build_models_url returns /models (no /v1 prefix) for non-local generic
OpenAI-compatible hosts (intentional, see endpoint_resolver.py:206). The
tests added in #4272 expected /v1/models, which is the local/deepseek
behavior. Match production semantics.

+# Pull Request Review Template
+
+Use this shape as a copyable reference for substantive PR reviews; GitHub does
+not auto-apply this file to review comments. Omit sections that do not add
+useful signal. Lead with confirmed findings; keep speculative notes out of the
+public review unless they are framed as a concrete open question.
+
+## Small PR Path
+
+For narrow docs, typo, test-only, or obvious local fixes, a short review is
+enough:
+
+```md
+LGTM after checking:
+- scope:
+- validation:
+- residual risk:
+```
+
+Use the fuller structure below for larger, risky, multi-finding, or
+security-sensitive reviews.
+
+## Findings
+
+**<sub><sub>![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)</sub></sub> issue (test): Short issue title**
+
+- **Problem:** Concrete broken flow, contract, input, or risk.
+
+- **Impact:** Why this matters to users, CI, maintainers, data, security, or scale.
+
+- **Ask:** Smallest practical correction or decision the author should make.
+
+- **Location:** `path:line`
+
+## Open Questions
+
+- **question (scope, non-blocking): Short author question** Ask the concrete
+  intent, scope, or tradeoff question.
+
+## Validation
+
+- Ran:
+- Not run:
+- Residual risk:
+
+## PR Hygiene

+
+## Validation
+
+- Ran:
+- Not run:
+- Residual risk:
+```
+
+## Legend
+
+- **Findings:** Verified, author-actionable issues that should be fixed or
+  consciously accepted before merge.
+- **Priority badges:** The shields.io badges below are optional formatting for
+  priority labels. Plain `P0`, `P1`, `P2`, or `P3` text is also acceptable when
+  an external image dependency is undesirable or may not render.
+  - **P0:** `![P0 Badge](https://img.shields.io/badge/P0-red?style=flat)` -
+    release-blocking or actively dangerous.
+  - **P1:** `![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)` -
+    serious bug, security risk, data-loss risk, or broken primary flow.
+  - **P2:** `![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)` -
+    meaningful correctness, test, maintainability, or edge-case issue.
+  - **P3:** `![P3 Badge](https://img.shields.io/badge/P3-lightgrey?style=flat)` -
+    minor polish or low-risk cleanup.
+- **Intent labels:**
+  - **`issue`:** A confirmed defect, regression, broken contract, or concrete
+    risk.
+  - **`suggestion`:** A non-blocking improvement that would make the PR clearer,
+    safer, or easier to maintain.
+  - **`nit`:** A tiny, non-blocking cleanup or style note. Use it only when the
+    author can safely ignore it without changing the review outcome.
+  - **`question`:** A real author-facing clarification about intent, scope, or
+    tradeoffs. Do not use questions to hide an issue that should be stated
+    directly.
+  - **`LGTM`:** "Looks good to me." Use only when the review found no blocking
+    issues, or when any remaining notes are clearly optional.
+- **Decorations:** Optional labels in parentheses that clarify the finding type,
+  scope, or merge impact.
+  - **`security`:** Auth, authorization, ownership, secrets, SSRF, injection,
+    unsafe external input, or other trust-boundary concerns.
+  - **`test`:** Missing, failing, misleading, brittle, or insufficient tests.
+  - **`scope`:** PR scope, feature boundaries, unrelated churn, or work that
+    should be split into a separate issue or PR.
+  - **`ci`:** CI configuration, workflow failures, flaky checks, or validation
+    signal quality.
+  - **`api`:** Route, request/response, public function, schema, persistence, or
+    integration contract changes.
+  - **`docs`:** User-facing docs, contributor docs, examples, or comments that
+    need to change with the code.
+  - **`non-blocking`:** Useful feedback that should not prevent merge by
+    itself.
+- **Finding fields:**
+  - **Problem:** What is wrong, what contract is ambiguous, or what risk the PR
+    introduces.
+  - **Impact:** Why the problem matters in practical terms.
+  - **Ask:** The smallest concrete fix, test, or decision requested from the PR
+    author.
+  - **Location:** The most useful repo-relative file and line reference for the
+    finding, using `path:line`.
+- **Optional sections:**
+  - **Open Questions:** Genuine scope or intent questions; omit when there are
+    no real questions.
+  - **Validation:** What the reviewer ran, what was intentionally not run, and
+    what risk remains after review.
+  - **PR Hygiene:** Target-branch, template, CI/check, duplicate, related-work,
+    or superseding-PR notes.
+- **`none confirmed`:** Use only when no review-worthy findings were confirmed;
+  still list validation gaps or residual risk when relevant.

+The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
+
+The licenses for most software and other practical works are designed to take away your freedom to share and change the works.  By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
+
+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.
+
+Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
+
+A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate.  Many developers of free software are heartened and encouraged by the resulting cooperation.  However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
+
+The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community.  It requires the operator of a network server to provide the source code of the modified version running there to the users of that server.  Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
+
+An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals.  This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
+
+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 Affero 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. Remote Network Interaction; Use with the GNU General Public License.
+
+Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software.  This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
+
+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 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 work with which it is combined will remain governed by version 3 of the GNU General Public License.
+
+14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the GNU Affero 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 Affero 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 Affero 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 Affero 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.
+
+     <one line to give the program's name and a brief idea of what it does.>
+     Copyright (C) <year>  <name of author>
+
+     This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
+
+     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 Affero General Public License for more details.
+
+     You should have received a copy of the GNU Affero General Public License along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source.  For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code.  There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
+
+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 AGPL, see <http://www.gnu.org/licenses/>.

 ## Quick Start
 
-Defaults work out of the box: clone, run, then configure models/search/email
-inside **Settings**. Only edit `.env` for deployment-level overrides like
-`APP_BIND`, `APP_PORT`, `AUTH_ENABLED`, `DATABASE_URL`, or a pre-seeded admin password.
+> `dev` is the default branch and gets the newest changes first. Use [`main`](https://github.com/pewdiepie-archdaemon/odysseus/tree/main) if you want the more curated branch.
 
-On first setup, Odysseus creates an admin account (`admin` unless
-`ODYSSEUS_ADMIN_USER` is set) and prints a temporary password in the terminal.
-For Docker installs, the same line is in `docker compose logs odysseus`.
-Use that for the first login, then change it in **Settings**.
-
-Contributing? See [CONTRIBUTING.md](CONTRIBUTING.md) for setup, testing, and
-pull request guidelines.
-
-### Docker (recommended)
 ```bash
 git clone https://github.com/pewdiepie-archdaemon/odysseus.git
 cd odysseus
-cp .env.example .env       # optional, but recommended for explicit defaults
+cp .env.example .env
 docker compose up -d --build
 ```
-To include optional extras in the image (PDF viewer, Office extraction; includes AGPL PyMuPDF), build with `docker compose build --build-arg INSTALL_OPTIONAL=true` before `up`.
 
-Open `http://localhost:7000` when the containers are healthy. Docker Compose
-binds the web UI to `127.0.0.1` by default. If the port is taken, set
-`APP_PORT=7001` in `.env` and recreate the container. Set `APP_BIND=0.0.0.0`
-only when you intentionally want LAN/reverse-proxy access.
+Open `http://localhost:7000` when the containers are healthy. The first admin password is printed in `docker compose logs odysseus`.
 
-### Native Linux / macOS
-```bash
-git clone https://github.com/pewdiepie-archdaemon/odysseus.git
-cd odysseus
-python3 -m venv venv
-source venv/bin/activate
-pip install -r requirements.txt
-python setup.py
-python -m uvicorn app:app --host 127.0.0.1 --port 7000
-```
-Requirements: Python 3.11+. Cookbook also needs `tmux` for background model
-downloads and serves. The app itself is lightweight; local model serving is the
-heavy part and depends on the model, runtime, GPU, and VRAM, so small hosts can
-connect to API or remote model servers instead. Use `--host 0.0.0.0` only when you intentionally want LAN/reverse-proxy access.
+Native installs, GPU notes, Windows/macOS instructions, HTTPS, and configuration live in the [setup guide](docs/setup.md).
 
-### Apple Silicon
-Docker on macOS cannot use the Metal GPU. For GPU-accelerated Cookbook on an
-M-series Mac, run Odysseus natively:
+## Features

-It launches at `http://127.0.0.1:7860`. To expose it to your phone over a trusted LAN/VPN such as Tailscale, bind all interfaces:
+## Demo
 
-```bash
-ODYSSEUS_HOST=0.0.0.0 ./start-macos.sh
-# then open http://<tailscale-ip>:7860
-```
-
-The script also reads `.env` at startup, so `APP_BIND=0.0.0.0` and `APP_PORT`
-set there are picked up automatically without a command-line override each run.
-
-Keep `AUTH_ENABLED=true` (the default) before binding outside loopback. Do not
-expose this port directly to the public internet. To build a clickable app wrapper:
-
-```bash
-./build-macos-app.sh
-```
-
-<details>
-<summary>Cookbook, GPU, Ollama, and troubleshooting notes</summary>
-
-**Docker bundled services.** Compose starts Odysseus, ChromaDB, SearXNG, and
-ntfy. Odysseus and the bundled service ports bind to `127.0.0.1` by default, so
-they are reachable from the host but not exposed to your LAN/public internet
-unless you opt in.
-
-**Cookbook storage in Docker.** Downloads live in `./data/huggingface`
-(`~/.cache/huggingface` in the container). Cookbook-installed Python CLIs and
-serve engines live in `./data/local` (`~/.local` in the container), so they
-survive container recreation.
-
-**Remote servers.** In **Cookbook -> Settings -> Servers**, generate the
-Odysseus SSH key and add the public key to the remote server's
-`~/.ssh/authorized_keys`. From the host you can also run:
-
-```bash
-ssh-copy-id -i data/ssh/id_ed25519.pub user@server
-```
-
-**Docker GPU overlays.** CPU-only users can skip this section. Cookbook can
-only detect GPUs that Docker exposes to the container — if the host runtime or
-device passthrough is not configured, Cookbook sees the iGPU, another card, or
-CPU instead of your intended GPU.
-
-For NVIDIA, `scripts/check-docker-gpu.sh` diagnoses GPU passthrough and can
-optionally install the host runtime or update `.env`.
-
-```bash
-# Read-only diagnostic (default — installs nothing, never edits .env):
-scripts/check-docker-gpu.sh
-
-# Print OS-specific install commands without running them:
-scripts/check-docker-gpu.sh --print-install-commands
-
-# Install NVIDIA Container Toolkit on Ubuntu/Debian (requires sudo):
-scripts/check-docker-gpu.sh --install-nvidia-toolkit
-
-# Write COMPOSE_FILE to .env (only when GPU passthrough is confirmed working):
-scripts/check-docker-gpu.sh --enable-nvidia-overlay
-
-# Full assisted setup — install toolkit, then enable overlay if passthrough works:
-scripts/check-docker-gpu.sh --install-nvidia-toolkit --enable-nvidia-overlay
-```
-
-Safety notes:
-- The app never installs host GPU runtime automatically.
-- The app never edits `.env` automatically.
-- `.env` is only modified when `--enable-nvidia-overlay` is explicitly passed,
-  and only after GPU passthrough succeeds. `--yes` skips prompts but does not
-  bypass the passthrough gate.
-- `.env.bak.*` backups created by `--enable-nvidia-overlay` are ignored by
-  Git and the Docker build context.
-
-To enable manually without the script, add this to `.env`:
-
-```bash
-COMPOSE_FILE=docker-compose.yml:docker/gpu.nvidia.yml
-```
-
-**AMD / ROCm.** AMD setup is read-only diagnostic plus manual `.env` edit. Run:
-
-```bash
-scripts/check-docker-amd-gpu.sh
-```
-
-Then add the reported values to `.env`, replacing `RENDER_GID` with your host's
-numeric render group id:
-
-```bash
-COMPOSE_FILE=docker-compose.yml:docker/gpu.amd.yml
-RENDER_GID=989
-```
-
-For NVIDIA/AMD GPU support, also read the comments in the selected overlay file: docker/gpu.nvidia.yml or docker/gpu.amd.yml.
-
-**Stack-management UIs (Portainer, Coolify, Dockhand, etc.).** These tools
-often accept only a single Compose file and do not reliably honor `COMPOSE_FILE`
-or multiple `-f` overlays. CLI users should keep using the `COMPOSE_FILE`
-overlay workflow above. For stack UIs, point the stack at one of the standalone
-files instead, which bundle the base stack plus the GPU settings:
-
-- `docker-compose.gpu-nvidia.yml` — still requires the NVIDIA Container Toolkit
-  on the host.
-- `docker-compose.gpu-amd.yml` — still requires host ROCm/kfd/DRI setup, the
-  `video`/`render` group membership, and `RENDER_GID` when needed.
-
-The base `docker-compose.yml` plus the `docker/gpu.*.yml` overlays remain the
-source of truth; the standalone files mirror them for single-file deployments.
-
-Verify after enabling either overlay:
-
-```bash
-docker compose exec odysseus nvidia-smi -L   # NVIDIA
-docker compose exec odysseus sh -lc 'test -e /dev/kfd && test -d /dev/dri && ls -l /dev/kfd /dev/dri/renderD*'  # AMD
-```
-
-> **GPU passthrough ≠ llama.cpp CUDA.** `nvidia-smi` passing inside the
-> container confirms Docker GPU access, but llama.cpp also needs `cudart` and
-> the CUDA Toolkit at runtime. If Cookbook logs show `Unable to find cudart
-> library`, `Could NOT find CUDAToolkit`, `CUDA Toolkit not found`, or
-> tensors/layers assigned to CPU, that is a Cookbook/llama.cpp build issue —
-> not a Docker passthrough failure. Re-install the serve engine via
-> **Cookbook → Dependencies** to get a CUDA-enabled build.
->
-> The same split applies to AMD/ROCm: seeing `/dev/kfd` and `/dev/dri` inside
-> the container confirms device passthrough, not ROCm userspace or a
-> ROCm-enabled vLLM/llama.cpp build. `rocm-smi` and `rocminfo` are not expected
-> inside the slim Odysseus image.
-
-**Ollama with Docker.** If Ollama runs on the host, add this endpoint in
-Settings:
-
-```text
-http://host.docker.internal:11434/v1
-```
-
-Ollama must listen outside its own loopback interface:
-
-```bash
-OLLAMA_HOST=0.0.0.0:11434 ollama serve
-```
-
-This connects Odysseus in Docker to an Ollama server that is already running on
-your host machine; it does not start Ollama inside the container.
-`host.docker.internal` is Docker's hostname for the host machine from inside the
-container. Cookbook **Serve** is a separate workflow for serving downloaded
-models through Odysseus/llama.cpp, so Windows users with an existing Ollama
-install usually only need to add the endpoint in Settings.
-
-**Useful checks.**
-
-```bash
-docker compose ps
-docker compose logs --tail=120 odysseus
-docker compose logs odysseus | grep -E 'ChromaDB|MemoryVectorStore|DEGRADED'
-```
-
-**macOS details.** `start-macos.sh` installs Homebrew deps, creates the venv,
-runs setup, and starts uvicorn on port `7860` because AirPlay often holds
-`7000`. It uses llama.cpp/Ollama for Metal. vLLM/SGLang are CUDA/ROCm-only and
-do not run on macOS. MLX-only models are not served by Odysseus.
-
-</details>
-
-### Native Windows
-
-**One-command launcher** (creates the venv, installs deps, runs setup, starts the
-server; safe to re-run):
-
-```powershell
-git clone https://github.com/pewdiepie-archdaemon/odysseus.git
-cd odysseus
-powershell -ExecutionPolicy Bypass -File .\launch-windows.ps1
-```
-
-Or do it by hand:
-
-```powershell
-git clone https://github.com/pewdiepie-archdaemon/odysseus.git
-cd odysseus
-py -3.11 -m venv venv
-venv\Scripts\Activate.ps1
-pip install -r requirements.txt
-python setup.py
-python -m uvicorn app:app --host 127.0.0.1 --port 7000
-```
-
-If `python` points at an older interpreter, use `py -3.12` (or another installed
-3.11+ version) for the venv step.
-
-**Requirements:** Python 3.11+. The core app (chat, agent, memory, documents,
-email, calendar, deep research) runs fully native. For full **Cookbook** background
-model downloads and the agent shell tool, also install
-[Git for Windows](https://git-scm.com/download/win) (provides `bash.exe`).
-Local GPU *serving* of vLLM/SGLang needs Linux/WSL2; for a local model on Windows,
-[Ollama](https://ollama.com/download) is the easiest path — point Odysseus at
-`http://localhost:11434/v1` in Settings.
-
-Open `http://localhost:7000`, log in with the generated admin password,
-and configure everything else inside **Settings**.
-
-## Troubleshooting & Advanced Setup
-
-### `chromadb-client` conflicts with embedded ChromaDB
-If `chromadb-client` (the lightweight HTTP-only package) is installed alongside the full `chromadb` package, Odysseus starts but ChromaDB silently falls back to HTTP-only mode and fails.
-
-**Fix:** uninstall `chromadb-client` and force-reinstall the full package:
-```bash
-./venv/bin/pip uninstall chromadb-client -y
-./venv/bin/pip install --force-reinstall chromadb
-```
-
-### HTTPS + LAN/Tailscale exposure
-To expose Odysseus on a local network or Tailscale with HTTPS:
-1. Change the bind address to `0.0.0.0` in `.env` (`APP_BIND=0.0.0.0` or `ODYSSEUS_HOST=0.0.0.0`).
-2. Generate a locally-trusted cert for your LAN/Tailscale IPs using [mkcert](https://github.com/FiloSottile/mkcert):
-   ```bash
-   mkcert -install
-   mkcert -cert-file cert.pem -key-file key.pem 192.168.1.100 tailscale-ip
-   ```
-3. Run `uvicorn` with the generated certs:
-   ```bash
-   python -m uvicorn app:app --host 0.0.0.0 --port 7000 --ssl-certfile=cert.pem --ssl-keyfile=key.pem
-   ```
-4. Install the `mkcert` CA on any other device you want to access Odysseus from (e.g., for iOS, email the `rootCA.pem` to yourself, install the profile, and trust it in Certificate Trust Settings).
-
-### Optional Dependencies
-`requirements-optional.txt` contains packages that unlock extra features. It is not installed by default.
-
-| Package | Feature unlocked |
-|---------|-----------------|
-| `faster-whisper` | Local speech-to-text (microphone -> text) via the "local" STT provider. |
-| `duckduckgo-search` | DuckDuckGo as a search provider option. |
-| `PyMuPDF` | PDF page rendering in the side viewer panel and form-filling. (Note: AGPL-3.0) |
-| `markitdown` | Office/EPUB document text extraction (converts .docx/.xlsx/.pptx/.xls/.epub to Markdown). |
-
-### Outlook / Office 365 email
-Odysseus email accounts currently use IMAP/SMTP username-password auth. Outlook
-and Microsoft 365 generally require OAuth instead, so normal Microsoft mailbox
-passwords will fail. See [docs/email-outlook.md](docs/email-outlook.md) for the
-current limitation and the planned integration direction.
-
-## Security Notes
-Odysseus is a self-hosted workspace with powerful local tools: shell access, file uploads, model downloads, web research, email/calendar integrations, and API tokens. Treat it like an admin console.
-
-- Keep `AUTH_ENABLED=true` for any network-accessible deployment.
-- Keep `LOCALHOST_BYPASS=false` outside local development.
-- Use `SECURE_COOKIES=true` when Odysseus is served through HTTPS by a trusted reverse proxy or private access gateway.
-- Do not expose it directly to the public internet without HTTPS and a trusted reverse proxy or private access layer.
-- Keep `.env`, `data/`, `logs/`, databases, uploads, generated media, backups, auth/session files, API keys, and model/provider tokens out of Git and private shares. They are ignored by default.
-- Review `data/auth.json` after first boot: disable open signup unless you intentionally want it, make only your own account admin, and keep demo/test accounts non-admin.
-- Non-admin users do not get shell/Python/file read/write by default, and admin-only routes/tools such as MCP management, API tokens, webhooks, model/cookbook serving, backup/vault, and app settings are admin-gated. Other features are controlled by per-user privileges, so review each user's privileges before exposing a deployment.
-- Rotate any API keys or tokens that were ever pasted into a shared chat, demo, screenshot, or log.
-- If you enable API tokens or webhooks, create separate tokens per integration and delete unused ones.
-- Prefer binding manual development runs to `127.0.0.1`; bind to `0.0.0.0` only when you intentionally want LAN/reverse-proxy access.
-- Keep ChromaDB, SearXNG, ntfy, Ollama, vLLM, llama.cpp, databases, and raw model/provider APIs internal-only. Expose only the authenticated Odysseus web/API entrypoint through your trusted proxy or private access layer.
-- Before publishing a fork, run `git status --short` and confirm no private files from `.env`, `data/`, `logs/`, uploads, backups, or local databases are staged.

-### Private or proxied deployments
-Odysseus serves plain HTTP on its app port. Docker Compose binds Odysseus and the bundled services to `127.0.0.1` by default, so a typical production/private setup is:
-
-1. Keep Odysseus on localhost, for example `127.0.0.1:7000`.
-2. Terminate HTTPS at a trusted reverse proxy or private access gateway.
-3. Put the authenticated Odysseus web/API entrypoint behind that layer.
-4. Keep raw service and model ports internal-only.
-
-Cloudflare Access, Tailscale, Caddy, nginx, and Traefik can all fit this pattern; none are required by Odysseus. If your access layer reaches Odysseus on the same host, proxy to `http://127.0.0.1:7000` and keep `AUTH_ENABLED=true`, `LOCALHOST_BYPASS=false`, and `SECURE_COOKIES=true`.
-
-Common internal-only ports from the default docs/compose setup:
-
-| Port | Service |
-|---|---|
-| `7000` | Odysseus raw app port |
-| `8080` | SearXNG |
-| `8091` | ntfy |
-| `8100` | ChromaDB host port for manual/compose access |
-| `11434` | Ollama |
-| `8000-8020` | Common local model/provider APIs |

+## Security
 
-All upload-limit vars are validated (must be a positive integer) and optional; an invalid value fails fast at startup.
-
-### Built-in MCP servers (optional setup)
-
-Odysseus auto-registers a few built-in MCP servers at startup. The npx-based ones (currently the browser server, `@playwright/mcp`) only start when their npm package is already in the local npx cache. If a package isn't cached, that server is skipped with a startup log message explaining what to do, so a fresh install does not block on a multi-minute npm download or hang if Playwright system deps are missing.
-
-To enable the browser MCP (page navigation, screenshots, vision), run once:
-
-```bash
-npx -y @playwright/mcp@latest --version
-```
-
-That installs `@playwright/mcp` plus Playwright (~300MB total). Restart Odysseus and the server will register at startup.
-

-## Data
-All user data lives in `data/` (gitignored): `app.db` (sessions, messages, documents),
-`memory.json`, `presets.json`, `uploads/`, `personal_docs/`, `chroma/`, `settings.json`.
+Odysseus is a self-hosted workspace with powerful local tools. Keep auth enabled, keep private data out of Git, and do not expose raw model/service ports publicly. Deployment details are in the [setup guide](docs/setup.md#security-notes).

+# Agent migration manifests
+
+Odysseus should be able to learn from another agent without blindly trusting
+that agent's whole state. The safe migration path is:
+
+```text
+source agent export -> source adapter -> agent-migration.v1 manifest -> preview -> apply
+```
+
+The manifest is intentionally source-neutral. OpenClaw, Hermes, a folder of
+Markdown notes, or any other agent can have its own adapter, but Odysseus only
+needs to understand the normalized manifest.
+
+## Why not import everything as memory?
+
+Durable memory should stay compact and useful. Long notes, logs, session
+transcripts, and project archives are useful context, but they are not all
+memories. A good migration keeps two layers separate:
+
+- **Archive documents** preserve source material for search, reading, and later
+  extraction.
+- **Memory candidates** are short facts or preferences that can be reviewed
+  before being saved into Odysseus memory.
+
+This keeps Odysseus' existing memory-review flow intact while giving it better
+source material to review.
+
+## Manifest shape
+
+`agent-migration.v1` is a JSON object:
+
+```json
+{
+  "schema_version": "agent-migration.v1",
+  "generated_at": "2026-06-06T00:00:00Z",
+  "source": {
+    "name": "example-agent",
+    "kind": "generic"
+  },
+  "summary": {
+    "item_count": 3,
+    "counts_by_kind": {
+      "memory": 1,
+      "skill": 1,
+      "conversation_thread": 1,
+      "archive_document": 1
+    },
+    "warning_count": 0
+  },
+  "items": [],
+  "warnings": []
+}
+```
+
+Each item has a stable `id`, a `kind`, source metadata, and enough content for a
+future importer to preview it before applying.
+
+Supported item kinds in the first pass:
+
+- `memory` — a candidate memory with `text`, `category`, `source`, and
+  provenance metadata.
+- `skill` — a `SKILL.md` file with content and parsed frontmatter metadata.
+- `conversation_thread` — a normalized transcript thread from an exported chat
+  history. Message content is optional; adapters can preserve only thread
+  metadata, message counts, timestamps, and hashes when a manifest should stay
+  small or avoid embedding private transcript text.
+- `archive_document` — long-form source material. Content is optional; adapters
+  can preserve only path/hash/size metadata when a manifest should stay small.
+
+## Build a manifest
+
+Use the read-only helper:
+
+```bash
+python3 scripts/agent_migration_manifest.py \
+  --source-name old-agent \
+  --source-kind generic \
+  --memory-json /path/to/memories.json \
+  --skills-dir /path/to/skills \
+  --conversation-json /path/to/conversations.json \
+  --archive /path/to/notes \
+  --output /tmp/agent-migration.json
+```
+
+The helper does not write to `data/`, call an LLM, import Odysseus modules, or
+modify the source. It only writes JSON.
+
+Memory JSON may be:
+
+```json
+[
+  "A plain memory string",
+  {
+    "text": "A categorized memory",
+    "category": "preference",
+    "source": "old-agent"
+  }
+]
+```
+
+or an object containing a list under `memories`, `memory`, `items`, or `data`.
+
+Skills are scanned recursively for `SKILL.md`:
+
+```bash
+python3 scripts/agent_migration_manifest.py \
+  --source-name hermes \
+  --source-kind hermes \
+  --skills-dir ~/.hermes/skills \
+  --output /tmp/hermes-skills-manifest.json
+```
+
+Archive documents are metadata-only by default. To embed text content:
+
+```bash
+python3 scripts/agent_migration_manifest.py \
+  --source-name notes-export \
+  --archive /path/to/markdown-notes \
+  --include-archive-content \
+  --output /tmp/notes-manifest.json
+```
+
+Conversation exports are also metadata-only by default:
+
+```bash
+python3 scripts/agent_migration_manifest.py \
+  --source-name chatgpt-export \
+  --source-kind chatgpt \
+  --conversation-json /path/to/conversations.json \
+  --output /tmp/chatgpt-conversations-manifest.json
+```
+
+The first pass supports generic conversation JSON such as:
+
+```json
+[
+  {
+    "id": "thread-1",
+    "title": "Project plan",
+    "messages": [
+      {"role": "user", "content": "Can we design this?"},
+      {"role": "assistant", "content": "Yes, start with a narrow slice."}
+    ]
+  }
+]
+```
+
+It also recognizes ChatGPT-style `mapping` exports from `conversations.json`.
+To embed normalized messages:
+
+```bash
+python3 scripts/agent_migration_manifest.py \
+  --source-name chatgpt-export \
+  --source-kind chatgpt \
+  --conversation-json /path/to/conversations.json \
+  --include-conversation-content \
+  --max-conversation-messages 2000 \
+  --output /tmp/chatgpt-conversations-with-content.json
+```
+
+Content embedding is explicit because exported chat histories can be huge and
+private. A future source-specific adapter can add ZIP traversal, attachment
+metadata, and provider-specific project/workspace fields while still emitting
+the same `conversation_thread` manifest item.
+
+## Recommended apply behavior
+
+A future Odysseus importer should treat the manifest as untrusted user-provided
+data and apply it in stages:
+
+1. Show a dry-run summary with counts, warnings, duplicates, and sample items.
+2. Back up current `data/` state before writing anything.
+3. Import archive documents as documents or another searchable source, not as
+   memory.
+4. Import conversation threads as searchable archived context first, with
+   citations back to the source thread. Do not turn whole transcripts into
+   memory.
+5. Show memory candidates for review before saving through the normal memory
+   path.
+6. Import skills only after name/category conflict checks.
+7. Skip secrets by default. Credentials need explicit, provider-specific flows.
+
+## What belongs in source adapters?
+
+Adapters can be source-specific. The core manifest should not be.
+
+For example, an OpenClaw adapter may know about OpenClaw's workspace files. A
+Hermes adapter may know about `~/.hermes/config.yaml` and `~/.hermes/skills`.
+A ChatGPT adapter may know about `conversations.json`, uploaded-file metadata,
+and image attachment directories. A Claude adapter may know about Claude's
+export shape and project boundaries. A generic adapter may only know about
+memory JSON, conversation JSON, `SKILL.md`, and Markdown folders.
+
+Nonstandard folders should be adapter details, not required Odysseus concepts.

+# Backup & Restore
+
+Odysseus keeps all of your state in the `data/` directory — the SQLite database
+(`app.db`), the Fernet encryption key (`data/.app_key`), the vault, memory, RAG
+indexes, personal documents, and uploads. The `scripts/odysseus-backup` tool
+snapshots that directory into a single gzip tarball and restores it later.
+
+Snapshots are safe to take while the app is running: SQLite databases are copied
+through SQLite's own `.backup` API rather than a raw file copy, so an in-flight
+write can't corrupt the snapshot.
+
+> **A snapshot contains your secrets.** The tarball includes the Fernet
+> encryption key (`data/.app_key`), the vault, sessions, and any stored
+> provider/API tokens — so treat it like a password. Store backups somewhere
+> private, never commit them to Git, and prefer an encrypted destination when
+> copying them offsite.
+
+## Quick start
+
+Run the tool from the repository root:
+
+```bash
+# Create a snapshot → backups/odysseus-backup-<YYYYMMDD-HHMMSS>.tar.gz
+./scripts/odysseus-backup snapshot
+
+# List existing snapshots (most recent first)
+./scripts/odysseus-backup list
+
+# Check a tarball's integrity without extracting it
+./scripts/odysseus-backup verify backups/odysseus-backup-20260101-120000.tar.gz
+
+# Restore (destructive — see the warning below)
+./scripts/odysseus-backup restore backups/odysseus-backup-20260101-120000.tar.gz --yes
+```
+
+The script depends only on the Python standard library, so any `python3` on your
+`PATH` will run it — you don't need the app's virtualenv active.
+
+Every command prints a JSON result. Add `--pretty` for indented output.
+
+## Commands
+
+### `snapshot`
+
+Writes a `tar.gz` of `data/` to `backups/<timestamp>.tar.gz`.
+
+| Flag | Effect |
+| --- | --- |
+| `--out PATH` | Write to a specific path instead of the default `backups/` location. Must be **outside** `data/`. |
+| `--include-research` | Include `data/deep_research/` (skipped by default — research runs are large). |
+| `--include-attachments` | Include `data/mail-attachments/` (skipped by default — cached IMAP extractions, re-derivable). |
+
+By default the snapshot includes everything under `data/` **except**
+`deep_research/` and `mail-attachments/`. Personal uploads and documents are
+included.
+
+```bash
+# Snapshot straight to a mounted NAS path
+./scripts/odysseus-backup snapshot --out /mnt/nas/odysseus-$(date +%F).tar.gz
+
+# Full snapshot including research runs and mail attachments
+./scripts/odysseus-backup snapshot --include-research --include-attachments
+```
+
+### `list`
+
+Lists the tarballs in `backups/`, most recent first, with size and modification
+time.
+
+### `verify PATH`
+
+Opens the tarball read-only and walks every member to confirm it is intact and
+safe to restore. Nothing is extracted. Use this before relying on an old backup
+or after copying one across machines.
+
+### `restore PATH --yes`
+
+Overwrites `data/` from a tarball.
+
+> **Restore is destructive.** It replaces the current `data/` directory. `--yes`
+> is required so a mistyped command can't wipe your live state.
+
+Restore is not a blind delete: before extracting, the tool **renames your current
+`data/` to `data.before-restore-<timestamp>`** in the repository root. If a
+restore turns out to be wrong, your previous state is still there — delete the
+restored `data/` and rename the stashed directory back. The restore path is also
+validated entry-by-entry: archives containing absolute paths, `..` segments,
+symlinks, or anything outside `data/` are rejected.
+
+## Scheduling offsite backups
+
+The tarball output composes cleanly with cron and any copy tool. For example, a
+nightly snapshot copied offsite:
+
+```cron
+0 3 * * *  cd /path/to/odysseus && ./scripts/odysseus-backup snapshot --out "/mnt/nas/odysseus-$(date +\%F).tar.gz"
+```
+
+Swap the `--out` target for `scp`, `rclone`, `s3cmd`, or similar to push the
+snapshot to remote storage.
+
+## Docker vs native installs
+
+The tool reads `data/` and writes `backups/` relative to the repository root, so
+where you run it matters:
+
+- **Native installs** — run it from the repo root as shown above. `data/` and
+  `backups/` are both in the repo directory.
+- **Docker** — `docker-compose.yml` bind-mounts the host's `./data` to
+  `/app/data`, so the live data is also present on the host. **Run the tool on
+  the host** from the repo root; the snapshot reads the bind-mounted `./data` and
+  writes to `./backups` on the host. Running it *inside* the container is not
+  recommended, because `backups/` is not a mounted volume and the tarball would
+  be lost when the container is recreated.
+
+> **ChromaDB caveat (Docker only).** In the Docker setup, ChromaDB stores its
+> vectors in a separate Compose-managed volume (declared as `chromadb-data`),
+> **not** under `./data`. `odysseus-backup` therefore does not capture the Docker
+> ChromaDB store. Back it up separately if you need it. Compose prefixes the
+> volume with the project name, so find the real name first
+> (`docker volume ls | grep chromadb`), then archive it — for example:
+>
+> ```bash
+> docker run --rm -v <project>_chromadb-data:/data -v "$PWD":/backup \
+>   alpine tar czf /backup/chromadb.tar.gz -C /data .
+> ```
+>
+> On native installs ChromaDB lives at `data/chroma/` and is included in the
+> snapshot normally.

+# Security CI guide
+
+This project runs a set of automated security checks on every pull request and
+on every push to `main`. This page explains what each one does, whether it can
+block a merge, and the few one-time settings you should turn on to get the full
+benefit.
+
+## What runs, and why
+
+Each check lives in its own file under `.github/workflows/`. They run
+automatically; you do not start them.
+
+| Check | What it protects against | Blocks a merge? |
+|---|---|---|
+| **Secret scan** (gitleaks) | An API key, token, or password being committed by mistake or on purpose | Yes |
+| **Workflow security** (actionlint + zizmor) | A broken or insecure automation file that could leak the repo's access token | Yes |
+| **Dependency review** | A pull request that adds a software library with a known security hole | Yes |
+| **pip-audit** | Known security holes in the Python libraries already used | No (advisory) |
+| **Container scan: hadolint** | Mistakes and insecure patterns in the `Dockerfile` | Yes |
+| **Container scan: Trivy** | Known security holes in the Docker image | No (advisory) |
+| **CodeQL** | Real bugs in the app's own code: injection, auth mistakes, path traversal | No (advisory) |
+
+"Blocks a merge" means a red X appears on the pull request and, once you enable
+the setting below, the **Merge** button is disabled until it is fixed.
+
+"Advisory" means it reports problems into the repository's **Security** tab so
+you can review them on your own schedule, but it never stops a merge. These are
+advisory on purpose: they often flag long-standing issues in other people's
+libraries, not something a given pull request introduced.
+
+## Where results appear
+
+- **Checks tab of a pull request**: the pass/fail of each check. A green tick is
+  good; a red X needs attention.
+- **Security tab of the repository**: detailed findings from the advisory
+  scanners (Trivy and CodeQL). This is your dashboard.
+
+## If a check fails
+
+- **Secret scan failed**: a real credential may have been committed. Treat it as
+  leaked: rotate (regenerate) that key or token immediately, then remove it from
+  the file. Do not just delete the commit; assume it was seen.
+- **Dependency review failed**: the pull request adds a library with a known
+  vulnerability. Ask the contributor to use a patched version, or decline the
+  change.
+- **hadolint / workflow security failed**: the contributor changed the
+  `Dockerfile` or an automation file in a way the linter rejects. Ask them to
+  address the message shown in the failed check.
+
+## One-time settings to turn on
+
+These two settings unlock the full value. You only do them once.
+
+### 1. Require the blocking checks before merging
+
+This makes the **Merge** button refuse to work until the gating checks pass.
+
+1. Go to the repository on GitHub.
+2. Click **Settings** (top right of the repo).
+3. In the left sidebar, click **Branches**.
+4. Under **Branch protection rules**, click **Add branch ruleset** (or **Add
+   rule**), and set the branch name pattern to `dev` (this is the branch all
+   pull requests target; `main` is fast-forwarded at releases).
+5. Enable **Require status checks to pass before merging**.
+6. In the search box that appears, add these checks by name:
+   - `Python syntax (compileall)`
+   - `JS syntax (node --check)`
+   - `gitleaks`
+   - `actionlint`
+   - `zizmor (Actions SAST)`
+   - `hadolint (Dockerfile lint)`
+   - `dependency-review (PR gate)`
+
+   The first two come from the correctness CI (`ci.yml`); the rest are this
+   security suite. Leave pytest, pip-audit, Trivy, and CodeQL unchecked so they
+   stay advisory.
+7. Also enable **Require a pull request before merging** and **Require review
+   from Code Owners** (this uses the `.github/CODEOWNERS` file so every change
+   needs your sign-off).
+8. Click **Create** / **Save changes**.
+
+Note: a check name only appears in the list after it has run at least once, so
+let the workflows run on one pull request first, then add them here.
+
+### 2. Turn on the Security tab features
+
+1. **Settings -> Code security** (or **Code security and analysis**).
+2. Turn on **Dependency graph** (usually on by default for public repos) -- this
+   powers Dependency review and Dependabot.
+3. Turn on **Dependabot alerts** and **Dependabot security updates**.
+4. Under **Code scanning**, you have two ways to scan the app code with CodeQL:
+   - The included `codeql.yml` workflow already scans `main` and runs weekly.
+   - To also scan **pull requests** (recommended, since most contributions come
+     from forks), click **Set up -> Default** under Code scanning. GitHub then
+     runs CodeQL on pull requests for you, with no token limitations.
+
+## Keeping it current
+
+`.github/dependabot.yml` opens small weekly pull requests to update Python and
+npm packages, the Docker base image, and the pinned automation actions
+themselves. Review and merge those like any other pull request; they keep the
+project patched without manual tracking.

+# Odysseus Setup Guide
+
+This page keeps the detailed install, deployment, troubleshooting, and configuration notes out of the front README.
+
+## Quick Start
+
+> **Branch note:** `dev` is the default branch and contains the latest development changes, but it may be unstable. For the more stable curated branch, use [`main`](https://github.com/pewdiepie-archdaemon/odysseus/tree/main).
+
+Defaults work out of the box: clone, run, then configure models/search/email
+inside **Settings**. Only edit `.env` for deployment-level overrides like
+`APP_BIND`, `APP_PORT`, `AUTH_ENABLED`, `DATABASE_URL`, or a pre-seeded admin password.
+
+On first setup, Odysseus creates an admin account (`admin` unless
+`ODYSSEUS_ADMIN_USER` is set) and prints a temporary password in the terminal.
+For Docker installs, the same line is in `docker compose logs odysseus`.
+Use that for the first login, then change it in **Settings**.
+
+Contributing? See [CONTRIBUTING.md](CONTRIBUTING.md) for setup, testing, and
+pull request guidelines.
+
+### Docker (recommended)
+```bash
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+cp .env.example .env       # optional, but recommended for explicit defaults
+docker compose up -d --build
+```
+To include optional extras in the image (PDF viewer, Office extraction; includes AGPL PyMuPDF), build with `docker compose build --build-arg INSTALL_OPTIONAL=true` before `up`.
+
+Open `http://localhost:7000` when the containers are healthy. Docker Compose
+binds the web UI to `127.0.0.1` by default. If the port is taken, set
+`APP_PORT=7001` in `.env` and recreate the container. Set `APP_BIND=0.0.0.0`
+only when you intentionally want LAN/reverse-proxy access.
+
+> **On Apple Silicon (M-series) Macs:** Docker can't reach the Metal GPU, so
+> Cookbook serves local models on CPU only. For GPU-accelerated model serving,
+> run natively instead — see [Apple Silicon](#apple-silicon) below.
+
+### Native Linux / macOS
+```bash
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+python3 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+python setup.py
+python -m uvicorn app:app --host 127.0.0.1 --port 7000
+```
+Requirements: Python 3.11+. Cookbook also needs `tmux` for background model
+downloads and serves. The app itself is lightweight; local model serving is the
+heavy part and depends on the model, runtime, GPU, and VRAM, so small hosts can
+connect to API or remote model servers instead. Use `--host 0.0.0.0` only when you intentionally want LAN/reverse-proxy access.
+
+### Apple Silicon
+Docker on macOS cannot use the Metal GPU. For GPU-accelerated Cookbook on an
+M-series Mac, run Odysseus natively:
+
+```bash
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+./start-macos.sh
+```
+
+It launches at `http://127.0.0.1:7860`. To expose it to your phone over a trusted LAN/VPN such as Tailscale, bind all interfaces:
+
+```bash
+ODYSSEUS_HOST=0.0.0.0 ./start-macos.sh
+# then open http://<tailscale-ip>:7860
+```
+
+The script also reads `.env` at startup, so `APP_BIND=0.0.0.0` and `APP_PORT`
+set there are picked up automatically without a command-line override each run.
+
+Keep `AUTH_ENABLED=true` (the default) before binding outside loopback. Do not
+expose this port directly to the public internet. To build a clickable app wrapper:
+
+```bash
+./build-macos-app.sh
+```
+
+<details>
+<summary>Cookbook, GPU, Ollama, and troubleshooting notes</summary>
+
+**Docker bundled services.** Compose starts Odysseus, ChromaDB, SearXNG, and
+ntfy. Odysseus and the bundled service ports bind to `127.0.0.1` by default, so
+they are reachable from the host but not exposed to your LAN/public internet
+unless you opt in.
+
+**Cookbook storage in Docker.** Downloads live in `./data/huggingface`
+(`~/.cache/huggingface` in the container). Cookbook-installed Python CLIs and
+serve engines live in `./data/local` (`~/.local` in the container), so they
+survive container recreation.
+
+**Remote servers.** In **Cookbook -> Settings -> Servers**, generate the
+Odysseus SSH key and add the public key to the remote server's
+`~/.ssh/authorized_keys`. From the host you can also run:
+
+```bash
+ssh-copy-id -i data/ssh/id_ed25519.pub user@server
+```
+
+**Docker GPU overlays.** CPU-only users can skip this section. Cookbook can
+only detect GPUs that Docker exposes to the container — if the host runtime or
+device passthrough is not configured, Cookbook sees the iGPU, another card, or
+CPU instead of your intended GPU.
+
+For NVIDIA, `scripts/check-docker-gpu.sh` diagnoses GPU passthrough and can
+optionally install the host runtime or update `.env`.
+
+```bash
+# Read-only diagnostic (default — installs nothing, never edits .env):
+scripts/check-docker-gpu.sh
+
+# Print OS-specific install commands without running them:
+scripts/check-docker-gpu.sh --print-install-commands
+
+# Install NVIDIA Container Toolkit on Ubuntu/Debian (requires sudo):
+scripts/check-docker-gpu.sh --install-nvidia-toolkit
+
+# Write COMPOSE_FILE to .env (only when GPU passthrough is confirmed working):
+scripts/check-docker-gpu.sh --enable-nvidia-overlay
+
+# Full assisted setup — install toolkit, then enable overlay if passthrough works:
+scripts/check-docker-gpu.sh --install-nvidia-toolkit --enable-nvidia-overlay
+```
+
+Safety notes:
+- The app never installs host GPU runtime automatically.
+- The app never edits `.env` automatically.
+- `.env` is only modified when `--enable-nvidia-overlay` is explicitly passed,
+  and only after GPU passthrough succeeds. `--yes` skips prompts but does not
+  bypass the passthrough gate.
+- `.env.bak.*` backups created by `--enable-nvidia-overlay` are ignored by
+  Git and the Docker build context.
+
+To enable manually without the script, add this to `.env`:
+
+```bash
+COMPOSE_FILE=docker-compose.yml:docker/gpu.nvidia.yml
+```
+
+**AMD / ROCm.** AMD setup is read-only diagnostic plus manual `.env` edit. Run:
+
+```bash
+scripts/check-docker-amd-gpu.sh
+```
+
+Then add the reported values to `.env`, replacing `RENDER_GID` with your host's
+numeric render group id:
+
+```bash
+COMPOSE_FILE=docker-compose.yml:docker/gpu.amd.yml
+RENDER_GID=989
+```
+
+For NVIDIA/AMD GPU support, also read the comments in the selected overlay file: docker/gpu.nvidia.yml or docker/gpu.amd.yml.
+
+**Stack-management UIs (Portainer, Coolify, Dockhand, etc.).** These tools
+often accept only a single Compose file and do not reliably honor `COMPOSE_FILE`
+or multiple `-f` overlays. CLI users should keep using the `COMPOSE_FILE`
+overlay workflow above. For stack UIs, point the stack at one of the standalone
+files instead, which bundle the base stack plus the GPU settings:
+
+- `docker-compose.gpu-nvidia.yml` — still requires the NVIDIA Container Toolkit
+  on the host.
+- `docker-compose.gpu-amd.yml` — still requires host ROCm/kfd/DRI setup, the
+  `video`/`render` group membership, and `RENDER_GID` when needed.
+
+The base `docker-compose.yml` plus the `docker/gpu.*.yml` overlays remain the
+source of truth; the standalone files mirror them for single-file deployments.
+
+Verify after enabling either overlay:
+
+```bash
+docker compose exec odysseus nvidia-smi -L   # NVIDIA
+docker compose exec odysseus sh -lc 'test -e /dev/kfd && test -d /dev/dri && ls -l /dev/kfd /dev/dri/renderD*'  # AMD
+```
+
+> **GPU passthrough ≠ llama.cpp CUDA.** `nvidia-smi` passing inside the
+> container confirms Docker GPU access, but llama.cpp also needs `cudart` and
+> the CUDA Toolkit at runtime. If Cookbook logs show `Unable to find cudart
+> library`, `Could NOT find CUDAToolkit`, `CUDA Toolkit not found`, or
+> tensors/layers assigned to CPU, that is a Cookbook/llama.cpp build issue —
+> not a Docker passthrough failure. Reinstall the serve engine via
+> **Cookbook → Dependencies** to get a CUDA-enabled build.
+>
+> The same split applies to AMD/ROCm: seeing `/dev/kfd` and `/dev/dri` inside
+> the container confirms device passthrough, not ROCm userspace or a
+> ROCm-enabled vLLM/llama.cpp build. `rocm-smi` and `rocminfo` are not expected
+> inside the slim Odysseus image.
+
+**Ollama with Docker.** If Ollama runs on the host, add this endpoint in
+Settings:
+
+```text
+http://host.docker.internal:11434/v1
+```
+
+Ollama must listen outside its own loopback interface:
+
+```bash
+OLLAMA_HOST=0.0.0.0:11434 ollama serve
+```
+
+This connects Odysseus in Docker to an Ollama server that is already running on
+your host machine; it does not start Ollama inside the container.
+`host.docker.internal` is Docker's hostname for the host machine from inside the
+container. Cookbook **Serve** is a separate workflow for serving downloaded
+models through Odysseus/llama.cpp, so Windows users with an existing Ollama
+install usually only need to add the endpoint in Settings.
+
+**Useful checks.**
+
+```bash
+docker compose ps
+docker compose logs --tail=120 odysseus
+docker compose logs odysseus | grep -E 'ChromaDB|MemoryVectorStore|DEGRADED'
+```
+
+**macOS details.** `start-macos.sh` installs Homebrew deps, creates the venv,
+runs setup, and starts uvicorn on port `7860` because AirPlay often holds
+`7000`. It uses llama.cpp/Ollama for Metal. vLLM/SGLang are CUDA/ROCm-only and
+do not run on macOS. MLX-only models are not served by Odysseus.
+
+</details>
+
+### Native Windows
+
+**One-command launcher** (creates the venv, installs deps, runs setup, starts the
+server; safe to re-run):
+
+```powershell
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+powershell -ExecutionPolicy Bypass -File .\launch-windows.ps1
+```
+
+Or do it by hand:
+
+```powershell
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+py -3.11 -m venv venv
+venv\Scripts\Activate.ps1
+pip install -r requirements.txt
+python setup.py
+python -m uvicorn app:app --host 127.0.0.1 --port 7000
+```
+
+If `python` points at an older interpreter, use `py -3.12` (or another installed
+3.11+ version) for the venv step.
+
+**Requirements:** Python 3.11+. The core app (chat, agent, memory, documents,
+email, calendar, deep research) runs fully native. For full **Cookbook** background
+model downloads and the agent shell tool, also install
+[Git for Windows](https://git-scm.com/download/win) (provides `bash.exe`).
+Local GPU *serving* of vLLM/SGLang needs Linux/WSL2; for a local model on Windows,
+[Ollama](https://ollama.com/download) is the easiest path — point Odysseus at
+`http://localhost:11434/v1` in Settings.
+
+Open `http://localhost:7000`, log in with the generated admin password,
+and configure everything else inside **Settings**.
+
+## Troubleshooting & Advanced Setup
+
+### `chromadb-client` conflicts with embedded ChromaDB
+If `chromadb-client` (the lightweight HTTP-only package) is installed alongside the full `chromadb` package, Odysseus starts but ChromaDB silently falls back to HTTP-only mode and fails.
+
+**Fix:** uninstall `chromadb-client` and force-reinstall the full package:
+```bash
+./venv/bin/pip uninstall chromadb-client -y
+./venv/bin/pip install --force-reinstall chromadb
+```
+
+### HTTPS + LAN/Tailscale exposure
+To expose Odysseus on a local network or Tailscale with HTTPS:
+1. Change the bind address to `0.0.0.0` in `.env` (`APP_BIND=0.0.0.0` or `ODYSSEUS_HOST=0.0.0.0`).
+2. Generate a locally-trusted cert for your LAN/Tailscale IPs using [mkcert](https://github.com/FiloSottile/mkcert):
+   ```bash
+   mkcert -install
+   mkcert -cert-file cert.pem -key-file key.pem 192.168.1.100 tailscale-ip
+   ```
+3. Run `uvicorn` with the generated certs:
+   ```bash
+   python -m uvicorn app:app --host 0.0.0.0 --port 7000 --ssl-certfile=cert.pem --ssl-keyfile=key.pem
+   ```
+4. Install the `mkcert` CA on any other device you want to access Odysseus from (e.g., for iOS, email the `rootCA.pem` to yourself, install the profile, and trust it in Certificate Trust Settings).
+
+### Optional Dependencies
+`requirements-optional.txt` contains packages that unlock extra features. It is not installed by default.
+
+| Package | Feature unlocked |
+|---------|-----------------|
+| `faster-whisper` | Local speech-to-text (microphone -> text) via the "local" STT provider. |
+| `ddgs` | DuckDuckGo as a search provider option. |
+| `PyMuPDF` | PDF page rendering in the side viewer panel and form-filling. (Note: AGPL-3.0) |
+| `markitdown` | Office/EPUB document text extraction (converts .docx/.xlsx/.pptx/.xls/.epub to Markdown). |
+
+### Faster, reproducible installs with uv (optional)
+[uv](https://docs.astral.sh/uv/) works as a drop-in replacement for the
+venv + pip steps in the native install guides, no project changes are needed but this change results in faster installs along with a lockfile for reproducible environments. After [installing `uv`](https://docs.astral.sh/uv/getting-started/installation/), use:
+
+```bash
+uv venv venv --python 3.13
+uv pip install -r requirements.txt
+# then continue as usual: python setup.py, uvicorn, ...
+```
+
+`requirements.txt` is intentionally unpinned, so two installs at different times can produce different package versions. If you want a reproducible environment (e.g. across your own machines, or to roll back after a bad upgrade), snapshot and restore exact versions with:
+
+```bash
+uv pip compile requirements.txt -o requirements.lock   # snapshot current resolution
+uv pip sync requirements.lock                          # reproduce it exactly later
+```
+
+`requirements.lock` is gitignored and platform-specific (compile it on the OS you deploy to). Regenerate it deliberately when you want to take upgrades. The plain `uv pip install -r requirements.txt` keeps following the unpinned requirements like pip does.
+
+### Outlook / Office 365 email
+Odysseus email accounts currently use IMAP/SMTP username-password auth. Outlook
+and Microsoft 365 generally require OAuth instead, so normal Microsoft mailbox
+passwords will fail. See [docs/email-outlook.md](docs/email-outlook.md) for the
+current limitation and the planned integration direction.
+
+## Security Notes
+Odysseus is a self-hosted workspace with powerful local tools: shell access, file uploads, model downloads, web research, email/calendar integrations, and API tokens. Treat it like an admin console.
+
+- Keep `AUTH_ENABLED=true` for any network-accessible deployment.
+- Keep `LOCALHOST_BYPASS=false` outside local development.
+- Use `SECURE_COOKIES=true` when Odysseus is served through HTTPS by a trusted reverse proxy or private access gateway.
+- Do not expose it directly to the public internet without HTTPS and a trusted reverse proxy or private access layer.
+- Keep `.env`, `data/`, `logs/`, databases, uploads, generated media, backups, auth/session files, API keys, and model/provider tokens out of Git and private shares. They are ignored by default.
+- Review `data/auth.json` after first boot: disable open signup unless you intentionally want it, make only your own account admin, and keep demo/test accounts non-admin.
+- Non-admin users do not get shell/Python/file read/write by default, and admin-only routes/tools such as MCP management, API tokens, webhooks, model/cookbook serving, backup/vault, and app settings are admin-gated. Other features are controlled by per-user privileges, so review each user's privileges before exposing a deployment.
+- Rotate any API keys or tokens that were ever pasted into a shared chat, demo, screenshot, or log.
+- If you enable API tokens or webhooks, create separate tokens per integration and delete unused ones.
+- Prefer binding manual development runs to `127.0.0.1`; bind to `0.0.0.0` only when you intentionally want LAN/reverse-proxy access.
+- Keep ChromaDB, SearXNG, ntfy, Ollama, vLLM, llama.cpp, databases, and raw model/provider APIs internal-only. Expose only the authenticated Odysseus web/API entrypoint through your trusted proxy or private access layer.
+- Before publishing a fork, run `git status --short` and confirm no private files from `.env`, `data/`, `logs/`, uploads, backups, or local databases are staged.
+
+### Private or proxied deployments
+Odysseus serves plain HTTP on its app port. Docker Compose binds Odysseus and the bundled services to `127.0.0.1` by default, so a typical production/private setup is:
+
+1. Keep Odysseus on localhost, for example `127.0.0.1:7000`.
+2. Terminate HTTPS at a trusted reverse proxy or private access gateway.
+3. Put the authenticated Odysseus web/API entrypoint behind that layer.
+4. Keep raw service and model ports internal-only.
+
+Cloudflare Access, Tailscale, Caddy, nginx, and Traefik can all fit this pattern; none are required by Odysseus. If your access layer reaches Odysseus on the same host, proxy to `http://127.0.0.1:7000` and keep `AUTH_ENABLED=true`, `LOCALHOST_BYPASS=false`, and `SECURE_COOKIES=true`.
+`ALLOWED_ORIGINS` lists exact permitted origins for cross-origin browser/API clients; ordinary same-origin reverse-proxy access usually does not need a special CORS entry.
+
+Common internal-only ports from the default docs/compose setup:
+
+| Port | Service |
+|---|---|
+| `7000` | Odysseus raw app port |
+| `8080` | SearXNG |
+| `8091` | ntfy |
+| `8100` | ChromaDB host port for manual/compose access |
+| `11434` | Ollama |
+| `8000-8020` | Common local model/provider APIs |
+
+## Configuration
+Most setup is done inside the app with `/setup` or **Settings**. Use `.env`
+for deployment-level defaults and secrets you want present before first boot.
+Key settings:
+
+| Variable | Default | Description |
+|---|---|---|
+| `LLM_HOST` | `localhost` | Your LLM server (e.g. `llm-host.local:8000`) |
+| `LLM_HOSTS` | -- | Comma-separated list for model discovery |
+| `OPENAI_API_KEY` | -- | Optional OpenAI key. Prefer adding providers in the app unless pre-seeding. |
+| `SEARXNG_INSTANCE` | `http://localhost:8080` | SearXNG URL. Docker overrides this to `http://searxng:8080`. |
+| `SEARXNG_SECRET` | generated on first Docker boot | Optional SearXNG cookie/CSRF secret. Leave blank unless you need to pin it. |
+| `APP_BIND` | `127.0.0.1` | Docker Compose host bind address for the web UI. Use `0.0.0.0` only for intentional LAN/reverse-proxy access. |
+| `APP_PORT` | `7000` | Docker Compose host port for the web UI. |
+| `APP_DATA_DIR` | `./data` | Docker Compose host directory for application data volumes. |
+| `APP_LOGS_DIR` | `./logs` | Docker Compose host directory for application logs. |
+| `AUTH_ENABLED` | `true` | Enable/disable login |
+| `LOCALHOST_BYPASS` | `false` | Development-only auth bypass for loopback requests. Keep false for shared/network deployments. |
+| `ALLOWED_ORIGINS` | `http://localhost,http://127.0.0.1` | Comma-separated exact permitted origins for cross-origin browser/API clients. |
+| `SECURE_COOKIES` | `false` | Set true when serving Odysseus through HTTPS at a trusted proxy or private access gateway. |
+| `DATABASE_URL` | `sqlite:///./data/app.db` | Database connection string |
+| `CHROMADB_HOST` | `localhost` | ChromaDB host for vector memory. Docker overrides this to `chromadb`. |
+| `CHROMADB_PORT` | `8100` | ChromaDB port for manual host runs. Docker overrides this to `8000`. |
+| `EMBEDDING_URL` | -- | OpenAI-compatible embeddings endpoint |
+| `ODYSSEUS_CHAT_UPLOAD_MAX_BYTES` | `10485760` | Chat/agent attachment cap in bytes. Raise for larger local PDFs or text documents. |
+| `ODYSSEUS_GALLERY_UPLOAD_MAX_BYTES` | `104857600` | Gallery image upload cap in bytes (100 MB). |
+| `ODYSSEUS_GALLERY_TRANSFORM_UPLOAD_MAX_BYTES` | `26214400` | Gallery transform input cap in bytes (25 MB). |
+| `ODYSSEUS_MEMORY_IMPORT_MAX_BYTES` | `10485760` | Memory import file cap in bytes (10 MB). |
+| `ODYSSEUS_PERSONAL_UPLOAD_MAX_BYTES` | `26214400` | Personal document upload cap in bytes (25 MB). |
+| `ODYSSEUS_EMAIL_COMPOSE_UPLOAD_MAX_BYTES` | `26214400` | Email compose attachment cap in bytes (25 MB). |
+| `ODYSSEUS_STT_MAX_AUDIO_BYTES` | `26214400` | Speech-to-text audio cap in bytes (25 MB). |
+| `ODYSSEUS_ICS_MAX_BYTES` | `10485760` | Calendar `.ics` import cap in bytes (10 MB). |
+
+All upload-limit vars are validated (must be a positive integer) and optional; an invalid value fails fast at startup.
+
+### Built-in MCP servers (optional setup)
+
+Odysseus auto-registers a few built-in MCP servers at startup. The npx-based ones (currently the browser server, `@playwright/mcp`) only start when their npm package is already in the local npx cache. If a package isn't cached, that server is skipped with a startup log message explaining what to do, so a fresh install does not block on a multi-minute npm download or hang if Playwright system deps are missing.
+
+To enable the browser MCP (page navigation, screenshots, vision), run once:
+
+```bash
+npx -y @playwright/mcp@latest --version
+```
+
+That installs `@playwright/mcp` plus Playwright (~300MB total). Restart Odysseus and the server will register at startup.

 ## Email draft + send
 
+- Prefer `POST /api/codex/emails/draft-document` for Codex-written email replies. It creates an editable Odysseus Document with `language: "email"` and does not touch IMAP/send.
 - `POST /api/codex/emails/draft` — body matches `SendEmailRequest` (`to`, `cc`, `bcc`, `subject`, `body`, `body_html`, `attachments`, `account_id`, `in_reply_to`, `references`). Requires `email:draft` (or `email:send`).
 - `POST /api/codex/emails/send` — same body. Requires `email:send`. Never send without explicit user instruction.

+Why: the `newest` sort in the cookbook ranks rows by release_date. Anything
+missing a date sorts to the bottom. This script pulls `created_at` from the
+HuggingFace API for each catalog entry without one (or all entries when
+--refresh is passed) and writes the catalog back.

+Usage:
+    python scripts/backfill_model_release_dates.py            # missing only
+    python scripts/backfill_model_release_dates.py --refresh  # all entries
+    python scripts/backfill_model_release_dates.py --limit 50 # cap requests
