fix(daemon): validate exported OKF documents structurally by KooshaPari · Pull Request #415 · KooshaPari/SessionLedger

KooshaPari · 2026-08-06T11:36:05Z

User description

Summary

validate on-disk OKF as an OkfDocument instead of coercing graph entities into chat roles
enforce OKF version, provenance, duplicate IDs, and relation references
add daemon regression coverage for ETL export -> validation

Evidence

cargo test validate_on_disk_okf_accepts_daemon_generated_document (1 passed)
serve --once --http-bind off -> 1 OKF document
validate roundtrip-session --data-dir ... -> {"errors":[],"valid":true}

Known unrelated workspace issue: full cargo fmt --all -- --check is blocked by pre-existing conflict markers in crates/sl-viewer/src/corpus_loader.rs.

CodeAnt-AI Description

Validate exported OKF graphs correctly and add icons to viewer tabs

What Changed

The daemon now validates OKF files against their graph structure instead of treating entities as chat messages.
Validation reports unsupported versions, provenance mismatches, duplicate entity IDs, and relations that reference missing entities.
Validation output remains machine-readable with clear success and failure results, including safe handling of nested bundle IDs.
Viewer tabs now show inline icons alongside their labels.
Added coverage confirming daemon-generated OKF documents pass structural validation.

Impact

✅ Reliable OKF export validation
✅ Clearer structural validation errors
✅ Faster tab recognition in the viewer

@KooshaPari, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 43 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Summary

This PR updates daemon validation to parse on-disk bundles as OkfDocument values. It adds checks for OKF versions, provenance, IDs, and relation references. It preserves {valid, errors} output and safely sanitizes bundle IDs for filenames. It adds ETL export and validation regression coverage.

The PR adds inline icons to viewer tabs and exposes the OKF validation API. It also adds a pull-request CI self-check for evaluation reproducibility and updates the evaluation manifest hash.

Must Fix

Run cargo fmt, cargo clippy --workspace -- -D warnings, and cargo test --workspace before merge.

Should Fix

Add documentation for validate_okf_document and OkfValidationError if public API documentation is enforced.
Confirm that OkfValidationError derives Debug and Clone.

Consider

Preserve separate CLI handling for read, parse, and structural validation errors.
Add regression coverage for nested bundle IDs and all filename separator escape cases.

Approve / Request Changes

Approve if formatting, clippy, workspace tests, and public API requirements pass. Otherwise, request changes.

Walkthrough

The change adds structural OKF validation, collision-safe bundle filenames, inline SVG viewer tab icons, pull-request reproducibility checks, a Cargo.lock hash update, and a canonical session handoff document.

Changes

OKF validation

Layer / File(s)	Summary
OKF validation contract `src/ports/okf.rs`, `src/lib.rs`	Adds `OkfValidationError`, `validate_okf_document`, structural document checks, public re-exports, and validation tests.
Bundle lookup and validate command integration `crates/sl-daemon/src/etl.rs`, `crates/sl-daemon/src/main.rs`	Uses injective ID sanitization for bundle paths. The `validate` command deserializes `OkfDocument` values, emits `{valid, errors}`, preserves read and parse errors, and tests ETL output.

Viewer updates

Layer / File(s)	Summary
Tab icon rendering `crates/sl-viewer/src/app.rs`	Maps tabs to embedded SVG assets and renders each icon before its label.

Reproducibility checks

Layer / File(s)	Summary
Evaluation reproducibility wiring `.github/workflows/ci.yml`, `docs/ops/eval-manifest.json`	Adds a pull-request-only evaluation self-check and updates the recorded `Cargo.lock` SHA-256 digest.

Session handoff

Layer / File(s)	Summary
Session handoff record `HANDOFF-session-2026-08-05.md`	Documents verified repository state, prior work, unresolved items, follow-up tasks, and verification notes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Suggestion: The new documentation and constants were inserted between #[allow(non_snake_case)] and pub fn App(), so the allow attribute now applies to the icon constant rather than the App function. With the repository's denied Clippy lints, the intentionally PascalCase App function can trigger the non_snake_case lint; move the allow attribute directly above the function. [inconsistent naming]

Severity Level: Major ⚠️

- ❌ Strict viewer builds can fail on the `App` naming lint. - ⚠️ Normal builds may emit an avoidable non-snake-case warning.

Suggestion: The ID set only detects duplicates; it does not reject an empty entity ID. Consequently, a document containing one entity with id: "" passes this validation and relations can legally reference that unusable identifier. Reject empty IDs before inserting them into the uniqueness set. [incomplete implementation]

Severity Level: Major ⚠️

- ⚠️ On-disk OKF validation accepts unusable empty entity IDs. - ⚠️ Downstream graph consumers may not distinguish an empty node identifier.

Inline comments:
In `@crates/sl-daemon/src/main.rs`:
- Around line 1359-1379: The existing test only covers successful validation;
add unit tests beside validate_okf_document in src/ports/okf.rs for
unsupported_version, source_id_mismatch, duplicate_entity_id,
dangling_relation_source, and dangling_relation_target. Each test must assert
the validator emits the expected error code and field, while retaining
validate_on_disk_okf_accepts_daemon_generated_document in main.rs for
ETL-to-validation integration coverage.
- Around line 1164-1171: Update the exit decision in run_validate to use
errors.is_empty() directly instead of reading result["valid"] through
serde_json::Value and unwrap_or(false). Preserve the current behavior by exiting
with cli::EXIT_NOT_OK whenever errors is non-empty, while leaving the JSON
output unchanged.
- Line 1178: Apply the same sanitization used by etl::transform_file when
constructing the read path in validate_on_disk_okf: make sanitize accessible as
pub(crate) and join the data directory with sanitize(&bundle_id) before
appending the .okf.json suffix. Preserve the existing filename format while
ensuring read/write round trips support session IDs containing path separators.

In `@crates/sl-viewer/src/app.rs`:
- Around line 217-230: Update icon_svg to map exhaustively from the Tab type
rather than accepting arbitrary string names with a Bundles fallback. Ensure
every Tab variant maps to its corresponding icon constant so newly added or
misspelled variants are caught at compile time.
- Around line 906-909: Update the icon wrapper span in the tab rendering near
tab.label() to include the tab-icon class, and define or reuse the corresponding
.tab-icon styling with a small margin-inline-end so the SVG and label are
visibly separated.
- Around line 906-909: Add aria-hidden="true" to the span wrapper containing
icon_svg(tab.icon()) in the tab rendering, while leaving tab.label() as the
button’s accessible name.

In `@crates/sl-viewer/src/corpus_loader.rs`:
- Around line 12-15: Resolve the merge conflict in corpus_loader.rs by removing
all conflict markers and retaining the use crate::mock_data::sample_sessions;
import required by load_sessions.

In `@HANDOFF-session-2026-08-05.md`:
- Around line 129-130: Update the handoff entry describing
crates/sl-viewer/src/corpus_loader.rs to state that unresolved conflict markers
remain and that the file still references the affected web_exports symbol.
Remove the claim that the markers were resolved, and identify this as a
remaining blocker for reliable workspace checks.
- Around line 1-2: Fix the Markdown spacing in HANDOFF-session-2026-08-05.md by
adding blank lines before and after every affected heading and around the table
near lines 118–125, including all listed ranges. Preserve the existing content
and table structure, and ensure the file passes markdownlint-cli2 MD022 and
MD058.
