Proposal: Container Profile (corpus envelope) — spec §, example [draft]

[perlowja]

Draft spec PR for issue #77 — adds a Container Profile section: a transport envelope around MIF memory units, so a whole corpus (many memories + the source documents they derive from) moves as one artifact.

• records[] with kind: memory (a MIF memory unit, validated, levels apply) | document (e.g. an unmodified DoclingDocument).
• fact/event fold into MIF memories via a proposed memoryCategory term — no parallel schema.
• Corpus-level fields the unit doesn't carry: provenance (W3C-PROV), edit_chain/supersedes, compression_manifest, federation_cursor.
• Orthogonal to conformance levels. Adds examples/container-profile.corpus.json + CHANGELOG.

Draft — section number is editorial, and this is yours to shape/merge. The reference converters (mem0, letta, cognee, graphiti, mempalace) + docling import + validator are staged at perlowja/mif-converters (happy to transfer into the org — I'm a member but can't create public repos there; you'd need to accept the transfer). Closes nothing yet; pairs with #77.

@perlowja please target develop/v1.0.0 this is the working branch for the OKF and additional updates. Once we nailed that down I want to promote and release it.

Thank you.

Done — retargeted onto develop/v1.0.0 and rebased the proposal onto it (commit 19b37a6, the prior history had unrelated CI commits from main so I re-applied cleanly). It's a 3-file diff now and shows MERGEABLE:

• an editorial Container Profile (Corpus Envelope) — PROPOSED section in SPECIFICATION.md, slotted just before the Changelog;
• examples/container-profile.corpus.json;
• a CHANGELOG [Unreleased] entry.

I kept it as a proposed/editorial block rather than picking a section number, so you can promote/renumber it into the body wherever it fits the v1.0.0 cut. Staying draft until you've eyeballed placement.

@perlowja please reopen to main now that it is stable

[perlowja]

Reopened as #205 against main — GitHub locks this one closed (the develop/v1.0.0 base was deleted, so reopen returns "state cannot be changed"). #205 is the same branch rebased clean onto main: I dropped the inline changelog block that develop/v1.0.0 had already migrated into CHANGELOG.md, moved the proposed entry under ## [Unreleased], and re-validated examples/container-profile.corpus.json. Net diff is the same 3 files. Ready for your review on the cut whenever. Two things I'm still standing by on: (1) where memoryCategory should live — constrained ontology vocab vs. envelope-level enum — so I align the spec § and the converters to whatever you stabilized; (2) the mif-converters org transfer, the moment member public-repo creation is enabled.
