+# Effect String Syntax
+
+This document covers how effect strings work across the three card tables (citizens, domains, monsters), where the syntax currently diverges, and the proposed unified grammar.
+
+---
+
+## Current state by table
+
+### Citizens — `special_payout_on_turn` / `special_payout_off_turn`
+
+| Card | String | Meaning |

+
+---
+
+## Where the syntax diverges
+
+### 1. Resource notation — two forms
+
+Citizens and monsters use positional shorthand; domain KV pairs use colon notation:
+
+```
+# positional (citizens, monsters)
+choose g 2 m 2
+count owned_worker g 2
+
+# colon inside KV values (domain passives)
+action.end manipulate_resources mode=pay_to_player gain=v:1 pay=g:1
+manipulate_resources mode=self_convert pay=g:3 gain=v:3
+roll.set_one_die cost=g:2
+```
+
+### 2. `count` — same structure, different second word
+
+The two count patterns are syntactically parallel but semantically distinct. No unification needed beyond being aware they share a parser.
+
+```
+count owned_worker g 2     # count by citizen role owned
+count area Hills g 1        # count by monster area slain
+```
+
+### 3. `choose` — brackets sometimes, not always
+
+The bracket vs no-bracket distinction does carry real meaning and is worth keeping:
+
+```
+choose g 1 m 1                              # pick one of these resource amounts
+choose g 3 <citizens where name==Knight>    # pick a resource amount OR an entity
+choose <citizens where gold_cost<=2>        # pick an entity from a filtered set
+```
+
+### 4. `exchange` — only exists in citizens
+
+No equivalent pattern in domains or monsters. Could be expressed as a compound but `exchange` is readable:
+
+```
+exchange s 1 g 2    # pay 1s, receive 2g
+```
+
+### 5. `.` is doing three different jobs
+
+```
+harvest.gain_per_owned_citizen_name ...   # dot = phase separator (phase.verb)
+roll.set_one_die ...                       # dot = phase separator (phase.verb)
+action.end manipulate_resources ...       # dot = phase separator, then space, then verb
+action.modify_monster_strength +3        # dot = namespace separator, not timing
+effect.add action.emeraldstronghold      # dot = verb separator, then dot = namespace
+```
+
+### 6. `manipulate_resources` wrapper verbosity
+
+The `mode=` value is doing the same work as a first-word verb. The wrapper adds noise:
+
+```
+# current
+action.end manipulate_resources mode=pay_to_player gain=v:1 pay=g:1 optional=true
+
+# without the wrapper — same information
+action.end pay_to_player g 1 v 1 optional
+```
+
+---
+
+## Proposed unified grammar
+
+### Core rules
+
+1. **`.` means phase prefix only.** The left side is always a timing trigger (`harvest`, `roll`, `action.end`). Bare verbs have no dot.
+2. **Resource amounts are always positional: `g N`.** Colon notation (`g:N`) only appears inside `=` assignments in KV strings where a space would be ambiguous.
+3. **`choose` uses brackets for entity picks, bare words for resource picks.** Mixed is allowed: `choose g 3 <citizens where name==Knight>`.
+4. **Compound effects use ` + `.** Each leg is a self-contained effect: `m 4 + concurrent_flip_one_citizen`.
+
+### Proposed rewrites
+
+**Domain activation:**
+
+```
+# before → after
+action.modify_monster_strength +3                             → modify_monster_strength 3
+m 4 + concurrent_flip_one_citizen                             → no change
+manipulate_resources mode=self_convert pay=g:3 gain=v:3 ...  → self_convert g 3 v 3 optional
+choose <citizens where role==shadow>                          → no change
+s 3 + choose <citizens where role==soldier and gold_cost<=2>  → no change
+```
+
+**Domain passive:**
+
+```
+# before → after
+action.end manipulate_resources mode=pay_to_player gain=v:1 pay=g:1 optional=true  → action.end pay_to_player g 1 v 1 optional
+action.end manipulate_resources mode=take_from_player take=g:1 optional=true        → action.end take_from_player g 1 optional
+action.end manipulate_resources mode=pay_to_player gain=v:1 pay=m:1 optional=true  → action.end pay_to_player m 1 v 1 optional
+action.end manipulate_resources mode=take_from_player take=m:1 optional=true        → action.end take_from_player m 1 optional
+
+harvest.gain_per_owned_citizen_name Knight g 1   → no change
+roll.set_one_die target=6 cost=g:2               → no change
+effect.add action.emeraldstronghold              → no change
+```
+
+**Citizens and monsters:** no changes needed — syntax is already consistent within each table and the proposed rules codify what they already do.
+
+---
+
+## What stays as parsed strings vs opaque keys
+
+All effects in the tables above are **parsed strings** — a new card with different numbers works without any code change.
+
+The only candidates for opaque keys are effects with branching prompt logic unique to a single card that cannot be generalized with different parameters:
+
+- `concurrent_flip_one_citizen` (Cursed Cavern) — multi-player concurrent event
+- `modify_monster_strength 3` (Ancient Tomb) — board-state mutation prompt
+
+Even these stay as strings under the unified grammar; they just dispatch to named functions rather than an inline parsing branch. The DB string is the key; the function is the implementation.
