refactor(ui): D4c map context — clock, scale bar and contours leave the Display screen - #1586
Conversation
The clock pill, the scale bar and the contour layer are switches for what the Map draws, and they lived two levels inside the central Settings tree, on a page the rider could only reach by leaving the map. They are rows of the map's own contextual sheet now, which is the only home they have. The Map declares its own five-row table (#1515 D4c): the ride's four actions, unchanged and pinned equal to `RIDE` by test, plus one door that swaps the sheet for a three-switch display sheet. Statistics, Climb and Ride control keep `RIDE` byte for byte. `MAX_SHEET_H` 240 -> 244 and `MAX_ROWS` 4 -> 5 follow from the fifth row; no other drawer geometry moves. Two row shapes arrive with it. A switch row (`ContextAction::Toggle`) flips a `bool` in place, draws the settings tree's own slider instead of a chevron and keeps the sheet up, so the rider sets all three in one visit and the frozen map behind is drawn again once, on the close. The Map display row replaces the sheet with a sheet that is already landed (`ContextDrawerScreen::swapped_in`), which costs exactly one draw of the screen below — the band the taller sheet gave back — instead of the four a sliding sub-page over a map would have cost. The render key gains no field: all three settings are device-only, so under an open sheet only the rider can move one and only the selected row's, and `DrawerKey::committed` already carries that. `Settings` is untouched: VERSION stays 18, the three fields keep their pinned offsets. `settings/display.rs` keeps only the idle-return picker, which governs the whole UI rather than map chrome. `toggle_slider` moves into the shared row vocabulary, since it now has two homes. Six `[display]` catalog keys leave all four languages and four `[map_context]` keys arrive. Closes #1585 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The Drawers section said the four riding views share one table. The Map adds a fifth row now, Map display, which replaces the sheet with a shorter sheet of three switches. The switch is the fourth row shape: it shows its own state, flips it in place and keeps the sheet open, and what it changes is not visible until the sheet closes, because the screen below a sheet is held still.

…page One sweep on the final head: 305 -> 311 frames. The four `ride-context*` frames are renamed `map-context*` (the recipes are unchanged; only the Map they were always shot over now declares its own table), `ride-context.png` is re-shot over Statistics so the unchanged four-row RIDE table stays covered, and six new frames carry the map display sheet — its three switches, one of them flipped, and the labels in the other three columns. `display.png` and `display-idle-return.png` follow the one-row Display page, and the second one is a recipe corrected while it was being re-shot: `B u p d p d d p` pressed *Contours*, not the picker the filename claims. Every other frame is byte-identical: nothing else moved. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Adversarial review of 140ea262, read against issue #1585 and the code around it, with read-only probes in the implementer's worktree. No blocking findings. Six items below, all Minor or Nit.
Blocking
None.
Minor
1. Nothing drives the sheet↔sheet swap through the parity oracle — the one harness that can see the failure the sweep provably cannot.
apps/obc-sim/tests/dirty_parity.rs:715-724 squeezes the map sheet open and presses row 0; nothing in the replay reaches row 4. The PR itself establishes that the --png sweep cannot show a frozen base (the headless host never claims a resident frame, apps/obc-sim/src/main.rs:1368, and ui_runtime.rs:291-296 gates sheet_only() on exactly that), which leaves dirty_parity as the only place a resident host is checked to actually repaint the band the taller sheet gave back. What is pinned today is the mechanism: the_display_row_swaps_the_sheet_and_back_lands_on_the_map asserts needs_base() is true on the first tick and false on the next, and the neighbouring the_open_pays_no_base_render_and_a_page_slide_pays_for_what_it_uncovers pins the page-slide twin. That is enough for me to accept the slice, but the concrete gap is real: if a later change drops needs_base() from sheet_only()'s conjunction, 88 px of the five-row sheet's ink stays on the panel until the sheet closes, and every test in this PR still passes. A two-step addition to replay() (squeeze on the Map, Step(-1), Select) would close it. Follow-up, not this round.
2. The one-shot is spent by the tick, not by the draw.
firmware/obc-app/src/screen/context_drawer.rs:686-690 takes uncovered inside tick_timers. The pass order makes that correct on every host I traced — gestures land at stage_input and the tick at stage_ui of the same run_pass (device_core/pass.rs:348-362), and handle_input applies gestures before advance_animations (app.rs:2767-2770) — so the frame that consumes the flag is the frame that draws. The failure mode is a frame that is consumed and then not presented: the board latches pending_map_redraw = true on a transport fault (firmware/obc-fw-nrf54l/src/ride.rs:2887-2890), and the retry pass ticks with uncovered already false, so the re-render is sheet-only and the uncovered band keeps the old ink until the sheet closes. Rare, and the existing settled one-shot has exactly the same shape (settle() also retires itself in handle, :598), so this is a consistency note rather than a regression this PR introduces. Worth one line of doc, or clearing the flag on draw rather than on tick.
3. toggle_slider moved into screen/vocab/rows.rs but was not added to check_screen_vocabulary.py's LANDMARKS.
I ran the guard: it passes (14 landmark definitions), and rows.rs already carries ledger_row and draw_guarded_rows, so the "one landmark per vocabulary module" rule the script states is still satisfied and nothing that was enforced before is enforced less now. But the issue's own sentence names this guard as the thing that keeps a two-home helper honest, and the helper now genuinely has two homes (settings/power.rs:96, settings/bluetooth.rs:107, context_drawer.rs:853). As it stands, a fourth screen re-declaring its own 50 × 28 slider next to its draw code would build and pass every check. Acceptable scope call for this slice; the one-line addition is worth a follow-up.
4. The German, French and Spanish door labels drop the "map" qualifier, and the comment that justifies it says something the code does not do.
i18n/de.toml explains Anzeige with "the sheet it opens says which display it is about". It does not: draw_root (context_drawer.rs:837-864) draws the row table and nothing else — only draw_editor writes a title, and MAP_DISPLAY has no editor row. So a German rider presses Anzeige and gets Uhr / Maßstab / Konturen with nothing naming the map, and Anzeige / Pantalla are also the settings screen's own titles (display.title = "ANZEIGE" / "PANTALLA"). English "Map display" is self-contained; the other three are not. Kartenanzeige genuinely does not fit — the deleted de comment's own datum is 11 Body glyphs = 154 px, so 13 glyphs is ~182 px against a 164 px door budget — so the fix is a shorter map-qualified reading, or a comment that states the real reason (it does not fit) instead of one that is false. Copy, not correctness.
5. One line of the new render-key test restates its setup.
In a_flip_under_the_sheet_moves_only_the_drawer_key: assert_eq!(RenderKey { drawer: quiet.drawer, ..flipped.clone() }, quiet, "the drawer's slot is the only one") cannot fail while a drawer is on the stack. App::render_key returns early once drawer_key() answers (render_key.rs:294-302), so every other slot is None in both keys and shape is untouched by a flip — the assertion is true by construction. The rest of that test is load-bearing and does fail under the mutants it names (quiet.map.is_none(), camera + fix moving nothing, assert_ne!(flipped, quiet), committed == Some(0), and the single invalidation on close), so the test is sound. Flagging it only because the same line exists in the D4b twin and this repo has three incidents of exactly this shape.
Nit
6. The harness copy of the rows-0-3 pin compares labels only.
harness/screens.rs:223-227 zips MAP.rows against RIDE.rows and compares rendered English strings; the action comparison lives only in context_drawer.rs's the_map_table_is_the_ride_table_plus_one_door. Both are in this PR, so the property is covered — I checked that a row-order swap fails the zip (labels differ per position) and an action swap fails assert_eq!(m.action, r.action). Just noting the harness copy alone would not catch an action swap. Same shape: the "no screen declares MAP_DISPLAY" loop enumerates six screens rather than the whole Screen census, so a seventh screen declaring it would slip past.
Deviation dispositions
(a) map-display-clock-off.png and the rewritten recipe comment — ACCEPTED, verified true.
ui_runtime::sheet_only() requires self.resident_frame (ui_runtime.rs:291-296), and apps/obc-sim/src/main.rs:1368 deliberately does not call set_resident_frame on the headless path ("composes one frame into a buffer that holds nothing, so every screen has to be drawn, including a base a resident host would leave standing under a sheet"). The frame genuinely cannot show the frozen base, and the honest comment is the right call. The claim the picture cannot make is carried at test level by a_flip_under_the_sheet_moves_only_the_drawer_key (key.map is None, camera and fix move nothing, the close is exactly one invalidation), by the structural early-return in render_key.rs:294-302, and by dirty_parity's resident-vs-reference oracle — with the coverage gap named in Minor 1.
(b) #[allow(clippy::enum_variant_names)] on ContextToggle — ACCEPTED. Each variant is named for the Settings field it binds to; read and flip read as two aligned three-arm matches because of it. The allow carries its reason inline. Right trade.
(c) Rows 0-3 pinned by rendered labels + actions — ACCEPTED, with Nit 6. ContextAction derives PartialEq, so assert_eq!(m.action, r.action) is a real comparison, and the zip pins order. Since available() is a pure function of the action, identical actions also give identical availability predicates — the issue's "same predicates" requirement follows rather than needing its own assertion.
(d) toggle_slider not added to LANDMARKS — ACCEPTED for this slice, see Minor 3. It is a scope call I agree with; the follow-up is one line.
(e) The sweep predates the rebase — ACCEPTED, verified. git diff --name-only 8ae896d6 948d5e7c over the 15 rebase commits touches only README.md, AGENTS.md, CLAUDE.md, docs/**, tools/docs_copy.py, tools/justfile, tools/obc.bash, tools/tests/test_docs_copy.py. No path under firmware/, apps/ or host/, and no fixture. Nothing in that set can move a pixel the simulator draws, so the sweep taken on the pre-rebase head is valid for 140ea262.
What I probed and cleared
The five-row Map table. screen/mod.rs:1302-1308 splits Map off and leaves Statistics | Climb | RideControl on &RIDE. Rows 0-3 of MAP are RIDE's by label and action, in order; the ride actions' predicates therefore cannot drift. Scripts that walk rows 0-3 are untouched: DETOUR_PRE C d p w still lands on Detour, routeswap*'s C d d d p d p still lands on Routes, p p p p C p C still opens the Up-ahead sheet from row 0, and present.rs:1089-1091's chord → Step(2) → PoiMenu still lands on POIs. dirty_parity's replay presses row 0 and is unaffected; I ran the binary — 9 passed. grep for C u found the three new recipes and nothing pre-existing, so the wrap that now reaches row 4 does not disturb an old frame.
The sheet swap. swapped_in stamps opened_ms = now_ms.wrapping_sub(OPEN_MS); visible_height uses wrapping_sub, so this is correct even at now_ms < OPEN_MS. On the first tick opening == 0 and sliding == 0, so next_wake_ms is None and the sheet is at full height — the test asserts both, and either half fails if the open replays. The one-shot is consumed (core::mem::take) into needs_base, and the test's second tick_timers proves it: if the || uncovered term were dropped, the first tick would overwrite the constructor's true with false and the assertion fails; if the flag were never set, the same assertion fails. Not a tautology. moved is true on the first tick because shown_h starts at -1, so the swap is always reported dirty independently of the key. toggle_drawer (app.rs:2326-2337) compares Screen::row(), both sheets are ContextDrawer, so Down+Back over the display sheet pops it and does not re-push — pinned by the render-key test's close. Back returns Transition::Pop onto the Map, not the parent sheet — pinned directly.
The toggles. ContextAction::Toggle(t) => { t.flip(cx); return Some(Transition::None) }; each arm writes exactly its own field (context_drawer.rs:264-269) and the harness test checks the other two are untouched per row. available() is unconditionally true for MapDisplay | Toggle(_), and key().4 == 0b111 is asserted, so the mask handling is right and toggle rows can never draw recessed. Persistence rides App's one before/after == (app.rs:3013) and settings_dirty is asserted after each of the three flips in the app-level test — the old test asserted the opposite (!settings_dirty inside Settings), so this is a real change of claim, not a ported assertion. The render key: committed now reports the selected row's bit for a Toggle and is byte-identical to the old self.value().map_or(0, …) for every Edit row (value() reads the same selected row). The "no new field" argument holds — I confirmed map_clock / map_scale_bar / map_contours carry no ble_writable marker in settings_table! (settings.rs:555-622), so under an open sheet only the rider can move one, and only the selected one.
The Display screen. Three rows out, ROWS 4 → 1, IDLE_RETURN = 0, Press reduced to the picker toggle; the picker recipe corrected to B u p d p p, which idle_return_picker confirms opens the editor from row 0. screen/mod.rs's Screen enum is untouched and its size_of == 104 assertion passes. settings/mod.rs loses only toggle_slider — no list, index or N_ITEMS change. No orphan keys: DisplayClock, DisplayScaleBar, DisplayContours and their *Sub twins have zero references anywhere in firmware/, apps/, tools/, docs/ or ui-snapshots.sh, and each catalog's [display] is now exactly title + idle + idle_sub. Six out, four in, in all four languages.
One home. map_clock / map_scale_bar / map_contours are written in context_drawer.rs and nowhere else; the surviving reads are map.rs:242,309,363 and screen/mod.rs:1405, all readouts. check_one_home.py reports 7 drawer-written settings (floor 7) and 12 row labels from 16 literals (floor 12) — exactly the post-D4b numbers the issue specified. check_render_keys.py and check_screen_vocabulary.py clean.
Frozen base. Structural, not incidental: App::render_key returns as soon as drawer_key() answers, so key.map is None under either sheet and enabled + committed are the only base-derived bytes. Asserted directly in the new test.
Geometry. MAX_SHEET_H 244, MAX_ROWS = (244 − 24) / 44 = 5, and Page::Root.height(&MAP) = 24 + 5×44 = 244 — exactly the bound, asserted at context_drawer.rs:1147. The last row's box is 264..304 on a 320 px panel. ROW_H, SHEET_PAD, EDITOR_H, OPEN_MS, SLIDE_MS, STEP_MS untouched; MAX_SHEET_H appears nowhere outside context_drawer.rs, so the quick drawer is unaffected.
i18n and the two budgets. The width test's switch_room = 204 − 14 − 54 − 8 = 128 matches the draw exactly: draw_root puts the label at area.x + 14 in an rx.w − 36 area, and toggle_slider puts the 50 px track at area.x + area.w − 54. door_room = 164 matches the chevron at right − 18. Both are pinned by assert_eq!((door_room, switch_room), (164, 128)), so a geometry change breaks the test rather than silently widening the budget. All four [map_context] labels differ from English in de/fr/es, and tests/i18n.rs renders both sheet states in all four columns — 7 passed.
Snapshots. I expanded $lang over every --png "$OUT/…" in ui-snapshots.sh and diffed the result against the manifest's filename column: 311 = 311, zero difference. The manifest diff is exactly 4 removed (ride-context-{live,de,fr,es}), 10 added (5 map-context*, 5 map-display*), 3 changed (ride-context, display, display-idle-return). 305 → 311 as specified. p p p p b is a proven Statistics recipe (statistics.png:430), so the re-shot ride-context.png really does cover the unchanged four-row RIDE table; B u p d p p opens the picker per idle_return_picker. I did not re-shoot — the two recipes I doubted are settled by existing recipes and an existing unit test.
Exclusions. No map.rs change. No editor row on either map table. No settings-codec change: settings.rs is not in the diff, so VERSION stays 18, MIN_SUPPORTED 16, and offsets 81/82/112 stay pinned. No central-list re-index. No waypoint_mode / units / idle_return migration. No settings/weather.rs, settings/bike_type.rs or UP_AHEAD touch. Docs live in their own docs: commit (786c865f).
Suites I ran (read-only, in the implementer's worktree). cargo test -p obc-app --lib — 968 passed, 0 failed. cargo test -p obc-app --test i18n — 7 passed. cargo test -p obc-sim --test dirty_parity — 9 passed. The three Python guards. I did not rebuild the board, re-run the sweep, or re-derive the resource figures; on the three moving link-level numbers I accept the PR's framing — the exact-match gate (compile_time_allocations.app) and both resource_guard.py invocations pass, and CI's embedded job is the authority the baseline file itself names.
Verdict: APPROVE
Remove the two struct-update asserts that cannot fail while a drawer is up (the key's early return leaves every other slot None on both sides), correct the German door-label comment to what the sheet actually draws, and register toggle_slider as a vocabulary landmark so a fourth slider declaration fails the guard.

Closes #1585. Part of the two-drawer grammar, epic #1515 (slice D4c). Lands on top of D4b (#1581 / PR #1583) and rebased onto develop at
948d5e7c.What this changes
Three switches that do nothing except change what the Map draws — the
HH:MMclock pill, the scale bar and the contour layer — used to live two levels inside the central Settings tree, on a page the rider could only reach by leaving the map. They are rows of the map's own contextual sheet now, which is the only home they have.The Map declares its own table.
Screen::Mapreturns the newMAPmenu: the ride's four secondary actions (Up ahead, Detour, POIs, Routes) in the same order, with the same predicates and the same destinations, plus a fifth row, Map display. Statistics, Climb and Ride control keep theRIDEtable byte for byte. A test pins rows 0-3 ofMAPequal toRIDElabel for label and action for action, so the ride actions cannot drift apart per view.The fifth row swaps one sheet for another. Pressing Map display replaces the sheet with a three-row sheet of switches. The new sheet is built by
ContextDrawerScreen::swapped_in, which stamps the open animation as already spent, so the shorter sheet is fully landed on the frame the press produced — a sheet that is already on the panel does not make an entrance. That frame, and only that frame, draws the screen underneath: the shorter sheet gives back a band still holding the taller sheet's ink. So the swap costs exactly one map render, the same as any other row's destination. Back closes the display sheet onto the Map, not onto the sheet above it, which is the rule every context row already follows.A switch row is the fourth row shape.
ContextAction::Toggle(ContextToggle)flips aboolin place and returnsTransition::None: the sheet stays up, the row draws the settings tree's own 50 × 28 slider instead of a chevron, and no other pixel changes. The rider sets all three in one visit and the frozen map behind is drawn again once, when the sheet closes. That is the point of doing it this way — a nested sliding page over a map would have cost a map render per frame of the slide.What is deleted
settings/display.rsloses the Clock, Scale bar and Contours rows — their constants, their press arms, their draws and their three tests (~110 lines). It keeps the idle-return picker, which governs when the whole UI returns to Home or the Map and is therefore device-global, not map chrome. The Display root row of the Settings list is untouched; no index moves.[display]catalog keys (clock,clock_sub,scale_bar,scale_bar_sub,contours,contours_sub) leave all four languages; four[map_context]keys arrive. Six out, four in, per language.toggle_slidermoves fromscreen/settings/mod.rsintoscreen/vocab/rows.rs, because it now has two homes;power.rs,bluetooth.rsand the drawer import it from there.ride-context*.pngframes are renamedmap-context*.png.After this,
Settings::map_clock,Settings::map_scale_barandSettings::map_contoursare each written by exactly one place in the tree, andtools/check_one_home.pyis what keeps it that way (floors raised 8 → 12 row labels, 4 → 7 drawer-written settings).The orchestrator disposition, for the owner to confirm
The five-row sheet and
MAX_SHEET_H240 → 244 (MAX_ROWS4 → 5) implement the disposition recorded on issue #1585, which the owner may veto. The Map needs the ride's four actions and its three display modifiers; seven flat rows are 332 px and fit no sheet at any height. Five rows is 244 px of the 320 px panel, leaving 76 px of map. The alternative that needs no geometry change would trade the Map's Routes or POIs row for Map display, which costs a documented mid-ride flow an extra hop and makes the same chord show different rows on the Map than on Statistics. A bounded scrolling sheet is #1515's remedy for real overflow and a much larger slice. Nothing the rider can do today is lost, and every script that walks rows 0-3 still works.If vetoed, the edits are: the
MAPtable's row list, the twoMAX_*constants staying put, and four re-scripted frames.What did not change
Settingsgains and loses no field:VERSIONstays 18,MIN_SUPPORTEDstays 16, the three fields keep their pinned offsets (81, 82, 112), no codec change and no golden pair — they are re-homed, not removed.RenderKeygains no field either: all three settings are device-only (no BLE adopt writes them), so under an open sheet only the rider can move one and only the selected row's, which meansDrawerKey::committedalready carries every state change andselectedevery cursor move. What the Map draws is untouched — this slice moves where the switch lives, not what it does. The contour switch is still provisional (#1096); it migrated, it was not retired, and #1097 still decides its fate.The Display screen is now a single-row page. Whether a one-row group still deserves its own screen is a Settings-tree question; answering it here would re-index the root list, which is D4b's alone.

the_map_declares_the_ride_actions_plus_its_own_display_row(harness) — the Map declaresMAP, its three siblings declareRIDE, rows 0-3 are equal, and no screen declares the display sub-sheet.a_toggle_row_flips_in_place_and_keeps_the_sheet— each of the three flips both ways, returnsTransition::None, leaves the page on the root, leaves the other two fields alone, and moves the key'scommitted.the_display_row_swaps_the_sheet_and_back_lands_on_the_map— row 4 replaces the sheet, the new one is landed on its first tick and asks for no open steps, its first frame reportsneeds_base()and the next does not, and Back returnsPop.a_flip_under_the_sheet_moves_only_the_drawer_key(render key) — with the display sheet over the Map:key.mapisNone, a camera move and a fix change move nothing, a flip moves the key only throughcommitted, and the close is exactly one invalidation.the_map_sheet_reaches_all_three_settings_and_survives_a_reboot(harness) — app level, through the real chord: the fifth row opens the display sheet, all three flips write their fields, each arms a persist on its own pass (a drawer is not a settings subtree), and the encoded blob restores all three into a fresh App. Replacescontours_toggle_persists_across_reboot, keeping its Elevation EL10c — device Settings toggle for contours (provisional) #1096/Elevation EL10d — on-glass review: keep or drop contours #1097 provenance.Extended:
pinned_by_the_row_tables(both tables join the list,MAX_ROWS4 → 5 with the derivation),every_label_and_choice_fits_the_sheet_in_every_language(both tables, and a second row budget — 164 px for a door, 128 px for a switch, because the slider takes 36 px more than a chevron),the_map_table_is_the_ride_table_plus_one_door,exactly_the_riding_views_and_the_timeline_declare_a_context,tests/i18n.rs's four-language walk, anddisplay.rs'sidle_return_picker.Checks run

obc test full(nothing cross-cutting changes),obc suites check(no suite, workflow or registry change — the tests land in existing files), wake-profile isolations (no wake or scheduling behaviour changes; the sheet's cadence constants are untouched), the iOS / web / desktop surfaces, any mutant demonstration, and all on-device / flashing / HIL / on-glass work (owner ruling, 2026-08-30). CI is the gate.Snapshots
One sweep, on the final code head, re-pinned in the same push. 305 → 311. The accounting is exactly what the issue predicted, and nothing else moved:
ride-context-live.png,ride-context-{de,fr,es}.png, renamed rather than lost.map-context.png,map-context-live.png,map-context-{de,fr,es}.png(the renamed recipes),map-display-sheet.png,map-display-clock-off.png,map-display-sheet-{de,fr,es}.png.ride-context.png, re-shot over Statistics (p p p p b C), which is what keeps the unchanged four-rowRIDEtable covered at all;display.pnganddisplay-idle-return.png, following the one-row page. The second is also a corrected recipe:B u p d p d d ppressed Contours, not the picker the filename has always claimed, so it is nowB u p d p p.detour-*,routeswap*and the simulator's reroute demo, all of which walk rows 0-3 of the map's sheet.One honest note on
map-display-clock-off.png. The issue expected it to show the sheet redrawing while the map does not; the frame shows the map's clock pill gone as well. That is the headless path being honest, not the frozen base failing:--pngcomposes the whole frame from nothing, so it never claims a resident frame and draws the base as always (ui_runtime::sheet_only). On the device the map keeps the pill until the sheet closes. The recipe comment now says this instead of the claim I could not support from the frame.Measured resources
One head build in
firmware/obc-fw-nrf54l, compared against the recordedresource_baseline.json. The base was not rebuilt.compile_time_allocations.appresource_guard.py reportsays "allocation report matches baseline".uninitpoll_frame_measured.bss+.dataresidual_stack_measuredmeasured_flash(a record, not a gate)resource_guard.py boardandreportboth pass.The three moving figures are link-level records measured on a different host from the one the baseline was recorded on (this is macOS/arm64; the baseline file itself names the CI
embeddedjob as the authority formeasured_residentandmeasured_flash, and a third pinned host for the itemisation). I am not claiming a cause for them: I did not rebuild the base and cannot separate this slice's contribution from cross-checkout toolchain drift. The one arithmetic relation worth stating is that resident grew and residual stack shrank by the same 472 B, which is what the linker does when.bssgrows into what is left over — that is a mechanical identity, not an attribution. CI'sembeddedjob is the figure that matters.Struct sizes, measured on this head:
size_of::<Screen>()= 104, unchanged. No variant added or removed.size_of::<RenderKey>()= 304, unchanged. No new key field.size_of::<ContextAction>()= 2, unchanged —ContextToggleis fieldless, so the row tables gain no.rodataper row.size_of::<ContextDrawerScreen>()= 32. The newuncovered: boollanded in padding the struct already carried; it is far inside the 104 BScreenslot.No
_compile_note_d4c_1515was added, because no allocation figure moved.One deviation from the issue text
ContextToggle's three variants keep theMapprefix the issue specifies (MapClock,MapScaleBar,MapContours), which tripsclippy::enum_variant_names. Rather than rename away from the spec, the enum carries an#[allow]with its reason: each variant is named for theSettingsfield it binds to, soreadandflipcan be checked by reading them side by side.🤖 Generated with Claude Code
