DonchitosandClaude Opus 5.5 b21fa0f7f2 Release 1.1.2 — the default path works end to end
Fix release for 1.1.1: the minimal path end to end, engine commands that
run on Godot, Unity and Unreal, hook warnings you can see, and verdicts
that say when they could not check. Details in CHANGELOG.md; upgrade
steps in UPGRADING.md (v1.1.1 → v1.1.2).

Fixes #67

# --- work from the project root ----------------------------------------------
# Every path below is repo-relative, so a hook invoked with a working directory
# that is not the repo root would silently read and write the WRONG TREE --
# returning a near-empty result instead of the session-recovery block, and
# creating stray trees such as docs/production/session-logs/ on write.
#
# PRECEDENCE IS LOAD-BEARING. A cwd that IS a project root carries real
# information and must win: a caller sitting inside another project means that
# project, not this one. Resolving to the script's own location first would
# override them. So, in order:
# 1. cwd holds project.yaml -> cwd (a project root)
# 2. cwd holds .claude/ -> cwd (a project root not yet configured)
# 3. CLAUDE_PROJECT_DIR -> that (populated in the hook environment)
# 4. this script's location -> <root>/.claude/hooks/../.. by construction
# Rule 4 always works and needs no environment at all; rules 1-2 stop it from
# overriding a caller that legitimately means somewhere else.
#
# NOT an upward search: that resolves a nested project to its parent's config.
