Significant Accounting Policies [Abstract]
Organization and Business Operations	Note 1 — Organization and Business Operations Constellation Acquisition Corp I (the “Company”) is a newly organized blank check company incorporated in Cayman Islands on November 20, 2020. The Company was formed for the purpose of effecting a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (“Business Combination”). As of March 31, 2023, the Company had not commenced any operations. All activity through March 31, 2023 relates to the Company’s formation and the Initial Public Offering (“IPO”) which is described below, and identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the IPO. The registration statement for the Company’s IPO was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on January 26, 2021 (the “Effective Date”). On January 29, 2021, the Company consummated the IPO of 31,000,000 units (the “Units” and, with respect to the shares of Class A ordinary shares included in the Units sold, the “Public Shares”), including 1,000,000 Units issued pursuant to the partial exercise of the underwriters’ over-allotment option, at $10.00 per Unit, generating gross proceeds of $310,000,000, which is discussed in Note 3. Each Unit consists of one Class A ordinary share, and one-third of one redeemable warrant to purchase one Class A ordinary share at a price of $11.50 per whole share. Simultaneously with the closing of the IPO, the Company consummated the sale of 5,466,667 private placement warrants (the “Private Placement Warrants”), at a price of $1.50 per Private Placement Warrant, in a private placement to certain affiliates of the Company’s sponsor, Constellation sponsor GmbH & Co. KG, a German limited partnership (the “Sponsor”), generating gross proceeds of $8,200,000, which is discussed in Note 4. Transaction costs of the IPO amounted to $17,586,741 consisting of $6,200,000 of underwriting fees, $10,850,000 of deferred underwriting fees (the "Deferred Underwriting Fees"), and $536,741 of other offering costs. Following the closing of the IPO on January 29, 2021, $310,000,000 ($10.00 per Unit) from the net offering proceeds of the sale of the Units in the IPO and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”) and invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay the income taxes, if any, the Company’s amended and restated memorandum and articles of association will provide that the proceeds from the IPO and the sale of the Private Placement Warrants held in the Trust Account will not be released from the Trust Account (1) to the Company, until the completion of the initial Business Combination, or (2) to the public shareholders, until the earliest of (a) the completion of the initial Business Combination, and then only in connection with those Class A ordinary shares that such shareholders properly elected to redeem, subject to the limitations, (b) the redemption of any Public Shares properly tendered in connection with a (A) shareholder vote to amend the amended and restated memorandum and articles of association to modify the substance or timing of the Company’s obligation to provide holders of the Class A ordinary shares the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination by the date by which we are required to consummate a Business Combination pursuant to the Company’s amended and restated memorandum and articles of association (such date, the “Termination Date” and, such period, the “Combination Period”), or (B) with respect to any other provision relating to the rights of holders of the Class A ordinary shares or pre-initial Business Combination activity, and (c) the redemption of the Public Shares if the Company has not consummated the initial Business Combination within the Combination Period. Public shareholders who redeem their Class A ordinary shares in connection with a shareholder vote described in clause (b) in the preceding sentence shall not be entitled to funds from the Trust Account upon the subsequent completion of an initial Business Combination or liquidation if the Company has not consummated an initial Business Combination within the Combination Period, with respect to such Class A ordinary shares so redeemed. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the public shareholders. The Company will provide its public shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of the initial Business Combination either (i) in connection with a shareholder meeting called to approve the initial Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount then on deposit in the Trust Account (initially approximately $10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but not more than ten business days, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay the income taxes, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to the obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the warrants, which will expire worthless if the Company fails to consummate an initial Business Combination within the Combination Period. The Sponsor, officers and directors have agreed to waive their redemption rights with respect to their Founder Shares and any Public Shares purchased during or after the IPO in connection with (i) the completion of the initial Business Combination and (ii) a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association, and (iii) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to complete its initial Business Combination within the Combination Period. The Company’s Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act. However, the Company has not asked its Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether its Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Company’s Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that its Sponsor would be able to satisfy those obligations. On January 26, 2023, the Sponsor underwent a reorganization pursuant to which the limited partners of the Sponsor transferred all of their limited partnership interests to Constellation Sponsor LP, a newly formed Delaware limited partnership (the “New Sponsor”). On January 26, 2023, the Sponsor was liquidated pursuant to applicable law by the retirement of the general partner of the Sponsor (the second to last partner of the Sponsor) and all securities held by the Sponsor were distributed by operation of law to its sole remaining limited partner, the New Sponsor, following which, on January 30, 2023, control of the New Sponsor was transferred to affiliates of Antarctica Capital Partners, LLC. On January 27, 2023, the Company held the Extension Meeting to amend the Company’s amended and restated memorandum and articles of association (the “Articles Amendment”) to extend the date by which the Company has to consummate a Business Combination from January 29, 2023 (the “Original Termination Date”) to April 29, 2023 (the “Articles Extension Date”) and to allow the Company, without another shareholder vote, to elect to extend the Termination Date to consummate a Business Combination on a monthly basis for up to nine times by an additional one month each time after the Articles Extension Date, by resolution of the Company’s board of directors if requested by the Sponsor, and upon five days’ advance notice prior to the applicable Termination Date, or a total of up to twelve months after the Original Termination Date, unless the closing of the Company’s initial Business Combination shall have occurred prior to such date (the “Extension Amendment Proposal”). Upon each of the nine one-month extensions, the Sponsor or one or more of its affiliates, members or third-party designees may contribute to the Company $150,000 as a loan to be deposited into the Trust Account. The shareholders of the Company approved the Extension Amendment Proposal at the Extension Meeting and on January 31, 2023, the Company filed the Articles Amendment with the Registrar of Companies of the Cayman Islands. In connection with the vote to approve the Extension Amendment Proposal, the holders of 26,506,157 Class A ordinary shares, par value $0.0001 per share, of the Company properly exercised their right to redeem their shares for cash at a redemption price of approximately $10.167 per share, for an aggregate redemption amount of $269,485,746. On April 28, 2023, the Company drew an aggregate of $150,000 from the unsecured promissory note, dated January 30, 2023 between the Company and Constellation Sponsor LP and deposited the amount into the Company’s Trust Account. This deposit enables the Company to extend the date by which it must complete its initial Business Combination from April 29, 2023 to May 29, 2023 under the amended and restated memorandum and articles of association (see Note 9) Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that it could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these condensed financial statements. The condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty. Management acknowledges that the Company depends on a variety of U.S. and multi-national financial institutions for banking services. Market conditions can impact the viability of these institutions, which in effect will effect the Company’s ability to maintain and provide assurances that the Company can access its cash and cash equivalents in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect the Company’s liquidity, business and financial condition. In February 2022, the Russian Federation and Belarus commenced a military action with the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Further, the impact of this action and related sanctions on the world economy are not determinable as of the date of these condensed financial statements. The specific impact on the Company’s financial condition, results of operations, and cash flows is also not determinable as of the date of these condensed financial statements. Liquidity and Going Concern Consideration As of March 31, 2023, the Company had $5,864 in its operating bank account, and a working capital deficit of $1,596,683, net of the convertible promissory note - related party. The Company is within 12 months of its mandatory liquidation as of the time of filing this 10Q. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the liquidity condition and mandatory liquidation raise substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of the Business Combination or the Termination Date. These unaudited condensed financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern. As such, management plans to consummate a Business Combination prior to the mandatory liquidation date. If the Company’s estimates 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 an initial Business Combination. Moreover, the Company may need to obtain additional financing either to complete an initial Business Combination or because it becomes obligated to redeem a significant number of its Public Shares upon completion of an initial Business Combination, in which case the Company may issue additional securities or incur debt in connection with such initial Business Combination.

Note 1 — Organization and Business Operations

Constellation Acquisition Corp I (the “Company”) is a newly organized blank check company incorporated in Cayman Islands on November 20, 2020. The Company was formed for the purpose of effecting a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (“Business Combination”).

As of March 31, 2023, the Company had not commenced any operations. All activity through March 31, 2023 relates to the Company’s formation and the Initial Public Offering (“IPO”) which is described below, and identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the IPO.

The registration statement for the Company’s IPO was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on January 26, 2021 (the “Effective Date”). On January 29, 2021, the Company consummated the IPO of 31,000,000 units (the “Units” and, with respect to the shares of Class A ordinary shares included in the Units sold, the “Public Shares”), including 1,000,000 Units issued pursuant to the partial exercise of the underwriters’ over-allotment option, at $10.00 per Unit, generating gross proceeds of $310,000,000, which is discussed in Note 3. Each Unit consists of one Class A ordinary share, and one-third of one redeemable warrant to purchase one Class A ordinary share at a price of $11.50 per whole share.

Simultaneously with the closing of the IPO, the Company consummated the sale of 5,466,667 private placement warrants (the “Private Placement Warrants”), at a price of $1.50 per Private Placement Warrant, in a private placement to certain affiliates of the Company’s sponsor, Constellation sponsor GmbH & Co. KG, a German limited partnership (the “Sponsor”), generating gross proceeds of $8,200,000, which is discussed in Note 4.

Transaction costs of the IPO amounted to $17,586,741 consisting of $6,200,000 of underwriting fees, $10,850,000 of deferred underwriting fees (the "Deferred Underwriting Fees"), and $536,741 of other offering costs.

Following the closing of the IPO on January 29, 2021, $310,000,000 ($10.00 per Unit) from the net offering proceeds of the sale of the Units in the IPO and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”) and invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay the income taxes, if any, the Company’s amended and restated memorandum and articles of association will provide that the proceeds from the IPO and the sale of the Private Placement Warrants held in the Trust Account will not be released from the Trust Account (1) to the Company, until the completion of the initial Business Combination, or (2) to the public shareholders, until the earliest of (a) the completion of the initial Business Combination, and then only in connection with those Class A ordinary shares that such shareholders properly elected to redeem, subject to the limitations, (b) the redemption of any Public Shares properly tendered in connection with a (A) shareholder vote to amend the amended and restated memorandum and articles of association to modify the substance or timing of the Company’s obligation to provide holders of the Class A ordinary shares the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination by the date by which we are required to consummate a Business Combination pursuant to the Company’s amended and restated memorandum and articles of association (such date, the “Termination Date” and, such period, the “Combination Period”), or (B) with respect to any other provision relating to the rights of holders of the Class A ordinary shares or pre-initial Business Combination activity, and (c) the redemption of the Public Shares if the Company has not consummated the initial Business Combination within the Combination Period. Public shareholders who redeem their Class A ordinary shares in connection with a shareholder vote described in clause (b) in the preceding sentence shall not be entitled to funds from the Trust Account upon the subsequent completion of an initial Business Combination or liquidation if the Company has not consummated an initial Business Combination within the Combination Period, with respect to such Class A ordinary shares so redeemed.

The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the public shareholders.

The Company will provide its public shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of the initial Business Combination either (i) in connection with a shareholder meeting called to approve the initial Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount then on deposit in the Trust Account (initially approximately $10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations).

If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but not more than ten business days, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay the income taxes, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to the obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

There will be no redemption rights or liquidating distributions with respect to the warrants, which will expire worthless if the Company fails to consummate an initial Business Combination within the Combination Period.

The Sponsor, officers and directors have agreed to waive their redemption rights with respect to their Founder Shares and any Public Shares purchased during or after the IPO in connection with (i) the completion of the initial Business Combination and (ii) a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association, and (iii) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to complete its initial Business Combination within the Combination Period.

The Company’s Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act. However, the Company has not asked its Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether its Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Company’s Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that its Sponsor would be able to satisfy those obligations.

On January 26, 2023, the Sponsor underwent a reorganization pursuant to which the limited partners of the Sponsor transferred all of their limited partnership interests to Constellation Sponsor LP, a newly formed Delaware limited partnership (the “New Sponsor”). On January 26, 2023, the Sponsor was liquidated pursuant to applicable law by the retirement of the general partner of the Sponsor (the second to last partner of the Sponsor) and all securities held by the Sponsor were distributed by operation of law to its sole remaining limited partner, the New Sponsor, following which, on January 30, 2023, control of the New Sponsor was transferred to affiliates of Antarctica Capital Partners, LLC.

On January 27, 2023, the Company held the Extension Meeting to amend the Company’s amended and restated memorandum and articles of association (the “Articles Amendment”) to extend the date by which the Company has to consummate a Business Combination from January 29, 2023 (the “Original Termination Date”) to April 29, 2023 (the “Articles Extension Date”) and to allow the Company, without another shareholder vote, to elect to extend the Termination Date to consummate a Business Combination on a monthly basis for up to nine times by an additional one month each time after the Articles Extension Date, by resolution of the Company’s board of directors if requested by the Sponsor, and upon five days’ advance notice prior to the applicable Termination Date, or a total of up to twelve months after the Original Termination Date, unless the closing of the Company’s initial Business Combination shall have occurred prior to such date (the “Extension Amendment Proposal”). Upon each of the nine one-month extensions, the Sponsor or one or more of its affiliates, members or third-party designees may contribute to the Company $150,000 as a loan to be deposited into the Trust Account. The shareholders of the Company approved the Extension Amendment Proposal at the Extension Meeting and on January 31, 2023, the Company filed the Articles Amendment with the Registrar of Companies of the Cayman Islands.

In connection with the vote to approve the Extension Amendment Proposal, the holders of 26,506,157 Class A ordinary shares, par value $0.0001 per share, of the Company properly exercised their right to redeem their shares for cash at a redemption price of approximately $10.167 per share, for an aggregate redemption amount of $269,485,746.

On April 28, 2023, the Company drew an aggregate of $150,000 from the unsecured promissory note, dated January 30, 2023 between the Company and Constellation Sponsor LP and deposited the amount into the Company’s Trust Account. This deposit enables the Company to extend the date by which it must complete its initial Business Combination from April 29, 2023 to May 29, 2023 under the amended and restated memorandum and articles of association (see Note 9)

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that it could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these condensed financial statements. The condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Management acknowledges that the Company depends on a variety of U.S. and multi-national financial institutions for banking services. Market conditions can impact the viability of these institutions, which in effect will effect the Company’s ability to maintain and provide assurances that the Company can access its cash and cash equivalents in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect the Company’s liquidity, business and financial condition.

In February 2022, the Russian Federation and Belarus commenced a military action with the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Further, the impact of this action and related sanctions on the world economy are not determinable as of the date of these condensed financial statements. The specific impact on the Company’s financial condition, results of operations, and cash flows is also not determinable as of the date of these condensed financial statements.

Liquidity and Going Concern Consideration

As of March 31, 2023, the Company had $5,864 in its operating bank account, and a working capital deficit of $1,596,683, net of the convertible promissory note - related party.

The Company is within 12 months of its mandatory liquidation as of the time of filing this 10Q. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the liquidity condition and mandatory liquidation raise substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of the Business Combination or the Termination Date.

These unaudited condensed financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

As such, management plans to consummate a Business Combination prior to the mandatory liquidation date. If the Company’s estimates 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 an initial Business Combination. Moreover, the Company may need to obtain additional financing either to complete an initial Business Combination or because it becomes obligated to redeem a significant number of its Public Shares upon completion of an initial Business Combination, in which case the Company may issue additional securities or incur debt in connection with such initial Business Combination.
