# 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.
