Bug: bd dep tree does not traverse 'blocks'-type dependency edges

Version

bd version 0.55.4

Description

bd dep tree <issue-id> always shows the root issue as [READY] with no children, even when bd dep list <issue-id> correctly shows blockers. The issue appears to be that dep tree does not traverse dependency edges stored as blocks relationships.

Steps to Reproduce

Given an issue with blockers (e.g. bd show reports it as blocked):

$ bd dep list myproject-abc

📋 myproject-abc depends on:

  myproject-x: Some blocker task [P2] (open) via blocks
  myproject-y: Another blocker [P2] (open) via blocks

$ bd dep tree myproject-abc

🌲 Dependency tree for myproject-abc:

myproject-abc: My Epic [P1] (open) [READY]

The tree shows no children despite the issue having blockers. Passing --type blocks explicitly makes no difference.

Root Cause (suspected)

dep list shows the relationships are stored as "via blocks" edges. It appears dep tree --direction=down traverses depends_on edges rather than blocks edges, so it finds nothing. bd graph <issue-id> works correctly for the same issue, suggesting it uses a more complete traversal.

Expected Behaviour

bd dep tree myproject-abc should show the same blockers that bd dep list myproject-abc shows, laid out as a tree.

Workaround

Use bd graph <issue-id> --compact instead — it correctly shows the full dependency structure.

[FergusFettes]

Update: The workaround listed above is incorrect — bd graph <issue-id> (and --box, --dot) also fail to traverse blocks-type edges, showing the epic in isolation with 0 deps. Same root cause as dep tree.

The only mode that correctly traverses the graph is bd graph --all. The actual workaround is to use bd graph --all --compact and filter the output to the section containing the issue of interest:

bd graph --all --compact | awk -v pat="projects-4lm" '
  /^────/ { if (keep) printf "%s", buf; keep=0; buf=""; next }
  { buf = buf $0 "\n" }
  $0 ~ pat { keep=1 }
  END { if (keep) printf "%s", buf }
'

So the scope of the bug is broader than originally reported: bd graph <id> and bd dep tree <id> both fail to traverse blocks-type edges — it's not just dep tree.
