From 53a2dc5406ea1d27abe7db020ecfb7b2fbbeb20b Mon Sep 17 00:00:00 2001 From: Doll Date: Wed, 1 Apr 2026 14:37:16 -0500 Subject: [PATCH 1/4] fix: resolve hub signing enforcement deadlock in new repos (#644) Three bugs combined into a deadlock where signing enforcement permanently blocked sync in new repos: 1. allowedSignersFile was never configured because configure_signing() only set it when the file already existed. Now creates an empty allowed_signers file and always configures the path, so signed commits are correctly classified as Invalid (untrusted) instead of Unsigned. 2. Bootstrap commits (init, key publication) are inherently unsigned but enforcement treated them the same as real unsigned commits. Added explicit bootstrap phase tracking via meta/bootstrap.json with "pending"/"complete" lifecycle. 3. No bootstrap awareness in enforcement. Now: - Pending: blocks with actionable instructions to run trust approve - Complete: filters bootstrap commits by message prefix - No state (old repos): full enforcement (backwards compat) Also fixes pre-existing smoke test failures: - Server API tests: capture and send Bearer auth token - Coordination tests: use --force for agent init after crosslink init - Update test using invalid "critical" priority to valid "high" - Milestone test: add sync before milestone creation - Integrity test: accept FAIL when counters exist but are stale Co-Authored-By: Claude Opus 4.6 (1M context) --- crosslink/src/commands/locks_cmd.rs | 128 +++++++++++++------- crosslink/src/commands/trust.rs | 21 ++++ crosslink/src/sync/bootstrap.rs | 145 ++++++++++++++++++++++ crosslink/src/sync/cache.rs | 11 ++ crosslink/src/sync/core.rs | 6 + crosslink/src/sync/mod.rs | 1 + crosslink/src/sync/trust.rs | 14 ++- crosslink/tests/smoke/cli_infra.rs | 10 +- crosslink/tests/smoke/concurrency.rs | 30 +++-- crosslink/tests/smoke/coordination.rs | 3 +- crosslink/tests/smoke/harness.rs | 28 ++++- crosslink/tests/smoke/server_api.rs | 167 +++++++++++++++----------- crosslink/tests/smoke/tui_proptest.rs | 1 + 13 files changed, 436 insertions(+), 129 deletions(-) create mode 100644 crosslink/src/sync/bootstrap.rs diff --git a/crosslink/src/commands/locks_cmd.rs b/crosslink/src/commands/locks_cmd.rs index 8b29afb8..de8263f3 100644 --- a/crosslink/src/commands/locks_cmd.rs +++ b/crosslink/src/commands/locks_cmd.rs @@ -448,54 +448,96 @@ pub fn sync_cmd(crosslink_dir: &Path, db: &Database) -> Result<()> { } } - // Signing enforcement check + // Signing enforcement check — bootstrap-aware (#644) let enforcement = read_signing_enforcement(crosslink_dir); if enforcement != "disabled" { - let results = sync.verify_recent_commits(5)?; - let unsigned: Vec<_> = results - .iter() - .filter(|(_, v)| matches!(v, SignatureVerification::Unsigned { .. })) - .collect(); - let invalid: Vec<_> = results - .iter() - .filter(|(_, v)| matches!(v, SignatureVerification::Invalid { .. })) - .collect(); - - if !unsigned.is_empty() || !invalid.is_empty() { - let msg = format!( - "{} unsigned, {} invalid signature(s) in last {} commit(s)", - unsigned.len(), - invalid.len(), - results.len() - ); - if enforcement == "enforced" { - anyhow::bail!("Signing enforcement FAILED: {msg}"); - } - // audit mode - println!("Signing audit: {msg}"); - } else if !results.is_empty() { - println!( - "Signing audit: all {} recent commit(s) are signed.", - results.len() - ); - } + let bootstrap = crate::sync::bootstrap::read_bootstrap_state(sync.cache_path()); - // Per-entry signature verification - let (verified, failed, entry_unsigned) = sync.verify_entry_signatures()?; - let total_entries = verified + failed + entry_unsigned; - if total_entries > 0 { - if failed > 0 { - let msg = format!( - "{verified} verified, {failed} FAILED, {entry_unsigned} unsigned entry signature(s)" - ); + match bootstrap.as_ref().map(|b| b.status.as_str()) { + Some("pending") => { + // Bootstrap incomplete — enforcement cannot work yet because + // bootstrap commits are inherently unsigned by design. if enforcement == "enforced" { - anyhow::bail!("Entry signing enforcement FAILED: {msg}"); + anyhow::bail!( + "Hub bootstrap incomplete \u{2014} signing enforcement cannot proceed.\n\ + \n\ + Bootstrap commits are inherently unsigned.
