----
-
-JSON formats for store path info and derivations have been updated with new versions and structured fields.
-
-## Store Path Info JSON (Version 2)
-
-The store path info JSON format has been updated from version 1 to version 2:
-
-- **Added `version` field**:
-
-  All store path info JSON now includes `"version": 2`.
-
-- **Structured `ca` field**:
-
-  Content address is now a structured JSON object instead of a string:
-
-  - Old: `"ca": "fixed:r:sha256:1abc..."`
-  - New: `"ca": {"method": "nar", "hash": {"algorithm": "sha256", "format": "base64", "hash": "EMIJ+giQ..."}}`
-  - Still `null` values for input-addressed store objects
-
-- **Structured hash fields**:
-
-  Hash values (`narHash` and `downloadHash`) are now structured JSON objects instead of strings:
-
-  - Old: `"narHash": "sha256:FePFYIlMuycIXPZbWi7LGEiMmZSX9FMbaQenWBzm1Sc="`
-  - New: `"narHash": {"algorithm": "sha256", "format": "base64", "hash": "FePFYIlM..."}`
-  - Same structure applies to `downloadHash` in NAR info contexts
-
-Nix currently only produces, and doesn't consume this format.
-
-**Affected command**: `nix path-info --json`
-
-## Derivation JSON (Version 4)
-
-The derivation JSON format has been updated from version 3 to version 4:
-
-- **Restructured inputs**:
-
-  Inputs are now nested under an `inputs` object:
-
-  - Old: `"inputSrcs": [...], "inputDrvs": {...}`
-  - New: `"inputs": {"srcs": [...], "drvs": {...}}`
-
-- **Consistent content addresses**:
-
-  Floating content-addressed outputs now use structured JSON format.
-  This is the same format as `ca` in in store path info (after the new version).
-
-Version 3 and earlier formats are *not* accepted when reading.
-
-**Affected command**: `nix derivation`, namely it's `show` and `add` sub-commands.

----
-
-S3 binary cache operations now happen via HTTP, leveraging `libcurl`'s native
-AWS SigV4 authentication instead of the AWS C++ SDK, providing significant
-improvements:
-
-- **Reduced memory usage**: Eliminates memory buffering issues that caused
-  segfaults with large files
-- **Fixed upload reliability**: Resolves AWS SDK chunking errors
-  (`InvalidChunkSizeError`)
-- **Lighter dependencies**: Uses lightweight `aws-crt-cpp` instead of full
-  `aws-cpp-sdk`, reducing build complexity
-
-The new implementation requires curl >= 7.75.0 and `aws-crt-cpp` for credential
-management.
-
-All existing S3 URL formats and parameters remain supported, however the store
-settings for configuring multipart uploads have changed:
-
-- **`multipart-upload`** (default: `false`): Enable multipart uploads for large
-  files. When enabled, files exceeding the multipart threshold will be uploaded

----
-
-S3 binary cache stores now support configuring the storage class for uploaded objects via the `storage-class` parameter. This allows users to optimize costs by selecting appropriate storage tiers based on access patterns.
-
-Example usage:
-
-```bash
-# Use Glacier storage for long-term archival
-nix copy --to 's3://my-bucket?storage-class=GLACIER' /nix/store/...
-
-# Use Intelligent Tiering for automatic cost optimization
-nix copy --to 's3://my-bucket?storage-class=INTELLIGENT_TIERING' /nix/store/...
-```
-
-The storage class applies to both regular uploads and multipart uploads. When not specified, objects use the bucket's default storage class.
-
-See the [S3 storage classes documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html) for available storage classes and their characteristics.

+is a JSON object with the following fields:
+
+* `name`:
+  The name of the derivation.
+  This is used when calculating the store paths of the derivation's outputs.
+
+* `version`:
+  Must be `3`.
+  This is a guard that allows us to continue evolving this format.
+  The choice of `3` is fairly arbitrary, but corresponds to this informal version:
+
+  - Version 0: A-Term format
+
+  - Version 1: Original JSON format, with ugly `"r:sha256"` inherited from A-Term format.
+
+  - Version 2: Separate `method` and `hashAlgo` fields in output specs
+
+  - Verison 3: Drop store dir from store paths, just include base name.
+
+  Note that while this format is experimental, the maintenance of versions is best-effort, and not promised to identify every change.
+
+* `outputs`:
+  Information about the output paths of the derivation.
+  This is a JSON object with one member per output, where the key is the output name and the value is a JSON object with these fields:
+
+  * `path`:
+    The output path, if it is known in advanced.
+    Otherwise, `null`.
+
+
+  * `method`:
+    For an output which will be [content addressed], a string representing the [method](@docroot@/store/store-object/content-address.md) of content addressing that is chosen.
+    Valid method strings are:
+
+    - [`flat`](@docroot@/store/store-object/content-address.md#method-flat)
+    - [`nar`](@docroot@/store/store-object/content-address.md#method-nix-archive)

+    - [`git`](@docroot@/store/store-object/content-address.md#method-git)
+
+    Otherwise, `null`.
+
+  * `hashAlgo`:
+    For an output which will be [content addressed], the name of the hash algorithm used.
+    Valid algorithm strings are:
+
+    - `blake3`
+    - `md5`
+    - `sha1`
+    - `sha256`
+    - `sha512`
+
+  * `hash`:
+    For fixed-output derivations, the expected content hash in base-16.

-  Information about a [store object](@docroot@/store/store-object.md).

-  ### Field Categories
-
-  Store object information can come in a few different variations.
-
-  Firstly, "impure" fields, which contain non-intrinsic information about the store object, may or may not be included.
-
-  Second, binary cache stores have extra non-intrinsic infomation about the store objects they contain.
-
-  Thirdly, [`nix path-info --json --closure-size`](@docroot@/command-ref/new-cli/nix3-path-info.html#opt-closure-size) can compute some extra information about not just the single store object in question, but the store object and its [closure](@docroot@/glossary.md#gloss-closure).
-
-  The impure and NAR fields are grouped into separate variants below.
-  See their descriptions for additional information.
-  The closure fields however as just included as optional fields, to avoid a combinatorial explosion of variants.

-title: Store Path
-description: |
-  A [store path](@docroot@/store/store-path.md) identifying a store object.
-
-  This schema describes the JSON representation of store paths as used in various Nix JSON APIs.
-
-  > **Warning**
-  >
-  > This JSON format is currently
-  > [**experimental**](@docroot@/development/experimental-features.md#xp-feature-nix-command)
-  > and subject to change.
-
-  ## Format
-
-  Store paths in JSON are represented as strings containing just the hash and name portion, without the store directory prefix.
-
-  For example: `"g1w7hy3qg1w7hy3qg1w7hy3qg1w7hy3q-foo.drv"`
-
-  (If the store dir is `/nix/store`, then this corresponds to the path `/nix/store/g1w7hy3qg1w7hy3qg1w7hy3qg1w7hy3q-foo.drv`.)
-
-  ## Structure
-
-  The format follows this pattern: `${digest}-${name}`
-
-  - **hash**: Digest rendered in a custom variant of [Base32](https://en.wikipedia.org/wiki/Base32) (20 arbitrary bytes become 32 ASCII characters)
-  - **name**: The package name and optional version/suffix information
-
-type: string
-pattern: "^[0123456789abcdfghijklmnpqrsvwxyz]{32}-.+$"
-minLength: 34

+- Fix dynamic attributes that are simple string expressions [#14642](https://github.com/NixOS/nix/issues/14642) [#14646](https://github.com/NixOS/nix/pull/14646)
+
+  Dynamic attributes are typically not allowed in [`let` expressions](https://nix.dev/manual/nix/2.32/language/syntax.html#let-expressions), but simple [string literals](https://nix.dev/manual/nix/2.32/language/string-literals.html) are allowed.

+- Fix use-after-free in derivation build scheduler [#14782](https://github.com/NixOS/nix/pull/14782)
+
+- Avoid querying remaining substituters after first success [#14836](https://github.com/NixOS/nix/issues/14836) [#14839](https://github.com/NixOS/nix/pull/14839)
+
+- Improve temporary path creation in hard link store optimisation [#7273](https://github.com/NixOS/nix/issues/7273) [#14680](https://github.com/NixOS/nix/pull/14680)
+
+  `auto-optimise-store` has been known to be flaky on Darwin due the usage of `rand()` when constructing the path of a temporary hardlink.
+
+- Move singletons out of headers [#14558](https://github.com/NixOS/nix/issues/14558)
+
+  Such variables have ["vague linkage"](https://gcc.gnu.org/onlinedocs/gcc-14.2.0/gcc/Vague-Linkage.html) and require special support from the dynamic linker to deduplicate across different shared libraries. Platforms such as Cygwin do not support this and duplicate the symbols instead.
+
+- Fix `curl` with `c-ares` failing to resolve DNS inside sandbox on macOS [#14859](https://github.com/NixOS/nix/pull/14859)
+
+- Fix `recursive-nix` [#14730](https://github.com/NixOS/nix/pull/14730)
+
+## Improvements
+
+- Support building manual with mdbook 0.5 [#14628](https://github.com/NixOS/nix/issues/14628) [#14693](https://github.com/NixOS/nix/pull/14693)

-The *build trace* is a [memoization table](https://en.wikipedia.org/wiki/Memoization) for builds.
-It maps the inputs of builds to the outputs of builds.
-Concretely, that means it maps [derivations][derivation] to maps of [output] names to [store objects][store object].
-
-In general the derivations used as a key should be [*resolved*](./resolution.md).
-A build trace with all-resolved-derivation keys is also called a *base build trace* for extra clarity.
-If all the resolved inputs of a derivation are content-addressed, that means the inputs will be fully determined, leaving no ambiguity for what build was performed.
-(Input-addressed inputs however are still ambiguous. They too should be locked down, but this is left as future work.)
-
-Accordingly, to look up an unresolved derivation, one must first resolve it to get a resolved derivation.
-Resolving itself involves looking up entries in the build trace, so this is a mutually recursive process that will end up inspecting possibly many entries.
-
-Except for the issue with input-addressed paths called out above, base build traces are trivially *coherent* -- incoherence is not possible.
-That means that the claims that each key-value base build try entry makes are independent, and no mapping invalidates another mapping.
-
-Whether the mappings are *true*, i.e. the faithful recording of actual builds performed, is another matter.
-Coherence is about the multiple claims of the build trace being mutually consistent, not about whether the claims are individually true or false.
-
-In general, there is no way to audit a build trace entry except for by performing the build again from scratch.
-And even in that case, a different result doesn't mean the original entry was a "lie", because the derivation being built may be non-deterministic.
-As such, the decision of whether to trust a counterparty's build trace is a fundamentally subject policy choice.
-Build trace entries are typically *signed* in order to enable arbitrary public-key-based trust polices.
-
-## Derived build traces {#derived}
-
-Implementations that wish to memoize the above may also keep additional *derived* build trace entries that do map unresolved derivations.
-But if they do so, they *must* also keep the underlying base entries with resolved derivation keys around.
-Firstly, this ensures that the derived entries are merely cache, which could be recomputed from scratch.
-Secondly, this ensures the coherence of the derived build trace.
-
-Unlike with base build traces, incoherence with derived build traces is possible.
-The key ingredient is that derivation resolution is only deterministic with respect to a fixed base build trace.
-Without fixing the base build trace, it inherits the subjectivity of base build traces themselves.
-
-Concretely, suppose there are three derivations \\(a\\), \\(b\\), and \\(c\\).
-Let \\(a\\) be a resolved derivation, but let \\(b\\) and \\(c\\) be unresolved and both take as an input an output of \\(a\\).
-Now suppose that derived entries are made for \\(b\\) and \\(c\\) based on two different entries of \\(a\\).
-(This could happen if \\(a\\) is non-deterministic, \\(a\\) and \\(b\\) are built in one store, \\(a\\) and \\(c\\) are built in another store, and then a third store substitutes from both of the first two stores.)
-
-If trusting the derived build trace entries for \\(b\\) and \\(c\\) requires that each's underlying entry for \\(a\\) be also trusted, the two different mappings for \\(a\\) will be caught.
-However, if \\(b\\) and \\(c\\)'s entries can be combined in isolation, there will be nothing to catch the contradiction in their hidden assumptions about \\(a\\)'s output.

+<!---
 
-A naive implementation of an output hash computation for input-addressed outputs would be to hash the derivation hash and output together.
-This clearly has the uniqueness properties we want for input-addressed outputs, but suffers from an inefficiency.
-Specifically, new builds would be required whenever a change is made to a fixed-output derivation, despite having provably no differences in the inputs to the new derivation compared to what it used to be.
-Concretely, this would cause a "mass rebuild" whenever any fetching detail changes, including mirror lists, certificate authority certificates, etc.

+This is done by the function `hashDrv`, shown in Figure 5.10.
+It distinguishes between two cases.
+If the derivation is a fixed-output derivation, then it computes a hash over just the `outputHash` attributes.
 
-First, a word on inputs.
-`hashQuotientDerivation` is only defined on derivations whose [inputs](@docroot@/store/derivation/index.md#inputs) take the first-order form:
-```typescript
-type ConstantPath = {

+If the derivation is not a fixed-output derivation, we replace each element in the derivation’s inputDrvs with the result of a call to `hashDrv` for that element.
+(The derivation at each store path in `inputDrvs` is converted from its on-disk ATerm representation back to a `StoreDrv` by the function `parseDrv`.)

+In the actual implementation, memoisation is used to reduce this to `O(V + E)` complexity for a graph with E edges.

-### `hashQuotientDerivation`
-
-We replace each element in the derivation's `inputDrvOutputs` using data from a call to `hashOutputsOrQuotientDerivation` on the `drvPath` of that element.
-When `hashOutputsOrQuotientDerivation` returns a single drv hash (because the input derivation in question is input-addressing), we simply swap out the `drvPath` for that hash, and keep the same output name.
-When `hashOutputsOrQuotientDerivation` returns a map of content addresses per-output, we look up the output in question, and pair it with the output name `out`.
-
-The resulting pseudo-derivation (with hashes instead of store paths in `inputDrvs`) is then printed (in the ["ATerm" format](@docroot@/protocols/derivation-aterm.md)) and hashed, and this becomes the hash of the "quotient derivation".
-
-When calculating output hashes, `hashQuotientDerivation` is called on an almost-complete input-addressing derivation, which is just missing its input-addressed outputs paths.
-The derivation hash is then used to calculate output paths for each output.
-<!-- TODO describe how this is done. -->
-Those output paths can then be substituted into the almost-complete input-addressed derivation to complete it.

-> This is not fatal because the deviation would only apply for content-addressing derivations with more than one output, and that only occurs in the floating case, which is [experimental][xp-feature-ca-derivations].
-> Once this bug is fixed, this note will be removed.
-
-### `hashOutputsOrQuotientDerivation`
-
-How does `hashOutputsOrQuotientDerivation` in turn work?
-It consists of two main cases, based on whether the outputs of the derivation are to be input-addressed or content-addressed.
-
-#### Input-addressed outputs case
-
-In the input-addressed case, it just calls `hashQuotientDerivation`, and returns that derivation hash.
-This makes `hashQuotientDerivation` and `hashOutputsOrQuotientDerivation` mutually-recursive.
-
-> **Note**
->
-> In this case, `hashQuotientDerivation` is being called on a *complete* input-addressing derivation that already has its output paths calculated.
-> The `inputDrvs` substitution takes place anyways.
-
-#### Content-addressed outputs case
-
-If the outputs are [content-addressed](./content-address.md), then it computes a hash for each output derived from the content-address of that output.
-
-> **Note**
->
-> In the [fixed](./content-address.md#fixed) content-addressing case, the outputs' content addresses are statically specified in advance, so this always just works.
-> (The fixed case is what the pseudo-code shows.)
->
-> In the [floating](./content-address.md#floating) case, the content addresses are not specified in advance.
-> This is what the "or get from [build trace](@docroot@/store/build-trace.md) if floating" comment refers to.
-> In this case, the algorithm is *stuck* until the input in question is built, and we know what the actual contents of the output in question is.
->
-> That is OK however, because there is no problem with delaying the assigning of input addresses (which, remember, is what `hashQuotientDerivation` is ultimately for) until all inputs are known.
-
-### Performance
-
-The recursion in the algorithm is potentially inefficient:
-it could call itself once for each path by which a subderivation can be reached, i.e., `O(V^k)` times for a derivation graph with `V` derivations and with out-degree of at most `k`.
-In the actual implementation, [memoisation](https://en.wikipedia.org/wiki/Memoization) is used to reduce this cost to be proportional to the total number of `inputDrvOutputs` encountered.
-
-### Semantic properties
-
-*See [this chapter's appendix](@docroot@/store/math-notation.md) on grammar and metavariable conventions.*
-
-In essence, `hashQuotientDerivation` partitions input-addressing derivations into equivalence classes: every derivation in that equivalence class is mapped to the same derivation hash.
-We can characterize this equivalence relation directly, by working bottom up.
-
-We start by defining an equivalence relation on first-order output deriving paths that refer content-addressed derivation outputs. Two such paths are equivalent if they refer to the same store object:
-
-\\[
-\\begin{prooftree}
-\\AxiomC{$d\_1$ is content-addressing}
-\\AxiomC{$d\_2$ is content-addressing}
-\\AxiomC{$
-  {}^\*(\text{path}(d\_1), o\_1)
-  \=
-  {}^\*(\text{path}(d\_2), o\_2)
-$}
-\\TrinaryInfC{$(\text{path}(d\_1), o\_1) \\,\\sim_{\\mathrm{CA}}\\, (d\_2, o\_2)$}
-\\end{prooftree}
-\\]
-
-where \\({}^*(s, o)\\) denotes the store object that the output deriving path refers to.
-
-We will also need the following construction to lift any equivalence relation on \\(X\\) to an equivalence relation on (finite) sets of \\(X\\) (in short, \\(\\mathcal{P}(X)\\)):
-
-\\[
-\\begin{prooftree}
-\\AxiomC{$\\forall a \\in A. \\exists b \\in B. a \\,\\sim\_X\\, b$}
-\\AxiomC{$\\forall b \\in B. \\exists a \\in A. b \\,\\sim\_X\\, a$}
-\\BinaryInfC{$A \\,\\sim_{\\mathcal{P}(X)}\\, B$}
-\\end{prooftree}
-\\]
-
-Now we can define the equivalence relation \\(\\sim_\\mathrm{IA}\\) on input-addressed derivation outputs. Two input-addressed outputs are equivalent if their derivations are equivalent (via the yet-to-be-defined \\(\\sim_{\\mathrm{IADrv}}\\) relation) and their output names are the same:
-
-\\[
-\\begin{prooftree}
-\\AxiomC{$d\_1$ is input-addressing}
-\\AxiomC{$d\_2$ is input-addressing}
-\\AxiomC{$d\_1 \\,\\sim_{\\mathrm{IADrv}}\\, d\_2$}
-\\AxiomC{$o\_1 = o\_2$}
-\\QuaternaryInfC{$(\text{path}(d\_1), o\_1) \\,\\sim_{\\mathrm{IA}}\\, (\text{path}(d\_2), o\_2)$}
-\\end{prooftree}
-\\]
-
-And now we can define \\(\\sim_{\\mathrm{IADrv}}\\).
-Two input-addressed derivations are equivalent if their content-addressed inputs are equivalent, their input-addressed inputs are also equivalent, and they are otherwise equal:
-
-<!-- cheating a bit with the semantics to get a good layout that fits on the page -->
-
-\\[
-\\begin{prooftree}
-\\alwaysNoLine
-\\AxiomC{$
-  \\mathrm{caInputs}(d\_1)

-  \\mathrm{caInputs}(d\_2)
-$}
-\\AxiomC{$
-  \\mathrm{iaInputs}(d\_1)
-  \\,\\sim_{\\mathcal{P}(\\mathrm{IA})}\\,
-  \\mathrm{iaInputs}(d\_2)
-$}
-\\BinaryInfC{$
-  d\_1\left[\\mathrm{inputDrvOutputs} := \\{\\}\right]
-  \=
-  d\_2\left[\\mathrm{inputDrvOutputs} := \\{\\}\right]
-$}
-\\alwaysSingleLine
-\\UnaryInfC{$d\_1 \\,\\sim_{\\mathrm{IADrv}}\\, d\_2$}
-\\end{prooftree}
-\\]
-
-where \\(\\mathrm{caInputs}(d)\\) returns the content-addressed inputs of \\(d\\) and \\(\\mathrm{iaInputs}(d)\\) returns the input-addressed inputs.
-
-> **Note**
->
-> An astute reader might notice that that nowhere does `inputSrcs` enter into these definitions.
-> That means that replacing an input derivation with its outputs directly added to `inputSrcs` always results in a derivation in a different equivalence class, despite the resulting input closure (as would be mounted in the store at build time) being the same.

-# Derivation Resolution
-
-*See [this chapter's appendix](@docroot@/store/math-notation.md) on grammar and metavariable conventions.*
-
-To *resolve* a derivation is to replace its [inputs] with the simplest inputs — plain store paths — that denote the same store objects.
-
-Derivations that only have store paths as inputs are likewise called *resolved derivations*.
-(They are called that whether they are in fact the output of derivation resolution, or just made that way without non-store-path inputs to begin with.)
-
-## Input Content Equivalence of Derivations
-
-[Deriving paths][deriving-path] intentionally make it possible to refer to the same [store object] in multiple ways.
-This is a consequence of content-addressing, since different derivations can produce the same outputs, and the same data can also be manually added to the store.
-This is also a consequence even of input-addressing, as an output can be referred to by derivation and output name, or directly by its [computed](./derivation/outputs/input-address.md) store path.
-Since dereferencing deriving paths is thus not injective, it induces an equivalence relation on deriving paths.
-
-Let's call this equivalence relation \\(\\sim\\), where \\(p_1 \\sim p_2\\) means that deriving paths \\(p_1\\) and \\(p_2\\) refer to the same store object.
-
-**Content Equivalence**: Two deriving paths are equivalent if they refer to the same store object:
-
-\\[
-\\begin{prooftree}
-\\AxiomC{${}^*p_1 = {}^*p_2$}
-\\UnaryInfC{$p_1 \\,\\sim_\\mathrm{DP}\\, p_2$}
-\\end{prooftree}
-\\]
-
-where \\({}^\*p\\) denotes the store object that deriving path \\(p\\) refers to.
-
-This also induces an equivalence relation on sets of deriving paths:
-
-\\[
-\\begin{prooftree}
-\\AxiomC{$\\{ {}^*p | p \\in P_1 \\} = \\{ {}^*p | p \\in P_2 \\}$}
-\\UnaryInfC{$P_1 \\,\\sim_{\\mathcal{P}(\\mathrm{DP})}\\, P_2$}
-\\end{prooftree}
-\\]
-
-**Input Content Equivalence**: This, in turn, induces an equivalence relation on derivations: two derivations are equivalent if their inputs are equivalent, and they are otherwise equal:
-
-\\[
-\\begin{prooftree}
-\\AxiomC{$\\mathrm{inputs}(d_1) \\,\\sim_{\\mathcal{P}(\\mathrm{DP})}\\, \\mathrm{inputs}(d_2)$}
-\\AxiomC{$
-  d\_1\left[\\mathrm{inputs} := \\{\\}\right]
-  \=
-  d\_2\left[\\mathrm{inputs} := \\{\\}\right]
-$}
-\\BinaryInfC{$d_1 \\,\\sim_\\mathrm{Drv}\\, d_2$}
-\\end{prooftree}
-\\]
-
-Derivation resolution always maps derivations to input-content-equivalent derivations.
-
-## Resolution relation
-
-Dereferencing a derived path — \\({}^\*p\\) above — was just introduced as a black box.
-But actually it is a multi-step process of looking up build results in the [build trace] that itself depends on resolving the lookup keys.
-Resolution is thus a recursive multi-step process that is worth diagramming formally.
-
-We can do this with a small-step binary transition relation; let's call it \\(\rightsquigarrow\\).
-We can then conclude dereferenced equality like this:
-
-\\[
-\\begin{prooftree}
-\\AxiomC{$p\_1 \\rightsquigarrow^* p$}
-\\AxiomC{$p\_2 \\rightsquigarrow^* p$}
-\\BinaryInfC{${}^*p\_1 = {}^*p\_2$}
-\\end{prooftree}
-\\]
-
-I.e. by showing that both original items resolve (over 0 or more small steps, hence the \\({}^*\\)) to the same exact item.
-
-With this motivation, let's now formalize a [small-step](https://en.wikipedia.org/wiki/Operational_semantics#Small-step_semantics) system of reduction rules for resolution.
-

-### \\(\rightsquigarrow\\) binary relation
-
-> **Remark**
->
-> Actually, to be completely formal we would need to keep track of the build trace we are choosing to resolve against.
->
-> We could do that by making \\(\rightsquigarrow\\) a ternary relation, which would pass the build trace to itself until it finally uses it in that one rule.
-> This would add clutter more than insight, so we didn't bother to write it.
->
-> There are other options too, like saying the whole reduction rule system is parameterized on the build trace, essentially [currying](https://en.wikipedia.org/wiki/Currying) the ternary \\(\rightsquigarrow\\) into a function from build traces to the binary relation written above.

-### Properties
-
-Like all well-behaved evaluation relations, partial resolution is [*confluent*](https://en.wikipedia.org/wiki/Confluence_(abstract_rewriting)).
-Also, if we take the symmetric closure of \\(\\rightsquigarrow^\*\\), we end up with the equivalence relations of the previous section.
-Resolution respects content equivalence for deriving paths, and input content equivalence for derivations.
-
-> **Remark**
->
-> We chose to define from scratch an "resolved" unary relation explicitly above.
-> But it can also be defined as the normal forms of the \\(\\rightsquigarrow^\*\\) relation:
->
-> \\[ a \text{ resolved} \Leftrightarrow \forall b. b \rightsquigarrow^* a \Rightarrow b = a\\]
->
-> In prose, resolved terms are terms which \\(\\rightsquigarrow^\*\\) only relates on the left side to the same term on the right side; they are the terms which can be resolved no further.
-
-## Partial versus Complete Resolution
-
-Similar to evaluation, we can also speak of *partial* versus *complete* derivation resolution.
-Partial derivation resolution is what we've actually formalized above with \\(\\rightsquigarrow^\*\\).
-Complete resolution is resolution ending in a resolved term (deriving path or derivation).
-(Which is a normal form of the relation, per the remark above.)
-
-With partial resolution, a derivation is related to equivalent derivations with the same or simpler inputs, but not all those inputs will be plain store paths.
-This is useful when the input refers to a floating content addressed output we have not yet built — we don't know what (content-address) store path will used for that derivation, so we are "stuck" trying to resolve the deriving path in question.
-(In the above formalization, this happens when the build trace is missing the keys we wish to look up in it.)
-
-Complete resolution is a *functional* relation, i.e. values on the left are uniquely related with values on the right.
-It is not however, a *total* relation (in general, assuming arbitrary build traces).
-This is discussed in the next section.
-
-## Termination
-
-For static derivations graphs, complete resolution is indeed total, because it always terminates for all inputs.
-(A relation that is both total and functional is a function.)
-
-For [dynamic][xp-feature-dynamic-derivations] derivation graphs, however, this is not the case — resolution is not guaranteed to terminate.
-The issue isn't rewriting deriving paths themselves:
-a single rewrite to normalize an output deriving path to a constant one always exists, and always proceeds in one step.
-The issue is that dynamic derivations (i.e. those that are filled-in the graph by a previous resolution) may have more transitive dependencies than the original derivation.
-
-> **Example**
->
-> Suppose we have this deriving path
-> ```json
-> {
->   "drvPath": {
->     "drvPath": "...-foo.drv",
->     "output": "bar.drv"
->   },
->   "output": "baz"
-> }
-> ```
-> and derivation `foo` is already resolved.
-> When we resolve deriving path we'll end up with something like.
-> ```json
-> {
->   "drvPath": "...-foo-bar.drv",
->   "output": "baz"
-> }
-> ```
-> So far is just an atomic single rewrite, with no termination issues.
-> But the derivation `foo-bar` may have its *own* dynamic derivation inputs.
-> Resolution must resolve that derivation first before the above deriving path can finally be normalized to a plain `...-foo-bar-baz` store path.
-
-The important thing to notice is that while "build trace" *keys* must be resolved.
-The *value* those keys are mapped to have no such constraints.
-An arbitrary store object has no notion of being resolved or not.
-But, an arbitrary store object can be read back as a derivation (as will in fact be done in case for dynamic derivations / nested output deriving paths).
-And those derivations need *not* be resolved.
-
-It is those dynamic non-resolved derivations which are the source of non-termination.
-By the same token, they are also the reason why dynamic derivations offer greater expressive power.

-# Secrets
-
-The store is readable to all users on the system. For this reason, it
-is generally discouraged to allow secrets to make it into the store.

-Even on a single-user system, separate system users isolate services

-weakens that isolation. When using external store caches the secrets

-Organize your derivations so that secrets are read from the filesystem
-(with appropriate access controls) at run time. Place the secrets on
