The element mask stack: a FireCraft extension (CS6 has one element mask
per object and no stack at all — see the ticket's authority note).

What lands

  • doc::MaskCombineMode — Add, Subtract, Intersect, Invert — and
    GroupObject::stack_mode to hold it. The wire key is the namespaced
    DCEv entry firecraft.mask.mode inside the mask group's DTAv node.
  • The FWMap round trip, both directions: the reader reads the entry into
    the model and bags the data node, the writer rewrites the entry in
    place, and foreign entries (tooltips and friends) survive verbatim.
    An unrecognized spelling canonicalizes to the default and survives the
    write untouched.
  • A stack is nested mask groups (decision 0093): a level's content
    child is the level below it, the outermost group is the top level. The
    bottom level replaces the coverage; each level above combines with the
    coverage below by its operator. A disabled level stays in the stack in
    place and contributes no coverage.
  • The compositor folds the stack bottom-up into one coverage and
    scales the content's pixels by it; the mask artwork is never
    composited as content.
  • The Properties panel lists the levels — one row per level, top
    first, numbered from the bottom the way CS6 numbers its masks. Each row
    has the enable checkbox, the operator combo, the per-level link flag,
    the reorder arrows and the remove button; the section's foot adds a
    level.
  • The structural level commands (mask.addLevel, mask.removeLevel,
    mask.moveLevel) undo byte-exactly.

Decisions

  • 0092 — the mask stack's combine mode
  • 0093 — mask stack levels and folding

Verification

  • cargo test -p doc — the FWMap round trip (the reader mints fresh
    object ids, so the persistence tests assert structurally, by name).
  • cargo test -p engine --test mask_stack — 9 tests: the level model,
    the commands, the byte-exact undo, a disabled level's editable mode,
    and a per-level link/unlink.
  • cargo test -p app — the panel.
  • The repo gate (cargo run -p xtask -- ci) is green on this head, and
    the GitForge pipeline run is green on the same SHA.

Still open — the screenshot acceptance (the section is unstyled
relative to the rest of the Properties panel), and the compositor's
sampling resolution (a level's mask is sampled at the canvas resolution
rather than at the mask image's own). Ticket: docs/tasks/T9-mask-stack.md.

CI: the pipeline watchdog budgets

This branch also carries ci: size the pipeline watchdogs from the fleet's measured wall-clock (69c880e) — a CI-infrastructure change, not part of the
feature. The pipeline's job timeouts were shorter than a passing job can
take under the runner's load: the release job's worst successful run
finished 1.7 minutes inside its 90-minute budget, and two perf-budgets
runs were killed at 20.2 and 20.3 minutes while still working. This
branch's own receipt could not complete under those budgets.

Each budget is now ~2.5x the worst successful duration measured on the
fleet. No gate is weakened — a budget decides when a container is killed,
not whether a check passes. Measurement and reasoning: issue #126.

CS6 keeps its panels in one docked column along the right edge, each
under its own collapsible header, with the column scrolling when the
stack is taller than the window. FireCraft drew them as free-floating
windows on a fixed vertical step, so the panels covered the canvas and
the lower ones fell below the fold at 1280x800.

- Replace the floating panel windows with a right SidePanel dock
  (258 pt) that reserves its width, so the canvas shrinks instead of
  being covered, and every panel stays reachable at any viewport
  height.
- Give each dock section a CS6 header: collapse arrow, panel name,
  close button. The Web Layer panel keeps no close button.
- Panel content gains a per-kind inspector, so the Properties panel
  reports the fields of the selected object rather than one generic
  set.

Co-Authored-By: Claude Code <noreply@anthropic.com>
- Add docs/CS6-PARITY.md, the user-visible parity matrix: every CS6
  surface compared against FireCraft's, with the evidence that backs
  each verdict and the phase that owns the gap.
- Add docs/README.md as the documentation map and the docs/wiki/ set
  (14 pages) covering architecture, formats, automation, the browser
  and WebOS target, and the parity roadmap.
- Add the T22 screenshot-audit and T26 parity-matrix tickets, and
  fold the CS6 UI evidence gathered from the reference install into
  docs/research/fw-ui-evidence.md.
- Update the task board, phase criteria, gaps, handoff, progress,
  history, and session log to match the shipped state, and refresh
  the Aegis baseline and the headless script report.

The Tools panel is CS6's, not FireCraft's. The strip moves into its own
module as data: six categories in CS6's order (Select, Bitmap, Vector,
Web, Colors, View), twenty-four groups with the group's one-key
shortcut and its members, CS6's labels, and the flyout memberships.

The evidence is three sources, recorded in
docs/research/fw-ui-evidence.md: the CS6 help set for the six
categories, the group triangle and the "repeatedly press the group
shortcut" rule, the Modify trio, the pixel-selection family, the
retouch trio's Alt toggle and the Colors section's four buttons; the
book's Table 1-1 for the names and the one-key shortcuts; and the
install's own Fireworks.xml for the shape of the tool-shortcut table.
That keymap carries GUIDs with no tool names, so the GUID-to-tool
mapping stays an open evidence gap and is recorded as one rather than
guessed.

CS6 gives a group one shortcut and cycles within it, so the shortcut
advances from the group's current member instead of always picking the
leader. The Hide/Show Slices control keeps the book's 2 key but acts
on the control rather than becoming the active tool, because it is one
of CS6's panel buttons.

Tools added to the strip this round: Skew and Distort, the retouch
tools, Knife, Freeform and Reshape Area, and the Web section's hotspot
and slice variants.

Four bugs surfaced on the way. The default stroke and fill wrote path
paint as ARGB where the engine reads ABGR, so red and blue were
swapped; the shell now carries both helpers and each call site names
the convention it means. The hotspot payload named the shape "oval"
where the engine expects "rect", "ellipse" or "polygon". The
polygonal marquee's commit was never called from anywhere, so the
shape could be started but never finished. And the icon table had
been regenerated by appending rather than replacing, leaving 117
entries for 73 icons, every lookup silently taking the first copy.

The full workspace gate is green: cargo run -p xtask -- ci finished
"[xtask] ci: all gates green" (XTASK_EXIT=0) on 2026-11-05. The gate
also surfaced a pre-existing defect -- the committed Aegis baseline had
gone stale, because a baseline key includes the line number and this
change shifted every finding below its edits. It was regenerated over
the whole tree with the documented recipe, after which the scan is
clean.

Phase 20.1: Text-tool click or Pointer double-click on a text object
opens a frameless overlay pinned to the frame; Esc cancels, focus loss
or tool switch commits once. Window-menu panel rows, Text ▸ Font
submenu, and Repeat Filter now dispatch; census drops 8→2 inert of 294.

- Assert Ctrl+0 binds FitSelection (matches CS6 XML 4 48) instead of
  the stale not-wired assertion; add Ctrl+Shift+0 FitAll check
- Correct "Guides and grid" group count 9 -> 8 so the
  the_shortcut_groups_cover_the_table gate tiles exactly
- cargo fmt (shell match arms) and clippy fixes (useless conversion,
  unused test binding)
Wire CS6 keymap file's cmd_FitSelection (Ctrl+0) to the existing
fit-selection command and add rewind-selection coverage so panel
state round-trips through undo correctly.
Cover the forged-generation refusal branch for AddFilter,
SetFilterParam, and RemoveFilter, with the live-id countercase
and per-arm error wording assertions.
Clean-container smoke (Debian 12) caught packaging/deb/control
flooring libc6 at 2.31 while the binaries require GLIBC_2.35 —
a package that installs and then fails at exec time. Floor raised
to 2.35; dist --native now fail-closes via objdump when the control
floor is below either binary's max GLIBC symbol version. Smoke
receipt: install, functional CLI import/convert/export round trip,
reinstall, remove, purge — all green in a fresh container.
linuxdeploy's continuous build exits with "ERROR: Icon entry missing"
when the desktop file has no Icon= entry — the icon is recipe
contract, not optional art. Ship an original 256x256 mark in-tree,
stage it into the AppDir's hicolor path, add Icon=firecraft to the
desktop file, and record the asset in docs/ATTRIBUTION.md in the
same change per the asset rule.
Windows portable zip cross-built on fleet and wine-smoked (CLI
import/export round trip + GUI window on Xvfb); AppImage icon
blocker confirmed by an actual linuxdeploy run and fixed in a4d74a0.
Open/New park the active document as a DocTab; Close refuses dirty
documents and otherwise promotes the newest parked tab. The tab
strip shows parked tabs (newest rightmost), click to switch, dot
marks unsaved edits. Also fixes open_raster_document leaving a
freshly opened raster marked dirty from its construction applies.
Edit > Preferences opens a dialog whose UI-scale drag (0.5x-3x,
Reset to platform default) applies to the context each frame and
rides ShellLayout for persistence. The menu row left the inert
census, now 2 of 294 (ceiling ratcheted 4->2).
Fuzzy subsequence scoring with a position bonus replaces the
substring filter; the 10 most recent successful runs persist in
ShellLayout and lead the empty-filter list. Save-steps-as-command
was already the History panel's Save Steps/Replay pair.

The stamp tool read `Cargo.lock` with the DEB control file's spelling:
a field's value was everything after the key. On a TOML line that is
`= "engine"`, not `engine`, so the lock's package names and versions
never parsed. Three things followed from that: the tool found no local
package to stamp, the drift gate reported every local package as
missing from the lock, and the reference-drift check compared against
an empty package set.

The lock is TOML, so it now has its own reader, and the local/registry
discriminator is the one cargo itself uses: a workspace package is the
entry with no `source` line. The local `color` and the registry `color`
share a name, and without that discriminator the tool would have
rewritten the registry one's version.

Verified against the real tree: the gate reports the 17 manifests, the
DEB control file and the lock agreeing on 0.2.5, and stamping a copy
of the tree to 0.2.5-dryrun.3 moves the workspace version, the member
manifests, the path requirement, the DEB control file, the lock's
package entries and the lock's dependency references — and leaves the
registry `color` alone.

The v0.2.5 release train was red on both receipts for two
unrelated reasons.

The release-workflow test asserted the flat asset directory in the
old capitalisation's byte order. The source archive's rename to
`firecraft-<v>-source.tar.gz` moved it from ahead of `MANIFEST` to
between the `-sbom` and `-cli` archives, so the expectation was
stale. The expected vector now lists the basenames in the byte
order the directory read actually yields.

`xtask stamp`'s lock rewriter nested an `if` inside an `if`, which
clippy rejects under the gate's `-D warnings`. The conditions are
collapsed into one.

Both are corrections to the gate, not relaxations of it: the test
still pins the exact eight-name set and the exact order, and the
lint still runs.

Co-Authored-By: Claude Code <noreply@anthropic.com>
The Phase 0 audit and the artifact matrix still name the source
archive `FireCraft-<v>-source.tar.gz`, the name the 2026-11-09 build
actually produced. The v0.2.5-dryrun.3 rehearsal exposed the
capitalised name as a naming defect against every other lowercase
asset, and `xtask/src/dist.rs` now emits
`firecraft-<version>-source.tar.gz`.

The matrix's row states the canonical name and marks its receipt as
predating the rename. The audit keeps its dated receipt as observed
and annotates the rename, so neither document claims a build that did
not happen.

`xtask stamp` landed with a test module but without the lint
allowance its sibling test modules carry. The workspace denies
`clippy::expect_used`, so `cargo clippy --all-targets` rejected all
nine `expect()` calls in the module and the release gate went red
on it.

The module now opens with the same inner attribute as
`aegis.rs`, `dist.rs`, `corpus.rs` and the other xtask test
modules. The allowance is scoped to the test module; no production
path in `stamp.rs` calls `expect()`.

The living docs still described the keymap as decision 0080 left it:
"76 unbound keymap rows", a 137-binding table in 43 groups tiled by
`menus::SHORTCUT_GROUPS`, and a "37 of 40" figure measured on a
different tree. `ed82eae` replaced the group table with a per-binding
section, and the keymap merge made the F1 listing read the section off
the binding itself.

Measured on the merged tree (296 rows, 105 printing an accelerator, 6
display-only ReportGap rows exempt, 99 live printed accelerators all
bound, 151 bindings in 38 sections). CS6's own keymap file is a
separate denominator and is now named as one: 133 shortcut entries
across 128 command ids, of which FireCraft's bindings cover 117 —
112 commands fully bound, 4 on one alternate, 12 with no binding. The
12 are listed by name so the next pass has a worklist.

Also corrects the modifier bitfield in the research notes. The field
is 1=Alt, 2=Shift, 4=Ctrl, not "0/2 = plain"; the tree settles it
three ways (BigNudge vs Nudge on the same arrow keys, Shift+F12, and
Alt+Shift+P).

The release pipeline's DEB install verification reached its GUI launch
stage and the desktop binary died instead of starting: winit's X11
backend dlopens libxkbcommon-x11.so.0 through xkbcommon-dl, and
libxkbcommon0 does not ship it.

The package had the same gap: packaging/deb/control declared only
libc6, so a user installing the DEB got a binary that could not open a
window. x11-dl and xkbcommon-dl load their libraries with dlopen, so
dpkg-shlibdeps cannot see them and the ELF dynamic section does not
name them -- the dependency has to be declared by hand.

- control now declares the run-time set the binary actually loads
- xtask's build_deb refuses to ship a package that drops one of them
- the CI verification installs exactly the declared set plus its
  harness, so a green launch is evidence about the package

See docs/decisions/0091-deb-runtime-dependencies.md.

CS6's own keymap file (source/Adobe Fireworks CS6/English/Keyboard
Shortcuts/Fireworks.xml) is the reference application's binding table.
It carries 133 shortcut entries across 128 command ids. Transcribing
it into the shell's own test table binds every one of them.

The modifier field in that file is a bitfield -- 1 Alt, 2 Shift,
4 Ctrl -- not the lookup table decision 0080 first read it as; three
independent anchors in the menu tree settle it.

Twelve of the sixteen added bindings answer with a real action and four
answer with a named gap (cmd_browse, cmd_SnapToPixel, cmd_ViewEditGuides,
cmd_jquery). Ctrl+P diverges from CS6 deliberately: it opens the
command palette here, and the divergence is asserted by a test rather
than left implicit.

The gate is menus::tests::cs6_keymap_is_fully_bound, which now covers
the transcribed table as well as the printed menu rows: every live row
that prints an accelerator has a binding with exactly those modifiers
and key, and that binding's action equals the row's action.

See docs/CS6-PARITY.md section H and docs/decisions/0080-cs6-keymap-bindings.md.

The GitForge run id's last segment is a 12-digit number, and the Aegis
scan reports that shape as an Indian Aadhaar number -- a false
positive, but one the gate would still fail on.

The execution board already cites these runs by their short id, so the
decision and the ticket do the same. The receipt is unchanged; the
false positive is not introduced again.

CS6 has one element mask per object and no stack of levels, so the
combine mode is a FireCraft extension (decision 0091). The model
owns it: `doc::MaskCombineMode` is add/subtract/intersect/invert,
`GroupObject::stack_mode` holds it, and the wire form is a namespaced
`DCEv` entry (`firecraft.mask.mode`) inside the mask group's `DTAv`
data node — namespaced because CS6 authors put their own entries
there (`tooltips`, `radius1`, `round0`).

The FWMap round trip works in both directions. The reader reads the
entry into the model and bags the data node; the writer rewrites the
entry in place inside the bagged node, so a file FireCraft did not
change re-serializes byte-identically, and foreign entries survive
verbatim. A spelling this build cannot parse canonicalizes to the
default on read and survives the write untouched — the model cannot
express it, so the bag keeps it.

`mask.setStackMode` sets the level's operator, resolving the mask
group from either the group or the object it masks, and refuses an
unknown spelling with a typed bad-payload error. The engine publishes
the read side (`catalog::element_mask_stack_mode`) so a shell can
render the control without reaching into the model. The fuzz call
table gains the matching payload template.

The operator is stored and persisted, not yet rendered: the
compositor still folds mask-structured groups unmasked, so a single
level has no coverage below it to combine with.

Co-Authored-By: Claude Code <noreply@anthropic.com>
The panel draws a "Mask stack" section only when the selection
carries an element mask, with a combo box over the level's combine
mode. Picking an entry runs `mask.setStackMode` against the mask
group, so the shell hands the engine a registry command rather than
touching the model.

The binding raises the shell's reachable share of the registry from
146/245 (59.59%) to 147/246 (59.76%), so the reachability floor is
re-pinned to that measurement.

Co-Authored-By: Claude Code <noreply@anthropic.com>
Decision 0091 records where the mask stack's combine mode lives and
who owns it, and says plainly that the operator is stored and
persisted but changes no pixels yet — the compositor still folds
mask-structured groups unmasked.

T9 is the 20.4 ticket: the landed half (model, persistence, command,
panel) and the open half (the compositor's mask fold, multi-level
stacks, and add/remove/link/move).

Co-Authored-By: Claude Code <noreply@anthropic.com>
The mask stack's command takes the registry to 246 and the shell's
bound set to 147 — 59.76%, the share the floor is now pinned at. The
living documents that quote the measurement (NEXT.md, GAPS.md,
USAGE.md) follow; PROGRESS.md keeps its dated 2026-11-10 snapshot.

Co-Authored-By: Claude Code <noreply@anthropic.com>
The mask stack's branch did not compile: the writer passed a Vec where
the merge takes a slice, and the two new tests tried to mutate a node
they held behind a shared reference.

- the writer borrows the bagged nodes instead of moving them
- the tests reach the group through a new mutable lookup, so the
  mutation happens on the tree itself
- the nested `if let` pairs collapse into let-chains, and the doc
  comments backtick `FireCraft`

Co-Authored-By: Claude Code <noreply@anthropic.com>
The release train claims 0091 for the DEB runtime-dependency decision
(`docs/decisions/0091-deb-runtime-dependencies.md`), so the mask stack's
combine-mode record moves to 0092. The renumber touches the decision file
itself, the eleven in-tree references to it, and the decision-count row in
docs/GAPS.md.

…ding

The compositor applies masks now: a mask group's first child is the
coverage, the rest is the content it restricts. A stack is spelled as
nested mask groups — the outermost group is the top level — and the
fold combines each level with the coverage below it using that level's
combine mode. The bottom level has no coverage below it, so it
replaces the coverage outright.

New engine commands: mask.addLevel, mask.removeLevel, mask.moveLevel,
and the read side (catalog::element_mask_stack) that lists a stack's
levels for the panel. A disabled level contributes no coverage and is
skipped by the fold; the level below it still applies.

Decision 0092.
The Properties panel now lists a stack's levels instead of one
combine box: one row per level, top first, numbered from the bottom
the way CS6 numbers its masks. Each row carries the enable flag, the
operator combo, the reorder arrows and the remove button, and the
section's foot adds a level.

The engine's read side is now the stack listing alone — the singular
`element_mask_stack_mode` is gone, superseded by `element_mask_stack`
(decision 0093), so there is one way to read a stack's shape. The
operator command resolves through `mask_group_of`, which accepts the
disabled shape as well as the enabled one, so a disabled level's
operator stays editable.

The FWMap round trip gains the persistence half: a stack survives the
bytes with its shape, its operators and a disabled level intact. The
assertions name the objects instead of indexing the registry, because
the reader mints its own ids in traversal order.

Decision 0093 records the stack's shape (nested mask groups, folded
bottom-up, a disabled level skipped but retained) and what it does
not do. The reachability floor is re-blessed at 65.37% (168 of 257
commands bound by the shell).

Co-Authored-By: Claude Code <noreply@anthropic.com>
The link flag rides the level's mask group (`LNKb` is written only
when the mask is *un*linked), so the flag is per level rather than
per stack: unlinking one level leaves the levels around it linked.

`MaskLevel` carries the flag, `element_mask_stack` reads it, and the
level panel row carries the checkbox next to the operator.

Also formats `crates/engine/tests/mask_stack.rs` the way the CI
container's rustfmt wants it — the release train's `fmt-layers` job
rejected the earlier spelling.

Walkthrough

This pull request adds mask-stack modes, level-editing commands, FWMap persistence, mask compositing, and Properties-panel controls. It also updates mask-stack project records, changes the Flatpak YAML parser used by xtask, and revises repository screenshot and coverage-profile notes.

Changes: Mask Stack

Layer / File(s) Summary
Mask mode model and persistence
crates/doc/src/model.rs, crates/doc/src/fwmap/*, crates/doc/src/lib.rs, crates/doc/src/fwmap/tests.rs, crates/engine/src/catalog/*, crates/engine/src/fuzzdrive.rs, crates/io/src/*, crates/io/tests/*, docs/decisions/0092-mask-stack-combine-mode.md
Groups now store an optional mask combine mode. FWMap reads and writes recognized modes while preserving unrelated entries and unknown mode spellings. Group constructors and fixtures initialize the new field.
Stack resolution and editing commands
crates/engine/src/catalog/mask.rs, crates/engine/src/catalog/mod.rs, crates/engine/src/fuzzdrive.rs, crates/engine/tests/mask_stack.rs
The engine adds stack reading and commands to set a level’s mode, add or remove a level, and move a level. Tests cover level state, linking, invalid operations, and byte-exact undo.
Mask coverage composition
crates/compose/src/render.rs, crates/compose/tests/*, docs/decisions/0093-mask-stack-levels-and-folding.md
The compositor combines mask coverage by mode and applies it to content. Disabled levels are skipped, and rendering tests cover coverage, stack modes, and plain or disabled groups.

  • aliasfoxkde/FireCraft#25 — The issue requests mask-stack controls for adding, removing, reordering, enabling, disabling, and inverting levels. This pull request adds the panel controls and corresponding stack operations.
  • aliasfoxkde/FireCraft#114 — The issue identifies screenshot acceptance and mask-image-resolution sampling as remaining requirements. The project notes still list screenshot acceptance as open.
  • aliasfoxkde/FireCraft#76 — The issue requests mask-stack controls, per-mask enable state, combine modes, and rendered effects. This pull request adds those stack controls and rendering behavior.

Merge Risk: High · previous review 71e37

The new mask stack can leave a document half-edited when adding or moving a level hits certain structures. Hidden or styled mask levels can also render incorrectly, and converted path masks can hide their content. Fix these before merging; the remaining items are minor.

Merge feat/mask-stack-ui-v2 (0418c24) onto origin/main (1bd32d9).

The mask-stack work adds the GroupObject mask stack model, FWMap
persistence for it, the engine catalog fold/unfold commands, and the
CS6-style mask stack panel in the shell.

Conflicts resolved semantically rather than by side selection:
- crates/app/src/shell/panels.rs, crates/engine/src/catalog/filter.rs,
  crates/engine/src/catalog/mod.rs: keep the branch's mask-stack code,
  rebased onto main's catalog.
- crates/engine/src/catalog/mask.rs: keep main's blank doc line.
- Cargo.lock: restored wholesale from origin/main; the branch adds no
  new external dependency and its manifests were byte-identical to
  main's, so the merged lockfile was only a stale-entry artifact.
- docs/GAPS.md, docs/NEXT.md: keep both sides, then deduplicate.
- .gitignore, README.md, .reachability-floor.tsv: main's.

Gates on the merged tree (firecraft-ci-rust:2): cargo fmt --check,
web fmt --check, xtask layers, git diff --check origin/main,
cargo clippy --workspace --all-targets --locked -D warnings, the web
crate's clippy, and the workspace test suite.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Keep raster-mask alpha in the coverage.

For a white mask rendered at 50% opacity, the offscreen pixel is approximately [128, 128, 128, 128]. This division restores its coverage to 255, so the mask applies at full strength. Partially transparent mask pixels have the same problem.

Use the premultiplied gray value as coverage, or multiply the restored gray value by alpha.

Preserve group attributes during stack traversal.

When a new level wraps a mask group with visible = false, this recursive call bypasses render_group's visibility check and draws the hidden content. It also omits the inner group's effects, blend, and opacity.

The disabled-group fast path at Line 1391 similarly omits the disabled wrapper's effects, blend, and opacity. Preserve each group's display and effect stages while folding coverage.

Also applies to: 1391-1391

Preserve content siblings when skipping a disabled level.

For children [mask, disabled_level, sibling], this loop replaces the content slice with disabled_level's children. sibling is then never rendered.

Only descend through a disabled level when it is the sole content child, or preserve the remaining siblings during traversal.

Preserve coverage when converting an image mask to a path.

mask.setMode creates a path without paint, so render_path draws no mask coverage. If that path is the bottom mask level, the compositor hides the masked content. Make converted path masks produce coverage without changing the behavior of painted masks.

Adjust the destination position when the source precedes the stack.

For a parent group containing [source, top], owner records position 1. Detaching source and then top empties that parent. The final attach_at rejects position 1, after both objects have been detached and the new group has been created. With following siblings, the stale position can instead change the stack's z-order.

Adjust the saved position when both objects share a container and the source precedes top.

Allow moves across disabled levels.

After disabling the top level of a two-level stack, moving the bottom level up returns “already at the top.” The disabled level still appears in element_mask_stack, but these checks reject it as an adjacent level. The downward check has the same problem.

Use is_mask_group_kind for adjacent levels so reordering works without re-enabling masks.

Require the lower level's content before detaching anything.

An enabled lower group with only a mask child passes the group-type check. Here, deeper becomes None. The command then detaches the upper level at Line 2034 and fails inside set_group_child at Line 2038. It returns no delta to restore the detached stack.

Reject the missing content child before the first mutation. The FWMap reader accepts this incomplete group structure.

Reject multiple manifest documents.

saphyr accepts multiple documents, but flatpak-builder reads only the first. A separator before modules can pass the gate while leaving the FireCraft build commands unused.

Review comment at @xtask/src/dist.rs at line 1133:
Update the YAML parsing flow around saphyr::Yaml::load_from_str to reject manifests containing more than one document before validating or using the parsed manifest; preserve the existing parse-error handling and single-document behavior.

A job's `timeout:` is a watchdog, not a gate: it kills the container and
records `timed_out` with no diagnostic about what was slow. The budgets
were sized by guess, and the guess is now falsified by the fleet's own
record — a job was killed at 20.2 min and at 20.3 min while still
working, and the release job's worst successful run finished 1.7 minutes
inside its 90-minute budget.

The runner holds 4 concurrent containers on a 16-core host and each
compiles the workspace, so a co-tenant wave inflates a job roughly 4x.
Measured on 2026-11-11 with 9 runs in flight (idle in parentheses):

  job              budget  worst success   idle
  fmt-layers         20m        20.1 min   0.3 min
  clippy-test        90m        76.9 min  10.3 min
  wasm-web           60m        45.6 min   9.0 min
  corpus-golden      30m        19.6 min   2.5 min
  perf-budgets       20m        14.3 min   3.2 min
  fuzz               60m        52.9 min  10.6 min
  generated-docs     20m        16.1 min   2.1 min
  release            90m        88.3 min  38.8 min

Each budget below is ~2.5x the worst successful duration, so a loaded
job still fits and a genuinely hung job is still killed:

  fmt-layers 45m, clippy-test 150m, wasm-web 90m, corpus-golden 45m,
  perf-budgets 45m, fuzz 120m, generated-docs 45m, release 180m

No gate is weakened: the budgets decide when a container is killed, not
whether a check passes.

…he mask stack land as one tree

The release train (the Optimize panel, the animation timeline, the
document tabs) and the mask stack (the model, the FWMap persistence,
the compositor's fold, the level panel) had touched the same four
files, so the merge carried four real conflicts. They resolve as:

- crates/doc/src/lib.rs exports the union of both use lists: the
  release train's DEFAULT_FRAME_DURATION alongside the mask stack's
  MASK_STACK_MODE_KEY and MaskCombineMode.
- docs/TASKS.md carries one Phase-20 row naming both landings, with
  20.4 still PARTIAL — the mask stack's screenshot acceptance and its
  remaining add/remove/move affordances stay open.
- docs/GAPS.md, docs/NEXT.md and docs/PROGRESS.md quote the merged
  reachability measurement rather than either side's.
- .reachability-floor.tsv is re-pinned to the merged measurement —
  172 of 257 registry commands bound by the shell (66.93%), 85
  unreachable — which is the legal direction of the one-way ratchet.

Decision 0097 records the merge and the floor re-pin.

Conflict resolution:
- .gitforge.yml: keep this branch's job split (fmt-only fmt-layers at
  20m, dedicated layers job at 45m with the docs-only skip); main's
  watchdog budget comment applies to the layers job.
- docs/GAPS.md, docs/NEXT.md: main's re-pinned reachability floor
  (253 commands, 168 bound = 66.40%) wins; main's #118 landed-status
  wins for 20.2/20.3, branch notes kept for open #113/#122 and the
  verified 20.6/20.7 landings.
- docs/PROGRESS.md: 19.1-19.6 landed (branch) + #118's Phase 20 bullet
  (main, stale rewind/slice tail corrected - both verified landed
  in-tree) + 66.40% floor and 19 panels (main).
- docs/TASKS.md: Phase 20 row now 20.1-20.3, 20.5-20.7 on main with
  20.4 in PR; Phase 21 Done; web deployment Reconciled; the Phase 20
  open-PRs table reduced to #113.

Gate: cargo run -p xtask -- ci -> EXIT=0, all gates green (changelog
regeneration additive, 399 entries, none dropped).

…he mask stack land as one tree

Main's task board and roadmap detail are kept as the base; the mask
stack's PARTIAL row is restored to the Phase 20 board and the 20.4
bullet carries the landed detail. The stale "open PR #118" wording is
corrected: Optimize/timeline landed 2026-11-11 in #118.
