Summary

Two operator-facing docs contradicted the code's GITLAWB_ENFORCE_OWNER_PUSH default: Config::enforce_owner_push declares default_value_t = true, .env.example sets =true, and the README env-var table agrees, but SECURITY.md and the README known-limitations prose both still said the default was false. This corrects both docs and adds a parity test that reads the surfaces off the working tree so a future doc regression goes red.

Continues #383 by @Gravirei (the commits are carried over unchanged; main was merged in as a separate commit).

Motivation & context

Operator-facing surfaces were lying about the authorization policy in opposite directions. A reader of SECURITY.md or the known-limitations bullet would believe owner enforcement is opt-in when it is on by default.

Kind of change

• Bug fix
• Feature
• Security fix
• Docs
• Tests / CI
• Refactor (no behavior change)
• Breaking or protocol change (issue required first)

What changed

• SECURITY.md: the owner-push limitation now leads with "defaults to true" and describes GITLAWB_ENFORCE_OWNER_PUSH=false as the explicit rolling-upgrade compatibility override.
• README.md: same correction in the known-limitations bullet.
• crates/gitlawb-node/tests/owner_push_default_docs.rs: new regression test asserting each of the four surfaces (SECURITY.md section, README prose, README env-var row, .env.example) independently says the default is true. Reverting either doc edit turns the named test red.

How a reviewer can verify

cargo test -p gitlawb-node --test owner_push_default_docs

On the pre-fix tree the two corrected surfaces fail the parity checks: SECURITY.md and the README known-limitations bullet still claimed false (re-verified on the merge-base, which fails the two named tests; the env-var row and .env.example were already correct and stayed green).

Before you request review

• Scope is one logical change; no unrelated churn
• cargo test -p gitlawb-node passes locally
• New behavior is covered by tests (required for fixes)
• cargo fmt --all and cargo clippy --workspace --all-targets -- -D warnings are clean
• Commit titles use Conventional Commits (feat(...), fix(...), docs(...))
• Docs / .env.example updated if behavior or config changed (this PR is the doc correction)
• Checked existing PRs so this isn't a duplicate (issue-26 splits fix(node): durable post-receive outbox for receive-pack (#26 split 1/4) #384 and fix(node): version ref_certificates for forward compat (#26 split 3/4) #386 share doc files but carry no overlapping prose change)

Protocol & signing impact

None: documentation and a test that reads repo files at test time only.

• Touches DID / did:key, Ed25519 / RFC 9421 signatures, UCAN, ref certs, or P2P wire formats
• Discussed in an issue before implementation
• Backward-compatible with existing nodes and previously signed history

Notes for reviewers

Part of the issue-26 split series (split 4 of 4: configuration and operator policy). Safe to land independently of the siblings.

I ran the gitlawb-node suite, not the whole workspace.

Summary by CodeRabbit

• Documentation
  • Clarified that owner-only push enforcement is enabled by default: signed pushes require the caller to own the repository.
  • Documented that disabling enforcement is a temporary rolling-upgrade option that allows any signed caller to push to any repository, including private ones.
  • Clarified that signatures authenticate callers but do not authorize repository writes, and delegated or CI keys cannot push while enforcement is enabled because push capabilities are not used for authorization.
• Tests
  • Added checks that the documented default and example configuration remain consistent.

Walkthrough

The documentation states that GITLAWB_ENFORCE_OWNER_PUSH defaults to true and describes a temporary override for rolling upgrades. Integration tests check the setting in SECURITY.md, README.md, and .env.example.

Changes: Owner-Push Default Documentation

Layer / File(s)	Summary
Document the owner-push policy README.md, SECURITY.md	The documentation states that owner-push enforcement defaults to true. It describes the temporary upgrade override, notes that signatures alone do not authorize pushes, and describes the limits on delegated and CI keys. The README roadmap now lists trusted UCAN delegation for repository write authorization.
Check documented defaults crates/gitlawb-node/tests/owner_push_default_docs.rs	Integration tests check the documented default in SECURITY.md and README.md, and check that .env.example sets the value to true. They also reject specified false-default claims.

Merge Risk: Minimal · up to 94b87

This change corrects documentation to state that owner-push enforcement defaults to true and adds tests that check the documented default. It does not change runtime behavior, so merge risk is minimal.

Tie the SECURITY.md default claim to the variable.

The check can pass if the default sentence no longer names GITLAWB_ENFORCE_OWNER_PUSH. Match the variable and the default together.

Merge readiness

Please update the PR branch to include the current main tip 5ed3381 (e.g. merge or rebase from origin/main). At review time the branch head 35a4443 did not contain that tip (HEAD..origin/main listed 5ed3381; merge-base --is-ancestor origin/main HEAD failed). Confirm required checks on the updated head before merge.

README Roadmap vs Known limitations — contradictory “default-open” wording

Where: README.md — Known limitations (first bullet) vs Roadmap → Short-term priorities item 5.

What fails: Operators reading both sections see two incompatible stories:

• Known limitations (as updated by this PR) say GITLAWB_ENFORCE_OWNER_PUSH defaults to true and frame repository write authorization as secure by default (with false only as a rolling-upgrade escape hatch).
• Roadmap item 5 is unchanged and still says: “Close default-open write authorization and wire trusted UCAN delegation into repository permissions.”

That roadmap line matched the old limitation text when the default was documented as false. After this PR, it reads like pushes are still default-open, unless the reader narrows “default-open” to UCAN/collaboration-only gaps.

Root cause: Known limitations and SECURITY.md were updated, but sibling operator copy in the same README (Roadmap) still uses the old framing.

Required correction: Edit roadmap item 5 (and surrounding context if needed) so it does not imply default-open HTTP-signed repository write authorization in the sense this PR corrected. Align wording with Known limitations / SECURITY.md: owner enforcement on by default; rolling-upgrade override; UCAN git/push verified but not yet honored for authorization; remaining work is wiring trusted delegation/capabilities into write auth, not flipping the default from open to closed.

Out of scope: No need to change runtime defaults, implement UCAN delegation, or expand owner_push_default_docs unless you want an extra guard — a prose fix is enough.

Needs maintainer decision: None from this review.

[beardthelion]

Both addressed at 94b870e: the branch now merges origin/main at 5ed3381, and roadmap item 5 no longer claims writes are default-open; it reads 'Wire trusted UCAN delegation into repository write authorization.' Doc-parity suite is green at this head (4/4).

[jatmn]

Merge readiness

The branch head includes main (merge base 5ed3381), and the earlier roadmap vs known-limitations inconsistency is resolved on the current head (roadmap item 5 no longer implies default-open HTTP write auth in conflict with the updated limitations). Please confirm the PR Checks tab on the head you merge.

---

🟢 Approve — No actionable issues from this review. Documentation matches the GITLAWB_ENFORCE_OWNER_PUSH default, parity tests pass, and the README/SECURITY/roadmap story is aligned.

Needs maintainer decision: None.
