We need answer legal/procurement protest plan. Need be precise. Need parse. User asks ordered protest plan addressing bullet points. Need apply facts and rules. Need maybe note dates. Need determine deadlines, automatic stay, agency protest effect, grounds, etc. Need be careful: Need calculate calendar days; Board open relevant dates; day knowledge excluded; deadlines; automatic stay. Need produce ordered plan.

Let's label facts:
- Award notice Wed Sept 1, 2027.
- Debrief Sat Sept 4, same day receives slides. Today Tuesday Sept 7.
- Agency protest proposed Sept 10; agency no written suspension. Atlas transition starts Sept 13.
- Solicitation defect: openly required 5 yrs polar experience; Silverline had 3 and submitted without protest; now argues unnecessarily restrictive. Rule 1: apparent solicitation defect must be filed before bid deadline; bidder submits without timely protesting obvious term waives ground. So this ground waived; should not include as merits ground maybe can mention? It says waived. Need address.

Post-award grounds first disclosed at debriefing:
1 Atlas credited sensor-resolution score based on model Atlas did not identify in proposal.
2 Subcontractor experience treated as zero despite clause "will be considered."
3 Price higher by 1.8M but selected based on disputed technical scoring.
Debriefing required? Held required debriefing; first disclosure. Rule 3: required debriefing delays knowledge of matters first disclosed there. It does not revive apparent solicitation defect. So known on Sept 4? The day of knowledge excluded. They received written slides same day. Need ten-calendar-day Board merits deadline. Rule 2: Post-award protest to Board within ten calendar days after knew or should have known basis. Day of knowledge excluded. Knowledge Sept 4 Sat. Exclude Sept 4; count Sept 5? Need count 10 calendar days. Let's calculate. If day of knowledge = Saturday Sept 4 excluded, first day = Sunday Sept 5? Calendar days include weekends. Count: Sept 5=1, 6=2, 7=3, 8=4, 9=5, 10=6, 11=7, 12=8, 13=9, 14=10? Wait if ten calendar days after, and day of knowledge excluded, deadline end day 10 is Sept 14 (Tuesday). If due next open day if closed; Board open all dates. So merits deadline Tuesday Sept 14. Need be careful: if "within ten calendar days after ... knew" using Federal Rule? Excluding day of knowledge, 10th day maybe Sept 14. Yes.

Automatic stay:
Rule 4: Award performance automatically stayed only if Board receives protest by later of:
(a) ten calendar days after award notice; or
(b) five calendar days after required debriefing.
The triggering day is excluded.

Need compute both trigger days:
Award notice Wed Sept 1. Exclude Sept 1. Ten calendar days after award notice: Sept 2=1, 3=2, 4=3, 5=4, 6=5, 7=6, 8=7, 9=8, 10=9, 11=10? Wait ten days after Sept 1 excluding Sept 1 = Sept 11? Let's recalc carefully. If "triggering day is excluded", deadline is 10 calendar days after award notice. Example if event Monday, 10-day period ends Thursday of next? Let's count.

Sept 1 is Wed day 0.
Sept 2 Thu day 1
Sept 3 Fri day 2
Sept 4 Sat day 3
Sept 5 Sun day 4
Sept 6 Mon day 5
Sept 7 Tue day 6
Sept 8 Wed day 7
Sept 9 Thu day 8
Sept 10 Fri day 9
Sept 11 Sat day 10
So 10 days after award notice (excluding day 0) ends Sept 11. If Board closed? open relevant. So later of (a) and (b).

Required debriefing Sat Sept 4. Exclude Sep 4. Five calendar days after:
Sept 5 Sun day 1
Sept 6 Mon day 2
Sept 7 Tue day 3
Sept 8 Wed day 4
Sept 9 Thu day 5
So 5 days after debriefing ends Sept 9. The later of Sept 11 and Sept 9 is Sept 11. Wait rule says "later of: (a) ten days after award notice; or (b) five days after required debriefing." Later date = Sept 11. So automatic stay if Board receives protest by Sept 11? But note deadline falls Saturday; Board open every relevant date, no extension? It says Board open on every date relevant here; if deadline falls on day Board is closed, filing due next open day. Not relevant. So must receive by Sept 11? Hmm but if Board open Saturday? "Board is open on every date relevant here" says yes. So last filing date that preserves automatic stay is Saturday, September 11, 2027. Need check if "by later of" includes filing on that day; yes "by" deadline. If filing after close? The Board open; need by end of day Sept 11. But maybe "ten calendar days after award notice" and "five calendar days after debriefing" can have nuances if counting "calendar days after" excluding start. Let's verify. If award notice issued Wed Sept 1, "within 10 days after" usually period begins next day and ends at 11:59 p.m. on 10th day, which is Sept 11. Debrief Sat Sept 4, within 5 days ends Sept 9. Later is Sept 11. So last automatic stay is Sept 11.

Need mention merits deadline later: Sept 14. There is tension: to preserve automatic stay, file by Sept 11; merits deadline Sept 14. If file by Sept 11, both timely and automatic stay. If agency-first plan proposes filing agency protest Sept 10, wait for agency answer before going to Board. Under Rule 6: agency-level protest does not trigger Board automatic stay and does not toll either Board deadline unless agency issues written suspension before Board deadline expires. No written commitment. Thus if they wait for agency answer before Board, automatic stay deadline Sept 11 will pass unless the agency issues written suspension before then (or maybe by Sept 11? Actually "before Board deadline expires" maybe if agency issues written suspension before deadline expires; the Board deadline expires Sept 11? It says unless agency issues a written suspension before Board deadline expires. No written suspension here; management says waits for answer. Even if agency answers after Sept 10? no. If file agency protest Sept 10, one day before automatic stay deadline, and no suspension, cannot preserve stay. If they file Board protest Sept 10 too, agency protest maybe unnecessary/risky. Need perhaps say agency-level protest on Sept 10 does not protect; and filing agency protest first could still be followed by Board protest before Sept 11, if they don't wait. But proposed sequence "first filing agency protest on Sept 10 and waiting for agency's answer before going to Board" loses automatic stay because no Board protest by Sept 11; Board merits deadline maybe also could pass if wait beyond Sept 14? It likely will because agency answer later. Need state.

Need "grounds to include in initial Board protest." Include all post-award grounds first disclosed at debriefing (not waived):
- Agency's evaluation of Atlas's sensor-resolution score: credited based on a model not identified in proposal. Legal? Procurement must evaluate proposals based on criteria and information in proposal? Unstated evaluation criterion/unequal treatment? Maybe "the agency evaluated Atlas on a model not identified in its proposal" = violates evaluation as stated, lacks transparency, possibly best-value judgment not based on proposal? Need include supporting facts then known: Atlas did not identify model in proposal; agency credited a score.
- Subcontractor experience: solicitation clause says relevant subcontractor experience will be considered, but agency treated Silverline's subcontractor experience as zero. Ground: failure to evaluate in accordance with solicitation / disparately? Need include facts: Silverline has relevant subcontractor experience; solicitation promised consideration; agency gave zero weight/no consideration.
- Price/technical tradeoff: Atlas evaluated price $1.8M higher; selected based on disputed technical scoring; if technical scoring corrected, best-value decision may be unsupported; need request a reevaluation and new award decision; challenge to best-value tradeoff. Need tie to first two; not an independent waiver maybe.

Also request protected access to procurement records: According to rule 8, initial protest must state each ground, supporting facts then known, requested relief, and any request for protected access to procurement records. If want access, must request in initial protest? Rule says must state "any request for protected access to procurement records." Later supplementation permitted for facts first learned from agency report. Since facts known limited, should request protected access to agency report/proposal evaluation materials (Atlas proposal, evaluation record, source selection document) to substantiate. Need maybe "Board" has protective order? Need include request.

Supplementation: Only for facts first learned from agency report; cannot add new grounds? Need interpret: Rule 8 "Later supplementation is permitted for facts first learned from the agency report." It says protest must state each ground, supporting facts then known, requested relief, and any request. Later supplementation permitted for facts first learned from agency report. So initial Board protest must include all known grounds; after agency report, can supplement with facts first learned from report to support grounds. You cannot wait to raise new grounds after report if basis known earlier? Need plan: Include all three grounds now, request records, then supplement after agency produces report with specific evidence. Also perhaps if agency report reveals different grounds, maybe supplementation? But phrasing permits supplementation for facts first learned from agency report, not necessarily new legal grounds? Need be careful: "Later supplementation is permitted for facts first learned from the agency report." Could mean you may supplement statement with facts first learned from report, perhaps within existing grounds; if a new ground is first learned from report, maybe also okay? But it says "facts" not "grounds"; best practice raise all known grounds and preserve ability to supplement. Need state no need to wait to learn facts; request file.

Court relief if automatic stay lost:
- No automatic stay in court; Board merits protest timely filed after automatic stay deadline may proceed, performance continues unless Board/court grants discretionary relief.
- Court may issue injunction based on likely success, irreparable harm, balance of harms, public interest. Need if lost automatic stay, file complaint? likely file in federal court? The rules mention court may issue injunction; likely "court relief if automatic stay lost" ask. Need plan: Seek preliminary injunction (or temporary restraining order) to enjoin contract performance/transition. Need show likely success on merits (timely Board protest raising strong grounds, agency's evaluation contrary to solicitation), irreparable harm (proposal costs alone do not establish irreparable harm; transition will make meaningful corrective competition harder, but need more; perhaps loss of opportunity to compete, lost goodwill, competitive harm, inability to obtain meaningful corrective relief; if transition/performance proceeds, corrective competition impossible; procurement law treats lost opportunity and loss of fair chance as irreparable? Need be careful: facts say proposal costs alone do not establish; transition will make meaningful corrective competition harder. Need articulate with evidence. Balance harms: government/Atlas harm vs public interest in lawful procurement/competition; maybe injunction preserves status quo; public interest favors fair procurement. Need mention bond? maybe not required.
- Board can also grant discretionary relief maybe "Board or court" under rule 5; but facts: Board may? Need mention request for "bid/protest bond"? Hmm not necessary. If lost automatic stay, promptly after discovering, seek Board suspension? Actually Rule 5 says Board or court may grant discretionary relief. An agency? Board could grant stay? "performance continues unless Board or court grants discretionary relief." So if auto stay lost, file motion with Board for discretionary stay and/or court injunction. But likely court relief.

Need "exact filing sequence Silverline should use to preserve strongest procedural position." Need craft:
- Do not file agency protest first and wait. Because agency-level protest does not toll/stay and no suspension. Need file Board protest no later than September 11 to preserve automatic stay; if possible today or by Sept 10. The "strongest procedural position" is:
  1. Today Sept 7 (or immediately): Prepare and file Board protest, including all three post-award grounds, facts known, requested relief, and request for protected access. If by Sept 11, automatic stay triggered. Earliest is best; filing by Sept 11. Could file before agency protest.
  2. Consider also filing agency-level protest? Do we need? Maybe no; the prompt asks why proposed agency-first does/doesn't protect stay and exact sequence. Should we include perhaps no agency-level protest because it wastes time and no tolling; but maybe one can file agency protest simultaneously or after Board protest? Need evaluate strategic value. Agency protest may be used to allow agency to correct? But if Board automatic stay by Sept 11, filing agency protest not needed for stay. Might complicate? Rule 6 says agency protest doesn't trigger stay/toll. If file Board protest by Sept 11, automatic stay in effect; then agency-level protest is optional? Could have procedural benefit (agency report? no, Board report). But "exact filing sequence" should be to preserve strongest procedural position: file Board protest first by Sept 11. If management insists on agency protest, file agency protest only after Board protest? Need think.

Maybe to preserve strongest procedural position, file the Board protest by Sept 10 (before proposed agency protest? Wait date: Today Sept 7. Proposal agency protest Sept 10. Need Board by Sept 11. Could file agency Sept 10 and Board Sept 10? But if waiting for agency's answer, no. Exact sequence could be:
- Immediately (Sept 7): File Board protest (or at latest Sept 10) to preserve automatic stay. 
- Do not wait for agency answer.
- Optional: If agency-level protest is desired for settlement/agency corrective action, file it at same time or after Board protest, but not instead; do not rely on it. But "exact" maybe "file Board protest first, no agency protest before it." Need decide.

Let's read prompt carefully: "Management proposes first filing an agency protest on September 10 and waiting for the agency's answer before going to the Board. The agency has made no written commitment to suspend performance." Assignment includes:
- Why the proposed agency-first sequence does or does not protect the stay.
- The exact filing sequence Silverline should use to preserve the strongest procedural position.

The answer should say proposed agency-first fails; to preserve auto stay, must file Board protest by Sept 11. The exact sequence: file Board protest before agency protest; no later than Sept 11, likely now/Sept 10 at latest. Include all grounds and protected access request. If they want agency protest, file it after Board protest? Is there any downside? Filing agency-level protest after Board could be permitted? Under rules, agency-level protest maybe an alternative? It might be optional. But if Board protest filed, automatic stay applies; then agency protest maybe to seek voluntary agency corrective action? But the Board protest remains. Not necessary. Could say "No agency-level protest is necessary; if used, file it only after the Board protest and never wait for agency answer."

Need perhaps compute "last filing date that preserves automatic stay": Sept 11, 2027. But wait, if Board open on every date relevant, including Saturday Sept 11, yes. Need maybe if "filing due next open day" but Board open, so no extension. Need perhaps "Saturday" not "Friday" if confusion. Let's check Sept 2027 calendar: Need verify weekday names? User says award notice Wednesday, September 1, 2027. Is Sept 1 2027 actually Wednesday? Let's confirm mentally: 2027 Jan 1 Friday? 2024 Jan1 Monday, 2025 Wed, 2026 Thu, 2027 Friday. 2027 Sep 1? Jan 1 Friday. Day of year Sept 1 = 244? Jan31+Feb28+Mar31+Apr30+May31+Jun30+Jul31+Aug31 = 243 days before Sep1? Jan-Aug: 31+28+31+30+31+30+31+31 = 243, Sep1 day 244. Jan 1 Friday; Jan 1 day 1 Friday; day 244? (244-1 mod7=243 mod7=5; Friday+5 = Wednesday? Friday+5 = Wednesday? Let's list Fri=0, Sat1, Sun2, Mon3, Tue4, Wed5. Yes Wednesday. Debrief Sat Sept 4. Today Tuesday Sep 7. Correct.

Now, let's think deeply about legal nuances from "Governing law." We need answer not too overlong but covers all. Desired oververbosity 5, but user asks detailed plan, so moderate. Need perhaps use headings.

Potential issues:

1. Waived solicitation ground:
- The "polar-region experience" requirement was open/obvious before bid deadline. Silverline submitted with only 3 years. Rule 1: an apparent solicitation defect must be filed before bid deadline; failure waives ground. It is not revived by debriefing. Therefore cannot be a basis in Board protest or court. It might be mentioned as context? Better not as ground; can mention in corrective relief? No, waived. Need answer: exclude from initial protest; don't argue unnecessarily restrictive. It may support maybe no? No.

2. Date knew post-award grounds:
- Saturday Sept 4, 2027, required debriefing where disclosed; written slides same day. Because required debriefing delays knowledge for matters first disclosed there. So day of knowledge is Sept 4. If the grounds were known earlier? Facts say "For the first time, Authority disclosed" at debriefing. So Sept 4. Maybe "knew or should have known" on Sept 4. If debriefing was required, Rule 3 delays; thus not earlier. Need maybe "the day of knowledge is excluded" for deadline.

3. Ten-calendar-day Board merits deadline:
- Start Sept 5, count 10: Sept 14, 2027. Wait? Let's recalc one more time. If known Sept 4 and day excluded, ten days "after" could be Sept 14? Let's use examples: Under FAR? If decision has date of receipt, timely protest filed within 10 days "after" the basis is known; "the day of knowledge is excluded." If knowledge on Monday, due 10 days later Thursday? Actually if Monday day 0, Tuesday day 1, Wednesday 2, Thursday 3, Friday 4, Saturday 5, Sunday 6, Monday 7, Tuesday 8, Wednesday 9, Thursday 10. Yes. So Sept 4 Sat day 0, Sept 14 Tue day 10. Good. "Ten-calendar-day Board merits deadline" (for post-award to Board) is Sept 14, assuming Board open. If not, next open; Board open all relevant. Need perhaps mention "although a Board protest filed after Sept 11 but on/before Sept 14 would be timely on the merits, it would not get automatic stay."

4. Two alternative automatic-stay calculations and which date controls:
- Calculation (a): 10 days after award notice, excluding Sept 1 = Sept 11.
- Calculation (b): 5 days after required debriefing, excluding Sept 4 = Sept 9.
- Automatic stay deadline: later = Sept 11. (Not Sept 14). Need maybe "The longer 10-day post-award date controls." This is a bit counterintuitive because "later of" in rule 4: (a) ten days after award notice; (b) five days after required debriefing. Since (a) later. Good.

5. Last filing date preserves automatic stay:
- September 11, 2027 (Saturday), by end of day, at Board. If Board open; "by" Sept 11. Need perhaps "not Sept 14." If they file Sept 14, merits timely but no automatic stay.

6. Agency-first sequence:
- Proposed agency protest Sept 10. Agency-level protest no automatic stay and no tolling unless agency issues written suspension before Board deadline (Sept 11) expires. There is no written suspension; waiting for agency answer before going to Board would allow Sept 11 to pass, so automatic stay lost. Even if Sept 10 agency protest somehow results in answer before Sept 11? Facts say no commitment; no. Need "unless the agency issues a written suspension before the Board deadline expires" maybe could be issued after agency protest? But no. It is not enough to file agency protest. If the agency somehow issues a written suspension before Sept 11, maybe it suspends? Wait Rule 6: "An agency-level protest does not trigger the Board's automatic stay and does not toll either Board deadline unless the agency issues a written suspension before the Board deadline expires." If the agency issues a written suspension before Board deadline expires, perhaps then it does toll? Or "unless" modifies both? Need parse. It says agency-level protest does not trigger automatic stay and does not toll either Board deadline unless agency issues written suspension before the Board deadline expires. Thus if agency issues written suspension before Sept 11, perhaps Board deadlines tolled or stay? But no commitment; management plan relies on waiting, not on suspension. Could mention "Only a written suspension issued before the deadline would change this; none exists." Maybe if agency has not made written commitment, no suspension. The agency protest itself not enough. Good.
- Also, if they wait for agency answer and don't file Board until after Sept 14, they may lose merits too; but prompt says Board deadlines. Need mention.

7. Grounds to include in initial Board protest:
Need detail. Let's craft as:
   a. Evaluation of Atlas was not based on the proposal. It credited a sensor-resolution score using a model Atlas did not identify in its proposal. This appears to rely on an unstated evaluation criterion or outside information, inconsistent with the solicitation and evaluation terms.
   b. The agency failed to give Silverline's subcontractor experience any consideration, despite solicitation clause that relevant subcontractor experience "will be considered." This is a violation of the solicitation's evaluation scheme/arbitrary and capricious evaluation.
   c. The best-value tradeoff is therefore unsupported: Atlas's evaluated price is $1.8M higher; the award decision rests on the challenged technical scoring; if corrected, the source-selection decision cannot stand.
Need maybe include request for relief: set aside award; require reevaluation and new source-selection decision; enjoin performance during Board consideration; award costs; protect records. Rule 8 says "state each ground, supporting facts then known, requested relief, and any request for protected access." We need explicitly include requested relief. Good.

8. Role of protected-record access and supplementation:
- Initial Board protest must request protected access to procurement records. Without request, may waive? Rule says "must state ... any request." Need include request to "all evaluation records, Atlas proposal, source-selection document, technical evaluation models/scores, price/technical tradeoff, subcontractor experience evaluation." Request expedited protective order. This supports merits.
- After agency report, Silverline may supplement with facts first learned from the agency report. It cannot rely on new facts? Need phrase: "Supplementation is not a substitute for stating known grounds; use the report to substantiate and expand grounds, not to raise waived/known matters." If the agency report reveals a new ground? Since rule says "facts first learned," you might preserve by including a reservation? But must state each ground. Need maybe "If the agency report reveals a basis not previously known, the supplementation provision should be invoked promptly; however, do not count on it for anything known now." But prompt says "Later supplementation is permitted for facts first learned from the agency report." So yes, state that. But need be careful: It might not allow "new grounds" but facts. We can say "because the grounds are already pleaded, supplementation will provide the evidentiary detail."

9. Court relief if automatic stay lost:
- File suit in court and move for preliminary injunction/TRO before transition/performance. Need show:
   * Likely success on merits (at least serious/likely because Board protest timely and grounds allege solicitation deviation; but not based on waived polar requirement).
   * Irreparable harm: need assert more than proposal costs; loss of fair opportunity to compete and inability to obtain meaningful corrective relief because transition will begin Sept 13; performance of a tainted award may be difficult to undo; proposal costs alone insufficient. Maybe "meaningful corrective competition harder" is evidence of harm; but court may require more. Need perhaps cite balance of harms/public interest: injunction preserves status quo; public interest favors procurement integrity, competition, and compliance with solicitation.
   * If automatic stay lost, Board could grant discretionary stay as alternative; ask Board for interim relief immediately if possible, but court injunctive relief is the direct route. Need mention "court filing creates no automatic stay" so must seek injunction.
- Could a court grant injunction if Board merits protest still pending; yes likely. Need perhaps "Exhaustion? Not specified; rules allow court." We shouldn't introduce not in facts. "Board or court" says Board or court. Court may issue injunction. Need phrase "If the award has already begun, seek a temporary restraining order on an expedited basis before Sept 13 transition work."
- Also "if automatic stay is lost" may be due to failure to file by Sept 11; if we follow plan, no lost. But if it happens, court relief.

10. Exact filing sequence:
Need synthesize:
- Step 1: Immediately (today Sept 7 or before end of day Sept 10; actually for automatic stay no later than Sept 11 but to be strongest, today/Sept 7) file the Board protest.
- Step 2: Include all three grounds; request protected access; request stay/automatic stay, specify award/performance not to proceed; preserve merits deadline.
- Step 3: Do not file agency protest first; do not wait for agency answer. If agency-level protest is desired, file after Board protest (e.g., same day/Sept 10) but no reliance. Actually "exact sequence" maybe "Board protest first, at latest by Sept 10" and "agency protest unnecessary." Need maybe include "If Management insists on agency protest, do it only after the Board filing and with a statement that it does not replace the Board protest; otherwise omit it entirely." Need decide if to include agency after Board. The user asks exact sequence; we can say:
   1. By close of business Sept 7 (or no later than Sept 10): File Board protest. This starts automatic stay because Sept 11 deadline; it is also within merits deadline.
   2. Concurrently/after Board filing: file a request for protected access (or included). 
   3. Optional agency protest if desired after Board filing; but not before and not instead.
   4. If agency answers and proposes corrective action, coordinate with Board; continue to pursue Board protest unless resolved with relief.
   5. If agency issues report, supplement.
Maybe exact "Sept 10" agency protest proposal? If they file Board Sept 10 (same date) that's okay because before Sept 11; but what if Board filing on Sept 10 after agency protest? If same day, automatic stay preserved if Board receives by end of day Sept 11. But "waiting for agency answer" no. Maybe "do not wait until Sept 10; file today/Sept 7." But if they want to meet proposed agency Sept 10, they could file Board on Sept 10 and still before stay deadline. But "strongest procedural position" means file Board as soon as possible; Sept 7. Need mention "same-day is enough, but earlier is safer and gives time to correct defects."

Need perhaps discuss "timely filing preserves automatic stay" if Board receives protest by Sept 11; if file on Sept 11, automatic stay. But "the later of" is Sept 11; if file on Sept 11, okay. But if Board is open Saturday. Maybe "the Board is open on every relevant date, so no Monday extension." Good.

Need perhaps discuss "waived solicitation ground" in context of court? Since if Board protest includes waived ground, it could undermine credibility; omit. If they mention polar experience in factual background, phrase not as ground. Need "do not make it the basis of relief."

Need maybe mention "Atlas's evaluated price was higher" as ground? Under procurement, an agency can select higher-priced proposal if best value and technical superiority; not inherently illegal. Need frame as "disputed technical scoring is the only basis; price premium cannot be justified by arbitrary/unsupported technical evaluation." Good.

Let's examine rule details:
Rule 1: "A protest based on an apparent solicitation defect must be filed before the bid deadline. A bidder that submits without timely protesting an obvious term waives that ground." So yes.

Rule 2: "A post-award protest to the Procurement Review Board must be filed within ten calendar days after the protester knew or should have known the basis. The day of knowledge is excluded."
Potential issue: The Board merits deadline may be ten days after "knew or should have known the basis." The post-award grounds were disclosed at debriefing Sept 4. But "Atlas's evaluated price was $1.8 million higher" was maybe in award notice? The debriefing disclosed? Facts says debriefing disclosed price? It says "It credited Atlas... It treated Silverline... Atlas's evaluated price was $1.8 million higher, but the Authority selected it based on disputed technical scoring." It may be first disclosed in debriefing? Not explicitly "for the first time" for all? The intro says "For the first time, the Authority disclosed that: * It credited ... * It treated ... * Atlas's evaluated price was..." Yes yes. So known Sept 4. Good.

Required debriefing: If a required debriefing delays knowledge of matters first disclosed there. It does not revive apparent solicitation defect. Need no issue.

Rule 4: "Award performance is automatically stayed only if the Board receives the protest by the later of: (a) ten calendar days after award notice; or (b) five calendar days after the required debriefing. The triggering day is excluded."
Need maybe "award notice" (Sept 1) vs "award" date? It says award notice selected Atlas. We use Sept 1. If "after award notice" maybe day after award notice. OK.
Could "automatically stayed only if Board receives protest by later of (a) or (b)" means if filing after later deadline, no stay even if within merits. Yes. Filing before later = automatic stay.
Need maybe "filing date" if Board receives by mail? "receives" means actual receipt; use hand-delivery/electronic filing if available to ensure by deadline. Need mention "do not rely on mailing; use a filing method with proof of receipt." Good practical.

Rule 6: "An agency-level protest does not trigger the Board's automatic stay and does not toll either Board deadline unless the agency issues a written suspension before the Board deadline expires." Need if agency has no written commitment to suspend; so no.

Potential tricky nuance: If agency-level protest filed Sept 10, does automatic-stay deadline become Sept 11? It doesn't toll; yes. If agency issues written suspension before Board deadline expires, maybe "either Board deadline" would be tolled? Not relevant. Mention.

Potential issue: "Board open on every date relevant here" means Sept 11 Saturday is open; no extension. But in normal federal procurement, weekends? But "Board open on every date relevant here" explicitly. Need mention to avoid saying deadline Monday Sept 13 due to weekend. Good.

Need maybe mention "Calendar days include weekends; all dates count; no extension." Good.

Need maybe consider "award notice Wednesday, September 1, 2027. The notice selected Atlas Meridian..." "Debriefing Saturday, September 4." "Atlas scheduled to begin transition work September 13." If Board receives protest on Sept 11, automatic stay starts? It says award performance automatically stayed only if Board receives protest by later date. Does "automatic stay" apply immediately upon filing, even if performance starts Sept 13? Yes if Board receives by Sept 11, stay is in effect, so Atlas cannot begin transition Sept 13 unless lifted. Need mention.

Need perhaps compute "agency-first sequence": If they file agency protest Sept 10 and wait for agency's answer, by the time agency answers probably after Sept 11 and maybe after merits Sept 14, Board protest might be untimely. Rule 6 no toll; so dangerous. Need say "it does not protect the stay and risks total loss of protest rights." Good.

Need perhaps include "The initial Board protest should not include a request for protected access only after agency report because Rule 8 requires initial request; failure may preclude access." Good.

Need maybe address "later supplementation is permitted for facts first learned from agency report" with "this means you should file your protest now even while lacking full record; after agency report, you can supplement." Good.

Need maybe mention "Board may issue protective order and provide access to proprietary/confidential records; use the supplementation later." Good.

Potential issue with "protected access" and "procurement records": "The protest must state each ground, supporting facts then known, requested relief, and any request for protected access." The proposed plan should include "request protected access to all procurement records, including..." and "if the rules require a separate protective order application, file it contemporaneously." Good.

Need maybe think about "ordered protest plan" maybe numbered list. We should structure answer with bullets matching assignment. Need maybe include concise computations.

Potential "court relief if automatic stay is lost" nuance:
- "Filing in court creates no automatic stay." So if auto stay lost, file a complaint and motion for preliminary injunction/TRO; ask court to expedite. Need "likely success on merits" maybe because Board protest was timely? Wait if auto stay lost but Board merits protest filed by Sept 14, it may proceed. If Board protest wasn't filed until after Sept 14, court likely no? But if court considers "likely success" maybe Board protest pending. Need state "if the Board protest is still timely" but after automatic stay lost? We can say "Assuming the Board protest was still timely on the merits (filed by Sept 14), the court can consider the likelihood of success based on that protest." If it missed Board deadline, court may be barred; but the facts ask "if auto stay is lost" perhaps by filing after Sept 11 but before Sept 14. Need avoid discussing exhaustion not in rules. 
- Irreparable harm: Need perhaps quote "proposal costs alone do not establish irreparable harm." Need say "rely on loss of the opportunity to compete fairly, loss of the chance to receive award, and the erosion of meaningful corrective competition caused by transition/performance; these are the irreparable consequences, not merely bid preparation costs." Is "loss of chance" in procurement often irreparable? Yes.
- Balance/public interest: "public interest favors honest, competitive procurement and enforcing solicitation terms; a bond can protect Atlas, but no performance yet? Transition starts Sept 13; if start before Board decision, corrective relief will be impaired." Good.

Potential "exact filing sequence" maybe should include "File by Saturday, September 11; if at all possible before close on Sept 10 because if any filing defect, you have Sept 11? Hmm same? Actually if filing Sept 11 and there's a filing defect? Board open; no time to correct. Strongest procedural position is file as soon as possible (Sept 7 or 8), not wait. Need mention "no later than Sept 10 to create a buffer while still satisfying automatic-stay deadline; but legally Sept 11 is deadline." But "exact" maybe "today (Tuesday, Sept 7), file." Need perhaps phrase: "Best practice: file now. The hard deadline is Sept 11, but do not wait."
Need maybe discuss "agency protest on Sept 10" if also Board protest same day? Strongest? no need. But if management wants agency, file agency protest after Board protest. Need perhaps "Do not file agency protest on Sept 10 before the Board protest; if both are to be filed, file Board protest first (ideally before Sept 10) and then agency protest, while treating Board protest as primary." Need consider whether filing agency protest after Board protest could "wait for agency answer" no; it is optional. Could it have any negative effect? Maybe agency protest may "toll" only if written suspension; not. It may cause agency to withhold corrective action? But if Board protest is already filed, agency can still take corrective action? Under many systems, agency has discretion to reconsider? Not specified. But the prompt asks "Management proposes..." We can say "Do not adopt agency-first." Good.

Need perhaps "Do not mention waived solicitation defect in the Board protest or court filings except, if necessary, as background explaining why Silverline lacked polar experience? But that could show it was on notice. No need." Need maybe "The five-year requirement cannot be challenged now; it cannot be supplemented later." Good.

Potential "supporting facts then known" in initial protest: Need specify facts:
- Atlas proposal not identify the model used for sensor-resolution score. Maybe "On information and belief, no model was identified; agency credited score based on unidentifiable model." But Rule 8 requires facts "then known." We know from debriefing. Use "At debriefing, Authority said it credited Atlas with score based on a model not identified in Atlas's proposal." Good.
- Subcontractor experience: solicitation clause relevant subcontractor experience "will be considered"; Silverline submitted subcontractor experience; agency scored as zero. Need maybe "contract clause" if known; yes.
- Price/technical: Atlas evaluated price $1.8M higher; if technical score corrected, price premium not justified. Good.

Potential "waived solicitation ground" maybe "unnecessarily restrictive" could not be raised via debriefing as an apparent defect. Rule 3 "does not revive an apparent solicitation defect." Need maybe "The debriefing's disclosure of technical evaluations does not make the restriction newly a post-award ground; the defect was apparent before bid." Need include.

Potential "automatic stay deadline and merits deadline: which controls?" There are two deadlines. If they file after Sept 11 but by Sept 14, Board may proceed but performance continues. If after Sept 14, protest dismissed as untimely (unless exception? no). Need maybe include "The agency protest on Sept 10 doesn't affect either deadline." Good.

Potential "Board is open on every date relevant here" means "no deadline extension based on closure; if Sept 11 is Saturday, Board open." Need include "The usual next-business-day extension is not triggered."

Potential "triggering day excluded": For automatic stay, there are two triggering days: award notice and debriefing. Need show counts:
- Award: Sept 1 = day 0; Sept 11 = day 10.
- Debriefing: Sept 4 = day 0; Sept 9 = day 5.
Use maybe "later of" -> Sept 11.

Let's double-check date arithmetic for merits and automatic with "within ten calendar days after knew" if day of knowledge excluded:
Knowledge Sept 4; day 1 Sept 5; day 10 Sept 14. If the Board is open all dates. If a deadline falls on Sunday? Sept 11 Saturday; no closing. If Board closed Saturday? They said open. Good.

Potential "award notice" date count:
Ten days after award notice: If award notice was Wednesday Sept 1, "within ten days after award notice" excludes day of notification. If one includes "after" not "from", the first day is Sept 2. Ten days later Sept 11. Good.
Alternative calculation "later of (a) ten days after award notice; or (b) five days after debriefing: (a) Sept 11, (b) Sept 9, later Sept 11." Good.

Potential "The triggering day is excluded" for award notice and debriefing. Need maybe "This yields deadline dates, not 'by September 12 at midnight'." Fine.

Potential "the date Silverline knew post-award grounds" could be "Saturday Sept 4, not Monday Sept 6 because debriefing held Saturday and received written slides same day." The prompt says required debriefing on Saturday Sept 4; "For the first time, Authority disclosed..." If a "required debriefing" occurs Saturday, does "knew" on Saturday even if Board closed? yes. Day excluded. Good.

Potential "post-award protest to Board must be filed within ten calendar days after knew or should have known. Day of knowledge excluded." Since today Sept 7, days remaining: file by Sept 14. Today is day 3? Count Sept5 1, 6 2, 7 3. Need perhaps mention "As of Tuesday Sept 7, there are seven calendar days left under merits deadline; but for automatic stay, only four days remain" (Sept 8,9,10,11). Actually if today Sept 7, deadline Sept 14; left including today? Sept7 day3, Sept14 day10; remaining days after today: Sept 8-14 = 7; today if not filed, 8? Let's not need. But maybe "only until Sept 11 for stay." Need if "Management proposes first filing agency protest on Sept 10 and waiting..." By Sept 10, only one day left to preserve automatic stay. Need mention. Use precise "The automatic-stay deadline is only four calendar days from today? Today Sept7 to Sept11 inclusive = 4 days? Sept7 to Sept11 = 4 days difference; if exclude today, remaining days Sept8,9,10,11 = 4. Good but not necessary.

Potential nuance: "A required debriefing delays knowledge of matters first disclosed there." It doesn't necessarily delay the automatic-stay deadline? Rule 4 separately uses required debriefing. Good.

Potential "Board receives protest" vs "file" maybe if mailed, receipt date. Need maybe "file by a method that ensures receipt by Board by Sept 11; if e-filing/hand-delivery available, use it." Good.

Potential "agency-level protest does not toll either Board deadline" Actually if an agency-level protest is filed before bid deadline? No, here after award. Rule 6 says no unless written suspension. Need maybe "An agency protest filed September 10 does not extend Board merits deadline (Sept 14) or automatic stay deadline (Sept 11)." Good.

Potential "What should initial Board protest include re protected access?" Need maybe "Request protected access under the Board's protective order to the agency report, Atlas proposal, evaluation documents, and source-selection documents. The initial protest must request this; if not, access may be denied. After receiving the report, supplement with facts." Good.

Potential "Later supplementation is permitted for facts first learned from agency report" maybe "not an opportunity to add a ground known before the report." Need include maybe "Do not save grounds for later. If the report reveals new information supporting already-stated grounds, supplement promptly." Good.

Potential "Court relief if automatic stay is lost":
Need maybe consider "The Board may grant discretionary relief" as alternative: "file a motion with the Board for a discretionary stay at the same time as court injunction? Rule 5 says Board or court may grant discretionary relief. But court may be faster because Board may not have injunctive authority? Actually rule says Board or court. Need mention both. "Ask the Board for discretionary relief; if it will not act before Sept 13, file in court for TRO/PI." But user specifically asks "Court relief if automatic stay is lost." We'll focus court but mention Board discretionary. Need maybe "Board's automatic stay lost is not fatal if court issues injunction." Good.

Potential "Filing in court creates no automatic stay" - need mention "must move for injunction; filing alone won't stop performance." Good.

Potential "balance of harms" maybe "Atlas's financial harm from delayed transition may be compensable and/or a bond can protect; Silverline's harm from irrevocable award performance is not." Good.

Potential "public interest" maybe "public interest in lawful competition/agency compliance; not merely in expediting contract." Good.

Potential "exact filing sequence" should perhaps include "No protective access motion? The rule says initial protest must "state any request" maybe included in protest; no separate motion unless Board rules require. Need "file with protest and, if Board requires, a separate motion for protective order." Good.

Potential "requested relief" in initial protest:
- "Stay award/performance pending resolution (automatic if timely; expressly request Board to maintain it)."
- "Require agency to produce complete procurement record."
- "Reserve right to supplement."
- "If violation found, set aside award, reevaluate proposals in accordance with solicitation, make new award decision."
- "Award protest costs and attorney fees? maybe not under rules but include if available." Need maybe not include fees because not specified. But "requested relief" perhaps enough.

Need maybe discuss "state each ground, supporting facts then known" - If facts not fully known, need "on information and belief" when necessary. E.g., "Atlas proposal did not identify a model" is a fact from debriefing; "agency credited based on model" etc. Good.

Potential "grounds to include in initial Board protest" maybe "Do not include 'unnecessarily restrictive polar requirement' but can include 'agency failed to consider subcontractor experience' (which is distinct from facial solicitation defect) because the clause said will be considered; the alleged violation is the agency's failure to apply the solicitation's evaluation scheme, not an attack on an obvious term." This distinction important; need maybe explicitly "The subcontractor-experience ground is not waived because it does not challenge the solicitation's five-year experience requirement; it challenges the agency's failure to evaluate a subcontr experience clause that appears in the solicitation." Wait if the solicitation "openly required five years of polar-region experience" and Silverline had only three but subcontractor experience might be relevant? The ground: "It treated Silverline's subcontractor experience as worth zero despite a solicitation clause stating subcontractor experience 'will be considered'." This is not necessarily an "apparent solicitation defect" because the solicitation contains a favorable clause; maybe it's post-award evaluation error. Need ensure we distinguish. Could an "apparent solicitation defect" include failure to state how subcontractor experience is weighted? No, not argued. So okay. Need say "This ground is not a waiver problem because it is not a pre-bid challenge to the terms; it is an evaluation error first revealed at debriefing."
Potential "sensor-resolution score based on model not identified in proposal" similarly post-award evaluation ground; not apparent solicitation defect? Could Silverline have known solicitation did not specify model? Maybe if solicitation's evaluation criterion is vague, apparent defect? But the fact that agency used a model not in proposal is not apparent until debriefing. Good.

Potential "The waived solicitation ground" maybe if Board/court considers "unnecessarily restrictive requirement" in collateral context? "It may not be used to show agency had bias or as a basis for relief." Need maybe "It cannot be supplemented later; no." Good.

Potential "The required debriefing delays knowledge ... It does not revive an apparent solicitation defect." Need perhaps "Because the polar experience term was openly stated before bids, the debriefing cannot turn that waiver into a timely protest." Good.

Potential "Automatic stay calculations" need "which date controls" maybe answer "The 10-day award-notice deadline controls because it is later than the 5-day debriefing deadline. So automatic-stay deadline is Sept 11." Good.

Potential "Why agency-first sequence does or does not protect the stay" maybe "It does not. The agency protest on Sept 10 will be too late? Actually agency protest not relevant. The Board automatic stay can still be preserved if they file Board protest by Sept 11 even after filing agency protest on Sept 10, but the 'waiting for answer' part kills it." Need maybe answer "The sequence as proposed does not protect the stay. The only effect of the agency protest is to use a day; no suspension; no tolling; the Board deadline remains Sept 11. If they wait for agency answer, Board protest will not be 'received by Board' by Sept 11, so no automatic stay. It may also miss the merits deadline if the answer comes after Sept 14." Good.

Potential "Does the agency-level protest on Sept 10, if Board protest filed after agency answer but before Sept 14, preserve merits?" No, agency protest doesn't toll; if Board answer by e.g. Sept 20, Board merits deadline is Sept 14, so Board protest untimely. Need mention. The prompt specifically "waiting for agency's answer before going to Board" likely answer after Sept14. So "may also forfeit the merits deadline." Good.
If agency issues written suspension before Sept 11, maybe Board deadline tolled; but no commitment. Need mention "unless and until a written suspension is issued before Sept 11, do not assume." But "agency has made no written commitment." Good.

Potential "what if agency protest itself stops transition? no." Good.

Potential "Court relief if automatic stay is lost" Need maybe "A court injunction can be requested even if Board protest is pending; court determines independently." Good.

Potential "Exact filing sequence" maybe include "If agency-level protest desired, not before Board; because an agency protest creates no stay and the agency has not agreed to suspend; it should be filed only as a supplemental/optional measure after Board protect." Need perhaps "The strongest procedural position may be to skip agency-level protest entirely; it is not required for Board protest or stay. Silverline should spend time on Board filing." Good.

Potential "The protest must state each ground... and any request for protected access" Need "initial Board protest itself should contain a section entitled 'Request for Protected Access and Agency Report'." Good.

Potential "If automatic stay is preserved by filing by Sept 11, Atlas can't begin transition Sept 13 unless Board lifts stay" Need "This is the key practical effect. The Board's receipt starts the stay automatically; no court order needed." Good.

Potential "What if Board closes at 4:30 pm on Sept 11? "Board open" not specify hours; file during normal business and obtain timestamp. Need maybe "do not wait until late Sept 11; file at least by close of business." Good.

Potential "Board merits deadline and automatic-stay deadline both end on Saturdays? Merits Sept14 Tuesday; automatic Sept11 Saturday. Good.

Potential "Calendar days include weekends" maybe if automatic-stay deadline falls Saturday and Board open, due Saturday. If Board were closed, due Monday; not. Good.

Potential "Post-award protest to Board must be filed within ten calendar days after knew or should have known the basis. Day of knowledge excluded." If Board open every relevant date; no extension. Good.

Potential "Award performance automatically stayed only if Board receives protest by the later of (a) ten calendar days after award notice; or (b) five calendar days after required debriefing." Here if a protest is filed by Sept 11, automatic stay, even if filed before debriefing? Already after debriefing. Good.

Potential "Protected record access" maybe "If Silverline does not request access, it may be unable to see the agency report and Atlas confidential info; supplementation after report could be hampered. Include a protective order request." Good.

Potential "Atlas's evaluated price $1.8M higher" ground? Need maybe "Price premium is not necessarily fatal; but if the only rationale is the challenged technical score, then the cost/technical tradeoff is arbitrary. The Board should require a new tradeoff if the technical evaluation cannot be sustained." Good.

Potential "Silverline spent $620,000 preparing its proposal and transition will make corrective competition harder" in court relief. Need "Proposal costs alone insufficient; but here transition/performance threatens meaningful corrective competition. However, this plus loss of fair opportunity is the irreparable harm." Need perhaps "The agency's ability to award to Silverline after corrective action if performance proceeds" is concrete. Good.

Potential "Court injunction standard" maybe "likely success" not "probable success"? We'll state. Need "Four factors: likely success, irreparable harm, balance, public interest." Good.
Potential "TRO vs preliminary injunction" maybe "if transition is imminent (Sept 13), move for TRO immediately and schedule PI; or seek an injunction before Sept 13." Good.
Potential "If court not available before Sept 11?" Not in facts; no need.

Potential "protected access and supplementation" maybe "The agency report will be produced after initial protest; facts first learned in it can be added by amendment/supplement. Do not wait for report to file." Good.

Potential "initial Board protest and automatic stay" maybe "The automatic stay applies when Board receives protest; no motion necessary? But rule says automatically stayed. Need still "request that Board confirm automatic stay; but no additional step required." Good.
Potential "agency-level protest after Board filing" maybe "if the agency then issues written suspension, fine; but if not, Board stay remains." Good.

Potential "Board merits deadline if required debriefing delays knowledge of matters first disclosed there" Could "matters first disclosed there" maybe "Silverline knew or should have known" on Sept 4 but "written debriefing slides same day." No issue.
Potential "Atlas's evaluated price was $1.8M higher" maybe was in award notice? It says award notice selected Atlas; no. We assume first disclosed.

Potential "What does 'award notice' mean in automatic stay? issued to Silverline? "Authority issued award notice to Silverline on Wednesday Sept 1" maybe not public? yes.

Potential "filing by the later of (a) ten days after award notice or (b) five days after required debriefing" If Board receives by Sept 11, even though "ten calendar days after award notice" is Sept 11; no extension. Good.
Potential "The triggering day is excluded" - For "ten calendar days after award notice", if triggering day is day award notice issued? yes.

Potential "The Board open every date relevant here" means no issue with weekends. Need mention "Saturday count included." Good.

Potential "Management proposes first filing an agency protest on September 10" Maybe if agency protest at agency on Sept 10 and Board protest on Sept 10 after, automatic stay still preserved. But "agency-first" maybe before Board, not waiting? The prompt says "and waiting for agency's answer before going to Board." So no.
Potential "If agency issues a written suspension before Board deadline expires" maybe if Silverline asks agency to suspend on Sept 10 and agency does so in writing before Sept 11, it may toll? The rules say unless agency issues written suspension before Board deadline expires. But facts "agency has made no written commitment to suspend performance." Management plans "waiting for agency's answer", not seeking suspension. Need mention "A request for agency answer is not a request for suspension; even a verbal assurance no." Good.

Potential "If the agency issues written suspension, does it trigger automatic stay? No, but it "does not toll unless..." Actually if agency-level protest with written suspension before deadline, maybe agency itself suspends? Rule says no automatic stay/no toll unless written suspension. If written suspension, it might stop performance and toll deadlines perhaps. But not here. Need not dwell.

Potential "Court relief if automatic stay lost" maybe "If no automatic stay due to missed Sept 11, they can still file Board merits protest by Sept 14; after that, if Board denies or before, seek court. But court may be more receptive if Board protest has substantial merit." Good.

Potential "Exact filing sequence" perhaps "Do not let the merits deadline (Sept 14) be the target; the stay deadline is the driving deadline." Good.

Potential "Should they file agency protest before bid? No, bid deadline passed. Not relevant. Need not.

Potential "The grounds to include in initial Board protest" perhaps include "Do not assert 'the solicitation is unnecessarily restrictive' due to waiver." Good.

Let's maybe draft answer in structured outline:

Title: Ordered Protest Plan

1. Waived solicitation ground
- The polar experience requirement must be omitted. It was obvious pre-bid; Silverline submitted; debriefing doesn't revive. Any Board/court ground based on it will be dismissed/waived.

2. Knowledge date and deadlines
- Known post-award grounds: Sept 4, 2027 (debriefing; slides same day). Exclude Sept 4.
- Board merits deadline: Sept 14, 2027 (Sept 5 = day 1; Sept 14 = day 10).
- Automatic stay:
   * Award-notice trigger: Sept 1; exclude; 10th day = Sept 11.
   * Debriefing trigger: Sept 4; exclude; 5th day = Sept 9.
   * Later of those: Sept 11. Since Board open Sept 11, last automatic-stay filing date is Sept 11. If filing after Sept 11 but by Sept 14, protest may be considered but performance continues.

3. Agency-first proposal
- It does not preserve the automatic stay. The Sept 10 agency protest does not start Board stay or toll Board deadlines (Rule 6). Unless a written suspension issued before Sept 11, none. Waiting for agency answer means no Board protest by Sept 11. It may also miss merits deadline if answer after Sept 14. Therefore do not wait.

4. Board protest content
- Include all three grounds:
   1. Unstated/unidentified model for sensor score.
   2. Failure to consider subcontractor experience despite "will be considered."
   3. Unsupported best-value/price tradeoff because higher price justified only by flawed technical score.
- Requested relief: set aside, reevaluation, new decision, stay/order not to proceed, etc.
- Do not include waived polar experience ground.

5. Protected access and supplementation
- Initial protest must state request for protected access to agency report, Atlas proposal, evaluation model/score, source-selection docs, etc.; file protective order request. Supplement after agency report with facts first learned; don't add waived or known-before grounds.

6. Court relief if automatic stay lost
- File court action and move for TRO/PI before Sept 13 transition. Four factors; irreparable harm not just proposal costs; rely on loss of fair opportunity and impairing corrective competition. Public interest favors lawful procurement. Filing alone no stay.

7. Exact sequence
- Step 1: Now or as soon as possible (hard deadline Sept 11), file Board protest; not agency-first.
- Step 2: Include all required content and protective access.
- Step 3: If desired, after Board filing, file agency-level protest; don't wait for answer; treat Board as primary.
- Step 4: By Sept 11 confirm receipt/timestamp; if agency hasn't suspended, don't rely on agency.
- Step 5: After agency report, supplement.
- Step 6: If stay lost/performance begins, seek court injunction.

Need perhaps "ordered protest plan" maybe "The exact filing sequence should be: Board protest by end of day Sept 7; optional agency protest Sept 10? Hmm if "exact" maybe "not Sept 10." We can include "Hard deadline: Sept 11; recommended: Sept 7." In "exact sequence" maybe list "first action: Board protest" not "agency protest." Good.

Let's think if there is any issue with "The Board is open on every date relevant here" and "automatic stay deadline falls Saturday Sept 11"; if Board open Saturday, okay. But "later of" dates may be "ten calendar days after award notice" = Sept 11 at end of day. If the Board is open on Saturday but maybe normal filing hours; "by later of" means before close. Good.

Potential "Ten-calendar-day Board merits deadline" if the day of knowledge is excluded, but if a deadline falls on Sunday, next open day. It falls Tuesday. No issue.

Potential "The date Silverline knew post-award grounds" perhaps "the date the debriefing started (Sept. 4), not the date the Board is open; because receipt of written slides same day." Good.

Potential "Required debriefing delays knowledge of matters first disclosed there" - Here if debriefing held Saturday Sept 4; if Monday Sept 6 Labor Day? Board open every relevant, but calendar days. No need.

Potential "award performance automatically stayed only if Board receives protest by later..." If they file Board protest on Sept 11, automatic stay begins; if Atlas begins transition Sept 13, prohibited. If Board later decides? yes.

Potential "Grounds to include in initial Board protest" need maybe "supporting facts then known" include "The debriefing slides themselves" as an attachment? Could mention "attach debriefing slides." Good. Maybe "the initial protest should incorporate the slide contents by reference" but not necessary. Need include "state facts with specificity, not bare conclusions." Good.

Potential "Later supplementation is permitted for facts first learned from agency report" Could also request "agency report" with protected access. Need mention "do not wait for the agency's answer to agency protest; agency report in Board process is different."
Potential "Agency-level protest" maybe "if filed at all, it should not be the vehicle for litigating grounds. It doesn't create automatic stay." Good.

Potential "Court injunction if automatic stay lost" maybe "The court can also consider if the agency's violation is clear; because Silverline did not file by Sept 11, no automatic stay, but Board can still grant discretionary stay." Need perhaps mention "Board discretionary relief" even if court relief sought:
- "In addition to filing in court, ask the Board to treat its receipt of the merits protest as a request for discretionary suspension/relief (Rule 5)."
Need include maybe under court relief:
   "First, ask the Board for discretionary relief immediately; then, if needed, file court injunction." But if auto stay lost, maybe Board could grant. The prompt says "Court relief if the automatic stay is lost." We can include both. Need not overdo.

Potential "protest must state requested relief" maybe "If no stay, request Board discretionary stay; if Board denies, court." Good.

Potential "Balance of harms" maybe "if Atlas has not begun transition, an injunction preserves status quo; a reasonable performance deadline extension or bond can address delay; Silverline's harm is not compensable." Good.

Potential "Irreparable harm" perhaps "Because 'proposal costs alone do not establish irreparable harm,' Silverline must articulate why the impending transition and eventual performance would make relief impossible; e.g., the agency would no longer be able to meaningfully compare proposals or return the parties to pre-award status; lost opportunity to compete fairly cannot be recovered." Good.

Potential "Likely success" perhaps "The Board protest must show that evaluation contrary to solicitation likely constitutes prejudicial error; if the agency applied an unstated evaluation model and ignored promised subcontractor consideration, likely success." Good.

Potential "Exact filing sequence" perhaps:
- "Do not file the agency protest first, and do not wait. The Board protest is the only filing that can create automatic stay. If you want to file agency protest, file it only after the Board protest, so it cannot jeopardize the Board deadline. Even then, do not await agency response before proceeding before the Board."
Need maybe "By 'before the Board' if Board protest filed first, it automatically stays performance; agency corrective action might be discouraged? Not in rules. But okay.

Potential "What if management proposes agency protest September 10 to preserve agency's ability to correct? If Board protest filed Sept 7, automatic stay may pressure agency. Later agency protest optional." Good.

Potential "Supplementation" maybe "if later supplementation is allowed, the initial protest must be complete enough to withstand dismissal; you cannot rely solely on supplementation to state grounds." Good.

Potential "Protected access" maybe "Initial Board protest must ask for access to procurement records, including agency's report. If the Board issues protective order, outside counsel can review ATLAS confidential/competitive information? Not specified but likely. Need phrase "request protected access under the Board's protective-order process." Good.

Potential "Court relief if automatic stay is lost" maybe "If no stay, transition work can proceed until court orders otherwise. Move for TRO no later than Sept 10? Wait if auto stay lost because Board not filed by Sept 11, then at Sept12/13? If Board filing was late, maybe court available. If management waits after answer, transition starts. Need perhaps "file court complaint and TRO before Sept 13." Good.

Potential "The merits deadline and automatic stay deadline if agency issues written suspension before Board deadline expires" maybe "agency protest can be okay if they simultaneously request written suspension before Sept 11 and obtain it. But not proposed; no commitment. If a written suspension were issued, it could change deadlines, but it doesn't create an automatic stay." Need maybe mention "don't assume." Good.

Potential "No written commitment to suspend performance" - If agency protest with request for suspension, agency may issue "answer" not suspension. No. Good.

Potential "The agency has made no written commitment to suspend performance" maybe "An agency answer is not a written suspension." Good.

Potential "The Board is open on every date relevant here" - If Board open all relevant, no extension due weekend. Need maybe mention "Sept 11, 2027 is a Saturday but the Board is open, so the next-open-day extension does not apply." Good.

Potential "Silverline wants to protest the award. Several filing paths remain available, but only one timely filing preserves automatic stay." This intro maybe "one timely filing" maybe "Board protest by Sept 11." Yes.

Potential "Filing in court creates no automatic stay" - Need mention under court relief. Good.

Let's consider if "agency-level protest does not toll either Board deadline unless agency issues written suspension before the Board deadline expires." The wording "unless the agency issues a written suspension before the Board deadline expires" might mean if an agency-level protest and agency issues written suspension, then the Board deadline is tolled? Actually Rule 6 says "An agency-level protest does not trigger the Board's automatic stay and does not toll either Board deadline unless the agency issues a written suspension before the Board deadline expires." The "unless" could mean if agency issues written suspension before deadline, the Board's automatic stay deadline? Hmm. But no.

Potential "The later of (a) and (b)" if Board receives protest by Sept 11. But if Sept 11 is Saturday and Board open, last filing date preserves automatic stay. If the Board is open every relevant date, no extension. Good.

Potential "Merits deadline after post-award grounds known at debriefing" if no required debriefing? It is required. "Required debriefing delays knowledge of matters first disclosed there." Good.

Potential "Atlas's evaluated price was $1.8M higher" "evaluated price" maybe "higher price" not necessarily "Atlas's price"; yes.

Potential "If Atlas's evaluated price was higher, but selected based on disputed technical scoring" Need perhaps "A price premium is acceptable only if supported by a rational technical superiority; because technical score may be invalid, source selection decision lacks rational basis." Good.

Potential "Requested relief" maybe "protest must state requested relief" The rule says "requested relief" but not exact. Need include maybe "costs" not if unavailable. We'll state.

Potential "protected access request" maybe "do not wait for agency report; if you wait, no automatic stay and no request." Good.

Potential "If automatic stay preserved, Atlas transition on Sept 13 must be stopped automatically; but if Board denies stay later, can seek court? Not asked. No need.

Potential "Board or court grants discretionary relief" in Rule 5: A timely merits protest after automatic-stay deadline may proceed, but performance continues unless Board or court grants discretionary relief. If automatic stay is lost by filing after Sept 11 but before Sept 14, you can ask Board for discretionary stay and court for injunction. Need mention "the Board has authority to grant discretionary relief; ask in the alternative." Good.

Potential "Exact filing sequence should use to preserve the strongest procedural position" We can include "The critical filing is a Board protest, not an agency protest." Good.

Need perhaps formulate as "Ordered Protest Plan" with numbered "1-10" matching assignment. Let's craft final answer with headings.

Let's think of possible "trap": The automatic-stay deadline is the "later of" (a) 10 days after award notice = Sept 11, and (b) five days after required debriefing = Sept 9. But because award notice Sept 1 and debriefing Sept 4, "later of" is Sept 11. However, if Board receives protest by Sept 11, automatic stay. But what about "the triggering day is excluded" and "within 10 calendar days after award notice" perhaps if award notice Sept 1, due by Sept 11. If "ten calendar days after award notice" means deadline "on the tenth day after" = Sept 11. Good.
Potential "required debriefing" is "held Saturday September 4" and "Silverline received written debriefing slides same day. Today Tuesday September 7" There are 4 days from today to stay deadline. Good.

Potential "merits deadline after post-award grounds" if "ten calendar days after the protester knew or should have known the basis. The day of knowledge is excluded." If the known day is Sept 4, deadline Sept 14. But if Board is open every date, no extension. Good.

Potential "The first filing date that preserves stay" maybe "no later than Sept 11, 2027" but "on Sept 10 after agency protest? If Board receives Sept 10, ok. If Board receives Sept 11, ok." Need "last filing date" = Sept 11, not "by Sept 10 to avoid risk." Good.

Potential "protest to Board must state each ground, supporting facts then known, requested relief, and any request for protected access." If initial Board protest filed today, facts then known limited; but because debriefing slides contain grounds, enough. Later supplementation permitted. Good.

Potential "If Board protest includes grounds not in agency protest? no issue." Good.

Potential "An agency-level protest filed on Sept 10" if the Board protest also filed Sept 10, automatic stay; but "agency-first" maybe not if Board later same day. Need phrase "The agency protest cannot be the reason the stay is preserved; only the Board filing by Sept 11 can." Good.

Potential "Atlas scheduled to begin transition work on Sept 13" If Board protest filed by Sept 11, automatic stay should prevent; if not, court TRO before Sept 13. Good.

Potential "proposal costs alone do not establish irreparable harm" Need not overstate. Could mention "The $620,000 in proposal preparation is not enough; focus on lost opportunity and the fact that transition/performance will make corrective competition 'meaningfully harder'." Good.

Potential "court may issue injunction based on likely success, irreparable harm, balance of harms, and public interest" Need maybe "The same facts supporting a merits protest create likely success; a timely Board protest by Sept 11 means automatic stay, but if lost, court can preserve status quo." Good.

Potential "public interest" maybe "The public interest in public confidence in procurement is served by enjoining an award that may have been based on unstated evaluation criteria and failure to follow solicitation." Good.

Potential "exact filing sequence" "File Board protest by Sept 7? We can say "as soon as possible; no later than Sept 11. The strongest position is to file immediately, not on Sept 10." Good.

Potential "Do not file agency protest on Sept 10" - But "if Management insists, do it only after Board; not before." Should I say "do not file agency-level protest at all" or "optional"? Let's think from procurement strategy. The Board protest automatically stays performance; agency-level protest may be useful to seek agency corrective action, but if a Board protest is pending, the agency may have limited ability to take corrective action without Board dismissal? In federal procurement, an agency can take corrective action even after GAO protest, but not always. In this fictional Board, an agency-level protest is not necessary. "Exact filing sequence" should preserve strongest procedural position, so skip agency protest or defer it until after Board. But maybe management wants agency protest; our answer can say "If used, after Board protest, not instead." Need include perhaps "The agency protest is not a means to stay; do not base sequence on it." Good.

Potential "If they file agency protest Sept 10 and Board protest Sept 10, is there any conflict?" Not under rules. But if the agency-level protest causes agency to issue a written suspension after Board protest, okay. But if Board protest already stayed, agency suspension less needed. No conflict. Good.
Potential "Could filing agency protest after Board protest be seen as failure to exhaust administrative remedies before court? Not in rules; agency-level protest not required. Avoid introducing.

Potential "later supplementation is permitted for facts first learned from agency report" maybe "This means you may move to supplement after the agency files its report; you do not need to wait for the agency-level answer." Good.
Potential "protected access request should mention 'without which Silverline cannot meaningfully respond'." Good.

Need perhaps "The last filing date preserving automatic stay" if Board is open every date relevant: "Saturday, September 11, 2027." Could "Board is open on every date relevant" includes Sunday? It says Board open every date relevant, but Sept 11 Saturday is relevant; no closure. Good.

Potential "Date Silverline knew post-award grounds" maybe "September 4, 2027. Although it was Saturday, the debriefing occurred and slides were received; day of knowledge is not shifted." Good.

Potential "The ten-calendar-day Board merits deadline" if day of knowledge excluded and weekends included: "September 14, 2027 (Tuesday)." Good.

Potential "two alternative automatic-stay calculations and which date controls": maybe "ten days after award notice" = Sept 11; "five days after required debriefing" = Sept 9; later = Sept 11. Need perhaps "Which controls? The longer period controls; the award-notice deadline is later." Good.

Potential "Why proposed agency-first sequence does or does not protect the stay": Need maybe "It does not. Filing an agency protest on Sept 10 does not preserve the Board stay; no Board protest by Sept 11; agency answer no. The later Board merits deadline may be missed if waiting past Sept 14." Good.

Potential "The grounds to include in initial Board protest": Need "All three post-award grounds, but not the polar-experience ground. State each ground in separate count." Good.

Potential "The role of protected-record access and supplementation": Need maybe "Initial request for protected access is mandatory; if omitted, access can be denied. Supplement after report." Good.

Potential "Court relief if automatic stay is lost": Need maybe "Court may issue temporary restraining order/preliminary injunction before Sept 13; no automatic stay from filing; standard." Good.

Potential "Exact filing sequence": Need maybe "The Board protest must be received by the Board, not merely sent. Use electronic/hand delivery." Good.

Let's think of "The Board is open on every date relevant here." Does "every date relevant" include "September 11 Saturday" and "September 12 Sunday" maybe no. "Every date relevant here" perhaps says that no closure, so weekend rule no extension. Good.

Potential "Calendar days include weekends" maybe in automatic-stay calculations. We can show count:
- From Sept 2 through Sept 11 inclusive = 10 days. Actually "ten calendar days after award notice" if the period starts Sept 2 and includes Sept 11: Sept 2,3,4,5,6,7,8,9,10,11 = 10. Good.
- From Sept 5 through Sept 9 inclusive = 5. Good.
Need maybe if someone counts September 2 = day 1. Good.
- From Sept 5 through Sept 14 inclusive = 10. Good.

Let's maybe create a table:

Deadline | Calculation | Date
Board merits | knowledge 9/4 excluded; count 9/5-9/14 | 9/14
Automatic stay (a) | award 9/1 excluded; count 9/2-9/11 | 9/11
Automatic stay (b) | debrief 9/4 excluded; count 9/5-9/9 | 9/9
Control for stay | later | 9/11

This is clear. Need include maybe "last filing date preserving automatic stay: 9/11." Good.

Potential "Agency-level protest would do nothing" table maybe no.

Potential "Waived solicitation ground" perhaps "If Silverline argues polar requirement on Board, the protest is subject to dismissal as to that ground; and could undermine other claims. Omit." Good.

Potential "Grounds to include—supporting facts" perhaps "State 'At the September 4 debriefing, the Authority said . . .'" to satisfy facts known. Good.

Potential "Protected access" perhaps "Request expedited consideration because Atlas is scheduled to begin transition September 13." Good. Good point: Ask Board to expedite and confirm automatic stay before Sept 13. Need include in filing sequence maybe "motion for protective order and, if needed, confirmation that stay is effective." Good.

Potential "The Board receives protest by Sept 11, automatic stay; but if Board doesn't process until Sept 13? The rule says automatically stayed; not dependent on Board action. Need perhaps "File with proof; no need to wait for Board order." Good.
Potential "If automatic stay lost, court should be asked for TRO before Sept 13. But if court relief filed after transition begins, harder." Good.

Potential "Irreparable harm" maybe "because the transition work itself may be significant enough to make corrective competition harder; plus if Atlas begins performance, a later award to Silverline would be impossible or tainted; such harm is not monetary." Good.

Potential "Likely success" maybe "The Board protest is not hopeless due to waiver; post-award grounds are preserved by debriefing." Good.

Potential "Balance and public interest" maybe "The government has an interest in proceeding, but no legitimate interest in proceeding on a potentially flawed evaluation; Atlas can be compensated for delay." Good.

Potential "Supplementation after agency report" maybe "If new facts support additional legal theories (e.g., unequal treatment, conflict of interest), assert them promptly when learned; but any known/waived ground omitted from initial protest should not be raised later." Need be careful with "fact first learned from agency report" could allow new ground. We can include "to the extent the rule permits supplementation of grounds based on facts first learned from the report, use it promptly; but do not rely on it for currently known grounds." Good.

Potential "The exact filing sequence should include 'by September 11' not 'by September 10' because if agency protest on Sept10 and Board on Sept11, okay. But "strongest" is now. Need maybe "If the desire is to maximize preparation, no later than September 10 at close; but the absolute legal deadline is Sept 11. The strongest procedural position is to file as early as possible." Good.
Potential "Board merits deadline Sept14, but automatic stay deadline Sept11; there is no reason to wait until Sept14." Good.

Potential "Agency-level protest after Board protest may be harmful?" Let's think in a GAO-like system, filing an agency-level protest after a Board/court protest might not be allowed or may be dismissed; but not specified. Maybe "optional and not necessary" is enough. The rules do not prohibit. If we want strongest procedural position, "omit agency protest unless there is a strategic reason independent of preserving rights." Good.

Potential "Court injunction if automatic stay lost" perhaps "You must first file a Board protest? If Board protest not yet filed and auto stay deadline passed, court may consider? But not specified. We can say "assuming the Board merits protest remains timely, include an explanation in the court filing." Good.

Potential "If Board protest is filed by Sept 11, the automatic stay applies even if they also file agency protest. If the Board later sua sponte determines the protest lacks merit, can lift stay; no need." Good.

Potential "Protected records" maybe "The agency report may include Atlas's trade secrets; outside counsel only. A request in initial protest preserves right. Later supplementation may rely on facts from report." Good.

Potential "Requested relief" maybe "ask for hearing if Board rules allow" but not in facts. No need.

Potential "The protest must state supporting facts then known" "The initial Board protest is based on the debriefing slides; attach them if permitted." Good.

Potential "No automatic stay from agency protest" Need mention "agency protest on Sept 10 does not stop Atlas's Sept 13 transition." Good.

Potential "What if agency issues answer to agency protest before Sept 11? It won't be automatic stay; unless it is a written suspension and maybe order. But management "waiting for answer" not enough." Good.

Potential "No written commitment to suspend performance" maybe "Agency has made no written commitment; under Rule 6, the Board deadline is not tolled." Good.

Potential "Atlas's transition work scheduled to begin Sept 13" maybe "if Board receives protest by Sept 11, Atlas and agency must not proceed; if they do, they violate automatic stay, unless stay lifted." Good.

Potential "The ten-calendar-day Board merits deadline is later than automatic stay, so if they file by Sept 11, merits also timely." Good.

Potential "Grounds to include in initial Board protest" need maybe "The price ground alone may not be sufficient if Atlas is technically superior; combine with technical scoring challenge. If the sensor-resolution and subcontractor experience contentions succeed, the price/technical tradeoff cannot be supported." Good.

Potential "The agency credited Atlas with sensor-resolution score based on a model Atlas did not identify in its proposal" Is that an "apparent solicitation defect" if the solicitation didn't require model identification? It's an evaluation error: the agency may have relied on information outside the proposal. Need maybe call "unstated evaluation criterion" not "solicitation defect." Good.
Potential "Subcontractor experience" if "solicitation clause stating relevant subcontractor experience 'will be considered'." Maybe if it didn't say how much weight, agency could assign zero? No, "will be considered" means must consider. Need say "at least some consideration; zero may be arbitrary if the experience was relevant." Good.

Potential "Atlas evaluated price $1.8M higher" "A price premium can be reasonable for superior technical; but if technical evaluation is arbitrary, tradeoff is arbitrary." Good.

Potential "The Board merits deadline after required debriefing—'matters first disclosed there'—does it extend only those grounds first disclosed; if Silverline learned other grounds from award notice? There are none. Good.

Potential "If Silverline submits an agency protest, could it request agency to suspend performance? If agency issues written suspension before Board deadline, it might toll Board deadlines, but no commitment. If desired, ask for written suspension? But the plan should not wait. Need maybe "The only way the agency-first approach could be salvaged is if the agency issues a written suspension before Sept 11; because none exists, cannot." Good.

Potential "Court's injunction standard: likely success" maybe "irreparable harm; balance of harms; public interest" exactly. Need "A court likely can award preliminary injunctive relief even after the automatic-stay deadline; but the burden is on Silverline." Good.

Potential "If automatic stay lost, Board can also grant discretionary relief" Need maybe "The Board may still grant a discretionary stay under Rule 5; ask for one in the Board protest/motion. This might be quicker than court and should be included as alternative relief." Good.
Need maybe "The initial Board protest should request 'automatic stay, and in the alternative, discretionary stay' because if Board considers after Sept 11? Actually if filed by Sept 11, automatic; if not, ask discretionary. Good. We can include in requested relief.

Potential "Exact filing sequence" maybe if Board protest filed after automatic stay deadline but before merits deadline, ask Board for discretionary stay and court TRO. But if we follow plan, no. The "strongest" sequence perhaps:
- Day 1 (Sept 7): File Board protest, including automatic stay request and protective order. 
- If agency protest desired, file "agency-level protest" later after Board filing for settlement, but don't wait.
- If agency attempts to start performance despite Board stay, file enforcement/court injunction? Not asked. But maybe no.
- After Sept 11? no need.

Potential "Filing sequence with court if stay lost" maybe "If the Board protest isn't filed by Sept 11, file it immediately (by Sept 14) to preserve merits; simultaneously move before Board/court for discretionary injunction, because performance may proceed." Good. But exact sequence says preserve strongest procedural position: "If for some reason the Board protest cannot be filed by Sept 11: file Board protest as soon as possible before Sept 14, but you lose automatic stay; seek court TRO and Board discretionary stay before Sept 13." Should we include? It may help. But maybe no need.

Potential "ordered protest plan" maybe "ordered" not "orderly" maybe wants "sequence." We'll include.

Let's think about "agency-level protest does not toll either Board deadline unless agency issues a written suspension before the Board deadline expires." If the agency-level protest is filed Sept 10 and the agency issues a written suspension on Sept 10, does automatic-stay deadline extend? It says "does not toll ... unless agency issues written suspension before Board deadline expires." It might toll "either Board deadline"; not the automatic-stay? Actually "either Board deadline" maybe merits deadline and stay deadline. If written suspension before deadline, not needed. But if no. We can mention "no written commitment; do not assume." Good.

Potential "The Board is open on every date relevant here" If "today Tuesday Sept 7", and "management proposes first filing agency protest on Sept 10" If Board protest filed on Sept 11, that's okay but if Board open Saturday. Need maybe "The agency protest on Sept 10 could consume the last full business day before the stay deadline, but if Board protest filed same day, okay." Good.

Potential "The automatic-stay deadline is 5 days after required debriefing? The later of 10 and 5: If debriefing is late, the 5-day deadline may be later, but here not." Good.

Potential "Atlas identified no model in proposal; could agency have used an 'or equal' model? The protest ground maybe 'unstated evaluation criterion/undisclosed information.' Good.

Potential "subcontractor experience as zero despite clause will be considered" Could be "unequal treatment if other offerors' subcontractor experience considered." But facts not say; maybe include "at least, failure to evaluate as promised." Good.

Potential "Price/technical tradeoff" maybe "Atlas's evaluated price was $1.8 million higher" Could be "agency did not perform a proper tradeoff because it selected based on disputed technical scoring." Good.

Potential "relief" maybe "If Board sustains, require evaluation of subcontractor experience, re-evaluation of sensor-resolution, and new best-value decision." Good.

Potential "protected access" maybe "the initial request should be broad enough to include Atlas's proposal, because Silverline needs to verify no model was identified." Good.

Potential "Supplementation after report" "The Board may issue a report with the agency's response; facts in it first known to Silverline can be raised by supplement. This doesn't excuse failure to request protected access now." Good.

Potential "Court relief if automatic stay lost" "filing in court creates no automatic stay" perhaps "So if the Board automatic stay is lost, a court injunction is necessary, not automatic." Good.

Potential "The award performance automatically stayed only if Board receives protest by later of..." "A protest filed by 11:59 pm Sept 11? If Board's filing system closed? Need not. But "Board is open" maybe office hours. Could say "by close of business on Sept 11." If e-filing available, by 11:59. Better "on or before Sept 11" and "confirm receipt." Good.

Potential "exact filing sequence" maybe:
- "File with the Board no later than 9/11; I recommend 9/7. The Board receipt date is what matters, so use a filing method that produces a timestamp."
- "If Board's e-filing system permits, file immediately after obtaining signatures; don't wait for legal memo perfection." Good maybe too practical but okay.

Potential "Date Silverline knew post-award grounds" maybe "The grounds were 'first disclosed' at the required debriefing, so they were not known before bid; not waived." Good.

Potential "The requested debriefing? It says 'required debriefing'—Rule 3 applies. There is no issue about whether Silverline requested." Good.

Potential "The waiver of polar experience" maybe "Although Silverline now argues 'unnecessarily restrictive,' that ground was apparent and known before bid. A post-award Board protest cannot assert it." Good.

Potential "Need to include 'supporting facts then known' in initial protest" If the facts are in the debriefing slides, "attach the slides as an exhibit." Good. "State that the full factual basis maybe in the slides." Good.

Potential "The Board merits deadline might also be affected by agency report supplementation? No, supplementation doesn't extend deadline for grounds known. Need "file by Sep 14; supplementation later is not a second chance." Good.

Potential "If the agency report discloses facts that reveal a previously unknown ground, is supplementation timely? Rule 8 says later supplementation permitted for facts first learned from agency report. But need not decide. Could mention "promptly supplement." Good.

Potential "The exact filing sequence should include 'not to file a premature court action if automatic stay preserved'"? No. If automatic stay preserved, no need for court; but maybe if agency violates stay, court enforcement. Not asked. Good.

Let's perhaps compose final answer:

```
Silverline can and should preserve the automatic stay, but only by filing a Board protest by September 11. The agency-first plan is contrary to the rules.

1. Waived ground...
2. Deadlines...
Table...
3. Agency-first...
4. Initial Board protest...
5. Access/supplement...
6. Court...
7. Exact sequence...
```

Need maybe include "Ordered protest plan" maybe "Sequence: (1) today, (2) etc." The user specifically "Provide an ordered protest plan addressing: ..." so table/list is okay. Let's ensure all bullet points addressed.

Let's think about "exact filing sequence Silverline should use to preserve strongest procedural position" maybe perhaps they want "File Board protest by September 11, not agency protest; if agency protest, file on Sept 10 after Board; no waiting." We can write:

**Exact filing sequence**
- Immediately (or at the latest by September 10): file the Board protest; include all content. This is the filing that preserves automatic stay if received by Sept 11. Use expedited delivery.
- Do not file agency protest first. If Silverline wants agency-level protest, file it only after the Board protest and only as an auxiliary settlement tool; do not await its answer before Board action.
- By Sept 11: confirm Board receipt; if possible obtain timestamp; if using courier, ensure delivery before close. If not received, no stay.
- After Board protest: request agency report/protected records; supplement within allowed time once report is produced.
- If agency/Atlas attempts transition despite stay/after stay lost: file enforcement/court injunction before Sept 13.
Maybe "exact" "By Sept 11" not "by Sept 10." Good.

Potential "If automatic stay is lost" maybe sequence:
- "File any necessary Board merits protest immediately (if not already) because merits deadline Sept 14. Move the Board for discretionary stay. If denied, file complaint for injunctive relief; request TRO/PI before Sept 13." Good. But if auto stay lost, perhaps because Board not filed by Sept 11; the strongest sequence could include "If it is already after Sept 11, file Board protest immediately and seek court TRO; do not file agency protest." Good.

Maybe include this as "If the deadline is missed" under court relief. Good.

Potential "court relief if automatic stay is lost" Need not include "Board discretionary stay" maybe but good.

Let's check if any "exact filing sequence" should mention "Board protest must be filed by 'later of' (a) and (b), but if the Board is open on every date relevant, the last date is Sept 11; if Board closed, next open. Because Board open, Sept 11." Good.

Potential "The day of knowledge excluded" maybe if date "knew" is Saturday, but "should have known" maybe "received slides same day." Good.

Potential "A required debriefing delays knowledge of matters first disclosed there" "It does not revive an apparent solicitation defect." Need maybe "The polar experience ground is waived even though debriefing occurred." Good.

Potential "Agency-level protest no automatic stay" Need maybe "If they file agency protest on Sept 10, the Board deadline remains Sept 11; agency answer could be after Sept 14; then Board merits protest untimely. So agency-first is doubly bad." Good.

Potential "Initial Board protest should include requested relief" "Request that the Board (1) treat the protest as timely filed, (2) impose/continue automatic stay, (3) order agency to produce record, (4) set aside award after merits and make new decision; (5) award costs/fees if available." Good.

Potential "protected access" "Also request access under protective order to the portions of the record containing confidential/proprietary information; include a proposed protective order if Board requires." Good.

Potential "supplementation after agency report" "The initial protest should say 'Silverline reserves the right to supplement upon receipt of the agency report under Rule 8.'" Good.

Potential "Do not save grounds for later" "Because Rule 8 requires state each ground, all known post-award grounds must be in initial Board protest." Good.

Potential "court relief if auto stay lost" "Seek a temporary restraining order and preliminary injunction in court; filing in court creates no automatic stay." Good.
Potential "irreparable harm" "proposal costs alone insufficient; loss of opportunity to compete, inability to obtain corrective competition, and irreparable contract performance are harms." Good.
Potential "balance/public" "injunction preserves status quo; public interest favors compliance with evaluation terms." Good.

Potential "Need to mention 'transition will make meaningful corrective competition harder' could support irreparable harm; but not enough by itself? Need "strong, specific evidence" perhaps. The prompt says transition will make meaningful corrective competition harder. We'll say "That is the key factual basis; combine with loss of fair opportunity." Good.

Potential "Atlas's scheduled transition on Sept 13" "Court/TRO should be sought before Sept 13; if stay preserved, agency must not allow transition." Good.

Potential "The automatic stay only if Board receives the protest by later date. If file agency protest on Sept 10, no Board protest. If the Board receives a Board protest by Sept 11, stay; if Board protest is received after Sept 11 but before Sept 14, merits timely but no automatic stay." Good.

Potential "The Board merits deadline (Sept 14) is after automatic stay deadline (Sept 11) due to award notice longer. This is why filing by Sept 14 is insufficient." Good.

Potential "Which date controls" "the later date controls, so the automatic stay deadline is driven by award notice, not debriefing. Good.

Potential "The agency has made no written commitment to suspend performance" maybe "a verbal or anticipated suspension not enough." Good.

Let's think if "agency-level protest does not toll either Board deadline unless agency issues written suspension before Board deadline expires" maybe "if agency issues written suspension after Sept 11 but before Board protest? It might not help because Board deadline already expired?" but no. Good.

Potential "The Board receives the protest" - if filing electronically, "received" when entered into Board's system. Need maybe "use same-day courier/e-filing" not necessary but practical. Good.

Potential "Request protected access to procurement records" maybe "Atlas proposal not identified model; protected access to proposal is necessary to confirm absence." Good.

Potential "The initial Board protest should include ground regarding Atlas's sensor score but not "model did not identify" as "unstated alternative" if model was in proposal? It did not identify; yes. Good.

Potential "If Atlas's proposal did not identify model, but agency credited based on model, that could be 'agency had outside information' or 'latent ambiguity'? No need. Good.

Potential "Subcontractor experience" maybe "the agency's zero treatment could be a failure to evaluate in accordance with stated evaluation criteria and arbitrary/capricious; it is not an attack on the five-year experience requirement" Good.

Potential "Atlas's higher price" maybe "price is not itself a defect; the defect is the tradeoff using invalid technical score." Good.

Potential "Exact filing sequence" maybe "On Sept 7, gather debriefing slides, draft Board protest. File with Board. Do not await agency answer. Request automatic stay. If court later needed, use same record." Good.

Potential "If Board protest filed today, still automatic stay even though management proposed agency protest Sept 10; no conflict if agency protest later." Good.

Potential "If file Board protest Sept 7, the Board's automatic stay begins on Sept 7; by Sept 13 no transition. Good.

Potential "What if the Board protest includes an agency report request; the Board's initial automatic stay could be 'only if Board receives protest by Sept 11', not if it is 'filed' after business? Need receipt. Use "received" in final. Good.

Potential "The date Silverline knew post-award grounds" maybe "At the debriefing, the Authority disclosed the three grounds. If Silverline knew or should have known some earlier, those elements could have earlier deadline; but facts say first time. Good."

Potential "Court injunction if automatic stay is lost" maybe "A court could enjoin transition if the agency's evaluation likely violated solicitation and the contract hasn't been fully performed. But after Sept 13, transition work could still be enjoined if balance favors; but harder." Good.

Potential "Supplementation" maybe "The agency report is produced in the Board protest, not in the agency-level protest. Waiting for agency-level answer is not the same." Good maybe.

Need perhaps include "The agency-level protest does not create the Board automatic stay, even if it requests one. Only the Board's receipt of a Board protest by Sept 11." Good.

Potential "The exact filing sequence should preserve strongest procedural position" maybe "Do not file the agency protest on September 10 and wait. Instead:
  1. File Board protest by end of day Sept 7 (or at the very latest Sept 10) with all elements.
  2. If management wants agency protest, file it after the Board protest (perhaps Sept 10) but do not await response.
  3. Confirm receipt and automatic stay before Sept 11.
  4. After agency report, supplement and prosecute."
Maybe "at the very latest Sept 10" rather than Sept 11 to give buffer. But the question asks last filing date; legal last date Sept 11. "Strongest procedural position" = don't wait until last date. Need not conflict. Could phrase "Legally, the last date is Sept 11; practically, file by Sept 7 or 10." Good.

Potential "If filing by Sept 10 is proposed agency protest; file Board protest by close on Sept 10 at latest, not wait for agency answer; this preserves stay with one-day buffer." Good.

Potential "Board is open every relevant date" perhaps if filing Sept 11 Saturday, okay. But "if filing on Sept 11, no time to correct; strong procedural position is earlier." Good.

Potential "Initial Board protest must be complete" maybe "Do not file a bare notice and amend later beyond supplementation; Rule 8 requires grounds and facts then known. Draft with enough specificity." Good.

Potential "Waived ground" maybe "It may be used in a court as evidence that Silverline lacked standing? no. Omit." Good.

Potential "Agency-level protest after Board protest" perhaps "It won't toll deadlines, but if it produces a written suspension before a deadline, it could preserve something; otherwise unnecessary." Good.

Let's maybe think about "performance is automatically stayed only if the Board receives the protest by later of ..." If the Board protest is filed "on" Sept 11 (Saturday) and Board is open, okay. If the Board is open but maybe closes at noon? Not specified. Use "by close of business." Good.

Potential "Grounds to include in initial Board protest" maybe "Do not include 'apparent solicitation defect' because pre-bid waiver; also avoid overbreadth. But can say 'The agency's application/evaluation was inconsistent with the solicitation' not 'the solicitation's five-year experience requirement is invalid.'" Good.

Potential "Protected-record access" maybe "Rule 8 requires request in initial protest; request 'protected access to the procurement record under a protective order, including Atlas's proposal and evaluation worksheets.'" Good.
Potential "Supplementation" "If the Board report reveals additional facts, supplement the existing protest; do not wait until agency-level 'answer'." Good.

Potential "Court relief if automatic stay is lost" maybe "If the agency has already allowed transition despite a preserved automatic stay, also seek enforcement. But question says if automatic stay lost, so not. Good.

Potential "Exact filing sequence "maybe "If the court is needed, file a complaint and TRO before Sept 13; if the Board stay is preserved, you likely won't need court; if agency or Atlas violates stay, you may." Good.

Let's check if any "date" miscalculation: Suppose knowledge Sept 4; ten days after excluding day of knowledge: Day 1 Sept 5, Day 2 Sept 6, Day 3 Sept 7, Day 4 Sept 8, Day 5 Sept 9, Day 6 Sept 10, Day 7 Sept 11, Day 8 Sept 12, Day 9 Sept 13, Day 10 Sept 14. Yes. If "within ten calendar days after" maybe if deadline at start of day 10? No, by end of day.
Award notice Sept 1; exclude Sept 1; day 1 Sept 2, day 10 Sept 11. Good.
Debriefing Sept 4; exclude Sept 4; day 1 Sept 5, day 5 Sept 9. Good.

Potential "later of" if Sept 11 vs Sept 9 -> Sept 11. Good.

Potential "Board merits deadline" is Sept14; but "if the Board is open on every date relevant here" no extension. If Sept 14 Tuesday. Good.

Potential "Today Tuesday Sept 7": There is enough time. If file today, no issue.

Potential "The agency made no written commitment to suspend performance." Need mention "An agency protest 'waiting for answer' cannot turn the agency answer into a suspension; if answer comes after Sept 11, no stay; if after Sept 14, no merits." Good.

Potential "Agency-level protest could trigger agency's written suspension" If they could negotiate one before Sept 11? Facts say no commitment, and management's plan "waiting for answer" doesn't. Maybe "Only an actual written suspension before the Board deadline would change this, and none is present." Good.

Potential "The court may issue an injunction..." Need maybe "Under the stated standard, the court doesn't need to find the Board's automatic stay deadline was met; it independently applies four factors." Good.

Potential "Balance of harms" "Atlas may suffer delay but not a lost contract necessarily; Silverline faces loss of legal remedy." Good.

Potential "Public interest" "Public interest is served by not allowing an award based on a possibly flawed evaluation to become irrevocable before review." Good.

Potential "If automatic stay is lost" maybe "A court may still deny injunction if Silverline waited too long (laches). File ASAP." Good maybe not necessary.

Potential "Later supplementation" "The Board report may be due after Sept 14? But merits already timely." Good.

Potential "Should initial Board protest ask for expedited proceedings because Atlas transition Sept13? Yes. Include perhaps "Because performance is scheduled to begin Sept 13, request expedited decision if needed." Good.
Potential "The Board's automatic stay may be challenged; request no lifting absent extraordinary circumstances." Good maybe.

Potential "No need to file agency protest to exhaust" perhaps not in rules. But perhaps "agency-level protest may be optional; not required for Board/court." We can say "The Board filing is the only necessary filing for the stay." Good.

Let's now prepare final answer.

Need maybe "Answer" style.

Let's draft final:

```
Silverline should file a Board protest immediately. The controlling date is September 11, 2027, not September 14.

1. Waived solicitation ground...
...
```

Let's ensure all assignment bullets are addressed. We can label.

Potential "Requested relief" in initial Board protest: "Set aside award; evaluate subcontractor experience; reevaluate sensor scores; conduct new best-value tradeoff; stay performance; produce record; award costs and such other relief." Include "and any request for protected access" maybe separate.

Potential "protected record access and supplementation" "The initial protest should request a protective order. The request is mandatory; later supplementation is limited to facts first learned from agency report. Do not wait for the report to state known grounds." Good.

Potential "court relief if automatic stay lost" "Because court filing creates no automatic stay, an injunction must be sought. Need show four factors. Focus on irreparable harm beyond bid preparation costs. Transition/performance will impair meaningful corrective competition." Good.

Need maybe "ordered filing sequence" perhaps as final section:
```
1. Today, Sept. 7: File the Board protest (complete).
2. By Sept. 11 at latest: Ensure Board receipt/timestamp; no later than close. If filing Sept. 11, acceptable but no buffer. Recommended Sept. 7/10.
3. Optional: After Board filing, file agency protest; do not wait for its answer.
4. After Board agency report: seek protected records and supplement.
5. If the stay is lost or ignored, file court TRO/PI before Sept. 13.
```
Need maybe "If an agency protest is filed, it should not be used as a reason to delay Board protest." Good.

Let's think if "Board by Sept 11" but "proposed agency protest on Sept 10" maybe if "File Board protest today; then file agency protest Sept 10; wait for agency answer? no; continue Board." Good.
Potential "If agency protest after Board causes agency to answer with corrective action, maybe Board protest can be dismissed; but no need."

Potential "If automatic stay is preserved, no need to seek court. But if Board later denies? no."

Potential "Waived solicitation ground" perhaps "Do not include in initial Board protest; do not supplement later." Good.

Potential "Grounds to include in initial Board protest" perhaps "The three grounds can be labelled:
A. Unstated evaluation criterion/evidence outside proposal.
B. Failure to evaluate according to solicitation's subcontractor-experience clause.
C. Arbitrary best-value tradeoff based on flawed technical scoring."
This is good.

Potential "supporting facts then known" maybe "The debriefing slide statements." Good.

Potential "price premium" "Atlas's evaluated price higher by $1.8M; if technical scoring corrected, no rational basis for selection." Good.

Potential "The initial Board protest should attach the debriefing slides and quote pertinent language." Good.

Potential "Protected access" "The request should include access to the agency report (or record), Atlas's proposal, evaluation forms/scoring model, source-selection document, and any price/technical tradeoff documentation." Good.

Potential "Supplementation" "State in the initial protest that Silverline reserves the right to supplement after receiving the agency report." Good.

Potential "If automatic stay is lost" maybe "The Board protest may still proceed if filed by Sept 14; but performance continues. If the Board/court grants discretionary relief, performance stops. Ask the Board for discretionary stay in the alternative." Good.

Potential "Need to mention "merits deadline" maybe if auto stay lost but Board protest filed Sept 12, still timely if by Sept14. Good.

Let's now craft final answer with moderate detail. Need avoid extraneous.

Let's maybe include a mini table:

```
Event | Date
Board merits deadline | 9/14
Stay (a) award notice | 9/11
Stay (b) debriefing | 9/9
Controlling stay | 9/11
```

Need ensure markdown table not too much. Fine.

Let's prepare final answer.

Potential issue "Board is open on every date relevant here" — Should I mention "no next-business-day extension due to Saturday"? Yes.

Potential "The first date filing Board protest by Sept 11 preserves automatic stay" If "by later of" maybe if Board receives protest on Sept 11, yes. Good.

Potential "If Board receives protest on Sept 10, also. If after Sept 11, no." Good.

Potential "The 'later of' controls; a date is later than another calendar date." Good.

Potential "Date Silverline knew post-award grounds" "The required debriefing itself disclosed them; written slides same day. Therefore day of knowledge = Sept. 4." Good.

Potential "Matter first disclosed there" "all three post-award grounds are first disclosed at debriefing; so not waived by failure to protest before award? Wait the post-award grounds could only arise after award? yes. No pre-bid issue except polar." Good.

Potential "The waiver rule applies to an 'apparent solicitation defect' not to evaluation errors. Thus the polar ground is waived but not the evaluation errors." Good.

Potential "The proposed agency-first sequence does not protect the stay because Board automatic stay only if Board receives protest by Sept11; agency protest not accepted by Board." Good.

Potential "If agency issues written suspension before Board deadline, maybe different; no written commitment." Good.

Potential "Court's irreparable harm" Need "proposal costs alone insufficient; not enough." Good.

Potential "Balance of harms" "The government and Atlas have an interest in proceeding, but the public has a stronger interest in procurement law compliance if the merits are substantial." Good.

Potential "Public interest" "An injunction preserves the status quo pending review; that is typically in public interest." Good.

Let's formulate.

Potential "The initial Board protest should request protected access and not just mention 'protected access' in a later motion." Good.

Potential "The Board's agency report" maybe "The agency will produce report; after receipt, supplement with facts first learned. If supplementation deadline not specified, do it promptly." Good.

Potential "exact filing sequence" maybe "Should not use proposed agency-first sequence." Good.

Let's write final answer now.
