Erik 0f1660d6ea feat(chat): CT-B1 — bound the transcript by retail's character budget
Campaign CT slice B1.

CORRECTION TO THE PLAN: this slice was written as "the transcript grows for the
life of the session — a slow leak". That was wrong, and the plan said it
because I read the retail-side finding and inferred our side without checking.
ChatLog has always been bounded (ConcurrentQueue, maxEntries default 500, with
a dequeue loop in Append). There was no leak.

The real gap is the UNIT. Retail bounds the rendered transcript by CHARACTERS —
0x2710, beheaded toward 0x1D4C at a newline boundary — while we bounded the
model by messages. Two different things: a window of 500 messages is far more
scrollback than 10,000 characters, and the message cap is a safety limit on the
log rather than a display rule.

So the budget is applied where retail applies it: on the rendered window, not
the model. ChatLog's entry cap stays as the model-level bound.

Two deliberate simplifications, both registered as CT-1 rather than left
implicit:

  - ONE threshold, not retail's two. The hysteresis exists to stop retail
    re-trimming an accumulating buffer on every append; we rebuild the visible
    list each time, so there is nothing to damp, and a second threshold would
    only make the oldest visible line jump around as messages arrive.
  - Whole-line cutting rather than a newline search near an offset — our unit
    already IS the line, which is what retail's newline preference is for.

Filtered-out lines deliberately do not consume budget: a line this window
filters out is not in retail's buffer at all, so counting it would mean turning
a filter OFF silently shortened the visible history.

Solution builds clean; full hermetic gate green.

acdream documentation map

This page is the entry point for project documentation. It distinguishes current sources of truth from implementation history so an old plan or issue banner cannot silently override the current program state.

Current snapshot — 2026-07-27

  • Milestone state: M3, “Cast a spell,” landed 2026-07-21. M4, “Live in the world,” is active.
  • M4 gameplay program: resume the pre-M4 world-interaction completion program. Favorite-spell overflow, status Use/Assess, and the complete assessment surface are user-accepted. Equipped-child picking and vendor browse/transactions remain Slices 46.
  • Structural/runtime state: all eight GameWindow decomposition slices, Modern Runtime Slices AJ, and the connected visual/lifecycle gates are complete. GameWindow is a 1,622-line composition/callback shell. AcDream.Runtime.GameRuntime owns canonical session, entity/object, gameplay, movement, physics, projectile, environment, and portal state; graphical and no-window hosts borrow the same owner graph.
  • Headless state: Slice K is complete. AcDream.Headless is a presentation-free Windows/Linux host with deterministic commands/events, shared immutable content, multi-session isolation, reconnect, resource telemetry, and 1/5/10/30-session gates. The final two-account native-Linux soak completed ten minutes, logged out through ACE, and converged every ownership ledger.
  • Linux graphical state: Slice L0 and the L1 implementation checkpoint are complete at 66f114b2 and 11501d52. Native Windows passes the active modern-GL/audio/window smoke. WSLg X11/Wayland correctly reject their missing GL_ARB_bindless_texture. Physical-Linux validation and L2L6 are explicitly deferred; resume at the supported AMD/NVIDIA L1 gate.
  • Completed gameplay gates: R6 locomotion/collision/projectile/teleport/ radar, two-client portal-out/materialization, indoor prepared collision, loot ordering, local/remote ground drops, and selection-marker lifetime.
  • Separate visual verification: issue #225, the shared-alpha lifestone/particle result; its connected resource-lifetime and performance routes pass.
  • Carried behaviour debt: issue #153 (far teleport onto an unstreamed edge), #116 (narrowed slide response), #235 (capped/RDP jump cadence), and the active temporary-stopgap rows in the divergence register.
  • Divergence audit: 189 active rows — IA 18, AD 38, AP 91, TS 38, and UN 4 — plus retained struck/retired historical rows such as TS-37.
  • Latest automated baseline: the Release build succeeds with the 17 test-project warnings tracked by issue #228; 8,826 tests pass and five are intentionally skipped. App passes 3,763 / 3 skips. The L1 Windows supported smoke and WSLg X11/Wayland negative-capability reports all end with zero window/GL/input/audio ownership.

Sources of truth

Read these in this order when deciding what to do next:

  1. plans/2026-05-12-milestones.md — the active playable outcome, freeze boundaries, and visual gates.
  2. plans/2026-04-11-roadmap.md — strategic phase ledger: shipped, active, deferred, and future work.
  3. ISSUES.md — tactical defects and small follow-ups. The status inside an issue is authoritative; physical order is not.
  4. architecture/retail-divergence-register.md — every known place runtime behavior can differ from retail.
  5. architecture/acdream-architecture.md and architecture/code-structure.md — ownership, dependency, update-thread, and extraction rules.
  6. architecture/worldbuilder-inventory.md — rendering/DAT code already owned in-tree versus mechanisms still ours to port.

If these disagree, milestones control the current outcome, the roadmap controls work ordering, the issue status controls the individual defect, and the architecture documents control implementation shape. Reconcile the stale document in the same change; do not leave both claims standing.

Research and implementation records

  • research/named-retail/ is the primary retail oracle: named pseudo-C, headers, symbols, and types from the Sept 2013 build.
  • research/decompiled/ is the older Ghidra fallback.
  • research/ contains focused pseudocode, traces, fixtures, and gate reports. A dated research note records evidence; it does not become a new roadmap.
  • superpowers/specs/ and superpowers/plans/ are per-slice design and execution records. Completed plans remain historical.
  • ci-and-releases.md is the SSOT for the Gitea CI pipeline, the self-hosted runners, and how alpha releases are published. Load-sensitive tests live in Lane=Timing; see release-gate.md before adding to it.
  • audit/ contains completion and conformance audits.
  • reference/ace-commands.md preserves the local ACE server's complete in-game command catalog and points to the authoritative per-command help surface.

Durable memory

  • ../claude-memory/MEMORY.md indexes the live subsystem memories and the render/physics digests. Read a domain digest before changing that subsystem, especially its DO-NOT-RETRY table.
  • ../memory/ contains stable engineering references such as the modern rendering pipeline, two-tier streaming, and toolchain notes.

Memory accelerates recall; it does not outrank the canonical documents above. When current truth changes, update the relevant canonical document and distill only the durable lesson into memory.

Historical and deprecated documents

  • bugs.md is the April 2026 bug snapshot. It is preserved for archaeology and is not an active ledger.
  • Dated plans and specs describe the decision at that time. Their completion wording is historical unless the current milestone/roadmap explicitly links the item as active.
  • Old R1→R8 architecture sequencing is superseded. Current execution comes from the milestones and strategic roadmap.

Documentation maintenance rules

  • Update milestone, roadmap, issue, divergence, architecture, and memory claims in the same commit when a shipped change affects them.
  • Keep one issue ID per defect. Narrow an issue in place; do not reuse another issue's number as a shorthand.
  • Mark automated, connected, and visual gates separately. An automated pass is not a visual acceptance, and an RDP throughput sample is not a local-display visual comparison.
  • Preserve research history, but remove stale “current/next” claims from living documents once the state advances.
