Why: prompts lived inline in Go (profile const, subagent string, squad
role one-liners, tool descriptions) - every copy change shipped code,
and task guidance like meeting-minutes quality lived permanently in the
base prompt whether or not the task was at hand.
Evidence: new prompts package tests (library integrity, default
assembly, skill triggering incl. attachment gate and command bypass,
priority supersession, override chain drift, command match, frontmatter
parse); composite make test green; runtime check on a live server
(40 modules across 7 layers, override round-trip, /minutes starts a
run instead of hitting the command bus).
Impact: 40 builtin modules as embed data (5 base + 1 env + 12 task
skills + 10 agent roles + 7 tool descriptions + 3 aux templates + 2
styles); migration v8 adds prompt_modules for user overrides with
basedOnVersion drift markers; ctxasm assembles multi-segment system
messages with per-module observability; subagent/squad/tool copy now
resolve from the library with inline fallbacks; skill commands surface
in the / menu and route to runs; default profile SystemPrompt empties
onto the library base; pins deps/agent-system-core to the contract
commit.

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.
Refs: feature/chat-live-quality task card.
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).
