Tools can declare how their output is compressed before it enters the context pack, replacing uniform handling. Open-threads 6.3 / ADR-0003. - core:tools/compression: ToolOutputCompressor interface, IdentityCompressor default, declarative OutputCompressionSpec + CompressionRule (StripBlankLines, StripLeadingWhitespace, DropMatching, HeadTail), and the pure DeclarativeCompressor engine (regexes compiled at construction; bypassOnError passes raw on non-zero exit; never throws on input). - Tool gains `outputCompressor` (default IdentityCompressor). FileReadTool strips blanks + leading whitespace; ShellTool strips blanks + head/tail. - SessionOrchestrator applies the resolved tool's compressor on the ToolResult -> ContextEntry path only. Raw output stays authoritative in the event log (invariant #6); compression is a pure function of (raw, exitCode, spec), so no new event and replay stays deterministic. - Spec is @Serializable/config-shaped (JSON round-trip tested). No custom-tool-from-config path exists today, so first-party tools wire in code; TOML-declared compression rides along when that path lands. Tier B (format-aware parsers: failures-only test output, git-log oneline) is a documented per-tool extension behind the interface, not built here.
