What shipped today Two major themes: analyzing vanilla Stellaris for what makes events fun, then implementing the findings. Both v1.5 and v2 milestones closed by end of session.

The session started with the vanilla events analysis. 166 event files from the Stellaris game install were copied to the repo and analyzed programmatically. The data revealed a stark gap: vanilla events heavily use planet-visible effects (add_deposit: 852 uses), entity creation (create_ship: 614), technology grants (give_technology: 248, add_research_option: 280), and leader traits (add_trait: 676) — while Phantasmagoria only used invisible research lump sums and timed modifiers. The analysis was posted to #168 with categorized effect rules, Clausewitz syntax for each type, and a clear recommendation: keep the two-phase architecture but expand the roller’s effect vocabulary. This grounded the design decisions in data rather than guessing.

The implementation sprint that followed closed out the entire “make events fun” decomposition. Four new effect types landed: add_deposit for placing permanent resource deposits on surveyed planets (#181, with a new SCOPE_FROM: prefix convention for planet-scoped effects), give_technology for instant tech unlocks with curated early/mid tier lists (#182), and add_research_option for revealing new techs (#182). The roller was simplified by removing 4 non-working patterns (#188), keeping only tradeoff_trio and risk_spectrum — the only two that create meaningful player tension. Dig site pacing was fixed so middle chapters auto-resolve with a single effect while first and last chapters retain full player choices (#189).

The v2 situation work also completed. The YAML contract was documented in WORKING_MOD_CONTRACT.md with a new creeping_protocol.yaml fixture (#176). Situation rendering was confirmed already working (#177 closed as already done). Situation-specific validation was added to the source linter (#178). The remaining situation generation gate (#179) was moved to backlog since the generator redesign (#168) takes priority over expanding to new content types.

Completed

• #176 Define the v2 situation YAML contract
• #177 Enable situation rendering — closed (already working)
• #178 Add situation-specific validation to source linter
• #180 Add flat resource grants — closed (already implemented)
• #181 Add planet deposits (add_deposit) to anomaly effect vocabulary
• #182 Add give_technology and add_research_option to effect vocabulary
• #188 Remove non-working roller patterns
• #189 Auto-resolve middle dig site chapters
• #135 Define v2 support contract for situations — decomposed and all children shipped
• #168 Redesign generator for fun outcomes — decomposed and all children shipped
• #183 Remove non-working patterns and fix dig site pacing — decomposed and all children shipped

Release progress

• v1.5: 11/11 closed — complete
• v2: 5/5 closed — complete

Carry-over

• Run a fresh playtest with all the new effect types, pattern cleanup, and dig site pacing changes. This is the validation that the “make events fun” work actually improved the player experience.
• The vanilla events/ and common/ directories are in the repo root but not git-tracked. They’re reference data for analysis, not project code. Consider adding to .gitignore or moving to a reference/ directory.

Risks

• The new effect types (add_deposit, give_technology, add_research_option) have correct Clausewitz syntax per the vanilla analysis but haven’t been playtested in a generated release yet. There may be scoping issues, especially with add_deposit’s planet targeting via the SCOPE_FROM: prefix.
• The roller still doesn’t use the new effect blocks — they’re defined but not wired into the pattern structures (tradeoff_trio, risk_spectrum). A follow-up is needed to integrate deposits, tech grants, and research options into the rolling patterns so they actually appear in generated events.

Flags and watch-outs

• Both milestones are now fully closed. Need to decide whether to create a new milestone for the next playtest cycle or close the milestones entirely.
• The SCOPE_FROM: prefix convention in the renderer is a new pattern — any future planet-scoped effects should use the same convention.
• data/releases/playtest_fixed/ was cleaned up in a previous session; allocator.json was reset.
• The stale # DISABLED comments in scripts/phmg/generators/events.py (situation rendering) should be cleaned up.

Next session

1. Wire the new effect blocks (deposit, tech_give, tech_research_option) into the tradeoff_trio and risk_spectrum pattern structures so they actually appear in generated events
2. Generate a fresh playtest release with the new effects and pacing
3. Validate the full pipeline: generate → validate → render → lint → load in Stellaris
4. Playtest: do events feel more visible and choices more meaningful?
5. If the playtest passes, close out v1.5 and v2 milestones and plan the next release cycle
6. Consider creating a new milestone for the next feature batch
