format permits" (K9 files carry K9! on line 1, SPDX on line 2)
  • Incomplete README migration — later == License sections in satellite-template (incl. dead LICENSE.txt link), lazy-eliminator, vexometer-satellites now state the MPL-2.0 code / CC-BY-SA-4.0 docs split
  • RSR_COMPLIANCE Appendix B — SPDX evidence split by file type (was: all source files CC-BY-SA-4.0)

Skipped (2), with reasons:

  • SPDX header on .trust/trust-manifest.sha256 — generated artifact written by scripts/trust/generate-manifest.sh in pure sha256 path format; a header line would be clobbered on next regen and break hash-format parsing. Convention across all 8 manifests, gates green.
  • Full canonical MPL-2.0 text in the COMMIT-AND-PUSH.sh heredoc — the script is a legacy deletion candidate (see PR body: broken /var$HOME paths, clobbers vext files if run). The pointer-form notice with SPDX id + canonical URL matches MPL-2.0's own Exhibit A practice. Not worth a heavy lift on a script slated for removal — owner call on deletion.

Follow-up to #78 (owner ruling: **MPL-2.0 for code, CC-BY-SA-4.0 for
docs**). Clears the four residue items fenced in the #78 report, all
owner-approved:

- **Delete `vext/COMMIT-AND-PUSH.sh`** — legacy one-shot bootstrap
script with broken `/var$REPOS_DIR` / `/var$HOME` paths, superseded by
the monorepo. `grep -rn 'COMMIT-AND-PUSH'` proves no inbound references.
- **Fix `vext/vext-core/Cargo.toml` cargo-deb pointer** — `license-file`
pointed at `../LICENSE.txt`, which never existed; now `../LICENSE`
(canonical MPL-2.0 since #78). `[package] license = "MPL-2.0"` was
already correct and is untouched.
- **Drop the dead `PMPL` alternative** from the licence-content accept
patterns in `contractile.just:65` and
`.machine_readable/contractiles/Trustfile.a2ml:57`. Behaviour-neutral
(`MPL` substring-matched `PMPL` anyway); the patterns now name only
licences that can actually appear.

Verification: `just trust-verify` and `just trust-manifest-verify` both
pass locally; all 8 component manifests verify unchanged, so no regen is
required (neither gate file is manifest-tracked). No `uses:` refs
touched, so actions.lock is untouched per the standing contract.
