Kirby Ross" Date: Fri, 26 Sep 2025 22:46:37 -0700 Subject: [PATCH 03/56] refactor(git): Introduce Git repository port abstraction Decouple core Git-dependent application logic (like cache and journal services) from the underlying library (`libgit2`) using the Port and Adapter (Hexagonal) pattern. The core change is the introduction of the abstract `gm_git_repository_port_t` interface (`core/include/gitmind/ports/`) which defines abstract methods for repository-scoped operations, including tree building, object reading, commit creation, and reference updates. A concrete adapter, `gm_libgit2_repository_port`, is implemented to fulfill this contract using `libgit2`. The application context (`gm_context_t`) is updated to hold and manage this new abstract port, replacing direct dependencies on `libgit2` for these high-level operations across the application (e.g., in `apps/cli/main.c` and `benchmarks/`). Additionally, `gm_cache_meta_t` is updated to include `cache_tip_oid` to align cache management with the new port-based commit and reference update capabilities. This isolation significantly improves modularity and testability. --- apps/cli/main.c | 30 + benchmarks/wildebeest_stampede.c | 12 + .../adapters/git/libgit2_repository_port.h | 27 + core/include/gitmind/cache.h | 1 + core/include/gitmind/context.h | 4 + .../gitmind/ports/git_repository_port.h | 162 +++++ .../adapters/git/libgit2_repository_port.c | 573 ++++++++++++++++++ core/src/app/cache/cache_rebuild_service.c | 181 +++--- core/src/cache/builder.c | 4 +- core/src/cache/cache_internal.h | 3 - core/src/cache/query.c | 275 ++++----- core/src/cache/tree_builder.c | 277 --------- .../fakes/git/fake_git_repository_port.c | 327 ++++++++++ .../fakes/git/fake_git_repository_port.h | 69 +++ core/tests/unit/test_cache_branch_limits.c | 9 + core/tests/unit/test_cache_meta.c | 10 + core/tests/unit/test_cache_query.c | 9 + core/tests/unit/test_journal_mixed_cbor.c | 10 + meson.build | 2 +- 19 files changed, 1432 insertions(+), 553 deletions(-) create mode 100644 core/include/gitmind/adapters/git/libgit2_repository_port.h create mode 100644 core/include/gitmind/ports/git_repository_port.h create mode 100644 core/src/adapters/git/libgit2_repository_port.c delete mode 100644 core/src/cache/tree_builder.c create mode 100644 core/tests/fakes/git/fake_git_repository_port.c create mode 100644 core/tests/fakes/git/fake_git_repository_port.h diff --git a/apps/cli/main.c b/apps/cli/main.c index 784ca350..55536901 100644 --- a/apps/cli/main.c +++ b/apps/cli/main.c @@ -8,6 +8,7 @@ #include "cli_runtime.h" #include "gitmind/adapters/fs/posix_temp_adapter.h" +#include "gitmind/adapters/git/libgit2_repository_port.h" #include "gitmind/constants_internal.h" @@ -183,6 +184,19 @@ static int init_context(gm_context_t *ctx, gm_output_level_t level, memset(ctx, 0, sizeof(gm_context_t));

Kirby Ross" Date: Fri, 26 Sep 2025 22:57:59 -0700 Subject: [PATCH 04/56] refactor(git): Abstract commit tree size calculation to port The commit refactors the calculation of a Git commit's total tree size, moving the concrete `libgit2` implementation into the abstract `gm_git_repository_port_t` interface. This change: * Adds `commit_tree_size` to `gm_git_repository_port_vtbl_t` and provides a concrete recursive implementation (`tree_size_recursive`) in the `libgit2` adapter. * Updates `gm_cache_stats` to use this new port method via `gm_git_repository_port_commit_tree_size` to determine the actual cache size. * Deletes the now redundant `core/src/cache/tree_size.c` and `core/src/cache/cache_internal.h` files, removing the direct `libgit2` dependency from the cache core. This improves architectural modularity and isolation between the core application logic and the Git library adapter. --- core/include/gitmind/cache.h | 4 +- .../gitmind/ports/git_repository_port.h | 14 +++ .../adapters/git/libgit2_repository_port.c | 99 +++++++++++++++++++ core/src/cache/cache_internal.h | 16 --- core/src/cache/query.c | 50 +++------- core/src/cache/tree_size.c | 93 ----------------- .../fakes/git/fake_git_repository_port.c | 17 ++++ core/tests/unit/test_cache_tree_size.c | 34 ++++++- meson.build | 1 - 9 files changed, 176 insertions(+), 152 deletions(-) delete mode 100644 core/src/cache/cache_internal.h delete mode 100644 core/src/cache/tree_size.c diff --git a/core/include/gitmind/cache.h b/core/include/gitmind/cache.h index a0476924..1c915c77 100644 --- a/core/include/gitmind/cache.h +++ b/core/include/gitmind/cache.h @@ -120,8 +120,8 @@ GM_NODISCARD int gm_cache_stats(gm_context_t *ctx, const char *branch, uint64_t */ void gm_cache_result_free(gm_cache_result_t *result); -/* Internal functions have been moved to a private header to avoid exposing - * non-public API via umbrella headers.

This change: * Removes all direct `libgit2` headers and types (`git_repository`, `git_oid`, `git_commit`, etc.) from `core/src/journal/writer.c`. * Switches `journal_ctx_t` to use the abstract `gm_git_repository_port_t`. * Updates `get_current_branch` and `resolve_branch_name` to use the existing `gm_git_repository_port_head_branch` method. Subsequent commits will introduce new port methods for tree, commit, and reference creation to fully port the writing logic. --- core/src/journal/writer.c | 50 +++++++++++---------------------------- 1 file changed, 14 insertions(+), 36 deletions(-) diff --git a/core/src/journal/writer.c b/core/src/journal/writer.c index 37a4ef64..5a434244 100644 --- a/core/src/journal/writer.c +++ b/core/src/journal/writer.c @@ -12,12 +12,6 @@ #include "gitmind/security/memory.h" #include -#include -#include -#include -#include -#include -#include #include #include @@ -36,8 +30,8 @@ /* Journal writer context */ typedef struct { - git_repository *repo; - git_oid empty_tree_oid; + gm_git_repository_port_t *repo_port; + gm_oid_t empty_tree_oid; char ref_name[REF_NAME_BUFFER_SIZE]; } journal_ctx_t; @@ -50,7 +44,10 @@ typedef struct { /* Initialize journal context */ static int journal_init(journal_ctx_t *jctx, gm_context_t *ctx, const char *branch) { - jctx->repo = (git_repository *)ctx->git_repo; + if (ctx->git_repo_port.vtbl == NULL) { + return GM_ERR_INVALID_STATE; + } + jctx->repo_port = &ctx->git_repo_port; /* Parse empty tree OID */ if (git_oid_fromstr(&jctx->empty_tree_oid, EMPTY_TREE_SHA) < 0) { @@ -68,35 +65,16 @@ static int journal_init(journal_ctx_t *jctx, gm_context_t *ctx, } /* Get current branch name */ -static int get_current_branch(git_repository *repo, char *branch_name, +static int get_current_branch(gm_git_repository_port_t *port, char *branch_name, size_t len) { - git_reference *head = NULL; - const char *name; - int error; - - /* Get HEAD reference */ - error = git_repository_head(&head, repo); - if (error < 0) { - return GM_ERR_UNKNOWN; - } - - /* Get branch name */ - name = git_reference_shorthand(head); - if (!name) { - git_reference_free(head); + gm_result_void_t result = + gm_git_repository_port_head_branch(port, branch_name, len); + if (!result.ok) { + if (result.u.err != NULL) { + gm_error_free(result.u.err); + } return GM_ERR_UNKNOWN; } - - /* Copy branch name */ - size_t name_len = strlen(name); - if (name_len >= len) { - git_reference_free(head); - return GM_ERR_BUFFER_TOO_SMALL; - } - gm_memcpy_safe(branch_name, len, name, name_len); - branch_name[name_len] = '\0'; - - git_reference_free(head); return GM_OK; } @@ -230,7 +208,7 @@ static int resolve_branch_name(gm_context_t *ctx, char *branch, return GM_OK; } - return get_current_branch(ctx->git_repo, branch, branch_len); + return get_current_branch(&ctx->git_repo_port, branch, branch_len); } static int flush_journal_batch(journal_ctx_t *jctx, const uint8_t *buffer, From 063664d76650b182d6e60ec36ea7f5f52104e24f Mon Sep 17 00:00:00 2001 From: "J.

Key improvements: 1. **Port Clarity Refactoring:** * **Filesystem Paths:** Renamed generic path segment arguments (`s1`, `s2`, etc.) in the `gm_fs_temp_port_path_join` function across its declaration and implementations (`fs_temp_port.h`, `posix_temp_adapter.c`, `fake_fs_temp_port.c`) to descriptive names like **`component1`**, **`component2`**, etc. * **Git Walk Callback:** Renamed the `walk_commits` callback parameter from `cb` to **`visit_callback`** in the `git_repository_port` interface and the `libgit2` adapter. 2. **Enhanced Fake Git Repository Port:** * Introduced new internal structures (`gm_fake_git_ref_entry_t`, `gm_fake_git_commit_entry_t`) to allow the fake port to store and serve mocked Git history, including commit **OIDs** and **messages**, indexed by reference. * Added public functions (`gm_fake_git_repository_port_set_head_branch`, `gm_fake_git_repository_port_add_ref_commit`) for tests to **programmatically define history**. * Implemented full functionality for `fake_head_branch`, `fake_walk_commits`, and `fake_commit_read_message` using this new mocked state, ensuring that components (like the cache and journal) can now be thoroughly unit tested without skipping Git logic seams. 3. **Header Tidy:** Replaced a direct `#include ` with a **forward declaration** (`typedef struct git_repository git_repository;`) in `libgit2_repository_port.h`, reducing build time dependencies. --- AGENTS.md | 8 +- .../adapters/git/libgit2_repository_port.h | 4 +- core/include/gitmind/ports/fs_temp_port.h | 20 +- .../gitmind/ports/git_repository_port.h | 8 +- core/src/adapters/fs/posix_temp_adapter.c | 24 +- .../adapters/git/libgit2_repository_port.c | 10 +- core/tests/fakes/fs/fake_fs_temp_port.c | 12 +- .../fakes/git/fake_git_repository_port.c | 242 ++++++++++++++++-- .../fakes/git/fake_git_repository_port.h | 28 ++ 9 files changed, 302 insertions(+), 54 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index c1c15019..cbcfbf60 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -417,9 +417,11 @@ See archives under `docs/activity/` for older logs. ### 2025-09-27 - Routed cache metadata, query, and journal flows through `gm_git_repository_port`;

Kirby Ross" Date: Sat, 27 Sep 2025 01:16:54 -0700 Subject: [PATCH 10/56] This diff implements a significant refactoring effort to move Git blob identity resolution from a legacy shim (ctx->git_ops) to the new, preferred gm_git_repository_port interface. This change advances the decoupling of core logic from the underlying libgit2 implementation. This diff implements a significant refactoring effort to move Git blob identity resolution from a legacy shim (ctx->git_ops) to the new, preferred gm_git_repository_port interface. This change advances the decoupling of core logic from the underlying libgit2 implementation. Core Changes: Porting Blob Resolution to the Git Port Port Interface Addition (core/include/gitmind/ports/git_repository_port.h): A new function, gm_git_repository_port_resolve_blob_at_head, is added to the gm_git_repository_port_vtbl_t structure. This function is responsible for looking up the Object ID (gm_oid_t) of a file given its path at the repository's current HEAD. libgit2 Implementation (core/src/adapters/git/libgit2_repository_port.c): The resolve_blob_at_head_impl is implemented using libgit2 functions (git_repository_head, git_commit_lookup, git_tree_entry_by_path) to resolve the blob OID. It introduces a helper function, open_blob_entry, to consolidate the common logic for looking up a tree entry from a commit. Edge Module Refactor (core/src/edge/attributed.c and core/src/edge/edge.c): The core gm_edge_create and gm_edge_attributed_create functions are updated: The deprecated Git shim is removed. A new helper, resolve_blob_identity, is introduced, which calls the new port function (gm_git_repository_port_resolve_blob_at_head). This helper not only retrieves the canonical gm_oid_t but also automatically populates the legacy src_sha/tgt_sha arrays by copying the raw OID bytes. This simplifies the creation functions and maintains compatibility with older fields during the transition. Testing Framework Update The unit test environment is substantially modified to support the new port-based logic: Fake Port Enhancement: The fake port (core/tests/fakes/git/fake_git_repository_port.h/.c) gains new functions (gm_fake_git_repository_port_add_blob_mapping, fake_resolve_blob_at_head) that allow tests to pre-configure a map of file paths to expected blob OIDs, providing a realistic mock of Git resolution. Test Refactoring (core/tests/unit/test_edge.c): The previous custom mock function (mock_resolve_blob) for SHA resolution is removed. The test_edge_create_success unit test now uses the gm_fake_git_repository_port_t to set up the expected OIDs for "src/a.c" and "src/b.c" before calling the gm_edge_create API. Build System: meson.build is updated to include the source file for the fake Git repository port (core/tests/fakes/git/fake_git_repository_port.c) when building the test_edge executable. Miscellaneous The function gm_snprintf in core/include/gitmind/security/string.h is changed from static to static inline to potentially improve performance by allowing the compiler to substitute the function body at the call site. The AGENTS.md log is updated to reflect the completion of this feature, confirming that edge creation now relies on the gm_git_repository_port.This diff implements a significant refactoring effort to move Git blob identity resolution from a legacy shim (ctx->git_ops) to the new, preferred gm_git_repository_port interface.

Core Changes: Porting Blob Resolution to the Git Port Port Interface Addition (core/include/gitmind/ports/git_repository_port.h): A new function, gm_git_repository_port_resolve_blob_at_head, is added to the gm_git_repository_port_vtbl_t structure. This function is responsible for looking up the Object ID (gm_oid_t) of a file given its path at the repository's current HEAD. libgit2 Implementation (core/src/adapters/git/libgit2_repository_port.c): The resolve_blob_at_head_impl is implemented using libgit2 functions (git_repository_head, git_commit_lookup, git_tree_entry_by_path) to resolve the blob OID. It introduces a helper function, open_blob_entry, to consolidate the common logic for looking up a tree entry from a commit. Edge Module Refactor (core/src/edge/attributed.c and core/src/edge/edge.c): The core gm_edge_create and gm_edge_attributed_create functions are updated: The deprecated Git shim is removed. A new helper, resolve_blob_identity, is introduced, which calls the new port function (gm_git_repository_port_resolve_blob_at_head). This helper not only retrieves the canonical gm_oid_t but also automatically populates the legacy src_sha/tgt_sha arrays by copying the raw OID bytes. This simplifies the creation functions and maintains compatibility with older fields during the transition. Testing Framework Update The unit test environment is substantially modified to support the new port-based logic: Fake Port Enhancement: The fake port (core/tests/fakes/git/fake_git_repository_port.h/.c) gains new functions (gm_fake_git_repository_port_add_blob_mapping, fake_resolve_blob_at_head) that allow tests to pre-configure a map of file paths to expected blob OIDs, providing a realistic mock of Git resolution. Test Refactoring (core/tests/unit/test_edge.c): The previous custom mock function (mock_resolve_blob) for SHA resolution is removed. The test_edge_create_success unit test now uses the gm_fake_git_repository_port_t to set up the expected OIDs for "src/a.c" and "src/b.c" before calling the gm_edge_create API. Build System: meson.build is updated to include the source file for the fake Git repository port (core/tests/fakes/git/fake_git_repository_port.c) when building the test_edge executable. Miscellaneous The function gm_snprintf in core/include/gitmind/security/string.h is changed from static to static inline to potentially improve performance by allowing the compiler to substitute the function body at the call site.

This commit: * **Post-Commit Hook**: Initializes a live `libgit2`-backed `gm_git_repository_port` instance and uses it for all Git interactions, eliminating the old `resolve_blob`/`create_commit` shims. * **Journal Writer**: Replaces direct Git calls with port functions (`gm_git_repository_port_walk_commits` for parent lookup and `gm_git_repository_port_commit_create` for commit creation). * **Cleanup**: Standardizes header inclusions and removes obsolete type declarations and logic across several files (`post-commit.c`, `writer.c`, `reader.c`). * **Safety**: Updates `gm_fs_path_normalize_logical` to use `gm_memcpy_span` for improved buffer safety. --- AGENTS.md | 1 + .../gitmind/adapters/fs/posix_temp_adapter.h | 1 + .../adapters/git/libgit2_repository_port.h | 5 +- core/include/gitmind/ports/env_port.h | 1 - core/src/adapters/config/env_adapter.c | 1 + core/src/fs/path_utils.c | 12 +++-- core/src/hooks/post-commit.c | 48 +++++++++---------- core/src/journal/reader.c | 2 + core/src/journal/writer.c | 17 +++++-- core/src/ports/env_port.c | 3 ++ 10 files changed, 55 insertions(+), 36 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index dfbeb043..96da7934 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -420,6 +420,7 @@ See archives under `docs/activity/` for older logs. - Clang-tidy cleanup delivered: renamed the short `s1`…`s5` path segments, refreshed `walk_commits` naming, and forward-declared libgit2 types so include-cleaner stops shouting. - Fake git repository port now provides head branch lookup, per-ref commit walks, and commit-message reads via new helpers—tests can enqueue histories instead of skipping those seams. - Edge creation (basic + attributed) now resolves blob identities through `gm_git_repository_port`; goodbye `ctx->git_repo`/`git_ops` shims.

Kirby Ross" Date: Sat, 27 Sep 2025 03:04:23 -0700 Subject: [PATCH 13/56] feat(core): Migrate augment hooks to git_repository_port with commit-aware blob resolution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This set of changes represents a significant step in isolating the core logic from the underlying Git implementation by migrating augment hooks to the gm_git_repository_port abstraction layer. This feature introduces commit-aware blob resolution to the port, allowing the hooks to look up file content (blobs) at previous commits (HEAD~N) without using raw libgit2 calls. This greatly enhances the system's testability using the new fake port functionality. Core Abstraction and API Changes The core architectural change is the introduction of a new method to the gm_git_repository_port: A new virtual function, resolve_blob_at_commit, is added to core/include/gitmind/ports/git_repository_port.h. This function is implemented in the production adapter (libgit2_repository_port.c) and allows resolving a blob OID for a specific file path at a given commit OID. The function signatures for gm_hook_get_blob_sha and gm_hook_process_changed_file in core/include/gitmind/hooks/augment.h are updated to accept the new const gm_git_repository_port_t *repo_port instead of the old, un-abstracted git_repository *repo. Hook Logic Refactoring The augment hook implementation (core/src/hooks/augment.c) is completely refactored to use the new port functionality: gm_hook_get_blob_sha no longer uses git_revparse_single, git_commit_lookup, or git_tree_entry_bypath. For HEAD lookups (offset 0), it uses the existing gm_git_repository_port_resolve_blob_at_head. For HEAD~N lookups (offset >0), it first uses gm_git_repository_port_walk_commits to find the target commit OID, and then calls the new gm_git_repository_port_resolve_blob_at_commit. gm_hook_process_changed_file is updated to pass the repo_port to subsequent blob-fetching calls, ensuring the entire augments pipeline adheres to the abstraction. The post-commit.c hook is also updated to use the new repo_port when processing all changed files. Testing and Documentation Fake Git Port: The fake_git_repository_port is updated with a new helper, gm_fake_git_repository_port_add_commit_blob_mapping, which allows tests to set up explicit blob mappings for specific commit OIDs, ensuring fine-grained test coverage for the commit-aware lookup logic. Architecture Documentation: The docs/architecture/augments-system.md file is updated with a new sequence diagram and detailed text to illustrate the new, clean flow: Post-Commit Hook ➜ gm_git_repository_port ➜ Git (libgit2). This documents the successful separation of concerns. Agent Log: The AGENTS.md log is updated to reflect the completion of the augment helper port migration. --- AGENTS.md | 8 +- core/include/gitmind/hooks/augment.h | 41 +++-- .../gitmind/ports/git_repository_port.h | 17 ++ .../adapters/git/libgit2_repository_port.c | 43 +++++ core/src/hooks/augment.c | 165 +++++++++++++----- core/src/hooks/post-commit.c | 8 +- .../fakes/git/fake_git_repository_port.c | 90 ++++++++++ .../fakes/git/fake_git_repository_port.h | 6 + docs/architecture/augments-system.md | 32 +++- 9 files changed, 341 insertions(+), 69 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index cfaa4e44..46acb49a 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -422,7 +422,9 @@ See archives under `docs/activity/` for older logs. - Fake git repository port now provides head branch lookup, per-ref commit walks, and commit-message reads via new helpers—tests can enqueue histories instead of skipping those seams. - Edge creation (basic + attributed) now resolves blob identities through `gm_git_repository_port`; goodbye `ctx->git_repo`/`git_ops` shims.

Kirby Ross" Date: Sat, 27 Sep 2025 03:16:18 -0700 Subject: [PATCH 14/56] feat(core): Port merge detection to git_repository_port by adding commit_parent_count The diff represents a **feature implementation and migration** focused on fully isolating the Git functionality within the augmentation hooks from direct use of the `libgit2` library, moving it behind the **`gm_git_repository_port_t`** abstraction. Here is a breakdown of the key changes in the provided diff: * **`core/include/gitmind/ports/git_repository_port.h`**: * Adds a new virtual table function (`vtbl` entry) to the `gm_git_repository_port_vtbl` struct: `commit_parent_count`. * This function takes a `commit_oid` and a pointer to a `size_t` for the output. * A corresponding inline wrapper function, **`gm_git_repository_port_commit_parent_count`**, is added for safe, abstracted access to this new functionality. This is the crucial step that enables merge detection without direct `libgit2` calls. * **`core/src/adapters/git/libgit2_repository_port.c`**: * Implements the new function, **`commit_parent_count_impl`**, which uses `libgit2`'s `git_commit_lookup` and **`git_commit_parentcount`** to get the number of parents for a given commit OID. * The corresponding bridge function is added to the **`GM_LIBGIT2_REPOSITORY_PORT_VTBL`** to complete the concrete implementation for the `libgit2` adapter. * **`core/include/gitmind/hooks/augment.h`**: * Removes the direct inclusion of the `git2/types.h` header, eliminating a dependency on `libgit2` types in the public header. * Updates the signature of **`gm_hook_is_merge_commit`** to accept the abstracted **`const gm_git_repository_port_t *repo_port`** instead of the concrete `git_repository *repo`. * Updates the deprecated and preferred inline helper functions (`is_merge_commit`, `gm_augment_is_merge_commit`) to use the new port-based signature. * **`core/src/hooks/augment.c`**: * The implementation of **`gm_hook_is_merge_commit`** is completely rewritten to use the new **`gm_git_repository_port_t`**. It now resolves the HEAD branch, gets the tip OID using `gm_git_repository_port_reference_tip`, and finally calls the new **`gm_git_repository_port_commit_parent_count`** to determine if `parent_total > 1U`. * **`core/src/hooks/post-commit.c`**: * **Refactors the hook execution flow:** The `gm_libgit2_repository_port_create` call is moved up to initialize the `ctx.git_repo_port` immediately after the repository is initialized. This ensures the abstracted port is available early. * The `should_process_commit` function is updated to take `const gm_git_repository_port_t *repo_port` and now calls the ported `is_merge_commit` (which uses the port). * The logic to dispose of the repository port is centralized and performed whenever the hook exits (e.g., if it skips processing a merge or exits normally). * **`core/tests/fakes/git/fake_git_repository_port.h`** and **`core/tests/fakes/git/fake_git_repository_port.c`**: * The **fake Git adapter** is enhanced to support the new functionality. * A **`gm_fake_git_commit_entry_t`** struct now includes **`parent_count`** and an array of `parents` OIDs. * A new public function, **`gm_fake_git_repository_port_set_commit_parents`**, is added to allow tests to program the fake commit history. * The **`fake_commit_parent_count`** implementation is added to return the programmed `parent_count`. * A bug fix is included in **`fake_resolve_blob_at_head`** to check commit-scoped blob mappings when resolving HEAD, addressing an issue introduced in a previous commit's migration. * **`core/tests/unit/test_hook_augment.c`**: (New File) * Adds a new unit test suite specifically for the augment helpers using the new fake port. * Tests cover: * **`test_get_blob_sha_head_and_parent`**: Verifies both HEAD and HEAD~1 (parent) blob lookups via the port, confirming the blob resolution from the fake adapter works as expected. * **`test_is_merge_commit_detection`**: Verifies that a commit explicitly set with two parents is correctly identified as a merge. * **`test_is_merge_commit_linear_history`**: Verifies that a commit set with one parent is correctly identified as not a merge. * **`meson.build`**: * Adds the new test executable, **`test_hook_augment`**, to the build configuration and includes it in the list of tests to run. In summary, this diff **completes the migration** of Git merge detection into the abstraction layer, strengthens the architecture, and adds robust unit test coverage to lock in the new port-based behavior. --- AGENTS.md | 7 +- core/include/gitmind/hooks/augment.h | 16 +- .../gitmind/ports/git_repository_port.h | 16 ++ .../adapters/git/libgit2_repository_port.c | 29 +++ core/src/hooks/augment.c | 59 +++--- core/src/hooks/post-commit.c | 59 +++--- .../fakes/git/fake_git_repository_port.c | 100 +++++++++++ .../fakes/git/fake_git_repository_port.h | 7 + core/tests/unit/test_hook_augment.c | 168 ++++++++++++++++++ meson.build | 9 + 10 files changed, 410 insertions(+), 60 deletions(-) create mode 100644 core/tests/unit/test_hook_augment.c diff --git a/AGENTS.md b/AGENTS.md index 46acb49a..fe22df10 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -425,6 +425,7 @@ See archives under `docs/activity/` for older logs. - Hook journey note: fake git port fuels the edge tests;

Kirby Ross" Date: Sat, 27 Sep 2025 03:40:09 -0700 Subject: [PATCH 15/56] refactor(core): Retire legacy git_ops and git_repo from gm_context_t Retire the legacy 'git_ops' and 'git_repo' fields from 'gm_context_t'. This change completes the migration to a fully port-based core context, ensuring 'gm_context_t' is now pure and depends only on abstracted ports. The raw 'git_repository *' handle is now owned by the 'gm_cli_ctx_t' runtime, which handles its initialization and final cleanup. Key updates include: - The core 'gm_context_t' struct is cleaned of raw git dependencies. - CLI runtime ('main.c', 'cli_runtime.h') now holds and frees the raw repo handle. - The 'cache_rebuild' command is ported to use 'ctx->git_repo_port' to retrieve the current branch name. - Cache, journal, and benchmark tests are updated to remove assignments to the now-defunct 'ctx->git_repo'. --- AGENTS.md | 8 ++++---- apps/cli/cache_rebuild.c | 23 +++++++++++++--------- apps/cli/cli_runtime.h | 3 +++ apps/cli/main.c | 15 +++++++++----- apps/cli/main.md | 8 +++++--- benchmarks/wildebeest_stampede.c | 3 +-- core/include/gitmind/context.h | 10 ---------- core/tests/unit/test_cache_branch_limits.c | 1 - core/tests/unit/test_cache_meta.c | 1 - core/tests/unit/test_cache_query.c | 1 - core/tests/unit/test_journal_mixed_cbor.c | 2 +- docs/architecture/cache/builder.md | 2 +- 12 files changed, 39 insertions(+), 38 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index fe22df10..07b2caf9 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -426,7 +426,8 @@ See archives under `docs/activity/` for older logs. - Augment helpers now resolve HEAD/parent blob OIDs through the repository port (new `resolve_blob_at_commit` seam), and the fake git adapter learned commit-scoped blob mapping so tests can assert hook behavior without libgit2. - Architecture doc updated (`docs/architecture/augments-system.md`) with the post-commit ➜ repository-port wiring so future hooks keep the seam intact. - Merge detection runs through the port too: added `commit_parent_count`, rewired the post-commit hook to create/dispose the port up front, and landed a `test_hook_augment` suite that exercises HEAD/parent blob lookups and merge detection via the fake adapter. -- Next up (today, not tomorrow): hook the journal/cache tests to the upgraded fake, rerun clang-tidy to capture the delta, and start peeling edge modules off `ctx->git_repo`. +- `gm_context_t` is now strictly port-based—dropped the legacy `git_ops`/`git_repo` shim, handed raw libgit2 ownership to the CLI runtime, refreshed cache/journal tests, and kept the new shape green with `make ci-local`. +- Next up: finish scouring CLI + bench utilities for direct libgit2 calls, port them behind adapters, and keep clang-tidy quiet while we prep the PR. - Lesson logged: mirroring libgit2 semantics meant storing commit sequences per ref; keeping messages alongside the OIDs made the reader decode deterministic again. - Cap’n memo: espresso's on deck—once edge jumps ports, we raid the galley for celebratory biscotti. @@ -438,11 +439,10 @@ See archives under `docs/activity/` for older logs. - Stabilize and merge open PRs (#164, #165, #166, #167) after CI green; incorporate CodeRabbit actionable feedback and document any rejections under `docs/code-reviews/rejected-suggestions/`. - Add focused tests: journal base64 encode/decode roundtrip, `gm_snprintf` truncation behavior, and OID-based equality/lookup paths in cache and hooks. - Silence remaining clang-tidy warnings by fixing short parameter names, pruning redundant includes, and implementing the fake git port’s head/commit-walk seams. -- Retire the legacy `git_ops`/`git_repo` fields from `gm_context_t` once remaining call sites move to ports. - Audit other hook helpers (diff runner, env) for direct libgit2 usage and port them; parallel update CLI hook installer if needed. - Expand docs beyond AUGMENTS (e.g., hooks install guide) to reference the repository port seam instead of raw libgit2 handles. -- Sweep for any lingering `ctx->git_repo` or `ctx->git_ops` references and delete the legacy struct once nothing depends on it. -- Document the new port usage in `docs/architecture/hooks` (or add a note if missing) so future migrations follow the same pattern. +- Sweep for off-the-path libgit2 usage (`gm_cache_query_fanout`, benchmarks) and line up follow-up ports before cutting the PR. +- Document the port-based hook wiring in the broader docs set (install guide, CLI walkthrough) so the CLI/runtime split stays obvious. ## Vision Snapshot diff --git a/apps/cli/cache_rebuild.c b/apps/cli/cache_rebuild.c index a53edac9..bfd405e1 100644 --- a/apps/cli/cache_rebuild.c +++ b/apps/cli/cache_rebuild.c @@ -1,8 +1,6 @@ /* SPDX-License-Identifier: LicenseRef-MIND-UCAL-1.0 */ /* © 2025 J.

The function signature for 'gm_cache_query_fanout' was previously updated to accept 'gm_context_t *' instead of the raw 'git_repository *'.

Kirby Ross" Date: Sat, 27 Sep 2025 14:50:52 -0700 Subject: [PATCH 20/56] fix: Refactor libgit2 calls to use object IDs and iterative tree traversal; clean up filesystem utilities and CI prep. This commit delivers a substantial polish pass across core components: Benchmark Refactor: Replaced raw uint8_t SHA-1 arrays with the structured gm_oid_t in the wildebeest_stampede benchmark for cleaner object identity handling, specifically migrating the central "Mufasa" object to the new type. Recursive to Iterative: The memory-hungry recursive tree size calculation in libgit2_repository_port.c was replaced with an iterative, stack-based approach to prevent stack overflow errors on deeply nested repositories and improve robustness. Filesystem Security & Clarity: Addressed clang-tidy warnings by: Replacing raw memset with the safe helper gm_memset_safe in gm_fs_path_dirname and gm_fs_path_basename_append. Refining the path utility logic in path_utils.c with dedicated helpers (trim_trailing_slashes, find_last_separator, needs_path_separator) to resolve implicit boolean-to-integer conversions flagged by the static analyzer. POSIX Adapter Tidy: Explicitly defined _GNU_SOURCE in posix_temp_adapter.c and removed a redundant extern realpath declaration, satisfying include-cleaner and overall CI cleanliness. Augment & Journal Robustness: Standardized commit walking in gm_hook_get_blob_sha to consistently use the current branch head or HEAD as the starting reference, and improved error reporting in journal/writer.c to properly free allocated errors from failed walks. Test Helpers: Enhanced the fake Git repository port and test setup to better manage state and error handling. This work directly advances the next stage of porting libgit2 internals and resolves several key static analysis warnings in preparation for the upcoming cache migration PR. --- AGENTS.md | 5 + benchmarks/wildebeest_stampede.c | 14 +- core/src/adapters/fs/posix_temp_adapter.c | 4 +- .../adapters/git/libgit2_repository_port.c | 134 ++++++++++++------ core/src/fs/path_utils.c | 116 ++++++++++----- core/src/hooks/augment.c | 56 ++++---- core/src/journal/writer.c | 9 +- .../fakes/git/fake_git_repository_port.c | 46 +++--- core/tests/unit/test_cache_edge_map.c | 2 +- core/tests/unit/test_journal_mixed_cbor.c | 3 +- docs/architecture/augments-system.md | 3 + ...58c9f05de4f483c8c9a039df4b2307bba72ed97.md | 19 ++- ...195186ca1374dcef93a846f882a11ebbc7fb861.md | 35 +++++ 13 files changed, 306 insertions(+), 140 deletions(-) create mode 100644 docs/code-reviews/PR171/7195186ca1374dcef93a846f882a11ebbc7fb861.md diff --git a/AGENTS.md b/AGENTS.md index 07b2caf9..ae3f2d75 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -430,6 +430,11 @@ See archives under `docs/activity/` for older logs. - Next up: finish scouring CLI + bench utilities for direct libgit2 calls, port them behind adapters, and keep clang-tidy quiet while we prep the PR. - Lesson logged: mirroring libgit2 semantics meant storing commit sequences per ref; keeping messages alongside the OIDs made the reader decode deterministic again. - Cap’n memo: espresso's on deck—once edge jumps ports, we raid the galley for celebratory biscotti. +- Filesystem tidy sweep: replaced the lingering raw `memset` calls in `gm_fs_path_dirname`/`gm_fs_path_basename_append` with `gm_memset_safe`, added the explicit `separator_len` so the bool math stops tripping clang-tidy, and pulled in the security header for the helper prototypes. +- POSIX temp adapter now defines `_GNU_SOURCE` up front and trusts glibc's `realpath`; the redundant extern declaration is gone, keeping include-cleaner + tidy happy. +- Immediate next move: rerun `make ci-local` once these filesystem fixes settle, then chase the remaining bool-to-int clang-tidy nits in the staged benchmark + fake git port files before we go PR hunting. +- Lesson logged: tidy catches implicit bool arithmetic fast—introducing small helper variables beats sprinkling casts and keeps the intent readable for future hex refactors. +- Message in a bottle: future Cap’n, there’s cocoa in the galley—sip it while you double-check the tidy report before raising the PR flag. ## Next Steps (handoff checklist) - Complete on-disk cache migration to OID-only storage and naming; ensure rebuild and fallback readers handle both formats or gate with a one-time migration. diff --git a/benchmarks/wildebeest_stampede.c b/benchmarks/wildebeest_stampede.c index b7eef534..78ecd7cd 100644 --- a/benchmarks/wildebeest_stampede.c +++ b/benchmarks/wildebeest_stampede.c @@ -60,9 +60,9 @@ static void run_stampede(git_repository *repo, const char *branch, printf("Creating wildebeest edges...\n"); gm_edge_t *herd = malloc(wildebeest_count * sizeof(gm_edge_t)); - /* Mufasa's SHA (he's at the center of it all) */ - uint8_t mufasa_sha[GM_SHA1_SIZE]; - generate_wildebeest_sha(mufasa_sha); + /* Mufasa's identity (he's at the center of it all) */ + gm_oid_t mufasa_oid = {0}; + generate_wildebeest_sha(mufasa_oid.id); /* Generate the herd */ for (int i = 0; i < wildebeest_count; i++) { @@ -71,9 +71,9 @@ static void run_stampede(git_repository *repo, const char *branch, /* Half run TO Mufasa, half run FROM */ if (i % 2 == 0) { generate_wildebeest_sha(beast->src_sha); - memcpy(beast->tgt_sha, mufasa_sha, GM_SHA1_SIZE); + memcpy(beast->tgt_sha, mufasa_oid.id, GM_SHA1_SIZE); } else { - memcpy(beast->src_sha, mufasa_sha, GM_SHA1_SIZE); + memcpy(beast->src_sha, mufasa_oid.id, GM_SHA1_SIZE); generate_wildebeest_sha(beast->tgt_sha); } @@ -116,7 +116,7 @@ static void run_stampede(git_repository *repo, const char *branch, clock_t start = clock(); gm_cache_result_t scan_result = {0}; - gm_cache_query_fanout(&ctx, branch, mufasa_sha, &scan_result); + gm_cache_query_fanout(&ctx, branch, &mufasa_oid, &scan_result); clock_t end = clock(); result->journal_scan_ms = ((double)(end - start) / CLOCKS_PER_SEC) * 1000; @@ -135,7 +135,7 @@ static void run_stampede(git_repository *repo, const char *branch, start = clock(); gm_cache_result_t cache_result = {0}; - gm_cache_query_fanout(&ctx, branch, mufasa_sha, &cache_result); + gm_cache_query_fanout(&ctx, branch, &mufasa_oid, &cache_result); end = clock(); result->cache_query_ms = ((double)(end - start) / CLOCKS_PER_SEC) * 1000; diff --git a/core/src/adapters/fs/posix_temp_adapter.c b/core/src/adapters/fs/posix_temp_adapter.c index d402624a..c502eff5 100644 --- a/core/src/adapters/fs/posix_temp_adapter.c +++ b/core/src/adapters/fs/posix_temp_adapter.c @@ -1,6 +1,8 @@ /* SPDX-License-Identifier: LicenseRef-MIND-UCAL-1.0 */ /* © 2025 J.

Pair it with [Review_Seeding](./Review_Seeding.md) for tooling details. + +## 1. Generation + +1. **Auto seed (preferred):** + - Same-repo PRs: `.github/workflows/auto-seed-review.yml` seeds on open/reopen/sync and commits straight to the PR branch. + - Fork PRs: the workflow tries a bot push; if that fails it attaches the worksheet as an artifact and drops instructions in a comment. +2. **Manual seed:** run `make seed-review PR=` (requires `GITHUB_TOKEN`). Output path: `docs/code-reviews/PR/.md`. +3. **Naming:** file name is always the PR head commit SHA. Keep older worksheets around when the PR churns—they form the audit log. + +## 2. Editing the worksheet + +All seeded docs share the same skeleton: + +```markdown +## CODE REVIEW FEEDBACK +### +```text +...original feedback... +``` +{response} +``` + +Replace `{response}` with one of the response templates (Accepted/Rejected) and capture: + +- What changed (commits, follow-up PRs, doc updates) +- Why you accepted or declined the feedback +- Preventative steps or “future work” notes + +> 📝 **Tip:** When feedback spans multiple commits, list each SHA with a short description, e.g. `- fix: (abc1234)`. + +## 3. Decision markers + +The pre-push hook (`hooks/pre-push/worksheet_guard.py`) enforces: + +- Every section you touched must state `Decision: Accepted|Rejected` (plain text works). +- No stray `{response}` placeholders. +- Don’t delete sections unless you add a short note explaining the removal (e.g., duplicate of prior comment). + +If you really must bypass (e.g., to land a hotfix while docs lag behind): + +```bash +HOOKS_BYPASS=1 git push +``` + +Use sparingly; follow up with a proper decision update before closing the PR. + +## 4. What goes where + +| Location | Role | +| --- | --- | +| `docs/code-reviews/PR/.md` | Primary worksheet. One file per PR head. | +| `docs/code-reviews/ignored/` | Rationale docs when a CodeRabbit suggestion is intentionally declined without modifying the code. | +| `docs/tools/Review_Seeding.md` | Automation + seeding scripts. | +| `docs/tools/Review_Worksheet_Flow.md` | (This document) human workflow. | + +## 5. Merging & archiving + +- Keep the worksheet file in the final merge commit; it serves as provenance. +- If new worksheets arrive mid-review (CI re-seeding), keep the previous ones for history and work from the newest SHA. +- When major PRs land, consider adding a short summary to `docs/activity/_hexagonal.md` linking back to the worksheet. + +## 6. Frequently asked questions + +### “What if the hook still complains?” + +Check each heading you modified—many times the missing `Decision:` marker sits immediately above a fenced block. The guard is case-sensitive. + +### “Can I delete a worksheet?” + +Only if the PR is abandoned or superseded. Otherwise the guard expects the file. If you must remove it, flip `status: archive` to `deprecated`, add a paragraph explaining why, and update the pre-push guard if necessary. + +### “How do I reply from the worksheet?” + +Run `make apply-feedback FILES="docs/code-reviews/PR/*.md"` to post responses back into the PR threads (requires `GITHUB_TOKEN`). The script maps each section to its GitHub comment via metadata captured during seeding. + +## 7. Quick checklist before pushing + +- [ ] Worksheets exist for every commit you touched. +- [ ] Every `{response}` is replaced. +- [ ] Each section you edited includes `Decision:` and `Response:` (or the template wording). +- [ ] Docs lint passes: `make docs-verify`. +- [ ] CI: `make ci-local` (mirrors gate, keeps clang-tidy happy). + +Keeping the worksheet workflow tight means less friction for reviewers—and no more surprise `HOOKS_BYPASS` pushes.

Kirby Ross" Date: Sat, 27 Sep 2025 18:35:41 -0700 Subject: [PATCH 51/56] refactor: Standardize Repository Ownership, Cleanup, and OID Utility Abstraction This commit streamlines memory management by centralizing git_repository ownership outside of the libgit2 port, ensuring robust cleanup across the application lifecycle. It also introduces internal, non-libgit2 OID utility functions to decouple core cache logic from external dependencies. Core Changes Repository Ownership Consolidation: The git_repository * object is now explicitly managed in the gm_context_t (ctx->user_data in the CLI) or the calling function (in benchmarks and hooks). The libgit2_repository_port adapter's dispose function no longer calls git_repository_free(), making it a pure port-disposal function. This fixes multiple cleanup bugs in apps/cli/main.c, benchmarks/wildebeest_stampede.c, and core/src/hooks/post-commit.c by ensuring the underlying libgit2 repository is freed exactly once during context teardown. OID Utility Abstraction: Moved the OID utility functions (gm_raw_to_hex, gm_hex_to_raw, gm_hex_to_oid, gm_oid_equal) from internal libgit2 headers into core/src/cache/query.c. This eliminates the reliance on libgit2/oid.h in core cache query logic, improving isolation. The cache staleness check (gm_cache_is_stale) now uses the new internal gm_oid_equal for comparison, further detaching cache metadata handling from the libgit2 API. Path Utility Refinement: Significantly refactored the complex and highly-analyzed gm_fs_path_normalize_logical and gm_fs_path_dirname functions in core/src/fs/path_utils.c. Introduced smaller, dedicated helper functions (next_segment, push_segment, handle_segment, etc.) to reduce cognitive complexity, enforce stricter buffer checks, and improve overall correctness and maintainability. Cleanup and Robustness: Improved error handling in the journal reader (core/src/journal/reader.c) to correctly extract and free errors from the Git repository port. Replaced direct memcpy with gm_memcpy_span in test_journal_mixed_cbor.c for safer buffer manipulation in tests. Added a check for absolute paths in fake_fs_temp_port.c canonicalization to ensure test-case correctness. --- apps/cli/main.c | 13 + benchmarks/wildebeest_stampede.c | 1 + .../adapters/git/libgit2_repository_port.c | 4 - core/src/cache/query.c | 72 +++- core/src/edge/attributed.c | 1 + core/src/fs/path_utils.c | 380 ++++++++++++------ core/src/hooks/post-commit.c | 12 + core/src/journal/reader.c | 8 +- core/tests/fakes/fs/fake_fs_temp_port.c | 4 + core/tests/unit/test_cache_branch_limits.c | 1 + core/tests/unit/test_cache_meta.c | 1 + core/tests/unit/test_cache_query.c | 5 + core/tests/unit/test_cache_tree_size.c | 1 + core/tests/unit/test_journal_mixed_cbor.c | 7 +- ...195186ca1374dcef93a846f882a11ebbc7fb861.md | 60 +++ 15 files changed, 429 insertions(+), 141 deletions(-) create mode 100644 docs/code-reviews/PR171/7195186ca1374dcef93a846f882a11ebbc7fb861.md diff --git a/apps/cli/main.c b/apps/cli/main.c index f841dc30..a6151c0f 100644 --- a/apps/cli/main.c +++ b/apps/cli/main.c @@ -196,6 +196,7 @@ static int init_context(gm_context_t *ctx, gm_output_level_t level, git_libgit2_shutdown();

Kirby Ross" Date: Sat, 27 Sep 2025 22:36:14 -0700 Subject: [PATCH 55/56] feat(git): Implement safe non-fast-forward reference updates This commit primarily refines **reference handling** and **memory management** in the Git repository port and related services, particularly focusing on safe reference updates and resource cleanup. * **Non-Fast-Forward Reference Update Prevention:** * In `core/src/adapters/git/libgit2_repository_port.c`, the `reference_update_impl` function is completely refactored to explicitly prevent **non-fast-forward updates** when `spec->force` is `false`. * It now performs a lookup of the existing reference (`git_reference_lookup`), checks if the new target is a **descendant** of the current target using `git_graph_descendant_of`, and rejects the update with `GM_ERR_ALREADY_EXISTS` if it's not a fast-forward change. * If no reference exists (`GIT_ENOTFOUND`), it attempts to create it with `force = false`. If it exists and is a fast-forward, it updates the target using `git_reference_set_target`. * The `force` parameter in the **cache rebuild service** (`cache_update_ref`) and the **journal writer** (`flush_journal_batch`) is changed from `true` to **`false`** to leverage this new safety mechanism. * **Optimistic Locking in Journal Writer:** * The `flush_journal_batch` function in `core/src/journal/writer.c` is wrapped in a **two-attempt loop** to handle potential race conditions (optimistic locking). * If the reference update fails with `GM_ERR_ALREADY_EXISTS` (non-fast-forward), it indicates another process updated the journal's branch. The loop continues to the second attempt, effectively forcing a re-read of the parents for the next commit creation, before failing the write. * The creation of the journal commit (`create_journal_commit`) now correctly captures and returns the underlying error code from `gm_git_repository_port_commit_create`. * **Cache Rebuild Parent Commit Handling:** * The cache rebuild service (`cache_build_commit_and_update` and `cache_create_commit` in `core/src/app/cache/cache_rebuild_service.c`) is updated to **read the current cache ref tip** to use as the **parent commit** for the new cache commit. This correctly builds a commit history for the cache branch. * **Cleanup and Defensive Programming:** * The **fallback cleanup** logic is removed from `gm_git_repository_port_commit_message_dispose` in `core/include/gitmind/ports/git_repository_port.h` because the port implementation is responsible for disposing of the message, not the generic inline function. * Added the `_GNU_SOURCE` definition check in `core/src/adapters/fs/posix_temp_adapter.c`. * Introduced a helper function `dispose_repo_port` in `core/src/hooks/post-commit.c` to deduplicate and simplify port cleanup calls. * Added stricter size checks and defensive `gm_memset_safe` calls in the path utility functions (`gm_fs_path_normalize_logical`, `gm_fs_path_dirname`) and the fake Git repository port. * Used `gm_strcpy_safe` instead of `memcpy` for commit message copying in `fake_git_repository_port.c`. --- .../gitmind/ports/git_repository_port.h | 1 - core/src/adapters/fs/posix_temp_adapter.c | 2 + .../adapters/git/libgit2_repository_port.c | 62 ++++++++++++++++--- core/src/app/cache/cache_rebuild_service.c | 46 ++++++++++++-- core/src/fs/path_utils.c | 13 ++++ core/src/hooks/post-commit.c | 22 +++---- core/src/journal/writer.c | 47 +++++++++----- .../fakes/git/fake_git_repository_port.c | 8 +-- 8 files changed, 155 insertions(+), 46 deletions(-) diff --git a/core/include/gitmind/ports/git_repository_port.h b/core/include/gitmind/ports/git_repository_port.h index 420f155c..c852a130 100644 --- a/core/include/gitmind/ports/git_repository_port.h +++ b/core/include/gitmind/ports/git_repository_port.h @@ -185,7 +185,6 @@ static inline void gm_git_repository_port_commit_message_dispose( const gm_git_repository_port_t *port, char *message) { if (port == NULL || port->vtbl == NULL || port->vtbl->commit_message_dispose == NULL) { - free(message); return; } port->vtbl->commit_message_dispose(port->self, message); diff --git a/core/src/adapters/fs/posix_temp_adapter.c b/core/src/adapters/fs/posix_temp_adapter.c index c502eff5..13062155 100644 --- a/core/src/adapters/fs/posix_temp_adapter.c +++ b/core/src/adapters/fs/posix_temp_adapter.c @@ -1,7 +1,9 @@ /* SPDX-License-Identifier: LicenseRef-MIND-UCAL-1.0 */ /* © 2025 J.
