Why: attachments were hard-truncated at 16k chars (most of a meeting
transcript silently dropped), injection carried no task guidance, the
builtin profile prompt was one generic line, subagents were capped at
300 chars, and docx tables were appended after all paragraphs losing
document order - together these produced sparse meeting minutes.
Evidence: go test ./... 16 packages ok incl. new ctxasm limit tests and
docx order assertions (heading->para->table->para); composite make test
green over the pinned combo.
Impact: attachment ceiling is 48k chars (settings
context.maxAttachmentChars), truncated on rune boundaries and observable
in the context report; the builtin prompt demands full-coverage
structured markdown for document tasks and upgrades stale builtin rows
on boot; budget.maxTokens now reaches the provider; subagents may write
full-length results; docx tables stay in place.

Why: T2 of the interaction foundation — activity cards as first-class state
objects behind the right-rail inbox (proposal D25): upload ingest cards
(SR-A5 failures explicit, artifact retrievable), HITL projection cards
(double-presence, ref-linked two-way sync), squad orchestration cards and
the mock #upload demo of the full card lifecycle.
Evidence: go test ./... green across 14 packages incl. new cardsvc suite
(lifecycle, action labels and idempotency, pin/dismiss, owner isolation,
resolve-by-ref idempotency) and updated migration test (v6 activity_cards,
both dialects); events flow through the session event buffer (persist, seq,
replay); receipts appended to the conversation timeline on card actions.
Impact: additive; cards disabled (SetCards nil) degenerates to the T0
baseline; upload cards persist at project level per the v1 inbox boundary
(conversation-scoped inbox; project-level aggregation is follow-up).
