Depends on #216 (base frlg/stage4-cerulean, merged in at 831a22c; the diff shows only this change).

Adds FRLG AutoStory checkpoints 00.17-00.20: Route 25 to Bill, the S.S. Ticket, back to Cerulean's Pokemon Center, and an Oddish for Cut.

• 00.17, Route 24 (11, 15) east to inside the Sea Cottage (7, 8): fights the four Route 25 trainers the path can't avoid (Hiker Franklin, Picnicker Kelsey, Hiker Nob, Lass Haley), each on a step into their line. It only crosses the sight of the look-around Youngster Dan and the walking Youngster Chad on legs to walls or one-tile legs, and never where they could block the path after walking up.
• 00.18, Sea Cottage (7, 8) to Route 25 (51, 5): talk to the Clefairy from below, answer YES, use the PC from (4, 6), then talk to Bill from (6, 6) for the S.S. Ticket and leave.
• 00.19, Route 25 (51, 5) to Cerulean Center (7, 4): goes back by Route 25's south path and Route 24 east of the bridge, hops Cerulean's north ledge at (27, 1), then heals at the Center.
• 00.20, Cerulean Center (7, 4) back to it: buys 7 Poke Balls, crosses Nugget Bridge, west to the cliff and down to Route 24's grass at (3, 19) (out of Camper Shane's sight even when the leg west ends a tile short, console B m63), catches one Oddish with the CAPTURE step (30 battles, 7 balls at most), heals. Battles keep Wartortle in; the Oddish goes in only if the lead faints. A stopgap for console B's save: a new playthrough should catch a Rattata on Route 1 or 22 early instead and drop this row.
• TEACH steps can use a move tutor (item = "tutor"): talk, YES twice, then the same party-menu prompts as a TM.
• 00.14 (new playthroughs only; console B's save is past it) now visits Route 4's Mega Kick tutor: from Mt. Moon's exit up through (48, 5) into the tutors' pen to (50, 4), facing the tutor (50, 3), Mega Kick over Withdraw, then east to Cerulean as before. Cerulean can't walk back there without Surf. The Simulation test "00.14 from Mt. Moon to the Mega Kick tutor" walks it (red before the row change).
• Image tests: TeachScreenReader's frames drop their NN_ prefix, and the battle-loop tests take True/False and Hp<Color>_<hp>of<max> from the file name. The images are in PokemonFRLG: Mt. Moon onward AutoStory images CommandLineTests#9 (stage-1 readers' in BBQ Farmer: check which quest a reroll pays for, and that it was replaced #8; PokemonSV: test the Blueberry quest detector on reference frames #7 is closed).
• Adds the four trainers to STORY_TRAINERS (default risk LOW). The save card now knows Route 24 and Route 25.
• 00.18 walks around Bill to (7, 8) before leaving by the mat: after his scene he stands on (7, 6), and the old walk out bumped him and ended beside the mat (console B, 2026-11-03); the Simulation test "00.18 out of Bill's Sea Cottage" reproduces it.
• A hold over a step onto a connected map is a tile longer (RouteStep::connection_steps, LegSpec::stalled_steps): on console B such holds ended a tile short (00.14, 00.16, 00.20 onto Nugget Bridge). The overworld sim now stalls a tile on that step; the 00.20 Simulation test was red without the walker change (ended on Route24 (10, 20)) and passes with it.
• A GRIND or capture that paces now reports both of its tiles, and the next ROUTE first holds to walls that bring them to one (the walker's re-anchor search), then plans from there: console B's 00.20 (run m61) caught the Oddish on the far step, (3, 19), and the walk back planned from (4, 19) ran into a beaten Lass on the bridge. The Simulation test "00.20 back to the Center, the Oddish's battle on the pace's far step" was red (no fade onto the Center's warp) and passes; "the routes after pacing, from either of its tiles" walks the routes after 00.14b's, 00.15's and 00.20's pacing from both tiles.
• Pacing (CAPTURE and GRIND) now fights a trainer who sees the player, logs "trainer battle during pacing", walks back onto the patch from either pacing tile and goes on; before, Camper Shane's message stopped 00.20's capture with "no-battle-not-overworld" (console B m63). The Pace Sim test "a capture paced in a trainer's sight" was red (no wild battle in 200 steps) and passes.
• Test changes: a one-tile leg may cross a look-around trainer's sight. The row and trainer counts and the run plans are updated.

Testing

• Local build, --command-line-test-mode with CommandLineTests BBQ Farmer: check which quest a reroll pays for, and that it was replaced #8 + BBQ Farmer: let the exclusions table reroll quests the farmer cannot do #9 checked out: all PokemonFRLG and Pokemon::StorySteps tests pass, including the Simulation tests for 00.14's tutor walk, 00.17 and 00.20, TeachScreenReader and AutoStoryBattle on the renamed images. The one failure is ItemListReader's ItemsPocketMoonStone_eng.png (FileException: the image is in no CommandLineTests branch).
• Code health: 0 failures.
• Not yet run on the console.
