fix: close the three residual findings from the 2026-10-20 security audit - #52
Conversation
…udit Completes the audit follow-up left open after #50 and #51: - csync.Map no longer exposes a value-receiver JSONSchemaAlias that copies its own mutex (go vet copylocks). The config JSON schema is now produced by a Reflector.Mapper in the schema command, which also fixes the slash-containing $defs key that broke JSON Pointer $ref resolution for provider entries. - NewFetchTool/NewDownloadTool accept the config so their no-client fallback builds a fail-closed secured client that honors allow_raw_ips and ip_allow_list instead of silently ignoring them. - Security docs no longer point at stale internal/ paths, and the startup symlink-resolution section describes what the code actually does (resolution happens after config parsing, before store construction). ஃ Generated with Phosphor Assisted-by: Phosphor:CYBER-FROST-3.8-EXL3-SAGE-3.87bpw

Review comments at @docs/security/ENVIRONMENT_HARDENING.md:
- Line 457: Quote the regular expression passed to -run in the documented go
test command so the shell treats the pipe-separated test names as one argument
and runs the complete test set.
Review comments at @docs/security/WORKSPACE_HARDENING.md:
- Around line 250-255: Update the workspace-root timing description to
distinguish initial config-path parsing from the later workspace-config merge:
state that symlink resolution occurs after the initial paths are parsed and
before ConfigStore construction, and that the workspace config is merged after
ConfigStore construction but before providers are wired.
Review comments at @internal/cmd/schema.go:
- Line 27: Update schema generation in schema.go so the schema used by schemaCmd
includes ProviderConfig in the root definitions and promotes its nested
definitions to the root, preserving resolution of nested references. Update
TestSchemaNoBrokenRefs and TestSchemaProvidersHasAdditionalProperties to
validate the schema produced by the same generation path as the command.

… schema CodeRabbit flagged that the providers mapper emits $ref: "#/$defs/ProviderConfig" while the mapper short-circuits the reflector before the value type is traversed, so ProviderConfig never lands in $defs and validators cannot resolve the reference. Add a newConfigSchema() helper that reflects ProviderConfig with ExpandedStruct and promotes its nested definitions to the root, and point both the schema command and the schema tests at it so they validate the exact document the command emits. Also quote the -run regex in the hardening docs so the documented test command is copy-pasteable, and clarify that the workspace config merge happens after ConfigStore construction. ஃ Generated with Phosphor Assisted-by: Phosphor:CYBER-FROST-3.8-EXL3-SAGE-3.87bpw

@CodeRabbit Re: the docstring-coverage pre-merge check (15.38% vs the 80% threshold) — this is a Go repository, not Python. Go has no docstrings; the idiom is godoc comments, and the functions touched by this diff carry them (see newSchemaReflector and newConfigSchema in internal/cmd/schema.go). The 80% docstring threshold doesn't map to Go conventions, so we're treating this check as not applicable. If there's a CodeRabbit config knob to skip docstring checks for Go paths, we'll set it on our side. |

Closes the three items left open after #50 and #51 wrapped the high/medium/low audit findings:
JSONSchemaAliascopied the map's ownsync.RWMutex. The method is removed; the config JSON schema is now produced by aReflector.Mapperin the schema command. Side benefit: provider entries now validate againstProviderConfigvia a clean$ref, and the generated schema no longer contains a slash-bearing$defskey that broke JSON Pointer resolution.NewFetchTool/NewDownloadToolnow take the config, so their no-client fallback builds a fail-closed secured client that honorsallow_raw_ips/ip_allow_listinstead of silently ignoring them.internal/file references corrected topkg/, and the startup symlink-resolution section now describes the actual behavior (resolution runs after config parsing, beforeConfigStoreconstruction).Embedded docs corpus regenerated (
