CI deploys the candidate environment -before PIACE runs. PIACE never embeds a Puppet runtime, runs agents, or issues -a write to PuppetDB. With `catalog_api: v4` the candidate compilation writes -nothing to PuppetDB either, because every v4 request disables fact and catalog -persistence; with `catalog_api: v3` the compiler stores the candidate facts and -catalog regardless, which is the constraint that shapes the v3 rules below. - -This design fixes the contracts deliberately left open in the requirements: -configuration merge rules, snapshot integrity, compiler compatibility, -normalization, safe rendering, bounded impact estimates, and outcome -precedence. The implementation must use the terminology in `CONTEXT.md`. - -### 1.1 Design goals - -- Deterministic per-target node diffs, aggregate diffs, and text/JSON/HTML - reports from the same internal result model. -- Strict source and target validation before a catalog is diffed. -- Independent least-privilege mTLS configuration for the compiler and - PuppetDB; no secret material in output. -- An explicit degraded-compatibility path for compiler catalog API v3, bounded - by what v3 cannot do: suppress persistence. -- Reusable, verifiable snapshots for environment-stable baselines. - -### 1.2 Explicit non-goals - -PIACE does not locally compile Puppet code; infer catalog changes for uncompiled -nodes; use PQL to expand target selection; retain history in PuppetDB; download -runtime dependencies; or render managed file content bytes. - -## 2.

Omitting an -artifact option writes text to stdout and suppresses that optional artifact; -CI can request all three explicitly. `--candidate-environment` overrides -`candidate.environment` for every target: the environment CI deployed is a -per-pipeline value, and a pipeline must be able to name it without rewriting -its own committed target file. `capture catalog --environment` is a separate -flag naming the environment to snapshot, and never a candidate override. The capture commands select targets from -the same target file and write the configured local snapshot paths. They never -write to PuppetDB. - -### 2.2 Service configuration - -A separate `--services` YAML file keeps endpoint and mTLS settings out of the -reviewable target selection file. It has `version: 1`, a `compiler` section, -and a `puppetdb` section. Each section requires an HTTPS endpoint, CA bundle, -client certificate, and private-key file. The two sections are independently -loaded, so paths may deliberately be identical. Private-key values are file -paths only; inline keys, bearer tokens, and insecure TLS are rejected. - - -Runtime configuration is read once, validated without emitting its contents, -and retained only as a redacted provenance projection. The process accepts only -`https` endpoints, requires a non-empty `ServerName` derived from the endpoint -host, disables credential forwarding across redirects, and applies timeouts and -body limits at the transport boundary. - -## 3. Target configuration resolution - -### 3.1 Resolved target model - -The target file remains the versioned selection and policy contract illustrated -in the requirements. A target resolves to this complete model before network -I/O: - -```text -certname -candidate: environment, catalog_api, allow_v3_fallback -facts: source, file? -baseline: source, environment, file? -exclude: []ExclusionRule -redact: []RedactionSelector -impact_estimate: enabled, timeout, result_limit -fail_on_diff -``` - -`catalog_api` is `v3` or `v4`; `allow_v3_fallback` defaults to `false` and is -valid only with `v4`. This explicit opt-in prevents a server capability error -from silently degrading both trusted-fact semantics and PuppetDB integrity. A -v4 request may fall back only for a documented unsupported-endpoint or -unsupported-version response. It must not fall back after authentication, -authorization, timeout, malformed response, or candidate identity/environment -mismatch. Any fallback is recorded as a warning and is subject to every v3 rule -below, including the persistence consequences — an operator who enables the -fallback is accepting that a compiler without v4 will have the target's stored -factset and catalog overwritten. - -Any target that can compile over v3 requires `baseline.source: file` -(requirements.md 1.8) — `catalog_api: v3`, and equally `catalog_api: v4` with -`allow_v3_fallback: true`. A v3 compilation overwrites the target's stored -PuppetDB catalog and factset with the candidate's, so a `puppetdb` baseline is -not merely inaccurate here: the candidate request destroys the baseline the run -reads, and the failure surfaces on the *next* target or the *next* run as a -baseline-environment mismatch. Both combinations are configuration errors -rejected during resolution rather than runtime warnings, because a fallback -that has already fired cannot be un-fired. Pairing a file baseline with v3 -still leaves the compilation itself mutating: see section 5. - -### 3.2 Merge and validation rules - -1. Resolve global defaults first, then replace each scalar or object field with - a target override. A target must have a non-empty, unique certname. -2. Global exclusion and redaction lists are prepended to their per-target lists; - they are never replaced. Duplicates are retained once in their first-seen - order for provenance and evaluation. -3. `exclude.type` is an exact, case-sensitive Puppet resource type. Its `title` - uses the Go `path.Match` glob dialect, case-sensitively. Invalid glob syntax - is a validation error. `*` matches any title characters. -4. A redaction selector is `{type, parameter}`: both fields are exact, - case-sensitive names. Redaction applies to every matching parameter, - including values that did not change but appear in provenance or diagnostics. -5. A relative local file path is resolved against the target-file directory. - `{certname}` may occur only as an entire path component. Certnames with `/`, - `\\`, NUL, or `..` are invalid. Template expansion must remain beneath the - target-file directory; an explicit absolute file path is allowed. -6. `facts.source: file` requires `facts.file`; `baseline.source: file` requires - `baseline.file`. PuppetDB sources reject a file value. Every target needs a - candidate environment, fact source, baseline source, baseline environment, - API version, and `fail_on_diff` after resolution. An invocation override - (section 2.1's `--candidate-environment`) is substituted into the decoded - target file before resolution, so it satisfies that requirement and is - validated and recorded as a file-supplied value would be. -7. Impact limits must be positive; the effective network request deadline is - the smaller of the service deadline and the target impact timeout. - -Invalid configuration is one operational diagnostic and prevents every service -call. Resolved configuration provenance includes source choices, paths, API, -policy values, and matching rules, but never endpoint credentials or private -key paths. - -## Architecture - -```text -CLI/config -> resolver -> target work queue -------------------------------+ - | | - +-------------+-------------+ | - v v v - fact-source adapter baseline-source adapter compiler adapter - (PuppetDB or envelope) (PuppetDB or envelope) (v3/v4 over mTLS) - \ | / - +--------------------------+--------------------------+ - v - catalog normalizer / content verifier - v - semantic differ -> exclusion evaluator - v - aggregate builder -> impact estimator - v - redaction boundary -> shared result -> text/JSON/HTML -``` - -Targets are independent and may run with bounded concurrency. The default is -one target at a time; a future explicit `--parallel` option may raise it, but -must preserve target-order result emission. A target error is captured in that -target's node result and processing continues for the other valid targets. -Global configuration failure is the sole fail-fast condition. - -## Components and Interfaces - -Interfaces separate remote wire formats from domain behavior: - -- `FactSource.Load(target) -> Factset, Provenance` -- `CatalogSource.LoadBaseline(target) -> Catalog, Provenance` -- `Compiler.RequestCandidate(target, facts) -> Catalog, Provenance, Warnings` -- `ContentResolver.Digest(reference, context) -> DigestEvidence` -- `ImpactQuerier.Estimate(resourceIdentity, limits) -> ImpactEstimate` - -Adapters preserve raw response bytes only transiently. They convert only -recognized, schema-validated responses into domain data. Unknown or malformed -catalog/fact data is an operational normalization failure, never an empty -catalog or factset. - -## 5. Compiler request and compatibility policy - -The compiler adapter owns protocol-specific paths, request encoding, response -shape validation, content retrieval authorization, and error classification. -Its contract requires that the returned catalog identify the requested certname -and candidate environment exactly. A non-2xx compiler response, semantic -request rejection, identity mismatch, or environment mismatch is a -**compilation failure**. - -For API v4, PIACE uses the compiler's target trusted-fact mechanism. When the -selected factset exposes a valid trusted-fact structure, the adapter sends it -as `trusted_facts` with the selected target facts. When it does not, PIACE -uses the documented v4 omitted-field behavior only when the compiler is -configured to obtain target trusted facts from PuppetDB; the result records -`trusted_facts_source: compiler_lookup`. If neither source is available, -PIACE fails compilation rather than inventing trusted facts. The response -provenance records `provided` or `compiler_lookup` but never trusted-fact -values. - -Every v4 request carries `persistence: {facts: false, catalog: false}`. This is -not configurable. It is what allows requirement 1.6 to hold and what keeps a -PuppetDB baseline meaningful: the compiler returns the candidate catalog and -writes nothing, so the target's stored factset and catalog remain those of its -last real agent run. - -For API v3, and every permitted v4-to-v3 fallback, PIACE attaches a prominent, -non-suppressible warning to the target, covering both v3 consequences: the -catalog-reader certificate can make `$trusted` reflect the service identity -rather than the target, and the compilation writes the candidate facts and -candidate catalog into PuppetDB under the candidate environment. The same -warning appears in the shared result, text, JSON, and HTML. - -The v3 endpoint offers no persistence control, so neither consequence is -avoidable from the client: the compiler saves the facts submitted with the -request, and stores the compiled catalog through its PuppetDB catalog cache -terminus. PIACE contains v3's blast radius through configuration -(`baseline.source: file` is mandatory, section 3.1) and reports it through the -warning; it cannot prevent it. - -Puppet Server and OpenVox are treated identically. Both serve v3 and v4, both -authorize a catalog-reader certificate through `auth.conf`, and both honour the -v4 `persistence` field, so `catalog_api` alone determines PIACE's guarantees. -There is no implementation-specific branch anywhere in the adapter. - -PIACE does not probe alternate API versions speculatively. Capture catalog uses -the exact same adapter and policy as comparison and records the requested API, -effective API, environment, factset identity, and trusted-fact source. - -## Data Models - -### Snapshot envelopes and capture - -Snapshot files are UTF-8 JSON PIACE envelopes, not bare Puppet payloads: - -```json -{ - "format_version": 1, - "kind": "factset", - "target": "web-01.example.test", - "source": {"kind": "puppetdb", "producer": "..."}, - "captured_at": "2026-08-24T00:00:00Z", - "requested_environment": "production", - "compiler_api": "v4", - "input_factset_identity": "sha256:...", - "payload_checksum": "sha256:...", - "payload": {} -} -``` - -`kind` is `factset` or `catalog`. Fields inapplicable to a factset are omitted; -`requested_environment`, `compiler_api`, and `input_factset_identity` are -mandatory for catalog snapshots. `source` records the adapter and producer -identity when supplied by the service. The payload retains the original -validated service document, not a lossy normalized form. - -`payload_checksum` is SHA-256 over the compact canonical JSON encoding of only -`payload`: map keys sort lexicographically by UTF-8 bytes, arrays retain order, -strings use JSON escaping, and parsed numeric tokens normalize to their exact -base-10 numeric value. The same in-tree canonical encoder is used for writing -and validation. Envelope metadata is excluded from the checksum to allow a -future migration tool to add non-semantic metadata without rewriting payload -integrity; `format_version` gates such migrations. - -Writes use a same-directory temporary file, mode `0600`, `fsync`, atomic rename, -and a directory sync where supported. Capture refuses to overwrite a snapshot -unless `--replace` is supplied. Reuse validates version, kind, target, -checksum, required metadata, and file decoding before it is accepted. A catalog -snapshot selected as a baseline must also match the resolved baseline -environment; a fact snapshot supplies its recorded identity to candidate -provenance. Any violation is an operational error for that target. - - -## 7. Semantic graph comparison - -### 7.1 Normalized catalog model - -A catalog normalizes into a resource map and an edge set. A resource key is the -exact Puppet identity `Type[title]`; type and title are strings with no case -folding. A graph edge key is the ordered pair `(source identity, target -identity)`; direction is significant. Resources and edges are sorted by those -keys before comparison and serialization. - -Each parameter becomes a typed canonical value. Strings, booleans, null/undef, -and numbers retain semantic type; number comparisons use exact normalized -decimal values rather than machine floating point; arrays retain order; object -keys sort recursively. Catalog data outside this JSON-compatible value domain -is rejected as a normalization error unless the protocol adapter has a defined, -lossless translation. Tags, source file/line, and metadata unrelated to managed -content are discarded before comparison. - -A node diff contains four distinct kinds: resource added, resource removed, -parameter changed, and edge added/removed. Parameter changed includes canonical -before/after values internally and a redaction-safe projection externally. -Equivalent aggregate keys include kind, identity, parameter name when relevant, -and the unredacted canonical comparison evidence. Raw values never enter logs, -PQL, serialized reports, templates, or persistent aggregate state. - -### 7.2 File-content evidence - -`File` is handled in addition to normal parameter comparison. PIACE determines -effective-content evidence in this priority order: - -1. hash inline `content` and compare the digest; -2. compare an authoritative compiled content checksum when both catalogs expose - a recognized compatible checksum; -3. retrieve the referenced content through the compiler adapter when a source - or reference must be resolved, then compare cryptographic digests; -4. if retrieval cannot establish comparable bytes, report `reference_changed` - or `content_indeterminate` rather than claiming a verified content change. - -Source/reference changes are always reported without rendering their bytes. A -retrieval failure carries a target diagnostic and makes any unresolved content -comparison non-clean; it cannot silently collapse into an unchanged file. The -result exposes only checksum algorithm, digest, evidence source, and comparison -state. Digest values are not a substitute for parameter redaction: a redacted -content selector emits a stable `REDACTED` value while preserving the change -classification and no digest in reports. - -### 7.3 Exclusions and redaction ordering - -Diffing first establishes complete graph semantics. Exclusion evaluation then -matches resource identities and removes matching resource differences. It also -suppresses any edge difference attached to an excluded identity. The result -retains deterministic counts by rule and by suppressed kind, not hidden raw -parameter values. Policy evaluation and aggregate building consume only the -remaining differences. - -Redaction applies after semantic equality and exclusions but before result -serialization, template data, diagnostic composition, and rendering. Puppet -`Sensitive` wrappers are detected recursively; their payload is never copied to -the serializable result. Configured selectors replace matched values with the -constant `""`. Errors quote identities and parameter names only, never -parameter value excerpts. This ordering preserves correct comparisons without -leaking values or merging distinct sensitive changes in aggregate groups. - -## 8. Impact estimation - -Impact estimation runs only for non-excluded resource additions, removals, and -parameter changes; it does not run for edge-only differences. For each unique -exact `Type[title]`, the PuppetDB adapter emits the PQL projection: - -```text -resources[certname] { type = and title = } -``` - -The adapter uses one PQL string-literal encoder, sends `limit = result_limit + -1`, requests certname ordering when the PuppetDB API supports it, and sorts the -returned certnames locally in all cases. It preserves the exact generated PQL -and request options in the result. Receiving more than `result_limit` sets -`truncated: true` and retains the first `result_limit` sorted certnames as the -deterministic sample. A per-query deadline is the resolved impact timeout; -queries are bounded and may be sequential in v1 to limit PuppetDB load. - -Every estimate is visibly labeled **potential impact estimate**. It says only -that the latest stored catalog contains the resource; it never states that a -node will change and never schedules more compiler calls. Timeout, transport, -PQL, or response errors become a separately reported failed estimate. Because -an enabled estimate is requested analysis, an estimate failure contributes an -operational outcome after all other targets finish; disabled estimates produce -no request and no failure. - -## 9. Result schema and renderers - -The shared document begins with `schema_version: 1` and includes: - -- invocation metadata (tool version, UTC timestamp, resolved safe provenance); -- a deterministic, target-sorted node result for every selected target; -- baseline, facts, and candidate provenance, warnings, and diagnostics; -- complete non-excluded node diffs and exclusion summaries; -- aggregate groups sorted by kind and canonical identity; -- impact estimates, including exact PQL, limits, sample, truncation, timeout, - and failure state; and -- final outcome, exit code, and ordered reason list. - -JSON uses the in-tree canonical encoder. Text renders final outcome first, then -per-target status, node changes, warnings/errors, aggregate summary, and impact -summary. HTML embeds the redacted canonical result as escaped data and uses -inlined CSS/JavaScript only; it makes target failure, v3 warning, exclusions, -and final outcome visible without network access. HTML, text, and JSON derive -from the same redacted projection, preventing format drift or secret exposure. - -### 9.1 Display policy - -The three formats show the same document at three levels of detail, decided -through shared helpers so they cannot drift apart in what a value says. JSON -encodes the complete document and takes no options. HTML is complete too and -uses disclosure rather than omission: resource changes, edge changes, aggregate -groups, and each estimate's PQL, request options and full certname list are on -the page inside closed `
`. Every list of rows is closed and every -summary carries its count, so the page a reader lands on is an index of the run -— outcome, reasons, tally, and one line per target with a counted chip per -section — and one click reaches any of it. What stays outside every disclosure -is anything requirement 8.5 requires visibly marked (retrieval and compilation -failures, the v3 warning) and requirement 9.3's estimate label and note. Only -the text report omits, because a CI log is a linear read with nothing to -expand — it drops edge changes and each estimate's query mechanics, and caps an -estimate's certname sample unless `--impact-nodes` is passed. Requirements 5.3, -6.5, 7.4, 8.2, and 9.4 are discharged by JSON, and visibly by HTML as well. - -Two invariants keep this safe rather than lossy. Every section header counts -what it actually displays, not what the document holds. And a target whose only -differences are edges — `has_difference` true, no resource change — is never -rendered as unchanged: HTML shows the edges, and the text report prints an -explicit note, so no report reads as "nothing changed" on a run that exits -non-zero (requirements 10.2, 10.5). - -Requirement 8.3's "no HTTP server, a CDN, network access, or sibling assets" -also rules out webfonts and image files, so the HTML report uses system font -stacks with declared fallbacks and draws its disclosure markers in CSS. It -commits to one light palette rather than following the reader's system theme: -a review artifact is shared, printed, and pasted into tickets, and a single -appearance is a single thing to verify. - -## 10. Error taxonomy and outcomes - -PIACE records all target-local problems with an operation, safe reason, and -source context. Classes are: - -- **operational error**: configuration, TLS, baseline/fact retrieval, snapshot - validation, response decoding/normalization, content verification, or enabled - impact-estimate failure; -- **compilation failure**: a compiler request is rejected/fails, candidate - identity or environment does not match, or v4 trusted-fact requirements are - unmet; -- **policy-disallowed difference**: a target with `fail_on_diff: true` has a - non-excluded semantic difference; and -- **success**: all requested work completed, with either no differences - (`clean`) or differences allowed by every affected target policy - (`differences_allowed`). - -The reducer uses the following precedence across all targets: - -```text -operational error (exit 30) - > compilation failure (exit 20) - > policy-disallowed difference (exit 10) - > differences_allowed (exit 0) - > clean (exit 0) -``` - -A target's diagnostic remains in every output regardless of global precedence. -No result with an unreported retrieval, compilation, or normalization failure -can be clean. A reported v3 compatibility warning alone does not change exit -status; it makes trust semantics explicitly reviewable. - -## 11. Security and distribution - -The release uses standard-library Go where practical, builds with CGO disabled, -and ships static supported-platform binaries with a SHA-256 checksum manifest -and detached signature from the release process. The supported OS/architecture -matrix and signature verification key are release metadata, not implicit -runtime downloads. No Ruby, Puppet agent, Facter, package manager, or package -resolution is permitted at execution time. - -Endpoint allowlisting is configuration-derived: runtime requests go only to the -validated compiler and PuppetDB authorities and local snapshot paths. Logs use -structured safe fields and must be reviewed with the same redaction projection -as reports. TLS private keys and raw sensitive data have no `String`/marshal -paths. HTTP redirect following, arbitrary URL content retrieval, external HTML -assets, and user-controlled template execution are excluded. - -## 12. Key decisions and traceability - -| Decision | Rationale | Requirements | -| --- | --- | --- | -| Separate target and service files | Keeps reviewable scope/policy distinct from mTLS locations. | 3, 4 | -| Explicit v3 fallback opt-in | Prevents silent loss of v4 trusted-fact behavior and silent PuppetDB mutation. | 2, 7 | -| v4 persistence always disabled | The only client-side control that keeps a candidate compilation out of PuppetDB. | 1, 7 | -| v3 requires a file baseline | A v3 candidate compilation overwrites a PuppetDB baseline, including its own run's. | 1, 7 | -| SHA-256 canonical payload envelope | Detects snapshot corruption without a Puppet runtime. | 11 | -| Continue valid targets after local errors | Produces actionable CI evidence without hiding failures. | 8, 10 | -| Redact after equality, before results | Maintains correct diff semantics and prevents disclosure. | 3, 8 | -| Enabled impact failure is operational | A requested bounded analysis must not be silently omitted. | 9, 10 | - -The external protocol details are isolated behind the compiler and PuppetDB -adapters. The v3/v4 request shapes, the v3 `Accept` requirement, the v4 -response envelope, and the v3/v4 persistence behaviour were verified against a -deployed OpenVox compiler and PuppetDB on 2026-08-25 (requirements.md section -7). For any other compiler or PuppetDB version, fixture captures must verify -request fields, response shapes, checksum semantics, file-content endpoints, -and PQL options before that combination is declared supported; adapter support -is not enabled merely because another implementation accepts a similar -endpoint. - - -## Correctness Properties - -### Property 1: Deterministic results - -**Validates: Requirements 8.6** - -For the same validated service/snapshot inputs and resolved configuration, -PIACE emits byte-identical canonical JSON and equivalently ordered text and -HTML data. - -### Property 2: Verified snapshot acceptance - -**Validates: Requirements 11.6** - -Every accepted baseline and fact snapshot has a matching kind, target, format -version, and SHA-256 payload checksum; no invalid envelope reaches -normalization. - -### Property 3: Candidate identity integrity - -**Validates: Requirements 1.5** - -Every candidate catalog compared belongs to its requested target and candidate -environment; a response mismatch is never diffed. - -### Property 4: Complete exclusion suppression - -**Validates: Requirements 6.3** - -Excluded resources and every edge touching one are absent from policy and -aggregate inputs, while their safe suppression counts remain visible. - -### Property 5: Redaction containment - -**Validates: Requirements 8.7** - -Sensitive and selector-redacted values never occur in rendered output, -persisted result data, aggregate keys, or diagnostic excerpts. - -### Property 6: Clean-outcome completeness - -**Validates: Requirements 10.5** - -A final `clean` outcome implies every target was fully retrieved, compiled, -normalized, compared, and reported without unreported failure. - -## Error Handling - -Adapter errors preserve the operation (`load_facts`, `load_baseline`, -`request_candidate`, `verify_content`, or `estimate_impact`), target, source, -and safe status/context. They do not preserve raw body text by default, because -service errors can echo values. The outcome reducer in section 10 maps these -structured diagnostics after all valid targets have completed. Invalid global -configuration is reported once and prevents service traffic. - -## Testing Strategy - -Verification is fixture- and contract-driven. Unit-level coverage should lock -the canonical encoder, configuration resolution, envelope checks, graph -normalization, exclusions, redaction, aggregate equivalence, PQL quoting, and -outcome precedence. Adapter contract fixtures must represent every supported -PuppetDB, Puppet Server, and OpenVox response variant. Integration validation -uses an mTLS test service to prove authority isolation, no secret disclosure, -v3 warning behavior, v4 handling including the always-disabled persistence -fields, fallback limits, and deterministic self-contained report generation. Release validation proves the CGO-free -artifact and checksum/signature workflow. diff --git a/.kiro/specs/piace/requirements.md b/.kiro/specs/piace/requirements.md deleted file mode 100644 index ff52d60..0000000 --- a/.kiro/specs/piace/requirements.md +++ /dev/null @@ -1,532 +0,0 @@ -# PIACE: Requirements - -**Status:** Draft — requirements-stage input for Kiro spec-driven development. - -**Product name:** Puppet Impact Assessment & Change Explorer (PIACE) - -## 1. Product summary - -PIACE is a dependency-free Go command-line tool for CI/CD. It compares each -target node's selected baseline catalog—PuppetDB's latest catalog or a local -snapshot—with a catalog compiled by an existing compiler for the environment -deployed by CI. It reports individual node differences, cross-node aggregate -differences, and an optional PuppetDB-backed estimate of the wider -stored-catalog footprint of changed resources. - -PIACE is a client of PuppetDB and an existing Puppet Server or OpenVox -compiler. It does not compile Puppet code locally, embed a Puppet runtime, or -modify catalogs, facts, reports, code, or PuppetDB data. - -## 2. Goals - -- Make proposed Puppet environment changes reviewable in CI before deployment. -- Compile against the actual environment already deployed to the configured - compiler. -- Retrieve baseline catalogs and target facts from PuppetDB or reproducible - local per-target snapshot files. -- Support multiple targets supplied in a file. -- Produce readable terminal output and a portable, static HTML artifact. -- Remain installable in an air-gapped environment without runtime dependency - resolution. -- Support Puppet Server and OpenVox within a truthful compatibility contract. - -## 3. Non-goals - -- Running Puppet agents, applying a catalog, or changing node state. -- Reimplementing Puppet compilation, Facter, Hiera, PuppetDB, or a compiler. -- Claiming that PQL can prove which nodes would change without compiling them. -- AI analysis or integration; it is out of scope for this spec session. -- Replacing existing catalog-diff tools outside PIACE's CI use case. - -## 4. Domain language - -**Target** is a node identified by certname for which PIACE retrieves a -baseline catalog and requests a candidate catalog. - -**Baseline catalog** is the catalog selected from PuppetDB or a local catalog -snapshot for a target certname and is the state against which a candidate -catalog is compared. - -**Candidate catalog** is the catalog requested from the configured compiler for -a target certname in the CI environment under test. - -**Catalog-reader certificate** is a dedicated Puppet TLS identity authorized by -the compiler to request catalogs for all targets. - -**Fact source** is PuppetDB's latest factset or a local per-target factset -file. - -**Catalog source** is PuppetDB's latest catalog or a local per-target catalog -snapshot. - -**Snapshot** is a local capture of one target's factset or catalog, including -the source identity and environment required to reuse it as a PIACE input. - -**Exclusion rule** is a configured resource selector that suppresses matching -resource differences from the displayed and evaluated result. - -**Node diff** is the complete comparison result for one target. - -**Aggregate diff** groups equivalent changes from node diffs and identifies the -targets sharing each change. - -**Impact estimate** is an optional PQL result from PuppetDB's resources -endpoint that identifies nodes whose latest stored catalog contains a changed -exact resource type and title. It is an estimate, not proof of impact. - -## 5.

PIACE receives endpoint, -CA bundle, client certificate, and private-key locations through its -configuration; it must not obtain or mint credentials. PuppetDB retains only -the latest catalog and latest facts for a target. It is not a historical source -from which PIACE can recover an earlier production/default-environment state. - -## 6. Functional requirements - -### Requirement 1: CI catalog comparison - -**User Story:** As a Puppet maintainer, I want CI to compare the catalog a -target most recently received with the catalog it would receive from the -candidate environment, so that I can review changes before release. - -#### Acceptance Criteria - -1. WHEN PIACE is invoked with targets and a candidate environment, THE CLI - SHALL load a baseline catalog for every target from its configured catalog - source: PuppetDB or a local snapshot file. -2. WHEN a baseline catalog is loaded, THE CLI SHALL record its source, - certname, environment, producer timestamp, catalog identity/hash when - available, and source producer in the result. -3. WHEN `baseline.source` is PuppetDB and the returned catalog environment - differs from the target's configured baseline environment, THE CLI SHALL - fail the target before diffing it. -4. WHEN PIACE compiles a target, THE CLI SHALL request its candidate catalog - from the configured existing compiler rather than compile locally. -5. WHEN a compiler returns a candidate catalog, THE CLI SHALL verify that its - target identity and environment agree with the request, or report a - compilation error. -6. THE CLI SHALL not persist candidate facts or candidate catalogs to PuppetDB. -7. WHEN catalog API v4 is selected, THE CLI SHALL request compilation with - fact persistence and catalog persistence explicitly disabled, which is how - criterion 6 is satisfied. -8. WHEN a target can compile over v3 — `catalog_api: v3`, or `catalog_api: v4` - with `allow_v3_fallback: true` — THE CLI SHALL require `baseline.source: - file` for that target. A v3 compilation cannot satisfy criterion 6: the - compiler stores the submitted facts and the compiled catalog under the - candidate environment, which overwrites exactly the PuppetDB baseline the - comparison would read. A permitted fallback reaches that state at runtime, - when it is too late to reject the configuration, so the requirement is - keyed on what the target *may* do, not on what it did. See section 7.2. - -### Requirement 2: Target facts and trusted identity - -**User Story:** As a Puppet maintainer, I want candidate compilation to use -the correct target input, so that catalog differences do not result from an -unrelated client identity or stale data. - -#### Acceptance Criteria - -1. WHEN compiling a candidate catalog, THE CLI SHALL load the target's fact - data from its configured fact source: PuppetDB's latest factset or a local - per-target factset file. -2. THE CLI SHALL identify the fact source and factset identity used for each - candidate result. -3. THE CLI SHALL allow CI configuration to select the compiler catalog API v3 - or v4 for candidate compilation. v4 is the supported path; v3 is a degraded - path constrained by section 7.2. -4. WHEN v4 is selected, THE CLI SHALL send the target's own trusted facts in - the request, or use the compiler's PuppetDB trusted-fact lookup when the - target is explicitly configured for it, and SHALL fail compilation when - neither source is available rather than compiling with substituted trusted - facts. -5. WHEN v3 is selected or used as a fallback, THE CLI SHALL emit a prominent, - non-suppressible v3 compatibility warning in every output format. -6. THE v3 warning SHALL explain that `$trusted` can reflect the catalog-reader - certificate rather than the target identity. -7. THE v3 warning SHALL also explain that the compilation writes the candidate - facts and the candidate catalog into PuppetDB under the candidate - environment, overwriting the target's stored factset and catalog. - -### Requirement 3: Service authentication and authorization - -**User Story:** As a security owner, I want PIACE to use constrained mTLS -identities, so that CI does not need broadly shared interactive credentials. - -#### Acceptance Criteria - -1. THE CLI SHALL authenticate to the compiler using a dedicated - catalog-reader certificate authorized by the compiler's `auth.conf` to - request catalogs for target certnames other than its own. -2. THE CLI SHALL authenticate to PuppetDB using configured mTLS credentials. -3. THE CLI SHALL support independently configured compiler and PuppetDB TLS - identities, including the option for an installation to deliberately use - the same certificate for both services. -4. THE CLI SHALL load endpoint, CA certificate bundle, client certificate, and - private key from CI-provided configuration or files. -5. THE CLI SHALL NOT log private keys, certificate private material, request - authorization headers, or unredacted sensitive catalog parameter values. - -### Requirement 4: Target selection - -**User Story:** As a CI author, I want to supply a stable, reviewable list of -targets, so that the comparison scope is deterministic. - -#### Acceptance Criteria - -1. THE CLI SHALL accept a versioned YAML target file containing one or more - target certnames. -2. THE YAML schema SHALL support global defaults and per-target overrides for - candidate environment, candidate catalog API version, fact source, baseline - catalog source, baseline environment, local factset path, and local catalog - path. -3. WHEN a target omits a value, THE CLI SHALL apply the documented global - default or fail before contacting external services. -4. THE v1 target-file format SHALL NOT rely on a PQL expression that expands - the CI target set at runtime. - -### Requirement 5: Semantic catalog diff - -**User Story:** As a Puppet maintainer, I want PIACE to show configuration and -ordering changes rather than generated noise. - -#### Acceptance Criteria - -1. WHEN comparing catalogs, THE CLI SHALL identify added and removed - resources by Puppet resource identity. -2. WHEN a resource exists in both catalogs, THE CLI SHALL identify changed - parameters using a deterministic canonical value representation. -3. THE CLI SHALL identify added and removed dependency graph edges. -4. THE CLI SHALL produce the full node diff for each target independently. -5. THE CLI SHALL identify effective managed file-content changes, including - changed inline content, content source, and compiled content checksum where - available. -6. WHEN catalog data does not provide comparable content bytes or a checksum, - THE CLI SHALL retrieve the managed content as necessary and compare a - cryptographic digest. -7. THE CLI SHALL distinguish a verified file-content change from a changed - content reference when bytes or a checksum are not available to compare. -8. THE CLI SHALL NOT render managed file-content bytes in text, JSON, or HTML - output by default. -9. THE CLI SHALL exclude generated/noise-oriented fields from the semantic - diff: tags, source file/line information, and catalog metadata unrelated to - managed file content. - -### Requirement 6: Resource exclusions - -**User Story:** As a Puppet maintainer, I want to suppress known or irrelevant -resource changes, so that CI highlights actionable differences. - -#### Acceptance Criteria - -1. THE CLI SHALL support configurable exclusion rules for Puppet resources. -2. An exclusion rule SHALL use a `Type[title]` resource identity with an exact - Puppet resource type and a case-sensitive title pattern with wildcard - support. Its YAML representation SHALL use `type` and `title` keys. -3. WHEN a resource matches an exclusion rule, THE CLI SHALL suppress its - added, removed, and parameter differences. -4. WHEN an edge has an excluded resource as either endpoint, THE CLI SHALL - suppress that edge difference. -5. THE CLI SHALL include applied exclusion-rule identities and suppressed - difference counts in machine-readable and human-readable output. -6. THE YAML target file SHALL support global exclusion rules and per-target - exclusion-rule overrides. - -### Requirement 7: Aggregate diff - -**User Story:** As a reviewer, I want an aggregate view across the selected -targets, so that I can see common changes without manually correlating node -reports. - -#### Acceptance Criteria - -1. AFTER node diffs are produced, THE CLI SHALL group equivalent changes into - an aggregate diff. -2. FOR every aggregate change group, THE CLI SHALL report the number and - certnames of targets that exhibit it. -3. THE aggregate diff SHALL link or otherwise identify the underlying node - diffs. -4. THE aggregate diff SHALL retain resource additions, removals, parameter - changes, and edge changes as distinct change kinds. - -### Requirement 8: Text, HTML, and result data - -**User Story:** As a CI user, I want concise console output and a downloadable -review artifact, so that both automated jobs and humans can consume results. - -#### Acceptance Criteria - -1. THE CLI SHALL emit a text report suitable for CI logs. -2. THE CLI SHALL emit a versioned JSON report that contains the complete node - diffs, aggregate diff, configuration provenance, warnings, exclusions, - errors, and optional impact estimates. -3. THE CLI SHALL generate a static HTML report that can be opened using - `file://` without an HTTP server, a CDN, network access, or sibling assets. -4. THE HTML report SHALL include per-target node diffs and the aggregate diff. -5. THE HTML report SHALL visibly mark catalog retrieval failure, compilation - failure, the v3 trusted-fact compatibility warning, and excluded - differences. -6. THE result formats SHALL remain deterministic for identical input catalogs - and configuration. -7. THE CLI SHALL redact Puppet `Sensitive` values from text, JSON, and HTML - output. -8. THE CLI SHALL support configured parameter selectors that redact additional - values from text, JSON, and HTML output. - -### Requirement 9: Stored-catalog footprint estimate - -**User Story:** As a maintainer, I want PIACE to estimate the wider relevance -of changed resources, so that I can decide whether to expand validation. - -#### Acceptance Criteria - -1. THE CLI SHALL allow impact estimation to be enabled or disabled by - configuration. -2. WHEN impact estimation is enabled and a relevant resource change is present, - THE CLI SHALL query `/pdb/query/v4/resources` using PQL for nodes whose - latest stored catalog has the changed exact resource type and title. -3. THE CLI SHALL label the result **potential impact estimate**, and SHALL NOT - state that selected nodes will change. -4. THE CLI SHALL report the exact generated PQL query used for - an estimate. -5. THE CLI SHALL enforce configurable time and result limits on each impact - query. -6. WHEN an impact query reaches a configured result limit, THE CLI SHALL mark - the estimate as truncated and report a deterministic certname sample. -7. THE CLI SHALL report query scope, result count, truncation, timeout, and - query failures separately from catalog differences. -8. THE CLI SHALL not automatically compile impact-estimate nodes in v1. - -### Requirement 10: CI outcomes - -**User Story:** As a CI author, I want a machine-actionable result, so that -the pipeline can distinguish an acceptable diff from invalid analysis. - -#### Acceptance Criteria - -1. THE CLI SHALL return distinct outcomes for a clean comparison, a policy- - disallowed difference, catalog compilation failure, and operational error. -2. THE CLI SHALL report its outcome and its reason in text and HTML output. -3. THE YAML target file SHALL support a global `fail_on_diff` setting and a - per-target override. -4. WHEN `fail_on_diff` is enabled and a non-excluded semantic difference is - present, THE CLI SHALL return the policy-disallowed-difference outcome. -5. THE CLI SHALL never report a clean outcome when one or more targets have an - unreported retrieval, compilation, or normalization failure. - -### Requirement 11: Snapshot capture and reuse - -**User Story:** As a CI author, I want PIACE to capture stable target inputs -after a production/default-environment deployment, so that development-branch -comparisons do not accidentally baseline against a later catalog from another -environment. - -#### Acceptance Criteria - -1. THE CLI SHALL provide arguments or subcommands to retrieve each target's - latest factset from PuppetDB and write a local per-target factset file. -2. THE CLI SHALL provide arguments or subcommands to request each target's - catalog from the configured compiler for a specified environment and write - a local per-target catalog snapshot. -3. WHEN capturing a catalog snapshot, THE CLI SHALL use the target facts from - the configured fact source and SHALL record the target, requested - environment, compiler API version, fact source, and capture timestamp. -4. THE CLI SHALL store fact and catalog snapshots in PIACE envelopes rather - than bare Puppet JSON payloads. -5. A PIACE snapshot envelope SHALL contain its format version, target identity, - source, capture timestamp, integrity checksum, and—where applicable—the - requested environment, compiler API version, and input factset identity. -6. WHEN a local snapshot is selected as a fact or baseline catalog source, THE - CLI SHALL validate its recorded target identity and integrity checksum before - comparison. -7. THE CLI SHALL support a workflow in which CI refreshes catalog snapshots - from each target's default environment after merge to the main/production - branch, then uses those snapshots as development-branch baselines. - -### Requirement 12: Air-gapped distribution - -**User Story:** As an infrastructure operator, I want PIACE to work in an -air-gapped CI environment, so that the tool can be installed without external -package resolution. - -#### Acceptance Criteria - -1. PIACE SHALL be distributed as a CGO-free Go binary for supported target - platforms. -2. THE binary SHALL require no Ruby, Puppet agent, Facter, package manager, or - runtime dependency resolution. -3. THE release process SHALL provide a checksum and signature suitable for an - internal artifact repository. -4. THE CLI SHALL require network access only to the installation's configured - compiler and PuppetDB endpoints during execution. - -## 7. Compatibility and known constraints - -Puppet Server and OpenVox present PIACE with the same catalog contract. Both -serve `POST /puppet/v3/catalog/:certname` and `POST /puppet/v4/catalog`, both -authorize a dedicated catalog-reader certificate through `auth.conf`, and both -honour the v4 request's `persistence` field. PIACE therefore makes no -implementation-specific distinction: the API version selected in the target -file, not the compiler product, determines what PIACE can guarantee. - -### 7.1 v4 is the supported path - -A v4 request carries `persistence: {facts: false, catalog: false}` and the -target's own trusted facts. The compiler returns the catalog and writes nothing -to PuppetDB, which is what makes requirement 1.6 satisfiable and what makes a -PuppetDB baseline usable: the node's stored catalog and factset are exactly -what its last real agent run produced, both before and after PIACE runs. - -### 7.2 v3 is a degraded path that mutates PuppetDB - -The v3 catalog endpoint has no persistence control, and this is a property of -the endpoint, not of a particular compiler or configuration: - -- the compiler saves the facts submitted in the request, rewriting the target's - stored factset and its `facts_environment` to the candidate environment; -- the compiled catalog is stored through the master's PuppetDB catalog cache - terminus, rewriting the target's stored catalog, `catalog_environment`, and - `transaction_uuid` to the candidate compilation's. - -Two consequences follow, and both are contractual: - -1. **A PuppetDB baseline is impossible with v3.** PIACE reads the baseline, - then compiles the candidate — and the candidate compilation overwrites the - baseline that the next target, or the next run, would read. A v3 target - requires `baseline.source: file` (requirement 1.8), captured while the - baseline environment's catalog was the stored one. So does a v4 target with - `allow_v3_fallback: true`: enabling the fallback is accepting a v3 - compilation, and by the time one happens the configuration can no longer be - rejected. -2. **`baseline.source: file` does not make v3 non-mutating.** It stops PIACE - from destroying its own input; it does not stop the compiler from writing - the candidate facts and catalog into PuppetDB. Any consumer of PuppetDB - state — reporting, exported resources, inventory, node classification that - reads `facts_environment` — sees the candidate values until the target's - next agent run restores them. - -v3 additionally carries the trusted-fact caveat that motivated PIACE's explicit -API selection in the first place: the request is authenticated by the TLS -client identity, so when the catalog-reader certificate is not the target's -certificate, `$trusted` in manifests or Hiera can yield a non-equivalent -catalog. `puppet-catalog_diff` documents this same limitation. See -[trusted-facts research](../../../docs/research/trusted-facts-in-existing-catalog-diff-tools.md). - -### 7.3 Wire requirements shared by both implementations - -- Every `/puppet/v3/` request requires an explicit `Accept` header. The v3 - routes are served by the compiler's embedded Ruby Puppet request handler, - which rejects a request without one before doing any work, with HTTP 400 and - `"Missing required Accept header"`. The acceptable value is endpoint-specific: - `application/json` for `/puppet/v3/catalog/:certname`, and - `application/octet-stream` for `/puppet/v3/file_content/` — which rejects - `application/json` with HTTP 406. `POST /puppet/v4/catalog` has no such - requirement, being served directly rather than through that handler. -- A v3 catalog response is the catalog document itself. A v4 catalog response - wraps it as `{"catalog": {...}}`. -- The `Accept` header does not select the catalog's rich-data encoding; - `__ptype`-tagged values are returned or not according to the compiler's own - `rich_data` setting, independent of the requested format. - -The behaviour in sections 7.1-7.3 was verified against a deployed OpenVox -compiler and PuppetDB on 2026-08-25. Fixture captures from the specific -compiler and PuppetDB versions in use remain the condition for declaring any -other combination supported. - -## 8. Target-file shape - -The following schema illustrates the required global defaults and per-target -overrides. Exact option names are implementation details, but the represented -configuration is part of the product contract. - -```yaml -version: 1 - -defaults: - candidate: - environment: feature-123 - catalog_api: v4 - facts: - source: puppetdb # puppetdb | file - baseline: - source: file # puppetdb | file - environment: production - file: snapshots/catalogs/{certname}.json - exclude: - - type: File - title: "/var/cache/*" - - type: Notify - title: "*" - impact_estimate: - enabled: true - timeout: 10s - result_limit: 1000 - fail_on_diff: true - redact: - - type: File - parameter: content - -targets: - - certname: web-01.example.test - candidate: - environment: feature-123 - catalog_api: v4 - facts: - source: file - file: snapshots/facts/web-01.example.test.json - baseline: - source: file - environment: production - file: snapshots/catalogs/web-01.example.test.json - exclude: - - type: File - title: "/var/lib/app/cache/*" -``` - -For a development branch, `baseline.source: file` points to a snapshot captured -after the target's main/production environment was deployed. A -`baseline.source: puppetdb` request intentionally means PuppetDB's current -latest catalog, regardless of its environment, and is available only with -`catalog_api: v4` (requirement 1.8, section 7.2). - -The two baseline sources answer different questions, and in CI the difference -matters more than the convenience: - -- **`baseline.source: puppetdb`** compares *what the target last received* - against *what it would receive now*. It is the right baseline for asking - whether a node has drifted from what the deployed code produces, but it - depends on the target having run recently in the baseline environment, and - the comparison mixes code changes with fact changes since that run. -- **`baseline.source: file`**, captured with `piace capture catalog - --environment ` from the same factset, compares - *baseline code now* against *candidate code now* against *identical facts*. - Nothing but the environment differs, so a difference is attributable to the - change under review. This is the better baseline for a CI gate on a code - change, and it does not depend on the target's agent-run schedule. - -## 9.

Naming both forms of one +credential is an error rather than a precedence rule nobody remembers. This is +what lets a services file be committed and read in place by a CI job whose +credential directory did not exist when the file was written. + +### Candidate catalogs come from an existing compiler + +PIACE is an HTTPS client, not a Puppet compiler. CI deploys the candidate +environment to an existing Puppet Server or OpenVox compiler, and PIACE +requests each candidate catalog through that compiler's v3 or v4 catalog API +using a dedicated catalog-reader certificate. That keeps the CLI +dependency-free and air-gap-installable while compiling with the deployed +environment's actual Puppet runtime and code. + +Borrowing the deployed compiler means accepting its persistence behaviour. The +v4 API lets a request disable fact and catalog persistence, and PIACE sets +those fields on every v4 request, so a v4 candidate compilation leaves +PuppetDB untouched. The v3 API has no such control: the compiler saves the +submitted facts and stores the compiled catalog under the candidate +environment. v3 is therefore a degraded path constrained to a file-backed +baseline, not an equivalent one. + +Local fact and catalog snapshots are PIACE envelopes rather than bare Puppet +payloads: they record source, target, environment where applicable, capture +metadata, input identity, and an integrity checksum. A PuppetDB baseline whose +environment differs from the configured baseline environment is rejected. + +### The change assessment stays out of the result document + +The result document is canonically encoded and `schema_version`-tagged so that +identical input catalogs and configuration produce byte-identical artifacts, +and the acceptance suite asserts exactly that. A model-generated change +assessment cannot hold that property: even with sampling pinned, a +provider-side model revision changes the bytes. + +Rather than weaken the invariant to accommodate an advisory feature, the +assessment is a separate artifact with its own `ai_schema_version`, carrying a +SHA-256 checksum of the canonical result document it was derived from. +Embedding it and bumping `schema_version` was rejected because it would turn a +guarantee a reader can state in one sentence into one with an exception list. + +Because the assessment is a pure function of a stored result document, it is +produced by a second command, `piace explain`, rather than inside `compare`. +That leaves `compare`'s configuration surface, dependency surface, failure +modes and service reach unchanged, and it makes the feature runnable and +testable offline against a report some earlier run produced. The cost is one +extra step in a pipeline. + +### The inference service is the one bearer-token exception + +PIACE authenticates to the compiler and PuppetDB exclusively via mTLS, and +`internal/transport` enforces it beyond configuration: `Client` deletes any +`Authorization` header from every request it sends, so a stolen services file +yields nothing usable. Every practical OpenAI-compatible inference service +authenticates with a bearer token, so there is one scoped exception. + +The scope is structural rather than a matter of discipline: the inference +client is its own package, `internal/inference`, and is the only code in PIACE +that sets an `Authorization` header. The token is never written in the +services file; `token_env` and `token_file` reference it, and `https` is the +only accepted scheme. + +The `inference:` section lives in the same services file as the compiler and +puppetdb sections, and the three load independently: a file carrying only +`inference:` is valid for `explain`, which needs no mTLS identity and builds no +compiler or PuppetDB client. What separates a comparison job from an +assessment job is which credentials each is granted, not which file it reads. + +### `change-context` is the only subcommand that invokes git + +`compare` and `explain` contact nothing but the compiler, PuppetDB and the +inference service, and neither runs git. `explain --change` reads a file the +caller produced by any means, so a repository under a different VCS, or a CI +system with no checkout, describes its change by hand. + +`piace change-context` produces that file by exec'ing git, and it is optional. +It exists because the alternative is every adopter hand-writing the same YAML +in shell, and the free-text part of that is the dangerous part: a pull request +title is attacker-supplied, and a CI system that substitutes one into script +text before a shell runs turns it into a command.
