Coderain v0.2.0: The Architect

The story plans ahead now, the multi brain pipeline got a lot leaner, and a narrative game finally tracks its own world. This release also folds in a large robustness, security, and accessibility pass from the pre launch sweep.

Headline: the story plans ahead

• A rolling chapter outline (the book plan). It plots a few chapters ahead and writes a fresh one each time a chapter's goal lands, so the arc keeps a shape instead of wandering. It is not another per turn brain: it plans only at the memory fold cadence, so it costs almost nothing per turn.
• A new Plan panel. View the chapters, edit an upcoming chapter's goal to steer the arc, insert, reorder, delete, mark the current chapter done, or regenerate the whole plan. A new setting controls how many chapters to keep ahead (default 4).

Leaner brains, lower token cost

• The Director now plans on a slim context instead of the full writing payload, and skips the chain of thought it does not need. A big cut with no loss of function.
• A one click Cost vs quality control (Economy, Balanced, Quality). Economy is one model call per turn.
• Response length now actually caps output, and the confusing token settings are relabeled. The auto context budget is capped so a huge context model stops dumping its whole window into every call.
• Memory now records the causal chain (what, when, why, and the consequence) for important events only, so the long tail of memory stays cheap.

A narrative game tracks its world

• The world sidecar works with RPG turned off, so a plain story can move the clock, change location, set flags, and reveal secrets on its own.
• The location you move to links to your Locations, so that place's details stay in play as you move around.

Playing and authoring

• Create your own player character at the start of a story, or play as any character in the world.
• Tags and card to card links are now bubbles with autocomplete, and character traits work as tags.
• Creating a world also stocks the reusable Pieces library.
• A control for whether the AI may speak and act as your character (off by default).
• A fixed rule so characters only know what they actually witnessed.

Fixes and hardening

• Stop now truly halts a turn and no longer corrupts the transcript on disk.
• A pre launch sweep fixed five silent data corruption paths, added validate before apply, atomic config writes, and closed lock gaps.
• Security: cross origin mutating requests are refused, and uploads and zip archives are capped against zip bombs.
• A full accessibility pass (keyboard, screen readers, reduced motion, mobile viewport).

Getting it

• Download Coderain-win-x64.zip below for the zero setup Windows app, or run from source (see the README).
• Your existing stories are compatible, and unedited rule files upgrade themselves.

What's new since v0.1.0

• Bundled default world — "The Veil": a Matrix-inspired original (simulated reality, a machine war, waking up), set during the post-war truce. Fresh installs now open straight into an authored, playable world with quick actions, an author's-note tone, and output-regex cleanups — a live showcase of the memory system (pinned lore, chance encounters, delayed reveals, a hidden twist).
• SillyTavern feature parity, Tiers 1–4: character-card import, swipes, in-place edit, impersonate; lorebook depth (chance/group/delay/sticky/cooldown/AND-NOT triggers/semantic/recurse); macros, author's note, reply prefix, samplers, connection profiles; quick actions + persistent output-regex.
• Hardening (six multi-agent bug sweeps): concurrency locks so editing a world can't clobber a live turn's state, malformed-input guards, safer atomic writes on Windows, and a ReDoS guard on user regex.
