We need answer as legal advice. Need cover all points. Need be careful. Need maybe mention privilege? Not necessary. Need structure.

We have facts and governing law. We need advise. Need likely recommend postpone/decline under current terms because missing key protections/status. Need address current direct-use clause protects only no use in case-in-chief, no derivative-use bar, rebuttal broad, no cooperation credit, agency sharing, uncharged conduct exceptions. Need Omar status matters because if Omar is cooperating/charged, his statements could be contradicted? Need explain contradiction and derivative-use risk. Need request written protections: derivative-use restriction, narrower rebuttal clause, use immunity for proffer? But proffer not immunity; can request "statements may not be used to develop leads, witnesses, records, charges" and "no derivative use" or "Kastigar-like" but maybe government won't agree. Need request status info: (1) Omar status as target/subject/witness/cooperating/charged/plea, whether he has proffered; (2) whether government has evidence contradicting Lena's assertions; (3) subjects/topics/witnesses; (4) whether any known participants are targets/subjects/cooperating; (5) nonprivileged basis for "subject" designation; (6) if seeking "cooperation credit" what exact written promise/motion policy? Need maybe request written cooperation agreement or letter stating benefits, or at least no promises.

Need advise not contact Omar/co-defendants/potential witnesses to learn status; lawful channels only via counsel? Actually rule 8 says defendant should not contact co-defendant/potential witness; counsel must obtain through lawful channels. Need mention not to ask Omar, colleagues, company, friends? Need preserve records already done; no ongoing misconduct. Need perhaps "do not attempt to investigate through Fenn, former colleague, or witnesses." Need not "clean up" devices? Need preserve. Need maybe "do not delete or alter; already preserved." If no ongoing misconduct no need to proffer.

Need discuss proffer rules in general. Need be clear that no benefit guaranteed. "First person in gets deal" is not legal; credit only if written promise or later motion. Good-faith assistance may not get 5K1.1. Need maybe mention under supplied sentencing rules? The problem says "under the supplied sentencing rules" but not included; assume standard sentencing guidelines? Need mention cooperation credit can occur only under written agreement or government motion, e.g., USSG 5K1.1 or 18 U.S.C. 3553(e)? Need not overstate if not in facts. Need mention substantial assistance motion unavailable without govt motion except maybe safety-valve? But the rules state. Need maybe "There is no enforceable right to cooperation credit, and the draft contains no promise. The government's 'no promise' clause forecloses any contract claim. A later 5K motion is discretionary." Need mention if "Lena believes first person in gets deal" is not basis.

Need define direct-use clause: Prohibits government from introducing Lena's proffer statements in its case-in-chief (affirmative proof of guilt). Does not bar use of leads/derivative evidence, does not bar cross impeachment? Actually direct-use clause "case-in-chief" perhaps allows use in rebuttal? The draft has broad rebuttal clause, but even if no rebuttal clause? In general direct-use clause doesn't bar use in rebuttal if she contradicts? But here separate rebuttal clause. Need distinguish. Need mention does not prevent government from using statements to question other witnesses? Hmm "case-in-chief" only; evidence in government's case-in-chief. But they can use in rebuttal if material inconsistency under clause. It also doesn't prevent use in grand jury? Need perhaps "case-in-chief" is a trial phase; could be used to obtain indictment? Not a "use in case-in-chief"? Need caution: direct-use clause may not apply to pre-trial, sentencing, grand jury? Under proffer agreements maybe direct use limited. The wording "statements will not be used in the government's case-in-chief" likely only at trial, not indictment? Need mention it does not bar derivative use, does not bar cross-exam if opened, does not bar sentencing if clause. Also does not bar use against co-defendants? Actually government may share.

Need derivative-use exposure: Government may use proffer as roadmap to find suppliers, bank records, witnesses, documents, or new charges. If Lena's account of $42,000 market research differs from records, or if she implicates Omar/two officials, the government can use her statements to investigate them and build case. It can also use " fruits" against her? Wait derivative use of her statements against her? The clause says may make any derivative use of information supplied. That means if her statements lead to discovery of evidence, that evidence can be used against her, because not direct use of her own statements. In proffer context, derivative-use waiver means no Kastigar-like immunity. Need explain: Even if statements themselves not introduced, the evidence uncovered because of them can be. E.g., if she identifies a witness or document, the government can subpoena it; if bank records show payments, they can use them. If she changes story at trial, broad rebuttal.

Need rebuttal exposure: Broad clause allows government to use statements to rebut "any evidence, argument, or factual position" offered on her behalf. This is very broad. It could allow: opening statement arguments; cross-exam of Lena and defense witnesses; defense expert or character evidence; sentencing positions. Need explain "materially inconsistent" from governing law? Facts say rebuttal clause may permit use if defendant later presents evidence or argument materially inconsistent. The draft says "any evidence, argument, or factual position" — that may be broader than "materially inconsistent"; it might be triggered by her testifying inconsistently; maybe by defense counsel's argument; maybe by sentencing mitigation. Need caution. Need identify "if at trial Lena says the payments were market research, the government can introduce her proffer statement if she gave a different account, including details/omissions." Need maybe "not just if she lies; if she advances a different factual theory." Need mention "unlimited clause may affect opening statement, cross-examination, defense witnesses, and sentencing." So if defense argues Lena lacked intent, proffer may come in rebuttal. Need be direct.

Need agency-sharing and uncharged-conduct exceptions: The agreement permits sharing with other federal and state agencies. Those agencies are not bound by the direct-use clause unless agreement expressly extends? Need think: The direct-use clause is between Lena and this prosecutor? It says "The government" may share; other agencies may use? Sharing may expose to state prosecution; they may use statements or derivative evidence. Need mention state agencies can bring charges not subject to federal proffer; if no derivative-use restriction, definitely. Need mention uncharged-conduct exclusion: "crimes not previously known to the government are excluded from protection." This is broad and dangerous. Need parse: It says false statements, obstruction, and crimes not previously known to the government are excluded from protection. This means if during proffer Lena admits to any crime not already known to the government, that admission can be used against her (not protected). It also likely if government did not know it before proffer, they can use the statements as direct evidence. Need distinguish: If she says "I knowingly accepted kickbacks" or "I helped falsify invoices" and government didn't already know that specific crime? It isn't protected. This creates impossible catch: "subject" may not know exactly what government knows; if she admits to something they didn't know, prosecution can use it. Need mention even "false statements during proffer" could be used, so don't guess. Need mention "obstruction" can include misleading? Need caution. Need maybe "The agreement's carve-out for 'crimes not previously known' defeats ordinary proffer protection: if you tell the truth and reveal new criminal conduct, the statements can be used directly against you." This is severe. Need maybe "the government may later claim something was not previously known."

Need Omar's status and intended subjects matter. Why? Because contradiction risk and derivative use risk: If Omar has already proffered/pleaded/cooperating, his version may conflict; Lena's statement could be used to investigate her; also if Omar is cooperating, maybe his statements can be used against her regardless. If Omar has not been charged or is target, statements about him could expose her or create false-statement risk. Need perhaps if Omar is a co-defendant, she may have Fifth Amendment? Actually proffer not testimony under oath? Need not. Need more important: If Omar is cooperating, the prosecutor likely already knows facts; they may test Lena's truthfulness. If Lena says Omar told her about kickbacks, and Omar denies or has not admitted, her statement may be used in rebuttal if she later presents defense. If Omar is a target/subject and not cooperating, her statements can provide leads against him; may put her at risk for retaliation? Not legal but practical. Need mention "known participants" status materially affects contradiction and derivative-use risk. Need also mention she needs "topic list" because the draft has no meaningful limitations. Need request "subjects on which the government seeks information" per rule 7; "whether named participant is cooperating"; "nonprivileged statement of client's status"; "what if any evidence contradicts her account" perhaps government not required but can request. Need maybe "prosecutor's statement that session will focus on Omar, consulting payment, and two officials" is too vague; need know names and whether they are targets etc. Need mention if government declines, postpone.

Need include specific written protections/status information to request. Need formulate. Need include that "must be in writing; oral assurances insufficient." Need request:
- Amend proffer to include "no derivative use" / "derivative use immunity": statements and fruits may not be used against Lena in any criminal case, except for perjury/proffer false statements? But if too broad, they won't. Need maybe phrase "at minimum, a derivative-use restriction covering all information and evidence derived from Lena's statements, and a commitment not to share statements/derivative information with other agencies except as necessary for this investigation or with written consent." But agency sharing maybe acceptable? Need include.
- Narrow rebuttal clause: Instead of "any evidence, argument, or factual position" use "narrow, traditional clause: statements may be used only to rebut a defendant's own trial testimony or defense evidence that is directly and materially inconsistent with a specific assertion in the proffer; not opening statements, not sentencing positions, not cross-examination of defense witnesses, and not arguments of counsel." Need be careful: Governing law says rebuttal clause may permit use if later presents evidence or argument materially inconsistent. So can propose "materially inconsistent evidence or testimony offered by Lena, not argument of counsel or sentencing." Need include "no use in sentencing except if she allocutes inconsistently"? If she wants cooperation, government may resist. But exact conditions for later rational proffer could include narrow rebuttal. Need maybe mention if wants to preserve opportunity for sentencing cooperation, perhaps separate plea agreement/cooperation agreement. Need request exact.
- Exclude "crimes not previously known" exception? At least require government to identify in writing the specific known offenses before proffer, or narrow to "false statements, obstruction, perjury" only and "no direct use for other crimes." The agreement should not leave "known" ambiguous. Request list of known subjects/criminal activity. If they won't, decline.
- Include no sharing with other agencies without consent? Or "statements and derivative evidence shall not be shared with/used by state or other federal agencies except for federal prosecution of Lena for offenses identified in the agreement, or unless separately immunized." But if they insist, maybe not impossible, but ask.
- Include "no promise" is unacceptable if Lena wants cooperation credit; get written statement: government will consider/commit to a 5K motion if she provides substantial assistance? Actually no guarantee can be asked? Need not request guarantee, but need understand. Need perhaps "If she wants credit, ask for a written cooperation agreement (proffer-plus/queen for a day) specifying conduct, obligations, and what credit she may receive, or at least a written 'no promises' explanation? The current draft's explicit no promise means no enforceable expectation. The correct course is not assume; obtain actual terms or postpone." Need mention "The fact that no promise is made doesn't itself make attending irrational if goal is to avoid indictment? But no guarantee. But Lena wants cooperation credit; current terms fail."
- Request status info:
   * "Lena's current status: subject vs target? Based on what (nonprivileged) conduct?"
   * "Omar Fenn's status: charged? uncharged? target/subject? cooperating witness? proffer/plea agreement? Does government have his statements? Does it intend to call him?"
   * "The two officials' names and their statuses (targets/subjects/witnesses/cooperating)."
   * "List of topics/subjects/witnesses/documents the government intends to ask about, and the time period/transactions."
   * "Any known inconsistency between Lena's account and evidence/other witness statements? If not, enough to assess."
   * "Whether government will agree that no statements made during proffer will be used in any proceeding against Lena except as permitted by a narrow rebuttal clause and for perjury/false statements."
 Maybe need "ask this in writing and wait for response before session."

Need "What Lena and counsel must not do to investigate Omar's status":
- Do not contact Omar or his attorney? Actually contact co-defendant's attorney maybe if counsel-to-counsel? Rule 8 says defendant should not contact co-defendant or potential witness; counsel must obtain through lawful channels. Could counsel contact Omar's counsel? It says "counsel must obtain information through lawful channels"; contacting Omar's lawyer may be lawful if no no-contact? But "must not contact co-defendant" applies to defendant; counsel may contact other counsel? Need be precise: Lena personally must not call, text, email, meet, or have friends/family contact Omar, former colleagues, North Quill employees, or other potential witnesses. She should not ask the former colleague to "find out" or "confirm" Omar's status; no private investigation. Counsel should not rely on unofficial rumors. If counsel contacts government, that's lawful; can ask prosecutor. Maybe can contact Omar's attorney with a no-contact? But caution: If Omar is represented, contact him directly prohibited by ethics? Actually a lawyer may not communicate with a represented party about the subject matter without consent; but can communicate with their attorney. But should we advise "counsel may consider contacting Omar's counsel through proper channels"? The rule says "Counsel must obtain information through lawful channels." It doesn't prohibit counsel contacting co-defendant's lawyer. But maybe to avoid risk, not necessary. Need mention "do not ask Omar's lawyer without considering conflicts; if he is represented, direct contact is prohibited. Government is proper channel." Hmm better: "Do not investigate through Lena. If counsel believes it is necessary, counsel may inquire of the prosecutor or perhaps Omar's counsel formally; no client participation." But the assignment says "What Lena and counsel must not do to investigate Omar's status" maybe ask what must not do. Need include "Lena must avoid all contact; counsel must not use the proffer session to 'ask Omar' or 'ask around'; counsel may request status from prosecutor; can subpoena? no." Need maybe mention "no contacting grand jury/witnesses to learn testimony" no obstruction? Need be careful not to advise unlawful.
- Need also not destroy or alter records, not "update" story. But they have preserved devices. No ongoing payment. Need maybe "counsel should not interview Omar or the two officials without government/defense counsel approval; that may create obstruction or witness tampering appearance if done improperly."
- Need "Do not use this proffer as a fact-finding expedition to discover Omar's status; don't ask 'what does Omar claim?' in a way that waives? Actually during proffer, if she testifies about their interactions, yes. But if go, she could ask? No. Not relevant.

Need "Whether to attend tomorrow, postpone, or decline":
- Under current terms, do not attend tomorrow. Because decisive terms absent: no derivative-use restriction, overly broad rebuttal, uncharged-conduct exception, no cooperation benefit, no status/topic list; and postponement available. Need recommend postpone, not necessarily outright decline, if these requests can be met. Need mention "postpone rather than attend under terms because attending may waive nothing? Actually if she attends, her statements are protected only as stated; broad provisions create risks. There is no upside absent a deal/benefit. 'First person in' not enough. Postpone until terms/status clarified. If government refuses to provide necessary protections, decline. A later proffer may become rational under exact conditions."

Need "exact conditions under which a later proffer could become rational":
Need state criteria:
1. Lena and counsel obtain written proffer agreement with:
   - Direct-use protection.
   - Derivative-use restriction (no use of statements or fruits in any criminal case against Lena, except narrow false-statement/perjury/obstruction carve-outs).
   - Narrow rebuttal clause limited to "materially inconsistent evidence or testimony adduced by Lena at trial" (or maybe not sentencing/opening).
   - No blanket "crimes not previously known" exclusion, or government specifies in writing known criminal matters; if uncharged-conduct carveout remains, not rational unless limited to using statements about crimes she conceals? Actually standard proffer may allow prosecution for false statements, but not "crimes not previously known." Need ask to remove.
   - Limitation on agency sharing or explicit extension of protections to receiving agencies.
2. Government provides in writing:
   - Lena's status and nonprivileged basis.
   - Omar Fenn's status: target/subject/witness/cooperating/charged/plea/proffer; whether government has his statements.
   - Names/statuses of any known participants/two officials.
   - Topics/subjects and maybe documents/witnesses.
   - What cooperation credit can be offered? Need "government confirms in writing that it will consider or commit to a substantial-assistance motion based on substantial assistance, with objective criteria or at least no promises? Actually 'exact condition' if wants rational: obtain a written promise of what credit she will receive if cooperation is substantial. If not possible, define the path (e.g., proffer agreement with 5K stipulations, or non-prosecution agreement)." Need include. "Do not attend merely to 'get in the door' with no enforceable benefit. A rational proffer requires an actual potential benefit: non-prosecution/immunity/charge reduction/written cooperation agreement/clear 5K possibility." Need maybe "if the sole goal is avoiding indictment, a proffer under current terms might still be rational if she has no defense? But the assignment says Lena wants cooperation credit; rules say no guarantee; the current terms no promise. So condition: she must be willing to proffer without guarantee? Need address perhaps "There could be strategic reasons to proffer even without promise, e.g., to avoid indictment or persuade not to charge. But here she wants credit and the government's terms are too risky. So if she wants to proceed solely for cooperation credit, postpone unless the terms/credit are in writing. If she wants to persuade not to charge, still need derivative-use protection and narrow rebuttal; otherwise, providing account may be used to build a case against her. So not rational under current terms."
Need perhaps mention "proffer is not 'queen for a day' if no derivative-use protection. It is an investigative interview that can be used as roadmap."

Need maybe address "material use questions open" and "co-defendant status unknown" in opening.

Need maybe format as memo to counsel? User says "Counsel Lena on" perhaps answer with advisory. We can write in second person? Use "I recommend..." Need maybe from "Counsel" to "Lena." Need include headings. We need not include legal citations. But maybe mention "Kastigar" if relevant? Probably not necessary. But derivative use concept from immunity law; maybe mention. Need perhaps "under the current terms, the direct-use clause is a narrow 'case-in-chief' promise; it is not immunity." Need define.

Need think through possible issue: "The government may make any derivative use of information supplied." If the agreement says "may" not "will" perhaps broad permission. Need mention "any derivative use" means all leads. Example if she says "my consulting contract is with Fenn's company," the government can subpoena bank records of that company; if records show kickback, they can use them. If she says "the two officials are X and Y," can investigate them; if charges against her include conspiracy with officials, those are derivative. Need mention "This includes derivative evidence that is itself testimonial? Not protected." Need maybe "If she provides documents, those are not statements? Are documents covered? No, physical evidence not protected. Don't bring or produce documents absent subpoena." Good point: In proffer, if she produces records, direct-use clause likely doesn't protect them. Need include? The facts mention devices preserved. Maybe not necessary but useful: "Do not hand over records in a proffer; only statements."

Need think about "rebuttal clause broad: any evidence, argument, or factual position offered on her behalf." In legal terms, this may be overbroad but enforceable if defendant "opens door." Need mention "The government can wait to see defense theory and then introduce her prior proffer statements to contradict even non-testimonial defense arguments. For example, if counsel says in opening 'Lena was a victim of North Quill's fraud,' statements where she described kickbacks could be used." Actually if she did not testify, the prosecutor might use statements in rebuttal. Need "This can effectively waive her right to present a defense? Not exactly, but chills." Need mention if "defense witnesses testify" their evidence can trigger. "At sentencing, if she argues for leniency/acceptance, the statements could be used against her." Need mention "not limited to inconsistent testimony."

Need "The lack of any guaranteed cooperation benefit": Current agreement says no immunity, charge reduction, plea terms, cooperation motion. Under governing law, cooperation credit exists only via written promise or later motion. The prosecutor's invitation "first person" is an inducement not a commitment. Need "Good-faith assistance does not guarantee either; the government may later say her assistance wasn't substantial or was untruthful. She could incriminate herself and get nothing." Need mention if she "believes first person in gets deal" no legal effect; perhaps "market leverage" exists? Need "not enough."

Need "significance of agency sharing and uncharged-conduct exceptions": Need separate headings.

Need "specific written protections and status information to request": Could include a bullet "Before any session, send this letter." Need maybe phrase as "counsel should send a written response to the invitation: (1) request postponement; (2) request amendment; (3) request status disclosure; (4) state no session until terms resolved." That could answer next steps.

Need maybe "No ongoing misconduct and devices preserved": Rule 9 says preservation and stopping misconduct do not require proffer. We can say "So there is no emergency justifying attendance tomorrow; no continuing harm to stop; records already preserved. The only reason for tomorrow is prosecutor's schedule or 'first-in' myth. Neither overcomes risk."

Need maybe "If she declines, can government retaliate? Maybe not relevant; prosecutor can subpoena grand jury; but she has Fifth Amendment right. Need maybe mention "Declining a proffer is not a crime; but it may end cooperation discussions. That's the trade-off." Need perhaps not advise "decline" too glibly; maybe "postpone first, preserve possibility." Need mention "If the prosecution later indicts, she can assert Fifth Amendment at trial? Not exactly. Need not.

Need think about "Omar's status and government intended subjects matter" more nuanced:
- If Omar is cooperating and has given exculpatory or inculpatory statements about Lena, the government may not need her proffer to charge; but they might use proffer to test. The statement could be used to "lock her in" to a version; later if she changes, rebuttal. Need mention "contradiction risk": If at proffer she says one thing, later at trial she gives slightly different account, the government can introduce her prior statement to impeach. If Omar is cooperating, his statement could be used to confront her; any inaccurate guess by her could be treated as false statement. Need "Lena should not guess about Omar or the officials. If she doesn't know, she should say so. But if the government has contrary evidence, they may not reveal; she can still be prosecuted for false statement if she guesses." Actually "false statements during proffer may be used" means if she speculates and is wrong, danger. Need "ask for topics/status first so she can prepare; otherwise she may be pressured to answer without knowing what is true." Need maybe "If Omar has been charged, he may have a Fifth Amendment right, but not relevant."

- If Omar is not charged/cooperating, statements about him could become basis for charges against Lena or lead to him; if he is "known participant" but status unknown, she cannot assess whether the government already knows about the "route open" comment. If government already knows, perhaps no new crime; if not, she may be revealing "crime not previously known" that can be used. The facts: Lena says Omar told her part of invoice revenue shared with people who keep route open. She never reported. This may be evidence of a conspiracy/kickbacks or at least knowledge. If government doesn't know Omar made that statement, admitting it could be "new information" and may be used under uncharged-conduct exception? Wait "crimes not previously known" exception: The statement "Omar told me..." itself isn't a crime she committed unless it shows her knowledge of kickbacks or conspiracy. If she admits she knew about sharing and continued approving invoices, that may be a crime not previously known? It could be known? Actually government might not know that she knew. This is critical. Need highlight: "The $42,000 is the suspected bribe. Saying it was market research is exculpatory. Saying Omar told her about revenue sharing could establish knowledge or deliberate ignorance; if the government did not already know she had that knowledge, the admission may be outside protection and used directly against her." But is "the payment" and "false invoices" already under investigation; the "route open" statement goes to knowledge. If uncharged-conduct exception says "crimes not previously known" not "facts" - if the crime of conspiracy/kickback receiving is known but her knowledge not known, admission can be used to prove it. Need mention. This is a huge reason to know status/topics before proffer.

Need "unlimited rebuttal" could apply because "evidence, argument, or factual position offered on her behalf": If she later argues she lacked knowledge, the proffer statement where she described Omar's comment could rebut. Need connect.

Need perhaps include "The government's focus on Omar, consulting payment, and two officials" is not enough; if they won't identify the officials, she may unknowingly discuss matters not in intended subject list. Need "At least get the names of the two officials and what they are alleged to have done. Otherwise, she cannot protect herself or assess conflicts." Need maybe "if the government says names are grand-jury secret, rule 7 says it need not reveal protected grand-jury evidence, but may provide nonprivileged status; it is not required to reveal. If not, postpone? Need perhaps "The government need not reveal grand-jury evidence, but can state whether Omar is cooperating and topics. If they refuse even nonprivileged status, attend would violate rule 10."

Need perhaps mention "Rule 10: when decisive fact missing, obtain it or postpone rather than assume favorable." Need explicitly apply: "Do not assume Omar is not cooperating or that the government won't share with state prosecutors. Do not assume 'first person in' will produce credit. Obtain terms/status."

Need maybe mention "No 'material use' of statements outside direct? There is no 'use' limitation. Need not.

Need maybe discuss "proffer agreement is contract, construed against drafter? Maybe not; don't rely." Need maybe "Oral representations by prosecutor not effective; only written agreement applies." Need mention "If prosecutor says 'we won't use it except as written,' don't rely." Actually under rule 1, only written agreement protections. Need mention.

Need maybe "Lena's current status as 'subject' means not target? In DOJ terms, subject is person whose conduct is within scope but not yet target. It can change. The draft no promise. Need not attach much weight; status can change after proffer." Need mention "A 'subject' invitation is not a promise to stay subject; she can become target." Need perhaps "The prosecutor's statement that session will focus on Omar etc. may mean Lena is a witness or a target; unknown." Need mention.

Need maybe "false statements and obstruction carve-out" — Need advise "Do not lie, do not speculate, do not guess; if uncertain, say 'I don't remember' or 'I need to check,' but be careful if answer changes later. Saying 'I don't remember' could be false statement if knowingly false. But if memory refreshed later, use?" Need maybe "A proffer is not testimony under oath? But false statements may be used anyway; maybe 18 U.S.C. 1001? Need mention. Need advise "If she does attend after protections, prepare thoroughly; but if not, no."

Need maybe "No ongoing payment" means no need to stop misconduct; preservation done. If there were ongoing misconduct, must stop regardless of proffer. Here none, so no urgency.

Need maybe "Should she provide the full account? No until terms resolved. Under rule 6, counsel should not reveal client's full account until counsel understands statuses. This maps to question: don't let Lena tell all in proffer without status/topics. Need include "Do not have Lena rehearse/proffer to government or provide a 'white paper' in advance."

Need maybe "The proposal leaves material use questions open and status of co-defendant unknown." We need advise. Need maybe "Because the prosecutor has not responded to narrower language but has not said can't postpone, the right move is to postpone and seek modifications; if they decline, decline." Good.

Need maybe "Exact conditions under which a later proffer could become rational" not just terms but "after status is known and Lena decides to tell truth." Need maybe "Rational if: (a) she can make a knowing decision because written terms/status provided; (b) the proffer has a realistic benefit such as a written cooperation/charge-reduction agreement, non-prosecution agreement, or at least a documented 'safety valve' if the district has an informal but reliable policy? But governing law says cooperation credit only through written promise or motion; rational from her perspective need some benefit. If no promise, maybe only to persuade prosecutor not to charge; but should still be informed." Need maybe "If the government refuses to give any promise, rational only if the downside is capped by derivative-use/narrow rebuttal protections; otherwise no." Need include "If she decides to attend later, she should only answer truthfully and not provide documents; if she doesn't know something, says so." Wait "exact conditions" maybe include "counsel can prepare by reviewing records; no need to wait if decisive facts obtained." Need phrase.

Need maybe "cooperation credit under supplied sentencing rules": "If the supplied sentencing rules include USSG 5K1.1, only the government can move for substantial assistance. The draft explicitly does not promise a motion. A court cannot grant a departure based solely on her cooperation unless the government moves (except statutory mandatory minimum safety valve, not applicable? Not in facts). Need maybe mention "Do not assume 'substantial assistance' will be found; the government defines it." Need perhaps "In the absence of a written promise, she has no contractual right and no judicial remedy to compel a motion." Need mention "maybe if a prosecutor's promise could be enforceable under contract law? But the agreement says no promise; not here." Need maybe "Even a signed cooperation agreement can be discretionary; but at least it would define the benefit."

Need maybe "Agency sharing with state agencies: if state prosecutes her, the federal direct-use clause may not bind state; state may use statements? Need nuance: The state is a different sovereign; contract between Lena and federal government may not bind state unless agreement expressly says it binds agents/agencies or they adopt it. The sharing clause expressly authorizes, so state can use statements/derivative evidence. This is especially dangerous if there are state law offenses (bribery, kickbacks). Need mention."

Need maybe "uncharged-conduct exception maybe means if she admits to tax evasion (not previously known), IRS can use; if she admits to mail fraud not previously known, direct. The agreement reserves false statements, obstruction, perjury, and 'crimes not previously known'. It is a giant loophole." Need perhaps "The 'crimes not previously known' exception may swallow the direct-use protection: any inculpatory admission can be characterized as a crime not previously known. Ask to delete or replace with a list of known offenses; otherwise no protection." Good.

Need perhaps "Do not attend tomorrow due to the prosecutor's refusal to respond? They asked once; no response. Maybe they didn't have time? The prosecutor hasn't said can't postpone. So request postponement in writing. If they respond with adequate terms/status, set a new date. If no, don't attend."

Need perhaps "If she attends tomorrow under current terms, what exactly could happen?" Could be:
- If she gives exculpatory account ($42k as market research) and implicates Omar ("shared with people who keep route open"), government can use this to investigate the two officials and maybe charge her with conspiracy or bribery, because "crimes not previously known" / derivative use. It can share with state.
- If later she is charged and mounts a defense (e.g., "I didn't know invoices were false" or "no corrupt intent"), government can use her proffer statements as rebuttal. If she testifies, can impeach.
- If she lies/omits, false statements/obstruction can be used directly.
- She may get nothing in return: no cooperation motion, no charge reduction, no immunity. She may be "first in" but with no deal.
Need maybe include in a "bottom line."

Need maybe "What does 'materially inconsistent' mean? Under broad clause, perhaps lower threshold. Need perhaps "if evidence or argument offered on her behalf creates any inconsistency, not just direct contradiction; 'any factual position' includes her defense theme. Need mention."

Need maybe "The direct-use clause protects statements only from 'case-in-chief'. It doesn't protect against investigative uses, grand jury, pretrial motions, sentencing, or other sovereigns. The government can use her statements as 'road maps.' Need mention "case-in-chief" is not "any use" or "use in any criminal proceeding"; compare to immunity." Good.

Need maybe "The proposed agreement's sharing clause says government may share proffer information with other federal and state agencies. This is a derivative-use issue by itself; even if they somehow didn't use in case-in-chief, state can." Good.

Need maybe "What about 'status of co-defendant unknown' — 'subject' vs 'target'? Need know whether Omar has a lawyer? Need maybe "Ask nonprivileged: has Omar been indicted/information? Has Omar entered into a cooperation agreement? Has Omar provided statements? Is he expected to testify at any trial? Has he been granted immunity? Are there sealed charges? They may not answer if grand jury secret, but can answer whether he is represented? Hmm can ask "Is Omar Fenn represented by counsel?" But maybe too sensitive. Need mention "lawful channels: ask prosecutor and perhaps the court docket; if charges filed, dockets are public. Run a criminal record/docket check; but no witnesses." Need maybe "Counsel can check public dockets, indictment databases, plea calendars, media? This is lawful. But don't ask Lena to contact people." Good.

Need maybe "What Lena and counsel should not do to investigate Omar's status" maybe includes "Do not rely on the former colleague's hearsay; do not ask the former colleague to get more information; do not contact North Quill, Omar, his family, employees, or the two officials; do not ask Lena's friends to make inquiries; do not approach grand jury witnesses; do not send investigator to interview potential witnesses without understanding conflicts and obstruction risk; no pretexting. Instead, ask government in writing, check public records, consider formal discovery if charges filed." Need include "not to contact co-defendant or potential witness" expressly.

Need perhaps "What if Lena already has no ongoing payment? No need to attend to stop; if she is continuing to receive payments or involved in covering up? She must stop immediately, irrespective; but not here. Need maybe "If she has not already stopped contact with Omar/North Quill, stop; do not solicit info." But facts say no ongoing payment; not necessarily no contact. Need maybe "Don't contact them to ask about the investigation."

Need perhaps "What if the prosecutor says 'postponing will hurt her'? The 'first person in' is not legal; proffer credit can occur later if genuine substantial assistance; but maybe first-person benefit exists in practice. Need mention "Even if first-in helps, it cannot be weighed without knowing terms. If government later claims she wasn't first because someone else came in, she has no remedy." Need maybe "There's no enforceable right to 'first in' deal." Good.

Need perhaps "Do not have Lena sign a waiver of her Fifth Amendment? Wait proffer agreements often include voluntary waiver of Fifth Amendment? Hmm not in facts. Need not. But if she attends and answers questions, she may be waiving privilege as to those statements? The agreement governs use; but actual statements can be used if carve-outs. It is not compelled. Need maybe "She can invoke Fifth Amendment during proffer? If she does, it may end cooperation. But not relevant. Need not.

Need maybe "Under governing law, proffer not immunity/plea/cooperation credit" Need cite rule 1. Need maybe "The written agreement would be construed solely as contract; no implied promises. Need not.

Need maybe "The government is not required to reveal grand-jury evidence, but can give nonprivileged status. Ask anyway. If they refuse, rule 10 says postpone." Good.

Need maybe "Exact conditions later rational" should be practical and perhaps in a checklist. Need perhaps "Only attend a later proffer if all of the following are true:" Use bullets. Need be thorough.

Potential structure:
1. Summary recommendation
2. What the current direct-use clause protects / not
3. Derivative-use exposure
4. Rebuttal exposure
5. No guaranteed cooperation benefit
6. Agency sharing and uncharged-conduct exceptions
7. Omar's status and intended subjects
8. Specific written protections and status info to request
9. What not to do
10. Whether to attend / conditions for later proffer

Need maybe not overly long? Desired oververbosity 5; but prompt complex. Need provide enough detail. Maybe around 3000-4000 words? We can produce maybe 2500. Need include all points. User asked in detail. Let's draft with headings and concise bullets.

Need think about legal accuracy nuance:
- "Direct-use clause barring use in case-in-chief" Does it bar use in grand jury? A case-in-chief is trial. The government can use statements before grand jury to indict; if it introduces no statements at trial, no violation. But if derivative? yes. Better say "It does not bar use in grand jury or other pretrial proceedings unless separately stated." But is "case-in-chief" perhaps limited to "government's affirmative case at trial" and not "rebuttal"? Usually yes. Need mention.
- "Rebuttal clause may permit use if defendant later presents evidence or argument materially inconsistent with proffer." The draft says "any evidence, argument, or factual position" "offered on her behalf" can be rebutted. Need "could permit use if defense counsel's opening or closing argues she was naive, even if Lena does not testify." Need cautious: "may" under governing law; courts enforce broad clauses? Need phrase "At least it threatens/ likely permits." Need not definitively say. Could say "the draft appears designed to permit" and "counsel should assume it would be enforced according to its terms." Need mention "unlimited clause may affect opening statement, cross-examination, defense witnesses, and sentencing." That is enough.

- "Uncharged-conduct exceptions" Under rule 4, statements concerning separate offenses, false statements, obstruction, perjury may be used if agreement reserves those subjects. The draft reserves "crimes not previously known to the government" — This is weird; "separate offenses" maybe any offense not previously known. Need say "If she admits to a previously unknown crime, the direct-use bar does not apply; the admission can be used as direct evidence." Maybe "previously known" to whom? Entire government? state? Need ambiguity. Need ask to define. Good.
- "Agency sharing": The direct-use clause binds "government" but if shared, are states bound? Maybe if they are "government" within the agreement? The agreement says "federal and state agencies"; likely they receive statements. If no derivative-use bar, state can use. Need mention "The sharing clause is not just confidentiality; it is a use authorization. Even if a state agency is considered part of 'government' for direct use, after sharing, the statements may become part of state investigation and be used in state prosecution if not barred." Need perhaps "Ask for express commitment from each receiving agency or delete sharing." Good.

- "Omar status" Need maybe "If Omar is a cooperating witness, the government may already know the answer to questions. Lena's proffer will be judged against his account. If she tells the truth consistent with him, perhaps okay; if inconsistent, she may be treated as not cooperating or false. If she implicates him and he is not cooperating, she may be making statements against a third party that can be used in his prosecution (and maybe against her if conspiracy)." Need maybe "If he has been charged, he has a lawyer; any contact by Lena could be witness tampering/obstruction." Good.

- "No guaranteed benefit" Need "The current clause 'No promise of immunity... motion' is actually helpful for clarity: no contract. Lena should not think 'first person' creates any legal rights. If she wants credit, a written proffer agreement plus a separate cooperation/plea agreement would be necessary. The government may make no promises prior to proffer because it doesn't know if truthful. That's normal; but then attending is an act of trust. Need balance. Need maybe "A rational proffer may be to earn a motion later; but without derivative-use protection, the downside may exceed upside. If government says 'we can't promise credit before hearing you,' that's common; but then it can still offer a proffer agreement with protections. Need request."

- Need maybe "Do not reveal client's full account until counsel understands statuses" (rule 6). Need include "Counsel should not ask Lena to tell her full story in preparation for the proffer? Actually counsel needs to know the facts to advise; but rule 6 says counsel should not reveal client's full account to the government until statuses known. Not that counsel shouldn't know. Need phrase correctly: "Do not let Lena provide her full account to the government, and avoid submitting a proffer letter summarizing her account, until the statuses and terms are resolved." Need perhaps "In private, counsel should know the facts, but should not disclose to government." But the assignment might be from counsel? It says "Your role: You represent Lena" and "Assignment: Counsel Lena" maybe write to client. Need include "In preparing, counsel must understand the facts from Lena before making decisions; but don't disclose a detailed proffer in writing to government before an agreement." Need maybe "Don't have Lena provide an oral 'informal proffer' over the phone now." Good.

Need perhaps "No ongoing misconduct and records preserved" — "therefore no need to proffer immediately to stop harm; if there were ongoing false invoices/payments, she must stop immediately and preserve, independent of proffer." Good.

Need maybe "The draft says 'The government may share proffer information with other federal and state agencies.' That may conflict with 18 U.S.C. 201? Not. Need not.

Need maybe "Ask for a witness/topic list beyond 'Omar, consulting payment, two officials.' Need "names of two officials" specifically. If they claim grand jury secrecy, ask for nonprivileged "status" not "evidence." Need "The prosecutor's statement is insufficient to allow informed consent." Good.

Need maybe "If no response to the requested changes, what does silence mean? Under rule 10, do not assume favorable; assume the worst." Need include "The fact that the prosecutor has not responded means no modifications; attend only under existing terms? No." Good.

Need perhaps "What if prosecutor cannot postpone due to trial? Facts say hasn't said cannot. So ask. If a trial or grand jury deadline is imminent, they can say; then reassess." Maybe not necessary.

Need maybe "Should Lena decline entirely?" Could answer "Postpone, not necessarily decline, because a modified proffer could be rational. If the government refuses the necessary modifications/status, decline." Need avoid ambiguity: "Do not attend tomorrow." Good.

Need maybe "Exact conditions under which a later proffer could become rational" perhaps use "only after" and maybe "unless she and counsel are willing to accept high risk for no guaranteed benefit." Need be exact. Need include "She must be genuinely prepared to tell the truth; a proffer under false pretenses is dangerous." Good.

Let's draft with headings and bullet points. Need perhaps "I. Summary" no, "Below." Need maybe use "You" to address Lena? Since role as counsel maybe "I advise." Let's produce.

Let's outline in detail:

Start:
"Lena should not attend tomorrow under current terms. The session should be postponed until (1) the written agreement is amended to limit derivative use and rebuttal, and the carve-outs are narrowed/clarified, and (2) the government states in writing the nonprivileged status of Lena, Omar Fenn, the two officials, and the intended topics. If those conditions cannot be met, decline."

Then sections:

A. Current direct-use clause:
- Only prohibits trial case-in-chief introduction of statements.
- Not immunity; no protection in grand jury/pretrial/sentencing? Actually case-in-chief only; but if used in grand jury, not direct case-in-chief. Need "No automatic exclusion at other phases."
- It doesn't cover evidence derived; doesn't stop leads; doesn't bind state; doesn't bar rebuttal.
- It can still be used for impeachment/rebuttal under draft clause if inconsistency; not protected from sharing.

B. Derivative-use:
- "Any derivative use" express waiver of derivative-use immunity.
- Government can "follow her leads": subpoena records, interview witnesses, find evidence, develop charges against her and others.
- If she says $42k was market research, government investigates; if finds contradiction, uses it in case-in-chief because not her statement? Actually if evidence is "derivative" from her statement, direct-use clause doesn't apply. Need phrase.
- Example "if she identifies 'two officials' names, they become investigative targets; if that produces a co-conspirator statement, it can be used against her."

C. Rebuttal:
- Draft clause extraordinarily broad. "Any evidence, argument, factual position offered on her behalf" could trigger from opening statement, cross-examination, defense witnesses, closing, sentencing.
- If at trial she argues no knowledge/kickbacks, proffer can be admitted to show prior contrary statements.
- This chills defense and creates risk if her account is incomplete or imprecise.
- The direct-use clause's protection disappears once she contests charges in any way.

D. No guaranteed cooperation benefit:
- No promise of immunity/charge reduction/plea/cooperation motion. Under rules, only written promise or later motion can produce credit.
- "First person in" is not an enforceable deal; no remedy if she cooperates and gets nothing.
- If she wants cooperation credit, she should have written cooperation/plea or at least explicit prosecutor commitment? Need maybe "or at least a written protocol for evaluating and moving for substantial assistance." But exact condition.

E. Agency sharing and uncharged conduct:
- Sharing with other agencies undermines federal limitations; state may use. Unless receiving agencies adopt limitations, no protection.
- "Crimes not previously known" exception: any admission of new conduct can be direct use; ambiguity about what "previously known" means; if government didn't know her knowledge of route sharing, direct use. This is especially dangerous.
- False statement/obstruction exception: any misstatement/speculation can be used. She should not attend until prepared and terms not exposing her to false-statement trap.

F. Omar status and intended subjects:
- Need know whether Omar is target/subject/witness/cooperating/charged; whether he has proffered/pleaded; whether he denies her account. This affects:
   * Contradiction risk: if he is cooperating, government can compare; if her account differs from his, they may view as noncooperation/false.
   * Derivative use: if he is uncharged, her statements can be used to build case against him/her.
   * Self-protection: she shouldn't speculate. If she doesn't know if Omar's statement "shared with people who keep route open" is known, admitting it may expose new knowledge. Need ask.
- Prosecutor's vague "focus on Omar, consulting payment, two officials" insufficient. Need names/status/topics.
- "Lena is subject" can change; no assurance.

G. Specific written protections/status to request:
Need list:
1. Written response to request for postponement.
2. Amendment of proffer:
   - Direct-use plus derivative use: "No statements or evidence derived from them will be used in any criminal proceeding against Lena by any federal/state agency, except in prosecution for false statement/perjury/obstruction, and only if the statements were knowingly false/material and the crime is specified." Maybe "If government won't agree to full derivative-use, at least no lead use and no use in case-in-chief/other proceedings"?
   - Rebuttal limited to "Lena's own trial testimony or evidence she actually introduces that is directly and materially inconsistent with a specific statement in the proffer; no use in opening/closing statements, no sentencing, no defense witnesses solely because of the defense theory."
   - Delete or narrow "crimes not previously known" exception; require government to list known offenses before proffer; any new admitted crimes not to be used directly absent independent evidence? Hmm "proffer" usually protects new crimes except some? But if she wants credit, she may need to disclose. Could request "new crimes disclosed during the proffer may only be used/derivative under conditions" but government may not agree. But we can say "if not deleted, at minimum the government must provide written list of already-known criminal matters, so the exception cannot be used unfairly." Need note "If they will not narrow, not rational for her."
   - Agency-sharing limitation: "No sharing with other agencies unless those agencies agree in writing to be bound; or if sharing needed, receiving agencies cannot use statements/derivatives except in federal case."
   - "No documents/production required; only statements; if records needed, subpoena/counsel process" optional.
3. Status information:
   - Lena's status and basis.
   - Omar Fenn: charged/uncharged, target/subject/cooperating witness, proffer/plea, whether government has his statements, whether he denies her account.
   - Names/statuses of the two officials.
   - Topics/witnesses/time frame.
   - Whether the government has evidence contradicting her market-research account? Maybe ask "nonprivileged indication" not necessarily.
   - What potential cooperation credit could be (written).

Need perhaps "Ask for these in writing and wait for reply."

H. What not to do:
- Lena must have no contact with Omar, North Quill employees, former colleagues, the two officials, or potential witnesses. No third parties on her behalf. No "asking around" about whether Omar is cooperating. No checking his social media? That may be okay? Hmm contact? Need not. But "not contact" is enough.
- Counsel should not use proffer session as discovery; don't ask Lena to elicit info from witnesses; don't have Lena send messages to Omar.
- Do not disclose full account to government before status/protections.
- Do not destroy or alter records; preserve (already done).
- If there is any ongoing scheme/payment, cease immediately, without relying on proffer.

I. Whether to attend:
- No. Attend only after conditions met. Use written postponement. If government refuses to provide minimal protections/status, decline. The cost of attending too high: she may incriminate herself, lose defense, no benefit.

J. Conditions later rational:
- Need "all of the following":
   1. She and counsel have written proffer with derivative-use restriction and narrow rebuttal; known-offenses list or removed uncharged-conduct carve-out; agency sharing limitation; no false statement trap.
   2. Government states in writing:
      - Omar's status; the two officials; intended subjects.
      - Any cooperation benefit/credit (even if no guarantee, explain why Lena is attending).
   3. If Lena seeks cooperation credit, there is a written cooperation/plea agreement or at least a clear written path to a substantial-assistance motion (or non-prosecution agreement), not just "first in."
   4. Lena is prepared to give a complete, truthful account, and counsel has reviewed relevant records (market research, consulting agreement, invoices, bank records) before any statements.
   5. No ongoing misconduct; records preserved; if not, steps already taken independent of proffer.
- If these cannot be met, decline.

Need perhaps "if government won't promise credit, but offers proffer with strong protections, she could still attend to seek non-prosecution? But condition says rational only if there is a realistic benefit; maybe "a documented statement from prosecutor of what will happen if cooperation is substantial" enough. Need include "a rational proffer is not necessarily one with guaranteed benefit; it can be one where the potential benefit (e.g., avoidance of charges, 5K motion) exceeds the risk and the risks are capped by written terms." This nuance is good. Need perhaps phrase: "A later proffer can be rational if the downside is capped and the upside is real and stated." But "exact conditions" maybe "if no guarantee, at least the government has said in writing that it will consider a cooperation motion and the agreement protects her; otherwise no." Let's include.

Need maybe incorporate "good-faith assistance does not guarantee" but if she wants cooperation, maybe "cooperation credit exists only through written promise or later motion." Need perhaps "A rational proffer could be made without written promise if the proffer itself is designed to earn a 5K motion; but the legal risk is acceptable only with protection. So condition: written protection + clear statement of possible credit; not a binding promise if impossible." Good.

Potential issue: Under "supplied sentencing rules," maybe there is a "safety valve" under 18 U.S.C. 3553(f) that allows court to sentence below mandatory minimum if defendant truthfully provides all info, no motion needed. But the problem says "under the supplied sentencing rules" maybe refers to guidelines only. Need not mention safety valve. But if there is a mandatory minimum, proffer could be rational for safety valve even without cooperation motion. But facts didn't mention charges. Don't bring.

Need perhaps "No ongoing payment is occurring" so no need to act to stop; but "preserving records and stopping ongoing misconduct do not require proffer" maybe if there is ongoing misconduct, stop now and preserve. Need include "If Lena has any ongoing involvement with North Quill, she should cease immediately and not wait for a proffer letter." Good.

Need perhaps "Lena says the payment was legitimate market research" — she may have evidence (reports, emails). Need counsel should collect to prepare. "Before any proffer, counsel should review all documents, including consulting agreement, market research deliverables, invoice approvals, and bank statements." Need include in conditions. "If the market-research claim is false, attending under any terms is very dangerous; but if true, still need protections." Maybe not necessary. But "exact conditions" include "counsel investigates facts." Need mention "Do not put Lena in proffer until counsel has her account and documents; otherwise she may make inaccurate statements."

Need perhaps "Status of Omar as co-defendant" — facts say co-defendant? It says "status of a co-defendant is unknown" and "Omar Fenn, North Quill executive." The initial says co-defendant? Actually "status of a co-defendant is unknown." Is Omar a co-defendant? "Co-defendant" maybe not charged; but question says co-defendant. Need perhaps "calls him a potential co-defendant/potential witness. Do not use 'co-defendant' as fact." Need not.

Need maybe "Lena's current status as 'subject' in invitation" — Need advise "subject is not target, but can change." Good.

Let's produce final in a clear memo style. Need maybe "The current draft is a one-way information-gathering tool." Nice.

Need ensure no unsupported legal claims. The governing law says "rebuttal clause may permit use ... if defendant later presents evidence or argument materially inconsistent with proffer. An unlimited clause may affect opening statement, cross-examination, defense witnesses, and sentencing." So our statements align.

Potential issue: "A direct-use clause barring use of statements in government's case-in-chief does not bar government from pursuing leads, witnesses, records, or charges derived from statements unless derivative use is also restricted." This exactly. Need maybe use "leads, witnesses, records, or charges" language.

Potential issue: "The government need not reveal protected grand-jury evidence, but counsel may request a nonprivileged statement..." Need not say "prosecutor must answer." Need "request, not demand; but if refused, postpone." Good.

Need maybe "A defendant should not contact a co-defendant or potential witness to learn cooperation status. Counsel must obtain information through lawful channels." Need not mention "do not contact via social media" but can.

Need perhaps "If the prosecutor says not possible to postpone, then decide if terms are adequate; under current terms still should decline unless terms improved. The lack of postponement isn't a reason to waive important rights." Good maybe.

Let's draft final with headings.

Need maybe "This memo assumes the facts and governing-law rules are accurate; if any additional oral assurances from prosecutor, they do not count unless written." Nice.

Let's write:

"Lena should not attend tomorrow's proffer under the current draft. I recommend a written request to postpone and a written list of modifications/status requests. If the government will not provide them, decline."

Then detailed.

Need perhaps "what current direct-use clause protects and does not protect" exact:

- Protects: "Your statements cannot be introduced by the prosecutor during its initial case at trial to prove you guilty." It might also prevent "use" by that prosecutor in case-in-chief? Not broad.
- Does not protect: "It does not stop the government from investigating based on what you say; from using the statements in grand jury to get indictment? Wait if case-in-chief is trial, but grand jury use is use. Need perhaps "not by its terms." Need phrase "does not stop use before a grand jury, in pretrial hearings, at sentencing, by another agency, or in rebuttal after a defense is offered." Need maybe "pretrial hearings" could be "uses" but direct-use clause only bars case-in-chief. If a motion hearing? Maybe yes. Need not overemphasize if not necessary. But okay.

Need perhaps "does not protect physical evidence, documents, or fruits." Good.

Need maybe "rebuttal exposure" example:
- If she attends and says "I never knew invoices were false; I thought the $42K was market research," and later at trial defense argues "Lena lacked intent," government can use her proffer statements if they include any different detail. If her proffer includes "Omar told me revenue was shared with people who keep route open," that destroys lack-of-knowledge defense. Need include. This is key.

Need maybe "derivative exposure example":
- "If she says the consulting contract was with Fenn's company and that company had a separate account, the government can subpoena that account; if it shows a kickback chain, the records can be used against her. The clause allows this." Good.

Need maybe "uncharged conduct exception" maybe:
- "Any statement that reveals a crime not already known to the government is outside protection. The exception is broad, and the agreement doesn't define 'previously known' or which agency/agent. The government could later argue it didn't know Lena had knowledge of the 'route open' arrangement before the proffer and use her admission to prove bribery/conspiracy." Good.

Need perhaps "Omar's status" maybe:
- "If Omar has already cooperated, the government has a benchmark. If Lena's account doesn't match, they may claim she is not being candid. If Omar is not cooperating, Lena's account naming him may be the only evidence linking him, and it may also establish her knowledge or participation. If he is charged, it is especially important not to contact him; any contact could be viewed as obstruction/tampering." Good.

Need maybe "requested status info" perhaps "counsel should write: 'We cannot proceed until you confirm: (1) Is Omar Fenn charged, and if so with what; is he cooperating; has he proffered; (2) who are the two officials and what is their status; (3) what topics/witnesses will be covered; (4) what is the nonprivileged basis for Lena being a subject; (5) whether the government has evidence contradicting her anticipated account; (6) what credit, if any, can be put in writing.'" Good.

Need maybe "What Lena and counsel must not do" perhaps:
- "Lena should not call, text, email, meet, or send anyone to contact Omar Fenn, North Quill employees, former colleagues, the two officials, or any witness. No 'ask around,' no social-media messages, no third-party inquiries. She should not attempt to obtain Omar's grand jury testimony or cooperation status through friends."
- "Counsel should not ask Lena to contact anyone either. Counsel may use lawful means: ask the prosecutor, check public dockets, and if charges are filed, use discovery."
- "Do not present a full written or oral account to the government before terms are fixed."
- "Do not delete, alter, or destroy records." Actually "devices are preserved" maybe "continue to preserve; don't alter." Good.

Need perhaps "conditions for later rational" maybe "If all four/five conditions are satisfied, then attending may be rational; but there remains no guarantee of credit. If Lena's goal is to obtain cooperation credit, she should ask for a separate written cooperation agreement or, at minimum, a 'queen for a day' agreement with derivative-use protection and an explicit mechanism for evaluating a 5K1.1 motion. Without that, she is an information source, not a cooperator with rights." Good.

Need maybe "if a later proffer becomes rational, exact conditions" include "the government's response is in writing." Good.

Let's ensure answer not too repetitive. But prompt asks all. We can be organized.

Potential issue: "Counsel should not reveal client's full account until counsel understands whether known participants are targets, subjects, cooperating witnesses, or uncharged persons when that status materially affects contradiction and derivative-use risk." In our advice, "before a proffer, counsel must know the facts to advise. But don't reveal to government." Actually rule says counsel should not reveal client's full account until statuses understood. We can mention. Need perhaps "No 5K letter or proffer summary" before statuses. Good.

Need maybe "If current terms no promise of immunity, charge reduction, plea terms, or cooperation motion" — If she wants "cooperation credit" perhaps perhaps there is a "proffer agreement" that is not a "cooperation agreement." Need "Do not sign a 'proffer agreement' thinking it's a cooperation agreement." Good.

Need perhaps "material use questions open" maybe "The draft is materially adverse on all key use questions." Good.

Let's draft final now. Need perhaps with "To: Lena" but not necessary. Let's write in a formal advisory style. Include "I. Do not attend tomorrow." Then sections. Need maybe use "current draft" not "current terms." Good.

Let's ensure all bullet points are covered. Need maybe count: direct use, derivative, rebuttal, no benefit, agency sharing, uncharged, Omar, status, not do, whether attend, conditions. Yes.

Let's formulate final answer with perhaps 3,500 words? Oververbosity 5; maybe 2,800. Fine.

Need be careful in "direct-use clause does not protect against use in grand jury" — Is that necessarily true? A "case-in-chief" term doesn't bar grand jury use by its terms. But the grand jury may indict based on statements; if later at trial not used, no issue. Need phrase "does not, by its terms, bar use in a grand jury or other non-case-in-chief setting." Good.
Need "pretrial hearings" maybe if statements used in motions? A direct-use clause at arraignment? "case-in-chief" specifically trial. Could use at suppression? Maybe yes. Good.

Need perhaps "rebuttal clause" and "case-in-chief" interplay: If government uses statements in rebuttal after defense, that's after case-in-chief? Usually rebuttal is part of trial but not "case-in-chief." The draft separately permits. Need mention "The direct-use clause's protection is therefore very small." Good.

Need perhaps "material inconsistency" under broad clause: Need mention "even if the statement is not inconsistent in a direct way, the government may argue any 'factual position' is inconsistent." Good.

Need perhaps "uncharged-conduct exceptions" "This is not standard proffer protection; it could swallow the rule." Good.

Need maybe "Omar's status if he is a co-defendant" "If he has been charged, there may be a public docket; counsel should check. If a case is sealed, ask government." Good.

Need maybe "No promise of cooperation credit" "There is a difference between 'cooperation' (helping) and 'cooperation credit' (legal benefit). The draft allows the former but promises none of the latter." Nice line.

Need maybe "the government may share proffer information with other agencies" "They may share it; if they share it, those agencies may not be parties to the agreement. Ask for written assurances." Good.

Need perhaps "If the government cannot give a response by tomorrow, postpone; if they refuse to postpone, decline." Good.

Let's write final.
