updating the lockfile.

+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    PicHost - Self-hosted image hosting
+    Copyright (C) 2026 O96u
+

+    it under the terms of the GNU General Public License version 3 as
+    published by the Free Software Foundation.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

-| Web upload                     | Session              | Current user                |
-| API upload + **user token**    | `Auth-Token`         | Token owner                 |
-| API upload + **global token**  | `Auth-Token`         | Admin (`userId` null)       |
-| Twikoo `/api/index.php`        | form `token`         | Same as global token        |
-| Gallery list / search / delete | Session or token     | Users: own only; admin: all |
-| Direct link `GET /images/...`  | None (Referer rules) | Public if URL is known      |
-
-Regular users are limited to the `images/` folder; custom `folder` requires admin or global token.
-
-## Storage layout
-
-```
-/data
-├── pichost.db          # SQLite: users, sessions, settings, logs
-├── images/             # Default upload folder
-├── blog/               # Example custom folder
-└── twikoo/             # Twikoo comment images
-```
-
-Pattern: `folder/YYYY/MM/randomId.webp` + `.meta.json`. Back up the entire `/data` directory.
-
-## API overview
-
-| Method | Path                 | Description            |
-| ------ | -------------------- | ---------------------- |
-| POST   | `/api/images/upload` | Upload image           |
-| GET    | `/api/images`        | Paginated list         |
-| DELETE | `/api/images`        | Delete one (`key`)     |
-| POST   | `/api/index.php`     | Twikoo / EasyImage 2.0 |
-
-Upload example:
-
-```bash
-curl -X POST "https://pic.example.com/api/images/upload" \
-  -H "Auth-Token: YOUR_TOKEN" \
-  -F "folder=blog" \
-  -F "image=@./demo.png"
-```
-
-Full docs and copyable cURL snippets are on the **API** page after deployment.
-
-## Twikoo
-
-| Setting           | Value                               |
-| ----------------- | ----------------------------------- |
-| `IMAGE_CDN`       | `easyimage`                         |
-| `IMAGE_CDN_URL`   | `https://your-domain/api/index.php` |
-| `IMAGE_CDN_TOKEN` | Same as `API_UPLOAD_TOKEN`          |
-
-## Reverse proxy
-
-- Proxy to port **6892**; HTTPS recommended
-- Nginx: `client_max_body_size` ≥ 12m
-- Set `IMAGE_BASE_URL` for public access
-
-## Development
-
-```bash
-npm run dev          # Dev server
-npm run build        # Production build
-npm run start        # Run .output
-npm run lint         # ESLint
-npm run typecheck    # Type check
-npm test             # Unit tests

-
-终端会打印随机新密码；用户不存在时会报错。登录后请到「修改密码」更换。
-
-本地：`npm run reset-password` 或 `npm run reset-password -- 用户名`
-
-已克隆仓库时也可用 `docker compose up -d`（见仓库内 `docker-compose.yml`）。
-
-### 本地开发
-
-```bash
-npm install
-cp .env.example .env   # 可选
-npm run dev
-```
-
-访问 `http://localhost:3000/setup` 创建管理员；数据目录默认 `./data`。
-
-### 遗留部署迁移
-
-若旧版仅配置了 `ADMIN_SECRET`、尚无用户表，可用密钥登录一次，Web 引导迁移为账号密码。

+# API
+
+PicHost exposes REST endpoints and a Twikoo-compatible upload. After deployment, open the in-app **API** page for your token and copyable cURL snippets.
+
+## Authentication
+
+All REST calls use:
+
+```http
+Auth-Token: YOUR_TOKEN
+```
+
+| Token type | How to obtain | Notes |
+| ---------- | ------------- | ----- |
+| **Global** | Admin **API** page or `API_UPLOAD_TOKEN` env | Env wins and blocks UI regenerate |
+| **Personal** | Each user’s **API** page | Uploads belong to that user |
+
+Form uploads may use field `token` (Twikoo protocol).
+
+## Endpoints
+
+### 1. Upload images
+
+`POST /api/images/upload`
+
+Upload one or more images via `image`; also accepts `file`, `files`. Stored under `images/`.
+
+```bash
+curl -X POST "https://admin.example.com/api/images/upload" \
+  -H "Auth-Token: YOUR_TOKEN" \
+  -F "image=@./demo.png"
+```
+
+### 2. List images
+
+`GET /api/images`
+
+Paginated gallery. `limit` default 20, max 100.
+
+```bash
+curl "https://admin.example.com/api/images?limit=20&page=1" \
+  -H "Auth-Token: YOUR_TOKEN"
+```
+
+### 3. Search images
+
+`GET /api/images/search`
+
+Search by filename or path; `q` is required.
+
+```bash
+curl "https://admin.example.com/api/images/search?q=demo&limit=20&page=1" \
+  -H "Auth-Token: YOUR_TOKEN"
+```
+
+### 4. Delete image
+
+`DELETE /api/images`
+
+Delete by `key` (storage path, e.g. `images/2026/08/xxx.webp`).
+
+```bash
+curl -X DELETE "https://admin.example.com/api/images?key=images/2026/08/xxxx.webp" \
+  -H "Auth-Token: YOUR_TOKEN"
+```
+
+### 5. Batch delete
+
+`POST /api/images/batch-delete`
+
+JSON body: `{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}`
+
+```bash
+curl -X POST "https://admin.example.com/api/images/batch-delete" \
+  -H "Auth-Token: YOUR_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}'
+```
+
+## Errors
+
+REST responses are JSON with `code` and `message` (`UNAUTHORIZED`, `FORBIDDEN`, `INVALID_REQUEST`, etc.). Twikoo uses EasyImage-compatible JSON.
+
+## Visibility
+
+- User token: list/search/delete own images only
+- Admin token: all images
+- Global token uploads belong to admin
+
+See [Users & permissions](./users-and-permissions.md).
+
+## Twikoo
+
+`POST /api/index.php` — [Twikoo](./twikoo.md).

+# Environment variables
+
+Configure PicHost via environment variables (Docker / `.env`) or the in-app **Settings** page. Most values prefer **SQLite** when saved; some env vars override or lock UI editing.
+
+## Priority overview
+
+| Setting | Priority (high → low) | Env overrides UI |
+| ------- | --------------------- | ---------------- |
+| API upload token | Env → SQLite | **Yes** (cannot regenerate in UI) |
+| WebP quality | SQLite → env → default 80 | No |
+| Referer whitelist | SQLite → env | No |
+| Site / image base URL | SQLite → env → request origin | No |
+| Hide `images/` prefix | SQLite → env → default false | No |
+| Date-based paths | SQLite → env → default true | No |
+| Global auto-delete days | SQLite → env → default 0 | No |
+
+## Variables
+
+### `API_UPLOAD_TOKEN`
+
+Token for external uploads (Twikoo, userscripts, blogs). Header: `Auth-Token: <token>`; form field `token` still works.
+
+- Generate in **API** page when unset
+- **When set in env, it wins** — UI shows “overridden by environment” and cannot regenerate
+- Alias: `NUXT_API_UPLOAD_TOKEN`
+
+### `ALLOWED_REFERER_HOSTS`
+
+Comma-separated Referer whitelist. Own hostnames are allowed automatically. Optional; configurable in Settings.
+
+### `SITE_BASE_URL` / `IMAGE_BASE_URL`
+
+- **Site URL**: admin UI, API, Twikoo upload
+- **Image URL**: copied links and public image URLs
+
+Single-domain: set `IMAGE_BASE_URL` only or leave empty (request origin). Dual-domain: hostnames must differ — see [Dual-domain separation](./domain-separation.md). Values must match proxy `server_name`; do not use `localhost`, IP, or unlisted hostnames for production admin access.
+
+### `HIDE_FOLDER_IN_URL`
+
+`true` hides the `images/` prefix in public URLs.
+
+### `STORAGE_USE_DATE_PATH` / `STORAGE_LAYOUT`
+
+- `true` or `STORAGE_LAYOUT=date` (default): `images/YYYY/MM/id.webp`
+- `false` or `STORAGE_LAYOUT=flat`: `images/id.webp`
+
+Also toggled in Settings.
+
+### `DATA_DIR`
+
+Root for images and SQLite. Default `./data`; `/data` in container.
+
+### `WEBP_QUALITY`
+
+Server WebP quality 1–100, default **80**.
+
+### `AUTO_DELETE_DAYS`
+
+Delete images older than N days globally; `0` disables. Affects **new uploads after enable** only. Also in Settings.
+
+### `DEV_BYPASS_ACCESS`
+
+Local dev only: `true` bypasses login. Never use in production.
+
+### Storage backends (optional)
+
+Admins usually add backends in **Storage** UI; env vars such as `STORAGE_BACKEND=s3` and `S3_*` are also supported. See [Storage](./storage.md).
+
+## Docker Compose example
+
+```yaml
+services:
+  pichost:
+    image: muxui/pichost:latest
+    ports:
+      - "6892:6892"
+    volumes:
+      - ./data:/data
+    environment:
+      SITE_BASE_URL: https://admin.example.com
+      IMAGE_BASE_URL: https://pic.example.com
+      API_UPLOAD_TOKEN: your-secret-token
+      WEBP_QUALITY: "85"
+```
+
+Restart the container after changing env vars.
+
+## Settings mapping
+
+| In-app setting | Environment variable |

+# Dual-domain separation · Recommended deployment
+
+When admin and image domains are split, the admin UI, API, and public image links use different hostnames. PicHost enforces isolation in **application middleware**: the image host only serves image paths; other requests return 404.
+
+## Architecture
+
+**One Docker instance + two domains**, both **fully reverse-proxied** to port `6892` (isolation is handled by PicHost middleware; no path splitting in Nginx).
+
+| Domain | Purpose |
+| ------ | ------- |
+| `admin.example.com` | Admin UI, API, Twikoo upload |
+| `pic.example.com` | Public image links (non-image paths blocked) |
+
+Set during `/setup` or in **Settings**:
+
+- **Site URL**: `https://admin.example.com`
+- **Image URL**: `https://pic.example.com`
+
+## Nginx example
+
+```nginx
+# admin.example.com — admin + API
+server {
+  server_name admin.example.com;
+  location / {
+    proxy_pass http://127.0.0.1:6892;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    client_max_body_size 12m;
+  }
+}
+
+# pic.example.com — same full proxy; PicHost middleware blocks non-image paths
+server {
+  server_name pic.example.com;
+  location / {
+    proxy_pass http://127.0.0.1:6892;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-Proto $scheme;
+  }
+}
+
+# Default server: reject bare IP and unknown Host values (strongly recommended in production)
+server {
+  listen 443 ssl default_server;
+  listen 80 default_server;
+  server_name _;
+  return 444;
+}
+```
+
+> Caddy, NPM, and similar tools work the same: proxy both hostnames to `http://<host>:6892` and forward `Host` and `X-Forwarded-Proto`.
+
+## Security notes
+
+### Middleware only splits the two configured hostnames
+
+PicHost uses the request **Host** (and `X-Forwarded-Host` when proxied) to decide site vs image domain:
+
+- **Image host**: non-image paths (e.g. `/`, `/settings`) → 404
+- **Site host**: image URL paths (e.g. `/images/...`) → 404
+
+If the Host is **neither** the configured site nor image hostname (e.g. `localhost`, the server **public IP**, Cloudflare **Pages** `*.pages.dev`, **Workers** `*.workers.dev`, or any other unlisted name), **the app does not block the request today** — admin and API may still be reachable. This is not about hyphenated or long domain names; it is an extra entry point outside your dual-domain pair.
+
+**Production recommendations:**
+
+1. Configure `server_name` only for the site and image hosts; add a **default server** to reject other Host values and bare IP access (see Nginx example above)
+2. With Cloudflare **orange-cloud** DNS, restrict the origin firewall to **[Cloudflare IP ranges](https://www.cloudflare.com/ips/)** so traffic cannot bypass the CDN
+3. Sign in only on the **site hostname** from Settings; do not mix `localhost`, IP, or unlisted domains
+4. Do **not** put Cloudflare Pages / Workers in front of PicHost as a **full-site reverse proxy** (extra `pages.dev` / `workers.dev` entry points worsen this issue)
+5. PicHost **cannot** run as-is on Pages/Workers (needs `node-server`, SQLite, `sharp`, local `data/`). Keep Docker/VPS; use orange-cloud DNS and optional R2 storage on CF
+
+### Cloudflare orange cloud (incl. preferred edge IPs)
+
+**Recommended:** both `admin.example.com` and `pic.example.com` **DNS Proxied** → origin Nginx / 1Panel → port `6892`, SSL **Full (strict)** (origin cert or Cloudflare Origin Certificate).
+
+| Feature | Notes |
+| ------- | ----- |
+| Orange-cloud CDN | Compatible with dual-domain; preserve `Host` and `X-Forwarded-Proto` on origin |
+| DNS “preferred IP” setups | Only changes which CF edge IP clients hit; Host stays your real domain |
+| R2 storage | Add an R2 backend under **Storage**; independent of orange cloud |
+| `cloudflare` Git branch | R2-focused deployment line; still Docker, **not** Workers hosting |
+
+**Do not confuse** “Create Worker” in the CF dashboard (Git + `wrangler deploy`) with deploying PicHost — the repo uses `nitro.preset: 'node-server'` and is not Workers-ready.
+
+See [Reverse proxy](./reverse-proxy.md#cloudflare-orange-cloud) for origin hardening.
+
+## FN NAS · Lucky reverse proxy
+
+In [Lucky](https://github.com/gdy666/lucky), create one **reverse proxy** rule per domain. **Frontend** is the public hostname; **backend** is PicHost on your LAN (e.g. `http://192.168.8.3:6892`).
+
+**Site domain (admin)**
+
+| Field | Example |
+| ----- | ------- |
+| Service type | Reverse proxy |
+| Frontend | `admin.pichost.com` |
+| Backend | `http://192.168.8.3:6892` |
+
+**Image domain**
+
+| Field | Example |
+| ----- | ------- |
+| Service type | Reverse proxy |
+| Frontend | `image.pichost.com` |
+| Backend | `http://192.168.8.3:6892` |
+
+Both rules can point to the same backend; PicHost applies host-based isolation automatically.
+
+## Environment variables (optional)
+
+```env
+SITE_BASE_URL=https://admin.example.com
+IMAGE_BASE_URL=https://pic.example.com
+```
+
+See [Environment variables](./configuration.md).
+
+## Local testing (Windows / macOS)
+
+### 1. Edit hosts
+
+```text
+127.0.0.1 admin.pichost.test
+127.0.0.1 pic.pichost.test
+```
+
+Prefer the `.test` TLD; avoid `.local` where it conflicts with mDNS.
+
+### 2. Start dev server
+
+```bash
+npm run dev
+```
+
+Dev binds `127.0.0.1:3000` by default. If the hostname resolves but the browser cannot connect, check whether dev is listening on IPv6 `::1` only.
+
+### 3. Configure dual domains
+
+| Field | Example |
+| ----- | ------- |
+| Site URL | `http://admin.pichost.test:3000` |
+| Image URL | `http://pic.pichost.test:3000` |
+
+Always open admin on the **site hostname**, not `localhost` (cookies and Host must match).
+
+### 4. Expected behavior
+
+| URL | Expected |
+| --- | -------- |
+| `http://admin.pichost.test:3000/` | Admin UI works |
+| `http://admin.pichost.test:3000/images/...` or `/2026/08/xxx.webp` | **404** (use image host) |
+| `http://pic.pichost.test:3000/` | **404** (image host has no admin) |
+| `http://pic.pichost.test:3000/images/...` | Image served |
+| `http://localhost:3000/` or `http://127.0.0.1:3000/` | **Admin still loads** (third Host — isolation skipped; OK for dev only; block at proxy in production) |
+
+After upload, copied links should use `pic.pichost.test`; gallery thumbnails should load.
+
+## Notes
+
+- Hostnames must **differ** (same machine, different subdomains is fine)
+- Site / image URLs in Settings must **exactly match** proxy `server_name` (including `www` or not)
+- No separate static root on the image domain; unlike EasyImages, PicHost isolates in-app
+- Single-domain setups can skip separation and use `IMAGE_BASE_URL` or the request host
+- When Referer protection is enabled, site and image hosts are whitelisted automatically

+# FAQ
+
+## Forgot the admin password?
+
+With `docker exec` access:
+
+```bash
+docker exec pichost reset-password
+docker exec pichost reset-password <username>
+```
+
+Local: `npm run reset-password`. See [Quick start](./getting-started.md#forgot-password).
+
+## Why can’t I regenerate the API token in the UI?
+
+`API_UPLOAD_TOKEN` in the environment **locks** the token. Change env and **restart**. See [Environment variables](./configuration.md#api-upload-token).
+
+## Hotlink / Referer errors?
+
+Check the **Referer whitelist** (`ALLOWED_REFERER_HOSTS` or Settings). Referring sites must be listed; PicHost’s own hosts and dual-domain pair are allowed automatically.
+
+## Why can admin load on pages.dev / workers.dev / IP with dual-domain?
+
+Dual-domain isolation only splits paths on the **configured site and image hostnames**. Other Host values (`localhost`, public IP, Cloudflare **Pages** `*.pages.dev`, **Workers** `*.workers.dev`, etc.) are **not blocked today**, so admin may appear on unexpected URLs.
+
+Common cause: **full-site reverse proxy** via Pages/Workers on top of orange-cloud DNS, or an origin that accepts any Host / bare IP.
+
+Fix: use only the two configured domains; add a default `server_name` block; with orange cloud, allow only CF IPs on the origin. See [Security notes](./domain-separation.md#security-notes).
+
+## Can I deploy PicHost on Cloudflare Workers / Pages?
+
+**Not with the current codebase.** PicHost needs `node-server`, SQLite, `sharp`, and local `data/` — use Docker/VPS. Connecting the repo in “Create Worker” will not deploy successfully.
+
+Recommended: run PicHost on origin; use **proxied DNS** (and optional **R2** storage). Do not full-proxy the app through Pages/Workers.
+
+## Dual-domain: admin works but thumbnails break?
+
+- Verify **IMAGE_BASE_URL** and proxy to the same instance
+- Always open admin on the **site hostname**, not mixed with `localhost`
+- See [Dual-domain separation](./domain-separation.md)
+
+## Undeletable gallery items after v1.2 upgrade?
+
+Likely **orphan index** rows (no file on disk). Startup sync removes them on restart. See [v1.2 migration](./migration.md#step-2-startup-index-sync-automatic).
+
+## Do I still need `data/blog/` after migration?
+
+After `migrate --apply`, files live under `data/images/blog/`. Remove leftover empty dirs after backup if you like; dirs with non-image files are kept by the CLI.
+
+## Object storage only — run migrate?
+
+No. Skip the CLI; startup sync focuses on local `data/images/` scanning.
+
+## Replace old image URLs in posts?
+
+Use `data/mapping.json` from `migrate` preview. Keys are **storage paths**, not full legacy URLs. See [Migration](./migration.md#urls).
+
+## Skip login during development?
+
+`DEV_BYPASS_ACCESS=true` (local only). Use `/setup` for normal flows.

+# Quick start
+
+PicHost is a self-hosted image host for NAS, home servers, or VPS. Docker is recommended; the first visit runs a web wizard to create the admin account.
+
+## Try it online
+
+| Branch | Notes |
+| ------ | ----- |
+| **main** | No public demo — see [screenshots](./index.md#screenshots) or the repository README |
+| **cloudflare** | R2-only live demo: [pic.roven.cc](https://pic.roven.cc) |
+
+## Docker (recommended)
+
+```bash
+docker run -d \
+  --name pichost \
+  -p 6892:6892 \
+  -v ./data:/data \
+  --restart unless-stopped \
+  muxui/pichost:latest
+```
+
+Default port: **6892**. Open `http://<host>:6892` and complete setup.
+
+If you cloned the repo:
+
+```bash
+docker compose up -d
+```
+
+See `docker-compose.yml` in the repository.
+
+## First-time setup
+
+1. Open your instance URL (Docker default `http://<host>:6892`).
+2. Complete `/setup` with admin username and password.
+3. (Optional) Configure site URL, image URL, Referer rules — see [Environment variables](./configuration.md) and [Dual-domain separation](./domain-separation.md).
+4. Upload from the home page; admins can open **Storage**, **Settings**, and **API**.
+
+## Sign in
+
+Management pages (upload, stats, settings, etc.) require login. Enter username and password, **drag the slider to align with the gap**, then click **Sign in**.
+
+![Login](/screenshots/login.png)
+
+If registration is enabled, create an account from the register page. Legacy deployments may still use a secret key (see the on-screen hint).
+
+## Forgot password
+
+Requires `docker exec` (server access):
+
+```bash
+docker exec pichost reset-password              # admin only when there is exactly one
+docker exec pichost reset-password <username> # admin or regular user
+```
+
+A random password is printed. Change it after login.
+
+Local dev: `npm run reset-password` or `npm run reset-password -- <username>`
+
+## Upgrading to v1.2.0
+
+If `data/` has legacy top-level folders next to `images` (e.g. `blog/`, `twikoo/`), read the [v1.2 migration guide](./migration.md) first.
+
+Object-storage-only or files already under `data/images/` — pull the new image and restart.

+# v1.2.0 local disk migration guide
+
+From v1.2.0, **all local image files** live under `data/images/`; SQLite `keys` also start with `images/`. Legacy top-level folders next to `images` (e.g. `data/blog/`, `data/twikoo/`) are no longer used.
+
+Migration is **two steps**: run the **CLI** to move files on disk, then let **startup sync** align the SQLite index.
+
+---
+
+## Migrating from other image hosts (EasyImage, Lsky, Chevereto, …)
+
+There is **no** dedicated “pull from URLs” or “import via vendor API” tool. Moving from **legacy PicHost** or **another self-hosted** install uses the same **local file** workflow:
+
+1. Locate the **image files** on the old server (copy the tree, not just the database).
+2. Place them under PicHost `data/` as a **top-level folder** next to `images` (any name — it becomes `images/{name}/...`).
+3. Run `migrate` / `migrate --apply`, then restart PicHost.
+
+| Source | Typical path on old server | After copy into PicHost |
+| ------ | -------------------------- | ----------------------- |
+| PicHost v1.1.x | `data/blog/`, `data/twikoo/` | Already under `data/` → run `migrate` |
+| EasyImage(s) | `i/` or `upload/` | e.g. `data/easyimage/` → `migrate` |
+| Lsky | `public/uploads/` etc. | e.g. `data/lsky/` → `migrate` |
+| Chevereto etc. | `images/` or `content/` | e.g. `data/chevereto/` → `migrate` |
+| Custom | your folder name | `data/your-folder/` → `migrate` |
+
+The CLI scans **every top-level directory under `data/` except `images`**, not only `blog` / `twikoo`.
+
+**Limits:** files only — accounts, tokens, and old public URLs are not imported. `mapping.json` maps old **storage keys**, not full old-site URLs. For S3/R2-only legacy hosts, sync blobs to `data/…` or attach the bucket in PicHost **Storage** settings.
+
+---
+
+## Layout before and after
+
+### Before (typical v1.1.x)
+
+```
+/data
+├── pichost.db
+├── blog/
+│   └── 2026/08/TeKJ2fD6cB6j.webp
+├── twikoo/
+└── images/
+```
+
+Index keys might look like `blog/2026/08/TeKJ2fD6cB6j.webp`.
+
+### After (v1.2.0)
+
+```
+/data
+├── pichost.db
+├── mapping.json
+└── images/
+    ├── blog/
+    │   └── 2026/08/TeKJ2fD6cB6j.webp
+    └── twikoo/
+```
+
+Index key: `images/blog/2026/08/TeKJ2fD6cB6j.webp`.
+
+---
+
+## Step 1: CLI file migration
+
+Run **before or after** upgrading the image; backup `data/` first.
+
+```bash
+docker exec pichost migrate          # preview + mapping.json
+docker exec pichost migrate --apply  # move files
+```
+
+Local: `npm run migrate` / `npm run migrate -- --apply`.
+
+| Item | Behavior |
+| ---- | -------- |
+| Scan | Every top-level directory under `data/` **except `images`** |
+| Target | `data/images/{original-top-dir}/{relative-path}` |
+| Extensions | jpg, jpeg, png, webp, gif, svg, ico |
+| Sidecar | `.meta.json` next to an image is moved if present |
+| Other files | Not moved; parent directory kept if anything remains |
+| Mapping | `data/mapping.json` — old key → new key |
+
+Script: `server/cli/migrate-to-single-images.mjs`.
+
+---
+
+## Step 2: Startup index sync (automatic)
+
+Runs on every start (`npm run dev`, Docker). No manual command.
+
+```text
+[INFO] 开始同步图片索引：扫描本地磁盘 ...
+[INFO] 磁盘扫描完成：...
+[INFO] 开始归一化遗留图片路径 ...
+[INFO] 开始校验索引与磁盘一致性，清理无文件的孤儿记录
+[INFO] 图片索引同步结束
+```
+
+| Step | Purpose |
+| ---- | ------- |
+| Scan `data/images/` | Insert missing index rows for files on disk |
+| Normalize legacy keys | `blog/...` → `images/blog/...` when files are in place |
+| Purge orphans | Remove index rows with no file on disk |
+| Repair Content-Type | Fix `application/octet-stream` entries |
+
+The CLI only **moves files**. Index alignment runs at startup — **restart** after `migrate --apply`.
+
+---
+
+## Recommended upgrade flow
+
+1. Backup `data/`.
+2. `docker exec pichost migrate` — review output and `mapping.json`.
+3. `docker exec pichost migrate --apply`.
+4. Deploy v1.2.0 and restart.
+5. Check logs for successful index sync.
+6. Use `mapping.json` to update external URLs if needed.
+
+Skip step 1 if you only use object storage or everything is already under `data/images/`.
+
+---
+
+## URLs
+
+| Old key | `blog/TeKJ2fD6cB6j.webp` |
+| New key | `images/blog/TeKJ2fD6cB6j.webp` |
+
+With “hide folder” mode, short URLs like `/TeKJ2fD6cB6j.webp` may still resolve by filename. Use `mapping.json` for bulk replacements.

+# Reverse proxy
+
+In production, terminate HTTPS with Nginx, Caddy, NPM (Nginx Proxy Manager), or your NAS proxy and forward to PicHost on port **6892**.
+
+## Basics
+
+- Upstream: `http://127.0.0.1:6892` (or host IP)
+- Forward: `Host`, `X-Forwarded-Proto` (and `X-Forwarded-For` as needed)
+- Body size: Nginx `client_max_body_size 12m` or larger
+- Use **HTTPS** on the public edge
+
+## Single domain (Nginx)
+
+Admin, API, and images on one hostname:
+
+```nginx
+server {
+  server_name pic.example.com;
+  location / {
+    proxy_pass http://127.0.0.1:6892;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    client_max_body_size 12m;
+  }
+}
+```
+
+Optional:
+
+```env
+IMAGE_BASE_URL=https://pic.example.com
+```
+
+Without `IMAGE_BASE_URL`, PicHost infers the public URL from forwarded headers.
+
+## Dual domains
+
+Both hostnames can fully proxy to the same port; isolation is enforced in PicHost middleware.
+
+See [Dual-domain separation](./domain-separation.md).
+
+## Cloudflare orange cloud
+
+Run PicHost on **your server / Docker** (port `6892`). On Cloudflare:
+
+| Practice | Notes |
+| -------- | ----- |
+| **Proxied DNS** | Both admin and image hostnames → origin proxy to `6892`, SSL **Full (strict)** |
+| Preferred edge IPs | Compatible; Host remains your real domain |
+| **R2** | Object storage backend in **Storage**; not the same as hosting the app on Pages |
+| Origin firewall | Allow only [Cloudflare IPs](https://www.cloudflare.com/ips/); do not expose `6892` publicly |
+
+**Avoid:**
+
+- **Cloudflare Pages** (`*.pages.dev`) or **Workers** (`*.workers.dev`) as a **full-site reverse proxy** to PicHost — extra hostnames can bypass dual-domain isolation ([Security notes](./domain-separation.md#security-notes))
+- “Create Worker” from Git on this repo — `node-server` preset is not Workers-ready
+
+## Origin hardening (dual-domain)
+
+PicHost middleware does **not** reject unlisted Host values. Complement with:
+
+1. **`server_name` allowlist** — site + image hosts only; `default_server` blocks bare IP and unknown Host
+2. **Do not expose 6892 on the public Internet** — only local reverse proxy; public 80/443 only
+3. **Orange cloud** — origin firewall limited to Cloudflare IP ranges
+
+## Caddy
+
+```caddy
+pic.example.com {
+  reverse_proxy 127.0.0.1:6892
+}
+```
+
+Add a second site block for the second hostname with the same upstream.
+
+## Caching
+
+Image 404/403 and domain-isolation 404 responses are **no-cache** to avoid sticky CDN errors. Be careful caching API paths behind a CDN.

+# Storage
+
+PicHost supports **local disk** and **S3-compatible object storage** (Cloudflare R2, Tencent COS, Alibaba OSS, AWS S3, etc.). Admins manage backends at **Storage** (`/storage`); new uploads go to the **default** backend.
+
+![Storage management](/screenshots/storage.png)
+
+## Layout (local)
+
+```
+/data
+├── pichost.db          # SQLite: users, sessions, settings, storage_backends, images index
+└── images/             # All files when using local backend
+```
+
+- New uploads: `images/randomId.webp` or `images/YYYY/MM/randomId.webp` (flat mode in Settings)
+- Migrated legacy: `images/blog/...` and similar
+- With cloud backends, blobs live in the bucket; index stays in SQLite `images`
+
+All **keys** start with `images/`. The upload API does **not** accept a `folder` parameter.
+
+## Adding a backend
+
+1. Sign in as admin → **Storage** → **Add backend**.
+2. Choose **local disk** or **S3-compatible** (R2 / COS / OSS presets).
+3. Enter connection details (bucket, endpoint, keys).
+4. **Set as default** so new uploads use it.
+
+### Cloudflare R2
+
+| Field | Value |
+| ----- | ----- |
+| Endpoint | `https://<account_id>.r2.cloudflarestorage.com` |
+| Region | `auto` |
+| Bucket | Your R2 bucket name |
+| Keys | R2 API token access / secret |
+
+The **cloudflare** branch streamlines R2-only deploys; see branch notes on the [docs overview](./index.md).
+
+### Environment variables (optional)
+
+Some installs seed a default S3 backend via `STORAGE_BACKEND=s3`, `S3_ENDPOINT`, `S3_BUCKET`, `S3_ACCESS_KEY`, `S3_SECRET_KEY`, `S3_REGION`. **UI-configured backends live in SQLite** alongside env-based defaults.
+
+## URL modes
+
+| Mode | Behavior |
+| ---- | -------- |
+| **proxy** | Serve via PicHost (`GET /images/...`) |
+| **public** | 302 redirect to bucket/CDN public URL |
+
+Copied links use **IMAGE_BASE_URL**. “Hide folder prefix” may shorten URLs; the server resolves by path or basename.
+
+## Usage & gallery filter
+
+- Per-backend usage on the Storage page
+- Gallery filter by backend (admin)
+
+## Backup
+
+Back up `data/images/`, `data/pichost.db`, and bucket objects.

+Upgrading from v1.1.x with parallel folders: [v1.2 migration](./migration.md).

+# API
+
+PicHost 提供 REST 接口与 Twikoo 兼容端点。部署后登录 **API** 页可查看当前 Token 与可复制 cURL 示例。
+
+## 鉴权
+
+所有 REST 接口使用请求头：
+
+```http
+Auth-Token: YOUR_TOKEN
+```
+
+| Token 类型 | 获取方式 | 说明 |
+| ---------- | -------- | ---- |
+| **全局 Token** | 管理员 **API** 页生成；或 `API_UPLOAD_TOKEN` 环境变量 | 环境变量优先且锁定后台重新生成 |
+| **个人 Token** | 各用户 **API** 页 | 仅用于该用户脚本，上传归属本人 |
+
+表单上传仍可使用字段 `token`（Twikoo 协议）。
+
+## 接口列表
+
+### 1. 上传图片
+
+`POST /api/images/upload`
+
+上传单张或多张图片。字段 `image` 传图片；仍兼容 `file`、`files`。存入 `images/`。
+
+```bash
+curl -X POST "https://admin.example.com/api/images/upload" \
+  -H "Auth-Token: YOUR_TOKEN" \
+  -F "image=@./demo.png"
+```
+
+### 2. 获取图片列表
+
+`GET /api/images`
+
+分页列出图库。`limit` 默认 20、最大 100。
+
+```bash
+curl "https://admin.example.com/api/images?limit=20&page=1" \
+  -H "Auth-Token: YOUR_TOKEN"
+```
+
+### 3. 搜索图片
+
+`GET /api/images/search`
+
+按文件名或路径关键词搜索，参数 `q` 必填。
+
+```bash
+curl "https://admin.example.com/api/images/search?q=demo&limit=20&page=1" \
+  -H "Auth-Token: YOUR_TOKEN"
+```
+
+### 4. 删除图片
+
+`DELETE /api/images`
+
+通过 `key` 删除单张，`key` 为存储路径（如 `images/2026/08/xxx.webp`）。
+
+```bash
+curl -X DELETE "https://admin.example.com/api/images?key=images/2026/08/xxxx.webp" \
+  -H "Auth-Token: YOUR_TOKEN"
+```
+
+### 5. 批量删除
+
+`POST /api/images/batch-delete`
+
+请求体 JSON：`{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}`
+
+```bash
+curl -X POST "https://admin.example.com/api/images/batch-delete" \
+  -H "Auth-Token: YOUR_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}'
+```
+
+## 错误格式
+
+REST 接口返回 JSON，含 `code` 与 `message`（如 `UNAUTHORIZED`、`FORBIDDEN`、`INVALID_REQUEST`）。Twikoo 端点使用 EasyImage 兼容 JSON 格式。

+# 环境变量
+
+PicHost 支持通过环境变量（Docker / `.env`）与后台 **设置** 页配置。多数项 **SQLite 优先**；部分项环境变量可覆盖或锁定后台编辑。
+
+## 优先级总览
+
+| 配置项 | 优先级（高 → 低） | 环境变量覆盖后台 |
+| ------ | ----------------- | ---------------- |
+| API 上传 Token | 环境变量 → SQLite | **是**（设了则后台无法重新生成） |
+| WebP 质量 | SQLite → 环境变量 → 默认 80 | 否（未在 DB 存时读 env） |
+| 防盗链白名单 | SQLite → 环境变量 | 否 |
+| 网站 / 图片域名 | SQLite → 环境变量 → 当前请求 | 否 |
+| 隐藏 `images/` 前缀 | SQLite → 环境变量 → 默认 false | 否 |
+| 按年/月分组存储 | SQLite → 环境变量 → 默认 true | 否 |
+| 全局自动删除天数 | SQLite → 环境变量 → 默认 0 | 否 |
+
+## 变量说明
+
+### `API_UPLOAD_TOKEN`
+
+外部脚本上传 Token（Twikoo / 油猴 / 博客）。请求头：`Auth-Token: <token>`；表单上传仍可用 `token` 字段。
+
+- 未配置时可在后台 **API** 页生成
+- **环境变量一旦设置，优先级最高**，后台显示「由环境变量覆盖」且无法重新生成
+- 别名：`NUXT_API_UPLOAD_TOKEN`
+
+### `ALLOWED_REFERER_HOSTS`
+
+防盗链白名单，逗号分隔域名。自身域名自动放行。可选；不填可在设置页配置。若环境变量有值且 SQLite 未存，则使用环境变量。
+
+### `SITE_BASE_URL` / `IMAGE_BASE_URL`
+
+- **网站域名**：管理后台、API、Twikoo 上传入口
+- **图片域名**：复制链接与直链使用的公网地址
+
+双域名分离需两者主机名不同，详见 [双域名分离](./domain-separation.md)。填写后须与反代 `server_name` 一致；**勿**通过 `localhost`、IP 或未配置的域名访问生产后台。
+
+### `HIDE_FOLDER_IN_URL`
+
+`true` 时直链隐藏 `images/` 前缀（如 `images/2026/08/a.webp` → `/2026/08/a.webp` 或仅文件名，取决于路径模式）。
+
+### `STORAGE_USE_DATE_PATH` / `STORAGE_LAYOUT`
+
+- `STORAGE_USE_DATE_PATH=true`（默认）或 `STORAGE_LAYOUT=date`：新图保存为 `images/年/月/随机ID.webp`
+- `false` 或 `STORAGE_LAYOUT=flat`：保存为 `images/随机ID.webp`
+
+也可在设置页切换。
+
+### `DATA_DIR`
+
+图片与 SQLite 根目录。默认 `./data`，容器内为 `/data`。
+
+### `WEBP_QUALITY`
+
+服务端 WebP 压缩质量 1–100，默认 **80**。
+
+### `AUTO_DELETE_DAYS`
+
+全局自动删除超过 N 天的图片，`0` 表示关闭。启用后仅影响**之后新上传**的图片（与按用户策略一致）。也可在设置页配置。
+
+### `DEV_BYPASS_ACCESS`
+
+仅本地开发：`true` 绕过登录验证。生产环境勿用。
+
+### 存储后端（可选）
+
+管理员通常在 **存储** 页添加后端；也可用环境变量引导（如 `STORAGE_BACKEND=s3` 与 `S3_*`）。详见 [存储](./storage.md)。
+
+## Docker Compose 示例
+
+```yaml
+services:
+  pichost:
+    image: muxui/pichost:latest
+    ports:
+      - "6892:6892"
+    volumes:
+      - ./data:/data
+    environment:
+      SITE_BASE_URL: https://admin.example.com
+      IMAGE_BASE_URL: https://pic.example.com
+      API_UPLOAD_TOKEN: your-secret-token
+      WEBP_QUALITY: "85"
+```
+
+修改环境变量后需 **重启容器** 才能生效（Token、质量等读取在启动时或请求时按实现读取）。
+
+## 与后台设置对照
+
+| 后台设置项 | 对应环境变量 |
+| ---------- | ------------ |
+| API Token | `API_UPLOAD_TOKEN` |

+- **图片域**：仅放行图片路径；其余请求返回 404
+
+## 架构说明
+
+**单 Docker 实例 + 两个域名**，均可 **全量反代** 到 `6892`（隔离由 PicHost 中间件负责，无需在 Nginx 层拆分路径）。
+
+| 域名 | 用途 |
+| ---- | ---- |
+| `admin.example.com` | 管理后台、API、Twikoo 上传 |
+| `pic.example.com` | 图片直链（中间件拦截非图片路径） |
+
+初始化时在 `/setup` 或后台 **设置** 中填写：
+
+- **网站域名**：`https://admin.example.com`
+- **图片域名**：`https://pic.example.com`
+
+## Nginx 示例
+
+```nginx
+# admin.example.com — 后台 + API（不出图，直链请走图片域）
+server {
+  server_name admin.example.com;
+  location / {
+    proxy_pass http://127.0.0.1:6892;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    client_max_body_size 12m;
+  }
+}
+
+# pic.example.com — 同样全量反代；PicHost 中间件会拦截非图片路径
+server {
+  server_name pic.example.com;
+  location / {
+    proxy_pass http://127.0.0.1:6892;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-Proto $scheme;
+  }
+}
+
+# 默认 server：拒绝裸 IP、未配置域名等其它 Host（生产环境强烈建议）
+server {
+  listen 443 ssl default_server;
+  listen 80 default_server;
+  server_name _;
+  return 444;
+}
+```
+
+> Caddy、NPM（Nginx Proxy Manager）等工具同理：两个域名均反代到 `http://<主机>:6892`，并保留 `Host` 与 `X-Forwarded-Proto` 头。
+
+## 安全与注意事项
+
+### 中间件只隔离「已配置的两个域名」
+
+PicHost 根据请求 **Host**（反代会转发为 `X-Forwarded-Host`，应用会一并识别）判断当前是网站域还是图片域：
+
+- **图片域**：非图片路径（如 `/`、`/settings`）→ 404
+- **网站域**：图片直链路径（如 `/images/...`）→ 404
+
+若 Host **既不是网站域也不是图片域**（例如 `localhost`、服务器 **公网 IP**、Cloudflare **Pages** 的 `*.pages.dev`、**Workers** 的 `*.workers.dev`、或其它未在设置里填写的域名），**当前版本不会拦截**，后台与 API 仍可能被访问。这与域名是否带 `-`、长短无关，而是多了一条未纳入双域名配置的入口。
+
+**生产环境建议：**
+
+1. 反代层仅为网站域、图片域配置 `server_name`，并增加 **default server** 拒绝其它 Host 与裸 IP（见上方 Nginx 示例）
+2. 使用 Cloudflare **橙云** 时，源站防火墙 **仅放行 [Cloudflare IP 段](https://www.cloudflare.com/ips/)**，避免绕过 CDN 直连源站
+3. **仅使用** 设置中的网站域名登录后台，不要用 `localhost`、IP 或未配置的域名混用
+4. **不要** 用 Cloudflare Pages / Workers 对 PicHost **整站反代**（会多出 `pages.dev` / `workers.dev` 等第三入口，且易出现上述绕过）
+5. PicHost **不能** 作为 Node 应用直接部署到 Pages/Workers（依赖 `node-server`、SQLite、`sharp` 与本地 `data/`）；应用请继续 Docker/VPS 部署，CF 侧用橙云 DNS + 可选 R2 存储即可
+
+### Cloudflare 橙云（含 DNS 优选）
+
+**推荐架构：** `admin.example.com` 与 `pic.example.com` 均 **DNS Proxied（橙云）** → 源站 Nginx / 1Panel 反代 `6892`，SSL 模式 **Full (strict)**（源站可用 Cloudflare Origin Certificate）。
+
+| 能力 | 说明 |
+| ---- | ---- |
+| 橙云 CDN | 与 PicHost 双域名兼容；回源须保留 `Host`、`X-Forwarded-Proto` |
+| DNS 优选 | 仅改变用户连到 CF 边缘的 IP，Host 仍为正式域名，无额外配置 |
+| R2 对象存储 | 在 **存储** 页添加 R2 后端即可，与是否橙云无关 |
+| `cloudflare` Git 分支 | R2 专用部署线，仍是 Docker 运行，**不是** Workers 托管 |
+
+**勿混淆：** CF 控制台「创建 Worker」并连接本仓库 **无法** 直接部署 PicHost；`npm run build` + `wrangler deploy` 与当前 `node-server` 预设不兼容。
+
+反代与源站加固详见 [反向代理](./reverse-proxy.md#cloudflare-橙云)。
+
+## 飞牛 NAS · Lucky 反向代理
+
+在 [Lucky](https://github.com/gdy666/lucky) 中为两个域名各建一条 **反向代理** 规则，**前端地址** 填公网域名，**后端地址** 填 PicHost 所在内网 IP 与端口（如 `http://192.168.8.3:6892`）。
+
+**网站域名（管理后台）**
+
+| 项 | 示例值 |
+| -- | ------ |
+| 服务类型 | 反向代理 |
+| 前端地址 | `admin.pichost.com` |
+| 后端地址 | `http://192.168.8.3:6892` |
+
+**图片域名**
+
+| 项 | 示例值 |
+| -- | ------ |
+| 服务类型 | 反向代理 |
+| 前端地址 | `image.pichost.com` |
+| 后端地址 | `http://192.168.8.3:6892` |
+
+两条规则的后端地址相同即可；域名分离与路径隔离由 PicHost 根据请求 `Host` 自动处理。
+
+## 环境变量（可选）
+
+除 Web 设置外，也可在 `.env` 或 Docker 环境中配置：
+
+```env
+SITE_BASE_URL=https://admin.example.com
+IMAGE_BASE_URL=https://pic.example.com
+```
+
+详见 [环境变量](./configuration.md)。
+
+## 本地测试（Windows / macOS）
+
+### 1. 修改 hosts
+
+```text
+127.0.0.1 admin.pichost.test
+127.0.0.1 pic.pichost.test
+```
+
+建议使用 `.test` 后缀，避免 `.local` 在部分系统上与 mDNS 冲突。
+
+### 2. 启动开发服务
+
+```bash
+npm run dev
+```
+
+项目已默认绑定 `127.0.0.1:3000`（与 hosts 的 IPv4 一致）。若曾出现 `ping` 通但浏览器连不上，多半是 dev 只监听了 IPv6 `::1`。
+
+### 3. 填写双域名
+
+| 项 | 示例 |
+| -- | ---- |
+| 网站域名 | `http://admin.pichost.test:3000` |
+| 图片域名 | `http://pic.pichost.test:3000` |
+
+**后台请始终用网站域名打开**，不要用 `localhost`（Cookie 与 Host 不一致）。
+
+### 4. 预期结果
+
+| 地址 | 预期 |
+| ---- | ---- |
+| `http://admin.pichost.test:3000/` | 正常进入后台 |
+| `http://admin.pichost.test:3000/images/...` 或 `/2026/08/xxx.webp` | **404**（请用图片域直链） |
+| `http://pic.pichost.test:3000/` | **404**（正常，图片域不提供后台） |
+| `http://pic.pichost.test:3000/images/...` | 能出图 |
+| `http://localhost:3000/` 或 `http://127.0.0.1:3000/` | **能打开后台**（第三 Host，隔离不生效；仅开发可接受，生产须用反代封禁） |
+
+上传一张图后，复制链接应指向 `pic.pichost.test` 域名；在后台图库中缩略图也应能正常显示。
+
+## 相关说明
+
+- 两个域名 **主机名不能相同**（可同机、不同子域）
+- 设置里的网站域 / 图片域须与反代 `server_name` **完全一致**（含是否带 `www`）
+- 图片域无需单独部署静态目录；与 EasyImages 等不同，PicHost 在应用内完成隔离
+- 单域名部署可不启用分离，仅配置 `IMAGE_BASE_URL` 或使用默认当前访问域名
+- 配置了 Referer 防盗链时，网站域与图片域会自动加入白名单，无需手写两个域名

+# 常见问题
+
+## 忘记管理员密码怎么办？
+
+能执行 `docker exec` 时：
+
+```bash
+docker exec pichost reset-password
+# 或指定用户名
+docker exec pichost reset-password 用户名
+```
+
+本地：`npm run reset-password`。详见 [快速开始](./getting-started.md#忘记密码)。
+
+## 为什么后台无法重新生成 API Token？
+
+若设置了环境变量 `API_UPLOAD_TOKEN`，Token 由环境变量 **锁定**，需修改 env 并 **重启服务**。见 [环境变量](./configuration.md#api-upload-token)。
+
+## 图片外链显示「盗链」或无法加载？
+
+检查 **防盗链白名单**（`ALLOWED_REFERER_HOSTS` 或设置页）。引用图片的站点域名需在白名单中；PicHost 自身域名与双域名场景下的网站域、图片域会自动放行。
+
+## 双域名下为什么用 pages.dev / workers.dev / IP 也能进后台？
+
+PicHost 双域名隔离**只对已配置的网站域、图片域做路径分流**；其它 Host（`localhost`、公网 IP、Cloudflare Pages 的 `*.pages.dev`、Workers 的 `*.workers.dev` 等）**当前不会拦截**，因此可能出现「奇怪地址也能开后台」。
+
+常见原因：在橙云之外又用 **Pages/Workers 整站反代** 到源站，或源站未限制 `server_name` / 允许裸 IP 访问。
+
+处理：仅用正式两个域名访问；反代加 default server；橙云时源站只放行 CF IP。详见 [双域名分离 · 安全与注意事项](./domain-separation.md#安全与注意事项)。
+
+## 能把 PicHost 部署到 Cloudflare Workers / Pages 吗？
+
+**不能（现状）。** 项目使用 `node-server`、SQLite、`sharp` 与本地 `data/`，需 Docker / VPS。CF 控制台「从 Git 创建 Worker」连本仓库会部署失败。
+
+推荐：源站跑 PicHost，CF 用 **橙云 DNS**（含优选）+ 可选 **R2 存储**；不要用 Pages/Workers 反代整站。
+
+## 双域名下后台能打开但缩略图裂图？
+
+- 确认 **图片域名** 配置正确且反代到同一实例
+- 后台请用 **网站域名** 打开，不要用 `localhost` 混用
+- 见 [双域名分离](./domain-separation.md)
+
+## 升级 v1.2 后图库有删不掉的记录？
+
+可能是 **孤儿索引**（有记录无文件）。重启后启动同步会自动清理；也可手动删除仅索引项。见 [v1.2 迁移](./migration.md#第二步启动时自动同步索引)。
+
+## 遗留 `data/blog/` 目录还要吗？
+
+执行 `migrate --apply` 后文件已迁入 `data/images/blog/`。若原目录只剩空壳或非图片文件，可自行备份后删除；迁移脚本不会删除仍含非图片文件的目录。
+
+## 只用对象存储需要跑 migrate 吗？
+
+不需要。图片在桶内时跳过 CLI；启动同步主要面向本地 `data/images/` 磁盘扫描。
+
+## 如何替换博客里的旧图片 URL？
+
+使用 `data/mapping.json`（`migrate` 预览时生成）批量替换旧 key。注意映射的是 **存储 key**，不是完整旧站 URL。见 [迁移指南](./migration.md#外链与直链)。
+
+## 开发时如何跳过登录？
+
+`DEV_BYPASS_ACCESS=true`（仅本地，勿用于生产）。正常流程请访问 `/setup` 创建管理员。

+# v1.2.0 本地磁盘迁移指南
+
+v1.2.0 起，**所有本地图片文件**统一放在 `data/images/` 下；SQLite `images` 表中的 `key` 也以 `images/` 开头。旧版在 `data/blog/`、`data/twikoo/` 等与 `images` **并列的顶层目录**不再符合新模型。
+
+迁移分 **两步**：先用手动 CLI **搬文件**，再由服务 **启动时自动同步索引**。
+
+---
+
+## 从其它图床迁入（EasyImage / 兰空 / Chevereto 等）
+
+**没有**单独的「一键从外链拉取」或「对接某某图床 API」工具。从 **PicHost 旧版** 或其它自托管图床迁入，走的是同一套 **本地文件迁移**：
+
+1. 在旧图床服务器上找到图片**物理目录**（整目录拷贝，不要只拷数据库）。
+2. 把该目录放到 PicHost 的 `data/` 下，作为与 `images` **并列的顶层文件夹**（文件夹名任意，会保留为 `images/{文件夹名}/...`）。
+3. 执行 `migrate` / `migrate --apply`，再重启 PicHost。
+
+### 常见来源示例
+
+| 来源 | 典型图片目录（在旧服务器上） | 放入 PicHost 后示例 |
+| ---- | ---------------------------- | ------------------- |
+| PicHost v1.1.x | `data/blog/`、`data/twikoo/` | 已在 `data/` 下，直接 `migrate` |
+| EasyImage / EasyImages | `i/` 或安装目录下的 `upload/` | 拷到 `data/easyimage/` 再 `migrate` |
+| 兰空图床 (Lsky) | `public/uploads/` 等 | 拷到 `data/lsky/` 再 `migrate` |
+| Chevereto 等 | `images/` 或 `content/` | 拷到 `data/chevereto/` 再 `migrate` |
+| 任意自定义目录 | 你的顶层文件夹名 | 拷到 `data/你的目录名/` 再 `migrate` |
+
+脚本会扫描 `data/` 下**除 `images` 外所有顶层目录**里的图片，不限于 `blog` / `twikoo`。子目录结构会原样保留在 `images/{顶层名}/` 下。
+
+### 操作示例（Docker）
+
+```bash
+# 在宿主机：把从旧图床打包的目录放进挂载卷（名称自定）
+# 例如：./data/easyimage/2026/01/photo.jpg
+
+docker exec pichost migrate          # 预览
+docker exec pichost migrate --apply
+# 重启容器 → 启动日志会补全 SQLite 索引
+```
+
+### 说明与限制
+
+- **只迁移文件**：旧图床的账号、Token、外链 URL **不会**自动导入；`mapping.json` 里的 key 是「旧磁盘相对 key → 新 key」，**不是**旧站完整 URL，替换外链需自行对照。
+- **对象存储**：若旧图床图片在 S3/R2 桶里，请用桶工具同步到本地 `data/某目录/`，或直接在 PicHost **存储**页配置同一桶（不经过本 CLI）。
+- **已直接在 `data/images/` 下**：无需 `migrate`，重启后启动同步会自动建索引。
+
+---
+
+## 存储结构对比
+
+### 迁移前（v1.1.x 常见）
+
+```
+/data
+├── pichost.db
+├── blog/
+│   └── 2026/08/TeKJ2fD6cB6j.webp
+├── twikoo/
+│   └── xxx.webp
+└── images/          # 可能已有部分新图
+    └── ...
+```
+
+SQLite 中 `key` 可能是 `blog/2026/08/TeKJ2fD6cB6j.webp`（与磁盘顶层目录一致）。
+
+### 迁移后（v1.2.0）
+
+```
+/data
+├── pichost.db
+├── mapping.json     # CLI 生成：旧 key → 新 key（供替换外链）
+└── images/
+    ├── blog/
+    │   └── 2026/08/TeKJ2fD6cB6j.webp
+    ├── twikoo/
+    │   └── xxx.webp
+    └── ...            # 新上传：images/随机ID.webp 或 images/年/月/随机ID.webp
+```
+
+对应 `key`：`images/blog/2026/08/TeKJ2fD6cB6j.webp`。
+
+---
+
+## 第一步：CLI 迁移磁盘文件
+
+在 **升级镜像之前或之后**均可执行；建议在升级前完成，并先备份整个 `data/` 目录。
+
+### Docker
+
+```bash
+# 预览：列出待迁移文件，写入 data/mapping.json（旧 key → 新 key）
+docker exec pichost migrate
+
+# 确认无误后执行文件移动
+docker exec pichost migrate --apply
+```
+
+### 本地开发
+
+```bash
+npm run migrate              # 预览
+npm run migrate -- --apply   # 执行
+```
+
+### 脚本行为
+
+| 项目 | 说明 |
+| ---- | ---- |
+| 扫描范围 | `data/` 下**除 `images` 外所有顶层目录**（不限于 blog/twikoo） |
+| 迁移目标 | `data/images/{原顶层目录名}/{相对路径}` |
+| 图片类型 | `.jpg` `.jpeg` `.png` `.webp` `.gif` `.svg` `.ico` |
+| 伴随文件 | 若存在同名的 `.meta.json` 会一并移动 |
+| 非图片文件 | 不移动；若目录内仍有其它文件，**保留原目录**不删除 |
+| 映射表 | `data/mapping.json`，例如 `"blog/foo.webp": "images/blog/foo.webp"` |
+
+脚本路径：`server/cli/migrate-to-single-images.mjs`。
+
+---
+
+## 第二步：启动时自动同步索引
+
+每次 PicHost 启动（`npm run dev`、Docker 容器启动）会自动执行，**无需手动命令**。日志示例：
+
+```text
+[INFO] 开始同步图片索引：扫描本地磁盘 {"path":".../data/images/"}
+[INFO] 磁盘扫描完成：已补全缺失索引 {"inserted":3}
+[INFO] 开始归一化遗留图片路径（如 blog/ → images/blog/）
+[INFO] 遗留路径归一化完成：无需调整
+[INFO] 开始校验索引与磁盘一致性，清理无文件的孤儿记录
+[INFO] 孤儿索引清理完成：未发现孤儿记录
+[INFO] 开始修复存量 Content-Type 元数据
+[INFO] Content-Type 修复完成：无需修复
+[INFO] 图片索引同步结束
+```
+
+| 步骤 | 作用 |
+| ---- | ---- |
+| 扫描 `data/images/` | 磁盘上有、索引里没有 → **补全** `images` 表 |
+| 归一化遗留 key | 将 `blog/...` 等旧 key 更新为 `images/blog/...`（文件已在正确路径时） |
+| 清理孤儿索引 | 索引里有记录、磁盘无文件 → **删除**幽灵记录（避免图库出现删不掉的项） |
+| 修复 Content-Type | 修正错误的 `application/octet-stream` |
+
+CLI 只负责**搬文件**；索引对齐、遗留 key、孤儿记录由启动同步处理。执行 `migrate --apply` 后**重启一次**服务即可。
+
+---
+
+## 推荐升级流程
+
+1. **备份** `data/`（含 `pichost.db` 与各目录）。
+2. `docker exec pichost migrate` 预览，检查输出与 `mapping.json`。
+3. `docker exec pichost migrate --apply` 执行迁移。
+4. 拉取 / 部署 **v1.2.0** 镜像并重启容器。
+5. 查看启动日志，确认「图片索引同步结束」无报错。
+6. 用 `mapping.json` 批量替换博客、Twikoo 等外链中的旧路径（若需要）。
+
+仅使用对象存储、或图片早已全部在 `data/images/` 下时，**跳过第一步**；第二步仍会在启动时运行，通常几秒内完成且无变更日志。

+# 反向代理
+
+生产环境建议通过 Nginx、Caddy、NPM（Nginx Proxy Manager）或 NAS 自带反代，将 HTTPS 流量转发到 PicHost 容器 **6892** 端口。
+
+## 基本要求
+
+- 反代目标：`http://127.0.0.1:6892`（或容器所在主机 IP）
+- 保留请求头：`Host`、`X-Forwarded-Proto`（及常见的 `X-Forwarded-For`）
+- 上传大小：Nginx 建议 `client_max_body_size 12m` 或更大
+- 公网访问请配置 **HTTPS**
+
+## 单域名示例（Nginx）
+
+管理、API、出图同一域名：
+
+```nginx
+server {
+  server_name pic.example.com;
+  location / {
+    proxy_pass http://127.0.0.1:6892;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    client_max_body_size 12m;
+  }
+}
+```
+
+环境变量（可选）：
+
+```env
+IMAGE_BASE_URL=https://pic.example.com
+```
+
+未设置 `IMAGE_BASE_URL` 时，PicHost 会根据反代转发的 `Host` 与 `X-Forwarded-Proto` 推断公网地址。
+
+## 双域名
+
+若后台与图片使用不同域名，两个 `server` 块均可 **全量反代** 到同一端口；隔离由 PicHost 中间件完成。
+
+详见专章：[双域名分离](./domain-separation.md)。
+
+## Cloudflare 橙云
+
+PicHost 应用运行在 **自有服务器 / Docker**（端口 `6892`），Cloudflare 侧推荐：
+
+| 做法 | 说明 |
+| ---- | ---- |
+| **DNS 橙云** | `admin` / `pic` 两个子域 Proxied → 源站反代 `6892`，SSL **Full (strict)** |
+| **DNS 优选** | 与 PicHost 兼容；Host 仍为正式域名 |
+| **R2** | 在存储页作对象后端，非 Pages 托管应用 |
+| **源站防火墙** | 仅放行 [Cloudflare IP](https://www.cloudflare.com/ips/)，禁止公网直连 `6892` |
+
+**不建议：**
+
+- 用 **Cloudflare Pages**（`*.pages.dev`）或 **Workers**（`*.workers.dev`）对 PicHost **整站反代** — 会多出第三 Host，且可能绕过双域名隔离（见 [双域名分离 · 安全与注意事项](./domain-separation.md#安全与注意事项)）
+- 在 CF 控制台「从 Git 创建 Worker」部署本仓库 — 当前为 `node-server` 预设，无法直接 `wrangler deploy`
+
+## 源站安全（双域名推荐）
+
+除 PicHost 中间件外，建议在反代 / 防火墙层加固：
+
+1. **`server_name` 白名单** — 仅网站域与图片域；`default_server` 拒绝裸 IP 与其它 Host
+2. **禁止公网暴露 6892** — 仅本机或内网反代访问；公网只开 80/443
+3. **橙云时限制源站来源 IP** — 仅 Cloudflare 回源 IP 段
+
+双域名场景下 PicHost **不会** 拒绝未配置的 Host；上述措施由运维层补齐。
+
+## Caddy 示例
+
+```caddy
+pic.example.com {
+  reverse_proxy 127.0.0.1:6892
+}
+```
+
+双域名时添加第二个站点块，后端地址相同即可。
+
+## 缓存注意
+
+图片 404/403 与域名隔离 404 响应带 **禁止缓存** 头，避免 CDN 长时间缓存错误页面。若在前端再加 CDN，请对动态 API 路径谨慎缓存。

+# 存储
+
+PicHost 支持 **本地磁盘** 与 **S3 兼容对象存储**（Cloudflare R2、腾讯云 COS、阿里云 OSS、AWS S3 等）。管理员在 **存储**（`/storage`）页管理后端；新上传写入 **默认后端**。
+
+![存储管理](/screenshots/storage.png)
+
+## 存储结构（本地）
+
+```
+/data
+├── pichost.db          # SQLite：用户、会话、设置、storage_backends、images 索引
+└── images/             # 本地后端时的全部图片文件
+```
+
+- 新上传：`images/随机ID.webp` 或 `images/年/月/随机ID.webp`（可在设置中切换扁平模式）
+- 迁移遗留：`images/blog/...` 等子路径
+- 云存储时文件在对应桶内，索引仍在 SQLite `images` 表
+
+所有图片 **key** 以 `images/` 开头。上传 API **不再接受** `folder` 参数。
+
+## 添加存储后端
+
+1. 以管理员登录，打开 **存储** → **添加存储**。
+2. 选择类型：**本地磁盘** 或 **S3 兼容**（含 R2 / COS / OSS 预设）。
+3. 填写连接信息（桶名、Endpoint、Access Key 等）。
+4. 保存后可 **设默认**，新上传将写入该后端。
+
+### Cloudflare R2 要点
+
+| 项 | 值 |
+| -- | -- |
+| Endpoint | `https://<account_id>.r2.cloudflarestorage.com` |
+| Region | `auto` |
+| 桶 | 你的 R2 桶名 |
+| 密钥 | R2 API Token 的 Access Key / Secret Key |
+
+若仓库 **cloudflare** 分支专用于「仅 R2」部署，也可用环境变量预设，见 [文档首页](./index.md) 分支说明。
+
+### 环境变量（可选）
+
+部分部署用环境变量初始化默认 S3 后端（如 `STORAGE_BACKEND=s3`、`S3_ENDPOINT`、`S3_BUCKET`、`S3_ACCESS_KEY`、`S3_SECRET_KEY`、`S3_REGION`）。**UI 中配置的后端信息存于 SQLite**，与环境变量并存时以管理界面为准管理多后端。
+
+## 直链模式
+
+每个后端可配置公开 URL 行为：
+
+| 模式 | 说明 |
+| ---- | ---- |
+| **proxy** | 通过 PicHost 同源代理出图（`GET /images/...`） |
+| **public** | 302 重定向到桶/CDN 公网地址 |
+
+复制链接时使用 **图片域名**（`IMAGE_BASE_URL`）拼接路径。开启「隐藏 images 前缀」后 URL 可能更短，服务按文件名或路径反查索引。
+
+## 用量与筛选
+
+- 存储页展示各后端用量（本地扫描目录，对象存储查询 API）
+- 图库可按存储后端筛选（管理员）
+
+## 备份
+
+请同时备份：
+
+- `data/images/`（本地后端）
+- `data/pichost.db`
+- 各云桶中的对象
+
+从 v1.1.x 升级且存在 `data/blog/` 等并列目录时，见 [v1.2 迁移](./migration.md)。
+
+## 相关

+# Twikoo
+
+PicHost 兼容 **Twikoo** 与 **EasyImage 2.0** 图片上传协议，评论系统可像接 EasyImage 一样配置。
+
+## Twikoo 配置
+
+在 Twikoo 环境变量或配置中设置：
+
+| 配置项 | 值 |
+| ------ | -- |
+| `IMAGE_CDN` | `easyimage` |
+| `IMAGE_CDN_URL` | `https://你的域名/api/index.php` |
+| `IMAGE_CDN_TOKEN` | 与全局 `API_UPLOAD_TOKEN` 相同 |
+
+- 使用 **网站域名**（管理后台域）作为 `IMAGE_CDN_URL` 的主机名
+- Token 需在 PicHost **API** 页生成，或通过 `API_UPLOAD_TOKEN` 环境变量设置
+
+## 上传接口
+
+`POST /api/index.php`
+
+表单字段：
+
+| 字段 | 说明 |
+| ---- | ---- |
+| `image` | 图片文件 |
+| `token` | 全局 API Token（与 `Auth-Token` 等效） |
+
+```bash
+curl -X POST "https://admin.example.com/api/index.php" \
+  -F "token=YOUR_TOKEN" \
+  -F "image=@./demo.png"
+```
+
+上传的图片存入 `images/` 目录，归属与 **全局 Token** 相同（管理员）。
+
+## 与 REST API 的区别
+
+| 项目 | REST `/api/images/upload` | Twikoo `/api/index.php` |
+| ---- | ------------------------- | ------------------------ |
+| 鉴权 | `Auth-Token` 请求头 | 表单 `token` |
+| 响应格式 | PicHost JSON | EasyImage 兼容 JSON |
+| Token | 全局或个人 | 仅全局 Token |
+
+## 双域名部署
+
+Twikoo 上传应走 **网站域名**（`SITE_BASE_URL`），图片展示走 **图片域名**（`IMAGE_BASE_URL`）。详见 [双域名分离](./domain-separation.md)。

+# 用户与权限
+
+PicHost 使用基于角色的访问控制（RBAC）：**管理员（admin）** 与 **普通用户（user）**。权限在服务端强制，不可仅靠前端绕过。
+
+## 角色能力
+
+| 能力 | 管理员 | 普通用户 |
+| ---- | :----: | :------: |
+| 上传图片 | ✓ | ✓ |
+| 查看自己的图库 | ✓ | ✓ |
+| 查看全部图库 / 上传者标签 | ✓ | — |
+| 存储后端管理（`/storage`） | ✓ | — |
+| 系统设置（`/settings`） | ✓ | — |
+| 开放注册开关 | ✓ | — |
+| 全局 API Token 管理 | ✓ | — |
+| 个人 API Token | ✓ | ✓ |
+| 统计页（含注册用户数） | ✓ | 部分 |
+| 操作日志 | ✓ | — |
+
+普通用户顶栏：**API**、**统计**；用户菜单：**修改密码**、**退出登录**。
+
+## 鉴权场景
+
+| 场景 | 鉴权方式 | 图片归属 / 可见范围 |
+| ---- | -------- | ------------------- |
+| 网页上传 | Session Cookie | 当前登录用户 |
+| API 上传 + **个人 Token** | `Auth-Token` 头 | Token 所属用户 |
+| API 上传 + **全局 Token** | `Auth-Token` 头 | 管理员（`userId` 为空） |
+| Twikoo `POST /api/index.php` | 表单 `token` | 与全局 Token 相同 |
+| 图库列表 / 搜索 / 删除 | Session 或 Token | 普通用户仅自己；管理员全部 |
+| 图片直链 `GET /images/...` | 无（Referer 防盗链） | 知道 URL 即可访问 |
+
+## 注册与账号
+
+- 默认仅管理员可创建用户；管理员可在设置中 **开放注册**
+- 密码使用 scrypt 哈希存储
+- Web 登录需先完成滑动拼图验证（拖动滑块对齐缺口）
+- 登录失败有速率限制
+
+## 上传偏好与自动删除
+
+- **上传偏好**（首页卡片翻转）：客户端预压缩、自动复制链接等，按用户保存
+- **自动删除**：管理员可设全局策略；用户可设个人策略。启用后仅影响 **之后新上传** 的图片
+
+## API Token 说明
+
+| 类型 | 谁管理 | 上传归属 | 典型用途 |
+| ---- | ------ | -------- | -------- |
+| **全局 Token** | 管理员（API 页） | 管理员账号 | Twikoo、站点级脚本 |
+| **个人 Token** | 各用户（API 页） | 该用户 | 个人博客、私有脚本 |
+
+若设置了环境变量 `API_UPLOAD_TOKEN`，则全局 Token 被锁定，见 [环境变量](./configuration.md)。
