feat(scenario): rob-cash-depletion-recovery — recover from sudden cash drain (financial turnaround / SC2 anchor)

Wave-6 Group J robustness seed. Frames a mid-episode cash-crisis
recovery: agent starts with a normal operating economy (fact + powr +
proc + 1 harv + 2 mines + a small 3tnk defender squad) and an
indivisible 1400 reserve (= exactly one proc rebuild). A scripted
`hunt` 4tnk strike destroys the refinery mid-episode; the agent must
`build('proc') + place_building` and re-issue `harvest` to restart
income before the EV bar 2500 / deadline 6300 bites.

Tiers — one new controlled variable per level:
• easy — LIGHT strike (1× 4tnk + 2 own 3tnk). Defenders intercept
the lone 4tnk; proc SURVIVES. Discriminator: stall = 0
income → bar unmet → LOSS.
• medium — PROC DESTROYED mid-game (2× 4tnk + 3 own 3tnk; proc dies
~tick 453). Agent must rebuild proc with the indivisible
reserve and resume harvest. No-rebuild fails the
`building_count_gte:proc:1` clause permanently.
• hard — PROC + TENT BOTH DESTROYED (4× 4tnk + tent placed in the
attack lane; tent dies tick 183, proc tick 273). Same
1400 reserve = one rebuild; the tent rebuild is OPTIONAL
(not in the win predicate). Tests prioritising the
income-restoring proc rebuild over the defensive-tech
tent rebuild.

Hard registered NOT_APPLICABLE in test_hard_tier.py because enemy
actors don't honour spawn_point (CLAUDE.md oramap.rs footgun) so
foreign-latitude `hunt` 4tnks drift to the active spawn and over-
pressure the tuned defender ring, destroying the fact and collapsing
the recovery test into a fact-defence test. Spawn variation would
compete with the recovery-discipline signal for attribution; the
within-tier discriminator (strike severity → rebuild decision
discipline) stays clean instead.

Real-world anchors: financial cash-crisis recovery / SC2 cash-drain
rebuild / DR after critical-infra loss / bankruptcy turnaround under
deadline.

Tests: 52 scripted no-cheat assertions cover stall / no-rebuild /
build-army / intended-rebuild × 3 levels × 4 seeds + structural and
determinism checks.

+#
+# Real-world anchor: financial cash-crisis recovery after a sudden

+#
+# Pack frame: the agent inherits a NORMAL operating economy (fact +
+# proc + 1 harv + 2 mines + a small 3tnk defender squad), with
+# starting_cash = 1400 — exactly enough to rebuild ONE refinery (proc
+# cost 1400). A scripted enemy `hunt` strike (2-3× 4tnk) charges the
+# refinery early in the episode (medium: proc destroyed ~tick 543;
+# hard: proc + tent both destroyed by ~tick 453). The agent must:
+#   1. notice the proc died (no income, harv has no place to refine),
+#   2. `build('proc')` and `place_building` it adjacent to the fact
+#      with the indivisible reserve cash,
+#   3. re-issue `harvest` to the surviving harv (the death event
+#      interrupts the harvest loop), so income resumes and the EV
+#      bar (2500) is met before the deadline.
+#
+# Difficulty axis (one new controlled variable per tier):
+#   • easy   — LIGHT strike (1× 4tnk + 2 own defenders). The defenders
+#              intercept the lone 4tnk before the proc dies; the agent
+#              never has to rebuild. The bare skill is "commit to
+#              harvest, don't stall, EV bar gets met". `has_building:
+#              proc` is satisfied trivially by the surviving original.
+#   • medium — PROC DESTROYED mid-game (2× 4tnk + 1 own defender;
+#              proc dies ~tick 543 ≈ "~tick 600" target). Agent must
+#              rebuild proc with the 1400 reserve AND redirect harv
+#              back to the patch. Stalling, ignoring the death, or
+#              spending the reserve on army units all LOSE.
+#   • hard   — PROC + TENT BOTH DESTROYED (3× 4tnk + tent placed in
+#              the attack lane at (13,18); proc dies ~tick 453, tent
+#              dies ~tick 273-453). Agent must rebuild proc (1400);
+#              losing the tent removes the infantry production queue
+#              (an army-rebuild detour is even more unaffordable).
+#              + 2 seed-driven spawn_point groups (NORTH y=14 / SOUTH
+#              y=26) so the strike geometry flips per seed.
+#
+# Why this pack is different from `econ-recover-from-zero-cash`:
+#   • `econ-recover-from-zero-cash` starts from a MINIMUM VIABLE KIT
+#     with $0 cash and no aggression — the test is the SCALING
+#     recovery (harvest first, save 2000, build weap, build a 2nd /
+#     3rd harv). The recovery is INTERNAL (no enemy event).
+#   • `rob-cash-depletion-recovery` starts from a WORKING ECONOMY
+#     with $1400 cash and ENEMY AGGRESSION that destroys the refinery
+#     mid-episode. The test is the EXOGENOUS-EVENT recovery (notice
+#     the strike, replace the dead refinery, restart income). The
+#     agent never needs to scale past 1 harv; the test is rebuilding
+#     the income channel that was destroyed, not extending it.
+#
+# Why this pack is different from `econ-replace-dead-harvester`:
+#   • `econ-replace-dead-harvester` kills a HARVESTER (a unit) with a
+#     raider 4tnk that targets workers specifically; agent replaces
+#     the dead worker with `build('harv')`.
+#   • `rob-cash-depletion-recovery` kills a REFINERY (a building) with
+#     a `hunt` 4tnk that targets the nearest combat actor (defenders
+#     and proc are MustBeDestroyed and engaged); the agent rebuilds
+#     the dead BUILDING with `build('proc') + place_building`. The
+#     recovery is a building-production task, not a unit-production
+#     task — one chain step deeper (build + place + adjacency).
+#
+# Why this pack is different from `mid-economy-under-fire`:
+#   • `mid-economy-under-fire` is an ongoing-attack defense: the
+#     raider drives at the harvesters and the agent must keep the
+#     harvest loop running THROUGH the attack. Throughput is
+#     sustained; no rebuild is needed.
+#   • `rob-cash-depletion-recovery` is a one-shot strike followed by
+#     a rebuild: the strike LANDS (the proc dies), throughput STOPS,
+#     and the agent must rebuild the destroyed infrastructure to
+#     restart income. The decision is replan-after-loss, not
+#     defend-and-sustain.
+#
+# ENGINE FACTS verified (CLAUDE.md + /tmp/probe_*.py 2026-05-19/20
+# against the installed openra_train wheel):
+#  1. `hunt` ScriptedBehavior (openra-sim/src/scripted_bot.rs lines
+#     151-166 / 242-253) collects FOES including Building actors and
+#     each unit attacks the nearest. With 4tnk attackers placed in
+#     melee range of the proc, the proc becomes the closest enemy
+#     and is engaged on turn 1.
+#  2. Proc strike timing (probe-measured, all attackers at x=14
+#     adjacent to proc at x=12):
+#     - easy:  1× 4tnk + 1 own 3tnk @ x=18 → defender kills 4tnk
+#       first; proc SURVIVES the full episode (verified to tick 6303).
+#       Discriminator: stall yields 0 income; intended harvest WINS.
+#     - medium: 2× 4tnk + 3 own 3tnk @ x=18 → proc dies tick 453
+#       (≈ "~tick 600" target); 4tnks then die to the defender ring
+#       so fact and powr SURVIVE → rebuild is feasible.
+#     - hard: 4× 4tnk + tent at (13,*) + 5 own 3tnk → tent dies tick
+#       183, proc tick 273; 4tnks die to the defender ring shortly
+#       after; fact and powr SURVIVE to ~tick 6300 (probe H3).
+#     The defender-vs-attacker ratio (medium: 90 vs 80 dps; hard:
+#     150 vs 160 dps) is tuned so the attackers BARELY land the
+#     building kill and then die — preventing the 4tnks from chain-
+#     killing fact after the proc falls (which would convert the
+#     run to a LOSS via `not building_count_gte:fact` regardless of
+#     the rebuild).
+#  3. Proc cost = 1400 (verified econ-startup-from-scratch.yaml line
+#     135). starting_cash = 1400 funds exactly ONE proc rebuild; any
+#     pre-spend (powr 300 / tent 500 / e1 100) starves the rebuild.
+#  4. After proc dies, the surviving harv's harvest loop is
+#     interrupted (the engine cannot deliver ore without a refinery).
+#     Once the rebuild completes and the new proc lands, the agent
+#     must re-issue `harvest(harv_id, mine_x, mine_y)` for the harv
+#     to deliver into the NEW proc — the harvest auto-cycle does not
+#     auto-resume across a destroy-rebuild gap.
+#  5. Tick alignment (CLAUDE.md): max_turns 70 → ceiling 93 + 90·69 =
+#     6303 > 6300 ✓. within_ticks 6300; fail after_ticks 6301
+#     (deadline bites as a reachable LOSS, not a draw).
+#  6. Persistent unarmed enemy `fact` marker far east at (120,20)
+#     prevents engine auto-`done` via the all-enemies-eliminated
+#     path (CLAUDE.md auto-done footgun) — once the strike force is
+#     killed, the marker keeps the episode running so the EV bar
+#     can be reached and the deadline can bite as a LOSS.
+#  7. Hard tier is registered NOT_APPLICABLE in test_hard_tier.py
+#     (the UPGRADED spawn-variation contract). Reason: the
+#     controlled variable for hard is the STRIKE SEVERITY (proc +
+#     tent destroyed vs medium's proc only). The enemy-bot footgun
+#     (CLAUDE.md: enemy actors don't honour spawn_point) makes a
+#     clean per-spawn enemy partition geometrically infeasible —
+#     foreign-latitude 4tnks always place and drift to the active
+#     base, over-pressuring the tuned defender ring and destroying
+#     the fact (converting the recovery test into a fact-defence
+#     test). Spawn variation here would compete with the recovery-
+#     discipline signal for attribution.

+  capability: reasoning
+  real_world_meaning: >
+    Financial recovery after a sudden cash drain caused by an
+    emergency outflow that destroys the operation's income channel.
+    The agent inherits a normal operating economy with just enough
+    reserve cash for ONE refinery rebuild; an exogenous strike
+    destroys the refinery mid-episode; income halts. The agent must
+    notice the loss, commit the indivisible reserve to rebuilding the
+    refinery, and redirect the harvester back to the patch — fast
+    enough that the revenue bar is still cleared before the deadline.
+    Stalling, ignoring the destruction, or spending the reserve on
+    army units all miss the bar.
+  robotics_analogue: >
+    Post-disaster operations restart after the critical processing
+    node is destroyed by an external event mid-mission. The
+    autonomous operator has one collector still alive, no working
+    capital beyond a single processing-node rebuild allowance, and a
+    deadline. Recovery requires identifying the lost asset,
+    committing the reserve to rebuilding it (not to defenders or
+    expansion), and re-tasking the collector back to the source once
+    the new node is operational.

+      attack the refinery AND a barracks ('tent') is placed in the
+      attack lane and is also destroyed early in the episode (tent
+      down by around tick 180, refinery by around tick 270). Your
+      reserve is still $1400 — exactly one refinery. To recover:
+      queue another Refinery (`build` "proc"), place it adjacent to
+      the fact, and re-issue `harvest` to the surviving harv. The
+      tent rebuild is OPTIONAL (it isn't part of the win predicate);
+      prioritise the income-restoring proc rebuild even though more
+      buildings are gone. Win = economy_value ≥ 2500 AND you own a
+      'proc' AND a 'fact', before tick 6300. Stalling, ignoring the
+      rebuild, attempting to rebuild the tent first (no cash left
+      for the proc), or spending the reserve on army units all miss

+"""No-cheat + solvency proof for `rob-cash-depletion-recovery` (Group J
+robustness — mid-episode recovery after a scripted enemy strike
+destroys the refinery and halts income).
+
+The pack frames a CASH-CRISIS RECOVERY decision: the agent inherits a
+normal operating economy (fact + proc + 1 harv + 2 mines + a small
+defender squad) with $1400 cash — exactly enough to rebuild ONE
+refinery (proc cost 1400). An enemy `hunt` 4tnk strike destroys the
+proc mid-episode (medium ≈ tick 540; hard ≈ tick 450; on easy the
+defenders intercept the lone 4tnk and the proc survives). The agent
+must `build('proc') + place_building` and re-issue `harvest`.
+
+For every level + every hard seed (1-4):
+  * INTENDED chain (notice the destruction, build proc, place, re-
+    issue harvest) WINS;
+  * STALL (only `observe`) LOSES every tier — no harvest income, EV
+    stays at the starting $1400, bar (2500) unmet, clock bites;
+  * NO-REBUILD (harvest with the starting harv but never `build`
+    proc) is the EASY FLOOR (wins easy where the proc survives) but
+    LOSES medium/hard (the structural `has_building:proc` clause
+    fails after the proc is destroyed);
+  * BUILD-ARMY (spend the 1400 reserve on powr → tent → e1 instead
+    of replacing the proc) LOSES medium/hard — the reserve is
+    starved, the proc rebuild never completes, the bar is unmet.
