Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Liquidity and Capital Resources The Company’s liquidity needs up to December 31, 2025 had been satisfied through the loan under an unsecured promissory note from the Sponsor of up to $300,000 (Note 4). As of December 31, 2025, the Company had $4,347 in cash and had a working capital deficit of $355,614. In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (the “Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans but no proceeds from the Trust Account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into Private Placement Units of the post Business Combination entity at a price of $10.00 per unit at the option of the lender. The units would be identical to the Private Placement Units. As of December 31, 2025, no such Working Capital Loans were outstanding. In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Presentation of Financial Statements—Going Concern,” the Company has completed its Initial Public Offering on February 19, 2026, at which time the capital in excess of the funds deposited in the Trust Account and/or used to fund offering costs and other expenses was released to the Company for general capital purposes. The Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination. The Company has the Completion Window to complete the initial Business Combination. Management has determined that upon the consummation of the Initial Public Offering and the sale of the Private Placement Units, the Company has sufficient funds to finance the working capital needs of the Company within one year from the date of issuance of the financial statements. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Net Loss Per Class B Ordinary Share Net loss per Class B ordinary share is computed by dividing net loss by the weighted average number of Class B ordinary shares outstanding during the period, excluding Class B ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,136,250 Class B ordinary shares that would have been subject to forfeiture had the over-allotment option not been exercised by the underwriters (see Note 5). On February 19, 2026, the Underwriters partially exercised its over-allotment option and forfeited the unexercised balance resulting in 791,167 no longer subject to forfeiture. As of December 31, 2025, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted loss per Class B ordinary share is the same as basic loss per Class B ordinary share for the period presented. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $4,347 in cash and did not have cash equivalents as of December 31, 2025. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which at times, may exceed federally insured limits. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet, primarily due to its short-term nature. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Deferred Offering Costs The Company complies with the requirements of the FASB ASC Topic 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Deferred offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. On February 19, 2026, upon the completion of the Initial Public Offering, offering costs allocated to the public shares subject to possible redemption were charged to temporary equity and offering costs allocated to the public and private placement warrants within the Units and Private Placement Units, were charged to shareholders’ deficit as public and private placement warrants included in the Units and Private Placement Units, respectively, after management’s evaluation are accounted for under equity treatment. Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2025. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands, and the Company believes it is presently not subject to income taxes or income tax filing requirements in the United States. As such, the Company’s tax provision was zero for the period presented. Warrant Instruments The Company accounts for the public and private placement warrants issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values . Share-Based Compensation The Company records share-based compensation in accordance with FASB ASC Topic 718, “Compensation-Stock Compensation,” guidance to account for its share-based compensation. It defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments are valued using the Monte Carlo model. Grants of share-based payment awards issued to non-employees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses are included in costs and operating expenses depending on the nature of the services provided in the statement of operations. Recent Accounting Pronouncements The Company does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.
