# OH1 walk-oracle capture runner (2026-09-02).
#
# Substitutes <LOG> and the <FRAMES> frame-count token into one of this
# directory's oh-capture-*.cdb.template files (or runs oh-recon.cdb
# unmodified, since it has no <FRAMES> token to fill), verifies the LIVE
# retail acclient.exe process actually pairs with our named-retail PDB
# (aborting on mismatch -- see claude-memory/project_retail_debugger.md and
# CLAUDE.md's "Retail debugger toolchain" section for why this matters: a
# 2015 C:\Turbine\Asheron's Call\acclient.exe build does NOT pair with
# refs/acclient.pdb, only the 2013 v11.4186 build does), then launches cdb
# in the BACKGROUND (non-blocking -- the operator needs the foreground to
# drive the retail client during the capture) with output redirected to a
# companion ".console" file next to -Log.
#
# NOTE: this script does NOT resolve every token some templates need.
# oh-capture-parts.cdb.template has two <GFXOBJ_DID_OFF> occurrences that
# are NOT substituted here (see that file's own OPEN QUESTION comment and
# the README) -- hand-edit those before pointing -Script at that template
# for a real session.
#
# Usage:
#   .\oh-run-capture.ps1 -Script oh-recon.cdb -Log C:\path\to\oh-recon.log
#   .\oh-run-capture.ps1 -Script oh-capture-walk.cdb.template `
#       -Log C:\path\to\holtburg-doorway-still.walk.log -Frames 5
#
# Then, in another shell (this script returns immediately):
#   Get-Content C:\path\to\holtburg-doorway-still.walk.log -Tail 50 -Wait
