The final edge is +not expanded into another copy of `A@2`. It closes the cycle by pointing to the +existing exact `A@2` node. + +`A@1` and `A@2` are different nodes. Seeing the package name `A` twice is not a +cycle by itself. + +## Exact node identity + +A materialized node is identified by all of the following: + +1. registry identity; +2. organization and package name; +3. exact version; +4. immutable artifact digest. + +The public dependency-graph contract stores the first three fields in +`PackageVersionIdentity` and stores the digest on `ResolvedDependencyNode`. +Zed joins them before cycle reporting or filesystem materialization. + +A graph that omits an artifact digest is rejected. Digests must use canonical +`sha256:<64 lowercase hexadecimal characters>` spelling and cannot be all zero. + +## What is authoritative + +The exact resolved graph is authoritative. Directory shape is not. + +A production materialization accepts a byte-canonical graph whose +`graph_digest` verifies. Roots, nodes, edges, artifact digests, target, enabled +features, registry checkpoints, and lock digest therefore remain explicit and +replayable. A filtered graph projection is rejected because it is not complete +lock authority. + +The local fixture-plan entry point may finalize a graph with no digest. It is +for tests and development fixtures; normal users should supply a verified graph +and let Zed bind its nodes to the content-addressed store. + +## Detection algorithm + +Zed builds a deterministic adjacency map keyed by exact package-version +identity. It then performs an iterative depth-first traversal. + +Each node has one of three states: + +- unseen; +- visiting, with its index in the active path; +- complete. + +An edge to an unseen node descends into that node. An edge to a complete node is +ordinary graph sharing, such as the bottom point of a diamond, and is not a +cycle. An edge to a visiting exact node is a cycle-closing back edge. + +For a back edge, Zed: + +1. records the closed path from the earlier active node through the current + node and back to the target; +2. rotates the path into a canonical deterministic spelling; +3. adds the edge to the materialized graph; +4. does not recursively expand that edge again. + +The traversal uses an explicit frame stack rather than Rust call-stack +recursion. A deep hostile graph therefore cannot cause a recursive stack +overflow. Graph materialization is bounded to 50,000 nodes and 500,000 edges. +Cycle diagnostics are bounded to 4,096 deterministic witnesses so a hostile +strongly connected graph cannot flood the terminal or telemetry pipeline. + +The detector reports deterministic DFS cycle witnesses rather than attempting +to enumerate every mathematically distinct simple cycle. Enumerating every +simple cycle can be exponential. Every cyclic strongly connected region still +produces a witness. + +## Finite symlink layout + +Package payloads remain extracted once in the global content-addressed store. +A project receives a finite overlay: + +```text +project/ + zed_modules/ + / -> exact root node + .zed/versioned-graph/v1/graphs/ + / + / + graph.json + cycles.json + .complete.json + nodes/ + / + node.json + root/ + -> immutable store payload entries + zed_modules/ + / -> exact target node root +``` + +There is one overlay root per exact node and one dependency link per exact edge. +The `B@0 -> A@2` back edge is therefore one symlink to the already-created +`A@2` overlay root. It does not create `A@2/B@0/A@2/...` copies. + +The stable node key includes a readable `org+name@version` prefix plus a hash of +the complete exact identity. Human-readable names remain useful while registry +identity and artifact digest still prevent collisions. + +### Graph digest versus source-binding digest + +`graph_digest` identifies semantic lock authority. It does not include local +filesystem paths. + +The source-binding digest identifies one physical projection of that graph. It +hashes the graph digest plus the canonical local source path and artifact digest +for every node. Moving the store creates another finite generation without +changing graph identity. Repeating a materialization with the same graph and +sources reuses and verifies the existing generation. + +## Atomicity and validation + +Zed stages a complete generation next to its final location, writes canonical +graph and cycle records, writes a completion marker, and atomically renames the +staging directory. Concurrent processes may build the same generation; the +winner publishes it and the loser verifies and reuses it. + +Before an existing generation is reused, Zed verifies: + +- graph and source-binding digests; +- exact canonical graph bytes; +- deterministic cycle records; +- one real node directory per exact node; +- exact node metadata; +- every payload entry is a symlink to the expected immutable source; +- every dependency edge is a symlink to the expected exact target. + +The project-level `zed_modules` root is replaced through a sibling transaction +backup. A failed publication restores the previous root. + +Payload sources and the project must be disjoint. A source containing a +`zed_modules` entry is rejected so a previously materialized dependency tree +cannot be mistaken for immutable package payload. + +## Copy mode and Windows + +A circular graph cannot be naively copied recursively: that recreates the same +subtree forever. A parallel-version graph also cannot be flattened without +losing parent-specific selection. + +The exact-graph command therefore fails closed in copy mode. It never silently +falls back to recursive copying. The ordinary flat installer remains available +for acyclic graphs that select one version per package coordinate. + +On Unix, exact graphs use directory symlinks. On platforms where directory +symlinks are unavailable, exact-graph symlink materialization fails with an +explicit diagnostic. A future Windows implementation must use a reviewed finite +junction/symlink overlay with the same graph and safety invariants; copy fallback +is not acceptable for cycles. + +## Terminal and ORE logging + +Every deterministic cycle witness emits one warning through the Rust SDK from +`github.com/ores-otel/ores.otel.log`. Console output is enabled at the CLI +boundary, so the user sees the exact path and closing edge. + +Structured fields include: + +```text +event = zed.install.circular_dependency +cycle_id = sha256: +path = [exact node labels including version and artifact digest] +closing_from = +closing_to = +target_node_key = +target_artifact_digest = sha256: +resolution = exact-node-symlink +graph_digest = sha256: +materialization_digest = sha256: +``` + +A representative terminal message is: + +```text +circular dependency detected: registry::org/a@2#... -> registry::org/b@0#... -> registry::org/a@2#...; closing edge ... reuses the existing exact node through a symlink +``` + +The warning is evidence of deliberate cycle handling, not a failure by itself. +An incompatible or malformed graph still fails validation. + +## CLI + +Materialize a canonical graph from the configured Zed store: + +```sh +zed --home "$ZED_PKG_HOME" graph materialize \ + --graph exact-resolution.json \ + --project . \ + --mode symlink +``` + +Every artifact digest named by the graph must already exist in the store. Zed +reports the exact missing node and store path instead of fetching or guessing. + +Use an explicit local source plan for an isolated fixture: + +```sh +zed graph materialize \ + --plan tests/fixtures/versioned-cycle/plan.json \ + --project "$TMPDIR/cycle-project" +``` + +The command prints ORE warnings as cycles are recognized and prints one JSON +materialization report as its final stdout line. + +## Verification + +Product gates: + +```sh +cargo fmt --all --check +cargo test --locked --lib versioned_graph +cargo test --locked --test versioned_dependency_cycles -- --nocapture +cargo test --locked --all-targets +cargo clippy --locked --all-targets -- -D warnings +``` + +The integration test exercises the real `zed` binary, the four-node example, +visible ORE output, finite node and edge counts, payload symlinks, exact back-edge +reuse, idempotent replay, content-addressed store binding, and copy-mode refusal. + +`zed-pkg-test/zed-pkg-e2e` independently reconstructs the same graph outside the +product crate and runs the public executable in normal and replay modes. + +## Current boundary and next integration step + +This implementation provides the exact-version graph validation, +materialization, diagnostics, and public CLI substrate. The ordinary +manifest-driven solver and `.zpkg.lock` v1 still intentionally carry one selected +version per `org/name`. + +Automatic fallback from an unsatisfiable one-version solve to an isolated +multi-version solve requires a separately reviewed lockfile extension that +persists exact roots and edges. That extension must reuse this materializer; it +must not invent a second directory-derived graph or weaken frozen replay.

DEN-3488 v0.3.0 integration receipt + +## Immutable composition + +The finite exact-version circular-dependency implementation has been reconciled with released `zed-cli` v0.3.0 through a true two-parent merge. + +- v0.3.0 main: `b38a1edd2ca7852bc81ad2e01e2989f44009e93e` +- pre-integration DEN-3488 head: `1aa85862e897a79b084b2a1be908e6b7704f7664` +- semantic merge:

The effective product delta is limited to the exact graph implementation, public graph command, focused workflow/tests, documentation, the immutable ORES logger dependency, and its regenerated lock graph. + +## Semantic conflict decisions + +- Preserve v0.3.0 package version, current `zed-interfaces`, `zed-lock`, `flags-2-env`, CLI, mirror, publication, and release behavior. +- Add `next_loggers` only for structured, terminal-visible circular-dependency diagnostics. +- Keep the current install graph's registry ownership; an obsolete test-only import exposed by all-target compilation was removed rather than suppressing the warning. +- Keep ordinary `.zpkg.lock` v1 one-version-per-coordinate semantics. The new materializer consumes an explicit exact resolved graph; automatic solver fallback remains a separate contract migration. +- Preserve the already-merged, self-hosted Claritas graph visualization in `zed-web-server.rs`; this CLI change does not add a duplicate browser runtime. + +## Exact validation + +Bounded workflow run `33909111236` completed successfully before publishing the regenerated lockfile and deleting itself. It proved: + +- `cargo generate-lockfile` resolved `zed-cli` 0.3.0; +- the lock includes `oresoftware-next-loggers` at exact revision `9e28eca35b4c3f283cde933ae645216972d2f3e3`; +- `cargo fmt --all -- --check` passed; +- `cargo check --locked --all-targets` passed; +- the complete `versioned_graph` unit suite passed; +- the public graph-materialization parser regression passed; +- the executable finite-cycle integration suite passed; +- strict all-target Clippy passed with only the three narrowly documented current-main lint exceptions used by the original certified DEN-3488 workflow. + +The one-shot workflow is absent from the review tree. This receipt commit intentionally triggers the permanent repository pull-request workflows on the exact current product head. + +## Promotion boundary + +Do not merge based solely on this receipt. Every permanent workflow on the exact current PR head must be terminal and green, independent review must be complete, and companion `zed-pkg-test` acceptance must pin the resulting immutable product revision. Pending, skipped, canceled, older-head, or zero-job runs are not passing evidence.
