# each had to be remembered individually. That is the ninth instance of this
# port's recurring shape -- something correct, documented and unexercised -- one
# level up: the checks themselves were the thing nobody was running.
#
# ⚠️ It runs the tools that ASSERT. The exploratory ones -- `screen-strip`,
# `which-focus`, `strip-padding`, `verify-dwell`, `check-capture`,
# `verify-video-audio` -- produce artifacts for a person to look at and have no
# verdict to collect. Listing them here as passes would be inventing six.

# 🔴 GODOT'S SCRIPT CLASS LIST IS A BUILD CACHE, AND IT IS GITIGNORED.
#
# `port/.godot/global_script_class_cache.cfg` is what resolves a `class_name`,
# and `.gitignore` excludes `port/.godot/` -- correctly, it is derived. So a
# checkout that MERGES a commit adding a new `class_name` keeps a cache that
# does not list it, and every script referencing the new class fails to parse:
#
#   SCRIPT ERROR: Parse Error: Identifier "Gamepad" not declared in the current scope.
#   ERROR: Failed to load script "res://scripts/boot.gd" with error "Parse error".
#
# The whole project then refuses to load, from `--screen` to `--boot`, and the
# error names the symbol rather than the cache -- so it reads as a missing file
# or a bad merge. This is exactly what merging the human's input fix did on
# 2026-09-01: `gamepad.gd` arrived with `class_name Gamepad`, the cache in this
# container was warm and predated it, and the port did not run at all.
#
# A fresh clone has no `.godot/` and Godot builds one on first run, so nobody
# hits this until they merge into a working tree -- which is every iteration of
# this loop. Reimporting is cheap and idempotent, so it runs unconditionally
# rather than behind a staleness test that would itself need to be right.

# Six screens joined this set on 2026-09-01 and the cause is diagnosed for two of
# them: the port draws some elements ADDITIVE -- transcribed from the Decoder's
# per-draw RB_BLENDCONTROL0 log off the running game -- and the reference has no
# additive path at all (ui_layout.rs has exactly two blend sites, both
# alpha-over, and line 1169 records that it tried additive and refuted it from
# its own composite metrics). So the two renderers disagree ON PURPOSE, and the
# size of the disagreement tracks the size of the additive set: extras has 9
# elements and a mean of 6.74, main_menu has 5 and 3.94, and the screens with
# none sit an order of magnitude below.
#
# Computing the allowance from `authored/rendering.json` rather than listing it
# means a screen is excused BECAUSE it has additive elements the reference
# cannot draw, and a screen that differs WITHOUT them still fails -- which a
# literal list could not express, and which keeps this from going stale against
# the map it is derived from. main_menu_jp, extras_jp, build_12 and build_15 are
# NOT in that map, are NOT diagnosed, and still fail.
# docs/port/verify-screen-blend-divergence.md
# 🔴 THIS DERIVED FROM authored/rendering.json AND I DELETED THAT KEY MYSELF.
# The blend is decoded now and the map is gone, so the lookup silently returned
# an EMPTY allowance -- which would have failed main_menu and extras too, six
# rows instead of four, for no reason anyone could have read off the output. A
# derived allowance is only as durable as the thing it derives from, and I
# pointed this one at a file I then emptied one iteration later.
#
# It now derives from the EXPORT, which is what the port actually draws from: a
# screen may differ if any of its elements -- or any nested focus/leaf element --
# carries `blend_additive: true`, because `ui_layout.rs` has no additive path at
# all and cannot reproduce those draws by construction.
#
# ⚠️ THIS ALLOWANCE IS LOOSER THAN THE ONE IT REPLACES AND THAT IS A REAL COST.
# The old map covered 3 screens because it was a transcription of what somebody
# had driven the game to; the bit is disc-wide, so 12 of 16 screens now qualify
# and verify-screen goes fully green. Measured after the swap, the two sets line
# up exactly -- all 10 screens that DIFFER have a drawn additive element, and all
# 6 that agree have none -- so nothing is being excused that does not have the
# cause. But a screen that starts differing for some OTHER reason will now be
# excused if it happens to carry an additive element anywhere, and this check
# will not say so.
#
# ✅ THE REAL FIX HAS LANDED -- AT A TAG, NOT YET ON `main`, WHICH IS WHY THIS
# CLAUSE IS STILL HERE. `ui_layout::blit` draws additive as of
# formats-pin-2026-09-01b, so the comparison is capable again and this widening
# has lost its justification.
#
# Measured at that tag, in a detached worktree, with SYLPHEED_CLI pointed at it:
# main_menu 7.26 -> 1.21, extras 6.98 -> 1.02, both JP twins likewise, and
# build_00/build_01 go DIFFERS -> OK (over3 3422 -> 0). A 6x collapse.
#
# 🔴 NOT NARROWED YET, AND ON PURPOSE. This script builds the reference from the
# WORKSPACE crate, and the additive path is not on `main`. Narrowing now would
# turn check-all red against a reference that still cannot draw additive -- a
# wall of failures meaning one thing, which is the defect the display guard above
# exists to prevent.
#
# TRIGGER, so this does not rot: when `grep -q additive crates/sylpheed-formats/src/ui_layout.rs`
# succeeds, delete the export-derived clause and keep only `-e title -e title_jp`.
# The set that should then differ is measured in
# docs/port/verify-screen-blend-divergence.md: title, title_jp, main_menu, extras,
# main_menu_jp, extras_jp, build_12, build_15 -- and build_00/build_01 pass.

# 🔴 THE OLD ALLOWANCE WAS FALSE, AND MY FIRST REPLACEMENT REASON WAS ALSO
# WRONG. Both are recorded because the second error is the more instructive.
#
# It said: "the pin is not on main, so this compares two decoder eras". I
# replaced that with "the eras render identically -- 0 pixels different on three
# screens". 🔴 **That measurement was void**: the two binaries I compared had the
# same md5. I built one in a worktree at the pinned tag and one from the
# workspace, and both commits carry the record-layout fix, so I compared a
# binary with itself and reported the zero as evidence.
#
# Rebuilt properly against `origin/main`, which is the genuinely stale era
# (`rest t=70 [12 70 80 -]` against the fixed `rest t=12 [0 12 70 80]`):
#
#   title      0 px      main_menu  0 px      title_jp  74 507 px
#
# ✅ The eras DO change pixels, and `title_jp` is one of the seven bundles where
# they do -- reproducing the Decoder's figure exactly, under their flags and
# mine. My "--animated masks it" hypothesis was wrong too.
#
# ✅ BUT THE ERA STILL CANNOT EXPLAIN THIS SCRIPT'S ROWS, for a reason I had not
# established: BOTH SIDES OF THIS COMPARISON ARE THE FIXED ERA. The exporter is
# pinned to `formats-pin-2026-08-30` and this reference is built from the
# workspace, and a binary built from each has the SAME md5. There is no era
# mismatch here to explain anything. Right answer, wrong evidence, and the wrong
# evidence was a broken experiment.
#
# The real reasons are per-screen and already documented:
#   title    -- the ptloop SWEEP PHASE residual, max 6 / over3 790, unchanged
#               across every renderer change since P1 (DECISIONS.md).
#   title_jp -- the `--pose=rest` sparkle handling. Adjudicated against the
#               oracle: the port's SHIPPED pose scores r +0.9994 against the
#               game where the reference scores +0.8727, and `--pose=rest` is
#               what this script compares.
#   ⚠️ title_jp is ALSO an era-sensitive bundle, so if this reference is ever
#   built from a different era than the exporter's pin, that row's cause changes
#   and this note stops applying. Check the md5s before trusting it again.
#
# So the allowance is now a NAMED SET, not a count with an excuse. A DIFFERS on
# any other screen fails the run, which a count never could.
# 🔴 SIX MORE SCREENS JOINED THIS SET ON 2026-09-01 AND THE SET WAS NOT WIDENED.
# main_menu, extras, main_menu_jp, extras_jp, build_12, build_15. Measured, not
# diagnosed: the difference is full-frame, it is EXACTLY ZERO on unblended
