docs: correct security and workspace status

[anandh8x]

Summary

• Correct the workspace inventory to include all crates.
• Align the README and security policy with the existing read-visibility controls and current authorization and review limitations.
• Update near-term documentation priorities to match the implementation.

Why

The public documentation described workspace contents and security behavior that no longer match the current code, which could lead operators and contributors to make incorrect assumptions.

Validation

• git diff --check
• cargo fmt --all -- --check
• Source review against the current authorization and visibility implementation
• cargo test --locked --workspace — 821 tests passed; two unchanged node tests failed in this environment, including when run in isolation after their 30-second test budgets.

Summary by CodeRabbit

• Documentation
  • Updated the README and contribution guide with the current workspace layout and repository/path-scoped read visibility.
  • Clarified security limitations and safeguards covering write authorization, UCAN trust and revocation, private reads, GraphQL mutations, and pull-request approvals.
  • Updated the maintainer roadmap with priorities for authorization, trusted delegation, metadata visibility, and irreversible publication.
  • Added a historical-snapshot notice to the open-source readiness audit and linked current security guidance.

📝 Walkthrough

Walkthrough

The PR updates repository documentation to describe six workspace crates, read visibility enforcement, UCAN validation and authorization limitations, current security boundaries, roadmap priorities, and the historical status of an OSS readiness audit.

[beardthelion]

The corrections here are real and I verified each one against main: six workspace crates, the signed JSON UCAN wire format, GITLAWB_ENFORCE_OWNER_PUSH defaulting false, capability grants not consulted by write authorization, revocation not checked at signature time, merges not enforcing approvals. The private-read section had genuinely gone stale and this is the right direction.

What holds the round is one deletion and three claims that are stronger than the code supports. All four are in the paragraph describing read enforcement, which is the part operators use to decide what is safe to host.

Findings

• [P1] Keep the warning against storing secrets on a public node
  SECURITY.md:75
  The read gate governs what this node serves, not what has already left it. A push to an announceable repo pins objects to IPFS/Pinata and anchors each ref update to Arweave, and there is no unpin or retraction path in the node source. announce is evaluated at push time in api/repos.rs:2489 and never re-evaluated, so tightening a repository's visibility afterwards does not retract what was already published. Replacing that warning with "Callers can read only repositories and paths their visibility rules permit" removes the only guidance covering the irreversible case.

• [P2] Scope the 404 sentence to repository existence, since withheld path globs are published
  SECURITY.md:74
withheld_paths in api/visibility.rs:209 runs the root read gate and then returns the denied globs themselves, and it is mounted with an optional auth extractor, so an anonymous caller on a public repo with a private subtree learns that subtree's name. That is deliberate, since sparse-clone clients need it. Repository existence is hidden; withheld-path existence is not, and an operator could reasonably read the current wording as license to put sensitive information in a directory name.

• [P2] Qualify the read-scope claim: three read surfaces take no caller and no visibility check
  SECURITY.md:75
GET /api/v1/tasks and GET /api/v1/tasks/{id} are mounted at server.rs:81-82 with no auth layer and no visibility check, and task_to_json at api/tasks.rs:83 serializes ucan_token, so an unauthenticated caller reads a credential. /api/v1/ipfs/pins and /api/v1/arweave/anchors are likewise ungated, and the anchors response carries repo, owner_did, ref_name and both SHAs. The comment at server.rs:216 already concedes the pin index gap. Worth naming these as a remaining boundary rather than stating the rule without exception.

• [P2] Reconcile the threat model with the new write-authorization text
  SECURITY.md:118
  "Unauthorized writes" still sits under "designed to be secure against" while the paragraph added at line 56 says the default does not require the pusher to be the repository owner. Scoping that bullet to authentication and pointing at Known Limitations would settle it. This one resolves itself if #330 lands first, but it contradicts the file as written today.

• [P3] Fix the UCAN row in the Cryptographic Primitives table
  SECURITY.md:111
  The table still reads JWT (Ed25519 signatures) while line 34 now says signed JSON. Ucan::encode is serde_json::to_string and the signature is a base64url field inside the JSON object, so the new prose is right and the table is the half to change. CodeRabbit flagged the conflict without picking a direction; the code picks it.

• [P3] Carry the correction into the two other docs that still assert the old state
  CONTRIBUTING.md:29-35, docs/MAINTAINER-ROADMAP.md:42
  CONTRIBUTING still draws a four-crate tree with no gitlawb-attest or icaptcha-client, and line 109 still asks for help completing UCAN chain validation. The roadmap carries verbatim the sentence this PR deletes from the README, under its own principle that every public claim in docs should match current behavior. docs/OSS-READINESS-AUDIT.md:93 says the same thing but reads as a dated snapshot, so a superseded note is enough there.

Separately, config.rs:58 and the startup warning at main.rs:87 both still say per-repo read enforcement is not wired, which now contradicts this PR directly. An operator who sets GITLAWB_PUBLIC_READ=false after reading the new text gets told by the node that the feature does not exist. That is a code change rather than a docs one, so please open a follow-up for it rather than pulling it in here.

On ordering: #330 and #331 both touch README.md and each one invalidates a paragraph this PR adds, so landing this first and rebasing their README hunks onto it is the cheaper direction.

Superseded: this review was on e6fd386, which is no longer in the branch history. Re-reviewed at 0b47e1f.

[beardthelion]

All six findings from the last round are addressed at 0b47e1fc, and I checked each corrected claim against the code rather than against the prose. The irreversibility warning is back and scoped correctly, the 404 sentence is now limited to repository existence, the withheld-path caveat matches what withheld_paths actually returns to a caller who can read the root, and the three ungated metadata routes are named with the UCAN exposure called out. The threat-model bullet reads "unauthenticated" now, the primitives table says signed JSON, and the crate-count and UCAN corrections carried into CONTRIBUTING and the roadmap with a dated-snapshot note on the OSS audit.

One follow-up from last round is still open and stays out of this PR: config.rs:58 and the startup warning in main.rs:87 both still say per-repository read enforcement is not wired, which this PR now contradicts. Please open an issue for it so it does not get lost.

Worth noting the full CI suite has not executed on this head (fork approval gate), so the checks showing green are triage only. I will approve the run before merging.
