title: GE Flipping (margin trading)
domain: economy

status: verified
version: 6 # 6: bounce-fix 7 2026-08-29 (governor comment 10471) — 'closed' is no longer a sink: after a completed sell's proceeds are collected and the ledger is reconciled + ARCHIVED, the physical GE slot is released to free via the explicit archival transition `closed -> free` (a deliberately closed cancelled sell releases the same way), and the committed two-rotation regression proves one slot completes buy/collect/sell/collect, archives the first ledger, and opens a SECOND buy in the same slot without losing, duplicating, or mutating the archived record. Previous (v5, bounce-fix 6): the 4h buy-limit reset NEVER cancels an offer (offer lifetime = independent quote_age_policy: stale edge or strategy reallocation only); explicit buy-filled-awaiting-collect / sell-filled-awaiting-collect states so completed offers must pass through the GE collection box (ge_collect) before reuse or closing; SIDE-AWARE per-slot ledgers (buy: quoted units = filled + still_open + cancelled_unfilled, acquired items = filled ONLY, cash = spent + still_committed + refunded; sell: quoted = sold + still_open + returned_unsold) with committed negative fixtures for phantom refunded buy units, a full buy sold before collection, and a full sell closed before proceeds collection. Capped/floored tax model + its 4 selftest fixtures and the asynchronous scheduler behavior preserved (owner decisions 2026-08-28).

summary: >-
Buy-and-sell Grand Exchange margin flipping: place resting buy offers at
the low edge of an item's price band and resting sell offers at the high
edge, harvesting the spread on high-volume items. There are no skill or
quest requirements — capital breadth and slot discipline are the whole
game. Members accounts run 8 GE slots over the full candidate set; F2P
accounts get 3 slots and F2P-tradeable rows only (separate F2P path in
profit_drivers). Model (governor 10323 + 10390, 2026-08-28): every GE
slot is an INDEPENDENT asynchronous sub-state machine (free / buy-open /
buy-filled-awaiting-collect / buy-cancelled-awaiting-collect /
ready-to-sell / sell-open / sell-filled-awaiting-collect /
sell-cancelled-awaiting-collect / ready-to-requote / closed) driven by a
global scheduler pass that acts only on dispatchable slots and never
closes or advances unrelated ones; completed offers (full buys and full
sells) land in the GE COLLECTION BOX and must pass through ge_collect +
ledger reconciliation before assets are reused or the slot closes;
'closed' is NOT a sink — the physical GE slot is released to free via
the archival transition `closed -> free` after the completed cycle's
ledger is reconciled + archived, so every slot runs flip after flip
through rotations and breaks (two-rotation reuse regression); the
4h buy-limit ledger (limit_used / first_fill_ts / limit_resets_at /
remaining) is DISTINCT from offer expiry — a limit-window reset NEVER
cancels an offer and cancellation NEVER renews the limit; ge_cancel
moves filled items, refunded CASH, unsold units and proceeds to the box,
and every snapshot satisfies SIDE-AWARE per-slot conservation (buy:
quoted units == filled + still_open + cancelled_unfilled with acquired
items == filled only, cash == spent + still_committed + refunded; sell:
quoted == sold + still_open + returned_unsold);
economy.ceiling_gp_per_hour is the TYPED economic ceiling and
gp_per_hour_low/high are documented realized scenario bounds. Pinned
worked example + committed validator fixtures prove the model.
accounts:
membership: hybrid # members: 8 slots/full set; F2P: 3 slots/F2P rows (see economy)
min_level: 3 # post-Tutorial Island baseline; no skill requirement
requires_quest: []
requires_other:
- "Post-Tutorial Island account with Grand Exchange access (no skill or quest requirement)"
- "Members account: 8 GE slots, full candidate set (the modeled path below). F2P account: 3 GE slots and F2P-tradeable rows only — run the F2P path in profit_drivers."
- "Minimum starting capital: per slot = buy edge x 4h limit (arrowtips 2.23M, iron bar 1.45M, cosmic 2.196M, silver ore 0.949M, swordfish 3.09M, lobster 1.59M, magic logs 9.264M, mud 1.728M at the 2026-08-27 snapshot) — full 8-slot members coverage ~22.5M; the 3-slot F2P path needs ~5.5M (iron 1.45M + cosmic 2.196M + silver 0.949M). Capital below one slot's requirement takes that slot off the table."
best_practice:
equipment:
- item: cash stack (flip capital)
why: "Gross margin per item is a few gp, so profit scales with quantity and the 4h
buy-limit window caps per-item volume — capital breadth (more candidates/slots
covered) matters more than any gear. Bulk flipping at scale needs ~20M+ cash."
source: "OSRS wiki — Merchanting (Bulk quantity flipping)"
techniques:
- name: flip the spread, not the trend
why: "Flipping profit is the buy/sell spread between pending offers (the impatience
premium), NOT price movement; it is safer when the item has high trade volume."
source: "OSRS wiki — Merchanting (Flipping)"
- name: prefer dynamic-price items, avoid static-price items
why: "Static-price items have no spread to harvest; only dynamic-price items carry
an exploitable margin."
source: "OSRS wiki — Merchanting (flipping guidance: 'strongly recommended to not
flip static-price items')"
- name: quote at the band edges, never instant-buy/sell
why: "Instant matching pays the standing offer's price (the market's impatience
price); a resting offer fills when a matching offer appears at or better than your
price. The 2% convenience fee makes sub-2%-spread staples unprofitable at band
edges outright, so the edges are where the margin lives."
source: "OSRS wiki — Merchanting (How the Grand Exchange works); OSRS wiki — Grand Exchange
(2% tax since 2025-05-29, capped 5M/item)"
- name: pace quotes inside the 4h buy-limit window, watch connected limits
why: "The buying rate is restricted to a set quantity every 4 hours per player, and
some items share a connected limit with related items — treat those as one bucket
when filling slots. The window starts when the FIRST unit of the window is bought
(first_fill_ts) and resets 4h later. The reset ONLY restores buying capacity —
it never cancels, expires, or otherwise affects a resting offer — and cancelling
an offer does NOT renew or restart the window."
source: "OSRS wiki — Grand Exchange (Buy limits; Grand Exchange/Buying limits)"
- name: run the path that matches the account's slot set
why: "Members get eight GE slots and may trade any row; F2P accounts get three slots
and may only purchase free-to-play rows. The modeled economics below assume the
members set — a hybrid account must swap to the 3-slot F2P path (Iron bar /
Cosmic rune / Silver ore) instead of chasing members-only rows it cannot buy."
source: "OSRS wiki — Grand Exchange (Members get eight Grand Exchange slots ... free players are limited to three. Additionally, free players may only purchase members' items)"
- name: treat each slot as its own asynchronous machine; the scheduler never touches resting slots
why: "A slot's offer fills on its own timeline (partial fills keep resting). The
global scheduler pass acts only on dispatchable slots (free -> quote,
*-awaiting-collect -> ge_collect, ready-to-sell -> sell, ready-to-requote ->
requote, closed -> free archival release) and leaves resting buy-open /
sell-open slots untouched — one slot's cancel or close never advances an
unrelated slot. A FULLY FILLED offer never sells or closes directly: it
first enters an explicit buy-/sell-filled-awaiting-collect state because
its assets sit in the GE collection box until ge_collect (finding 2,
governor 10390). A 'closed' slot is only ever transient: the completed
cycle's ledger is archived at close and the pass releases the physical
slot to free (closed -> free), so the same slot runs the next flip —
never one flip and done (governor 10471)."
source: "governor review comments 10323 + 10390 + 10471 (2026-08-28/29); OSRS wiki — Grand Exchange / Bank (collection box); docs/action-grammar.md"
- name: keep a per-slot offer ledger; ge_cancel -> collection box -> ge_collect -> reconcile, never strand units
why: "Every slot tracks its side-aware ledger: a BUY quote partitions units into
filled + still_open + cancelled_unfilled with acquired items = filled ONLY (the
unfilled/cancelled quantity is CASH: spent / still_committed / refunded), and a
SELL quote partitions sold + still_open + returned_unsold. ge_cancel moves
filled items, refunded CASH, unsold units and sale proceeds to the GE COLLECTION
BOX (never directly to inventory); a separate ge_collect withdraws them and the
ledger is reconciled before the slot is reused. The ONLY cancel triggers are a
stale scanned edge (margin no longer positive) or an explicit strategy
reallocation — never the 4h buy-limit reset, which merely restores capacity."

The ceiling 149,500 itself is an economic bound, never an achieved rate. Cancelling never renews the buy limit and the limit reset never cancels an offer (governor 10390 finding 1)."

scheduler_iteration: >-
One pass over every slot exactly once, at the 600 s quote-check cadence.
Only dispatchable slots act: free -> quote (ge_buy), buy-filled-
awaiting-collect / buy-cancelled-awaiting-collect /
sell-filled-awaiting-collect / sell-cancelled-awaiting-collect ->
ge_collect, ready-to-sell -> sell (ge_sell), ready-to-requote ->
requote, closed -> free (archival release: the completed cycle's
ledger was archived at close; the pass returns the physical slot to
free so the next flip can begin). Resting buy-open / sell-open slots
produce NO action and are never closed, advanced, re-quoted or touched
by the pass. A pass therefore advances only the slots whose sub-state
is dispatchable, a completed offer always passes through its
*-filled-awaiting-collect state (ge_collect) before its assets are
reused, and a closed slot is only ever transient — released to free
rather than left to strand after one flip (governor 10471).
quote_age_policy: >-
Offer lifetime is INDEPENDENT of the 4h buy-limit ledger. Resting
offers are re-checked at the 600 s cadence and kept resting while the
scanned margin stays positive — a profitable resting offer remains
open regardless of limit_resets_at (a limit-window reset only restores
buy capacity; it never cancels, expires, or implies cancelling an
offer). An offer is aborted ONLY on a stale band edge (scanned margin
no longer positive) or an explicit strategy reallocation (slot freed
for a better candidate / stop condition). No-fill alone never aborts an
offer whose edge still clears the margin.
persisted_state: >-
Per-slot record persisted between passes and across breaks: sub-state,
item, quoted qty, and SIDE-AWARE buckets — buy side: filled, still_open,
cancelled_unfilled, cash_quoted, spent, still_committed, refunded;
sell side: sold, still_open, returned_unsold, proceeds_in_box,
cash_collected; plus limit_used, first_fill_ts, limit_resets_at,
quote placed_at, last check_ts. The GE offers themselves persist
server-side; the record is the agent's copy of truth for the scheduler
and conservation checks.
limit_ledger: >-
Per item: limit_used (units bought so far in the current 4h window),
first_fill_ts (when the FIRST unit of the window was bought),
limit_resets_at = first_fill_ts + 4h, remaining = limit - limit_used.
The ledger controls ONLY the buying rate: it is DISTINCT from offer
expiry (offers rest independently of the window), cancelling never
renews or restarts it, and the reset never cancels an offer — a requote
before limit_resets_at may buy at most remaining (buy_capacity_ok:
limit_used + qty <= limit). A slot with limit_used == limit cannot
place a new or requoted buy until limit_resets_at; its resting offer
is unaffected.
conservation: >-
SIDE-AWARE per-slot invariants at every snapshot (governor 10390
finding 4). BUY side: quoted units == filled + still_open +
cancelled_unfilled per item, and ACQUIRED ITEMS == filled ONLY — the
unfilled/cancelled quantity is a CASH refund, never refunded units;
cash_quoted == spent + still_committed + refunded. SELL side: quoted
units == sold + still_open + returned_unsold per item (a partial sell
legitimately spans sold + still_open). No negative or duplicated
quantities; impossible pairs (still_open + cancelled_unfilled on a
buy; still_open + returned_unsold on a sell) are violations. Phase
gates: a buy-filled-awaiting-collect slot has NOTHING sold yet (a full
buy cannot sell before ge_collect) and a sell-filled-awaiting-collect
slot holds its proceeds in the box; a 'closed' slot has no uncollected
proceeds or cancelled/returned units — it holds ONLY the archived
(immutable) cycle record, and the physical slot is released to free
via the closed -> free archival transition so the SAME slot can run
the next flip (governor 10471; two-rotation reuse regression: the
archived rotation-1 ledger survives rotation 2 bit-for-bit).
Committed validator fixtures —
including the negative fixtures (phantom refunded buy units; a full
buy sold before collection; a full sell closed before proceeds
collection; a 'closed' sink that strands the slot after one flip) —
prove the invariants and the scheduler dispatch.
break_resume: >-
Breaks are taken only when no slot is dispatchable: every slot is
resting (buy-open / sell-open) or free — never mid-collect, mid-place,
or in an *-awaiting-collect state. A closed slot is only ever
transient (archived and released to free by the pass), so a break
never catches the activity between archive and release; full state
(offers server-side + the persisted per-slot record) survives the
pause; resume by re-opening the GE, re-checking offers, re-running the
scheduler pass and continuing each slot from its persisted sub-state.
Slots and slots only: the 8-slot members / 3-slot F2P activity is
never downgraded to single-slot work.

# ================= WORKED EXAMPLE (pinned, deterministic — owner addendum 2026-08-28; slot-machine walk per governor 10323, corrected per 10390) =================
# Members account, 8 GE slots, capital 22,500,000 gp. Snapshot prices 2026-08-27
# (buy/sell = low/high edge; tax = min(floor(0.02 x sell), 5,000,000)).
# The run below walks THREE slots in detail (arrowtips / iron / cosmic) exactly as
# the committed scheduler-dispatch + conservation fixtures; the other five slots
# behave identically to the iron slot and are omitted for brevity.
# Ledgers are SIDE-AWARE throughout: a BUY's acquired items are `filled` ONLY;
# unfilled/cancelled quantity is CASH (spent / still_committed / refunded).
#
# t0 idle -> scan -> schedule (pass 1): all slots free. Scheduler dispatch:
# free -> quote. Slot ledger after the pass (conservation holds):
# arrowtips: buy-open, quoted 10,000 @ 223; cash_quoted 2,230,000
# = spent 0 + still_committed 2,230,000 + refunded 0
# iron: buy-open, quoted 10,000 @ 145; cash_quoted 1,450,000
# cosmic: buy-open, quoted 18,000 @ 122; cash_quoted 2,196,000
# Unit buckets: quoted == still_open for every slot; filled/cancelled = 0.
#
# t1 wait, ~18 min: arrowtips PARTIAL fill 4,000/10,000 (a6 verdict PARTIAL).
# BUY ledger: quoted 10,000 == filled 4,000 + still_open 6,000 + cancelled 0.
# Acquired items = 4,000 ONLY; they sit in the GE collection box (collectible
# at any bank), while the offer keeps resting with 6,000 still open. Cash:
# cash_quoted 2,230,000 == spent 892,000 + still_committed 1,338,000.
# limit_ledger: first_fill_ts now, limit_used 4,000, limit_resets_at = +4h,
# remaining 6,000 (window CAPACITY — not an offer deadline).
# Iron: FULL fill 10,000/10,000 -> buy-filled-awaiting-collect (units sit in
# the box until ge_collect; the slot cannot sell them directly — finding 2).
# Iron cash: spent 1,450,000. Cosmic: no fill; offer keeps resting (edge
# positive, quote age within policy — finding 1: no-fill alone never aborts).
#
# t2 cadence -> schedule (pass 2): dispatch ONLY the dispatchable slot:
# iron buy-filled-awaiting-collect -> ge_collect (a9): withdraw 10,000 units;
# ledger reconciled (quoted 10,000 == filled 10,000; cash spent 1,450,000,
# no refund); sell edge positive -> ready-to-sell.
# arrowtips buy-open -> NO ACTION (resting, partial fill still open).
# cosmic buy-open -> NO ACTION (resting, no fill, edge positive).
# => the pass never closes or advances unrelated slots (regression fixture).
#
# t3 pass 3: iron ready-to-sell -> sell-open (a7): 10,000 @ 157 (high edge).
#
# t4 iron sell-open FULL fill -> sell-filled-awaiting-collect: proceeds
# 1,570,000 sit in the GE collection box until ge_collect. SELL ledger:
# quoted 10,000 == sold 10,000 + still_open 0 + returned_unsold 0.
#
# t5 pass 4: iron sell-filled-awaiting-collect -> ge_collect (a9): withdraw
# 1,570,000; tax floor(157 x 0.02) = 3/item -> net (157 - 3 - 145) x 10,000
# = 90,000. proceeds_in_box -> cash_collected; ledger reconciled and
# ARCHIVED (the immutable cycle record: quoted 10,000 == sold 10,000);
# sub-state -> closed, and the SAME pass's archival dispatch releases the
# physical slot: closed -> free (governor 10471). The slot can place the
# next flip's buy immediately — it is never stranded after one flip.
# Conservation: quoted 10,000 == sold 10,000, zero proceeds left uncollected.
#
# t6 LIMIT RESET, NOT AN OFFER EVENT (finding 1): arrowtips reaches
# limit_resets_at with 6,000 still open on the resting offer. The window
# reset restores buying capacity ONLY — the offer KEEPS RESTING at its edge;
# nothing is cancelled and the 4,000 filled units stay collectible in the
# box. Cosmic likewise unaffected.
#
# t7 arrowtips offer FULLY fills the remaining 6,000 -> buy-filled-awaiting-
# collect -> pass 5 ge_collect: withdraw 10,000 units (4,000 from the t1
# partial + 6,000 from the t7 fills — the units are what the offer actually
# bought; NO phantom "refunded units"). BUY ledger: quoted 10,000 == filled
# 10,000; cash 2,230,000 == spent 2,230,000 (still_committed 0 — a full fill
# spends its whole quote). Sell edge positive -> ready-to-sell.
# limit_ledger: window 1 used 4,000 (t1); window 2 (post-reset) used 6,000.
#
# t8 pass 6: arrowtips ready-to-sell -> sell-open 10,000 @ 244 -> full fill ->
# sell-filled-awaiting-collect -> pass 7 ge_collect: proceeds 2,440,000;
# tax floor(244 x 0.02) = 4/item -> net (244 - 4 - 223) x 10,000 = 170,000
# (matches the 170,000 4h/slot table row) -> closed (ledger archived) ->
# closed -> free: the arrowtips physical slot is released for the next flip.
#
# t8b SECOND ROTATION in the SAME physical slot (governor 10471 regression):
# the iron slot released at t5 and the arrowtips slot released at t8 are
# free and dispatchable again — pass 8 quotes a NEW arrowtips buy in the
# iron slot (free -> buy-open, a4; buy_capacity_ok re-checked against the
# CURRENT window's limit_ledger). Rotation 1's archived ledgers (iron
# closed record, arrowtips closed record) remain archived and bit-for-bit
# untouched — no loss, duplication, or mutation — while the live ledger is
# a fresh rotation-2 record (quoted 10,000, cash_quoted 2,230,000,
# still_open 10,000). This is the committed slot_reuse regression: a slot
# completes one flip, is released, and runs the next one.
#
# t9 STALE-EDGE recovery (cosmic, finding 1 cancel trigger): at a cadence check
# the cosmic LOW edge has risen 122 -> 126: net 128 - floor(128 x 0.02)=2 -
# 126 = 0 -> margin no longer positive -> quote_age_policy aborts the offer
# (ge_cancel, a8): ZERO units were filled, so the collection box receives
# refunded CASH 2,196,000 and NO items. BUY ledger: quoted 18,000 == filled 0
# + still_open 0 + cancelled_unfilled 18,000; cash 2,196,000 == spent 0 +
# still_committed 0 + refunded 2,196,000. Sub-state -> buy-cancelled-
# awaiting-collect. (The 18,000 never-purchased units are cash, never
# "refunded units" — the phantom-items fixture.)
#
# t10 pass 8: cosmic buy-cancelled-awaiting-collect -> ge_collect: withdraw
# refunded CASH 2,196,000; ledger reconciled (refunded -> collected). The
# fresh-edge margin is still 0, so the slot is NOT re-quoted: ready-to-
# requote requires a positive margin — decide free, capital reallocated to a
# candidate that still clears (e.g. magic logs); a requote in a later window
# is governed by buy_capacity_ok as usual (the cancel did NOT renew the
# window, and the next reset does not cancel anything).
#
# t11 FIRST SCHEDULED BREAK after 6-10 passes (midpoint 8): every slot is
# resting (buy-open / sell-open), free, or collected (closed) — nothing
# dispatchable; per-slot records persisted (slot_state_machine.break_resume);
# take-break 60-240 s (a10); RESUME at a2 (re-open GE) -> a6 (check-fills)
# -> schedule (next pass) -> continue per-slot from persisted sub-state.
# Breaks never strand an offer and never interrupt a collect/place.
#
# t12 STOP: session target (e.g. 900,000 net) -> collect -> complete; capital
# fell below floor -> idle -> complete; 3 consecutive failed passes -> failed.
#
# Rate qualification (typed ceiling vs realized scenarios — finding 5):
# ceiling 149,500 = 598,000 per 4h / 4h — ideal full fills of all 8 slots,
# zero overhead. Realized HIGH 138,000 = 149,500 x 37/40 (37 min resting waits
# + 3 min scan/place/collect per 40-min rotation at the 600 s cadence).
# Realized LOW 74,750 = 149,500 x 0.50 (requote-heavy: every 4h window's
# volume completes only after one ge_cancel + requote cycle — the no-fill
# remainder is refunded and re-quoted on the next window, halving volume).
# The ceiling is NEVER presented as an achieved runtime rate.

notes:
- "Flipping is standard gameplay; the detectable signal is quote churn — keep per-offer pacing humanised, never instant-buy/sell loops."
- "The 2% fee (since 2025-05-29) and 5M/item cap make sub-2%-spread staples unprofitable at band edges; re-scan before every rotation."
- "Thin/volatile items: a resting offer can sit for hours — offer lifetime is governed by quote_age_policy (abort only on a stale scanned edge or strategy reallocation), NEVER by the 4h buy-limit window. A limit reset merely restores buy capacity; it cancels nothing."
- "Partial fills are normal: filled units of a partial buy sit in the GE collection box (collectible at any bank) while the offer keeps resting; never cancel-and-replace a partially-filled offer mid-window just to churn — the side-aware ledger keeps the filled qty attached until the offer fully fills or is aborted per quote_age_policy."
- "ge_cancel NEVER returns items/coins directly to inventory: everything lands in the GE collection box. BUY cancels return filled items + refunded CASH (the unfilled quantity is cash, never 'refunded units'); SELL cancels return unsold units + proceeds received. Reuse a slot only after ge_collect + side-aware ledger reconciliation (conservation invariants)."
- "The 4h buy limit is independent of offer life: cancelling does not renew it and the reset does not cancel offers. A slot at limit_used == limit cannot place a new/requoted BUY until limit_resets_at (first_fill_ts + 4h); its resting offer is unaffected."
- "Breaks are safe only when no slot is dispatchable (resting offers or post-collect points, see a10 and break_resume); state = GE offers + the persisted per-slot record, which survive the pause."
- "A completed cycle NEVER strands a slot: after ge_collect the ledger is reconciled + archived at 'closed' and the scheduler pass releases the physical slot to free (closed -> free archival release), so every slot keeps running flip after flip. Never model a slot as one-flip-then-done (governor 10471)."

within 2% of the fastest declared fast-xp site's modelled
ores/hr x its ore xp.
- GE-margin entries (tags include flipping and/or merchanting —
the unambiguous margin signals): the 2% GE convenience fee is
rounded DOWN to whole coins per item and capped at 5,000,000 GP
per item, so net_per_cycle MUST equal
income - min(floor(0.02*income), 5_000_000) - cost.
Fractional-tax arithmetic (0.98*sell - buy) and uncapped tax
(6M on a 300M sale) are errors.
NOTE: the generic `ge` tag alone does NOT gate this rule — a
training/processing/procurement entry may legitimately carry
`ge` while its income/cost model has nothing to do with flip tax.
- GE-flip lifecycle (flipping/merchanting entries): the 4h buy-limit
ledger (limit_used / limit_resets_at) is DISTINCT from offer
expiry — a limit-window reset never cancels an offer and cancelling
never renews the limit; every slot is an independent asynchronous
sub-state machine (canonical set: free / buy-open /
buy-filled-awaiting-collect / buy-cancelled-awaiting-collect /
ready-to-sell / sell-open / sell-filled-awaiting-collect /
sell-cancelled-awaiting-collect / ready-to-requote / closed) driven
by a global scheduler pass that never touches unrelated slots;
ge_cancel moves filled items, refunded CASH, unsold units and
proceeds to the GE collection box for a separate ge_collect;
per-slot conservation is SIDE-AWARE (buy: quoted units =
filled + still_open + cancelled_unfilled and acquired items =
filled ONLY — the unfilled/cancelled quantity is cash, never
refunded units; sell: quoted = sold + still_open + returned_unsold)
with phase gates (a full buy cannot sell before collection, a full
sell cannot close before proceeds collection);
closed has ONE outgoing transition — the archival release
``closed -> free`` — so a completed cycle's physical GE slot
returns to free for the next flip instead of stranding forever
(governor 10471); the two-rotation reuse regression proves a slot
completes buy/collect/sell/collect, archives the first ledger, and
places a second buy in the same slot without loss, duplication, or
mutation of the archived record;
economy.ceiling_gp_per_hour is the TYPED economic ceiling and
0 <= gp_per_hour_low <= gp_per_hour_high <= ceiling.
- Regression fixtures (--selftest): a fractional-tax flipping
entry must FAIL; an above-cap high-value flip with the
