thinking carefully... i'm looking at concept.md, open-questions.md, and AGENTS.md . the core
|
|
tension seems to be "simple feel vs. robust future proofing."
|
|
|
|
i see three high-risk areas stemming from the confluence of tech choices and
|
|
philosophical constraints.
|
|
|
|
the first is integrating activitypub/fedify while keeping federation disabled
|
|
(lines 81-83 in concept.md). the risk here isn't just that it's "upfront cost is
|
|
minimal," but rather the operational overhead of managing a protocol layer that
|
|
could suddenly be flipped on, which introduces non-trivial state management and
|
|
dependency complexity even if the feature is inert. making those URIs standard
|
|
from day one sounds good, but keeping them "off" while carrying the plumbing for
|
|
"on" creates latent complexity debt.
|
|
|
|
mitigation: define an extremely explicit, versioned configuration flag (e.g.,
|
|
activitypub_federation_enabled: false) checked at runtime by a monolithic routing
|
|
service, not loosely scattered. if this flag is ever toggled in production (even
|
|
for staging), the code path executing federation logic must be instantly testable
|
|
and roll-back friendly via config change alone.
|
|
|
|
the second big risk is the background/resumable upload pipeline (tus.io, lines
|
|
91-95). meta's perceived "instantness" versus a distributed upload mechanism is a
|
|
major user experience divergence. while the architecture supports it,
|
|
implementation complexity skyrockets when considering edge cases: network drops
|
|
mid-upload across multiple background processing contexts (ios background tasks,
|
|
android workmanager) combined with filesystem/s3 migration (line 52). state
|
|
synchronization for resumable uploads across these heterogeneous environments is
|
|
hard.
|
|
|
|
mitigation: start by locking down the mobile client's upload state caching locally
|
|
(e.g., using a simple encrypted sqlite file on the client device) before tackling
|
|
server-side resilience for version 1. initial V1 should prioritize making the
|
|
upload appear instant to the user via local caching, and only push the full
|
|
resiliency layer post-MVP inside a tight scope.
|
|
|
|
the third risk is unifying the "no hierarchy" value with the feature set,
|
|
specifically around reactions and potential future comments. in concept.md (lines
|
|
122-139) and open-questions.md, there's a constant pivot away from counts/public
|
|
visibility (reactions are stored as user + post + emoji + timestamp, not counters,
|
|
confirmed in closed section 32). while this protects the value statement against
|
|
"dopamine grift," it heavily complicates feed sorting/discoverability if those
|
|
values ever become necessary. the user base is small, but scaling this philosophy
|
|
becomes difficult.
|
|
|
|
mitigation: codify the "no counts" rule as an immutable architectural constraint
|
|
that is flagged in the AGENTS.md (line 74) and enforced by linting checks against
|
|
any future PR that introduces a counter field for engagement. if the community
|
|
later demands "what are people thinking?" (i.e., counts), the system must require
|
|
a full re-architecture via a staged 'v2 migration' rather than incremental feature
|
|
creep.
|
|
|
|
i identified three risks:
|
|
1. activitypub plumbing complexity with federation off.
|
|
2. complex state synchronization for resumable uploads across mobile platforms.
|
|
3. maintaining "no hierarchy" by forbidding engagement counters entirely.
