Reject manifests that do not contain a report.
isinstance(outputs, Mapping) accepts {}. If the summary file contains JSON null, summary == outputs.get("report") is true. The function can then accept a finalization marker for a successful manifest with no report.
Require the report key before comparing the values. Add a missing-report case to tests/unit/torch/puzzletron/test_width_scenarios.py.

Hydra 1.3.2 override grammar basic KEY ID KEY_SPECIAL DOT_PATH empty dotted path components parser
💡 Result:
In Hydra 1.3.2, the override grammar is defined via ANTLR4 files (specifically OverrideParser.g4 and OverrideLexer.g4) [1][2]. The grammar handles command-line overrides for configurations using specific tokens for keys, packages, and paths [3][4]. Key components of the grammar related to your query include: 1. Package Definition: The package rule is defined as ( | ID | KEY_SPECIAL | DOT_PATH) [3][1]. This indicates that a package can be empty (for the global package), an ID, a KEY_SPECIAL token (which allows characters like '$' and '_'), or a DOT_PATH [2][5]. 2. DOT_PATH and KEY_SPECIAL: - KEY_SPECIAL is defined as (CHAR|'_'|'$') (CHAR|DIGIT|'_'|'$')* [2][5]. - DOT_PATH is defined as (KEY_SPECIAL | INT_UNSIGNED) ('.' (KEY_SPECIAL | INT_UNSIGNED))+ [2][5]. This structure enforces that a dot-separated path consists of segments separated by dots. 3. Empty Dotted Path Components: The grammar does not explicitly support "empty" segments within a DOT_PATH (e.g., foo..bar). The DOT_PATH rule requires a KEY_SPECIAL or INT_UNSIGNED before and after each dot [2][5]. If a path contains empty components or is malformed, the ANTLR parser will typically fail to match the DOT_PATH token or the overall override rule, resulting in a parsing error. 4. Parsing Behavior: The parser uses these rules to structure overrides like key=value or group@package [3][4]. If you are encountering issues with "empty dotted path components," it is likely that the input string does not satisfy the DOT_PATH or package grammar definitions, leading the parser to reject the input or misidentify the key/package structure [1][6]. While some issues in Hydra related to "empty strings" in configurations have been reported [7], they are typically related to path resolution logic in the defaults list rather than the low-level ANTLR override grammar itself [7]. For detailed debugging of how specific strings are parsed, you can refer to the test suite in tests/test_overrides_parser.py, which includes parameterized tests for various key, package, and dot-path combinations [6].

💡 Result:
In the Hydra configuration framework, OverrideLexer.g4 and OverrideParser.g4 are ANTLR4 grammar files used to define the syntax for command-line overrides [1]. These files are compiled into Python code during the build process to facilitate the parsing of command-line arguments [1][2]. Within these grammar definitions, KEY_SPECIAL and DOT_PATH are lexical tokens that govern how keys and paths are interpreted in overrides [3][4]: - KEY_SPECIAL: Defined in OverrideLexer.g4 as (CHAR|'_'|'$') (CHAR|DIGIT|'_'|'$')*, this token allows identifiers to begin with specific characters like an underscore or dollar sign, effectively enabling keys that are otherwise valid in many contexts but may not strictly adhere to standard Python identifier rules [4][5]. - DOT_PATH: Defined as (KEY_SPECIAL | INT_UNSIGNED) ('.' (KEY_SPECIAL | INT_UNSIGNED))+, this token is used to represent hierarchical paths, such as hydra.launcher or db.name, by chaining these identifiers with dot separators [3][4]. Hydra version 1.3.2, released on February 23, 2023, incorporates these grammar definitions as part of its core functionality for managing complex configuration overrides [6][7]. The limitation that override keys must typically start with an alphabetic character or an underscore—rather than a digit—is a design constraint rooted in these lexical rules to ensure consistent behavior with Python syntax [5].

Reject empty dotted path components in _apply_override.
Hydra 1.3.2 rejects +foo.=1 and ++foo..bar=1, but _apply_override creates empty-string mapping keys. The later Hydra call prevents an invalid runtime configuration, but load_experiment_config can still return one directly. Reject empty components before mutating config, and add regression tests.

Update _apply_override to validate that the dotted key contains no empty
components before mutating config, rejecting inputs such as trailing, leading,
or consecutive dots with the existing invalid-override error behavior. Preserve
valid nested-path handling, and add regression tests covering these malformed
paths through load_experiment_config.

doesn't it assume that the user always names the artifacts dir as artifacts?

Got this remark from codex I'm approving this PR and leave it to the PR author whether to address this issue or not |

I added one overall comment from codex and one in the code about hardcoded "artifacts" dir; otherwise seems good (mostly reviewed with help from codex but also did random manual check on some files)

What does this PR do?
Puzzletron decides whether persisted orchestration work is reusable from manifests, attempts, artifacts, and post-MIP records that do not share a reliable identity. When configuration or execution context changes, stale results can therefore appear current; after a restart, artifact settling can start over.
This PR ties manifests, stage completions, and post-MIP outputs to stable identities for their effective configuration and producer lineage. Recovery reuses records only when they match the current run, rejects inconsistent registries, and preserves the original artifact-settling deadline across restarts.
This is the first in a series of smaller PRs extracted from Add Puzzletron v2 GPU quality baseline.
