The whole request
Deploy MarginaliaPages v0.10 (src/MarginaliaPages.sol) on Ethereum mainnet: ONE contract, constructor (address hook, address annex, address intake, bytes32 action, address signer) = (0xf0457dd0cf526686190e4f057ba19db14d34a0cc the live MarginaliaHook of launch 1283, 0xd0c0d97aebe9194606bcc46ce56524eee4615543 the live MarginaliaAnnex of launch 1384, 0x1397434cd35e8a9C8aC312A61D3A285EB31dea56 the IdentityMD Intake, bytes32('oracle.request@oracle-1') the oracle action, 0x5598Aa9146215Bc13eb26f2c692Ad1461Fd32982 the IdentityMD oracle signer) — the same oracle constants the live hook holds as INTAKE, ACTION and ORACLE_SIGNER.
This REPLACES the v0.9 Pages deployment of job 0925298b (old constants: 0.1 base, no cap, 90/5/5, no gate), which is not used.
What it is: the page market of Marginalia, notes in the margin of every trade. A page of a writer's marginalia is the seat in that writer's room: the site delivers the writer's sealed notes and reasoning to page holders first.
Pages are bought and sold against a CAPPED linear bonding curve priced in IMD 0xD34a99Bc0f67aE1bbd63C660e6d0b0dd03E263B7: page n costs min(BASE 0.05 IMD x n, CAP 10 IMD), so the line meets the cap at page CAP_PAGE 200 and every later page costs 10 IMD (priceOf sums the line segment and the flat tail; the curve reserve always covers every holder selling out at any depth).
Pages are never transferable (buy and sell on the curve only) and a wallet holds at most MAX_PER_WALLET 10 pages of one subject (TooManyPages).
BUY GATE (sell is never gated): eligible(wallet) is true when the wallet holds at least MARG_GATE 10,000 MARG (hook.token(), 0xfa0efea559bde229031c2b0a219472316647759c), OR has posted at least one note on the hook or the annex (the first two words of either contract's records(address) getter: score, posted), OR is on identity.md's settled WhitelistCurator at the fixed address WHITELIST 0xcB0b0531e86A9aC36Fa865cA8e3dbccF047FDA91 (contributedBy(address) > 0, read by staticcall, a failed read counts as not listed); otherwise buy reverts NotEligible.
Every trade pays FEE_BPS = 10% of its value: ISSUER_BPS 80% of the fee to the issuer in IMD, BURN_BPS 10% of the fee buys MARG on the launch pool through the hook's PoolManager (a quiet buy, no hook fee; unlockCallback accepts only the PoolManager) and sends it to 0x000000000000000000000000000000000000dEaD, the remaining 10% of the fee goes to the hook's pools through hook.fundPot.
An issuer is any address (subjectOf(address) pays itself) or an X handle nobody has claimed (subjectOfHandle(string), lower-cased and validated on chain: 1-15 of a-z 0-9 underscore): pages of a handle trade on the same curve while the issuer's 80% waits in escrow.
CLAIMS ARE ORACLE-ATTESTED, there is no attester of ours: the handle's owner posts a tweet naming their wallet; anyone calls requestClaim(handle, tweetId), paying the Intake's current price for action oracle.request@oracle-1 (refused above MAX_PRICE 1 IMD); the contract builds the question itself (questionBody: fetch X's public embed JSON https://cdn.syndication.twimg.com/tweet-result?id=&token=a, if user.screen_name is the handle answer the single address in text, else zero; answerType address, evidence panel, head 1, panelSize 5, quorum 4, guards.sources the syndication prefix, consumer = this contract) and buys one answer through the Intake with callback onOracleResult.
The callback accepts only the Intake, verifies the EIP-712 attestation against the signer (OracleAttestationConsumer, domain IdentityMD Oracle v2), requires chainId == block.chainid, agreed >= quorum >= 4 and panelSize >= 5, consumes the request id once, and: a real address becomes the payee, takes the escrow less the oracle price reimbursed to whoever asked (if the escrow covers it), and is paid directly from then on; the zero address is a failed claim, retriable at once, costing only the asker.
One request in flight per subject; an unanswered one may be abandoned by anyone after ANSWER_DEADLINE 3 days (a late delivery is then refused). One successful claim per subject ever. Escrow unclaimed CLAIM_WINDOW = 90 days after the first buy is recycled into the hook's pools by anyone, never while a claim is pending.
No owner, no pause, no upgrade, no attester, nonReentrant trades, claims and callback. The constructor reads no chain state (the launcher rehearses constructors in an empty EVM); it stores the five values (annex may be zero: that gate leg is then off). Deploy from this repository as it is; adapt only what deployment strictly requires; keep every number.
Tests: forge test --match-path test/Pages.t.sol (14 tests against the local hook, a whitelist mock etched at the fixed address, an annex-records mock, a local Intake mock and an EOA signer, incl. the capped curve at 210 pages, the per-wallet limit, every gate leg and ungated selling, the 200k callback stipend and replay/tamper refusals).

The review is complete and
.imd-findings.jsonholds 8 entries. The working tree has no stray files (the findings file andtest/scratch/are git-ignored; nothing else changed).What I found in MarginaliaPages v0.10
- Medium, sell liveness. Every trade runs a MARG burn swap on the launch pool as a hard precondition. When that pool sells out of MARG or its LPs withdraw,
sellreverts even though the contract holds the full curve reserve, so holders cannot leave. Buys freeze too. A self-contained proof undertest/scratch/PagesSellLiveness.t.solfails on the current code for exactly this reason in both scenarios. - Medium, permanent wrong payee. The claim question asks for any address written in any tweet by the handle, with no claim intent required. Anyone can submit such a tweet, the answered address becomes the payee forever, takes the escrow, and the real owner's claim reverts AlreadyClaimed.
- Low. The 90-day recycle window runs from the first buy only, so escrow deposited seconds earlier is swept. Arbitrary bytes32 subjects accept buys whose escrow nobody can claim. A pending claim can be griefed, and abandon plus recycle in one transaction can take a late legitimate claimant's escrow.
- Info. Callback uses about 146k of the 200k stipend in the worst local case. Intake v1 gives no failure callback. A scope entry lists what was read and what could not be reached.
Verified sound: curve arithmetic and reserve invariant, fee split, per-wallet cap, every buy gate leg, PoolManager-only and Intake-only callbacks, replay and tamper refusals, reentrancy coverage. Nothing launch-forbidden is present: no delegatecall, selfdestruct, proxy, owner or post-deploy initialization, and the runtime is under the EIP-170 limit.
Not reached: the live mainnet bytecode of IMD, the Intake, the WhitelistCurator, the Annex and the oracle signer, since no RPC was available, and the Router, Annex, Pricer and Treasury sources beyond the parts Pages depends on.

mediumA handle is bound forever to whatever address any of its tweets ever contained; anyone can trigger it and the real owner is locked outsrc/MarginaliaPages.sol:391
recycle() sweeps escrow deposited seconds earlier, because the 90-day window is measured from the first buy onlysrc/MarginaliaPages.sol:419
escrowSince is set once, at the first escrowed fee (line 289), and never advanced by later deposits. 90 days after a single tiny first buy, anyone may call recycle(subject) and the entire escrow, including the issuer's share of trades made moments before, goes to the hook's pools.
A handle whose room only became active late loses its accrued share to the pools even though no reasonable claim window elapsed for that income, and since recycle is permissionless a bot can do it in the same block as a large buy. This matches the brief's wording ('90 days after the first buy'), so it is reported as a design hazard rather than a deviation; the adapter may want escrowSince to track the latest deposit, or to recycle only escrow older than the window.
alice buys 1 page of subjectOfHandle('fresh') at t0 (escrow 0.004 IMD, escrowSince = t0).
At t0 + 90 days bob buys 10 pages (escrow becomes 0.264 IMD).
In the same block anyone calls recycle(subject).
Expected (by intent): only escrow that waited 90 days unclaimed is recycled.
Actual: all 0.264 IMD is sent to hook.fundPot; escrow is 0 (test/scratch/Probe.t.sol::testRecycleSweepsFreshEscrow logs 'escrow before 264000000000000000 after 0').
buy() accepts any bytes32 as a subject; escrow of non-address, non-handle ids (including bytes32(0)) can never be claimedsrc/MarginaliaPages.sol:248
buy/sell take a raw bytes32 subject and never check that it is an address id (top 96 bits zero, non-zero) or the hash of a normalised handle. For any other id payeeOf returns zero (line 193), so 80% of every fee is escrowed under an id that requestClaim can never target (it only derives ids from a validated handle), and the escrow can only be recycled to the pools after 90 days.
A buyer who mis-derives the id (an un-normalised handle hashed off chain, a hash of '@handle', a different prefix, or bytes32(0)) buys pages of a room that no one will ever own, with no revert; the curve reserve is still returnable by selling, but the fee share is unrecoverable by the intended issuer.
Suggested fix: refuse ids that are neither an address id nor registered by a prior subjectOfHandle-derived buy (e.g. a
known[subject]flag set by abuyHandle(string)entry point), or at least reject bytes32(0).alice (eligible) calls buy(keccak256('not a handle'), 10, max).
Expected: revert, the id is not a subject.
Actual: succeeds; subjects[id].escrow = 0.44 IMD, payeeOf(id) = 0, requestClaim cannot reach it, only recycle after 90 days.
Same with buy(bytes32(0), 1, max): escrow 0.004 IMD, payee zero (test/scratch/Probe.t.sol::testArbitrarySubjectEscrowUnclaimable).
A pending claim is a public, 0.5 IMD per round lock on the subject; after ANSWER_DEADLINE anyone may abandon and immediately recycle before the owner retriessrc/MarginaliaPages.sol:346
Only one request per subject may be in flight and anyone may open it. A griefer who front-runs the handle owner's requestClaim with a bogus tweet id makes the owner's transaction revert ClaimPending; while the panel has not answered (minutes normally, up to 3 days if the body is refused or the panel splits, since Intake v1 delivers no failure callback) the subject is locked.
The cost is the oracle price per round, and the griefer's own price is not reimbursed on a zero answer, so it is bounded, but combined with recycle() it has a loss path: when escrowSince + 90 days has passed and a legitimate claim is pending but late, anyone can call abandonClaim(subject) at requestedAt + 3 days and recycle(subject) in the same transaction, sending the escrow to the pools before the owner can re-request; a late but valid answer is then refused (UnknownRequest) and the owner's 0.5 IMD is lost as well.
onOracleResult uses ~146k of the 200k callback stipend in the worst local case; an ERC-1271 signer or a heavier IMD transfer narrows the marginsrc/MarginaliaPages.sol:397
The callback verifies the signature and performs up to two IMD transfers plus six storage writes. Measured under the test fixture with an EOA signer and an OpenZeppelin ERC20 as IMD, a claimant with zero IMD balance and a fresh zero-balance payee: 145,927 gas of the 200,000 the Intake grants.
If the live oracle signer is a contract (SignatureChecker falls back to an isValidSignature staticcall after the ECDSA attempt), or the live IMD token's transfer costs more than a plain ERC20, the headroom shrinks; a callback that runs out of gas is recorded as undelivered and not retried, the 0.5 IMD price is lost and the subject is locked for 3 days, and every retry fails the same way, so the handle could never be claimed.
The reference's guidance is to only verify and store in the callback and pay in a later call of the user's own.
test/scratch/Probe.t.sol::testCallbackGas: 20 pages of 'gasy' bought, asker with 0 IMD after paying, payee a fresh address; intake.deliver with gas 200_000 logs 'ok true gas used 145927'. Replace the EOA signer with an ERC-1271 contract and the mock IMD with a token whose transfer costs ~30k more and the same delivery fails inside the stipend.
Claims are pinned to Intake v1 request() with no failure callback, so refused bodies or split panels silently cost the price and lock the subject for 3 dayssrc/MarginaliaPages.sol:352
The brief pins the IdentityMD Intake version 1 (0x1397...) and the plain request(). The oracle-consumer reference says version 2 is the one to use for anything new and offers requestWithFailure so the consumer learns of a refused body (status 1) or a panel that did not agree (status 2). With v1 such outcomes never reach the contract: the asker's 0.5 IMD is spent, claims[subject] stays set, and the subject cannot be asked about again until abandonClaim after ANSWER_DEADLINE.
The body also contains the keys head, guards.sources and consumer whose acceptance by the v1 schema the auditor could not verify offline (the live Judge uses head and guards.allow and is answered, so they are likely accepted). This is spec-conformant and reported for the adapter and the panel; no code change is required by the brief.
requestClaim('h', id) where the panel splits: no callback arrives.
Expected (with v2 failure hook): the contract clears the claim at once.
Actual: claims['h'] remains set, requestClaim reverts ClaimPending for 3 days, then anyone must call abandonClaim; the price is gone either way.

I found one defect in the Pages economics, with a reproduction. It's recorded in
.imd-findings.jsonwith 53 coverage rows. I changed no files; the scratch tests I used to confirm it are deleted.Finding 1 (medium): one 10,000 MARG balance makes any number of wallets eligible, so the 10-pages-per-wallet limit doesn't hold (
src/MarginaliaPages.sol:241)- Cause:
eligible()only checks the wallet's MARG balance at the moment it buys. MARG can be transferred freely, so the same 10,000 MARG can pass the gate for one wallet after another, even inside a single transaction. - Cost: on mainnet
hook.margPriceInImd()reads about 2.97e13, so the whole 10,000 MARG costs about 0.3 IMD. After that, each extra wallet costs only gas. That breaks the contract's own promise that "no wallet can corner a room" and that every room "costs a sybil something per wallet". - Reproduction (run with forge on the local test setup): a writer uses 20 throwaway wallets and one MARG stash to buy pages 1–200 of their own room, costing about 1,025 IMD after their own 80% fee share comes back. Six real readers then buy pages 201–260 at the 10 IMD cap, paying 660 IMD. The writer sells all 200 pages and makes +506.13 IMD. The readers can now get back only 82.35 IMD for their 60 pages.
- Fix: this is a design call for the author. Options are to lock or escrow 10,000 MARG per wallet while it holds pages, or to drop the MARG route and keep the whitelist and posted-a-note routes.
What holds:
- Curve reserve: it always equals the cost of buying every page from zero to the current supply, so the reserve covers every holder selling out at any depth, including past the cap.
- IMD accounting: the contract's IMD always covers reserves plus unclaimed writer shares plus any MARG burns waiting for retry.
- Fee split: each fee divides exactly 80/10/10.
- Selling: it is never gated.
- Claim flow: the oracle callback, escrow refund to the asker, recycling and abandonment all behave as specified.
- Live mainnet dependencies: the hook and annex
records, the whitelistcontributedBy, andhook.token(),hook.imd()andhook.poolManager()all answered as expected. The Intake price is 0.5 IMD, under the 1 IMD limit. The oracle signer has no code, so it's a plain wallet key. - Callback gas: the worst case for a successful claim (a payee and an asker who both start with zero IMD) used about 180k gas in the local mock, measured including the mock's own call overhead. That's under the 200k limit but close, so it's worth watching. A real IMD transfer to a new address costs about the same as the mock token (about 52.8k gas estimated).
What I looked at and left out:
- Unprotected MARG burn: each trade's burn and
burn()buy MARG with no minimum output. A sandwich attack isn't profitable: each trade burns at most 1 IMD, and the attacker pays about 5.5% in pool and hook fees on their own trades. - Blocking the owner's claim: an attacker can jump ahead of the handle owner's claim request at 0.5 IMD a try, but the owner can avoid that by sending through a private mempool.
Coverage: all 9 Pages entry points are traced. So are the hook functions Pages relies on:
fundPot,unlockCallback, and the no-fee MARG buy path throughbeforeSwap/afterSwap. All other hook, annex, router, judge and treasury entry points are markedunreached, since they are outside this area.The working tree has untracked files I didn't create: shell dotfiles,

Audit flowAgent #281found 2 info
The review is complete and
.imd-findings.jsonholds the result: two informational findings, no critical, high or medium defects, and a coverage row for every listed entry point.What I audited. The control flow of MarginaliaPages v0.10 against the Execution Trace, Periphery and First Principles guides: every state-changing entry point traced from its checks through state writes, external calls and failure paths, plus the hook paths Pages depends on (fundPot, unlockCallback, the quiet-buy branches of beforeSwap and afterSwap) and the OracleAttestation periphery.
What held.
- Accounting. The curve reserve equals the sum of page prices at every supply, the price formula never rounds, and the contract's IMD balance stays equal to reserve plus escrow plus pendingBurn on every buy, sell, claim, recycle and burn path.
- Claims. Only the Intake can deliver, only an open request of Pages' own is accepted, the oracle UUID is consumed once, chain, panel and quorum are checked, abandoned requests refuse late answers, and recycle never runs over a pending claim.
- Callback budget. I measured the delivery with cold state (fresh balances, cold slots, separate transaction) at about 146k gas, under the 200k stipend. The question body stays at 1013 characters and the claim prefix at 116 with the longest possible inputs, inside the Intake's limits.
- Periphery. The OracleAttestation library is byte-identical to the canonical copy in the oracle-consumer reference. The consumer differs only in using the memory variant of the signature check, with the same semantics.
- Burn path. The try/catch around the burn swap cannot be exploited by gas starvation, partial fills roll back cleanly, and
burncan only spend pendingBurn.
What I reported, both informational.
- The signer, Intake and action are pinned with no rotation path. The brief asked for this, but the oracle-consumer reference says consumers must be able to repoint them. If the key rotates or Intake v1 stops being served, every handle claim fails and all handle escrow recycles into the pools after 90 days.
- Buying pages of an address subject that is a contract unable to move IMD, including Pages itself, strands the issuer share inside the contract outside all accounting. Only the buyer's own fee is lost.
What I could not verify. Whether Intake v1 accepts the body keys
head,guards.sourcesandconsumerfor a scalar address answer cannot be checked offline. The live Judge and Annex use the same key shapes, and the brief prescribes them, so this is recorded as an unreached lead. No launch.json exists in the tree yet, so the manifest row is also marked unreached.

An address subject needs no registration and pays itself. When the address is the Pages contract itself,
_distributeFeedoesIERC20(imd).safeTransfer(address(this), toIssuer): a no-op transfer that leaves the IMD in the contract but tracked by nothing (not reserveOf, not escrow, not pendingBurn), so the accounting invariant the tests assert (imd.balanceOf(pages) == sum(reserve) + sum(escrow) + pendingBurn) no longer holds and the IMD can never leave.The same share is lost for good when the subject is any contract with no way to move IMD (the hook, the PoolManager, 0x...dEaD). Only the buyer loses (their own fee), there is no victim besides the dust, so this is informational: a one-line refusal (subject == address(this), or payeeOf returning zero for this contract so the share goes to escrow/recycle) closes it.

The review is complete and the findings file is written. The working tree is clean apart from
.imd-findings.json, which git ignores.Outcome. No critical, high or medium defect found in MarginaliaPages v0.10 within the Access Control, Trust Gap and Asymmetry guides. Four findings are recorded, two low and two informational, each with a concrete state and call sequence. All 52 listed entry points plus two invariants have coverage rows, none unreached.
Findings written to
.imd-findings.json:- Low, buy gate at line 241. The MARG leg of
eligible()is a balance snapshot and MARG is transferable, so one 10,000 MARG bag passes the gate for unlimited fresh wallets in one transaction. One actor held 100 pages of one subject in my reproduction, with the bag returned afterwards. This contradicts the natspec promise that no wallet can corner a room. On mainnet today 10,000 MARG is worth roughly 0.3 IMD. - Low, escrow clock at line 314.
escrowSinceis reset only byrecycle(), never by accrual after the window. Two handles with identical trades end up with one handle's new fees instantly sweepable and the other's protected for 90 more days, depending only on whether a stranger calledrecycle()at day 90. - Info, claim path immutability. Intake v1, the action id and the signer are immutable with no owner. If the Intake price goes to zero or above 1 IMD, the Intake stops completing, or the signer rotates, handles can never be claimed and all escrow drains to the pools after 90 days.
- Info, callback gas. The success path of

Live mainnet reads confirmed the hook getters, annex records, whitelist, Intake price of 0.5 IMD and an EOA signer all match what the constructor pins.Not reached. The already-live hook, annex, router, judge and treasury were not re-audited beyond the paths Pages calls; their rows say so.

No other path can ever set subjects[handle].payee, so after 90 days from the first buy recycle(handle) moves the issuer's whole share to the pools.

The review is complete. The findings file holds zero defects and 55 coverage rows, and the working tree is otherwise unchanged.
Result: no math defect found in MarginaliaPages. The areas I covered in depth:
- Curve arithmetic. I fuzzed
priceOfagainst a per-page reference sum of min(0.05·n, 10) and checked additivity, so the reserve always equals the exact sell-out value at any depth, including the cap edge at pages 199, 200 and 201. The closed-form division by 2 is exact because the product is always even. - Fee split. Every single-page price gives a fee of exactly one tenth, and the 80/10/10 legs reconcile to the fee with no truncation. The smallest fee is 0.005 IMD, so no leg ever rounds to zero.
- Casts and bounds. The uint64 supply cast is guarded by the per-wallet limit, the burn swap's exact-input check compares the delta word for word, and MARG output at the live price stays far inside int128.
- Balance invariant. Contract IMD equals reserves plus escrow plus deferred burns through buys, sells, deferred and retried burns. A buy from inside a foreign PoolManager unlock reverts entirely, so a v4 flash-taken MARG balance cannot pass the gate.
- Live wiring. Over public RPC I confirmed the hook's token, IMD, poolManager and pool key getters, both records getters, the whitelist contract's
contributedBy, 18 decimals on IMD and MARG, and an Intake price of 0.5 IMD. The pinned-block fork suite could not run on public RPC, so I ran a scratch copy at the latest block: the live-IMD oracle callback fits the 200k stipend and a real trade against the live hook passes.
One lead I quantified and dropped. The automatic burn swap uses a zero minimum output. A sandwich on a thinned pool left the victim's burn deferred rather than lost and cost the attacker about 180 IMD in fees, with gain capped at the burn tranche, so it is not a defect.
Not reached. Entry points of the Router, Judge, Treasury and Annex are outside this launch and untouched by the Pages math. They are recorded as holding on that basis, not from an independent trace.

Review complete. The findings file is written at the repository root and every one of the 50 listed entry points has a coverage row.
What I did
- Reproduced every specialist finding against the code with scratch tests under
test/scratch/(all demonstrate the behaviour on the current code) and merged duplicates: the MARG-gate sybil finding reported by two areas became one finding, and the three oracle-pinning notes became one. - Ran the full Pages suite (63 tests green), then rehearsed Pages on a mainnet fork at the latest block through the public node: the live hook, live launch pool, live IMD and live Intake price all behave as the contract expects, and the claim callback used about 148k gas, under the 200k stipend.
- Read the live hook, annex, whitelist, Intake and signer on chain to confirm every ABI Pages depends on exists and matches the constructor arguments.
- Did my own pass over the contract, the deployment model and the manifest. No new defects surfaced. Size, constructor purity, argument order and the schema of
launch.jsonall check out.
Findings kept (4)
- Low. The MARG leg of the buy gate reads a transferable balance, so one 10,000 MARG bag qualifies unlimited wallets in a single transaction. The per-wallet cap bounds a wallet, not an actor, and the natspec's "costs a sybil something per wallet" does not hold for this leg. Recalibrated from the economics specialist's medium: no funds go to a wrong party, the brief specifies a balance gate, and the same cornering is possible through the notes leg for about 0.1 IMD per wallet.
- Low. The escrow clock is one-sided. It starts only when zero and is reset only by
recycle, so identical handles get different protection depending on whether a stranger recycled. - Low. Buying pages of the Pages contract's own address, or of a sink like the hook or the dead address, strands the 80% issuer share as untracked IMD.
- Info. Handle claims are pinned to Intake v1, one action, one signer and the 200k stipend with no rotation path. Not a defect, since the brief asks for exactly this, but a liveness assumption the README should state.
Coverage
The 9 Pages entry points plus the hook, token and treasury functions Pages actually exercises are traced as holds or finding. The 32 entry points of the already-live hook, annex, router and judge that this launch neither deploys nor calls are recorded as unreached, with only their ABI surface verified on mainnet.
Nothing blocks deployment. The three low findings are the author's call on design, not fixes required for safety.

From audit_flow. An address subject pays itself without a claim. When the subject is the Pages contract itself, _distributeFee's
IERC20(imd).safeTransfer(payee, toIssuer)moves IMD from Pages to Pages: the share stays in the contract but is tracked by nothing (not reserveOf, not escrow, not pendingBurn) and can never leave, so the accounting identity the test suite asserts (balance == sum reserve + sum escrow + pendingBurn) no longer holds.The same share is lost for good when the subject is a contract with no way to move IMD (the hook, which only holds IMD as PoolManager claims; the PoolManager; 0xdEaD). Only the buyer loses their own fee share, so low. A one-line refusal of subject == address(this) (and optionally of known sinks), or routing such shares to escrow so recycle() can move them, closes it.
