Sylpheed port agent 0e41f5381d port: take formats-pin-2026-08-30b and stop owning the +0x08 read
The tag was cut within the iteration, so screen.rs now calls
ui_layout::loop_length_units and its local RATC guard and byte read are deleted.
One line, as predicted -- and the doc comment promising that deletion is the only
reason a temporary reading did not quietly become permanent.

A pin bump moves the whole crate, not one function, and this pin is recorded
load-bearing, so both commits between the tags were read before taking it:
b5df02a adds the public function, d020845 is comment-only -- two 'fixed code
under an unfixed description' corrections. No behavioural change in either, and
the oracle RMSEs confirm it: main_menu 13.21, extras 13.38, title 14.16, all
identical across the bump.

d020845 is worth noting for what it is. The rest override's comment still claimed
it tested the shifted time reading that the record-layout fix had refuted, and a
continue branch was documented with the pre-fix rule. Both are the same failure
this port hit in spin_period_units: a doc comment describing the rule the body no
longer implements. Three instances now, across two agents and two languages.

examples/record_loop_control.rs deliberately did NOT follow the API. The moment a
control calls the thing it exists to check it stops being a control and becomes
the API tested against itself; the falsifier means something only because the
reading is independent. Re-run at the new pin, unchanged. So the port holds one
copy of this reading instead of two, and it is the copy whose job is to disagree.

# The decoders, PINNED BY REVISION. Not vendored and not reimplemented: they are
# disc-wide verified in their own repository, and floating the pin would let a
# decoder change land mid-milestone -- exactly the confusion this prevents.
#
# `sylpheed_formats::media` in particular owns the cases where one playable thing
# is not one archive entry (segment-spanning reads, multi-sub-wave banks, and the
# continuous cutscene-voice stream). Do not re-derive those here.
#
# Pin moved f817dd5 -> 7eeae30 on 2026-08-29. WHAT I WANTED FROM IT: `UiBuild`
# gained a public `records` map (record name -> the nested `.rat` leaf's byte
# range). Without it a consumer could not locate a leaf at all: `parse_build`
# sorted T8aD children into `sprites` and `.rat` children into a PRIVATE map, so
# the focus ring -- which lives inside `ptbtn0Nf.rat`, a record the parent
# bundle declares no element for -- was unreachable through the public API.
# Also brings `Keyframe::rotation_deg`, which the game does render.
#
# PINNED BY TAG, not by sha, and MISSION §2 now requires it. The reachability
# risk this comment used to warn about is closed: a sha reachable only from an
# `auto/*` branch is orphaned when that branch is deleted or -- worse --
# SQUASH-MERGED, because squash creates new commits, so `main` would look like
# it contained the work while this pin became unreachable. A tag is a permanent
# ref, it says what it is here in the file, and it fails loudly at FETCH rather
# than silently at build. `formats-pin-2026-08-29` is 7eeae30.
#
# Previous pin note, kept because the reasoning still holds:
# Pin moved 5414db3 -> f817dd5 on 2026-08-29. WHAT I WANTED FROM IT: `56cc7ac`,
# "a RATC child's name is stated, not inferred". A child was named by scanning
# backwards for the last printable run before its magic; for `pteff05.t32` the
# three trailing payload bytes are `38 41 58` = `8AX` and beat the real name, so
# the FULL-RESOLUTION BACKGROUND OF ALL FIVE MENU SCREENS registered under a
# name no element declares and resolved to no sprite. This port exported those
# screens without their background and said so in every render as "pteff05 (no
# sprite in the export)" -- which docs/DECISIONS.md then wrote up as correct.
# It was not. f817dd5 is the last commit touching `crates/` on that branch.
#
# Previous pin note, kept because the reasoning still holds:
# Pin moved 8b6dbcf -> 5414db3 on 2026-08-28. WHAT I WANTED FROM IT: the fix to
# `ui_layout::rest()`. At 8b6dbcf a trailing run of identical keyframes was
# always treated as the exit, so an element with no exit animation rested at its
# invisible pre-roll -- `ptframe1`/`ptframe2`, the main menu's circuit bracket,
# which a capture of the running game plainly shows. 5414db3 is the revision at
# which that fix carries its disc-wide check (30 of 13 991 elements move, 4
# become visible, 0 become invisible), not merely the one where it was written.
# A PATH dependency now that the decoders and the exporter live in one
# repository. This deletes a whole class of failure that the two-repo split
# created: no pinned revision to go stale, no tag to keep alive, no commit that
# a squash-merge can orphan, and no way for the exporter to be built against a
# decoder it was never tested with. A decoder change and the exporter change it
# requires now land in the same commit or not at all.
# PINNED BY TAG, which is what MISSION section 2 prescribes and what the tagging
# rule exists for: "the RE agent tags when it lands something you need and tells
# you over the message channel -- that is how you stay current without floating."
# That is exactly what happened here.
#
# The tag carries the CORRECTED keyframe association: a placement group is an
# 8-byte header then `frames` x {u32 time; 36-byte pose}, so pose 0's time is the
# group's lead-in word and EVERY POSE IS TIMED, including the last. The working
# tree's copy still has the retired `SYLPHEED_KF_TIME_SHIFT` knob -- a superseded
# partial fix that got the association right but left pose 0 untimed, which is
# why testing it moved the untimed frame from last to first instead of removing
# it. The old reading is behind `SYLPHEED_KF_TIME_LEGACY=1` here.
#
# 🔴 THE COST, STATED: `sylpheed-cli` builds from the WORKSPACE crate, so until
# this lands on `main` the exporter and the reference renderer read DIFFERENT
# decoders and `tools/port/verify-screen` is comparing two eras rather than
# detecting drift. `tools/port/verify-capture` is unaffected -- it compares the
# port against oracle CAPTURES and never touches the CLI -- and it is the check
# that matters. Revert to the path dependency the day the tag is an ancestor of
# `main`.
# Bumped c -> d 2026-08-29. What I wanted from the new state: `d` carries parser
# and `audio.rs` changes on top of `c`. ⚠️ Its headline change -- Reborn's
# renderer drawing `rotation_deg`, and `compose` drawing a leaf that carries
# geometry -- does NOT reach this port from here: `sylpheed-cli` builds from the
# WORKSPACE crate, so the reference renderer stays unrotated until the tag lands
# on `main`. This bump is for the parser, not for the renderer.
