# Takeover 21113 friction

FRICTION:
forge | gh pr edit assignment failed on deprecated classic Projects GraphQL field; targeted assignee API write succeeded | update gh or use the narrow assignee write
forge | GitHub PR creation initially could not see the newly pushed GitCafe branch; creation succeeded after mirror visibility | wait for mirrored ref visibility before gh pr create
runbook | original coordinator patch conflicted with newer main PR-link implementation during revert proof | port the three intended edits onto current API and preserve existing tests
runbook | first proof matrix confused start/end diffs with zero/stated-threshold diffs and required unrelated invariant captures | define same-checkpoint comparisons and affected-only mandatory rows
runbook | numeric DEV_INSTANCE is a port offset; oversized values exhausted valid ports on initial attempts | document bounded known offsets
runbook | multi-environment ambiguity needs three identities; newest-thread prompt selection needs a persisted stopped thread; bridge delivery needs a labeled harness | publish exact seed drivers and distinguish actual runtime from harness
policy | working product preview is headless at DPR2 and cannot satisfy required ffmpeg X11 captures; switching automation is forbidden without explicit workflow authorization, which remains unanswered | provide or explicitly authorize a headed Xvfb capture workflow
policy | this task is a delegated child, and app orchestration forbids child PR watches | parent owns any further watch or monitoring
infra | primary identity swaps on a shared browser origin retained fixture auth/cache and old remotes, delaying welcome setup | use real pairing and remove/re-pair fixture remotes; explicitly reset equivalent browser state
tool | preview evaluate rejected leading/trailing whitespace and a role locator did not support exact attribute | trim scripts and use snapshot refs/supported locator syntax
tool | a guessed preview_close tool name did not exist; discovered t3_preview_close succeeded | discover exact callable tool metadata before invoking
tool | nonincremental typecheck conflicted with composite mode during read-only review | disable both composite and incremental
tool | missing-file ls and combined-check output obscured command exit provenance | run scoped commands independently and inspect each result
other | supplied original head is already a maintainer-authored takeover commit, not exclusively contributor code | pin proof to explicitly verified before/after objects and preserve attribution limits
other | proof audit found folder-failure image caption claimed a toast not visible in the PNG | corrected and republished the evidence index; keep frame claims narrower than runtime observations
