operator, I can run an upgrade command for an installed external rules pack so I can fetch the newest available version and keep my project configuration pinned to that downloaded version. + +**Why this priority**: Rules changes directly affect governance behavior and policy checks, so keeping these packs current is high-value and time-sensitive. + +**Independent Test**: Can be fully tested by running the upgrade command for a rules pack that has a newer remote version and verifying the local cached pack and configuration reference both move to the same new version. + +**Acceptance Scenarios**: + +1. **Given** a project references an external rules pack, **When** the operator runs `steergen rules-pack upgrade` for that pack without specifying a tag, **Then** the command refreshes the entire cached contents for that targeted pack reference and updates the project configuration to pin the downloaded version. +2. **Given** a project references an external rules pack, **When** the operator runs `steergen rules-pack upgrade` with a specific tag, **Then** the existing local copy for that pack reference is purged, the requested version is downloaded, and the configuration is pinned to that exact requested version. +3. **Given** the requested upgrade cannot be retrieved, **When** the command finishes, **Then** the prior pinned reference remains unchanged and the operator receives a clear failure message. + +--- + +### User Story 2 - Upgrade a Template Pack with the Same Workflow (Priority: P2) + +As a CLI operator, I can perform the same upgrade workflow for external template packs so pack maintenance is consistent across rules and templates. + +**Why this priority**: Template packs are a core content dependency but are typically updated less frequently than rules packs. + +**Independent Test**: Can be fully tested by running the upgrade command path for template packs and verifying identical behavior for purge, refetch, and version pin update. + +**Acceptance Scenarios**: + +1. **Given** a project references an external template pack, **When** the operator runs the template-pack upgrade subcommand without a tag, **Then** the command refreshes the entire cached contents for that targeted pack reference and pins the configuration to the downloaded version. +2. **Given** a project references an external template pack, **When** the operator runs the template-pack upgrade subcommand with a specific tag, **Then** the command purges the existing local copy for that reference, fetches the requested tag, and pins the configuration to that tag. + +--- + +### User Story 3 - Safe, Predictable Upgrade Operations (Priority: P3) + +As a CLI operator, I need upgrade operations to be deterministic and safe so failed or malformed upgrade attempts do not silently alter project state. + +**Why this priority**: Operator trust depends on predictable outcomes, especially when remote sources are unavailable or user input is malformed. + +**Independent Test**: Can be tested by running upgrades with invalid tags, unavailable sources, and malformed input and verifying fail-closed behavior plus diagnostic output. + +**Acceptance Scenarios**: + +1. **Given** an operator provides an invalid tag or malformed pack identifier, **When** upgrade is executed, **Then** the command fails with actionable diagnostics and makes no configuration changes. +2. **Given** two consecutive upgrade runs with the same explicit tag, **When** both complete successfully, **Then** the resulting pinned reference and local pack version are identical after each run. + +--- + +### Edge Cases + +- Upgrade command is invoked for a pack reference that is not present in the project configuration. +- Upgrade command is invoked without a required pack selector. +- Upgrade command receives a selector that matches multiple pack references. +- Upgrade command receives a selector that is not a valid canonical composite identifier. +- Local cache contains manual or unexpected file changes before upgrade. +- A requested explicit tag exists remotely but download or extraction fails midway. +- Latest-version resolution returns no valid releases. +- Local purge succeeds but remote fetch fails; command must not write a new pinned reference. +- Previous cache snapshot restoration fails after fetch failure. +- No explicit tag/ref is provided and the system cannot determine whether the local cache is stale; the full targeted cache must still be refreshed. +- Existing configuration contains multiple references to the same source with different tags; only targeted reference is updated. +- Upgrade is re-run immediately after success; no unintended drift occurs. + +### Security & Misuse Cases *(mandatory)* + +- How does the system handle malicious, adversarial, or malformed input? +- What prompt-injection-style payloads or instruction-conflict content could appear in input, and how must they be treated as inert data? +- What are the trust boundaries and how are unsafe operations prevented by default? +- Which failure modes must fail closed to avoid security impact? + +- Pack identifiers, tags, and repository metadata from user input MUST be validated and treated as untrusted input. +- Remote pack metadata and release labels MUST be treated as inert data, not executable instructions. +- Upgrade operations MUST be constrained to approved local pack storage locations and project configuration files. +- If validation, purge, fetch, or pin update steps fail, the command MUST fail closed and preserve the previous pinned reference. + +## Requirements *(mandatory)* + +### Functional Requirements + +- **FR-001**: The CLI MUST provide an `upgrade` subcommand under the rules-pack command group. +- **FR-002**: The CLI MUST provide an equivalent `upgrade` subcommand under the template-pack command group. +- **FR-003**: The upgrade subcommand MUST accept an optional explicit tag argument. +- **FR-004**: If no explicit tag is provided, the upgrade subcommand MUST refresh the entire cached contents for the targeted pack reference by purging and refetching it, even when local staleness cannot be determined. +- **FR-005**: If an explicit tag is provided, the upgrade subcommand MUST purge the currently cached copy for the targeted pack reference and fetch the requested tag. +- **FR-006**: On successful fetch, the system MUST update the corresponding pack reference in `steergen.config.yaml` to pin the downloaded version. +- **FR-007**: The upgrade workflow MUST support external rules packs and external template packs with equivalent behavior and operator-facing semantics. +- **FR-008**: If any upgrade step fails, the system MUST leave `steergen.config.yaml` unchanged for the targeted reference. +- **FR-009**: The command MUST return a non-zero exit status for failed upgrades and a zero exit status for successful upgrades. +- **FR-010**: The command output MUST identify whether the operation targeted latest-version resolution or a specific tag, and must report the final pinned version on success. +- **FR-011**: The command MUST validate tag and reference input and reject malformed values before attempting remote retrieval. +- **FR-012**: The command MUST not modify unrelated pack references in `steergen.config.yaml`. +- **FR-013**: The upgrade subcommand MUST require an explicit canonical composite selector (source plus path or entry key) for the target pack reference and MUST fail when the selector is missing. +- **FR-014**: If the provided selector matches zero or multiple references, the command MUST fail with diagnostics and MUST not modify configuration or cache. +- **FR-015**: On successful upgrade, the pinned reference format in `steergen.config.yaml` MUST include both the resolved tag and the immutable commit SHA for that resolved version. +- **FR-016**: The upgrade workflow MUST treat the targeted local pack cache as disposable and MUST fully purge and replace it during refresh. +- **FR-017**: The command MUST NOT merge, preserve, or restore local cache file edits from the pre-upgrade cache state after a successful upgrade. +- **FR-018**: If fetch fails after purge, the command MUST restore the previous cache snapshot for the targeted pack reference and MUST keep `steergen.config.yaml` unchanged. +- **FR-019**: If snapshot restoration also fails, the command MUST return a non-zero exit status and emit diagnostics that explicitly identify both fetch failure and rollback failure. +- **FR-020**: The command MUST reject selectors that do not conform to the canonical composite selector format before any purge or fetch steps begin. +- **FR-021**: Canonical selector syntax MUST be `source|pathOrEntryKey`, where `source` is `github:{owner}/{repo}` and `pathOrEntryKey` is non-empty. +- **FR-022**: Selector parsing MUST trim surrounding whitespace and reject empty selector components or unescaped pipe delimiters with explicit validation diagnostics. +- **FR-023**: The selector delimiter MUST be a single unescaped pipe (`|`). A literal pipe within selector components MUST be escaped as `\|`. +- **FR-024**: Parsing MUST split on the first unescaped delimiter, unescape `\|` after split, and reject trailing backslash, empty escape sequences, or multiple unescaped delimiters with deterministic diagnostics. + +Selector examples: +- Valid: `github:owner/repo|packs/security` +- Valid: `github:owner/repo|team\|security` +- Invalid: `github:owner/repo|packs|security` +- Invalid: `github:owner/repo|` + +### Non-Functional Requirements *(mandatory)* + +- **NFR-001 (Security)**: Upgrade input and remote metadata MUST be validated as untrusted data; invalid or suspicious values MUST be rejected before state changes. +- **NFR-002 (Determinism/Correctness)**: Re-running upgrade with the same explicit tag and same source state MUST yield the same final pinned tuple (tag plus commit SHA). +- **NFR-003 (Performance)**: For packs under 100 MB and healthy network conditions, 95% of upgrade operations MUST complete within 60 seconds. +- **NFR-004 (Robustness)**: Any failure during purge, resolution, retrieval, rollback, or pin update MUST produce actionable diagnostics and fail without partial configuration updates. +- **NFR-005 (Usability)**: Command help and output MUST clearly communicate usage, canonical selector format, targeted pack type, selected version source (explicit vs latest), and final outcome. +- **NFR-006 (Documentation)**: User documentation MUST include upgrade command usage for rules and template packs, including explicit-tag and latest-version examples. + +### Key Entities *(include if feature involves data)* + +- **Pack Reference**: A project configuration entry that identifies an external rules or template pack source and its pinned version. +- **Upgrade Request**: Operator-supplied intent to upgrade a specific pack reference identified by canonical composite selector, optionally including an explicit tag. +- **Resolved Version**: The selected version represented as a tuple of resolved tag and immutable commit SHA, used as the new pinned value. +- **Upgrade Result**: The observable outcome of an upgrade attempt, including success/failure, selected version mode, diagnostics, and resulting pin state. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: 100% of successful upgrade runs for rules packs result in the targeted project reference being pinned to the downloaded version. +- **SC-002**: 100% of successful upgrade runs for template packs result in the targeted project reference being pinned to the downloaded version. +- **SC-003**: In failure test scenarios (invalid tag, missing release, retrieval failure), 100% of runs leave the targeted configuration reference unchanged. +- **SC-004**: In a structured acceptance exercise with at least 10 operators, at least 90% MUST complete one latest-mode and one explicit-tag upgrade in a single command attempt without consulting source code. + +### Test Strategy Expectations *(mandatory)* + +- Define core invariants to validate with property-based testing. +- Specify which example-based tests are still needed and why properties are insufficient there. +- Where practical, define golden, integration, and end-to-end fixtures using plausible real-world constitution or steering rules rather than toy placeholders. +- Define required security test scenarios, including malicious input and prompt-injection-style payload validation. + +- Property invariants: successful upgrade always results in a pin that matches the downloaded version; failed upgrade never changes the prior pin; failed fetch after purge restores prior cache snapshot; repeated explicit-tag upgrades converge to identical state. +- Example-based tests: explicit tag success/failure paths, latest resolution success/failure paths, and cross-command parity between rules-pack and template-pack upgrade behavior. +- Integration fixtures: project fixtures with external rules and template pack references, including multi-pack configurations where only one target should change. +- Security tests: malformed tag input, path-like injection payloads in tag or source fields, and hostile remote metadata strings treated strictly as inert text. +- Acceptance tests: run a scripted operator task set (>=10 participants) and record first-attempt success rates for latest-mode and explicit-tag flows. + +## Assumptions + +- Operators have permission to modify local project configuration files and local pack cache content. +- External source endpoints expose version identifiers that can be used for explicit tag retrieval and latest-version resolution. +- This feature targets upgrade behavior only; new source registration flows remain out of scope. +- Existing pull/fetch mechanisms for external packs are reused as the retrieval basis for upgrade operations. diff --git a/specs/003-upgrade-pack-refs/tasks.md b/specs/003-upgrade-pack-refs/tasks.md new file mode 100644 index 0000000..0f5129f --- /dev/null +++ b/specs/003-upgrade-pack-refs/tasks.md @@ -0,0 +1,217 @@ +# Tasks: Upgrade External Pack References + +**Input**: Design documents from `/specs/003-upgrade-pack-refs/` +**Prerequisites**: `plan.md` (required), `spec.md` (required), `research.md`, `data-model.md`, `contracts/`, `quickstart.md` + +**Tests**: Tests are MANDATORY.
