Stage 5: bosses that move, attacks that warn, and a second boss
ci / verify (push) Successful in 49s
Boss movement is a property of the PHASE, not of the boss -- a fight that
stands still and then starts hunting you is one boss with two phases. Four
modes (STATIC, ORBIT, CHASE, WAYPOINTS) handled generically in
SimWorld._move_boss, so a boss that moves is still data. BossDef.stationary
is gone rather than kept beside the phases: a flag claiming the boss stood
still while a phase walked around would be a second source of truth and the
wrong one, so moves() is derived.
CHASE holds a distance instead of closing, because a boss standing on top of
you is a boss whose bullets cannot be read. Waypoints are fractions of the
arena so one phase works in rooms of different sizes. Every mode is speed
clamped in one place -- ORBIT computes an absolute destination and would
otherwise snap onto its circle on the first tick -- and movement slides
against geometry so a boss cannot walk through the pillars its own arena was
designed around.
The room clamp moved to after movement, where it is finally load-bearing. It
was a no-op while every boss stood still, which is exactly when an invariant
is cheapest to establish: boss rooms deliberately do not lock, so walking out
is always an escape, and that only holds if the boss cannot follow.
TelegraphedStrikeEmitter marks spots and fills them a moment later. The moment
between is the feature: a burst at your feet is a coin flip, the same burst
with a second of notice is a question. It stays stateless like every other
emitter -- they are shared resources and two bosses of the same kind must not
stomp each other -- so strike positions are derived from the volley number and
a test asserts the burst lands where the marker promised. Markers are drawn
through fog and through walls, unlike everything else in the view, because a
warning you cannot see is an unavoidable hit with extra steps.
The Cantor of the Vault fights in the choir vault: static, then a four-corner
circuit, then a chase, then orbiting while marking. It exists to prove the
format stretched, and a test asserts it uses both new mechanisms.
Which boss a run has now comes from its SEED rather than its depth. Depth is a
dev flag nothing in play raises, so the arena was keyed to something no player
can change and the second boss was unreachable in an actual game.
Two things found while finishing:
- tools/export_content.gd had a hand-maintained boss list and had already
gone stale, silently not writing the Cantor. Content.ALL_ENEMIES and
ALL_BOSSES now feed the export tool, the renderer and five tests that each
kept their own copy.
- diag_loot failed intermittently after another diagnostic. Taking over from
the bot cleared its input queue but not its HELD input, so a starved server
coasted on the bot's last movement vector for half a second and walked the
player off the item it had been placed on. The press arrived correctly,
which is why "the press reached the simulation" passed while everything it
should have caused failed.
check.sh clean, 409 tests, SMOKE PASS (19 assertions), all four diagnostics
green.

Scale health and damage by ten so percentages have somewhere to land
A shot is 60, a fresh character has 1000, the Warden has 36000. Enemy health, boss health and every emitter's damage were scaled with them, so every ratio is unchanged and time to kill is exactly what it was -- tests/unit/test_content now pins shots-to-kill per enemy and hits-to-kill a player so a careless edit to either side shows up as a number a designer recognises. The reason is rounding rather than balance. Damage is an integer, and at a base of 6 the +5% every upgrade carries computed to 6.3 and rounded straight back to 6: a player took their first upgrade, was told it made them stronger, and nothing happened. diag_upgrades used to print "damage matches the formula (6 -> 6)"; it now prints (60 -> 63). The boss's per-phase armour multiplier had the same problem, turning 1.15 into an effective 1.17. The practice dummy stopped relying on a huge health pool at the same time. Its old 100000 was already past the u16 the snapshot sends enemy health in, and once a shot did 60 a patient player could have destroyed the hub's only practice target for everyone until the next restart. EnemyDef.indestructible says what was actually meant, and a test asserts nothing else uses it. check.sh clean, 364 tests, SMOKE PASS, all four diagnostics green.

Stage 4: upgrades, and a quartermaster to spend them at
ci / verify (push) Successful in 48s
Every level banks one choice. Choices queue, and are spent at an NPC in the
hub: walk to it, press E, take one of three weighted options. Seven upgrades,
all data — split shot, glass cannon, spread, sniper, doubleshot, poison,
eraser — and SimWorld gained no per-upgrade branch to run any of them.
The four ambiguities in the brief were settled with the user first, since
each changes what gets written:
damage base x (1 + sum additive) x product multiplicative. The flat
+5% every upgrade carries, spread's -10%, doubleshot's -50%
and glass cannon's +100% pool; sniper multiplies on top, so
two snipers is 4x and not +200%.
glass half the LEVELLED maximum, multiplying if taken twice, so the
price does not fade to a rounding error by level 15.
poison independent stacks, not a refresh.
split +/-45 degrees from the original heading.
Independent poison stacks sound expensive and are not: every dose lasts the
same number of ticks, so doses expire in the order they were added, the
pending expiries are a plain FIFO, and PoisonTrack only ever looks at its
front. O(1) per actor per tick however many are live.
Stats are derived from the upgrade list and never stored, the way level is
derived from experience -- a saved stat cannot disagree with the upgrades
that produced it. Upgrade riders (split charges, poison, erase chance) travel
on the bullet instead, because a shot in flight has to keep what it was fired
with rather than gaining Poison because the shooter just took it.
Two invariants this collided with, both now pinned:
- bullet speed gained a ceiling. Wall collision samples once per tick, so
anything over a tile per tick tunnels; two snipers asked for 2480 u/s
against a 1920 threshold, and a tunnelling bullet looks like a bullet.
- BULLET_INTEREST_RADIUS rose to 2900, because an upgraded player shot is
now the longest-travelling bullet in the game. test_interest measured
the worst case from static content, which upgrades quietly invalidated.
Choosing is intent checked three ways: a choice must be owed, the index must
name one of the three options the SERVER put on the table, and the player
must be standing at the NPC. The offer is rolled once and persisted, so
closing the screen is not a reroll and neither is a crash.
tools/diag_upgrades.tscn covers level -> banked choice -> refused in a
dungeon and refused across the room -> taken at the NPC -> new stats ->
on disk. Bots never walk to the quartermaster, so the smoke test cannot.
Known gap recorded in the roadmap: at PLAYER_BULLET_DAMAGE = 6, the +5% the
first upgrade carries rounds back to 6 and visibly does nothing. It comes out
right in aggregate, but the fix is a balance edit across content.gd and so is
the user's call.
check.sh clean, 357 tests, SMOKE PASS (18 assertions), all four diagnostics
green.

Add a second dungeon: the Proving Grounds, a test harness you walk into
ci / verify (push) Successful in 47s
Two labelled portals now stand side by side in the hub. The Proving Grounds runs the same generator, the same rooms, the same enemies and the same four-phase Warden -- enemies at a fifth health, the boss at 288 instead of 3600, and trash dropping potions 80% of the time instead of 8%. A manual pass over loot, the inventory, dropping and every boss phase takes a couple of minutes rather than a quarter of an hour. It is multipliers over the shared content rather than a parallel copy: a duplicated Content would drift the first time anything was tuned, and "identical but easier" would quietly stop being true. And it is a portal rather than a launch flag, so the two can be compared back to back without restarting the server -- which is most of the point. Which dungeon you enter is resolved from the player's server-side position, and PORTAL_USED carries the answer. There is deliberately no client message that names a dungeon: one would let any client ask for the generous loot table and bring the results back to the hub. Instance matching compares dungeon ids too, so walking into one entrance can never drop you into the other's run on timing alone. SimWorld.portals replaces portal_pos/portal_enabled, enter_instance carries the portal list and the dungeon id (the client needs the latter to scale the boss bar's ceiling the way the server scaled the boss), and Protocol.VERSION goes to 7. Also pins what happens when two players reach for one item on the same tick: exactly one gets it -- the loop is sequential and the pickup erases the entity before the next player looks. The tie-break is join order rather than distance, which is arbitrary rather than designed, so it is recorded as such. Stale doc fixed while here: MapGen.build() still claimed the client rebuilds the map from the seed, which has not been true since map streaming landed and is the opposite of the rule. check.sh clean, 288 tests, SMOKE PASS (18 assertions, both dungeon kinds opened over a real socket), all three diagnostics green.

Stage 3: inventory, ground loot, and two loot visibilities
ci / verify (push) Successful in 48s
Four always-on-screen slots, items as data, and loot tables on enemies and bosses. Health potions drop rarely from trash and always from the Warden; the Warden also drops a Warden's Ration, one per living player, which does nothing at all. The ration is not filler. Player-instanced loot is a separate code path from shared loot -- a distinct entity per owner, filtered per peer in the snapshot encoder -- and the cheapest way to keep that path honest is to have something in the game that exercises it on every boss kill. Item actions ride the input frame rather than becoming new client messages. InputFrame gained BTN_USE, BTN_DROP and a slot byte, which buys the packet-loss redundancy, the replay guard on last_input_tick, ordering against movement on the same tick, and a rate limit of one action per tick -- all of which a separate RPC would have needed bolted back on. The cost is that anything in the frame which must not repeat has to be edge-triggered, since frames are resent and a starved server coasts on the last one it holds. Instanced loot is enforced in NetCodec.encode_snapshot, beside the actor interest radius: a peer is never told another player's copy exists. Hiding it client-side would have been the same mistake as relying on fog to hide enemies. Inventories live on the character and are written to the store on every transaction, so a crash between "picked it up" and "wrote it down" cannot lose or duplicate an item. Anything dropped becomes world-shared whatever it was before, and a potion used at full health is refused rather than spent. tools/diag_loot.tscn covers drop -> snapshot -> pick up -> persist -> use -> drop plus both visibilities on the wire, for the same reason diag_progression exists: bots are poor shots and almost never produce a drop. It asserts each input frame was actually consumed, after an early version silently dropped its first press and every later check passed for the wrong reason. check.sh clean, 266 tests, SMOKE PASS, all three diagnostics green.

Documentation pass before context compaction
ci / verify (push) Successful in 47s
The roadmap was actively misleading: an earlier stage renumbering left Stage 2's completed work sitting under a "Stage 3 -- todo" heading, and the inventory table orphaned with no heading at all. Since that file is the primary handoff document, a fresh session would have started by re-implementing accounts and characters. Rewritten. Captured in full, from the original brief rather than from memory, the two stages not yet built: - Stage 3 (inventory and loot): 4 slots, potions rare from trash and guaranteed from bosses, world-shared loot, and the player-instanced food item -- with a note that two loot visibilities must exist from the start, because proving the instanced path works is the food item's entire purpose. - Stage 4 (upgrades): every upgrade with its exact stated effect, plus the two constraints it will collide with -- sniper's 2x bullet speed against the tunnelling threshold, and per-player bullet travel against the interest radius that test_interest.gd currently derives from static content. Ten open questions are listed as explicitly do-not-guess, seven of them blocking Stage 4. ARCHITECTURE.md still claimed "the arena is a rectangle" and "no tilemap collision", both untrue since Stage 1. Rewritten around MapGrid, with what the grid costs (axis-aligned, 32px-quantised, bullets under a tile per tick) rather than only what it buys. Added a "verification traps" section to WORKFLOW.md recording six mistakes made during this work, each of which cost a round trip of reporting something fixed that was not: verifying the artefact rather than the behaviour, dumping the wrong channel, measuring a configuration where the bug cannot exist, a test whose setup silently invalidated it, git checkout reverting real work alongside a probe, and a pattern edit matching in two files. They are specific enough to be actionable. Also documented the diagnostics in CLAUDE.md -- they were undiscoverable -- and recorded the current verification surface so "everything passes" has a stated meaning. 206 tests, 15 smoke assertions, both diagnostics pass. |

Hide dead characters, suggest names, make the XP bar live
ci / verify (push) Successful in 46s
The roster sent to clients now contains living characters only. Retirement stays server-side bookkeeping for archival; from the player's side a dead character is simply gone, and listing it offers a choice that cannot be taken. The XP bar only moved on a level-up or a character swap because it read the character roster, which is re-sent only when the SET of characters changes. Experience now rides the snapshot -- four bytes on a message already going out at 20Hz -- and the server mirrors each grant into the world immediately rather than only when a level is crossed. The create field starts with a suggested name instead of blank, and offers another after each creation. Two bugs found while testing, both mine: The first was a bad patch of my own: a change meant for the snapshot decoder also matched inside decode_characters, which then read a four-byte field its encoder never wrote and ran off the end of every packet. This is precisely the "encodes but decodes wrong" failure the codec tests exist to catch, and it was caught within a minute of the test being written. Chasing that exposed a real robustness gap: StreamPeerBuffer.get_utf8_string() pushes an engine error and returns garbage when the buffer is short, so a truncated or hostile character/roster packet produced error spam instead of degrading. Both decoders now bounds-check every field, with tests that slice each packet at many lengths and assert it degrades rather than inventing entries -- the same guarantee the input decoder already had. 206 tests. check.sh, test.sh, smoke.sh and both diagnostics pass. |

Hub character swapping, XP percentage, passive health regeneration
ci / verify (push) Successful in 47s
Character swapping is hub-only, and refused by the SERVER rather than merely greyed out in the menu. Allowing it inside a dungeon would be an instant, uninterruptible exit from danger -- strictly better than the one-second escape channel, which would make that channel pointless. Creating a character in a dungeon is refused for the same reason. Both are covered by diag_progression. Health regenerates at 0.5% of MAXIMUM per second. A percentage rather than a flat rate so it does not become irrelevant at level 15: a capped character regains 1.2 hp/s against a level 1's 0.5, and both take about 200 seconds to heal from nothing. No out-of-combat gate -- at this rate it cannot out-heal anything actually shooting at you, and a trickle that never stops is easier to reason about than a timer players have to learn. A fractional carry is needed because a tick heals well under one hit point, so truncating each tick would heal exactly nothing; there is a test for that specifically. The XP bar now states the percentage and the level it leads to, since a bar answers "how far" vaguely and a number answers it exactly. Recorded the two Stage 3 answers: 4 inventory slots, and the boss's food item is player-instanced now so the mechanism gets exercised rather than deferred. Writing the swap guard's test caught my own mistake: the first version created its spare character through the store, which has no opinion about where you are, so it bypassed the guard it was meant to prove and left a stray character behind that broke a later assertion. 200 tests. check.sh, test.sh, smoke.sh and both diagnostics pass. |

Stage 2: accounts, characters, permadeath, levels and experience
ci / verify (push) Successful in 47s
Identity is shaped like Steamworks so swapping to it is one subclass and no schema change: the client presents an opaque ticket, the server validates it into a stable 64-bit account id, and nothing downstream sees anything else. LocalAuthProvider takes any ticket at face value -- insecure on purpose, and labelled as such everywhere, because the point is the shape rather than the security. Do not ship it. Characters persist as JSON keyed by account. Account ids are written as decimal strings because they are 64-bit and JSON numbers are doubles, which would silently round them. A corrupt store aborts the server rather than starting empty: starting empty looks like it worked and then saves over every character on the first level-up. Levels 1-15, +10 max health each, level DERIVED from lifetime experience rather than stored beside it, so a hand-edited save cannot produce a level 12 character with a level 3's experience. Experience is shared undivided across everyone alive in the instance -- splitting it would make bringing a friend cost you progress. A level-up heals by what it added, so gaining one mid-fight is relief rather than a bar that moved further from full. Death is permanent and unbinds the character entirely: no "return to the hub as the character who just died", because the run is over. The record is retired, never deleted. The five-character cap counts LIVING characters only -- counting the dead would lock a player out of their own account after five deaths. Verified by tools/diag_progression.tscn, which drives the real server through kill -> xp -> level -> health and death -> retire -> roster. The bot smoke test cannot cover that: bots are poor shots and rarely kill anything. Writing it caught two real ordering bugs -- the death event was dispatched before the payload that tells the player they died, and the dead character stayed bound to the peer. Also added --account and --store so several clients and test runs can coexist on one machine. The smoke test now uses a scratch store; without it a rerun resumed the previous run's characters and "a character was created" quietly stopped being true. 193 tests. check.sh, test.sh, smoke.sh, diag_progression and diag_prediction all pass. |

Fix black wall tops, pillar art, player anchor, and whole-sheet bullets
ci / verify (push) Successful in 46s
Bullets rendered as the entire sprite sheet, which was the clue that named the cause: a MultiMeshInstance2D cannot show a sub-region of a texture. Its mesh UVs run 0..1 across whatever texture it is handed, and an AtlasTexture does not help -- the draw resolves to the underlying atlas and the region is discarded. Frames are now pre-sliced into 32 standalone 16x16 textures at startup, so each frame is one texture assignment per kind and no region is involved. My previous two attempts fixed the atlas contents while the renderer was structurally incapable of showing one cell of it. Black voids above walls: wall_top_mid has 12 of its 16 rows transparent. It is a cap meant to be laid over a wall, not a tile, and drawn alone it was three quarters nothing. Floor is now drawn beneath every tile so transparency shows ground rather than clear colour, the wall face is drawn from the opaque wall_mid, and the cap is overlaid only where open floor lies above. Pillars used a wall segment and read as stray blocks; they now use the column tile, which looks like something you walk around. The player hitbox appeared at the head because it was: the knight occupies rows 8..27 of a 28-row cell, so anchoring on the cell centre put the draw origin about 4px above the body's centre. Added a per-sprite anchor offset that cancels it, with a test that recomputes the offset from the art so a re-cut sheet fails rather than silently misplacing the character. Tests pin the two tileset facts that caused this: the cap is mostly transparent (so it may never be drawn alone) and the wall face is fully opaque (so it may). 166 tests. check.sh, test.sh and smoke.sh pass. |

Fix idle/run animation flicker and bullet cell bleed; add F1 hitbox overlay
ci / verify (push) Successful in 46s
The ship looked like it played both animations at once because it effectively did. is_moving() read the tail of `pending`, which _reconcile drains on every snapshot -- so it returned false about 20 times a second and the sprite alternated between the run and idle strips. Now reads the last sampled input, which survives the queue being emptied. Bullets were still wrong for a reason my earlier ASCII check could not see: I had dumped alpha only, and this pack animates as a colour shimmer over a fixed silhouette, so identical-looking frames told me nothing. The actual defect was that several sprites overflow their 16px cell and bleed into the neighbour below -- the first "heavy" I picked dragged in a solid slice of the sprite above it. Cells are re-picked to ones with empty borders in every frame, and build_local_assets.py now asserts that rather than trusting the choice, so a future pick that bleeds fails at build time instead of looking like a rendering bug. Added a hitbox overlay on F1 (src/view/debug_draw.gd). It draws what the simulation actually collides against over what is drawn: player hitbox against sprite radius, the muzzle point, enemy and boss radii, aggro rings, every live bullet's radius, and terrain outlined by which of the three flags each tile sets -- so a pit that stops feet but not bullets looks different from a wall. It deliberately ignores fog, since hiding half the evidence would defeat the point, and it reads every number from SimConfig/MapGrid/Content rather than keeping its own copies, or it would just confirm its own mistakes. Nearly every "that looked wrong" report in this project has been art and simulation disagreeing, and each took a round trip to diagnose. This makes that class of bug visible directly. 163 tests. check.sh, test.sh and smoke.sh pass. |

Fix bullet atlas, animation speed, sprite flip, fire rate, silent shots
ci / verify (push) Successful in 46s
Bullet sprites were wrong because I read the pack's layout backwards. Each of
its 8 PNGs is one ANIMATION FRAME, and a column within a file is a COLOUR
variant -- so walking columns cycled the palette while the shape sat still, and
the rows I picked were in a region of larger multi-cell sprites, which is the
scattered debris that showed on screen. tools/build_local_assets.py now composes
a proper atlas: 8 frames across, one row per SimConfig.KIND_*.
Animations ran at whatever the machine's framerate was, because they counted
_process calls. At 240fps that is four times too fast on its own, before the
requested halving. Both actor and bullet animation are now driven by elapsed
seconds, so they look the same on any machine.
The knight shifted sideways instead of mirroring: a Rect2 with negative width
does not flip, the draw call normalises it, so the sprite kept its orientation
and jumped right by its own width. Mirrored through the canvas transform about
the sprite's centre instead.
Shots were silent when a bullet spawned inside an enemy. The sound rode on
BULLET_SPAWN, which is deliberately suppressed for a bullet resolved and removed
within the same tick -- so no event, no sound, and this got more likely the
closer you stood. Firing is now its own event (PLAYER_FIRED): the shot happened
whether or not a bullet survived to be replicated. Protocol 3 -> 4, because
inserting mid-enum shifts the wire value of every event after it.
Fire cooldown 7 -> 14 ticks (4.3 shots/sec).
Licence question 2, confirmed verbatim: the paid tier DOES grant commercial use
("You may use these assets in personal, commercial or non-commercial
projects"), but its next sentence still forbids redistribution "no matter how
much you modify it". Paying moves these from local-only-and-non-commercial to
local-only-and-commercial; it never makes them committable. Only replacing them
with permissively licensed art does that.
Question 3: CREDITS.md now credits every pack, including the two whose licences
do not require it and the unused ones in considering_dont_use_yet/.
158 tests. check.sh, test.sh and smoke.sh pass.

Remove non-redistributable art from the repo; record licence terms
Researched the licence at each of the four itch.io sources. Two of the four
forbid redistribution, and publishing a repository containing them is exactly
that, so they are out of the tree.
0x72 DungeonTileset II CC0 1.0 commercial ok, no credit required
Helton Yan Pixel Combat CC BY 4.0 commercial ok, CREDIT REQUIRED
Fire Pixel Bullet 16x16 custom non-commercial, NO REDISTRIBUTION
750+ Effect and FX Pixel custom non-commercial, NO REDISTRIBUTION
Both bdragon1727 packs state verbatim: "You cannot do: Resell / redistribute
this asset." The FX pack's paid tier is no better for this purpose -- "You can
NOT re-distribute the file, no matter how much you modify it" -- so paying does
not unlock it and neither does editing the art.
bullets.png and impact.png therefore move to assets/local/, gitignored.
Art.bullets_texture() / impact_texture() load them at runtime and return null
when absent; the bullet renderer falls back to the generated dot it used before,
tinted per kind so bullet types stay distinguishable. Nothing there may be
preload()ed -- preload resolves at compile time and would fail the build on
every machine without the files, which is every clone.
Verified both ways rather than assumed: with the files present the game uses
them and no fallback triggers; with them moved aside, 156/156 tests pass and the
game runs clean on the generated dots.
Added CREDITS.md, because Helton Yan's CC BY 4.0 makes attribution a licence
obligation rather than a courtesy. A file in the source tree does not discharge
it once the game ships -- an in-game credits screen is now a tracked todo, and
flagged as a licence requirement rather than polish.
NOT addressed here, and it needs a decision: these files remain in git history

Replace placeholder rendering with real sprites and audio
Terrain, actors, boss and bullets are sprites now, and four sounds play off server events. 548KB total across seven files, out of 3.9GB of source packs. - src/view/art.gd holds every atlas rect and sound path in one table, copied from the 0x72 pack's own tile_list. Scattering coordinates through draw calls would make re-cutting the atlas a hunt, and a wrong rect invisible. - Bullets get one MultiMesh per kind rather than one overall: a MultiMeshInstance2D carries a single texture and each kind needs a different region of the sheet. Four draw calls, no custom shader passing UVs through per-instance data. - src/view/sfx.gd is a 16-voice round-robin pool. Bullet-hell fire rates mean sounds overlap constantly, and identical sounds landing within two frames are collapsed so a ring hitting eight bullets is a bang rather than clipping. Every sound is triggered by a server event, never a local guess, so what you hear matches what happened. Audio was converted, not copied: the pack ships 24-bit/96kHz masters averaging 2MB. Downsampled to 16-bit/44.1kHz mono, silence-trimmed, and the shoot sound hard-capped to 0.30s -- it came out at 2.03s, against a fire cooldown of 0.12s, which would have smeared held fire into noise. tests/unit/test_art.gd checks what cannot be eyeballed here: every atlas rect lands inside its texture, every animation frame of a strip fits (the last frame is what runs off the sheet, not the first), there is a sprite per bullet kind and per enemy visual, and no sound is long enough to stack badly. A wrong atlas coordinate does not error -- it silently draws the wrong pixels. Licence sources recorded in docs/ASSETS.md now that they are known. All four are free versions and four rows still say "confirm at source": free itch packs vary on credit and commercial use, and there is no credits screen yet. 155 tests (was 146). check.sh, test.sh and smoke.sh pass. |

Close Stage 1: per-peer actor interest, boss room confinement
ci / verify (push) Successful in 46s
The gap Stage 1 left open: snapshots were encoded once and broadcast to every peer in an instance, so clients were handed enemies the fog then hid. Fog is a rendering rule -- a modified client draws whatever it holds -- so that was no defence at all. Snapshots are now encoded per peer, and actors beyond ACTOR_INTEREST_RADIUS (800u) are never sent. Measured cost of four filtered encodes against one shared: 95.6us vs 24.9us, or 0.032 ms/tick amortised over the snapshot interval. Two asymmetries worth keeping: - The observer's own player record is never filtered, however far out the arithmetic puts it. The client reconciles its prediction against that record, so dropping it breaks the player's own movement rather than hiding someone. - Only bullet SPAWNS are filtered, never despawns. A client told about a bullet must always be told it died, or it keeps a phantom. Bullet spawns use a much wider radius (2200u) than actors, deliberately. An enemy appearing at the edge of sight is cosmetic; a bullet withheld at spawn that later flies into view is invisible damage. The floor is longest bullet travel + fog radius -- 1500 for the Warden's Collapse snipe -- and test_interest.gd recomputes that from live content, so adding a faster or longer-lived bullet fails a test instead of producing bullets that wink into existence. Also clamped bosses to their room. A no-op today since every boss is stationary, which is exactly when the invariant is cheap to establish: boss rooms have no door that locks, so the only thing keeping a fight in the boss room is the boss, and Stage 5's movement work would otherwise break it quietly. 146 tests (was 137). check.sh, test.sh and smoke.sh pass. Stage 1 has no partials left; docs/ROADMAP.md now records the three interest radii and the floor each must respect. |

Keep asset packs out of git and out of Godot's importer

The packs total 3.9GB, almost all of it Helton Yan's SFX shipped as 24-bit / 96kHz studio masters -- ~2MB for a single gunshot. Two guards, because they solve different problems: - .gitignore excludes the contents. The directory and its guard files stay tracked, so a fresh clone has the .gdignore in place before anyone drops packs back in. - assetpacks/.gdignore stops Godot descending into the tree at all. This is the urgent half: tools/check.sh runs --import, which walks all of res://, so the next check would have imported several thousand PNGs and 2,100 of those WAVs, and every run after it. Verified by controlled test rather than assumed -- an unguarded PNG under res:// imports and gets a .import file beside it; with .gdignore neither happens. check.sh stays at 3.3s and .godot/imported at 1.2MB. The trade the .gdignore buys is that nothing in assetpacks/ can be referenced from a scene or script. That is the intended shape: raw source on one side, game-ready files copied into res://assets/ on the other, so adding a huge pack costs the repo and the import step nothing. docs/ASSETS.md records attribution, because gitignoring the packs also gitignores their licence files. Worth flagging: four of the six packs shipped with no licence text at all, and two of the undecided ones are demo versions, which are often more restricted than the paid packs. Only RF Catacombs has explicit terms (public domain, no resale). Those rows need a source URL before anything ships. Also removed __MACOSX and .DS_Store extraction artefacts, and left considering_dont_use_yet/ untouched as the user's own "not chosen" marker. |

Fix aiming under a scrolling camera; add status and decisions docs
ci / verify (push) Successful in 46s
The aim bug was collateral from the camera work. "Mouse relative to the centre of the screen" WAS the cursor's world position while the world was drawn fixed at the origin, so subtracting the player position gave the right vector. Once the camera scrolled, that expression became the aim vector itself, and subtracting the player position again made the ship aim at a fixed world location -- walking around swung the crosshair with the mouse held still. Fixed by inverting the transform the view actually draws with (world = screen - world_view.position, published by the game scene each frame) rather than assuming the player is centred, so it still holds if the camera later clamps at map edges or gets shake or look-ahead. tests/unit/test_aim.gd pins it, including the regression directly: moving the player must not move the crosshair. Documentation, for other sessions picking this up cold: - docs/ROADMAP.md rewritten as the status map -- every feature in the brief against its state and the file implementing it, the known gaps called out (actor interest management is the notable one), and the ten design questions that are genuinely unspecified and should not be guessed at. - docs/DECISIONS.md, new: settled decisions with their reasoning, so a session does not re-litigate or re-ask. Several are not the obvious default -- no i-frames, no contact damage, non-interruptible escape, and never sending the map seed. - CLAUDE.md and README point at both. 137 tests; check.sh, test.sh and smoke.sh pass. |

Stage 1: tile maps, walls, fog of war, aggro, scrolling camera
ci / verify (push) Successful in 46s
Replaces the fixed centred arena with per-world tile geometry, which is the foundation the remaining features sit on. - MapGrid: tile grid with three independent flags -- blocks movement, bullets, sight -- so a pit stops feet but not bullets or eyes, and a barricade stops feet and bullets but not eyes. Circle collision with per-axis sliding, and Bresenham line of sight shared by fog and aggro. - MapGen: rooms and corridors generated from (seed, depth), with hand-authored boss arenas from Rooms stamped in first so a corridor can never carve through a designed fight. Reachability from spawn to boss is asserted over 40 seeds -- "usually connected" is the failure mode that ruins one run in twenty. - Dungeons are populated at creation, per room, instead of gating on waves. You explore and choose your fights; the run ends when the boss dies, not when the map is swept. Boss rooms have no lock, so walking out is always available. - Aggro: enemies need range AND line of sight, so a dungeon stays quiet until engaged and cover actually protects. - Hard fog, scrolling camera, and terrain rendering. Maps are streamed per peer in chunks around that peer's player, and the seed is deliberately NOT sent -- a client holding it could regenerate the whole dungeon, which is a map hack for free. Stream radius (900u) is wider than view radius (460u) because the client predicts movement against walls and simulates bullets that die on them; the accepted cost is a cheater seeing a little further than the fog, never the floor plan. Partial map knowledge means wall deaths must be announced rather than derived. A test caught the subtle half of that: out-of-bounds tiles read as WALL by design, so checking geometry before bounds reported every bullet leaving the map as a wall kill. 128 tests (was 103); check.sh, test.sh and smoke.sh pass. 0.26 ms/tick with 4 players and a boss, ~65x headroom. |

Unlock menu after failed join; remove contact damage; cover clean disconnects
ci / verify (push) Successful in 45s
A failed connection left the connect buttons disabled forever. _show_menu() returned early when a menu already existed, so the set_busy(false) that re-enables them never ran on the way back from _abort_connect -- the player was locked out of both joining and hosting with no way out but a restart. Also guards against a second attempt stacking on an in-flight one. Contact damage is gone as a concept: nothing in this game hurts you by touching it, because every threat should be a bullet you can see and dodge. The Stalker walked at you and dealt contact damage and nothing else, so it now carries a point-blank shotgun instead -- five pellets, 62 degrees, 18-tick lifetime for about 78px of reach, so it still has to close and leaves nothing lingering. tests/unit/test_content.gd asserts every hostile enemy has an emitter, so a new enemy cannot quietly reintroduce the mechanic. The menu's "Disconnect" DOES get the anti-cheese protection -- verified, not assumed. It calls Net.shutdown(), the socket closes, and the server takes the same linkdead path as a SIGKILL, because the channel is keyed on the socket closing rather than on how it closed. Made permanent: a --leave-after bot flag and two smoke assertions covering the polite exit alongside the hard kill, so a future "clean leave" message that skipped the channel would fail a test. The menu now says so out loud in a dungeon -- the mechanic only reads as fair if the cost is known before clicking. 103 tests, 12 smoke assertions; check.sh, test.sh and smoke.sh all pass. |

Fix permanent input-timing desync; no i-frames; UI respawn; guard dead joins
ci / verify (push) Successful in 45s
The real cause of the ship/bullet separation, which the previous commit only half-addressed. The server dropped inputs past a lead of 12 while the client only re-synced past 16, so a client whose lead drifted into 13-16 had every input silently rejected while believing its timing was fine. The server coasted on held_input and then stopped; the client kept predicting. The two separated permanently and the reconciler fought it every snapshot -- "shoved around". It needed two independent clocks to drift, hence "only after some time", and nothing in the loop could notice, hence "then persists". The listen-server diagnostic could never reproduce it: one process, one physics tick, lead constant by construction. Two defences: INPUT_MAX_LEAD (40) is now far wider than the client's correction band (3..20), asserted by tests/unit/test_input_lead.gd so narrowing it fails a test; and an ack-stall detector re-syncs when last_input_tick stops advancing, which catches the whole class regardless of cause -- lead alone cannot, because a wrong lead looks normal from the client. diag_prediction.gd now injects a +14 tick drift and exits non-zero unless the gap recovers. Also: - No invulnerability frames. Every bullet that touches a player lands; i-frames made dense patterns safer than sparse ones, which inverts the genre. Measured: a stationary player survives ~13.6s of the Warden's opening phase, ~17.5s drifting. spawn_grace remains the only invulnerable state. - Death is exited with a HUD button, disabled for the first 3s. The lockout is enforced in SimWorld, not just by graying the button -- a client that ignores its own UI still waits. The interact key no longer respawns. - Joining a server that is not there no longer drops the player into an empty lobby they cannot act in. Net.join() only creates an ENet object; the game scene now waits for the server to actually place us in an instance, with an 8s timeout, and headless runs exit non-zero instead of idling. Protocol 2 -> 3. 98 tests; check.sh, test.sh and smoke.sh all pass. |

Fix bullet/ship desync; rework death, escape, arrival and hub awareness
(1) Bullets appeared to trail the ship. Two independent causes, measured with
the new tools/diag_prediction.gd rather than guessed at:
- ServerRuntime ticked before ClientRuntime, so input sampled on frame N was
not consumed until frame N+1, leaving the drawn ship a constant one tick
(4.00px at 240 u/s) ahead of the authoritative one that bullets spawn from.
ClientRuntime now sets process_physics_priority = -10. Gap on a listen
server: 4.00px -> 0.10px mean, 0.30px worst.
- PLAYER_MUZZLE_OFFSET was PLAYER_RADIUS + 6 = 12px against a 13px drawn
ship, so bullets were born inside the sprite. Regression from the previous
commit's hitbox shrink; it now derives from PLAYER_VISUAL_RADIUS.
(2) No more timed respawn. A downed player stays down until they ask for the
hub (E), which is an ordinary input -- the server has no "revive me" message.
(3) Escape channel 3s -> 1s, and damage no longer cancels it. An interruptible
channel makes killing the process strictly better than using the button, so a
dropped connection now runs the same channel: the player stays in the world as
linkdead, still killable, and is only released once it completes. Instances
refuse to close while a linkdead body is resolving, or a solo drop would delete
it on the next tick and hand the exploit straight back.
(4) Escape opens an in-game menu: return to hub (routed through the same held-
escape channel, not a new message), disconnect, quit.
(5) Server pushes a roster so the hub shows who is online and which dungeon
they are in. Entering a dungeon grants 2s arrival protection -- invulnerable
AND weapons-cold, since invulnerability alone would make the spawn a free
firing position -- flagged in the snapshot and drawn on every protected ship.
(6) Cleared dungeons hold the party 30s (was 5s) with a visible countdown.
(7) The hub's grey circle was a 100k-HP target dummy that read as scenery. Now
drawn as a bullseye so its purpose is legible.
Protocol version 1 -> 2. 91 tests (was 78); smoke.sh gains a bot that is
SIGKILLed mid-dungeon to prove the disconnect path end to end. check.sh,
test.sh and smoke.sh all pass.

Fix lobby/HUD UI pinned at (0,0); shrink player hitbox below visual size
The lobby connect menu and three pieces of the HUD (hit-flash overlay, boss bar centering, death-message centering, hint label) were all silently broken by the same Godot gotcha: set_anchors_preset(preset) with the default keep_offsets=false does NOT zero the offsets to the preset's margins -- it recomputes them to preserve the control's *current* rect, which for a freshly constructed Control is (0,0). Anchors end up correct; the actual rect stays pinned to the top-left corner regardless. Fixed by switching to set_anchors_and_offsets_preset() everywhere a Control is built in code, and by using offset_left/offset_top (anchor-relative) instead of .position (absolute) for the HUD hint label. Documented as gotcha #5 in CLAUDE.md. Also split PLAYER_RADIUS into two constants: PLAYER_RADIUS (6.0, the authoritative hitbox used by SimWorld) and PLAYER_VISUAL_RADIUS (13.0, view-only, used by world_view.gd). The client renders every ship a little late relative to the server -- interpolation delay, reconciliation smoothing -- so a hitbox that matched the sprite would let bullets connect against a ship the player watched dodge clear of them. A smaller hitbox means the occasional bullet visibly clips the sprite without a hit, which reads as more forgiving of latency than the reverse. Verified headlessly: a throwaway scene instantiating MainMenu/HUD under a real 1280x720 viewport, asserting the panel is centered and _canvas.size / hint position resolve correctly, before and after each fix. check.sh, test.sh (78/78) and smoke.sh all pass. |

Initial commit: Transcience MVP
Top-down twin-stick bullet-hell, Godot 4.7, server-authoritative dedicated server with client-side prediction. Clients send input only; the server resolves every hit for both players and enemies (no PvP). - SimWorld: whole simulation as plain RefCounted objects (no nodes, no physics server), ~0.24ms/tick at peak load -- runs headless for free and drives 78 tests in under a second - BulletPool: struct-of-arrays bullet storage, replicated as spawn/despawn events rather than per-tick state - Emitter framework (Ring/AimedSpread/WallGap/ArcSweep) shared by trash enemies and bosses -- a new boss is data in src/content/content.gd, no simulation changes - The Warden of the Fold: stationary 4-phase boss built entirely on that format - Lobby hub with a portal into on-demand dungeon instances; one process hosts the hub plus every concurrent dungeon - Emergency escape: 3s server-owned channel, cancelled by damage - tools/check.sh, test.sh (GUT), smoke.sh (real server + bot clients over ENet), bench.gd; git hooks wired to the same scripts - docs/ARCHITECTURE.md, NETCODE.md, WORKFLOW.md, ROADMAP.md |
