fix(rl): wire TrailTighten/TrailLoosen + SP20 P1+P5 foundation
scripts/audit-wiring.sh dogfood pass flagged a7 (TrailTighten) and
a8 (TrailLoosen) as actions with no consumer anywhere in the
codebase (canonical pearl_dead_trail_stop_actions_a7_a8). Fix
bundles SP20 P1 (per-unit trade state buffers) and P5 (trail-stop
kernels) since they're the same architectural work.
Three new kernels:
rl_unit_state_update.cu — per-batch trade state machine. Runs
AFTER fill+extract_realized_pnl_delta.
Detects open/close/reverse position
transitions and populates unit slot 0
with entry_price, entry_step, lots,
initial_r, trail_distance. Slots 1-3
allocated for SP20 P7 pyramid expansion
but unused this commit.
rl_trail_mutate.cu — handles a7/a8 actions. Mutates ALL
active units' trail_distance bounded
by ISV [MIN, MAX] with symmetric
reciprocal adjust rate per SP20 §4.12:
a7: trail = max(MIN, trail × rate)
a8: trail = min(MAX, trail / rate)
rl_trail_stop_check.cu — per-batch per-unit breach check. Reads
shared lobsim best book (bid/ask),
computes mid, compares to each active
unit's (entry ± trail). On breach,
OVERRIDE actions[b] to FlatFromLong
(a3) or FlatFromShort (a4). Force-close
routes through existing flat plumbing
per pearl_stop_checks_run_at_deadline_cadence.
SP20 v3 §3 P5 calls for routing close
via partial-flat (a9/a10) so only the
at-risk unit closes — that needs P4
(N_ACTIONS=11). For now, ANY unit's
breach closes ENTIRE position via full
FlatFromLong/Short.
Per-batch per-unit buffers (8 new in trainer):
unit_entry_price_d [B × 4] f32
unit_entry_step_d [B × 4] i32
unit_lots_d [B × 4] i32
unit_initial_r_d [B × 4] f32
unit_trail_distance_d[B × 4] f32
unit_active_d [B × 4] u8
pyramid_units_count_d[B] i32
unit_prev_pos_lots_d [B] i32 (state-machine tracker, separate
from extract_realized_pnl_delta's
prev_position_lots_d for clean
kernel composability)
4 new ISV slots (494-497):
RL_TRAIL_MIN_INDEX — trail distance floor (seed 0.001)
RL_TRAIL_MAX_INDEX — trail distance ceiling (seed 100.0)
RL_TRAIL_K_INIT_INDEX — initial trail multiplier (seed 2.0, Turtle 2N)
RL_TRAIL_ADJUST_RATE_INDEX — tighten ratio (seed 0.9; symmetric reciprocal for loosen)
RL_SLOTS_END: 494 → 498.
LobSim exposes bid_px_d() + ask_px_d() public accessors. RlLobBackend
trait extended with the two accessors; the LobSimCuda impl wires
through.
Override stack ordering per SP20 §2.3:
1. rl_pi_action_kernel (sample)
2. rl_trail_mutate (a7/a8 → mutate, before stop check)
3. rl_trail_stop_check (per-unit breach → override action)
4. actions_to_market_targets (execute, including overridden flat)
5. step_fill_from_market_targets
6. extract_realized_pnl_delta
7. rl_unit_state_update (detect post-fill transitions)
Audit infrastructure refined as part of dogfooding:
* audit-isv allowlist extended for BOOK_LEVELS (structural book
depth) and ACTION_* prefix (enum-mirror constants — these are
structural API contracts matching src/rl/common.rs::Action positions)
* audit-wiring action-handler regex now matches BOTH literal
`action == <idx>` and `action == ACTION_<UPPER_SNAKE>` patterns,
and treats != as a handler too (a guard against the action is
valid wiring)
Both `audit-isv.sh` and `audit-wiring.sh` PASS cleanly with the
full manifest. audit-diag scheduled for first SP20 phase that adds
diag fields (this commit deliberately keeps diag exposure minimal
— full per-unit + trail diag blocks come with SP20 P13).

docs(sp20): trader-grade trade management spec + audit infrastructure
Adds SP20 — full production trader-management system in one
greenfield commit (3-4 weeks of implementation work to follow):
* Tier 0: multi-resolution time-scaled market features (3 horizons)
* Tier 1: trade-arc awareness (4 features per batch)
* Tier 2: per-unit trail-stop (entry + trail + stop per unit)
* Tier 3: pyramiding + partial profit-taking (HalfFlat actions,
N_ACTIONS=9→11)
* Tier 4: Forward-Return-Distribution head + confidence gate +
per-batch anti-martingale sizing + position heat cap +
vol-adjusted defaults
Spec went through critical-review pass (v1→v2→v3):
* v1: 3 tiers, side-channel features, single-gate acceptance
* v2: 5 tiers added partial-flat + anti-mart + multi-res + checklist
* v3: foundational fixes for 4 CRIT + 6 SIG + 6 MIN findings
(per-unit pyramid state, encoder-input injection vs side-channel,
FRD head replaces survivor-biased checklist, override stack
ordering, per-batch anti-mart, real-time multi-res scales,
P-1 ceiling falsification gate, multi-tier acceptance)
§0 Foundational Principles (NEW, non-negotiable):
* §0.1 every numerical constant ISV-resident (no hardcoded #defines
in new kernels; structural-dim exception only)
* §0.2 every kernel/slot/head/action fully wired in same commit
* §0.3 diagnostics baked in at birth (every observable in JSONL)
* §0.4 per-phase ship-gate: all three audits must pass
Audit infrastructure shipped with the spec:
* scripts/audit-isv.sh — greps new .cu for hardcoded #defines
* scripts/audit-wiring.sh — verifies kernels/slots/heads/actions
have producer + consumer in code
* scripts/audit-diag.sh — runs local 100-step smoke, validates
manifest-listed jq paths present in JSONL
* scripts/audit-manifest/ — per-phase append manifests (kernels,
slots, heads, actions, diag-fields)
Naming discipline: audit scripts and manifest are SP-agnostic (no
`sp20-` prefix) per new pearl `feedback_no_sp_or_version_prefixes_in_file_names`
— they'll serve future SPs too. SP numbers belong only in
docs/superpowers/{specs,plans}/ filenames.
Audit scripts dogfooded — already caught two real violations on
existing code that the formal review missed:
* audit-isv: KL_EMA_ALPHA=0.05f hardcoded in rl_q_pi_distill_grad.cu
* audit-wiring: TrailTighten action (a7) has no handler in any
kernel (per pearl_dead_trail_stop_actions_a7_a8)
These violations are SP20 P5/P10 fix targets.
User decision recorded in spec §3 P-1: ceiling-falsification phase
intentionally skipped — SP20 is the architectural launchpad for
the broader trader system regardless of whether current arch could
be pushed further at 1M steps. P-1 may be revisited as standalone
work after SP20 ships.
